CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No'. 753,626, dated March 1, 1904.

Application filed May 28, 1903.

To aZZ whom it may concern.-

Be it known that I, WILLIAM G. PRICE, a citizen of the United States, residing at New York, in the borough of Manhattan and State of New York, 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.

The present invention relates to improvements in car-trucks, and particularly to' such as are designed for use in connection with street-railway cars; and the object in view is the provision of aframe which is susceptible of formation from a single steel bar and which may be forged without welding, whereby cheapness and simplicity of structure is attained and strength and efliciency assured.

With this and other objects in view the in-' vention consists in combination, with axles and a bolster of the truck, of side frames, springs supported by said axles and carrying said. frames, transoms connectlng the frames on each side of said bolster, and springs carried by said transoms supporting the bolster.

It further consistsin combination, with suitable axles, of vertically-movable side frames:

connecting the same, means carried by the axles for guiding said frames, and a bolster supporting said frames.

It also consists in certain other novel con: structions, combination, and arrangement of parts, as will be hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 represents a view in side elevation of a cartruck embodying the features of thepresent invention. Fig. 2 represents a top plan view of the same.- Fig. 3 represents an enlarged detail perspective view of one of the bearing boxes. Fig. 4 represents an enlarged detail perspective view of one of the elliptic-spring hangers.

In carrying out the present invention I contemplate providing a truck having side frames of yoke shape engaging laterally-projecting guiding-lips carried by the bearing-boxes of the axles of the truck, each of said side frames being formed of one piece and transoms connecting the side frames and carrying an in- Serial No. 159,140. (No model.)

terposed bolster. By the provision of the integral formationof the side frames or yokes I obviate the necessityfor the use of a plurality of parts, and in the embodiment disclosed in the accompanying drawings I em ploy,in connection with suitable axles l 1,bearing-boxes, (indicated by numerals 2 2,) inclosing the-ends of said axles. Each of the boxes 2 is formed with laterally-projecting lips 3 3, leaving a vertical pathway therebetween, which pathway is filled by the respective side frames 4, each of which side frames is formed yoke shape,with the vertical portions 5 5 lying within said pathway between the respective pairs of lips 3, whereby said yoke will be guided in its movement. The side frames 4 have their ends connected togetherby end frames 6 6 and are connected. centrally together bytransoms 7 7, each of the said transoms being formed, preferably, of an angle-bar bolted at The elliptical springs 11 are of the common type and support a suitable bolster 12, extending transversely of the truck between the transoms 7. Each side frame 4. is provided with a suitable cap 13 near eachend of the upper horizontal portion of said frame for receiving the upper end of a coiled spring 14.. the lower end of which spring rests upon aseat15, carried by a laterally-projecting flange 16, extending from and formed integral with bearing-boxes 2 and projecting upon each side of a horizontally arranged connecting barv 17, which bar extends between dependingears 18, formed integral with and extending down wardly from the bearing-boxes 2. A suitable bolt or other securing means 19 extends through the ears 18 and the bar 17 for securing the parts together, the said bolts and bars retaining the bearing-boxes against any lateral movement, which accomplishes a very valuable function, as will be hereinafter-more fully described.

Of course it will be apparent that the cushion means can be rested upon the equalizingbar 17 in any suitable manner or may engage the said bar without any means interposed between them and the said bar.

Depending from each transom 7, near each end thereof, is a link 20, carrying a brakeshoe 21, designed to contact with the wheels 22, carried by the axles 1. A transverse bar 23 connects the links 20 on one side of the bolster 12 together and is itself carried by a brakelever 24, which lever is designed to be operated by any suitable draw-bar 25, the forward movement of the drawing-bar in operation moving the transverse bar 23 toward the wheels 22 for effecting the braking operation. The lower end of the lever 24 is pivoted, as at 25, to a link 26, provided with an interposed turnbuckle 27 and connected at its opposite end pivotally, as at 28, to the brake-lever 29, which lever is arranged on the opposite side of bolster 12 from lever 24, both of said levers being preferably arranged centrally of the truck. The lever 29 carries a transverse bar 30, which is connected with the respective links 20 at its opposite ends, so that when the lever 2 1-is moved for throwing the shoes 21 against the wheels upon its side of the bolster 12 the link 26 will cause the lower end of lever 29 to swing in the direction of the wheels upon its side of the bolster, whereby the bar 80 will be caused to move and swing the shoes 21, connected with the links 20,- to which said bar is attached, into contact with said wheels. It is to be observed that the weight of the car-body is supported by the bolster 12, resting upon the springs 11, carried by the transoms 7 and frames 4:, which in turn rest upon the springs 14, whereby a comparatively great pressure is borne by the seats 15, whereby the bars 17 are prevented from having any lateral or longitudinal play and through their connections with the cars 18 will prevent the wheels 22 from spreading, whereby the brakeshoes 21 may be caused to act much more effectually and quickly than could be accomplished were the said wheels free to spread apart slightly.

In operation any jarring of the wheels 22 will be absorbed by the springs 14 and the spring 11, the bolster 12 being free to move vertically between the transom 7 and the frames 4 being left free for vertical movement while being positively guided and limited against lateral play by the lips 3.

Although I have set forth the details of a particular embodiment of the present invention, yet it will be observed that many slight alterations may be made and changes as to the size and shape of the parts, and I wish it to be understood that I contemplate making any and all such changes within the spirit and scope of the invention.

It will be observed that the entire weight of the car is sustained by the equalizing-bar 17, and as such bar is fixed to the boxes 2, which boxes are provided with guiding-lugs engaging the pedestals of the frame 1, the said boxes will be positively retained against anylateral play or twisting action and held firmly in alinement with their respective axles.

As best seen in Fig. 3, the element which I have mentioned as a flange consists simply of a bar or piece of material formed integral with the box 2 and extending laterally therefrom in position for resting upon the bar 17 and may or may not be formed with parallel depending flanges for inclosing said bar, as desired, said flanges being preferable, as they effectually prevent lateral play of the element 16. The ears 18 are illustrated as continuous of and formed integral with the depending parallel flanges, so that a pair of ears or jaws is formed for inclosing each end of each bar 17. However, the cars 18 need not be made integral with the element 16 or even continuous thereof, but maybe formed in any desired manner, so long as they are made intogral with their respective box 2.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
