JOSEPH P. BULLOCK, OF MILWAUKEE, WISCONSIN, ASSIGNOR OF TWO- THIRDS TO THE DENNEJIT HARVESTING MACHINE COMPANY, (LIM- ITED,) OF SAME PLACE.

GRAIN-BINDER.

SPECIFICATION forming part of-Letters Patent No. 272,828, dated February 20, 1883.

Application filed November 14, 1882. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH P. BULLooK,

' of Milwaukee, in the county of Milwaukee,

and in the State of Wisconsin, haveinvented certain new and useful Improvementsin Grain- Binder Attachments; and I do hereby declare that the following is a full. clear, and exact description thereof.

My invention relates to grain-binders; and it consists in an attachment to the tripping mechanism by which the amount of grain necessary to trip the binding mechanism into gear is gaged, which will be fully described hereinafter.

1n the drawings, Figure l is a side view of the tripping mechanism embodying my iiivention. Fig. 2 is an inside View of the arm of the compressor-shaft. Fig. 3 is an inside view of my adjusting attachment; and Fig. at is a central longitudinal section on the line arm of Fig. 2 of the arm of the compressorshaft with my attachment in place.

A is the compressor-shalt, and B is a compressor-arm keyed to the shaft,just under the tyer, which latter is not shown.

B is a crank-arm keyed to the compressorshaft, just outside of the frame a. The ou er end of the arm B is wider than its inner end, and has a slot, 1), to receive a hollow lug, c, that projects from the outer face of the plate U. The inner face of the arm B is serrated or provided with ridges 01, while the outer face of the plate 0 has ridges c for engagement with the ridges or serrations 0n the arm B, and is slotted at c to receive a bolt, D, by which the arm and plate are bound together.

E is a yielding rod that connects the cam and gearwheel E" which operates the binderarm and knot-tyer with the tripping and compressor shaft. This rod E' has 2. lug, e, that passes through the hollow lug c, and projects far enough to take a slotted rod or strap. F,

and a washer, f, and this strap connects the compressor with the short arm of the tripping-lever G, the long arm of which, by abutting against a pawl, g, on the clutch of the driving-shaft H, holds the binding mechanism out of gear while the machine is gatherine a bundle. The tripping-lever G has a hub, g, that fits on the shaft of the binderarm, and has a limited play independent of said shaft, so that the short arm of lever G may be depressed by a draft on the strap F far enough to raise its long arm out of contact with the pawl g to trip the machine into ear.

g Operation: Fig. 1 shows the position of the parts when the binding mechanism is out of gear and the compressor-shaft is set to take the largest size of bundles-that is to say, the plate which forms thejunction of the rods E and F is tightened onto the arm B at its highest point. Now, as soon as the bundle which has been collected upon thecompressorarm Bis sufficiently bulky to transmit the force of the packers, the arm B will be depressed and will partially revolve its shaft, causing the arm B to draw upon the strap F and depress the short arm of the trippinglever G until its long arm releases the pawl g, which has held the binding mechanism out of gear. To adjust the compressor for smaller bundles, I have but to loosen the plate 0, raise the arm B, and tighten the plate 0 to it again, for, as the outer end of the plate 0 is always suspended in the same position by the rod E and strap I, the adjustment of the arm B" higher up on the plate 0 will throw the compressor-arm up nearer to the packers, and vice versa.

My present invention is designed as an improvement on the well-known Appleby binder, and therefore I have not deemed it necessary to show or describe the entire operation ofthe binder,but have only shown enough to illustrate my device foradjusting the trip to the size of bundles desired.

WVnat I claim as myinventiomand desire to of October, 1883, in the presence of two Will- IIBSSGS.

, JOSEPH P. BULLOCK.
