TRUCK SKID.

Application filed November To all whom it may concern Be it known that I, CALvIN F. DUKE, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Truck Skid, of which the following is a specification.

In paper mills and warehouses, the large rolls of apers are usually handled or transported in a vertical position with the aid two-wheeled factory truck. As a result of andling in this manner considerable damage to the end of the roll is frequently caused, and it is often necessary to cut off and throw away the outer edges of the paper after it is unrolled because of the unevenness of the edge which results from the injuries suffered in trucking the roll of paper in the manner above described; and sometimes the injury is so great that the whole or a large part of a roll is rendered entirely unfit for its intended use. Handling paper in this way entails very little liftlng, however, and consequently this practice has survived in spite of the loss of paper. The finished rolls of paper come off of the paper machine in a horizontal position, and it has been recognized as desirable -to keep them inthis position while being transported, but because no satisfactory means for handling rolls of paper in a horizontal position has been available it has been impracticable to transport the rolls in this position. 7

It is the object of my invention to supply a "satisfactory factory truck to'make possible the handling of rolls of paper in horizontal position and of other objects, especially when of similar shape, with a minimum of effort and with a minimum damage to the objects handled.

In carrying out this object I have produced a factor truck designed to carry large cylindrica objects in a horizontal position; which truck is low, thus obviating the necessity of lifting the object to be handled to an excessive height; which provides a skid or incline up which the roll of paper or other similarly shaped object may be rolled; and which provides a cradle for blocking the cylinder in position on the truck so that it cannot roll ofl".

The accompanying drawing illustrates my invention: Fig. 1 is a perspective view of a truck embodying my invention, with the 8, 1922. Serial no. 599,640.

skid in position to receive a roll of aper; Flg. 2 1s a front elevation of the true with the sk1d ralsed; Fig. 3 is a longitudinal section on the line 33 of Fig. 2; and Fig. 4 is a fragmental section substantially on the line 4-4: of F ig; 2.

The truck frame proper comprises two side bars 8 and a frameoke 9 which forms the front cross bar of t e truck. Bolts 10, 11, and 12, and tubular spacing members 13, 14 and 15 surrounding them, serve to tie together and brace the side bars 8, thus making the truck frame a rigid unit. The bolt 10 acts as the axle for two rear wheels 16, which with a single front wheel 17 support the truck. For steering purposes the front wheel 17 may swing on a vertical axis. This wheel 17 is carried on a spindle 18 WlllCh in turn is carried in a wheel-yoke 19. The wheel-yoke 19 is provided with a shank 20 extending through a'central vertical hole in the frame-yoke 9. On the upper end of th1s shank is a split-collar 22 which is clamped on the yoke-shank by a bolt 23 as shown. On the front side of this collar there are provided two years 24 between which a handle-socket 25 is pivoted on a bolt 26. A handle 27 is secured in the handle socket 25, as by a set screw 28. The handle socket 25 is provided with two cars or stops 29 and 30, which serve the purpose respectively of limiting the downward and upward movement of the handle 27.

The truck skid is formed of two longitudinal members 31 spaced apart by cross braces 32 and 33. The longitudinal members 31 are similarly shaped pieces of angle iron, each bent in reverse directions at two points as shown in the Figs. 1 and 3. Substantially at the foremost bend the skid is pivoted to the truck frame and between the side bars 8 on a transverse axis, as by being provided with holes through which the tubular spacing member 14 is fixed. The bolt 11 is fixed vertically in such a position that the top surfaces of the angles 31 are a measurable distance below the top surfaces of the. side members 8. When the truck ski-d is in the lowered position (full lines Fig. 3) the longitudinal skid members extend rearward from the bolt 11 at a slight upward angle so that at the rear end of the truck frame their top surfaces are at least as high as and preferably a slight distance above the top surfaces of the truck frame side members 8. The truck skid is shaped in this manner at this point to insure that under a heavy load the truck skid will not bend and allow the ends of the truck frame side bars 8 to project into the path of the object being rolled up the skid. From this point the side bars 31 extend rearward and downward to provide an incline up which the object to be transported maybe rolled. The rear end of each side bar 31 is bevelled as shown in the drawings, to permit the upper surface thereof to come down to the ground or floor. From the bolt 11 the truck skid extends forward and upward to form an incline, which as shown is somewhat greater than that of the rear end of the skid. I have found it to be advantageous to so proportion the truck skid that its center of gravity is in rear of its axis ofpi-votal attachment to the frame.

On the tubular spacer 15 is pivoted the I latch 36. On the rear side of this latch,

teeth 37 and a stop 38 are provided. A bent rod 39 passes through a Vertical hole in the latch 36 and is secured therein by a set-screw 40. The front end of this bent rod is provided with a pedal 41 secured to the rod by a set-screw 42. A spring 43 acting between the latch 36 and the frame yoke 9 tends to swing the latch rearwardly about the tubular spacer 15. Such rearward swinging 1s stopped when the bent rod 39 strikes the lower sid of the frame yoke -9.

The operation of my invention is almost self-evident. The skid is shown in Fig. 1 and in the full lines in Fig. 3 in position to receive the roll of paper or similar object.

The ob'ect to be transported is rolled up the, incline plane formed by the rear part of the truck skid and onto the truck frame proper. Continued forward movement of the object causes it to strike the front part of the truck skid, thus raising the skid to the position shown in dotted lines in Fig. 3. This movement is limited by the stop 38 on the latch 36. The spring 43 acts to engage the latch 36 with the front edge of the cross angle 33. As the dotted lines in Fig. 3 show, when the skid is in its raised position the intermediate part between the bends of the two members 31 forms blocking which effectively prevents the cylindrical object on the truck from rolling oil. When it is desired to unload the truck, it is only necessary to depress the pedal 41. This disengages the latch 36 from the truck-skid cross-angle 33 and allows the rear end of the truck skid to drop to the floor because of the fact that the center of gravity of the truck skid is considerably in rear of the bolt 11. The object may then be easily rolled down the skid on to the floor.

I claim as my invention:

1. In combination, a load-carrying truck frame, a floor-engaging skid pivotally mounted on said frame for facilitating the rolling of articles onto said frame, and a supporting wheel for said truck frame on each side of the axis of pivotal mounting of said skid.
