' BRICK-CAR.

To all'whom. it may concern:

Be it known that I, CLARENCE M. STEELE, a citizen of the United States, and a resident of Statesville, in the county of Iredell and State of North Carolina, haveinvented certain new and useful Improvements in Brick- Cars, of which the following isa specification.

This invention is an improvement in lift cars for use in handling brick and has for an object among others, to provide a novel construction which can be easily operated to set the bed of the car up or down in order to lift or lower the load and which will be found convenient in handling brick and other material on pallets.

The invention also has for an object to provide a lift car having only one deck making it flexible, thus allowing the wheels to follow an uneven track.

The invention consists in certain novel constructions and combinations of parts as will be hereinafter described and claimed.

Inthe drawing Figure 1 is a longitudinal section along line 11 of Fig. 2. Fig. 2 is an end view of a car embodying my invention, and Figs. 3 and 4 are detail views.

In carrying out my invention, I provide a main frame having side rails A bolted at its ends to hearing frames B which are in the nature of hangers depending from the main frame and providing at C pivots for, what for convenience of reference, I term the rockers -D, of which I employ one at each end of the car. 'These rockers are alike except that they are rights and lefts. and they are pivoted at C so they may rock in effecting an elevation and lowering of the bed A, in the use of the invention. These rockers C-have upwardly projectinv arms G provided with worm segments 6 and the rockers also have the projecting arms C at an angle to the arms C with the arms 0 of the rockers at the opposite ends of the car projecting in reverse directions and these arms C? support at C" the axles of the wheels E.

' To the main frame and preferably to the end frames B thereof, I journal the operating shaft F which is rovided with worms G made rights and lofts meshing with their respective worm segments C as best shown iirFig. 1 of the drawing. By turning the shaft F which may be conveniently accomplished by the handle F, the worms G meshingwith their Segments, "will tilt the rockers Specification of Letters Patent. 'Patented Dec. 27, 1910.

on their pivots C in such manner as to raise and lower the bed of the car.

- By the described mechanism, it will be noticed I simplify the construction ofthe car, reduce the number of parts and make the car lighter, easier handled and more flexible than with the cars ordinarily in use.

The operating shaft has its end thrust balanced, thus eliminating friction, so that when the shaft is turned, the bearing frames in the form of rockers are swung on their pivots at C to raise and lower the car frame as desired.

It will be noticed that by the described construction, I furnish a lift car having only one deck which makes it flexible and allows the wheels to follow an uneven track.

In the special construction of mainframe shown, I provide the two one B at each end of the car, p'rovi ed with the bearings for the worm shaft and connect these frames b the two side bars which may be securely bo ted in place. I also make the rockers each in one piece and pivot the same to the end frames as before described. Also by the special construction of worms and segments, I am able to tilt the two rockers in unison, thus counteracting the rolling. effect of the wheels on the track as the load i being lifted or lowered. 1

I claim: I

1. The; combination substantially as described, of a main frame, hanger frames depending at the opposite ends of the main frame, rockers pivoted to the hanger frames and having arms provided with worm segments and also arms adapted to support axles, axles carried by said arms and provided with wheels, an operating shaft journaled in the end frames and provided with worms meshing with the segments of the rockers, the worms and segments at the opposite ends of the frame being one right and the other left, substantially as set forth.

2. The combination of a framing, rockers pivoted intermediate their ends thereto and having crank arms projecting from their pivots and provided with worm segments and also having crank arms projecting fromthelr plvots at an angle to sald first crank.

and a shaft journaled to theframing and having worms meshing with the worm segments, substantially as set forth.

iece frames crank portions provi 3. The combination of a framing having end frames provided with cross bars having midway between their ends bearings for a worm shaft, the said end frames having depending hangers rovided with bearings, a rocker pivoted at itsends in the bearings of the hanger and havin at its ends projecting ed with bearings near their free ends, axle shafts journaled in said bearings, "crank arms projectin from the rockers midway between their en s and at an angle to the armshaving bearin s for the axle, said intermediate crank arms eing provided with worm se ents and an operatin shaft journaled in 5:; cross bars of the en frames and having worms meshing-with the worm segments of the rockers,'substantially as set forth. Y

4. The combination of a frame, hangers depending from the frame adjaeentthe ends thereof, rockers having at their ends crank portions provided with axial ournaled in said bearings the rockers being provlded between their en s with crank arms projecting at an angle to said first crank :arms and having worm segments and an operating shaft having worms meshing with' said segments, substantiall as set forth.
