To all whom it may.con/cern:A

Be it known that I, BENJAMIN BURNETT STAUFFER, a citizen of the United States, and

a resident of Wichita, in the county of Sedgwick and 'State of Kansas, have invented a new Aand Improved Grain-Transferring Device, of which the following is a full, clear, and exact description.

The invention relates to self-feeders of threshing-machines, and -its object is to provide a new and improved transferring device or power-pitcher for carryin grain in the straw from a stack or the li e to the selffeeder oi the threshing-m achine in such a manner that the grain passes in an even uniform layer to the self-feeder to insure a continuous and proper feeding of the grain without the aid of manual labor'- The invention consists of novel features and parts and combinations of the same, which will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings,

forming a part of this specification, in which similar characters of referenceindicate corresponding parts in all the views.

Figures 1 and 2 are front and rear side elevations of the improvement. Fig. 3 is a plan view of the same. Fig. 4 -is` a sectional plan v iew of the same on the line 4 4-of Fig. 1. Fig. 5 is an enlarged sectional plan view of part of the improvement on the line 5 5 of Fig. 11 Fig. 6 is a transverse section of part of the shifting mechanism for the drums controlling-the grain-delivery forks, the section being onthe line 6 6 of Fig. 4. Fig. 7 is an enlarged side elevation of one of the hand-i Fig. 8 is an enlarged Vplan view of the pulley for the fork-rope, and Fig. 9 is an enlarged sectional` side elevation of the mechanism for adjusting the inclination of the discharging-conveyer. A The improved grain-transferring device is mounted on a wheeled vehicle A, having its body A' provided at the forward end with a water-tank A2 and a fuel-storage compart# ment A3, and on the middle rear portion of the said body A' is arranged a grain-receiving receptacle A", into which the ain in the straw is.delivered by the use of carriers B and B', preferably in the form of rain or hay forks of any approved construction. The re.- ceptaole A4 is open at the top and at the rear end, and in its bottom is arranged a horizontally-disposed endless belt and Slat conveyerl C, onto which falls the grain discharged by the carriers B and B', and the said conveyer C discharges at its rear end onto the lower end of an endless belt and Slat conveyer' D extendingV upwardly and rearwardly and which-serves to carry the grain upward and to discharge the saine in a continuous stream of uniform thickness into the usual self-feeder of a threshing-machine.

vIn order to ive the desired motion to the carriers B and and the conve ers C and D and to control the same, the ollowing arrangement is made: On the rear lower portion of the vehicle-body A is journaled a transversely extending driving shaft E, provided with a pulley E', connected by a belt E2 with a pulley on the threshin -machine, the said belt being normally slac and adapted to be tightened by a tightening device inthe form of friction-rollers F F', en-

gagingthe under side of the run ofthe' belt E2 adj aent to the pulley E. The frictionrolIersF and F' are journaledin a frame F2, mounted to swing loosely on the shaft E as a fulcrum, and the said frame F2 is connected by a link F3 with'v an arm F4, attached to a transversely-extending shaft F5,jou1"naled in suitable'bearings on the top rear ."portio'n of the vehicle-body A'.

the operator, and the said hand-lever F is desired position. By'the operater swinging 0n 'the shaft F5 is secured ahand-lever F under the control of the hand-lever F6 from the left to the'right (see Fig. 1) an upward motion is given -to the frame Fz to cause t 'e frictionrollersF and F to take up thc slack in the belt E2, and consequently when the threshing-machine is in motion the belt Ezfdrives the pulley E' and the main driving-shaft E.

When the hand-lever F6 is in the desired position after the' -belt is tightened, then the hand-lever is locked in place by the screw F7. When it is desiredto stop the rotary motion of the shaft. E, the screw F is loosened' and the hand-lever F is swung from theV right to' the left to swing the frame F2 downward to allow the belt E? to run slack relative to the pulley E', so that the shaft E comes Yto a stop. Thus by the operator 'manipulating the lever F the shaft E is started or stopped.4

On the shait E (see Fig. 4) are secured pin' Y ions E3 E, adapted to mesh with earwheels G and G' on drums G2 G3, on W 'ch wind fork-ropes B2 and B3, carrying the IOO G and G', and the lowering of the carriers,

`latc forks of the carriers B and B', as lainly illustratedin the drawin s. The for -ropes B2 and Ba after leaving t e drums G and G pass over guide-pulleys B4 and4 B5to then ex- 5 tend upwardly through hollow posts H and H', journaled in suitable bearin sy on opposite sides of vehicle-body the said posts H and H carrying at their upper lends glide-pulleys B5 for guidin the fork-ropes 2.downwardly and forwar ly to guide-pulleys B7, journaled-in the outer ends of booms I and I', pivoted at their inner ends on arms I3, secured to the posts H and H, so as to turn with the same. By turning the posts 5H and H the booms I and I can be swung around in such a manner as to carry the carriers B and B and their loads from the stack over the receptacle A4 for the carriers to then discharge their loads into the receptacle A* and onto the conveyer C, arranged in the bottom of the receptacle. It is understood that either or both of the carriers B and B can be used for carrying grain from stacks on opposite sides of the machine, or only one of the carriers may be used'iior carryin grain from a stack located on ,onev side of t e machine. The carriers B and B are of usual construction and are manipulated in the usual manner, so that further description ofthe same 3 l is not deemed necessa In order t'o cause tage, ropes B2 and Bito raise the carriersB and B', it is necessary to rotate the drums G2 and Gs in one direction b power obtained from the shaft E by wa o? the pinions E3 and E4 and the gear-whee s with or without their loads, is accom lished by throwingzthe gear-wheels G and G out of f mesh with the pinions E5 and E* to allow the drums G and G5 to rotate freely. For the purpose mentioned the shafts G4 and G5 of the drums G2 and G5 are journaled at their outer ends in fixed bearings and at their inner ends in Abearings G G7, mounted to slide longitudinally, asplanly indicated in Fig. 4. The shafts lG and G5 are connected h links J and J with transversely-extending evers J 7 and J5, ulcrumed on the vehicle-body A',

and the outer ends of the said levers J 2 and J5 are connectedwithupwardly-extendinghandlevers J* and J5, (see Figs, 1, 4, 5, 6, andy 7,) likewise fulcrumed on the vehicle-body A. vThe upper ends of the Vhand-levers J* and J5 are rovided with the vusual hand-controlled s J5, engaging segments J7, so as to hold the hand-levers J* and J5 in thedesired position. Ifdesired, the latches J may be thrown out of engagement with the segments J7 by the operator manipulating foot-levers l (Shown in Figs. 5 and 7.) This is especiallg desirable whenever the operators han s are otherwise en aged. When either of thehand-levers J* or5 is thrown from the left to the right, then the corresponding lever -s J or J gestemd t0 Shift the Shaft-Gf' i G5 with a View to throw the correspon wheel G or G in mesh with the pinion E3 or E4 to rotate the drum G2 or G2 by power from the driven shaft E with a view to wind up the fork-rope B2 or B3, and conse uently to raise the carrier B or B and its loa to the desired height. b When it is desired to lower the carrier B or B, the operator swings the corresondinghand-lever J 2 or J5 from the right .to t e left to move the gear-wheels G and 'G out of mesh with the pinions .E3 and E* to allow free rotation of the drums G2 and G3 for the ropes B2 and B5 to unwind from the drums by the weight ofthe carriers B and B and their loads. The drums G2 and G5 during the unwinding ofthe ropes B2 and B3 may be braked by moving the gear-wheels G and G vn engagement with brake-blocks G8 and G", (see Fig. 4,) attached to the vehicle-body A.- The lower end of each post H fits onto a tubular bearing K attached to a bracket K, in which the guide-pulley B5 is journaled (Sec Figs. land 8.)

In order to turn the posts H and H with a view to swing the' booms I and I around, the following device is provided: 0n the posts Il and H wind endless ropes I-Iand H3, (see Fig. 5,) which also wind on 'drums H4 and H5, the rope H2 assing directly from the post H to the drum while the rope H3 passes from 95 the vpost over guide-pulleys H5 to its drum H5.

On the 'drums H't and -H5 are.. secured gearwheels H7 and H2, of which the gear-wheel H7` ding gearis adapted to mesh with either of the gearlwheels L or L, andlthe gear-wheel H8 is adapted to mesh with either of the gearwheels L2' or L3. (See Fig. 5.)l wheels Land L2 are secured on a shaft L, while the gear-wheels L andLa are secured on a'shaft L5. On the shaft L4 is secured a pulley L, connected by a belt L7 (see Fig. 1) with a 4pulley Ls on the main driving-shaft E,

The ge arso. that when the latter is `rotated, as previously exlplained, a rotary motion is given to the shaft which in turn rotates the gear- Wheels L and L?. The shaft L5 is rotated from the shaft L4, but in a reverse direction, and for this pu ose a pulley L? is secured on theshaft L4l an connected by a crossed belt Llo with a pulley L", secured on the shaft L5. Thus when the shaft L4 is rotated the shaft L5, as well vas the gear-wheels L and L2, are turned; but when'the gear-wheels H7 and H8' are in mesh withithe gear-wheels L and I r2 the drums H and H5 are rotated in one direction, and when the gear-wheels H7 and H2 are in mesh with the ear-wheels L and La then the drums L* and 5 are rotated in the opposite' direction. In order to shift the gear-wheels H"` and H asi'described, the shafts H9 and lH10 of the drums H and H5 are journaled at one end Vin iixed bearingsand at their other ends in slidable bearings Hn and H, (indicated in Fig. 5,) similar to the, bearings G and G7,y previously mentioned. -The shafts lic rif

IIC

- H and H are connected by links N and N' with hand-levers N2 and N3, adapted to be. locked by the usual latches with segments N4, attached to the vehicle-body A', and. by throwing either of the levers N 2 or N3, say, to the right the gear-wheels H7 and H8 are moved in mesh with the gear-Wheels L and l to rotate the drums H4 and Irl5 and the posts H and H' in one direction., and when the operator throws the lever N2 or N from the right to the left the gear-wheels H7 and H8 are moved in mesh with the gear-wheels L and L3, so that the drums H4 and H5 and the posts H an d H' are turned in an opposite direction. Thus Vthe booms l and I' can be, readily swung from the stack over the receptacle A* and back from the latter to the, stack. (See full and dotted lines in Fig. 3.)

The conveyers C and D are driven from the shaft E by the following mechanism, special reference being had to Figs. 1, 2, and 4: On

' the shaft E is secured a pulley O, connected by the sha a crossed belt O' with a pulley O2, secured onl a shaft P, journaledin suitable bearings on one side oi' the vehicle-body A'. (See Figs 2 and 4.) The belt O' is normally slack and is adapted to be tightened by friction-rollers C3; journaled on a lever 04, f ulcrumed at one end on the vehiclebody A' and pressed on at its other end by a spring O5 to normally hold the lever i()4 and the friction-rollers O3 in a non-. engaging positionrelative to the belt O'to leave the latter slack. The free end of the lever O* is also connected with one end of a rope O, extending over several guide-pulleys O7 to connect with a hand-lever O8, fulcrumed on the vehicle-body A' and provided with the usual latch O, engaging a segment Oo for locking the hand-lever Cs in the desired osition. Y When it is desired to drive P from the shaft E, the o erator unlocks the hand-lever O8 by with rawing the latch 0 and then swings the hand-lever over to exert a pull on the rope O to swing the lever O4 into an active position-that is, for the friction-rollers O3 to tighten the vbelt O. Thus when the shaft E is driven and the belt O' is tightened a rotary motion is given to the shaft P. On'thev shaft' P is secured a cone-pulley P', connected by abelt P2 with a cone-pulley P3, securedon one end of the shaft C', forming part ofthe endless belt and slat conveyer C, the said shaft C carryiing the usual sprocket-wheel C2, over which passes a sprocket-chain C3, carrying-the slats and belt of the conveyer C. Cn the shaft P is also secured a sprocket-wheel P, connected by a sprocket-chain P5 with a sprocket-wheel' P, secured on one end of a shaft D', formingpart of the belt and slat conveyer D, so that when the-shaft P is rotated from the shaft E, as previously mentioned, then the conveyers C and D4 are simultaneously set in i,riotiori, the conveyer C being, however, driven at alower rate of speed than. the c'onveyer D.l

In or'der -to give the desired inclination to the conveyer D, the side frame thereof is 4connected with the ends of a rope Q, extend# ing to and Winding on a shaft Q', journaled in suitable bearings on the rear top portion of the vehicle-body A'. On the shaft Qis secured a worm-wheel Q2 (sec Figs. 3 and 9) in mesh with a worm-wheel Q3, carrying on its shaft Q4 a handle under thc control oi' the operator. Now'by the operator turning the handle 5 the worm-wheel Q3, and consequently t e-worm-wheel Q2 and the shaft @5, are turned to wind up or unwind the rope Q according to the direction in which the handle Q5 is turned. By winding up the rope Q on the shaft Q' more inclination -is given to the conveyer D, and by unwindingthe rope Q less inclination is given to the said conveyer. Thus by the arrangement described the upper end of the conveyer can be readily brought in proper relation to the I self-feeder of the threshing-machine to insure a pro er discharge of the grain from the conveyer to the said self-feeder. lt is understood that by having the Worm and Worm-wheel Q3 and Q2 the shaft Q.' remains locked after the desired adjustment of the conveyer D is made. lt is also understood that a. portion ofthe grain during its upward travel on the conveyer D has a tendency to fall backward, so as to insure the delivery of a layer of grain from the upper end of the conveyer of a uniform'thickness, and in order to aid in the formation of this uniform layer of grain stri pingforks R are provided, mounted to oscillate at or near the u' per portion of the conveyer D. The oscillatlng forks vR are fulcrumed at R' .on .links R2, mounted to swing on a ixed rod R3, sup orted by the frame of the conveyer D, and t e forks R are engaged by the crank-arms R4 of a shaft R5,

carrying a ulley S, connected by'a belt S' l Witha pnl ey S2, securedon theshaft D2,

-orming partv of theconveyer D, and located at the uv er end thereof, as plainly illus-l trated in igs. 1 and`3. Thus when theconveyer D is' in action and the shaft D2 1s rotated a rotary motion is' transmitted to the shaft R5' by the'pulleys S and S2 andthe. belt S', and this rotary motion' of the shaft causes an oscillating motion of the forks R.

As the forks' oscillate they move surplus grain moving upward on the conveyer-belt D in'a downward direction, so that a continuous layer of grain of uniform thickness 'is I zo discharged at the upper end of the conveyer into the self-feeder of rthe .threshing-mafl chine.' y

The operation is as follows: The grain 1n the straw and stacked on one or both sides of the transferring device is 'carried -romthe stack`by the use of either or both carriers and B' into the receptacle'A, in which it 1s transferred rearwardly by the conveyer C, which discharges the grain onto the inclined water and fuel, and hence the usual tender" conveyer D. As the grain is carried upward on this conveyer D it forms into' an even layer of a uniform thickness, as previousl described, the formation of the layer eing aided by the oscillating forks R. The uniform layer of grainis discharged from the upper end of the conveyer D directly into the sel -feeder of the threshing-machine in an uninterrupted stream, so that a pro er and quick threshing of the grain takes p ace and without requiring an manual laborlfwhatever in directly mampulating the grain, as-

'the conveyer D it is evident that suficient grain is always delivered to the lower end of the conveyerV D to form the layer of uniform thickness, especially as some of the grain carried up by the conveyer D falls backward. By' providing the transferrin the water-tank A2 and the fue -storage compartment A3 a tender is provided'for supplylng the boiler of the threshing-machine with employed can `beentirely'dis ensed with.

Instead of using the pinionsv E* and thev gear-wheels G G suitable friction-fwheels may be emplo ed to allow starting of the oarriers B Bwitliout. jerk or jar.
