COMBINED PUNCH, SHEARS, AND SAW -GUMMER.

SPECIFICATION forming part of Letters Patent No. 416,499, dated December 3, 1889.

Application filed September 9, 1889- Serial No. 323,458. (No model.)

of the United States, residing at Sault Ste.

Marie, in the county of Chippewa and State of Michigan, have invented certain new and useful Improvements in a Combined Punch, Shears, and Saw-Gummer, of which the fol-. lowing is a specification, reference being had therein to the accompanying drawings.

This invention relates to a new and useful improvement in a combined saw gummer, shears, and punch; and the invention consists in the peculiar construction whereby the machine may be used for the different purpose of gumniing saws, or, by a change of dies, as a powerful punch or shears, all as more fully hereinafter described, and shown in theaccompanying drawings, in which Figure 1 is a side elevation showing my device as arranged for gumming saws. Fig. 2 is a plan of Fig. 1 with the upper die and lever removed to show the bed-die more plainly. Fig. 3 is a side elevation showing the device mounted as shears, and Fig. 4 is a vertical central section showing the device mounted as a punch.

A is the bed-plate of the device. B are lugs at the ends thereof as means for fastening the bed-plate by screws or belts or otherwise upon a solid foundation. I

O are two parallel guides secured transversely upon the front end of the bed-plate, or made integral therewith, if desired. The inner sides of these guides are undercut to slidingly receive and hold the lower or bed die D. This bed-die is provided upon its inner edge with indentations between the sawteeth, there being a sufficient number of graduated sizes to adaptthe bed-die forgumniing different saws. This bed-die also contains a series of holes F, of graduated sizes,

. to use the beddie for punching holes, as will the guides O O are provided with recesses H opposite each other to receive and hold the stationary knife or shear I when the device is used for shears. Between the upper ends, secured to or formed integral with the bedplate, is pivotally secured a power-lever J, the short arm of which is bifurcated and contains an anti-friction roller, which is adapted to bear at or near the free end of a lever K, which is secured longitudinally between the supports near the rear end of the bed-plate, and the front end of which projects sufficiently to receive suitable dies to act in connection with the stationary dies secured upon the bed-plate.

To make the dies exchangeable, I provide the lever K at its free end with a vertical socket, and the dies I provide with corresponding shanks adapted to enter the sockets and be secured therein by a suitable setscrew L.

The die M for gumining saws is made of suitable shape to punch out the desired indentations between the saw-teeth, and a number of these dies are provided corresponding in size to the indentations in the bed-die.

N is a movable shear,which is also provided with a suitable shank to be secured to the lever K in proper relation to the lower knifeor stationary shear I, and the punch-dies O are properly constructed that when secured to the lever K they may be made to register with the holes F in the lower bed-die.

In practice, the parts being arranged as shown and described, it will be seen that the device is very compact and useful for a variety of purposes, dispensing with the use of separate tools or devices for dilferent work, the adjustment for the different purposes bein g quickly made.

The power-lever J is made of suitable.

(ea-operating with the dies, all constructed and operating substantially as described.

In testimony whereof I affix my signature, in presence of two witnesses, this 18th day of July, 1889.
