The valve is operated through a valve-lever K and pivotally supported on a link K, as shown in Figs. 1 and 5.
L is a supporting-frame having extending from one side of it the annular ring L, which is centrally divided, as indicated at Z, by a cut extending throughits base and nearly, but not quite, to its top, the base being provided with the perforated lugs L L through which passes a clamping-bolt M. (Indicated in Fig. 1.)
Extending in opposite directions from the frame L are the trunnions L L, the trunnion L having a central longitudinally-extending perforation (indicated at L opening laterally through ports L, the central perforation communicating with a lateral port L, which extends through a threaded projection L, L indicating a plug to close the end of the longitudinal perforation. The trunnion L is similarly provided with ports, the longitudinal port being indicated at Z the lateral ports at Z, and the longitudinal port ending in a chamber Z, from which extends a port L opening at the top of the ring L through a slightly-projecting annular extension, (indicated at L.) The bails E and I connect to common coupling-bases with annular bearings N, which lit on the trunnions L and L, and are provided with annular chambers (indicated at N which communicate through the ports L and Z" with the ports L i, N indicating a gland by which the packing in the chamber N is secured in place.
0 is a cylinder secured to the ring L of the frame L by a downwardly-extending annular flange O, O indicating the straight cylindrical part of the cylinder-chamber and O packing-rings secured in the downwardlyextending annular portion 0 by a gland O.
P indicates the top or head of the cylinder, from the center of which depends the downwardly-extending tool-holding device P; P indicating an outwardly-extending annular shoulder near the upper end of the device P, P a port or passage extending longitudinally from the top of the tool-holder P, and P a tube passing from side to side through the tool-holder P and having central ports P, which communicate with the port P. The lower end of the tool-holder, as shown, has an internally-threaded orifice P, into which screws the head P, to which the punch (indicated at P and having a central linger or point P") is connected by means of the coupling device indicated at P.
Q indicates a perforated head screwing into the top of the part P and coupled by a union Q, with a pipe Qf, which in turn communicates with the threaded projection L of the frame and through it with the ports L U L and tubular bail E.
R indicates the piston working in the cylinder O and having an upwardly-extending cylindrical extension R, which makes a workingfit with the annular shoulder P of the tool-holder P and forms a cylindrical chamber r between the outwardly-extending shoulder P of the tool-holder and the inwardlyextending shoulder R of the piston.
R is a sleeve extension depending from the bottom of the piston and working between the cylindrical tool-holder P and the packingrings held in place by the depending annular extension O of the cylinder.
S is a tool-holder for the lower tool or die, which is secured to the lower portion of the sleeve R", having, as shown, a split ring at its ends, terminating in flanges S S, which are clamped together by bolts S The toolholder is shaped to give convenient passage to the work below the punch 01' tool P and has a portion S adapted to hold and support the tool or die S beneath the upper tool.
R is a ring screwing .on the end of the sleeve R below the split ring of the toolholder S and provided with stripping-fingers R R, which when the piston R is in its lowest position extend below the punch P, as shown in Fig. 3.
T, Fig. 3, indicates a spring which, as shown,
has for its chief function the holding in proper I place of'the cupped leathers at the top and bottom of the cylindrical chamber r. To the extent of its strength it is obvious that the spring will also operate to push down the piston R and its connected parts, and this is menthe port 0 into the chamber B of the head B and through the ports B to the ports B and B The fluid constantly fills the thimble D and bail E, communicating from said bail through the ports L, L and L and the conduit Q and head Q, withthe longitudinal port P of the upper tool-holder, from said port passing through the lateral-ports P of'the tube I into said tube and through it into the cylindrical chamber r, where it acts on the lower shoulder R formed in the piston, pushing said piston and parts depending thereon, downward to their lowest position, or as shown in Fig. 3. From the other port B connected with the .port B pressure fluid passes to the port D, and thence to the port H of the valve casing H, and thence, the valve being in the position shown'in Fig. 5, the fluid passes up inside of the flange J of the cylindrical portion J and out through the lateral ports J into'the port H and thence, through the tubular bail I, to the ports'in the trunnion L, and thence throughthe port L to the cylinder 0, which is coupled therewith, as shown, by athimble 0, Fig. 2. The pressure fluid acting on the piston R raises it and its sleeve R the said sleeve carrying upward the tool holder S, and stripping-fingers R and brings the tools S and P into operation upon the plate, which, of course, is situated between them. When the work is effected, the valve J is moved upward, the portion J cutting off the supply of pressure fluid and the cylindrical portion J 2 moving-upward in the annular ring H until the lateral portsJ open on the upper side of said ring, when the fluid from the cylinder is free to flow backward through the bail I, port H ports J and ports H into the port H of the casing, whence it passes through the ports D and B to the exhaust-pipe G. The weight of the parts depending on the piston will of course tend to draw the piston down, the resistance of the work or from other sources being overcome by the constant fluid-pressure in the cylinder 9*, which thus acts as a pull-back cylinder.
The stripping-fingers R R press against the work asthe piston R and sleeve R move down and press it off the punch P Having now described the said invention,
