CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 714,674, dated December 2, 1902.

i Application filed August 21,1902. Serial No. 120,475. (No model.)

To all whom, t 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 usefullmprovements in Car-Trucks, of which the following is a specification.

The invention relates to improvements in car-trucks; and it consists in the novel features and combinations of parts hereinafter described, and particularly pointed out in the claims.

The object of the invention is to simplify and render more durable and efficient cartruck frames, and the said invention pertains more particularly to the side and pedestal frames of the truck.

In carrying out my invention I construct in the preferred embodiment the side frames of the truck from rolled channel-beams cut o at suitable lengths and equipped with pedestal-frames `for the axle-boxes, while the transoms are also made from rolled channelbeams and havetheir iianges extended outwardly toward the ends of the truck, the ends of said transoms being brought into contact with the inner sides of the side frames and secured by means of suitable plates. The side frames of the truck have their flanges extended outwardly, and intermediate the upper ends of the axle-boxes and the lower surface of the upper flange of the side frames are provided elliptic springsV bearing against said axleboxes. ed in accordance with my invention is one of great durability and efficiency and capable of being manufactured without undue expense.

Theinvention 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, partly broken away at one end, of a car-truck constructed in accordance with' and embodying the invention. Fig. 2 is a top view of a portion of same. Fig. 3 is an enlarged side elevation,

" partly broken away, of one end of the side frame of the truck. Fig. 4t is a vertical transverse section through a portion of the truck on the dotted linedl 4. of Fig. 3; and Fig. 5 is an enlarged top view, partly broken away and partly in section, of a part of one end of The truck-frame construct,-A

one of the transom-beams and a portion of a side frame and is presented to illustrate the method of securing the end of the transombeam to the side frame.

In the drawings I illustrate as much of an electric or passenger car truck as is suicient to clearly disclose my invention, the opposite sides of the truck-frame being duplicates of each other and one side frame being fully illustrated.

In the drawings, 10 designates the beam side frames; 11, the truckwheels; 12, the customary journal-boxes for the car-axles, (not shown;) 13, the elliptic springs bearing upon the upper ends of said journal-boxes and confined at their upper portion below the upper outwardly-projecting iiange 14 of the side frame, and 15 the parallel transom-beams rigidlyconnecting the side frames of the truck. The side frames 10 are connected together at their middle portions by means of the transom-beams 15 and at each end by a suitable bar 16, the bar 16 being of any suitable form or construction and not being specifically claimed herein.

The side frames of the truck are each constructed from a rolled channel-beam having the vertical web portion 17 the aforesaid outwardly-projecting flange 14. along the upper edge of said web portion, and the corresponding lower flange 18, said lianges 14 and 18 both projecting outwardly from the web portion 17 and leaving the inner face of the side frames 10 smooth and regular. frames 10 are each formed from a rolled channel-beam cut out at its opposite ends to form the spaces 19 for the journal-boxes 12, said spaces 19 being cut through the lower iiange 18 and through a portion of the web 17, but

not through the upper flange 1li, the flange 14 and a part of the web 17 over the spaces 19 being left intact. The journal-boxes12 are partly below the lower iiange 18 of the side frames, and the lower portions of said journal-boxes are inclosed on their three sides by the pedestal-frames 20, having the horizontal arms 21, iitting against the lower surface of the flange 18 and rigidly though detachably secured thereto by means of the bolts 22, which extend through said arms 21 and said flange 18 and also through the auxiliary pedestal-frame members 23, which are in the nature The side IOO of triangular-shaped castings fitted upon the upper surface of the lower flange 18 at the opposite edges of the spaces 19 and affording vertical flanges 24, facing the journal-boxes 12. The pedestal-frame members 23 in addition to possessing the vertical fianges 24 for the journal-boxes 12 have the flanges 25, fitfing against and riveted to the web 17 of the side frame, and the lower horizontal fianges 26, seated upon the lower iange 18 of the side frame and secured thereto by means of the aforesaid bolts 22. The pedestal-frames 20 correspond in width with the width of the lower edges of the side frame, and the guiding-surfaces afforded by them are continued upwardly by means of the flanges 24 of the auxiliary pedestal-frame lnembers 23.

,The journal-boxes 12 have upon their upper ends suitable sockets or frames 27 to receive and confine the middle portion of the lower section of the elliptic springs 13, the upper sections of which are held in suitable frames 28, riveted fo the lower surface of the upper fiange 14 of the side frame, and, as may be observed on reference toFig. 4, the springs 13 and parts connected therewith, while fully exposed to View, are substantially concealed below the upper flange 14 of the side frame.

Upon the inner ends of the side frames 10- and in line with the elliptic springs 13 are rigidly secured the frames 30, which define an inverted-U-shaped outline and are of angleiron form in cross-section, these frames 30 being riveted to the inner face of the webs of the side frames 10 and strengthening that portion of said side frames about the space 19 for. the axle-boxes and above the linev of the car-axles. i

The side frames 10, as has been explained above, are each made from a rolled channelbeam, and the upper and lower fianges of each side frame extend outwardly. At each end of each side frame the channel-beam is preferably cut out or recessed, as at 3l, to adord adequate space for the parts to be carried by the truck-frames and for coupling cars together, the formation of the recesses 31 resulting in an extension 32 being formed, and it is to the extensions 32 at ythe ends of the side frames that the end bars 16 are secured, as shown in Figs. 1 and 2. The bars 16 are each in one continuous piece, having their ends bent inwardly and extended along the web of the extensions 32 of the side frames, to which the ends of the said bars 16 are riveted. The web portion 17 of the side frames may be cut out, as at 33, to allow for the projecting ends of the bolster and its springs (not shown) and, as at 34, for permitting the inspection of the interior parts of the truck and the convenient manipulation or application of said interior parts. I regard it as important that the side frames are each made from a rolled channelbeam and that the flanges of the beam extend outwardly, and it is also an important feature that the spaces 19 are so disposed that a portion of the web and a portion of the lower fiange of the side frames are at opposite sides of each of said spaces, said spaces being set inwardly -from the ends of the side frames. It is obvious that the side frames made from commercial rolledchannel-beams may be produced at small expense, while at the same time said side frames constructed as described possess great durability and are capable of withstanding the rough usage to which car-truck frames are ordinarily subjected.

The transoms 15 are of rolled channelbeams corresponding with the channel-beams from which the side frames 10 are made, and the ends of the transom-beams 15 abut against the inner faces of the side frames 10, the ends of said transom-beams beingsecured to the side frames by means lof the corresponding upper and lower plates 35 36 and angle-iron plates 37, the latter being vertically disposed between the upper and lower flanges of the transom-beams and being riveted to the web portion of the transom-beams and si de frames, as more clearly illustrated in Figs. 4 and.5. The upper and lower plates 35 36 are each in one integral piece, and said plates are riveted to the flanges of the side frames and the anges of the transom-beams. The plates 35, 36, and 37 not only serve to connect the v ythe said springs being supported by means of suitable saddles 38, suspended from the transom-beams and affording in their upper portions suitable rubbing-surfaces for the bolster.

yThe car-truck frame as a whole has been constructed with the view of attaining great strength, durability, and efficiency at comparatively small expense and at the saine time to provide a car-truck frame-in which elliptic springs may be employed overthe journal- IOO IIO

boxes in an exposed position, but at the same time substantially concealed below the upper fiange 14 of the side frames. The construction and arrangement of the pedestal-frame members are also desirable features and constitute a portion of my invention.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a ear-truck, the channel-beam side frames 10` having their upper and lower flanges 14, 18, extending outwardly from the web portions, said beams at their ends being cut away to form the spaces 19 forl the axleboxes, and said iianges 14 above said spaces being left intact, combined with the axleboxes, thepedestal-frame members secured to the lower Han ges of said side frames and inclosing the lower ends of said boxes, the auxiliary pedestal-frame members 23 secured to said side frames at oppositesides of said spaces, the springs confined at the outer side of said side frames intermediate the upper ends of said boxes and the lower surface ofthe upper flanges 14 of the side frames, and sockets for retaining said springs in position; substantially as set forth.
