TRUCK-END CASTING.

SPECIFICATION forming part of Letters Patent No. 569,964, dated October 20, 1896. Application filed July 15, 1896. Serial No. 599,234. (No model.)

To all whom it may concern:

Be'it known that I, THOMAS EUBANK, a citizen of the United States, residing at the city of Little Rock, in the county of Pulaski and State of Arkansas, have invented a certain new and useful Improvement in Truck-End Castings, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, wherein- Figure 1 is a side elevational view of my improved truck-end casting. Fig. 2 is an end view of the same. Fig. 3 is a detail view of the column-guides and spring-seat, only a portion of the latter being shown, however.

' Fig. 4 is a slightly-modified form inwhich the spring-seat is dispensed with, and a springplank or sand-board is shown in its place.

This invention relates to a new and useful improvement in end castings for trucks; and it consists in the construction, arrangement, and combination of the several parts, all as will hereinafter be described, and afterward pointed out in the'claims.

In the drawings, A indicates the top archbar, B the bottom arch-bar, O the tie-bar, and D the cross-tie bars, all of such parts being of any ordinary or approved construction.

E indicates the column-guides, which are 0 open at one side, the outer, the bottom, and top being closed by webs e and f, through which pass the column bolts G. The top walls of these column-guides are connected, forming a top cross-bar F, in which the top 3 5 arch-bar Ais seated, said top cross-bar being formed with flanges or ribs at its sides to form said seat. Extending upwardly from the col umn-guides and at the ends of this top cross bar are ears H, which project above the top 40 arch-bar, said ears receiving rods or bolts I, which are also above the top arch-bar. This I consider an important feature of my invention, as these bolts or rods I take the place of the column-bolts should said column-bolts become broken or lose their nuts, as very frequently happens in practice. Under such a condition the bolts or rods I would hold the column-guides up against the top arch-bar and retain the parts in position. The col- 5o umn-guides, being connected at their top by the cross-bar F, will not get out of alinement.

Thus it will be seen that even if the columnbolts were entirely removed the truck would still be serviceable.

The column-guides, with their top crossbar, are substantially of an inverted U shape, and secured between the lower ends of the vertical legs, or at the lower ends of the column-guides, is a spring-seat J for supporting the bolster-springs. This spring-seat is substantially T- shaped in cross-section, and is formed at its ends with ears j, extending on each side of the column-guides, to which they are secured, as will hereinafter appear. The base of the T is formed with side flanges or ribs which form a seat between them for the lower arch-bar N. Suitable strengthening-websj' brace the top of the seat.

K indicates the truck-bolster, which is supported at its ends by springs L, said bolster having lips or ears k on each side of the column-guides to guide the bolster in its vertical movement.

In assembling the parts the tie-rods O and D and the lower arch-bar are placed in position. The spring-seat is arranged on the archbar, the springs and bolster on top of that, and the column-guides now straddle the bolster and fit between the ears j of the springseat. The top arch-bar is now arranged between the ears H, and the column-bolts passed down through the respective openings made to receive them. The springs L not being under tension, the lower arch-bar will not be seated in the lower ends of the column-guides, and therefore the nuts on the lower ends of the column-bolts have to be turned up to bring the parts into proper position. \Vhen the parts are thus brought together, boltopenings in the ears j of the spring-seat and near the lower ends 01": the column-guides register, so that a bolt or rod M may be passed through. This bolt or rod M, together with the column-bolts, holds the springs L under tension, and should the column-bolts break 5 or be removed after these bolts M were once in place said bolts M would serve to main tain the proper relation between the column guides and spring-seats by preventing inde= pendent vertical movement of either and by roe tying the lower ends of the column-guides against any spreading tendency.

In Fig. 4. I have shown a slight modification or an adaptation of the column-guides having the top cross-bar to a spring-plank or sandboard. I11 this form the spring-seat is not used, but its place is taken by a spring-plank or sand-board N, which is secured to the lower ends of the column-guides by suitable bolts passing through ears 0, projecting laterally from the lower ends of said columnguides. In this modification ears P may also be provided at the lower ends of the columnguides, through which pass bolts Q under the lower arch-bar. This feature not only gives strength and adds rigidity to the structure, but affords a support for the lower arclnbar should the column-bolt become broken.

The operation of the parts is substantially the same and they are assembled in the same way, that is, the springs are placed under tension by the column-bolts until the ears on the column-guides are in proper position rela tive to the spring-plank, when bolts are inserted to secure the parts together. In this form, after the parts are all assembled if the column-bolts should become loose, broken, or even removed the truck would still be serv iceable.

There are many advantages incident to both of these constructions, chief among which are the rigidity it gives to the truck as an entirety, its simplicity, compactness, cheapness, and safety. 7

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is- 9 1. The combination with the arch-bars of a truck, of column-guides formed with ears or lugs which extend above the top arch-bar, and bolts or rods in said lugs or ears and on top of the top arch bar; substantially as described.

2. The combination with the arch-bars of a truck, of column-guides formed with a c011- necting-bar at their upper ends in which the top arch-bar is seated, lugs or cars extending up from these column-guides or cross-bars, above the top arch-bar, bolts or rods in said lugs, a spring-seat to which the lower ends of the column-guides are secured, and columnbolts; substantially as described.

3. The combination with the arch-bars of a truck, of column-guides whose upper ends are connected, said connection forming a seat for the top arch-bar, lugs II extending up above the top arch-bar, bolts or rods I in said lugs, spring-seats having ears extending on each side of the column-guides, and bolts or rods which pass through said ears and columnguides; substantially as described.

4. The combination with the arch-bars of a truck, of column-guides formed with ears or lugs which extend above and below said archbars, respectively, and bolts or rods in said lugs or ears for supporting the parts in the event of the column-bolts breaking or becoming loose; substantially as described.

In testimony whereof I hereunto afiix my signature, in presence of two witnessses, this 15th day of June, 1890.
