ELEVATO R.

SPECIFICATION forming part of Letters Patent No. 605,854, dated June 21, 1898.

Application dled August 19, 1896. Serial No. 603,213. (No model.)

To @ZZ whom it may concern,.-

Be it known that I, IVILLIAM CLINE, a citizen of the United States,residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain Improvements in Elevators, of which the following is a specidcation.

This inventionrelates to improvements in that class of elevators in' which the car or platform is elevated through the action of a coun-- terpoise-weight; and the'objects of the improvements are, drst, to raise a car or platform by means of a weight traveling down a hinged track or lever, and, second, to return the traveling weight to its normal position by means of a counterweight, thereby permitting the car or platform to sink to its lower position.

The invention consists in the Vconstruction and combination'of the various parts, as hereinafter fully described, and then pointed out in the claims.

In the accompanying drawings, forming a part of this specidcation ,Figure l is a sectional elevation of a building to -which is applied an elevator embodying my invention. Fig. 2 is a similar view, but showing the parts in the position occupied thereby when the car or platform is raised. Fig. 3 is a view of the elevator from the direction of arrow 3, Fig. l; Fig. 4, a similar viewfrom the direction ofarrow 4, Fig. 2; and Fig. 5, a top plan of the elevator. Fig. b is an enlarged perspective view of the traveler or weight-carriage for elevating the platform. Fig. 7 is a side view of the brake employed by me. Fig. S is a side view l s of a modided construction of the traveler, and

Fig. 9 a vertical section on broken line 9 9 of Fig. 8. Fig. l0 is a horizontal section through broken line l0 10 of Fig. 2.

Similar letters indicate like parts throughout the several views.

Referring to the details of the drawings, A indicatesan elevator-platform located in well A and having its edges within the post A2 A3.

A4 is the ground door of abuilding. A5 indicates'the upper doors, up through'which extends the well A', the posts A2 A3 constituting the framev for the elevator.

AG A7 are the transverse braces of posts A2, and A8 is the ceiling of the upper story.

Parallel with and below transverse braces A5 are drums B and B', journaled in bearings in posts A2 A3, the drums extending outside of the posts on one side of the frame, as shown at b and b. On opposite sides of post A2, adjacent to and below the outward extension of drum B, are upwardly and outwardly extending arms a, to which is hinged the inner end .of a track or lever D, having on its outer end a" loop d. On the lever -D is mounted a weighted traveler E, having flanged wheels e,

Vthat engage rails d', formed 'by the side bars of said lever D.

To each corner of elevator-platform A is a lift-rope F. The upper ends f of two of these ropes are attached to each of the drums B and B and are adapted to be wound around the same to elevate said platform A. Around the outward extensions b and b' of the drums B and B', respectively, are wound ropes g and g', the united ends g2 of which ropes are secured to traveler E. Between drum B and the track-lever D united ropes g and g' pass over a sheave g3, journaled in hangers g4, depending from the ceiling. The ropes g and g' are prevented from working off of the ends of said extensions by rims h and h', respecvthe upper story of the building. To the outer end of the Vtrack-lever D is also attached a hand-rope R, which is carried downward toward post A2 and over a sheave r in an opening r in the upper door A5, through a similar v opening r2 in each of the lower doors, around a sheave t, journaled in hangers beneath the opening in ground door A4, and then around a similar sheave t/ in hangers beneath openings r in the doors on the' side ofjthe elevator opposite that on which the openings r and r2 are located.v Thence the rope R is carried lup through openings r3 and attached to the lower part of weight W. Y

In operating, the car or platform being in its lowered position, strain is exerted on hand- IOO rope R in the direction of arrow l, Fig. l, to depress the outer end of lever D. As said outer end of lever D descends, the traveler E moves down the same, turning drums B and B through ropes g and g, so as to wind up lift-ropes l", whereby the platform A is raised. 1\\"ith the depression of the outer end of track D the weight IV is raised through rope N. To lower platform A, the movement of rope R is reversed, as shown b y arrow 2, Fig. 2, strain being exerted to pull down weight lV, whereby the outer end of track D is raised, loosening ropes g g and permitting lift-ropes to unwind from drums l) D under the strain of platform A. It is to be understood that traveler E is loaded sufficiently to lift the loaded platform. After the impulse iirst given to lever D by the strain eX- erted on hand-rope It the movement of said lever is automatically continued by the action of traveler E, as will readily be understood.

In Fig. 7 is represented a brake which may be attached to any portion of the frame and in position to be applied to either one or both of the drums D 3. This brake comprises a curved spring-arm 5, pivoted at G and having a shoe 7 thereon. The shoe is curved to embrace a portion of the drum against which it is pressed, the vibrating end of the spring being drawn toward the drum to apply the shoe thereto by a hand-rope S.

In Figs. 8 and 0 is shown a modiiication in the construction of the lever and the weighted traveler. In this construction the lever is formed of an upper anda lower plate II', respectively. These plates are suitably connected at their ends, and they are secured in their relative positions by diagonal braces I2. The traveler is provided with flanged wheels 'i both above and below, which engage rails t', formed on the edges of said plates I I. The action of this lever and of the traveler thereon is similar to that of the lever and the traveler iirst described.

The apparatus as shown in the drawings is designed for raising the platform only one story; but the same principle is equally ap plicable to greater elevations.

I do not limit myself to any particular arrangement of the sheaves and drums; neither do I restrict myself to the manner of connecting the various parts herein shown and described, as it is obvious that many changes may be made in the details of the construction without departing from the spirit and scope of my invention.

lla-ving thus described my invention, what l claim as new, and desire to secure by Letters Patent, is-

l. The combination, in an elevator, of a lever, a traveler on the lever, the lever being free to move under the weight of the traveler after a downward impulse is given the free end of said lever, and a connection between the elevator platform or car and the traveler,

2. 'lhe combination, in an elevator, of a lever, a traveler on the lever, a connection between the elevator platform or ear and the traveler, whereby said platform or ear is raised by lowering the free end of the lever, a counterpoise-weight connected willi said end of the lever, and a hand-rope connecting said weight and said free end of the lever, substantially as and for the purpose specilied.

et. The combination, in an elevator, of an elevator platform or ear, parallel drums located above said platform or car,lift-ropes con necting the platform or car and said drums, a lever hinged at the ends adjacent to the drums, a traveler on the lever, the lever being free to move under the weight of the traveler after a downward impulse is given the free end of said lever, and connections between the drums and the traveler, whereby said platform or car is raised by lowering the free end of the lever.

5. rlhe combination, in an elevator, of an elevator platform or car, parallel drums located above opposite sides of said platform or car, lift-ropes connecting the sides of the platform or car with the drums above said sides, a lever hinged at the end adjacent to the drums, a traveler on the lever, the lever being free to move under the weight of the traveler after a downward impulse is given the free end of said lever, a sheave located adjacent to the hinged end of the lever, ropes connecting the drums and the traveler and passing` over said sheave, and means for raising and lowering the free end of'the lever, for the purpose specified.
