HYDRAULIC MACHINE FOR CLAMPING PLATES IN THE MANUFACTURE OF SPRINGS.
No. 819,872. Specification of Letters Patent. Patentea may 8, 1906.
Application filed October 4. 1905. Serial No. 281,240.
To all whom it may concern:
Be it known that I, WILLIAM EvANs, a citizen of the United States, residing at the cit of Philadel hia, in the 'county of Philadephia and late of Pennsylvania, have invented certain new and useful Improvements in H draulie Machines for Clamping Plates in the Manufacture of Springs, of which the following is a specification.
M invention has relation to a hydraulic mac line for clamping plates in the manufacture of springs, and m such connection it relates more particularly to the constructive arrangement of such a machine to so clamp and hold assembled plates as to permit of ready application of bands thereto.
The principal objects of my invention are, first, to .provide a machine with means actuated by hydraulic-pressure to force, in the manufacture of sprin the plates properly shaped and assembled against each other to securely clamp and hold the same together; second, to provide the machine with movable means adapted to support the hydraulic means and the clamped spring held by the same to permit of the moving of the clamped spring-p ates into a position so that a band can be readily applied thereto; third, to provide a trunnion with movable means provided with a chamber to form a passa e-way for water and a flexible joint, for fees-pipes, engagin the same to permit of swing ng the move le means into various angular positions and the feeding of the water under pressure into the hydraulic means, irrespective of the position occupied by the swin ing means, and, fourth to provide a mac he with a combined locking and releasing mechanism, adapted to lock the swinging frame in various angular positions in the same.
The nature and scope of my invention will be more fully understood from the following description, taken in connection with the accompanying drawings, forming part hereof, in which- Figure 1 is a view illustrating in side elevation the hydraulic spring-plate-clam ing machine, a swinging frame supported by trunnions engaging the standard of the machine, a hydraulic ram carried by the frame, a hol low trunnion adapted to form a connection between feed-pipes conducting water to and from the hydraulic cylinder actuating the ram, spring-controlled means to automatically return the ram to its normal inoperative position. and locking means adapted to hold the frame in various angular positions in the machine, all embodying the main features of my said invention. Fig. 2 is a top or lan'view of the machine shown in Fig. 1 and illustrating in dotted lines, a spring formed of plates assembled in a position so as to be clam ed by the hydraulic ram. Fig. 3 is a view ill ustrating in elevation the right-hand end of the machine shown in Fig. 1; and Fig. 4 is a cross-sectional view of the machine, illustrating in full and dotted lines the various positions of the swingim frame in the machine and the manner of holding the clamped spring-plates in a vertical position for the attachment of a band thereto.
Referrin to the drawings, Ar'epresents the standard oi the machine, consisting of frames a and a, united with each other by a plate a.
described. In the frames 0. and a are arranged bearings a and a, adapted to receive gral with a frame which by extending overbalanced and thus normally held in a substantially vertical position in the standard A, as shown in Fi s. 1 and 4. The frame I), pivotally supported in the standard A by the trunnions and b, can be swung therein,
of plates B, properly shaped into a spring B. The assembled spring -B by resting on these tables is placed with one side against a projection b, preferably formed integral with the swinging frame I), as shown in Figs. 1 and 2. Opposite the projection b", forming a jaw and sliding on the table I), is arranged forming a table for a purpose to be presently trunnions b and b preferably formed into-'- downward beyond the trunnions b and b is serve to receive and permit of the assembling to assume various angular positions with re which by means of bolts is rigidly secured the swinging frame I), as shown in Fig. l.
a h draulic rain d, preferably formed integral witTi a piston d to In addition to a gland d, rendering the piston d water-tight in the cylinder d", the same provided with a flange (1, to the extension d of which is secured a rod 0, serving as a handle, which when engaged by the operator permits of a readyturning of the swinging frame b on its trunnions b and b in. the standard A, for which purpose, however, the same must first be unlocked therefrom.
One mode of locking the swinging frame I) to the standard A and holding the same in vertical and horizontal positions therein is as follows: As shown in Fig. 1, to the under side of the swinging frame I) is secured a rod 7', which by means of a spring f is normally held in engagement with an opening f", arranged in a plate f secured to the frame a. The rod f is connected with a bell-crank leverf pivotally secured in the pointf" to the swinging frame I), and by means of a linkf is connected with the lower arm of a bellcrank leverf, pivotal] y secured in the point f to the handle 0, as shown'in Fig. 3. When the upper arm of the leverf is swung towardthe handle 2 and held in alinement with the same, the movement imparted to the lever f by means of the bell-crank leverf and link f is transmitted to the rod f, which is withdrawn from the openingf in the plate f The swinging frame I) thus unlocked from the plate f 2 may now be swung into a horizontal position, as shown by dotted lines in Fig. 4, and locked in this position by permitting the rod f, through the release of the lever f to engage the opening g, arranged in a plate {1, secured to the frame a, as shown in Fig. 4. Before, however, the swinging frame I) and the'h draulic cylinder-ram and accessories carried by the same are swung into this horizontal osition the hydraulic ram (1, actuated by tiii piston (l, must first be brought into engagement with the assembled spring-plates B. The mm d is held in its normally inoperative position preferably by rods Ii, carried by a yoke It, secured to an.
of a hydraulic cylinderd,
which at one end is secured to the swinging frame I) and at its other end to the hydraulic cylinder d*. The pipe is, terminating in the chamber i of the trunnion?) and forming the continuation of ipe l, is connected to a valve m of suitab e construction actuated by a handle m, which communicates with a source of water-supply held under pressure. (Not shown.) The ipe k by terminating in the trunnion If of the swinging frame 1) permits the same to freely turn in the stand-' ard A without in the least interfering with the proper conduct of the water into and from the hydraulic cylinder d As soon as water under )ressure is permitted to enter the cylinder (i the rain (I, actuated by the pistond, is shifted forward until the same reaches the spring B and forces the same against the jaw bof the frame I). The lates B, forming the spring B, are thus orced against each other and are then immovably' clamped in position between the jaw I) and ram (1. The movable frame bis now unlocked by the actuation of the lever f 7 and by means size, is now slip ed over the upper end of the spring, after w iich it will drop by gravity and with slight assistance, if necessary, be brought to proper position by abutting against the jaw b and ram (1. By the actuation of the valve m and the exit of the water 7 may be placed beneath the s )ring B. ()n the other hand, the spring may be returned to a horizontal position by first re turning the swinging frame I) to-its normal vertical position, in which the same, when released by the jaw b and ram (I, will again be placed on the tables a? and c of the standard A.
