CHARLES J STOVIN, OF LIBERTY MILLS, VIRGINIA.

SHOCK LOADER.

SPECIFICATION forming part of Letters Patent No. 719,158, dated January 27, 1903. Application filed Oct0ber10,1902. $erial No. 126,771. (No model.)

To (LZZ whom 271? may concern:

Be it known that I, CHARLES J. STOVIN, a citizen of the United States, residing at Liberty Mills, in the county of Orange and State of Virginia, have invented certain new and useful Improvements in Shock-Loaders, of which the following is a specification.

My invention relates to certain new and useful improvements in machines for loading bundles or shocks of cornstalks, grain, and the like upon wagons, in which they may be transported from the field to the husking or threshing machine or to the barn or other place of storage.

The objects of my invention are to provide a light, simple, and inexpensive machine of this character mounted on suitable supporting and driving wheels and which may be detachably secured to the rear portion of an on dinary farm-wagon, so that as the machine is drawn forward with the wagon past the bundles or shocks to be loaded the machine will quickly elevate and deliver the bundles or shocks into the wagon. 1

The invention consists in the construction and arrangement of parts substantially as hereinafter set forth and as illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of a shock-loading machine embodying my invention, the machine being shown attached to the rear axle of the wagon to be loaded. Fig. 2 is a plan View of the machine detached, a portion of the upper inclined platform being broken away to expose the parts below. Fig. 3 is a longitudinal vertical section on the dotted line 3 3 of Fig. 2 with part of the rear end of the machine broken away. Fig. 4B is an enlarged cross-section on the dotted line 4 4, Fig. 1, through the inclined platform and the elevating-chains. Fig. 5 is an enlarged sectional detail view of the clutch mechanism,

and Fig. l) is an enlarged perspective view of the hook.

Referring to the drawings, wherein like letters denote corresponding parts in the several figures, Aindioates the main frame,which may be of any suitable construction, but which, as shown, consists of side pieces or sills a a and cross-bars b b 17 firmly secured together, and this frame is mounted on supporting and driving wheels 13 B. At the rear end the frame A is provided with a series of rollers c 0, arranged parallel with the sills a a and forming a roller-platform C. These rollers may be of any suitable number and be supported in any convenient manner; but I prefer to mount the rollers c c, which are located between the sills a a, in bearings carried by the cross-bars b 19 while the rollers c c, which are arranged at the sides of the frame and are usually somewhat longer than the rollers c c, are supported in hearings in the outer projecting ends of the cross-bar b and in brackets d d, secured to the sills. A tongue D at theforward end of the frame, having a hook e or other attaching means, serves to connect the machine to the rear axle or other part of the wagon to be loaded.

Supported upon the frame A in an upwardly-inclined position with respect thereto is a supplemental frame E, composed of side bars e c, the lower ends of which may be bolted or otherwise secured to the inner sides of the sills a a just in advance of the roller-platform C, while the upper ends of the side bars are carried bystandardsff, likewise attached to said sills. The space between the side bars e e is floored over, the floor being preferably arranged slightly below the upper face of the said bars, so as to form, in effect, a shallow trough-shaped platform or guideway g, reaching from the roller-platform upward to the forward end of the machine, where the bundles or shocks are delivered upon the wagon. F F are endless elevating-chains, which, as shown, are provided with projecting fingers h, and these chains extend around sprocketwheels it on shaftsjj, respectively supported in bearings at the opposite ends of the inclined platform or guideway g, the upper leg of each chain passing along the top of the adjacent side bare and being guided thereon by metal strips 7.: 7t, bolted to the opposite sides of the bar. A drive-chain Z, passing around a sprocket-wheel m on the axle n of the supporting- Wheels 13 B and around a sprocket-wheel 0 on one of said shafts, preferably the upper shaft serves to drive the elevating-chains as the machine is drawn forward.

The wheels B B are so mounted on the axle that they may have independent movement,

, as when the machine moves in a curved path,

and I have indicated pawl-and-ratchet connections n between the wheels and axles, though any other well-known connections may be used.

G indicates a Winding-drum mounted on a shaft p, having its bearings in side supports q of the frame, and this shaft is driven from the axle n by a chain '1', passing around the toothed Wheels .9 and t on the shaft and axle. The drum is loose on its shaft and is adapted to be clutched thereto at will, so as to turn therewith when required, and any suitable clutch device may be employed for this purpose. As shown, the drum is keyed toa sleeve u, loose on the shaft p and having end teeth t, adapted to interlock with corresponding teeth 1) on a sleeve to, fixed to the shaft, a spiral spring 00 on the shaft tending to maintain the parts in locked position. A collar u, loose on the sleeve to, but held relatively stationary by a rod a connected to a lug d on the collar and to some stationary part of the frame, is provided at its inner end with inclined faces M, which engage oppositelyinclined faces 20 on the inner end of a collar '10 on the sleeve to and having an arm '20 A lever H, pivoted at h to a bracket y, depending from the frame E, is loosely connected at its inner end to the arm 10 while the outer end of the lever extends beyond the upper end of the inclined platform at a point somewhat below the latter.

It will be seen from the foregoing that when the parts of the clutch are in position to lock the drum G to the shaft p a downward movement of the free end of the lever H will give the collar to a cause the clutch-sleeve u to be moved lengthwise on the shaft out of engagement with the sleeve wand release the drum, while the reverse movement of the lever will permit the parts to again interlock, as will be understood.

A hoisting-rope I is secured at one end to the drum G and when in operative position extends over a guide-pulley (2, carried by a bracket f at the upper end of the frame E, along the top of the inclined platform g, around a guide-pulley g on the cross-bar b, and over the roller-platform O to the bundle or shock at the side of the machine.

The hoisting-rope may be connected to the bundle or shock in any convenient manner; but, as preferred and shown, I pass the rope through an ordinary pulley-block J and attach the free end thereof to a relatively wide flat hook K. A second or snatch pulley L, the frame of which is open on one side at Z for the ready introduction and removal of the rope, is loosely connected to the pulleyblock J, as by one or more links m and swivels m The open side of the snatch-pulley may be closed when desired by a hingeplate m.

In securing the rope to a shock, the rope being disengaged from the snatch-pulley, the end is first passed around the shock, after which the body portion of the rope is inserted partial rotation, and thereby into the open side of said pulley, which is thereupon closed to retain the rope in place. The end of the rope is now drawn through the pulleys to take up all slack and to secure a firm hold on the shock, whereupon the end of the rope is doubled back upon itself and secured by the hook K, as shown in Fig. 2.

The operation of the machine will now be apparent and may be briefly stated as follows: The machine being attached to the wagon to be loaded and being drawn up alongside of a bundle or shock, the hoistingrope I is secured to the bundle or shock, preferably in the manner already explained. The wagon and machine being then drawn forward,power is communicated from the wheels BB to the drum Grand to the chains FF, as will be understood. As the rope I is wound upon the drum the shock is dragged onto and over the rollerplatform 0 and up the inclined platform 9, the chains F F, which travel at the same speed as the rope, cooperating with the latter in moving the shock upward. As the shock is delivered from the upper end of the inclined platform to the wagon below it falls upon and depresses the free end of the lever H, thereby operating the clutch device to disengage the drum from its shaft and ar resting further movement of the rope. The rope may now be drawn back again by the attendant over the inclined platform preparatory to securing it to another shock, the drum meantime turning freely in the reverse direction, after which the drum maybe again clutched to its shaft by raising the free end of the lever H, as will be apparent.

Without limiting myself to the precise construction and arrangement of parts set forth, I claim- 1. In a shock-loading machine, the combination of a frame mounted on wheels and adapted to be secured to a wagon, an inclined platform, hoisting mechanism, means for driving the hoisting mechanism from the wheels, and a clutch adapted to be automatically operated to release the hoisting mechanism as the shock is delivered upon the Wagon, substantially as set forth.

2. In a shock-loading machine, the combination of the main frame mounted on wheels, an upwardly-inclined platform, a windingdrum, a hoisting-rope, means for communicating power from the wheels to the drum, and a clutch device adapted to be operated by the shock to release the drum as the shock is delivered from the upper end of the platform, substantially as set forth.

3. In a shock-loading machine, the combination of the main frame mounted on wheels, an upwardly-inclined platform, a windingdrum, a hoisting-rope, means for communicating power from the wheels to the drum, a clutch device for the drum, and a lever connected to the clutch and extending beyond the delivery end of the platform, substantially as set forth.
