To all whom 'it may concern:l

Be it known that I, AXEL MossBERG, a citizen of the United States, residing at VVestpoi-nt, in the county of Cuming, of Nebraska, have invented certain new and useful Improvements in Manure-Spreaders; and I do hereby declare the following to be 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.

This invention relates to combined manure loaders and spreaders and has for an object to provide a tilting box having novel means at the forward end forl adjustably suspending the boxfrom the main frame.

A further object of the invention is to provide a fast drive mechanism for the endless carrier so that the material will be carried from the scoop as fast as taken up `by the latter during the loading operation.

A further object ofthe invention is to provide a novel clutch mechanism for controlling the movement of the endless carrier and spreader cylinder.

With the above objects irrnfiew the invention consists of certain novlfdetails of con struction and oornbination'of parts herein, after fully described and claimed, it being understood that various modifications may be lmade in the minor details of construction within the scope of the appermied claim.

In the accompanying dra"*ng's-forming part of this specificationz-Figure 1 is a' side elevation of -the device with the box 'shown depressed in dotted lines. Fig. 2 is side of the device. Fig. 3 is a plan view of the device. Fig. 4 `is a cross sectional view taken on the line 4-4 Fig. 1. Fig. 5 is a cross sectional view en the line 5 5 Fig. 3. Fig.

actuating cam'nger.

.Referring now to the drawings in which like characters of reference designate similar parts, 10 designates a rear axle which is equipped with ground wheels 11. Spaced channel iron rails 12 are supported at their rear .ends upon the axle through the instrumentality of bearing blocks 13, and are bent inwardly at their forward ends as shown at 14, a swiveled fore-truck 15 being secured to the extreme forward end of the rails. The rails form the mainframe, of the device.

A counter-balanced'box is supported upon the rear axle and comprises parallel chan- State near the opposite end lever 24'. Short links 25 are pivotally s'e.

nel rails 16 which are suspended from the Patented Dec. 10, 1912.

axle through the instrumentality of hangers 17 box sides 18 being secured to the rails through the instrumentality of straps 19 and 20, the sides being provided with suitable. orifices near their rear ends to receive the axle. The box is thus pivotally secured to the axle near the rear end, and by virtue ofthe endless lcarrier and spreader cylinder actuating mechanisms being disposed at the rear end of the box this end isso weighted that the forward endof the box tends to rise above the rails lof the main frame. f

For securing the forward end of the box, pedestals 21 are secured tothe channel bars of the main frame and receive a stationary shaft 22, the shaft being equipped near one end with an upstanding loose crank 23' and with a loose bell crank cured to the bell crank lever and loose link 23 on opposite sides of the shaft, and to the sides of the box rearwardly of the shaft, and suspendthe forward end of the box l'from the shaft. When the bell crank lever .grip`is elevated the forward end of the box is lowered, and

upon release of the bell crank lever the forward end4 tilts back to normal/position, this upward tilting movement being limited by the short link 25 of the loose crank 23 contacting with the shaft as shown.

Secured to the forward ends of the box sides is a scoop 26 which is designed to penetrate andv scoo upl lthe material when the forward end of the" .box is lowered. For conveying the material thus :scooped up rearwardly into th'e box, an endless fabric carrier 27 is trained over rollers 28 and 29 journaled at the forward' and rear ends. of the box channel rails, the ends of the rear roller shaft extending beyond the'rails and being equipped with means for driving the roller aswill be presently described. A spreader cylinder 30 is mounted for rotation lbetween the sid/es at ktlie rier, the shaft equipped at one end with ley 32.

31. of the cylinder, being a driving pulrearend of the endless car- A driving shaft 33 is journaled in beari ings 34 arranged on the box channel rails and is equi ped at its opposite end with gears'35 an 36, a sprocket chain 37 being trained over the gear 35 and over a sprocket gear 38 iixed to the adjacent ground wheel.

The bearing on one side of the box is provided withl a slot 38 to receive the shaft as shown in Fig. 3.

A shift link 39 is pivoted on one of the box channel rails and is equipped with a central opening to receive the shaft near the gear'36 and is furthermore connected to an operating lever 40 through the instrumentality of a link 41. A driven shaft 42 is journaled in suitable bearings on the Kchannel rails adjacent to the driving shaft and is equipped at one end with a gear 43 which is adapted to mesh with the gear 36 when the shifting link is rocked toward the driven shaft. The driven shaft is equipped at the opposite end -with a belt pulley 44 over which and the driving pulley 32 of the spreader cylinder an endless belt 45 is trained. When the-operator moves the lever 40 rearwardly the cylinder will be rotated and will dischargethe material carried back by the endless carrier.

During unloading the endless carrier is driven slowly, and to attain this end a ratchet wheel 46 is fixed to one end of lthe rear roller shaft of the endless carrier, and swivelly mounted on the shaft is a rock link @'47 carrying a gravity pawl 48, the rock link being actuated through the instrumentality of a pitmanl49 carried by the belt pulley 44 of the `driven shaft. The pawl operatively engages the ratchet wheel and advances the vroller shaft step by step during rotation of the said belt pulley. rIfhe pitman is remove ably 'connected to the rock link through the instrumentality of a pintle 50.

The pitman is detached during vthe loading operation to permit of the endless carrier being driven fast as will now be described. Therearroller-'shaft of the endless carrier is equipped remote from the ratchet wheel with, a belt pulley` 51 over whichand a loose clutch pulley 52 carried by the driven lshaft an endless belt 531'is trained; The clutclrpulley52v is equipped with a ratchet face 54 which meshes' with a v similar ratchet face 54 onth'ev gear 43" car` ried by the driven shaft, and a spring. 55

actuated at a comparatively high rate of speed for loading.

Inorder to normally hold the lclutch faces ofthe pulley 52 and gear 43 out of engagement, a link 56 is centrally pivoted on the box `side above t-he gear l43 and is bent lower/end to form cam edge 58. A yoke 59 straddles the When the parts are so engaged the endless carrier will be driven shaft between the clutchV pulley 52 and gear 43 and is adapted to ride out upon they beveled cam edge of the carrri link and move the loose pulley outward'upon the driven shaft against the tensi'bn of its spring and disengage the :cam face of thepulley from the cam face of the gear. `A connecting link GQ is-pivotally connected'tothe ilpper end of the link 53-and extends forwardly along the box side, being terminally connectv ed to an'operati-ng lever 61' through the in` Y' strumentality of which the link 53 may beY f i actuated. 1 What is claimed, is

The combination witha dlrigible frame,

of a counter-balanced box pivoted'near the" means for adrear end on said frame, an

justably securing the-'forward endl ofsaid box to said frame comprisinga shaft carried by said frame, a loose u standing link on said shaft, a bell crank ever on" said shaft, and short links pivotally connected to' said. loose link "and to said bell crank lever on opposite sides of Isaid shaft and pivotr ally connected to saidbox in rear oi'sa'idA shaft. ,In testimony whereof, I --aiix my signa ture, in presence of. two witnesses.
