REAPER MECHANISIVI.

SPECIFICATION forming part of Letters Patent No. 434,048, dated August 12, 1890.

Application filed February 15, 1889. Serial No. 300,074. (No model.)

To all whom. it may concern:

I'e it known that I, VILLIAM LOTTRIDGE, a citizen of the United States of America, and

' a resident of Grinnell, in the county of Powesheik and State of Iowa, have invented an Improved Reaper Mechanism, of which the following is a specification.

My object is to narrow the machine when not in use without shifting a traction-wheel, and to facilitate the movement of the cut grain from one endless carrier to another and at the same time straighten the straws, as required to produce a straight gavel and neat compact bound sheaf, and I accomplish the results contemplated, as hereinafter set forth, pointed out in the claims, and illustrated in the accompanying drawings, in which- Figure l is a top view of a reaper-frame to which my improved operative mechanism is applied as required for practical use. Fig. 2 is a top View with one side removed, and Fig. 3 a transverse sectional view of a rotating fork of peculiar construction and specially adapted to be operated in combination with endless carriers. Fig. 4 is a sectional view showing two rotating forks combined with two endless carriers that extend through different planes as required to advance cut grain from the sickle and elevate it to a binder. Fig. 5 is a side view of the rotating forks combined with the platform-frame as required to advance grain from the end of the platform-carrier and to straighten the straws relative to each other. p

A is the rear sill of the main carriage-frame, said frame being supported upon tractionwheels of uniform size and in parallel position at the opposite sides of the frame. Sill A is preferably made of channel-iron.

A2 are the front and rear bars of the fixed section of the platform-frame, made of angleiron and fixed to the irons A3, that extend from the main frame. A4 is ahinged section or extension of the platform-frame hinged to the angle-iron bars or pieces A2 in such a manner that it can be extended and supported in the same plane occupied by the fixed section or part of the platform, and also turned upward and inward, so that it will be within the width of the main carriage-frame, as required to pass through gateways and to facilitate the moving of the machine from one place to another.

To bring the sickle Within the narrowed width of the machine I detach it from the machine and place it on the narrowed platforln.

Heretofore I have made a transformable reaper in which a traction-wheel was combined with an adjustable section of a platform in such a manner that the Width of the machine could be narrowed; butI now hinge a section of the platform-frame to the machine so that it can be extended beyond the traction-wheel, as required for practical use, and readily turned inward to overlap the 'xed portion of the platform without changing the position of a traction-wheel or its supports.

B are drive-Wheels on the axles of the traction-wheels.

B2 is a driving-shaft in` bearings fixed to the frame and connected with the drivewheels B in such a manner that power will be transmitted and speed increased.

B3 is a rotating shaft in parallel position with the shaft B2 and connected therewith by means of sprocket wheels and chains, so that power will be transmitted thereto and speed increased.

c c are the mating parts of a grooved cam or wheel detachably fixed to the shaft B3 in such a manner that they can be adjusted relative to each other, as required, to jointly engage the end of a lever to compensate for Wear and to prevent undue friction. These sections are cast in molds, and their faces, which are subject to wear, are preferably chilled and hardened.

c is a lever pivoted to the frame and connected with the sickle in a common way at one end and extended into the serpentine cam-groove produced by the mating parts c in such a manner that the rotary motion of the cam will im part a vibrating motion to the sickle, as required to cut grain, as the machine is advanced. Power is thus transmitted from the motion of the parallel tractionwheels t0 the sickle and the speed of the sickle increased. An anti-friction roller is placed on the end of the lever that extends into the cam c c. l I

D are rotating rakes, that may vary in IOO length as desired, mounted in parallel position upon the platform and at right angles thereto, as required to engage and move and straighten cut grain advanced upon an endless carrier D2. The upper rotatingrake projects beyond the lower one and over the sickle, so that its tines Willcome in contact with straw that projects fo-rward over the carrier and the sickle. `These rakes are cylindrical in form and constructed in such a manner that the tines will be thrust out to engage and move the grain and drawn in to prevent any straw from being carried around out of the line of advance in which the grain is lto be mowed.

fare the angular heads or ends of my ro tating cylinder.

f are integral circular flanges.

f are side pieces in the form of segments fixed to the angular heads f, as required to produce a hollow cylinder.

g is a crank-shaft that extends through the axis of the heads f, its crank being eccentric thereto.

1 2 3 4 are tines bent around the crank of the shaft at their inner ends'andput through perforations in the cylinder in such a manner that they will be carried around the shaft when the cylinder is rotated and the shaft is stationary.

71. is a gudgeon on the end of one of the heads f, that enters a bearing fixed to the frame in' such a manner that it can be readil y connected with the driving mechanism by means of gearing, as shown in Figs. 1 and The shaft g extends into a bore in the axis of one of the heads f and through a bore inthe axis of the other and into a fastening device i, that is fixed to the platform-frame in such a manner that the cylinder can be rotated while the shaft remains stationary,I as required to project the tines on one side of the cylinder only at each revolution, as shown in Figs. 2 andB, and as required to take hold and let go of the'cut grain that comes in contact therewith and is advanced thereby.

I'claini as my inventionl. In a grain-harvester having a iixed platform extending forward froml the carriagewheels, a platform-section hinged to the grain end of said fixed platform so to extend lat erally and horizontally in front of the carriage-wheels and in the plane of the fixed platform, so that it can be readily turned upward and inward over the fixed section in front of the carriage-wheels, for the purposes stated.

v2. In a4 harvester, the combination, with the platform and carrier, of a rotating rake at the delivery end of the carrier, andla longer rotating rake above it extendingforward over the sickle, substantially as show-n and described, for the purposes stated.

WILLIAM LOTTRIDGE.
