WAREHOUSE-TRUCK.

SPECIFICATION forming part of Letters Patent No. 239,934, dated April 12, 1881-.

Application filed October 25, 1880. (No model.)

To all whom it may concern:

Be it known that I, DAVID M. COLE. residing at Elgin, in the county of Kane and State of Illinois, and a citizen of the United States, have invented a new and useful Improvement in Stove and Warehouse Trucks, of which the following is a full description, reference being had to the accompanying drawings,in which- Figure 1 is a longitudinal section; Fig. 2, an under or bottom View; Fig. 3, a top or plan view; Fig. 4, a side view with the platform down; Fig. 5, a similar view with the platform raised and Fig.6, aside elevation, showin g the method of using the article to be loaded asafulcrum when forcingthe platform under it.

This invention relates to stove-or warehouse trucks, and has for its object an improved construction and operation of trucks having varying elevations in use, to dispense with a secondary frame or horizontal platform, and the using of arms or hooks as a fulcrum for forcing the platform under the articles to be loaded, or forcing the articles onto the platform, or partly both, so that a single person can handle heavy articles; audits nature consists in an improvement in hanging and connecting the wheels, in applying loading-rods parts, as hereinafter set forth and claimed as new.

1n the drawings, A indicates the main frame or platform; B, the wheels; G l), the handle; a, the cranked or lever axles b, the axle connecting-rods; c, the connecting-bail d, the connecting-hooks; e,theloading rods or hooks f, anti-friction rollers, and 9 stops.

The platform A is made of wood and of any desired dimensions. The form shown is one designed for handling stoves, and for this purpose the platform is made narrow enough to pass between the stove-legs.

The wheels B are arranged so that their tops will come just beneath the lowest level of the top of the platform, and their spindles are near the middle of the crank of the axles, as shown; but'the point of the spindle attachment may be varied according as a slight or a considerable rise of the platform is desired. For most ones a slight rise will be found sufficient in trucks built for a special use.

The axles are pivoted or journaled to the platform at a, and are made in the form shown.

As shown there are four; butit is evident that they may be made to extend across the truck, so that the opposite wheels would be on a single axle having cranked ends. It will also be evident that when they are made in this modified form the two may be connected by a single rod, 1), instead of two, and I propose to make and connect them either way.

At the handle end I attach a bail or rod, 0, which connects with the hook or hooks d of the lever-handle. When the platform is in the position shown at Fig. 5 the hooks. d are easily connected with the bail c for use, or disconnected for storage or transportation, and to prevent the bail from slipping out a pin may be inserted in the hook (I, so as to hold the bail in place when connected.

For a cheap truck, instead of using thehooks d. a cross-rod may be used and the bail be made of a single rod having a hook or an eye on its end to engage with such cross-rod on the lower end of the handle.

The handle is best made of the bars 0 and rounded cross-bar D, but its form is not material, as they may be made of two common plowhandles.

For many purposes the truck is complete Without the loading-rods 6; but for handling heavy articles their use will be found advantageous, and they are either made to go partly around the article, as shown, or when used for handling boxes they may be made with sharpened points, so as to take hold of the sides of rough boxes or casings; and they may be i when by lifting the handle the article is raised.

If the truck is to be forced under, or the article loaded, then the lifting of the handle tends action of the wheels on the floor is such that the truck-platform is both lifted and advanced.

By attaching the hooks e on the inside of the bars Gr they may be attached at their lower ends so as to act as fulcra for the leverhandle, or as blocks for the wheels, and when attached above the lever pivots, as shown, then these rods are advanced for a new hold, which is made effective for loading when the handle is pressed downward. When the article is loaded the axles a turn alittle back of the vertical line, so as to rest against the stops, 9, and when the axles are in this position the truck may be moved around upon the wheels B without letting the platform down.

What I claim as new, and desire to secure by Letters Patent, is as follows: 3
