HERBERT L. PHILLIPS, OF SEATTLE, WASHINGTON.

HAULING AND HOISTING APPARATUS.

To all whom it may concern:

Be it known that I, HERBERT L. PHILLIPS, a citizen of the United States of America, and a resident of the city of Seattle, in the lcounty of King and State of WVashington,

have invented certain new and useful Improvements in Hauling and Hoisting Apparatus, of which the following is a specification.

My invention has particular reference to variable speed mechanism for transmitting power to hauling or hoisting cables.

The primary aim of the invention is to provide a compactly arranged mechanism of the above type embodying diiferential winding gearing, and adjustable features involving an improved application of power.

Further objects and advantages will be set forth in the following description, and those features on which I desire protection, succinctly defined in the appended claims.

With reference to the accompanying drawings, wherein similar reference characters designate corresponding parts throughout: Figure 1 illustrates, in plan view, a preferred form of mechanism, embodying the features of my invention. Fig. 2 is a front elevation of the same in partial section. Fig. 3 is a sectional elevation, taken on line 33 of Fig. 1, and Fig. 1 illustrates a portable logging apparatus, em-

'bodying my invention, engaged in pulling a stump.

Referring now to the drawings, numeral 1 designates a drum having hub extensions journaled on a frame 3, and 2 indicates a second drum likewise mounted on said frame and secured for rotation with a spur gear 4 and a shaft 5.

Journaled in the hubs of drum 1, is a spindle 6 secured to a gear wheel 7, meshing with a pinion fixedly mounted on a shaft 9, journalecl on frame 3 and secured for rotation with bevel gear wheels 10 and 11 of unequal pitch diameters.

Meshing with wheels 10 and 11 respectively are pinions 10 and 11 loosely mounted on a drive shaft 12, which may constitute the power shaft of a reversible motor or engine mechanism of suitable type, designated at 13 in Fig. 4c.

Pinions 10' and 11, as shown, are provlded w1th clutch counter-parts for engagement'with clutch members 10 and 11 respectively which are secured for rotation with shaft 12 by suitable feathers or the like,

Specification of Letters Patent.

and suitably connected with respective shifters, as 10 and 11, fulcrumed on a cross piece 30 of frame 3, whereby shaft 12 may be connected with either of said pinions.

In conjunction with spindle '6 I provide releasable means for connecting the same with either drum 1 or 2 or with both of said drums, as may be desired, the said means, as shown, including a double clutch member 60, slidably engaged with a squared portion 6 of spindle 6, and clutch counter-parts 61 and 62, provided respectively on the adjacent hub of drum 1 and on a spur gear 40 meshing with gear 1 and bored to receive the hub of member freely. For adjusting the clutch, just described, I have shown rock arms 40 and 60, mounted on frame 3 in connection with handles 63 and 63 respectively, and having link connections with respective rings loosely engaged in annular grooves provided in the hubs of gear 10 and member 60. By this arrangement member 60 may be adjusted, by proper manipulation of handle 63, to engage it with either counter-part, as may be desired, to connect spindle 6 with drum 1 or with gear 40 to drive drum 2, and when member 60 is engaged with counter-part 61, gear 40 may be adjusted by manipulating handle 63 to engage counter-part 62 with said member and thereby connect the spindle with both drums. Provision is also made for operating drum 2 through the medium of helicoidal gearing which, as shown, comprises a worm wheel 50, loosely mounted on shaft 5, and a worm 51 meshing with said wheel and secured to a shaft 52 journaled on frame 3 and rotatable with a spur gear wheel 53, meshing with a loose pinion 54 on shaft 12.

Wheel 50 and pinion 54 are each provided with suitable clutch counter-parts for engagement with adjacent clutch members, as 50 and 54:, held for rotation with shafts 5 and 12 respectively by means of suitable feathers or the like. Member 54 is suitably connected with a shifter 54, fulcrumed on frame part 30, and member 50 is connected, by means of a loose ring and links, with rock arms 55, mounted on frame 3 in connection with a handle 65, as clearly shown.

The helicoidal gearing, just described, may be used as means for locking drum 2 from rotation in either direction by engaging clutch member 50 with its counter-part on wheel 50, and when said member is thus engaged, driving connection with shaft 12 may be effected by engaging clutch member 54: with its counter-part, as will be clearly understood. If it is desired to connect both of the drums with this gearing, gear 4L0 is connected with spindle 6 in the manner heretofore described and clutch member 50 con nected with wheel 50, as above set forth.

Suitable provision should be made for restraining the drums from back action and for this purpose I have shown oppositely disposed spring pressed pawls 22 and 23, pivotally mounted on frame 3 for engagement with respective sets of ratchet teeth provided on drums 1 and 2, (see Figs. 1 and 2). These pawls are connected with respec tive draw rods 24, having screw threaded engagement with hand wheels 25 for adjustment to move the pawls clear of their ratchet teeth. In the case of pawl 23, the stem thereof is jointed or articulated and the outer or spring pressed portion 23 pivoted to frame 8 so that the arrangement of the adjusting mechanism just described may be the same as in the case of pawl 22.

Reference numeral 26 indicates a band wheel secured to shaft 12 and provided with a notched flange for engagement with a dog,

as 27, pivoted on frame piece 30. Extend.-

ing about wheel 26 is a friction band 28, connected with a rock arm 28 mounted on frame plece 30 and having link connection with a foot lever 29 for operation to apply said band to wheel 26 when it is-desired to obtain a braking effect.

42 designates fair leaders for the cable, conveniently in the form of rollers mounted on respective brackets 43 of frame 3 forwardly of the end portions of the drums.

In applying the apparatus as disclosed in Fig. 41, drums 1 and 2 are connected with respective ends of the pulling cable 44, which is then engaged with a block, as 415, made fast to the stump to be pulled. Clutch member is then shifted to engage it with counter-part 61, and member 11 likewise connected with its counter-part on pinion 11. Power is then applied to shaft 12 to rotate drum 1 in the direction indicated by the arrow in Fig. 1, to take up the slack in the cable, when clutch member 11 is thrown out and clutch member 10* engaged with its counter-part on pinion 10 for application of the power through gear wheel 10. Should the power as thus applied be insufficient to start the stump, it may be applied with greater effect through the medium of both drums. In this connection it should be observed that the diameters of drums 1 and 2 are preferably equal while the pitch diameters of gears 40 and 4: are unequal. Therefore, a difierential ulling eflfect may be obtained when the rums are connected, by operating the same to play out the cable from drum 1 and take it up on drum 2. In

the present described oaeration, this would be efi'ected by first shi ting gear 40 to engage counter-part 62 with member 60, and adjusting pawl 22 to release drum 1 for operation in a reverse direction to that before described for take up of the cable.

The helicoidal gearing is especially useful where a nicety of ad ustment is required in placing the load, as for example. when the apparatus is employed in installing structural members, or when it is essential to impart a slow uniform hauling motion to the drums. The application of the apparatus in this respect would obviously vary in accordance with existing conditions. Assuming however, that the load-is first moved close to a desired position by application of the power to drum 1 through gear 10 and attendant mechanism, as hereinbefore described, further application of the power may be made through the helicoidal gearing to operate drum In this event, clutch members 50 and 54/ are first shifted to engage with their respective counter-parts and member 1O shifted from engagement with its counter-part.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is
