SIPEGIFIGATION forming part of Letters Patent N0. 755,440, dated March 22, 1904.

Application filed November 27, 1903.. eria1N 182,940. (No model.)

To all whom it may concern:

Be it known that I, HERMAN E. BONSOHUR, a

citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Pliers, of which the following is a specification. I

My invention relates to certain improvements in pliers used especially by Opticians to retain the nose-guard of eyeglasses to the post While being secured thereto.

The object of my invention is to so form the jaws of a pair of pliers that they will properly hold the nose-guard or bow to the post while it is being secured to the post without placing any strain upon the lens or other portion of the eyeglass. This object I attain in the following manner, reference being had to the accompanying drawings, in which Figure 1 is a perspective View of a pair of pliers, illustrating my invention. Fig. 2 is a longitudinal sectional view of a portion of the pliers, showing an eyeglass post and guard in position. Fig. 3 is a section on the line 3 3, Fig. 2. Fig. 4: is a plan View of Fig. 2. Fig. 5 is a View showing the opening when the pliers are to be used with a guard that does not extend beyond both sides of the post. Fig. 6 is a view of a modification of the invention. Fig. 7 is a View showing one jaw of the pliers recessed to receive a flange on the post of an eyeglass. Fig. 8 is a View of a modification of the jaw shown in Fig. 7, and Figs. 9, 10, and 11 are views of further modifications.

A A are the two members of the pliers, pivoted in the ordinary manner and each having a suitable handle.

a and 6 are the jaws of the pliers. The end of the jaw a has two prongs ca, forming a fork, while there is a squared opening 6 in the jaw b.

In applying a nose-guard to the post of an eyeglass it is a difiicult matter to properly hold the post while the guard is being secured thereto. As shown in Fig. 3, the post (Z is attached to the lens D by a pin or other means and has flanges d, which form a socket for the reception of the arm 6 of the guard E, which is secured to the post by a screw 0. Usually the lens is grasped and the guard is balanced on the post while the screw is applied; but in tightening up the screw oftentimes through carelessness the lens is cracked at the post, and this crack is not noticed in many instances until the eyeglasses are worn for a time, and again the lenses crack so badly that they break and have to be discarded.

By my improved pliers I am enabled to grasp the post directly under the, socket, as indicated in Fig. 2, by means of the forked jaw, the arms a. of the fork extending on each side of the body portion of the post, while the squared opening 6 in the other jaw, Z), allows the flanges of the post to extend through the jaw, so that when the arm 6 of the guard E is placed in the socket the side members of the upper jaw will rest directly on the arm of the guard and hold it firmly in the socket while the screw is being applied. Considerable pressure can be used in turning the screw, as there is no liability of the lens being cracked, all pressure being taken off the lens.

In some instances I may make the recesses ff in the innerportions of the forked members a of the jaw a, as indicated in Fig. 7 so that in the event of the post having an annular rib directly under the socket the jaw will fit snugly against the base of the socket, or in some instances, where the post proper is soldered to the socket, the recesses will accommodate the solder should any extend beyond the edge of the post.

In some instances instead of making the recesses entirely through the arms, as shown in Fig. 7, the recesses may be made as shown in Fig 8, in which case only the face of the jaw is recessed for the reception of the flange.

I prefer to make the internal projections ii on the portions 6 of the pliers, as shown in Figs. 1 and 5, so that thejaw twill be sure to press upon the arm of the guard on each side of the screw, as indicated in Fig. 5, and this is especially necessary when the ordinary guard is used, which is not provided with a head such as that shown in Fig. 4-, but does not extend beyond the post.

VVhileI have shown projections 2' on each of the side members 72 one side member only may have a projection, if desired; but Iprefer to place them on both members, so that the tool can be used either right or left.

In some instances the end bar 6 may be dispensed with, as shown in Fig. 6, making two forked members; but the forked members in this instance must have one or both of the internal projections 71.

I may, if necessary, bevel the corners of one of the jaws of the pliers by bending, as shown in Figs. 9 and 10, so that the corners will not interfere when the pliers are used to attach a nose-guard which'has already been bent and adjusted to the nose of the wearer, as

the clamping of the pliers may in some instances alter the adjustment; but by bending the jaw at the corners the pliers will not interfere with the nose-guard. Instead of bending the jaw Imay bevel it by cutting away the corners, as shown in Fig. 11.

I claim asmy invention- 1. The combination in a pair of pliers, of two jaws, one jaw being forked to engage the post of an eyeglass, the other jaw having an opening through which the post of the eyeglass extends, the side members of said jaw being shaped to engage the guard of the eyeglass, while allowing the flanges of the post to be free so as to hold the guard securely to the post while it is being attached thereto, substantially as described.

2. The combination in a pair of pliers, of two jaws, one jaw being forked to engage the post of an eyeglass and the other jaw having a squared opening throughwhich the post eX- tends and which will clamp the guard to the post while it is being attached thereto, substantially as described.

3. The combination in a pair of pliers, of two jaws, one jaw being forked to engage the post and having recesses in the forked portions so that the body of the jaw will press against the bottom of the socket of the post, and the other jaw having an opening through which the post extends so that it will clamp the guard to the post while it is being secured thereto, substantially as described.

4. The combination in a pair of pliers, of two jaws, one jaw being forked to engage the post and the other jaw having an opening through which the post extends and having an internal projection on one side member to engage a guard mounted in the socket of the post, substantially as described.

5. The combination in a pair of pliers, of two jaws, one jaw being forked to engage the post and the other jaw having an opening through which the post extends, and having an internal projection on each side member to engage a guard mounted in the socket of the post, substantially as described.

6. The combination in a pair of pliers, of two jaws, one jaw forked and the other jaw having an opening to receive the flanges of the post of an eyeglass, the bearing-face of the jaw being beveled at the corners, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
