Application filed November 19, 1918, Serial No. 263,203.
prises frames pivoted together and having cutting blades secured thereto, with means for adjusting the frame with respect to the pivot, whereby to regulate the relat1on or the cutting edges of the blades with respect to each other, and means more particularly intended for taking up wear.
My invention further consists in a blade frame, a plate detachably secured thereto, said plate having a serrated forward edge, and a blade detachably secured to the frame with its inner end or heel interfitted with the serrated edge of the plate, with the inner faces of the plate and blade flush with each other.
This invention further consists in a shear mounting, and means for operating the movable blade of the shears by hand or foot power as preferred.
In the accompanying drawings Figure 1 is a View in perspectlve.
Fig. 2 is a similar View showing a slight change from foot to hand power.
Fig. 3 is a longitudinal section through the blade members; Fig. 4; is a side elevation of the fixed blade frame and blade in a reversed position; Fig. 5 is a detail view of one of the head members; Fig. 6 is a top plan view of the table; and Fig. '7 is a detail perspective view of the blade spring.
A and 13 represent the two blade frames. These are made of suitable size and length and are given the required strength.
As shown in Figs. 3 and 4 a plate a is detachably secured to the frame at or near the center of the latter, where the parts of the shears are pivoted together and the forward edge of the plate is provided with a xi-shaped notch Z) and the inner end or heel c of the blade 1, is correspondingly shaped to enter and fit this notch b, whereupon it is bolted or riveted to the frame as shown, with its inner face flush with the inner face Specification of Letters Patent.

Renewed June 30, 1920. Serial No. 393,095.
of the plate a, the blade being supported at the outer or rear edge by lugs 61? on the outer edge of the shear frame.
Each plate is provided with a transverse elongated slot 2 and 2 respectively which slots register with each other as one, when the plate of each plate is secured in place, and within these slots the hub 4 of the pivot 5, is fitted at the side, but the slots are of greater length than the major diameter of the hub, in order to admit of adjustment of the shear frames and blades with respect to the hub l and pivot 5, and this adjustment is effected by the two set screws or bolts 6 and 7, one above, and one below each hub, with their ends bearing thereupon on opposite sides thereof. To adjust the blades up and down with respect to each other, it is simply necessary to apply a wrench to unscrew one and tighten the other, to adjust the blades in one direction; and to adjust the blades in the opposite direction the order of turning the set screws or bolts is reversed.
To secure the hubs in place, each hub is provided with a head or plate 8 on one end, and this is provided with slots 9, through which the bolts 10 pass, and these screw into threaded holes in the heel of the adjacent blade to hold the hub securely in place, after adjustment.
25 indicates a flat spring having an orifice therein which receives the extended end held thereon by the nut 26. One end of the spring is slotted as at 27, and slidably secured to the frame B as at 27, while the other end is bent under upon itself, as at 28. and is adapted to bear against the plate B, the construction as a whole acting to maintain a lateral tension upon the shearing blades.
By these two adjustments the cutting edges of the blades may be set to cut as desired. The adjustment is capable of great refinement for the work to be done, and is simple and efiective.
As a convenient mounting, I have planned a table 12 (as shown in plate 1). This table is provided with a slot 13 (as shown in 6) and in this slot the lower blade a of the shears is adapted to be secured by means of bolts 12 passing through the rear 13 of the fixed blade A and the bracket 14: attached to the table 12, with the cutting edge extending there above a fraction of an inch, say three-eighths, (as shown in Fig. 1).
The table is mounted on suitable legs lt to give it the required support and height. A shaft 15 is mounted to rock in the brackets 16 depending from the table. A link 17 se cured on this shaft is pivotally connected with the link 18, and a spring 20 extends from the lower end oflink 18 to the floor or other ,fixed .point to normal-1y raise the upper'blade Bof the shears (as shown in igl) A lever 21 preterably made of several sections adjustably connected together is adapted .to be used either as a foot or hand lever, and for this purpose it has a socket 22 adapted to receive the foot piece 23 or the hand piece 24: (as shown in Fig. 2) as the case may be,
By lengthenin out the shaft 15 the hand or foot lever coifid be applied if desired at some distance from the'shears, and in fact several shears might be operated in this way f m a common P in More or less slight changes might be made in these details, as they are merely van incint t t m in dea o th invent o 1. Shears comprising blades, the heels of which are provided with transverse slots, a hu .fi tedthe ein v o adm t o t a ad'- justment of the blades with respect thereto, means connected with the blades for causing this vertical adjustment, and means for laterally pressing one blade against the other.
2- h ars c mpr g blad s having tra sse l t h rein, a h b t er in Withrespe to which the blades are adjustable, set screws extending through from opposite edges of the blades, and bearing against the hub whereby to adjust the blades vertically and independently of each other.
3. Shears comprising blades having transverse slots, a hub in the slots with respect to wh h th blad a adj table, s serews extending through from opposite edges of the blades and bearing against the hub, wlereby to adjust the blades vertically and dep ndent y of ea h other, the hub h v ng a slotted plate on its outer end and set screws extending through the slots into the heel of one blade, whereby to hold the hubs securely in place.
4. The combination with a shear frame, of a plate detachably secured thereto, said plate having .anotch ed forward edge, and a shear blade :det achably secured to the frame and fashioned at the rear end or heel to fit the notched edge of the plate, said blade d pt d to be bolted (to the shea frameh om ination with a shear a e, of a p a deta ha ly s ne the to, id plate having a notched forward edge, and a shear blade detaehably secured to the frame and fashioned at the rear end or heel to fit the notched edge (of the plate, said blade adapted to be bolted to the shear frame, the plate provided with a transverse slot, and an adjustable hub extending through said slot, and means for adjusting said hub.
