FREIGHT-CAR AND LOCOMOTIVE-TNDER TRUCK.

Specification of Letters Patent.

Patented Aug. 1l, 1908.

Application led October 23, 1903. Serial No. 178,216.

To all whom it may concern:

Be it known that we, RANsoM O. WRIGHT and FRANK E. STEBBINS, citizens of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, and Vashington, District of Columbia, respectively, have invented certain new and useful Improvements in Freight-Car and Locomotive-Tender Trucks, of which the following is a specification.

The object of our invention is the production of a car truck which shall especiallybe adapted for use under freight cars and locomotive tenders; which shall be comparatively cheap in first cost and very strong and durable; which shall be flexible and equalize the weight upon the pairs of wheels so they may follow and adapt themselves to the inequalities of the track and the car body ride easily; which shall be of such construction that it may be manufactured in the ordinary car shop, and repaired when necessary7 without the use of special tools or appliances; which shall be so fashioned that part of the frame may easily be raised and with it the end of the car body so as to bring the coupler to the proper height from the top of the rail; and which shall possess other desirable features and characteristics constituting the same a superior means for performing the requisite functions.

NVith the above main ends in view our invention consists in a truck having a transsom or transoms located between the pairs of wheels, side pieces secured to the ends of the transom or transoms, equalizers resting upon the journal boxes, and spring hangers and springs in connection with the equalizers the said side pieces being supported by the springs, and the ends of the side pieces with their bearings loosely engaging the journal boxes.

It further consists in a truck having equalizers, a frame, and springs located beneath the side pieces of the frame and supported by hangers which depend from the equalizers.

Finally it consists in certain novelties of construction and combinations and arrangements of parts as hereinafter set forth.

The accompanying drawings illustrate one example only of the physical embodimentof the invention, and a modification of the transoms, constructed according to the best of the several modes We have so far devised for the practical application of the principle.

Figure l is a side view in elevation of the truck. Fig. 2 is a quarter top plan view, and a quarter sectional view taken in a horizontal plane on the line xpm of Fig. l. Fig. 3 is a half end view in elevation. Fig. 4 is a perpendicular section taken on line y-y. Fig. 5 illustrates one of the pedestal pieces removed from the frame. Fig. 6 shows in section at the center a modification of the disposition of the transombeams, the flanges thereof being turned outwardly.l

Referring to the several figures, the numeral l designates the transoms, in this instance comprised of channel beams with their flanges facing each other; 2, 'Hanged connecting or spacing pieces of channel iron shape located between the transoms adjacent to the webs of the transoms; 3 and 4 are top and bottom tie plates riveted to the flanges flanges of the transoms; 13, rivets uniting the top gusset plates to the top flanges of the side pieces; 14, recesses formed adjacent the ends of the side pieces by cutting away a part of the web and bottom flange of a side piece snear each end; l5, the pedestals 75 for guiding the journal boxes and reinforcing the ends of the side pieces, each pedestal being of a l-l shape as shown; 16, the web of each pedestal; 17, the bearing flanges of a pedestal', at right angles to the web, and which fit within recesses formed in the perpendicular sides of a journal box; 18, stiffening ribs extending between the web and bearing 'fianges; 19, a thimble or spacing piece; 20, a threaded bolt passed through the holes at the ends of the pedestal jaws and also through the thimble or spacing iece; 2l, a nut on the bolt by which the thimble or spacing piece is clamped between the jaws, and the jaws themselves rigidly united; 22, rivets passed their centers and having their flanges riveted of the transoms; 5, the side pieces, in this inthe top stiffening ribs of a both pedestal jaws are secured to the flange of the side piece; 23, rivets passed through the web of the pedestal and the web of a side piece 24, the journal boxes; 25, recesses in the sides thereof within which are located the pedestal bearing or guide flanges; 26, a seat in the top surface of a box to confine the end of an equalizer against sidewise movement; 27, the equalizers, one only of which is shown; 28, the rounded bearing surface at each end of an equalizer where it rests upon the top of a journal box; 29, perpendicular surfaces of the equalizer located adjacent the bearing flanges of the pedestals and which prevent the excessive longitudinal movement Y of the equalizer; 30, the thickened portions of the' equalizer for strengthening the same and forming large bearing areas for the spring hangers; 3l, seats for the spring hangers at the top edge of the equalizer; 32, slots made in the web of a side piece and substantially at the neutral axis whereby the side piece is not materially weakened; 33, spring hangers each in this instance made by bending a rod to a n shape, one arm thereof being passed through a slot 32, the curved portion resting in a seat 31, and the free ends depending and extending below the side piece; 34, the threaded ends of a hanger; 35, two coiled or helical springs; 36 top spring caps; 37, a seat formed in the top'surface of a cap within which rests and is conilned the lower flange of a side piece g 38, the bottom spring seats 39 perforated ears or lugs upon the sides of the bottom spring seats and through which perforations the threaded ends of a hanger are passed; 40, nuts upon the threaded ends of the spring hangers; 41, the wheels 42, the axles; and 43 are the journals of the axles located within the boxes.

Fig.k 6 illustrates in section a modified disposition of the transoms, the flanges being turned outwardly to facilitate the application of the rivets which pass through the flanges where the top and bottom tie and gusset plates are located.

The drawings show the several parts of the truck in the relative positions which they occulpy when the truck is supporting the end of a oaded car, the springs being under compression and there being also open spaces 44 each'of approximately 2 in depth between the top of a journal box and a horizontal line bounding the bottom of the recess 14 in the end of a side piece.

The weight of the car body and its load is first taken by the transoms, then by the side pieces and the springs which are not compressed sufliciently to allow the ends of the side pieces to come into contact with the tops mitted by the s ring hangers and equalizers to the journal boxes, journals, wheels and track.

of the journal boxes, and thereafter transped-estal whereby distance apart the side It will be observed that the combination and arrangement of parts produces a very flexible truck having the movable parts where they can easily be inspected and replaced or repaired when necessary. As the springs are spaced but a comparatively short pieces may be very light in weight and their strength at the ends be sufficient only to hold the journal boxes in place and to take the strains in bulling and in the application of the brakes.

From the foregoing description it becomes obvious that'we have produced a truck which fuli'ils all the conditions set forth as the end and purpose of our invention. We have shown the transoins as com rised `of two channel beams of rolled steel) but a single transom may be substituted therefor; the sides also are of rolled channel beams 13 deep and having flanges 4 wide`suitable for use with trucks having 33 wheels-but other shapes in cross section, such as I L l '.l 'L I beams or plates, or those of composite structure, rolled, pressed, or cast to shape, may be used. The channel beam with the flanges turned outwardly is a preferable construction as it allows the side to be located relatively near the wheels giving the requisite space for the equalizers to be centered over the journal boxes and the journals. The pedestals we have shown made of cast iron, malleable iron or steel and each with the weblocated upon the rear surface of the end of a side piece, and with the bearing flanges extending outwardly beyond the web of the side piece, but other constructions may be adopted especially when side pieces of a different shape in cross section are employed. The equal-izers are preferably of cast steel and of the general shape shown however, they may be forged or comprised of a plurality of pieces united in any suitable manner. The hangers represent the best form we have so far devised and are of a desirable construction, inasmuch as in service they can move within limits and not strike other parts of the truck, and, moreover, by screwing up the nuts upon the hangers the truck frame and car body can be raised as hereinbefore set forth. The arrangement of the springs may, of course, be modified. They may be located nearer the transoms, and a single composite spring, a nest of four coiled springs, or two parallel springs arranged at right angles to the position of those shown be adopted as the service may demand. The arrangement illustrated is satisfactory as the springs are directly below and in line with the side frame and the lower flange of the latter is seated within the upper surface of the spring cap.

While we have'specilically set forth in detail only one example of the physical embodiment of our invention we do not thereby intend to limit its scope to such example, in-

asmuch as the principle may be embodied in other forms and shapes and by other modes Y which will not constitute substantial departures.
