DUMP-CART SUPPORT.

Original application filed December 28, 1911, Serial No. 668,342.

Specification of Letters Patent.

1912. Serial N0. 687,647.

To all whom it may concern:

Be it known that 1, JAY B. RHODES, acitizen of the United States, residing at Kalamazoo, in the county of Kalamazoo and State of Michigan, have invented certain new and useful Improvements in Dump-Car Supports, of which the following is a speci fication, reference being had to the accompanying drawings.

My invention relates to dump cars, and has for its object to provide certain improvements in rocking supports for the car bed by which the bed is prevented from being displaced either longitudinally or laterally. I accomplish this object as illustrated in the drawings and as hereinafter described.

That which I regard as new is set forth in the claims.

In the drawings, Figure 1 is a side view of a dump-car illustrating the application of my invention thereto; Fig. 2 is an enlarged detail illustrating one of the rockerbearings by which the car bed is prevented; Fig. 3 is a view showing a modified form of the same type of bearing, being a transverse vertical section; Fig. 1 is a view of one of the bearings for preventing endwise displacement of the car bed, partly broken away; and Fig. 5 is a vertical section on line 55 of Fig. 1.

Referring to the drawings,6 indicates a car bed of the type shown and described in my application Serial No. 668,342, filed December 28, 1911, of which this is a division. Said bed is supported at points along its longitudinal central line by a series of rocker-bearings 7-8, which bearings are supported by longitudinally extending beams 9 earned by the usual trucks 10.

Such bearings-the construction of which is best shown in the remaining figures are of two kinds, one designed to prevent lateral displacement of the bed in dumping, and the other to prevent longitudinal displacement thereof. The former are best shown in Figs. 2 and 3.

1n the construction shown in Fig. 2, there is a base-plate 11 which rests upon and is secured to the beams 9, said base having a channel 12 in its upper surface bounded at its sides by lugs 13, thus forming a rockerbearing. 14 indicates a rocker adapted to lateral displacement offit in the channel 12 and to rock therein so as to carry the bed over to one side or the other for dumping purposes. Said rocker is provided with an upwardly-projecting web 15 having a socket 16 which receives a longitudinallyextending beam 17 shown in dotted lines in Figs. 2, 3 and 1. Said beam is secured to the under side of the car bed, preferably in an inverted channel-bar 18. 19 indicates links at opposite sides of the rocker it, said links embracing pins 20-21 carried, respectively, by the rocker 14 and the base 11, as shown in Figs. 1 and 2. The links 19 are long enough so that they may move longitudinally to a limited extent to permit the necessary rocking of the rockers 1 1 as the car bed is tilted, but they are not long enough to permit the rockers to be displaced and consequently act to prevent the rockers from jumping out of the channels 12.

In the construction shown in Fig. 3, instead of employing two links 19 at the sides of the rocker, I employ a single longitudinally movable link 22 fitted in recesses 232 1 provided, respectively, in the rocker serve the same purpose as the pins 20-21. In this construction the link 22 is concealed and is protected, and, moreover, a single link only is used, so that in many respects it is preferable to the construction shown in Fig. 2. The rockers which prevent endwise displacement of the bed are similar in several respects to the rockers 1 1 and. 145*, there being a base 25 having a channel 26 in which works a rocker 27 having a web or tongue 28 by which it is connected with the car bed. The rocker 27 is provided with a recess 29 in its under surface which receives a tongue 30 rising from the base 25, in the channel 26, as best shown in Fig. 5. By this construction the tilting of the bed is not interfered with, but it, of course, cannot move endwise.

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

1. A rocker-bearing, comprising a base having a channel in its upper surface, a rocker adapted to fit and rock in said chan nel, and a longitudinally-movable link con nected with said rocker and with said base for limiting the movement of said rocker in either direction.

to overlie the recess in the base, a link in said recesses, a pin connecting said link centrally with said rocker, and means loosely connecting the llnk With the base'so that it Copies of this patent may be obtained for may move longitudinally When the rocker is rocked.

4. A support for dump oars, comprising a base having a recess,a rocker adaptd to rock on said base and havinga recess adapted to overlie the recess in'the base, a link fitted in said recesses, and pins, connecting said link with said rocker and with said base, said link being movable longitudinally of itself when the rocker is rocked. r,
