T0 LZZ whom t muy' concern:

Be it known that I, I-IAWKEN P. HANSEN, a citizen of the United States of America, resid ing at Decorah, in the county of Winneshiek,

is a view of the upper end of the drum, and v Figs. 6 and 7 are detail views.

My invention is in the nature of an improvement upon the power-winch invented by John W. Pope and William C. Meyrick, for which application for Letters Patent of the United States was iiled April 25, 1898, Serial No. 678,758. The winch there shown is intended for trying and difticult'worksuch, for example, as stump-pulling-and is provided with effective means for the temporary engagement of the sweep with the winding-drum, the connection being so made that the sweep may be retracted when necessary or desirable in order to secure an engagement that will prove more accommodating to the location or the power attached to the sweep. No means, however, is shown in that application for taking upV the slack of the winding-rope by rotating the drum independently of the sweep.

The object of this invention is to provide a winch of the general type of that shown in the Pope and Meyrick application with simple and effective means for rotating the drum independently of the sweep whenever it may be desired to take up the slack of the winding-rope or for other similar purposes.

To this end my invention consists in the novel construction and'combination of the parts shown and described, and more particularly pointed out in the claims.

In the drawings, A represents the winding- 5o drum suitably positioned between the plates `B B', which are held iu proper relative position by posts Qc y z. The upper end of the winding-drum A extends through a suitable opening in the plate B, forming a bearing for the same, and is provided with thev ratchetface a a' a2. The sweep C is provided with a cap C', adapted tol encircle the top of the, drum, as shown, and is rotatably secured to .the plate B in any preferred manner-as, for 6o example, by the castings D, secured to the plate B and embracing the shoulders c c on the cap C. The clutch or lock block F is adapted to be positioned within the cap C and is provided with guideways F', adapted 65 to coact with the guides C2 in the cap, causing the clutch-block while vertically movable within the cap to also be always so engaged with the sweep that it will positively rotate therewith. This construction permits 7o of a vertical movement of the block F, which when the sweep is reversed permits the block to rise and the shoulders f f f2 to ride over the ratchets a a a2, after which the block will drop again into position and become suitably engaged with the head of the winding-drum to operate the same. A clutch or ratchethead G or an equivalent device is loosely positioned in the lower face of the block F in such a manner that it may be rotated inde- 8o pendently thereof. A rod or bar E, extending from the ratchet-headG through the sweep C, is provided with suitable means for rotating said bar and the ratchet-head G. As here shown, the hand-wheel H serves this purpose. 8 5 The rod or bar E loosely extends through said wheel H in such a manner that it cannot ro- -tate therein, but the two rotate in unison. A squared or irregular-shaped rod or bar passing through a corresponding opening in the 9o wheel serves this purpose. The bar E is provided at its upper end with the cam-,lever I, by the operation of which the ratchet-head G and the block F may be vertically lifted to disengage them from the head of the winding-drum, Fig. 2. The upper end of the winding-drum is provided with suitable means for engagement with the ratchet-head G. Fig. 5

shows means for this purpose in the lugs K. Ratchet-and-pawl connection pre vents the accidental reversal of the drum.

The operation of the device is as follows: The winch being suitably anchored, as by the anchor-line M, and the lines properly connected, the cam-lever I is thrown over to assume the position shown in dot-lines, Fig. 2. The lock-block F thus engages with the head of the winding-drum and the ratchethead G with the lugs K. If at this time the winding-iopes L are slack, the drum may be independentlyrotated by means of the wheel H and the engagement of the bar E and ratchet-head Gwith the lugs K in the drum, the lock-block F riding over the ratchet-s a a c2. lVhen the slack is taken up, the sweep may at once be operated, the engagement iinmediately changing from that just described to the cap, the lock-block, and ratchet d a a2 in the drum.

When the cam-lever I is thrown over into the position shown in full lines, Fig. 2, the bar E is raised, disengaging the head G and lock-block F from the drum and disengaging the sweep therefrom. The ratchet O and pawl P may then be disengaged, when the drum is entirely released and free to rotate in either direction.

I do not wish' to be understood as limiting myself to the exact construction shown, the broad idea of my invention consisting in providing a supplemental connection with the drum by means of which it may be rotated independently of the sweep when no great strain is on the lines, resulting in a great saving in time.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In a device of the kind described, a winding-drum, a main clutch adapted to engage the drum, and means for rotating the clutch, in combination with a supplemental clutch device adapted to move said main clutch into and out of engagement with said drum and adapted to engage and turn the drum independently of the main clutch, whereby the drum may be rotated independently of the main clutch device, substantially as described.

2. In a device of the kind deseribed,the combination of a winding-drum, a rotatable cap, means for rotating the cap, a clutch-block movably carried by said cap for coupling the cap to the drum, a supplemental clutch adaptcd to engage the drum and turn the same independently of the main clutch, and means for movingthe main and supplemental clutches to engage the drum, substantially as described.

3. In a device of the kind described,the combination of awinding-drum, a rotatable cap, means for rotating the cap, a main clutchblock carried by said cap for coupling the cap to the dru m,a supplemental clutch-block movable with said main clutch-block toward the drum, and means for rotating said supplemental clutch-block and drum independently of the main clutch-block, substantially as described.
