UNITED STATES PATENT OFFICE.
ROBERT C. MANVILLE, OF VATERBURY, CONNECTICUT.
DOUBLE-ACTION PRESS.
SPECIFICATION forming part of Letters Patent N 0. 460,322, dated September 29, 1891. Application filed April 8, 1890. Serial No. 347,056. (No model.)
To all whom, it may concern: 7
Be it known that I, ROBERT C. MANVILLE, of Vaterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Double- Action Presses, of which the following is a full, clear, and exact description, whereby any one skilled in the art can make and use the same.
The object of my invention is to provide a shaping-press of aconstruction with the guide or carrier block so connected to the main shaft as to provide for the adjustment of the guide and for its operation in a manner that shall obviate any chance of tipping or tilting the guide; and to this end my invention consists in details of the several parts making up the machine as a whole, and in their construction and combination, as more particularly hereinafter described, and pointed outin the claim.
Referring to the drawings, Figure 1 is a detail front view of the upper part of a doubleaction press, with parts cut away in vertical central section. Fig. 2 is a view in cross-section through the driving-cam and guide. Fig. 3 is a detail perspective view of the yoke. Fig. 4 is a detail perspective view of the guide or carrier block. Fig. 5 is a detail view in elevation, with parts out in section, of a crank-press embodying my improvements. Fig. 6 is a detail View in cross-section through the guide or carrier block and driving-shaft of the machine shown in Fig. 5. Fig. 7 is a detail perspective view of the guide or carrier block; Fig. 8, transverse section through the gate-cutting 011 line as a: of Fig. 1, looking downward.
In the accompanying drawings, the letter a denotes the body of the press, that maybe of any convenient outline and size; I), the frame, usually oblong and with upright side parts provided with guides for the gate; 0, the main shaft, that is mounted in suitable bearings transversely of the frame and provided with a driving pulley or wheel 0, by means of which the shaft may be rotated. This shaft 0 is provided with a cam c and cranks 0 the former being used to drive the main portion of the press and the latter connected up with a yoke that supportsthe drivingthrough punch. In place of the cam the equivalent form of crank may be employed, as illustrated in Figs. 5 and (3 of the drawings.
The slide or gate (1 is connected to the shaft by means of the connecting-rod e, and is mounted between the side parts of the frame or guides on runways that are provided on the inner sides of the uprights in such manner as to admit of a vertical sliding movement of the gate on its supports, and in the form of gate shown in Fig. 1 the connectingrod passes through an opening or socket in the center of the upper part of the gate, in which it is held against rotation by means of a spline or key at, that is clearly shown in the perspective view in Fig. 4 of the drawings.
The connecting-rod e is threaded and provided with a pair of jam-nuts e 6 above and below the cross-bar of the slide or gate through which the rod 6 passes. The gate has its central portion cut away so as to give room for the yoke and connecting-rods that form part of the drawing-through-punch mechan ism and enables the drawing-through punch to be located in the axial center of the gate and directly below the main cam or crank. This forms a connection that is central of the gate and provides for as fine an adjustment of the slide as may be required, the central location of 'the connecting parts and the means of adjustment preventing any tipping or tilting of the gate in the operation of the parts.
The construction of the gate and the combination of the cross-head therewith are illustrated in Fig. 8 on an enlarged scale. The cutting away of the central portion of the gate forms a chamber within which the cross-head g may work up and down. The length of this recess corresponds substantially to the extreme length of the cross-head, and on the front or one side of the gate gibs or side pieces m are applied, which overlap the chamber thus formed in the cross-head, and, as clearly seen in Fig. 8, these gibs are attached by means of screws, as seen in Fig. 4, or otherwise, so as to be readily removable, to open the chamber. The portions n n of the cross-head each side of the center are of a width corresponding to the width between the inside of the gibbs m and the corresponding opposite sides of the chamber in the gate, and so that these portions of the cross-head may work up and down between the said gibs and the corresponding opposite sides of the chamber in the cross-head rods, may take a bearing on their respective sides of the chamber, so as to guide the crosshead laterally. Thus the cross-head is guided to prevent its longitudinal or lateral movement, and also to prevent its forward and back movement. It is thus held firmly, yet free to be moved up and down in the gate in the operation of the press. The openings 19 p in the upper end of the gate, and which extend into the cross-head chamber, are elongated, as shown in Fig. 4, so as to permit the swinging movement of the rods g in the operation of the press. The connection between the gate and the shaft being central and the connections between the shaft and the crosshead being at each side of this central connection of the gate permits this arrangement of the cross-head, whereby it may stand in an actual central position and be firmly guided and operated.
The die-block f is secured to the lower face of the slide in any convenient manner, as by a dovetailed joint and a key or Wedge. On opposite sides of the central main cam c the yoke g is connected to the crank on the shaft 0, the side rods g passing through openings 19 in the gate (1 and pivotally connected within the latter to the cross-head g, to the center of which is adjustably connected the punch h or its spindle. The spindle of the punch is threaded, and nuts h h", borne on it above and below the cross-head, serve as means of adjustment, so that the location of the path of movement of the punch may be accurately determined.
In Fig. 5 the press is shown with the connect-ing-rod e secured to the gate by a slightlydiiterent although equivalent means of con- .nection to that shown in Figs. 1 and 20f the drawings. In the former a cam is used to drive the main press, and the connecting means consist of a yoke, (shown in Fig. 2,) the cross-bars of the yoke Zbearing anti-friction rollers Z in a line with the center of the connecting-rod and path of movement of the gate. The cross-bars are connected by bolts provided with means of adjustment for taking up any wear between the parts.
In Fig. 5 the gate is shown as connected by the rod 6 to a crank by an ordinary strap device, and the adjustingmeans are located between the crank and the point of pivotal connection between the rod e and the gate d.
I claim as my invention In a double-acting press, the gate arranged in suitable guides in the frame, combined with a vertical central connection between the gate and the driving-shaft, whereby vertical reciprocat-i-ng movement is imparted to the said gate, the gate constructed with a' vertical cen-.
tral recess therein, forming a chamber open to one side of the gate, that side of the gate provided with removable gibs, a cross-head arranged in said chamber, the said gibs and the opposite sides of the chamber forming guides for the vertical reciprocating movement of said cross-head, the cross-head constructed with trunnions at each end, the upper end of the gate constructed with open-' ings corresponding in position substantially to the said trunnions, connecting-rods lhung by their upper end to corresponding cranks on the driving-shaft and extending through the said openings in the upper end of the gate down to and hung upon said trunnions of the cross-head, the said cross-head adapted to carry the punch working through the lower end of the gate, substantially as described.
