I SYLVANUS D. LOGKE, OF JANESVILLE, WISCONSIN.

IMPROVEMENT IN GRAIN-BINDERS..

Specification forming part of Letters Patent No. 57,739, dated September 4, 1866.

To all whom it may concern:

Be it known that I, SvLvANUs D. LooKE, of the city of' Janesville, and county of Rock and State of Wisconsin, have invented a new and useful device for discharging sheaves of grain from the platform oila grain binding apparatus, and which is known as an Improved Sheaf-Discliarging Machine; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanyingdrawings making a part of this speciiication, like parts being referred to by like characters in each iigure.

The nature oi" my invention consists, first, in discharging sheaves or bundles of grain from the plaliorm of a grain-binding ma chine 0r harvester endwise, or in the direction of and corresponding with the line of the bundle, by means of a broad pad, or other mechan- I ical device presenting a broad, llattened ysurface, forced by power taken from a grain-binding machine or harvester against the end of the bundle, second, in increasing orlessening at pleasure the stroke ot' the discharging device ot' a sheaffdischarging machine by means of an adjustable crank; third, in communieating motion to a sheaf-discharging device by means ofa pin in or a cam on a cylinder or shaft of a grain-binding machine, working in connection with the pitman ofa sheatdscharging machine; fourth, in returning the several parts of a sheaf-discharging machine to a position ready to receive a sheaf or bundle for discharge by means of' a reacting` spring, couliterpoise, or equivalent device, when attached to and made part of a sheaf-discharging machine.

'Io enable others skilled in the mechanic arts to construct and operate my invention, I will refer to the accompanying drawings, in which- Figure l is an elevationof the machine. Fig. 2 is a top view of the same. Fig. 3 is an elevation seen at rightlangles to Fig. 1. Fig. 4 shows the end of a cylinder belonging to a grain-binding apparatus, which I here introduce to show one mode of communicating power or motion to the sheaf-discharging device.

J, Figs. 2 and 3, is a standard, which is attached to the frame-work of a grain-binding standard .I for the shal't A. F is an arm con` nected with the shaft A, on the end of which is a broad pad or attened head, Y, which, when the machine is in operation, is pressed against the end ot' the bundle, discharging it endwise from the binding apparatus. The crank t, connected with the pitman O, Figs. 1, 2, 3, and 4, is for the purpose of increasing or lessening the stroke of the head Y, made adjustable as to length by means of a slot in the crank, in which is inserted the bolt u, or compensating device, as a recess in or a sleeve on the crank. F is a spiral spring, which, or its equivalent as a counterpoise, is employed to return the pad to the position shown in the drawings after a sheat has been discharged from the binding-plati`orm- I, in Figs. 3 and 4, is a projection on the pitman O. In place of this projection a pin in the pitman, or the pitman itself, by an abrupt deflection at the proper point, will serve as well. C is a part of the binding apparatus, through which the pitman O takes bearing. D is a pin projecting from the end of the cylinder B, Figs. l and 4. A pin in the cylinder-shaft, or a cam on the shaft, may be used in the place ofthe pin D. R is a part of the frame-work of the binding apparatus. X is a metallic grain-guard belonging to the same.' When the cylinder `B is in motion the pin D comes in contact with the projection m on the pitman O, carrying itdown, and thus moving the head Y transversely across the bindingplatorm i, in the direction indicated by the dotted lines Gr G, Fig. 3,' at the same time carrying the shear' along with it, and coiling` up the shaft-spring E, which, after the pin D passes oli', the projection m on the pitman 0 carries back the head F to the position sllown in the drawings.

What I claim as new, and which I desire to secure by Letters Patent, is-

1. The combination and arrangement ofthe part C, pitman O, constructed substantially as described, crank t, shaft A, standard J, and head Y, when the whole are constructed, arranged, and used substantially as and for the purpose set forth.

2. The combination and arrangement of the lpart C, -pitman O, constructed substantially as described, shaft A, standard J, head Y, .Y, when the whole are constructed, arranged, and shaft-spring F, when the whole are eonand used substantially as and for the purposes structed, arranged, and used substantially as set forth. and for the purpose set forth.

3. The combination and arrangement of the Witnesses: part C, pitman O, projection m, cylinder B, pin D, shaft A, crank t, standard J, and head s. D. LOGKE.
