GRAIN-LIFTING ATTACHMENT FOR HARVESTERS.

N 0. 843,164. Specification of Letters Patent. Patented Feb. 5, 1907.

Application filed March 2, 1906. Serial No. 303.874.

To all whom it may concern.- applied to the guard-fingers of the cutting Be it known that 1, ALBERT H. MC apparatus of harvesters and binders, it being CUTCHAN, a citizen of the United States, reintended in practice to apply one of the grainsiding at G-oltry, in the county of Woods and lifting devices to each guard-finger of the 5 Oklahoma Territory, have invented a new cutting apparatus.

and useful Grain Liftin Attachment for The lifting device, which is preferably Harvesters, of which the following is a specimade of cast or malleable iron, comprises a fication. lower member 1 and an upper member 2, This invention relates to harvesters and converging at the front in a point or apex 3. 1o binders, and especially to the cutting appa In Figs. 1 and 2 of the drawings the lower ratus of this class of machines. member 1 has been shown as provided at its The invention has for its prime object to rear extremity with a socket 4, adapted to relift or to elevate grain that has been broken ceive the forward end of a guard-finger 5 of down either on account of being overripe and ordinary construction, it being understood I 5 heavy or by being beaten down by rain or by that the socket 4 may be modified to adapt it hail, so as to cause the straw to be severed for engagement with the guard-fhagcrs of vaproperly by the cutting apparatus and the rious machines.

lifting device, grain that is down will be en gaged by the apex 3 of the lifting devices connected with the guard-lingers of the cut ting apparatus and will be gradually lifted sufficiently to cause the stems to be severed at the proper distance from the ground, the

heads being guided over the rearwardly and upwardly inclined members 2 onto the grainplatform, thus avoiding loss and waste of material.

By reason of the arrangement of the several parts as herein described, and shown in the drawings,it is possible to provide a simple and strong grain-lifting attachment for a finger-guard. At the same time the attachment is light and will not add materially to the weight of the machine to which it is attached or have a tendency to tilt the forward end of the finger-guard to which it is attached in a downward direction. As the brace 9 extends vertically from the lower member 1 to the upper member 2 and as the limbs 10 10 extend along the said members from the brace 9 toward the apex or point of con vergence of the said members, those portions of the finger-guard lying between the brace 9 and the apex 3 are strengthened and made rigid, while the rear end'of the member 2 is free to vibrate, which vibration will have its effect in untangling the grain and erecting the In other words, the forward portion of the grain-lifter isso braced as to be devoid of vibration, but serves as an entering wedge, while the rear end of the upper member 2- is free to vibrate.

I am aware that patents have been granted for grain-lifters which in general appearance somewhat resemble the construction herein vices are either objectionable for the reason that they add excessive weight to the machine to which they are applied or by reason of injudicious arrangement of parts are not braced and-strengthened at the points subjected to the greatest strain; hence are frail and are liable to be twisted out of shape as the result of slight use.

Having thus described the invention, what is claimed is 1. A grain-lifting device adapted to be attached to the finger-guard of a harvester consisting of a forwardly-extending member, a member extending rearwardly from the forward end of said forwardly-extending member and being inclined at an angle with relation to said forwardly-extending member, a U-shaped limb inserted between said members and having its ends extending toward the point of connection between the two said members and inclined toward each other, the outer sides of the ends of the limb being secured along their entire length to the said members and being concave to conform to the contour thereof.

2. A grain-lifting device adapted to be at tached to the finger-guard of a harvester consisting of a forwardly-extending member, a member extending rearwardly from the forward end of said forwardly-extending memher and being inclined at an angle with relation to said forwardly-extending member, a brace extending vertically between the forwardly extending member and the rearwardly extending member and attaching with both and having limbs which extend therefrom along both of said members toward the point of juncture only and bracing that portion of the lifting device lying between the brace and the point of juncture of the forwardly and rearwardly extending members and leaving the rear portion of the rearwardlyextending member free for vibration.

In testimony that I claim the foregoing as my own I have hereto aliixed my signature in the presence of two witnesses.
