APPARATUS FOR FORGING METAL.
SPECIFICATION forming part of Letters Patent No. 239,245, dated March 22, 1881.,
Application filed December 30, 1880.
Be it known that I, WILLIAM B. HAYDEN, a citizen of the United States, residing at Golumbus, in the county of Franklin and State of Ohio, have invented new and useful Improvements in Apparatus for Forging Metals, of which the following is a specification.
Thisi nvention relates to machines forforgi n g metals into irregular forms, its object being to providea machine havinga rolling action upon the metal capable of. being controlled by a single workman; to so construct the machine that the metal blanks may be-con venientl y and acc rately placed in position for the action of the dies or passes, and that the necessary adjustments forsuccessive actions upon the metal may be facilitated.
The invention consists, mainly, in the combination, in a metal-forging machine, with a continuously-revolving die, of a vibratory beddie arranged to co-operate therewith to produce a rolling or drawing action upon metal,
and provided with means for automatically returning the vibratory die, after the completion of a pass, to its normal position independently of the movement of the rotary die, and holding it there for an interval of time before the revolving die again reaches a position X of coincidence therewith, whereby said vibratory bed-die is left stationary and free for a time sufficient to permit the convenient and accurate adjustment thereupon of a blank or other metal to be subjected to the action of the dies, as hereinafter fully described.
In the accompanying drawings, Figure 1 is a front elevation of my improved machine. Fig. 2 is a vertical section through line so a: of Fig. 1, showing the vibratory bed-die in position to receive the metal. Fig. 3 is a similar view, showing the revolving die and vibratory die about to engage and move together to act upon the metal placed between them upon the bed-die. Fig. 4 is a detached and enlarged perspective view of the roller and revolving die. Fig. 5 is a similar view of the bed-die and its vibratory carrier. Figs. 6 and 7 illustrate the manipulation of the metal in forming a taper-legged staple, and Fig. 8 shows a staple as it appears after the first action of the dies.
The letter A designates a roller provided with a seat for a removable die, B, which is (ModeL) arranged between two projections, G, at opposite ends of the roller, the edges of the dieblock being preferably beveled to take under the undercut inner edges of these projections. A suitable Wedge driven between the die-block and one of the projections serves to hold the former against lateral displacement. The roller is provided with suitable journals mountedin fixed bearings in the standards E.
The letter F indicates a vibratory arm, the lower end of which is pivoted in a vertically-adjustable block, G, seated upon a wedge-shaped plate, H, arranged to slide upon the base 1. Screws 70 working through correspondinglythereaded bearings on the base, serve to force the wedge-shaped plate transversely under fthe block G to raise it, and a screw, it, holds the said block in place against the standards.
The upper end of the arm F is provided with seat for a bed-die, L, seated and wedged be- ;tween two flanges orjaws,ff. From the front portions of the flanges f f project lugs f f, which temporarily en gagewith the projections O O of the roller, as, will presently be 6X1 plained. The arm F is drawn rearward, or to ward the standards, by a spring, Ml, and a stop, m, fixed to one of the standards limits the rearward movementot the arm. The normal position of the arm F against the stop m is such that when, by the revolving motion of the roller, the projections G of said roller strike the lugs ff the front edgesof theupperorrevolving (lie, B, and the bed or vibratory die L will be in the proper relative position to act upon a blank or piece of metal placed between them and supported by the bed-die. This position of the parts is illustrated in Fig. 3. The projections 0 cause the arm F to move outward as the dies take hold of the metal, thus insuring a properly coincident initial action. The dies move together as long as the metal is held between them but as soon as they reach the positions shown in dotted lines, Fig. 3, the revolving die leaves the metal, which is held by the tongs of the operatorin front, and there being no further pressure upon the bed die, the spring M immediately retracts the arm F to its stop m, bringing the bed-die to its normal position, ready to receive the metal for another operation. The revolvingdie, continuing its movement, is carried out of the operated upon separately, ,suchas staples, and

upon the die.
The manner of manipulating a staple while being acted upon by 1n y machine is illustrated in Figs. 6 and 7.
In Fig. 6, 0 indicates the staple-blank laid upon the bed-die to receive the first action, and Fig. 8 shows the'form of the legs of the staple after the first action. It will be seen that these legs are reduced to an oval shape, which it is necessary to upset or condense into a round and somewhat tapering form. In order to accomplish this it is evident that the dies must operate upon the legs separately. One of the legs is therefore inserted in the chamber N in the bed-die block, while the other lies upon the surface of the die, ready to be acted upon for the upsetting of the oval into a roundform.
The dies are provided with grooves q q q, those q q operating to form the two legs into the oval shape at one pass, and the central groove, q, operating upon the legs separately to upset and finish each leg into round and somewhat tapering shape.
' The apparatus may, of course, be provided with various kinds of dies, according to the article to be produced, and is especially applicable to small articles of irregular shape, such as gun-cocks, pitchforks, and tools of various kinds.
What I claim is 1.' In a metal-forgin g machine, the combination, with a continuously-revolving die, of a vibratory bed-die arranged to co-operate therewith in producing a rolling or drawing action upon metal, and means for automatically returning the vibratory die, after the completion of a pass, to its normal position independently of the movement of the rotary die, and holding itthere for an interval of time before the revolving die again reaches a position of coincidence therewith, substantially as described, whereby the said vibratory die is left stationary and freely accessible for a sufficient time to permit the convenient and accurate adjustment thereupon of a blank or other metal to be subjected to the action of the dies.
2. In a machine for forging metal into irregular forms, the combination, with a revolving die, of a vibratory die-block having an open chamber formed under its die-surface to receive a limb or member of an article, which is then unacted upon while another part is acted upon by the dies.
3. The combination,with the revolving roller provided with the die-seat and projections O, of the vibratory arm F, provided with the dieseat and lugs-ff, a spring for retracting the said arm, and a stop for limiting the return movement of the same, substantially as described.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnessesr WILLIAM B. HAYDEN. Witnesses:
