WILLIAM F. MORROW, OF SHIPPENSBURG, PENNSYLVANIA.

IMPRQVEIVIENT IN FREIGHT-ELEVATORS.

Specification forming part of Letters Patent No. 123,189, dated January 30, 1872.

SPECIFICATION. To all persons to whom thesepresents may come Be it known that I, WILLIAM F. MoRRow, of Shippensburg, in the county of Cumberland and State of Pennsylvania, have invented a new and useful Machine for elevating and Lowering Freight; and I do hereby declare the saine to be fully described in the following specification, and represented in the accompanying drawing, of which- Figure lis a side elevation with the freight down. Fig. 2 is a plan view of the truck. Fig. 3 is an elevation of the lifting-frame. Fig. 4 is a side elevation with the freight up.

The nature of this invention relates to the application of an appara-tus composed of movable pivoted frames to an ordinary frei ght truck, whereby the freight can be hoisted from its ordinary place of deposit -to a mans shoul der, so that he may besaved the severe labor of lifting by stooping, or the reverse process may be effected by its operation to take the freight from his shoulder and lower it to the ground. It serves, also, consequently, to elevate freight or lower it to and from any other points to suit the convenience of those employing the same, and according to its limits from low to high level.

In the drawing, A is the front frame piece of an ordinary freight-truck, extended beyond the'sides and on the ends, having' axle-trees for the wheels. A is the rear end frame piece; B, the middle piece. C G are the truck-wheels; D D, the side pieces into which the end and middle pieces are fra-med and properly fastened. E E are standards, in which the ends of the frame piece G4 are pivoted; F F, the sides of the lever-frame, which are connected by cross-braces f1 j'zff, and at the base fastened securely by a tenori-joint t-o the cross-frame F4, thus making the whole frame F and F1 one bent leverframe, pivoted in the journalboxes a a,

one on each side of the truck. Fl F1 are the sides of the lever-frame, firmly joined by tenon and lnortise-joint to crossfranie. 4, and braced by cross-piece f1, above which are the roller F2 and rock-shaft F3. In F3 is fastened the bar I which is joined to I through a slot in I by a pin, i. G G are the elevator side frames having the outer end piece G1, which carries the standards G3, in which is pivoted the bottom rail H of the freight-board H. G2 is a roller, supported by the side fram es in bearings c a. G4 is the pivot-rail of the frame G, and is pivoted in the standards E H is the freight-board, which supports the bag, box, or other package, as shown in drawing. I is the rod sul'iporting the upper end of H, and is pivoted to a rock-shaft supported in brackets on the under side of H. In the lower end of I is a inortise-slit, in which the end of I is fastened by a pin, fi, through holes which are in I and l', so that proper adjustment may be made to snit the angle of the freightboard to particular purposes. K is the iron curved shoe which depends from frame G, and is formed and curved to suit the height of the truck, so that it may be readily run under the freight, as in the ordinary store-truck. a a arejournal-boxes, in which are pivoted the frame F4. f l, Fig. 4, is a brace-piece between lever-frames F F, and so beveled on the upper side as to catch the notches g2 gs of drop-pawl g g, which is pivoted on the side frames G Gat g4, and is braced by a cross-piece, g1. d d are brace-rods fastened by bolts at c c on the frames F and F1. b is a curved rod, to be used as a handle by which to move the truck. c is a platform, wagon, or railroad car, on which the package can be deposited.

Having fully described the various parts of the elevator, I now explain the method 0f operation: In Fig. l the truck with elevator attached is represented as having a bag upon the frame, a little above the ground. The 1ever-franie F is nearly vertical. By pulling F to the leit the frame F1, to which it is firmly attached, will lift up the outer end of frame G, the roller F2 bearing up the side frames G until the whole frame with the package is elevated, as shown in Fig. 4. The brace I', bearing upon roller G2, sustains the support I which holds up the upper end of board H. The droppawl g falls by its own gravity from its position in Fig. l to that in Fig. 4, and prevents the frame F from vrising by the cross-bar f catching in the notches g2 or g3 of g. The crossbar i2 on the support-bar Il extends on either side beyond the side frames G G, so that the said frame G cannot fall backward with its weight, as the strain is then thrown upon I', and its bearing-bar F3 pivoted in side frames F1. The curved rod b serves for a handle at.

'with a freight-truck, substantially as and for the purpose described.

2. The frame F F1 with roller F2, combined with the frame G, substantially as and for the purpose described.

3. The combination of the frames F F1 and G with roller G2, freight-board H, bars I and I', and drop-paw] g, all constructed substantially as and for the purpose described.
