IMPROVEMENT IN HARVESTING-MACHINES.

Specification forming part of Letters Patent No. 16,131, dated November 25, 1856; Reissue No.1,203, dated June 25, 1861; Reissue No. l ,6l 5, dated February 2,1864.

Division 1 B.

To all whom t may concern:

Be it known that I, WILLIAM N. WHITELEY, Jr., of Springfield, in ,the countyof Clarke and State of Ohio, have invented certain new and useful Improvements in Harvesting-ll/Iaollines; and I do hereby declare that the same are described and represented iu the following speciication and drawings.

The nature of my invention and improvements in harvesting-machines consists in providing an automatic'rake which has its outer end move faster over the platform than'its inner, with suitable mechanism to enable the driver, on his seat, to lock the crank which drives the rake to its shaft or release it therefrom, so as to rake the platform more Ior less often and make the gavels of a proper size for binding into sheaves where the grain is thin on the ground.

To enable other skilled in the art to make and use my improvements claimed in this patent, I will proceed to describe them, referring by figures and letters to .the accompanying drawings, in which the same letters indicatev like parts in each of the figures.

Figure 1 is a perspective view of a harvesting-machine with my improvements. Fig.-2is

a perspective view of one of the sector-plates (each of which carries an adjustable box in which the axle of the main groundand driving wheel turns) and its center studor bearin g detached. Fig. 3 is a perspective view of the pinion-shaft, pinions, clutch-pin, and shipper. Fig. 4 is a vertical section through the center of the drivin g-wheel at a right angle to its axle. Fig. 5 is a vertical longitudinal section inside of theydriving-wheel, illustrating the vibrating adjustable sector-plates and adjustable axleboxes. Fig. 6 is a partial duplication of Fig.

5, illustrating by red and black lines the ch an ge,

of piuions by sliding they master-wheel axleboxes. Fig. 7 is a section of the main ground and driving wheel cut parallel to its axle. Fig. 8 is a perspective view of the front connectingbar of the frame. Fig. 9 is a transverse vertical section on 'the line x a' of Fig. 4. Fig. 1() are top and bottom views, in perspective, of the rear portion of the tongue and its retainingstirrup. Fig. 11 is an elevation ofthe side of the rake arch or guide and balance-lever. Fig.

12 is an elevation and vertical section of the grain-wheel.

The object of my improvements as claimed in this'patent isto enable the driver (where the grain is too thin to form a sheaf or gavel with a sin gle revolution ofthe ground-Wheel) to stop the automatic rake and hold it out of the way V of the falling grain untilsufticient has accumulated on the platform to make a sheaf, and then to start the rake and rake it oli" and stop the rake again withoutv leaving his seat or stopping the machine.

That end of th'e finger-bar, cutter-bar, platform,and automatic rake which isat the right When standing behind the machine I call the inner ends, and those at the left outer ends. v t

The tongue, main frame, main ground and driving wheel, cutting apparatus, driving mechanism, divider, grain-wheel, and drivers seat may be made and connected as shown in the drawings.

The inner end of the finger-bar G is fastened to, the under side of the main frame, and the platform B2 is arranged directly behind the linger-bar G, and its outer end is made wider than the inner end, and the rear end of the divider I is curved-inward to about correspond With the sweep of the end of the rake F.

The rake arch -or guide Kis made in the form shown in Fig. 11 and fastened to the finger-bar and platform. This rake-guide is curved, as shown in Fig. 1, to correspond with y thev sweep of the rake-teeth f2. The forward part of the guide K is parallel with the platform, and its rear part rises in the arcof a eircle to lift the rake as the gavel falls from the platform. Y

The rake F is hinged at fi, with a kind of universal joiut,to the bar A2 of the main frame, so as to be rocked freely by the pitman m, which operates it. The pitman m is inserted in a mortis'e in the rake and fastened by the pin c2, so as to vibrate horizontally, while it rocks the rake and vibrates the teeth slightly. The pitman m connects the rake to the crank l, which is fitted to turn freely on the groundwheel shaft D, and is provided with a score, which embraces the clutch-pin x in the outer end ofthe shaft D and lock-s the crank l to the shaft, as shown in Fig. 1. This crank lis y pressed against the clutch-pin by the coiled spring arranged on the shaft D between the nox g and the crank. The hub of the crank Z has a groove around it for the shipper-lever P, which vibrates on, a stud fastened to the bar A of themain frame, so that-the driver, on the grain as it is brought forward, I'makea lever,

P, Figs. 4 and 5, with a fork at one end and weight at the other, and hang it on a pin in the guide K, so as to vibrate freely, the weight P' holding the-fork up when it is released by the rake. The vibrations of the lever P are checked by the stop X on the guide K.

From the above description it will be apparent that while the crank Z remains locked to its shaft the rake Awill sweep the platform at every revolution of the ground-wheel, and

consequently the gavels will only contain the grain gathered at one revolution of the groundwheel, which is. all right when the grain is large and thick enoughA to make a sheaf with a single revolution of the ground-wheel; but if the grain is light and thin, so as to require two or more revolutions of the ground-'Wheel to make a sheaf, the binders would have to carry` one gavel to another and put two together to make a sheaf; but with the improvements described the driver can stop the rake -while the ground-wheel makes one-half, or a whole, or two or more revolutions, and allow grain enough to accumulate on the platform for a sheaf, and then rake it olf, and thus save ythe binders the additional labor of carrying .one gavel to another and putting two together to make a sheaf, for when-the rake has swept a gavel from the platform and is on the rear part of its guide the driver pushes the lever P withrhis foot and draws theY crank from its clutch-pin and rstops the rake, which rests on its guide, out of the way of the falling grain, until grain enough has been gathered on the platform to makea sheaf, when the drivery starts'the rake, which depressed the lever P as it moved backward and passed over the short prong of the lever, Awhich lever lifts the rake up above the falling grain as it is `carried forward, and the teeth of the rake drop into the butts of the grain behind the cutter-bar and sweep the gavel sidewise and backward off of the platform out ofthe path of the team in cutting the next swath. As the 'l rake was carried forward it passed out of the lever P, when it fell into the butts ofthe grain, and the weight P raised the lever ready to be depressed again as the rake passes back in raking the gavel from the platform.

I believe I have described .and represented my improvements in harvesters, so as to enable any person skilled in the art to make and use them without further invention or experiment. I will now state what I desire to secure by Letters Patent, to wit:

In combination with a harvesters platform which is behind its cutting apparatus, an automatic rake having its outer end moved faster over said platform than its inner by a crank and pitman, providing said crank with suitable mechanism, so that the driver, on his seat,"can lock the crank to or release it from its shaft or drivin'g mechanism, so as to make the rake removeV the gavels from the platform more or less often while the machine is in mo tion, and make the gavels a proper size for binding into sheaves where the grain is thin on the ground.
