: TO aZZ whom it may concern:

Be it known that I, ELMnn Li- Sorro- MAGHER, a citizen of the United States, re-

siding at Southbridge, in the county of \Vorcester and State of Massachusetts, have invented certain new and useful Improvements in Ophthalmic Temples and Processes for Making the Same, of which the following is a specification. V

The present invention relates to an ophthalmic temple and to the process of producing the same and has particular reference to means for producing such temples more rapidly and more economically than has 1 heretofore been done.

An important object of the invention is to provide means whereby a plurality of ophthalmic temple blanks can be stamped out in one operation in the form of a master blank, after which the master blank can be separated or divided into individual blanks from which the finished product is obtained.

Another very important object of the invention is to provide means whereby a temple. can be formed from cellulose composition material in such a manner that the amount of material wasted or scrapped will be reduced to a minimum.

A still further object of the invention is to form a master blank from which individual or single blanks can be cut to form cellulose composition material ophthalmic temples.

Other objects and advantages will become apparent during the course of the following description.

In the drawings, wherein like numerals are employed to designate like parts 40 throughout the same:

Figure 1 is a top plan View of the master blank formed in accordance with the present invention.

Figure 2 is a side elevation thereof.

Figure 3 shows a single blank after it has been separated from the master blank.

Figure 4 is a side elevation of the same after the smoothing operation.

Figure 5 is an end view'thereof. Figure 6 is a section on line 6-6 in Fig ure 4.

Figure 7 .The staggered projections 11 correspond to Figure 8 is a top plan th s g In t manufacture ofc'ellulo tion material ophthalmic temples andespe? ciallyfthe' type of temples known in theart as skull fit' temples 'agreat amount 'of"waste material has been had because of the shape of the blank from which such temples are formed. The cellulose composition material from which these temples are formed is expensive and due to the peculiar qualities thereof, scrap stock cannot be re-worked and formed into new stockwhich is'of first class quality. Furthermore, the resale value of the scrap stock is a very small fraction of j the original cost price so, that in order to produce a first class quality article from high class material it is essential that the amount of waste material be reduced to a minimum.

In addition to the cost of the materials used, the methods used in the prior art have been expensive due to the amount of time and labor required tostamp individual tem ple blanks from the sheet stock. V

In the present invention, I have so arranged the stamping operations that the amount of material wasted is greatly reduced and the time and labor required is only a portion of the time and labor required in the old process.

In the drawings, wherein for. the purposes of illustration is shown the preferred em bodiment of'the invention, the numeral 10 designates what I call a master blank. It

will be seen that the master blank 10 has at each end the staggered projections 11.

the end 12 of the'blank shown in Figure 3. .The master blank is stamped from sheet stock and is divided along the lines 13 clearly shown in Figure 1, so as to produce a plurality of single blanks 14. It is necessary to stagger the position of the projections 11 so that the blanks 14 can be separated from the master blank without any waste between the individual blanks. After the blanks are formed as in Figure 3 they are milled or otherwise reduced, as in dotted lines 15. After the milling has been done the blank can be shaped and polished into the form as designated by the numeral 16 in Figure t. The' operations from here on correspond to thepriorart way and include putting the blank 16 into a suitable form or mold to bend the same into the shape of the finished temple 17 as shown in Figures 7 the master blank 10,.ther is no Waste stockbetween the same and due to the fact that a plurality of blanks'are stamped in a single operation, a saving in time and labor is had.

It is to be understood that the form of the invention herewith shown and described is to be taken as the preferred embodiment of the same and that various changes in the shape, size and arrangement of parts may be resorted to Without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention,

shaping and polishing the single blanks and then bending them into form.

2. A master blank of the character described having staggered projections at its ends, the said master blank being adapted to be separated into individual blanks'trom which ophthalmic mounting temples can be formed.
