G RAlN- HARVESTER.

SPECIFICATION forming part of Letters Patent No. 597,635, dated January 18, 1898.

Application filed March 25, 1897.

To all whom it may concern.-

Be it known that 1, ROBERT IV. OOOMBS, of McOanna, in the county of Grand Forks and State of North Dakota, have inventedcertain new and useful Improvements in Grain-I-Iarvesters; and I do hereby declare the follow ing to be a full, clear, and exact description of the invention,-such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a new and useful attachment for harvesting-machines and is intended to be used in connection with the aprons thereof to prevent the grain after having been cut from clogging or otherwise becoming entangled therewith, the object being to provide a device of this character which shall be simple and inexpensive in construction, which can be readily applied to the harvesters new in use, and which is particularly well adapted for use when harvesting flax or other products having a tendency to stick to the apron.

, My invention comprises certain novel features of construction and arrangement of parts whereby the above and other imporrant advantages are gained, as will be hereinafter described, and specifically defined in the appended claim.

In the accompanying drawings, Figure 1 represents a detail perspective view of a portion of a harvesting-machine having my invention applied thereto. Fig. 2 is a central longitudinal section of the same,lookin g from the opposite side. Fig. 3 is a detail perspective view of my invention detached, and Fig. 4 is a detail View of a modified form of my invention.

Similar reference-numerals indicate corresponding parts in all the figures of the drawings.

1 represents the platform, 2 the apron, 3 the cutter-bar, and 4 the elevator, of an ordi nary harvesting-machine, and as these may be of any ordinary or known construction no detailed description thereof is deemed necessary,

My improved attachment is arranged immediately behind the cuttenbar and adjacent to the edge of the apron, and consists of a bar of steel or iron 5, having end supports or Serial-1N0. 629,142. (No model.)

lugs 6 formed thereon, the latter being provided with openings for bolts 7, which serve to fasten the bar to the frame of the platform. The bar 5 is so arranged that its upper edge will lie about upon alevel with the slats 3 of the apron, and one end of the bar is arranged to extend beyond the outer end of the apron, while the other end hasan extension S,which is turned or twisted at the point 8, so that it may lie fiat upon the slats of the apron 9 of the elevator i, which latter is of any ordinary or usual construction.

The grain or other product after having been cut by the knife falls over the bar 5 onto the apron 2, the ends of the stocks resting upon the edge of the bar, while the remaining portion thereof will lie upon the apron and between the slats, by which means they are conveyed to the elevator-aprons. The bar 5 will thus relieve the apron of a great portion of the weight of the grain and serves to keep one end thereof raised slightly above the apron, and by reason of the bar being arranged to lie close to the edge of the apron all possibility of the grain becoming entangled therewith is positively prevented and its delivery to the elevator-aprons greatly facilitated.

The extension 8 of the bar 5 serves to relieve the canvas of the elevator over which it extends from a heavy strain and ata point where a drag is liable to occur, and it is to be understood that the attachment heretofore set forth is intended especially for use on a harvester for handling and elevating flax, which has a tendency to pack and gather at certain points on the apron and elevator and impede the proper operation of said parts.

In practice I may bend the upper edge of the bar 5, so as to form a flange 5 at right angles thereto, under which flange apron 2 and slats 3 will travel, and this construction will aiford greater security against the entanglement of the grain with the apron. I reserve the right to make this change and otherwise alter the parts herein described in such manner as may be considered to lie within the spirit and scope of my invention.

It will thus be seen that my invention provides in a simple and effective manneran attachment for harvesters which is particularly ICO well adapted for the purpose for which it is intended, which is not easily gotten out of order, and which can be readily applied to the harvesting-machines at present in use, it being obvious that by its use the heavy strain put upon the apron is very materially reduced and the wear and tear of the canvas mate- I rially lessened.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

An attachment for a harvesting-machine, comprising a bar arranged adjacent to the platform-apron, and provided with lugs or ROBERT XV. COOMBS Witnesses:
