CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 592,843, dated November 2, 1897.

Application filed July 19, 1897.

To all whom it may concern:

Be it known that I, BENJAMIN W. TUCKER, 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 Car-Trucks, of which the following is a specification.

The invention relates to improvements in car-trucks, and pertains particularly to the side frames or beams and the pedestals formed at the ends of the side frames to receive the axle-boxes and admit of the latter having a vertical reciprocating movement, as hereinafter described and claimed.

In accordance with this invention the side frames of the truck are duplicates of one another, and each is preferably formed of a continuous rolled beam having upper and lower inwardly-turned edge flanges and an inner flanged section applied to each end of said rolled beam and having its outwardly-turned flanges secured to the inwardly-turned flanges of said beam, whereby a box-like structure is formed at each end of each side frame to receive the car-springs. The pedestal-space is formed at each end of each side frame in said box-like structure and completed by a wrought-metal strap secured to the lower flanges of said beam and inner flanged section.

4The object of my invention is to produce a car-truck frame of great efficiency and durability and capable of withstanding the severe usage to which car-truck frames are subjected.

The invention will be fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which- Figure l is a side elevation, partly broken away and partly in section, of a car-truck frame constructed in accordance with and embodying my invention. Fig. 2 is a like View of one end of the side frame, the spring over the axle-box being omitted. Fig. 3 is an end View of a portion of said truck-frame; and Fig. 4 is a top view, partly broken away and partly in section, of same.

In the drawings, A designates the main side frame or beam, having the upper and lower inwardly-turned flanges, (lettered B C, respectively,) and D the inner end sections, preferl Serial No. 645,125. (No modelo ably of cast metal, having the outwardlyturned upper and lower flanges E F, which, as shown, are secured to the aforesaid flanges B C of the main side beam. The main side beam A has formed in it adjacentA to its ends the recesses G of rectangular outline and forming .a part of the pedestal-spaces for the axle-boxes H. The recesses G are cut upward into the beam A from the lower edge thereof. The upper and lower flanges B C of the side beam A are preferably thicker than the web portion of said side beam.

i The inner end sections D, appliedto the inner sides of the ends of the side beams A, correspond with one another, and the upper flange E of each of said inner sections preferably passes over the upper flange B of the side beam A, while the lower flanges F of said inner sections pass outward over the lower flange C of the said side beam A. The inner end sections D are each formed with the recess I, corresponding with the recess G, formed in the side beam A, but preferably at the upper portion greater in width than said recess G, as indicated by dotted lines in Fig. l and full lines in Fig. 2.` The inner end sections D are each formedwith 'the vertical flanges J and horizontal flanges K, the former of which are at opposite sides of the lower portion of the said recess I and constitute rubbin g-surfaces for the axle-boxes H. The rubbing-ilanges J extend between the lower horizontal flanges F of said end sections D and the upper flanges K, the latter affording increased strength to the rubbing-flanges J, as well as to the inner end sections D. The inner end sections D are preferably each cast in one integral piece, and each comprises the vertical web portion L, the upper outwardlyextending flange E, the lower outwardly-extending flanges F, the rubbing-flanges J, and the horizontal flanges K, the latter being at the upper ends ofthe rubbing-flanges J and coeXtensive in width with the lower flanges F. When the inner cast sections D are in position, the upper flange E thereon will eX- tend outward to the outer vertical face of the side beam A, and the flanges F J K of the contact with the inner vertical face of the web of the side beam A.

As indicated in Fig. 2, the rubbing-flanges said end sections D will extend outward to.

J extend inward toward one another beyond the vertical sides of the space I, formed in the inner iianged section D, and the inner facing sides of the flanges J are on a vertical plane with the sides of the yrecess G, formed in the side beam A, as indicated in Fig. l, and also on a vertical plane with the opposite facing sides of the strap M, as shown in Fig. 2. The strap M will preferably be formed of wrought metal and have its ends bent outward from one another to contact with the lower surface of the flange C of the side beam A. The strap M receives the lower portion of the axle-box II and is secured in position by the bolts N, which, as more clearly illustrated in Fig. 2, extend through the lower flanges F of the inner section D, the lower flange C of the side beam A, and the ends of the strap M. At the outer ends of the Vflange or flanges F at the lower edge of the inner section D are formed the small iianges O, contacting with the heads of the bolts N to prevent said bolts from turning axially under the jarring action of the truck.

The inner end sections D at their lower portions correspond in width with the width of the iianges of the side beam A, but at their upper portions, as indicated in Fig. 3, extend inward, so as to form abundant space between their web L and the web of the side beam A to receive the elliptic spring P, which, as illustrated in Fig. l, is held between the upper surface of the axle-box II and the lower surface of the upper Iiange B of the side frame A. The lower surface of the upper fiange B of the side beam A contains the recess Q to receive the small projection R, carried by the upper band of the spring P, and the upper surface of the axle-box II is formed with the gibs S to receive the lower edges of the lower band of said spring P, and thus the spring P both at its lower band and upper band is securely held against displacement and directly over the axle-box II. The inward projection of the upper portion of the web L of the inner section D to receive the spring P necessitates a greater width in the recess I than the recess G of said beam A, in order that the flanges on the axle-box II during their upward movement will above the flanges .I have free play, as illustrated in Fig. 2. If the spring P were narrower, the web of the inner section D would not require to be projected along its upper portion, and under such condition the recess I would correspond in width with the recess G. It is desirable, however, to employ a spring P of requisite dimensions, and hence the upper portion of the inner section D should ordinarily be projected inward, as indicated in Fig. 3, so as to form abundant space for said spring. The upper flange E of the inner section D is secured to the upper fiange B of the side beam or frame A by means of the rivets T, and the lower flanges F of said inner section are secured to the lower iiange C of the side beam or frame A by means of the bolts N, which, in addition to connecting the inner section D and the side beam or frame A, also secure the pedestal-strap M in place.

The axle-box II is held within the pedestalspace formed by the beam A, inner section D, and strap M, and is adapted to have a vertical `reciprocation within said space.

By means of the present invention I ani enabled to produce a very strong truck at comparatively small expense and with the minimum amount of hand labor. The side beam A is in a continuous piece of rolled beam cut olf square at its ends and having the recesses G formed therein adjacent to said ends. The inner end sections D are, as above indicated, preferably cast in one integral piece to fit the inner sides of the ends of the side beam A, and said inner sections D, while furnishing the rubbing-surfaces for the axleboxes, form box-like structures at the ends of each side frame to receive and protect the springs P and serve to connect the upper and lower flanges B C of the side frame A, thereby strengthening the truck-frame and completing a structure capable of withstanding the severe usage to which car-truck frames are ordinarily subjected.

The strap ill is shown in its best form and as an integral piece of wrought metal bent to the required shape to inclose the opposite sides and lower end of the axle-box, said strap thus constituting the lower portion of the pedestal-frame. The invention is not limited, however, to the special strap M shown, since said strap may be made in several connected pieces, if preferred, instead of one piece, in a manner well known in this art. The term strap, therefore, is not to be taken as a word of special limitation.
