'UNITED STATES ROBERT BROWN, OF NEWARK, OHIO.

IMPROVEM ENT IN HARVESTERS.

Specification forming part of Letters Patent- No.32,556, dated June 18, 1861; Reissue No. 1,769, dated September 20, 1864.

To all whom it' may concern:

Be it known that I, ROBERT BROWN, formerly 0f the city and county 0f Frederick, in the State of Maryland, but now residing at Newark, in the county of Licking and State of Ohio, have invented certain new and useful Improvements in Harvesting-Machines; and Ido hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which- Figure 1 represents a rear view of the said harvesting-machine, showing the rake-frame partially in section to show its attachment to the finger-beam. F|g. 2 represents a top view of the machine as adapted to mowing. Fig. 3 represents a section through the line 1 1, Fig. 2, showing the rake-frame and rake-shaft. Fig. 4 represents a perspective view, exhibiting the mannerof attaching an additional number of rakearms.

.The nature of my invention consists in rigidly connecting 'the rake-frame of a harvesting-machine with the hinged linger-beam so that the rake can rise and descend with said finger-beam and platform when the machine passes over uneven ground; also, in an improved manner ot' mounting the rake; also, in an improved combination ofdevicesfor attaching the reel or rake to adapt it for any desired number of arms.

A A are the driving-wheels, carrying cogged rings B, which gear with pinions U,jonrnaled loosely upon the shaft D, so as to impart motion thereto only when the machine is moving forward and when placed in gear. Reciprocating motion is thence communicated' to the cutter E through the medium of bevel-gears F G, shaft H, crank-wheel I, and connect-ingrod J in the customary manner.

L represents a hollow or divided shaft whose journalsl land a are respectively supported by the journal-boxes M M and Z, Figs. 2 and 3, and which freely swing on itsjournals. It

has a crank-shaped part, O, to which the finger-beam K ofthe machine is bolted,and which ringer-beam can thus freely turn, with the shaft L as its fulcru'm, to rise and descend When the machine passes over uneven ground. The hollow shaft L -has also suitable innerbearings, which serve as journal-boxes for the shaft H of the crank-wheel I. .The said hollow shaft L is also provided with suitable flanges, b b c, for. the reception and support of the rake- 'rame V of the machine, as shown in Figs. 1, 2, and 3.

The vertical shaft U of the rake is journaled at d to the rake-frame V, projecting upward therefrom.

The arms N of the rake or reel rest upon a ring, T, and are rotated through the medium of the pinion R, spur-wheel S, pinion P, crownwheel Q, and shaft U in the customary manner.

The ring T, which supports the rake-arms in their movements, is supported bythe rodsff gi, to which it is pivoted at e e d d. The rodsf pass through suitable flanges, Z, in the rakeframe, and their height can be adjusted by means of the adjusting screw-nuts y. The lower end of the rodsI gis supported on the brace m, whose upper end is secured to the rake-frame, and whose lower end is bolted to the finger-beam. The length ofthe rod g can also be adjusted by means of screw-nuts u, and thus the inclination of the ring T can be adjusted with the greatest accuracy, so as to canse rake-armsto perform their proper motion over the platform.

From the above it will be seen that the frame which supports the rake has a rigid connection with the hinged linger-beam of the machine, and consequently the rake itself will participate in all movements of said linger-beam when the machine passes over uneven ground, that the relative positions of the rake-shaft and rake-arms to the linger-beam and platform are not changed by the swinging motion of the latter, and that thus the perfect operation ot the rake will not be interrupted or deranged in any manner when the machine passes over uneven ground.

When a four-armed reel is employed one arm is provided with a rake-head, as shown in Fig. 1. In this arrangement each pair of arms is mounted upon a metal ring, o, encircling the shaft U, and is secured thereto by a holt, as represented in Fig. 1. When six arms are required the ring o of the center pair is constructed with bolt-holes 2, set obliquely to the arms, and a bridge, m, perforated for the attachlnentl of an arched yoke, p, to which the upper pair of arms is secured, as shown in Fie'. 4. By this meansa reel of either two, four, or six arms may be used, the arms in either case being eqnidistant and adapted to revolve in one plane. In a six-armed reel two are usually provided with rake-heads.

rlhe construction of the iingerbeam is exhibited in Fig. 3.

gis a rabbet in front on the under side of the bar to a'ordsecure attachment and support for the lingers 1.

s is a rabbet at the rear and on the upper side of the bar to receive the platform ot' the machine without causing it to project above the top ofthe bar, and (when the platform is removed) to allow the grass tofall with greater l freedom.

Wis the gatherer. (Represented in red lines in Fig. 2,) lt consist-s of a bar pivoted at w to the frame of the machine, and is adjustable at any desired angle to deiiect the grain toward the cutters.

X represen ts a lever fulcrum'ed at m to the frame of the machine, and connected with the finger-beam by a link, Z. i

The other parts of themaclne not being embraced in my invention their description is dispensedwith.

Having thus fully described the nature of my invention, what I claim herein as new, and desire to secure by Letters Patent, is- Y l. Rigidly connecting the rake-frame, which is supported on VVthe main frame of the machine, with the hinged finger-beam in such a manner that the rakeshaft does not change its relative position to said linger-beam when the latter is raised or lowered in passing over uneven ground, substantially in the manner and for the purposes herein set forth.

2. Securing both the finger-bar and rake- I frame to a hollow shaft, L, the journals l ot'.

ROBERT BROWN.
