FEEDING MECHANISM FOR HYDRAULIC PRESSES.

Specification of Letters Patent. 7

Application filed October 25, 1909. Serial No. 524,467.

To all whom it may concern Be it known that I, WILLIAM P. BETTEN- DORF, a citizen of the United States, residlowing is a full, clear, and exact description.-

My invention relates to carriages or trucks for feeding heavy work to metal working machines and more particularly for feeding rolled metal beams to hydraulic presses.

The objects of my invention are to entirely avoid the expense incident to the manual handling of this kind of work; to en able the operator to manipulate the work and control the feed thereof to the press, en-

- tirely from his stat-ion alongside the machine, and to avoid the draggingback and forth-of the hose connections of the pneumatic devices used, and the rapid wearing out of the same. These and other important objects I accomplish by the means hereinafter fully described and as particularly pointed out in the claims.

In the drawings :Figure 1 is a side elevation of a hydraulic press showing my improvements used in connection therewith. Fig. 2 is an enlarged side elevation of my invention showing the central portion thereof broken away. Fig. 3 is an end view of the same. Fig. 4 is a plan view thereof. Fig. 5 is a detail view showing, in section, the pneumatic means for reciprocating the carriage. Figs. 6 and 7 are transverse vertical sections taken on line 44, Fig. 4, illustrating the positions assumed by the flipper or pneumatic device employed to turn the work. views of the grapple used in connection with said flipper. Fig. 10 is a diagrammatical view showing, in section, the pneumatic means for actuating the piston in the cylinder of the flipper. Figs. 11 and 12 are detail view's showing a side elevation, and an edge elevation of a modified construction of the grapple of the flipper.

In the drawings A represents a hydraulic press, the construction of which it is unnecessary to explain in detail. It is sufficient to call attention to the fact that it com- 'a hydraulic ram which is adapted to move downward, and, in conjunction with the Figs. 8 and 9 are detail lower die, punch, out and shape a metal I- beam according as desired. Beams of the kind shown in dotted lines in Fig. 4 of the drawings will weigh 4800 pounds. The cost of carrying this work to the press by manual labor would make the cost of the finished product prohibitive, so my invention is adapted to take the place of manual .labor and to place the manipulation of the same practically within the entire control of the operator of the press and his helper. Vith this end in view a track is laid that extends longitudinally from one end of the press, in the direction of the length of the die, and upon this track is placed a truck or carriage the travel of which away from the press is limited by the length of the air-cylinder used in moving the same longitudinally, or otherwise. This truck consists of four wheels, B, B, that are mounted on the ends of suitable axles, B, journaled in bearings depending down from, and preferably made integral with the lower ends of the sections C and D of the transverse bolsters, located at each end of the truck. Sections C, C, of said bolsters are much wider than sections D, D, and both sections have their adjacent vertical edges flanged, and, near the upper edge thereof are provided with semi-circular recesses which, when the sections are connected together form a circular openinga. for the passage of the pneumatic cylinder E, used in connection with the pneumatic *means for reciprocating the truck, as will hereinafter be more fully described. Above this opening a; the flanged edges of these sections are bolted directly to each other, but belowthe same the web of the ends of the I-beam reach, F, connecting the forward with the rear bolster of the truck is placed between the flanged edges of said section and secured thereto by the same bolts used to clamp the flanges of the lower portion of the meeting edges of said sections together. As thus secured, flanged edge of said I-beam reach enters the lower portion of opening a, and the lower flanged edges thereof arebelow the lower edges of said sections. Cylinder'E is securedto the upper flanges of the reach F by means of straps b, b, or by any other suitable means. The forward end of this cylinder terminates near the forward bolster but the rear end extends beyond the rear bolster some distance and said cylinder is provided Patented Mar. 26, 1912.

the upper with a hollow piston G, the outer forward end of which has a head 0 having longitudinally extending arms secured thereto, the extremities of which pass on each side of and are pivotally connected to lug d fastened upon and arising from the horizontal platform of a bracket 6, which latter is secured to and projects from a column f located at one end of the hydraulic press and designed, among other things, to support the adjacent overhanging end of the lower di-e, particularly when the lengths of said die are such that its ends extend beyond the end of the bed of the press.

A piston-head is secured to the inner end of the piston (gr, which latter is provided with a port 9 near said head, and is also provided with a port near its outer end, that is connected by a pipe g to a suitable source of pneumatic pressure. Extending longitudinally through piston G is a tube H, one end of which extends through the piston-head, and the opposite end of which extends out through head 0 of the outer end of the piston. The outer end of this tube H is connected by a pipe H to a suitable source of air-pressure, and pipe H and pipe g are connected to a four-way valve, I, on the end of a compressed air-supply-pipe, which is controlled by the operator alongside of the press. When it is desired to cause the truck to move toward the press, the valve is manipulated so that compressed air is admitted through port 9 into the piston, from whence it issues into the cylinder between said piston-head and its forward end, and as said piston is stationary, causes said cylinder and the truck to which it is attached to move toward the press, during which movement the air will exhaust from in front of the opposite side of the pistonhead through tube H, pipe H and its connections. When it is desired to move the truck away from the press, the compressed air is admitted into the outer end of tube H, from whence it enters the rear end of the cylinder back of the piston-head and causes said cylinder and truck to move away from the press, the air on the forward side of the piston-head exhausting from the cylinder through port 9 and out of port g The upper flanged edge of sections C and C, of the bolsters are in a horizontal plane above the cylinder opening a, and extend from the vertical meeting edges of the sec tions a distance less than one-half of the height of the web of the I-beams it is desired to manipulate, and then the edges of said sections C, O, are stepped downward to a horizontal plane intersecting cylinder E about the horizontal plane of the upper segment of the tube H.

When it is desired to place the I-beam upright, it is turned so that its web will be in a vertical plane, and its lower flanges rest.

upon the upper edges of sections C, and when it is desired to place said beam in a horizontal position, it is turned so that its web rests upon the top edges of said sections above said shoulder. In order to hold said beam in an upright position, or, in a horizontal position, according as desired, and to turn the same from the former to the latter, I have provided devices commonly known as a flipper This consists of a cylinder 2, having trunnions 3, 3, about its center of length, that are j ournaled in bearings in the outer ends of suitably shaped brackets 4, at, which latter are secured to and project laterally from the web of the reach F, just back of the forward bolsters. The position of the cylinder is such that its upper end is below the plane of the lower horizontal portion of the top edges of sections C, and it is provided with a piston, 5, whose upper end has a suitable grappling device securely mounted thereon, as will hereinafter be more fully described. The piston is provided with a piston-head on its inner end, and in order to actuate it, both the upper end and the lower end of the cylinder have a port, 6, 7, therein, respectively. A flexible pipe, 8, connects the upper port, 6, with a longitudinally disposed compressed airtube 9, and a flexible pipe 10, connects the lower port 7, with a similarly disposed com pressed-air tube 12.

Tubes

9 and 12, are, preferably, secured by means of suitable brackets to the web of the reach, and extend from end to end of the truck, through sections C. The forward ends of

tubes

9 and 12, are provided with heads having packed guide-openings for the passage therethrough of telescoping

stationary pipes

13 and 14, respectively, which latter extend longitudinally toward the press and at a convenient point are connected to a fourway valve, 11, by means of which compressedair may be supplied to one pipe, 18, and from thence to tube 9, in transit to the top of the cylinder, and the air exhausted from the opposite end of the cylinder through flexible pipe 10, tube 12, and pipe 14, or vice versa, regardless of the direction in which the truck is moving.

The grapple on the upper end of piston, 5, consists of two members, 15 and 16, each of which is pivoted at one end to a transverse bolt 17 suitably secured in the ends of corresponding ears of a boss 18 which is seend of which farthest from its pivot is provided with L-shaped or hook-shaped fingers 20 which, when the grapple is in operation, are adapted to fit over and embrace the longitudinal edges of the flangeopposite that embraced by the edge of member 15. The knuckles of the hook-shaped fingers, 20, of member 16, are connected by a transverse bolt 21, and this bolt, between the linkshaped parts of said member 16, has the eye on the end of a bolt 22 surrounding the same. The barrel of this bolt extends out through a suitable opening in the center ofmember 15, in a plane which will be parallel to the base of the beam, and has a wheel-shaped nut 23, on its screw-threaded end, 24, by tightening which the hooked ends of the said member grasps and firmly holds the adjacent flanged edge of the beam between them.v

When this grappling device has been attached to the basal flanges of the beam, and piston 5 is at the limit of its downward stroke, the said beam will be securely held in an upright position on the truck as it advances to the press, while being operated upon in said press, and while being withdrawn from the same. Of course, it will be understood that the construction of the lower die will greatly contribute toward holding the beam against any independent movement while being operated upon, but this result is greatly aided by the grapple. 1

When it is desired to turn the beam, as, for instance, when it is desired to punch or cut or shape the web thereof, the compressed air is permitted to enter the lower end of the cylinder and the piston 5 moves upward and pushes and raises the beam upward at such an angle that it tilts over onto the transverse friction roller, 30, journaled in the recess in the upper angle of the shoulder of the bolster, and assumes a horizontal position and rests upon the upper horizontal edge of section G above the shoulder, in which position,"if desired, the grapple may be removed, and an overhead crane utilized to remove the beam from the truck. If desired, the beam, when disposed upon the truck may be placed horizontally upon the upper edges G of the bolsters, in the position hereinbefore explained, and then the grapple be attached thereto and the I-beam drawn down into the vertical position.

In Figs. 11 and 12 I show a modified construction of the means carried by the upper end of the piston for grasping the lower flanges of the, I-beam. This consists of a clamping member 31 which, looking at it from the front end of the truck, is Z-shaped, and is pivoted at about its lower angle be tween the arms of the head 18 secured to the upper end of the piston. The end of the upper horizontal part of this member, 31, is flanged upward and backward to provide an inverted L-shaped flange 32, and the upper surface of its lower horizontal part is provided with a longitudinal central T- shaped tenon, 25. The other member, 26, consists simply of a straight jaw the lower edge of which is provided with a T-shaped groove that engages the T-shaped tenon, 25. In the plane of the upper surface of the upper part of member 31, member 26, is provided with a transverse groove 27, which is complementary to the channel produced by the overhanging flange 32, and is designed to embrace the longitudinal edge of theflange of the I-beam opposite that embraced by the flange 32. Member 26 is adjusted to and from member 31 by means of a screw 28, whose outer end is, preferably, provided with a hand-wheel 29 and whose barrel passes through member 26 into a tapped opening at right angles to the opposing surface of the central vertical portion of member 31.
