To all rwhom it may concern.'

Be it known that I, WALTER S.. HARRISON, a citizen of the United States, residing at Tabor, Vin the-county of Bonhomme, State ofi employed to transfer the corn to the shelling machines.

The invention aims as a primary object to provide a novel construction, combination and arrangement of parts, the details of which will appearin the'course of the following description in which reference is had4 to the accompanying drawings, forming a part of this specification, like characters of reference designating similar parts throughout theseveral views, wherein: n

Figure 1 isa side elevation of a conveyer constructed in accordance with the present invention. Fig, 2 is a top plan view thereof. Fig. 3 is a central longitudinal sectional view thereof. side elevation showing in detail a hand lever mounted atthe front end of conveyer.` Fig.

' 5 is a section on the line 5-5 of Fig. 2. Fig.

6 is a detailed view showing the construction and mode of assemblage of a preferred form of gathering hook. Fig. 7 is a similar view of a modified form of gathering hook.

In the accompanying drawings, the numeral 10 designates generally the elevator Vframe comprising a rectangular base 11,

which has connected thereto near one end of the same vertical posts 12, `the latter, together with thel front ends of the side bars of the base 11supportin'g inclined bars 13 constituting the side bars `of the elevator proper, the latter comprising transverse cleats 15,

. supported by parallel chains 16, the cleats 15 having connection with said chains at suitable equi-distant points. The bars` 12 are braced at their upper ends by a cross piece 17 and below the cross .piece 17 are Aprovided Fig. 4 is an enlarged fragmentary with suitable bearings for a transverse shaft 18, the latter carrying on the inner side of the posts 12 sprocket wheels 19, over which the chains 16 are trained. The chains 16 are likewise trained under sprocket wheels 20 mounted on stub shafts 21 at the lower ends of the bars 13 and over sprocket wheels 22 arranged at the ends of the side bars of the base 11, the said sprocket wheels 22, being mounted on a transverse shaft 24. Adjacent the sprocket wheels 20, idler sprocket wheels 25 mounted on stub shafts 26 are provided, the

vsprocket wheels 25 bearing agalnst the upper laps of the chains 16 and serving as guides therefor, whereby said chains may be turned from an inclined line of travel to a horizontal line of travel.

Theside barsnear the front end of the base 11 support short vertical posts 27 connected at theirupper ends by a cross bar 28 and reinforced by diagonal braces 29 secured thereto and to the said side bars of the base 11. The bar 28 is provided at one side thereof with a bearing 30 through which projects a longitudinal shaft 31, the latter likewise projecting-through bearing sleeves 32 formed on a bracket 33, the latter being secured to one of the posts 12 and being formed as a bearing for a stub shaft 34 disposed at right angles to the shaft 31 and carrying a bevel inion 35 which meshes with and' is driven from a smaller bevel pinion 36 carried upon the shaft 31. The end of the shaft 31 pro- Vvjects into ahorizontal sleeve 37 constituting a bearing therefor, and connected by a web B8 with a vertical sleeveV 39, the latter surrounding a drive shaft 40 in gear with the corn shelling mechanism. The sleeve 39 is provided with an arm 41 of substantial L shape and including an upwardly extending ortion to'whioh is secured a collar 42 the latter serving as a stop and also as a bearing for the hub 43 of a bevel pinion 44, the latter being arranged at the end of the sleeve 37 and being in mesh with and driven from a similar pinion 45 provided on the shaft 40.

The hub 43 is formed with a clutch face 46 and splined upon the shaft 31 for sliding movement is a clutch yoke 47 formed with a circumscribing groove 48in which is engaged the yoked end 49 of a pivoted hand lever 50, the latter working about a rack quadrant 51 and being provided with a trigger operated pawl 52 for engagement with the teeth of said rack quadrant. The shaft 31 at its Patented May 11, 1909,

front end, has connection by means of universal or gimbal joint 53 with a short length shaft 54, j ournaled in a casting 57 and carrying a bevel pinion 58.

The gathering mechanism comprises a rectangular box-like frame 59 strengthened by interior reinforcing (not shown) and incliidin vertical side walls 60 and end walls 61. o one end of the end walls 61, bearings 62 are secured, the latter being provided for a vertical shaft 63 which projects through a sleeve 64 forming a part of the casting 57 and which carries a bevel pinion 65 in mesh with and driven from the pinion 58. The shaft 63 projects downwardly and is designed for detachable engagement in a bearing 66, secured to the rear end of the base 11. The

box-like frame 59 also includes top and bot-- tom walls 67-and 68 which project beyond the sidewalls and are formed with opposed inwardly extending portions 69 coacting with said side walls to afford upper and lower grooves 70 and 71 through which upper and lower chains 72 and 73 have movement, the chains 72 and 73 traveling entirely around the frame 59 and being trained over upper and lower sprocket wheels 74 and 75 arranged at the end of said frame, the sprockets 74 and 75 being carried upon the shaft 63.

Secured to the bottom wall 68 at one side thereof, is a laterally projecting trough 77 having a slanting bottom 78.

The chains 72 and 7 3 conjointly support a plurality of gathering hooks 79 of novel construction and illustrated more particularly in Fig. 6, in which a curved member 80 is shown that constitutes the hook proper. rlhe member 80 is of angle iron construction and has its angularly curved end pointed as at 81. At its other end, said member is formed with a horizontal lug 82, by'means of which said member is secured to a link of the chain 71, the portion 82 lying against one side of the said link. The lug 82 is connected to said link by means of a vertical pin 83, the iii 83 serving as a pintle for a friction rol er 84 which rests upon the base of the groove 71 and bears against the sides thereof. 4The hooked member 80 constructed and assembled with relation to the chain 73 in this manner, has fixed connection with a member 85 which includes a vertical portion 86 terminating at its upper end in an angular lug 87 which is secured to one of the links of the chain 72. The member 85 also includes a rearwardly extending bow-shaped curved portion 88 which projects in a horizontal plane from the point of connection of the member 85 with the member 80 and which at its rear end, is designed to bear against the outer f aces of the portions 69 as a brace.

In liig. 7, there is illustrated a modified a member 89 of angle iron shape and formed 65 at one end with a lug 90, similar in construction and for a similar purpose to the lug S2. The member 89 has its body bow-shaped as at 91 and then curved rearwardly and bent into hook form as at 92, the major curved portion of the hooked end 92 bearing against the portions 69. The member 89 has rigid connection adjacent its portion 92 with a vertically extending member 93 terminating in a lug 94 similar to the lug 87 and designed for connection with one of the links of the chain 72. Secured to the rear end of the base 11, is a chute 95 constructed with a recess 96 to surround the shaft 63, the chute 95 being provided to transfer coin from the trough 77 to the elevator 14, which in turn i discharges into a lateral downwardly inclined transferring chute or spout 97, through which the corn gravitates to the shelling nicchanism.

The pinion 35 has formed on its hub a sprocket wheel 98, the latter serving, by means of a chain 99, to drive the shaft 18 of the elevator 14, the chain 99 being trained over a sprocket 100, provided on the projecting end of said shaft.

Manually operable means are provided for moving the conveyer as an entirety, in its rotatory adjustable movement, over the ground. Projecting laterally from the top and bottom walls 67 and 68 of the frame 59 is a bracket 101 of suitable construction to which is pivoted a pointed ground engaging dog 102. The lateral movement of the conveyer is effected by a lever 103 having a pointed ground engaging end 104 and formed in its body with a longitudinal slot 105, through which is engaged a laterally projecting pivot pin 106, carried by the bracket 101. In moving the coiiveyei the lever 103 is raised until the pivot pin 106 iinpinges the I lower edge of the slot and said lever is then drawn rearwardly and its end 104 en` gaged in the ground. The lever 103 is then pushed forwardly as far as possible and raised again, such raising being necessary in order that its end 104 may clear the I ground when the lever is drawn rearwardly.

After each operation of the end 104, the dog 102 is pushed into the ground by the foot se as to prevent the conveyer from working rearwardly under the action of the connected operating parts.

It will be understood that the frame 59 and its adjuncts may be detached from the elevator mechanism and its adjuncts by disassenibling the members of the ginibal joint 53. The frame 59, by virtue of the manner of its connection with the shaft 63, may be set at selected positions about said shaft as a pivot with relation to the elevator frame through the means described. The gearing described drives the elevator frame and the form of gathering hook, such form comprising conveyer chains 72 and 73 simultaneously, irrespective of the position oi' the frame 59 with relation to the frame 10.

The invention is simple in its structural details, inexpensive to manufacture and practical and efficient in use.

From the foregoing horizontal portion designed to bear against said lower chain as a brace. l
