Specification of Letters Patent.

Patented Dec. 25,1917.

Application filed May 5, 1917. Serial No. 166,633.

To all whom it mayconcern:

Be it known that I, ARTHUR L. HEWITT, a citizen of the United States, residing at Boyne Falls in the county of Charlevoix and State of Michigan, have invented l((2rafollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the lettersand figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in agricultural machinery, and particularly to machinery known as manure Spreaders.

The important feature of the invention residesin the provision of a device of this character adapted to be employed with the usual wagon frame now in use.

A further object is to provide a movable bottom and means independent of the wheels of the wagon to which this device is applied for operating the movable bottom.

A still further object is the provision of means for automatically throwing the operating means into and out of operation.

The invention comprises various details of construction, combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claim.

I illustrate my invention in the accompanying drawings, in which 2-- Figure 1 is a plan view of the invention.

Fig. 2 is a longitudinal view of the device taken on line 22 of Fig. 1.

Fig. 3 is a rear elevation.

Fig. 4 is a transverse sectional view.

Fig. 5 is an enlarged plan view of the clutch mechanism.

Fig. 6 is an enlarged detail view of the clutch mechanism.

Reference now being had to the details of the drawings by numeral, 1 indicates the side boards of the body of the manure spreader, the lower ends of which are connected to the skeleton frame comprising side rails 2, to which are connected the cross bars 3. Supported in spaced relation with the side rails 2 and disposed on the inner sides of the side boards 1 are the supporting rails 4 and 4, forming the track for the movable bottom 5, comprising a plurality of con nected sections 6 and a head board 7 through which extends an eye bolt 8 to which is connected one end of the flexible connecting member 9, the opposite end thereof having connection with the opposite end of the flexible bottom as at 10, the intermediate portion of the flexible member 9 passing over the pulley 11, slidably mounted on shaft 12' and comprising sleeves 12 and 13' having clutch faces 12 and 13 at the respective ends thereof. Supported in spaced relation with the shaft 12 is a drive shaft 14 having sprocket wheel 15 keyed or otherwise secured thereto, adjacent one end thereof, whilea similar sprocket 16 is keyed adjacent the opposite end thereof. The sprocket wheel 16 has communication with the sprocket wheel 17 which in turn is rigidly secured to the shaft 12 through chain 17, said sprocket wheel also having clutch face 18 adapted to cooperate with the clutch face 13 of the sleeve 13 for communicating motion thereto. A clutch face 19 is also keyed to the shaft 14; and cooperates with clutch face 20 formed on the slidable sleeve 21, said sleeve carrying a sprocket wheel 22 havin communication with the engine 23 by suitable means, not shown, and it will be seen that, when the lever 24 is moved in one direction, clutch faces 19 and 20 are brought into engagement with each other with the result that the shaft 14 is brought into operation.

At the opposite end of the shaft 12 is a sleeve 25 having clutch face 26 and carrying a sprocket 27, having communication with the sprocket wheel 15 through chain 28. Pivotally supported on the frame is an operating lever 29 having a forked end 30, engaging the flange 31 on the sleeve 12, the opposite end of the lever 29 being pivotally connected to the lug 32' formed onthe sliding arm 33, operating through guides 34 secured to one of the side bars 4:, one end of said arm 33 extending upwardly and forming an abutment to be engaged by one end of the bottom 5 for operating the sleeve 12 and consequently throwing the clutch faces 12 and 26 out of operative relation.

On the opposite side of the body is a sl1ding arm 35, supported on the side rail 4', havmg connection with lever 36 which is connected to sleeve 13, for moving the clutch faces 18 and 17 out of operation. The end 37 of arm extends upwardly to engage the other end of the movable bottom 5 for automatically operating the sleeve 13.

A lever is pivoted to the frame of the body. the lower end thereof being connected with the collar 39 and it will be seen that, by movement of said lever 38, the clutch faces may be moved into cotiperative relation with each other, for setting the machine in operation.

In operation, the bottom 5 having been moved to the position indicated by Fig. 7, the engine is started and clutch faces 19 and 20 brought into cooperative relation with each other. The shaft 14 is accordingly rotated with the result that rotary movement is transmitted to the drum 11 and the bottom is moved in the direction of the arrow in Fig. 4, the load being distributed, and the rear end of the bottom 5 is moved forward and engages lever 33, with the result that the clutch members 12 and 26 are moved out of engagement and serving to stop the movement of the bottom 'in one directlon. In order that the bottom 5 may be returned to its normal position, the clutch faces 13 and 17 are moved into operative relation with the result that the bottom is moved to the position shown in Fig. 6 and it follows that, when the forward end of the bottom reaches its limit, the same engages the lever 35 and clutch faces 13 and 17 are disconnected and the movement imparted to the drum will be reversed.

What I claim to be new is A manure spreader comprising a frame, a flexible bottom, rollers over which the floor travels, a driving shaft, sprocket wheels fixed thereto, a second rotatable shaft, sprocketwheels journaled thereon and each having clutch teeth at their inner ends, sprocket chain connections between the wheels upon the two shafts, a drum splined to said second referred to shaft and havin clutch teeth upon projecting ends thereof, a cable fastened to the ends of the flexible floor and winding about said drum, a pivotal clutch throwing lever, a collar swiveled to the drum and pivoted to said lever, pivoted angled levers having fork ends engaging annular grooves formed in projecting portions of the drum, sliding bars pivotally connected to said angled levers and having bent portions so positioned that the ends of the flexible floor will contact therewith when moving in opposite directions, whereby the drum may be moved longitudinally to engage or disengage the clutch teeth on said sprocket wheels, as set forth.

In testimony whereof I hereunto afiix my signature in presence of two witnesses.

ARTHUR LEWRAY HEWITT.
