Application filed February '14, 1922." Serial No. 536,435.

Z "o'aZ Z lb/1072?, it may concern: I Be it "known that LBENLIAMIN F. WEBB, a 'citizenjof the United States, residing at ,Sistersville, in the county of Tyler and Estate of est Virginia, have invented cer- 'tain new and useful Improvements in Finches, of Whichthe following is a speci- 'fi'cation.

This invention relates to hoisting and- Winding mechanisms generally, and more particularly to a power :driven reeling and .windingdrunrtype of winch capable of being positively operated "in both directions of its rdtative "movements 1 The principal object of the invention is to provide for a mechanism ofthecla-s'smem" tioned, and :one involving'the use of planetary 7 gear trains arranged to be alternately used "for driving the hoisting or'winding drum in its rev'ersed directions of rotation Without necessitating'the'reversal'ol the di rection er rotation of the driving or power slia'ft, or t'hestopping'and starting up ofthe I power agent applied to'the latter for-its op- 25':eratioi1.

Another object of the 'inventiontisito provide for a 'niechanisin"ashereinbefore char- "ater ized, :and one of an extremely siinple 'and durable construction and "arrangement 30 'of parts, giving "maximum -eflioiency in "operation, and altordin'g great ease "in control. *With the foregoing and other objects in 'view, the 'invention 'resides 'in the certain new' and useful construction, arrangements 35-and"operati0n of. parts, "as will be herein-- aftermore fully describeth'set Iforthin the appended claims, andi'llustrated 'in the ac- 'cornp'anying drawings,"inwhich a "Figure -1 isa verticalilongitudinal section 40.through a preferred embodiment of the winch ihechanism,

Fig. 6 is a vertical transverse section taken on the line 6-6 of-Fig. 1-,lillustrating the second planetary gear train forefi'ectingfthe rotation of the hoisting or windingdru'm in a direction reversed to that of :the other planetary gear train and the power or driving shaft.

Referring to the drawings, wherein simila! characters'of referencewdesignate corresponding parts throughout'the several views 'thereofltthe-numeral 10 indicates a power or driven shaft suitably johrrialed at its opposite ends in standards '11 and -12"rising"from rotation on the shaft 10, 'isa hoisting or winding drum or winch consisting of a pair fof spaced circular plates 14 and "15, having their opposed "faces formedfto prov'ide cylindrical hub portions '16, over which are fittedjthe opposite ends of "a cylindrical -"sleeve'17, the engaged .ends of the latter 'be- Mounted for free ing secured to the hub portions 16,. by ineans I of machine screws or the like :18, subs-tan tiallyas 'is shown inFigs; 1 and '3.

Secured to the outer face ofthe drum platel l, by means of bolts or thevlike -ltl, is 'anannular ring orintern'al" gear 20, which is "flush with the edge of the plate 14 and meshes with the outer gears or pinions '21 and 22,0fa planetary gear train whichfurther includes an intermediate pairof oppositely arranged gears-23 and-24c, inmesh with the outer gears QJl-and 22,- and also 'Ineshingi with a central gear or pinion 25 keyecL'as at'26,' directly onthe powe'nor drivingrsha'ft 10. The gears or pinions'ill, 22, 23, '24 and "25'are'disposed-inline diametrically of and between an inner disk or plate '27 an'dan Outergear plate QS, and the gears orpinions 21, 2252 3 and QAare loosely jouri'ialedon stub 'shafts-29,'the latter being in the form of bolts or the like age-ting to secure the'plates 27 and 28Ytogether-forjrotation one with the other.

portion 57, arranged hand lever 58, pivotally mounted on the bracket 34 support-ed in position on the base or bed plate 13, and the other of its ends attached to an angularly disposed portion 35, formed at the inner end of a hand lever 36, pivotally mounted on the pivot pin aforesaid. Similarly, a brake band 37 is trained around the outer periphery of the internal gear 20, and has one of its ends made fast to a pivot pin 38, carried in a bracket 39, which is supported in'proper position on the base or bed plate 13, while its other end is secured to an angularly disposed portion 40, arranged at the inner end of a hand lever 41 pivotally mounted on the pivot pin 38. be here noted that the gear plate 27 and the planetary gears 21, 22, 23, 24 and 25 are housed within the confines of the internal gear 20, and the circular end plate 14 of the drum and that the open side of the internal gear 20 may be closed in a known manner to admit of the .inclosed space being filled with oil for the thorough lubrication of the said planetary gears.

The circular plate 15, at the opposite end of the hoisting or winding drum, has secured on its outer face at the peripheral edge thereof, by means of bolts or the like 42, an annular ring in the form of an internal gear 43, with which meshes a pair of-oppositely disposed planetary gears 44 and 45, which are driven from a spur gear or pinion 46 keyed, as at 47, on the power The planet gears 44 and 45 are loosely journaled on stub shafts or spindles 48, preferably in the form of bolts passed through inner and outer circular gear plates 49, and 50, which are loosely journaled on the power or driven shaft 10. The planetary gears 44, 45 and 46, together with the inner gear plate 49, are housed. within the internal ar 43, and

the outer open side of the latter may be closed in the usual or known manner, so that the space enclosed thereby may be filled with oil for the thorough and continupgs e inner and outer gear plates 49 and 50, are preferably spaced apart by means of spacing sleeves -51,through which are passed suitable fastenings or bolts 52. The outer gear plate 50, has formed on its outer face, and flush with the peripheral edge thereof an annular flanged portion 53, around which is trained a brake band 54, having one of its ends connected to a pivot pin 55, carried in a bracket 56, supported on the base or bed plate 13. The other end of this brake band 54, is secured to an angularly disposed at the inner end of a pivot pin 55.3

In the operation of the mechanism as thus constructed and arrangedyarrd with power applied to the drivingshaft 10 by a sprocket 59, and

all brake bands 33, 37 and 54 in normally inoperative position, the power shaft will run idle without effecting either of the planetary gear trains or the rotation of the drum or winch. By now manipulating the hand lever 36 in a manner to tighten the brake band 33, on the gear plateflange 32, the latter together with the planet gears 21, 22, 23 and 24, will be held against bodily rotation, so that the gear 25 will drive the intermediate planet gears 23 and 24 in a direction reversed in its own rotation, or to the direction of rotation of the power shaft 10, while these latter gears 23 and 24 will, in turn, drive the outer planet gears 21 and 22, and consequently the internal gear 20 and the drum or winch in the same direction as that of the gear 25, and the power or driving shaft 10. This forward rotation of the drum or winch. may behalted when desired by the loosening up of the brake band 33, and, if desired, the mo mentum of the same be checked by the manipulation of the hand lever 41, for the application of the brake band 37, on the out-er periphery of the internal gear 20 To reverse the direction of rotation of the drum or winch, and with both of the brake bands 33 and 37 in normally inoperative position, the hand lever 58 is manipulated to tighten the brake 54 on the flanged portion 53, of the gear plate 50, when the latter, together with the gear plate 49 and the planetgears 44 and 45, will be held against bodily rotation, so that the gears 44 and 45 will be driven by the gear 46, and in a reversed direction with respect power shaft 10, and, in turn, the internal gear 43, together with the drum or winch, will be driven by the gears 44 and 45 in the same direction of rotation thereof, and reversed with respect to the gear 46 and the power shaft 10. This reversed direction of operation of the drum or winch may be halted by the loosening up of the brake band 54, and its momentum stopped by the subsequent manipulation of the hand lever 41 to again tighten the brake band 37 of 1. In a mechanism as characterized, a,

driving shaft, a winding drum loosely mounted on said driving shaft, a planetary gearing interposed between said driving shaft and one end of said drum for thereto and to the effecting the rotation of the latter correspondingly With the rotation of the shaft, and a second planetary gearing interposed between said driving shaft and the other end of said drum for effecting the rotation of the latter in a direction reversed to the direction of rotation of the shaft.

2. In a mechanism as characterized, a driving shaft, a Winding drum loosely mounted on said driving shaft, a planetary gearing carried on said driving shaft and cooperative With one end of said drum for rotating the same correspondingly With the direction of rotation of said shaft, a second planetary gearing carried on said shaft and cooperative with the other end of said drum for rotating the same in a direction reversed with respect to said shaft, and means cooperative with said planetary gearings whereby to render the same operable one independently of the other.

3. In a mechanism as characterized, a driving shaft, a Winding drum loosely mounted on said driving shaft, a planetary gearing carried on said driving shaft and cooperative With one end of said drum for rotating the same correspondingly with the direction of rotation of said shaft, a second planetary gearing carried on saidshaft and cooperative with the other end of said drum for rotating the same in a direction reversed rotating the same correspondingly with the direction of rotation of said shaft, a second planetary gearing carried on said shaft and cooperative With the other end of said drum for rotating the same in a direction reversed with respect to said shaft, independent means for controlling the operation of said planetary gearings, and means for effecting a braking action on said drum When said planetary gearings hav'e'been rendered inoperative. f

In testimony whereof, I aflix my signature hereto.
