SPECIFICATION forming part of Letters Patent No. 492,412, dated February 28, 1893. Application filed May 31, 1892. Serial No. 435,047. (o model.)

To all whom it may concern:

Be it known that I, MELVIN S. MISHLER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Harvesters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the let-.

ters of reference marked thereon. which for] a part of this specification.

My invention relates to grain harvesters and binders and has forits object sucha construction of the frame of the machine as to provide a low horizontal binding table and means for adjusting its elevation, and also the further object of providing such an arrangement of the guide-wheel as will facilitate the turning of the machine.

In the accompanying drawings, Figure 1 is a perspective of the frame of my improved machine. Fig. 2 is a plan view of the forward portion of the frame.

I have shown in the drawings only such parts of the machine as relate to myinvention.

The frame is forlned of the middle, rear, and front sections, A, B, O. Section A is intended to support the binder table or platform,-the grain table being rigidly attached to it and supported bythe sills F, F. The binder table is at a greater elevation than the grain table, as indicated, for the purpose of affording space beneath it for the play of the binder needle.

The main or drive wheel, not shown, is mounted upon the axle G, which is journaled in the side bars of section B. The frame A, is provided at its rearward end with backward projectinghinge brackets a, a, by means of which it is pivotally attached to the frame B, as shown at b, so as to allow of Vertical fiexure.

The third section, C, of the frame of the machine is hinged to section A, by means of pivots passing through the brackets a', a', as shown at o, so as to allow of Vertical flexure.

The side bars of section O, may be parallel or they may converge forward as shown, and are united at their forward ends by a single cross-piece, and at their rearward ends by a downwardly projecting bracket which carries a roller i, hereinafter referred to.

The forward ends of the side bars of section B, project downwardly, their ends being united by a rigid cross-bar b'. A cable, or, as shown, the combination of a rod I-I, and a lehain h, extends from the lower ends of the side bars of section B, as shown at h', h, un- Ider the roller to a windlass I, mounted ;transversely on section O. This windlass is provided with an ordinary orank '2, and a y ,lstop device consisting of a simple ratchet 1and pawl 2'3. A lever arm L, is rigidly at- ;tached to one of the side bars of section A, `and projects backward alongside of section B, and is provided with a spring pawl Z, of ordinary form, for engaging a segmental rack M, projecting upwardly from the adjacent side bar of section B.

4The binder table is elevated by the winding of the chain h, upon the windlass, thus shortening the distance between the latter and the points 77/, h'. This operation tends to tilt the outer sections by raising their adjacent ends, and the binder table is carried up with them. For the purpose of better controlling the action it is advisable to allow sections A and B to remain locked together by the pawl Z, until the chain has been sufficiently shortened. The pawl being now released the joint uniting Sections A and B is easily fiexed by means of the lever L, the binder table being brought to a horizontal position and the rearward section tilted to a greater degree.

In the use of a harvester frame oonstructed as above described, it is necessary that the forward end of the machine be supported by a wheel.

Difficulty arises from the use of such a wheel in turning the machine, it being necessary in order to avoid loss of time to make a right angle turn, the machine turning upon the main or driving wheel as an axis. To accomplish this purpose and for the additional object of bringing the forward end of the machine as near the ground as possible While permitting the use of a large guide-wheel, I make use of a truck D, for this wheel which is hinged, so as to swing vertically, to the forward end of the side bars of section O, as

ICO

D, and its upper end is provided with a short` Crank arm 7c', which is united to the tongue i E, of the harvester, by means of the link e. The tongue E, is pivoted to thetruck D, at e', so as to swing horizontally. The link e, is pivotally secured tothe tongue E, at a distance from the pivotal point of the latter, greater than the length of the Crank arm 76', so that a slight angular movement of the tongue E, Communicates a greater angular movement to the guide-wheel K,as indicated by the'dotted lines in Fig.2.-

I have not shown the means of elevating the -outer end'of the graintable as any of the methodsl in use for this purpose may be adopted.

It is obvious that the locationof the downwardly projecting'bracket carrying-the roller z, may be zupon the frame A,.instead of upon` the frame O, as shown, or that'tvarious changes of this Character might be made without' departing from the soope of the invention. The essence of the invention'is that the forward andrearward'sections are united by a Cable or Chain passin g 'below the central section, some r portion ofthe Cable being depressed, when the binder-'tableis at its lowest elevation, below the supporting points of-the Sections to which it is attached so'that .the shorteningof the cable will tilt the two outer sections,rcarrying up the Central section.,

I am aware that harvesters and binders have been made with jointed frames-'andtwith a for-Ward or guid e-wheel adapted to be turned sharply by a slight angular movement of the tongue ofzthe machine, and I do not broadly.

Claim these features.

WhatI Claim as my invention,.and desire frame anda forward 01' `guide-wheel frame0,.
