BENJAMIN F. PEACOOK, OF ANNISTON, ALABAMA, AND FRANCIS TOY PEACOOK, OF SPARROWS POINT, MARYLAND.

METAL FORGI NG AND SHAPING PRESS.

SPECIFICATION forming part of Letters Patent NO. 505,955, dated October 3, 1893.

Application filed June 27. 1892. Serial No. 488.166. (No model.)

To all whom it may concern:

Be it known that we, BENJAMIN F. PE

COOK, residing at Anniston, in the county of Calhoun and State of Alabama, and FRANCIS TOY PEACOOK, residing at Sparrows Point, in the county of Baltimore and State of Maryland, citizens of the United States, have invented certain new and useful Improvements in Metal Forging and Shaping Presses; and

' we do declare the following to be a full, clear,

and exact description of the invention, 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, and to the letters of reference marked thereon, which form a part of this specification.

Our invention relates to metal forging and shaping presses.

The object of our invention is to forge axles,

rods, shafts and the like, by means of a fluidpressure press of novel construction, whereby the output of the machine is accomplished in a simple, efficient, and economical method.

Figure 1 is a horizontal sectional view and partial plan of a machine embodyingour invention. Fig. 2 is a side elevation of the same, partially in vertical section. Fig. 3 represents an end elevationof the machine. Fig. 4: represents a side elevation of a modified form of a machine, to which we have also applied our improvements.

I Our invention consists in the following construction and combination of the opera tive parts, which will first be fully described and set forth in the specification, and the features of novelty therein then pointed out and claimed.

In' the drawings -A represents the foundation bed upon which our machine is mounted.

. and the standards themselves are mutually braced against outwardly thrust strains or blows, tending-to-force the standards farther apart,'by the'combined brace and guide rods Io. The'standa'rd's'B carry the die-holders D "Inthe duplex machine two cross-heads F v are employed which reciprocate-back and forth upon the stay and guide rods 0. These cross-heads carry the movable die-holders G and the movable dies H, the latter being arranged to reciprocate adjacent to and in line with the stationary dies E.

For the purpose of reciprocating the movable dies H simultaneously the following mechanism is preferably employed: I is a fluid-pressure cylinder disposed below the machine and interm'ediately of the standards B. J is the cylinder-piston having a vertical movement therein which is adapted to operate a toggle device K, for the purpose of operating the movable dies. This toggle K consists of a vertically moving piece L having suitable connection with the piston J. To this piece are pivotally connected four levertoggle arms M, which in turn are pivotally connected, respectively, to the oppositely arranged cross-heads F.

In making connection between the crossheads F and the toggle-armsM, so as to secure a jointed pivotal action we preferably project into correspondingbearings on' the inner sides of the toggle-arms M, and hold the latter in position. These pieces N we pro,- (gfer to bolt to the cross-heads F in any suitable manner. The outer ends of the togglearms M are rounded, being received into corresponding depressions or bearings in the opposite faces of the cross heads F, and abutments-P are formed at the outer ends of these bearings in the cross-heads which serve to hold the toggle-arms M in position and upon the pintles 0. An upward movement of the piston J operates upon the toggle de-i vice K to move the dies H toward the dies E.

For the purpose of returning the piston J, or in other words moving the dies H away from the dies E, we provide a second fluidpressure cylinder Q, having a piston R which rests upon the top of the vertical piece L of the toggle K. This piston or ram R will, when pressure is introduced into the cylinder Q, force the toggle down and the dies-apart.

We prefer to provide the cylinder Q with oppositely extending arms S which terminate in bearings T secured to and carried 'by the upper stay and guide rods 0, the fluid pasth-rough theconnecting bolts V.

sages to the cylinder .Q being through-.the bearings Tand the arms S. "The'onter ends of the arms S are journaled in the bearings T so as to oscillate therein, thereby permit- 5 ting a limited rocking movement to the cylinder Q to compensate for any lateral movement of the verticirllymeiring piece Ifiof the toggle K. In like manner the bearings 'flof the cylinder Q may be moved bodily along the rods 0 to provide for any-undue endwise movement of the toggle.

It will be understood by the term fluidpressure cylinders. that anymlrnownnfluid or, gaseous agent may be employeds'ubh as waz 5 ter, oil, steam, air, gas,-'caloric *o1 theflike.

In like manner we may vary the form of our togglegear and of the fluid-pressure cylinders. All these changes and modifications we can make and still comewithin the scope'of our invention.

We prefer to leave the opposite ends of the diesE H open sothat-a portion of the forgings therein may project axially at the opposite ends, whereby the operator may secure said-ends in slingswor tongs from a movable crane, and thereby secure perfect control in I" man ipulatingthe forging in the various blows -or strains to which he may subject it. .We cla im--- I 1.4 Ima forgiirg machine empress; the combinationuofwdie holding istandards; stayr'and guide rods connect-i ngt thetsame a cross-head V carry-i ngra idieanovin g onmsaidr rodst-ai toggle- Hdeviceaanranged between their cross-head and I thestandards fomactuatingisaid reross head,
