Application lefl July 29, 1904. Serial No. 218,638.

T all whom, t may concern:

Be it known that I, EDGAR PEOKHAM, residing at Kingston, in the county of Ulster and State of New York, have invented certain new and useful Improvements in Trucks, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to the construction of trucks.

One of the objects of this invention is to provide a truck of the general construction known in the art as the Master Car-Builders type, in which such changes are made as to obviate the necessity of using equalizerbars and result in a stronger, lighter, and

. easier-riding truck.

lbodiment of my invention.

Other objects .will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts, which will be hereinafter illustrated, and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings, which illustrate two of various possible `embodiments of my invention, Figure 1 is a side elevation of a truck embodying my invention. Fig. 2 is a cross-section of the same, taken on the line x x of Fig. 1. Fig. 3 is a side elevation of a portion of a slightly different em- Fig. a is a plan view of the embodiment shown in Fig. 1. Fig. 5 is an enlarged detail elevation of the pedestal shown in Fig. 1. Fig. 6 is a plan of the same. Fig. 7 is a cross-section on the line y y of Fig. 5. Fig. 8 is a cross-section taken on the line z e of Fig. 5.

Similar reference characters refer to similar parts throughout the several views.

It may here be noted that in former trucks of this general type it has been considered necessary to use equalizer-bars in order to attain the best results in the matter of strength and ease of riding. These parts are heavy and expensive and occupy so great a space upon the axle-boxes that any springs mounted thereupon are necessarily small.

In constructions of the general nature of that hereinafter described the above and other defects are remedied by supporting the truck-frame directly upon the axle-boxes by means of heavy spiral springs. Such an arrangement with its many advantageous features, including a long spring-base and a low-hung car-body, is rendered practicable by reason of the peculiar construction and arrangement of the several parts, as hereinafter described.

Another object is to provide a pedestal construction which shall be adapted to inclose heavy spiral springs and yet possess strength and stiffness to a marked degree.

Referring now to Figs. 1 and 2, A represents the wheels of a truck mounted upon axles B, having axle-boxes C. Positioned upon the latter are saddles 1, which serve to support pedestals 2 by means of spiral springs 3. These springs are preferably two in number upon each axle-box and extend into partially-inclosed recesses or chambers in the pedestals 2. I/Vith this construction it willbe noted that if one of these springs should break the remaining spring alone will tend to support the load which was borne by both of them, and thus prevent the entire disabling of the truck. Upon the outer projecting ends of pedestals 2 are mounted end bars 4:, having thereon the spring-supports 5 for outside-hung motors. It will be obvious that several of the features of this invention may be used in connection with a construction which permits of inside-hung motors or, if desired, in a trailer-truck, as hereinafter more particularly described. The legs of the pedestals 2 are connected by repair-pieces 6, and stretched between the lower ends of the inner legs on each side of the truck and secured within slots therein by means of bolts 7 is a tie-bar 8. Mounted upon pedestals 2 between the parallel flanges 9 and secured at its depressed central portion to tie-bar 8 is a truss or stiening member l0. A side bar 1l is supported at its ends upon pedestals 2, resting upon member 10 and secured to the same and to the pedestals by means of bolts 12. It may here be noted that the pedestals, side bars, and tie-bars, together with the stiffening member 10, form a light and yet strong and rigid truss construction for the side frame of the truck. Secured to the lower surface of side bar 11 is a plate 13, shaped substantially as shown in Fig. 4 and having two inwardly-projecting portions for a purpose hereinafter described. Extending from the lower surface of this plate to the upper surface of member 10 is a rectangular frame 14, preferably formed of one piece of metal. This frame is secured at its lower end by means of bolts 15 passing through IOO lIO.

Among the many advantageous features of constructions of the nature of that above described it may be noted that the peculiar arrangement of springs not only increases the length of the spring-base, thus lessening the tendencyto rock or gallop, but also, on account of the plurality of springs, decreases the effect of the possible breaking of one of them, as suoli an accident with this construction would not result in the dropping of the carbody or even prevent the running of the car. Moreover, as above noted, the bolster construction is not only light and rigid, but permits the same to hang down between the springs, and thus results in the desirable feature of a low-hung car-body. It will also be noted that as the axle-boxes are not encumbered by equalizer-bars larger spiral supporting-springs may be used than would otherwise be practicable.

may be used of such dimensions as safely to perform the functions of main carryingsprings and not act merely as auxiliary springs, as in many constructions in which spiral axle-box springs are used. The ease with which the several parts may be assembled and the security with which they are held in assembled position will also be clear to those skilled in this art. The structure of the pedestal also possesses marked advantages in the matters of lightness and stiffness of construction and the ease with which the several parts associated therewith may be assembled. lt will be noted that this lightness is attained without materially weakening the structure of the pedestal, the portions cut away being those which would be subjected to a relatively slight stress and the upper portion of the outer leg being preserved intact, thereby providing a strong and rigid support for the end bar and the parts resting upon the same.

' As many changes could be made in the above construction and many apparently widely di'Herent embodiments of my invention could be made without departing from the scope thereof, l. intend that all matter contained in the above description and shown in the accompanying drawings shall be interpreted as illustrative an d not in a limiting sense. I desire it also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention which as a matter of language might be said to fall therebetween.
