Be it-knovn that 1, WILLIAM A. E; HiiN- mo some of the United States, and a; 'residentr'oi' Boston, in the county of Suffolk and State of Massachusetts,- have invented on Improvement in "Clutches, of which the following description, in Connection with the I accompanying drawings, is e'specificetion',
iihe numerals on thedrmvings representing like parts. Q A
This invention relotes to that type of friction-clutch in which one clutch member is in the form of a. drumend' the other in the form of a 'frictionecoil encircling the drum;
A clutch embodying my invention will first be described, and then the novel feetu'res thereof will be pointed out'in the clitiits.

The'frictionmoil 4 or driving element of the clutch is driven from the shaft 5 by means obs driving member 8 which is fast to the shef t and within which the friction elements 3 and 4' of the clutch ore confined.
The ends of the lriction coil 4 are con- Specification of Letters Patent.

.nected to two collars 9 and 10, respectively; which' collars are loosely mounted upon the ,driven element 3 of the clutch. It'hese collars 9 end'lO are each shaped or 60 ;mbbeted,as at 11, to receive the'friction Preferably coil 4 and are each provided with a shoulder else has secured theretoandproecting therefrom an abutment 17, provide with a cam- 7 collars Bond 10 are oppositely disposed and and 21, respectively, carried by an actuator Thisclu'tch operating sleeve surrounds the driving member 8, es best seen in Figs. 1 and 2; and, is provided with 2. suitable groove 24, in which thefo'rk of a clutch-operating crin or lever 89' mev be received.
runningfree the ports are in I the position;
The rot otion of the shaft 5 -ives rotation to the driving member =8, and the latter, by engaging the 5 projection 15 of one or the Qth'crcolhir, de-
pending"; on the direction in whit-lithe driving meniher 8 is rotating, rotates soid collars and the friction-coil about the clutch element 3.
The resiliency ofthe friction-coil 4 is such too that normall it will unwind as much as the driving mom )er 8 will permit and will be suf ficioutly loose about the'druin 3 sothat it can freely turn thereztbout, and the tension o'f said lriction-coil is such that if the wall ofthe og slot 16 of the driving member engages a pro "4. jection 15 on one collar the rotation of said driving member will rotate said collar and through the coil. 4 rotate the-Other collar without winding said friction-coil suilicicntly ii 0 to'cause it to grip the drun1331; If,.fo1 1nstance. the shaft 51s rotating m such adrreo- I .tion that when the clutch is djsenga 'edthe wall of the slot 16 in the driving member 8 is in engagement with the projection of the collar 9, said collar will be caused to rotate,
thereby rotating the friction-coil 4' and the collar 10, the latter receiving its motion directly from the. friction-coil.
As, stated above, however, this coil is stifi enough so that the force required to give rotation to the collar 10 is notsuflicient to cause the coil to the coil is sufliciently 'ti ht'ened, the said drum will be driven from t e shaft 5, as will be obvious.
direction, thereby Withdrawing the earns 20 and 21 from the abutments 17 and permitting the resiliency of the friction=coil 4 to unwind the latter sufiicientl from the drum 3 to ermi't it to run loose t ereon.
' ne end of the actuator '22 rests againz't a Suitable adjustin -screw 30, so that as wear occurs between t e cam-surfaces 20 '21 and the corresponding abutments such wear may the driving member 8 it is thereby be taken u by setting up said screw slightly.
Preferab y I will make the interior diameter of the driving member 8 just sufficiently larger than the exterior diameter of the drum 3 to admit the friction-coil 4 loosely, and said coil is so constructed that it will tend to ex- Hand to a larger diameter than the interior iameter of the driving member '8. The result is that when the clutch members are disengaged from each other the coil sis permitto to unwind by its resiliency only sufficiently to release the drum 3'; but when it comes in contact with the interior surface "of prevented from further unwinding.
It will be noted that in this embodiment of .my invention both ends of the iriction coils are free to be moved relative to both the drum and the driving element of the clutch or the shaft 5 and that the actuator acts upon both ends of'the coil and tightens it from both ends.
" ;Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-' 1. In a clutch, a drivin member, a driven member, a, drum rigid wit 'one of. said members, two collars rotated by the other member but capable of turning relative to each other,
- a friction-coil encirclin the drum and having one end fast to each 00 er, and means to turn To unclutch the clutch mem-- bers, the sleeve 23 is moved in the opposite the collars in opposite directions, thereby -to tighten the 'coil at both ends about the drum.
2. In a clutch, a driving member, a driven member, a drum rigid with one -member, a friction-coil encircling the drum and connected with the other'member to rotate there with, both ends of'the coil being free to be i moved relative to said member, and means to.
' 4. A clutch comprising a drum, a hictioncoil encircling the drum, two loosely mounted collars, each ,connected to an end of the coil and each carrying an abutment, an actuator having two cam surfao'es, one to act oneach abutment, and means to move the actuator thereby to give the collars a relative movement in'opposite'directi'ons. I
v5. In a clutch, a shaft, ca 'frictiomdrum loosely mounted thereon, a friction 'co'ii encircling the drum, loosely-mounted oollar's to which the ends of the i'riction coi'l are secured,
means to rotate the collars in the same .direction from the shalt, and a -'clutch-actuator to give the collars a relative turning'movement' in opgos-ite directions.
n a clutch, a shatt, a drum loosely mounted thereon "a iric'tionwoil surrounding the drum, two loosely-mounted collars to which the ends of the coii are connected, a driving member fast to the shaft and hidesing the drum and friction coi'l, said collars having projections to be enga ed by the driving member, whereby the co lars are driven thereby, and means to give the collars a rela- .tive 'turnin movement in opposite directions, there 'y to wind the friction-cod onto' thedrum. a
'7. In a 'clutch, a shaft, adifnm loosely mounted thereon, a irictiomc'oi'l surrounding the drum, two loosely-mounted collars to which the ends of the coil are "connected, a driving member fast to the shaft and in'closing the drum and hiction-coi'l, said collars having projections to be enga ed by the driving member, whereby the co ars are driven thereby, a sleeve slida'blyinountedpnthe drivin member and carryin means to en-- gage t e collars, whereby sli 'ng movement, of the sleeve turnsthe 'collars in opposite =d-irections.
In testimony whereof I have signed my name to'this specification in the presence of two subscribing witnesses.
