HOISTING- AND SCC'RAW-CONVEYING MACHINE.

Application filed August 2, 1921. Serial No. 489,299.

To /7! i k/"mm it maycoerce/'22.:

iie it known that we, 'llmnrarv Si. lVooD and ILL-1AM T. Vfoon, citizens of the United titates. residing at lVit-hita. in the county of fi'iedgwick. and State of Kansas have invented certain new and useful Improvements in a Hoisting and Straw-Conveying Machine of which the following is a description. referring to the drawings which accompai'i i' this specification.

T he invention relates particularl to a hoisting machine, adaptable for combination as an independent unit with vehicular supports. such as wagons. trucks, separators and the like: or on stationary supports; in the construction illustrated the machine is shown in combination with a threshing machine with the ordinary hay fork operated by the hoist depositing wheat or other grain straw upon the conveyor for threshing operations. it will be understood. however, that devices other than the hay fork are employed for handling other commodities or materials. Other and specific improvements will. be des igl'nated in the description of the drawings, in which, Fig. 1 represents a plan view of the machine. Fig. 2 is a side elevation of Pi l looking in the direction of the arrow. FM- 2 a front elevation of Fig.1. Fig. 4 is a side view of a brake element in combination with and for locking a cable reeling drum, shown in section. Fig. 5 is a top view of l i g. 4. Fig. 6 is a perspective view of the lever operating means controlling clutch en-- ga treincnt intermediate the driving shaft and a cable reeling drum. Fig. 7 is a perspective view of the lever operating means for engaging and reversing the action of the friction beveled drive mechanism for swingiii-1Q the boom. F S is a sectional view taken through the slidable driven shaft of a friction bevel driving mechanism along the line 88, Fig. 3 looking in the direction of the arrow. Fig. 9 is a view taken along the line 99, Fig. Similar numerals of reference indicate corresponding parts throughout all the figures of the drawings.

flefkzisiing to the drawings, the base fra1n ing elements 11 of the machine may be mounted on any suitable supporting surface or platform 12. which may be embodied in a support such as the separator 13 having a conveyor 14. The drive wheel 15 of the ma chine may be driven by a belt 16 driven from an engine, motor or other power developing means The wheel 15 is loose on the main shaft 17 of the machine. T he shaft 17 is mounted in the bearings 18, 18 on the frame 11. Asmall sprocket wheel 19 rigid with the wheel 15, drives a sprocket chain 20 leading around the larger sprocket wheel 21 fixedly fastened to the shaft 22 mounted in a bearing 23 on the frame 11. A smaller sprocket wheel 24 rigid "with the shaft 22 carries a chain 25 driving a larger sprocket rigid with the shaft 17 for power and speed reduction purposes. The shaft 17 furnishes power for driving twin sets of mechanism operable, each independent of the other, for the purposes of the invention and arranged at up posite ends of the machine as illustrated in Figs. 1 and 4. A chain 26 driven from a sprocket rigid with the shaft 17 intermediate the twin sets of mechanism drives a sprocket rigid with the shaft 27 which is mounted in bearings 28, 28 on theframe ll also intermediate said twin sets and functionable in common with either of said sets independent of the other.

A description of the mechanism shown at the left of Fig. 3 neXt follows it being understood that the twin set at the right thereof functions in a similar manner. Arable reeling drum 29 is loosely mounted on the shaft 17. A cone clutch 3O slidably mounted on a keyway (not shown) on the shaft 17 is engageable or disengageable with a functioniru; clutch face on said drum 29 for reel ing the cable 31. A. lever handle 32 rigid with a shaft supported in bearings 34, 84 on the frame 11 operates the forked crank 35 ri.

id with the shaft 33. The crank 35 res a pin 36 rigid with a rocker shaft mounted in bearings 38 in the frame 11 and carrying a forked arm 39 engaging in the ring slot of the clutch 30. By moving the handle 32 forward or back as indicated by its dotted are movement Fig. 1 the clutch 30 engages with or disengages from the drum 29. The vertical mast 40 is rotatably arranged and supported in bearings carried by memljiers 41. 42 supported from the frame 11. A boom 43 pivotally mounted at 44 to a collar rigid with the mast 40 is secured also by the cable 45 at a desired inclination to the mast.

When the clutch 30 engages the drum 29, the cable 31 carried by the boom 43 is reeled up to raise the hayfork 46 and straw or other load carried by the cable 31, to a desired, height, when the clutch is released and a lever 47 pivoted at -48 on the frame 11 is simultaneously drawn rearwardly as indicated by the arrow Fig; 4 and whereby the brake band 49, connecting by members 50, 51 to the lever i? is tightened on the drum 29 to maintain the load at the desired reeled position.

It is now desirable to rotate the boom through the are indicated in Fig. 1 to depositthe load from the member e115 on the conveyor let or other dump. The sh ft 52 mounted in bearings :53 in the frame 11 car'- ries a crank 5:: therewith. fa forked shittin lever 55 connects piyotally at 56 with. it e crank by means of the rod 5?. The forks of the lever 5.3 engage a grooved collar. rigid with a shat't F39 rotatably and slidably mounted endwise in the outer bearing 60. The inner end of the shaft 59 is squared as at 61 to slidably engage tor endwise movement with the square hole or seat axially aligned in the outer end of the driven shaft 27.

Pressing on the "foot pedal 62 rigid with the shaft operates to move the lever 55 the collar 58 and the shaft F29 to the right, Fig. 3 and from the neutral position there indicated the truncated conical friction drum 63 would then engage the beveled periphery oi the friction wheel 64 rigidly mounted on the base oi the mast 40 and whereby rotation of the shaft 27 would transmit are rotation of the boom 53 in one direction; similarly pressing down on the foot pedal 65 would operate to move the companion friction drum 66 to ei'igage the wheel 6a for boom 43 rotation in the oppo site direction. The set at the right of Fig. 3 as stated operates in a similar manner and trame'a main driven shaft arranged in be'arings thereiinnn auxiliary shaft in p rallelism therewith and in bearings in the amea square holes axially aligned in the opposite ends of said shaft, central dri-Yinn; means operatively engaging intermediate said shafts; twin sets of hoisting" mechanism arranged one set on either side 0t said central driving means, each set comprising a cable reeling drum loosely mounted on the main shaft, a clutch and clutch means tor engaging said drum to the main shaft and brake means cooperating with the drum; a vertical mast rotatable in said frame, a boom pivotally supported from the mast, a cable carried by the boom engaging the drum; a shittable shaft in bearings in the frame and having a square end portion slidably mounted within the adjacent squarehole of the auxiliary shaft; a beveled friction driving;- mechanism intermediate and in combination with said mast and slidable shaftand means for transmitting desired endwise movement to said slidable shaft.
