MANURE-LOADEB.

Messes.

Application filed May 2?, 1914.

To all whom t may concern:

Be it known that l, llVnnnnn L. VVIRSING, a citizen of the United States, residing at Stuttgart, in the county of Arkansas and State of Arkansas, have invented certain new and useful Improvements in Manure- Loaders, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to manure loaders.

The object of the invention is to provide a thoroughly practical and highly efficient apparatus of this character which will move manure from a pile and discharge it into a wagon or onto any desired site, the manner in which the parts are constructet and coperate being such as to secure the highest efliciency in use with the minimum output of power, and with practically no 4danger of the mechanism becoming deranged from long-continued use.

llVith the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts of a manure loader, as will be hereinafter fully described and claimed.

ln the accompanying' drawings, forming a part of this specification, and in which like characters of reference designate corresponding parts: Figure 1. is a side elevational view of a manure loader constructed in accordance with an embodiment of my invention; Fig. 2 is a top plan View of the device as ierein disclosed; Fig. 3 is a sectional view taken substantially on the line 33 of Fig. 2; Fig. 4L is a sectional view taken substantially on the line of Fig. 3; Fig. 5 is an enlarged sectional view taken substantially on the line 5--5 of Fig. 1; Fig. 6 is an enlarged sectional view taken substantially on the line 6-6 of Fig. 1; l? 7 is an enlarged sectional view taken substantially on the line 7 7 of Fig. 2; Fig. 8 is a sectional view taken substantially on the line S--S of Fig. 7; Fig. 9 is a sectional view taken substantially on the line 9-9 of Fig. 7; Fig. 10 is an enlarged fragmentary elevational View of the reversing mechanism herein ineluded; Fig. 11 is an enlarged sectional View taken substantially on the line 11-11 of Fig. 2; and Fig. 12 is a detailed sectional View of the scoop locking means herein ineluded..

Referring to the drawings, 1 designates a platform upon which the mechanism is supL Specification of Letters Patent.

Serial No. 841,321.

ported. rlfhis platform is carried by a wheeled frame of any preferred construction, the rear Wheels of which will, by preference, be power driven, thus to dispense with the use of horses in drawing the machine over the ground.

Arranged on the platform is a scoop 2, the front end of which is open, and the sides and rear end of which are closed. The under edges of the sides 3 of the scoop are formed with inturned guides 4, which are engaged by a .sliding bottom 5, a cross brace G secured to the bottom and overlapping the guides at its ends, serving to prevent the bottom from rising. The rear wall 7 of the scoop is provided with a series of orifices in which are disposed the shanks of rakes S, which are of the usual or any preferred construction, and of which, in the present instance, siX are Shown. The forward ends of these rakes are secured by a six-throw crank shaft 9, the cranks of which are so arranged that when three of the rakes are raised to take a fresh purchase on the manure the other three are lowered so as to draw the manure on to the bottom. @ne end of the crank shaft is journaled Fig. 3 in a bearing 10 adjustably secured to one of the sides 3, while the other end is journaled in a similar bearing 11 and projects beyond the saine and has secured to it a sprocket wheel 12. The sprocket wheel is engaged bya sprocket chain 13 which passes rearwardly, and diagonally across the platform and engages a sprocket wheel 1d carried by a shaft l5 journaled in a bearing 16 slidably mounted upon the base. rThis bearing 16 comprises two standards 17 carried by a base 18, projected from the front and rear of which are lateral arms 19 that engage guides 2O secured to the platform. One of the standards'has connected with it one end of a rod 2l, the other end of which is connected w'th a crank shaft 22 secured to the rear end of the platform, and which, upon being manipulated, will impart a reciprocatory motion to the standards, thus to move gear wheel Q3 carried by the shaft l5 into and out of engagement with a pinion 2f journaled upon a standard 25 secured to the platform.

ligidly secured at the forward ends of the sides of the scoop or bucket adjacent to their rear ends .are three arms 2G, 27, and 28, the arm 27 being secured to the right hand side of the scoop, when the latter is viewed from the front of the machine, and the other two arms secured to the left hand side of the scoop. rlhe rear ends of these arms are rigidly bolted to one leaf of a hinge 29, the

other leaf of which is rigid with a worin wheel or table 3() carried by 'the lower end of a vertical shaft 3l, mounted in the bearing 32 at the base of the frame, the upper end of the shaft being` mounted in a bearing formed in a bracke'` carried by a standard 311 rising from one side of the platform. The worm wheel engages a worm 35 carried by a shaft 36 mounted in earinos 37 rigid to the platform, and on the shaft 36 is a sprocket 'wheel 3S that is engaged by a sprocket chain that passes around a sprocket wheel #l0 carried by a rock shaft Lil loosely mounted in a standard l2 secured to the platform.

Secured to the rear portion of the platform, and adjacent each side thereof, are two brackets i3 and Lief carrying bearings ll5 in which is ournaled a main drive shaft etti, that is driven from any suitable source of power, such as a gasolene engine or the like. Carried by the shaft -G is a gear 47 which meshes with the pinion 2li and thereby drives the latter to cause it to actuate the gear 23 and thus the sprocket chain 13, the motion of the latter being transmitted to the six throw crank shaft 9, whereupon the rakes will have imparted to them a reciprocatory motion, thus to cause them to grasp the manure and draw it onto the bottom of the scoop. Eis stated, the sprocket chain 13 extends diagonally across the platform, and in order to cause it to remain in operative engagement with the two sprocket wheels 12 and 38 a series of guides i8 are employed which are secured to the shaft 3l, arm Q8 and the scoop 2. rfhis means of guiding the sprocket chain 18 will be found eliicient for the purpose designed, but as will be understood, any other arrangement to secure the same result may be adopted without departing from the spirit of the invention.

The main drive shaft carries two spaced gears 49, which, in conjunction with the gear 50 carried by the rock shaft lll, constitutes adiiferential gear for reversing the direction of rotation of the worin shaft 36 so as to drive the worm wheel 30 in opposite directions, and thus cause the scoop to swing through the arc of a circle in order to distribute the manure properly over the receptacle to receive it.

Secured to the rear end of the bottom 5 is a cable 5l the lower lead of which passes to the rear end of the machine and around a drum shaft 52, the upper lead of the cable being passed around a sheave 53 carried by a link 54 pivotally connected with the rear wall of the scoop, and thence to a drum shaft 55 at the rear end of the machine. One end of each of these shafts is journaled in suitable bearings formed in the bracket 411, the other end of the shafts being arranged for sliding movement in slotted bearings 56 and 57`for'med in a plate 58 supported by a bracket 59 rigidly secured to the platform. The drum shaft 52 carries a pinion 50, and the drum shaft 55 a similar' pinion (3l, and these are engaged alternately to be brought into engagement with a gear G2 on the main drive shaft, the shifting of the drum shaft 52 to bring its pinion into mesh with the gear G2 being accomplished by a lever 63 pivoted to the plate, and connected by a rod G-l with the shaft. lThe drum shaft 55 is moved to and from the gear (S2 by a lever G5 carried by an arm G5 secured to the plate 58, and connected with the shaft by a rod 67. From this arrangement it will be seen that when the pinion on the drum shaft is in engagement with the gear G2, the upper lead of the cable will be wound upon the shaft and thus project the bottom of the scoop, and upon releasing the pinion and locking the pinion 50 into engagement with the gear, the bottom of the scoop will be moved rearwardly, thus to` discharge its load.

As is common with apparatus of this character, means is provided whereby when the scoop has been filled with manure or other material, it shall be raised and held in lifted position until it has reached the point where the contents are to he discharged, whereupon the scoop is dropped and the bottom retracted for that purpose.

rlfhe m ans for causing the raising of the scoop comprises a drum shaft 68 one end of which is journaled in a bearing 69 carried by the bracket 43, and the other end of which is pivoted in a rock arm 70 carried by a bracket 7l supported by the platform. The bracket is provided at its upper end with rack teeth 7 2 that are designed to be engaged by a spring pressed latch 73 carried by the rocking lever whereby a pinion 7% carried by the drum shaft 68 may be moved into or out of locking engagement with the gear h17 of the drive shaft.

rEhe rear end of the scoop has secured to it one end of a bar 75, the other end of which has connected with it a sheave 75, and through this sheave passes a cable 77 which is secured at one end to the standard Se, and the other end tothe drum shaft 58. V"it will be seen that when the rock arm 70 is moved to lock the ainion 7e into engagement with the gear ai', that a backward pull will be imparted to the cable 77, thereby lifting the scoop, and upon the pinion being disengaged the scoop will of its own weight drop into its original position, whereupon the mechanism for actuating the bottom may be manipulated to cause the load on the scoop to be discharged.

In order to maintain the scoop 2 in elevated position after the drum shaft 68 has been disconnected from the gear 47 of the drive shaft, l employ the clamping member 7S pivotally supported between the npstanding spaced ears of a bracket 79 suitably secured to the upper surface ot' the bracket 33, the cable 77 passing' between the ears of the bracket 79 and below the clamping member 7S. The clamp 7S is operated in a manner which is believed to be selfeevident.

From the foregoing description, it is thought to be obvious that a loader constructed in accordance with my invention is oit an extremely simple and comparatively inexpensive nature and is particularly well adaptedfor use by reason or the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modilication without material departure from the particulars and spirit thereof and for which reason l do not wish to be understood as limiting myselic to the precise arrangement and formation of the several parts herein shown in carrying' out my invention in practice.

`What l claim and desire to secure by Letters Patent is l. A device of the character described comprising, a frame, a scoop supported thereby and mounted for movement in a vertical direction and in a horizontal direction, a movable bottom for said scoop, a flexible member secured intermediate its length to the movable bottom and loosely engaged with the Scoop at substantially a stationary point, and means coacting with the liexible member at points opposite to its connection with the movable bottom for imparting reverse movement to said liexible connection whereby the movable bottom may be adjusted into either a closed or open position.

2. A device of the character described comprising a frame, a scoop supported thereby for movement in a vertical direction and in a horizontal direction, a crank shaft disposed transversely of the scoop above the bottom thereof, rakes disposed longitudinally of the scoop and operatively engaged with the crankshaft, a source ot' power fixed relative to the frame, a flexible connection between the crank shaft and the source of power whereby said crank shaft may be rotated irrespective of the vertical or horizontal adjustment of the scoop, a guide for the flexible member carried by the scoop at a point rearwardly of the crank shaft, and a second guide for the flexible member carried by the frame and positioned at substantially the axial center of the horizontal movement of the scoop.

ln testimony whereof l hereunto al'liX my signature in the presence of two witnesses.
