JOSEPH P. BULLOCK, MILWAUKEE, WISCONSIN, ASSIGNOR OF TWO- THIRDS TO DENNET'I HARVESTING MACHINE COMPANY, (LIMliTED,) OF

SAME PLACE.

GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 274,883, dated March 27', 1883.

Application filed January 29, 1887. (No model.)

To all whom it may concern Beit known that I, JOSEPH P. BULLooK. of Milwaukee, in the county of Milwaukee and in the State of Wisconsin, have invented certain new and usei'ulImprovementsin Grain-Binders; and 1 do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to automatic g ainhinders; and it consists in a device for starting the binder by pressure of the grain on the packers, as will be fully described hereinafter. In the drawings, Figure l is a perspective 'view of my lllVB'liiOl],llld Fig. 2 is a side view.

A is the usual compressor-shaft, and in this instance it is also the tripper-shat't; B, the

trip-arm or compressor.

O U are the packers, which are connected to extensions of the compressor B by links c c.

D is the binder-arm.

a is a crank-arm on the end of shaft A, and this arm is connected by a rod, a, to a lever pivoted on the frame and operated by a camgroove in the tyer-wheel, as is usual in this class of binders, whilea link, a is designed to conmeet the compressorshaft with the clutchtripping mechanism of the Appleby binder.

The packers are worked by a crank-shaft, E, and until a bundle of sufficient size has been collectedfthey will work t'reelywithout affecting the arm or-compressor B; but as soon as a gavel has been collected the resistance it atfords will hold back the upper end of one of the packers, and cause its lowerend to thrust upward upon one of the links a hard enough to cause it to lift upon the extension of the compressor and turn the crank-shaft outward, and

thus trip the machine, and thus if the cords should catch and not permit the grain to reach the compressor the tripping will still he accomplished.

I have found it most convenient to attach the links to extensions of the compressor; but I may key ears to the shaft A, which will fully answer the purpose of the extensions b b of the com pressor.

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

l. The combination of the rocking compressor-shaft carrying the compressor-arm with the packers, the latter connected with the compressor-shaft by linksvat-tached to the heels of the packers-,and to cars projecting from the compressor-arms, whereby the resistance of the grain to the packers rocksthe com- December, 1882, in the presence of .two wit-- nesses.
