STEAM-HAMMER FOR FORGING STEEL WHEELS.

SPECIFICATION forming part of Letters Patent No 414,030, dated October 29, 1889.

Application filed May 8, 1889. Serial No. 310,026. (No model.)

To all whom it may concern:

Be it known that I, JAMES A. FACER, of Philadelphia, Philadelphia county, Pennsylvania, have invented an Improvement in Steam-Hannncrs for Forging Steel Wheels, of which the following is a specification.

My invention relates to steam-hammers for forging wheels for cars, &c.; and .it consists of certain improvements, which are fully set forth in the following specification and shown in the accompanying drawings, which form a part thereof.

More particularly my invention relates to certain improvements in the hammer and anvil dies of the stean1-hammer for forging the ingot into the requisite shape.

Heretofore it has been customary to manufacture car-wheels by two processes, one of which consists in first casting the wheel of approiziinately the shape of the finished article and then subjecting the casting to a rolling action in a machine especially adapted to the purpose, and the other of which consists in casting the center of iron or steel and fitting thereto a steel tire, which is forged into shape from a solid bloom by proper manipulat-ion under a steam-hammer and rolls. These processes have many objections, principally in the matter of expense or cost of manufacture, and in the case of the first-mentioned process a lack of homogeneity and solidityin the cast metal of the finished wheel.

The object of my invention is to make a car-wheel formed from a solid ingotrbloom of steel by forging the ingot under heavy steamhammers having suitably-shaped dies. The car-wheel made in this manner is compact and homogeneous as to metal and possesses a hardened surface, due to the forging process.

In carrying out my invention I first take a heated bloom orsteel ingot and place it under a steam-hammer having dies of the proper shape to first flatten out the bloom into a disk of sufficient diameter to form the wheel. Then this is done, the disk, still in its heated condition, is set on edge and rounded up, and at the same time the flange or treading part of the wheel is finished in rough. Then the bloom is shaped as above indicated, it is placed flat upon the anvil-die and a punch is used to form the axle-holes. The hammerdie in this operation is used to drive the punch into the metal. This punched bloom or rough wheel may then be forged into the finished wheel by suitable hammer and anvil dies, with which, however, the present invention is not concerned, as they form subjectmatter of another application, filed on the 8th day of May, 1889, and serially numbered 310,025.

The present invention is concerned only with the devices for flattening, rounding up, flanging, and punching the bloom in the manner described, whereby all of these operations may be performed on the same hammer and with one heating.

I do not claim in this application the process of manufacturing wheels herein described, as that forms the subject-matter of my application, Serial No. 310,027, filed May 8, 1889.

I11 the drawings, Figure 1 is a front elevation of a steannhammer embodying the prin ciples of my invention. Fig. 2 is a sectional side elevation of the same on the line XXof Fig. 1. Fig. 3 is a perspective View of the detached hammer and anvil dies, and Fig. 4.

is a general view of the various shapes given to the bloom in the different stages of its construction.

A is the hammer.

B is the anvil-die, having a flat surface I) and formed with a laterally-projecting base supporting part E, preferably curved,having a groove e corresponding to the section of the flange of the wheel. The parts E e are arranged at the front part of the body of the anvil-die and at a considerably lower elevation than the upper surface I), so that the front vertical surface L will act as a support for the bloom during the fianging operation. This anvil-die is also provided with a lateral support F, having a groove f for the flange of the wheel. A pin G is detachably secured to the lower part of the anvil-die and acts as a support for holding the bloom in a vertical position while being trimmed.

O is the hammer-die, which is formed with a flat face 0, corresponding in size With the surface I) of the anvil-die, the line of action of the hammer-rod being preferably through the central point of these surfaces 0 and b. The hammer-die is provided with a projec tion D on its front part, having the under groove 6 of the anvil-die.

curved surface D and groove cl therein corresponding with the curved surface E and It is apparent that the projection D may be of any size and may extend the entire length of the die 0. The surfaceD is raised slightly above the surface 0, and the surface F is lowered below the surface I), so that the surfaces 0 and Z) may be used to good effect in working down the bloom during the flattening process from the shape No. 1 in Fig. 5 to shape No. 2. v

The curvature of the surfaces E and I) may be dispensed with, if desired, for, while they have a tendency to center the blank under the projection D, they cannot correspond to the curvatures of wheels of different diameters.

The surfaces 0 and b are preferably made long and narrow, and the parts E and D are arranged at the middles of the dies, and as closely to the center line of the piston-rod of the hammer as possible, to reduce the leverage as far as possible, and thereby prevent undue strain upon the dies and hammer.

\Vhile I prefer the details of construction which are here shown, I do not limit my invention thereto, as it is apparent that they may be varied in many ways without departing in the least from the principles of my invent-ion.

The operation of my improved hammer is as'follows: The heated ingot 1 of Fig. 4 is placed upon the surface of the anvil-die and flattened down into the shape 2. It is apparent that any shape of ingot may be used, though that shown is preferred. This flattened blank 2 is then placed against the face L of the anvil-die and rests upon the surface E and over the groove 2, as shown in dotted lines in Fig. 1. The hammer-die O is now brought down, and by the hammering operation and turning of the bloom the flange is formed upon the bloom, bringing it into the shape 3 by reason of the forging operation between the surfaces E e D cl, which gives to the edge of the bloom a shape corresponding to the cross-section of those surfaces. The bloom is now placed flat upon the anvil-die surface I) and a punch driven in by the hammer. -The bloom is then turned over and the punch is driven from the other side to form the axlehole K. The blank will then be flanged, rounded up, and punched in the condition shown in Fig. 4.

It is apparent that the punching operation may be performed previously to the rounding up and flanging, if desired; or the hole may be subsequently drilled.

Having now described my invention, what I claim as new, and wish to secure by Letters Patent, is

1. In a steam-hammer for forging wheels, a hammer-die having a projection upon one face thereof, in combination with an anvil die provided with a laterally-extending support for the periphery or tread of the Wheelblank to hold said blank in an upright position against the side or face of the anvil and permit it to be turned during the rounding-up and hanging operation.
