tion, reference being had to the accompanying drawings.

This invention relates to means for elevating grain and the like, and is especially adapted for elevating grain from the platformcanvas or carrier-apron of a harvester to the binder deck or table.

My invention has for its object to provide a simple and effieient mechanism that will eifect positive elevation of any and all kinds of grain, that will accommodate itself to these varying kinds and conditions of the grain, that will perform its functions with greater ease and accuracy, and that will secure the grain from waste by falling off or being blown oii' the elevator.

In self-binding harvesters the elevation of the grain to the binder-table has been heretofore effected by means of an elevating apron or canvas having cross-bars, that travels upwardly and carries the grain over and on top, where it is exposed to the action of the winds, &(3- This elevating means is disadvantageous in many other particulars, among which maybe mentioned the fact that it does not.

hold the grain compactly while it is being elevated, so that it is delivered on the bindertable in a diffused and scattered gavel; butin my invention the grain is elevated by thelower or under strand of an endless apron, and is held against guides under the elevating mechanism by elastic teeth, which also carry it upwardly between the said guides and elevator.

By this'means the grain is held on all sides the ribs D as it is being elevated.

Referring to the drawings, A designates the frame of the elevator,which is in this instance arranged like the ordinary apron-elevator frame, and consists of side boards, B B, and the inclined bottom 0. On the bottom G are secured a number of parallel guiding and supporting ribs or strips, D, on which the. grain rests as it is being elevated, and each side board, B, carries chain-pulleys E E at its top and bottom. On both of these pairs of pulleys E E travel chain belts F F, the links of which are provided at suitable intervals with lateral lugs or extensions G G, having 6 perforations H. These lugs G G enter the kerfs I I of the bifurcated ends of the crossbars J, and the latter are by this means secured on the chain belts F F, a bolt, K, being passed through each bifurcated end I and lug G.

L designates the spring carrier-teeth that are secured on the cross-bars J. These teeth L are arranged in pairs M, that are formed of a single piece of elastic wire, N, comprising a straight central portion, 0, which is secured to the cross-bar J by staples 1, and has each end coiled round the cross-bar, as at Q, and extended out to form the tooth L. The coils Q, admit of additional elastic movement on the part of the teeth, which have their points It bent slightly, as shown. The teeth L travel between the ribs D as the cross-bars are carried by the chain belts F F at the sides of the elevator.

S designates a number of endless bands that aredisposed longitudinally and are arranged around the cross-bars J, the function of said bandsbeing to retain the grain down against The operation and advantages of my invention are obvious. The two chain belts are driven in the direction shown by the arrows by suitable mechanism connecting them with thedrive-wheel. Thegrainiscarried upwardly 5 by the spring-teeth, which pass between the ribs D and the under side of the elevator mechanism, which latterot course moves upwardly,

combination of the frame A, having inclined 1 they are supported but not connected to the 10 bottom 0, the parallel guiding and supporting strips D, secured longitudinally on the said bottom, the elevating mechanism having the 5 cross-bars J, carrying spring-teeth L, having the bent points R, that engage the bottom 0 and travel one between each twoof said strips D, and the endless bands or cords S, disposed longitudinally around the bars J, by which said bars, as set forth.

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