Specification of Letters Patent.

Application filed September 24, 1909.

' atented June :1913.

Serial No. 519,337.

To all 107mm. it may concern Be. it known that t, Jenn E. Gmson, a citizen of the United States, and resident of Port \Vashington, in the county of ()zaukec and State of \Vifseonsin, have invented certain new and useful In'iprovements in Ilarvesters; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention consists in what is herein particularly set forth with reference to the accompanying drawings and pointed out in claims, its main object being to insure the operation oi the n'iaehinery of an ordinary harvester when ground conditions are such that the main-wheel ot' the harvester cannot perform its function as a driver for said machiiuwry; this object being attained by employing a motor (preferably a gasolene engine) of suitable power in clutchcontrolled gear connection with the aforesaid l'nachinery, the motor being mounted upon a truclcthat has universal-joint eonneetion with the rear of the harvester to eom 'iensate for irregularities of surface over which said harvester and truck are traveled and thus prevent cramp in the gearing by which said motor 'and'the harvester machinery are connected.

Figure l of the drawings represei'its a plan view of a trailer truck .in universal.- joint connection with the main frame ot an ordinary harvester, a motor in the form of a gasolene engine mounted on the true and clutchcontrolled gearing connecting the crank-slnrt'ts of the motor and harvester; Fig. 2, a partly sectional elevation o't' what is shown in Fig. 1, as viewed from the side; big. 3, a partly sectional view ot a detail of the me hanism lllt'licittetil by line FJ--3 in Fig. -t-. and said Fig. 4, a similar view indicated by line t t in Fig. 3.

lieterring by numerals to the drawings 5 indicates the rear sill of the main frame, and o the crankshaft of an ordinary harvester rean y for operator-controt of power transmission from its main traction-wheel, T to said crank-shaft. that. is provided with .a sprwitetwhcel tor engagement with an elevator driveehain. not shown.

ts shown in Fig. l, the power transmissin!) gen immprises a. spreehot-wheel fast. or. the main shaft constituting an axle rigid in tin"; main wheel 7; a link-belt CUltl" ot' a spanner lover (not shown) Convenient to the operator-ct the machine. lllowever any suitable power transmission gear under operator control may be employed. I

Embracing the sill 5 are clips 9 having split-thimble extensions 10 at right-angles thereto. The arms of each clip are bolted together under the sill 5 and a clamp-screw 11 is employed in connection with each clip to bind against a side of said sill. The thimlilo-extension 10 of each clip is tightened on a stem 12 by means of a bolt and nut, the bolt; 13' being extended through cars 14: with which said thimble is provided. i Clip ends 15 oil a horizontal bar ltt are tightened on the stools 12 by means of bolts and nuts, each of said ends of the bar being provided with cars 17 through which the corresponding bolt. 18 is passed, and from the foregoing it. will be understood that; the bar 10 may be adjusted on said stems to vary distance between said hi and the harvester frame, as occasion may require for the alineinent 0t link-belt and sprocket-gear hereinatter more particularly speeitied.

The bar It) is provided with a hushed center hearing ti) tor a horizontal shank ex tension 20 ot a vertically tll l3t j0tl bow Q1, and a bore ot the bow and its shank is also hushed, the respective anti-'l:'riction bushings 2;, 2 being shown in Fig. 3. Extending through the bushing :23 is a spindle it last at one end, in a l)()r'tl" ..1ll.' pinion :25 and at the other end in a sprocket-whccl 2(5, a spacing collar 27 being interposed between the hub of the sproclcct-wheel and the bushing A link belt con ects the sprocket whccl era with a similar wheel 2*. that is in one piece with or otherwise rigidly connected to the sprocket-wheel 8 ol the cranksha tt 6 aforesaid. The how 91 and its shank 2t) constitute a swivel, the ends of said how being bearings 30 for an arbor ill on which vertical center eyes 39 of a frame 33 are 'lastened by set-screws 3 1 or other suitable means the frame being shown within the confines ot' the aforesaid bow. loose on the arbontitwithin the coniiues ot' the frame is a hovel-gear erown-' .vheel in mesh with lcl preferably channel-iren beams 39, and

other bearings l for an axle 41 of wheels 42 are provided in connection with the beams, these lit-ants, the axle and wheels thereon constituting a truck to which further ref-creme is made. in mesh with the C1'()\\11\\'l10l 3:) is another bevel-gear pinion 43 fast on a spindle 4:4: that has antifriction hearing in a hushinf that extends through a bore in the irame 33 and one of its 'trunnions. Normally loose on the spindle l-t' is a sprocket-wheel 46 corn hined with a clutch of any suitable construction the sliding element t? of. said clutch on said spindle being controlled by a lever 4-8 'tulrrtuaml in connection with an arm 49 of the frame 33 and arranged within convenient reach from the operators seat 50 of the harvester. h'lountcd on the truck aforesaid is a motor in the form of a gaso lene-engine having a s1u'oclachwheel 51 fast on its crankshaftand a. linlz-helt 53 connects this sprocket-wheel with the one 46 aforesaid.

From the foregoing it. will be readily understood that the frame 35) has free play on a vertical axis and the swivel-how 21 has like play on a horizontal axis, the two combining to form a universal-joint between the harvester and motor-rarrving truck to compensate for i'rregzjularities of surface over which said harvester and truck are traveled, and thus cramp in the gearing connecting the ll'lUtOl and the harvester machinery is, avoided, the crown-whee 35 being an idler connecting the pinions {t3 and 25 to transmit, motion from one to the other.

hen ground conditions are such that: the inai-l'i-wheel of the harvester cannot perform its function as a driver for the machinery of said harvester, as frequently happens in various localities, the power transmission between said main wheel and cranle shaftor otherwise of said imurhinery cut; out and the s 'a'octretovheel 4-6 clutched in connection with the spindle 44. How it the motor he started the power of same will he exerted to orive the harvester i'i'iachinery through the medium of the transmission gearing above specified, it lacing understood that said motor is non-effective as a means for propulsion of the harvester and the mo tor truck.

I claim:

it. A harvester, a truck, a universai-ioint;'

recess? face over which said harvester and truck are traveled and cramp in said gearing avoided 2. A harvester, clips embracing a sill of same, stems in connection with the clips, a

har fast on the stems, a truck, a universaljoint connecting the truck and said bar, motor carried by the truck, and clutch-controlled gearing connecting the motor with the harvester machinery through said joint by which compensation is had for irregug larities of surface over which said harvester and truck are traveled and cramp in said gearing avoided.

3. A harvester, clips embracing a Slll of same and having tlrimhlc-extensions, stems 35 fast in the thimhles, a bar fast on the stems, a truck, a universal-joint connecting the truck and said bar, a motor carried by the truck, and clutch-controlled gearing coni'iecting-the motor with the harvester ma ge chinery through said joint by which compensation is had for irregularities of surface over which said harvester and truck are traveled and cramp in said gearing "avoided.

saidhar, a motor carried by the truck, and

clutch-controlled gearing connecting the motor with the harvester machinery through said joint by which compensation is had for irregularities of surface over which said harvester and truck are traveled and crau'tp in said gearingavoided.

5. A harvest-er, a bar supported in connection with a sill of the harvcster frame, a vertically disposed bow having a central horizontal shank for which the bar is provided with a bearing, a frame in axial play connection with the bow to therewith constitute a universal-joint, a truck with which the frame has trunnion connection, a motor carried by the truck, and clutch-controlled gearing ct'i-nnecting the motor with the harvesterqnachinery through said oint, by which compensation 1s had for 1rregu-.

laritiesin the surface over which said-harvester and truck are traveledand cramping in said gearing avoided.

6. harvester, a bar supported in connection witn a sill. of the harvester frame and provided with a central bearing, a ver- -ticaliy disposed how having a central tuhular shank engaging said hearing, a spindle tending through the how and its shank, t cvel-gcar pinion fast on the spindle, linke t and sprocketgear connecting said spinwith the harvester machinery, an arbor 5-which the frame has trunnion connection at rightangles to the aforesaid arbor, a spindle extending through said frame and one of its trunnions, a bevel-gear pinion fast on the latter spindle in mesh wit-h the crownwheel, a motor carried by the truck, and clutch-controlled link-belt and sprocket gear connecting the motor with the last named spindle.

In testimony that I claim the foregoing I have hereunto set my hand at Port W ash- 15 ington in the county of Ozaukee and State of Wisconsin in the presence of two witnesses.
