i 1 of differentialmechanism preferably in the a i tress.

form of planetary gearing by means of which a powerful pull can be exerted upon a flexiblemember such as a rope of wire, hemp or othermaterial, which is secured to,

and adapted-to be wound upon the drum of the winch when the frame of the apparatus is suitably anchored and the winding mechanism actuated.

An apparatus of this character is particularly desirable under many circumstances, for example I it is frequently desirable to carry a portable winch of this character in an automobile so'that it may be readily used to pull the machine out of a position of dis- Another instance is as a support for a scaifold on platform' such as used by painters, in which the winch maybe used to raise and lower the platform along the side of the building. I

Such winches may also be employed advantageously in anyindustry where it is necessary to raise and lower or moveheavy obects by hand power, and particularly where a'compact apparatus having a long reach or scope is desired.

The preferredrembodlments of the inven tion disclosed hereincomprise a frame havmgja rotary drivenmeinber, preferably a drum rotatably mountedtherein upon which a coil of lrope wire, or other 'flexible material-may bereeled, the drum being rotated preferably by means of a train of planetary differential gearing which may beactuated by a crank, ratchet lever or other means.

()ne of-the objects'of the'invention is to provide'ran apparatus of the character above described which is capable of transforming thepower applied to a hand operated crank,

or the like, into'a powerful pull upon the rope, so that by a relatively small exertion PO TABLE WINCH.-

the operator may displace, or lift, a very heavy weight. a i i i i {A other object of the invention is to provlde an apparatus of the character described which may operate under diiferent speeds of revolution of its crank so as to give either a slow and very powerful pull upon the rope, as above indicated, or a more rapid pulling motion thereupon with correspondingly less power according to the position in which the actuating crank is attached to the drum operating mechanism.

Another object of the invention is to provide, in an apparatus of the characterreferred to, iueans for releasing the drum from its actuating mechanism in such a manner that the drum may be permitted to rotate freely for the purpose of reeling off the rope rapidly; or in which the rope may be wound upon the drum by power applied directly to the rim thereof, while the usual drum actuating mechanism remains stationary.

Other objects of the invention will more fully appear from the following description and the accompanying drawings and will be particularly pointed out in the annexed claims.

The drawings illustrate certain preferred embodiments of the invention, but it will be readily understood that the invention may be embodied in other forms within the mean ing and scope of the subjoined claims.

maintaining the gears in the most efficient contact.

The actuator at its ends may be provided with rings 3839 which may be integral 5 with the actuator or may be made separately therefrom and shrunk thereupon,

these rings being adapted to engage similar rings on the series of planetary gears which revolve around the central actuator. As

illustrated in Figs. 1 to 6 ofthe drawing the actuator is provided with eight teeth at each end spaced apart in such a mamier as to leave an annular space 40 therebetween in which the central gears of the traveling or planetary gears may pass without interference. The planetary gears desirably are of a composite character of the form illus trated in Fig. 6 and may comprise three gears rigidly secured together upon a central shaft or preferably cast integral throughout, the outer gears 41-42 each having the same number of gear teeth and the intermediate gear 43 a different number of teeth and a different pitch. These members may, as stated, be cast integral in theform of a hollow toothed cylinder, a suitable bear-' ing hub 44 being secured in the end of the cylinder and provided withafcylindrical axis 45 seated in the circular apertures 29 of the crank plate 28. The hub 44 and the cylindrical axis 45 desirably are made to fit loosely but non-rotatably within the hollow toothed cylinder to permitthe planetary gears to float freely and thus automatically '85 to adjust themselves in such a manner that each takes its proportionate share of the stress.

By spacing apart the members of the planetary gears which engage fixed annular 40 gears upon oppositesides of the casing and by placingthe gear which engages the annular gear of the drum between them the stress imposed upon the mechanismbecomes balanced and the tendency to end-crawl is 4 eliminated.

The ends of the lanetary gears desirably are provided with bearing rings "4647 Which may engage the corresponding bearing rings 3839 of the actuator, thus pro- 50 viding a rigid construction adapted to with: stand lateral strains especially since the rings-4647 also engage the annular bearing surface 11-12 of the frame] It will :be understoodthat the bearing ringsupon i thecentral actuator and upon the planetary gearssho'uld be of precisely'the pitch diameter of the respective gears inorder to permit proper relative rotation of the gear system, and in order thatv these bearing rings may. take the'pla'ce ofordinary shaft bearings" and become iniefl'ect roller bearings.

The central gear 43 desirably is spaced apart from the gears"41"42 to receive a ring 50 provided with an internal gear 51 adapted to mesh with the central teeth 430f the planetary gears, the ring 50 supporting and being preferably detachably connected to the winding drum 52.

If rotation is imparted to the actuator 20 through the crank 24,the gears upon said actuator which engage the teeth upon the planetary gears will transmit rotary motion to them and since the planetary gears also engage the internally toothed gears 14 of the main frame the rotation of the actuator will cause the planetary gears to travel in a circular path.

It will be obvious that by reason of the fact that the central gear 43 is of a different pitch than the gears 41 and 42 a differential movement will be imparted to the ring 50 and the drum 52.

If the central portion 26 of the crank 2-1- is engaged with the annular projections 27 of the crank plate 28 in which the planetary gears are journaled, power will be applied directly to the planetary system so that a greater speed of rotation will be imparted to the drum, the central actuator or sun wheel 20 revolving idly during such operation.

It will thus be obvious that rotary motion may be transmitted from the crank 10 the drum either through the central sun wheel, to provide for a slow movement of the drum with the transmission of a great amount of power; or may be applied directly to the planetary gears to attain a greater speed of rotation of the drum, with a correspomling decrease in power as may be useful in hauling in the slack rope.

It is desirable that the winding drum shall be rotatable independently of the actuating gearing in order to provide for the rapid unreeling of the rope or wire which is coiled upon the drum, and also to permit the rope to be rapidly reeled up after the device has been used.

Provision is made for the independent rotation of the drum in the device illustrated in Figs. 1 to (3 of the drawing by forming the ring 50 with a series of inclined notches 55 to form ratchet teeth 56 adapted to be engaged by a pawl 57 which may conveniently be carried ina recess 58 in the body of the drum 52, this pawl being secured therein by a cover plate 59 suitably attached to the end of the drum; The pawl may be of the form illustrated in l' 'igsi 3 and 4' which comprises the ratchet engag ing member or pawl 57 having a cylindrical stud seated in a corresponding socket at the end ofthe recess 58 and provided with a laterally extending arm 60 lying within the plane of oneotl'; the outer flanges 62 of the drum. The arm 60 may be maintained in interlocked position as illustrated in Fig,

3 by a dog 63'having a projection (34 at its end engaging the, arm 60, orit may be retained out of engagementzwith the ratchet by a similar dog 65 having anoffset end 66-adapted to engage-the other side ofthe pawl arm 60; f

When the pawl 57 is in engagement with a tooth 56 of the ring:- 5.0 the drum will rotate in unison with the ring, but ifthe pawl. is disengaged from the ring. in the.

manner aforesaid the drum maybe rotatedi freely independently of the gearing, which will. remain stationary;

The. relative .PO SltlOllS ofthe ring. 50 and the drum 52 duringithe free'rotatibn' ofthe heretofore described.

latter may be preserved by providing guid ing. means upon one of the members engage ing a recess in the other. As. illustrated herein, the; means provided comprises an annular groove'67 in the outer periphery of' the ring 50 which is engaged, by a. screw 68 seated in the drum 52 and extending. lnto:

- said annular groove.

The of the actuator is apertured near its end to receive a cylindrical extension 99 extending from ,V the hub 92 of the spider 93. A series of anti-friction rollers 100 desirably surround the extension 99 so that the hub 98 of the actuator will rotate easily thereupon The planetary gears 95 desirably may be mounted uponshafts 101 which arejsupported at their ends respectively in the spider 93 and the circular plate 94, a series of anti-friction rolls 102 being desirably interposed between said shafts and the hubs of the planetary gears 95. The teeth 97 of the planetary gears engage the teeth of an annular rack 103 formed upon a flange 10 i projecting inwardly fromthe side plate 80, the opposite end of the planetary gear being provided with a series of teeth 105 of different pitch which engage an annular series of gear teeth 106 projecting inwardly and preferably integral with the drum 107. The drum 107 may be provided withthe usual flanges 108-109 which may be provided with apertures 110 to reduce the amount of metal and consequently the weight of the device. In order to maintain the drum 107 in properfposition within the frame the drum may be provided centrally with a pair of adjacent ribs 111 and 112 forming therebetween an annular recess 113, and each of the planetary gears may be provided with a projecting rib114l engaging the annular recess 113 so that the drum will be maintained at all times in proper position within the supporting frame. By making these cylindrical surfaces of thepitch diameter 'the anchoring rope may be attached to either one or the other of said yokes- In the operation of the device the yoke 118 will be attached tothe anchoring rope and the rope from the drum 107 will be attached to the object to be moved. Power may then be applied either throughthe hub 98 of the actuator or through the hub 92 of the spider which carries the planetary gears according to whether a heavy object is 'to be moved or a relatively'light one.

"In the former case the rotation of the actuator 98 will cause its integral gear 96 to rotate the planetary gears 95, which by reason of their engagement with s theinter- 11a1 .gear'103.of. the frame wi l se he gages the internal gear 106 of the drum, the

revolution of the planetary ears about the central axis. By reason of t e fact that the gear 95 which engages the gear 103 is of a difl'erent pitch from the gear 105 which endrum will be given a differential rotation relatively to that of the planetary system and great'power will be transmittedfroin the actuator to the drum.

If an object of less weight is to be moved the power may be applied through the hub 92 of the spider 93 which carries the planetary "ears in which case the planetary gears Will be directly rotated by the crank and a greater speed of revolution of the drum attained, the actuator 98 in the meantime rotating idly-upon its axis.

In order to unreel the rope from the drum the locking pawl 116 will be removed from engagement with the ratchet teeth 115 whereupon the rope may be unwound rapidly, in such instance the planetary gears will of course revolve backwardly since there is no means provided in this embodiment of the invention for detachably connecting the drum from the internal gear through which it isdriven by the planetary system.

. In Figs. 9, 10 and 11 I have illustrated a modified form of my invention in which a single planetary member is utilizedto produee the required differential movement of the drum whereby a strong pull upon the rope may be exerted through very small and light mechanism. 1

As illustrated herein the frame preferablv is in the form of two narrow straps 125 -426, the ends of said straps being provided with inwardly extending abutting cylindrical posts 127128 secured together by screws 1 129 or in any other suitable manner. These straps are provided with central apertures 130-131 adapted to receive the hubs of an actuator and a relatively rotatable member which will hereinafter be described. ,The

' straps are so formed as to provide bearings 132133 adapted to. receiveanti-friction rollers 134 135' to provide for the easy rotation of the actuatoruand said rotatable member, One .of the straps126 is provided with an inwardly extending flange 136 provided with teeth 137 forming a rack adapted to be engaged by the planetary member.

The actuator desirably is in the form of a cylinder 138 having. an eccentrically disposed stud 139 mounted in the bearing and provided with an angular extension 140 to receive a suitable actuating-crank.

The stud 139 is provided'with ahollow inner end adapted to receive an extension 125 141 of the hub of a'rotatable member 151 in the form of a disk having an inwardly extending flange 152 provided with teeth 153 adapted to be engaged by the planetary member, the rotatable member 151 being de- 130 tachably eeeiii'eclwtothedrum 154 in a manof the drum during theflre'eling operation I ner hereinafter to be deserihed.
