CLUTCH.

Be it known that 1:, EDWARD H. BUGKLEY, a citizen ofthe United States, and a vresident of Caledonia, in the county of Houston andState of Minnesota, have made certain new and useful Improvements in Clutches,

of which the following is a specification.v y My invention relates to clutches, my more particular purpose being to provide,r an vim#` proved clutch adapted for use with a hay n hoist of thekindv actuated by aid yof a horse,

and in which the sweep or driven element of the clutch may be disconnected from the windingqdrum or ydriven element by a person accompanyingn'the load to be hoisted, such person being at a distance fromlthe sweep. f i

VMore particularly stated, kmy invention comprehends a clutch providing ay revoluble drum, and with afircable" to bewound by the rotation of said drum, a sweep normally connected with the drum for turning thel same, and disconnecting mechanism control-4. ,lable at a distance, and of special construe-l tion for rendering certain and positive .the

disconnection of the sweep.

Reference ismade to the accompanying drawing forming a part of this specification, and in which. like letters` indicate like parts Figurel is a side elevation ofy the sweep and drum, and parts immediately associated therewith. Fig. 2 is a plan view of the Fig. 3l is av substantially central vertical section throughl mechanism shown in Fig. `1.

the mechanism shown in Figs. 1 and` 2.

A pairof sills are shown at 4, and extending upwardly from the latter are posts 5. Secured tovthese posts are sidebeams 6. A. cross beamf? extends fromV one of the side beams 6 to the other. A revoluble drum is shown at 8 and is mounted upon a journal 9, the Ilatter being secured rigidly upon a cross beam 1,0 forming a part of the framework.

Rollers are shown at 11 and 12, andare revoluble relatively to the `franii-iwork vwhereby they are supported. The journal.

9 is provided with a reduced portion 13, having the form of a` stem, and extending directly upward. The drum 8' is provided with notchesk 14 arranged in the form of a circle, and spaced apart equidistantly, las indicated in Fig. 2. The notches 14 and parts bounded thereby constitute an annular rack. sweep is shown at 15 and is Slpeci-caton'of Letters lPatcifit.l i

y. provided hole which stem. 13, so that the sweep may turn rela,

tively to -the stem. The sweep 15, is fur# ther provided fwith van, opening 17. Mountn' 1 ed upon the sweep is abracket 18 and ex`-:

tending A,through this bracket `and pivotally 5 supported, thereby, is a` lever.V 19. vThis `lever is Lprovided with a toe portion 2O which extends through the opening.:` 17 landfisy adapted tofit intoany` one o ftthe notches. 14. The lever; I19 `is provided with a fork` f 21 through; which .ithev stem 13 extends." c Aspiralspringr22 encircles thestemfli and engages ltlienforky y21,y this. spring also engagingf-- they adjacent` portion of *tlief sweep 15. QA. sleeve 23 encirclesthestem 13 andl rests upon the fork 21. A cam lever 26 extends directly throughr the stem [13, `which visislottedi'for.thisfpuiposey and -is providedlf with a cainsurface28. Thesleeve'23 is pro! f .vided with `a raised portion24, the latter f "being providedywithya slot ,25. into, which..

the calm lever 26 `may extend as indicated in 1 Fig. 3. i i.

A cord29 is connectedwith the ycam `lever 26 and engages a pulley 30.y This pulleyis f.

mounted upon a pivot pin 31. Urlhe yhoistiifig line 82 is partially wound upon the drum `8f and engages' the rollers 11, 12,for' the purpose'of guiding the'line.` n The hoisting line 32 is employed for raising the weight to"v be lifted which consist ofl a` quantityof hay or thelike.` The operatoiaccompanying the load may, by

pulling upon the rope 29, rock the 'cam lever 26, and in doingthis inaydepress the fork 21 andfthus actuate the lever 19 so as to lift the toe portion 2O` ofl this lever out of@ thenotch 14 in which` it happens to be at the time.v f

, .The operation of my device is followsi Theyparts being, assembled and arranged as above indicated, the'cord 29 is slackened so y' *y ;i0o

that the pressure of thespring'22 by acting upon the lever 19 causes the "toe portion 2O of this lever to enter some one `of the notches 14. lThis being done, the sweep i155 isc'on- `nected positively with the drum 8, and horses c or other draft animals being harnessedto the sweep now turn the sweep sok as torotate thefdriim 8.

raised. The voperator now" pulls upon the hoisting line 29`so as to rock the lever 26.

The hoisting line is thus wound up and the load is accordingly j n, K

iio

This forces thesleeve 23 downwardly, coinpresses the spring22, causes the lever 19 "to ving a rigidly mounted 4journal having a portion forming a stem, a driven element rev- 1 rock, andas a consequence this lever is disconnected from kthe drum 8, as above described.

Only one man is necessary in order t0 operate my device. Even in instances where it is desirable to employ two hands, the device still saves the work of one additional hand, otherwise employedA to stop the travel ofthe horse. By disconnecting the sweep from the drum7 the continued travel of the horse can have no eifect uponth'e winding mechanism. f

By making the stem 18 integral with the journal 9, and mounting thel cam lever 26 L upon the stem 13, the construction of. thel of my invention, the scope of which is commensurate with my claims.

I claim y 1'., A device of the class described comprisolubly mounted upon the ournal, a4 driving velement revolubly mounted upon the stem,

member on the stem and engaging the bifurcated end 0f the lever, a sleeve loose on the `stem and also engaging lthe lever, and a cam lever carried by the stem for actuating the sleeve.

2. A device of the class described comprising a fixed shaft, a driven element rev- 2Aolubly mounted thereon, a driving element also revolubly 4mounted thereon, a lever mounted-,cn the driving-element and having n means for engaging the driven element for locking the driving and driven elements together, said lever being provided with a. i bifurcated portion straddling the shaft, and

means on the shaft adapted -to coperate Iwith?theloifurcated portion for actuating the lever.
