IVILLIAM F. MORROIV, OF SHIPPENSBURG, ASSIGNOR OF ONE-HALF OF HIS RIGHT TO WILLIAM A. MIDDLETON OF NEVVVILLE, PENNSYLVANIA.

IMPROVEMENT IN FREIGHT-ELEVATING TRUCKS.

Specification forming part of Letters Patent No. 130,062, dated July 30, 1872.

To all whom it may concern:

Be it known that I, WILLIAM F. MoRRoW, of Shippensburg, county of Cumberland and State of Pennsylvania, have invented certain new and useful Improvements in Freight-Elevators; and do hereby declare that the following is afull, clear, and exact description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon making a part of this specification.

The nature of my invention consists in certain improvements upon the freight-elevator for which Letters Patent N 0. 123,189 were granted to me January 30, 1872, as will be hereinafter more fully set forth.

In order to enableothers skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which Figures 1 and 2 are sideviews of my-machine in different positions, and Fig. 3 is a plan view of the same.

A represents the truck-frame, provided on each side at the front end with a wheel, B. On each side of the truck-frame A, at a suitable point, is secured a handle, 1), which is braced to the rear end of said frame by a rod, a, and the two handles are connected together by a rod, b. Near the rear end of the truckframe is pivoted a frame, 0, the front end of which rests upon a roller, d, in the outer end of another frame, E, which is also pivoted in the truck-frame A a suitable distance from the front end of the same. In the frame A is pivoted a third frame, G, which passes through the frame 0, and rests on a roller, e, in the same. At the outer end of this frame G is a roller, f, mounted in outward-projecting ears, for the purpose of supporting an ordinary truck-frame, H, which has no wheels, and is hinged or pivoted at the outer end of the frame 0, this hinge or pivot being situated a suitable distance from the front end of said truck-frame H. In the upper truck-frame II is pivoted another frame, I, which may be thrown forward, as shown in Fig. 1, or folded back when not needed for use. Upon the journals of the frame E, on the outer sides of the lower truck-frame A, are placed two levers, J J, at or nearly at right angles, which levers are, at one or more places near their outer ends, connected by suitable rounds. At the lower end of each lever J, on the front side, is attached a toothed or ratchet bar, 1', in which a pawl, h, may be. engaged, the two pawls h h being placed upon the ends of the same rod or shaft, so that when one is turned the other will also turn in the same direction. The upper truck-frame being hinged or pivoted, its rear end can be raised so as to bring the front end down to the ground for receiving the box, barrel, or other article to be moved. The truck-frame H is then brought down again nearly horizontal, when it is held there by a hook, it, from the rod b, or by any other suitable catch, automatic or otherwise. The whole truck can then be moved to the desired place by the use of the handles D D; or it may be used as an express-truck, for moving trunks or a number of other articles, by throwing out the frame I, as shown in Fig. 1.

If desired to elevate the load for any purpose whatever, the levers J J are pulled down, as shown in Fig. 2, and, these levers being connected with the frame E by rods m m, this frame is raised correspondingly to the depression of the levers. The raising of this frame E causes, by means of the frames 0 and Gr, the truck-frame H to be elevated horizontally, or nearly so, when the load on the same can readily be deposited at any height desired. The pawls h h, being thrown down against the ratchet-bars i i, hold the load at any desired height until deposited. In like manner articles may be taken from a higher place and lowered to the ground or any intermediate position.

When the load is elevated L-shaped catches n h on the sides of the upper truck-frame H, pass under the projecting ends of the upper cross-bar of the frame G, thus holding the truck-frame in position, preventing thesame from tilting.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The arrangement of a truck, A B, of the frames 0, E, and G, with rollers e, d, and f, respectively,substantially as and for the purposes herein set forth.

2. In combination with a truck, A B, and hinged frames 0 E G, arranged as described, I claim the handles D D, attached to the truckframe A, and braced by rods a a and 1), substantially as and for the purposes herein set forth. I

3. A truck-frame, H, hinged or pivoted to an elevating apparatus moving on wheels, substantially as herein set forth.

4. The upper truck-frame H, provided with the folding frame I, and arranged in combination with the frames 0 E G and truck A B,

- and held by the hook k or its equivalent, substantially as and for the purposes herein set forth.

5. In combination with the leversJ J for operating the elevating apparatus herein de-. scribed, the ratchet-bars i i and pawls h h, substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 19th day of July, 1872.
