To all whom it concern):

Be .it known that 'I, ALLEN EDWARD OSTRANDER, a citizen'of the United States,

residing at Paterson, New Jersey, have invented a certain new and useful Im rovement in Car-Trucks, of which the fol o such ' is a full, clear, and-exact description,

as will enable others skilledin the art to which it appertains to make and use the same, reference being had'to the accom- Eanymg drawings, forming'part of this specication, in whic Figure 1 is a plan view of" a car-truck constructed in accordance with my invention.

Fig. 2 is a side elevation of said truck, showing the preferred form of equalizing device. Fig. 2 IS .an endview of a' portion of the the pedestal-tie-bar braces. Fig. 5 is a detail perspective viewshowing the manner of connecting the and piece and side frame. of the truck together, and Fig. 6 is an en larged transverse sectional view taken through the center of'the truck. I

This invention relates to car-trucks.

, One object of my invention is to providea car-truck in which the frame is constructed in a novel manner from commercially-rolled shapes, and another object of my invention is to provide a novel means for e ualizing the bearing of'the truck-frame. on t e journ'al-boxes.

Referring to the drawings, whichrepre sent the preferred form of my invention, -1

b desi'glrliates the side frames of the truck,

whi consist of I-beams', although channels could be used, desired. The 'end pieces 2 of the truck-frame consist of angles arranged with their horizontal legs projecting-inwardly and in the same plane as the top flanges -o the side frames 1. As

shown in Fig. 5, the horizontal leg of the end piece angle 2 is cut away, so that the vertical leg of said angle can butt against the web of the I-beam' 1, and these two,

members are connected together by an L- I shaped bracket 3 and by a gusset-plate 4,

iseeured' to th e'top flanges of said members,

' the bracket 3 bearing upon the inner faces of said members. I

The pedestals 5. are constructed at their upper ends to incase the bottom flanges of the l' beam side frames and are secured to the webs of said beams by rivets 6, which extend through vertical flanges 7 on the pedestals. Each pedestal-tie-bar brace is connected at its 0 p'osite ends to the side frame 1, and said braces referably consist of a number of angles. The angle 8, which forms the central section of said brace, is secured at its 0 po'site ends to the inner legs of the pedesta s and isarranged with its horizontal leg projecting inwardly. The end ,sections of the pedestal-tie-b'ar brace consist of straight angles 9, arranged with their horizontal legs projectin inwardly and inclinedangles 10, connecte to the an les 9 by rive-ts 11 and arranged with t eirv horizontal legs projecting outwardly, the angles 9 being connected to the outside legs of. the pedestals andthe angles 10 bein bent at their upper ends to form horizonta portions which are connected to the bottom flanges of the l-beams 1. vShort angles 12, arranged with their horizontal legsprojecting outwardly, extend across the 0 en ends of the pedestals and .are detacha 1y connected to the vertical legsof the angles 8 and 9 by means of bolts. 13. By arranging the angles 12 and the angles 8 and 9 so'that their horizontal legs PIOjBCt in opposite directions, a very wide bearing-base is provided for the lower ends of the edestals and the journal-boxes 14, the legs 0 I the pedestals being secured to the horizontal legsof thea les 8 and 9 b means of faste devices. ag mdicated in 1. The tie-l iii i' brace, on the opposite'sides' of the truck are connected toget er by means of transversely-extending angles 15, the horizontal legs of which projeot inwardly in-the same plane as the hori zontal legs of the angles 9, to which they are connected by gussets 16, said an les also being fastened together by L-sha e brackets .17,-secured to the inner facesp the vertical legs of'said angles, as shown in Fig. 5,

the horizontal legs of the angles 15 being,

cut away to permit the endsof said angles to butt against the vertical le s of the angles 9. At thecenter of the true intermediate the pedestals are two transversely-extending angles 18, which are secured at their op osite ends to the angles 8.by means of L-s aped brackets, (shown in dotted lines in Fig. 2,) the horizontal legs of the angles 18 also being cut away so that the'ends of said angles can butt against the vertical legs of the angles 8. The bolster of the truck-frame preferabl consists of two channels 19, arrangedwit their horizontal legs projecting in opposite directions and connected at their opposite ends b 'means of ]-shaped brackets to the we s of the I-beam s1de frames, the top flanges of the channels 19 lyin in the same being riveted to the to "flanges of the side horizontal plane as the top anges oi the I-beams 1 and being cut away, as shown in Fig. 6, so that the ends of the webs of said channels can butt against the websof the I-beams 1.

The top plate 21 of the bolster, to which the center and side bearings 22 and23, re'

spect'ively, are connected, is riveted to the top flanges offthe channels 19 and also to the top flanges of the side frames 1, and triangular-shaped grisset-plates 24 are provided to further strengthen the connection between the bolster and side frames, said gusset-plates frames and to the top anges of the channel 19 and late21, upon which they aresupenimpose as shown in Figs. 2 and 3/ The bottom plate 25 of the bolster is riveted to "the lower flanges of the channels L9, and at the center of the bolster are braces which consist oi short channelsha ed pieces 26, arranged between the channe s 19, to the webs ofwhich they are riveted, as shown in dotted lines in Figs. 1 and 6.

The means for equalizing the bearing of the truck-frame on the journal-boxes consists of-equalizer levers or bars 27, fulcrumed on thejournal-bxes 14 and connected at their 0 posit e ends byyielding' means to the :truckame. l 4 1 i In the preferred form of m invention, as shown in h ig. 2, the outer en of each equal-. izer-bar is provided with a sprin -seat 28, which sup orts a coiled spring 29, having its upper end resting in a spring-seat 30, fas-- The inner ends of tened to the side frame 1. the equalizer-bars on. each side of the truck are connected, by means of links 31,, to a semi elliptical spring 32, mounted in a bearing 33, depending from the side frame 1', thereby producing a very simple means for equalizing the bearing of the frame on the journalboxes, said boxes being preferably provided with a rib 34, whichenters a recess in the underneath side of the equalizer-bar to prevent it from shifting on the "Ollfllfil-bOX.

acts as 'a crum for the spring 32, to one side or the other of'the center line the tr'acti-ve pow-er on either pair' ofi wheels of the track can be increased, as the change locatienof va-. rying the osition of t e bearing 33', which this fulcrum will tend to throw. more weight on one pair or the other.'

In the form shown in Fig. 3 v tical spring 32 'isreplaced 1; a bar 35, provided at its opposite ends with seats 36;, which receive coiled springs 37., that are su ported by seats 38 on the inner ends of the are 27, the inner ends of said bars preferably curving downwardly, as shown in -Fig. 3.
