WILLIAM WINESBUBG, OF BRISTOW, OKLAHOMA.

POWER-DRIVEN "WINCH.

Application filed May 24,

To all whom it may concern:

Be it known that I, VILLIAM VVINESBURG, a citizen of the United States, residing at Bristow, in the county of Greek and State of Oklahoma, have invented certain new and useful Improvements in Power-Driven lVinches, of which the following is a specification.

This invention relates to power operated winches.

The primary object of this invention is the provision of a power operated winch, specifically designed for use in connection with the hoisting and lowering of well drilling and operating apparatus.

An important object of the invention is the provision of a winch mechanism, compactly arranged for use upon an automotive vehicle, from which the same derives its driving power.

A further object of the invention is the provision of an improved winch mechanism including a driven shaft, and a novel driving connection, whereby the shaft may be driven in forward or reverse directions.

A further object of the invention is the provision of an effective winch mechanism compactly arranged to facilitate the operation thereof, and including a novel arrangement of elements whereby the same may be operated in the most effective manner for hoisting or lowering purposes.

ther objects and advantages of this invention will be apparent during the course of the following detailed description.

In the accompanying drawings, forming a part of this specification, and wherein similar reference characters designate corresponding parts throughout the several views,

Figure 1 is a plan view of an automotive vehicle, having the improved power driven winch mechanism mounted thereon.

Figure 2 is a fragmentary elevation, partly in section, showing details of the improved winch, taken on the line 2-2 of Figure 3.

Figure 3 is a transverse cross sectional view, through the driving mechanism of the winch, taken on the line 33 of Figure 2.

Figure 4 is a side elevation of the improved mechanism.

Figure 5 is a fragmentary elevation of certain of the winch mechanism details.

in the drawings, wherein for the purpose of illustration is shown the preferred em- 1923. Serial No. 641,194.

bodiment of this invention, the letter A designates a motor vehicle of any improved type, upon which the improved winch mechanism B is to be mounted. The mechanism B preferably comprises a frame C; winding mechanism D; driving connection E for the mechanism D; and brake device F.

i The motor vehicle A preferably includes the chassis frame 15, and the drive shaft 16, which is operated from the internal combustion engine 17.

In order that the differential mechanism 18 may be disconnected from the drive shaft 16 during operation of the winch B, it is preferred that the drive shaft provided with a clamping collar 19, whereby that portion 20 of the drive shaft 16, which connects to the differential mechanism 18 may be disconnected and lowered, substantially as is illustrated in Figure 1 of the drawings, so that the winch mechanism B may be directly operated from that portion of the drive shaft 16 which is directly conneeted to the internal combustion engine 17. It is preferred that the drive shaft 16 have a sprocket wheel 22 keyed thereon intermediate the clamping or joint connection member 19 and internal combustion engine 17 for cooperation with the winch driving connection, in a manner to be subsequently described.

It is preferred that the winch supporting frame C comprise a pair of spaced 1

beams

23 and 2 1, which are transversely disposed upon the chassis frame 15. A triangular shaped bearing support 25 is connected, as by bolts 26, to an end of each of the I

beams

23 and 24, so that said I beams are held in determined spaced relation at an end of each. A housing 27 which is provided for receiving certain mechanism of the driving connection in a manner to be subsequently described, is provided for connecting the opposite ends of the

beams

23 and 24 as by bolts 28. If desired, cross pieces 30 may be provided upon the

beams

23 and 24, intermediate the bearing 25 and housing 27.

Referring to the winding mechanism D, the same includes a driven shaft 35, which bears at one end in the bearing support 25, and at its other end in the housing 27, so that an end 36 of said shaft extends into the chamber 37 of the housing 27. A cap 38 is, of course, provided upon the support 25 and cooperates therewith to rotatably support the shaft 35. It is preferred that an end 39 of the shaft extend outwardly from the bearing support 25 and be provided with a pulley 40. A winding drum 42 is slidably and rotatably mounted upon the driven shaft 35, and adapted for receiving the flexible cable 43 thereon, in the ordinary manner. The winding drum 42 includes the

circumferential side flanges

44 and 45, which are provided as guides for retaining the cable 43 in position. A collar member 46 is mounted upon the shaft 35 intermediate the housing 27 and the winding drum 42. A flange 49 is preferably provided in circumferential manner upon the. fixed collar 46 which cooperates adjacent the flange of the drum 42. A disc 50 of fiber, or other friction clutching material is provided intermediate the drum flange 45, and collar flange 49, which is provided for coacting with the facing surfaces of said flanges in a manner to be subsequently described. A second collar 52 is provided upon the shaft 35, however, being longitudinally slidable thereon. This collar 52 is provided with key ways 53 interiorly thereof, adapted to slidably receive the keys 54, which are affixed as by countersunk screws 55 circumferentially of the shaft 35. The sliding collar 52 is provided with a flange 56, which is positioned adjacent the drum flange 44, a disc 58 of fiber or like material being provided intermediate the

flanges

44 and 56 for cooperating therewith. A clutch operating device 59 is preferably provided intermediate the sliding collar 52 and the bearing 25, the same functioning to force the sliding collar 52 and winding drum 42 longitudinally of the shaft, and whereby the winding drum 42 may be fixed for rotation with the shaft 35, through the

fiber discs

50 and 58. This clutch device 59 pref erablv includes a movable portion 60 which is rotatably disposed upon the shaft 35, intermediate the collar 52 and bearing 25; this portion 60 being also slidable longitudinally of the shaft 35. A fixed portion 61 is provided, as a part of the clutch device 59, being bolted, as at 63, to the top portion of the bearing support 25. The abutting surfaces of the fixed and movable portions 61 and 60 respectively of the clutch device 59 are spiralled, whereby when an operator grasps the handle portion 66, which is keyed to the movable part 60, and oscillates the part 60, said abutting surfaces will be in such relation as to permit the longitudinal sliding of the part 60 upon the shaft 35, as can be readily understood. It is preferred that the spiral surfaces be broken upon the clutch parts 60 and 61, so that certain abrupt shoulders are provided upon each of said parts, whereby the force of the rotating shaft 35 upon the moving parts 60 may be checked, should said part 60 become stuck, as to tend to oscillate the same by rotation of the shaft 35. A suitable oil cup 67 may be provided ing collar 52; said thrust bearing 70 having a plurality of rollers or any other fric-- tion members 71 therein for cooperation against the facing surfaces of the clutch part 60 and the sliding collar 52. It is obvious that as an operator rotates the clutch part 60 upon the shaft 35, the thrust hearing 70 will force the collar 52 longitudinally of the drive shaft 35, so that the drum 42 will be securely connected by means of the fixed collar 46 and the splined collar 52 to the shaft 35 for rotation therewith.

The driving connection E is provided for connection of the driven shaft 35 to the vehicle drive shaft, including an improved arrangement for selective driving of the shaft 35. The housing 27 is of two part construction, including that part 75 in which the driven shaft 35 bears, and the outside shell 76; the

portions

75 and 76 being connected by bolts 77 thereabout to provide the enclosed chamber 37. A gasket 78 may be clamped intermediate the abutting edges of the housing portions 7 5 and 76 if desired, to make the chamber 37 leakproof, since it is preferred that that portion of the driving connection E which is mounted within the chamber 37 be driven in a lubricant. The connecting arrangement E preferably includes a relatively large bevelled gear 80, which is keyed to the portion 36 of the driven shaft 35, which extends into the chamber 37. A shaft 31 is provided within the chamber 37, being supported as by bearings 82 therein, substantially at right angles to the driven shaft 35, and extending transversely of the enlarged bevelled gear 60.

Bevelled pinions

83 and 84 are provided, freely rotatable upon the shaft 81 and in engagement with the teeth of the enlarged gear at diametrically opposed points. The

pinions

83 and 84 are respectively provided with

jaws

85 and 86 rigid therewith, adapted for cooperation with the jaw ends 87 and 88 respectively of a sleeve 89, waich is splined upon the shaft 81. A groove 90 is provided intermediate the ends of the sleeve 39, which receive a fork 91, slidable therein, a rod 92 being provided for supporting the fork 91 and extending through a suitable opening 93 in the housing 27. In this manner, by reciprocation of the rod 92, the sleeve 89 may be placed in selective engagement with the jaw portion of either of the

pinions

83 and 84, for connection of that pinion to the shaft 81 so that the same may rotate the enlarged gear 80 in either direction, as can readily be understood.

A counter-shaft 95 is disposed within the chamber 87, upon the bearings 96, so that the same is in parallel relation to the shaft 81.

Sprocket wheels

97 and 98 are res acctively provided upon the shaft 81 and the counter shaft 95, which receive a silent drive chain 98, so that rotation may be imparted to the shaft 81 through the counter shaft 95. It is preferred that the counter shaft 95 extend through a leak proof packing 100 exteriorly of the housing 27., a sprocket wheel 101 being provided upon the exterior portion of the counter shaft 95. It is to be noted that the shafts 81 and 95 ertend in substantially parallel alignment with respect to the power drive shaft 16. The sprocket 101 is disposed in the same plane with the sprocket wheel 22 of the drive shaft 10, so that a link chain 108 may be disposed over the sprocket wheels 22 and 101, for driving of the counter shaft 95 from the power shaft 16 of the vehicle A.

In order that the mechanism within the housing 27 may be conveniently controlled, it is preferred that a shaft 105 extend transversely of the winch 13, having a bearing 106 provided for one end thereof adjacent the housing 27, and a standard 107 is provided as a bearing for the other end of said shaft 105. A fork 108 is preferably provided upon the end of the shaft 105 which is disposed adjacent the housing 2'? to cooperate in a grooved collar 109 formed upon the end of the rod 92 which extends exteriorly of the housing 27. A quadrant 110 is preferably provided upon the standard 10? which cooperates with a dog mechanism 111 carried by the hand lever 112 which is keyed to the shaft 105 adjacent the standard 107. It is preferred that the quadrant 110 be pro vided with three notches 11 1 into which the dog mechanism 111 operates, so that the operator by oscillation of the hand lever 112 may so dispose the sleeve 89 within the chamber 87 of casing 27, that the same may be disposed in neutral position; whereby the pinions 83 and 8 1 will idle upon the shaft 81, so that the driven shaft 35 will not be rotated; for rotating the pinion 83 whereby the shaft n'iay be rotated in one direction; or for feeding the pinion 8 1 into engagement with the shaft 81 and whereby the shaft may be driven in an opposite direction. Thus, the winch driven shaft 85 may be held in non-rotatable relation or driven in forward or reverse directions for effectively controlling the cable as which is wound thereon.

Referring to the brake device F, the same includes

brake drums

115 and 110 which are riveted or otherwise secured to the outer surfaces of the winding drum flanges 4/1 and 45 respectively, and extending circumferentially about the

fiber discs

50 and 58 and the flanges 19 and 56. Flexible bands 11'? and 118 are respectively provided for the

drum flanges

115 and 116, in order to effect a braking action upon the drum 12. ()ne end of each of the brake bands 117 and 118 is fixedly connected, as at 120, to the supporting frame C. The means 120 which secures this end of the brake band may be provided in the cross braces 80. The opposite ends 122 of the brake bands 117 and 118 are connected to the crank portions 123 and 121 respectively of a crank shaft 125. The crank shaft 125 extends transversely of the winch B and bears at one end in the standard 25 and at another end in an. individual. bearing 127. The shaft 125 is a two part shaft, and has the

ends

128 and 129 bent intermediate the ends of the shaft to support an equalizing member 130 upon their ends. in order that the crank shaft 125 may be conveniently operated, a hand lever 181 is oscillatively connected, as at 182, to the frame C adjacent the standards 107. The lower end of this hand operated lever 131 is keyed to a shaft 184:, which extends transversely of the winch B and is provided with an arm 185, extending outwardly therefrom intermediate its ends upon which a rod 136 is pivotally connected. at its free end. The opposite end of this rod 136 is connected to the equalizer 130. Thus, it can readily be seen that upon oscillation of the lever 131, the crank shaft 125 will be oscillated for tightening or loosening the brake bands 117 and 118 upon the brake drums of the winding drum -12, so that the winding drum 42 may be either retarded or permitted to rotate freely. dog'or pawl 1 10 is pivoted upon the hand lever 131 adapted for cooperation with the toothed quadrant 1&1, whereby the brake bands 11?' and 118 may be retained in a tightened position for holding the drum 42 in a set position if desired.

From the foregoing it can be seen that a winch mechanism has been provided, which is practically constructed, and may be easily controlled by an operator for effecting the feeding or winding of the cable 13 with respect to the drum 42, so that an operation may be performed. The mechanism E may of course, be used to control the direction of rotation of the driven shaft 35. The clutch mechanism 59 has been provided, so that the winding drum 412 may quickly respond to the position in which the operator throws the movable part 00 thereof. Due to the arrangement of the winding mecha nism 1), there is no liability of slipping or lost motion in the handling of the cable 4:8. The brake device F, of course, serves the operator in holding the drum B in a desired position, and is a very durable construction which is capable of easy operation. In order to facilitate operation of the crank shaft 125, a pedal 145 may be pivotally connected as at 146 to the chassis frame 15 of the vehicle A, and a connecting rod 147 connected in pivotal manner intermediate the ends of the lever or pedal 145; the opposite end of this rod 1&7 being pivotally connected as at 1&8 to the free end of a crank portion 14:9 upon the shaft 125.

Various changes in the shape, size, and arrangement of parts may be made to the,

form of invention herein shown and de scribed, without departing from the spin of the invention or the scope of the claim.

I claim:

In a structure of the character described, a driven shaft, a housing for receiving an end of said shaft and formed of separably connected inner and outer side sections, a relatively large gear keyed on the portion of said shaft extending within said housing, a second shaft disposed at right angles with respect to said first mentioned shaft, bearings for the second shaft Within the housing and secured to the inner side section of said housing, pinions rotatably mounted on said second mentioned shaft in engagement With said relatively large gear at diametrically opposed points, a sleeve splined upon sa d second mentioned shaft intermediate said pinions, clutch means on the ends of said sleeve and upon said pinions, means extendv ing into said housing between the sections thereof and having its inner end portion provided with means for engaging said sleeve for selective' sliding of said sleeve 1 on said second shaft whereby said pinious be selectively keyed to the second shaft,
