ARTIFICIAL-TOOTH HOLDER.

Application filed June. 25,

This invention, generally stated, relates to aholder for artificial teethand has more especial relation to a holder of this type, as used by dentists supply houses andthe like.

Holdersfor artificial teeth now upon the market without exception aremanufactured from metal, thus making the article more or less expensive. -Further, it is customary to have these holders mounted: upon .stands, whereby the teeth may be exhibited; F urther, these holdersas mounted upon stands cannot be conveniently packed in boxes for shipping purposes.

The leading object of the present nvention is to overcome the above described disadvantageous features and provide a holder of the character stated which may be made of'bakelite, fibre, rubber, or othersuitable material, and which is provided wlth artificial teeth receiving prongs or pegs which are embedded in the holder proper so that the artificial teeth when forced to place over the resilient prongs or pegs are firmly locked to place. s

A further object of the present invention resides in the provision of general details of construction and arrangement of parts for attaining the results sought by the lead ing object.

The invention consists of the novel construction hereinafter described and finally claimed.

The nature, characteristic features and scope of the invention will be more fully,

understood from the following description taken in connection with the accompanying drawings forming part hereof, and in which:

Fig. 1 is a view of a holder embodying the invention.

Fig. 2 is a top or plan view thereof.

Fig. 8 is a view of a slightly modified form of the invention; and

Fig.4 is a top or plan view thereof.

For the purpose of illustrating my invention I have shown in the accompanying drawings two forms. thereof which are at present preferred by me, since the same have been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of the 1927.

instrumentalities as, herein shown and descrlbed.

I Referring now to the drawings,and with more especial relation to Fig. 1, the reference numeral 1 designates an elongated, rec tangular backing plate made of bakelite, fibre, rubber, or other material. Spaced alongone of the broad, flat faces of the plate 1 are a plurality of artificialteeth receiving clips, prongs, or pegs. These clips, prongs, or pegs each comprise a metallic member of relatively thick wire or the like, split and bent to form a pair of opposed vertical members 2 which terminate at their upper ends in a pair of horizontally disposed members 3. These horizontal members 3 are embedded in the plate 1 and in case the plate is made of bakelite, rubber, or other moldable material, it is preferable to have the members 3 molded directly into the plate at the time of formation. The attaching devices thus formed are of inverted L-shape as may be clearly seen from an inspection of the drawings. In inserting a tooth upwardly over the split prongs of member 2 the rear face of the artificial tooth abuts against the forward face of the laterally against the opening through the tooth, Thus, longitudinal retaining pressure is exerted upon the tooth by the prongs, and at the same time endwise pressure is exerted against the tooth, thus firmly retaining the same in position, against the plate.

Referring now to Figs. 3 and 4., a slightly modified form is shown in which the plate 1 is exactly the same as the plate shown in the foregoing figures, However, the spaced, artificial tooth retaining prongs, pegs or clips which are designated 5 are not split as in the devices shown in the foregoing f figures, but comprise a single member especially adapted to receive an artificial tooth, and force the same back against the forward face of the plate 1, it of course being understood that the prongs are resilientv in nature and may, for instance, be wire or equivalent material. This forcing of the rear face of the tooth against the front face of the plate 1 serves to securely hold a tooth in place-so that jars and jolts will not dislodge the artificial teeth from the 7 plate. I In both the above cases the rectangular,

elongated plates are of a form convenient for the ready packing and shipment of artificial teeth, and at the same time are quite I efficient for the showing of artificial teeth Without the employment of a cabinet, as is frequently required in holders stamped from metal. V a

In addition to this advantage, the holders may be much more cheaply manufactured;

It'will now be apparent that I have devised a novel and useful construction "which embodies the features of advantage enamel a ted as desirable in the statement of the invention and the above description and while I have in the present instance shown and described the preferred embodiments thereof which have been found in practice to give satisfactory and reliable results, it it to be understood that thesame are susceptible of modification in various particu lars Without departing from the spirit or scope of the inventionorsacrificing any of its advantages. a t

lVhat I claim is:

. 1. An article of the character-stated comprising an elongated fiat 'plate of nonmetallic material one face of which plate isprovided with a plurality of spaced, in-

verted L-shaped clips, each of said clips being split to exert longitudinal pressure upon the interior of an artificial tooth as forced over thedepending prongs of said split clip. a p i MYER GHAREN.
