Description
a viter f @niet t. @tibia GEORGE HILLI-IURD, OF MEMPHIS, TENNESSEE.. Laim Patent No. 86,922, ma February/ 16, 1869.
IMPROVE!) DENTAL .mw-Bruce.
Tha Schedule referred to in these Letters Patient and making part of the same.
To all whom it mel/y concer/n Be it known that I, GEORGE HILL HURD, of" the city of Memphis, county of Shelby, and State of Tennessee, have invented a new and useful Dental Jaw- Brace; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had tothe annexed drawings, making a part of thisspecifcation.
Figure I is a perspective view, showing the an'ges Figure II is aperspective view, without the ilangesii.
Figure A, a view of the dental jaw-brace in position in the mouth.
B and O, body of jaw-brace, made of hard rubber.
a a a. a, flexible rubber cushions.
d d d d, short'anges, made of hard and soft rubber combined.
The nature of this invention consists in a new and improved constructed jaw-brace for use in the extract? ing or filling of teeth. It has been, up to the present time, the universal practice to use a commonl cork, if anything. But as it is too soft, and notadapted in shape, it is often mashed down, especially while the patient is under any ansthetic, makingit then impracticable to operate on the patient; and the cork is also liable to get into the patients throat. Another obj ection to the cork is, it absorbs the blood and saliva of the mouth. i y
rlhe object of my invention is to obviate these diiculties, and secure the jaws in the proper position at all times, and upon an entirely new principle, and making it easy for the teeth when biting hard. I also construct this. brace out of materialsthat are impervious to the blood for acids of the mouth To enable others to make and use my invention, I will describe its construction and operation.
Iv make them in two forms, hom hard and soft rub-` ber.
That shown in Fig. I, I provide with two small anges d d, at the upper end, to receive the teeth of the'upper jaw on cushions al a. Upon the other end, I form two flanges fi i, of hard rubber, which serve to keepthe tongue and cheek away while filling lower teeth, thus preventing the saliva from being pressed up into the cavity while being lledf which destroys the adhe-- siveness of`the gold.
The other fornuas shown in Fig. II, I provide with small anges did d d, at'each end. The object of these anges is to obviate the danger arising from displacement so liable tohappen. Also, the soft-rubbercnshions a a, to receive the upper and lower jaw-teeth, giving an easy yielding surface to the bite of the teeth. This soft rubber extends up into the flanges rl (l d d, which, in vulcanizing, unites 'with the body of the braces B and O, forming a-soft and yielding surface for the teeth and jaws.
lThe manner of using my invention: Place the jawbracc between the jaws, letting the teethrest upon'the cushions a. a c c, with the anges (l d d d embracing the buccal and lingual surface of the teeth.
For all operations upon the`mouth, this brace possesses superior advantages, furnishing a safe cushion for the bite of the teeth, and the flanges secure it in place, obviating the danger of swallowing or choking,
as occurs where the, cork is used.
What I claim as my invention, and desire to secure by Letters Patent, .isi 1. The dental jaw-brace, as shown in Figs. I and II, for use in the extractingand filling of teeth; B and O showing body of brace made of hardrubber, the
cushions c a a a made of soft rubber, which extend up into the anges l cl d d d l and it, when these several partsare constructed and specified asl above described. .Y
2. Any dental jaw-brace, regarding shape, when these materials are used; B and G, the body of brace, made of hard rubber; a a, the soft-rubber cushions, and then vulcanized, when these several parts are constructed for the purposes as are herein set forth.
