To all whom it may concern:

Be it known that'I, GEORGE W. KING, a citizen of the United States, residing'r at Marion, in the county of Marion and State of Ohio, have invented certain new and useful of which the folbeing had therein to the accompanying drawings.

`This inventionrelates to v winches,

Improvements in Winches,

and

chinery or winch mechanism employed for the purpose of independently controlling the winding in and paying out of a number` of ropes by-means of a corresponding lurality of drums driven from a single shat, either wholly or in part, by a common train of gearing, the entire mechanism being mounted in a single frame, so as to constitute a complete organized machine v adapted to be driven from a singlel motor and controlled by a single operator.

The structureis primarily devised for use in connection withgold-mining dredges for the purpose of controlling the head line the four ileeting lines and the two Spud-controlling lines, by means .of which the position of the dredge is shifted and maintained, although the structure is obviously capable ofother applications. e

The obj ect of my invention is to provide a simple, compact, andself-contained structure designed with a special view to the reducing of the amount -of power required to actuate the same.

To these and other ends myinvention consists certain novel features which I will now proceed to describe and `will then particularly point out in the claims.

. In the accompanying' drawings,lFigure 1 is a plan view, partly in section,of a winch .mechanism embodying my invention in one form. Fig.. 2 is a side elevation of the same, partly in section; and Fig. 3 is anenlarged transverse sectional view taken on the line the arrows. Y

In the said drawings I have shown the ,main frame of the 'structure as substantially, being composedI of lon-` gitudinal side members 1 and transverse end members 2. The former are preferably composed of channel-bars 3, placed back to back or with their channelsarranged out- ,ward, the* beams being spaced apart at the under and -support more particularly to that class of winch mam x of Fig. 1 and looking inthe direction of,

bottom by spacing-blocks 4, T-shaped in cross-section, which also serve to support the frame,'one of the members of said T-shaped blocks (indicated by the reference-numeral 5) extendingupbetween the channels to s ace them apart, while the two other mem ers (indicated b y the reference-numeral 6)extend the channels from below.

At their upper edges spaced a art by 7, forme on the bases 8 'of the several shaftsupporting'brackets .9, which are mounted on the to side mem ers of bers 2 are preferably bars, having 'their channels directed; outwardly and secured to the side members by means of angle-.bars4 10. Upon this frame, near one end thereof, there are mounted on opposite sides thereof two upwardl -extending ,brackets'11, carrying bearingoxes 12, in which is mounted the main driving-shaft 13 of the winch. Said shaft is provided with a wheel or pulley 14, by means of which the shaft 13 is driven from anyz suitable motor.` Said shaft 13 has small pinion 15 and,large one of which may because the frame. ,The end mem- 'of the channels constitutingthe',I

OHIO, AssIGNOR To THE MAEioN STEAM these channel-bars are downwardly-extending ribs with the shaft by -theengagement therewith i of a clutch 17, s lined on the shaft 13, so as to rotate therewith and capable of sliding longitudinally on said shaft, vs o 'as to be brought into'engagement with either of said pinions.

18 indicates a counter-shaft located belowy driving-shaft 13, being mounted in bearing-boxes 19 on the slde' and parallelv with the members. of the main frame. This countershaft is provided with a large gear 20, secured thereon and meshing with the small pinion 15, and a s all gear21, also secured on said counter-sh ft and meshing with the largeA pinion 16.y By reason of .this construction" the counter-shaft s eed and power may be variedrelatively to t e speed and power of the .driving-shaft, so as' to glve greater speed when light loads'are handled and greater power when heavy ing the speed ofthe motor. The countershaft 18 has centrally secured thereon a pinion 22, from which a plurality of windingdrums are driven through a single train of gearing, which I will st noting that the end ofthe counter-shaft on that side of themachine opposite the side loads are handled without vary- IOO' - 1 o 5 now proceed to describe,

on which the driving Wheel or pulley 14 is located is extended to receive a spool or drum 23, which may be used as an ordinary winch or windl-ass by taking around it a, turn or two of any rope which it is desired to manipulate.

In the present instance I have shown six drums as driven from the inion 22, although this number may bevarie These drums are arranged in pairs, two drums upon a common shaftI so that, in the present instance there are three of these shafts, (indicated bythe reference-numeral 24.) The structural features of each shaft and its two drums being similar to those of the others, I ,will confine my description to one set. yEach shaft 24 is a fixed or non-rotating shaft mounted in supporting brackets or housings 9, hereinbefore referred to, located on top of the side frame members 2. The shaft is-secured in these supports in any suitable way*- as, for instance, by means of a pin 25 through each end of the shaft and through the cor-responding housing. Each shaft is provided with a central collar 26, which serves to maintain in position a gear-wheel 27, which is loosely mounted on said shaft, so as to rotate freely thereon, being prevented from ,moving longitudinally of the shaft by the collar 26. To this end each gear-wheel 27 is composed of an annular peripheral portion 28, detachably secured between two centers 29 on the shaft 24 or on opposite sides of the collar 26. The centers 29 are provided on their opposing inner faces with seats 30 to receive the annular gear 28, which is secured in said seats by bolts 31, so as to be capable of'being detached from the centers. These latter are provided with bushings 32, of suitable antifriction material, which bear not only against the body of the shaft 24, but. also against the sides of the collar 26, to take up thelateral thrust arising from the engagement of the friction-cones hereinafter described. As these bushings and the collar are subject to wear, provision is made for bringing the centers closer together after such wear occurs by the insertion between the lateral faces of the members 28 and 29 of spacing pieces or liners33. By the removal of these spacing pieces or liners the centers may be brought closer together and any wear which has occurred may be readily taken up.

Each gear-wheel 27 is provided on its opposite sides with conical friction surfaces or rings 34, these. being preferably formed on the peripheral portions of thecenters 29, as shown. On each shaft 24 there is mounted on e'ach side of the central gear 27 thereof a winding-drum 35, said drums beingloosely mounted on said shaft. Each drum isprovided with a conical friction surface or ring 36, adapted to coperate with the corres onding frictional surface 34 of the gear 27.

achy drum is moved into engagement with the central gear, so as to be rotated thereby by means of a cam-shifting collar 37, mounted loosely on the shaft 24 between the outer end of the drum and a similar fixed cam-collar 38 which latter issecured in positionon the shaft by having an arm or lug 39 thereof extended upward and secured to acorrespondbe so rotated on the shaft 24 that its inclined cam-surface, bearing against the similar but reverse cam-surface of the coperating camsurface of the fixed collar 38, ywill move the drum longitudinally on 1thev shaft 24 and cause its friction-cone 36 to engage with the corresponding friction-cone 34 of the gear 27 with any desired pressure. A washer or wearing-ring 42 is interposed between the shifting cam 37 and the end of the drum 35. The limits of vmovements of the drumfor yany given movement of the shifting collar may be regulated by the adjustment around the shaft 24 of the fixed collar 38, and to this end the lug '40 is provided with a plurality of apertures 43, arranged in the arc of a circle having the center of the shaft 24 for its center. A bolt 44, which connects the lug 39 to the lug 40, may be passed through any one of these apertures, according tothe angular adjustment around 1the shaft 24 of the fixed collar 38.

Provision is made for disengaging the friction-cones and holding each drum against its y shifting collar, the means for the accomplishing of this consisting of spring-actuated plungers 45, bearing against the face of the gear 27, each center of which is provided with an annular bearingsurface46coperating with the plungers 45. Each plunger 45 is mounted to slide in a housing 47, carried by the head 48 of the drum 35, and-is backed by Aa spring 49,-

plunger and against an adjusting-screw 50, threaded into the outer end of the housing and serving as an abutment for the spring and as a means for adjusting its pressure. The inner head 48 of each drum is provided with alperipheral flange 51, the inner surface of whichforms the conical frictional surface 36, Vwhile its outer surface 52 is cylindrical and receives a brake-band 53, which encircles the same and which is controlled by a shaft 54, having an operatingfarm 55. The main frame. is provided with cross braces or members 56, preferably in Kthe form of channelbars, on which the bearings of the brake.-

shafts 54 of two of the pairs of drums are mounted, the third brake-shaft being mounted on the end member 2 adjacent to its pair of drums.

Provision is also made for lubricating the bearings of the drums 35 on the shaft 24 by means of an oil-channel 57, extending-in-v IOO located in said housing and bearing against the'irmer end of the IIO cant. When the apparatus is in use, thedrivingward from each end. of the shaft and thence outward to theperipherythereef, where itterminates in communication with an oilspace 58, formed in the inner central portion of the body of the drum. An oil-cup or lu-` bricator 59 is located at 'each .end of the shaft to supply. each channel 57 with lubrishaft 13' is lin constant rotation, and the counter-shaft'driven at either of its two speeds similarly rotates the pinion 2,2, which meshes with the first of the series of gears 27,

the Asuccessive gears 27 being in mesh with Aeach other,so that all of'said gears are vcontinuous rotation. Any one or more of the drums may be rotated to wind the cable thereon by bringing it into frictional connecl tion'with its coperating gear 27 through the mechanism provided for that purpose.. Similarly any one or more of the drums may be disconnected from its' .driving gear and either held stationary by its band-brake or be permitted to turn under the load tonnwind the rope or cable.

y In mechanisms of this kind as heretofore constructed, so far as I am aware, it has been customary to secure the driving, membecorresponding to the gear 27 to the supporting-shaft corresponding tothe shaft 24, thur making the shaftia rotating shaft and creats ing friction between said shaft and the Winding-drums when thesef latter are vheldv stationary.

` strong pull on its rope, the amount of friction relatively smaller capacity.

between said drum and the lshaft rotating 4therein is necessarily large, increasing lthe load on the motor, and where a number or all of the drums are thus held stationary under load it will .be seen that the loadon the vmotor even when doing no useful Workis very-greatly multiplied. vAll .of this useless frictional resistance is obviated b'y the construction whichI have devised,.in which the Asupporting-'shafts are stationary or non-rotating, both driving-gear and drums being free to rotate on said shaft independently of each other, so that when the drums are disconnected from the 'driving-gear and held stationary under load said load has no effect whatever in: increasing the frictional'resistance which the motor has to meet.

I am therefore enabled to obtain a maximum of efficiency from a motor of givencapacity or to ob'taln a greater eiiiciency from a motor Vof Win hes of this character usually constructed also. include in their structure a' winding-drum used for'the .head-line in the .case of a dredge anddriven independently of the wind' -drumsheretofore considered. Such a head-line drum is shownin the present instance, being indicated by the referencenumeral 60. It is mounted to rotate on a 66, also mounted lo 1 a friction-drive. v

Said drum has a band wheel '62, surrounded by a brake-band 63 and controlledy from a shaft 64, provided with a controlling.- arm.65. By this means the drum may-be held lstationary under load or permitted to unwind its rope or cable. The drum is positively driven from a gear-wheel osely on the shaft 61 yand meshing with a pinion l67 on the countervshaft 18. Said gear-wheel may be connected to and disconnected from the drum in any suitable manner, preferably by means of lThe specific lform of drive nulus 68 on the drum isJsurrounded Yby a lbrake-band 69, one end of which is Xedly connected tothe gear 66. VThe other end is connectedto an eccentric-pin 7 0 on-a shaft 71 mounted in the gear-wheel 66l and connected by an arm 72 and link 73 with a collar 74, mounted looselyon the hub of the gear- Wheel 66. This collar has secured to it a band-wheel 7 5, around lwhich passes a brakeband 76, controlled by a shaft 77 and operat` ing-arm 78.` Stoppage or retardingof the wheel --7 5 byits brake-band will cause the collar l74; to actuate the'shaft 71, so as tol tighten the brake-band 69V on the band-Wheel 68 of the drum 60, and thereby cause this latter to rotate. .This construction of-.the

head-line drum' possesses they advanta e already pointed out in connection wit the other winding-drums, that 1t releases the continuously-rotating parts of the .friction ofl the load on the drum, since the shaft on which the drum is mounted is stationary.

I tvwill beobserved' that the structure is balanced, the drums being readily accessible and suitable provision vbeing made for wear and adjustment.

-I do not wi h, however, to-be understood .as limiting my invention as toits broader devices to' a correspllliding group 'of hand-- convenient reach of` levers arranged wit the operator.
