UNITED STATES PATENT OFFICE.
HUGO AIDERER, OF EAST ORANGE, NEW JERSEY, ASSIGNOR TO J. F. JELENKO & 00., OF NEW YORK, N. Y., A FIRM COMPOSED OF JESSE F. JELENKO AND HUGO ADERER.
LINGUAL BAR.
7 Specification of Letters latent.
Patented Mar. 15, 1921.
Application filed January 17, 1920. Serial No. 352,032.
To all whom it may concern:
Be it known that I, HUGO ADERER, a citizen of the United States of America, residing at 82 South Parkway, East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Lingual Bars, of which the followingis a specification.
My invention relates to improved lingual bars such as are used in the art of dentistry.
Among the objects of my invention is the production of a bar which will economize space, will be strong and rigid when in use, and which may be easily manipulated without injury to the structure of the bar.
I attain these and other objects by the structure illustrated in the accompanying drawings, in which Figure 1 is a perspective view of my bar having one end inserted in the usual rubber plate having teeth attached thereto, said plate being shown in section;
Fig. 2 is a vertical section on the lines 2-2 of Fig. 1;
Fig. 3 is a bottom plan view; and
Fig. 4 is a side elevation of one end and a part of the body portion of the bar.
Bars made according to my invention may be made of any suitable material such as cased or solid gold metal. The body portion 1 as illustrated is elliptical in crosssection, although it may be circular or any other desired shape, and is bent generally to conform to the shape of the human jaw. The ends 2 are duplicates having the upper part 3 thereof corrugated or cri-mped and the lower part 4: flat. In Fig. '1 is illustrated a method of using the bar by show ing one end inserted in the ordinary rubber plate 5 which has teeth (3 attached thereto.
Instead of corrugating the entire surface of the ends of the bar inserted in the rubber, as has been previously done, I have corrugated the upper part only, enabling me to obtain the strength of an uncorrugated bar and to have a portion of the bar corrugated in order to securely attach the rubber. If it is necessary to change the shape of the bar, this may be done by applying the pliers to the uncorrugated ends of the bar. Having a part only of the ends corrugated and theother part fiat, results in the advantage of taking up less space on the lower part of the rubber where the bar is vulcanized on.
Having described my invention, what I claim is:
1. A lingual bar having corrugations on a part thereof, said corrugations extending from one edge only of said bar and terminating short of the opposite edge whereby adjacent flat and corrugated surfaces are provided.
2. A lingual bar comprising a body portion and ends, a part of the surface of each of said ends being corrugated throughout the entire length of said ends, and a part of the surface of each of said ends being smooth throughout the entire length of said ends, said corrugations extending from an edge of said bar toward the other edge thereof.
In testimony whereof I affix my signature.
HUGO ADERER.
