I Application filed August 27, 1889. Serial No. 321,909. No model.)

To all whom it may concern:

Be it known that I, WILLIAM T. VAIL, a citizen of the United States, residing at Fargo, in the county of Cass and State of North Dakota, have invented a new and useful Imfollowing is a specification.

My invention relates to endless aprons for carrying the grain to the binder, and to vibrating butters for adjusting the butts of grain as it falls upon the platform, in which a vibrating evener or butter operates in conjunction with a single endless apron; and the brating butter, so as to even the butts of grain, and cause it to pass on up to the binder unobstructed; second, to accomplish this by the use of a single apron; and, third, to lessen the friction of the apron on turning the angle where it rises from the platform. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a top view of the machine, showing the platform and carrier-apron with its marginal belts and cross-slats. Fig. 2 is a side elevation of the machine, showing shoe butter and crank and the auxiliary crank connected with the shoe-butter. Fig. 3 is a detached view of the shoe-butter and parts in perspective. Fig. A is a sectional view of the carrier-apron and cross-slats with the anti-friction rollers at the turn of the carrierapron.

Similarletters refer to similar parts throughout the several views.

The platform A, at its junction with the elevator, forming angle a, is provided with shields or guards b b'for the protection of rollers o 0, located immediately under them. The upper fold of the apron passes under these rollers as it turns the angle and rises up the elevator to the binder, thus lessening the friction at that point. These rollers are shortjust long enough to carry the marginal belts d d-and are situated over either end of the driving-roller n, under which the under fold of the apron passes. This apron is provided with belts d d, about one inch in width, running along its margin on either edge and secured firmly thereto. The cross-slats e e e with which the apron is provided terminate at the inner edge of the belts, but are firmly secured to them by means of strips of iron or other material upon the under side of the same, extending under the belts and fastened by rivets uniting the slats, belts, and apron firmly together. This is to prevent the edges from turning up. The apron in other respects is operated like aprons in other machines, and is carried by rollers 0, n, and m, and power may be applied by a gear or pulleys and belts.

B is a vertical crank-shaft, upon which the vibrating shoe-butter is carried and by which it is operated, having pulley J at the top to receive a belt, but may be run by a gear connected with the driving-Wheel.

In order to cause the shoe-butter to describe an eccentric motion, suitable to even the butts of the straw and bring them to a line with the apron, the crank-shaft G is provided, being pivoted to standard 76 at one arm and to the rear end of the vibrating shoe at the other arm. The velocity is to be regulated according to circumstances, so as to bring the butts of the grain to a line before being carried by the apron up the elevator to the binder.

In order to aid the endless apron in carrying the grain up the elevator, the fluted roller 80 P is located over the angle a and at a point where the grain leaves the platform and rises up the elevator, and is operated by a pulley or belt at its rear end and a pulley at the rear end of roller it just below. In connection with fluted roller 1) are fingers s s s s, rising up the elevator over and parallel with the carrier-apron. Pressure upon the fingers is regulated by means of flat spring '0. For the purpose of giving the proper tension to the apron the roller 0 at the top of the elevator is made yielding by sliding bearings controlled by screw-bolts u u at the top of the frame.

I have attempted to provide a mechanism in my invention that will avoid many of the difficulties found in most of the harvesters now in use in getting the cut grain to the binder without clogging and tangling, and will avoid the friction at the angle where the apron turns to run up to the binder, and for this purpose the rollers c c are located so that the belts on the margin of the apron shall freely pass around them. I

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

1. The combination, in a harvester, of an endless carrier-apron provided with endless belts along its border having cross slats or lags which extend only to the inner sides of the marginal belts attached thereto by means of iron or steel plates under each and extending under the endless belts, all firmly united by rivets or bolts, anti-frictionrollers c c and roller n at the angle made by the platform, the elevator, guards b b, rollers 0 and m, tension screw-bolts Mu at the top of the elevator,

substantially as described, and for the purposes set forth and specified.
