WITNESSES INVEWTOR 4 have invented a certain new and useful UNITED STATES PATENT OFFICE. I

CHARLES B. KING, OF DETROIT, MICHIGAN, ASSIGNOR TO NORTHERN MOTOR CAR COMPANY, OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN.

CLUTCH.

To all whom 'it may concern: Be it known that 1, CHARLES B. KING, a citizen of the United States, residing at Detroit, county of Wayne, ;State of Michi an,

rovement in 'Clutches, and declare the. following to be a full,'clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to clutches, and the object of my improvements is to provide an improved clutch. mechanism and one in which the operative parts of a motor and transmission mechanism may be connected and disconnected.

In the drawings :--Figure 1, is an elevation of a gas engine and transmission mechanism embodying my invention. Fig. 2, is a detail sectional view of the valve H Fi 3,1 is a sectional view of the main shaft 0 the engine, thefly-wheel and some adjacent parts. Fig. 4-, is a erspective view of the dlsk G and sleeve A, A, are the cylinders; B, is the crank case and C, the fly-wheel.

E, is the main shaft of the engine. 1

I form an aperture H through the cylinder and provide a pipe H leading therefrom.

-- The aperture H may be below the upper end of the piston stroke or it may be in the explosion chamber.

H is a non-return valve in the i pe H 1% come municates with a reservoir When the engine is working}, there is a considerable ressure in the cy der and the gases there fore pass through said opening past the valve H into the pipe H andf accumulate and cause a pressure in the tank H gree of such pressure may be regulated by the osition of the openin T ough the main shaft ,is formed a assage e, which extends from end to end o the crank shaft-and through the cranks.

F, are fan blades in the fly-wheel C. Within the fly-wheel and-supp0rtedcm axially therewith by said fan-blades is a cylinder G closed at its inner end. The passage e communicates with the interior of thecylinder G through a passage at the center of its closed end. p

. G, is a diaphragm preferably of leather,

its periphery resting upon an annular shoulder within. the cylinder G. v

G, is a collar fitting within the cylinder G, its inner edge coming .against the periphery of the. diaphragm G and holding it in place against the annular shoulder in said cylinv der. The inner edgeof the collar G is preferably provided with a bead g; The outer edge of the collar G is turned over'and secured by screws g extending into the edge of the wall of thecylinder G and serving to secure, and draw said collar tight against the edge of the diaphragmG From the collar G a flange G extends inward and then outward to form a sleeve G 4 9 is a leather annulus secured to the inner face-of the flan e G G is a meta disk within the cylinder G between the diaphragm'Gr and the flange G.

G, is a shaft to which the power of the engine is to be transmitted.

G, is a sleeve surrounding the shaft G the inner wal of the sleeve G".

- g", are pins extending from the-shaft G into the slots 9 connected to the disk G 9 is a bushing between the sleeves G g, are 1011 itudinal slots extending into The sleeve G is rigidly cylinder G, or may be exhausted from said assage and cylinder to the open air or may: he led to a brake operating cylinder H and exhausted therefrom.-

hi is a handle by which the valve H may be manipulated.

H is a pi e communicating with the pipe H at one on bending upward-and communieating with a pipe H, which asses through a stuffingbox in the end of t e crank shaft and communicates with the passage e through the crank shaft E. H7, is a'set screw by which the pipe H is secured in position.

By turning the handle if, so as to allow a free passage through the pipe H com ressed air or gases is caused to pass through t e pas sage e into the cylinder G pressing the disk G a ainst the flange G and therefore binding t e sleeve G 'and shaft G to the shaft E. By turning the handle 72 so as to cause the pipe H beyond the valve H 'to communicate I 'with the outer air, thenoinpressed gases are discharged from the cylinder G through the assage e, releasing tlaFgdnnection between shafts G and E.

What I claim is I 1. In a clutch mechanism, the combination of a cylinder having one end closed, a

flange fixed to the edge of said cylinder around its open end and extending part way to the center, a disk'in said cylinder between said flange and the end of said cylinder, means for connecting said disk toward its center with the transmission mechanism, and

means for sup ying fluid under pressure to 1 1 said cylinder ack of said disk to press it against said flange to bind vsaid disk and flange together for the urpose described.

2. In a clutch meciianlsm, the combination of a'cylinder having one end closed, a flange fixed to said cylinder at the edge surroundingits open end and extending partway to the center, the said flangabein provided with an annular coaxial outward y extending sleeve, a disk in said cylinder between said flange and the end of the cylinder,

' tion of a cylinder having one end'closed, a

flange fixed to said cylinder, a disk in said cylinder between said flange and the end of 'said cylinder, said disk being provided with a central rojection extending beyond said 5 projection being provided with a central. longitudinal aperture, and a longitudinal slot in its wall, a shaft projecting into said central aperture provided with a lug extending into said slot, and means for supplying fluid under pressure to said cylinder back of said-disk' to press it against said flange for, v

the purpose described. 4. In a clutchmechanism, the combination of a cylinder having one end closed, a

flange fixed to said cylinder provided with an tween said disk and shaft an 'flange fixed to said cy annular coaxial outwardly extending sleeve, a disk in said cylinder between'said flange and the end of the cylinde'nsaid. disk beingprovided with a central projection extending beyond said flange in said sleeve, said projection being provided with acentral aperture and a longitudinal slot in its wall, a shaft extending into said aperture and rovidedwith a lug extendin into said s 0t, and means for supplying uid under pressure to said cylinder ack of said disk to press it against said flange for the purpose described. 15- In' a clutch mechanism, the combination of ac flinder having one end closed, a flange-fixe to saidcylinder, a disk in said cylinder between said flange-and the end of said cylinder, means for sup lying fluidunder pressure to said cylinder ack of said disk to ress it against said flange,and a v shaft, said disk being connected to said shaft so as to restrainv relative rotar to permita" motion of said disk in the direction ot the length of said shaft. 6. In a 'clutch mechanism, the combination of Y a'cylinder having one end closed, a inder at its edgearound its 0 en'ed end, a diskin said cylinder ,between sai flange and the end of said cylinder, means for su plyin fluid under pressure to said cylinder l a ack 0% said disk to press it against said flan e to bind said cylinder and dlsk together, an a transmission mechanism, saiddisk bein connected towardsits center adjacent to tie open end of said cylinder with the-transmission mechanism so as to restrain relative rotary motion between said disk and transmission mechanism and to permit a motion of said disk relative to said cylinder in the direction of the axis of said cylinder, for the'purpose described.

In testimony whereof, I sign cation in the presenceof two witnesscs.-
