UNITED STATES PATENT OFFICE.

'GEORGE BENDER AND BENJAMIN F. CONNEB, OF NEW YORK, N. Y., ASSIGrNORS TO BENTLEY, CONNER & 00., OF SAME PLACE.

LEAD OR RULE CUTTER.

SPECIFICATION forming part of Letters Patent No. 532,521, dated January 15, 1895. 1

Application filed October 18, 1894. Serial No. 526,265. (No model.)

.rules to desired lengths, and has as its object certain improvements whereby the movable blade of the cutter can be readily adjusted at different angles so as to give a horizontal cut or a shear out, whereby either leads or brass rules may be cut with the same cutterblades.

Ourimprovements also relate to an adj ustable gage and to other details hereinafter described.

In the drawings, Figure l, is a right end view of the cutter. Fig. 2, is a view of the opposite end. Fig. 3, is a front elevation, and Fig. 4: is aplan view,with the upper portion of the cutter broken away.

Similar letters designate similar parts in all the drawings.

The base or frame of the cutter consists of the casting A, to which is attached the stationary center blade B. The arm 0 is pivoted to the frame A by the bolt D, and is provided with an extended portion E which fits evenly against the side of the frame A, and by its extended bearing prevents lateral vibration in the arm 0 when in operation. The lever C is pivoted to the standard A of the base A, and is connected to the arm 0 by link 0 Ontthe side of the arm 0, next to the sta tionary blade B, is a rabbet to accommodate the movable blade F, which is 'pivoted to the arm 0 by the pivot f. A set screw 9 passes through a slot 0 in the arm 0, and engages with the blade F. A rod h isjournaled in the arm 0 and is provided at its inner end witha cam 'i, the upper side of which bearsagainst the upper edge of the rabbet, while the lower side thereof engages the upper edge of the blade F. By. loosening the set screw 9, the blade F is left free upon its pivot f. The cam 'iis then turned so asto interpose its longer or shorter diameter between the blade F and the arm 0. The blade is then brought firmly against the cam, and secured in place by the set screw g. By thismeans any desired angle can be given to the blade F, and a firm backing is provided for it by means of the cam 2 G is a graduated gage, which slides in the guides H, H and is provided at its end with the stop I.

J is a' locking cam which fits into the recesses j jj, which are placed at pica distances on the lower side of the gage G. The for ward edge of the cam J is beveled to correspond with the inclined forward sides of the recessesjj j, so that when the gage is slid approximately to the desired position, the cam J is turned into position and by the pressure of its beveled edge against the inclined side of the groove forces the gage forward until the vertical rear side of the recess comes in contact with the rear side of the cam, when the gage will be locked at a true pica distance.

If an odd length is to be cut, the distance is measured between the guide H and the stop K on the gage G, which is then secured by the set screw L.

M is an extended arm which is adapted to support the forward end of the gage G and alsoserves to sustain the lead or rule as it is fed forward to the stop I. This prevents the lead from bending or sagging or springing so as to give an uneven measure when out. By this means we secure a lead and rule outter with a single bed N to support the metal while being cut, and-with a single movable cutting blade which can be readily adjusted at different angles to the stationary cutting blade, and when adjusted shall be firm and durable. We also secure a greatly improved gage, and an automatic justifying lock for the same, and we provide a supportboth for the extended end of the gage and for the projecting end of the lead or rule.

Having thus described our invention, what we claim, and desire to secure by Letters Patent of the United States, is

1. In alead and rule cutter the combination with a bed provided with a stationary cutter blade, of an oscillating arm, with an extended rear end, pivoted to said bed, provided with a 'rabbeted recess therein, a movable cutter-blad e, adjusted in said recess, piv- ICO oted at one end, supported at its other end by an eccentric cam interposed between the cutter-blade and the arm, and secured in place by a set screw, substantially as and for the purposes set forth.

2. In a lead and rule cutter an adjustable gage G provided at pica distances with recesses having inclined forward edges and vertical rear edges,a locking cam provided with a similarly inclined forward edge and a vertical rear edge, adapted to adjust the gage to true pica measures by locking into said recesses, substantially as and for the purposes set forth.

The combination in a lead and rule outter of an adjustable graduated gage, provided with a stop at its forward end to arrest the lead or rule, a measuring stop attached to said gage at the same distance from the rear guide as the front stop is from the cutting blades; recesses at pica distances upon said gage provided with inclined forward sides and vertical rear sides, a locking cam with inclinedforward edge and vertical rear edge adapted to look into said recesses; guides for said gage to slide in, and a set screw in one of said guides to secure the gage, substantially as and for the purposes set forth.

4. In a lead and rule cutter, the combination of the base or frame A, stationary blade B, the rabbeted arm 0 pivoted thereto, provided with a rear extension E, cutter blade F, pivot f, set screw g, rod h, cam i, graduated gage G, provided with the stops I and K, and recesses j j j, locking cam J, set screw L, guides H, H, and arm M, substantially as and for the purposes set forth.
