Q STEAM-DRIVEN COMBINED HEAISIN'G ANn :inREsHiNG MACHINE.

To all 'whom/it concern:

.Be it known that I, LEWIS K. BROWN, a

citizen of the United States, residing at` Asotin, in the county of Asotin and vState of lWashington, have invented new and useful Improvements in Steam-Driven Combined Heading and Threshing Machines, of

-whicli thefollowing is a specification.

This invention relates to a steam driven combined harvesting and threshing? machine embodying in its general organization a rea ing device and a threshing, separating an cleaning mechanism to-which `the ma` terial cut by the reaper is delivered by suitable conveyers which are continuously driven during operation of the machine together with power engines carried on the machine 'for propelling the latter from the ground and for driving the reaping, conveying, threshing, separating and cleaning mechanisms.

The invention has for its objects to provide a comparatively simple, inexpensive machine of'this type whereby the grain will be harvested during forward travel of the machine over the ground and delivered onto the conveyers, one wherein the latter will be properly and continuously driven. for carrying the grain to the threshin mechanism, one innwhich the operation o .the various `mechanisms may be controlled at will and this irrespective of the machine being at rest or in motion over the ground, and one which will travel in its own swath throughs. field without treading down any .of the-standing gram.

AV further 'object of the invention is tof provide an improved light-weight portable mechanism for -separating the grain from the straw, and to. reclean the grain after it passes the ordinary sh'oe and before it passes from the machine.l I

A further object .of the invention is to provide a siinplifiedpropelling mechanism for driving the machine in its travel over the ground, together with means for steering the machine and yieldably supporting `the framework of the latter which inl turn sustains Athe engines and-attendant parts.

l/Vith these and other objects in view, the invention comprises thc novel features` of construction and combination of parts more,

.fully hereinafter described.

In the accompanying drawings: Figurer is a side elevation of a harvesting and threshing machine embodying the invention.

Fig. 1li is aplan view on an enlarged scale of a portion of the sickle blade, together with lits operating lever. Fig, 15 is a` detail `view,- pai'tly in yvertical cross section and on an enlarged scale, of the sickle bar and its -attendant parts. Fig. 16 is a detail front ele-A vation'of the sickle blade as viewed in the direction 'of the arrow in Fig. 15, and shows the sickle drive in detail. i

Referring'to the drawings,'it will be seen vthat the machine, the frame of which includes a horizontal table 1, is mounted for transportation o n a Vrunning gear comprising a rear axle 2- equipped with transporting wheels 3 and a front axle 4 having pivoted end portions or sections G adapted to swing on a horizontal plane and on which are keyed the front transporting wheelsv 5, having hubs set out, bringing the wheel l'ieaings under the boxings 7 or sleeves, Fig. 7. These sleeves have upwardly and downwardly extending arms 'Ta terminating in pivots 7 that turn in bearingsi'c on the housing 61, which Alatter .carries the weight of the front end of the platform 1. To the sleeves, which swing uniform movement by a link 9, and pivoted von vertical axes by the pivots 7b, are fixed linwardly and rearwardly projecting arms 'having their forward ends connected for y to one of the arms is a rack bar 10, the teeth 11 of which are in mesh with a pinion 12 in turn fixed at the lower end of a vertical steering post 13. This post rotates in a bearing 121 on the housing 61 and has fixed on its Vupper end a hand wheel 14 through the me-A reaper frame 17 adapted to swing in a verti cal plane toward and from the ground surface and to be normally supported in elevated condition through the supporting members or beams 18 pivoted to the platform and provided at their forward ends with shoes or runners 19 which travel on the ground surface, there being fixed to the bars 18 vertically uprising standards 20 which proj ect upward through the guides 21 on the back of the frame 17. The upper ends ofthe standards are toothed to form racks a and are connected together by means of a shaft b sustained at the top of the rear portion of the platform 17, there being fixed on the ends of the shaft pinions c, meshing with the racks a and serving to maintain 'the outer ends of the frame 17 at equal distances from the ground, while the height of the sickle on the balanced platform 17 is regulated by means of a bevel gear d fixed on the shaft b and engaged by a bevel pinion e carried by a shaft f arranged counter to the shaft I) and extended rearward to the operators platform and provided at its rear end Witha crank wheel g adapting the parts for convenient operation.

Journaled in bearings 22 in the frame 17 is a rotary reel shaft 23 carrying a rotary feeding reel 24 which in practice directs the grain or other material to be cut inward between the fingers of a stationary sickle bar 25 sustained at the front of the reaper frame and coperating with a reciprocatory sickle blade 26 for reaping the grain in the usual manner, while pivoted intermediate its ends between a pair of vertical bearing standards 27 is a balance beam 28 provided at its rear end with a weight 29 and having its forward I end connected by a link 30 with the rear side of the reaper frame 17 for balancing the latter.

Extending longitudinally of the frame 17 is a pair of endless conveyor belts 31, 32, of

which the former travels upon rollers 33 andv 34 journaled in the frame, while the belt 32 is arranged for travel on rollers 35 and 36, the belts 31 and 32, which are spaced apart at their inner ends, being so connected for operation that their top portions travel toward one another, while sustained at one side of the platform 1 and extending longitudinally thereof is a rearwardly and upward ly inclined conveyer belt 38 having its forward end positioned in the space between the inner ends of the belts 31, 32, for receiving material therefrom, the rear end of the belt 38, which is arranged for travel over rollers 39 and 40, being disposed for delivering material through the opening 41 into the casing 42 of a threshing mechanism sustainedat the rear of the platform 1. The portion of the forward end of the belt 38 .which lies between the ends of belts 31 and 32 is held for travel in a horizontal plane by means of idler rollers 43, as seen more clearly in Figs. 12 and 13.

vArranged beneath the platform 1 is a Water tank 44 designed to render, the platform more rigid and to carry water for feeding a boiler 45 sustained on the platform and in turn connected by means o f a pipe 46 with an engine 47 and by a steam pipe 48 with a pair of' engines 49, ,both of which are connected for driving a main power shaft 50 on `which is fixed a pinion 51 in mesh with a gear 52 fixed upon a second driving shaft 53' arranged vertically beneathy and for operation from the shaft 50 on which there is also fixed a fly wheel 54, while fixed on the shaft 53 is a sprocket pinion 55, connected by a chain 56 with a sprocket gear 57 arrangedv on the front axle 4 for driving 'the latter, there being also fixed on the shaft 53 a. sprocket pinion 58 connected by a chain 59 with a sprocket gear 60 on the rear axle 2 forndriving the same. It is to be observed in -this connection that the gear 57 on the frontaxle is housed in a metal casing 61 which carries the front end of the platform 1 on its gudgeons 61 and that the rear axle 2 extends through a tubular casing 62 extended transversely through the tank 44 and serving to relieve said axle from contact with the water in the tank, and to form an adequate space in which the shaft operates, while at the forward end of the tank is formed a housing for the counter shaft 53 and itsattendant gearing and bearings, these parts being all fastened together in one piece, thus rendering the platform rigid. It is to be observed in this connection that the platform 1 extends at its forward end over the housing 61 and that the tank '44 is y a sleeve 67 arranged or rotation on the axle l 4 and independently' thereof, it being underpermitting'proper differential rotation of stoodthat thev aXle-isconnected for driving one'of the front wheels whiley the other of said wheels turns with the sleeve, this arL rangement being for' thel usual purpose of the wheels inthe operations of turning and guiding the machine.

v Extended longitudinally of the reaper frame 17 and journaled in suitable bearings at the rear thereof is a shaft 68 geared by a chain 69, 4arranged on suitable sprockets,4 with the reel shaft 23 for rotating thereel` and also connected by'a cross belt 70 with a shaft 71 from which the conveyer 38 is driven by means of a chain belt 72 leading to the shaft 7 3 of the roller 40, there being fixed on the shaft 71 a bevel gear 74 in mesh with a pinion 7 5 fixed upon and for driving a countershaft 76 which is in turn connected by a chain belt 77 with ythe shaft of roller 36 Yfor driving Vthe conveyer-32. The' conyeyer 31 is driven through the medium of a cross belt 76', Figs. 2 and 11, from a pulley on 76 tocountershaft 76 above, thence by 'sprocket cha-in 77` to roller 34, while the shaft 71 is drivenby means of a chain belt 78 from a countershaft 79 in turn geared through the medium of a chain belt 80 with the main drive `shaft 50. The belt 80 is arranged for travel upon a suitable sprocket wheel on the shaft 79 and a corresponding sprocket 81 mounted idly on the shaft 50,

the last named sprocket being provided with a hub 82 having clutch teeth in normal engagement with corresponding teeth formed hell crank lever,

.on the hub 83 of the fly wheel 54, as seen more clearly in Fig. 10, there being coiled upon the outer end of shaft 50 a compressible spring 84 designed to act upon the sprocket 81 for maintaining the clutch teeth thereon in engagement with the clutch teeth on the hub 83. It will be observed in, this connection that during reverse rotation of the shaft 50 in' the operation of backing the l machine the clutch member 83 may turn independently ofthe sprocket 81, thereby automatically throwing the reaping mechanism and conve ers out ofaction K n The movab e sickle blade 26 is reciprocated through the medium of va bell crank lever 85 fulcrumed atits elbow as at 86, and having one of its arms" engaged with the blade and its other arm connected by means of a link 87 with an eccentric head`88 'fixed on the shaft 71 and having a wristpin 89 engaged with the rear end ofthe rod 87 it being understood that as the rshaft 71 re-i volves the pitman rod 87 will. `actuate the which in turn will reciprocate the sickle blade. y

The :threshing mechanism, which ishoused in thercasing 42 includes athresher cylinder teeth 92 fixed in the perforated grain bed 93 above 'which there is also arranged a plurality of beater cylinders or drums 94.-

equi'pped with teeth 95 and adapted to act upon the grain after it passes beyond the action of the thresher cylinder 90, the cylinders 94 being connebted for rotation one from another through the medium of an' endless sprocket belt 96 arranged for travel around sprocket wheels fixed on the ends of the cylinder shafts andA to be driven from the slaaft 97 of the engine-47 by means of a belt 98 arranged for travel on a belt wheel 99 fixed on the engine shaft and a belt pulley 100 fixed on the shaft of one ofthe `cylinders while the thresher cylinder 90 is driven from the shaft 97 through the medium -of a belt 101 arranged for travel on a belty wheel 102 fixed on the shaft 97 andon a belt `pulley 103 fixed on the shaftof cylinder 90, it being understood, of course, that while the engine is inthe operation of driving the'shaft 97, the` clined chute 104 while a rreversely inclinedl` chute 105 is also arranged beneath the bed under the beating rollers 94. The' .chutes 104- and 105 are connected for uniform move 'ment by means of a bell crank lever 106 and further sustained for oscillation in the casing by means of links 107, the chutes being adapted to deliver the grain onto the upper end of a downwardly and rearwardly inclined screen 108 having a finely perforated forward portion 109 and acoarsely perforated rear portion 110 beneath which latter-there is disposed adownwardly and forwardly inclined pan 111 adapted to direct the material into an underlying conveyer trough 112 containing a tailings conveyer screw 113, the material passing through the por-tion 109 of kthe screen being in like manner directed to an underlying conveyer trough 114, containingV a conveyer screw 115, by means ofV asys- `tem of underlyinginclined pans and screens 116, 117, 118, and 119 and of which the pans 111, V116 and 118 are composed of metal. If desired, there maybe arranged in the casing 42 just above the delivery end of the con: veyer 38, a beater144'driven from the shaft 73 by a belt 144. r l Y Mounted on the outer face of the rear side wallv of the casing 42 and having communication with the latter is 'a pair of conveyer ducts and 121, of which the former communicates at its' lower end with the conveyer trough 112 andelevates the tailings back to Y the threshing cylinder 90 through thel mel dium of a spout 122, while the duct 121 com muiiicates at its lower end with the tiougli 114 which takes the clean 'grain to the sacker to be cared for.

Fixed on the shaft of the Central beater roller 04 is a pulley 131 to which is ecceiitrically pivoted a pair of pitinen 1252 and 133, of which the pitnian 1232 is connected with a crank arin 1I32f in turn fixed on a shaft 132" carrying the triple crank 106, while the pitman 133 is connected with a crank 133 crank 134 for osciliating screens 11T, 11S) and pan 118. rIhe conveyers 1125 and 115` and the elevators are driven by convenient pulleys on the projecting shafts througii the beatersv94,'while disposed for rotation iii the threslier casing 42 and to direct a blast of air onto the screens is a. fan 141 in turn inclosed within a fan casing 142 fand coniiected to be driven from the right hand beater roller. 94 through the medium of a crossed belt 143.

The platform 1, which carries the engines, boiler and attendant parts, is yieldably sustained at its forward end through the inediuin of vertically coinpressible supporting springs 146, which by means of interposed boxing rest on the gudgeons 61 and at its rear end by means of similar springs 147 which bear at their upper ends beneath members or rails 148 and at their lower ends upon bearing levers 149 in which the rear axle 2 is journaled and which are in turn pivoted at their forward ends as lat 150 to the frame of the machine and mounted at their rear ends upon vertical guide members or bolts 151, as'seen more clearly in Fig. 6.

The device connecting t-lie bell crank S5 with the sickle is shown clearly in Figs. 14, 5 and 16. In Fig. 15 is shown how the plate portion of the bell crank S5 passes through the breast of the reaper platform and extends out under the sickle bar 152 and has the adjustable parts 153 bolted thereon. Fig. 16 shows how the sickle bar 152 yhaving the cutting sections 26. attached may be in tw-o pieces abutting together as at 154, the two sections of the sickle bar being bolted between 155 and 156 as shown, 155 having a boss onethe lower side which is engaged by the adjustable pieces The pieces 153 are fastened to the plate S5 by means of cap screws 157 passing through slotted holes in 85" and screwed into the pieces 153, and by the taper bolts 15S passing through slotted holes in the pieces 153 and the plate S5. vThe slotted holes are shown by the dotted `lines in Fig. 16. The 'pieces 153 engaging the boss on 155 may be adjusted to take up all lost motion or looseness causing jar of the working parts by ytightening' the tapering bolts 15S.

i In practice, the engines having been setin motion, the machine will travel over the ground and they reaping, conveying and .fixed on shaft 133" carrying athreshing devices will bedriven through the medium of the various sets of gearing, as heretofore eXpla1ned. As the machine advances, the sickle blade 26 will cut the grain or other material, which will fall onto the conveyers 31 and 32 from which it is received by the conveyei' 3S and delivered thereby into the casing 42 through the opening 41. After entering the casing the grain tirs-t passes under and is subjected to the action of the thiesher cylinder 90 and thereafter to the action of the beater cylinders 94,

-whereby they grains will be effectually removed froin the slieaths, the straw finally passing into the s tiaw receivingv chamber 152 at. the rear end of the casing 42. The grain falls as usual through the perforated bed 93 onto the chutes .104 .and 105 and thence passes to the underlying screens and pans. Upon falling onto the screen 108 the clear grain passes through the. portion 109 of saidscreen onto the underlying system of screens and pans by which it is finally delivered into the trough 114 and carried therefrom by the screw 115 into the conveyer duct 121 for final delivery into grainl sacks.

-The coarser particles of material falling onto the screen 108 pass onto the portion 110 thereof through which it isdelivered to the underlying pan 111 and directed by the lat ter into the trough 112 from which it is conveyed by the screw 113 into the duct 120, thence carried back to the cylinder 90 for rethreshing.

It `is to be noted that during forward movement of the machine the clutch mem.

bers 82 and 83 formed respectively on the Asprocket pinion 81 and wheel 54 Will be maintained in engagement by the spring 84.but that when it becomes necessary to back the machine i'n the operations of turning or the like the spring 84 will be coinpressed, lthus permitting the teeth of the clutch member 82 to ride idly over the teeth ofthe companion clutch member, `\whereby the mechanism for driving the harvesting vand conveying devices will be thrown out of action, it beingunderstood that the threshing mechanism is independently thrown out of action by stopping the engines 47.

It is to be understood that any engine or motor of sufficient power may be placed ony the abovedescribed platform and connected to the machinery for operating the same.

Having thus described the invention, what I claim is L 1. The combination of a wheelsupported frame, runners or ground-engaging members extending forwardly therefrom, a reaper frame extending transversely in front of the irst-mentioneiil frame,` upwardly-extending members on the runners, rack bars on the members, guides .on the reaper frame for receiving the members, piiiions engaging the rack bars, and means for actuating the -pinl ions for I f from and supportedI on the runners and lomeans on the frame ,operating through the,
