CONSTRUCTION OF CAR-TRUCKS.

Application filed April 9, 1897, Serial No. 631,473.

To all whom it may concern:

lle it known that we, RANsoM C. lVRiGI-rr and FRANK E. STEBBINS, citizens of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, and at l/Vashington, District ot' Columbia, respectively, have invented certain new and useful Improvements in the Construction of Car-Trucks; and we do declare the following to be a full, clear, and exact description ot the invention, such as will enable others skilled in the art to which it a ppertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part ot' this speci tication.

The object of our invention is the produclion of a car truck which shall have the transoms and sides made of metallic beams preferably flanged and of channel section, and the pedestals of cast metal; which shall be stiff and rigid at the points where the transoms join the sides; and which in one example shall have one leg of each pedestal removable so that a pair of wheels, an axle, and the journal boxes may be rolled out at the end ot' the frame when the weight is taken ott the springs, when springs are used, and without removing the entire frame from the pairs of wheels and axles.

Our invention consists in a car truck having metallic side pieces and transoms with bent or turned ends extended over the journal boxes.

Further, it consists in a car truck having atthe ends inner pedestal legs extending under the ournal boxes, spring pockets, and outer pedestal legs which are removable.

Further, it consists in a car truck having at the ends inner pedestal legs, and outer pedestal legs the upper end of each of which is secured in place by two or more bolts.

Finally, it consists in certain novelties of construction and combinations of parts, especially relating to the pedestals, receptacles above the journal boxes for the springs, and the end portions of the frame, as hereinafter set forth and claimed.

The accompanying drawing illustrates one complete example otI the physical embodiment of our invention relating to the frame, and two moditied examples of the pedestal and end trame constructions, all constructed according to the best modes we have so far Specification of Letters Patent.

devised for the practical application of the principles.

Figure 1 is a side View in elevation of the complete truck. Fig. 9. is a top plan view ot' Fig. l. Fig. 3 is a section on line lll-1V. Fig. 4t an end view oit' the pedestal, Fig. 1, in elevation. Fig. 5 is a section on line UU. Fig. (3 is a view ot a journal box. Figs. T and 8 are side and end views of a modified construction of the pedestal and end oit the frame. Figs. 9 and 10 are side and end views of another inodilication of pedestal and end trame construction.

Referring to the figures of the drawing, and especially to Figs. 1 to (i, the number 95 designates the metallic side pieces of channel shape is cross section, and 96 the transoms extending across the truck frame between the pairs of wheels and thereafter parallel with and to the same distance as the side channel pieces, these transoms being also of channel shape in cross section. The outer pedestal legs are removable, the leg 10S extending downward from the frame and thereafter outwardly and under the axle box 115 and united by bolt 108, to the removable leg 112, said leg 112 extending upwardly and being secured between the side piece 95 and the piece 96 by removable bolts 113; the leg 10S also is secured between and to the side piece 95 and piece 9G by rivets 109, the top horizontally extended part of the same being cut away at its lower central surface above the axle box to form a spring bearing surface within the pocket.

The side channel 95 and the side 90 are pressed outwardly, as shown at 110 and 111, Fig, 3, which is a section on line lV-lV, Fig. 1, to Jr'orm about a half pocket in each, and tlanges 109 are formed to bear under the lower flanges ot' the channel side pieces. At the opposite end of the track, Fig. 1, is a similar lixed leg 102 extending downwardly from the frame below the axle box 1141, secured to swing leg 105 by bolt 11S, having its upper part located between t-he side channel 95 and channel 90 and held in position by rivets 103, tlanges 1011 being provided below the lower flanges of the side trame pieces, and half spring pockets 110, 111 being formed for the reception of a spring and by pressing out the metal of the channel beams. The swing leg 105 is hinged by a bolt 107, and is locked by bolt 10G as well as by bolt 118, the dotted line showing the position of the leg when swung upwardly to allow the removal of the boxes 114.

To facilitate the removal of the axle boxes 114, 115, the springs will, when in use, be held only upon their inner and outer sides by the ribs 115, as shown in Fig. 6. This permits the box to move outwardly under the spring when the spring is released of its load. Transoms 96 are still further secured to side channels 95 by the double headed T pieces, a section of which taken through line U-U, Fig. 1, is shown in Fig. 5, where it will be seen to engage the insides of the webs'and the upper and lower flanges of the side channel pieces and traiisoins and secured by rivets 9S. The transoms and side pieces are further held together' by a gusset plate 99 at the top and a gusset plate 99 at the bottom and secured to the flanges of the channels by rivets 100, 101 and 101. Side bearings 119 are secured to the gusset plates by rivets 120, and a center plate 121 is riveted to the transoms 96 by the rivets 122.

Figs. 7 and 8 show a modification of a pedestal and end frame construction wherein both legs are stationary and fixed. These legs 123, 124 extend vertically downward from the frame on either side of the axle box 133, being united below by tie piece 131 secured by bolts 132. The ends of the side frame are designated by 125 and 126 and each is pressed outwardly directly above the axle box to form a spring pocket 140 in which is located spring 139. Below the lower flanges of the end frame flanges 124 and 125 are formed on legs 123, 124 which bear against the flanges of the channels. T he legs extend upwardly into the space between the channel pieces at each side of the spring pocket 140, then broaden into flanges 129 above the upper flanges of the side frame, and above the channels is an arched stifl'ening rib 123, all being secured to the frame by rivets 127 and 130.

Figs. 9 and 10 show a second modification of construction with a swinging pedestal leg at the outer side. The numbers 143 and 144 are the ends of the side frame, 134 the fixed leg having under flanges 135 below the side frame, which leg at its upper end is located between the channels and broadens into ribs 147 above the upper flanges of the frame and has an arched central stiffening rib 146. The leg at the top extends downwardly beyond spring pocket 142 into the space between the side channels and is secured by rivets 145, 148. The leg 134 extends under axle box 150 and is joined to a swinging leg 137 by a bolt 136. This leg 137 is hinged between the side pieces 143 and 144 by a bolt 138. Axle box 150 will be provided with spring ledges or ribs 115', as shown in Fig. 6, to facilitate the removal of the box.

From the foregoing description taken in soms join the sides, and the pedestals, or

parts thereof, may be easily replaced should the same become broken. `fe have shown in Fig. 1 the removable pedestal legs each secured in place within a slot in the frame at the top end by two bolts. The advantage of this arrangement is clear, for the reason that should the lower end of the pedestal leg become detached or loose the two upper bolts will by taking the strains imparted by the journal box in opposite directions hold the leg in place. These bolts can, of course, be located in any position so long as they perform the desired functions. However', the outer legs may be made simply detachable and not pivoted to swing when so desired, as shown at the left in Fig. 1, where the upper end is angular.

7e have also illustrated the spring pockets inthe modified examples as extending the full depth of the beams, whereas in the main view they are somewhat more shallow. The depth of the pocket may be varied to suit conditions and, when desired, may be extended above the side pieces.

Various modifications may, of course, be introduced in practice which will not constitute substantial departures.
