To all wtom z' may concern.'

Be it known that I, HANS H. PnTEnsEN, a citizen of the United States, residing at Correctionville, in the county of Voodbury and State of Iowa, have invented certain new and useful Improvements in Loaders, of which the following is a specification.

This invention relates to means for transferring manure from a barn yard to a wagon for transportation to a field which is to be fertilized and the object of the invention is to provide a strong, compact, simply constructed and easily operated mechanism which will efciently load the manure into the waiting conveyance.

The invention is illustrated'in the accompanying drawings and will be hereinafter fully set forth.

In the drawings- Figure 1 is a view partly in side elevation and partly in longitudinal section of a loader embodying my improvements;

Fig. 2 is a detail plan view of a part of the operating mechanism;

Fig. 3 is a plan view of the loader;

Fig. 4 is an endelevation of the'loader;

Fig. 5 is a detail transverse section on the line 5 5 of Fig. 1.

F ig. 6 is a detail elevation of the upper end of the'conveyer, viewed from the side opposite that seen in Figure 1.

v In carrying out my invention, I employ a base or main frame comprising sills 1 which may be of any substantial form and are connected at one end by an end plate 2 and near their opposite ends by transverse beams 3. vThe said beams 3 project beyond one sill 1 and the extended ends of the beams are connected by a bar 4. The driving mechanism is supported upon these beams 3 and bar 4 as will be presently more fully set forth. Upon the sills 1, I secure an upper frame consisting of side bars 6 whichv eX- tend from that end of the base at which the plate 2 is located to a point adjacent the4 center of the base and serve to support platforms 7 which bridge the said side bars, as

fclearly shown. These platforms are separated or spaced apart longitudinally of the side bars so as to provide a feed opening 8 through which the manure may be deposited upon the conveyer, and restingagainst the side bars are inclined kways 9 up which a scoop may be drawn so as to discharge through the opening or space 8 as will be readily understood. lIt will also be undercliains or cables -will be attached to the same and extended across the base frame to be coupled to draft animals so that the scoop kwill be readily drawn'up theway 9 at one stood that when scoops are employed draft side of the platform and discharged onto the conveyer. It may sometimes be convenient and more desirable to load the fertilizer onto the conveyer by merely shoveling 'or pitching it through the opening 8. l

I/Vhere the accumulation of manure is eXtensive, it is possible to locate the base or main frame immediately adjacent the pile of material- `which may then be quickly fed through the opening 8 by the use of' pitch forks or shovels as is obvious. It may somei times also be more convenient and economical to feed the material onto the conveyer by the use ofbarrows or similar receptacles which may be readily moved up the inclined ways 9. It will thus be kseen that Ido not limit myself to any particular manner of delivering the material into theloader and it is also to -be understood that while the apparatus is intended primarily for loading manure into farm wagons, as previously stated, it may be advantageously used for handling other materials. It is also to be understood that the apparatus may be employed in connection with a portable engine to yspread `over a vfield fertilizer delivered onto'the conveyer by wagons. y

i Adjacent the inner ends of the side bars 6, inclined vside bars 10 are secured upon the sills 1 and the upper ends of these side bars are supported and braced by standards 11` rising from the ksills or from the beams 3 as may be most convenient andas will be readily understood. Extending along the inner sides of thebars 10 and the sills 1 are strips 12 on, which are mounted rollers 13 to support the conveyer consisting of 'transverse bars or slats 14 connected by parallel `by a drum or roller 17 mounted in and extending between the sills 1 immediately adjacent the end plate 2 and a second drum or roller carried by a shaft 18 mounted in suitable bearings at the upper ends of the inclined side bars 10. A supporting roller or drum 19 may be mounted upon the braces 11 to support the under run of 'the conveyer and prevent excessive sagging of' the same.

Upon one end of the shaft 18, 1 secure a. sprocket 20 around which is trained a chain 21 which also passes around a sprocket 22 upon a shaft which is mounted upon the frame provided by the beams 3 and the bar 4;. rlhe sprocket 22 is loose upon the shaft and a bea-ring` sleeve 2a is fitted upon the said shaft inwardly from the sprocket and supports the inner end of a driving shaft 25 which extends forwardly and is journaled upon the outer beam 3, the outer or forward end of the said shaft carrying a band pulley' or driving gear wheel 26 to which power is applied from any convenient or preferred motor. 1t will, of course, be understood that power may be applied directly to the shaft 23 and the band pulley or wheel 26 utilized as a fly wheel, and it will also be understood that instead of a mechanical motor the power may be derived from a draft animal driven source. Upon the shaft 25, a pinion 27 is adjustably, secured and adapted to mesh with a gear 23 which is keyed to the shaft 23, as indicated at 29. The pinion 27 may be adjusted longitudinally of the shaft 25 and radially of the gear 28 so that the speed of rotation ofthe shaft 23 may be varied to suit the requirements of 'any particular work and the pinion 27 will be secured in a set posi- .tion by a set screw mounted in its hub and bea-ring upon the shaft 25 as will be readily understood. The gear 28 may be a multiple gear or may be one of a plurality of interchangeable gears of various diameters. T he hub of the sprocket 22 is provided with an annular groove, as indicated, and this groove is engaged by a pin or roller upon a lever 31 which is fulcrumed upon the .front beam 3 and is provided with a latch 32 adapted to engage a rack 33 on the beam so that the lever will be held in a set position. The hub is adapted to engage a clutch. collar 3() secured to the shaft 23 so that it may be thrown into or out of gear as is obvious.

In the use ofthe device, the pinion 27 is adjusted relative to the gear 28 so that the conveyer will be driven at the desired speed and the material to be loaded is fed continuously through the feed opening 8 so as to drop directly onto the conveyer which will carry it up and over the wagon stationed under the high end of the conveyer so that as the conveyer passes around the upper drum or roller the material will be discharged into the wagon. Vhen one wagon has been loaded, it is not necessary Laeaaia to stop the engine while another wagon. is being' brought into position to be loaded 1nasmuch as shifting of the lever 31 will quickly disengage the membersof the driving gearing and thereby stop the travel. of the conveyer. llfeai" upon the parts of the conveyer will thus be avoided while the time required to drive a loaded wagon ont of position and to bring an unloaded wagon into position to be loaded is so short that there would be no economy in stopping the engine. lt will be readily noted that the driving gearing is all located below the conveyer and under the inclined portion of the same so that the conveyer will serve as a cover for the driving gearing to prevent clicking of the same by the material being handled. The apparatus is exceedingly simple in the construction and arrangement of its parts and may be easily operated. The parts are eompactly arranged so that they are not apt to get out of order and they may be manufactured at a low cost. lt will be noted that my ,apparatus operates. con-- tinuously so that the material to be loaded will be supplied to the wagon in a continuous stream and it is not necessary to intermittently or periodically .stop the operation to permit a sufiicient depositto be placed upon the conveyer. 1t will also be noted that the platforms 7 upon the base cover the lower conveyer supporting drum or roller and also cover the guide rollers 16 so that the material .fed onto the conveyer cannot drop upon these elements and chokethe operation of the same.

The driving chain 21 passes over an idler 3a which is carried by a bracket 35 adjustyably secured to the adjacent standard 11 whereby the chain is supported against and held out of the way of vehicles driving under the delivery end of the conveyer. The chain may also by this device be kept under the proper working tension.

lilounted for pivotal n'ioven'ient about the .sha ft 18, at the outer sides of the side bars 10, are arms 36 and journaled in the lower ends of these arms beyond the side bars is a spreader shaft 37. Blades 38 radiate from the spreader .shaft and extend along the same between the arms 36 so that when the spreader is properly adjusted, the material discharging over the upper end of the conveyer will be received by the revolving blades and by them will be thrown forward from the conveyer a greater or less distance according` to the adjustment of the spreader arms 36. To rotate the spreader shaft, a sprocket pinion 39 is secured on the shaft and a chain 4.0 is trained around the same and a. sprocket gear L.l1 on the shaft 18, the described gearing being located at that side of the apparatus remote from the sprocket 20. To adjust the arms 36 out of the path of the material. or more or less into said path, I provide a hand lever 42 which is fulcrumed upon a side bar l0 and to which is pivoted a bail 43, the side members of the bail extending through clips 44 on the arms 36. The weight of the spreader blades and shaft with the sprocket 39 tends to hold the arms in a vertical position with the spreader below the oonveyer out of the path of the material. By swinging the lever 42 rearwardly, however, the engagement of the sides of the bail with the ends of the clips will cause the arms 36 to swin toward a position in alinementwith the side` bars l() so that the spreader blades swill act on the material and throw it forward in the wagon or other conveyance. I am thus enabled to distribute the load evenly in the wagon.

Having thus described the invention, what is claimed as new is: y l l. In a loader, the combination of a conveyer having an inclined portion, spreader arms pivotally mounted at the upper end of the inclined portion of the conveyer, a

spreader shaft mounted in the outer ends of said arms, radial blades extending along the shaft between the arms, means for rotating the shaft, and means for pivotally adjusting the arms, the arms being normally so disposed that the spreader shaft is below the end of the conveyer.

2. In a loader, the combination of a conveyer having an inclined portion, spreader arms pivotally mounted at the upper eX- tremity of the inclined portion of the conveyer, a spreader carried by the ends of said arms and thereby disposed beyond the end of the conveyer, means for operating the conveyer and simultaneously operating the spreader, clips on the sides of the spreader arms at the kends thereof remote from the spreader, a kbail bridging the spreader arms and engaging said clips, and an adjusting lever mounted upon the conveyer and pvotally connected with said bail.

In testimon whereof I ax my signature. 45
