Application filed February 5, 1921. Serial No. {142,812.
To all 107mm it may concern:
Be it known that l, A DREW Ji oKsoN WEL- states of Amerventedf new and useful Improvements in Pumps, of which thefollowing is a specification.
The object of the invention is to provide a simple and eiliicient pressure pump de signed for automatic action under the impulse of a supply or air under pressure as iv from a suitable condenser or compressor controlledby afloat which is actuable by the liquid contents of the pump cylinder, and the particular object in view is to provide a pump mechanism otthe general type indicated whereinthe parts areso'related as to insure reliability inaction to the end that dependent upon a continuous supply of pressure the water service pipe may be con,- nected directly with the pump cylinder so as to be supplied therefrom as required without the intervention or interposition or a reservoir or elevated tank or the equivalent thereof and with this objectin view the invention consists in a construction and combination of parts oi which a preferred embodiment is shown in the drawing,
wherein i Flgure 1 1s a sectional view of the pump mechanism showing the parts in the positions which they occupy when the tank is supplying ater under air ynressn e, the level of the water being; low in the tank.
Figure 2 is a similar view showing); the relationot the parts when, the level of the water in the tanlrhaving been lowered sutliciently to bringthe float into contact with the lower tappet platehas reversed the positions of the parts to cut oil the supply of air pressure and open the air vent preparatory to the refilling; of the tank.
Figure 3 is a similar view showing the parts in the positions which they occupy when, the tank having: been. refilled, the
float is brought into actuating; contact with,
the upper tappetplate to again reverse the positions of the parts by closing the vent and opening the air pressure valve Figure 4 is a transverse section on the plane indicated by the line 44L ot Figure 1. t Figure 5 is a vertical section on the plane indicated by the line 5-5 of Figure 1.
.sure valve 22.
The mechanism consists essentially of a tank which obviously may be of any desired shape, although preferably cylindrical, and dimensions or capacity, in which 1s'ar-,
rangedthe tappetrod 11 preferably located between water outletpipes 12 'which are openat their lower ends and are united at their upper ends to communicate with" a service pipe 13,.said tappet rod being located betweentheoutlet pipes whichjointly form/a gulde for asfioat 14: disposed ,r or' movement in a path approximating the vertical dimensions of the tankbe'tiveen upper and lower tappetplates or. disks 15 and '16. The tappet rodis guided its reciprocatory movements, when actuated by the contact of the float respectively with the said tappet plates, by guides 17 consisting ofcomplee mental plates terminally engaged with the outlet'pipes 12 and mutually forming acentral bearing for the rod, said plates being held in place bymeans of transverse bolts 18 as shown clearly Figure 4.
Carried by the tappet rod preferably through'the intervention of a cross head .19 are the stems 20 and 21 of pressure and. vent valves 22 and 23 disposed respectively for outwardly and inwardly opening movements with reference to valve seats 2% and 25 arranged in the pressure and vent pipes 26 and 27, the former leading from any suit:v able source of supply such as a condenser or compresser (not shown) while the latter may lead to the atmosphere to permit of the exhaust of air from the interior of the tank as the latter is filledwith water by the action of gravity.-- The servi ee'pipe 13 is' provided. with an outwardly opening valve 28 preterably oi the ball type arranged and adapted to retain in the service pipe any v water which'inay have entered the same from the tanlrto'prevent return of the same. when the pressure upon the service pipe in the tanlris relieved by the closing of the pres- Said pressure and vent valves are suitably guided to insure their proper seating: and may be connected with the cross head 19, as shown in the crrawing, by suitable nuts whereby an effective rela tive adjustment thereof may be attained' During the operation of the apparatus to supply water to theservice pipe subject to the opening of taucetsor outlets thereinas in the use of the water for domestic and like.
purposes the p sure valve should be held in its open or nnseated position while the vent valve should be held seated to prevent the exhaust oi pressure applied to the sur face of the water to cause its discharge through the pipes 153 to-tho service pipe, and in order to retain said valves in their indicated positions there is employed a looking means consisting of ball 28 actuated by a spring 29 of which the pressure may be regulated by an adjusting screw 30, said ball being yieldingly held in position for engagement with a seat 31 in the tappet rod and positioned upon the tappet' rod for such engageinentflwhen the latter is in its elevated position and hence with said pressure and ventvalves respectively in their unseated and seated positions.
lVhen the operation of supplying" water has proceeded to an extent sullicient to permit ofthe contact of the'fioat with the lower tappet plate 16, as shown in Figure 2, the
weight of the float will cause the depression of the plate and hence of the tappet rod, disengaging the seat 81 thereoi trom the locking means and simultaneously seating the pressure valve and unseating the vent valve. The surface of the liquid contents of the tank thereby being relieved of superatmospheric pressure the water in the well in which the tanl't is located, under the influence of gravity will enter the .tanh through the inlet 32 in the bottom of the tank, said inlet being surrounded by a seat 83 provided for the reception of the inlet valve 84 which is arranged in a suitable protecting cage 35, the wall of which is perforated as indicated at 35 to provide ports through which water may enter the tank after having passed over the valve seat Said valve is unseated bv the pressure of the water from without, and which is conveyed to the inlet 32 by means of conductors 36 having upwardly directed terminal arms 37 provided at their upper ends with suitable screened orifices 38.
Inasmuch as the positioning" of the pressure controlling and ventvalves is dependent upon the movement of the float which in,
turn is actuated by theliquid conte'nts oi? the tank, it will be obvious that as long: as pressure is supplied to the pressure pipe 21' the. operation of the meclmnism will be automatic, the refilling thereof beingellected from time to time as thesupnlv therein is exhausted through the service pipe, and the premature movement or reversal in the posh tions of the pressure and vent valves after the refilling of the tank being prevented by the locking means which retains the t-appet rod in its elevated position until positively released by the impulse of the descending; float when the latter comes in contact with the lower tappet pl'agj.
Moreover inasmuc as the construction of the locking means will other an appreciable resistance to the movement of the tappet rod, which resistance may be varied by the adjustment of the tension of the spring which actuates the ball latch there will be an appreciable reduction in the level oi? the water in the tank after the float comes in contact with the lower tappet plate, to impose a gradually increasing proportion of the weight of the float upon the tappet plate and therefore when the latch finally yields to the impulse Of the weight the tappet rod will be moved positively and promptly to such a position as to insure an effective readjustment or reversal in the positions 01" the pressure and vent valves to respectively seat and unseat the same, sothat there may be no waste of the pressure incident to an ineffective seating of said valves and no obstacle to the prompt inflow of the water through the inlet port to refill the tank.
