Description
Field of the Invention
This invention relates to cleaning devices. More particularly, this invention relates to techniques and apparatus for cleaning coatings off of surfaces. Even more particularly, this invention relates to techniques and apparatus for cleaning coatings off the surface of tickets (e.g., lottery tickets) and game cards.
Background of the Invention
Lottery games have become extremely popular in recent years. Numerous states now have lottery games of one type or another and literally millions of lottery tickets are sold to the general public every year.
Typically a lottery ticket comprises a card on which there are printed numbers, letters, symbols, or some combination of characters which determine whether the purchaser of a particular card or ticket is entitled to a prize. The printed characters on the card are covered or hidden by an opaque coating or layer which is removable from the surface of the card or ticket by scraping or rubbing to reveal or expose the printed characters.
The coating on the card or ticket may be composed of various materials so long as the coating is visually opaque and relatively easy to remove with scraping or abrasion. Typically, a common type of coating used on such tickets comprises a blend of graphite particles and a wax (e.g., paraffin).
Similar types of tickets are also used, for example, by some grocery stores, drug stores, variety stores, etc. for their own types of games. For example, they may be used in games for giving away merchandise or other prizes.
Tickets of the type described herein are sold in various business establishments, typically at the check-out register, counter, bar, etc. Often times the purchaser or recipient of a ticket immediately scrapes or rubs the coating off the ticket while standing at the check-out register or counter. Naturally this takes time and causes delays in the check-out line.
The purchasers of the tickets normally use the edge of a coin to remove the coating to reveal the printed characters on the ticket. The coating shavings or fragments which result from scraping of a ticket are unsightly and can soil hands and clothing. Thus, it is undesirable for the shavings or fragments to be left on counters, tables, bar tops, etc.
There has not heretofore been provided a convenient, clean, and effective means for removing the coating from lottery or game tickets.
Summary of the Present Invention
In accordance with the present invention there is provided ticket cleaner apparatus which is adapted to quickly and efficiently remove the coating from the surface of a game ticket (e.g., a lottery ticket or the like) to reveal or expose characters on the ticket.
The apparatus of the invention comprises:
(a) a housing which includes an opening therein which is adapted to receive the ticket to be cleaned;
(b) a rotatable cleaning element supported in the housing;
(c) positioning means adapted to position the ticket within the housing in a manner such that the coating on the ticket is in contact with the cleaning element; and
(d) power means which is adapted to rotate the cleaning element while in contact with the coating.
When the ticket is inserted through the opening in the housing, the rotatable cleaning element removes the coating from the surface of the ticket to reveal the characters which are printed on the ticket. The apparatus gently removes the coating without damaging the ticket itself.
The ticket cleaner of this invention is very useful, for example, at check-out registers, check-out counters, etc. so that the purchasers of such game tickets can quickly determine whether they have won a prize. Use of this apparatus eliminates the need for the purchaser to search for an appropriate coin, fingernail file, etc. to scrape off the coating on the ticket.
As a result, use of the apparatus of this invention expedites check-out procedures and prevents the scraped coatings from soiling hands or clothing or cluttering the counters. The ticket cleaner apparatus is also very useful when it is necessary to clean the coating off of unsold game tickets for auditing purposes. Thus, large numbers of game tickets can be quickly and efficiently cleaned using this apparatus without harming the ticket and without creating a mess from the scraped off coatings.
Other advantages of the apparatus of this invention will be apparent from the following description.

Detailed Description of the Invention
In the accompanying drawings there is illustrated one embodiment of ticket cleaning apparatus 20 of the invention. The apparatus includes an outer housing comprising main body portion 22, front end portion 24, and rear end portion 26. Front portion 24 includes a slotted aperture or opening 25 through which a game ticket to be cleaned may be inserted, as explained in more detail hereafter.
Feet members 18 having threaded shanks 19 are illustrated in FIG. 6. The shanks 19 of the feet members are adapted to secure the housing portions to upright members 7 and 8, i.e. the shank 19 is adapted to extend upwardly through an opening 22a in housing portion 22, then through opening 24a in end portion 24, and then through opening 8a in upright member 8. Preferably opening 8a in upright 8 is threaded so that shank 19 is secured therein without the need for a nut or fastener. Similarly, the shank 19 of another foot member passes through registering openings in housing portion 22, end portion 26 and upright 8. In similar fashion the other two feet members secure the other side of the housing portions to upright member 7. Preferably, the pad or lower end of each foot member comprises rubber or other non-skid material.
Between the upright support members 7 and 8 there is supported a rotatable cleaning element 10. This is also illustrated in FIG. 10. Preferably cleaning element 10 comprises a cylindrical roll which is mounted transversely with respect to the longitudinal center line of the apparatus 20.
A toothed gear member 14 is secured to one end of the cleaning element. The gear member is fastened to the cleaning element such that rotation of the gear member causes rotation of the cleaning element.
An electric motor 11 is also supported between the upright members 7 and 8. A toothed gear member 15 is fastened to the output shaft 11a of the motor (as illustrated in FIG. 11). Gear member 15 is adapted to engage gear member 14 and thereby drive cleaning element 10 in a rotating manner.
The electric motor 11 may be powered by A.C. or D.C. current. For example, it may be powered by a D.C. battery, or it may be powered by A.C. current which has been converted to D.C. current through an appropriate adaptor 13.
FIG. 7 is an elevational view of upright support 7. The various openings which are visible in this view are for mounting the motor, cleaning element, and micro-switch as well as for passage of electrical wires to the motor and micro-switch. FIG. 8 is an elevational view of upright support 8. The two openings which are visible in the plate are for mounting of the motor and the cleaning element.
The ticket guide or positioning assembly 12 is illustrated in the elevational views of FIGS. 12 and 13. The leading end of the assembly is also visible in FIG. 4. Basically the guide assembly includes horizontal plate members 12a and 12b which are spaced-apart and parallel to each other. The spacing between the plates is preferably only slightly greater than the thickness of the game ticket 30 to be cleaned. The leading or front ends of the plates are flared away from each other to facilitate sliding entry of the ticket 30 between the plates as illustrated in FIG. 13. Stop member 12c serves as an effective limit to the extent or distance which the ticket may be inserted into the apparatus.
As illustrated in FIG. 13, the periphery of the cleaning element 10 contacts the upper surface of ticket 30, and the rotation of the cleaning element causes the coating on the upper surface of the ticket to be scraped or abraded away, thereby revealing the printed characters on the upper surface of the ticket. The guide of positioning assembly 12 assures that the ticket 30 is maintained in proper position relative to the periphery of the cleaning element 10 as the ticket is inserted into the apparatus.
The pressure of the cleaning element against the upper surface of the ticket is such that the coating on the ticket is scraped or abraded away without causing physical damage to the characters or symbols printed on the ticket itself.
Preferably a micro-switch 9, having roller activator 9a, is positioned near the leading end of guide assembly 12 as illustrated in FIG. 4. As the ticket is inserted into the guide assembly the ticket urges roller 9a upwardly to close the switch. This then activates the motor 11 to begin rotation of cleaning element 10. When the ticket has been cleaned and is withdrawn from the guide assembly, the roller 9a is urged downwardly by spring 9b (shown in FIG. 9) so that the micro-switch opens and the motor stops. The micro-switch is connected between the motor 11 and the power source. Wires 9c which are visible in the drawings connect between the micro-switch and the power source.
The cleaning element preferably includes brush means on its periphery. The brush means may be composed of various types of materials, such as hair bristles (e.g., horse hair), plastic (e.g., nylon), or metal bristles (e.g., brass, steel, etc.). Other equivalent materials, or combinations of materials, may also be used, if desired.
Other variants are possible without departing from the scope of this invention. For example, the power means may be a hand operated crank instead of an electric motor. Also, more than one cleaning element may be used, if desired. It is also possible to use an endless belt for the cleaning element instead of a roll.
