To all 'whom it 'may concern:

Be it known that I, JOHN C. BARBER, a cit-izen of the United States, residing at Chica o, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Trucks; and I do hereby'declare the followin to be a full, clear, and exact description o 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 car trucks of the general design disclosed in my prior patent 863,012 of August body andits load are carried directl from the side frames of the truck throug antifriction devices aifording provision for a limited lateral motion of the car body relative to the truck, in addition to the custom motion of said parts. The structure an mounting of the anti-friction devices, and the swiveling connections between the vtruck and the car body are substantially identicalV with those disclosed in my said prior patent.

My present invention has for its object to provide certain improvements in the side frames and the bolsters, with a view of securing greater convenience and eiiiciency in the coperation of the said parts.

T o 4these ends, my invention consists of the novel devices and combinations of devices hereinafter described and defined in the claim.

The invention is illustrated in the accomwherein like references throughout the several ary swivelin panying drawings, refer to like parts views.

In said drawings; Figure 1 is a view of m improved truck, chlefly in end eleva'- tion, but with some parts shown in diagram lines only, and other parts broken away, and others removed. Fig. 2 is a plan view of a part of the truck, with some portions removed. Fi 3 is a view partly 1n elevation and artly 1n vertical section on the line w3 :o3 o Fig. 1. Fi 4 is a view showing the bolster in plan, dget-ached, with a portion of the same broken away; and Fig. 5 is a view showing the main part of one of the side frames, detached, in end elevation in respect to the trucks, with a portion broken away, and showing lin dotted lines the position which the bolster takes in being inserted o 5 removed from the bolster spaces.

i The tie baril and the :lower arch bar 13, 1907, wherein the careach side frame are substantially of the customary form. The top arch bar 3, the bolster columns 4, and the column base plate 5 are all formed inte ral with each other preferably of cast stee but may be made of pressed steel if so desired.- vThe column base 'plate 5 is of saddle form in cross section so as to embrace the underlying portionsl of the tie bar 1 and the lower arch bar-2, and permit all the arts to be rigidly connected together by t 4ig. 1. The central portion of the top arch bar 3 is laterally expanded and provided with a' central opening 7 of the proper size to permit the side bearings to work'therethrough, as will later more fully appear.

e bolts 6, as clearly shown m l Angle ironcross ties 8 are seated on thev column ybase plates and rigidly secured to the base platesl and to the column flanges, and serve to ri idly connect together the two side frames o the truck. On the horizontal flanges of the cross ties 8 rest suitable spring base plates 9 supporting the springs 10, suitably spaced in respect to each other. lThe bolster 11 is, as shown, composed of an ordinary steel I-bar, laid down latwise, with the end portions of its horizontal web resting directly on thg ysprings 10. The portions of the webs which so rest on the springs are thickened up and provided with suitable centering 1u s 10a for the .sprin s, as shown in Fig. 3 an in dotted lines in ig. 4. The space between the columns 4 is a little larger than the width of the bolster 11, and the bolster is provided with guide lugs, one set of which is marked with the numeral 12 and bo ster columns 4 when the parts are inV working position, as shown in Fig.

1, and cooperate with said columns to guide the bolster in its up and down motion while preventing any lateral motion thereof. At least one set of the bolster uide lugs are removably secured to the bo ster. As shown, this is the set marked with the numeral 12. Hence, when the lugs the bod of the bolster 11, the bolster can be inserte in or removed-from the spaces be tween the columns 4, with an endwise action, when the bolster is madey to'take a position between diagonally opposite corners of the bolster spaces, as shown in then be turned'down into its working position with the fixed set of guide lugs 12" em- Fig. 5. It can 12 are removed from the other or removable set of guide lugs 12 can be applied and bolted fast in working position. After the bolster is thus put into position, the spring base plates 9 and springs 10 can be inserted by lifting up the bolster. Hence, these features of construction constitute a material improvement for convenience is assembling the Working parts.

On the bolster 11, directly over thesprings 10, are located roller'bearing plates 13 which may be either cast solid with the bolster, or rigidly'rsecured thereto in any suitable way. 0n the plates 13 are cylindrical rollers 14 extending crosswise of the bolster, and on the rollers 14 rest bearing plates 15; which said parts 13, 14 and 15 constitute the lateral mot-ion anti-friction bearing devices. The

plates 15 have on their faces rollers 16 arranged crosswise of the rollers 14 and secured to depending lugs 18 fixed to 'the radial tothe swiveling center of the truck. On the rollers 16 rest plates 17 removably car'body bolster 19. rIhe parts 16, 17 and 18 constitute anti-friction side bearings supported from the cap plates 15 of the l-ateral motion bearing devices, with the depending lugs 18 from the body bolster 19 Working through the top openings' 7 of the top arch bars 3, these openings being long enough to permit the necessary travel of the side bearings under the radial or swiveling motion of the car body and the truck relative to each other. v

The truck bolster 11 is provided with a lower member 2Oy of a suitable pair of center plates, the other member of which is not shown, but would be connected to the body bolster 19 in the customary way. rThese center plates may be constructed' and fitted together with bufer blocks located between the telescoping parts of the two plates, so as to make the same coperate to take the for- Ward and backward thrusts' regardless 'of the position which the car b ody may occupy relative Ito the bolster of the truck under 4the lateral motion permitted by the anti-friction devices; and to this end, the center vplate member fixed to the truck bolster 11 has an elongated slot 21 to permitthe lateral travel of the king pin connecting the truck and the car bodyall as fully illustrated and described in ymy said prior patent 863,012.

The numerals 22 in Fig. 2, represent brake hanger bearing stud shafts, and the numeral 23 represents a bracket fixed to one of the cross ties or transoms 8 for supporting the pivoted brake lever, not'shown.

In a car truck,.the combination with side frames having bolster columns, of a bolster body in thevform, of an I-beam of less width than the space between said columns and provided with independent guide lugs, the guide lugs on one side of the bolster being permanently riveted to the flanges thereof, and the guide lugs on the other side of said bolster being detachably secured thereto by rigid bolts passed 'through the flanges thereof and through the said detachable guide lugs, and said side frames having openings from which the bolster may be removed endwise when said removable guide lugs are detached and said bolster is turned laterally to an oblique position, substantially as described.
