UNITED STATES GEORGE ALBERT HARPER, OF SHREVEPOR'I, LOUISIANA.
' DENTAL IMPRESSION TRAY.
Application filed July 25, 1923. Serial No. 653,735.
To all whom it may concern. T
Be it known that I, GEORGE A. hanrnn, a
citizen of the United States, and a resident Impression Trays, of which the following is a specification.
My present invention relates generally to artificial dentures and more particularly to an impression tray for taking a lower 1mpression in making artificial dentures, my .object being the provision of a tray adjust able for the purpose of fitting the lower jaw, which may be utilized with ease, facility and eii'ectiveness and in which the adjustable parts are separable to facilitate the movement from the mouth and be easily and quickly reassociated and adjusted to perfect adaptation to the impression after removal.
In the accompanying drawing illustrating my present invention and forming a part of this specification,
Figure 1 is a perspective view looking from the underside of my improved impression tray, 1
Figure 2 is a top plan view of the tray,
Figure 3 is an end view thereof,
Figure 4- is a side view of one of the sections removed, and
Figure 5 is a partial side view of other section.
Referring now to these figures my improved lower impression tray is like the usual tray generally of U-shape and is of channel form and is in accordance with my invention divided at an approximately central point into two curved side sections and 11 whose inner or meeting ends are joined by virtue of certain connections including extensions 12 carried by the inner end of the section 10 as shown in Figure 5 which are spaced apart and conformably curved to overlap the adjacent end of the section 11. These extensions 12 of the section 10 are moreover disposed upon opposite sides of an upright semicylindrical socket member 18, adjacent to which the end of section 10 has a projecting Wing 14 apertured as at 15.
In order to cooperate with the section 10, section 11 has at its inner meeting end an upright stud 16 adapted to movably interfit the socket 13 of section 10 providing for the completion of a vertical pivotal conthe nection by the use of a short readily removable sleeve 24- which telescopes the socket 13 and stud 16 as: in Figures 1 and 2. The section 11 is provided adjacent to the stud 16 with an outstanding wing 17 apertured as at 18 and adapted to oppose the wing 1 1-, it being noted that the apertures and 18 aline when the sections are in properly assembled relation as in Figures 1 to 3 inclusive so as to receive therethrough an adjusting screw 19. This adjusting screw is threaded through both of the openings, and the wings being somewhat flexible, adjustment of the screw permits the two sections 10 and 11 to be secured adjustably with their outer ends spaced apart more or less within certain limits. It will be noted from Figures 2 and 3 in particular that the wing 17 of section 11 is offset at its inner portion so as to permit one of the overlapping extensions 12 of section 10 to project onto the adjacent portion of the section 10 and it will be noted from Figures 1, 2 and 3 that the two wings 14 and 17 when 0011- nected in adjustable relation by the screw '19, form a handle by means of which the tray as a whole may be manipulated in the mouth. It will furthermore be obvious that itis simply necessary to withdraw the adjusting screw 19 and remove the pivot holding sleeve 24 in order that the two sections 10 and 11 may be readily disassociated and removed easily and quickly from the mouth one at a time subject to easy and quick readjustment and reassembly in perfect adaptation to the impression material after the latter is withdrawn.
In further accordance with my invention the sections 10 and 11 are provided at their free ends and at their inner sides with wings 20, each having a longitudinal slot 21 and each adjustably mounted on a stud 22 pro" jecting through the slot thereof for the re ception of a clamping nut These wings which are located upon the inner sides of the ends of the channel of the tray serve to hold and press the impression material carried by the tray in its practical use closely against the inner portion of the jaw, and for this purpose their angular relationship to the tray as well as the extent of their projection beyond the tray ends may be easily adjusted and controlled.
It is thus obvious that my improved tray is not only adjustable to fit jawsof different sizes so as to avoid the necessity of a multitude of different size trays, but it is obvious that such adjustment may be quickly and easily effected and that the Wings also are adjustable making it possible to press the impression material 01' compound firmly against the jaw in order to assure a more adaptable impression and better fitting plate.
I claim:

A dental impression tray of approximately U-shape, divided substantially at the center thereof and including a pair of side channels having pivot forming members at their inner meeting ends on which they are adjustable With respect to one another, said pivot forming members being detachably engageable With one another, and means to adjust and secure the two side sections in adjust d p sition,
2. A dental impression tray including a pair of curved side channels in endwise abutting relation, one of said channelshaving an upright stud and the other having an upright semicylindrical socket, said stud and socket being located at the meeting ends of the channels and forming a detachable pivotal connection therefor, detachable means to normally hold the stud Within the socket and a screw member for adjusting said channels and holding the same in adjusted position.
3. A dental impression tray including a pair of curved side channels in endwise abutting relation, one of said channels having an upright stud and the other having an upright semicylindrical socket, said stud and socket being located at the meeting ends of the channels and forming a detachable pivotal connection therefor, said channels having adjacent to their abutting ends outstanding opposed Wings provided with 1,51e,ese
apertures, and a connecting screw extending through mid apertures.
4. A dental impression tray of approximatel U-shape and of channel form, a pair of ad ustable pressure Wings disposed oppo site one another at the inner sides of the free ends of said tray, and supports for said Wings upon which the latter are movable lengthwise of the tray sides and rotatable as described.

A dental impression tray including a pair of curved side channels in endwise abutting relation, one of said channels having an upright stud and the other having an upright semicylindrical socket, said stud and socket being located at the meeting ends of the channels and forming a detachable pivotal connection therefor, detachable means to normally hold the stud within the socket, and detachable means to connect and support the pivoted channels in adjusted position.
7. A dental impression tray including a pair of curved side channels in endwise abutting relation, one of said channels having an upright stud and the other having an upright semicylindrical socket, said stud and socket being located at the meeting ends of the channels and forming a detachable pivotal connection therefor, and a sleeve telescoping the socket and the stud therein to hold the same in pivotal relation and readily removable therefrom.
