SPECIFICATION forming part of Letters Patent No. 421,142, dated February 11, 1890. I

Application filed July 31, 1889- Serial No. 319,822. (No model.)

To all whom it may concern.-

Be it known that 1, JAMES REILLEY, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Dies for Forging Car Couplers, of which the following is a specification.

This invention relates to dies for forging that class of car-couplers which are commonly known as the Miller coupler.

The object of my invention is to construct a pair of dies whereby couplers of this class can be produced more expeditiously than heretofore, and at the same time be finished in a superior and more uniform manner.

The invention consists of the improvements which will be hereinafter fully described, and pointed out in the claims.

In the accompanying drawings, Figure lis a front elevation of my improved dies. Figs. 2 and 3 are elevations showing: opposite sides of the dies. Fig. l is a top plan view of the lower die. Fig. 5 is a bottom plan View of the punch or upper die. Fig. 6 is a vertical section of the dies in line mac, Fig 1, looking in. the direction of the arrow. Fig. 7 is a plan view of one of the cheek-pieces of the coupler, showing the form thereof previous to being operated upon by the dies. Fig. 8 is a similar view of a finished cheek -piece. Fig. 9 is a plan View of the filling-piece of the coupler, showing the form of the same before being operated upon by the dies. Fig. 10 is a similar View of afinished filling-piece. Fig. 11 is a side elevation of a finished carcoupler.

Like letters of reference refer to like parts in the several figures.

A represents the shank or body, and B the head or hook of the coupler. composed of two cheek-pieces O and an 1ntermediate or filling piece D. The two cheekpieces are of the same outline, and are socured to opposite sides of the fillingpiece D by welding, riveting, or otherwise, as represented in Fig. 11.

The head 13 is provided with a lateral extension or offset 1), forming the hook, having a curved face 0 and a curved back 0, so as to form a V or arrow shaped head. The front is formed.

The latter is ends or head port-ions of the cheek-pieces O project beyond the filling-piece D, so as to form a cavity or recess (1 for the reception of an ordinary coupling-link. This filling-piece is concaved at cl, as shown in Fig. 10, to form a seat for the end of the link.

E represents the lower stationary die, which is secured to the anvil-block of a steam or power hammer.

F represents the punch or upper movable die which is secured to the head of the powerhammer.

The die E is provided on its upper side, near one of its lateral edges, with an upwardly inclined face e for forming one edge of the shank portion A of the coupler, a downwardly and forwardly inclined face or shoulder e, and an upwardly and forwardly curved or concave face a, which latter, together with the inclined face 6, form the hook or project ing portion 7) and the curved face a of the coupler.

f represents an upwardly inclined face formed on the lower side of the upper die or punch F. The face f is arranged immediately above and parallel with the face 6 of the lower die E, and between these faces the shank A The face f terminates at its front upper portion with a concave face f for form ing the retreating back 0 of the coupler.

g is a passage or guide-space formed at the adjacent front faces of the dies E and F, in

rear of the faces f 6 respectively, for the ad mission of a staff or bar g, which latter is welded to the front or head portion of each cheek-blank, as shown in Fig. 7, whereby the blanks are manipulated by the operator during the operation of heating and forging the same. This staff is cut off from the head B when the cheek-piece is finished, as shown in Fig. 8.

h represents a downwardlydnclined face formed on the opposite upper side of the lower die E, near the lateral edge thereof, for forming one side of the shank portion A of the filling-piece D.

h represents a convex face formed above the lower inner portion of the face it and facing the latter, whereby the concave or link seat (Y of the fillingpiece D is formed.

partly across the die.

cheekepieces and filling-pieces are forged bet' represents a downwardly-inclined face formed on the upper dieF above the inclined face it and arranged parallel therewith, whereby the opposite edge of the shank portion A of the filling-piece-D is formed.

1 represents an upwardly-inclined face or shoulder, and 2' a downwardly-curved or concave face,which latter, together with the shoulder 1', form the hook or projecting portion 5 of the filling-piece D.

The lower die E is provided on its upper side with a fiat working-face or anvil J, which extends across the die from the faces 6 e 6 whereby the cheek-piece is formed, to the faces h h, in which the filling-piece is formed. The upper movable die or punch F is provided above the face J, and adjacent to the faces f f, with a similar flat face J, which extends The blanks for .the

' tween these fiat faces preparatory to placing inclined faces 6 6' e the blanks between the shaping faces or dies.

The cheek-pieces are forged between the fiat faces J J to the form shown in Fig. 7 before being placed in the s'liapingdies, and the filling-pieces are forged in a similar manner to the form representedin Fig. 9. Each cheek-piece blank consists of a flat plate K, having at its end the above-described staff or bar g. The filling-piece blank consists of a..narrow shank portion 1 and an enlarged or laterally-projectingportion Z. WVhen the cheek piece blank has been forged to the form shown in Fig. 7, it is heated and then placed with its lower end upon the It is then shaped by bringing the faces f f of the upper die down upon the blank. The shank is forged and drawn out to the proper length by alternately placin git between the flat anvil-faces J J and the die-faces f c.

When the fillingpiece blank has been forged to the form shown in Fig. 9, it is heated and placed with its long fiat edge upon the inclined face h, and with its lower end resting against the front side of the convex face h It is then shaped by bringing the upper shaping-faces q; 2" 4?. down upon the blank. The shank of this piece is formed to the proper width between the shaping-faces i and h, and is drawn out to the proper length between the flat faces J J.

The heads B of the cheek pieces O are forged somewhat thicker than the shanks A. The metal gradually tapers from the head toward the shank, so as to form a wide coupling-face and a comparatively narrow shank. The cheek-piece is preferably forged to one thickness over its entire length. This construction forms an offset G when the parts are welded together. This offset or curved connecting portion is formed by assembling the three parts and placing the same upon the flat anvil-face J of the lower die, below a recessed face M formed on the lower side of the upper die or punch F on one side or adjacent to the face J. The face M is curved at m to conform to the offset on the lower side of the coupler.

With my improved dies car-couplers can be produced in much less time than heretofore, and by a single heating, and in a more uniform and highly-finished manner, than by hand-work, whereby a great saving of time and labor is effected and the cost of produc- .tion greatly reduced. I
