Letters Patent No. 103,970, dated June 7, 1870.

IMPROVEMENT IN REELS FOR HARVE SIERS.

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

the required adjustment of the reel, while the machine:

is at work in the field, to adapt it to the varying condition of the grain operated upon, as hereinafter set forth.

In the drawing- -A represents a base-plate or casting of any suitable form to adapt it to that part of the machine-frame, finger-bar, or platform, to which it may be desired to secure it, and provided with uprights or lugs a a, in ligearings, in which is mounted a horizontal rock-shaft,

G is a reel-post, provided with a horizontal base or flange, G, which is connected by a vertical pivot, c, to the horizontal roekshaft B.

To the upper end of post 0 is secured a horizontal bar or frame-piece, D, which projects inward or on the main-frame side of upright reel-frame or -post, and is provided with a study-shaft, on which is mounted a loose pulley, E, around which the reel-driving belt passes, as hereinafter explained.

F is a horizontal cross-head or reel-bearer, made in the form shown in the drawing, or in other suitable form for the purpose. I prefer to make said crosshead in a single casting of light angular or flanged form, whereby the requisite strength is obtained with the least possible weight of material.

Said cross-head is provided, at its opposite end, with hearings f, for the reel-shaft, and, at or near midway of its length,vwith vertical sleeves or clas-ps G, adapted to receive upright G, and to slide freelyiup and down thereon.

These sleeves or elasps have avertical rack, H, firmlysecured to them on' the side of the standard opposite the yoke, said rack engaging with and being operated by a pinion, h, in a vertical directiomand carrying the cross-head F with it in its vertical movement.

The shaft of pinion It has its hearings in a box, I, secured to the reel-standard, and is connected at one end, by a tumbling or universal joint, to one end of a crank-shaft, J.

The opposite end of said shaft is mounted in a sleeve, K, connected by a horizontal pivot with an upright lever, L, and provided with recessed arms or hooksj', with which the pivoted crank-arm J is made to engage for holding said shaft and the pinion-rack, and cross-heads operated thereby, at any desired pointof adjustment.

The lever L is located in convenient relation to the drivers seat M, so as to be operated by the driver sitting thereon, and is pivoted at its lower end in upright standard N n, on a base-plate or casting, N. The upright standard N is extended in width at its top, and is provhledwith a curved rack, in which a spring pawl, Z, operated by a bell-crank lever, 1 connected with the lever L, engages to hold said lever at any desired adjustment.

A spring, 2*, serves to hold thepawl engaged with the rack, when not thrownont by the hand of the attendant in grasping the top of the lever, together with bell-crank lever, for operating the same.

From the foregoing description it will be seen that, when it is desired to raise or lower the reel, the attendant simply releases-the pivoted crank-arm J from its holding-socket, or books and rotates the same, together with the shaft and pinion connected therewith, thereby moving the vertical rack H, and the cross-head connected thereto, and carrying the reel-shaft, until the desired height of .the reel 'is secured, when the crank-arm is looked, as before;

In adjusting the reel back and forth horizontally, the shaft J serves merely as a connecting-rod or link between the reel and lever, and, by releasing the. lat ter, the attendant is enabled to set the reel. forward or back, as may be desired.

A link or rod, '0, forked at one end, and embracing the foot of the reel-standard, is pivoted horizontally to said standard, and extends to a point near the driverfs seat, where it is connected adjustably, by a slot and thumb-screw or otherwise, to a transversely adj ustable ,plate, 0.

The plate O" is secured to the drivers foot-board, or other convenient support within reach of the driver on his seat, and is provided with a slot at 0, and thumb-screw 1;, or with other suitable means for permitting its adjustment transversely of the machine.

By the lateral movement of said plate, or the end of the rod or bar 0, connected thereto, the reelpost D i is swung upon its vertical pivot, and the reel-shaft is thereby caused to diverge either forward or backward,

as may be required, and to any desired extent from the line parallel with the fingenbar, represented at P.

The adjustment of .the reel is designed to adapt said reel to grain which leans either toward or away from the main frame, and enables the driver to readily set the reel so as to cause the heaters to strike underneath and raise such grain, and to present it properly to the action of the cutters.

The arrangement of means for driving the reel permits the several adjustments above described, and is as follows:

A pulley, E, is mounted upon a shaft, arranged in AND line with the horizontal pivot at the foot of the reelpost, and mounted upon the same part of the machine, so as to maintain a fixed relation thereto. Said pulley may be operated or driven hyany suitable connection with the main driving-wheels or axle, and is provided with a band,whieh passes upon opposite sides of a pulley, E, on the end of the reel-shaft G, and over the loose pulley E, on arm D of the reel-standard, above referred to.

Gnide-pulleysor sheaves e e, mounted on studs e, on opposite sides of the pulley E, on an arm or support attached to the sliding yoke, serve to confine the belt to any required extent of surface of said pulley, to insure the rotation of said pulley, and of the reelshaft with which it is connected, and also permit the vertical adjustment of the reel without changing the tension of the band.

By this arrangement of the driving-pulley E, relative to the pivotof the reel-post O,-the pulleys E E are maintained at a uniform distance apart, and the reel-shaft, with its pulley E may be vmoved up or down to any desired intermediate point, without affecting the tension of the driving-belt.

Having now described my invention,-

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

1. The single pivoted reel-post G, in combination with a lever and link, arranged substantially as described, whereby the driver, in his seat on the machine,

can control the horizontal or forward and backward adjustment of the reel.

2. The reel-post or standard,providedwith the two pivots, arranged at right angles to each other, the one vertical and the other horizontal.

3. The cross-head or yoke F, in combination with rack H, pinion h, and a device for operating said pinion, to adjust the reel vertically.

4. The eross-head or yoke F, provided with the rack H, in combination with pinion h and tumbling-shaft J, for adjusting the reel, as described.

5. The sleeve K, in combination with a standard for supporting the same, and devices connecting said sleeve with the standard and with the reel, substantially in the manner described, so that the reel may be adjusted as set forth.

.6. The pivoted crank-arm J, in combination with hooks or sockets j, for holding the reel at any desired point of adjustment.

7. The swiveling reel-post, in combination with red or link 0 and slide 0, for adjusting the angle of the reel, relative to the cutting apparatus, as described.

8. The arrangement of guide-pulleys e c with the driving belt and the driver-pulley E whereby the required vertical adjustmentof the reel may be effected without varying the tension of the driving-belt.
