SPECIFICATION `forming' part of Letters Patent No. 712,409, dated October 28,1902. Application iiled December 28,1900. Serial No. 41,356. (No model.)

To LZZ whom t 17m/y concern.

Be it known that we, JOHN W.PR1DMonn and WILLIAM WEBBER, citizens of the United; States, residing at Chicago, in the county of Cook and State of Illinois, have invented cer.

tain new and useful Improvements in Harvesters, of which the following is a specifica-j against the various strains to which they are exposed in fieldwork.` Its objects are to sirn-I plify the construction of thevmachinenwhile in; creasing its stability; tomore efficiently secure and sustain its component members in opera-f tive relationship and counteract the disturb. ing forces to which they are subject; to so com-l bine the several mechanisms as to obtain the greatest possible strength with the least weight without obstructing the spaces which for the purposes of themachine should `be kept open, and to dispense withparts heretofore employed, while retaining or increasing the advantages which they were intended to contribute.

In the accom an 1in r drawings Figure I is b D b a front elevation Vof a harvester embodying our invention, omitting certain portions of the machine not material for its illustration. Fig. 2 is a side elevation of the same; Fig. 3, a plan; Fig. 4, a rear elevation; Fig. 5, a detail View from a cross-section on line m, Fig. 3, looking in the direction indicated vby the arrow; and Fig. (i, a detail View of a portion of the support of the binder and parts connected thereto as seen from the opposite side to that shown in Fig. l.

A represents the main wheel of the har-- vester; B, the finger-bar; C, the elevator; D, the binder; E, the bundle-carrier. Parts not required furthe illustration of this invention are omitted.

l and 2 are the longitudinalsillson each side of the main wheel.

3 is a bent angle-iron secured at one end to the linger-bar and thence extendingr across the front ends of the longitudinal sills l and 2 and firmly united thereto, thence extending to the front end of the crank-shaft, there bent to form an elbow, in which is supported the box for the crank-shaft, thence extendy rthe driving `mechanism, the binding mechanism,"the'elevator mechanism,` and (when desired) the bundle-carrier. i On it are mounted the uprights 5 and 6,`carrying the front of the elevator. J ust above its elbow is secured the bracket 7, in which is pivotally mounted the arm 8 of the bundle-carrier, which is further supported from the upper end of this bent cross-sill by the pivoted rod 9, thus constituting a truss-support for the bundle-carrier. The rod IO, extending from the elevator-frame to the upper frontend of the binderframe, cooperates with this bent cross-sill in firmly supporting the binder in iixed relation to the driving mechanism.

l1 is a U-shaped tube extending rearward j under the elevator from this bent cross-sill near its junction with the nger-bar, connected to the foot of the elevator-frame both front and rear and to the rear cross-sill 12, behind which it bends upward, then forward, connecting with and supporting the upper elevator-frame at both front and rear and having its front ends united by the upright 13, on which rocks the lever 14, by which the machine is tilted. To the front lower end of this U-shaped tube is pivotally attached a Vdraft rod and brace 15, which connects with the tongue 16, thereby exerting the draft, es-

pecially when the machine isturning, di-v IOC secure it to the longitudinal sill and to provide a stable bearing for the crank-shaft in proper relation to both. This crank-shaft has its bearing at the rear end in a bracket 18, which fits into the angle of the rear crosssill and is extended to embrace longitudinal sill 2 and aord a bearing thereon for the, driving-shaft 19, being also secured to sill 2 I and rear cross-sill l2 at their point of intersection, and to sill 2 in .front of shaft l9it affords, in connection with the front bracket and its supports, a simple but effective means of maintaining the crank-shaft and drivingshaft free from cramping strains and of unitl The lateral or ing and bracing the two sills. cross sills are formed ot' angle-iron, with their inner faces fitting over the ends of the hollow longitudinal sills l and 2, thus serving to "close the ends of these hollow sills while afand the platform,and braces these parts upon each other.

2l is a rod extending from the top of the elevator-frame to the binder-supporting post 22.

-25 is the 'sliding tube of the binder, which is supported in a bracket on the upper end of sill 3 and slides on the antifriction-Wheel 24, mounted in said bracket, as, shown in Fig. 6. vBy this construction, of which the U- shaped element uniting and supporting the mechanisms longitudinally and vertically and the front bent cross-sill uniting and supporting them `,laterally and vertically are the dominating features,we secure great strength and rigidity in the composite machine and dispense with many ,parts before required, while securing better results.

We claim- 1. In combination with the U-shaped longitudinal and vertical support, the draft and brace rod attached to the front of the lower arm and extending thence to the pole, for the purpose described.

2. In combination with the U-shaped longitudinal and vertical support, the upright uniting its front ends, and the tilting lever mounted thereon, substantially as'described.

3. The combination Vof the vfron-t cross-'silt bent upward and forming a support 'for the binding mechanism, the'bracket mounted on the upward bend thereof adapted -to pivotally support a bundle-carrier, a bundle-carrier, and a rod pivotally connected vto said upward bend above said bracket and to the bundle-carrier, substantially as described.

4C. In combination with the cutting, vbinding and bundle-carrying mechanism-cfa har- Vester, the front cross-sill connecting `the same, and a bracket mounted on an upward extension of said sill having a sliding bearing for the binder and a pivoted connection for a rod extending therefrom to and supporting the bundle-carrier, substantially as described.
