UNITED STAT S PATENT OFFICE.
JOHN coins, or llIARQUETTE, MICHIGAN:
HYDRAULIC ELEVATOR.
PECIFICAT ION forming part of Letters Patent No. 376,859, dated January 24, 1888. I f
Application'filed December 9, 1885. Serial No. 185.151. (No modeLl Be it known that I, JOHN CONE, a citizen of the United States,residing at Marquette, in the county of Marquette and State of Michigan, have-invented certain newand useful Improvements in Hydraulic Elevators; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to an improvement in elevators, and belongs to the class of hydraulic elevators operated by means of waterpressurein connection witha cylinder and pisv ton. It is designed moreparticularly for use in cities and towns provided with a watersupply system where a cheap and convenient elevator is required either for freight or passengers; and it consists in certaindetails of construction, hereinafter described, and more specifically pointed out in the accompanying drawings, in which Figure l is a perspective view showing the elevator and its connections; Fig. 2, a side elevation, partly in section.
Generally such elevators have been constructed with the elevator-car resting upon a piston working in a cylinder placed centrally inside of the frame or casing. Again, counterpoise'weights have been used to balance the car and establish an equilibrium between thecolumn of water and thecar. Again, in some instances steam is used to force the wa- In my device I dispense with steam-pressure,.the interior cylinders, counterpoise-weights, and their connecting mechanism, and thus dispense with many items of expense, not only in first construction, but in subsequent repairs. In my device there is but one watercylinder, and this is placed outside of one of the vertical guides.
Referring more particularly to the drawings, the elevator A passes between the guides B, the upper cross-bar being secured to at cable which passes over a pulley secured at the top and at one side of, the guide-frame. This cable passes thence outside of the, frame, and isattached to an exterior piston-rod, E, which enters the water-cylinder F, secured to the outside of one of the guides 13. This rod-E is attached to a piston moving up and down inder.
the cylinder is a water-inlet pipe, G, provided a with a alve, a, and on the opposite side of said cylinder and on line with pipe G, is an exit-pipe,G, provided with a valve, a.
within the watercylinder. Near the top of l The valvesa a are connected to rods H H, which in turn are respectively connected with the upper and lower operating-levers, I J 1 J, by
means of which the rodsand valvesare actuated. At or near the bottom of the cylinder F is an air-pipe, K, which admits air'on the up movement of the piston, and through wqich the air is expelled on the downstroke of the piston.
L represents a safetyeage or guard resting 7 upon the top of. the elevator-frame, and de- V signed to be left in the floor-aperture when the elevator descends. p g
The operation of my device is as follows: Suppose the elevator to be in position for the load on the ground floor, as'shown in Fig. L
The piston will then occupy a position near the top of the cylinder beneaththe inlet-pipe G. The operator thenopens the valve or cock. at from either the upper or lower floor by means of one of the levers connecting with red H, and the pressure of the inflowing water forcesfth'e piston downward and raises the elevator by means of the rope O, the air'in the cylinder beneath the piston being expelled through opening K. Upon rod H,-at a point beneath the upper floor when the cock is open, is a projection or flange, O, with which the elevator comes in contact in its upward course, and by means of which the rod is lifted and the cook a closed,- causing the elevator to au--- "tomaticallystop when level with the floor,
where it is securely held by the pressure of the confined column of water withinthe cyl- 'When it is desired to lower the elevator,' the cocka in the outlet-pipe G is opened in a similar manner from either floori by means of the levers 1 J "and rod H, conwithin the cylinder, caused by weight of the 'necting therewith, and, the pressure of water elevator,being released, it is discharged by the ascending piston until the cock is automatically closed by the descending elevator coming in contact with a projection'or flange, 0, near the bottom of the rodH. As the elevator descends, the guard or cage resting upon the top of the elevator-frame is ,detaiuedin suitable material, but is preferably made of woven wire, thereby combining strength and lightness.
While I have represented an elevator adapted for a single lift of one story, it is obvious that the principle may be applied to buildings of several stories.
It is also obvious that the capacity of the elevator may be regulated by the size of the cylinder and inlet and outlet pipes and its speed by the cocks a a.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
In a hydraulic elevator, the combination, with the main frame, the cage trave ling between vertical guides forming part of the main frame, the rope connecting the cage with the piston-rod, and the pulley over which said rope runs or renders, of the vertical cylinder outside of the guides, the piston, the pistonrod, the air-vent K at the lower end of the cylinder, the outlet and inlet pipes G G, respectively, the valves a and a, in said pipes, the pivoted levers I 1 and J J, and the .connecting rods H H, respectively provided with the arms or tappets O 0, all constructed and arranged substantially as and for the purpose described.
In testimony whereof I afiix my signature in presence of two witnesses.
JOHN GONE.
