WATE R- ELEVATOR.

SPECIFICATION forming To tizi whom t may concern:

Be it known that I, ANDREW J. ENGLISH, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in VVater-Elevators, of which the following is a specification.

My invention relates to an improvement in water-elevators adapted to raise water and force. it through a system of pipes by gravity acting on a descending'v piston the cylinder of which is the reservoir, and is filled by raisingv the weighted piston, which acts as a valve to fill the cylinder.

In water-elevators hitherto employed, when the piston is wound up, an independent wastepipe, to allow the waste above the lower packing and around the piston to run back, is employed. My improvement works a wastevalve in the service-pipe automatically by the movement of the clutch-arm throwing the winding mechanism into and out of gear. Another improvement consists in utilizing the waste-pipe employed as such in winding for the supply-pipe in forcing water, thereby taking water from near the top of the cylindercliamber, instead of at the bottom by an independent pipe, as hitherto used.

Another feature of my improvement conssts in an automatic stop attached to the winding mechanism. A Y

Another feature of my improvement relates to an adjustable top packing, which insures a perfect water-tight upper joint, which is an indispensable requisite in a water-elevator.

' Figure 1 is a central vertical section of my improvement. Fig. 2 is a broken cross-sec tion of myimproved packing. Fig. 8 is a side elevation of my automatic winding stop. Fig. 4o

4 is a detail of the split packing-ring.

A represents a cistern vor well, in which my elevator is suspended. It may be set at any distance above the water, not exceeding twenty-seven feet.

B represents a curb or platform covering the well, to which my elevator is preferably attached by means of boltrods c, secured to crosshead t, which is secured by bolt-rods b b to rods c c, supporting cylinder C. This cylinder may be made of wood or of metal, and suspended in any well-kn own manner. D reppart of Letters Patent VNo. 288,783, dated November 20, 1883.

resents apiston, which is provided with two cup leather packings, el d.

Fig. l shows the ordinary cup-packing secured to the cylinder and piston, and Fig. 2 shows my improved form of packing, which will be hereinafter described. Y

e represents an annular space around piston D, between the cup-valves d d.

E E represent weights, preferably connected by a cross-head, Ff', and attached to piston D.

F represents a rope, one end of which is connected to cross-head b, passing over pulley f on the cross-head E, and around windlass G, for elevating piston D.

g represents a shaft journaled to curb H.

I represents a gear-wheel loosely journaled on shaft g.

J represents a pinion keyed upon crank= shaft K.

L represents a clutch formed on the sleeves` of windlass G and gearsI.

M represents a bell-crank lever pivoted to the curb H, and provided with an arm, m, for sliding gear I in and partly out of meshwith gear J. The arm h of lever M is attached to a cord, '1), which passes around a friction-roller, Z, and is attached to the arm of aweighted lever which is used to open or close the waste cock or valve p, which is attached to wastepipe N, which connects with service-pipes l? and P. The service-pipe P, for conducting the water-supply, enters the upper-portion of the cylinder C, so as to communicate with the annular space c between the cylinder and the piston, and at the upper end of the servicepipe P is a branch pipe, P, for connecting with the system of pipes through which the water is conveyed to the points desired. A check-valve, Q, is arranged in the service-pipe P', and opens upward underl the pressure of the water derived vfrom the weighted piston, said valve closing under the pressure of the water standing in the pipe P when the pis ton descends in the cylinder.

R represents a waste branch val-ve or cock for emptying the service-pipes, to prevent freezing, or for any other cause.

q represents a rod suspended inguide-ears n, attached to curb H. Vhen the weights E and cross-head E are raised to the highest point, cross-head E strikes the lower end c IOO ' bent bell-crank lever n and forces a catch on arm a into the teeth of gears J and I, and arrests the further winding.

My improved upper packing is illustrated in Fig. 2, which is enlarged to show more fully the construction.

o" represents a cap screwed to the cylinder C, which covers the adjusting packing-screws and holds cup-ring d in position.

'U represents a packing-ring suspended on screws s, which tap the same.

t represents holes bored in an annular ilange, a, to admit water into the space to hold the leather d against piston D.

W represents a packing-ring made of suitable material, which acts as a bearing-surface ,for the piston D. Said packing-ring XV is 2o is drawn up against flange u, contracting ring WV around piston D. This form of constructing the packing secures a tight joint and prevents the packing-leather d from dropping away from-the piston, or the water from entering between the packing d and piston D. rlhe annular projecting edge of the cup-packing d', at the lower end of the piston, on its descending movement, does not tightly iit the interior of the cylinder, but provides a space between the edge of the packing and the cylinder, so that the water rises upward through the said space to iill the annular space c, and thence through the service-pipesP P. Vhen the piston is raised against the pressure of the water above the packing d', the edge of the latter is forced outward to bear closely against the interior of the cylinder, whereby a vacuum is created under the piston, the

- lower valve is opened, and the cylinder is filled below the piston.

My device is operated as follows: Fig. l represents gear I in mesh with gear J, for win ding up the weights E and piston D. Valve p is opened, theweight O being raised, so that as. pistonD is elevated the water in space c passes out through pipes P N and drops into the well A. As soon as weights E and crossure is relieved from the check-valve Q by opening a cock in the service-pipe P, allowing the weighted piston D to descend, which will force water upward around the lower cup-ring, d, into space c, from thence through pipe P P into service-pipe P. The closingv of the service-pipe arrests the descent of the weighted piston, and check-valve Q closes, preventing the waste of water from the servicepipe when valve or cock is opened for winding at the piston D."

I claimp l. The combination, in a water-elevator, of the cylinder C, having the packing d at its upper portion, the weighted piston D, having at its lower end a packing, d', the edge-of which projects and is flexible, said cylinder and piston being arranged so as to provide the intervening space, e, and the service-pipe P, leading directly from the upper portion of the intervening space to the system of waterservice pipes, said packing d" on its descent admitting the full water-supply betweeny it and the cylinder into the intervening space and to the service-pipe connected therewith, and on its descent being forced out by the water-pressure above it to closely lit the cylin- 1 der, substantially as described.

2. The combination ofthe piston D and cylinder G, arranged so as to provide the intervening space, e, the water-supply pipe P, connecting with the said-space, the branch pipes P P, and the waste-pipe N, having the weighted Valve p, with means for closing the valve p against the action of its weight, substantially as described.

. 3. The combination of the cylinder C, weighted piston D, a drum, G, and rope for raising the piston, a clutch, L, means for operating the clutch, a service-pipe, P, a valve, p, in the waste-pipe, and means for closing the said valve by the disengagement of the clutch from the winding-drum to permit the weighted piston to descend, substantially as described.

i 4. The combination of a cylinder, C, va piston, D, therein, a weighted cross-head, E', winding-drum G, winding-gears I J, pivoted armn, having a catch to engage the gears, and slide-rod q, substantially as described.

5. In combination with the cylinder and piston D, the adjustable packing-ring fu, split ring NV, and the cup-packing d, substantially as herein set forth.

6. The combination, with the cylinder vC and piston D, of a cup-packing, d, the annu- IOO IIO

lariiange a', having the orifice t, and the adjustf able packing-rings o WV, said orifices serving to admit water over the ring W to press the cup-packing d against the piston, substantially as described.

In testimony whereof I have hereunto set my hand.
