' In Japan May 26, 1936 2 Claims. (Cl. 32-5) This invention relates to attachments for arti lever 2. The sleeve 1 is also preferably formed ?cial teeth ?xed in a vulcanite-bed in a kind of with a knob H which is adapted to be engaged bridge work, and has for its object to provide by the tip of a ?nger or a suitable tool so as to means for retaining the arti?cial teeth in posi move the sleeve on the holder 8. ‘ 5 tion in the mouth. The device is simple in con When arranging the arti?cial teeth in the struction, low in cost, easy in application and mouth, the lever 2 is positioned substantially ver reliable in function, by which sound teeth used tically as shown in Fig. 3, and consequently the as piers need not be arti?cially crowned and are not influenced by the forces set up in chewing with the arti?cial teeth. Other features and objects of the invention will be apparent to those skilled in the art upon a consideration of the following description and the accompanying drawing wherein several ex 15 emplary embodiments of the invention are disclosed. In the accompanying drawing:— ‘ Fig. 1 is a perspective view of an attachment according to the invention. Fig. 2 is a plan view of the attachment, illus trating the same applied to a pier tooth. Fig. 3 is a perspective view of the attachment embedded in a vulcanite-bed of arti?cial teeth, illustrating the position of the parts at the time 25 When it is to be applied to its place in the mouth. Fig. 4 is a perspective view of the attachment as shown in Fig. 3, illustrating the position of the parts when it is applied to its place in the mouth. Fig. 5 is a view similar to Fig. 2 illustrating a 30 modi?cation of the attachment. Referring to the drawing, I represents a clasp intended to be placed on the cheek side of a pier tooth. The clasp is connected with a lever 2 by 3 .means of a cross member 3 which is provided with a lug 4 adapted to engage against an under cut of the crown of the pier tooth. The cross member 3 carries an anchoring member 5 mov ably mounted thereon and adapted to be em 40 bedded in the vulcanite-bed of the arti?cial teeth. The anchoring member 5 is formed with a tongue 6 having an incline formed by bending the lat eral portion of said anchoring member on the side adjacent the lever 2, which co-operates with 45 the lever 2, when the arti?cial teeth are put in position in the mouth, to cause the clasp I to be pressed against the cheek side face of the tooth used as a pier, tending to thrust the lever 2 to ward the tongue side. 50 1 represents a sliding sleeve mounted on a holder 8 with toes 9 which are adapted to be em bedded in the vulcanite-bed of arti?cial teeth. The sleeve 1 is thus held in such a position as to be moved over the free end of the lever 2 when 55 the arti?cial teeth are arranged in position in the mouth. The sleeve 1 is formed with a clip III at one end for engaging the free end of the clasp I and the lug 4 are in an approximate ver tical position. When the arti?cial teeth set is put in position in the mouth, the lever 2 is turned 10 until it lies along the holder 8 and then the sleeve ‘l is moved on the holder over the free end of the lever 2. In this position of the lever 2, the clasp l is in ?rm engagement with the cheek side face of the pier tooth, and the lug 4 is in engagement 15 against the undercut of the crown of the pier tooth, whereby the arti?cial teeth set is secured in position in the mouth. If desired, the clasp I may be replaced, a clasp la embedded in the vulcanite-bed of the arti?cial 20 teeth and in this case, the tongue 6 may be omitted, as shown in Fig. 5 since the function thereof is not necessary in this modi?cation. Having now particularly described and ascer tained the nature of my said invention and in What manner the same is to be performed, I 25 claim:—— 1. An attachment device for arti?cial teeth comprising, a clasp for gripping a pier tooth, a lever connected with the clasp by means of a cross member, a lug carried by the cross member 30 adapted to engage an under-cut of the crown of the pier tooth, a vulcanite-bed having arti?cial teeth set therein, an anchor member ?xed to the vulcanite-bed rotatably supporting the cross member, an inclined tongue, said lever engaging the tongue on movement thereof to cause ‘the clasp to be urged against the pier tooth, a holder ?xed'to the vulcanite-bed and a sleeve slidably mounted on the holder adapted. to be moved over the free end of the lever for securing the lever 40 in a position along the holder. 2. An attachment device for arti?cial teeth comprising, a vulcanite-bed having the arti?cial teeth set therein, a clasp supported by the vul canite-bed for gripping the pier tooth, a cross member having a lug adapted to engage an under-cut of the crown of the pier tooth, means for rotatably supporting said cross-member on the vulcanite-bed, a lever ?xed to said cross 50 member, a holder having the ends thereof em bedded in the vulcanite-bed, and a sleeve slid ably mounted on the holder adapted to be moved over the free end of the lever for securing the lever in a position along the holder. 55 JUNZO TAGUCHI.
