Application filed October 10, 1907. Serial No. 396,303.

To all whom it may concerm.

-of illinois, have invented certain new and useiul Improvements in Car-Trucks; and l do hereby declare the following to be a full, clear, and exact description of the involition, such as will enable others skilled in the art to which 'it appertains to malte and use the saine. i

My invention relates to car trucks of the type disclosed in my Aprior patent 863,012, of date August 13, 1907, and has 'for its object to improve the construction with a View oi' greater economy in first cpst and greater convenience in the assembling, removal and replacement of parts.' v

To this end, my invention consists ofthe novel devices andcoinbinations of devices hereinafter describedV and defined in the claims. p

The invention is illustratedin the accompanying drawings, vwherein like notations refer to like parts throughoutA the several views.`

' In said drawings; Figure l is a side ele- A vation of my improved truck, with some parts removed, some parts in section, and the position of-some parts shown in diagram 'only'. Fig. 2 is a view of lthe truck chiefiy in cross section, onthe center line of the truck bolster, but with 'some parts shown 'in elevation, and others broken away. Fig. 3 is ahorizontal section, on the line w3 w3 of Figs. l and 2. Fig. 4 is a plan View of one of the side trames and a portion ofthe truck bolster, with some parts broken away, and

others shown inl section. Fig. 5 is a detail, in plan view, showing one end of the truck bolster and the parts immediately connected therewith. Fig. 6 isadetail in cross section, on the line ai of Fig. 5. Fig. 7 is a detail showing .the combined sprin'g'cap and chaiing block bolster end castingfdetached, in plan view; and Fig. 8 is across section thereof, on the line es :v5 of Fig. 7..

The numeral 1 represents the bot-tom tie, the numeral '2 the bottom arch bar, the numerals 3 and 3", taken collectively, represent the `top arch bar, and the numeral 4 the bolster column casting; which parts, when lproperly connected together, onstitute one ot the lside frames of thetruck.

" The side frames are supported from the gournal boxes (not shown) 1n the customary C. BARBER, a-

their vertical way. The positions of the wheels are indicated by the diagram lines 5. The top arch bar of each side frame is composed of an outer angle bar 3 and an inner angle bar 3" set with their horizontal webs uppermost and facing each other; The end portions of the said angle bars are broughtclose together so as to abut or nearly so, and are riveted or otherwise rigidly secured to the underlying end portions ot' the bottom arch bar 2, as best shown in Figs. l and 4. The central portions of the said angle bars 3a and 3b are bent apart from each other and are riveted or otherwise rigidly secured to the bolster coluinn castings 4, as best shown in Figs. 1 and 4, in proper positions to afford clearance between the said parts for the passage therethrough and the proper worlring therein of certain members of the anti- `:trlction bearing devices, as will later more fully a pear.

The olster column castings 4 are provided with pairs of properly spaced guide flanges 4a which project toward the center of the bolster space and are of less height than the bolster castings, as best shown in Fig. 1.

The opposite side frames are rigidly connected together by bottom cross ties G of angle form, set with their horizontal flanges facing cach other and having their opposite ends riveted or otherwise rigidly secured to the opposite pairs of bolster column castings 4. Onthe end portions of the cross ties '6 are located spring base plates shown as composed of a air of angle plates set with anges abutting, or back to erosion.

back, and extendingV on a median line of the v underlying arch and tie bars. Therivedts connecting these plates 7 with the cross ties 6 serve to center the bolster supporting `springs 8 which rest on saidplates.

- The truck bolster is made up of a main or body portion 9, ot' less width than the bolster space between the bolster column castings 4 and a removable end casting 10, of the proper constructionto embrace the ends of the body portion 9 and thereby build the saine out sidewise sufiiciently far to make -the ends of said casting serve as chatting blocks for coperation with the bolster col umns. As shown, the body portion 9 of the bolster is an Lbeam; 'and the said ca-stin 10 is of such construction as to be capable o be-l ing applied and removed endwise to and from the vends of the Lbeain. This casting' 10 is shown detached, with all parts re- `A moved therefrom, in Figs. 7 I and 8, and is shown inwerking position in Figs. 1, 2 and 4. By reference to. these views, it will be .seenthat the casting l0, not only serves to reinforce and build out the ends of the I- beam and to, ail'ord chafing blocks for the y also Abe seen that the casting is rovided vwith' outwardly extended guide ugs l0a which work between' the pairs of vertical guide anges 4*l of the bolster columns 4,

I thus cooperating therewith to guide the bolster in its vertical or spring cushioned movement and to hold the same from any lateral' motion or forward and backward motion. When properly applied to the I-I beam 9, the casting 10 .is rigidly but removably secured thereto by bolts l1, as best shown in Fig. 2. These bolts 11 also secure to the bolster the lower members 12 of the lateral motion bearing plates.

The bolster guide flanges 4, being of less height than the columns 4, as hitherto noted, and the I-beam 9 of less width than the narrowest space between said columns, ythe bolster maybe raised until the 'guide lugs 10a of the castin 10 rise .to a )oint abovethe level oi' the olster guide anges 43;'and, then, by the removal of the bolts 11 the end castings 10 can be removed endwise from the I-beam 9, and, thereafter, the I- beam 9 be Withdrawn endwise through the bolster space. This particular feature of the construction is of great service for 4economy and convenience, in the assembling or removal and replacement of the partsof the truck' bolster and anti-friction bearing devices su ported therefrom, without taking apart4 t e side frames of the truck. RespectingV the said casting 10, it should be-fur-ther noted that its horizontal web underlies the horizontal web of the -beam 9 when the parts vare'in working position. v This makes it feasible to secu're "centerin pockets for the upper ends of the underl mg s rings 8 by simply cutting holes 10b t roug the we of said 8casting 10, as clearly shown in Figs. 7 and Y On the lower members. 12 of the -lateral motion bearin plates are mounted the lateral motion ro 1ers v13;'and on these rollers 13 rest' the plates 14 which, in turn carry .the radial motion or side bearing rollers 1o.

Because of their positions and unctions; the' plates/14 are referred to, in my prior atent 863,012, and in the Lake and Dovere patent 789,350, as oating plates. The radial motion rollers lare disposed. on the-plates '14 crosswise of the lateral motion rollers 13, on lines Vradial to the center of the truck, as best shown in'Fig. 4. `0n saidrollers 15 are mounted the upper members of the side be'arings,which in thisinstance, are' shown as composed o pairs of telescoping parts.

. been modified and improved .poses hereinbefore named.

marked, respectively, V16 and 17, vgg'vtliahe lower parts 16 Iresting on Asaid rolleisltl, and the upper parts 17 v riveted .or otherwise rigidly secured tothebody bolster 18., By reference to Figs. 1 and 2, it will be seen that the so-called floating lates 1 4 "are located below the to arch ars othe side frames, andtravel aterally `with the lateral tion of the body bolster with the underlying floating plates 14' and the lateral motion rollers 13, While, at the same time, permittin the radial motion of the body bolster witli the rollers 15 on the faces of said i plates 14.

The central connections between the truck bolster 9 and the body bolster 18 are precisely the same as in my prior patent 863,012; being such as .to allord, freedom for the swiveling actionwithout taking any part of the load from the car body,`andalso being such as to permit the lateral travel of the body bolsterin respect tol the truck bolster, while preservin a suliiciently close connection to take t e forward and backward thrusts. For this purpose, the bodybolstcr 1&8 has ri 'dly secured thereto, the depending swivel p ate 19 which telescopes with the underlying plate 20 which is ri 'dly secured to the truck bolster 9. The p ate 20 is of rectangular formlin that portion ,thereof wherein the .huboffthe plate 19 travels, and is fitted with segmental builng blocks 2l hugging) the hub of the lower plate. The bu 'n locks l2l'` are of less length than the seator the .same in the lower plate 20, the

clearance beingl suilicient for the lateral travel of the body bolster. The-two plates Maand 20 areconnected by a nutted king bolt: 22 which works in a slot web of the underlying bolster, as shown in Fig. 2.

he bolster column castings 4 are shown asprovided with socket lugs 23 for brake hanger bearings 24 supporting brake-hangers 25, as best shown in Figs. 2 and 4.

Comparing with my prior patent, it will be seen, that the lateral and` radial' motions are the saine., but 'that the side frames and structures for supportin the anti-friction devices providing for t ese motions have 1.
