(Cl. 214-143) This invention relates to a grain conveyer and loader, the general object of the invention befeatures of construction and in the combination l and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims. I

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views,

and in which:

Figure 1 is an elevation of a truck to which the invention is applied with parts broken away. Figure 2 is a fragmentary view showing the top part of the truck with the conveyer part of the invention in raised position so that it canbe moved with the vehicle from one place to another.

Figure 3 is a detail side view of the conveyer body with the cradle thereon and showing part of the drive means.

Figure 4 1s an elevational view of the conveyer body and the screw with the driving means, parts being broken away. Figure 5 is a section on the line 55 of Figure- Figure 6 is a perspective view of the cradle.

Figure '7 is a perspective view of the skeleton frame or cage at the lower end of the conveyer body.

Figure 8 is a sectional view through the drive means at the bottom of the vehicle body.

Figure 9 isa perspective view oi the .T-shaped member to which the cradle is connected.

. In these views the letter A indicates a truck and the letter B indicates a body thereon which is open at its top so as to receive the grain or top thereof and it also extends through the bottom of the body where it connects with a gear housing 2. A shaft 3 has its rear end journaled inthe housing 2 and its front end is suitably supported from an un derneath part of the truck where it is connected by the chain and V sprocket meansshown generally at 4 with a driven shaft 5 of the truck. Within the housing 2 theshaft 3 has attached thereto a beveled gear 6 which meshes with a similar gear i on the lower end of a vertical shaft 8 journaled in the tubular member i. A substantially T- shaped member 9 is formed with a tubular stem In which extends into the upper end of the tubular member i and the shaft 8 passes through this stem and through the cross member ii and the upper end of the shaft receives a bevel gear II. The cross member ll of the T-shaped member is provided with the upwardly extending perforated 'lugs l3 at its ends and ad acent one of the lugs IS the cross member is formed witina substantially U-shaped depending part 14. A shaft l5 passes through the perforations of the lugs l3 and has a beveled gear ii thereon meshing with the gear l2 and a straight gear 11 is fastened to the shaft [5 and extends into the channel formed by the part i4. Asubstanthe connecting longitudinally extending bars 21- which carry the pintlesrand each ring-shaped member is provided with an outwardly pressed. part 22 which 'forms an interior groove 23. The cradle slidingly receives the elongated tubular housing 24 of the conveyer mechanism which has a longitudinally extending rod 25 attached thereto which slides in the grooves 23, it being seen that the housing passes through the rings 20. This pipe or rod 25 acts to prevent rotary movement of the conveyer housing in the cradle though the housing can slide in the cradle. A bar 2| of the cradle is bolted at its center to the top of frame M. g

A hub 21 is 'rotatably arranged on oneof the pintles I! and carries a large gear 28 which meshes with the gear ll and a beveled pinion 29 which meshes with a beveled pinion 30 carried by a bracket 3|! attached to the frame l8, .Sald pinion 30 is slidably arranged on a square shaft 3i having its end :portions rotatably arranged in brackets 32 carried by the housing .24. A spiral or screw is carried by a shaft "rotatably arranged in the housing 24 and the upper end of the shaft passes through the closed upper end of the housing where it is connected with the upper end of the shaft 3! by the chain and sprocket means shown generally at A cage or skeleton frame of substantially conical shape is shown at 3B and carries the bearing member 31 at its lower end for the lower end of the shaft 34, the upper end of the skeleton frame being connected to the rings 38 fastened to the lower end of the housing 34. A spout 39 leads from an opening in the upper end of the housing 24 for the escape-of the material lifted by the screw conveyer and as will be seen from Figure 4 the lower end of the conveyer projects from the bottom of the housing so that it can be placed in a pile of grain such as shown in Figure 1 or in a bin containing grain or other material to be lifted.

As will -be seen the T-member 8 will rotate in the upper end of the tubular member I which isheld in a stationary vertical position by the truck body and thus the frame I! and the cradle which carries the conveyer housing 24 can be revolved about a vertical axis without interfering with the transmission of the power from the power plant of the truck to the conveyer screw and the frame I. with the cradle therein can be partly revolved about the shaft I! as an axis which, of course, permits the lower end of the conveyer housing to be swung to different positions to cause the lower end of the screw conveyer to engage the grain from different parts of a pile or in a him. Also, the conveyer housing can be raised and lowered through the cradle to adjust the distance of the lower end thereof from the ground or from the bottom of the bin. When not in use the conveyer housing can be placed in the position shown in Figure 2 so that it can be conveyed from one place to another by the truc It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall.within the scope of the appended claims. t

Having described the invention, what is claimed as new is:

1. A loader of the class described comprising a tubular upright, a frame including a lower part and an upper part pivotally connected together for movement about a horizontal axis, means for rotatably supporting the lower part of the frame from the upper end of the upright for movement about a vertical axis, a cradle passing through the frame and supported in the upper portion thereof, a conveyer housing slidably arranged in the cradle, conveying means passing. through the housing and means for actuating the conveying means.

2. A loader of the class described comprising a tubular upright, a frame including a lower' part and an upper part pivotally connected together for movement about a horizontal axis, means for rotatably supporting the lower'part of the frame from the upper end of the upright for movement about a vertical axis, a cradle passing through the frame and supported in the upper portion thereof, a conveyer housing slidablyarranged in the cradle,

conveying means passing through the housing and means for uating the conveying means, said means incl ding a shaft extending longitudinally on the conveyer housing and spaced therefrom, means for connecting the upper end of the shaft with the conveyer means. a gear slidably arranged on the shaft, gearing carried the cross piece of the T-shaped member having upwardly extending perforated ears, an inverted yoke-shaped frame having the lower ends of its limbs overlapping said ears, a shaft passing through the ears and said lower ends of the yoke frame and pivotally connecting the yoke frame to the ears, a cradle having pintles extending from the side posts thereof which are arranged in the side members of the yoke frame, a conveyer housing of tubular form slidingly passing through the cradle, means for preventing rotary movement of the housing in the cradle, conveying means in the housing, a shaft carried by the housing, means at the upper ends of the shaft for driving the conveying means from the shaft, a gear slidably arranged on the shaft connected with the housing. a hub on one of the pintles,

4. A loading device for a motor vehicle comprising an elongated tubular housing. a screw propeller passing through the same and including a shaft, a. skeleton frame depending from the lower end of the housing. at the lower end of which the shaft is Journaled, a shaft rotatably supported from an exterior part of the housing, means for communicating movement of the lastmentioned shaft to the upper end of the propeller shaft, a tubular upright supported by the vehicle body, a framemember supported for rotary movement in the upper end of the. tubu- :cradle supported in said part of the frame and means for slidably supporting the housing in said cradle and means for rotating the shaft carried by the housingfrom the power plant of the vehicle without interfering with the movement of the parts.
