ROBERT DUN BAR, OF BUFFALO, NEW YORK.
ELEVATOR.
SPECIFICATION forming part of Letters Patent No. 254,291, dated February 28, 1882,
Application filed January 20, 1882. (No model.) i
means whereby two elevators may be readily adapted for and used in the same vessel at the same time, one of such elevators being an ordinary elevator having the usual vertical adjustment only and the other having a similar vertical adjustment, combined with a suitable means for easily adjusting it and its connections horizontally, thereby adapting it to be adjusted to and used in connection with another elevator in any vessel at the same time, as will be more clearly hereinafter shown by reference to the drawings, in which Figure 1 is a front elevation, showing a portion of an elevator and a suitable mechanism for giving it and its connections both a horizontal and a vertical adjustment, and also a section through several of the doors. Fig.2 is a side elevation of the same. Fig. 3 is a front elevation,'showin g a modified arrangement of my invention; and Fig. 4 represents a side elevation of a portion of the same.
A represents the usual frame-work for supporting an elevator. It passes through the several floors, a a a a and is secured thereto in any well-known way.
A is the elevator-leg, a portion only of which is shown in Fig. 1, Itis supported in a frame, B, arranged so as to -be adjustable vertically up or down on the frame A by means of a series of pulleys, b b, each having a cable, chain, or rope, B, securely fastened to the upper part of the frame-work by a bolt or other wellknown means, B which cables pass under the pulleys b and over the pulleys b, and from thence down to awiuding-drum, 0, (see Figs. 1 and 2,) to which they are securely fastened. The winding-drums c are all rigidly secured to one shaft, 0, so as to be operated simultaneously by a suitable engine, 0, (shown in Fig. 1,) whereby the supporting frame-work B and the elevator A, with its gearing and connections, may be evenly raised or lowered when desired.
Inside of the vertically-adjustable frame B is arranged in horizontal guideways a supplementary supporting-frame, G, which is capable of being moved or adjusted horizontally from either side of the frame A to the other side by means of a screw-shaft, D, having a pulley, D, over which passes an endless cable or its equivalent, D which connects with a pulley, d, on the engine-shaft. The elevator-leg A is hung in this frame 0 so that it is capable of both a horizontal and a vertical adjustment.
The engine 0 and the cables or belts and multaneously by means of the pulleys c c c c and their connecting-cables, chains, or belts, and the engine 0. The pulleys c c and fare arranged in any well-known way so as to be engaged or disengaged to or from the shaft 0 by means of a coupling, f, constructed in the ordinary way.
It will be noticed that the tightening-pulleys or rollers d are supported in a frame, E, and are capable of a vertical movement up or down in the frame E, so they can move sufficiently to allow for or take up the slack in the cables or belts as the elevator-leg is raised or lowered. The frame E moves with the engine. and the other parts while being adjusted horizontally.
In order to render the engine easily adjustablehorizontally,it is fixed in guideways F F, (see Figs. 1 and 2,) which hold it in position and in line during such adjustment. The engine (J operates the elevating mechanism ex clusively, and the engine 0 operates the horizontal and vertical adj ustments of the elevator.
If desired, the pulley b may be dispensed with and the cable B connected directly to some portion of the elevator and then passed over the pulley I); but it would require more power to operate it.
G represents the driving-pulleys on the elevator, and G the driving-pulleys on the engine,which are connected by suitable cables, G (See Fig. 2, also Fig. 1.)
. I claim 1. In an elevator, an engine, (1, and shaft 0, provided with winding-drums c, in combination with the cables B, pulleys b, and tightening-pulleys d, and their connections, for the purpose of giving the vertical adjustment to the elevator, as described.
2. An elevator provided with aframe, A, and a vertically-adjustable supporting-frame, B, and connections, substantially as specified, in combination with a horizontally-adjustable frame, 0, for supporting the elevator and its operating parts, substantially as and for the purposes specified.
3. In an elevator, a supporting-frame, B, provided with a horizontally-adjustable frame, C, for holding the elevator, in combination with the pulleys D d, engine 0, and cable D for giving the horizontal adjustment to the elevator, substantially as and for the purposes specified.
4. In an elevator, a frame, A, vertically-adjustable frame B, and its operating parts, substantially as specified, in combination with the frames E E, tightening-pulleys d, and engine 0 provided with driving-pulleys for connecting by cables with the pulleys G, substantially as and for the purposes set forth.
