CAR-TRUCK FRAME.

SPECIFICATION forming part of Letters Patent No. 574,983, dated January 12, 1897. y Application filed July 13, 1896. Serial No. 598,934. (No model.)

To all whom it may concern.-

Be it known that I, EDWARD OLIFF, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Oar-Truck Frames, of which the following isa specification.

The invention relates to improvements in car-trucks, and particularly to the construction of the frames of car-trucks, Without regard to the form or construction of the wheels, axles, axle-boxes, springs, side bearings, or center bearing.

The invention consists in the novel features of construction hereinafter described and claimed pertaining to the side frames of the truck, the pedestals for the axle-boxes at the ends of said side frames, the hinged or removable sections at the outer side and bottom of said pedestals, and the bolster or holsters connecting said side frames.

The object of my invention is to provide a truck-frame of great durability and efficiency, and simple and convenient in constructie and use.

The invention will be fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of a car-truck fra-me constructed in accordance with and embodying the invention. Fig. 2 is a top View of a portion of same. Fig. 3 is an enlarged vertical section of same on the dotted line 3 3 of Fig. 1, looking in the direction of the arrow. Fig. et is an enlarged top View of the step which is secured to the side frame and upon which the lower iian ges of the rolled beam bolster or bolsters are secured. Fig. is an end view of a portion of the truck'. Fig. (iis a detached enlarged top View of the two castings which form a portion of the pedestalframes and the receptacle for the usual springs to be located above the axle-boxes. Fig. 7 is a detached side elevation of one of said castings. Fig. 8 is an enlarged detached side ele'- vation of the hinged and removable portion of the pedestal-frame. Fig. 9 is an enlarged end view of the pedestal-frame castings. Fig. lOis a top View of the bracket forming a part of the pedestal-frame and to which the hinged and removable portion thereof is connected.

Fig. 11 is a side elevation of same. Fig. 12 is a detached side elevation of one end of the side frame of the truck, less the pedestal connections which in Fig. 1 are shown applied thereto 5 and Fig. 13 is an enlarged top view, partly in section, of a portion of a side frame and adjoining end of bolster, showing the means for securing one to the other, the top securing-plate and the top flange of the side frame being removed.

In the accompanying drawings, A designates the side frame of the truck, which frame is formed of an I-beam having at its upper edge the tlangeB and at its lower edge the flange C, said anges being parallel with one another and on straight lines.

The side frame or beam of the truck is formed at its ends with the spaces D (shown more clearly in Fig. 12) for the reception of the axle-boxes and their springs. The spaces D are cut upward into the ends of the I-beam A, but do not entirely reach the upper flange B of said beam, whereby a portion (lettered E) of the web of the beam A is left below the upper flange B and above the space D. At the outer side of each space D the. lower part of the beam Ais entirely cut away, as shown in Fig. 12, while the upper portion thereof formsl a depending flange F, which bounds the upper outer side of said space D, and to which portions of the pedestal-frames are secured, as hereinafter described.

The side frames A correspond with one another at opposite sides of the truck, and the ends of the side frames correspond with one another at each side of the truck. Upon opposite sides of each end of each side frame A of the truck, and surrounding the inner and upper sides of the spaces D, are secured the pedestal-frames G G, which correspond and are secured in alinement with one another at opposite sides of the beam A. The pedestalframes G are each formed with the liange H, fitting against and riveted to the web of the beam A; the flange Lwhich aifords a rubbingsurface for the axle-boxes; the half-section of the spring-receptacle J, which extends entirely across the upper end of the space D; the flange K, which fits against and is riveted to the adjoining iiange F' ofthe beam A, and the horizontal flanges L, which it against the lower surface of the upper flange B of IOO the beam A and are riveted thereto. \Vhen the castings G G are placed in line with one another upon opposite sides of the beam A, one set of rivets passing through the same and the said beam will secure both of the castings in position, and when in position the sections J of said castings constitute a complete inverted reeeptacle for the usual springs located above the axle-boxes. rlhe flanges II I extend downward to the upper surface of the lower flange C of the I-beam A, and the receptacle-sections J extend entirely across the spaces D from the vertical flange I to the longitudinal flanges K, and said receptaclesections when secured impinge between their upper facing edges that portion E of the beam A left below the upper flange B and above the space D. The castings G are further secured by means of rivets passing downward through the flange l5 and the upper ends of said receptacle-sections J as shown in Figs. l and i. The flanges L of the castings G are at each end of the receptacleseetions J, `as shown, and said castings when constructed and secured in the manner shown anddescribed afford strength and are entirely effectual and durable. The vertical flanges I of the castings (l G, being in alinement with one another and at opposite sides of the web of the beam A, form effectual rubbing-surfaces for one side ot' the usual axle-boxes, and said flanges I terminate directly at the 'upper side of the lower flange C of said beam A. Below the flange C of the beam A at each end of the truck-frame is secured the bracket M, which at opposite sides of its central web N is formed with the horizontal flanges O, which afford means whereby the rivets shown may secure said bracket to the lower flange C of the beam A. The bracket M is also provided with the vertical flange P, which is in direct alinement with the flanges I of the castings (l, and said flange P forms a continuation of the rubbingsurfaee for the usual aXle-boXes. The receptacle-sections J close the upper end of the space D, the flanges I and flange l) form the inner side of the pedestal, and the outer side and lower side of each pedestal is formed by the frame Q, which is bif'urcated at its upper end to pass upward upon the flange F of the I-beam A, where it is secured by means of the bolts R S, the latter being in the upper outer end of the upper portion of said frame Q and serving as a hinge upon which at the proper time said fram e Q may be swung outward and upward from the spaces D. The bolt Ris within the inner thicker portion ol' the upper end of the frame Q andserves to rigidly hold the said frame in its closed or lower position. (Illustrated in Fig. l.)

The frame Q is composed of the vertical arm T and the horizontal arm V, said arms being integral with one another and the end of the arm V being bifurcated and adapted to be secured upon the lower end of the bracket M by means of the bolt \V. It will be observed upon reference to Fig. l that when the fra-me Q is in its closed position it will be securely held by the bolts R, S, and XV, and that upon the bolt S being loosened and the bolts R W withdrawn the side frame Q may be swung outward and upward upon the bolt S in order to free the axle-boxes. The bolt R forms a great security against any accident which might happen it it were omitted and the bolt XV or bolt S should become broken.

lVith the bolts R S lV arranged and operating in the manner shown the outer and lower side of the pedestalspaces become securely closed and the structure is rendered safe and efficient. The inner edges of' the arms T V of the frame Q are formed with the flanges X Y for the axle-boxes- The flange X corresponds with the flanges I I, and affords a proper rubbing-surface for the aXle boxes.

The width of the lower flange C of the I- beam A should beeoextensive with the `width of the flange I on the bracket M and the flanges I of the castings G, and hence, as illustrated, the'end of the flange C adjacent to the spaces D and at opposite sides of the beam A is cut away, as indicated at a, in order that that portion of the flange C between the flanges I P may conform to and form a part of the rubbingsurface for the axle-boxes.

The frames A at opposite sides of' the truck are duplicates of one another, and hence but one of said frames is illustrated in the drawings. Upon the upper flange B of each of said frames is secured the central plate l), which extends inward, as illustrated in Fig. The side frames A are connected by the bolsters c d, which are formed of I-beams connected together at theircenter by the upper plate e and corresponding lower platef,thc upper plate e affording a suitable support for the usual central bearing and being provided with the aperture g for the usual king-bolt.

The upper flanges of the I-beams c d are se.

curely riveted to the plates l) and abut against the inner edges of the flanges B at the upper edges of the side frames A, as shown, while the webs of said I-beams c d impinge the webs of the side beams A and are thereto secured by means of the angle-plates 71.1', which are securely riveted to the said I-beams c d and to the webs ot' the side frames A. The lower flanges of the Isbeams c d extend inward to the webs of the side frames A and are riveted upon the step j, which is riveted to the'side frames and has the inwardly-extending horizontalseats or flanges 7s 7.1, upon which the lower flanges of the I-beams c (l are riveted. The I-beams c (l could, if desired, be of sufficient width to extend entirely down to the lower flanges C of the side frames A, and hence the seats j could be dispensed with. Sufficient strength is, however, se-

cured when the I-beams c d are of the depth indicated, and hence to carry them entirely downto the lower flan ges C of the side frames IOO IIO

and only to the minimum amount of labor in converting them into the side frames A. The I-beams c d are also the usual commercial I- beams, and they also are formed and secu red in place with the least possible amount of cutting and manual labor. The brackets M are cast, the pedestal-frames G are cast, and the removable and hinged frames T are cast. The truck is composed of as few parts as seem necessary, and these parts in their production involve the minimum amount of labor, and when the parts of the truck are secured together in the manner shown and described a truck of great superiority is produced with simplicity of construction and the minimum amount of labor and expense. The truck also possesses the advantages of proper weight, great durability, and entire convenience in use.

To the outer sides of the I-beams c d, in near relation to the inner end of the central plates l), will be provided the supports m m, of suitable construction, for the usual links which support the inside-hun g brakes. (Not shown).

The invention is not limited to the frames Q being technically detachable from the side frames, but they will be removable from the spaces D. rlhe bolts S, securing said frames Q, could be headed or locked to prevent the frames Q from being wholly detached, but would still act as hinges for removing the frames Q outward from the spaces D.
