DRAFT-BEAM FOR CARS.

SPECIFICATION forming part of Letters Patent N 0. 702,189, dated June 10, 190

Application filed July 25, 1901.

the provision of a metallic draftbeam which.

shall have a maximum strength and resisting power for withstanding the shocks and strains incident to-severe service; and for this pur pose the same consists of a draft-beam formed of integral parts, as hereinafter described.

It further consists of the combinations and arrangements of parts hereinafter described and claimed. I

In the accompanying drawings, which form a part of this specification, Figure 1 represents a vertical longitudinal section of a carfloor on the outer side of the sills or beams embodying my invention. Fig. 2 represents a view of one of the metallic draft-beams on a line through the longitudinal center of the car and in elevation. Fig. 3 represents a top plan view of the two draft-beams when united and bolted together.

Like letters indicate similar parts in the different figures.

Referring to the several views, the letter A designates one of the two central sills or stringers, and B an end sill, on which sills the fioorof the car is laid. F designates my improved draft-beams, preferably of malleable iron or steel,'each having a plain outer face and of substantially uniform height except at its front end, which is recessed for a purpose hereinafter set forth. The inner face of each of the beams F F has a horizontally-projecting upper or top wall or flange O and a horizontally-projectin g lower or bottom wall or flange P, with end connecting flanges. or walls. Intermediate of the said top and bottom walls are the horizon tally-extended ribs Q, which are united at their outer ends to the endflanges or walls of the beams and at theirinner ends to the vertical end walls or abutments M of the pockets L, which latter are adapted to receive the follower-plates which support the yoke of a draw-bar. (Not shown, as they are not a part Serial No. 69.694. (N0 model.)

of my invention.) Bosses R, connecting the top wall, ribs, and lower wall, are formed integral with the side plate or vertical wall of the beam, but projecting therefrom, so that the strength of said side wall is notimpaired bythe openings in said bosses through which 7 the bolts G and H are passed. Each of the The lugs of the two beams F F whenthe latter are in place abut against each other, as in Fig.6, and have coinciding horizontal openings, in which the securing-bolts K are inserted for binding said beams together. The

lugs S 8 also serve as a stop, limiting the rearward movement of the draw-bar.

The front ends of the draft-beams F F are rigidly secured in position by means of the sillB and the head-block C, the former by means of the bolts H, while the ends of the latter rest in recesses U on the upper faces of the 'saidbeams and are fastened thereto by means of the bolts 1, which pass vertically through said block and beams and also through the carry-iron; E, countersunk in a recess in the under face of each of the beams.

Abntting against the inner ends of the beams F F is the body-bolster D, which has itsupper edge inserted in recesses in'theunder faces of the sills A A. A strain-rod J is secured near its front and by a bolt to the outer face of each of the beams F F, the said end being bent and inserted in a recess Y in the beam, and the rod extending rearward through a horizontal openingin thebolster D is secured at its other and threaded end to a needle-beam. (Not shown). By fastening the front ends of the strain-rods JJ as described and passing them through the body bolster D a rigid front connection of said rods is effected, whereby a greater resistance to lateral as well as to longitudinal strains is secured, while at the same time there is an additional strengthening and bracing of the beams F F in place.

Each of the beams F F has on its inner face at itsfront'end and integral with its walls a plate forming the wearing-boss T for the couplershank. This boss serves to strengthen the said front end of the beam, which otherwise than for the ends of the ribs Q is hollow, as at W.

It will be noticed that the outer face of each of the draft-beams F F is plain, presenting no projection, and that the walls, ribs, bosses, and lug of each beam are integral therewith, so that formed as described the beam has great power to resist a strain in any direction that may be imposed upon it.

The beams F F are each of substantially uniform height, except at their front ends, where they are recessed for the countersinking of the head-block C and the carry-iron E. The outer faces of the beams when in position are substantially parallel, and the Walls thereof are of less width between the wearingbosses and the abutments of the pockets than in the rear of the latter, giving more space in front for the draw-bar, while at the rear greater strength is given to the connection of the abutting lugs. The removable plates X, as is obvious, hold the follower-plates and springs in place, and the removal of the nuts on the bolts G allows the removal and replacement of the springs and follower-plates.

While I have illustrated and described only one example of the physical embodiment of my invention, I do not intend to limit the scope thereof to such example, inasmuch as in practice changes and modifications may be introduced at will without constituting a substantial departure.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with the stringers A A, of two metallic draft-beams, each beam having a top wall 0, bottom wall P parallel with the top wall, ribs Q, said bottom wall, top wall and ribs Q extending inwardly from the vertical wall, walls or abutments M bounding the pocket L for the follower-plates, perforated bosses R intermediate the top and bottom walls and the ribs Q, perforated lug S, and bolts G passing through the stringers and bosses R; in substance as set forth.

2. The combination with the stringers A A, of two metallic draft-beams, each beam having a perforated lug S located in the rear of the pocket Lfor the follower-plates and adapted to form a stop for a coupler-yoke, atop wall 0, a bottom wall P broken away the length of the pocket, strengthening-ribs Q extending from the pocket L to the ends of the beam, and taking the strains and blows imparted to the abutments M, and bosses R between the top and bottom walls; the said beams being united by bolts K which pass through the stop for the coupler-yoke, and secured to the stringers by bolts G; and the lower portions of the pockets L L closed by a removable plate X detachably held in place by the bolts G, G, and nuts, which are located adjacent the pocket L; as set forth.

3. A metallic draft-beam having the top wall 0, bottom wall P, perforated lug S, abutments M, pocket L open at the bottom, ribs Q, hollow space Wat the froutendclosed by the top, bottom, end, and outside walls and by the wearing-boss T, and bosses R perforated for the reception of bolts G; the end of the said beam being adapted to be secured to the head-block by bolts passing through the hollow space W; as set forth.

4. Two metallic draft-beams each having a plain outer face with a recess Y, a top wall, a bottom wall, perforated lug S, pocket L open at the bottom, ribs Q, perforated bosses R, in combination with bolts K, stringers, bolts G, a removable plate X, and strain-rods J, each strain-rod being bent at the end and seated in a recess Y and the opposite end extended through the body-bolster and adapted to be attached to a needle-beam.

5. The combination of the two draft-beams width between said wearing-bosses and said abutting-lugs than in the rear of the latter; in substance as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
