, Division C.

the following is a'. full, clear, and exa-ct descrip-` tion of the same, reference being had touthe accompanying drawing, in which- Figure 1 represents a central vertical section 'of a mowing orharvesting machine embracing the improvements of said RAY and SHALT'ERS. Fig..2 represents a top or plan view of the same I machine, the finger-beam being shown, in dotted lines, folded back to the rear; and Fig. 3

represents a front view of the same machine, the linger-beam being shown, in dotted lines, folded up; -and Fig. 4 represents a cross-section just inside of'the shoe, which supports the heel of the linger-beam, for the purpose ofrepresentin g the stiliening-lug on the shoe.

' To enable others skilled in the art to which the said improvements relate, I will proceed -to describe the same lnore in detail.

The nature of the said RAY and SHALTERS improvements, which form the subject-matter of this division of reissue,.consists in, first, a shoe for a hin ged-bar harvesting-machine., .having upwardly-projecting ears to'form-the hinge, and a stilfening--lug cast upon its upper side, in combination with the forked arm or barfor connecting the shoe to th-e'machine, as hereafter described; second, the combination with the drivers seat, in a harvester, of a spiral spring support; and third, a slotted tubular spring support in combination with the drivers seat in al harvester.

In the drawing, the parts marked A. represent the main frame, which vibrates freely upon the axle B, bein g connected thereto by loose bearings aI a. C C are the main l supporting and driving wheels, arranged one upon each end of the axle B, each wheel having an inter lnal gear D attached to its inner side, and into hiell'the small cog or spur-gears E E upon the 'gear-shalt F mesh. Gear-shaft F is supported and turns in bearings b b attached to the bow-shaped gearsupporting frame Gr,y the rear end of which is attached to the axle B,

, and its frontend can vibrate up and down freely, independently of the vibratory motion of the main frame A. Near the center of the gear-shaft F is secured a bevel-gear, H, which meshes into a bevel-gear, H', o n the rear end of the' crank-shaft I, which is supported and turns in bearings rc. c attachedjto the vibrating geanframe G. To the front-endet' the crankshaft lis attached a 4balance-wheel, I', which gives motion vto the pitman-rod J, which is jointed at d, the front part J] ofthe pitman-rodbeing attached to the heel end of the cutter-bar J 2 in theusual manner. K is 'theflnger-beam, its shoe K1 being attachedbyjointseeto the forked plate K2, which is pivoted at f to the'outer endof bar L, the inner end o`f which bar is securely 'fastened to the front end of the gear-vibrating frame G.- A lug, X, is made upon the upper side of the shoe Kl, in addition to the ears which form lthe hinge, by means of which the shoe is attached to the machine. The object of lug X is to stiften the joint of the'bar when it is raised by means of t-he adjustin g-lever, and thus prevent the outer end of the linger-beam from vdropping down toollow, as it otherwise would.

When the bar is raised, which connects the shoe to the machine, the stift'enin g-lu g comes in con.,

'tact with the under side of the bar inside of outer joint thereof,and consequent-ly prevenfl the outer end of the finger-beam from turning downward, although' it is still free to turn npward. As lug X is arranged upon the top of the shoe, near the rear part of the forward hinge-ear and forward-of the line of out, the

cut grass is not liable to lodge thereon and clog the heel end of the cutter, while at the sam'e time free and 4unobstructed space is left between the forks of the connectingrarm. Nor is thelug liable to catch in the earth when the outer end ot' the finger-beam is raised so as to throw the inner edge of the inner shoe upon the ground. To the under side of plate K2 is fastened a supporting-ring, Lf; which is susy tained in a measure, as it turns with the 'plate K2, by a hook, g, fastened to the under side oi the har L. Vhen' the linger-beam is in the working position a pin, h, is insertedinto holes in the bar L and plate K, thereby locking Y those parts together; but when the finger-beam spring support.

in dotted lines, Fig. 2, or forward, pin h is to -be removed.

As, however, the invention or improvements relating to the folding of the finger-beam formk the subject-matter of a separate division of reissueoffeven date hereof; no further description of'the construction and operation of the same is here deemed necessary.

A backwardly-projecting rod, M, is attach ed to the axle, and thus combined with the rear part of the gear-vibrating frame G, having an adj ustable Wei ght, N, to counterpoise or balance the front fof the gear-frame G, the weight of the gearing thereon, and also the heel end of the finger-beam, By moving Weight N nearer to or, further from the axle B, frame G can be balanced so as to cause the shoe which support-s the heel end of the inger-beam to press very lightly on the ground or stubble, and thus reduce the draft of the' machine. O is the drivers seat, kand has combined therewith a spiralsupported at three pointsslotted tubular supports m m 1a retaining the springs and seat in place-the seat O having three guide pieces, 8, which pass through and work in slots tin -the tubular supports m, which are fastened to the top of frame A. Spiralsprings t are at tached to caps m', and also to the ends of guide pieces s, whereby the drivers seat has a spiral spring support, thus relieving, to a great degree, the driver from sudden jars and unpleasant motions of the machine while in operation,

while the seat is held .from turning. To the front of the gear-vibrating frameG is fastened an upwardly-:projecting arm, P, the upper end .of which passes through a mortise or slot in the mainframeA, and is provided with a series of holes, n, whereby the operator can, by inserting a pin through one of the holes above the frame A, adjust the front. of the gear-frame G and heel end of the finger-bearn at any .desired distance above the ground, or so that they will not fall belowagiven point below the front of frame A. This is qnitean advan. tageous arrangement, especially when the inachine is working on ground cut by water-furrows and like depressions in its surface. A lever, Q, is supported o n frame A, the long arm Q extending up in a convenient position to be operated by the -driver from. his seat on the machine. The lower end of lever Q issegment-shaped, and has the upper end of chain In this instance the seat is Rllattached to it, the lower'end'of said chain being attached to frame G, whereby the driver, by drawing the upper end of lever Q back,

can elevate the front of fra-me -G as he may (le- The machine is or may be drawn from sire. the tongue S, attached to or' near the inner corner of frame A. A section of the tongue is shown in Fig..2.

It will be observed that the tongue is at-v f tached to the front of frame A, which is free same frame to which the tongue S is attached,

and consequently is 'controlled by the motion of the tongue, which it serves to counterbal ance. It will also be noticed that the main supporting and driving wheels, with their respective internal gear-wheels,` vibrating geari frame G, main frame A, and its tongue Q, all

have one common axis of motion-the center of axle B.

Having fully described that part of the said RAY and SHALTERssaid invention or improv'ements which forms the subjectmatter of this division of reissue, what is claimed in this division as their invention, and desired to have secured by Letters Patent, is-

1. The combination of the forked connecting-arm,the shoe having itsforward hin ge-ear in front 0f the line of cut, and asti'ening-lug on the shoe andnear to the hinge-ear, whereby the linger-bar is stifened and at the same time a free and unobstructed spaeeis left between the flngerbar. an,d.^connectingarm, snbstan tially as and for the purposes described.

2. The combination, with' the drivers'seat in a harvesting-machine, of a spiral-sprin g support ,and a tubular spring-guide stand, whereby the seatis prevented from turning and the elasticity ofthe seat preserved, for the purposes stated.

3. A slotted tubular-spring support, in combination with the drivers seat and the frame which supportsit in a harvestingmachine.

In testimony whereof I have signed my n name before two subscribing witnesses.
