SPECIFICATION forming part of Letters Patent No.271,264, dated January 30, 1883.

Application tiled October 11, 18852.

To all whom it may ,concern Be it known that I, RUSSELL PHILLIPS, ot

Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and .5 useful Improvements in Elevators, of which the following is a specification.

My invention relates to freight and passenger elevators, and to safety attachments for the same, the objects being to lessen the ex- Io pense of running and to increase the safety.

I attain these objects by the mechanism illustrated in the accompanying drawings, in whicli- Figure 1 is a side elevation, showing the I principal parts of my elevator. Fig. 2 is a rear elevation of the same. Fig. 3 shows in side elevation that part of the driving-gear and brake devices that is attached to the elevator-carriage. Fig. 4 is a plan view, showing zo that part ofthe driving-gear that is attached to the elevator-carriage. Figs. 5, 6, .7 are views to illustrate the regulator device for controlling the descent ofthe elevator.

In the drawings, A represents the platform ofthe elevator-carriage.

A A2 A3 A4 is the frame, attached to the under side of the same, which serves as a structure for attaching the operating parts.

B3, Figs. 1 and 2, represents a eounterpoise- 3o weight, which is connected to the four corners -ot the elevator-platform A by means of ropes B B' B B', which pass over pulleys B2 B2.

Attached to the frame of the elevator-carriage is a shaft, F', which extends entirely across the elevator, and has at each end a pinion, F2. (See Figs. 1 and 4.) These pinions F2 engage with vertical ratchets F3, Figs. 1 and 4. t

F is a grooved pulley running on a shaft, F',

4o which is so arranged that it may revolve without turning the shaft F', or when desirable its revolution will cause the shaft F' to revolve. This is effected by a conical clutch device which connects it with the bevel-gear Wheel F5, the said gear-wheel F5 being rigidly attached to the shaftF', so that when the grooved wheel F is in clutch-connection with F5, then the revolution of F will cause a corresponding revolution of the shaft F' and the pinions F2,

5o and cause the same to traverse the vertical ratchets F3, Figs. 1 and 4, which action causes a corresponding movement ofthe elevatorcar (N0 model.)

riage. The grooved wheelF is moved in and out of clutch-connection with the wheel F5 by means of the collar G, Fig. 4, and lever K10,

vpivoted at K11, this lever K1" being operated by an arm, K9, which extends radially from the piston-shaft K6, and operates'in an inclined slot, G2, made in the moving end of the lever K1". (See Fig. 4.) The groove wheel F is 60 caused to revolve by the revolution of the y drive-wheel D,Figs. 1 and 2. This drive-wheel D is supported in suitable housings, as shown by D2 D2, Fig. 1, and may be driven by steam, water, or other power. Its motion is conimunicated to the groove-wheel F by means of the rope D3 D5 D*i DE D9 D1U Dl1 D, which is arranged to pass over the several pulleys, H H' H2 H3 H4 H5, (see Fig. 1,) the part D5 D7 passing round the groovewheel F, so that any l motion of the rope D3 D, Src., will cause the groove-Wheel F to revolve, and it' the said groove-wheel F is in clutch-connection with the shaft F' it will cause the elevator-carriage to ascend.

The drive-Wheel D is provided with an internal gear, Fig. 1which engages with the Rinion D', by which it may be driven.

E E', Fig. l, is a pawl, which, engaging with the teeth of the internal gear, will prevent the So Wheel D from revolving in the wrong direction.

The moving parts already described are specially designed for raisin gthe elevator-carriage, although they may be used, if required, for the purpose of lowering it; but I do not depend on this part of the apparatus for loWeringthe elevator-carriage, as I have designed special appliances for regulating the descent of the elevator-carriage, which I will now proceed to describe. 9o

The beveled-gear wheel F5 drives a piniongear, F5, (see Figs. 3 and 4,) whichis connected by a clutch and shaft, F", to the crank-disk F8, Figs. 3 and 4. This clutch F7 is so arranged that when the elevator-carriage is going up the revolution of the beveled gears F5 Fs will not cause the crank-disk F8 to revolve; but when the carriage is coming down the revolution of the gears F5 FG will cause the crankdisk F8. to revolve. Hence by reguilating the roo velocity of this crank-disk I can regulate the velocity of the descent of the elevator-carriage and make the same perfectly safe. This I accomplish by connecting the crank-disk F3,

il 27L26/1 through the pin L, link L', and pin L2, to the sliding cylinder L3, this cylinder traversing on the piston-rods K6 L4, Fig. 4, said pistonrods K5 L4 having no longitudinal motion. The piston-head within the cylinder L3 is compoundthat is, it consists of two perforated disks L5 K7, the disk L5 being stationary, while the disk K7 may be partially revolved in connection with its rod K5. lution of the disk K7 opens or closes the aperture in the disk L5 in the same manner that an ordinary damper or register operates. Con sequently if the cylinder L3 is filled with oil or any other suitable liq uid the resistance offered to its rapid motion may be regulated by turning the disk K7, which, as already stated, diminishes or enlarges the means of communication from one end of the cylinder to the other. This adjustment of the disk K7 is eiected by the lever K5, Figs. 3 and 4, said lever being connected to the shaft K5, as indicated at Figs. 3 and 4, so that by swinging this lever the shaft K5 and disk K7 are operated. This lever K5 may be also operated by means of the hand-rope K K' K2K3, Fig. 3, which runs the entire length ofthe well-room, being rigidly attached at both ends to stationary parts of the well-room structure, a part of this. rope always being accessible to the occupant of the elevator-carriage. As this rope K K' K2 K3 passes round a pulley, K4, attached to the handlever K5, it is manifest thatif the said rope is pulled it will draw the lever in the direction of the arrow R, Fig. 3, and thus operate all of the parts cinematically connected to it. This lever K5 is held'back by the springs S, Figs. 3 and'4. I

As an additional safety device for regulating the descent of the elevator, I use a frictionbrake, P, Fig. 3, placed Within a recess or sink- ,age turned in the face of the wheel F5, the end of the brake bearing against the circumscribing outer wall, P', of the recess, and is held in contact by the indirect action of the springs S and S'When not drawn out of contact by the movement ofthe lever P3, which is pivoted at P3, Fig. 3, the lever P2 being operated in its turn by a projection at k' formed in the'inner side of the lever K5, so that as the lever K5 is thrown over in the direction of the arrow R its action, through the projection 7c', against the under side of the lever P2 at the point P4 will lift up this end of the lever P2, and thus throw vdown the brake P, connected with its otherend. This partial revov N, Figs. 4 and 7, is a tube for furnishing oil for the cylinder L3. (See Figs. 4 and 7.) This feed-tube N (see Fig. 7) is provided with a closing-cap, N', and with a check-valve, N2, as shown. l claim- Y 1. The combination of the drive-wheel D, rope D3 D5 DG D7 D8 D9 D10 Dll D4, the wheel F, shaft F', and pinions F2 with the elevatorcarriage A and vertical racks F3, all arranged to operate substantially as described, and for the purpose set forth.

2. In an elevator, the combinationof the grooved wheel F, adapted to clutch with the gear-wheel F5, and the shaft F', with the clutchoperating device consisting ofthe collar G, lever K10, slot G3, arm K3, shaft K5, and lever K5, all operating together substantially as described, and for the purpose set forth.

3. In an elevator, the combination of the lever K5 and the parts operated by it with the pull-cord K K K2 K3, all substantially as described, and for the purpose set forth.

4. 1n an elevator', the combination of the gear-wheel F5 F5, clutch-shaft F7, crankdisk F3, link L', and cylinder L3 with the pistonrods K'3 L4 and adjustable piston-disk K7 L5, all' operating together substantially as described, and for tbe purpose set forth.

' 5. The combination of the wheel F, the brake P, and lever P2 with the lever K5, provided with a projection, P, all operating together substantially as described, and for the'purpose set forth. RUSSELL PHILLIPS.
