IMPROVEMENT IN GRAIN-BINDERS.

Specification forming part of Letters Patent No. 196,775, dated November 6, 1877 application led May 12,

To allwhom it may concern: a l

Be it known that I, CHARLES B. WITHIN@- 'i0N, of Janesville, in the county of Rock and State of Wisconsimhave invented certain new and useful Improvements in Grain-Bindin g cation: n

. My invention relates to that class of autowith wire by a binding-arm, and the ends of the wire united by twisting them between the teeth on the periphery of a rotating twister, in contradistinction to the class in which two wires are twisted in the Same slot near the axis of the twister.

In twisters of the class to which my invention more especially relates, it is necessary that one end of the wire should be carried around to the'back of the twister, so as to be opposite the other end when the twisting begins.

The object of my invention is to insure the positive entrance of the wire into the slot of the twister, irrespective of the size of the gavel or the condition of the grain, which end I attain by forcing the wire into the slot of the twister or binding-head by a spring push-rod or wire-inserting mechanism. This end may be attained either by moving the twister and binding-head up to the wire-inserting mechanism, or by moving the wire-inserting mechanism up to the twisting-head.

The subject-matter claimed will hereinafter specifically be designated.

The accompanying drawings represent my improvements as applied to the well-known Withington binder, built by C. H. -t L. J. McCormick, of Chicago, Illinois, in which the twister and binding-arm reciprocate horizontally in a straight line; but, obviously, my improvements may be adapted to machines of a different construction-such, for instance, as those moving in a vertical or horizontal circular path.

Figure 1 represents a front elevation of so much of my improved apparatus as is necessary to illustrate the subject-matter herein claimed, with the framing partially broken away, and the binder-head partly in section,

on the line 2 2 of Fig. 2, to show its details of construction more clearly. Fig. 2 represents a plan or top view of the binding-head and wire-inserting device, in the relative attitudes they assume when. forcing the wire into thev twister; and Fig. 3, a similar view vof the Same after the wire has been inserted, with the wireinserter moved to one side out of the way of the Aincoming wire. Fig. 4 represents a side elevation of the wire-inserting apparatus in section, on the line 1 1 of Fig. 2.

The description of the machine will be conned to the parts more immediately relating to the Subject-matter herein claimed, the general organization and operation of the machine being shown and described in Letters Patent granted to me March 7, 1876, as No. 174,454, and January 9, 1877, as No. 186,186, and in the application for Letters Patent of Lambert Erpelding, filed January 27, 1877.

The mechanism is mounted upon a bindingframe, A. A Abinding -head, B, reciprocates upon ways on said frame, being driven by a chain and sprocket wheels from a drivingshaft, C. In this instance the wire-inserting apparatus is shown as composed of a bar or plate, l), connected at its rear end by a pivot, d, with a spring rod or piston, E, movable'endwise in bearings e upon the binding-frame, and encircled by a spiral sprin g, c', which tends to keep the device always .thrust forward in the position shown -in Figs. 1, 2, and 4. In addition to the endwise movement of which the wire-inserting plate Dis thus rendered capable, it has a lateral s winging motion around pivot d, the extent of which motion is regulated by a diagonal slot in the plate, in which the pin d', fixed on the frame, works.

The operation of the apparatus is as follows: After binding a gavel, the Wire-carrying arm F rises and moves backward, leaving one end of the wire in the twister-slot in front of the twisting-pinion. The grain to be bound then passes in upon the binding-platform. As the binding mechanism moves forward to compress the gavel, the wire in the twister-pinion abuts against the square end of the wire-inserting plate D, and is, consequently, positively pressed into the twister, just vat the moment it makes its half-turn, which carries the wire to the back of` the twister.: Bythe time this--has-beendone, the parts assume the relation shown in Fig. 3. 'lfhe continued forward movement of the binding mechanism forces the wire-inserting` plate D backward and to one side into the position. shown in Eig. 3,. where it is held during `the descent ofthe wire# carrying arm, which bringsV the other end-fof' the wire into the slot of the binding-head or twister, in doin g which it slides along the sloping or wedge-shaped inner edge of the wireinserting plate D. As the binding mechanism is retracted the two ends of the wire are twisted together and cut, and the bundle is discharged in the usual way. The moment the binding-head retracts, the wire-inserting plate is thrown forward into its normal position by its actuatingsprng, and the operation above described is repeated.

My invention is adapted for uselwith either:

one or two binding-wires.

What I-claim as my invention, and desire to y secure by Letters Patent, is-

1. A` wire-inserting device actuated by a spring, which forces the wvire into the twister as the latter makes-its half-turn, to bring the wire to the back of the binding-head, substantially as hereinbefore set forth..

2. The combination, substantiallyfas herein-AY before set forth, of an intermittently-rotating twistenpinion, a wire-carrying arm, and awireinserting device, actuated by a spring, whereby the wire .is forced into `the twister. bythe f wire-inserting device, which then lmakes way' for the passage of the wirecarrying arm.

3. The combination, substantially as hereinbefore set` forth, .y of a reciprocating bindingarm and twister, with `an endwise-moving, laterally-swinging wire-inserting device7 mounted upon a xed portion of the bindingfframe, whereby the wire-inserting device is actuated `by the movement of the binding-head.

4. A wire-inserting device consisting ofthe combination, substantially as hereinbefore set forth, ofthe endwise-moving-3springrod, the `wire-inserting plate or `bar pivotedthereom.
