BLYE SCOTT, OF MEMPHIS, TENNESSEE.

TRUCK.

b all whom it may concern.'

Be it known that I, BLYE SCOTT, citizen of the United States, residing at Memphis, in the county offShelby and State of Tennessee, have invented certain new and useful Improvements in Trucks, of which the following is a specification.

This invention comprehends certain new and useful improvements in trucks for railway cars and the primary object of the invention is to provide a truck of this type in which both the side frames and the bolster and their related parts will be of simple, durable and light construction capable of being cheaply manufactured and vreadily assembled.

With these and other objects in view as will more fully appear as the description proceeds, the invention consists in certain constructions, arrangements and combinations of the parts that I shall hereinafter fully describe and then point out the novel features in the appended claims.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a perspective view of a bolster constructed in accordance with my invention; Fig. 2 is a longitudinal sectional view thereof; Fig. 3 is a transverse sectional View; Figs. 4 and 5 are fragmentary perspective views of parts of a bolster; Fig. 6 is a perspective view illustrating the bolster in its operative relation to the side frames of the truck; Fig. 7 is a detail view illustrating the parts of one of the side frames shown detached from each other; and, Fig. 8 is a detail side elevation illustrating a modificationhereinafter specifically referred to.

Corresponding and like p-arts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The bolster 1 of my improved railway truck is preferably composed of four main parts, which embodies two side pieces 2 of steel with angularly disposed ends 3, and two intermediate pieces or web portions 4 with angularly disposed ends 5 set back from the extremities so as to define flanges 6. In assembling these parts, the two longitudinally extending webs 4 are set back to back with their angularly disposed ends 5 facing outwardly in opposite directions, as shown and the two side pieces 2 are then placed Specification of Letters Patent.

with their ends 3 facing each other and extending over ends 5, the extremities of the ends 3 abutting against the flanges 6 so as to form a strong and light box-like structure with a double longitudinal web.

Fitted within the space between the side pieces 2 and the webs 4 are two truss supporting struts 7. Each of these embodies a substantially fiat plate on the upper side of which are two I-shaped tenons 8 spaced from each other as shown. The two ends of each tenon fit in the spaces'between the webs 4 and side pieces 2 and are securely bolted thereto, the space between the two Lshaped tenons accommodating the double web, as clearly illustrated in the drawing. On the opposite side of the plate of each truss strut 7 are two depending flanges 9, the lower ends of which are recessed as indicated at 10 so as to receive the truss rods 11. These rods are connected together at their inner ends by a turn-buckle or sleeve 12 and the outer ends of the truss rods pass through bolt holes formed for them in the overlapped ends of the side pieces 2 and webs 4, the nuts on the outer ends of the bolts thereby serving the double function of securing the truss rods in place and holding the outer sections of the bolster together.

13 designates the center plate which fits upon the upper side of the bolster 1 between the two truss supporting struts 7, the said center plate being also formed with spaced I-shaped tenons 14 fitting in and securely bolted to the side pieces and webs of the bolster. Each of the webs 4 is preferably formed with a crimped portion at its middle, the inner face of the crimp forming a recess facing a corresponding recess in the other web, so as to provide a substantially circular opening 15 extending through the middle of the bolster.

17 designates the saddles for the truss rods 11, said saddles projecting inwardly from the side pieces 2 and preferably formed integral therewith, as indicated in Fig. 2.

In connection with the bolster constructed as above described, the improved truck of my invention embodies two side frames, illustrated in Figs. 6 and 7. Each side frame embodies an upper arch bar 18, a lower arch bar 19, which latter is formed with a seat 2O for the bolster supporting springs, and a pair of column posts 21 interposed between the upper and lower arch bars 18 and 19. Each column post 21 is ar ranged to work within the iianges of a column post guide 22 bolted, riveted, or otherwise secured to the bolster at the ends of the outer side pieces 2, as clearly illustrated in Figs. 1 and 6. Each of the pieces forming the column post 21 is of substantially T- shape, as best seen in Fig. 7 and embodies a substantially horizontal member 23 on the outer end of which is formed a vertical member 24. This latter is adapted to abut against the inner side of the sectional journal box post 25, the two sections of which are formed as upwardly and downwardly projecting thickened portions of the ends of the arch bars. The part 24, in the embodiment of the invention illustrated in Figs. 6 and 7 also serves as a section of the journal box post and as a means for securing together the outer ends of the arch bars. The column post 21 in thisfform of the inven tion is formed with upper and lower tenons 26fitting within mortises 27 in the respective arch bars and secured therein by key bolts 28 as shown.

29 designates the bolster supporting springs seated on the plate or seat 2O of the lower arch bar.

As another form of my invention, reference is to be had to Fig. S, in which 18a designates the upper arch bar, 192L the lower arch bar, and 2la the column post. In this form of the invention, the column post 21a with its horizontal member 23a and vertical member 24, are formed as integral parts of the lower arch bar 19, and the vertical member 24a is recessed as indicated at 30, so as to form a scarf joint with the depending projection 251 so as to form a journal box post, bolts 31 passing through the parts, as indicated in Fig. 8 so as to secure the upper and lower arch bars together in a firm manner. In this modification, also, the column post 2lat is formed with a tenon fit-V ting in a mortise in the upper arch bar and a key bolt 28a extends therethrough to lock the parts.

From the foregoing description in connection with the accompanying drawings, it

will be seen that I have provided a very simple, strong and eicient construction of cail truck including a novel construction and arrangement of the parts, the. parts being scribed, a bolster comprising side pieces formed with inwardly turned ends, .web pieces interposed between said side pieces and formed with outwardly projecting ends set back from their extremities and deining flanges against which the inwardly turned ends of the side pieces are adapted to abut, the web pieces being disposed back to back, and means for securing the side pieces and webs together.

2. In a car truck of the character described, a bolster comprising a pair of webs provided with outwardly projecting ends, a pair of side pieces formed with inwardly turned ends overlapping the outwardly projecting ends of the webs, and truss rods extending at their ends through the overlapped ends of the webs and side pieces.

3. In a car truck of the character described, a bolster comprising a pair of webs provided with outwardly projecting ends, a pair of side pieces formed with inwardly turned ends overlapping the outwardly projecting ends of the webs, and truss rods extending at their ends through the overlapped ends of the webs and side pieces, the side pieces being formed with saddles upon which said truss rods rest, and struts secured to and depending from the side pieces and webs, thetruss rods extending across and being engaged with said struts.

l. In a truck of the character described, a bolsterl embodying a web and side pieces spaced therefrom in the direction of the length of the bolster, the webs and side pieces being formed with overlapping ends, truss rods extending through said ends, and truss rod struts formed with I-shaped tenons projecting up between the web and side pieces, the truss rods extending across and engaging said struts.

In a truck of the character described, a side'frame for a bolster, said side frame comprising an upper arch bar, a lower arch bar, column posts yinterposed between the arch bars and secured thereto, eachv column post embodying a horizontally extending member, and a vertical member at the outer end of said horizontal member, the arch BLYE SCOTT.
