HARVESTER REEL. v No. 338,957. Patented Mar. 30,1886.

LEWIS HALL, OF WORTH, WVOODFORD COUNTY, ILLINOIS.

HARVESTER-REEL.

SPECIFICATION forming part of Letters Patent No. 338,957, dated March 30, 1886.

Application filed February 9 1885.

To aZZ whom it may concern:

Be it known that I, LEWIs HALL, of \Vorth township, in the county of Voodford, in the State of Illinois, have invented an Improved Harvester-Reel; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed drawings, making a part of this specification, in which like letters of reference refer to like parts, and in which- Figure 1 represents a perspective view of a harvester platform, showing the invention; and Fig. 2, a side elevation of my invention, showing also the path of the reel-bat.

This invention relates to reels for throwing the grain over against the sickle and upon the platform in reapers or harvesters.

My device consists, essentially, of a single reel-bat supported from and given the required motion by vibratory reciprocating bars.

The means for operating the bars consists of a shaft having cranks giving a circular motion to the ends of the bars opposite to the reel-bat, and sliding supports for the bars.

In the drawings, P is the platform of a reaper or harvester, S the sickle at the front edge of the platform, and B the reel-bat secured to the oscillatory arms 0. Said reel-bat arms are supported from the front ends of the vibratory bars A, whose rear ends are attached to the cranks H of the shaft H. To pivotally support the bars A, and at the same time permit their reciprocating movement, I provide the sleeves G,which are adapted to slide along the guide-rods F, and are pivoted to the collars G on the bars A. By changing the positions of the collars G toward one end or the other of each bar A the leverage of said bars is changed and the vertical play of the reelbat B increased or diminished in proportion to the distance of said collars from the ends of the bars A. A set-screw or other fastening, G, secures each collar G at the desired place.

If the reel-bat B is fastened directly to the ends of the bars A, the horizontal movement thereof is only equal to the length of the stroke of the cranks H. To secure a sufficient movement of the reel-bat thus operated, the said cranks must be quite long and the bars must move as far and fast as the reel-bat. This Serial No. 155,370. (No model.)

construction is therefore open to the objection that the required motion of said bars may shake and jar the reaper. The path of the reel-bat will also be oval. To render such path approximately rectilinear, or so at least when the reel-bat is approaching the sickle andplatform and rising therefrom, and also to decrease greatly the stroke of the bars with the same horizontal play of the reel-bat, I have devised the following construction: The reelbat B, instead of being secured to the ends of the bars A, is fastened to the ends of the oscillating arms 0. These arms are pivoted to the ends of said bars, and thus means are provided to oscillate them forward when said bars advance, and to swing them backward when the bars retreat. This will then considerably increase the horizontal movement of the reelbat and somewhat modify its vertical play. For thus oscillating the arms 0 relative to the bars A, the means which I have adopted consists of a simple connecting-rod, D, joining the prolonged upper end of each arm 0 to the guide-rod F. Now, as the bars A move in a horizontal direction, the upper ends of the arms 0 being held by said connecting-rods, the lower ends of said arms, and therefore the reel-bat, are moved a greater distance. By changing the pivotal points of these arms and connecting-rods variations in the path and the throw of the reel-bat can be made.

As shown in Fig. 2, my oscillating arm-connection of the reel-bat to the vibratory reciprocating bars gives the desired rectilinear path to the stroke of the reel-bat.

The desirability of the rectilinear path of the reel-bat lies in the fact that it enables the said reel-bat to pass straight down in front of the grain without beating any down, and to sweep the grain to the sickle and onto the platform, and to rise up therefrom without carrying any of the grain up with it.

To revolve the shaft H, and thereby give the required motion to the reel-bat mechanism, I usually mount a bevel-gear, K, on said shaft, and have said gear mesh with one on some shaft of the reaper orharvester. In some machines a sprocket-wheel and chain might be more advantageous. The bearing-brackets J of said shaft I make vertically adjustable by I j ustment.

having the stems J intwo parts, held together i ends of said oscillatory arms to fixed points,

by bolts passing through slots therein. The position of the center of motion of the reel-bat B is varied by this adjustment of the bearings J. I prefer'to have the stems J curved, as shown in Fig. 2.

To adapt the reel-bat for either high or low grain by so adjusting it as to make its workingpath high up from the ground or low down, almost,if not quite,touching the ground,Ihave devised the following means: The rear ends of the guide-rods F are pivoted or hinged to the rear edge of the platform P, and their front ends are provided with means for vertical ad- To secure both rods F rigidly together,,so as to enable the adjustment of one to similarly affect the other, I fasten the rear portion of each to the tail-board P, as shown in Fig. 1. From the front end of one guide-rod F extends the connectingrod M to the crankarm N of the rock shaft N. By oscillating said crank-arm toward or from the guide-rods the end of the latter is raised or lowered ac- L cordingly. For operating the crank-arm N rock-shaft N.

' L engaging with the teeth of the said rack and operated by the hand-piece L. Said'lever L is prolonged downward, and is provided with a stirrup at its lower end, to enable the same to be controlled by the foot of the driver.

WhatIclaim as my invention, and for which I desire Letters Patent, is as follows, to wit:

1. In a harvester, the combination of the reel-bat, the arms to which said bat is secured, and the vibratory bars supporting and operating said reel-bat arms, whereby the grain is delivered to the sickle and upon the platform, substantially as described.

2. In a harvester, the combination of the reel-bat, its supporting-arms, vibrating bars supporting said arms, sliding pivots supporting said bars, and cranks for operating said bars, substantially as and for the purpose set forth.

4. The combination of the reel-bat, the oscillating arms to which it is secured, and the substantially as and for the purpose specified.

6. The combination, with the reel-bat and vibratory bars supporting the same, of the shaft and cranks operating said bars, the guide-rods, and sleeves pivoted to said bars and adapted to slide along said guide-rods, substantially as and for the purpose specified.
