Specification of Letters Patent.

Patented Sept. '7, 1915.

Application filed July 2, 1914. Serial No. 848,613.

To all whom it may concern Be it known that I, WILLIAM F. KmsnL, Jr., a citizen of the United States, and resident of- Altoona, county of Blair, State of Pennsylvania, have invented certain new and useful Improvements in Car-Trucks, of which the following is a specification.

My invention relates to cantrucks and more particularly to six-wheel trucks.

In the present form of equalizatiomdsvices it has been found necessary to locate the spring beams twice as far from the center axle as from the end axles, in a six-wheel truck, to accomplish proper equalization of the weight on the wheels.

The principal object of my invention is to arrange the equalizer bars on a six-wheel truck so that it will be possible to distribute one-sixth of the load to each wheel and to locate the bolsters and the springs therefor half way between the middle and end journal boxes. The advantage of this arrangement is that the same amount of space is available on both sides of the spring beam for brake head and shoes, permitting the shortest possible wheel base for the truck. The above and other objects and the novel features of my invention will be apparent from the following description, taken in connection with the drawings, in which Figure 1 is a plan view ofone-half of a truckcmbodying my invention; Fig. 2 is a view partly'in side elevation and partly in section taken along'the line 22 of Fig. 1; Fig. 3 is a longitudinal section on the line 3-3 of Fig. llooking in ,the direction of the arrow at the opposite side of the truck; Fig. 4 is across section taken on the line 44 of Fig. 1; Fig. 5 is a plan view and Fig. 6' a side elevation of the primary equalizer bar; Fig. 7 is a plan view of the secondary equalizer or saddle; Fig. 8 is a 1011- gitudial section taken on the line 8 8 of Fig. 7; Figs. 9 and 10 are respectively a plan view and a longitudinal section on the line 1010 of Fig. 9 of the spring seat carried by the primary equalizer bar; Figs. 11 and 12 are respectively a side elevation and end elevation of the center pedestal; Figs. 13 and 14 are respectively a side elevation and an end elevation of one of the end" pedestals; and Fig. 15 is, a horizontal cross-section on the line 15"15 of part of the pedestal shown in Fig. '13.

Referring to thedrawings, 20, 21 and. 22 designate the axles of thetruok upon which the wheels 23, 24 and 25 respectively are fixed. Side frame members made up of oppositely facing channel members 27 and 28 are riveted to the top surface and to lateral flanges 29-on the end pedestals P and to the top surface and lateral flanges 30 on the center pedestal P. The pedestals P and P are supported on the journal boxes and springs 31 located between cap plates 32 and the top of the journal box form a resilient support, the cap plates 32 being riveted to the opposite inner faces of the webs of the channel plates, 27 and 28. ,The pedestal jaws of the pedestals P and P fit the journal boxes in the usual manner.. v The pedestal P has lugs 33 at the lower'r'end of the jaws thereof and the pedestals P- have lugs 34 at the lower end of the inner jaw. The lugs 33 are each connected to 2. lug 34 by means of the tie rods 35 thereby forming a more rigid structure and bracing the pedestals. At the inner ends of the pedestals P there are hearing or guide surfaces 42' for the purpose of supporting wearing plates for the bolster guides.

Referring to Figs. 5 and 6 the primary equalizer bar 36 comprises a one-piece. steel castingdraving a hook 37 at one end to engage a plate 38 located on top of the journal box J supported on the center axle 21. The opposite end ofthe equalizer-bar 36 is drilled with a hole 39 and a bolt 40 passes through the hole 39 and through a hole at the lower end of a. link 41 which suspends that end of the equalizer bar 36 from the pedestal and thus indirectly from the beam made by the side frame members. It will be seen from Figs. 13, 14 and 15 that each of the pedestals P has an inwardly extending portion 42 which is hollow at 43 to receive the upper end of the link 41 and a gib 44 passes through a hole in the upper. end of the link 41 and through the holes 45 in the part 42 of the pedestal whereby the end of the equalizer bar 36 is hung from the frame member. Intermediate its ends the equalizer bar 36 is somewhat wider as at 46, where it is bent abruptly and on the inner side of the bent portion 46 there is a seat 47 with a projection OFFICE. I

48 to retain in place the spring seat 49 shown indetail in Figs. 9 andlO.

The spring seat 49 is grooved to provide the opposite sidcs-50 whereby .it straddles the equalizer bar 36 and a projection-51 in" the groove cooperates with the projection 48- on the bar 36 to keep the 'seat 49 place.

The top face of the spring seat 49 has rim flanges 52 against which the last spiral of the spring 53 fits and whereby the latter is held in place.

The spring 53 is shown as a double helical spring having a stifler spring on the outside and it supports one end of the bolster spring saddle or secondar equalizer bart54 shown in detail in Figs. i and 8. The secondary equalizer bar 54 is a one piece steel-casting and has at one end a cap 55 with depending rim flanges 56, the cap and flanges fitting the top of the spring 53 and the flanges retaining the same in place. The cap 55 is at the upper end of a right angle extension 57 of the secondary equalizer bar, the said extension being hollow to accommodate the spring on the interior thereof and the bar being inverted U-shape in cross-section at this end so as to straddle the primary equalizer bar. The opposite end 58 of the secondary equalizer bar is bifurcated, the bifurcations thereof having holes 59 to receive the bolt 40, whereby it also is fastened to the link 41 and is thereby suspended from the side frame member of the truck.

Intermediate its ends the secondary equalizer bar 54 has a horizontal portion 60 which is substantially U-shaped in transverse crosssection to straddle the substantially horizontal portion 61 of the primary equalizer bar 36. The top face 62 of the secondary equalizer bar forms a supporting surface for the elliptic spring 63 which carries the bolster 64 atone end, it being understood that the bolster issupported at its other end by a similar construction. The primary and secondary equalizer bars are directly beneath and in line with a center line through the members constituting the side frame of the truck and the support of the spring 63 is in the same plane.

The bolsters 64 on opposite sides of the center axle 21 are connected by a suitable stiffened bridge member 65, the ends of which are riveted to each one of the bolsters. The bridge 65 extends across the transverse center line of the truck and has lates riveted thereto, whereby the car b0 y may be pivoted at the center of the truck and supported by the bolsters 64: in the usual man From the foregoing description it will be apparent that the load on' the truck is equally distributed to the six wheels thereof by the combination 0. the rimary and secondary equalizer bars, as iss own. Further- ,more, the springs which support the bolsters are located half way between the center and end axles leaving more room for the brake heads and shoes. This is a decided advantage in the clasp brake construction here in shown but made the subject-matter of a sepit rate ajpplication.

hile have shown and described the construction in detail it is to be understood that the inventionis not limited to the exact details as they may be varied to meet 'different requirements.

Having described my invention what I claim and desire to secure by Letters-Pat'- ent is,
