FRAME CONSTRUCTION FOR CORN HARVESTERS Filed Oct. 8, 1928 2 Sheets-Sheet 2 John/fowe ll,

Patented Dec. 29, 1931 JOHN POWELL, OI KOKOMO, INDIANA FRAME'CONSTRUGTION non con v nanvns'rnns Application filed October S, 192s. sea r No. 311,195.

' This invention relates to improvements 'in corn harvesters, and more particularly to a novel frame .construction for a machine of the type disclosed in my co-pending application Serial No. 18,718, filed March 27 1925. An object of the invention isto provide an improved frame, whereby the picking and gathering elements may be readily attached or detached, thus fa cilitating the original as- I sembly or the replacement of a new gatheringunit without requiring the dismantling of the whole machine, in the event that they said unit becomes broken or is otherwise in need of repair or replacement.

Another object oftheinvention is to provide a frame construction including a number of standardized units or parts, which permits of the entire frame being shipped in a knocked-down? condition if desired, and

Z9 easily assembled to provide a rigid frame,

which will be strong and durable in use.

A further. object of the invention is to pro-' vide for the assembling of the gathering and picking units complete at the factory and then shipping them separately. from the frame to the user, who can readily attach them to the frame by bolting each in three places. I With the above and other objects in view which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts herein- 1 after more. fully. described, illustrated and claimed. g

A preferred and practical form of the invention is shownin'the accompanying drawings, in which Figure l is a rear view of my assembled main frame construction withgathering and husking units removed. 7 a

A pair of upright bracing and supporting members2 having basesformed of laterally extending ears 3 are positioned on and secured to and between the spaced rails 1,:by the bolts 4. ,These members 2 'extend-up- 7o wardly and'th'enare angled forwardly, and are provided adjacent their mid-sections with thelaterally and oppositely disposed sup porting ears 5, While their upper ends are 1* formed with the right angled heads 6 which extend to both sides of the bodyv ofthe members One brace member 2 ispo'sitionedat one end of the rails 1, while a second similarlyconstructed member is secured at the mid dle of the said rails l. A top rail 7 formed of angle iron is securedtoth'e heads 6 of the members 2, and extends. approximately the length of the main frameerails 1.

Twopairofbearing plates 8 are formed substantially rectangular in shape and an- "gled rearwardly adjacent their upper ends at 9, and are notched or cut away at adjacent edges as indicated at 9a, Fig. 7 ofthe drawings. Each plate 8 is provided with a bolt opening 10 at its lower. end and a bolt open mg 11in its rearwardly angled portion 9 for attaching the same by means of bolts 12 and 13tothe laterally extending supportinglears 5 and to the under surface of the angle heads 6, respect'iv'ely. The bushings 14: carried by the plates- 8 serve as bearings for the shafts 16 and 17 which aregeared together through the sprockets 18, and drive the gathering chains and snapping rolls of the picking and gathering unit 19.

Spaced pairs of forwardly extending angle braces 20 are secured to the main rails 1, and are attached to the frame bars 21 of the gathering unit 19, see Fig. 2 of the drawings.

Supporting wheels 22 are mounted at the opposite ends of the main rails 1 in any desired manner, either on stub axles or on a continuous axle extending the length of the said main rails.

It will be understood that the gathering unit 19 will be completely assembled at the factory and that when it is desired to place the same in position on the frame, it is only necessary to fasten bolts through the

bolt openings

10 and 11 in the plates 8, and bolt through the forward end of the angle braces 20, and into the frame bars 21 of the gatherlIlo unit.

The top rail 7 is, as previously indicated, supported transversely of the frame and is secured to the heads 6 of the members 2, while the bolts extending through the openings 11 in the plates 8 also extend through the top rail.

A modified form of bracing member 24 will be attached at the end of the main rails 1 opposite the members 2 and to the top rail 7 by four bolts which extend through the head 25 of the brace member. Inwardly extending cars 26 are formed adjacent the top of the member 24 and are provided with bolt openings 27 through which pass the bolts for sup porting the transmission shaft 28 and bevel gears 29.

From the foregoing, it will be apparent that I have devised an extremely durable and serviceable form of frame construction, in which the essential parts thereof may be quickly assembled or dismantled. It will be further seen that the gathering unit may be replaced by another unit when desired by merely attaching in three places, thereby eliminating waste time and expense of buying a complete harvester.

Without further description it is thought that the features and advantages of the invention will be readily apparent to those skilled in the art, and it will of course be understood that changes in the form, proportion and minor details of construction may be resorted to, without departing from the spirit of the invention and scope of the appended claims.

I claim:

1. A frame for corn harvesters comprising main rails and a top rail spaced therefrom, a plurality of brace members interposed between said main rails and top rail, supporting wheels carried by said main rails, laterally extending ears on said brace members, bearing plates secured between said ears and said top rail, and gear mechanism operatively supported by said bearing plates.

2 A frame for corn harvesters comprising mam rails and a top rail spaced therefrom a plurality of brace members interposed between said main rails and top rail, supporting wheels carried by said main rails, laterally extending ears on said brace members, bearing plates secured between said ears and said top rail, gear mechanism operatively supported by said bearing plates, and means on said brace members and rails for supporting a gathering unit on said frame.

3. A frame for corn harvesters comprising main rails and a top rail spaced therefrom, a plurality of brace members interposed between said main rails and top rail, supporting wheels carried by said main rails, laterally extending ears on said brace members, notched bearing plates secured between said ears and said top rail, gear mechanism operatively supported by said bearing plates, and forwardly extending brace arms supported by said main rails for supporting a picking and gathering unit.
