in Machines for Punching and Cutting Angle-Plates, of which the following is. ai

specification. A v p The invention relates'to machines for cutting and punching the rivet holesA in angle plates for use in fabricating metal structures, and more especially to machines inv which these operations are effected simul` taneously or at one operation. of thema- `what lower to facilitate the delivery lof the "Ji punched and sheared angle plates. Suitable chine. l v f The objectsandadvantages of the invei-f tion will inv part be set forth hereinafter,1

and in part will be obvious herefrom. vThe invention consists in the novel parts, co'nstructions, arrangements, combinations and improvements herein shown and described.

The accompanying drawings, hereiny re' ferred to, and constituting a part hereof,

illustrate one embodiment of the invention,

and together with the description serve to illustrate the principles of the invention.

Of the drawings:

Figure 1 is an elevation of a machine constructed in accordance with the invention, and is a view lookingat Fig. 2 from the right;

Fig. 2 is an elevation, with parts in s ection, looking at Fig. 1 from the left;

Fig. 3 is a fragmentary elevation of the lower part of Fig. 2; with parts removed.

Fig. 4 is a central section on the line A-,B of Fig. 3, looking from the right, but showin wedge 4,0 in elevation;

Fig. 5 is a transverse fragmentary section, on an enlarged scale of the central part of Fig. 2showing the parts in position to permit longitudinal travel of the angle bar; and

Fig. 6 is a figure corresponding to Fig.4

5 but showing the parts with ,the -work clampedor gripped, and at the vcompletion of the punching operation.

Referring to the accompanying dredwin-gs",l illustrating by way of example one embodiment of the invention, means are provided in tlie machine for -feeding in from time to` time as needed or used by the machine, a stock angle piece, from which the angles or angle' plates are cut successively and punched with the requisite number' of rivet holes, the stock piece being then fed forward forV a repetition of theoperation. In the jembodied form of such means, a series of rolls lare provided, said rolls being preferably of -double conoidal form, the angle: bar or plate resting thereon in inverted position with its apex or vertex up. The roll or rolls at the left hand or delivery end are some- 1 stopping and gaging means are also provided for regulating or varying the length of angle plate to be cut off. As embodied a bracket 3 is supported from the machine frame, and may be eXtensible in itself, if desired. Carried by the bracket 3 is an internally screw threaded support 4; Screwed in the internally threaded support 4 is a screw threaded'rod 5 provided with a hand wheel 6. Driving mechanism of any convenient form is provided for the rolls, 1 (not shown in the drawing).

In accordance with certain features of the invention, means are provided whereby a previously punched section is cut oif while another section of the angle baror piece is being punched or in position to be punched. Thus the measuring and gaging device operates both to position onesection of the angle bar oi' plate for the cutting mechanism and vto position or measure another section there- 15 is in mesh with a gear wheel 16, mounted loosely upon shaft 17 to rotate freely thereon, Meshing with pinion 16 is an intermediate gear 18 supported on a shaft 19, carried by the machine frame. Intermediate gear 18 drives gear 2Q, which gear 20 is mounted loosely on shaft 2l to rotate freely thereon.

Referring more particularly to the punchin mechanism for the angle plates, means are provided for alternately holding the plate firmly for the punching operation and for then freeing it while it is fed forward to bring a new length into position to be punched, and moving the punched end forward to be cut. In the embodied form of such means, holding devices are provided acting at and near the vertex of the angle piece or plate to hold it lirmly in posltion, and at the same time bringing the dies firmly against the two faces or sides of the angle Yplate preparatory to punching. In such embodiment a block or anvil 25 is carried upon the machine frame above the work. Said block 25 has a longitudinally arranged downwardly opening V-shaped guideway or recess 26 therein extending longitudinally of the machine just above the apex or vertex of the angle piece as it is fed forward by the rollers 1 into positionto be punched. Adjacent to said block or anvil 25 are two slidably arranged die carrying blocks 27 and 28, mounted to slide in guideways formed by the lower, "external faces 29 and 30 of the anvil 25 and by the upper faces of the inclined parts 31 and 32 carried upon or constituting a part of the machine frame. Said die blocks 27 and 28 also provide guidelways for the angle piece and serve also as guides for the punches. As embodied each of said die blocks is of similar construction and provided with two series of dies 33 and 34. Above these series of dies each block is provided with a recess 35 extending longitudinally therethrough, the two legs or iianges of the angle piece m extending into said recesses, and traveling therealong during the feeding forward of the work. Suitable orifices and passageways communlcate with the dies to permit the punchings to drop away. Guideways 36 and 37 in series corresponding to the dies, are provided for the punches.

Means are provided for permitting the die carrying blocks 27 and 28 to firmly press the dies against the angle plate and to press the angle plate iirmlyagainst the V-groove 26 in anvil 25, and for alternately permitting the parts to move back into the disengaging position to permit the forward feed of the work. As embodied a wedge 40 is reciprocably mounted in a guiding aperture 41 in the machine frame. The apex of the wedge 40 fits between inclined faces 42 on thecontiguous inner faces of the .die

carrying blocks 26 and 27. The wedge 40 is carried upon reciprocable rods 43, mounted in the machine frame. l

Means are provided whereby the clamping and releasing of the angle bar ac is effected, and further such means are provided operative when only one leg or flange of the angle bar :u is being punched without necessitating the otherwise idle operation of the punches on the other side of the machine.

As embodied said actuating rods 43 are pivotally connected to an arm or arms 50 fixed to a shaft 51, to which shaft isalso fixed an arm 52. Pivotally connected to arm 52 is a link 53 provided with a head 54. Said head 54 slides within a hollow cylinder 55 and works against a coiled spring 56. Said spring 56 is coiled about the rod 53 and is 1n compression between the' head 54 of said' rod 53, and a head 57 screw-threaded into the end of the cylinder 55. Said cylinder 55 is fixed upon a rod 58, pivotally connected to a crank plate 59 on the left hand end of shaft 17, (Fig. 1). l

Means are provided for starting the punching mechanism and for stopping it after one operation. As embodied, upon the right hand end of 'shaft 17 is shown a clutch connecting said shaft to driving gear 16 for a single revolution. As embodied a clutch member 60 is splined or otherwise arranged to slide along shaft 17 while rotating therewith. A corresponding clutch member 61 is fixed to and rotates with driven gear 16.

`Glutch member 60 is impelled toward the clutch member 61 by spiral spring 62. In the periphery of clutch member 6() is a cam groove 63 into which projects a spring pressed, slidable pin 64. The spring 65 acts to project pin 64 into the groove 63. Suitable means for retracting the spring 64 are provided, and as embodied a solenoid 66 is employed for this purpose, which solenoid may be electrically energized in a suitable manner, and this may be done from a perforated sheet such as is shown in application Serial No. 814,380, filed January 26, 1914 of T. P. Payne. The momentary retraction of the pin 64 permits the escape of the clutch member 60 which immediately engages the driven clutch member 61, and the shaft 17 begins to rotate. The pin 64 then renters groove 63 and on engaging cam menace sufficient continuance of therequisite pressure upon the die blocks to permit the punching operation being performed While the angle plate is held clamped. When the wedge 40 is driven up, brou ht firmly against the inner sides of the two egs or flanges of the angle plate, and the vertex of the angle plate is pressed into the groove 26 and it is thus powerfully clamped for the punching operation.

Additional means for operating wedges 40 are provided, so that the clamping is effected, whether one or both legs of the angle plate are punched. In'the embodied form, a spur gear 7 0 is in mesh with pinion 15, said spur gear being mounted -upon shaft 71. A similar clutching device and control therefor (not shown) to that used upon the other side of the machine is provided. Pivotally connected to a crank plate v7 2 is a rod 73. Said rod 73 works in the interior of a hollow cylinder 74, having a pin and slot connection 7 5 therewith. A-coil spring 7 6 -is in compression between the end of ythe rod 74 and the bottom of cylinder 75. CyL` inder 75 is continued as a rod 77 andsaidrod 77 is pivotally connected with alever arm 78. Said lever arm 78 is xed to shaft 51, already described in connection with thesimilar mechanism on the other side of the machine. The manner of operation will be.

the same or similar to that already described for the other side of the machine. Sufhcient clearance will be provided in cylinders 55 and 7 5 to permit either the separate or joint action of the two mechanisms.

The punching means(` are duplicatedY on both sides of the machine 'to punch both legs of the angle m simultaneously or to punch either leg separately. The embodied form of punching means (see especially right hand side Fig. 2) comprises a reciprocable block 80, mounted in suitable guideways 81 in the machine frame. Said guideways extend upwardly, and at their upper end are provided with journals 82 for shaft 17. The central portion of shaft 17, between the journals 82 constitutes a crank- 83 carrying a connecting rod 84, connected to the reciprocable block 80. The 'block'80 is provided with longitudinally arranged grooves 88 for the heads of punches 85 and 86, which punches are carried in the apertures 36 and 37 of the die blocks. The mechanism just described serves to punch the rivet holes inv one leg or flange of the angle plate A `Assiiriilag. mechanism, which need not be described` in detailLis provided for the other leor of the angle plate and is operated from the shaft 71. The punches are thus driven down through the tightly clamped angle plates and then retracted preparatory to the release of the angle plate and the feed forward thereof. The position and movement the die blocks arey gitudinally with respect to the angle bar or stock piece and this also, with suitable positioning of stop 5, positions them with respect to the shear thereby providing for both the punching and shearing of angle plates of different sizes. As embodied, the die vblocks 27 and 28 engage with the wedge 40 by means of vertically arranged tongue and groove connections 90 (referred to Fig. 4), whereby the die blocks and wedge will move together horizontally for positioning as stated, but are free to move relatively to each other during the wedging action. It will be understood also that the punches, which are reciprocably mounted in the apertures 36 and 37, will be carried along with the die blocks, sliding along in the grooves 88 in the punch actuating block 80, but being always in position to be actuated by block 80. A longitudinally arranged screw -threaded rod 91 (referred to Fig. 4) extends within a recess in the bottom of wedge 40.

hreaded on said screw rod 91 is a square j )nut 92, resting in an enlarged aperture 93 ,in the central bottom part of wedge 40. The nut rests also on the bottom of the groove 41 in the machine frame, so that it travels longitudinally when the rod 91 is turned, and when so traveling carries the wedge 40 and the die blocks with it. 91 is provided with a hand wheel 94, and has suitable bearings in the machine frame.

The embodied form of cutting means comprises a shearing blade or edge 100 fixed upon the machine frame, just above the place of emergence of the punched angle plate Fixed upon the; machine frame are vertical guides 101 and 102. Within these guides reciprocate a plate 103 having a V shaped shearing edge 104 corresponding to the shear edge 100. The plate 103 is recessed at 105 to clear the rod 91. The plate 103 is--likewise recessed at 106. In the recess 106 is a horizontally slidable block 107. The block 107 has a cylindrical aperture therein within which aperture fits rotatably an eccentric end 108 of shaft 21. Upon shaft 21 is a clutch member 109 rot-ating with the shaft 21 but slidable therealong. A corresponding clutch member 110 is fixed to the driven gear 20. Clutch member 109 is im-v The screw rod as solenoid 114 are provided for momentarily withdrawing the pin 112 and permitting a single rotation of the shaft 21, and a consequent operation of the shear members 101 and 104. The cam 115 retracts the clutch member 109 to stop shaft 21, all the foregoing being similar to the clutch mechanism already described, and operating in .the same manner. The successively punched and cut-off angle plates are fed out or discharged forwardly and downwardly by the roll 1 at the left in Fig. 1,

The Vtwo punching mechanisms and the cutting mechanism can be operated together, or singly as desired, by means of their various clutch controls, Whether these be operated automatically or not.

In Fig. 1 is shown diagrammatically the automatic control for the clutches. A distance record sheet, or other controlling sheet 117, has coperating therewith contactslli. Contacts 118 are in circuit 119, in which circuit are also solenoids 66 and 114, previously described. The double-throw switch 120 releases one or both clutches when motor circuit 121 for the feed motor for feed rolls 1 is broken. The timing of the various shafts may be determined and regulated by the adjustment and placing of the gears.

It will be understood that the machine is adapted to punch both legs or flanges of the angle and to cut olf the angle plates from a longer piece containing a multiple of angle plates. and to rapidly feed up thel stock and make repeated punchings and cut- -tings or shearings of successive angle plates.

Both legs or flanges of the angle plate may be punched at the same time, or only one may be punched if desired. The machine is readily arranged to operate upon angle plates of different sizes, including widely varying lengths, by reason of the clamping and punching mechanism and the'A shearing mechanism being variable or adjustable in their relative positions. The holding and releasing of the stock when a longer bar or plate is successively cut into angle plates is automatically effected and the stock automatically fed forward into position for the next punching and shearing operation. The setting and clamping of the work is automatic and-accurate. The machine also produces standard connections which are absolutely interchangeable one Way or the other. It will be understood further that the invention provides other advantages in addition to those pointed out.

The invention in its broader aspects is not limited to the constructions shown and described, but departures may bemade therefrom within the scope of the accompanying claims, without departing from the principles of the invention and without sacrificing its chief advantages. p v
