TWEEZERS.

To all whom it may concern Be it known that I, Monnon ENonLsamN, a citizen of the United States, and a resident of New York, in the county of New .York and State 01" New York, have invented certain new and useful Improvements in Tweezers, of which the following is a specification.

This invention relates to tweezers, and its object is the production of a tweezer with an adjustable and detachable locking device. The tweezer is or such a character that it may be used without operating the locking device.

In the accompanying drawings which exemplify the invention, Eigure 1 is a front view of the improved tweezer with the legs thereof in their open positions, Fig. 2 is a View similar to Fig. 1 with the legs of the tweezer in their closed positions, Fig. 3 represents a top View of Fig. 2, Fig. 4- shows a bottom plan View of Fig. 2, Fig. 5 is a View similar to Fig. 1 with the locking device detached, Fig. 6 shows a side View of a sliding locking bar and Fig. 7 is a left hand end View of Fig. 6.

The tweezer is shown with the legs 10 and 11. At the outer end of leg 10 is formed the serrated gripping point 12 and adjacent to its other end is formed the guide opening 13. A. guide pin 14 extends from the outer surface of the leg 10 adjacent to its opening 13. The leg 11 has formed at its outer end the serrated gripping point and adjacent to its other end is formed the guide opening 21, while a serrated surface 22 is formed on the outer face of said leg 11. A detachable sliding locking bar 25 with the body thereof somewhat curved has formed therein the guide opening 26 in about its central portion. At one end on the outer surface of said bar 25 is formed the knurled button 27 and from the other end thereof extends the T shaped hook with the depending leg 28 and cross leg 29. The locking bar 25 is carried on the leg 10, the leg 28 extending through the openings 13 and 21, the leg 29 of said hook bearing up against the outer surface of the leg 11, while the guide opening 26 registers with the pin 14. To detach the locking bar 25, it is lifted out out engagement from the pin 14, and then swung. at right angles to the legs of the tweezer, when Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Eatents Specification of Letters Patent.

Application filed November 21, 1910.

Patented May 5, 1914. Serial No. 593,309.

the leg 29 can be lifted out of the guide openings 18 and 21. It will be noted when the tweezer is disengaged from the said locking bar as shown in Fig. 5 that it can be used as an ordinary tweezer.

To use the tweezer with its locking bar it may be supposed to be in its open position as shown in Fig. 1, and when an object is to be gripped by means of the gripping points 12 and 20, the said object is brought between those points and the locking bar pushed up toward said points by means of the knurled button 27. This will cause the T shaped hook to force the legs 10 and 11 toward each other and the said gripping points 12 and 20 will securely hold the said object. To re lease said object the locking bar is moved in an opposite direction when the legs by virtue of their spring tension will release the gripping points from the object. In case the tweezer is to be used without the functions of the locking bar 25, the latter may be retained on the leg 10, or it may be de tached therefrom and used in the ordinary manner.

Having described invention what I desire to secure by Letters Patent and claim is:

1. In a pair of tweezers the combination of a pair of legs each having an opening, a

locking bar slidably supported on one of said legs and a T shaped hook depending, from said locking bar and extending through the openings of both of the legs of the tweezcr.

2. In a pair of tweezers the combination of a pair of le s having guide openings formed therein, a pin extending from one of said legs, a locking bar having a guide opening and supported on the leg of the tweezer having the pin, said pin registering with the guide opening in the locking bar, a T shaped hook depending from the said locking bar and extending through the guide openings of both legs of the tweezer and a button on said locking bar.

Signed at the borough of Manhattan in the county of New York and State of New York this 15th day of November A. D. 1910.
