Application filed September 25, 1908. Serial No. 454,715.

f0 all whom it may concern:

3e it known that l. Delmar Gamer, a citizen of the l nited States of America, residing at \Vaterloo. in the county of Blackluuvk and State of Iowa, have invented certain new and useful Improvements in Manure- Spreaders. of which the following is a specification. reference. being had therein to the znwonnianying drawings. 1

Ordinarily, in the construction of manure spreaders, it is usual to have the discharge end or opening of the carrying body or reeeptaele either at the lower end or otherwise, so disposed that the contents tends to-fall toward the opening. and thereby to pack, cake or settle around it, so that any distributing or delivering means used to positively feed the material through or out. of the opening is obliged to work up this packed mass. This also renders accurate regulation of the rate of delivery difficult and increases the work to be done by the distributing mechanism. Y

This invention relates to a manure syn'eader wherein the load cannot become clogged around the delivery mouth and wherein there is a positive discharge which may be easily regulated by the operator.

Another object of the invention is to pr vide simple and effective means for throwing. the distributing mechanism in or out of gear. and to arrange the parts to work smoothly so that any back lash or the like which may occur, will notcanse intermittent delivery.

The invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a view in side elevation of a machine embodying features of the invention. Fig. 2 is a View in section on line a:m of Fig. 1, parts being omitted. Fig. 3 1s a plan .view, partially broken away,

of the machine.

Referring to the drawings, a pair of traction or driving bearing wheels 1 are journaled on the rear axle 2 secured by the usual means as clips 3 to bolsters 4c and 5. Longitudinal body sills 6 are supported near their rear ends at an interval above the upper bolster 5 by suitablydesigned brackets 7 or the like and are carried near their forward ends by similar brackets 9 above standard bolster and king bolt. connections indicated at t) of front. earing wheels 10 of less diamand chain 35.

that the sills are inclined. ,lottom boards 11. stanchions 12 on the ends of erosssills or bars 13, side boards ll and a front board all of conventional, standard construction, complete the main body.

' A drive shaft 15 is journaled in suitable hearings on the underside of the main sills near the rear end of the body, and a pair of sprockets 16 are keyed or otherwise secured .on the ends. A pair of rigid radius'rods 1i are-pivoted at the rear ends to the drive shaft and at their forward ends to links '18 which articulate them to the ends of rock arms 12) ofa rock shaft 20, which turns in bearings 21 on the main sills (3. A lever 22. rod 23 and throw out latch lever 2t engaging a quadrant 25 near the operators seat, or other convenient ,means are provided for rocking the shaft 20 and consequently raising and lowering the radius rods. An idler sprocket- 26 journaled on a stud 27 at the front. end of each radius rod and a sprocket drive chain 28 connects each idler with the alined drive sprocket 16. A main sprocket; 29 is -journaled-on the rear axle 2 adjacent each traction wheel 1 with a ratchet wheel' and pawl connection 30 of any suitable design whereby forward 'rotation of either traction wheel turns the companion sprocket. The drive chains 28 are disposed in the planes of the main sprockets so as to be thrown in or out of mesh with them by proper manipulation of'the rock shaft and its operating means.

A beater roller 31 journaled in bearing brackets 32 at. an interval above the rain end of the body bottom boards 11, operatively connected to the drive shaft 15 by; any suitable means, as sprockets 33 and 34.

In preferred form the periphery of the roller 31 is built. up of spaced bars 36 with pickers or teeth 37 extending th erefrom An endless conveycr flight. traverses the bottom of the body longitinlinally, and preferably consists of transverse spaced bars or slots 38 on sprocket chains 39 traveling over idlers 40 on an idler shaft ill near the front end of the main sills (t and drive sprockets "t2 on the drive shaft 43 journaled on the main sills at their upper rear ends below the beater roller. The drive shaft is operated by the traction wheels through any suitable connection. As herein shown as a preferred eter than the' driving or traction wheels so form, a transverse shaft 44. connected through a bevel gear train with the bea er shall, has a worm 46 on its lower end, adapted to mesh with a worm gear 47 keyed or otherwise made fast on the conveyer shaft -13. Guide boards 49 on the bolster 5 and false or sub-sills 50 may he used if desired, to house the lower limb of the conveyor iiighi. 'lhus the bottom of the body is, in cilia-i, an inclined conveyor adapted to carry material from the lower end to the upper ilisclzargc end.

f1 iail board 51 is raised or lowered over the ronveyer flight al the upper or discharge end of the body inside the beater oller, by on ans of a rock shaft :32 with arms 53 having slots 5% engaging pins 53 on the board, and a lcrer so connected by a link 57 to the lalrh lover near the operai'ons seat which llirwvs lhe mechanism in and out of gear, the arls being so disposed (hat the gate is raised when ihe lever is thrown in.

llbviously, any form oi compensating lranwniseion mechanism between the traction wheels and the conveyor flight: and beaier may be used, if i'leeircd, also the front end of the body may be lligbl and its mechanism reversed so as to discharge in front, ii n'eierrcd.

()ne of the advantages of this a'rrai'igcna-nl lies in ihe fact that the load, which i usually placed in the body and drawn HOMO distance to the place of one, does not settle againsl but away from lhc discharge end. Thie {)(llllllFf the raising of the tail board without any prying or hammering to looeen ii. a1 also allows the carrier to work freely. an ;-i does not travel into but away from ihai portion of the ioazl which tend to pack and become (salted or matted. oilier feaiure is (he reverse direction of roiaiion oi the beater againel' the conveyor, ll 'l: picks and dir-zimegrates any lumps or in and evenly furl her advantage is he disposition oi the niveyer flight whereby elevated, and he Anl the loaded limb is I the wheels to the beater always taut and therefore does not feed the inaterial against the beater irregularly.

Obviously, changes in the details of construction may be made without departing from the spirit of the invention, and I do not care to limit myself to any particular l'orni or arrangement of parts.

\Vhat: I claim as my invention is:

1. The con'ibination in a manure spreader, of a body, traction bearing wheels supporting the body, a healer at the discharge end oflhc body. a conveyor secured permanently in an inclined posiiion and adapted to move ihc contents of the body upwardly toward the bMCI', and driving means connecting and the conveyor, the inclination of the conveyor being only sullicient to take up lost motion in the driving means when the eonvoyer is loaded.

2. A manure spreader comprising a body,v

an inclined endless conveyor flight traversing the body longiiuilinally adapted to carry unilerial lo its upper end, the inclination of the flight. being only sufficient to hold the loadedliinb iaut, a driving shaft journalcd in ihc body and inieraiively connected to the flight. a sprocket wheel on each end of the driving shalt. a pair of radius rods pivoted at the innercnd on the drive shaft, an idler sprocket wheel pivoted on the outer end of each radius rod, a drive sprocket chain connecting each idler with an adjacent drive shaft aprocli'el'. a'pair of traction bearing wheels for the body, a drive sprocket adjacent each traction wheel in the plane of rol'ation of a drive spn-acket chain, operativcly connected lo the iraciion wheel and means Supporting the outer ends of the radius rods adapted lo more the drive chains in and out oi. mesh with the traction wheel sprockets.

In testimony whereof I afiix my sigi'iature in presence of two witnesseq.
