ELEVATOR.
Patented Nov. '7, 1882.

PHILIP HINKLE, OF SAN FRANCISCO, CALIFORNIA.
ELEVATOR.
SPECIFICATION forming part of Letters Patent No. 267,204, dated November 7, 1882.
Application filed October 16, 1882.
To all whom it may concern Be it known that I, PHILIP HINKLE, of the city and county of San Francisco, and State of California, have invented certain Improvements in Elevators; and I hereby declare the following to be afull, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which- Figure l is a view in elevation, illustrating my improvements, the counterpoise-tubes being in section. Fig.2shows myimprovement applied to the exterior of a building, when it may be used in lifting light loads or be used as a fire-escape. Fig. 3 is a vertical sectional enlarged view of the counterpoise or weight.
The object of my invention is to prevent danger in elevators arising from the cage being detached from the hoisting device, be the said hoisting'device a rope or cable or a hydraulic ram; and myinvention consists in combinin g with an elevatorcage and proper cables and pulleys a tube or tubes in which move weights of a less cross-sectional area than the tubes, through a medium more dense than air contained within the said tubes.
My invention further consistsin certain details of construction, as hereinafter fully described and claimed.
In order that those skilled in the art may make and use my invention, I will proceed to describe the manner in which I have carried it out.
In the said drawings, A is an elevator-cage, shown, for purposes of illustration, as hoisted by the cables or ropes a a. Alongside of the well I place one or more tubes, B B, having flaring or funnel-shaped tops I) b and stuffingboxes b 1). Cables having one end attached to the cage at cl pass up over sheaves C C in the frame-work, and thence down through stuffing' boxes bb into tubesB B, and the ends secured by proper means to weights D D, so that as the cage moves down the weights are drawn up, and vice versa. The weights D are cast with heads 6 of a diameter slightly less than the tubes in which they move This variation of diameters maybe more or lessin accordance with rapidity required in the travel of the cage, for the reason that tubes B B are kept consta-ntly filled with oil or water or some medium liquid in the tubes.
(N0 model.)
more dense than air, and as the weights D D travel through the said medium of course they can only travel just as fast as the oil or water can pass between the weightand the tube. In order to facilitate the descent of the weights when the car or cage is being hoisted, and yet retard its rapid descent in case of breakage, I cast the weights D D with a central longitudinal opening, f, through them, and place on top of the weight a trap-valve, g, which tightly closes the opening when the weight is passing up and the cage is descending, but which opens freely as the weight descends, as the load is being hoisted, and allows more speed in the hoisting. The cables or other means for suspending the weights would unavoidably,whenpassing up through the stuffing-boxes, carry out a quantity, more or less, of the oil or other The funnel-shaped ends or tops I) I) catch and retain this withdrawn oil or water, and it is carried back into the tubes when the movement of the suspension-cable is reversed.
When the elevator is of the hydraulic-ram variety the operation and application of my invention should simply be reversed, as the enormous weight used in such elevators is calculated to crush the cage against the upper frametimbersif the cage or car gets loose from the lifting-ram.
It will be obvious that within the limit of safety a great variety of variations may be had as to the rapidity of the travel of the car and the amount of direct effect had on the car by the weights.
In some instances, where only heavy loads are to be lowered, no other devices will be necessary than the tube or tubes B and the contained weights,because the weight or weights may be made so heavy as to carry up the cage with a light load or an attendant, and when at an elevation the cage may be loaded to a full load, but it can only descend just so fast and with perfect safety to the load. This safety is enhanced by a liquid cushion I form at each end of the tubes by slightly contracting their inner diameters, as at n n, so that the weight at each end of the travel is checked by a yielding elastic resistance.
A modification of my invention seen in Fig. 2 shows its adaptation to acheap elevator and fire-escape. The tube is placed on the exterior or other convenient point of the building and the tube filled with liquid. The Weight is so proportioned as to raise the light cage with a boy or other attendant, and any desired'latch or catch may be used to check the cage and hold it at any Window or other poin As long as the sheaves and cable will hold, the cage may be loaded and descend safely.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. An elevator-cage in combination with a counterpoise-weightmoving in a tube containing a liquid, for the purpose specified.
2. The counterpoise for an elevator-cage, provided with a longitudinal opening or open ings closed by a valve when the counterpoisc eczeoa is moved in one direction and opened when it is moved in the other.
3. The tube in combination with a counterpoise having the heads 6 e.
4. The counterpoise-tube B, in combination with the funnel-shaped top A, for the purpose specified. I
5. The counterpoise-tube 13, having its interior diametercontracted at n it near its ends, substantially as set forth.
6. The counterpoise D, in combinationwith the tube containing a liquid, a cage, and a connecting-rope, all constructed arranged, and
