Specification of Letters Patent.

Patented J an. 21, 1913..

Application filed September 18, 1912. Serial No. 720,707.

To aZZ whom it may concern:

lie it known that I, l'VALT-nn AN SON HILL, a citizen of the United States of America, and a resident of Enderlin, in the county of Ransom and State of North Dakota, have invented certain new and useful Improve ments in Independent Release Attachments for Self-Binder Trips, whereof the following is a complete specification.

This invention relates to an independent trip release for the binder mechanism of a self-binding harvester, operative independently of the automatic trip of the binding operation and at the will of the driver without dismounting from the seat and without stoppage of the machine.

In. self-bindingharvesters in common use, the delivery mechanism often becomes choked by damp or irregular grain, requiring the driver to halt his team, dismount from the seat and release the binder trip by hand.

The object of this invention is to provide a simple and effective device of this character which can be applied to harvesters already in use, which may be operated by the hand or foot of the driver, which will not interfere with the working parts of the self binding harvesters in operation, and which is automatically extensible and con tractible in unison with the binder head.

Figure 1 of the accompanying drawings represents a perspective view of parts of a grain binder provided with a trip release attachment embodying one form of this invention. Fig. 2 represents a plan partly in section of the sliding pivotal connection between a crank of the release mechanism and the outer ends of the connecting rods of the hand and foot levers. Fig. 3 represents on a larger scale a side elevation of a part of this trip release mechanism. Fig. a represents a side elevation of the hand and foot release levers and the immediate connections of the foot lever. Fig. 5 represents on a smaller scale a perspective view of parts of an automatic tripping mechanism with which this independent trip release is connected.

Corresponding reference characters indicate the same parts in the different figures,

numbers being used for parts constituting this improved attachment and letters for old parts of the automatic trip mechanism to which this attachment is applied.

A crank arm 10 is fixed to the cranked trip rod A of an ordinary or known. automatic trip mechanism by a clamp 11 or any suitable means and provided at its outer end with a crank pin 12. An extensible and contractible or telescopic crank shaft 30 is disposed longitudinally of the binder frame at the outer side thereof. This crank shaft is composed of two freely intersliding members 31 and 32, which permit the automatic lengthening and shortening thereof. The parts of the members where they mterlap are square or angular in cross section or otherwise constructed so as to prevent the turning of one member on the other. The member 31 is provided at its outer end with a crank 33 and the member 32 is provided at its outer end'with a crank 34: having a duplex crank pin 35 which projects at opposite sides of the crank arm. This crank may be screwthreaded at its opposite ends and provided with nuts or other cotter fastenings 36 and 37. The far member 31 is supported at its outer end in a bracket 38 secured to the movable part B of the binder frame at one side thereof and the near member is supported at its outer end in a bracket 39 secured to the fixed part C of said frame at the rear end thereof, the inner ends of these members having a sliding support on each other. Any suitable sliding support may be employed. In the form shown the member 32 has an offset portion 32 connected at its inner end with the body by a shoulder 32 and provided at its outer end with a lateral lug 3n opposite said shoulder 32". The shoulder 32 and lug 32 are provided with angular bearings disposed in alinement. The body of the member 31 is angular in cross section and slides freely in said bearings, its inner end overlapping the body of the member 32. A connecting rod 20 connects the crank 10 with the crank 33. This connecting rod is provided with a slot 21 at its outer end which is loosely engaged by the crank pin of the crank 10. A hand lever 50 is pivoted at its lower end to a bracket 51 attached to the underside of the binder deck and is movable in a loop 52 attached to said binder deck. A connecting rod 40 is pivoted at its inner end to said lever and provided at its outer end with a slot 4-1 which is loosely engaged by one end of the duplex crank pin 35 of the crank 34.

An elbow bracket comprising a vertical arm 60, a horizontal lateral arm 60 and a horizontal rearward extension (30 is secured to the main frame and a horizontal bell crank lever is pivoted thereon.- A connecting rod i5 is pivoted at its inner end to one arm of said bell crank lever and provided at its outer end with a slot 46 which is loosely engaged by the other end of the duplex crank pin 35 of the crank 34. The same arm of the horizontal bell crank lever 65 is provided with a lateral stud 66 which slides at its outer end in a guide hole 61 in the rearward extension 60 of the bracket 60 and an expansive spring 67 on said stud tends to hold in outward position the arm of the bell crank lever 65 to which said connecting rod is secured. The bracket 60 is also provided with a stop 63 which is engaged by the other arm of the bell crank 65 and arrests said lever at the end of its backward movement. A bracket 80 is also disposed on the main frame in front of the bracket 60 and a vertically disposed bell crank foot lever 85 is journaled in said bracket. A link connects the upward arm 86 of the foot lever 85 with the outer arm of the horizontal bell crank lever 65.

In the operation of this attachment, whenever for any reason the driver finds it necessary to release the binding mechanism before the time of releasing under the usual automatic action of the trip mechanism, he depresses the foot lever 85 or pulls the hand lever 50 as may be most convenient at the moment. In either case the telescopic crank shaft 30 is oscillated a sufficient distance to turn the trip rod A and cause the crank D at its outer end to lift the usual stop arm E and release the dog F of the shipping pinion of the delivery mechanism. The slot of the connecting rod 20 permits the free play of the trip rod A under the action of the ordinary automatic trip mechanism, whereof the ordinary crank arm Gr on said trip rod constitutes a part. The slots in the connecting rods 40 and 45 for the hand and foot levers respectively permit the telescopic crank shaft 30 to turn without interference of the other when either of said levers is actuated.

I claim as my invention:

1. An independent release attachment for self-binder trips comprising a crank shaft composed of intersliding relatively nonrotating sections attachable respectively to stationary and movable members of the binder frame, an actuating lever adjacent to the drivers seat, connecting mechanism between said crank shaft and actuating lever, and a connecting means between said crank shaft and the automatic binder trip mechanism, said connecting means permitting the free play of said mechanism under the automatic trip and being operative to transmit motion from said crank shaft to Copies of this patent may be obtained for said mechanism for the independent release thereof.

2. An independent release attachment for self-binder trips comprising a crank shaft composed of intersliding sections, one of said sections having an offset provided with lateral lugs having angular bearings, the other section being constructed to slide in said bearings, an actuating lever adjacent to the drivers seat, connecting mechanism between said crank shaft and actuating lever, and a connecting means between said crank shaft and the automatic binder trip mechanism, said connecting means permitting the free play of said mechanism under the automatic trip and being operative to transmit motion from said crank shaft to said mechanism for the independent release thereof.
