DRAW-BAR EQUIPMENT.

Application filed August 13,1909.

Specification of Letters Patent.

Patent ed May 6, 1913.

Serial No. 512,634.

y, State of Ohio. have invented a certain new and useful Improvement in Draw-Bar Equipments, of which the following is a specification.

The object of this invention is to provide a an improved draw bar rigging or equipment in which the construction is simplified, cheapened and rendered more durable and in which the draw bar can be removed for repairs or replacement with great facility.

The invention is embodied in the details of construction hereinafter described and pointed out in the appended claims.

In the accompanying drawings forming a part of this disclosure, Figure 1 is a central vertical section taken longitudinally of the car but with the draw bar shown in full lines; Fig. 2 is chiefly a side elevation of one side of the equipment with the draw har removed; Fig. 3 is a cross section on the line www Fig. 1; Fig. 4 is a top plan view of the cheek plate removed from the sill; Figs. G and 7 are side, end and plan views, respectively, of the timber key. Fig. 8 is a side view of a fraction of the outer end of the reinforcing plate showing how it is notched to receive the timber key.

In the views 8, 8, designates the usual longitudinal sills which, as usual, extend the y entire length of the car at the under side if the fioor 9. The characters 10', 10, desig- .iate the draft timbers which are secured to the sills 8, 8. by means of bolts 11, but I firstsecure in the sills timber keys like that lshown in Figs. 5, 6 and 7. These keys are metallic devices of clip form comprising a central base or lug portion 1Q, with parallel cars 18 rising therefrom at each end. and a hollow dowel 14, with external ribs or feathers 14, rising from the middle of the lug portion 12. The sills are tirst bored with holes to receive the dowel body and to permit the passage of the bolts 11, and the key is driven into place in the sill, the feathers penetrating the wood of the sill and affording an extended surface for strains. After the keys are driven home they are further secured by horizontal bolts l5 passed through suitable holes in the ears 1S. 0n the inner side of the sills and between the sills and the ears are preferably secured metallic reinforcing plates 16 which are notched as at 16"l to receive the keys and are secured by the bolts 15. The outer ends of the plates 16 are secured by angle pieces 30 to the end sill 31.

The cheek plates, of which there are two and which are symmetrical duplicates of each other and secured to the draft timbers by bolts 17. These cheek plates each have thickened portions 18, 18, provided at their upper ends with notches 19, 19, to fit or engage on the lugs 1Q of the timber key. The cheek plate also has a central rib 20 which in conjunction with the portions 18, 18, forms cavities Q1, Q1, open at their lower ends. The lower ends of the thickened portions 18, 18, and the central rib 20 of each cheek plate, have recesses formed in them, all alining horizontally with each other, and through which a key 22 can be passed endwise and removably secured by means of a cotter pin 23 or other suitable device. The key 22 closes the lower ends of the recesses Q1 after the draw bar is put in place. designates the draw bar stem. This draw bar stem has secured upon it a yoke 25. and placed within the yoke are suitable springs 2G and followerl plates 27 of which there are four, one at each end of each spring as shown. The ends of the follower plates project beyond the opposite edges of the yoke Q5 and tit in the cavities 21, 21.

As before indicated the draw bar with its springs and follower plates are put into place by pushing it up into the equipment with the ends of the follower plates passed into the recesses Q1 after which the keys 22 are inserted and secured as described. The keys QQ thus subserve the function of securing the draw bar in place and the draw bar can be removed by removing t-he said keys. The strains on the draw bar stem are thus borne immediately by the cheek plates and draft timbers which in turn transmit them to the sills and the bolts connecting the draft timbers to the sills, and because these bolts press against the metallic portions of the timber keys a very rigid and secure connection of the draft timbers with the sills is obtained.

IVhat I claim is:

1. In a draw bar equipment, the combination with the longitudinal car sills and draft timbers, of a key between the timbers and sills consisting of a metallic member of clip form to straddle the sill and having its central portion provided with a hollow dowel to enter the sill and for the reception of a bolt.

2. In a draw bar equipment the combination with the longitudinal ear sills and draft timber, ot a key between the timber and the sills Consisting of a metallic member of clip form to straddle the sill and having its central portion provided with a hollow dou'el to enter thc sill and for the reception ot a bolt said dowel provided with external ribs or feathers.

S. ln a draw bar equipment, the Combie nation with the longitudinal car sills and draft timbers, a notched reinforcing plate on the sills, a cheek piece on the draft timbers and a timber key between the sills and draft timbers said timber key engaging the notched portion of the reinforcing plate and the cheek piece engaging the timber key.

4. In a draw bar equipment, the combination with the longitudinal car sills and draft timbers and a metallic cheek piece, of a key between the timbers and sills Consisting of a metallic member oi clip form including ears having bolt holes`r said metalliey mem her to stradille the sills and having its central portion provided with a hollow dowel to enter the sill and tor the reception of a bolt.
