JOHN F. STEXVARD, OF CHICAGO, ILLINOIS.

HARVESTER.

SPECIFICATION forming part of Letters Patent No, 360,120, dated March 29, 1887.

Application filed September 1, 1886. Serial No. 212,427.

To ctZZ whom it may concern.-

Be it known that I, Join: F. STEWARD, 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 I-Iarveste1's,wl1ich are fully set forth in the following specification, reference being had to the accompanying drawings, forming a part thereof.

Figure 1 is a perspective of a portion of a harvester-frame and the drivewheel axle and the raising and lowering pinions thereon, containing my invention, the direction of view being from the rear outer corner. Fig. 2 is a horizontal section through the drivewheel axle and segments.

A is thefront sill; B, the rear sill; G, D, and It, respectively, the outer, middle, and inner trusses which connect the front and rear sills.

F and G are respectively the outer and inner segments.

K is the drive'wheel axle; L, the raising and lowering pinions thereon.

c d e are the lower bars of the trusses O, D,

and E, respectively. 0, d, and e are the upper bars of the said trusses, respectively.

The segments F and G are secured, respectively, to the trusses O and 1), serving as struts for the same. The lower bars, d and e, of the trusses D and E are tied together at thelower end of the inner segment, (l, by the crossbar H, and from the upper end of the segment G to the inner end of the bar H is extended the brace I, which is made fast at the upper end to the segment and at the lower end to the bar H and to the lower bar, 0, of the truss E. This latter connection is almost directly in a vertical line with the crest of the upper bent bar, 6, of the truss E, and near this point the upper and lower bars, 6' and e, are rigidly connected by the rod J, which is inserted through both bars and provided with jam-nuts on both sides of each bar, thusforming a strut for the truss E.

The purpose of this structure is to prevent the sagging of the segment G in either direction. The triangle formed by the segment G, the horizontal bar H, and the diagonal brace I, resting its inner angle upon the bar e, and said bar being tied to the bent upper bar, 0,

- of the truss E, the benefit of the vertical rigidity of the truss is obtained, to prevent the drooping or sagging of the said grainward (No model.)

angle of the triangle G H I; hence, to prevent the segment G from leaning grainward, and the bar II being made fast to the bar 6, the segment G is by the same means prevented also from leaning stubbleward-th at is, toward the wheel.

The segments G and F are held at uniform and nnvaryingdistance apart by means of the axle K and the pinions L L, made fast thereon. Said pinions, meshing in the racks F and G on the segments F and G, are shrouded at both edges, so that they engage the racks laterally, whereby the racks, and hence the entire segments, are prevented from lateral displacement relative to the pi nions. By this means the benefit of the described bracing pro vided for the segment G is extended to the segment 1?.

In thejoint application of Herman N. Kennedy, Burr A. Kennedy, and myself, filed Oe tober 19, 1886, Serial No. 180,261, there is -shown the inner segment braced by rods extending from its upper end tothe front and rear sills, and the pinions on the drivewheel axle doubly shrouded and engaging racks of the segment respectively; but said construction is not therein claimed, it being my sole invention.

I claim- 1. In combination with the front and rear sills and the trusses D and E, connecting them on the grain side of the wheel, the segment G, secured to the truss I), the rod J, strutting the truss E, the cross-bar H, and the brace I, united and operating substantially as and for the purpose set forth.

2. In combination with the front. and rear sills and the truss D, connecting them on the grain side of the wheel, the inner segment scoured to said truss, and a brace connecting the upper part of said segment with a fixed part of the harvester-frame grain ward thereof, and the drive-wheel axle and the raising and lowering pinions made fast thereon and engaging the segment-racks and shrouded on both sides thereof, substantially as set forth.

In testimony whereof I have hereunto set my hand, this 21stday of August, A. D. 1886, in the presence of two witnesses.

JOHN F. STEWARD.
