COMBINEDFR!CTION AND DIRECT-ACTING DRAFT-RIGGING.

SPECIFICATION forming part of Letters Patent No. 717,678, dated. January 6, 1903. Application filed November 15, 1992. erial No. 131,459. (No model.)

My invention relates to friction spring draftrigging.

The object of my invention is to provide'a combined friction and direct-acting spring draft-rigging of a simple, compact, strong, efficient, and durable construction which may be cheaply manufactured and readily and conveniently applied to the car.

My invention consists in the means I employ to accomplish this result-that is to say, it consists, in connection with a draw-bar and draft-iron in line therewith having a straight friction-face-on one side and double-incline friction-faces on its opposite side, a transversely-movable friction block having donble-incline friction-faces en gaging the doubleincline friction-faces on the draft-iron, and a transversely-arranged spring acting against said friction-block, of a longitudinally-arranged or direct-acting spring and followers therefor on the opposite side of the draft-iron from said transversely movable frictionblock, so that the draft-iron is located centrally and directly between the direct-acting spring and the transversely-acting spring and its friction-block, the draft-iron having wings for operating the followers of the direct-acting spring.

It also consists, in connection with these parts, of a pair of side plates or stop-castings secured to andbetween the draft-timbers or center sills of the car and provided with suitable transverse guides for the transverselymovable friction block and a longitudinal case or guide for the followers of the longitudinal or direct-acting spring.

It also consists in providing said side plates or stop castings with laterallyremovable transverse bolts for securing the same together and which also serve as removable stops for the followers of the longitudinallyacting spring, so that said spring and thefollowers therefor may be inserted and removed through the open end of the guide when such removable stop-bolts are taken out and so that the draft-timbers or center sills will not interfere with the removal of said bolts.

It also consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown or described.

In the accompanying drawings, forming a part of this specification, Figure 1 is a vertical longitudinal section of a combined friction and direct-acting spring draft-rigging embodying my invention, the section-line being indicated by the line 1 1 on Fig. 2. Fig. 2 is a plan view showing some of the parts partly broken away and others in horizontal section. Fig. 3 is a cross-section on line 3 3 of Fig. 1. Fig. 4 is a detail sectional view showing the followers and thimbles for the direct-actingspring. Fig. 5 is, a detail view of one of the thimbles. Fig. 6 is a detail perspective view of the draft-iron. Fig. 7 is a detail perspective view of the side plates or stop-castings.

In said drawings, A represents the drafttimbers; A, the center sills; A the crosssills; A the buffer-block, and A the carryiron.

B is the draw-bar of the coupler B.

D is the sliding friction-draw-bar extension or draft-iron, the same being directly in line with the draw-bar and connected theretoby a clip or yoke 12, passing through an eye at in the draw-bar extension or draft-iron,the crosspivot d of which eye is slightly rounded or beveled, so that the draw-bar and coupler may have the necessary slight lateral vibratory movement as well as a vibratory movement up and down.

F F are the side plates or stop-castings, fitting being the draft-timbers and securely attached thereto by bolts f.

The draft-iron D has a straight friction-face d on one side, preferably its upper side, which is in sliding frictional engagement with the stationary friction plate or face G, said plate or face G being securely fixed or anchored on the side plates or stop-castings F F, but preferably made in a separate piece therefrom or not integral therewith. The draft-iron D has on its opposite side from the straight friction-face d and preferably on its lower side double-inclined friction-faces d d, which cooperate with the double-incline frictionfaces h h of the transversely-movable friction-block H, which is acted upon by the transversely-arranged spring K. The transversely-movable friction-block H has a barrel or flange h to receive the spring K, and the spring K is supported at its lower end by a removable spring seat or cup K, which is removably secured to the side plates or stopcastings F by cotter bolts or pins K having keys K the pins or bolts K extending through suitable lugs f on the side plates or stop-castings. The side plates or stop-casting have transversely-extending guides f for the friction-block H to reciprocate in or on transversely while holding the same in position longitudinally in respect to the drawbarordraft-iron. Thesideplatesorstop-castings are provided directly opposite or above the friction-block and its transverse guides f with alongitudinal guide f to receive the longitudinally-arranged direct-acting spring N and its followers P P, the followers P P being preferably circular and the longitudinal guide f therefor preferably cylindrical in form. The guide f is preferably formed one-half upon each of the side plates or stopcastings F and has open ends to facilitate the insertion and removal of the spring N and followers P. The stops ]"f for the followers P Pto abut against are preferably made in separate pieces and removable from the guide f and the side plates or stop-castings upon which said guide is formed. These removable stops f f may preferably also serve as bolts for bolting or securing together the two side plates or stop-castings F F. These bolts are preferably laterally removable from the guides f of the side plates or stop-castings, this being conveniently effected by providing the holes f through which the bolts extend, with lateralopeningsf through which the bolts may be removed laterally when their nuts are loosened. This prevents the draft-timbers or center sills from interfering with the removal of the bolts, as they would do if the bolts had to be withdrawn lengthwise instead of removed laterally.

The draft-iron D is provided with central upright wings d d for operating the followers of the longitudinal or direct-acting spring. Thimbles P, having sockets p to receive the ends of the rod or stem 19', which extends through the spring N, are preferably inserted between the wings d and the followers P. A small spring N may, if desired, be inclosed within the main spring N. To cause the direct-acting spring N to come first into action under either pulling or buffing strains and the transversely-acting spring and frictionblock to come subsequently into action, the incline friction-faces (1 cl on the draft-iron are more widely separated than the cooperating friction-faces h h on the friction-block, thus leaving some play for partial compresslon ofthelongitudinal or direct-acting spring before the friction-block begins to compress the transverse spring K, and as the downward or transverse movement of the friction-block H is somewhat less than that of the followers P, I prefer to so arrange the parts that the direct-acting spring N is slightly or partially compressed when applied or assembled, as this enables me to use springs of the same size or length and still have both fully compressed by the full movement of the draftiron, and the strength of both is thus fully utilized.

' The draft-iron D is provided with the central web 01 bridging the incline friction-faces d d to strengthen the'draft-iron, and which Web fits in a corresponding slot formed in the friction-block H.
