ERNEST CAIETSKE, OF EAST GRAND FORKS, MINNESOTA.

MANURE-LOADER.

To all fio/0m t may concern:

Be it known that I, EnNns'r Carrrsin, a citizen of United States, residing at East Grand Forks, in the county of Polk and State of Minnesota, have invented certain new and useful Improvements in Manure- Loaders; and I do hereby declare the following 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.

This invention relates to a device for loading various types of material, such as manure, straw or the like, from a pile or stack upon a wagon, and the primary object of the invention is to employ in a loader structure, a carrier or conveyer, a pivoted scoop positioned at the lower receiving end of the conveyer and a plurality of forks which are carried by arms that are in turn supported by a rotatable crank shaft for moving the arms in substantially oval paths to carry the material from the scoop upon the conveyer and further to provide a supporting structure for the carrier fork which is pivotally mounted and controlled by the pivotal operation of a lever, so that the distance between the upper surface of the scoop and tines of the fork may be regulated, as made necessary.

With the foregoing and other objects in view this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters designate like and corresponding parts throughout the several views, and in which:

Figure l is a side elevation of the improved loader,

ll'ig. 2 is atop plan view of the loader,

Fig. 3 is a vertical longitudinal section through the loader,

Fig. 4 is a fragmentary horizontal section through the loader, and

Fig. 5 is a section of the line 5 5 of Fig. 1.

Referring more particularly to the drawings, 1 indicates the supporting frame of the loader, which is supported by suitable axle structures 2, upon which are mounted supporting wheels 3. The axles 2 and supporting wheels 3 are provided for permitting Specification of Letters Patent. Patnted lua 22 1921.

the loader to be transported from one place to another.

r'ipair of inclined side boards 4 are rigidly carried by the supporting structure l and they support rollers 5 and (5 at their lower and upper ends respectively, over which rollers an endless conveyer 7 travels. The endless conveyer 7` is constructed in any ordinary manner and it projects beyond the rear end of the supporting frame for delivering material to a wagon. The upper run S of the conveyer travels upwardly over a supporting and guiding board or platform 9 which prevents the sagging of the upper run of the conveyer during its load arrying movement.

The lower roller 5 is carried by a shaft 10 upon one end of which is mounted a power pulleyll. Any suitable power producing and transmitting means may be connected to the pulley 11 for rotating the shaft 10 and operating the endless conveyer. The shaft 1() has a second pulley 12 mounted upon its end remote from the pulley 11 and a belt'13 passes about the pnlley 12 and about a pulley 14 which is mounted upon a crank shaft 15.

The crank shaft 15 is rotatably supported by suitable bearings 16 that are carried by a pivotally mounted super supporting structure 17. The standards 19 are connected to the standards 21 of the supporting structurel by braces 22 which are pivotally connected to the standards 19 and 21. A link 23 is pivotally connected to one of the standards 19 near .its lower end, and it is connected as shown at 24 to a hand lever 25. The hand lever 25 is pivotally connected as shown at 26, to the supporting frame `1 so that upon pivotal movement of the handlever 25, the super supporting frame 17 may be moved upon its pivot upon the shaft 19. Suitable means indicated at 27 is provided for holding the lever 25 in various adjusted positions.

A. shaft 2S is carried by the standards 19 and it has a pair of arms 30 connected thereto, which arms are held in proper position upon the shaft by suitable spacing collars 31. The arms 30 have their free ends pivotally connected as shown at 32 to arms 33 which arms are in turn connected to the wrist portions 34.- of the crank shaft 15 by suitable bearings 35. Forks 36 are carried by the free ends of the arms 33 and they are braced by suitable vbraces 37. The

forks 3G are positioned vertically and have their tines extending downwardly toward the conveyer structure 7 and during the rotationV of the crank shaft 15, through the medium of the pulleys 12 and 14 and the belt 13, the forks will be guidedcand caused to travel in a substantially oval path, a portion of their upward movement being in close proximity to the conveyer 7 and to the scoop 38 for carryingmanure, straw or other analogous material from the scoop upon the conveyer for delivery into a wagon.

The scoop 38 is constructed of suitable cheap metal and it has its front end and its side upturned as shown at 39. The front end of the scoop 38 is upturned so that it may be embedded ina manure or straw pile. VThe scoop v38 is attached to a bar 40, which bar is pivotally supported as shown at 41 to allow the Vscoop to be swung pivotally for varying the incline thereof. Tongues 42 are struck out from the bottom of the scoop and they extend upwardly and over the forward edges of the side boards 4 for preventing material from passing downwardly through the opening in the scoop bottom which receives the forward lower ends of the side boards 4 of the conveyer supporting structure. An arm 43 is connected to the scoop 38 and has its rear end portions extending through U-.shaped brackets 44 securedto the frame 17. Lugs 45 are arranged on the arms and are adapted for engaging the brackets 44 to retain the scoop in an adjusted position. Y Y

Summing up; the operation of the improved loader is'minutely as follows; the

loader is placed to a pile of manure, or stack of straw Vso that the scoop 38 will engage the stack of material and the shaft 1.0 is rotated by any suitable means for operating the conveyer 7 and also for rotating` the crank shaft 1-5 which will cause the carrier forks 36 to move in substantially elliptical paths over the scoop 38 and the conveyer 7, causing the forks on their upward rearward movemen-t to engage portions of the material and carry it over the scoop 38 for delivery to the conveyer 7 which conveyer delivers the material to a wagon or any other suitable device. If the materialis. light, such as straw, the lever 25 is operated for tilting the frame 17 to cause the forks to travel at their maximum distance above the scoop and conveyer but if the material is heavy and only a relatively small quantity of the same is engaged by the scoop, the lever Q5 is rocked for rocking the frame 17 to lower the forward end of the frame and cause the carrier forks 36 to travel at their minimum distance from the scoop 38 and conveyer 7 for elliciently engaging the material and carrying it to the elevator or conveyer structure 7.

In reducing the invention to practice, certain minor features of construction, combination and arrangement of parts may necessitate alterations to which the patentee is entitled provided such alterations are comprehended within the scope of what is claimed.

What is claimed is:

A loader including a portable structure having vertical uprights, an inclined conveyer frame secured to the uprights and the portable structure, an endless conveyer carried by the frame, a power shaft for the conveyer, a. scoop associated with the lower end of the conveyer, a supporting structure including pairs of connected uprights and one pair of said uprights pivotally supported by the power shaft, forks carried by said support, means for operating the forks by the power shaft, braces pivoted to the other pair of uprights and to the upper ends of the first mentioned uprights, a lever pivoted to one of the first mentioned. uprights, and a link connecting the lever to one of the uprights of the last named pair for rocking the support to move the forks toward and from the scoop and the conveyer.

In testimony whereof l ailix my signature in presence of two.\vitnesses.

ERNEST CAPITSKE.
