WILLIAM ,A. COCKE, OF CARTERSVILLE, VIRGINIA.

S'IU'MP-PULLER.

To all whom it may concern:

Be it known'that 1, WILLIAM A. Coons, a citizen of the United States, residing at Cartersville, in the county of Cumberland and State of Virginia, have invented certain new and useful Improvements in Stump-Pullers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in stump pullers.

The object of this invention is to provide a machine equipped with novel means'for pulling stumps, roots or the like from the ground and also may be used as a lifting machine for raising heavy weights such as lumber, iron or the like and this machine is equipped with a mechanism whereby stumps may be pulled up or other materials lifted in a quick and reliable manner.

A still further object of this invention is to provide a stump pulling machine with a frame and having novel power applying mechanism arranged to be secured to the shaft for rotating the drums.

A still further object of this invention is to provide drums with novel means whereby the drums may be rotated in either direction.

A still further object of this invention is to provide a device of this character, which will be simple, practical and comparatively inexpensive in construction and one that can be manufactured and sold at a low cost.

With these and other objects in view, the invention consists in the novel combination and arrangement of parts hereinafter more fully described and set forth in the claims hereto appended.

Specification of Letters Patent.

Patented May 7, 1918.

Application filed April 20, 1917. Serial No. 163,437.

Fig. 7 is a fragmentary detail sectional view of the shaft and gear,

Fig. 8 is a fragmentary sectional. view illustrating the manner in which the movable roller is swivelly connected by one end in the frame.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

Referring to the drawings, the numeral 1 designates a rectangular frame in its entirety. The frame comprises a bottom rail 2, vertical end rails 3 and a tcp rail 4-.

The top rail f is provided adjacent one end with a longitudinally extending slot 5 which communicates with and extends outwardly through the opening 6 arranged therein.

The opening 6 is adapted to receive the screw threads 7 of the shaft 8, a handle formed on the outer end of the shaft 8 to facilitate the moving of the shaft inwardly or outwardly in the slot 5 in the top rail of the frame. The inner end of the shaft 8 is enlarged as at 10 and has secured thereto a bearing collar 11 the purpose of which will be hereinafter more fully described.

A rectangular closure plate 12 is secured over the slot 5 in the top rail 4 by suitable fastening means 13 as illustrated in Fig. 4 of the drawings.

A relatively stationary drum 14 is journaled in the bottom and top rails of the frame adjacent one end thereof and this drum carries a gear 15 which is located in wardly beyond and in close proximity to the top rail 4 as illustrated.

A relatively movable drum 16 is journaled in the bottom rail as at 17 and has its opposite ends journaled in the bearing 11 on the inner end of the shaft 8 as illustrated thus facilitating the adjustment of the relatively movable drum with relation to the stationary drum,

A pair of gears 18 of different diameters are secured to the relatively movable drum adjacent the upper end thereof and in close proximity to the inner face of the top rail 4: as illustrated.

A shaft 19 is rotatably mounted in the top and bottom rails centrally thereof and has its upper end projecting upwardly beyond the outer surface of the top rail as at 20 which terminates in-a reduced squared shank 21 which is adapted to receive an operating handle 2:2 thereon.

The gear 24 when rotated intone direction is adapted to mesh with the gears and 18 of the

drums

14 and 16 and when moved upward on the shaft 19 and the drum 16 is moved inwardly it is adapted to mesh with the gear 18 and gear 15 to cause rotation of the drum in different direction upon reverse rotation of the crank handle 22. p

The lower end of the relatively movable drum is provided with a trunnion which terminates in a ball 26 which ball is adapted torest in a bearing housing 27 removably secured to the exterior of the bottom rail 2.

' The inner surface of the bearing housing is provided with an inwardly tapering recess 28 which is adapted to receive the ball and the bottom rail is provided with an inwardly tapering opening which alines with the recess 28 to receive the ball 26 therein so as to permit pivotal movement of the relatively movable drum therein so as to facilitate the moving of the movable drum with relation to the stationary drum.

The drum 14 carrying the gear 15 and the drum 16 carrying the

gears

18 and 18 are arranged to have engagement with one another through the medium of the gear 24 which is carried by the shaft 19. The gear 24 when rotated downwardly on the shaft 19 engages the gear wheel 18 of the drum 16 and the gear 15 of the drum 14 and it is to be understood that the gear 18 is of. a larger diameter than the gear 15 carried by the drum 14 thereby upon rotation in one direction the drum 14 will make a greater speed and have more revolutions than the drum 16. hen the shaft is turned in the reverse direction the gear 24 moves upwardly, and the movable drum is moved inwardly thus meshing the gear 18' withthe gear 24 and the gear '15 whereby upon reverse rotation of the shaft the gear 18 being of a'smaller diameter than the gear 15 the drum 16 makes more revolutions than the drum '14, the purpose of which will be hereinafter more fully described.

A cable 29 has one end removably secured to the drum 14 as at 30 and its opposite 'end is wound about the drum 16 as at 31 and has a portion depending from the drumor extending laterally from the drums as at 32 whichis adapted to'receive'a pulley wheel 33 to "which is journaled a U-shaped yoke 34 having connected to its web portion and eye 35 a flexible cable 36 which isad'apted to be wound about a stump or placed'upon material which is moved upon rotation of the drums through the medium of the shaft '19 and "crank 22;

It can be understood that the drums Can be used in either a horizontal or vertical position depending upon the manner in which the device is to be used for moving. W'Vhen it is used as a stump puller, the drums can be set up in a vertical position and the cable 32 moved laterallytherefrom and connected to the stump which is designated PA in the drawings.

Vhen it is connected up with the stump in the manner described, the stump willbe easily and quickly lifted, due toithe fact that there is comparatively no slack-in the .cable as a constant pull is obtained by one drum being rotated faster than the opposite drum.

Now referring to Figs. and '6, wherein there is shown a power operating mechanism which facilitates the rotating, of the drum, by any suitable power source, there is illus' trated a frame 1, in which is a drum 14'and a movable roller drum 16. But insteadgof rotating the drums with the crank handle 22, there is secured tothe upper end of the shaft 19, a, gear 37 which is arranged on the squared portion of the shaft for rotation therewith.

The wheel 3-7 is a worm wheelora worm gear and is adapted to meshwith the worms 38 located on oppositefsides ,thereof and swivelly'connected as at 39 tothesupporting plate 40 which is secured toz-the toprail 4 .by suitable brackets 41. Theopposite ends of the worms 38 are pivotally-secured as a-t 42 to the arms of the Y-shapedlever' 43. A U-shaped frame 44isfsecured;by the' ends of its legs to the ioppositesideiedges .of'the'top rail 4 as at 45 and its web is providedioirits upper side with a plurality OfSPfl-CGClLilOtChQS 46 in which is adapt'ed' to'be fittedt'he lug 47 carried by the stem of the Y-shapedlever 43; A spring 48 is securedas at-49 to the under side of thestem of the lever 43' andzis adapt ed "to engagewthe web portion 44=of .theU- shaped member to normally retainzthe lug 47 on thestem of'the lever inone of the notches or recesses '46.

The supporting member .40 has journaled centrally therein a shaft '50" whichcarries the gear wheel centrallyof its endsdesig" nated 51, a pulley 52 is secured tol'the outer end of the shaft 5O whichis adapted'to re-' ceive a driving belt 53' :whichi'facilitates the rotating of theshaft and gear 51, a pair-0f smaller gears 53 are rotatably mounted on the member'4O2on opposite sides of thegear 51 and are adapted'toamesh therewitlr'and they have a sha'ft extending through and pivotally connected to the inner and lower ends'of thew'o'rms38 as at41.

When it is desired touse'the power driven device with my improved stump Ipuller. the handle 54 is grabbed and the stem :of the Y-shaped member 43 is moved either to the right or left to turn a respective worm into engagement with the gear 37 whereby upon rotation of the shaft through the medium of the pulley 52 the drums will be either rotated in the right or left direction.
