residing in the city and county' of v invent certain new and useful Improvementsgin Punc hing-Machines, of which the follow- .a true and exact description, reference had to the; accompanying (fi'awings, =forfn a part thereof. 7

The invention relates 'to punching machines, and has especially in view punchingmachines such as are used to punch the rivetholes .in' ship-plates, though in many of its features it is adapted'for more general use.

-The object of the invention 1s to provide a punching-machine which can be readily shifted with-reference to the Work, so as to The invention ment of the u of the punch to operate upon a considerable area of the plates I without requiring them to be moved.

has also in view the attain.- tmost nicety in the adjustment the position of the ndicated hole to be formed in the j With these general-objects in view the 1n- .ventions-consists, in the first place, in'the various devices for movingandadjusting the .m a device by -ma chine in a horizontal plane; also,


which the plate. isslightly raised above the die at all times except when working stroke of actually under the pressure of the punch, so

' as to permit free movement of the machine ment of the punch to be made before it actuallyperforms its ofiice, and, finally, in various improved devices andcombinations of devices by which the operation of the machine "is rendered largely automaticand bywhi'ch with the pit in which it works seethe control of the operator l made simple stood as described in connection with the drawings in which the-inventionis illustrated, and in which Figure 1s a side elevation of the machine Ema-comma; or CAMDEN, NEW

Q is a pipe leading from they port 0 of the valve-casing to exhaust.

The mode of operation of the valve-actuating mechanism described is such that after the working stroke of the punch is finished and the punch and its actuating-piston have reached their lowest point the valve is shifted to exhaust, as shown, for instance, in Fig. 29, and the full pressure being constantly main tained in the pull-back cylinder L the cylinder and the punch'depending from it are drawn upward by the action of the .piston L to the top, at which oint the valve is automatically shifted to t e'position shown in moves downward until t Fig. 28, cutting off the exhaust and connect= ing the pressure-fluid supply with-the cylinder H". The piston carrying the punch then e unch is brought to the. position shown in Fig. 14, when the valve is shifted to the position shown in Fi 17:, cuttingrofl the supply of pressure fluid,

but not oplen'ing the exhaust, so that the pise punch remain in fixed position,

-- Referring'now to the mechanism as shown in Figs. 17 to -21, it wi'lLbe seen that the mo-' abutment t-lock N ofthe leverjN which is directly attached to theval've-ro'd', and con .sequentl'y it wiH be-seen that the downward movement of the piston carrying the-punch communicates an outward movement to both Ithe slidesN and N a'nd that 'the'outward .-movements'.of the lastfementionedslide effects a shifting of the valve from 'the position shown in Fig. 28 to-the position shown in Fig. 17, in whichlastnientioned' position the pressure fluid is out Off from 1 the actuating cylinder and thegpistdns and unchbrought toj-a rest in the position in cated, for in.

stance, in Fig. 14;. During the movements of the rods above described the spring-su porting head N is engaged by the catchever N as shown in Fig. 20, the other head n resting on the 0nd of, but not engaged by, the catch-lever n and abutting against the abutment-block N secured on the slide N This block of course moves outward as-the rod N- is moved outward, carrying with it 1 the spring-head n and pressing the spring N between said head and the stationary head N the spring-pressure thus acting in opposition to the movement of the rod N, which shifts the valve to the cut-off position;

The parts being in. the position above described, the operator controlling the lever G, having brought the punching-machine to correct position with reference to the plate by manipulating said lever as already de-. scribed, presses down the rod Gr until the circuit-wires G G are connected through the contacts G11 Gr and an electric current established through the. solenoid-coil 'R,v

supported on the bracket 1" The coil being thus energized draws down the core R with great energy and impinges the rod R on the end n of the lever N n overcoming the force of the spring N and forcing the latch 'N upward until it disengages the abutmentvblock N and frees the lever N from connec-- tionwith the rod N. The spring N acting through the head N and the abutmentblock N then forces the rod N inward, drawing the valve to the position shown in Fig: 8,'whereupon the pressure fluid again I flows to the actuating-cylinder and the piston and Ipunch moved downward, completin the wor ing stroke During this downwar movement of the-piston the rod N continues its interrupted outward movement, its abut ment-blo'ck N coming in contact with the sprin .-head N and compressing the sprin N, t e other end of which is still held fixe by the head N The movement of the head n finally brin s its arm a into contact with the shoulder o' the slide N forcing this slide outward so that its outer finger N presses I against the bottom shoulder of the catchlever N forcing its catch-arm downward 1 until it releases the spring-head-N, where- I upon the force of the spring N 'is exerted through said head ageinst the I abutment? block N", forcing saidlock and the rodN its outward by a rapidmovement, so as to bring the valve to the position shown-in-Fign29,

cutting'off the pressure fluid-and opening'the actuating-cylinder to the exhaust, whreupon the pull-back cylinder: L11 draws up- 7 ward the actuating-piston and punch; but before the working stroke is completedtlie outward motioh of the abutmentblock N.

has forced the head a" into a position where it is engaged by the catch-lever n j 7 During theupward movement of the pistonthe-ro-d N is of course moved inward, its abutmentagainst the spring-head block N passing under the. lever N and the latch N until said latch is engaged with the under side thereof, as shown in-Fig. 20, and said abutment-block N pressing against the spring-head N n, held stationary by the catch-arm n. This compression-of the spring'continues until its arm N comes in contact with the head N? and shiftsit in the direction of the catch-lever n, whereupon its finger n head a, which is forced rapidly backward, carrying with it the abutment-block N' iand the rod N and shifting the valve to the posi-.

tion shown. inFig. 28, again admitting pressure to the actuatingecylinder, which moves down-to the point of automatic arrest, as al ready described. l v

It will be:understood from what has been said that the IHOtl O'IIS of the rod N under the 'infl'uenceof the spring N are'made with great rapidity, and therefore there are provided the abutment-springs N and In to cushion its movements in opposite directions;

The apparatus illustrated and above d e scribed 1s thatwvhich has been devised and developed as best adapted for the purposes described. .It will, however, be obvious that v the actuating mechanism can b'e-modified very considerably without departure from the inventiomand this should be clearly understood as in no wise limiting-the invention upon the details of construction illustrated, except-where such details of construc-- tion are expressly referred to and specifically transvers portedion ade part ofthe combinations covered by the claims.
