l IMPROVEMENT IN HARVESTERS.

The Schedule referred to in these Letters Patent and making part of the same.

To all who-m it mag/'concern Be it` known that we, GRANT T. GooLMAN and CHARLES M. YOUNG, both ot"Goiry,-in-the county of Erie, and State of Pennsylvania, have invented certain new aintusefulImprovements in. Harvesters, of which the following is a full, clear, and exact description.

The invention herein claimed relates to certain improvements on the harvester, for which Letters Patent of the. United States, No. 88,456, were granted to us March 30, 1869. y Y

The first part of our invention. relates to the devices for raising and lowering the cutting apparatus, and

The improvement consists- A First, in' a novel method of combiningamain fran'ie, a hinged coupling-frame, and .a shoeiixed on-the coupling-trarne, with a finger-beam hinged to the shoe, an elbow lever pivoted inthe shoe, and a lifting-leverpivoted on the tongue, and connected with the couplingframe and elbow-lever respectively by independent cords or chains, so arranged that thev first backward movement-of the lever lifts the divider'end of the finger-beam only, and the continuance of this backward movement lifts the heel end of thefinger-beam also. In our former patent, above referred to, the same result was produced in a less perfect manner by a rocking-lever in Athe shoe,and a single lifting-chain or cord.

The object of the next part .of our invention is to render the tongue or draft-frame adjustable, and

Our improvement consists, second, in a novel method of combining the main frame, suspended from the main axle, the couplingf-ranie, thettongue carrying the drivers seat 'and lifting apparatus, and pivoted to the main fra-me with 'a slotted bracket and set-screw on the front of the frame. In our former patent the tongue was rigid, and the inclination of the tongue or frame could not be varied.

Third, the next part of our invention relates to the shipping mechanism, and our improvement consists in a. novel method of combining an oscillating shaft, sliding endwise inits bearings, with shifting-tbrks, loose upon but moving laterally with the shaft, and taking into the collars of the clutch-couplings, by which the mechanismis thrown into or out of gear.

Fourth, our improvement further consists in a novel method of combining a shipping-lever, an oscillating shaft carrying a shitting-fork, cams to move the shaft endwise,and a spring to hold the clutch in gear, unless held out of gear by the driver.

In the accompanyingdrawings all our improvements are shown as embodied in a` machine similar to thai shown in our patent of March 30, 1869, above mentioned. It is obvious, however, that some of ,cur-im` provements may be used without the others, and may also be applied to machines of a construction dilerent from that herein described.

Figure l is a plan or top view of our improved machine, with the covering of the gearing removed.

lf`igure`2 is a view in elevation ofthe same, as seen from the divider side, with the finger-beam in section. Figure 3 is a similar view of the same, as seen from the front.

. Figure 4 is a view of a. portion of the tongue and fran'iedetached, showing their-mode of adjustment.

. In this instance we. have shown two driving-wheels- A A', turning loosely on a common axle, with which they are connected by backing ratchets of any welllinown construction.

The axle turns freelyin bearings on the mainframe B. A coupling-frame, C, is pivoted'y to the main frame, and a` finger-beam, I), is pivoted tothe coupling-frame.

The shoe is made hollow and fixed rigidly on the coupling-frame. The lin ger-beam is secured to a brace, G, pivoted to the coupling-frame and shoe.

A stud, c, is fixed on the pivot of the brace, and an elbow. lever, c', rocks on the same pivot. A toe on the elbow. lever acts on the under side of the `stud to lift the divider end of the finger-beam. y i

A cord or chain, h, passes over a pulley', h', mounted on .the tongue, to a lifting hand-lever, H, also pivoted on the tongue or tongue-plate, and held by a ratchet and pawl of usual form. Either end of the finger-beamis yfree to rise and fall independently of the other, and by the apparatusabove described the dividerend ot' the finger-beam can be raised above the heelend by the hand-lever, and held there by the pawl.`

In order to raise both the coupling-frame andinger# beam, a cord or chain, t, is passed over a. pulley, i', and

connected with the hand-lever H.- This cord i is longer than the other one hl. The result of this -arrangement iStliat when the hand-lever is retracted, the divider end of the finger-beam is rst elevated,

and then, as the movement is continued,ythe couplingu angle of the tongue and frame may thus be regulated. A tool-box, L, which also serves as a foot-rest for the driver, is fastened upon the tongue by a set-screw,

I, passing through a longitudinal slot in the bottom of the box, by which means it may be set nearer to or farther from the drivers seat.

Spur-gears M M' of unequal size are mounted loosely onthe main axle, with which they are locked when the forks enter grooves in this shaft, so that the shaft` while turning independently of the forks moves them eudwse withit.

A shipping-lever, O, pivoted on the main frame, is connected by a link, o, with a crank-wheel, o', on the shaft N.

A cam, p, fixed on the shaft acts on a corresponding cam, p', fixed on the frame, and thus moves the shaft N endw'ise, as it is oscillated by the lever O.

A spring, q, on the shaft N holds the clutch m in gear with the larger pinion M on'the main axle, undess thrown out of gear by the driver, and thus drives the cutters at their most rapid speed. To decrease the motion, the gear M is thrown into action by moving the shaft N endwise. 'lhe spur-wheels M Mgear respectively into corresponding pinions R Rf ou a countershaft, 1, carrying a bevel-wheel, S, which drives a corresponding pinion, s, on a shaft, s, carrying,r an internally-geared spur-wheel, s2, which drives acorrespending pinion on a crank-shaft, T, which drives the cutters hy acrank and pitman, in the usual way. The crank-shaft, it will he observed, is arranged between the gears M M,and is straddled by the shifting forks.

One of the advantages of my mode of arrangingr the gearing and clutch mechanisn'i is, that when unclutched all the gears stop, which would not be the case were the clutches .in the countershaft. I am also enabled to adjust the clutching-forks on their shaft, to comnensate for any wear ofthe clutches.

The other portions ofthe machine having been fully described in our former patent above mentioned, need not be again described here.

What .we claim as our invention, and desire to secure by Letteis Patent, is-

,1. The combination of the main frame, the hinged coupling-frame,r the shoe fixed to the coupling-frame, and the finger-beam hinged to the shoe and frame, the stud, the elbow-lever and its chain It, with the lifting-lever and the chain i, attached to the conplirgframe, the whole constructed for joint operation, substantially as set forth.

2. The combination of the suspended main frame, the couplingfi'ame, the tongue hinged to the frame, the lifting-lever pivoted on the tongue, and the. slotted bracket and set-screw, all constructed and arranged as setforth for joint operation.

lating endwise-lnoving rockshaft, the loose shiftingforks, and the clutches, the combination being and operating substaniall y as set forth.

4. '.lhe combina-tion, substantially as set forth, of a shipping-lever, an oscillating sliding-shaft, carrying shiltingforks, cams to move the shaft endwise, and a spring to hold the clutch in gear.

In testimony whereof, we have hereunto subscribed our names.
