Dec. 24, 1929. M1 HARTER 1,740,591


My invention relates to pliers, and more particularly to valve pliers adapted for use on automobiles in handling horse shoe washers, spring washers, valve pins, cotter pins, especially when in inaccessible places, in putting in pig tail generator brushes, and the like.

To the above end, generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claim.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a plan view of the improved pliers holding a valve pin;

Fig. 2 is a side elevation of the same, with some parts broken away and sectioned;

Fig. 3 is a fragmentary perspective View of the free end portions of the jaws of the pliers holding a horse shoe washer;

Fig. l is a view in transverse section taken on the line ll of Fig. 2; and

Fig. 5 is a view of one of the blanks from which the handleequipped jaws of the pliers are formed.

The improved pliers comprises only three parts, to wit: a pair of jaws 6, each of which has an integral handle 7 and a pivot 8 connecting said j aws. Each jaw 6 and its handle 7 is pressed from a single sheet metal blank 9, as shown in Fig. 5. Each blank 9 is provided with a pair of transversely spaced holes 10 for the pivot 8, and between these holes there is formed a longitudinal slot 11. The jaw end of the blank 9 is folded to form a channel, and the handle end thereof is folded to form a tubular structure. The sides of one of the jaws 6, at its slot 11, are spread to permit the other jaw 8 to be inserted therethrough and align the holes 10 to receive the pivot 8, as best shown in Fig. 1.

It will be noted that the sides of the channel jaws 6 are turned toward each other, and the outer ends thereof are adapted to hold a valve pin or other objects, including cotter pins. With an object thus held, it is possible to handle the same in inaccessible places, thus saving a large amount of time.

Serial No. 642,504.

Inward of the outer ends of the jaws 6, the same are outwardly bulged to form pockets 12 adapted to hold a horse shoe washer 1 as shown in Fig. 2. With a washer thus held it is an extremely easy matter to apply the same to a valve stem while the spring and spring retainer are held depressed, or in removing the same therefrom. In addition to horse shoe washers, spring washers or similar articles may be very easily handled.

In handling cotter pins, the heads thereof will beheld in the pockets 12 so that they cannot move endwise when using force to insert the rotter pins into holes, or when pulling the same.

The blank 9 is transversely folded throughout its entire length in the same direction to form the channel jaws 6 and hollow handles 7, thus brin ing the seams in said handles at the outer faces thereof. The inner faces of the hollow handles 7 are made transversely concave to improve the appearance thereof.

The above described invention, while extremely simple and of comparatively small cost to manufacture, has been put into extensive commercial use and proven highly efficient for the purposes had in View.

Vhat- I claim is:

A pair of pliers comprising a pair of duplicate members, each of which is formed from a single sheet of metal folded to form a long channel-shaped jaw and a hollow handle and having a longitudinally extended slot between said jaw and hollow handle, the sides of one of said members at its slot being laterally spaced and the other of said members extending therebetween, and a pin extending through aligned holes in the sides of said members and pivotally connecting the same, the open sides of the channel-shaped jaws being turned toward each other.

In testimony whereof I affix my signature.
