` v GM IMPROVZElD INCLINBFLANE ELEVATOR.

To all whom it may concern: i i

-Be it `known that I, THOMAS B. Smox'ro'x, of Wilf liamsbnrg, in `t-he county of Kings, and State otNeiv York, have invented a new and useful 'Improvement in InelinedLvPlane Elevator; and I do hereby declare that the following is a full, clear, and exact description thereof, whichwillienable others skilled in the art to make and use the same reference being had to the accompanyin drawings forming part of this specitication, in whic .i

Figure 1, Sheet I, is a vertical section of my im-l Figure 2, Sheet I, is a detail cross-section of one of the ways and sliding bars of the saine. Figure 3, Sheet I, is a detail side view of one of the scroll-wheels. y

Figure 4, SheetfII, is an nnderfside view of my i1n fproved elevator, part of the frame-work being broken away to show the construction.`

Similar letters ofreference indicate corresponding Darts- 4 y f i for its object to improve the construction of my improved elevator patented November 24, 1868, and numbered 84,385, so as to adapt it for use upon the inclines of railways for carrying cars up and down said inclines; and

It consistsin the construetionand combination of various parts of the apparatus, as hereinafter more fully described.

l i `A represents the frame-work `of theelevatoll, tothe side parts of which the ways B are securely attached. C are bars that slide longitudinally upon the ways are connected.

The upper and lower edges of the ways B are grooved longitudinally, and the slidingr bars C are made with hook flanges, which enter the grooves in the ways B, and thus hold the sliding bars 'iu their` places upon said ways. y

To each of the ways B is pivoted aseries or row of 13, and with which the movable parts of the elevator rollers, D, upon which the spiral `serollot' the scrollwheels E `take hold, so that the elevator-platform may be'raised or lowered by revolving the scroll-wheels E in one or the other direct-ion. p

The scroll-wheels E revolve upon axles, attached in an inclined position to the sliding bars G, `so that the upper sides of the said scroll-wheels E may beinclined inward, as shown in fig. 4, toenable the scroll of said wheels to work properly upon the rollers| D of the `In the rim of -tlle scroll-wheels EI are formed teeth, into which mesh. the teeth of the gear-wheels F, attachedA to the shaft G, so at the said gear-wheels F maybe revolved to operate he scroll-wheels E by revolving said shaft G.

the purpose set forth.

To the shaft G are also attached iianged wheels H, the treads oi' which roll upon the rails I of the track,

which rails' I may be attached to ties laid upon the ground or attached to the frame-work A of the elevator, as circumstances may require.

J is another set of flanged wheels, rolling upon the track I and attached to the axle K, which is connected `with the sliding bars C.

One or more of the flanged wheels -H J have teeth Aformed upon the edges oftheir flanges', which mesh into the teeth of racks formed in or connected vwith the rails I, as shown in Bg. 1.

L is the platform, which is connectedwith and supf ported from the axles Gr K by a frame-work, M, which is so constructed as to support the-said platform L `in a horizontal position while passing up and down the incline.

` vN `is the endless rope or chain, by means of which the apparatus `is raised and lowered.

The endless rope or chain N passes around the pulley or wheel O, attached to one or the other of the axles G K, making one or more turns about said pulley.

The rope or chain N passes around the pulleys I and Q, attached to the shafts R and S, secured, respectively, t-o suitable supports at the upper and lower ends of the incline.

The elevator may be operated by power applied to one or the other ot' the shafts It S, as maybe convenient.

Upon one or more of the wheels E H 'J are formed anges, upon which the shoes of the brakes T may operate. i

The brakes T may be applied by means of levers V, passing up at the sides or ends or through slotsin the platform L, so that they maybe convenientlyoperated by the attendanty or attendants standing upon said platform. f

- The brake or brakes T U should be powerful enough to stop and hold the apparatus `and its load at any point of the incline, should anything get out o f order or break,'or should it be necessary from any other cause to hold the apparatus stationary.

Having thus described my invention,

I claim as new and desire to secure by Letters` 1. The series or rows of rollers D, in combination with `the ways B and sliding bars G with which the movable parts of the elevator are connected, substantially as herein shown and described, and for the purpose set forth.

2. The combination of the hooked ianges of the sliding bars O with the grooved sides of the ways B, substantially as herein shown and described, and for 3. The combination of the flanged Wheels and tracks 5. In combination with the rails I, gear-wheels F, H J with the scroll-wheels E, sliding bars C,m1d ways rollers D, and ways B, the wheels E H J and brakes B, substantially :is herein shown and described, and T U, as and for the purpose set forth. for the purpose set forth. The above specification of my invention signed by 4. The combination of the toothed flanges of the me this 19th day of October, 1869.
