IMPROVEMENT IN HARVESTER-GEARINGS.
Specification forming part of Letters Patent No. 121,881, dated December 12, 1871 antedated November 30, 1871.
To all whom it 'may concern:
Beitknown that I, J OHN RMANNY, of Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Harvesters, of which the following is a specification, taken in connection with the accompanying drawing, which shows so much only of a harvester as is necessary to illustrate the invention herein claimed, although, in practice, my improvements would be used in connection with a fully organized harvesting-machine.
Figure 1 represents a plan; Fig. 2, a rear elevation; and Fig. 3, a side elevation.
My invention relates to the gearing of a harvester; its object is to change the speed from the slow motion used in reaping to a fast one when mowing, or vice versa 5 and the improvement consists in a novel construction of gearing, consisting of a wheel beveled on both faces and sliding between two corresponding pinions operating gear-wheels of diiferent sizes, as hereinafter set forth. My invention further consists in combining a swinging skeleton eccentric-shipper 'and a detent, with the gearing, as hereinafter set forth.
The main axle A turns freely in the sleeves b b1 of a gear-frame, B, swinging freely round the axle. I usually drive a self-raker by means of a gear mounted on the axle in the space b2 between the sleeves b b1; but such gear is not shown in the drawing, as it constitutes no part of the subject-matter herein claimed. An internally-geared spur-wheel, O, fast on the main axle, drives a spurpinion, c, fast on a shaft, D, sliding endwise, and turning freely in a long box, d, in the gearframe. A gear-wheel, E, beveled on each face, is also mounted on this shaft, and alternately engages with 011e of two bevelpinions f f1. One of these pinions, f, is mounted on the crank-shaft which runs in a long box, g, on the frame, and drives the cutter in the usual way by a crank and pitman. This gearing produces the ordinary motion used in reaping, and ordinarily this motion is suiiciently rapid for mowing. The bevelgears f fl are of equal size. The gear fis mounted on a short shaft carrying a spur-wheel, f2, gearing into a pinion, f3, of similar size, on the crankshaft, to give a faster motion to it. An eccentric skeleton shipping-frame, H, oscillates around a pivot, h, on the gear-frame, being moved by a handle, h. A cam-yoke on the shipper slides in a groove on the collar and moves the shaft endwise. A spring-detent, I, takes into notches on the back of the shipper to lock it in any desired position. Three notches, 1 2 3, are shown in this instance with the shipper locked by its upper notch l, in which position the slow-motion is in gear. When the shipper is locked by the second notch the shaft d has moved inward far enough to clear the gears on either side and the gearing stops. When locked into the lower notch 3 the fast-motion is thrown into gear.
I thus secure a compact, simple, and effective arrangement of devices for changing the speed, for throwing the mechanism into or out of gear, and for securing the steady running of the gearing, all the bearings being long and contained in one frame, by preference of metal.
I claim as my invention- 1. The combination ofthe endwise-moving rotatin g shaft, the wheel mounted on said shaft and beveled on both faces with two bevel-gears of uniform size, mounted 011 independent parallel shafts carrying sp ur-wheels of differing sizes gearing with each other, all these members being constructed and operating as described to vary the speed of the cutters.
2.- The combination of the endwise-movin g shaft, the swinging eccentric skeleton shipper, and its spring-detent, all these members being constructed, arranged, and operating as described.
In testimony whereof I have hereunto subscribed my name.
