' Application filed November 7, 1883. (No model.)

To all whom it may concern.-

Be it known that we, WILLIAM LEVERTON BEA'r'rY, HARVEY LEGRAND BEATTY, and ALVIN OSCAR BEATTY, allmanufacturers, and all of the town of Welland, in the county of W'elland, in the Province of Ontario, Canada, have jointly invented certainnew and useful Improvements in Hoisting-Machines; and we do hereby declare that the following is a full, clear, and exact description of the same.

The invent'ionrelates to that class of hoisting-machines in which the rope-drum is connected to the driving-axle by an adjustable friction-clutch;'and the object of the'invention is to improve the form and construction of the friction-clutch, and also to devise simple mechanism by which the speed of the ropedrum can be increased without altering the speed of the driving-axle. 1

Figure l is a perspective view of our improved hoisting-machine. Fig. 2 isa perspective end view, showing the gearing for in creasing the speed of the ropedrum. Fig. 3 is a sectional detail, showing the form of friction-clutch for connectingthe drum to the machinery for increasing its speed. Fig. 4 is a sectional detail of the friction-clutch for form-v ing a direct connection between the drivingshaft and rope-drum. Fig. 5; is a front detail View of the disk, showing the form of octagonal flange, with the blocks of wood attached to it. Fig. 6 is a front view of the fastspeed drivinggear, showing the form of the cam-adjuster for throwing it inand out of gear. Fig. 7 is a plan of our machine, showing the fast-speed clutch mechanism in section. Fig. 8 is a longitudinal sectional elevation of our machine.

We have shown a number of different views of our machine, in order to fully illustrate our invention; but for the general purpose of this specification, Figs. 7 and 8 will mostly be referred to, unless the other figures are specifically designated.

A is the rope-drum driving-axle, suitably journaled at either end on the pedestals B, which form part of the main frame of the machine. We have shown two rope-drums, G,

" on the axle A; but it will be understood from the drawings that one of these rope-drums might be dispensed with without altering our invention, and therefore, although we may only speak of one drum and its connections, it will be understood that one ismerely aduplicate of the other, and, so far as its connections with the driving-axle or otherdriving-gear is concerned, one, two, orzmore drums with connections might be used in the hoisting-machine without altering the general arrangement of our invention. The rope-drum Ois journaled loosely onithe axle A; butits inner flange has a recessed head, D, shaped to form the'female half of the'friction-clutch, the other half of the clutch being formed, as hereinafter described, on the disk E, which isikeyed or otherwisezrigidly fastened toithe driving-axlev A. A'beveled-gear wheel, F, is formed upon or attached to one side of the disk E,-and is arranged to mesh with thelloeveled pinion G,

which is fastened to the vertical shaft H. This latter shaft is properly jo'urnaled in and sup-' ported by the bracket I, which forms part of themain frame of the machine. The vertical" shaft H derives its motion from any suitable motor; andv through its connection described with the axle 'A the motion of the drivingmotor is conveyed to the rope-drum drivingaxle A. So long as the connectionbetween the recessed head D and. the disk E is broken, the axle A will revolve without communicating motion to the drum, unless the said drum is connected to the shaft by the fast-driving gear, which we will describe hereinafter.

On reference to Figs. 4, 5, and 8 the construction of the friction-face of the disk E will be understood. This disk E has a flange, 6, extending outwardly at right angles from its surface and a'short distance below its periphery. This flange is octagonal in shape, and is designed to receive a block of wood, f, on each octagonal side. The said blocks, when bolted in position, as shown in Fig. 4., are arranged so that the-grain of the wood shall extend outwardly toward the periphery of the disk. The blocks are then turned down on a bevel extending from the periphery of the disk toward the outer edge of the flange c, the bevel of the blocks being formed to correspond with and fit into the conically-recessed head D- This form of clutch is exceptionally strong. The octagonal shape of the disk constitutes a substantial IOO seat for each block, which tends to hold each block in position and relieves in a great measure the strain which the bolts used for securing the blocks to the disks would otherwise be called upon to sustain.

On reference to Fig. 8 it will be noticed that we make an elongated keyway, J, through the axle A, at the outer end of the drum 0. This keyway has fitted into it a key, K, which passes through a collar adj ustabl y fitted on the driving-axle A, but prevented from revolving thereon by the key K. The elongated keyway J permits the longitudinal adjustment of the key K and the collar L, connected to it. This longitudinal adjustment is effected by the spindle M, which fits into a hole in the axle A, extending from its end to the keyway J, as shown in Fig. 8. The outer end of this spindle M bears against the screw m, which fits into a nut, N, formed in or attached to the frame of the machine, as shown. It will thus be seen that by turning the screw m the pressure imparted by it through the spindle M against the key K is transferred through the collar L to the end of the rope-drum G, causing the rope-drum to move longitudinally upon the axle A, forcing its conically-recessed head D onto the disk E, thereby effecting a frictionclutch between the drum 0 and the said disk E, which friction-clutch causes the drum 0 to revolve with the axle A, as before specified.

\Vith the view of enabling the ready adjustment of the spindle M we attach to the outer end of the screw in an arm, 0. This arm 0 is connected by the rod 1 to the rock-shalt Q, which rock-shaft is journaled in the front of the frame of the machine, as shown in Fig. 1, and is provided with. a suitable handle for rocking it in its journal, which rocking motion is sufficient to turn the screw in its nut, in order to impart the desired adjustment to the drum, as specified.

The connection herein described between the drum G and disk E is made, as specified, when it is desired to use the drum for hoisting a weight.

In order to run the drum quicker, with the View of taking up slack or for any other purpose, the connection between the drum 0 and disk E is broken, when, by throwing the fastspeed gear, which we shall now describe, into connection with the drum, the said drum is caused to revolve at the desired high speed.

Figs. 2, 3, 6, and 7 exhibit the arrangement and construction ofthe fast-driving gear.

A gear-wheel, R, is keyed or otherwise fastened to the axle A. This gear-wheel is arranged to mesh with the pinion S, keyed or otherwise fastened to the counter-shalt T, which counter-shaft is suitably journaled in brackets attached to the frame of the machine, as represented. A beveled disk, U, is also fastened to the counter-shaft T. This beveled disk is designed to fit into' the conically-recessed disk V, which disk revolves freely on the counter-shaft T, unless a friction-clutch is formed between it and the beveled disk U. A spur-whceLlV, is either connected to or formed upon the disk V, which spur-wheel meshes with the pinion X, which is fastened to the drum 0, as shown. From this description it will be seen that when the connection between the drum 0 and the disk E is broken and a clutch-connection formed between the disks U and Vthe speed of the drum will be greater than the speed of the axle A, which speed is according to the relative sizes of the gear-.

ing connecting the axle A, through the counter-shaft T, to the drum G. In order to effect this connection between the disks U and V easily and-effectnally, we provide a handle, Y, which is attached, as shown, to a cam-faced collar, Z, jonrnaled on the counter-shaft T. The face of this cam-faced collar Z is arranged to work against a similarly-formed cam on the frame of the machine, so that by turning the cam-faced collar Z by its handle Y the collar Z is pushed away front the frame from the position it is shown in Fig. 3 to the position it is shown in Fig. 7. By thus moving the collar, which acts against the hub of the disk V the said disk is forced against the disk U, and in this manner the desired connection is effected.

\Ve should mention here that the surface of the recessed disk V is provided with a pa per lining, o, pressed into it, as indicated, and it required, otherwise secured to the said disk.

A paper lining of this kind constitutes an admirable frictiolrsui'face, and when worn can readily be replaced' \Vhat we claim as our invention is 1.
