DECK FOR GRAIN-BINDERS.

SPECIFICATION forming part of Letters Patent No. ,1 dated March 1902- Application filed June 8,1901.

T0 aZZ whom it may concern.-

Be it known that I, ISAAC TROLLEY, a subject of the King of Great Britain, residing in Grantham, county of Lincoln, England, have invented certain new and useful Improvements in Decks for Grain-Binders, of which the following is a specification.

My invention is concerned more especially with that portion of the deck which is adjacent to the canvas rollers, and is designed to produce a deck in which it is impossible for the grain to collect and clog between the deckroller and the deck; and to this end it consists in the employment of an auxiliary deckroller, as will be hereinafter fully described.

Referring to the accompanying sheet of drawings, in which the same reference characters are used to designate identical parts in all the figures, Figure 1 is a perspective View of so much of the deck and its associated mechanism as is necessary to disclose my invention; and Fig. 2 is a sectional view, on an enlarged scale, on the line A A of Fig. 1.

3 is the customary deck, having the needleslot 4 therein extending up to the deck-roller 5, which is of the customary construction and which is journaled in the side pieces 6 and 7 and is connected by the train of gearing 8 with the top roller 9 of the lower canvas 10, so that it will rotate in the same direction as the canvas. The top roller 11 of the upper canvas 12 is of the customary construction. With this customary construction which has hitherto been employed it frequently happened that stalks of grain would fall between the deck-roller 5 and the upper edge of the deck 3, and the heads being too large to pass through the crevice would project upward in the path of the grain, being discharged over the deck-roller 5, and this interferes seriously with the opera- Serial No. 63,693, (No model.)

tion of the machine. This difficulty occurs at the right-hand end of the deck only, and to remedy it I journal the auxiliary deckroller 13 in suitable bearings formed on the deck 3 and in the side piece 7. The result of the employment of this auxiliary deckroller is that in case a suflicient quantity of grain should pass between the main deckroller 5 and the auxiliary deck-roller 13 to clog up and interfere with the feed of the straw over them the wedging of the grain and the forced rotation of the deck-roller 5 will cause the auxiliary deck-roller 13, which is normally stationary or possibly rotating in the'opposite direction, to rotate in the direc tion indicated by the arrow in Fig. 2, in which case the grain will be fed between the rollers 5 and 13 and the clogging thus obviated.

Having described my invention, what I claim as new, and desire to secureby Letters Patent of the United States, is

1. In a device of the class described, the combination with the deck, of the lower can vas, and the deck-roller 13 looselyjournaled between the edge of the deck and the canvas, substantially as and for the purpose described.

2. In a device of the class described, the combination with the top roller, of the lower canvas, the canvas on said roller, of the deckroller 5, gearing between the top roller and the deck-roller, the deck, and the auxiliary deckroller 13 mounted between the deck and the roller 5; substantially as described.

In witness whereof I have hereunto set my hand this 11th day of April, 1901.

ISAAC TROLLEY.
