ARTIFICIAL TOOTH` HOLDER Archibald Martin, Union City, N. J., assignor to The Dentists Supply Company of New York, New York, N. Y., a corporation of New York Application May 13, 1938, Serial N0. 207,693

5 Claims.

This invention relates to an articial tooth holder or mounting, and particularly to a type of holder wherein the individual tooth thereon may be raised for examination without disturbing the base plate. l The object of the present invention is to provide an eiiicient articial tooth holding device to overcome objections experienced with present day devices, while at the same time cheapening the manufacture of same.

"x" YMost of the present day shade and moldguides andartifcial tooth mounting devices' comprise a base member with a series oi individual tooth mounting members thereon, and which said members are not indivi-dually movable with respect to the base. In cases Where these tooth mounting devices are retained in drawers, traysA cipal objects a tooth mounting device having a base which will lie flat on the floor of a drawer or tray, and which when so positioned need never be raised or removed for inspecting or examing any particular tooth held thereon.

A further object of the invention is to provide a base of such` Width that the teeth and their supporting means are always within the area of said base.

A still further object of the invention is to ,provide an artificial tooth vholder in which each individual tooth is mounted on a separately movable member, so that it can be raised for 4examination without raising any other teeth.

Another object is to provide spring action in the tooth holding member so that it will be retained in the position in which it is placed. According to the invention, the artificial tooth holder comprises a sheet metal strip having an upstanding flange extending longitudinally thereof and bent to provide a bight or tubular part at the extremity of4 the flange, portions cut from said tube, a pintle in said tube, and tooth supporting members pivotally mounted on said pintle and adapted to receive a tooth on their outer ends.. The tooth supporting member may be in the form of a Cotter having its legs sprung apart at their youter ends to t into the socket (Cl. 20G-83) tooth thereon. The material around the cutout portions of the tube may be peened or flared in order to provide spring contact with the loop part of the pintle, in order that the pintle may snap from one position to another, and remain drawer or tray showing an arrangement of the i.

tooth holders therein,

Figure 2 is a topplan view of one of the tooth holders with the teeth resting against the base,

Figure 3 is an .enlarged vertical sectional View taken on the line 3-3 oi Figure 2,

Figure i is a view similar to Figure 3 showing the mannerv in which any individual tooth may be raised for examination,

Figure 5 is a side-view of. thecotter showing the legs of the same spread for providing gripping means'when inserted into the socket of an artiiicial tooth',

Figure 6 is a longitudinal view of the pint-le upon which-the cotters are mounted.

In illustrating and describing the present invention, the tooth holder has but two teeth mounted thereon, but it Will be understood that holders of any desired length may be provided to accommodate any number of partial or cornplete sets oi teeth.

The base member I I comprises a strip of sheet metal, and the face I2 thereof is bent to provide an upstanding flange I3. This iiange is substantially at right angles to the face l2, and at its outer extremity is provided with a tubular part I4. At certain intervals the tubular portion is cut-away, as at I6, and the remaining edges peened or ared outwardly, as at II. Spring cotters I8 have their loops I9 inserted into the openings so made, and a pintle 2| is passed through the tube and through the loops of said cotters, so that said cotters are pivotally mounted on said pintle.

The peened or ared edge I1 provides a spring contact with the cotter which has a movement from the position shown in Figure 3 to the position shown in Figure 4, while said flared edge will prevent any further upwardmovement of `the cotter beyond that shown in Figure 4. i

The sheet metal base has an aperture 25 immediately above each of the cut-out portions IG,

'that is to say, immediately above each of the grooves 24 and 2.6 for the insertion of a card 2!) upon which identifying data may be placed, and which may be inspected through the, apertures. 'Ihis identifying matter, of course, refers to and identifies the particular tooth on the adjacent Cotter, and gives the necessary information with respect to mold, shade, etc.

The base l! is of such width that the lower edges of the teeth A mounted on the cotters I8` tension so that the cotters supporting the teeth A will always remainin the position in which they are placed by the dentist, and when he desires to inspect any particular tooth for the purpose of matching, etc., he need only raise the individual tooth desired to be inspected, and when the examination is iinished the same can be pressed down to its normal position, shown in Figure 3. l

While the drawer of Figure 1 shows divisions 2li therein, it will be understood that the edges 3i) of the devices will prevent the piling up or 'disturbance of their position in the drawer'where no such partitions exist,

Of course, the tooth holder illustrated and described herein may be modified and changed in various ways Without departing from the invention herein set forth and hereafter claimed.

The invention is hereby claimed as follows:

l. An artificial tooth holder comprising a single piece sheet metal base bent to form an up standing longitudinal ange, a bight in said flange extending from end to end thereof, a pintle in said bight, spaced cut-out portions in said bight, a tooth supporting member pivotally mounted on said pintle at said cut-out portion,

and means on said member for holding a ltooth thereon.

2. An artificial tooth holder comprising a sin-'5 i gle piece sheet metal base bent 'to form an. upstanding longitudinal flange, a bight in said ange extending from end toY end thereof,A a*

-pintle in said bight, spaced cut-out portions in said bight, a tooth supporting member pivotally mounted on said pintle at said cut-out portion,

hanged means limiting the travel of said me'rnber, means for holding said member in any desired positionwithin" said limit,v and means on said member for holding a tooth thereon.

3. An artificial 'tooth holder comprising a sheet` metal base bent toy form .an upstanding flange with a tube-shaped part at its extremity, a por;-

tion cut from said tube, the material around said,"

cut-out portion iiared outwardly, arpintle insaid tube, and a Cotter pin pivotally mounted on said* pintle and having spring Contact with said flared material.

4. An artiiicial tooth holder comp-rising a sheet,y

metal base bent to form an upstanding .longituj i' dinal iiange bent at substantially right angles to said base and forming a hight, a pintle in said flange, a tooth supporting member pivotally mounted on said pintle, one Wall of said liange being extended to prevent the pivoting ofy said 30,@

member beyond a position substantially at'` right angles to said base. y

5. An artificial tooth holder comprising-av sheet l Y metal base bent to form an opstanding flange with a tube-shaped part atvits extremity,- a portion cut from said tube, the materialaround said cut-out portion ared outwardly, a pintle in said tube, and a cotter pin pivotally mounted on said 'n pintle and having spring Contact with said flared material, said flared -edge preventing the pivotal 40l movement of said cotter beyond a position'substantially at'right anglesto said base.
