` may concern: Be it known that I, ROBERT HOLDING, a citizen of the United States, residing at Chicago, county of Cook, and State of Illi- Metal Machinesfof which the following is a full, clear, and exact speciiication.
'This invention' relates to machines for slitting and expanding sheet-metal, principally forv the purpose of producing a in which the or cutterto construction,
trellis-like structure, commonly employed as a substitute for laths, and other uses, and the linvent-ion is especially 'designed as an improvement upon the character of machine for accomplishing metal is slitted and the strands expanded or spread apart by a'plurality of knives or4 shearingpmembers, cooperating with a com'n pamon member usually arranged att-he edge ofthe table which supports the sheet dui-in the operation, as, for example, themachine shown in the patent to J F.- Golding, No. 581,7l3,granted May 4, 1897; and the ins vent-ion has for its primary'object to' pro-1 vide an improved machine of this character, in which the spring away from its companionme'mber, due to the resistance of the metal, will be neutralized or ove'rcome by. such resistance. Anotherobjectof the invention 4is toprovide an im'proved expanded 'metal machine cutters may be readily replaced 'in their proper position'safter' without the necessity of the fine adjustment heretofore required.
lVith these ends lin view, the invention consists in the -combination, andv *arrangement of-parts by which said objects, and certain other objects hereinafter appearing, are attained, all as fully described with ref-4 a side elevation, partly inlvertical section, ofthe cutters, the 'supporting table, and the sheet. of metal therein-between. Fig. 4 is an enlarged detail vertical section taken on the line of Fig. 3. Fig. 5 lis a perspective this Work, in Which the' tendency of the shearing blade being ground,`
particularly pointed out in the claims.v
i l s features .of novelty in the .View ofone of the cutters.'
shoulder l2, and these And Fig. 6 is a detail perspective View of the cutter lug or clam In the aforesaid Golding machine, a single and useful sheet of met-al at atime is acted upon by the knives or cutters, which are ing and falling and are operatively related to a companion shear arranged along the edge of the table which supports the sheet, and in practice it is found that the ,resista-nce of the sheet causes the movable cutters, or those carried by the cross-head, to spring away from the companion shear or member on the edge of the' table, especially yafter vthey become slightly ,worn or dulled from use.I In order to overcome this objectionable yieldingmovement of the cooperating membersl of the cutters, vI operate neously, bymeans of two sets'of movable cutters 3', 4, which are situated between their companion cutters or members 5, 6, respectively, so that the resistance of one sheet will neutralize or overcome the resistance of the other sheet, thereby Aalso neutralizing an Y tendency of the cutter-head 7, Vwhich carries the cutters 3, 4, tomove in either direction. The companion cutters 5, 6, are mounted rigidly upon., the ina-'in frame or table 8, which supports the sheets 9, 10, and conseq'uently said cutters 5, 6, are held firmly in position during the cutting operation. .As
carried on a risbet-tershown in Fig. l, the main 'frame orl table-is formed with a recess 11 for the accommodation of the sheets after they have been cut and expanded, and below this recess the side portions of the frame or table are firmly connected together.
The movable cross-head, 'or cutter-head, 7, which carries the `cutters 8, 4, is provided on each side .with a depending flange' or have their inner or opposed faces accurately machined or formed' in' line with the operative faces of the lower cutters onshears 5, G, so that the .inner 'facesof said flanges andshears will lie in the same perpendicular plane, and the cutters 3, 4, are composed .of movable blocks or sections, as shown 1n Fig. 5, which are of box-like formation, each having two le'gs or branches 13, 14, and a V-shaped cutting end '15,- Wlnch engages the metal and produces the necessary expansion as 1t forms the slit which-producesthe strand. The outer faces these box-like cutting members 3, 4, are v cross-head or cutter-bzw,A

'ln order that these cutter men1- bers 3, l, may be tjigidlyclamped and. held in place, tlieyare supported at their upper edges directly against the lower side ot' the cutter-bead 7, which of course holds tbem against upward movement relative to the cuttciiiead, and they are supported against one anotheii' as shown in Fig. 3, Wbicb holds them against lateral motion, While they are held snugly against tbe flange or shoulder- 12 by any suitable clamp, such as shown in Fig. G, comprising u bead or flange-lndlich tits against their inner sides, und a stud or bolt 17 which passes through the shoulder l2 und is provided viitb a nut 18 arranged. against tbe outer tace of the shoulder, tbese heads Ai6-bem@ of a shape complementary to tbe cutter members 8, 4t, so that tbey Will bold each other against rotation. Eil-cb of tbc cutter members 3, fl, is rioldlyl held against movement in a direction away from tbeir companion members 5, 6, by any suitable abutment, sucb as a set-screw "i9 sere-W- tbreaded in a depending` portion 2d, otsubstantiel proportions, formed on the lower side of tbe cutterbead 7, tbe set-screws 19 being preferably situated neat the lower ends or points of the cutters 3, fl, 'Where tbestrain is greatest,
