. MECHANICAL MOVEMENT.

Specification of Letters Patent.

Patented Aug. 13, 1912.

Application filed April 13, 1910. Serial No. 555,185.

To all whom it may concern Be it known that I, VVILLIAM L. KIssEL, a citizen of the United States, residing at Hartford, in the county of Vashington and State of IVisconsin, have invented certain new and useful- Improvements in Mechanical Movements, of which the following is a" specification.

"This invention relates to a mechanical movement which is especially adapted for use upon manure Spreaders. The object of the invention is to provide an improved mecha nism for driving theapron and controlling the rate .of travel thereof.

,In the accompanying drawings, Figure 1 is a. fragmentary side elevation of the rear portion of a manure spreader equipped with an apron-driving mechanism embodyin the features of my invention. Fig. 2 is a tragmental side elevation of said mechanism, detached from the spreader and showing the parts indifferent ositions from those occupied in Fig. 1. ig. 3 is a view similar to Fig. 2 showing the parts in still another position. y

In the embodiment of my invention which I have herein illustrated, the apron (not shown) is suitably arranged to be driven by a shaft '1 rotatably mounted in the rear portion of the spreader box A. Upon one end of the shaft 1 is mounted a' ratchet wheel 2. An arm 3 pivotally mounted upon the shaft 1 adjacent the ratchet wheel 2 carries a pawl 4 arranged to engage the teeth of the ratchet wheel so that pivotal movement of the arm 3 in one direction will rotate said ratchet wheel. A detent 5 mounted, in this instance, upon a suitable part of the box A is adapted to engage the verse movement of said ratchet wheel.

teeth of the ratchet wheel 2 to preven(t3 reisa coiled spring having its ends connected to the pawl 4 and the detent 5 and serv1ng to hold said pawl and said detent 1n engagement with the ratchet wheel 2. The spring 6 also tends to draw the arm 3 forwardly, the pawl 4 in this movement of said arm riding over the teeth of the ratchet wheel 2.

The means for swinging the arm 3 rearwardly thereby rotating the ratchet Wheel '2 through the medium of the pawl 4, comprises an eccentric 7 mounted upon one end of the beater shaft. A rod 9, having at one enda strap 10 surrounding the eccentrlc 7, extends slidably through the eye 11 carried by the arm 3. A coiled spring 12, surroundmg the rod 9, is adapted to hear at one end against the eye 11 and at its other end against a" pin 13 or other suitable stop fixed to the rod 5), said spring serving as a buffer for cushioning the engagement of the rod 9 with the arm 3 when said rod is reciprocated rearwardly by the eccentric 7.

The heater shaft 8, carrying the usual drum 14 and teeth 15, may be driven by any common or preferred means. I have deemed it unnecessary to illustrate any driving means for said heater shaft. I

I have provided means for limiting the oscillatory movement of the arm 3 so that the pawl 1 carried by said arm will travel over a greater or lesser number of teeth of the ratchet wheel 2, and thereby move said ratchet wheel, and the apron driven thereby, through a greater or less space at each oscillation of said arm 3. Said means as herein shown comprises a rod 16 slidably mounted in an eye 17 on the spreader box, the rear end of said rod passing loosely through an elongated opening 18 in the upper end of the arm 3. A collar 19 is secured on the rod 16 rearwardly of the eye 17 and a coiled buffer spring 20 is pos .ioned on said rod between said collar and the rear end. of the rod. The rod 16 is arranged to he slid longitudinally by any suitable means, as, for example, a hand level-'21 pivotally mounted upon the spreader box near the drivers seat-, said hand lever being connected to the forward end of the rod 16. It will be seen that when the rod 16 is moved rearwardly, as shown in Fig. 3, the forward movement of the arm 3, which is caused by the spring 6, will be yieldingly limited by the engagement of said arm with the coiled spring 20 upon the rod 16. When the forward movement of the arm 3 is thus limited, there will be a slight amount of lost motion. between the buffer spring 12 upon the eccentric rod -9 and the eye 11 upon the arm 3. The rearward movement of said rod 9 will therefore be effective in oscillating the arm 3 through a distance less than its full arc of oscillation, and the apron will consequently be moved through a smaller distance at each revolution of the beater shaft 8.

It will be understood that a suitable lock e. 9., the conventional and well known pawl and sector device commonly employed for locking hand levers, may provided for the hand lever 21, so that the rod 16 may be fixed-in any desired' position; according to the rate at which theoperator desires the apron to move.
