Description
Background of the Invention
1. Field of the Invention
This invention relates to a kit for cleaning phonograph records which includes a record vacuum cleaning attachment apparatus for attachment to a vacuum cleaner for safely removing dirt, dust, grime and chemicals suspended in cleaning fluid without damaging the playing surface of the phonograph record.
2. Description of the Related Arts
Used and neglected phonographs records are found in most homes and can be purchased by audio enthusiasts and record collectors at rummage sales, flea markets, garage sales, used record stores and at popular record conventions where thousands of old records are gathered in one place and offered for public sale.
Most old records have suffered abuse and neglect and have picked up some form of dirt, dust, grease, grime and chemical residue which should be chemically removed for enhanced audio enjoyment. In the course of operation of the inventor's business of selling collectable out of print records by mail, it has become apparent that abused records could be restored to a higher degree of fidelity and listening enjoyment by cleaning the records. The restored records bring a higher price on the market and induce customers to repeat purchases on the basis of confidence that they would get a listenable and attractive looking phonograph record.
In about 1975 an English company, Keith Monks Audio, began marketing a cleaning system for washing and cleaning phonograph records. The machine is a complicated electromechanical mechanism and includes a liquid pump, vacuum pump, power turntable and geared vacuum headarm. The machine is retailed for approximately $1,200.00. The machine is complex with many moving parts which may fail and the price is too high for many audio enthusiasts and small record collectors.
Two other companies have had some success in marketing integrated systems of pumps, vacuum pickups and turntables, but those systems are expensive. The first, the Nitty-Gritty Company offers several models of varying complexity that range in retail price from about $250.00 to $700.00. The other, the VPI Co. also offers an integrated record cleaning system that cleans and vacuums records inside a small console for approximately $350.00.
Other phonograph record vacuum cleaning devices are disclosed in U.S. Pat. Nos. 4,198,061 and 3,218,082. Also, brush type record cleaners are disclosed in U.S. Pat. Nos. 4,332,050, 2,977,127, 2,296,156, British Pat. G.B. No. 2,087,125A and German Patent DT No. 2922-397.
In particular, U.S. Pat. No. 3,218,082 issued to Taylor, et al. on Nov. 16, 1965 disclosed a "Vacuum Cleaner Attachment For Record Player" which mounts onthe side of a turntable and constantly vacuums the record while it is being played. The disadvantage of the Taylor, et al. invention is that it interferes with the playing of the record by introducing noise when the record is being played. Also, the Taylor, et al. invention must be permanenty mounted on the side of the turntable and therefore cannot be used with existing turntable platters. In addition, although capable of removing dust and loose particles the Taylor, et al. invention cannot remove grease, grime and chemicals from the playing surface of the phonograph record.
U.S. Pat. No. 4,198,061 issued to Dunn on Apr. 15, 1980 discloses an "Electrostatic-Vacuum Record Cleaning Apparatus" which imparts a static charge to dust and particles on the surface of the record to allow the dust and particles to be removed by a blower/vacuum device. Like the Taylor invention discussed above, the Dunn invention mounts on the side of the turntable. Also, the Dunn invention uses an electrostatic charge, a blower and a vacuum but it does not use cleaning fluid. Its operation is extremely complex and although capable of electrostatically removing dust particles and some loose dirt, like the Taylor invention, it is incapable of removing grease, chemicals, and grime adhered to the playing surface of the phonograph record.
It is an object of the present invention to provide an inexpensive and relatively simple apparatus and kit which uses an inert cleaning fluid to clean the playing surface of phonograph records and a means for vacuuming the record to quickly and completely remove the dirt, dust, grease, grime and chemicals suspended in cleaning fluid and is easy to use, reliable, adjustable for all sized records and does not damage the playing surface of the phonograph records.
Summary of the Invention
Briefly described, the present invention includes a kit for cleaning phonograph records which includes cleaning fluid, a brush and a record vacuum cleaning attachment apparatus. The record vacuum cleaning attachment apparatus includes a tube which is closed at one end, and an aperture for mounting the closed end onto the central spindle of a rotatable turntable. An adjustable separation means separates the tube from the surface of the phonograph record while pressing the phonograph record against the rotatable turntable. The record vacuum cleaning attachment apparatus is adapted to attach to a wet/dry shop vacuum cleaner at its other end, the vacuum causes a suction to emanate from a longitudinal slot in the lower surface of the record vacuum cleaning attachment apparatus. The suction allows the apparatus to safely remove the dirt, dust, grease, grime and chemicals which are suspended in the cleaning fluid on the playing surface of the phonograph record.

Detailed Description of the Preferred Embodiment
During the course this description like numbers will be used to refer to like elements according to the different figures which illustrate the invention.
A preferred kit 10 for cleaning a phonograph record 45 according to the present invention is illustrated in FIG. 1. The preferred kit 10 may be packaged in a container 11 and includes cleaning fluid 22 in bottle 23 for loosening, dissolving and suspending dirt, dust, grime, grease and chemicals 52 on the playing surface 46 of the phonograph record 45. The preferred cleaning fluid 22 includes an aqueous solution of p-tertiary-octylphenoxy polyethyl alcohol mixed in a ratio of about 5 ml per liter of water. A concentrated solution of p-tertiary-octylphenoxy polyethyl alcohol is sold under the mark Kodak Photo-Flow 200 solution and may be diluted in a ratio of approximately 6 U.S. gallons of water for each four (4) fluid ounce (118 ml) container.
Kit 10 also includes a brush 14 for spreading the cleaning fluid 22 on the playing surface 46 of phonograph record 45 and for loosening, dissolving and suspending the dirt, dust, grease, grime and chemicals 52 on the playing surface 46 of the phonograph record 45. The brush 14 preferably is approximately 5 inches long and about a 1/2 inch wide with long soft bristles 15, such as the brush marketed by AKG Audio, Inc. under the mark "WATTS RECORD WASH BRUSH".
The preferred kit 10 also includes a preferred record vacuum cleaning attachment apparatus 12 which is adapted to be attached to a standard nozzle 60 of wet-dry shop vacuum cleaner 16 and is used to safely remove dirt, dust, grease, grime and chemicals 52 suspended in the cleaning fluid 22 without damaging the playing surface 46 of the phonograph record 45.
As illustrated in FIGS. 2, and FIGS. 3A through 3E, the preferred record vacuum cleaning attachment apparatus 12 includes a tube 24 which has a first end 26, a second end 28, a hollow interior 29, a top surface 30 and a bottom surface 32. Tube 24 preferably is approximately 9 inches long and has an inside diameter of about 1 and 7/32 inches, an outside diameter of about 1 and 1/2 inches and is made from a clear or opaque plastic material. A spindle mounting aperture 34 is included on the bottom surface 32 of the first end 26 of tube 24 for mounting the record vacuum cleaning attachment apparatus 12 onto the central spindle 20 of a rotatable turntable platter 18 for phonograph records 45, as illustrated in FIGS. 4A through 6. Spindle mounting aperture 34 has a diameter of approximately 5/16 inches and its center is located on the bottom surface 32 about 13/16 inches from the first end 26 of tube 24.
The preferred record vacuum cleaning apparatus 12 also includes a means for separating tube 24 from the playing surface 46 of record 45 which includes an interior separation means 36 and an exterior separation means 42. The interior separation means 36 is attached to the bottom portion 32 of tube 24 between the spindle mounting aperture 34 and the portion of the bottom surface 32 of tube 24 which covers the playing surface 46 of phonograph record 45 when the phonograph record 45 is placed through spindle on rotatable platter 18 and the vacuum cleaning attachment apparatus 12 is mounted onto spindle 20 by means of the spindle mounting aperture 34, as illustrated in FIGS. 4C and 4D. Preferably, the interior separation means 36 is mounted about 1 and 3/8 inches from the center of spindle mounting aperture 34 toward the second end 28. The exterior separation means 42 is slidably attached to the bottom surface 2 of tube between the interior separation means 36 and the second end 28 of tube 24.
The interior separation means 36 and the exterior separation means 42 are preferably both attached to tube 24 by collars 38 and 40, respectively. Collar 38 attaches interior separation means 36 to tube 24 and is positioned near the first end of the tube and preferably fixed to the exterior of tube 24 by glue or some other means. Collar 38 preferably is attached at a point on tube 24 which covers the label 47 of phonogrpah record 45 whenever the record vacuum attachment apparatus 12 is mounted on rotatable turntable platter 18 by spindle mounting aperture 34.
Collar 40 slidably locks to hold exterior separation means 42 to tube 24 so that exterior separation means 42 on collar 40 can be slid, locked and held in position to accommodate phonograph records having different radii, such as, 7 inch 45's, 10 inch 78's and 12 inch long playing (LPs) records. The slidably locking collar 40 includes thumbscrew 66 which is threaded through the top of collar 40 and engages a slot 70 on the top surface of tube. Slot 70 has locking detents 62 that are set at about 3 and 1/2 inches, 5 inches, and 6 inches from the center of spindle mounting aperture in order to accommodate the popular 7 inch, 10 inch and 12 inch diameter records, respectively, so that collar 40 positions exterior separation means 42 on the outer edge 48 of the phonograph record 45 between the edge of phonograph record 45 and the outer edge of the playing surface 46. For the purpose of this application the outer edge of the playing surface is the first groove which contains information and is farthest away from label 47. As an alternative to using thumbscrew 66 a spring loaded stop means (not shown) may be utilized to engage detent 62 to allow the vacuum cleaning attachment apparatus 12 to be easily adjusted to accommodate various sized, 7 inch, 10 inch and 12 inch phonograph records 45.
The interior separation means 36 and the exterior separation means 42 on the bottoms of collars 38 and 40, respectively, include Teflon Bearings 41 mounted on the bottom of each collar 38 and 40. The Teflon Bearings 41 are preferably contained in a bearing box 43 which holds bearing 41 and which is recessed in the surface of the collars 38 and 40. As an alternative to Teflon Bearings, Teflon pads or metal or plastic rollers may be attached to the bottom surface of the collars 38 and 40, respectively. Whatever type separation means is used, however, the separation means must maintain a constant separation of about 1/32 of an inch between the bottom 32 of tube 24 and the playing surface 46 of phonograph record 45. The purpose of collars 38 and 40 is to create a base on the bottom surface 32 of tube 24 which is parallel to the playing surface 46 of the phonograph record 45. Collar 40 allows the exterior separation means 42 to be slidably adjusted so that it may rest on the outer edge 48 of various standard size records 45. If a rectangular or triangular tube 24 is used with a flat bottom surface 32, then an interior collar 38 would not be necessary since the interior separation means 36 could be attached directly to the flat bottom surface 32 of the tube 24.
Two Teflon bearings 41 are used on each collar 38 and 40, respectively, in order to maintain 5 points of contact with the surface of the record 45 to keep the playing surface 46 as flat as possible under tube 24, since the wet/dry shop vacuum cleaner 16 is actuated the suction from the apparatus 12 tends to cause record 45 to arch.
There may be many ways of making exterior separation means 40 slidably locking, and hold onto tube 24 other than the two examples discussed above. The combination of a sliding collar 40, longitudinal groove 70, locking detent 62 and thumbscrew 66 or a spring loaded stop means are only some of the variations on ways to slidably lock and holding the outer separation means 42 to the bottom surface 32 of tube 24 of the record vacuum cleaning attachment apparatus 12. Longitudinal groove 70 also serves the additional purpose of aligning the exterior separation means 42 so that the exterior separation means 42 is maintained parallel to the surface of the phonograph record 45 for all size records no matter how many times the exterior slidably locking holding collar 40 is adjusted.
The preferred record vacuum attachment apparatus 12 is attached to a standard nozzle 60 of a wet/dry shop vacuum cleaner 16 by an attachment means 54. Attachment means 54 includes a tapered entrance 56 on the interior 29 of the second end 28 of tube 24. The preferred interior dimensions of the tapered entrance 54 is approximately 1 and 1/4 inches at the opening of the tapered entrance 58 at the second end 28 of the tube 24, the entrance 58 tapers to an interior dimension of approximately 1 and 7/32 inches at about 1 inch from the opening of the tapered entrance 58 in the direction towards first end 26 of tube 24. This tapered entrance accommodates a standard size nozzle 60 of most wet/dry shop vacuum cleaners 16 now in production, however, it is contemplated that a greater taper may be included in entrance 58 to accommodate a greater variety of nozzles 60.
The bottom surface 32 of tube 24 includes an opening, preferably a longitudinal slot 50 which extends approximately parallel to the longitudinally axis of tube 24 and extends over the playing surface 46 of the phonograph record when the phonograph record is placed onto the spindle 20 of rotatable turntable platter 18 and the vacuum cleaning attaching apparatus 12 is mounted onto the platter 18 by the spindle mounting aperture 34. Preferably, the bottom surface 32 of the tube is beveled along the length of the opening of slot 50 towards the interior 29 of tube 24 in a smooth arc 58. The bevel of arc 58 preferably has a radius of curvature of approximately 36 inches, the center of the beveled arc and the center of the slot 50 is approximately 3 and 15/16 inches from the center of the spindle mounting aperture 34, and slot 40 has the length of approximately 3 and 7/8 inches. Preferably, the width W of longitudinal slot 50 is about 1/8 of an inch, as measured on the interior 29 surface of tube 24, Slot 50 tapers outward towards the lower outer surface 32 of tube 24 so the walls of slot 50 are angled approximately 90 degrees apart. Tube 24 is closed by a closure means which includes a small disk 44 on the interior 29 of tube 24 for closing the first end 26 of the tube 24 at a point between the interior edge of slot 50 and the spindle mounting aperture 34.
The major steps for use of the preferred kit 10 of the present invention are illustrated in FIGS. 3F and 4A through 6.
First, the phonogrpah record 45 is placed over the central spindle 20 of the rotatable turntable platter 18.
Second, as illustrated in FIG. 4A, cleaning fluid 22 from bottle 23 is applied to the playing surface 46 of the phonograph record 45.
Third, as illustrated in FIG. 4B, the cleaning fluid 22 is spread over the playing surface 46 of phonograph record 45 with a brush 14 to loosen, dissolve and suspend in the cleaning fluid 22 any dirt, dust, grease, grime and chemicals 52 on the playing surface of the phonograph record 45.
Fourth, as illustrated in FIGS. 4C and 6, the record vacuum cleaning attachment apparatus 12 is adjusted to accommodate the particular size phonograph record (7 inch, 10 inch or 12 inch) by slidably adjusting the collar 40 of the exterior separation means 42. Collar 40 is adjusted by loosening thumbscrew 66 and sliding the collar 40 so it is positioned over the appropriate locking detent 62 for the particular size phonograph record 45 in order for Teflon bearings 41 of exterior separation means 42 to be positioned over the outer edge 48 of phonograph record 45 when the record vacuum cleaning attachment means 12 is mounted onto the spindle 20 of the rotatable turntable platter 18.
Fifth, as illustrated in FIG. 1, 5 and 6, a wet/dry shop vacuum cleaner 16 is attached to the record vacuum cleaning attachment apparatus 12 by inserting nozzle 60 of the shop vacuum cleaner 16 into tapered entrance 58 of record vacuum cleaning attachment apparatus 12.
Sixth, as illustrated in FIGS. 4D and 6, the record vacuum cleaning attachment apparatus 12 and the attached nozzle 60 are mounted onto the central spindle 20 of rotatable platter 18 and over the playing surface 46 of phonograph record 45 so that the longitudinal slot 50 covers a radius of the upper playing surface 46 of phonograph record 45.
Seventh, as illustrated in FIG. 5, the wet/dry shop vacuum cleaner 16 is actuated to create a partial vacuum in the interior 29 of the record vacuum cleaning attachment apparatus 12 causing suction to emanate from longitudinal slot 50.
Eighth, as illustrated in FIG. 4D and 5, the record 45 and rotatable platter 18 are rotated, preferably by hand, relative to the longitudinal slot 50 of the record vacuum cleaning attachment apparatus 12 so that the slot 50 passes over the entire upper playing surface 46 of the record 45 and safely removes the dirt, dust, grease, grime and chemicals suspended in the cleaning fluid on the upper playing surface 46 of the phonograph record 45 without damaging the playing surface 46 of the phonograph record 45. Usually, two full rotations of the record 45 is sufficient.
Ninth, the playing surface 46 of the phonograph record 45 is buffed with a lint-free, soft cloth or towel. The entire cleaning operation takes about 40 seconds.
While the invention has been described with references to the preferred embodiment thereof, it will be appreciated by those or ordinary skill in the art that various changes may be made to the structure, components and materials of the present invention without departing from its spirit and scope.
