EDWARD S. MARSHALL, OF LOUIS, MISSOURI, ASSIGNOR TO THE MISSOURI RAILWAY EQUIPMENT COMPANY, OF SAME PLACE.

TRUCK END CASTING.

SPECIFICATION forming part of Letters Patent No. 587,266, dated July 27, 18 97.

Application filed April 29, 1897.

To all whom it may concern:

Be itknown that I, EDWARD S. MARSHALL, a citizen of the United States, residing in the city of St. Louis, State of Missouri, 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, in which- Figure 1 is a side elevational view of my improved truck end casting, parts being shown in section. Fig. 2 is an end view of my improved casting. Fig. 3 is a fragmentary detail view in perspective of one end of the top cross-bar. Fig. 4 is a detail View of a column-guide and a portion of the springseat. Fig. 5 is an elevational View of a modified form of end casting, showing the adaptation of the key-seat for the column-bolt. is an enlarged end view. Fig. 7 is a detail View of the key-seat.

This invention relates to a new and useful improvement in truck end castings; 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.

Generally stated, this invention may besaid to be an improvement upon the truck end casting forming the subject-matterof United States Letters Patent No. 569, 964, dated October 20, 1896, and granted to the American Railway Equipment Company, of East St. Louis, Illinois, assignee of Thomas Eubank.

In the above-mentioned patent the top cross-bar is cast integral with the columnguides, while the spring-seat is formed separate and bolted to the column-guides after the bolster and springs are in position.

In my invention the spring-seat is cast integral with and forms substantially thebotw tom cross-bar for the column-guides,' while the top cross-bar is cast separate and is adapted to be interlocked at its ends with cooperating parts upon the upper ends of the 001- v Fig. 6 7

Serial No. 634,383. (No modelfi said keys affording seats'for the reception of the heads of the colu mn-bolts,and an extended bearing-surface across the top arch-bar, and thereby serve to retain the arch-bar in proper relation to its seat in the top cross-bar should the col umn-bolt become broken or displaced.

In the drawings, A indicates the top archbar, B the lower arch-bar, O the tie-rod, and D the cross tie-rod, all of usual or well-known construction.

E indicates the column-guides, which are formed hollow and open at one side,(the outer,) while the top and bottom are closed by webs e, which are perforated to permit of the passage of the column-bolts E therethrough. The upper ends of these column-guides are recessed or notched, as shown, thereby forming ribs or flanges e, which are adapted-to cooperate with converse seats f in the upper cross-bar F.

G indicates ears projecting upward from the ends of cross-bar F, said ears being slotted,

' as at g, for the reception of a flattened key H, which key is formed with a seat It, in which the head of the column-bolt is adapted to fit snugly, so that it is prevented from turning.

Ears G are formed with strengthening webs or flanges g", the flange on one of said ears being cut-away, as at g, to permit of the passage of a cotter-pin h, which is adapted to be inserted through a perforation in the end of key II to lock said key in position.

I indicates the spring-seat for supporting the bolster-springs, said spring-seat being cast integral with the column-guides and forming substantially the bottom cross-bar of the end casting, said casting being substantially in the form of a letter U. In the under side of the spring-seat is formed a seat for the lower arch-bar, said arch-bar seat being extended beyond the springseat to beneath the column-guides.

J indicates the truck-bolster, and K the bolster-springs.

In assembling the parts above described the tie-rod 0, cross tie-rods D, and lower arch-bar are placed in position. The U-shaped casting is now placed in position above the archbar, the arch-bar fitting snugly in the seat in the under side of the spring-seat and lower ends of the column-guides. The bolster and springs are then placed in position, the springs being seated upon the spring-seat and the bolster fitting between the column-guides. Pressure is now brought to bear upon the bolster to compress the springs to permit the bolster to pass below the plane of the upper ends of the column-guides, when the top crossbar may he slid into position, as shown in Fig. 1. After the top cross-bar is secured in position the top arch-bar is fitted in its seat in the upper side of the crossbar, and the keys II are then introduced through their respective slots in the ears G and secured by the cotter-pins h. Thecolunin-bolts are now insertedthat is, passed downward through registering openings in the key-seats, top arch-bar, webs of the column -guides, and lower arch-bar, cross tierods, and tie-rod until the head of the bolt fits snugly in the key-seat, whereby the bolt is prevented from turning. A suitable nut is then screwed upon the lower ends of the column-bolts and turned up against the tie-rod until the parts are tightly locked against independent movement.

From the foregoing description it will be seen that an end casting is produced which is simple, compact, and when assembled possess'es the virtues of a one-piece casting, thus obviating the use of throughbolts; also, the key-seat, in addition to acting as a lock-nut for the column-bolt, presents an extended bearing-surface for the top arch-bar and serves to hold the arch-bar in its proper relation to the end casting should the columnbolt be removed or become broken.

In Fig. 5 I have shown an adaptation of my key-seat to the form of end casting shown in the herein-mentioned Eubank patent, wilh the addition of the strengthening-flanges for the ears G.

I am aware that minor changes in the construction, arrangement, and combination of the several parts of my improved end casting can be made and substituted for those herein shown and described without in the least departing from the nature and principle of the invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is.

1. The combination with the arch-bars of a truck, of column-guides, an integral crossbar connecting the lower ends of said columnguides, said cross-bar comprising a springseat and being formed with a seat for the lower arch-bar, and a removable cross-bar adapted to be interlocked with the upper ends of the column-guides, said cross-bar being formed with a seat for the top'arch-bar; substantially as described.

2. The combination with the arch-bars of a truck, of column-guides, an integral crossbar connecting the lower ends of saidcolumnguides, said cross-bar comprising a springseat and being formed with a seat for the lower arch-bar, a removable cross-bar adapted to be interlocked with the upper ends of the column-guides, said cross-bar being. formed with a seat for the top arch-bar, and columnbolts adapted to be inserted through registering apertures in the arch-bars, top crossbar and column-guides, to lock said parts in their proper relative positions; substantially as described.

3. The combination with the arch-bars of a truck, of column-guides, an integral crossbar connecting the lower ends of the columnguides, said, crossbar comprising a seat for the bolster-springs, a seat in the under side of said spring-seat for the reception of the lower arch-bar, tie-rods and cross tie-rods beneath the lower arch-bar, a removable crossbar con nectedto the upper ends of the columnguides, and formed with a seat for the upper arch-bar, ears on the ends of said cross-bar, keys adapted to be inserted through suitable slots in said ears, said keys being formed with seats for the heads of the column-bolts, and said keys being adapted to retain the upper arch-bar in its seat, when the column-bolt is removed, and column-bolts; substantially as described.

4. The combination with the arch-bars of a truck, of columirguides, a removable connecting-bar secured to their upper ends, into which connecting-bar the top arch-bar is seated, slotted lugs or cars extending up from the ends of the connecting-bar, and keys in said slots and above the top arch-bar5 substantially as described.

5. The combination with the arch-bars of a truck, of column-guides, a removable connecting-bar secured to their upper ends, into which connecting-bar the top arch-bar is seated, slotted ln gs or ears extending up from the ends of the connecting bar, keys in said slots and above the top arch-bar, said keys being formed with seats or pockets for the reception of the ends of the column-bolts, a combined cross-bar and spring-seat integral with the lower ends of the column-guides, said cross-bar being formed with a seat for the lower arch-bar and column-bolts; substantially as described.

6. The combination with the arch-bars of a truck, of an end casting arranged therebetween, said end casting comprising columnguides, a cross-bar connection between the upper ends of said column-guides, a springseat connecting the lower ends of the columnguides, and lugs extending above the top arch-bar, keys inserted in said lugs and on top of said arehbar, said keys being formed with a seat or pocket in their upper faces for receiving the heads of the column-bolts, and column-bolts; substantially as described.

In testimony whereof I hereunto atlix my signature, in presence of two witnesses, this 14th day of April, 1897.
