FELT-CUTTING TOOL.

Applicatoin filed December This invention relates to mechanics hand tools of the character known as s'hears,snips or cutters, and it has for its principal object such a tool which will cut sheet felt and similar fibrous material, particularly in the cutting out of washers and gaskets as so largely used in automobile work.

With an idea of giving a clear impression of just what the tool accomplishes so that its following detailed description will be easily understood, it should be noted that in order to cut a washer from a very thick piece of felt, a pair of scissors cannot be used for if the felt is hard, they will not cut at all, and there is no way by which they can be brought into action'for cutting out the hole in the washer especially if the hole is but an inch or two in diameter.

There are revolving cutters which will do the work on large felt washers but they are expensive, not readily portable, as they require to be used on a bench, andarenotat all adapted to the cutting of other forms than round.

Consequently the mechanic always must resort to the use of a hard wood block with a chisel and hammer, or a sharp knife to ardously cut out the desired forms.

However, with the simple tool shown in the accompanying drawings, awasher of any size, or any other shape, may be quickly and easily cut from the toughest felt, leather, rubber or other sheet material and by anyone with practically no experience.

In the drawings 1- Figure 1 is a perspective view of the complete tool drawn substantially full size with the lever as though depressed by an opera-- tor and the blade forced downward through the anvil.

Figures 2 and 3 are detached front and side views of the plunger knife, and

Figure a is an enlarged front sectional view of the blade and anvil showing a modified sharpening of the cutting edge of the blade.

The device as shown in the drawings takes the form of a plier or punch like hand tool having a body 1 with a U-shaped handle 2 through an opening formed in the body and abnormally hard cut.

is positioned with'its blade directed toward the anvil so as to snugly enter a slot 7 therein when the plunger is moved in a direction toward the anvil. I To operate the plunger, a lever handle 8 15 provided which passes through a slot in the end of the plunger being pivoted to it at 9 andextending forward of the plunger and pivoted at 10 to a link 11 in turn pivoted atv 12 to a horn 13 extending forwardly from the body. a i Surrounding the plunger is a spiral compression spring 14- reacting between the top of the body 1 and a pin 15 projecting from the plunger and which spring serves to n'ormally hold the plunger and lever raised to the position indicated by the dotted lines so that the point only of the blade will project from the body. I The space between'the upper and lower portions of the U handle is'large enough to receive the fingers of the operators hand and in addition the thickest sheet of material which it is desired to cut, so that a large cutting on smaller pieces of material, the

lingers of the operating hand may grip the under run of the -U handle with the thumb portion of the hand placed over the lever 8 for forcing the blade through the material into the anvil and thereby serve also to steady the anvil against deflection due to an The slot 7 in the anvil ispreferably somewhat longer than the width of the blade, a snug lit for the thickness of the blade and the cutting edge of the blade is formed at an I outwardly slanting angle to receive the material'and with a point at its inner edge.

The cutting edge in relation to the anvil edges may vary somewhat with different usage, and Figures 2 and 3 show a single shear blade which would have a cutting ac- 1G0 tion against one side of the anvil slot, whereas Figure .irSllOYS a square edge blade 5 having a shearing action against both edges of the anvil. i V a The rearwardly slanting blade with point as shown in Figure 1 at 5' is of great importance for the point is used to locate the beginning of the out and the material is fed with the left hand into the tool against the slanted edge while'the plunger is operated like a punch by the right hand gripping the handle 2 and lever 8 as described.

Thus, a out can be started at any point within a sheet of material, such as for instance, the cutting out of a hole in a felt Washer, and with the greatest facility the cut may be given any required curve by guiding the material in the desired direction against th blade while working the reciprocating blade up and down through it, in fact with the leverage of the tool shown, felt a quarter 01"? an inch or more in thicl-: ness can be handled about as easily as paper with an ordinary pair of scissors.

The lever 8 extending through the s"-""ted portion of the plunger prev .its same from turning out of alignment with the slot in the anviland is a simple way of overcoming any necessity of splining the plunger to thebody, the this may also be resorted to if desired.
