PROCESS IN FORMING METAL BACKS FOR ARTIHCIAL TEETH.
APPLICATION HLED APR. 7, I9l9 1,322,424. Patented Nov. 18, 1919;
ERNEST GARDEN, 013 LOS ANGELES, CALIFORNIA.
PROCESS IN FORMING METAL BACKS FOR ARTIFICIAL TEETH.
Specification of Letters Patent.
Patented Nov. 18, 1919.
Application filed April 7, 1919. Serial No, 287,982.
To all whom it may concern:
Be it known that I, ERNEST GARDEN, a citizen of the United States, residing at the city of Los Angeles, county of Los Angeles, State of California, have invented a new and useful Process in Forming Metal Backs for Artificial Teeth, of which the following is a specification.
Heretofore in the production of metal backs for artificial teeth it has been cus tomary to form such backs in detached or separate pieces which takes considerable time and as the backs are small the process is tedious.
It is the object of my invention to form such backs in strip containing a number of backs each of which can be detached for use when desired, thereby shortening the time in which a number of backs can be formed, and making the same more convenient in handling than if detached backs are used.
In the drawings forming a part of this application Figure 1 shows a portion of a strip of backs formed according to my process. Fig. 2 is an end view of the strip. Fig. 3 shows a slight modification.
In my process I take a piece of suitable metal of a length to make a convenient strip of backs and by means of suitable rolls, not shown, I roll the strip to the shape desired for backs and webs of artificial teeth. In the drawings I have shown this shape as a backing plate 5 on one side of which is a central web 6 which terminates in a rounded head 7. While I have shown the head of the web as round it will be understood that it may be of any other desired configuration to conform to and fit in the groove left in the back of the porcelain tooth front when it is manufactured. After the strip is thus formed I cut out portions of the web as shown in Figs. 1 and 3 and partially sever the back plate as shown by grooves 8 by means of suitable mechanism, not shown, so that the operator can readily break the plate at these grooves and thereby secure a detached back for each porcelain front as needed. In some cases these grooves are close to the web as shown in Fig. 1 or midway between them as shown in Fig. 2 depending on whether it is desired to have only the ridge lap or the bite backed or to have both backed.
By this process I am able to form metal hacks for artificial teeth more expeditiously than when forming each back singly. While I prefer to form the strips for the backs by the use of rolls any other mechanism may be used which will form the strip of metal into form suitable for artificial teeth backs.
Having described my invention, I claim:
1. The herein described process for forming metal backs for artificial teeth which consists of forming a piece of metal into a back strip having a central web on one side thereof, said web terminating in a. head, and then removing specified portions of said web from saidback strip and partially severing said back strip at said portions where such web is removed.
2. As a new article of manufacture an artificial tooth backing comprising a strip of metal formed into a backing strip partially severed by a plurality of transverse cuts, said strip having short central webs 011 one side of said strip terminating in heads, there being a short web at each transverse out.
In witness that I claim the foregoing I have hereunto subscribed my name this 31st day of March, 1919.
ERNEST GARDEN.
