JOHN C. BARBER, OF ST. PAUL, MINNESOTA.

CAR TRuCK.

SPECIFICATION forming part of Letters Patent No. 573,636, dated December 22, 1896.

Application filed April 29, 1896,

To all whom/it may concern.-

Be it known that I, JOHN C. BARBER, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Oar-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 that class of cartrucks wherein the truck-bolster is mounted with freedom for vertical and lateral motion, and has for its object to improve the construction with a view of increased economy and efficiency. I

To these ends my invention comprises the novel devices and combinations of devices hereinafter described, and defined 'in' the claims. 5

My invention is illustrated in the accompanying drawingsavherein, like letters referring to like parts throughout the several views- Figure l is a side elevation of my improved truck. Fig. 2 is a plan view of one half of the truck, the other half being broken away. Fig. 3 is a vertical section, partly on the line 03 00 of Fig. 2 and partly in a vertical plane, through the center of the truck-bolster and one of the side frames. Fig. 4 is a perspective view, with some parts broken away, showing one of the side frames and parts cooperating therewith. Fig. 5 is a perspective View, with some parts broken away, showing one end of the truck-bolster with some parts removed and others broken away. Fig. 6 is a detail in perspective, showing one of the bolster end caps or filling-pieces removed. Fig. 7 is a detail in horizontal section, taken through a portion of the truck-bolster on the line x of Figs. 1 and 3. Fig. Sis a detail in plan. showing one of the movable plates which are carried with thebolster in its lateral movement 5 and Fig. 9 is aview in horizontal section corresponding to Fig. 7, but illustrating a slight modification in the form of the guides for the movable bearing-plates.

For the purposes of this case the details of the side frames of the truck are immaterial. The truck-frame may be of any suitable construction so long as the truck-bolster is mount- Serial No. 589,589. (No model.)

ed thereon with freedom for vertical and lateral'movement.

In the truck illustrated in the drawings, 0. represents the wheels; a, the axles; (L2, the journal-boxes; a the journal-box guides, and (t the tie-bolts, working through said guides a and the bars I) b b which together constitute the side frames of the truck. Of the said side-frame bars I) b b the upper member I) is of channel form and the other two members I) and b are plain bars, as best shown in Figsib and 4..

lhe transoms c are shown as of channelbar form and are riveted or otherwise secured to thebolster columns c. The said bolstercolumns a are also composed of channel-bars and are rigidly secured by gussets o to saddle-platesc of channel form, which rest upon the side-frame bars I) and b Column-bolts c extend through all the parts I) b b and c c c for rigidly securing the same together, relative to each other, in their proper working positions. The said transoms c, bolstercolumn 0, and saddle-plate c are conveniently made from channel-bars of the same size, with the inner flanges of the column 0 cut away to permit the transoms to be seated against the bolster columns. The saddleplates 0 are'cut away or notched at their ends to aiford the necessary clearance for the inclined parts of the truss-bars b.

Onthe saddle-plates 0 rest channel-bar roller-bearing plates f, which are of the proper size to fit against the bolster-columns c, with their flanges engaging over the flanges of the said saddle-plates 0 In this way the said bearing-plates f are held in a fixed position. Roller-bearings f rest in concave seats extending longitudinally of the said fixed bearing-plates f. On the said rollers f 'are mounted movable plates f which have on their under surface concave seats engaging with the rollers f and have on their upper surface springseats f Springs f rest on the said plates f and on the said springs rest shimming-blocks f which support the bolster. The said bolster is composed, as shown, of channel-bars g,'connected by the center plate g, end cross-ties g and g and end caps g, which fit between the ends of the channel-bars and the tie-bars g and are riveted or otherwise rigidly secured thereto, as shown in Figs. 1, 2, 3, and 7. The channel-bars g, of which the bolster is made, are preferably set with their flanges facing inward or toward each other, and near the outer ends of the bolster the lower flanges of the said channel-bars g are cut away, as best shown in Figs. 3, 5, and 7, so as to afford clearance for the vertical movement of the bearing-plates f and the bolster relative to each other. As shown in Figs. 1 to 8, inclusive, the said movable bearing-plates f are provided with notches f and the bolster channel-bars g are provided with vertical guides g cooperating with the said notches f to carry the said plates f with the bolster in its lateral movement, while permitting the bol ster to move up and down in respect to said p ates- I th 'modifiea ion shown in F g- 9 the substi u movable hearing=p etes h are repre= sen ed as co per t ng with ve tieal guides of angle iron form, ri t d or otherwise. s cure to h bolster ehannel be g an em gaging w th he eo ne of the sai plates It must e o ious th t the sai movable p ates f 2 migh be held and gui ed in espe t to the bolster in any other suitable way.

The sh mming b ook f a e s own tie o he olster y nu te bolts f, passing rough he said blocks an the ti a s g of. he said olster The said slimming-blocks f ar also repr sente as provided with plates f on their under ur ace for resting on. he pr ngs f, an th m vable bearing-plates J" are represen ed a ied to the s immihs locks 5 by eentra bolts f", arr ec y the plates and working t ough the plates f th th ir heads o a le i ent al s ot f formed in the blocks f as best shown in,

Fig. 3.

W h he on rneti n above described the movable pla es f the springs. f and the 11imm e= ke f are carried, i h the olster in its lateral movement, while at the same time the said parts serve to support the bolster from the truck-frame with freedom r e t ea mov ment on t e sp in f In is v t ca vement of the bolster the mova e b arins p e f est constantly n the r ll eb ar ng f, with the gui es g of the lster engag g the n eh f or other equiv alent sh eees of the said. plates f Hence per ectedo s a f rded for the spri g acon of t e bolete I virtue of the fact that he mo ab e ea iheplat s f and the springs. f are ear i d w th the bo s er in its lateral mov ment, a abo e' descri e it must be obvious hat he tors onal s ain on the springs f is avoided. Otherwise stated, the springs J" occupy a eon teh position in the rtica plane i e pect to th holster and he p ate f on which th pr n rest, The ar and tearef the springs is therefore very eat y r duc d, as oompared. with the eon= uetiohs hi herto used und the lateral mo o Th s improv ment in the spring action is obtained without detracting in the least from the freedom of the bolster for lateral movement on its, roller-bearing. The said roller-bearingsf and their cooperating bearing-plates f f are by my present invention set in a somewhat difierent relation to the bolster-supporting springs, but in respect to the lateral motion of the bolster serve substantially the same function as where shown in my several prior patents, Nos. 370,758, 383,688, 433,063, 506,460, and 528,844. In none of my prior patents, however, were any of the bearing-plates mounted so as to permit vertical movement of the bearing-plates in respect to the bolster.

I believe that I am the first to provide any kind of construction whereby the bolster-supporting springs are carried with the bolster in it lateral movements, while at the same ime having their bases of: resistance on the trnektframe or supp rting the bolster with eedom for spring-cushioned vertical movemeet, and I desire herein to claim. the same in the broadest possible way as a pioneer inventionhe shimn hg blocks f 5 a e pr ra made o ood, but may be of any suitable mater al, and serve to a ford a ready means fo adjusting the holster and the carbody to i ferent h ghts by simply inserting subet tute shimming-blocks of the desired thickness.

The bols er may be regarded as provided near its en s ith pockets for receiving he springs, shirnming-bloeks, and the movable members of the bearing-plates.

It will be understood, of course, that the detai s of the construction m gh be a ed in many ways without departing from the spirit of my invention.

It should be further noted that the concave form of the roller-bearing seats insures the centering of the bolster in its normal position.

What I claim, and desire to secure by Letters Patent of the United States, is as follows:

1, The combination with a truck-frame, of a bolster mounted for both vertical and lateral movements on the same, as a base of re.- sistance, base-plates carried by and fixed against lateral movement with respect to said bolster, but free for vertical movement thereon, and springs between said base-plates and said bolster, substantially as described.

The combination with a truck=frame and it bolster mounted thereon with freedom for lateral and vertical movements, of fixed roller-bearing plates on the truck fra ne, rollers on said fixed plates, movable bearingplates on said rollers, and bolster-supporting springs on said movable plates, with said mov able plates and said springs carried with the bolster, in its lateral movement, but permit ting vertical movement of the bolster, in respe'ct to the plates, substantially as de scribed.

33. The combination with a truck frame, of a truck-bolster, provided with pockets near its ends, roller-bearing plates fixed to the frame, rollers on said fixed plates, movable bearing-plates on said rollers, bolster-sup porting springs on said movable plates, and vertical guides, in the pockets of said bolster, engaging with said movable plates, whereby the movable plates and the springs are carried with the bolster, in its lateral movement, while permitting the vertical movement of the bolster, in respect to said plates, substantially as described.

4. In a car-truck, the combination with the side frames, of the fixed bearing-plates f, the roller-bearin gs f the movable bearing-plates f the springs f", the shimming-blocks f and a bolster provided with pockets, for receiving said parts f and f and provided with guides cooperating with the plates f substantially as and for the purpose set forth.

5. A oar-truck bolster, composed of the channel-bars g, cross-ties g g and end caps or filling-pieces g and having pockets in its ends equipped with vertical guides, in combination with the fixed bearing-plates f, the rollers f, the bearing-plates f, the springs f", and the shimming-blocks f all arranged, for cooperation, substantially as described.

6. The combination with the bolster-columns c and the saddle-plates c of the gussets 0 binding said parts together and reinforcing the same, said parts being formed of separate pieces and united by rivets substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.

JOHN C. BARBER.
