DUMPING OR UNPACKING TRUCK.

Specification of Letters Patent.

Patented Aug. 8, 1911.

To all whom it may concern:

Be it known that I, WILLIAM VmTUs ELLIS, a citizen of the United States, residing at I-Iuntingdon, in the county of Huntingdon and State of Pennsylvania, have invented certain new and useful Improvements in Dumping or Unpacking Trucks, of which the following is a specification.

My invention relates to dumping or un packing trucks which are designed to receive the contents of a case of merchandise by being inverted upon the top of such open case, and then to receive such contents by tipping the case over so that the said contents will freely pass to the floor of the truck. Such a truck is illustrated in my Patent No. 9453,0413, dated Feb. 1, 1910.

The particular invention forming the subject matter of this present application will be found useful in connection with the truck illustrated in my said patent, and has for its object to provide portable lifting and moving means for the said truck, whereby its usefulness is increased.

I have illustrated a desirable form in which my invention may be embodied in the accompanying drawings, wherein Figure 1 is an elevation of the said truck illustrating my invention applied thereto; Fig. 2 is a section on the line 22 of Fig. 1 looking to the left. Fig. 3 is a detail partly in section illustrating the position assumed by the parts when the lifting and moving device is first applied; Fig. A is a detail front view of the said lifting and moving device partly broken away. Figs. 5 and 5 are detail side and end views of the axle, and Figs. 6 and 6 are similar cletail views of the locking dog.

In carrying my invention into effect, I have provided the truck of my former patent with a rear axle which may be freely turned horizontally, and in connection therewith I make use of a separable frame having means for engaging the said axle and carrying a single wheel and a handle whereby the axle-engaging means are in serted in place and upon a pressure downward of the handle, the wheel is brought into place under the truck and the same is lifted and easily propelled, the single wheel acting in connection with the revolving axle to direct the movement of the truck to any desired place.

In the particular form in which my invention is illustrated in the accompanying drawing, the lifting and propelling means are shown as consistingof two plates A which are similar in all respects, and which may be made of any desired material, such as malleable cast iron, which I have found well adapted to the purpose. Each of these plates has a handle post a and a supporting post a A convenient way of supporting the handle B, I find to be by attaching the said handle to a plate (1. which connects the handle posts together. A similar connection a between the said plates A serves as a support or axle for the wheel 0. The supporting posts a are each forked at their upper ends at a forming bearings adapted to receive trunnions for a purpose presently to be described. Each of these posts is likewise provided on its forward side with a notch a and the material of the plate above said notch is preferably extended as at a forming a locking shoulder.

Upon the rear under side of the dumping truck illustrated in my said patent I provide means for supporting the bearing, as for instance, by an angle iron D. Depending from this angle iron and attached thereto by suit able bolts, is a rectangular frame cl which supports a shaft E. The said shaft has an upwardly projecting stem e which passes through the frame [Z and may enter a hole in the angle iron D for the purpose of holding the said stem perpendicular. Suitable means may be employed for holding the shaft in place, as for instance, a pin 6 which passes through the stem 6 above the frame (Z. It will be perceived that the foregoing construction permits the said shaft to freely turn horizontally. I have provided means upon the said shaft for receiving the bifurcated ends of the supporting posts a consisting of a reduced shoulder 6 upon each side forming trunnions which have bearings in the forked ends a of the said posts a Suitable means may be provided for holding the lifting device and the dump ing truck together, as for instance, by a swinging bail-shaped locking dog F which has its ends turned into loops, and the said loops are received one upon each reduced end 6 of the axle E.

It will be observed that the handle post and handle and the supporting post are at an angle to each other in the case shown,

this angle being approximately 45. The handle, however, I prefer to bend at Z) so as to increase such angle from the point of the bend outward. The said handle and supporting posts, however, may be otherwise related to each other.

In using my device the bifurcated ends of the supporting posts will be caused to embrace their bearings upon the shaft substantially as illustrated in Fig. 3, whereupon downward pressure being exerted upon the handle the truck will be raised and the wheel 0 will be caused to pass under the rear portion of the truck and the dog 1* will swing into the slot at and behind the shoulder a, and will tend to prevent the truck tippingforward. The parts being in this position the truck may be easily propelled to any desired locality upon the forward wheels which rest upon the ground. The rear of the truck will then be lifted from the ground and will be supported by the wheel C which, owing to the turning of the shaft IE, will cause the truck to be easily guided to any desired point. Should it be desired to leave the lifting device in position, the truck may simply be lowered and permitted to rest upon its bottom frame, whereupon the wheel will remain in position as the weight of the handle will keep the lifting device from passing out of connect-ion with the rear end of the truck. The lifting device might easily be locked in forward position by causing the wheel to pass in front of the axle and providing a stop 011 the frame to engage the supporting post and thereby lock the device in position with the truck lifted.

Although I have described with some particularity the mechanical details of construction of my lifting device, it is not therefrom to be assumed that I regard my invention as limited in its practical embodiment to such details. The essential details of my invention may be changed and equivalent devices substituted within the limits of the appended claims.

The illustrated means for causing wheel C to turn easily, embracing shaft E, are practicable means for accomplishing the purpose, but other and equivalent means might be employed and I do not regard my invention as limited to the employment of such means illustrated.

What I claim is 2- 1. In an unpacking truck, hand-operated means for propelling and guiding the truck and for lifting one end thereof, comprising a frame, a single wheel mounted therein, a handle attached to said frame at an angle which permits it to extend upwardly and rearwardly when the frame is in supporting position, and adapted to operate said frame for lifting and to guide and propel the same, a separable swivel connection between the frame and the truck whereby the frame may be turned relatively to the truck, permitting the frame to be freely separated from the truck, the said swivel connection adapted to be connected before the truck is raised and to lift one end of the truck when the handle is depressed and swing the frame to supporting position beneath the truck, said frame adapted to be freely disconnected from the truck by raising the handle, where upon the truck will be lowered.
