To @ZZ whom it mctycorwerlc.- Y

Be it known that I, JAMES A. HINSON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and -useful Improvements in Draft-Sills for Railway- Cars; and I do declare the following to be a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to makeand use the same. Y

This invention relates generally to railwaycars, and particularly to a device for relieving the cars of the injurious effects of buffingblows; and it has for its object to provide a strong and durable sill for the cars, in combination with a coupler peculiarly adaptedV to coact with saidjsill; and it consists ofl the parts and combinations of parts hereinafter described and claimed.

In the accompanying drawings, forming a part of this specification, Figure l is a front elevation of my improved sill with couplerl removed; Fig. 2, a side elevation showing coupler in place; Fig. 3, aplan view, partly in-section; and Fig. 4, avertie-al section looking in the direction of the larrow on the line as Fig. 2.

Similar letters indicate similar parts in all the views. A

A represents a draw-head of the Janney type of car-coupler with the usual or any desired type of knuckle B, and C the draw-bar or stem. The stem C is secured to a strap or yoke D, through which the follower-plates E extend and have'their ends resting in recesses a, formed between stops l) in the draft-plates F, which are secured to the draft-timbers.

G is the main draft-spring for the coupler, arranged in the strap or yoke D and having its ends bearing against the follower-plates.

The parts described operate inthe usual manner to take up the bufng and pulling strains on the coupler when in use.

The draft-plates 'F according to my present invention are cast in one piece and form three sides of a rectangle, comprising the vertical wall c, the top wall d, and the bottom wall le, and in the space formed thereby the timbers 5o f may be secured by vertical or transverse bolts, as found necessary, to provide sufficient strength for the Work to which the plates are subjected. While the wood backing will orl dinarily give sufficient strength, still I do not desire to be limited thereto, as I may find it convenient to cast the plates in the form of hollow rectangles. At the forward or outer ends of the plates F a pocket I-I is formed to receive a bufflng-spring g, through which eX- tends the stem h of a buffing-head c, the rear end of the stem being reduced to pass through an opening in the rear wall of the pocket and enter a smaller pocket j, formed in the timberf, a slot 7c being formedn in the stem, through which a bolt Z is passed in order to secure the same in place and limit the longitudinal movement of the bufting-head. The spring d abuts at one end against the rear wall of the pocket and at the other end against the head z'.

A wooden or metal sill L is secured across the end of the car and is bolted to the draftplates by bolts m, passing through the perforated lugs 'n in said plates, and the said plates are further secured to said sill by the strapiron M, through which the bolts m also pass and which extends across the lower sides of the plates at the front and has its ends carried up to and boltedto the sill, as best shown in Fig. l. This strap or bar M also serves for a rest to support the coupler in its proper position. n v

The draw-head is castor otherwise provided with a laterally-extending flange N at each vside in position to engage the bufIing-headsc' when the coupler is'driven back in bufing and then only when the draft-spring has been vcompressed to a degree which is determined by the distance between the said flanges and the hunting-heads and which distance may be regulated when placingthe coupler in position between the draft-sills, so that the effect of IOO 1.
