IMPROVEMENT IN HARVESTERS.

Spcification forming part of Letters Patent No." 77,524, dated May 5, 1868.

. To all whom tt may concern:

beinghad to the accompanyng drawings, mak= ing a part of this specification', in which- Figure 1 is an elevation of one side of the improved machine. Fig. 2 is a longitudinal section through the machine, taken in the vertical plane indicated by line 90 00 in Fig. 3. Fig. 3 is a top view of the machine, with portion broken away. Fig. 4 is a bottom view of the driving-wheel for vibratin g the lever which moves the sickle, showing the cam-head on said lever. Figs. 5 and 6 are views of myimproved finger-guard.

Similar letters of reference indicate correspondin g parts in the several figures.

This invention relates to certain novel im-.

provements on that class of reaping and mowing machines in which the animals which move the machine are placed behind the cutting ap paratus and the main frame.

The nature of my invention consists, first, in the manner herein shown of combining an endless wire, braco, or stay with two light disks or circular pieces of wood or metal, which have pins set in their periphery, for the purpose of making a strong light pin-wheel for operating the pitman-driver of a harvester, this construction being cheaper than the solid serpentine cam-wheel or solid pin-wheel, and answering all the purposes of the same, with less fricton, it also being stronger and firmer than a wheel formed of two disks with camsurfaces opposite one another, and serving to give a more regular motion; second, my invention consists, further, in constructing the guards in the manner herein shown and de scribed, so that that part of the slot in which the sickle moves shall only be about the same size as the thickness of the sickle, while that part of the slot which is forward of the front ends of the sickle-sections shall be greatly enlarged in the form of a circle or ellipse. Thus, while I secure a perfect surface for the edges of the sickle to cut upon, I also prevent elogging by providing a free clearing-space in front of the ends of the sickle-sections.

To enable others skilled in the art to understand my invention, I will describe its con struction and operation.

n the accompanying drawings, A A represent the driving-wheels, which are both applied loosely upon the axle B; and a repre sents a forked clutch, which passes through the hub of the wheel A, so as to engage with lugs which are formed on a collar, a, that is keyed fast upon said axle. This clutch is used for engaging wheel A with its axle B when it is desired to operate the sickle, and todisengage said wheel when it is not desired to operate the sickle. l

C C represent two longitudinal beams, which project out in front and rear of the axle B, and are suspended beneath the same by means of the bearings b b, as shown. Beneath these beams G O, and secured to them by means of short posts, are two longitudinal beams, C C, which extend forward of the axlel3 and beams 0 a sufficie'nt distance to Support the grainplatform D in front of the driving-wheels A A, and in front of the guardboard or fender D, which extends transversely across the lower beams in front of the drive-wheels.

The beams C O are connected together at their rear ends by means of a transver se bar, o, and at their front ends by means of a transverse bar, d. The ends of the two bars c and d project out laterally, and have the reel-supporting arms 'E E secured to them, as shown in Figs. 1, 2, and 3.

The front ends of the beams C C have the finger-beam e secured firmly to them, which beam has secured to it the guard-fingers g g, upon which the sickle g reciprocates. One end of this sickle g has a bent arm secured to it, to which arm a pitman-rod is attached, which plays in a groove in the finger-beam e, and is attached at its inner end to the forward end of a vibrating lover, Gr. This lever proceeds back, and has a cam-head, 'h, applied to its rear end, which is acted upon by means of studs i upon the peripheries of two wheels, J J, on the main axle B. The studs on wheels J are arranged at such distances apart and in such manner as to act alternately upon the taperiug sides of cam 7L as the wheels, with their axle, are revolved, and to give a rapid vibrating motion to the lever Gr. The two wheels J J are keyed upon the axle B at suitable distances apart, and secured against lat eral strain by means of the diagonal rods 9-, which pass around the studs and also strengthen these studs.

The tongue K has hounds l l secured to its forward end, which hounds are pivoted to the rear posts 3 3, which connect the upper and lower beams ofthe main frame together at points 2 below the axle B. The tongue K proceeds back beneath the bar c-a-suitable=dis tance, and is supported upon aflanged guidewheel, L, the standard L of which passes freely through the tongue, and =has a handle N is in aposition where itean loe grasped by the person sitting upon seat M, whocah, by

rai-sing and lowering it,adjust the cutting apparat'us *higher or lower, as heymay require.

In Fi gs. 5 and 6 I have represented enla1ged stead of -guard-finger heretofore used. It is ma;dof rod+of metal, bent in the form shown in Fig. 5, so as to leave an eye, p, which forms the front termination of the space in which the sickle works. This eye is tapered, as shown in Fig. 6, so as to afl'ord as little ob structionas :Possible to its passage through the grass or grain. This eye p will allow the free escape of anything which may get into the space between the sickle and its guard.

Having described my invention, what I claim as new, and desire to secure by Letters Paitent,is-=

1, The pin-wheel J J, constructed of two light disks, with pins Min their periphery,

and with an endless bracing or staying*wire, j, passed diagonally 'fromone diskto theother around the pins z, in combination with the devioe*h, whichdrives the sickleof a harvestersuch as described, -all substantially as described.

2. Theguard-fingersg, Constructed,asshown in I igs. 5and6, Witha -narrowstraight slot,

terminating in -anelliptical 'or'circular'eye, for the purpose set forth.
