CONTROLLING DEVICE FOR PUNCHES.

SPECIFICATION forming part of Letters Patent No. 772,826, dated October 18, 1904.

l Application filed December 22, 1903. Serial No. 186,175. (No model.)

To all whom, it may concern:

Be it known that we, J oHN'V. W. REYN- DERS and WILLARD T. SEARs, citizens of the United States, and residents of the city of Harrisburg, Dauphin county, Pennsylvania, haveinvented certain Improvements in Controlling Devices for Punches, of which the following is a specification;

This invention consists in a novel combination of apparatus for controlling the action of any desired number of punches in a punching-machine, one object of the invention being to provide mechanism which shall automatically cause the operation of a punch or punches so constructed as to be normally inactive and also to provide means whereby the operation of the punch or punches or the prevention of such operation will be made tooccur at predetermined intervals. It is further desired to provide means whereby any number of punches may besi multaneously caused to operate, it being desired to employ our improved mechanism in connection with an automatically-operated spacing-table in such manner that as said table is intermittently moved a single punch may be made to operate so as to form holes in a plate at any desired intervals or if a number of punches be employed to operate upon the same plate to so actuate the punch-controlling mechanism that its punches will be made to act at any desired intervals and i any desired combination.

These objects we attain as hereinafter set forth, reference being had to the accompanying drawings, in which- Figure 1 is an end elevation of a portion of aspacing-table for a punching-machine, showing our improved apparatus as applied thereto. Fig. 2 is a plan view of a part of the device shown in Fig. 1. Fig. '3 is a sectional elevation of a portion of a punch, showing our improveddevice applied thereto for controllingits'action. Fig. 4 is a plan view of the mechanism shown in Fig. 3. Fig. 5 is a side elevation of the mechanism for intermittently turning the templet-carrying wheel. Fig. 6 is a diagrammatic view of the pre- 1903, Serial No. 186, 25.

ferred arrangementof. electrical connections employed in carrying out our invention.

Fig. 7 is a plan view, partially in section,

showing the preferred arrangement of theparts of a spacing-table with which our invention may be used; and Fig. 8 is asectional elevation of the stroke-controlling cylinder and its attached parts.

In the above drawings the invention is illustrated as employed in connection with an improved form of automatically operated spacing-table, which will not be described in detail or claimed in the present application, as this has been done in an application for patent'filed by us under date of December 26, i

It may, however, be stated that a plate of material to be operated upon is supported so as to be connected to and movable with a carriage whose framework is shown at A, which carriage is supported on a series of tracks a and a carried by suitably-placed standards, of whichjone is illustrated at B. l

A- driving-shaft b or othersource of motive power is so connected to the mechanism of the punching machinewith which thewhole structure is employed as to be given a certain amount of rotation or movementat each operation of said machine, and this source of power by means of suitable gearing is made to reciprocate a rod 0 once for each stroke of the punch. Said gearing in the present case includes a chain 6", connectingv suitable sprocket-wheels on the shaft b and on a shaft 6 bevel gear-wheels respectively fixed to shafts b and 12*, a cam 6 fixed to the shaft 6, and-a lever Z2 pinned to the rod 0 and having a roller (not shown) which follows the camgroove on said cam'b Said rod 0 has upon it a piston 0 which operates within the cylinder C and while being supported so as to .be movable relatively to the carriage is made such motion of the carriage, or, what is the same thing, the length of the stroke of the cylinder, is, as described in our above-mentioned application, determined by a series of stop-plates, of which two are shown at (Z and 5 d, these being supported so as to be successivel y made to engage a valve-rod c, by which a valve 0 is controlled so as to permit the flow of fluid in the cylinder C to take place from one side of the piston to the other. It will be understood that the stop-plates of the various lengths required are supported in a substantially rigid manner upon the carriage, so that whenever the piece 0' carried by the valverod of the cylinder C, strikes oneof them mo- 5 tion of said cylinderimmediatelyceases, since the piston within it is then free to force the liquid from one end of the cylinder to the other through the opened valve. On the return stroke the valve 0 being free to move on its stem, immediately closes and the cyl- 5 which has a valve similar to the valve 0,

strikes a portion of said table, and thereby opens said second valve, thus permitting liquid to again pass from one end of the cylinder to the other end, so that the device is 3 ready to make another stroke. The stopplates are carried in the present instance upon atemplet-wheel D, which'is shown as grooved for their reception, and there is fixed to the same shaft as said templetwheel a wormwheel d which is intermittently turned to the extent of the angle between each stopplate by means of any desired mechanism. For this purpose we have shown a drivingshaft 0 connected in any desired manner to 40 the main shaft 6 and provided with a cam e,

which oscillates a lever 0 suitably provided with a roller in engagement therewith. This lever carries a pawl a in engagement with a ratchet-wheel e, and this latter is keyed to the same spindle to which is fixed a bevelgear 6. A pinion 0 meshing with this gear, operates a worm a in engagement with the worm-wheel (Z through the medium of a shaft 6, and by this means it will be seen that the templet-wheel D, with its stop-plates, will be moved forward to the desired extent upon each revolution of the driving-shaft e. The templet-wheel is so supported upon its shaft that either it or said shaft is free to move longitudinally, or, if desired, the stop-plates may be so fixed to said wheel as to move to a limited extent when engaged by the valverod 0, and it will be seen by reference to Figs. 2 and 6 that the rear edge of each of the stop-plates is provided with any desired number of projections (Z for purposes hereinafter set forth.

Referring now to Figs. 3 and 4, we have illustrated a punch and a portion of its ad jacent parts arranged for operation according ,f'is free to pass.

to our invention, and it will be understood that any desired numberof these punches may be supported upon the plunger of a punchingmachine so as to be capable of forming a plurality of holes in a suitably-placed sheet of material when said plunger is thipressed. In Fig. 3, F is the punch-holding piece, which is bolted or otherwise suitably attached to the face of the plunger of the punchinganachine in the well-known manner, and in this piece is a cavity into which the punch-earning head To this head is secured a punch f" by means of a nutf, and there is a horizontally-n1ovable slotted block 7 so placed as to be free to be moved over the end of said punch-head and between it and the face of the plunger. The position of the block f depends upon whether or not a solenoid f is energized, for this latter is carried at one side of the punch F and has an armaturcf fixed to the said sliding block. Av springf normally tends to hold the armature, and consequently the bloekf, in such position that the punch will not act to make a hole in a piece of material, but will simply move upward when the plunger carrying it is lowered. \Vhen, however, the magnetj is energized, said block is made to slide into position over the upper end of the mneh-head f, with the result that when the plunger of the machine makes a stroke the punch f will be forced through any material in the proper position relatively thereto. In order that the magnets f" of one or more of the punches may be properly energized, so as to cause operation of said punches, when desired, we connect them, as shown in Fig. 6, one terminal of all of the magnets being in electrical connection with a terminal of the currentgenerator G, and the remaining terminals being connected, respectively, to trolley-wires supported in any desired manner upon the supporting-standards 13 for the weak-holding carriage, so as to be engaged by trolley-wheels 1, carried upon a piece of insulating material 1. These wheels are connected, respectively, to one terminal, of switches supported upon a standard of the carriage, and all of the terminals of said switches are connected together by a wire attached to a contact-piece g, carried by the cylinder (J, but insulated therefrom. A fixed contact 1 is supported in a suitable position upon the work-holding carriage so as to engage the contact under certain conditions of operation, and is in turn electrically connected to a trolley-wheel so placed as to engage a trolley-wire in connection with a second terminal of the curre11tgenerator Gr.

Preparatory to starting our improved machine a series of stop-plates similar to u and (Z is fastened to the ten'iplet-wheel l) in such positions that as said wheel is turned their rear ends, which are provided with the projections (P, will move in a plane close to the contacts of the switches carried by the standard g on the carriage. When now the device is set in operation, each time the valve-rod of some of the, switches, and since said pro-- jections on the stop-plates bridge the terminals of said switches certain of the magnets f will be energized as soon as the cylinder has been moved sufficiently to cause the contact g to engage the contact 9 If the punch- "plunger be now reciprocated, those punches whose magnets have been engaged will be caused to make holes in the plate operated upon, while the others will simply slide up ward in said plunger without acting.

The construction of the ratchet mechanism is shown in Fig. 5, and after each operation of the punch it will move forward the tem' plet-wheel, so as to bring another stop-plate in line with the switches on the standards 9 .and with the valve-rod c onthe cylinder.

From the above it will be understood that by our improved device any desired series or arrangement of holes may be punched in a sheet operated upon and that without requiring the presence of an attendant. After the stop-plates have once been fixed to the templet-wheel and the plate to be operated upon has been properly fixed relatively to the carriage it is only necessary to start the machine,

employ some form of electrical device as a connection between the carriage and the punch, the actual power for moving the gag could be obtained from any fluid under pressure, the flow of such fluid being controlled by magnets. If desired, the movement'of the punch-head itself could be utilized to move the gags,-the means by which this was accomplished being rendered operative through the agency of electrical apparatus.
