Application led .Tuly 8, 1919.

To all whom t may concern Be it kno-wn that I, JOHN E. DowDEN, a citizen of the United States, and resident of Lake Preston, in the county of Kingsbury and State of South Dakota, have invented a certain new and useful Loading-Machine, 4of which the following is a specification.

The obj ect of my inventio-n is to provide a loading machine of simple, durable and inex ensive construction.

ore particularly it is my object provide a machine adap-ted to load all kinds of manure; hay or straw from a pile; and loose dirt, sand, or gravel onto a wago-n or other means of co-nveyance.

A further object isl to provide such a machine adapted to be furnished complete except the engine, so that the owner may install any engine which he may desire when the machine is in use, thereby avoiding the additional expense of an engine adapted for this machine only. l

Still a further object is to provide a machine comp-rising an elevator adapted to lift the material to be loaded from the ground and to carry the material to position where it may be dumped upon the conveyance.

Still a further object is to provide in c onnection with the elevator, agitating devices adapted to tear down the material to be loaded from a pile and throw it on the elevator or to position where it may be readily picked up by the elevator.

Still a further object of my invention is to provide means for adjusting the vertical position of the lifting end of the conveyer and the agitating devices, whereby the conveyer may be regulated to remove the material to be loaded from uneven ground, and whereby the agitating devices may tear down material from the top of the pile as well as the bottom, to thereby avoid the danger of a portion of the pile caving in upon the elevator.

Still a furthe-r object is to arrange the machine so that all of the parts are mounted upon and driven by a single shaft to thereby lessen the cost and increase the eiiiciency of the device.

`With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and

Referring to the accompanying drawings,

Ihave used the reference numeral 10 to indicate the longitudinal frame members of my device, and the reference numeral 11 to indicate transverse frame members. v In front of the forward frame member 11 is an inclined frame member 12, which is: extended across to the left-liand frame member 10, at which point a. steerable caster wheel 13 is mounted. At. the right-hand rear corner of the frame is a caster wheel 14, and at the left-liand rear corner is a traction wheel 15. The traction wheel 15 is mounted on an axle 16, which is journaled in sup-ports 17 and 18 and carries spaced bevel gears 19. f

Extended upwardly from the left-liand frame member 10 are a pair of spaced parallel supports 20 and 21, havingbearings 22 at their upper ends designed to receive a shaft 23.

Pivotally mounted on the shaft 23 between the supports 2O and 21 is an elevator 24 comprising spaced side wall members 25, a sheet iron apron member 26, chains 27, slats 28 extended between and secured to the chains 27, and outwardly projecting pins 29 fixed in the slats 28. yAt the forward lower end of the conveyer 24 is the driving shaft 30 therefor, which extends outwardly and is provided with a sprocket 31 at its outer end.

Adjacent to the support 20 a large pulley wheel 32 is secured to the shaft- 23 and designed to receive a belt 33 which is extended through the pulley 34 of an engine 35 which is mounted on the frame of the machine. Adjacent to the pulley 32 on the shaft 23 a sleeve 36 is rotatably mounted, and sprockets 37 and 38 are secured to the sleeve 36 adjacent to either end thereof. The sprocket 38 a chain 39 with the sprocket of the sprocket 38 will and cross bars is connected by 31 so that rotation impart rotation to the chains of the eleva-tor 24.

A second frame designed to support agitating devices is also pivotally supported upon the shaft 23, and compriseslongitudlnal frame members 40 and 41. The inner end of the member 41 is pivoted directly upon the shaft 23 and is spaced from the elevator 24 and support 21 by spacing collars 42. The inner end'. of the member 40 is pivotally mounted on the sleeve 36 between the sprockets 37 and 38 and spaced from the latter by similar spacing collars 42. The members 4() and 41 are rigidly connected to each other by means of a transverse frame member 43.

A crank shaft 44 is journaled in the outer endsof the members 40 and 41, and a rock shaft 45 is journaled between the members 40 and 41 intermediate of the crank shaft 44 and brace 43. Pivoted to the rock shaft 45 are guide members 46 designed to slidably receive bars 47 and 48. The bars 47 and 48 are provided with strap bearings 49 adapted to coact with the crank portions 50 of the crank shaft 44. Secured'to the outer ends of the bars 47 and 48 are agitating devices which will be hereinafter more fully described.

At the end of the shaft 44 adjacent to the support 40 is a pinion 51 designed to mesh with a pinion 52 mounted on a stub shaft 53 which is journaled in the support 40. Fixed to the stub shaft 53 is a sprocket 54 designed to receive a chain 55 which is extended over thesprocket 37.

From the construction of the parts just described it will be seen that rotation of the sleeve 36 will impart rotation to the crank shaft 44 in an opposite direction to the rotation of the shaft 30 of the elevator 24. Rotation of the crank shaft 44 will cause the agitating devices at the ends of the bars 47 and 48 to move in a substantially oval path.

At the outer end of the sleeve 36 are notches 56 designed to coact with teeth 57 of a sleeve 58 which is slidably but nonrotatably mounted on the shaft 23 by means of a pin 59 and slot 60.

At the outer end of the shaft 23 a sprocket 61 is fixed to the shaft and carries a chain 62. vThe chain 62 is extended around a sprocket 63 mounted on a shaft 64 which is extended forwardly to a gear box 65. The gear box 65 contains change speed gears of ordinary construction, whereby rotation of the shaft 65 may be transmuted to several speeds of the drive shaft 66. The drive shaft 66 is provided with the universal joint 67 and extends rearwardly to position adjacent to the bevel gears 19, where a bevel gear 68 is fixed to the shaft 66. A link 69 is pivotally mounted on the shaft 66 adjacent to the bevel gear 68, so that the shaft 66 may be slid from side to side on the support 70 so that the gear 68 may be meshed with either of the gears 19 or held out of mesh with either of the gears.

From the construction of the parts just described it will be seen that the sleeve 58 may be moved to throw the elevator and agitating devices into or out of operative connection with the shaft 23 to thereby impart rotation to the former, if desired. lThe link 69 may be moved to impart rotation from the shaft 23 to the traction wheel 15 in either direction, or the shaft 23 may be disconnected from the traction wheel.

For controlling the movement of the sleeve 58 and the link 69 I provide the following means:

Adjacent to the rear end of the main frame 1 provide an upright 71, at the top of which is pivoted a bell crank lever 72 having at one one end an elongated spline 73 designed to coact with an annular recess 74 in the sleeve 58. Movement of the lever 72, therefore, controls the movement of the sleeve 58 and the connection of the shaft 23 to the elevator and agitating devices.

Extended through the support 71 near the bottom thereof, is a shaft 75 having at its rear end an upwardly extending lever76. At the forward end of the shaft 75 is a downwardly extending link 77 which is pivotally connected to the right-hand end of the link 69. Movement of the lever 76 throws the gear 68 into engagement with either of the gears 19 or out of engagement with said gears. j

The gear box 65 is provided with an upwardly extending rock shaft 78 designed when rocked to control the shifting of the gears within the box. An upwardly and rearwardly extending link 79 is fixed to the right-hand end of the shaft 78. Pivoted to the right-hand side of the support 71 is a lever 80 which is connected by the link 81 to the arm 79. Movement of the lever 80, therefore, controls the shifting of the gears in the gear box 65.

Fixed to the lower edges of the support 40 and to the lower edges of the elevator 24 are segmental worm gears 82 designed to coact with worm gears 83. The worm gears 83 are mounted on shafts 84 and 85 which are journaled in a support 86 extended upwardly from transverse frame members 87 of the main frame. At the right-hand end of the shafts 84 and 85 are bevel gears 88 and 89. 1t will be seen that rotation of the bevel gears 88 and 89 will cause rotation of the worms 83, thereby causing a swinging of the supports 40 and 41 and the elevator upon the shaft 23.

Adjacent to the support 71 on the main frame is a second support 90 having at aeeaeio either side adjacent to its upper end, `shafts 91 and 92 journaled therein. At the rear end of the shafts 91 and 92 are xed hand wheels 93 and 94, and at the forward end of said shafts are fixed bevel gears 95 and 96 designed to mesh with the gears 88 and 89 respectively.

It will thus be seen that rotation of the hand wheels 93 and 94 will cause vertical adjustment of the agitating devices and of the lower end of the elevator 24.

Journaled in the support 90 is a vertical shaft 97 having a steering wheel 98 at the upper end thereof. A chain 99 is wrapped around the shaft 97 and around the shank 100 of the steering wheel 13, whereby rotation of the shaft 97 may impart rotation to the shank 100 and corresponding movement of the steering wheel 13..

The agitating devices mounted on the bars 47 and 48 may be of any desired form to suit the work which is to be done. l preferably make the bars 47 and 48 out of flattened resilient strips of material and provide cross bars 101 of similar material at their outer ends.

Fixed to the cross bars 101 in position spaced vfrom each other, are substantially parallel teeth 102 preferably also composed of resilient material and provided with an inwardly' extending lug 103 having an opening therein designed to receive a rivet or bolt 104, whereby' the teeth may be secured to the cross bar 101. The teeth are also provided with shoulders 105 designed to coact with the cross bar to further prevent displacement of the teeth.

Where the agitating devices are to be used for moving sand or well loosened dirt to position where the elevator may act upon the material, a closure member 106 formed of light sheet steel or similar material may be secured to the teeth by means of U-bolts 107, and an up-turned edge 108 to change the agitating devices from forks into shovels.

Where the elevator 24 is of considerable length, an auxiliary support may be provided at the right-hand end of the machine, comprising a bar 109 pivoted to the elevator 24 and slidably received within a guide device 110 which is pivotally mounted in the bracket 111 secured to the main frame. Set screws 112 may be used for locking the bars to the guide device 110 for holding4 the bars against movement thus holding the end of the elevator 24 supported.

In the practical operation of my improved device it will be understood that the machine is designed to be furnished as shown, but without the engine, so that the purchaser may use any engine which he may have, or may use the machine engine for other purposes when he is not using the machine for loading.

ln order to compensate for variations in power and prevent breakage of the machine, 1 provide the belt 33 as a connection between the engine and the main shaft 23 so that some slippage may occur if necessary. If it is desired to load a pile of hay, straw or fertilizer with my improved machine, the

one side of the pile until the entire pile has` been loaded. In this situation it will be seen that when the center of the pile is reached there will be a tendency for the machine to dig in along the bottom of the pile, thereby leaving an overhanging ledge which would be liable to cave in upon the elevator and agitating devices, and possibly injure the machinery. By means of the adjustment of the agitator supporting frame it will be seen that the agitating devices may be moved to position where they will tear down the material at the top of the pile so that no danger will exist of a cave-in, and so that all the material picked up by the elevator may be thoroughly pulverized and broken up before it is brought into contact with the elevator. The agitating devices may be so arranged that they will rake the material to be loadedl up upon the elevator if desired.

Some changes may be made in the construction and arrangement of the various parts of my device without departing from the essential features and purposes of my invention, and it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.
