IMPROVEMENT IN ADJUSTABLE RE EL-POST FOR HARVESTERS.

Specification forming part of Letters Patent No. 105,654, dated July 26, 1870.

To all whom it may concern} Be it known that I, JOSEPH WATTS DAVIS, of Dublin, of the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Reaping-Machines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a portion of this specification, in which- Figure I is a perspective view of the attachment to a rear-cut reapingmachine con structed according to my invention. Fig. II is a detached view of the reel-post stand. Fig. III is a detached view of the pulley-fastenin g for bottom of reel-post. Fig. IV is a detached "view of the ratchet-wheel shaft. Fig. V is a detached view of the spring-bolt and ratchetwheel. Fig. VI is a detached view of the ratchet-fastening. Fig. VII is a detached view of the travelingbrace.

Similar letters of reference indicate corre sponding parts in all the figures.

' To enable others to understand the nature and construction of my invention, I will proceed to describe it with reference to the drawlngs. p 7 V A, in Fig. I, represents the reel-post stand, the bottom of .which is to rest on the inside reaper-shoe, supporting the reel-post B, by

. means of a shaft passing through said post at a point shown by the dotted lines 5 e, more particularly seen in Fig. III, and upon which the reel-post is turned. 0 represents the pulley-fastening, attached to bottom of reel-post,

and which projects through the curved opening D, having a shoulder bearing on the outer surface of the reel-post stand. Said pulley-' fastening is shown in Fig. III. E represents the pulley-fork,iwhich is attached to and fastened by means of a nut underneath said pulley-fastening. F F represent the reel-chain pulleys, which carry the endless chain 'in its passage aroundthe drive-wheel sheave G and the reel-sheave H. The said pulleys FF are so situated that their chain-surface is equidistant from the pivot orshaft upon which the reelpost turns. J represents the ratchet-wheel and spring-bolt, more particularly shown in Fig. V, which moves around the ratchet-wheel shaft, as shown in Fig. IV. K represents the ratchet-fastening, which is attached immovably to the outer end of said ratchet-wheel shaft, and has openings or cogs in its surface, as shown in Fig. VI, to receive and hold the spring-bolt, L represents the traveling-brace- 'a detached view of the same shown in Fig.

VII-which is to be attached on a pivot to a. tongue-socket, at the point shown by the dottedline a, and the cogs of which are supported under the ratchet-wheel by means of the lip M. N represents the reel-shaft, to which is to be attached the reel-spider.

It will be understood by persons who are conversant in reaping-machi nes that the driver will be seated at a point where he can easily reach with his right hand the crank of the spring-bolt J, and, by a simple movement, raise the bolt from its socket in the ratchetfastening K, and, by turning said crank, can lower or raise the reel-post, as may be required, by any irregularities in the stalks of grain being cut by the machine.

The advantages of this peculiar and novel arrangement are that in adjusting the reelpost the tension of the chain is not altered, and, at the same time, the lower end of said reel-post is firmly held in its place by the shoulder on the pulley-fastening 0 as it passes back and forth through the curved opening D. The traveling-brace L, spring-bolt, and ratchet-wheel J, and ratchet-fastening K also furnish a firm support to the reel-post after it has been adjusted. The same arrangement is applicable to a frontcut reaping-machine by fastening the end of the traveling-brace (shown by the dotted line a) to a pivot on the reelpost, near the lip M, and placing the ratchetfastening, spring-bolt, and wheel on an upright post, permanently fixed at'a point so as to be within a convenient reach from the drivers' seat, and at the same time placing the upper reel-chain pulley F on the opposite side of the reel-post, the drive-wheel sheave being also reversed and situated on the wagon of the machine.

WhatI claim as my invention, and desire to secure by Letters Patent, is 4 The pulley-fork fastening 0, having a shoulder-bearing for the foot of the reel-post and supporting-pulley fork E, in combination with slotted stand A, pulley F F, and pivoted reelpost B, the several parts being constructed and arranged to operate substantially as described.

JOSEPH WATTS DAVIS.
