Patented May 13, 1930 PATENT OFFICE FRED A. LUNDAHL, OF MOLINE, ILLINOIS TOY DUMP CART Application filed March 24, 1924, Serial No. 701,403.

My invention has reference to a toy dumpcart, which is more specially designed for use in sand-piles, play-grounds, and the like, but which can also be adapted for use with .5 larger vehicles of the class named. The chief purpose thereof is to provide a simple and novel means for elevating the body of the cart, and holding the same in elevated position.

In the drawings:

Fig. 1 is a side elevation of a dump-cart equipped with the device.

Fig. 2 is a similar view of the rear part of the cart, with the body in elevated position.

Fig. 3 shows the rear part of the frame, in

plan view, with the body removed.

The reference number 1 indicates the frame of the cart, supported on forward carrying wheels 2 and rear carrying Wheels 3. 4 represents the hood, and 5 the seat, in rear of which the body portion 6 is pivotally supported on the frame, as at a. WVhen in a lowered position said body rests upon a pair of cross-plates 1.

Rotatably mounted beneath the frame 1, is a cross-shaft 7, at a central point of which is fixed a crank-wheel 8, to the opposite faces of which are pivoted the forward ends of arms 9, the rear ends of which are pivoted 3% to the short ends of a pair of levers 10, rockingly mounted on a shaft 11 supported on the frame 1. The levers 10 are spaced apart, the arms 9 diverging rearwardly, as shown, in order to conveniently connect therewith.

The long ends of the levers 10 are provided with lugs 12, for engagement with channel plates 13, fixed to the lower face of the box 6. TVhen the shaft 7 is rotated in a direction to move the arms 9 forwardly, the levers 10 are elevated, the lugs 12 sliding in the channel plates, and the box 6 being gradually raised by said levers, until the contents of the box slide from the rear end thereof, by force of gravity.

4? Fixed on one end of the shaft 7 is a ratchetwheel 14, in rear of which is pivoted thereon a plate 15, to which is pivoted a hand-lever 16, as at b. The end of said lever is fitted with oppositely disposed teeth 17, adapted for alternative engagement with the teeth of Renewed April 3, 1926.

the wheel lat. By swinging such lever towards the rear, the rear tooth 17 is caused to engage said wheel, and a continued movement of the hand-lever operates to rotate the shaft 7, in a direction to elevate the levers 10 and i box 6. If it is desired to hold the box in this position, this can be done by engaging a ratchet-wheel 18 on the shaft 7 with a catch 19, pivoted to the frame 1. The box can be lowered by disconnecting the tooth 17 from 43-1? the wheel 14, and tipping the lever 16 forwardly 011 its pivot until the other tooth 17 engages the teeth of said wheel. This operates to connect the lever 16 and shaft 7 so that a continued forward movement of the lever will rotate the shaft in a direction to lower the levers l0 and box supported thereon.

If it is desired to secure the box 6 in its lowered position, this can be accomplished by means of a catch 20, pivoted to the side of the frame on the opposite side of the wheel 18 from the catch 19. and adapted to engage said wfheel to prevent a rearward movement there- 7 o 5 The operating mechanism is simple and compact, and the lifting power is applied equally at opposite sides of the box, so that there is no danger of the box tipping to one side or the other.

What I claim, and desire to secure by Letters Patent, is:

1. In a toy clump-cart, a portable frame; a wagon body pivoted thereto; a pair of levers fulcrumed on said frame in spaced relation and having depending short arms, and having a slidable connection with the wagon body; a shaft rotatably mounted on said frame; a crank-wheel fixed to said shaft; a

pair of arms pivoted on opposite sides of said crank-wheel having bent portions adjacent to said shaft, and diverging rearwardly to pivotal connections with the short arms of said levers; a ratchet-Wheel fixed on said shaft; and a hand-lever, rockingly mounted, and adapted for alternative engagement with the teeth of said ratchet-wheel, to turn the same in one direction or the other, at will.

2. In a toy, the combination with a wheeled frame; of a dump body having one end por- 10c tion pivotally connected with one end portion of said frame; a transversely extending operating shaft rotatably mounted in said frame adjacent the forward portion thereof, said shaft having an operating element intermediate its ends; means for rotating said shaft; a pair of laterally spaced longitudinally extending bell crank levers, each of which is pivotally mounted adjacent its elbow on said frame at a point between the pivotal n'iounting of said body on said frame and said operating shaft, one set of arms of said bell crank levers being movably connected to the under surface of said body porion in spaced relation; and links connected to the free arms of said bell crank levers, said links converging toward each other and said operating element; and means connecting the adjacent ends of said links with said opera-ting member to effect longitudinal movement of said links to swing said dump body on 1t-s pivot.

In testimony whereof I my slgnature.

FRED A. LUNDAHL.
