Application filed December 30,, 1911 Serial no. 668,794.

To all whom it may concern 3 Be it known that I, Amos CALLEsoN, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Machines for Operating on Sheet Material, of which the following is a specification.

This invention relates to machines for forming'articles of sheet metal, and particle larly to that class of such machines which are adapted to operate'upon sheet material that is two or more times wider than the diameter of the cut whereby each article is formed. Usually in these. machines a gang of two or more dies is employed, such dies at each operation forming a row or se ries of cuts that is substantially coextensive 'with the width of the sheet. In the present instance, however, but a single die is employed, and in order to make clear how the die is made to operate upon all parts of the sheet it may be well to preface the following detailed description of the invention with a brief outline of the steps performed.

The die is made to produce cuts one after another in rows or series, the rows being parallel, and as fast as each row is formed the apertured part or scrap portion of the sheet is removed, thereby allowing the sheet to be shifted transversely so as to stand within the effective range of the die for the eutting'of the next adjacent row of cuts. Preferably, instead of beginning the cutting of the several rows at the same edge of thesheet; the odd rows arestarted from one edge and the even rows from the opposite v edge of the sheet so that during the feeding of the sheet in each direction a row of cuts will be produced.

Two embodiments of the invention are disclosed herein: In one the feeding of the sheets to form each row of cuts is performed byhand under automatic control, the trans verse shifting of the sheet after the scrap appertaining to a finished row of cuts is removed being accomplished by the aetionof gravity on the sheet; in the other the operation is substantially completely automatic, the. attendant'having merely to supply the machine with sheets one after another and start it when it automatically stops upon completing its work upon any one sheet.

' In the'accompanying drawings, Figure 1 is a side elevation ofthe'machine; Fig. 2

is a front elevation; Fig. 3 is a piaii view illustrating the table on which a sheet is .front elevation of the two severing means and. parts of their cont-rolling mechanism;

In the base a is arranged a frame Z) which is pivotally supported in the base so that it may be tilted backward at any desired angle; In this frame is journaled the main shaft 0, carrying, free thereon, a driving pulley (Z and a clutch e of the type shown in Fig. 31 0f the U. S. Letters Patent No. 913182; it is unnecessary to describe this clutch in detail herein, in view of its full illustration and description in the said patent, it being sufficient to explain that when the handle f in Fig. 2 is held depressed, as by being engaged in the notched stop mechanism comes into play to lock the pulley cl tothe shaft '0, so that said shat'twill rotate with the pulley, and when said handle is. released from said stop and rises under the action of the spring [1. said mechanism is caused to release the pulley from the shaft, so that the pulley runs free on the shaft.

At the back of the bed i of the frame I) is arranged the lower member j (Figs. 2, 3 and 5) of the die mechanism,'the stops afforded by the ,upper member 7.: of which is carried by the plunger Z guided in suitable ways in the frame 0 and actuated from a crank m on the shaft 0 by the pltman a. On

the bed 'i is arranged the sheet support or table 0, the same being adjustable forward and back thereon, that is, toward and from the die mechanism; the adjustment may be accomplished by a hand-screw p tapped into' a depending lug g on the table and bearing against the front of. the bed '1', the table being kept true in adjusting it by the two pinions 1' fixed on the ends of a shaft 8 journaled in the table and meshing with fixed racks t on the table. At each side of the I die mechanism there is bolted to the bed rear edge of the sheet to be ope 'ated upon,

and it has a laterally projecting overhang n. 0 denotes straight-edges disposed one on one side and the other on the other side of the brackets it, each being formed of a strip of angle iron and supported at its outer end by an arm 3/ projecting from .the table 0 and having its inner end formed with-a slot 2 to receive a screw 2 in the overhang of the adjoining bracket u, the slots 2, when the screws are released, allowing the straight-edges to be adjusted with the table.

3 is an inclined lip on each straight-edge to insure the sheet-edge coming squarely'to rest against the straight-edges.

.When a sheet is introduced into the machine, standing in contact with one of .the straight-edges, it is received by a carrier which is made to grip it and hold it firmly as it is fed lengthwise of the table 0 under the reciprocating die-member. This carrier is shown best in Figs. 5, 12, 13, 1 1 and 15 and itis constructed as follows: 1 is a rack having stprare-cut teeth 5 along its front edge and a square recess 6 near each end thereof in its rear edge, and also having an upstanding projection? near each end. The nacmg at 5 between the two teeth at eacn end of the rack is greater-than the spacings between the remaining teeth of the rack, all of which spacings, it may be noted, are uniform. Each recess 6 receives a square stud 8 projecting downwardly from a, forked bracket 9 and atfording journals for the rollers 10 and 11. The brackets 9 are formed with tables 12 and above the table each is forked in plan (Fig. 13) so as to receive the pivoted presser 13. the table and presser having a mating projection and recess 1%. Each presser or jaw is normally held in the dotted line position in Fig. 14 by a spring 15 and is forced into gripping relation to the table 12 so as to indent and grip the interposed sheet by a cam 16 formed ona sectional shaft 17 carrying the handle 18 (Figs. 1, 2,3 and 5) whereby the shaft is turned and the carrier bodily moved, in the manner to be described, along a path parallel with the straight-edges w. The shaft 17 is held against endwise movement by collars 19 and 20 which abut against the opposite sides of the left-hand bracket 9 in Fig. The right-hand bracket 9 is capable of slight movement toward the Otllcl' bracket because the recess 6 receiving its stud 8 slightly wider than said stud, such movement being however normally resisted by a spring 21 interposed between the right-hand bracket and a collar 22 fixed on the shaft. 23 is a collar fixed on shaft 17 at the right of righthand collar 9'and housinga spring-pin 2 bearing upon a camway 25 in the side of said bracket, the wiping of the pin over said camway as the shaft'is turned to cause the pressers 13 to grip the sheet producing a shifting of the right-hand bracket toward the left-hand bracket to center the sheet. The carrier is arranged to travel in the rabbet 26 at the back of the table 0, being held therein by a plate 27 having an inside'longitud'inal rib 28 in the grooves beside which the rollers 11 run (Figs. 5" and 14). v

' As the operator, by means of the handle 18, movesthe carrier, gripping the sheet, across the machine, the die mechanism operates intermittently on the sheet, forming a series or row of cuts. -These .cuts should be uniformly spaeed from each other, and to opening upon the rabbet 26, thesame having a groove 31 on its under side to receive a sliding pawl 32 which cooperates with the teeth 5 of rack 4, the-pawl being laterally cushioned and adapted-to be adjusted laterally by turning screws 3.3.between which and pins 34, guided in the block and engaging opposite sides of the pawl, are interposed springs 35. The pawlis slotted to receive one arm of a bell-crank lever 36 (which arm has-a cushioned engagement with the pawl by virtue of aspring-pin 37 against which the'arm directly bears) the bell-crank lever 36 is fulcrumed betweencollars '38 on the shaft 8 and its free arm is connected by a itman 39 with a lever 40 fulcrumed in the rame b, the said lever being connected by a pitman 41 with a lever 42, also pi oted in the frame?) and carrying a roller 43 bearing upon some going part, such as a cam 44 on shaft (1, the free end of lever 42 being preferably shaped as a handle 45. A spring 46 holdslever 40 in such position that the roller o-n thev lever 42 normally presses againstt-he cam. In view of this construction the pawl 32 normally restrains the rack (and hence the carrier) against advance; but on each rotation of the shaft 0 the pawl is withdrawn, releasing the rack, quickly returning, however, into engagement with it.

jlhus, manual pressure being applied to thecarrier. to effect its advance across the ma chine, such advance is intermittent 1-n character, the several increments being uniform;

that is to say all the increments'are uniform .except the last in each direction, which,

owing to the relatively augmented spacing at 5 between the last two teeth of the rack at each end thereof, is longer than the rest for a purpose to be explained hereafter in referenee to Fig. 25.

- The cutting away of the scrap upon the forming of a series or row of cuts at the back of the sheet is effected as follows: Referring to Figs. 6 to 10, in each bracket 50.44 is pivoted a'knife 47 Whose knife-proper 48 has shearing coaction with a fixed knife 49 secured to the front of the bracket. Overlying the front face of the knife 47 and secured to the bracket is a plate 50, the adjoining outer edges of said plate and knife 49 being beveled to form a flaring entrance "51 facilitating the admission of the sheet to the mouth o of bracket u. A spindle 52 is pivoted to and projects upwardly from the knife and around it is coiled a spring 53 interposed .between the top of the bracket u and adjusting nuts 54 on the spindle and acting to hold the knife normally elevated. Before proceeding to describe how each knife 47 is caused to move to shear off the scrap it may. be well to remark that the bottom surface 'of. the mouth 0; of e h bracket u slopes relatively outwardly (i. e., away from the other bracket) as at 55, permitting the scrap to fall down between the back of the table 0 and the adjoining straight-edge 02. When the carrier is traveling in either direction the relatively remote sheet severing means is acting and the other is idle. The action of each severing means is intermittent, being effected from the plunger Z, so that each time the die mecha-- nism operates to form a cut the severing means operates to sheer or cut away the scrap. A sliding dog 56 (Figs. 6, 7, 8 and 11) is movable in a groove. 57 in the front of each knife 47 so as to project from the end of the knife or recede into the same. When the dog projects from the knife it stands within the path of movement of a foot 58 on the'side of the plunger Z. said foot therefore depressing the knife when the plunger descends. At each end of-the table 0 is fulcrumeda lever 59, the said levers being connected so as to move to-- gether by a link 60 and said levers being also respectively connected with the dogs 56 by links 61. Pivoted to each lever is a pawl 62 having a T-shaped head which may catch in a notch 63 in the end of the plate 27 and which also lies within the path of movement of the adjoining projection 7 on the rack 4 of the carrier. Opposite the adjoining end of the rack 4 the lever 59 carries a set screw 64 against which the rack, after its projection 7 has tripped the pawl 62 out of the notch 63, impinges to shift said lever and the other lever 59 on their fulcra, thereby causing one of the dogs 56 to retract and the other to project from the knives 57.

The operation of the machine shown in the first eighteen figures of the drawings is as follows: A sheet being placed upon the table 0 so as to enter the gripping means of thecarrier it falls with its rear edge in contact with the corresponding straightedge 00, it being understood that at this time the carrier is at one of its limits of movement. The operator now grasps the handle 18 and presses it downwardly, thus gripping the sheet. Having started the shaft 0 rotating by pulling down upon the handle f, the carrier, by means of handle 18, is manually moved across the machine, the trip mechanism so timing its intermittent advances that each time the die mechanism operates to form a cut the carrier moves one step, that is, just sufficiently to bring the sheet in position for the forming of the next cut. Assuming that the carrier is being advanced to the right in Fig. 2, the dog of right-hand knife 47 will be project ing into the path of the foot 58 on the plunger, so that each time the latter descends a. cut is formed by the right-hand isc Cir

shearing means, a complete sequence of such cuts resulting in the part of the sheet back'of the shearing line (scrap) being' finally cut away. Referring to Fig. 25, A

designates the first row of cuts formed by and it, etc, indicating the remains uncut (as at X, Fig. 23) byihe die mechanism at the end of each row. To prevent the die from operating on the sheet at X the last impulse which the carrier is allowed to receive in each direction exceeds all the other impulses, owing to the spacing 5 in Fig. 13, the sheet thus clearing the die mechanism before it can again be operated upon by the same. When the scrap has be n entirely cleared away (the carrier now having reached its limit of movement in one direction), the operator raises the handle '18 to open the gripping mechanism of the carrier, allowing the sheet to fall again with its back edge in contact with the straightedge. The handle 18 is now again depressed to grip the sheet, and then employed to move the carrier in the reverse direction. At the end of its first movement, the rack of the carrier tripped the right-hand pawl (32 and" shifted the levers 59 so that the dog of the right-hand knife 47 was retracted and the dog of the left-hand knife projected into the path of the correspomling foot on the plunger. In the return movement of the carrier, therefore, the left hand shearing means is active and the right-hand shearing means inactive.

The operation so far as the die mechanism and shearing means is concerned is the same in the return movement of the carrier as it was in the movement thereof to the right, resulting in the row B of cuts 1, 2, 3. at, etc.,

produced bythe die mechanism and the line of cuts B produced by the shearing means. Z in Fig. 25 denotes indentations formed by the projections and recesses 14 of the gripping means on the carrier. 65 denotes safety stops against either of which a toe 66 on the adjoining collar 19 or 23 of the carrier will engage to prevent the operator from turning the handle 18 to open the gripping meohanism, anticipating that the sheet is ready to be released so as to fall back against the straight-edge before the carrier has completed its full movement in either direction.

Iii-Figs. 19 to 24, the shaft 0 (carrying the loose pulley (Z and a clutch-e like clutch c) has a crank 7 wherefrom, through a pitman 68, a toothed segment 69, rocking in frame b, -is.aetuated. This segment meshes with the teeth 70 on the under side of a rack 71 sliding in a gnideway 72 in table a,

of cutsi'ormed by the die mechanism are staggered, i by preference, to reduce the waste, the sheet I the teeth 73 of said rack being engaged by either of two reversely set spring-pressed pawls Tl pivoted in a bar T5 which slides in the rabbet 26, being therein held by the plate To. carrier in this machine) carries two brackets 77 having inwardly extending tables 78 and forked and otherwise shaped like the brackets 9 and receiving the pivoted springactuated pressers T9 which are moved by the cam-shaft 8O journaled in said buckets and provided with the grooved cams 81. Housed in the top of the bar is a slide-rod 82 having two rounded notches 83 spaced farther apart than the two pins S-t on the pawls which ride on the thusnotched fa'ce of the slidebar; when one pawl moves rearwardly and is thus engageable with the teeth 73 of the rack 71, its pin being then in one of the notches of the slide-rod, the other pawl remains withheld out of the path of the teeth. Adjustable stop-screws 85 are arranged on the table so that the end of the slide-rod will engage one of them in each direction of movement of the carricr. The severing means 86 are the same as those already described, and'their dogs 87 areconnected with the levers 88 (interconnected by the link 89) by the links 90".

The rocking of the segment 69 is thus trans-' mitted by one of the pawls T4 to the carrier and as thecarrier reaches its limit of. movement inreither direction the slide-bar carried thereby contacts with a stop-screw 85 and is shifted so as to. disengage that pawl from the rack and allow the other to become operative; in this way the carriers movement is automatically reversed. It is of course necessary, when the carrier reaches its limit of movement in either direction, to cause it to release the sheet so that (the scrap having been removed) it will fall back against the straight-edge m, and this is accomplished by fixed pins 91 one of which will be received bythe adjoining grooved cam 81 and cause an oscillation of the camshaft 80. When the sheet being operated upon is exhausted the machine stops automatically. The hand-lever 7" is caused at this time to be disengaged from the stop g' (so that the clutch e releases the pulley d) by a lever 92 connected with a slide 93,

moving in a bracket 94, by the pitman 94.

To insure the sheet being operated upon falling into proper contact with the straightedge when released by the gripping mechanism the-carrier arms 99, having notched pivoted feet 100 to engage the outer edge of,

This bar (fol-min part of the v the sheet, are pivotedin an upright frame 96 rising from the brackets 9. These-may be operated either by spring or positive means. I

The combination with a punching press of a movable feed table having solely a lateral I'IIOVQIHPI'lt, guiding means therefor.rcstraining' it to a determined lateral path, said table having stop teeth, a movable stop at a fixed location, engaging said teeth, and means operated by the press for reciprocating said step to withdraw it and permit a,feeding movement of the table after each punching operation.

33. The combination with a punching press of a movable feed table having solely a lateral movement, guiding means therefor restraining 1t to a determined lateral path,

said table having an operating handle and adapted upon being turned to operate said levers.

37. The combination with a punching press of a movable feed table having solely a lateral movement, guiding means therefor restraining it to a determined path, clamping levers thereon at opposite sides for gripping the opposite margins of the sheet, and

an operating handle extending laterally over the feed table, having eccentric portions engaging said levers, whereby upon turning the handle the levers are simultaneously operated.

38. The combination with a punching press having a punch and scrap cutter, of a movable feed table having solely a lateral movement, clamping means on said table for gripping a sheet to be punched, and a stationary gage related to said scrap cutter for limiting'the forward feed of the sheet relatively to the table to the correct distance between lateral rows of punchings.

39. T he combination with a punching press of a feed table having solely a lateral movement, said table adapted to carry a sheet to be punched and to permit said sheet to be fed forward over the table, and clamp-- ing means on said table for gripping such sheet, whereby the lateral feed of the sheet is performed by moving said table, and the forward feed of the sheet between rows ping points of said table in its lateral feeding movements.

In testimony whereofI affix my signature in presence of two witnesses.
