SPECIFICATION forming part 0f Letters Patent No 668,656, dated February 26, 1901.

Application filed February 24, 1900. Serial No. 8,359. (No model.)

To all whom it may concern.'

Be it known that I, WILLIAM H. MINER, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois,haveinvented a new and useful Improvement in Tandem-Spring Draft-Rigging for Locomotive-Tenders, of which the following is a specication.

My invention relates to improvements in tandem-sprin g draft-rigging for railway-cars.

My invention is an improved tandem-spring draft-riggingspecially designed for use upon locomotive-tenders'.

My invention consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown and described, and specified in the claims.

In the accompanying drawings, forming a part of this specification, Figure'l is a plan view of a tandem-spring draft-rigging embodying my invention. Fig. 2 is a side elevation, partly in longitudinal section, showing the draw-bar, springs, and followers, and one of the stop castings or casings. Fig. 3 is a vertical cross-section on the line @c a, of Fig. 2. Fig. I is a vertical cross-section on the line yy of Fig. 2, and Figs. 5 and `6 are perspective views of one the stop castings or casings, showing the opposite faces thereof.

In the drawings similarlett-ers of reference indicate like parts throughout all the figures.

In said drawings, A A are draft-timbers or center sills, between and below which the draft-rigging is arranged, and A the central longitudinal beam or sill, below which the draft-rigging is arranged. A2 is the cross or end sill of the tender. A3 is the buffer-plate or face-plate of the end sill,A4 the front carryiron, A5 the body-bolster, and A6 the center plate on the bolster, A7 the coupler, and A3 the draw-bar. All these parts are or may be of the usual or customary construction.

B is the pocket-strap of the draft-rigging, the same having bent ends or shoulders b b engaging the shoulders a a at the rear end of the draw-bar and which is secured rigidly to the draw-bar by the rivets b'.

C is the abutment-block, secured between the upper and lower members of the pocketstrap by the rivets c.

D d D d' are the tandem-arranged springs between the followers F F and F2 F3. The squared rear end a of the draw-bar abuts against the front follower F, the abutmentblock C abuts against the middle followers F' F2, and the transverse rear end b3 of the folded or bent pocket-strap ab uts against the rear follower F3.

G G are the stop castings or casings. Each of these stop-castings is furnished with three stops g, g', and g3 for the ends of the four followers to abut against and also with a guide# flange g3, which tits above the followers and serves as the upper guide therefor, and with longitudinal strengthening-ribs g4 g5, the inner edges of which bear against the ends of the followers and serve as end guides therefor, as well as to strengthen the stops g g g2 and the stop-casting as a whole.` The lower guide for the followers G is made in a separate piece from the stop-casting and is removably secured thereto by bolts. Each of the stop-castings is also furnished with an integral top plate G2 and integral end plates G3 G4, the former abutting against the bodybolster A5 and the latter against the end crosssill A3. The rear edge of the stop-casting G is furnished with an offset G5 to receive the flange of the center plate A6, and the front end thereof is provided with an integral projection G3, fitting under the end sill A2 and receiving the front carry-iron A4. outer or opposite faces each of the stop-castings G is provided with box-shaped lateral projections or extensions g3 97 g3 to iit or abut against the vertical face of the draft-timbers A A, and thus bring the two stop-castings near together, so that short or ordinary length followers may be used notwithstanding the wide distance apart at which the draft-timbers A A are necessarily placed in tenders, while at the same timethe portion of my new and improved stop-casting which extends above the upper guide-flange g3 serves to bring the recesses or channels for the followers to reciprocate in to the required level for the draw-bar and draft-rigging and also at the same time enables the upper face-plate G2 of the stop-casting to abut directly against the lower face of the central sill A', so that it can be rigidly and firmly secured thereto by bolts H, which pass through said sill A', the stopcastings, the lower guides G', and the cross- On their IOO bars K. The top or upper face-plates G2 of the stop-castings abut directly7 together at their inner or meeting edges and are also provided with cross-ribs g, which are let into grooves cut in the central sill A, and thus more securely anchor the stop-castings in place against the great pulling and buffing strains which are transmitted. through the draw bar, springs, and followers. As the two stop-castings G G abut directly together at their upper face-plates G2 G2 the bolts M, which secure them to the side sills A A, serve to rigidly and firmly anchor the stop-castings to the side sills notwithstanding the fact that the side sills are wide apart and the fact that the main body of' each stop-casting is located some distance from each side sill by reason of the lateral projections or extensions gG g7 g8, and as my stop-castings are not only thus firmly bolted to the side sills A A and central longitudinal sill A', but also abut directly at their ends against the end sill A2 and the body-bolster A5, it will be readily understood by those skilled in the art that my stop-castings are united to the frame of the car or tender with very great strength and lirmness, and also owing to my new and peculiar construction my stop-castings themselves each possess very great strength and rigidity, as the top or upper integral plate, in connection with the upper integral guide-ange g3 for the followers and the longitudinal ribs g4 g5, not only gives great strength to the stopcasting as a whole, but directly braces and strengthens each of the stops g g g2.

N N are the tie-rods, which extend through the tender or car from end sill to end sill. The lateral projection or extension g6 at the end of the stop-castings are furnished with holes or openings for these tie-rods to pass through.

The middle stop g of each stop-casting is made a little deeper or to project out laterally a little farther than the end stops g g2 at the portions g10 g10 thereof, just above and just below the followers, which portions are engaged by the side edges of the draw-bar extension or pocket-strap B, so that the drawbar and the pocket-strap may turn orswing laterally on the projections of these middle stops as a pivot as required when the train is passing around curves. The end stops g g limit the extent of this laterally swinging or turning movement of the draw-bar and pocketstrap.

I claiml. In a tandem-spring draft-rigging for locomotive-tenders, the combination with the draft-timbers and a central longitudinal sill between the draft-timbers, the end sill and body-bolster, of a pair of stop-castings abutting at one end against the end sill and at the other against the body-bolster and provided with three stops and upper and lower guides for the followers, and an integral top plate above the upper guide fitting against the central longitudinal sill, the top plates 0f said stop-castings abutting directly together at their meeting edges, and each of said stopcastings being furnished with lateral projections or extensions fitting against the drafttimbers, a draw-bar, a pocket-strap, two tandem-arranged springs, and followers at both ends of both springs, substantially specified.
