FREDERICK r; ronnnnor BROOKLYN, new YonK] PLIERS.

Application filed December 16, 1921." Serial No. 522,340.

To all whom it may concern:

Be it known that I, FREDERICK T. Fem-1L, a citizen of the United States, andresident ofthe city of New York borough of Brooklyn, in the county" of Kings and." State of New York, have invented a new and improvedPliers, of whichthe followingflisa full, clear, and exact description.

My invention relates to pliers, and aims to provide a device ofthis nature particu' larly adaptable for use in connection with optical work. I

It is a well appreciated fact, in connection with spectacles, eye-glasses, etc, that considerable difficulty has been experienced in properly applying the clamping pieces to the lens in such a manner that no play might exist between these elements.

With this in mind, my present invention.

aims to provide pliers, and primarily pliers I which shall be extremely simple in con struction, and by means of. which an optician will becapable of accurately fitting the clamping arms of the nose piece, and other parts of the spectacle to the lens, in such a manner that no play will come into being between these parts.

A further object of this invention is the construction of a device of the character specified, which shall be adaptable for use in connection with the application of the arms of'the frame to virtually any thick ness of lens.

Still further objects of this invention will appear in the annexed specification, taken in connection with the drawings, which latter illustrate one practical embodiment thereof, and in which;

Figure 1 is a side elevation of the forward end of a pliers embodying my. improved construction.

Figure 2 is an edge view thereof.

'Figure 3 is a view similar to Figurel and showing the pliers in use, and

Figure 4 is an edge view "of'one of the details of construction. I

Inthese views it will be seen that thereference numeral 5 indicates the handles of the pliers, which may be .of any desirable construction, and terminate in jaws 6, the latter being pivotally secured together, as at 7, in the usual construction.

Contrary to the conventional construction however, it will be noted that the inner faces of the jaws 6 are recessed as at 8, so that only the outer ends of these members will co-operate with each. other, the bodies of the same providing a space for a purpose hereinafter specified.

1% set screw 9 extends through ascrew threaded opening in one of the jaws 6, and co-operates with the second. of these jaws. and itwillbe noted that a pin 10 is also associated with one of the'jaws, whichpin serves to movably mount an arcuate wedgeshaped'element 11,preferably formed with a flanged outer edge 12.

In use this element is swung to the position shown in Figure 1, and in full lines in Figure 2. The lens to be worked upon is then inserted between the outer ends of the jaws 6, and these latter members are'actuated by means of the handles 5 to engage opposite faces of the lenses.

The set screw 9 is now actuated until the outer end of the same en 'a es the inner face of the jaw with which it co-operates, thus preventing the working parts of the jaws moving closer together than the thickness of the lens which has'just been gaged.

As has been indicatedin Figure 3. the element 11 now has applied to it the member 13 which is to be affixed to the lens, and this element carrying-the member is now swung to a position at which the outer ends of the jawfmay co-operate with the same. A pres sure applied to the handles 5w1ll now result in the legs of the member 13 being bent in-' wardlyto a distance corresponding exactly to the distance of the lens. -However,incident to the flange 12 which extends beyond the outer edges of the jaws 6, the base portions ofthe legs of the member 13 will be bowed adjacent this point, thus strengthening the entire construction. Further, it will be found that upon applying the member 13" to the lens with which it is to be associated,

that the'same willfit accurately and snugly against the opposite faces of thelens in such a manner as to bevirtua-lly immovable with respect to the same. Upon applying a conventional screw provided forthis purpose it will be found that no fear may be felt for any play between these parts coming into being.

Thus 1 have constructed pliers by means of which all of the objects set forth in the preamble of this specification have been ac* complished, and it will further beimderstood that numerous modifications of structime might readily be resorted to Without in iihe least depmting fi ein the spirit 0f my i mnt mn which I claim as:
