SPECIFICATION forming part of Letters Patent No. 351,268, dated October 19, 1886.

Application tiled October 19, 1885. Serial No. 130,261. (No model.)

To all whom it may concern:

Beit known that we, HERMABN N. KENNEDY, BURR A. KENNEDY, and JOHN F. STEWARD, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Grain-Harvesters, which are fully described in the following specification.

This invention relates to the general construction of a grain-harvester.

It comprises novelgform of the longitudinal and transverse bars of the fra-ine, novel mode of securing the same together and to the upright portions of the frame, novel form of the junction-pieces, whereby they afford bearings for the gearing, and novel location of the gearing. y

In the drawings, Figure 1 is a plan. Fig. 2 is an outer side elevation. Fig. 3 is a front elevation, the pole being shown in vertical section. Fig. 4 is a rear elevation. Fig. 5 is an outer side elevation of the outer truss and segment and the gearing having its bearings on and ai'ljacent thereto. Fig. 6 is an inside elevation of the inner truss and segment and raising and lowering screw thereon. Figs. 7, 8, 9, and are perspectives, respectively, of the outer rear, outer front, inner rear, and inner frontj unetion-pieces ofthe wheel-inclosing frame. Fig. 11 is a perspective of a bushing or thimble which forms a bearing for the sickle crank-shaft. Figs. 12 and 13 are respectively front and rear elevations of a certain A-frame which'sustains the elevator. Fig. 14 is a rear elevation of the platform. Fig. 15 is a Vertical section through o o on Fig. 14. Fig. 16 is a detail elevation of the inner segment and truss and raising and lowering mechanism.

A is the front sill or frame bar, and A' is the rear sill or frame bar. Both are made of tubular metal, and in practice iron gas or water pipe is used for the purpose. They are secured together by the trusses B and B', the former outside and the latter inside the drivewheel.

C and C' are respectively the outer and the inner segments, which are secured to thev trusses B and B', respectively, in such manner as to constitute the struts'for the same.

The truss B comprises the upper and lower bars, Z) b, and the clips D' and DL, which unite said bars at their ends, and the truss B' comprises the similar bars, b' b', and the clips D3 and D", uniting the ends of said bars. The beams b b and b b' of the trusses B and B' are formed of angleiron, secured together at the ends or angles ofthe trusses by the angle-clips D' l)2 and D D. Said clips are provided with tubular sockets or apertures di" d20 P0 tlm, to receive the sills A A'aud afford the means of securing the trusses to the sills. They have also the several bearings for the gearing and the raising and lowering mechanism, as hereinafter fully explained in detail.

E is t-he drive-wheel. c is its hub. c is the axle. The wheel is loose on the axle, and the latter has pinned fast to it the pinions E' E', meshing;` with the racks c c' ofthe segments C C'. Said axle c' has also pinned fast to it the sprocket-wheel Fr', and the drive-wheel E has formed integral with its hub c the sprocketwheel E.

The rear sill, A', is made to serve as the axle upon which isj o u rnaled the beveled gear-wheel F, whose web F' is made bell-shaped, for a rcason hereinafter explained, and whose hub F2 is elongated into a sleeve, as illustrated, and has integral with it the sprocket-wheel F3, in the same verti cal plane wi th the sp rocketwheel E". The endless chain f passes around the two sprocket-wheels 1 and FS and communicates motion from the former to the latter. The rear sill, A', also serves as the shaft upon which is journaled the sprocket-wheel Gin the same Vertical plane with the sprocket-wheel E2, and having integral with it the wormwheel G'. The clip D has the tubular aperture d, to receive the sill A', and is bolted firmly to said sill by the bolts d', which pass entirely through both the clip and the tubular sill A'. In a plane at right angles to the aperture dim, said clip has the two bearings di d, in which is journaled the crank-shaft II, which is provided between said bearings with the endless screw or worm H'. Said worm meshes into the worm-wheel G', and by the rotation of the crank-shaft H said worm is made to communicate motion to the said worm-wheel G' and rotate thereby the sprocket-wheel G. vThe endless chain g passes around the sprocketwheels G and E2, and the rotation of the former, as described, rotates also the latter and the axle e' and the pini'ons E E', and by the engagementof the latter in the racks c c of the segments C C raises or lowers the entire frame on the axle. The' wheels F3 and G having their axes coincident, and the same being true of the wheels E2 and E2, the connection of the gearing with the driving-power is Vnot disturbed by this adjustment. f

The clip D4, which forms the forward end.

of the truss B, has the tubular aperture d4, through which the front tubular sill, A, ex tends. It is formed on its lower side to fit to it, the same bolts,i fz', also securing the clip D4 to the front sill, A.

This clip D4 has the extension D4o in front of the sill A,to afford an attachment for the pole J, which is pivoted on the hollow stud j and retained by the head of the bolt j', which passes through the hollow studj, as seen in vertical section in Fig. 3.

As hereinafter explained, the `pitman or connecting-rod to the sickle extends inl front ofthe sill A, and the extension D44 of the clip D4 has the opening d4 of sufficient vertical extent to allow for the play of said pitman, which passes through it.

. The clip D' has its tubular socket d4 extended inward to receive the end of the rear sill, A', and is securely bolted thereto by the boltsd. vAt right angles to the socket e140, and in the vertical plane of the beams b b of the truss B, the clip D has the horizontal bearing for the shaft 7c, formed by the bushing or thimble 7c, driven tightly into the clip from the rear. The shaft K extends forward through the center of the truss B, and has a bearing in the front clip, D2. A bevel-pinion, K', on the shaftc, meshes with and is driven by the bevelgear F. Said pinion being small, the shaft K necessarily passes very near to the face or gear-rim of the wheel F. In order, V therefore, to afford room for fastening the rear sill, A', which is the axle of the wheel F, se-

\ ourely to said clip D', said gear-wheel F is given the bell-shaped web F', and into this hemispherical shell the socket (Z444 ofthe clip D' extends, and is bolted to the tubular sill, as above described. The bushing 7c is extended rearward in the tapering end k2, and

'affords a stop for the pinion K,which is loose on the shaft K. Faston the shaft K, at its rear end, is the sprocket-'wheel K2, from which vpower is communicated Vto the various mechanisms on theharvester-frame. The hub of the pinion Khas the clutch-teeth 704, and upon lthe shaft K, betweenthe pinion K and the sprocket-wheel K2, is placed the clutch-wheel K3, revolved by and sliding on the shaft K,

= and provided with the Ispring K4, tending to h old it in engagement with the clutch-teeth of the hub of the pinion K', whereby the shaft K is revolved. Suitable similar means may be employed to disengage the clutch at will.

K, to prevent its longitudinal movement to the y rear.

The clips D', D2, and D4 are provided, respectively,`with the wings (143, d, and d, to afford attachmentsfor uprights to sustain the frame-Work of the elevator and other elevated mechanism. These uprights M, M2, and M4 are all preferably made of angle-iron. M' is secured to the clip D'. M2 is secured to the clip D2, and M4 is secured to the clip D4. The

uprights M' and M2 are connected above the drive-wheel by the horizontal bar M5, also4 preferably of angle-iron. `Said horizontal bar is firmly bolted to the upright M2 and to the bracket N2, (hereinafter deseribed,) which is itselfbolted to the upright M. Immediately above the point of connection of the bar M5 to the upright M2, the latter is bent horizontally inward over the drive-wheel, and the upright M4 is in like manner bent at m4, the said horizontal portions M24 and M44 being parallel, and serving purposes hereinafter explained.

To the rear sill, A', at a short distance inward from the truss-clip D3, is securely bolted the angle-iron bar M4, which is bent first vertically and then horizont-ally inward, the lat- ICC terhorizontal portion, M44, being at the levell Y 'of and parallel with the horizontal portion M44 of the upright M4. To the upright portion M30 of thebar M3, and to the upper part of the upright M', are secured the rear elevator slide bearing-bars O O, the latter fastening being conveniently made by bolting the sheathings O4 to upright and riveting the bars tothe sheathing. The latter junction may be effected by means of the sheathing riveted both tothe slide-bearing bars and `to the said upright; or the latter may be slightly broadened to overlap the ends of the slide bearing-bars and bolted thereto, as shown in dotted lines in Fig. 4, and to the horizontal portion ,M24 of the upright M2, and to the` upright M4"one on each side of the angle m4.-are bolted the front slide bearing-bars, O' O. In these slide bearing-bars are journaled the elevator-rollers O2 O2 O2 O2 in the customary manner, 'near the ends of the slide bearing-bars, so that. the elevator-canvas and the ribs thereon will pass around the ends of the bars in passing over the rollers.

To the outer surface of the slide bearing-bars IIO bars M"M2 M3 M4therefore serve to clamp said 4 sheathing onto the slide bearing-bars. The

sheathing may be further secured by screws, rivets, or nails. IVhile this sheathing adds slightly to the rigidity of the elevator-frame, said frame is complete as to strength without 5 it, the sheathing being only needed as an inie ting the use of thin material for inclosingwalls, saves the space usually occupied by thick walls, being about one inch and a half, and diminishes by that much the length of all partsframe-bars, shafts, and chains-which extend from front to rear without diminishing the interior measurement and carrying capacity ofthe elevator.

It will be seen that the elevator-frame consists, substantially, oftwo approximately rightangled triangles in parallel vertical planes,

having their bases horizontal and at the same level, and their right angles and their vertical angles respectively connected rigidly by horizontal cross-bars, the rear triangle com- 2- `risinU the rear sill A' as its base the u D p z:- i i 2 p right M' as its vertical side, and the rear elevator slide bearing-bars O O as its hypotenuse, the front triangle comprising the front sill, A, as its base, the upright M'Z as its vertical limb,

5o and the front elevator-slide bearing-bars, O' O',

as its hypotenuse. The hypoteuuse is fastened to the base in the rear triangle by the angleiron M3, which is secured to both, and in the front triangle by the upright M4 and the clip D4, secured together, and one fastened to the hypotenuse and the other to the base. For additional security the slant-bars O O5 are added below the slide bearing-bars O' O' and O O, and secured in the same manner to the 4o uprights,respectively. The cross-connections between the two triangles are the trusses B and B', connecting their bases, and the cross-beam M5, connecting their vertical limbs near or at the apex, and to this may be added the horizontal cross-bar M, which is secured to the upper end of the upright M' and to the front slide-bar, O'. In order to further stiffen this frame, and particularly to prevent any foreand-aft strain which may be applied toit, causo inc' torsion of the front and rear sills A and 5 e 7 A', or causing the clips D', D2, D, and D* to slip around on said sills, there are extended from the upper end of the inner segment, C', the braces P', P2, P", and I, the first extending upward and outward and rearward and secured to the uprights h and the second extending upward and outward and forward and secured to the upright M2, the third extending downward and rearward and inward Co and secured to the rear sill, A', and the fourth extending downward and forward and inward and secured to the finger-bar I. These four braces, together with the portion of the inner segment, to which they are secured as to a cen- 55 ter block, are equivalent in effect to two diagonal and intersecting braces secured rigidly together at their intersection in an oblique plane approximately parallel to that of the hypotenuses of the two-end triangle of the elevatorframe, so that no fore-and-aft strain of that frame can occur without producing direct tensile strain upon one or the other of these diagonal braces and being resisted by the tensile resistance ofthe same.

It will be further evident that the braces P2 and P* tend to brace the sills A' and A, respectively, against horizontal distortion or swagging7 backward and downward; and to further assist in the same preventive office there are provided the braces P5 and P6, secured to the lower end of the inner segment, G', and extending respectively inward, upward, and forward to the finger-bar I and inward, upward, and rearward to the rear sill, A', said braces being secured to said sills, respectively, at the same points, and conveniently by the same bolts which secure the braces P* and P2, respectively, to said sills.

N, N', and N2 are brackets which support i various parts of the binding-table and mechanism. la and n' are braeesfor said brackets N and N', and n2 is a hanger in line with the bracket N2 and designed to support the front end of the binder-frame bar Q, whose rear end bears in the said bracket N 2. These parts do not pertain to my invention and need not be further described.

R is the seat-plank, supported by being bolted upon the horizontal portions MH1 and M'1 of the uprights M3 and M4.

The rear sill, A', extends the entire length of the rear of the platform S. Toits under Vside is fitted the plank S', hollowed on the -upper' edge to let in the round sill A', and to the under edge of the said plank is suitably (secured the matched flooring S2, and both plank S' and flooring S2 are secured to the tubular sill A' by the bolts s passing through all three. The plank thus serves as a hanger to connect the flooring to the sill.

The Vfront sill of the platform is formed by the finger-bar I, made of Z-bar iron. To the under side of the lower horizontal lip, i', of this finger-bar is riveted the metal strip I', and the flooring S", being beveled on the under surface at its front edge, forms a butt-joint with the edge of the lip i', which joint is covered by the strip l', which is riveted also to the tiooring S2.
