LOADING AND UNLOADING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 358,558, dated March l, 1887.

Application led February 27, 1886. Serial No. 193,465. (No model.)

To all whom it may con/cera:

Be it known that I, KIRKE E. Litrnnor, a citizen of the United States, residing at Afton, in the county of Union and State of Iowa,have invented certain new and useful Improvements in Apparatus for Loading and Unloading, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l represents a rear perspective view of my improved apparatus Fig. 2 is an enlarged transverse sectional view on the line .fr of Fig. l.

My invention relates to devices for loading or unloading hay, stones, barrels, or other articles; and the same consists in the construction and combination of devices, which I shall hereinafter describe, and specifically point ont in the claims.

To enable others skilled in the art to make and use my invention, I will now describe its construction and the manner in which I have carried it out.

In the said drawings, A represents a suitable body provided with longitudinal sills a, and transverse sills b b; and B B represent the supporting-wheels, which are mounted upon the axles C, as shown in Fig. l.

In constructing myapparatus I mount upon the rear transverse sill, and at or near thclongitudinal center of the wagon-body, and securely brace thereto, an upright post, D, com, posed, preferably, of gas-pipe or other hollow tubing, having one ofits sides slotted at 2, for a purpose I will now describe.

Located within the post D is a pipe or tube, E, whose exterior diameter is slightlyless than the interior diameter ofthe said tube,whereby the pipe or tube E may be vertically moved within the post, and. may be adjusted to accom modate itself to different heights,in amanner to be hereinafter described.

The lower end of the pipe E is attached to a swiveled connection, a', to which is secured a cord or chain, e,which extends upward over a guide-pulley, 3, secured to the post D, near its top, and thence downward to a drum, c, j ournaled within the vehicle-frame. The shaft of this drum c is provided with a crank or handle, c', for operating the same, to cause the pipe E to be moved vertically upward or downward within its post. By these means I am enabled to adjust myloading apparatus to racks of different heights when employed for handling hay, straw, Ste-a feature that is greatly desired, and readily accomplished by the simple winding of the cord or chain c upon its drum until the desired height is obtained, when the pipe E may be held in its adjusted position by means of a suitable pawlandratchet mechanism.

In the extreme upper end of the pipe E is mounted a pulley, 5, to the pivot-pin of which is pivotally attached an arm, E, extending at right angles to the vertical line of the tube and carrying on its outer end a pulley, 6, as shown. The arm i" is also provided with a series of stops, 7, which, in conjunction with a rod, F, pivoted at 8 to the tube E, enables the arm E to be raised from a horizontal to an inclined position, thereby further increasing the distance the load may be elevated.

At the rear end of the vehicle is mounted a transverse shaft, G, carrying at or near its center a drum, H, around which is wound a cord or chain, f, which extends from the drum upward through the hollow post D, pipe E, and arm E', over the pulleys 5 and 6, and has attached to its outer end a suitable fork or other implement, (not shown,) which engages and holds the hay or other article to be elevated.

The shaft G has loosely mounted near its ends sprocket-wh eelsKK, provided with. hubs g, the outer portions of which have serrated faces, which engage similar faces formed on suitable clutchrollars L, which are keyed or otherwise rmly secured to the shaft. The inner portions of the hubs g are provided with annular grooves, which are engaged by the outer ends of suitable sliding levers or rods, M, while the inner ends of said levers are attached to the end ofacord or chain, h. The said cord or chain, after being attached to the levers, passes through suitable guides, k, and passes to the front portion of the vehicle-body under a pulley, 9, mounted on the front transverse sill, and thence extends upward to a drum, I0, in upper portion of a frame, N, pivoted at its base to the longitudinal sills of the vehiclebody. The shaft Z of the drum 10 has mounted thereon a ratchet, 11, whose movement is controlled by a suitable pawl, with which it is engaged. A crank-handle, 12, on the end of the IOO ' shaft Z, when operated, winds or unwinds the cord upon the drum, and causes the serrated faces of the sprocket-wheels to engage or disengage the serrated faces of the clutch-collars, L thereby permitting the cord or chain j", which carries the fork or implement, to be wound or unwound, and the article elevated o'r the fork lowered, as desired.

To cause the clutch mechanism previously served the rear supporting-wheels, B', are secured to and operate sprocket-wheels O, which are connected with the sprocketwheels K K by means of drive-chains I, as shown.

From the foregoing description it will be observed the operation of my apparatus will be substantially as follows: A team being hitched to the wagon, I ordinarily employ a boy to drive, a man to load, and boy or man to place the hay-fork when handling hay in the'cock or bunch of hay to be loaded. The

man on the ground places the hay-fork in the cock or bunch, using preferably a four-tined grappling-fork, the boy starts the team, and the supporting-wheels B revolving the endless chains (the machine being in gear) and the drum, thereby causes the rope j', that runs through the post and tube and to which the fork is attached, to be wound upon the drum H. When the hay is lifted high enough, the operator on the wagon pulls a rope, It, attached to the outer end of arm E', and swings the hay over the load. The man on the ground then trips the fork, letting the hay drop on the load. The boy then turns the handle l2, thereby throwing the machine out of gear and permitting the fork to drop to the ground. The team is driven to and stopped at the next cock or bunch, and the process is repeated as before. In ordinary work I only gear the machine to one of the supporting-wheels; but when farmers put up very large cocks it is better to gear to both hind wheels.

To unload after driving into the barn, if it be desired to place the hay in the top of a mow, first raise the derrick-arm E to its full height by adjusting the brace-rod F, and then raise the tube E by turning the crank c. It is now evident that when the team is attached to the rope f and started the several mechanisms described operate to elevate the hay or other material.

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

1. A wheeled frame having a tubular derrick mounted thereon, in combination with a transverse shaft, G, having a drum, H, immediately below the derrick, the clutch-collars L fixed upon the shaft and having serrated faces,

kthe loosely-mounted sprocket-wheels K K, the

levers M, and ropeh, for operating to unclutch said wheels, and the main drive-wheels having sprocket-wheels O, connected with the wheels K K, and driving the shaft,whereby the load is elevated, substantially as herein described.

2. A wheeled frame having a fixed hollow post, D, in combination with the tubular section E, adapted to be vertically adj usted within the post, a tubular horizontal section or arm, E, pivoted to the vertical arm by the pivotpin 5, a pulley upon said pivot-pin and within and-ratchet mechanism for adjusting the derrick vertically, substantially as herein described.

4. Awheeled frame havingaderrick mounted thereon, a transverse shaft at ythe rear of the frame having the fixed clutch-collars L, and the loosely-placed sprocket-wheels driven by power derived from the main drive-wheels, in combination with the sliding lever or rods M, the projections or guides m, the rope connected with and operating both levers, whereby the sprocket-wheels engage or disengage the fixed clutch-collars L, a pulley, 9, and a pivoted frame, N, at the front of the main frame, having the drum I0 and operating-crank handle l2, substantially as herein described.
