NlACHlNE FOR ROLLING COUPLlNG-PINS.

SPEGIF'ICATEGN forming part of Letters Patent No. 286,324, dated October 9, 1883.

Application filed May 24, 1883. (Xo model.) I

` T all whom it Hwy concern:

Beitknown that I, JosnPn Masern, of Detroit, in the county of Wayne and State of Michigan, have invented new and useful Improve-ments in Machines for Rolling Coupling- Pis; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which 'form a part of this specificaxo tion.

p This invention relates to certain new and useful improvements in the construction of that class of machines especially designed for rolling or forming draw-pins for car-couplings, such pins being formed from a suitable blank,

which is heated and' dropped into the machine, from which it emerges formed into the desired shape.

The invention consists in the peculiar construct-ion, arrangement, and various combinations of the parts, all as more fully hereinafter set fort-h.

Figure 1 is a side elevation of myimproved device. Fig. 2 is a w-'ertieal central section. 2 5 Fig. 3 is a cross-section on the line X X in Fig. 2. Fig. is a cross-section showing the dieroll in its position near the finish of the rolling. A In the accompanying drawings, which form 3o a part of this speciicationfA represents a suitable frame, in which is properly journaled the transverse shaft B which is provided between its bearings with the spider arms C, `upon which the die-roll D is concentric-ally secured. 3 5 E is a stationary die roll or bed, placed concentricallyto the revolving die-roll D, and

held in position by the transverse keys a a. c a',

three of which bear against the outside oi' said bed, and all pass through suitable slots in the 4o frame A. The outer die roll or bed, E, is in the form of a hollow cylinder, with a portion of its' body between c and dent away, so as to y expose the face of the die-roll D. The inner face of the die roll or bed E is grooved from ,4,5 c to d, and the inner die roll, D, is grooved around its entire face, said grooves being intended to roll a blank inserted between them gradually into the desired form. lThe sizeof the rolls D and E is so calculated that if a 5o blank to produce an ordinary coupling-pin is introduced at c, one revolution (or nearly one) will roll.V the blank from the point of introduction at c in the direction of the arrow marked ,on Fig. 2 to the point d, where, owing` to the cutting away of the die-roll E, the pin will roll out. As the blank can only be gradually welded into the desired shape, the groove on the inner face of the roll E and the one on the outer face ofthe roll D are at their startingpoints-which are at c and e, respectivelyof 6o the shape shown at Fig. 3 on top. From thence they have a slight draft in opposite directions toward their terminal points, at which they are of the exact cross-section desired for the coupling-pin. The grooves f and g, also of unequal length, must bring, during their coaction upon the blank, corresponding crosssections to bear again st the same, and therefore the blank can only be introduced when those cross sections register. Vith the machine 7o shown in the drawings, the right moment to introduce or feed the blank is when the point-s c and e register, and to perform this automatically a latch, F, is arranged, upon which the blank is deposited. This latch has a foot, 71,-, which bears against the face of the roll D, and supports the latch and blank in the position shown in Fig. 2 until said foot It drops into a notch, i, on the face of the roll D, and lets the blank fall upon the face of the-roll D, which 8o quickly draws it between the two rolls. To feed the blank in proper position, adjustable check-pieces k and Z are attached to the inletopening, as shown in Fig. 3. The two rolls D and E must also have a certain clearance between them, so as to allow any superfluous meta-l from the blank to escape, and also to admit of a limited adjustment ofthe r'ollE by means of the set-screwsm m. This adjustment is effected as follows: By turning in the set- 9o screw m, the grooved bed E, being connected to the crossbar E', through which said screws pass, can be raised to a limited degree, By turning in the screw mf, the bed can beadj usted forward. The serewm bears againstthe trans- 9 5 verse key c', and thus allows of adjustment in another direction. By varying the amount of travel of these screws, the space between the roll D and bed E can be .varied to a limited extent, but suiiieiently to change the size ofthe roo pins or to compensate for the Wear of the parts.

To communicate motion to the roll D, a gear- Wheel, H, is keyed upon one end of the shaft B, and another gear-Wheel, I, upon a countershaft, K, meshes with it and communicates motion from the driver L upon the. opposite end of the counter-shaft.

In the drawings I have shown a device for flattening the pins when required, but make no claim to it in this application, as it may form the subject-matter of a separate application.

Vhat I claim as my invention is- 1. The combination, With a frame, A, a grooved bed, and a grooved roll provided with a notch, i, of,ra latch,' F, constructed and arranged to be automatically dropped by the ro- 2o tation of said roll, substantially as described.

2. The combination, with the frame A, the grooved bed E, and the roll D, having notch i, of the latch F, provided with the foot h, adapted to reston the roll and drop the blank When 25 the step e approaches the beginning` of the bed, all constructed and arranged substantially as shown and described.

3. The combination of the frame A, the roll D, supported therein, and the bed E, 'with the 3o set-screws m, for adjusting the bed to the roller, substantially as described.
