LOGGING- MACHINE. I

SPECIFICATION forming part of Leaetsraant No. 650,283, dated May 22, 1900.

Application filed July 18, 1899.

To alt whom it may concern:

Be it known that LEDWARD TURKEY, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Ore gon, have invented a new and useful Logging Machine, of which the followingis a specification.

This invention relates to logging-machines, and more particularly to that portion known as the hauling-rig, and it has for its object, first, to provide an arrangement of the rig to adapt it for employment in connection with a single cable, in connection with which is employed a slack-drum, which drum is rotated in a manner that will cause it to take up the slack with speed and efiiciency and at variable speeds corresponding to the speed of the winding-drum, its variation ,in speed being automatic.

An additional object of the invention is to producea clutch mechanism which will act to eifectively hold the drum upon its shaft and in which also the drum will be accurately centered at each operation to rotate concentrically with its shaft and prevent the usual wabbling motion incident to the wearing of the bushings of the drum.

.Further objects of the invention will be noted from the following description.

In the drawings forming a portion of this specification and in which similar numerals of reference designate corresponding parts in the several views, Figure 1 is a side elevation of a hauling-rig equipped with haulingdrums and arranged in accordance with this invention. Fig. 2 is a plan View of Fig. 1. Fig. 3 is a horizontal central section of a hauling-drum with its clutch mechanism.

Referring now to the drawings, the windingdrum and its clutching mechanism employed in this rig consist of a drum-hub 5, which is loosely mounted upon a shaft 6 and has the usual Babbitt or other metallic bushings 7. At one end of the hub 5 is an outwardly-extending radial flange 8, which is itself provided With laterally-extending flanges 9 and 10, projecting away from and parallel with the periphery of the hub 5, and the adjacent faces of which flanges 9 and 10 are tapered inwardly to form an inwardly-tapered annular groove 11, which is adapted to receive at times a similar clutch-ring 12, mounted upon Serial No. 724,431. (No model.)

a base 13, which is in turn secured fixedly to the web 1 1 of a driving gear-wheel keyed or otherwise fixed to the shaft 6. The clutch ring 12 is preferably of oak, maple, or other similar wood, and when the flanges 9 and 10 are brought to bear thereagainst the drum- .hub and the parts supported thereby are caused to rotate with the shaft 6.

The hub 5 has a plurality of longitudinal ribs 15 upon its periphery which are adapted to prevent slipping of two series of alternately-disposed rings 16 and 17, of which the rings 16 are of oak or other similar wood disposed with the grain thereof radially of the drum-hub, said rings having the inner porof the peripheries of. the adjacent rings 16,

the curvature of the heads and the grooves of the successiverings being continuous transversely. that the innermost ring 16 lies against the flange 8, while the outermost ring' 16 lies against the clamping-plate 19, through which The rings 16 and 17 are so disposed and the rings 16 and 17, as also through the flange 8, is passed a series of clamping-bolts 20, through the medium of which the rings are: clamped in position, said ringshaving keyways corresponding to the ribs 15to re- .1

ceive thelatter and prevent rotation of the rings with respect to the hub 5.

As above mentioned, the hub 5 is mounted loosely upon the shaft 6, and in order to move it to carry the flanges 9 and 10, forming one clutch member, into engagement with the ring 12, forming the opposite clutch member, there is splined to the shaft 6 a collar 23, the end of which adjacent the hub 5 is frustoconical and is adapted to be moved into or out of engagement with a similar central recess 24 in the hub 5. This engagement of the collar with the hub acts to hold that/end of the hub concentric with the collar 23 which is itself concentric with the shaft 6. As there is no wearing movement of the collar 23 with respect to the shaft 6, said collar will at all times be concentric with the shaft, and. hence While the engaging surfaces of the collar and the drum-hub will wear to some extent this will only act to permit the collar entering the recess 24 to a further extent and will'not distnrb the concentric relation of the parts. The collar 23 is adapted to be moved into-and out of engagement with the drum-hub through the medium of a pulley 27, having a central longitudinalperforation provided with a bushing 26, having interior threads 28, "as

shown, said pulley, with its bushing, being mounted upon the shaft G'andwith the threads of the bushingin engagement with the threads 25, formed upon said shaft. Thus when the pulley 27 is rotated with respect to theshaft .6 it will move toward or away from thedrumin accordance'with. the direction of its-rotation. In .orderto move the collar 23 into-engagement with the drum-hub, with a minimum of frictionbetween said collar and pulley, there is-vformed corresponding races 30 and 31 in thecollar and pulley, respectively, in theform of hard-steelrings, which have cooperating grooves in which are disposed a se ries of balls 32, adapted to receive direct pressure-of saidrings, and therethrough of the pulley and collar.

Inorder to draw the collar from, engagement-with the drum hub, there is formed an annular outwardly-directed flange 33 atthe rear edge of the collar, and which flange, with- I theadjacent portions of the collar, enters a corresponding recess 35 in the adjacent 'face of; the pulley 27, and in which recess is formed an annular groove to receive the ring 7 3l, forming a race, as above described, the

opposite rin gBO'lyin g in a corresponding an,- nular-groove in the faceof: the'collar 23. i' A ring-36, encircling thecollar 23 and extend-- hig -inwardly beyond the outer edge of the flange33, isscrewed or otherwise secured to the-face of the pulley, and asthe pulley is moved away from. the drum this ring en.- gages-with the collar-flange and draws the collar with it.; f f

. In order to rotate the pulley with respect to the shaft 6 in either direction to cause it to", travel longitudinally thereof upon the i threads 28, there is. attached to the adjacent end of the shaft. agear-wheel40, meshing with a pinion,4l upon a shaft 42, the outer end'of'which has a ball-and-socket journal 43;, The;shaft,42'has also adjacent its oppoin thefstandard 44.

friction-pulley comprising a hub 50, having azflan-ge; at its outer end,.against which is 'clampedaplurality of rings52, mounted upon the hub andforming the engaging portion of theIfriction-roller. .The width of the groove 46 is slightly greater than the diameter of the roll 45, whereby said roll may be caused to alternately engage the outer and inner faces 47 and 48 thereof, respectively, under the influence of the lever 55.

The ends of the shaft 6 are provided with suitable hearings in supporting means for the mechanism, as shown.

The operation of this portion of the mechanism is as follows: The shaft 6 being rotated through the-medium-of the gear comprising theweb 14 or in any other desired manner to ?move the clutch into operative position, as

gshown in Fig. 3 of the drawings, the lever .is operated to throw the roller 45 into engageiment with the'outer face 47. of the" grooves 46, when the pulley 27 will bemoved" in the will travel along the shaft '6, throwing-the icollar 23 into engagement with the inner peiriphery of the recess 24 in the drum-hub, afiter which the drum will be movedlongitudinally of the shaft 6 and the innerfaces of the gfianges 9 and 10 will be engaged with the adja- Zcent faces of the ring 12, causing the drum to jrotate with thegear-wheel 56, which includes the web 14, and with the shaft 6.

In this op eration it will be understo'od'that the shaft 6 is fmoving in'the direction of the arrow 57"1J. 6., opposite to the direction of rotation ofthe ipulley 27 under the influence of the roller 45. Conversely, when the roller 45 is thrown into engagement with the inner face 48of thering 46 the diameter of the roller 45 being greater than that of the pinion 41 the pulley 27 will ibe rotated in the same direction as the shaft 26, but with its'adjacent engaging surface at a'greater speed, causing thelpulley to travel :down the threads 25' and draw the collar 23 gfromengagement with the drum-hub. The @ring 12 will then free itself from engagement ,with the drum due to the resistanceof the drum to rotation of the shaft '6 and the mechfanism will be in readiness for another cycle @of operation.

It will be readily understood that, if de- .sired, the shaft 6 may be rotated in any other desired manner, and it will be seen that the engaging surfaces of the drum and collar act to automatically center the drum at one end, while the clutch elements act'to center-at the opposite end, .and that the engaging elements fin their rotary motion have a self-grinding laction which acts to maintain their correlative shapes.

Hence, however badly worn the In the rig shown in Figs. 1 and 2 of the drawings there are employed two winding- ;drumswith their clutch and driving mechianisms, the gears 56 thereof being in mutual direction of the arrow shown in Fig. 3 and engagement, while the levers 55 have a common connecting-rod 60, having atone end an eccentric-strap 61 upon an eccentric 62, fixed to an oscillatory shaft 63, mounted in suitable bearings upon a sill 6% of the rig and provided with an operating-handle 65,through the medium of which lever-connecting mechanism the clutch mechanisms of the two drums may be simultaneously opera ted. The drum-shafts 6 are journaled in suitable bearings upon the sills 64 and 65 of the rig, upon which sills is also mounted a boiler 66, from which steam is supplied to the engines 67, having their pitmen 68 connected with the crank-pins or disks 69 upon a counter-shaft 70, carrying a pinion 71, meshing with one of the gears 56 and through the medium of which the drums are rotated. This pinion 71 is also adapted to be engaged at times by a gear 72 upon the shaft 73 of a drum 74, mounted in eccentric-block 75, having bearing in pillowblock 76, secured to or mounted upon the sills 64:. The eccentric-block 75 has fixed thereto a crank 77, through the medium of which said block maybe oscillated to move the gear 72 into and out of engagement with the pinion 71. The opposite end of theshaft 73 is journaled in a bearing 78, havinga balland-socket support. In the rear of the boiler 66 and upon the sills 64 and 65 are secured pillow-blocks 79 and 80,in which pillow-blocks 79 is mounted an oscillatory cylindrical bearing block 81, eccentrically mounted, in which is a shaft 82, the opposite end of which is journaled in the pillow-block 80. The block 81 is provided with a crank 83, through the medium of whichit may be oscillated to throw the friction-wheel Set of aslack-drum 85, applied upon the shaft 82, into and out of engagementwith a friction-wheel 86 upon the common driveshaft 87 of engines 88, mounted upon the sills 64 and 65, and which are fed from the boiler 66.

The length of the friction wheel or drum 86 is somewhat greater than the travel of the slack-drum longitudinally of the shaft 82, upon which latter the slack-drum is applied. It will be noted that the base of the boiler 66 is of a square type to permit a more compact arrangement of the parts of the structure, the engine 67 being of the horizontal style and located below the fire-door of the boiler; also, that the engines 88 are of a vertical style, and that the engines 88 have separate supplypipes from the engine 67 and also separate throttles. In practice when employing this rig with a single cable and double drum, as shown, the cable is brought inwardly and wound back and forth over the drums, as shown in Fig. 1 of the drawings in dotted lines, and is taken downwardly between the sills 64: and 65 and under guide- pulleys 90 and 91 to the drum S5. A trip-line or returnline 92 is attached to the outer end of the cable 93, and the inner end of this trip-line is secured to the drum 74, which is what is termed a trip-drum. The line 92 is of a length sufficient to reach from its drum outthe slack-drum with the drum 86.

wardly to the sheave or pulley, through which it is adapted to pass at the outer end of the zone of operation of the apparatus and back again to the point where the logs, hauled by the cable 93, are delivered. Thus when the cable 93 is drawn out to its full length substantially one-half the length of the line 92 will be wound upon the trip-drum and will be equal to or greater than the length of the. main or hauling cable 93. With the apparatus in this position, the lever 65 is operated to clutch the winding-drums upon their shafts, and the throttles of the engines 67 and SSare both opened, the crank 83 having been operated to engage the friction member 84: of

The winding-drums will then begin to haul upon the cable 93, and the engines 88 are given a sufficient amount of steam to maintain the cable taut between the winding-drums and the slack-drum, the throttle of the engines 88 being so set that with the maximum feed of' the winding-drums the speed of the slackdrum will be suificient to take up the slack of the cable. Thus the speed of rotation of the slack-drum will vary in accordance with the speed of the winding-drums, and this variation in speed will be automatic and will be incident to and in direct proportion with the rate of delivery of the slack. As the cable 93 is drawn in the trip-line 92 is paid out,- and when the cable is drawn in to the desired extent and it is desired to pay out'the cable the winding-drums are released from rotation with their shafts, and the gear 72 is moved into engagement with the adjacent gear or pinion 71, through the medium of which it will be operated to wind in the trip-line and haul the cable outwardly. It will thus be seen that instead-of winding the entire length of the hauling-cable upon itself when the usualstyle of winding-drum is employed the the winding-drums, the winding of the slack upon the slack-drum holding the cable with such looseness and with such absence of friction as to not materially wear it, thus greatly prolonging the life of the cable and efiecting a great saving in the wear and tear of the apparatus. i

It will of course be understood that, when desired, a single winding-drum may be substituted for the two drums shown, in which event the rings forming the outer surface of the winding-drum will be so disposed as to produce a helical groove in the periphery of the drum to allow a helical winding of the cable thereupon. It will be furthermore understood that any desired style of engine may be employed and that the throttles of the engines, as also the cranks S3 and 77, may have operating mechanisms extending to a common point adjacent the lever 65 to enable the entire mechanism to be operated by a single attendant. In practice also the guide pulley or sheave 91 is mounted for longitudinal movement with respect to its supportingsshaftf inord'er to allow the slack to swing from the guidevpulley 90, so that the slack between'th'e pulley 90 and the slack-drum 85' may lie at a sharper angle to the slack upon the drum should the longitudinal movement of the slack-drum upon theshaft be limited for any cause or-fi-om any cause. This, however, is immaterial, and the pulley 91 may be fixed against side movement, ifdesired.

It willbe seen from the foregoing description that by the employment of a system embodyingjjthis invention the diameters of the winding-drums remain the same, sotha-t' the leverage-of the drums is constant, as also'is their efiiciency.

In order to prevent the excessive movement of-fthe windi ng drum from the clutch-ring carried by the web 14, there-is arranged a small roller 100; suitably supported upon cross- 'bea n1s connecting the sills'64 and ina' positionto be engaged by the inner face of theflange 8 of the winding-drum, this engagement' preventing the opposite end of the winding druin engaging the collar 23 during the timethat the-cable is being drawn from the drum; This engagement would-unnecessarily wear the collar, and there might possibly'be an intermittent engagement of the drum with the 'collar with objectionable results, which will" be-appreciated'.' The upper ends of the spindles of the rollers 100 are braced by meansofbrace's' (shown in Fig. 2) and which are firmly secured to the cross-beams uponwhich the rollers are supported. 7
