T0 (r/ZZ whom it may concern:

Be it known that we, ARTHUR L. TURNIP- snnn and SIDNEY THOMAS WILLIAMS, citizens of the United States,'residing at Memphis, Shelby county, State of Tennessee, l1avein vented certain new and useful Improvements in Means of Attaching Draft -Timbers, of which the following is a specification.

Our invention relates to certain new and useful improvements in means of attaching draft-timbers to the draft-sills of freight-cars.

It has for its object to provide means of attaching draft-timbers, whereby same may be attached or removed without the necessity of removing any bolts or of entering the car, especially where the car is loaded, since such entrance would then necessitate transferring; or shifting the load. We accomplish this object in the manner more fully hereinafter set forth in the drawings, specification, and claims.

In the drawings, Figure 1 is a sectional side elevation of one end of a freight-car, showing the relation of the draft-sills and draft-timbers, said section being taken on the line 1 l of Fig. 2 looking in the direction of the arrow. Fig. 2 is a bottom plan of the end of a car looking up from beneath, showing an ar rangement of car and draft-sills with drafttimbers attached. Fig. 3 is a view on a larger scale, being approximately one-half full size, of the key and fastening piece which constitutes our invention.

Referring now to the drawings, in which like parts are indicated by like letters of ref erence in all the views, A A are the car draftsills, to which the draft-timbers B are to be fastened.

O C are the key and fastening pieces,which are recessed into the draft-sills and the drafttimbers B and are bolted to the draft-sills A by bolts D passing through the holes (Z in said pieces, the heads of the said bolts being preferably countersunk in the under side of the piece 0 and the edge a of same being brought flush with the lower edge of the draftsills A, The draft-timbers B are recessed, as before stated, to fit the projecting lower halves of the key-pieces C, and bolts E are passed through the said timbers and into holes Gr, Fig. 3, cored into the center of the said key-pieces, which holes fit the head of the bolt E and have a centrally-located bolt-hole 9 leading from them through the bottom of the piece. A slot F is cut outward on one side from this cored hole G and the bolt-hole g, which slot permits the insertion of the bolt from the side. The hole G for the bolt-head is deeper than the bolt-head, and the slot F into it from the side does not come flush with the bottom of it, so that cars or lugs f are left at the entrance, which lugs form a pocket into which the head of the bolt drops, which pocket serves to keep the head of the bolt from working out sidewise. The mouth of the slot F is slightly rounded to guide the bolts E to place.

To attach the draft-timber B, the recesses are cut to fit the lower half of the key-pieces G, and bolts E are inserted through the timbers in the center of these recesses, the heads of said bolts being left projecting above the top of the timber. The timber is then brought parallel to the draft-sill A, the bolt-heads coining opposite the slots F, through which they are slipped into the cored holes or pockets G. The nuts of the bolts E on the under side of the draft-timber B are then screwed up, the bolts being thereby drawn down into the pockets G and the timber drawn to place. Bolts H may be next inserted through the outer end of the drafttimber B and the dead-wood I, thus completing the attachment of same. When thus bolted up, the pieces 0 serve as keys to take up the draft pull, and the bolts E hold the timbers B to place. Should a draft-timber be broken or injured in any way, it may be replaced by simply loosening the bolts E and tapping them on their lower ends to disengage their heads from the pockets Gr, and when the bolts are so loosened slipping the timber out sidewise. Since the upper part of the key is stronger and is held by two bolts and the draft-sill is comparatively protected, no damage ordinarily will result which will make necessary the removal of the said key-piece from the draft-sill. The advantages to be derived from this construction of course become especially noticeable when a loaded car has to be repaired, since the load will not have to be transferred or unloaded to remove bolts.

It has been customary to insert a bolt through both the draft-sill and draft-timber, the bolt-head being inside the car. When, therefore, it became necessary to remove a bolt for any reason, access was necessary to the head of same in the car, and this often necessitated shifting or transferring the load.

While we have shown and described our invention with especial reference to railroad freight-cars, it is of course evident that same may be used in any analogous position to hold two timbers together.

Having now fully described our invention, what we claim, and desire to secure by Letters Patent of the United States, is-

1. The combination with the draft-sill, and draft-timber to be fastened together, of a key connecting-piece,bolts through said key-piece and draft-sill to attach said key-piece to said sill, a depressed pocket in said key-piece, a slot leading from one side of said Key-piece to said pocket and a bolt inserted through said draft-timber and into said pocket, substantially as and for the purposes set forth.

2. The combination with the draft-sill and draft-timber to be fastened together and mortises in each of said timbers, of key connecting-pieces, fitting said mortises, bolts passing through said key-pieces and draft-sill to attach said pieces to said sill, a depressed pocket in the center of each key-piece, a slot in each leading from the side to said pocket and a bolt in each of said pockets extending through said draft-timber, substantially as shown and described.

3. The combination with two timbers to be fastened together of a key connecting-piece, bolts through said key-piece and oneof said timbers to attach said key-piece to said timher, a depressed pocket in said key-piece, a slot leading from one side of said key-piece to said pocket and a bolt inserted in said pocket and extending through the other of said timbers, substantially as and for the purposes set forth.
