BENDING AND SHAPING PLIERS.

UNITED STATES PATENT OFFICE JOHN W. BOWKER, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO GLOBE OPTICAL COMPANY, OF BOSTON, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS.
BENDING AND SHAPING PLIERS.
Specification of Letters Patent.
Patented Nov. 21, 1905.
To all whom it may concern.-
Be it known that I, JOHN W. BOWKER, acitizen of the United States, residing in Boston, in the county of Suffolk and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Bending and Shaping Pliers, of which the following is a specification, reference being bad to the accompanying drawings.
This invention relates to improvements in pliers, and particularly to improvements in pliers used in the manufacture of optical goods.
The object of my improvement is to provide pliers which in adjusting the straps used with frameless glasses shall maintain the straps parallel.
It has long been desired in the opticians art to obtain a pliers which would enable not only the expert but also the ordinary workman to shape and bend the lens-straps of rimless glasses, so that the lenses may be inserted without danger of breakage. Heretofore, so far as known to me, the only pliers in general use for the purpose of bending the straps of rimless glasses were the ordinary snipe-nose pliers, which even in the hands of an expert workman failed frequently to give the straps such perfect parallelism as to avoid frequent breakage of the lenses when the latter were put in place. By the pliers hereinafter described this long-felt want is designed to be met.
In the drawings illustrating the principle of my invention and the best mode now known to me of applying that principle, Figure 1 is a side elevation of my new pliers. Fig. Qshows the position of the pliers in the process of widening the space between the straps. Fig. 3 illustrates the position of the pliers in narrowing the space between thestraps, and Fig. 4 represents the position of the pliers in changing the glass-bearing part of the strap to accommodate a lens in which the hole is drilled too near the edge.
The tWo cooperating members a and t are pivotally secured together at 0 and are formed with jaws d and 6, respectively. The opposed working faces f and g, respectively, of
is formed with a curved tip t', which overlaps the rounded tip it, whereby these extremities are adapted to engage one within and the other without the shoulder of a lens-strap for rimless glasses and to adjust the members thereof toward and from each other while maintaining them in parallelism.
In the drawings are illustrated three distinct uses to which my pliers may be put in the manipulation of straps used in the manufacture of frameless eyeglasses.
In Fig. 2 the straps m and n are to be sep arated from each other and yet maintained parallel. The extremity it is placed inside the shoulder, while the extremity iby reason of its curved form is adapted to fit snugly upon the outside of the shoulder, andby reason of this construction the jaws operate upon the shoulder and permit the widening of the space between the straps m and 12., while maintaining them parallel.
In Fig. 3 the straps are to be brought nearer together and yet retained in parallelism with each other. In this case the curved extremity t is placed inside the shoulder while the straight extremity it rests upon the outside of the strap.
In Fig. 4 is shown the manner of adjusting the strap member 0 to accommodate a lens in which the hole has been drilled too near the edge.
What I claim is 1. Bending and shaping pliers the extremity of one jaw of which is straight and formed with a rounded tip and the extremity of the other jaw of which is formed with a curved tip which overlaps said rounded tip.
2. Bending and shaping pliers the opposed working faces of the jaws of which are straight and parallel; and the extremity of one of said jaws being straight and formed with a rounded tip, and the extremity of the other of said jaws being formed with a curved tip which overlaps said rounded tip; whereby said extremities are adapted to engage one within and the other without the shoulder of a lensstrap and to adjust the members thereof toward and from each other while maintaining them in parallelism.
