To all whom it may concern: y,

Be it known lthat l, Joins C. BARBER, a

citizen of Vthe United States, residing at Chicago, in the countyy of Cook and State of Illinois, hare invented certain new and useful Improvements'in Car-Trucks; and l do hereby declare the following to be a full,

clear, and exact description of the inventionsuch as will enable others skilled in the art to which it appertains to make and use the same. y.

My present invention has Ltor its object to proyide an improved car truck especially adapted for railway service and, to this end,

-it consists' of the novel devices and combina- Y tions ot devices hereinafter described and defined in the claims.

soin seats 3, said castings being formed, as

shown, with outwardly extended vrectangular Hanges that surround and form parts of these transom seats.

rlhe transoms l are in thc"form of heavv castings of hollow form, preferably recytangular in cross section. The rside frame castings and this transom are preferably .steel casting. The ends of the transom are reduced in vertical dimensions, so that they may be inserted into the seats 3 of the side frame castings with considerable clearance and, at the lower portions of their extreme ends',- they are vit'ormecl with downturned lool; tlanges 5 that are adapted to closely engage and interlock with the lower flanges ol saidseats, as best shown in Fig. 2. The shoulders formed by the reduced ends or" the transom engage the inner sides ot the side frame castings l and att'ord stops which positlifelywlimit the extentot -the insertion of the: reduced ends of the transom into the n To ali'ord additional stops for the same purpose, the

'transom is shown'ns provided near its upper surface' with laterally proj ect-ing end flanges 6, the extremitieso "which abut against the inner surfacesof tne side frame castings l adjacentt-o the transom seats thereot.A i

"ffterthe ends of tie transom have been Iinsert.edin the seats otftliersideltrame cast-` fings 'andthe flanges thereo interloclied with the said side trames", 1as already stated, thdlspa'ces betweenthe tops of the seats and the' upper surfaces-of the reduced ends of' said transomare.lilled-v by soecalled ltilhng pieces 2, and these'tll'ling pieces.- are-then rigidly secured to the side ramesgr'preferably, by rivets 8 passed? through reduced in- Eteinnedirte portions ofthe inwardly extend .ingtlianges oi said filling 'pieces yand through tical webV portions which overlap portions 'othe adjacent `ends of. the tran tlienpper flanges of llien the filling pie".

seing, as Well are" applied, t1

transom inf positively hcldftlie ends of the the respective seatsl es' Immediately inside of thc truck side frames, the transom is formed with deep open topped spring pockets t) which, as shown, are rectangular' in' horizontal cross section. in each of these spring pockets is a set oi' 'coiled springs 10, as shown, tour in number. .llach set of springs' supports a lower roller bearing plate 1 1 which is guided for vertical movements bythe pocket in which it is inserted. Each lower-roller .bearing plate 11 Supports a set ot' rollers 12- thai extend transversely of the transom and, in turn, each ot` these sets of rollers supports an intermediate roller bearing plate 13. The said rollers 12 engage concave seats in the said plates 11 and 13l and provide for lateral movementv of a. body or car bolster 1-1 transversely of the truck. On each intermediate or Afloating bearing plate 155 is a set of rollers 15 that extend approximately at a right angle to the underlying set of rollers 12, and each of these sets ot' rollers 15 supports an upper roller bearing lplate 1G which is secured to, or connected for movements with, the overlying-I body bolster 14. The rollers 15 provide for the radial. or oscillatory movements of the body bolster 14 in respect to the transom 4 or, in other words, .for radial or oscillatory movements of the truck frame in respect to the car body. These complex roller bearing devices, which providefor both radial and lateral movements of the truck frames, in 'f et to the car- 1body, are, except for the uit nner of thein p "jlication, approximately' the same as those isclosed in my ending application S. Nf-l;5-2,`531, filed of ate December 11, 1909,' 1entitled Car truck, and ll '-.lofthe sameggeneral character as those 'disclosed 'andmore broadly claimed in patent to Lake and Deverall No. 7 98,35() of date .A1.1gust29, V1905.

.'lhefbody-bolster 14 is intermediately p iv- 'ote'd to the-transom 4 by a connection which "permits, in addition to the customary radial io )ivotal movement, both vertical movements of the said body bolster, 1n respect to the transom and other parts of the truck frame-',gand endwise movements of the said bolster transversely of the truck. This novel pivotal'connection is preferably arranged as follows: To the intermediate portion of the body bolster 14 is rigidly secured a depend- .ing hollow hub 17 that depends through a 'longitudinally elongated passage 18 in the upper web of the transom 4. On its upper web. the said transom is provided with a rectangular guide flange 19 that surrounds the elongated passage 18.

'.l` he numeral 2O vindicates a rectangular guide block which is mounted to slide loosely within the ,f ruide flange;l 19 'in a `direction Vtrarisversely ofigfthe truck and is provided with a large perforationvin which the hub 17 is loosely seated withfreedom for both supported by said s ',rings oscillatory and vertical movements. Rigidly secured to the extreme lower end of the hub 17, as shown, bymeans of a short -nutted bolt Q1, is a cross bar or stop 2Q, the ends of which overlap an elongated passage 1S and by atlording a stop which will positively limit the upper movement of the body bol ster under the lifting action of the springs 10. when the car carries a light load or when there may be a tendency of the car body to jump in respect to the truck.

In .this constructlon, as is evident, no weight whatever is carried by the pivotal connection between the body bolster and tra nsoiinlnlt the Weight of the car body and its load is entirely carried by the spring su )porting roller bearing devices.

lThe above described arrangement, as is evident, permits the use of a very low' down truck structure. Furthermore, the said construction is simple, strong and durable.

What I claim'is:

1. In a car truck, the combination with side frames and a transom connecting the same, or" a body bolster' intermediately pivoted to said transom, and roller bearing devices and cooperating springs supporting the said body bolster with freedonifor oscillatory` movements, the said springs being mounted in seats formed in said transen@4 2. In a car truck, the combination wi l side frames and a transom connecting the same, ofa body bolster intermediately pivoted to said transom, and roller bearing devices and coperating springs supporting the tory movements, the said springs being mounted in seats formed in said transom and located entirely inside of the truck side frames. f

3.'In a car truckfthe combination 'with side frames and a transom'connecting the same, said transom having lopen support s ring pockets formed therein -and located inside of, the said side frames, springs in said pockets, a lower roller bearing cplate and gui e for vertical movements y e said pockets, a bod bolster intermediately connected to sai transom with freedom for oscillatory movements and for vertical movements cor- 'resonding to the spring movements, and

rol er bearing devices interposed between said lower bearing plate and the said body bolster, substantially as described.

4. Ina car truck, the combination with side frames and a. transom connecting the same and provided with open topped pockets located inside of the said side frames, springs in saidgpockets,- a bodybolster intermediately pivoted-to said transom with freedom for movements transversely of the truck, upper. lower'and intermediate roller bearing plates. said upper bearing plate being connectlengage the upper web of the transom, thercsaid body bolster with freedom for oscillaf .las

ed to said body bolster and said lower roller bearing plate beingr supported by said springs. and two sets 'ot' rollers, one extended longfitiulinally and the other transversely of said transonn'the lower of said rollers being interposed between said lower and intermediate bearing plates and said upper rollersI being interposed between said intermediate and upper bearing plates, substantially as described.

5. In a car truck, the combination with. side trames and a transom connecting the saine, of a body bolster' intermediately pivoted to said transom with freedom for vertical movements in respect thereto, and springs and spring supported roller bearing devices interposed between said' transom and bod)Y bolster and taking the weight of the load, substantially' as described.l A

o. In a car truck, the combination with side frames and a trans-oni connecting the same. oi a body bolster intermediately pivtod to said transom with freedom for veri-al movements i-n respect to said transom and. for movements"transversely of the truck,

and springs and spring supported rollerv bearing devices interposed between said transom and body bolster and arranged to carr)v the entire load and to permitthe abovev noted movements f said body bolster in respect to said truck, substantially as der scribed.

7. In a car truck, the combination with side frames and a transom connected with the same, of a body bolster intermediately pivoted to said'transom with/'freedom -for t side frames having),` transomed sea-ts, of a transom connecting said side frames, the said transoms having vertically reduced ends constructed for interlocking enga ement with the lower port-ionsof tbe saidg seats., and filling blocks appliedvin the Agapsbetween the upper portions of the said :seats and the reduced ends of the said transoms, and serving to hold said transom interlocking the said side frames', substantially as described.
