' Application filed June 11, 1889. Serial No. 313,950. (No model.)

To aZZ whom it may concern:

Be it known that I, ERNEST W. NAYLOR, a citizen of the United States, and a resident of the city, county, and State of New York, have invented certain new and useful Improvements in Punching and Flanging Machines; and I do hereby declare that the following is a full, clear, and exact description of the in: vention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, in which- Figure 1 represents a side elevation of my improved machine, the dies and clampinghead being shown in section in their depressed position. Fig. 2 is a top plan of the entire machine. Figs. 3 and t show, respectively, side elevation and top plan of the machine when used for flanging sheets of large dimensions. Fig. 5 represents averti'cal section on the line a: 00 of Fig. 1, showing the female die raised and the manner of connecting the clamping-head and female die to their respective rams. Fig. 6 is a plan of the platen to which the female die is attached. Fig. 7 is a similar detached view of the female die. Fig. 8 is a section on the line y 3 of Fig. (5. Fig. 9 is a top plan of the clamping-head, showing the points of attachment of the clampingplungers. Figs. 10 and 11 show the manner of attaching the punches to the plungers when the machine is used for punching, and Figs. 12 and 13 represent detail views of the dieguide shown in Figs. 3 and 4.

My invention relates to that style of punching and Hanging machine adapted to be operated by hydraulic rams or plungers. Its object is to provide a machine of the character described which may be used either for punching or fianging, or for both punching and flanging; also, to provide a machine adapted for operating on either large or small plates.

To these ends my invention consists of one or more vertical rams for clamping the work to the anvil, and two or more vertical rams for operating the movable die, and also in a horizontal ram carrying a die or punch for finishing the turned-down edge.

It also consists in hinged standards at one end of the machine adapted to assume a horizontal position to permit of the insertion of very large sheets of metal; also, in minor details of construction and combinations of parts, which will be hereinafter more fully described, and distinctly pointed out in the speci fication and claims.

In the drawings, A represents the upper and A the lower girders of the frame, which are supported and held apart by means of four standards or pillars G G and G G, the

former of which are hinged at c e to the lower girder A and adapted to be disconnected from the upper girder, as will hereinafter more fully appear.

In order to strengthen the frame when the machine is operating on very large material the upper and lower girders A A are connected by an intermediate brace A at the end having the rigid standards. In the upper girder A are mounted three or more hydraulic cylinders O B G, placed side by side in a vertical position. In the present machine I have shown two rows of such cylinders, and on the lower girder is suitably mounted an anvil-block I-I, upon which the metal to be operated on is clamped by a clamping-head I, carried at the ends of the plungers B B of the cylinders B B. To the ends of the plungers C C O C of cylinders C CO 0, located on opposite sides of the cylinders B B is secured a platen J, to which the female die K is secured, suitable openings j being formed in said platen for the passage of the plungers B B, carrying the clamping-head I. The

clamping-head and die platen are secured to their respective plungers by means of countersunk bolts g.

In order to adapt the machine for operating upon material of large dimensionslhinge the standards G G to the lower girder at the points e e, the upper or free ends of said standards being connected by a rigid cross-head L, the upper girder A being provided with open slots or notches a forthe reception of the standards or pillars G G, the standards being screw-threaded above the girders for the reception of clamping-nuts g, by which the standards are held in place in the upper girder.

On the standards G G is a sliding cross-head M, which is capable of adjustment thereon by means of a screw F, journaled in the rigid cross-head L and having collars Z Z to prevent longitudinal movement of the screw. A block N, carrying a centering-pin a, is mounted in a guideway in the adjustable cross-head M, and is laterally adjustable therein by means of a screw E, secured at its ends in said crosshead. In order to finish the flange either by corrugating or punching I provide ahydraulic ram D on the lower girder, the plunger of which carries at its end a punch or other finishing-tool D, secured thereto, as shown in Figs. and 11.

In Figs. 3 and 4, Ihave shown my improved machine as operating on large sheets having a regular curve, in which case it is desired to flange only one edge. In this case I prefer to dispense with the plungers C G, as shown, and secure the clamping-head to only one of the plungers B and the die to the remaining plunger B, a guide-bracket 0 being used for guiding the die K, as shown in Figs. 3 and 4.

The operation of the machine is as follows: Assuming that it is desired to flange a sheet of metal on all. sides of a shape corresponding to that shown in Fig. 6, the proper die and clamping-head are secured to the plunger, and the anvil-block H of the desired form is secured to the girder. The metal to be operated on is placed on the anvil-block and the clamping-heads descend upon it. The platen and die K then descend upon the projecting edge and bends the same, when the clampinghead-and die are again raised.

When it is desired to flange or bend a large plate which could not otherwise be operated upon except in a press of very large size, the nuts on top of pillars G G are loosened, and the pillars are then lowered down into suitable adjustable stands or rests P into either a horizontal or angularposition, thus leaving one end of the press entirely free and open, and any sized plate can then be inserted and operated upon.

If it is desired to produce a flange of regular curve and of large radius, then the plate is centered or attached to the centering-pin on sliding cross-head M, which is moved in one direction by the screw F and in a direction at a right angle thereto by a similar screw E on the slide itself. The plate can then be adjusted as to distance from the die and true radius found either at one or more heats, accordingly as the flange desired is large or small, and if the desired flange takes an irregular curve the distance may be varied at will to form the curves as desired. A number of holes may be punched either ina circle or straight line by this device, either in the flange by the ram D or on the body of the plate by the vertical rams, by simplyremoving the forming-dies and attaching a punch or punches to the plungers, as shown in Figs.

10 and 11. Where only a single flange is desired or a flange on one side only, I prefer to secure the clamping-head to only one plunger B and the die to the remaining plunger B, in which case I make use of avertical guide 0 for the die K, an opening Q being left in the lower portion of said guide for the passage of the plunger of ram.

While I have shown and described the die as operated on by four plungers and the clamping-head by two,I do not wish to be confined thereto, as more or less may be used for each without departing from the principle of my invention. The object of the rain D is to square up, corrugate, indent, or otherwise operate on the plates or sheets while held by any of the vertical rams.

Having described my invention, what I claim,and desire to secure byLetters Patent, 1s-

1. A metal-forming machine having rams provided at their ends with devices to act upon the metal and having hinged pillars arranged to engage the cross-head in which the rams are mounted, substantially as and for the purpose described.

2. In a metal-forming machine, the combination, with power-actuated dies for forming the metal, of two hinged pillars adapted to assume substantiallya horizontal position, an adjustable cross-head on said pillars, and a centering-pin adjustable on said cross-head, substantially as and for the purposes described.

3. The combination, ina metal-forming machine, of the movable and stationary dies, an adjustable cross-head carrying an adjustable centering-pin, and arms pivoted at one end to said centering-pin and adapted to be connected at their other ends with metal to be operated on, whereby said metal may be moved about a given center, substantially as and for the purposes described.

4. In a metal-forming machine, the combination, with the frame composed of upper and lower girders rigidly connected together .at one end, of pillars hinged to' the opposite end of the lower girder and adapted to engage open slots in the upper girder, and clampingnuts on said pillars, substantially as and for the purposes described.

In testimony that I claim the foregoing improvement in punching and fianging machines as above described I have hereunto set my hand this 7th day of June, 1889.
