Application flied July 12, 1918 Serial No. 244,530.

To all whom it may concern: Be it known that I, FREDERICK I. FRIED-- LINE, a citizen of the United States, and. a resident of Kentland, in the county of New ton and State of Indiana, have invented certain new and useful Im rovements in Corn- Pickers, ofwhich the ollowing is a specification. v My invention relates to corn pickers, articularly to the improvement of provi ing therefor a picking an corn husking parts. One important object of the invention is to locate the engine on the corn picker in such position that it can be very readily controlled from the drivers seat and its weight will cooperate with the other machine parts to produce perfect balance. Another object is to provide improved supporting structure for the engine, the structure being prefer ably such that nos ecial means or additions are necessary on securing the structure to the machine frame. Another feature of the invention resides in improved transmission mechanism between the engine and the corn picking and husking parts to be driven.

The various features of my invention are disclosed on the accompanying drawings in which-- Figure 1 is a plan view of particularly the supporting frame-work of a corn picker, with the engine supporting frame-work mounted on and secured thereto,

Fig. 2 is a front view of the parts shown in Fig. 1 but with the engine in place,

Fig. 3 is a rear elevational view,

Fig. 4 is a side elevational view of the engine supporting frame-work and part of the power transmission train, and

Fig. 5 isa rear view of the engine supporting frame.

The corn picker supporting body is shown constructed of stock bars, mostlyangle iron, and comprises the sidebars 10 and 11, the front bar 12, the intermediate transverse bar 13, and the rear bars 14 and 15. The axle 16 supported from the-machine body hasthc tractor wheels 17 and 18 at its ends. Secured to the inner sides of the wheels are the chain sprocket wheels 19 and 20. The reach beam or tongue 21 is secured at its inner end to the bars 12' and 13 and at its front end the truck or fore carriage is piv- (gas engine for driving the corn.

baa thereto, draft animals being hitched to this truck by means of a tongue or other apparatus.

- Extending parallel with the rear bars 14 and 15 .is the transmission shaft 23 on which are the sprocket pinions 24 and 25 in line with the sprocket Wheels 19 and 20. In corn pickers as usually operated, chains connect these sprocket wheels with the pinions so that the turning of the .tractor wheels as the machine is drawn along will cause turning of the shaft 23 and operation of the picking, husking and other mechanisms which are connected by suitable transmis sions with the shaft'23. However, this arrangement puts: on the draft animals the entire burden of operating the machine in addition 'to'the burden of drawing the machine along. An important feature of my invention is therefore to provide a gas engine on the machine from which the operating power is obtained instead of from the tractor wheels, this cutting the work of the draft animals down to just the pulling of the machine along the ground.

At the left side of the corn picker the inclined corn receiving, guiding and picking apparatus P is shown more or less diagrammatically, while at the right side of the machine the h'usking apparatus H is shown in outline. The drivers seat S'is between the picking and husking mechanisms and in front of the chute or elevator E leading from the picking to the husking mechanism.

In accordance with my invention I locate the engine between the picking and husking' mechanism and between the elevator and the drivers seat so that the driver can readily control and take care of the engine from the seat and so that the balance of the entire machine is preserved. For supporting the engine a simple supporting frame structure of stock material is provided and this supporting frame is rigidly secured to the machine frame in common with various parts thereof practically without requiring any additional; supporting or securing arrangements. This engine sup orting frame-work comprises the left and ri ht side frames (1 and b, each of which is pre erably bent up from a single piece of angle bar. The side frame a has the horizontal section 26, the front downwardly extending section or leg 27, and the upwardly inclined.

rear end 28. The side frame I) has the horizontal section 29, the front downwardly extending section or leg 30, and the rear downwardly extending section or leg 31. Cross braces 32 and 33 secure together the front legs 27 and 30 and gusset plates 34 are preferably placed in'the angles between these legs and the horizontal sections of the side frames.

Describing now the manner of securing the engine sup )orting frame in place, the lower end of the leg 27 is secured to the fittingfi35 forming part of the picker and secured at the left end ofthe front-bar 12, the fitting forming a support for the rear end of the brace bar 36 w iich is secured at its front end to the tongue 21. Ordinarily, a pin is used for securing the brace to the fitting but'in order to secure the engine supporting frame I remove the pin. and use a bolt 37, the leg 27 having the hole 38 for receiving the bolt so that the leg will be rigidly secured against the inner face of the fitting as shown. The upwardly inclined end 28 of the side frame a extends underneath the elevator E to which it is secured by a bolt 39. The angle piece 40 secured to the chute and side frame gives additional support and a brace 41 extends. from the frame top 26 and is secured at its lower end to the intermediate cross bar 13 of the machine body by means of a bolt or rivet.

The lower end of the leg 30 of the side frame I) is secured to the tongue 21 by'receiving one of the bolts 42 which form part of the picker frame. The leg 31 of the frame I; is bent to rest on the tongue 21 and is secured by means of the bolt 43 which ordinarily secures to the tongue the cross brace 44 forming part of the picker frame. Thus available bolts or other parts are taken advantage of for securing the engine supporting frame-work and consequently no labor is necessary for forming additional bolt holes or for preparing special supporting points.

he parallel horizontal sections 26 and 29 of the side frames a and b are provided with bolt holes 45 and 46 for receiving bolts 47 by means of which a pillow block 48 can be readily secured, this pillow block formin a support for a gas engine G. Depen ing from the rear end of the pillow block 48 is the bearing 49 for the front end of a transmission shaft 50, the rear end of the shaft being journaled in the bearing standard 51 mounted on the cross bar 52. This cross bar is secured at its right end by means of the angle piece 53 to the brace 54 which together with the diagonal brace 55 extends upwardly from the cross bar 15 to assist in the support of the husking mechanism. At its left end the cross bar 52 is secured to the frame-work of the picking mechanism and its support is strengthened by the brace 56 extending upwardly from the bar 15.

The shaft 50 carries the sprocket wheel 57 which is connected by a chain 58 with the sprocket pinion 59 at the end of the engine shaft 60. At the end of the shaft 50 is a sprocket wheel 61. at its left end the bevel gear 62 which meshes with the bevel gear 63 on the shaft '64 which extends transversely of the bars 14 and 15. The rear end of shaft 64 carries the sprocket wheel 66, the chain 67 passing around this sprocket wheel 66, the sprocket wheel 61, and the sprocket wheel 68 on the shaft 69 which connects "with the various picking rolls and other apparatus in the picker section P of the machine. Preferably an idler wheel 70 for-keeping the chain 67 taut is provided. Power is thus transmitted from the engine to the picker mechanism and to the shaft 23 this shaft having the sprocket wheel 71 which by means of a chain (not shown) will be connected with the husking apparatus H.

By thus providing an engine on a corn picking and husking machine work can be more efliciently accomplished and less draft animals are necessary, the picking and husking operations being accomplished independently of the speed of travel of the draft animals. By mounting the engine between the picking and husking apparatus and behind the drivers seat it is readily accessible to the driver for operation and control, and furthermore, its location stabilizes and balances the machine and the load on the trac- The shaft 23 has tor wheels is efiiciently equalized. By so repairs.

I do not of course desire to be limited to the exact constructions and arrangements shown and described as changes are no doubt possible which would still come within the scope of the invention. I claim as follows: 1. In a harvesting machine comprising a corn picking section, a receiving section, a conveyer between said sections, and a seat between said sections and in front of said conveyer, a driving engine, and a supporting frame for said engine secured between said sections and said conveyer and seat. 7 2. The combination with the supporting framework of a corn harvester, and a draft tongue secured thereto and extending forwardly therefrom, of an engine supporting frame comprising two side members braced and secured together, one of said side members being secured to said tongue and the other side member being secured to said supporting framework, and an engine mounted on said supporting frame.

3. The combination with a corn harvester, and a draft tongue secured to and extending forwardly from said body, a brace secured to said body and to said tongue, of an engine supporting frame comprising two sides, one of said sides being secured at its front end to said body in common with said 10 brace and secured at its rear end to said framework, the other side of said supporting frame being secured to said tongue, and an engine mounted on said supporting frame.

In witness whereof, I hereunto subscribe l5 my name this 9th day of July, A. D. 1918.

FREDERICK}. FRIEDLINE.
