GASKET AND WASHER CUTTER.

Specification of Letters Patent.

Patented Julyt, 1916.

Application filed May s, 1916. Sean No. 96,198.

To all whom it may concern:

Be it known that 1, CHARLES Born, a citizen of the United States, residing at New Philadelphia, in the county of Tuscarawas and State of Ohio, have invented certain new and useful Improvements in Gasket and Washer Cutters; and I do declare the following to be a full, clear, and exact description of the invention, such as will en able others skilled in the artto which it appertains to make and use the same. 7

The present invention relates to a new'and very simple but useful tool for the cutting of washers or gaskets from leather and other materials ordinarily employed therefor, upon carriages, wagons, for pump packing, and many other various purposes too numerous to herein enumerate, but which are well known to all conversant with mechanics.

The primary object of the invention is to provide a hand tool of this character which is adjustable to cut washers or gaskets of sizes varying within certain limits.

Another object of the invention is to provide a washer cutter having an improved means forholding the material from which the washer is to be cut in operative position.

A still further object is to provide a clevice of this character which will be simple, strong, durable and inexpensive in construction, efficient and reliable in operation, and well adapted to the purpose for which it is designed.

With these and other objects in view, the invention consists of certain novel features of construction, and the combination and ar rangement of parts as will be hereinafter fully described and claimed.

In the accompanying drawings :Figure 1 is an elevation of one side of a device constructed in accordance with this invention; Fig. 2 is a bottom plan view of the same; Figs. 3 and 4: are vertical transverse sectional views taken on the planes of the lines 3-3 and l t of Fig. 1; Fig. 5 is a vertical sectional view showing the construction of the lower end of the center pin and the clamping disk applied thereto; and Fig. 6 is a perspective view of the horizontal beam separated from the other parts.

Similar reference characters designate like parts throughout the several views. In the embodiment illustrated, the reference numeral 1 represents a horizontal beam,

here shown in the form of a bar provided with downwardly extending flanges 2 at its opposite edges to provide a channel 3 in the lower side thereof. This beam or bar 1 is provided with an opening a midway of the ends thereof, and arranged oneach side of the opening a and extending longitudinally of the bar are slots 5. The upper side of one of the flanges 2 is graduated in inches and fractions thereof to provide a scale, the purpose of which will be obvious, while the outer side of the other flange 2 is graduated in opposite directions from a point opposite the opening 4 thereof. This latter set of graduations or scale is designed for the purpose of aiding in setting the cutters to be hereinafter described, to out the washer or gasket the desired size.

Secured in any suitable manner, but preferably' by rivets 6 are the inwardly bent ends 7 of a longitudinally curved or arched handle member 8. The edges of this handle member 8 may, if desired, be curved downwardly to provide means for preventing injury to the hand of the operator, as will be obvious. Secured to the intermediate portion of the handle member 8 in any suitable manner are the ofiset ends 9 of a plate 10, the latter being spaced a short distance below or inwardly from the inner or lower side of said handle member and provided with an opening 11 arranged in alinement with the aforesaid opening 4:, to provide a suitable guide.

Slidably mounted in the alined openings 4 and 11, and extending considerably below the loweredge of the bar 1 is an upright center pin 12, having a stop 13 of any suitable construction arranged thereon above the bar 1. Surrounding the pin 12 and disposed between the stop 13 and the plate 10 is a coiled spring 1 1, which as will be readily understood, normally holds said pin 12 in its protracted position, but allows the same to be retracted when pressed uponat its lower end.

The lower end of the pin 12 is reduced in diameter as at 15 to provide a shoulder 16, and is pointed in order that it may be readily inserted into the material from which the gasket or washer is to be cut. This reduced portion 15 is adapted to receive a clamping disk 17 having an opening 18 therein, said disk 17 resting against the shoulder 16 and securely holding the work to be operated upon in position. It is to be understood that this disk 17 may be substituted or replaced by other disks of suitable sizes according to the size of the washer to be cut.

Slidable in the channel 3 of the bar 1 between the flanges 2 of the same is a pair of substantially rectangular-shaped plates or blocks 19, one of the ends of which is'bent laterally downwardly at right angles and provided with cutting edges to form cutters 20. These blocks 19 are provided with apertures 21 through which suitable clamping or fastening elements or bolts 22 are extended for engagement with nut members 23. By this arrangement it may be seen that the out ters 20 may be adjusted toward and away from the center pin any desired distance.

In using the device, one of the cutters 20 is adjusted so that it will cut the inside circle or edge of the washer, while the other cutter is adjusted at a different distance from the center pin so that it will cut the outside edge of the washer. The clamping disk is then inserted upon the reduced pointed end of the center pin and the latter is inserted in the material from which the washer is to be out. By grasping the handle and rotating the device around the center pin and under pressure, the cutters will cut into the material and will cut the washer or gasket from the same with but one operation of the device.

From the foregoing description, taken in connection with the accompanying drawings, the operation and construction of the device will be readily understood without a more extended explanation.

As various changes in form, proportion, and in the minor details of construction may be resorted to without departing from the spirit of this invention I do not wish to be limited to the construction herein shown and described other than as set forth in the appended claims.

I claim 1. A device of the class described comprising a horizontal beam, a spring-protracted center pin carried thereby having its lower end pointed and reduced in diameter to form a shoulder against which a suitable sized clamping disk is adapted to bear, and cutters mounted on said beam.

2. A device of the class described comprising a horizontal beam, an arched handle member connected at its ends to said beam, a guide carried by said handle member, a spring-protracted center pin having one end mounted in said guide and its other end extended through said beam, and cutters adj ustably mounted on the latter.

3. A device of the class described comprising a horizontal channeled bar having an opening therein midway of the ends thereof and longitudinal slots on each side of said opening, an arched handle member connected at its ends to the ends of said bar, a plate fixed to the inner side of the intermediate portion of said member and spaced therefrom, said plate having an opening therein in alinement with the opening in said bar, a

center pin slidably mounted in said alined opening, a stop on said pin, a coiled spring surrounding said pin and disposed between said stop and said plate for normally holding said pin protracted, blocks slidable in the channel in said bar and having one of their ends bent laterally and provided with cutting edges, and clamping elements extended through said slots and engaged with said blocks for locking the same in their adjusted positions.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
