GAGE FOR SYHEARS.

Specification forming part of Letters Patent No. 43,6311, dated July 26, 1864.

.T0 all whom it may concern:

Be it known that I, CHARLES BRoMBAoH- ERof the city and State of New York, have invented, made, and applied to use a certain new and useful Improvement in adjusting the Gages of Shears; and I do hereby declare the following to be a full, clear, and exactdescription of the said invention, reference being had to theannexed drawings, making part of this specification, wherein- Figure l is a plan-o10 a shear fitted with said improved gage, and Fig. 2 is a side elevation of the same.

Similar marks ot' reference denote the same parts.

Shears t'or cutting paper, straw-boards, and other substances have heretofore been made with a gage, against which the edge of the material to be cut has been pressed, so as to determine the width of such material cut off by the shears. Such gages have been set upon a V-slide, and moved by hand. also been employed to move such gages.

With gages set by hand difficulty exists in bringing them accurately to position, because the person has no leverage with which to move the parts, and a blow froma hammeris often resorted to for completing the adjustment of the gage. With the screw the adjustment can be obtained accurately; but too unich time is consumed in making the changes of the gage that are required in many businesses. Besides the. loss of time, the handle of the screw has to be at some distance from the shear itself, which causes inconvenience to the operator, because he has to turn the screw while reaching over to measure the distance between the shear and gage. For these reasons the screw-gage is objected to and its une discontinued.

The nature ot' my said invention consists in arranging a rack` and pinion for moving the gage in such a manner that the handle for actuating the same is contiguous to the shearhandle, so bthat the operator can adjust the gage Without changing his position at the A screw has shears, and under circumstances where he can with ease and accuracy measure the distance between the gage and the stationary cutter or shear, and by said mechanism the gage can be adjusted with rapidity, and asufticient leverage is obtained to move the gage to `ex actly the desired point.

In the drawings, a is the frame carrying the table b and stationary cutter c, and d is the moving cutter. These parts are to be of any usual or desired construction and provided with a clamping device to holdthe material While being cut, said material lying on the table I).

c is the gage on a V-slide, f, upon a bed, g, sustained by the frame a. h is a rack extending at the side of the gage and passing beneath the stationary cutter o, (when the gage is near said cutter.) t' is a pinion on a shaft sustained in g and actuated by the handle Ir, which handle is contiguous to the handIeotthc cutter d, so that the operator can with ease and very quickly adjust the gage so as to cut oft' any desired width of material.

A clampingscrew may be litted at l, so as to hold the gage at any point to which it may be adjusted.

The advantages ot' my improvement will be apparent from the foregoing, and I remark that the size of the pinion t, or its shape, may be varied according to the requirements of the machine.

What I claim, and desire to secure by Letters Patent, is-

The handle, rack, and pinion or similar mechanism that actuates the gage, when said handle is contiguous to the handle ot' the shears, substantially as and for the purposes specified.

In witness whereof I have hereunto set my signature this 15th day of January, 1864.
