' Specification of Iletters Patent. Patnted Sept, 14, 192() Application filed October 7, 1919. Serial No. 328,958.

To all whom it may com-(rm:

Be it known that 1, Lotus R. SMrrn, a

citizen of the United States, residing at Lomita, in the county of Los Angeles and State of California, have invented new and useful Improvements in Finishing and Burnishing Pliers, of which the following is a specification.

This invention relates to a plier for finishing and burnishing the rough ends of 5 pins, bolts, screws, and the like. It is especially adaptable for use by Opticians.

In the assembling of eye glasses of the rimless type, the bridge is fastened to the lenses by screws which extend through the lenses and through sockets on the bridge which embrace the lenses. After a screw has been inserted and tightened, the projecting end is cut ofi. It is difficult to polish the rough end, and it is therefore common practice to leave the samein rough condition, thereby marring the finish of the structure collecting dirt and otherwise being detrimental. With bridges having spring members to grip the nose. other screws are used the ends of which are cut off and should be finished and burnished.

It is the primary object of my invention to provide pliers of simple, durable construction, whereby a screw or the like may be gripped between the jaws, such pliers having means to finish and burnish the end of the screw.

This object will be more fully understood as will also other objects and corresponding accomplishments of my invention from the following detailed. description of a preferred embodiment thereof. For the purpose of this description reference is had to the accompanying drawing, in which:

Figure 1 is a side elevation of my improved pliers; Fig. 2 is a plan View showing the pliers applied to a screw holding a lens to a bridge; Fig. 3 is a fragmentary view taken on the line 3--3 of Fig. 2; Fig. 4 is an enlarged view of the finishing and burnishing element; and Fig. 5 is a bottom view of the burnishing element shown in Fig. 4-. Referring more particularly to the drawing, 6 indicates a handle of the pliers, and 7 a jaw secured thereto. Adjacent the nose of the pliers is a concave recess Sadapted to receive the head of a screw. This recess merely serves as a pocket in which a screw head may be disposed to hold it in position while the screw is being operated upon. The other handle of the pliers is indicated by 9 and is formed with a jaw 10 of special construction. Jaw 10 is formed with a bearing'block 11 at the end thereof, in which is journaled a finishing and burnishing element.

The finishing and burnishing element comprises a shaft 12 having a head 13, which tapers and is formed with a concavity 14; at the end. Extending across the concavity are grooves 15 which serve to cut and assist in the finishing. Shaft 12 is journaled in the bearing block 11 so that the head 13 registers with the recess 8. A handle 16 is secured to the end of the shaft 12 for turning the latter. Interposed between the handle and the bearing blockis a helical spring 17, which serves to hold the head 13 against the jaw.

Infinishing the bridge holding screw of an eye glass, the screw 1.8 is gripped between the jaws of the pliers, the head being inserted in recess 8, and the unfinished cut I end thereof resting in the concavity 1 10f the finishing element. The handle 16 is now turned until the end of the screw has been finished and burnished. In order to make the pliers convenient for operation, the usual leaf spring 19 is inserted be tween the handles, tending to hold the jaws in open position.

lVhat I claim is:

1. A finishing and burnishing pliers comprising a pair of jaws, and a finishing and burnishing element mounted on one of said jaws in the opening therebetween.

2. A finishing and burnishing pliers comprising a pair of jaws, and a finishing and burnishing element journaled in one of the jaws in the opening therebetween.

3. A finishing and burnishing pliers comprising a pair of jaws and a rotatable finishing and burnishing head mounted on the inside of one of said jaws with its axis transverse to the longitudinal axis of said jaw.

4. A finishing and burnishing pliers comprising a pair of jaws, one of said aws having a'bearing extending transverse thereto at its nose, and a shaft journaled in said bearing having a burnishing end finishing head located on the inside of said jaw.

5. A finishing and burnishing pliers comprising & pair of jaws one of said jaws having a bearing extending transverse thereto at its nose, and shaft journaled in said bearing having a burnishing and finishing head located on the inside of said jaw, the

other of said jaws being provided with a pocket in registration with said head ior 10 receiving the head of the article to be operated upon.

In Witness thatl claim the foregoing I have hereunto subscribed my name this 29th day ofsepteniber, 1919.

LOUIS R. SMITH.
