IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 61,953, dated February 12, 1867; Reissue No. 3,627, dated August 31, 1869.

To all whom it may concern:

Be it known that I, AMOS RANK, of Salem, in the county of Columbiana and State of Ohio, have invented new and useful Improvements inReaping an d Mowin g Machines, of which the following is a full, clear, and exactdescription.

The invention herein claimed relates to that class of combined reaping and mowing machilies in which the inner or heel end of thefinger-beam is secured to the rear end of a dra-gbar arranged longitudinally relatively to the path of the machine, and pivoted at its forward end to an eyebolt turningin a socket connected with the main frame, by which means the dragbar isfree to turn axially in its socket, and also to rise and fall bodily, without aifecting the movements of the frame,thus enabling the cutting apparatus freely to coliform tothe surface over which it slides.

In the class ot' machines above mentioned, when adjusted for mowing, the crank-pin, the pitman, and the eye of the cutter-bar usually lie in substantially the same vertical plane. When, however, the cutting apparatusis raised for reaping the drag-bar causes the heel end of the finger-beam to rise inthe arc of a circle of Which the eyebolt of the drag-bar forms the center, and, as the crank-pin remains in its former position, the eye of the cutter-bar is necessarily carried backward out of the plane of the crank-pin, in consequence of which change of position the cutters and pitman are apt to become bound and to work hard.

Now, the object of the invention herein claimed is to overcome the difficulty thus caused, which difficulty has been found in practice to be a serious one, to which end my improvement consists in the application to the swivelcounecting-pin at theforward end of the drag-barof a collar or gageof such determined `length that when placed in rear of the socket on the eyebolt the cutting apparatus will be adj usted and held to its proper position relatively to the cran k-pin and pitman formowin g, and when placed in front of the socket the parts will be adjusted to the proper position for reaping, whereby I am enabled to secure the requisite adjustments with unerring certainty and without measurement simply by changing the position of the collar. i

In the accompanying` drawings, which make part of this specification, Figure 1. represents a plan or top view of so much of aharvesting-machine embracing my improvement as is necessary to illustrate the inventionherein claimed,

showing the relative position of the parts when bolt or connecting-pin, to which the front end of the drag-bar is pivoted.

In the accompanying drawings a mainframe, A, is shown as supported on an axle on which wheels B are mounted. The linger-beam L is suitably connected with a drag-bar, C, the front end of which is is pivoted to an eyebolt, a, which turns freely in a bearin g or socket, g, projecting from the main frame. In this instance the finger-beam is shown as hinged to the dragbar. This bolt a. should be made of a length so much greater than that of the bearing gy as to receive a collar, 7L, and also a nut to retain the bolt in its socket. Then mowing the collar h is arranged on the eyebolt betweenv its eye and the socket g, as shown in Fig. 2 and in red lines in Fig. 3. When the parts are in this position the crank-pin, cutter, and thepitman are all in the same vertical plane and will work smoothly. fhen the cutting apparatus is raised to adapt it to reaping the collar his removed from behind the socket and placed in front of it, the drag-bar, cutting apparatus, and eyebolt being moved forward a distance equal to the length of the collar, as shown in black lines in Figs. l and 3. By inspecting Fig.3 it will be seen that in either position thecrankpin, the cutter, and the pitman always remain in the same vertical plane, whether adj usted up or down, and consequently there will be no binding of the joints or other parts.

I am aware that drag-bars heretofore have been adjusted by means of a nut and screw; but I am not aware that a gage-collar has been so used in connection with such adjusting device as to determine the proper adjustmenty of the cutting' apparatus for either reaping or mowing by its arrangement on the eye, adjusting-pin, or swivel-connection relatively to its socket, as in my device, by means of which the most inexperienced hand is enabled readily to change the machine from a reaper to a mower.

What I cla-inl as. my invention, and desire to secure by Letters Patent, is-

1. The combination, in a harvester, of a bearing projecting from the main frame, a swiveling eyebolt working in the bearing, and a gagecollar fitting on the eyebolt and changeable I from one side of the socket to the other, the combination bein g and operating substantially as setforth.

2. The combination,in a harvester, of a fixed bearing or socket, a changeable gage-collar, a longitudinallyadj ustable eyebolt and a Vibrating drag-bar with a hinged cutting apparatus, the combination being and operating' substantially as set forth.

In testimony whereof I have hereunto subscribed my name.

AMOS RANK.
