Specification of Letters Patent. Patented Aug, 15, 1916,

Application filed June 20, 1916. Serial No. 104,662.

' To all whom it may concern:

Be it known that I, EDWIN E. SLICK, a

citizen of the United States, residing in the a borough of Westmont, in the county of Cam bria and State of Pennsylvania, (whose postby cold upsetting. This method of securing office address is J ohnstown, Pennsylvania,) have invented certain new and useful Improvements in Car-Trucks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to Which -.it appertains to make and use the same.

My invention relates to improvements in car trucks with particular reference to those which are used for railroad cars and are particularly adapted for use in connection with the heavy types of freight cars.

My invention also relates particularly to the construction and arrangement of the side frames for car trucks which I make of wrought or rolled steel, thereby providing a material which is best adapted to withstand the loads, shocks and impacts to which it is subjected in severe service. By constructing my truck frame of rolled steel, 1 provide material which, by its method of manufacture, inspection and tests, is known to be solid and integral throughout each art of its section and which may\ be of desired qualities and of any strength required, so that each part is best adapted to withstand the stresses to which it will be subjected in use. I also preferto secure the parts together by means of rivets which are upset when cold, in the holes provided therefor, and theheads, formed, at the same time,

the parts together works or flows the rivets to stresses and strains beyond their elastic limit when cold, and pinches and clamps the attached parts very firmly together so that no stresses less than the increased elastic limit of the material due to. said cold working, can affect these parts in use. By this means I provide with the same amount of material, a much stronger junction than can be accomplished by means of hot driven rivets which are upset by stresses very much less than cold driven ones in the ratio of about 1 to 20.

I preferably construct the lower member of my truck frame of steel, rolled or pressed into trough-sections, the intermediate ortion of which is spaced apart from t e upper member'a considerable dis tance and with integral inclined portions extending upwardly toward the upper member and thence extending substantially horizontal at each end, thereby forming portions with broad fiat lower surfaces comprls ng the web portions of the troughsectlon whlch are well adapted to rest upon the journaLboXes. I prefer to place this lower member with its flanges extending upwardly and secured to side plates by means of cold-driven rivets, as heretofore described.

I also prefer to arrange the upper member which is of section similar to that of the lower member, with its flanges extending upwardly and secured to the side plates by means of cold-driven rivets. I provide side plates on each side of my truck frame, each of said plates being integral and provided with a large central opening adapted to receive the bolster, these plates being secured to the side flanges of the top and bottom members by cold riveting. Around the central opening I provide a member of bent angle section 'to conform to the outline desired and secured to the side plates and the lower and the upper member by rivets. Attached to,the upper portions of the insides of said bent angle members and side plates,

I provide trough-shape portions extending a short distance inwardly of the opening and adapted to form guides for the bolster, the lower part of the opening being large enough to admit the bolster with integral guide lugs thereon, which, after being inserted through the lower part of the opening, is moved upwardly and the springs set below it in final position. I also provide seat plates for the bolster springs, and also other members corresponding to spring planks, which in this case are shown as angles, extending from the truck frame on one side of the car to that on the other, to square the trucks and hold the frames together. I also provide the usual bolts for securing the journal boxes in place, holes being provided for this purpose through the end portions of my truck frame. I also socure to the truck frame, brake hanger carriers which are also formed of steel and securely riveted to the frame.

Having thus given a general description of my invention, I will now refer to the annexed sheet of drawings in which like characters refer to like parts.

Figure 1 is a side elevation of a railway car truck, provided with a side frame embodying my invention; Fig. 2 is a vertical longitudinal sectional elevation of my improved side frame; Fig. 3 is a top plan view of the side frame; Fig. 4 is a vertical transverse sectional elevation taken on the line IVIV of Fig. 2, and Fig. 5 is a sectional elevation taken on the line VV of Fig. 2 drawn on an enlarged scale.

Referring now to the various characters of reference on the drawings: 1 represents the upper member or arch bar of my side frame which is formed of trough or channel shape, rolled or pressed as desired, the flanges of the same being shown as projecting upwardly; the inverted arch bar-is indicated as 2, which is of section similar to the upper arch bar and is also arranged with its flanges projecting upwardly, the lower portion of this arch bar extending substantially horizontally, spaced apart from the upper member and provided with the diagonal or inclined portions 3, as illustrated, and with the horizontally-extending end portions 4, as shown; 5 and 6 are each the integral side web plates of which there are two to each truck frame, one on each side of the arch bars and secured thereto by cold-driven rivets, as shown. Each of these side Web plates is provided with a central opening, as shown, to receivethe bolster and are reinforced around their edges adjacent to said opening by means of the bent angle reinforcement or truck columns 13, one of these being on each side of the side frame. At the ends of the truck I provide the holes 7 and 8 in the web portion of the upper arch bar 1, and the holes 9 and 10 in the smaller portion of the lower bar,

the flat ends of the web of the inverted arch bar being adapted to receive the journal box bolts 11 and 12, and in this connection it should be noted that these parts are so arranged that all the journal-box bolts are of the same length and size, which conduces to ease of construction and repair. The bolster spring seat is composed of a steel plate 14, which is mounted on and riveted to the lower portion of the truck column or-reinforcing angles 13, as shown. The spring planks are illustrated in this case as composed of two angles 15, which are riveted to the column guides, as shown, and extend from one side truck frame to the companion frame on the other side of the truck for the purpose of squaring and holding the two portions together. Between the inwardly projecting legs of the angles 15, I place and secure a filler plate 16 for the purpose of forming a level surface to receive the bottom spring plate or the bolster springs 17, which latter are illustrated as of the usual helical type. The bolster 18 may be of any usual type provided with guides at its end portions, adapted to fit around the column guides 19. The column guides 19 are formed, as illustrated, of shallow troughshape plates secured by rivets countersunk on the outside to the member 20, which member 20 is of trough-shape with its flanges extending inwardly between the opposing pair of truck columns and side plates and riveted thereto, as illustrated- The portion 19 is adapted to serve as a wearing plate and can be easily replaced at any time on account of the wear due to the motion of the bolster against the same. I also provide a brake hanger carrier which is illustrated as 21, composed of a bar of steel of shape shown, riveted to the truck frame as particularly illustrated in Fig. 5, the outwardly projecting portion being adapted to receive a brake hanger. I also provide pedestal tie-bar brackets 22 secured to the diagonal or inclined webs of the inverted arch bar, as illustrated, and the pedestal-tie bars 23, are

secured to the brackets by rivets and to the journal boxes by means of the bolts 11 and 12, as customary.

As illustrated in Fig. 4, I prefer to cut away the outwardly extending portions of the vertical legs of the truck columns or reinforcing angles, making them of tapering form, smaller at the top than at the bottom, but I may also make them parallel, if

desired.

hearings on the journal boxes. I also prefer to have the flanges of the upper arch bar, which is also of trough section, extend upwardly for ease of riveting the same in place, as the riveting machine can easily take hold .of the rivets in these outstanding portions. The riveting of the lower arch bar can also be easily accomplished before the upper one is put into place, as in this case the riveting machine can be inserted in the opening between the side plates.

It should also be noted that openings of substantially triangular shape with rounded corners are provided on each side of the bolster opening, for the purpose of lightening the construction and affording means of access to the interior for the purpose of construction, inspection or repair.

Although I have described and illustrated my invention in considerable detail, I do not wish to be limited to the exact and specific details thereof, as shown and described, but may use such modifications in, substitutions for, or equivalents thereof, as are embraced Within the scope of my invention, or as pointed out in the claims.
