Application filed March 8. 1909. Serial No. 481,931.

To all whom. it may concern:

Be it known that I. llAItltY X. CUVELL. a Q citizen of the United States. and a resident l tight door 4 arran ed to aflord easy access 55 to the interior of the housing or casing. A vertical shaft com weed of two sections 5 and 5 extends through the casing, the

f winch head 1 being keyed, or otherwise se- 3 cured to the. upper end of shaft 5. Atthe designed for use on the deck of a ship where j it. is customary to have a number of winches which may all he in use simultaneously, butwhich are more usually operated one or two or more at a time; in such cases it is desired that the heads of winches not in use be stationary, and it is provided by my invention that the winch is normally nun operating and the brake applied, operation being secured by the movement of a lever and being chccltetl automatically when the lexer is released.

In the drawings herewith I have shown and will hereafter describe a referred form of my invention as emboied in a vertical winch especially ada-ited for use n board a ship, but I do not csire to limit myself to such particular form or use but to cover any form of embodiment of my invention which consists in the arrangement, construction and operation of parts as set forth in and falling within the scope of the claims hereto appended.

Like characters of reference denote like arts in all the figures of the drawings ierewith.

Figure 1 represents a sectional side view in vertical elevation of the preferred form of my improved winch; Fig. 2 represents a side view in elevation,- a side of the winch housin or casing being removed and portions the niechanisni therein being shown in section; Fig. 3 represents a plan view taken throu h the winch housing or casing, 1ileegrtain hldtfill parts being shown in broken es. The preferred form of construction of my improved winch in detail is as follows: The winch head 1 is mounted on the top of a metll housing or casing 2, which 1s secured to a deck plate or other suitable support 3, end is provided with a water- 'tained in a timid position.

60 top of easing 2 the shaft section 5 passes through a bearing formed by casting Q,

which is preferably bahhitt lined or hushed.

To the l0\\'t-l' end of the shaft section 5 is key d. or otherwise secured, a metal disk 7. to the peripherv of which are bolted m'etallit: friction blot-ks 8, preferably formed "in M'glllt'nts and rhamfered or beveled at their lower outer edg s to form a suitable friction surface. he hub of the disk projects beyond the. lower end of the. shaft 5 to provide. a seat to receive the. upper end of the shaft section 5, in which hub or seat, the latter hait turns when the disk 7 is at restas her inafter set forth. all as shown at 231. metal rin; 5 is bolted to disk 7 extending: outward from the edge thereof and serving to take the shear or strain from the bolts whit-h secure the friction blocks 8 in place. metal di k 10 is mounted adjac nt the upper end of shaft section 5 being adapted to rotate with the shaft and. capable of \Plllmtl adjustment thereon by 11"?! of a feather on tile rllitl l; tln dink 10 is adapted to be in frictional engagement with friction blocks 8 when moved upward into contact therewith. At the bottom of the casing 2 shaft section 5' passes through a bearing (3 bolted to the casin and pref erably babbitt lined. A drive shift 11 untlerncath the deck I} is connected with and adapted to drive the shaft section 5 through bevel gears 12. At the bottom of easing 2 around the shaft .7 is placed a ring or cam. member 13 formed with an inclined ll))01 surface; said cam member being capa he of movement around the shaft but normally main- A second ring or cam member 14 with an inclined under surface rests upon cam member 13, being capable of movement around the shaft, am

when so turned, riding on cam 13 and being elevated or lowered in accordance with the direction in which it is turned.

Outside of the casingl is located a foot: lever 15 secured to a horizontal shaft 16 which extends through the side of the cusing. A ertical shaft 17 within the casing rests in lower and upper bearings l8 and 19, and is rotated by movement of the foot levcr l through the lTlQSllillQ' l)(\'l gear segments it! and "it secured to shafts it, aml 17 respectively. lever arm '1'. is secured to the shaft 17 and a lever arm '13 to the cam member H: joining levers and 2 3 and pivotallv secured to each is a connectin; link ".34. spiral spring secured to the bottom of the. casing 2' and to cum member l4. serves to ilot'ttiall retain .-aid member in its lowered position.

adjust ng arm 26 is pivotally secured toa lever arm projecting from the cam member 13, the nrm 2o passing through a flange and being adjusted in position b a boltthreaded upon its free end: by the adjustment of the arm .26 the cam member I3 i turned to give the desired elevation to the cam mer't r 1 when the latter rides upon the member 13; wea of the friction faces beim; thus compensated for and the cam member 13 being held in any desired fixed position.

spiral spring 27 between disks 1' and lb normally throws the disks apartand keeps the friction surfaces out of engagetuent.

Secured to the top of shaft- 17 is a brake toggle secured to which and adjustable by means of bolt 29 is a brake band Ito which encircles the upper portion of the per phery of the friction blocks The brake band 3t) is normally held in braking engagement with the blocks 8 by n'ieans of the spa-in; 2.. through its action on cam member H. which is connected to the shaft l? to which the surfaces are held out of engagenu-nt. by the action of spring 27, cam member l-l being held in its lowered position by spring 25 which also servcs to hold the brake band 30 in engagement with friction blocks 8, the

shaft section 5 remaining stationanv and shaftsection 5 revolving, if'power is applied to the shaft ll. \Vhcn itis desired to operate the winch head the foot lever 15 is depressed, releasing the brake 3t) and turning the cam member it against the action of spring 25, cam member It riding on the cam member 13 and being elevated thus forcing dish 10 up into frictional engagement with the blocks 8 against the action of the spring 27; the operation of the winch head being thereby secured. Upon releasing foot.

friction surfaoes separated, and brake applied automatically and operation of the. winch head ceases.

As above described it will be seen that l have provided a winch of novel design normally stationary, readily operated b the op eration of a lever, and automatically broug it to rest upon the release of the lever.

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