Description
Background of the Invention
This invention involves shoe taps and more particularly jingling clogging taps which hammer out a lively rhythm when attached to shoe soles during a country dance.
Clogging is a traditional dance that is most popular in the midwest and in the southern states of the United States of America. The steps might be generally classified as square dancing with the clogger, male and female, wearing metal rhythm makers on the toe and on the heel of their shoes. As the clogger goes through the square dancing steps, the dancer strikes the heel and the toe on the dance floor as each step is made, hammering a noisy but quite pleasant rhythm. When the cloggers are with the beat, it is the most impressive dance.
Prior commercial clogging devices use cast aluminum plates, one of which is a movable plate attached to the fixed plate usually by a single loose rivet in the middle. The top of the rivet is flat and is at the same plane as the movable plate. Flanges extend upwardly from the base plate along each side to prevent the movable plate from turning about on the rivet. The movable parts are struck together in a manner similar to castanets whenever they strike the floor, producing a loud metallic jingle sound with each strike. Present commercial clogging device tend to break easily and scar the floor due to the sharp edges that result from a break. Scarring also results from the sharp edges of the flat rivet, even when breakage does not occur. The nails may back out and tear up the floor. In addition, the joint, between the base plate flanges and the movable plate of present commercial clogging devices fill in with floor wax, dirt, or tar and quickly become inoperable to sound the jingle.

Summary of the Invention
It is an object of this invention to provide clogging devices, attachable to the shoes which stay firmly attached despite hard use.
It is an additional object of the present invention to provide a clogging device which does not scar the floor on which the dance is held.
It is an additional object of the present invention to provide a clogging device which when nailed to the shoe, the nails can not back out and scar the floor.
It is an object of the present invention to provide a clogging device which when attached to the heel or sole, will not crack, will provide no rough edges, and is essentially indestructible providing long wear and service without damage to the surface on which the dance is held.
It is a further object of the present invention to provide a clogging device which resists the collection of foreign materials in the mechanism which prevents the clogging device from jingling after extended use and even on surfaces that yield a "gummy" material depositing on the bottom of the taps.
This invention is a clogging tap device to be attached to the bottom of the heel or the toe or both the heel and the toe of a shoe. The device includes a base plate member having a front end and a back end, the direction between the ends being common to the direction of the length of the shoe or of the center line of the shoe. It is preferred that the base plate member be shaped in the form of a heel or a toe of a shoe to which it is to be fitted. The base plate is supplied with a plurality of holes, preferably about five holes which pass through the base plate, each hole being of a size to allow the shank of a nail or other fastener to fit through, but at the same time prevent the head from passing through. A tapping plate member is provided, preferably shaped to approximate the shape of the base plate and that of the heel or the toe of the shoe sole to which it is attached is provided. A hinge type attachment device including at least two rivet devices is provided to attach the tapping plate to the base plate while allowing the tapping plate to move, canting back and forth toward the front end and the back end. The tapping plate is provided with a plurality of holes through the tapping plate, one each aligned over every hole in the base plate. These holes through the tapping plate are of a size to allow the head of the nail or the fastener to pass through the hole in the tapping plate. It is preferred that these holes be of such size that the head of the nail or the fastener snugly fits or more preferably force fits through the hole in the tapping plate as the base plate is nailed to the sole or heel of the shoe.
It is preferred that the attachment means include at least two second holes through the tapping plate with a depressed area of the tapping plate around each of the second holes, the depression being on the surface away from the shoe bottom. A convex domed area of the tapping plate is provided around each of the second holes, the domed area being on the surface toward the shoe bottom. These domed areas provide a rocking pivot point for the rocking tapping plate. Second holes are provided through the base plate, one each aligned with each second hole through the topping plate and a rivet device is provided through the pairs of second holes to loosely attach and hinge the tapping plate to the base plate, allowing loose canting movement of the base plate front to back along the central axis of the shoe. The second holes are aligned to a line transverse to the central axis of the shoe. It is also preferred that sharp upturned knife-like edges be provided along the periphery of the base plate on the surface to bite into the side or heel of the shoe.

Description of Preferred Embodiments
FIG. 1 is a perspective view of shoe 10 to which clogging device 12 is attached to the toe portion of the sole 14 and a similarly constructed clogging device 16 is attached to heel 18. Each clogging device, 12 and 16, is attached to the sole or heel with nails 20 which are inserted through holes 22 and driven into the sole or heel under the device. Holes 22 are sized such that head 24 of nail 20 is snug or even forced fitted through the hole before being driven into the sole.
FIG. 2 is an full sized perspective view of clogging device 12 with holes 22 opening through tapping plate 26 which is cold rolled steel formed slightly convex toward the surface striking the ground. To attach device 12 to the bottom of the shoe, nails 20 are inserted so that the point extends through holes 22 and also through holes 28 which passes through base plate 30, illustrated in FIGS. 2 and 3. When nail 20 is driven and forced fitted through hole 22, it engages the upper surface of base plate 30 as the head is too large to pass through hole 28. Even if nail 20 backs out of its grip on the sole or heel to which it is nailed, it is prevented from passing out through hole 22, thus essentially eliminating any chance of scarring the floor. Tapping plate 26 is formed with concave depressions 32 and 34 which are annular in shape surrounding a second series of holes in plate 26 through which round headed rivets 36 and 38 are fixed. The top of rivets 36 and 38 do not extend pass the floor contacting surface of plate 26 preventing floor scarring. All outside exposed edges of plate 26 are rounded.
FIG. 3 illustrates the bottom of device 12 which is attached to the sole surface of the shoe. Base plate 30 is slightly dish shaped cold rolled steel with the concave surface toward the bottom of the shoe to which it is nailed. Upright sharp edged flange 40 extends around the periphery of the surface facing the shoe sole to engage and lock the plate onto the sole surface. Sharped edged flange 40 bites into the shoe sole or heel surface and reduces the tendency of movement between top 12 and the shoe surface. This removes much of the strain from nails 20 during dancing, and reduces the tendency of the nails to loosen. Holes 28 are of a size such that the head of nails 20 cannot fit through and when driven through the holes into the shoe soles, they fix device 12 to the shoe. End 42 of rivet 36 and end 44 of rivet 38 are crimped over to attach tapping plate 26 to base plate 30. It is important that crimpings 42 and 44 be accomplished to prevent the plates from separating, but not to prevent them from moving against each other. The crimpings are not made down the shank or rivets 36 and 38 to engage the surface of plate 30 so that the plates are not pushed tight together. This attachment is described as "loosely attached" throughout the specification and claims and is intended to denote strong attachment but sufficiently loose to allow rocking movement of tapping plate 26. Thus, crimpings 42 and 44 allow tapping plate 26 to cant along a line joining rivets 36 and 38 such that front end 46 of tapping plate 26 may cant to touch and clank against front end 48 of base plate 30. Likewise, back end 50 is free to cant and strike back end 52 of base plate 30. It is sufficient that plate cant and jingle without necessarily hitting both front and back of loose plate 30.
FIG. 4 illustrates the dome-like structure 54 which surrounds the hole in plate 26 through which rivet 36 passes crimped over the bottom at 42. Dome shape 54 is formed from the cold rolled steel plate and is depressed at 34 to form a convex downwardly shaped dome 54 between the plates. Since rivet 36 is attached loosely, plate 26 rocks on dome shape 54 allowing front end 46 to strike and jingle against front end 48 of base plate 30. Also dome 54 strikes against plate 26. FIG. 5 illustrates domes 54 and 56 on which tapping plate 26 rocks and jingles. Plate 26 rocks on pivot line joining domes 54 and 56 toward the viewer and away from the viewer.
