GRAIN-BINDER} SPECIFICATION x'orming part of Letters Patent No. 315,288, dated April 7, 1885. Application filed September 22, 181 53. (No model.)

T0 at whom it may concern Be it known that I, PLINY F. HODGES, a citizen of the United States, residing at Chicago,

in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Grain-Binders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to that class of selfbinding harvesting machines in which the binding wire or cord is applied around the bundles ofgrainbya so-called binding-arm, and from which the bound bundles of grain are ejected by a so-called discharging-arm, one or more, operating from above the bundlesupporting platform, or so-called binder-table, as distinguished from that class of machines in which the discharging-arm operates from below through a slot in the binder-table.

My improvement, designed for machines in which is used an orbitally-moving bindingarm operating from above the binder-table,

consists in so combining a discharging-arm, one or more, with such binding-arm that an orbital movement is also imparted to the discharging-arm.

In order that my invention may be clearly understood, I will describe it as applied to a machine operating with a binding-arm substantially such as described in United States Letters Patent No. 255,985, granted to me on the 4th day of April, A. D. 1882. t

Figure l is a plan view of so much of a selfbinding harvesting-machine as is required to illustrate my invention in connection with said patented binding-arm. Fig. 2 is an end elevation of the same.

The same letters of reference indicate identical parts in both the figures.

The binding-arm A is pivoted to a crankpin, a, on the crank-disk B, fixed to the extreme outer end of the binder-shaft B, and is constructed with a rear extension, A, which is connected by a link, A to an oscillating lever, A This lever A is fulcrumed at a to a bracket-arm, G on the tubular overhanging arm 0, which supports the binder-shaft,

and it is provided with a laterally-projecting stud carrying an anti-friction roller, a which enters a cam-groove in the back of crank-disk B. The cam-groove (shown in dotted lines in Fig. 2) oscillates lever Aiwhich, through link A and the rear extension, A, rocks the bindingarm on crank-pin a as the latter carries it around in the rotation of disk B, so that the binding-arm moves in the manner described in my aforesaid patent. Y The discharger-shaft D is journaled in bracket-arms C and 0, projecting from the standardG andtubular overhanging arm G, respectively, and is driven in thisinstance by a train of spur-wheels, c c c", from the binder-shaft. I employ two orbitally-moving discharging-arms, E and E,

respectively pivoted to the cranks d and d of the discharger-shaft, so that they are on opposite sides of the binding-arm. Each discharging-arm is constructed with an extension or stem (marked e and e) respectively. Thesestems e and 6' pass through eyes 6 and c on the opposite ends of the loose pivot-pin a, which connects link A and lever A I It will be readily observed that in consequence of the described connections of the discharging-arms they will travel in an orbitpath, so as to maintain aposition substantially vertical to the binder-table in sweeping a bundle of grain from it, fected by known means other than those described, although, when used in connection with my aforesaid patented binding -arm, I prefer to combine the discharging-armsthere with in the manner described for the sake of simplicity.

In the machine illustrated (in part) the grain delivered from the grain-platform (only the delivery end F of which is shown) is packed against the binding cord or wire a: by packers G, which are the last teeth on the toothed carrying-bars G, by which the grain is moved across the grain-platform toward the binder- This action may be efv table, and which have a compound recipro- I higher speed than the packers G, swings the grain in the direction indicated by the arrow This butt-hastener, which is driven at a in Fig. l,so that in effect the grain is moved ing-arm the stem of which is controlled by 10 in an obliquely-rearward direction in the act the pivot-pin connecting said oscillating lever of packing it into a bundle or sheaf. and link.
