APPARATUS FOR ELEVATING LIQUID.

Patented June 4, 1918.

Application filed February 17, 1917. Serial No. 149,240.

To all whoin it may concern:

Be it known that I, JAMES A. MACKENZIE,

aicitizen ofthe United States, residing at Rochester, in the county of Beaver and State of Pennsylvania, have invented certain new and useful Improvements in Apparatus for Elevating Liquid, of which the following is a specification.

My invention consists of an improved apparatus for elevating liquid from a main tank or reservoir and delivering it through a pump-controlled holder into a vending tank or reservoir, at any desired level or any desired location, and has in view to provide means for conveying a practically continuous stream by utilization of atmospheric pressure.

The apparatus comprises a pair of vessels into which the liquid is elevated alternately and from one of which it is delivered while ciated mechanlsm.

One preferred construction is illustrated in the accompanying drawings, in which:

Fig. 2 is a similar vlew 1n side elevation.

Fig. 3 IS an enlarged sectional view of the upper portion of the receiving vessels,

illustrating the float-controlled operating mechanism.

Fig. 4 is a plan view of the construction shown in Fig. 3.

Fig. 5 is a further enlarged sectional detail vview of the float-actuated controlling valve and the surrounding construction.

Fig. 6 is a similar view showing the means for opening the check valve in the feed line to emit return of excess liquid to the main ta I Fig. 7 is a detail .view illustrating the main feed pipe provided with a plurality of branches for collecting liquid of difierent grades from difierent compartments.

In the drawings, A and B represent two independent vessels as tanks which are super-imposed at any convenient location above a main reservoir or tank C, which The apparatus 1 mospheric pressure,

s actuated by normal atoperating to elevate the liquid in a reservoir 0 upwardly through a main pipe 2 through one or the other of

branch connections

3, 3, each having an interpos'ed check valve 4 and leading directly by branch pipe 5 to the bottom of one or the other vessel, A or B.

It is designed that the pipe 5 of each vessel shall be used for both supplying and withdrawal, for, which purpose, by a T- coupling 6, each pipe 5 is provided with a laterally arranged pipe 7 and a check valve 8. These branch connections lead by pipe 9 and coupling 10 to a common outlet or delivery pipe 11, which is provided with an ordinary gl0bevalve 12 for controlling the flow, pipe 11 being provided with any suitable terminal as a hose by which the liquid may be'delivered to any desired point, as a gasolene reservoir of a garage or other dispensing agency.

Each vessel A and B is provided at its central top portion with an upwardly extending cage or conduit, 13, in the lower portion of which is provided a valve seat '14 adapted to receive a vertically adjustable valve 15 to seal the opening through condu-it 13 upon rising of a float 16. Said float has a limited vertical movement and is raised by therising liquid in its vertical reservoir, and is in operative engagement with the suction-controlled valve 15, the float and valve falling by gravity when the li uid is withdrawn.

loat 16 of chamber A alternates in its action with float 16 of chamber B. Each fioat'is adjustably connected with a vertically is mounted with-in a conduit 13 which is in communication with the air exhausting mechanism as hereinafter described.

Valve 15 is secured to the lower end of hollow stem 17 by threaded or other connection and within the stem 17 is mounted the threadedadjusting rod 18. Said rod is provided with a thumb nut terminal 19 at its upper end and extends through the cenmovable hollow stem 17, which stem tubeand its valve are positively actuated by the'rising buoyant movement of float 16 in the particular chamber into which the iqlu-id is being introduced, the float and ve in the other chamber correspondingly lowering upon the emptying of said other chamber.

' justed within the clevis up I provide also for the positive un-seating ofthe valve 15 in the other chamber, as B, when the valve in chamber A is seated, and vice 'versa, by means of a connecting walking beam 23. Said beam is pivotally mounted at 24 on a bracket 25 extending upwardly from the upper portion of the structure and is provided at each end with bifurcated terminals 26. These terminals embrace and engage by means of pivoting studs 27, a clevis 27 which is threaded or otherwise secured to the tube 17, as shown in Fig. 5.

By this means the tube is free to be ador down and in connection with adjusting stem 18, the arts may be exactly set to position and wit relation to the walking beam to effect their desired operation, as will be readily under stood.

It will also be understood that during the exhaustion of the air from one or the other chamber A or B, it is necessary to seal the chamber against entrance of atmospheric air to insure the suction efl'ect of the partial vacuum created within the chamber and for such purpose each chamber is provlded with an air inlet valve cage or casing 28 and a valve seat 29, coiiperating with which is an air inlet valve portion of each chamber.

Valve 30 is connected by stem 31 and link 32 with walking beam 23 by pivot 33, the

30, at the upper connection between the link 32 and valve 30 being loose, as by slot 34. By this means,

when valve 15 is lowered to open the suction conduit to the empty chamber and into which liquid is about to be'introduced, the connection with the atmosphere will be cut oif.

On the contrary, when valve 15 is closed, Sealing the suction, air inlet valve 30 will be simultaneously raised, allowing entrance of atmospheric air and equalizing the pressure to permit the contents of that particular chamber .to flow by avity throu h the one of the conduits 9 to t e polnt of co lection or storage. These two conduits lead into the common outlet conduit 11 as shown in'Figs. 1 and 2.

For the purpose of exhausting the air from each chamber alternately as described,

and creating the desired partial vacuum therein, each casing 13 is insuction communication with an air pump 35 by branch pipes 36 and pipe 37, preferably provided with a vacuum gage 38. Pump 35 is driven by any suitable means, as a belt and pulley 39, and operates to effect continuous exhaust of air by pipes 36 from .one' chamber or the other, alternately.

As stated, supply pipe 2 by branches 3, is

in direct communication through couplings 6 and pipes 5 with the lower end of each chamber A and B, and said pipes 5,.oper ating as inlet and outlet pipes alternately, return the liquid by gravity todelivery pipe 11 through check valve 8, check valve 4 being seated against return of the liquid downwardly through pipe 3. 1

When at any time 1t is desired to return the contents of either chamber A or B'to the main reservoir 0- without delivery through ipe 11, globe-valve 12 is closed and check valve 4 is positively opened'for such return flow. This lation of adjusting stem 40, mounted within the pipe 3 and extending downwardly beoperation is by manipu-,

yond coupling 41 and through a stulfing box and gland 42 thereof and having a thumb nut or other terminal 43.

' The stufiing box and gland may be used to provide suflicient friction for stem 40 to hold it where set, and the stem may be thrust .upwm' d ly tgppen the valve element 4 of check valve 4 to effect such withdrawal. Lowering of stem 40 will leave thecheck valve in its normal condition" of operation When it is desired to use the apparatus for the purpose of delivering quantities of liquid of different kinds, or difi'erent gravity, as in the case of gasolene, the main supply "pipe 2 is provided with a plurality of branch connections 2 each having a controlling globe-valve 2 as clearlyv shown in Fig. 7. By this construction theparticular branch 2 which is in communication with the desired liquid, as in the case of a compartment tank wagon or the like, is opened by valve 2, the other several valves being closed, so that the compartment of the particular liquid desired is thus placed in communication with the machine.
