" `TQ@ZZ107mm'imu/- @www i i 1.361195 IiQWIl that Il, '101i Sneca Alallii, in the] county of Seneca and` Stdt Dit Nev York; have invented a `new t lSefuljlmitovmnt in Pumps; and I "`1do hereby declare that the following is a` i fi1115i1ea1tandetatdeserptonOfthe Same c fernvlbses hechte the accompanying nWhChi Figur@ 1, l fusies having my improvement, and Fs- '2, @mitm secties ofthe 2111 YQSSQL u Similarletterso ireference indicate cor-` `re,SPQNFIQLIig` Parts l Mboth figures.

e The principal object of this invention is to make` a common single acting liftpuml)l serve not only the ordinary usesfof a wellri l pump, but also as a force pump for throw` ying a constant stream of water to a great i l "Hheight rdistance, for the purposes of eX- tinguishingre, or of `washing windows or vehicles. l v x i `My invention fzconsists` in providing the pump with what"I term'a fventilating air "vessel, whichis `an air vessel applied in the usual waybutufurnished ashereinafter described with ai `screwed cap or some equivalent device by which itmay be readilytventilated to prevent ,the air being confined therein,when theffpump is merelywused for drawing water,`or may be `closed to confine ""theair when it isvdesired to` discharge `the height or distance"Y "\stream. t i e el e l To enable thseskilled in the" art `to make scribeits construction and operation." i

On the wp 0f the air ves- -sel there is a screwed nozzle K, to which is fitted s mit O-r female screwed Cap J Whh `containsja piece a, of india rubber 0r other packing at `the top for closing the top of the nozzle when thenut or cap J, is screwed "dem es Shawn in Fi l, andmakns the air vessel `perfectly atr tight.v Below the packing c, the nutor cap J, has a number sides, which, when it is unscrewed or raised top of the nozzle K, serve to form a free `cornrnunication between the air vessel and surrounding atmosphere. This last -described condition of the air vessel is shown in Figa 2 i l o] make the pump `a common lifting pump, the spout I, has'to bel attached and the nut or cap J, unscrewed as shown in Fig. 2 to ventilate the air' vessel; but to make it a force pump in case of lire, or to throw a constant stream or jet of water to a distance or with force, the spout is taken 0H and the hose substituted, and the nut or cap J, screwed down. Thus it will be seen that the air vessel F, having its discharge at or near the bottom, is convertible with facility and despatch into a simple open water reservoirby slightly turning only the perfo-rated nut or valve arrangement J at the top as represented in Fig.`2 of the drawing, when the valve J being open, the air in the space above the water in the vessel F, having free egress through the perforations b b, is restrainedfrom 'compression during the lift in working the pump which, under this open condition of the air vessel F, acts as the ordi- 1 nary,` well or lift pump in giving an easy falling discharge of the water, which for domestic uses and so forth is generally much more suitable or desirable than a forcible or strong iitful or jerking discharge would be as would take place were the air vessel F kept closed and the air above the water therein" exposed to compression; though culiar or particular domestic use be required, this is quicklyand easily obtained by simply closing the valve J at the top of the air vessel; or another convenient (for some purposes) mode of working may be adopted with equal mouth of the spout I and continuing' to Pump water,

when a prolonged discharge may be `of small perforations or holes ib, b, in its` far enough to raise the packing a, from the i should such a forcible discharge for any pe-v facility, by closingiup with the hand the till the air vessel F be filled with obtained without further pumping by removing the hand .from the mouth of the spout I, and this discharge made slow or quick by opening or closing the Valve J at top, at pleasure. Thus many conveniences are effected by this arrangement, and the facility and rapidity with which the common house or well pump may be converted into a force pump for extinguishing fires and so forth, by screwing down or closing the Valve J and screwing or fitting the hose H on to the discharge as specified and represented in Fig. l, makes the arrangement yet more serviceable.

In no case, it should be observed, is the neck or nozzle K, at the top of the air vessel, meant as a discharge opening for the water; and the valve or perforated nut J fitted thereon is purely an air valve, designed to be opened or closed at pleasure by the hand, to make the air vessel F a close one, or to convert it into a mere open water reservoir, accordingly as the pump is required to work as a common lift one, to produce a free and easy discharge, or as an ordinary forcel pump, `to produce a violent discharge, as specified; and herein exists the difference between this arrangement and the many other Well known forms of pump using a close air vessel sometimes with the discharge pipe penetrating the top and descending into the interior of the air vessel and sometimes with the discharge outlet or spout situated below as specied.

That I claim as new and useful herein, and desire to secure by Letters Patent, is-

The combination and arrangement with the air chamber or vessel F of the pump having its delivery spout or outlet below or at or near the bottom of said chamber sub stantially as shown and described, of a hand air valve, or perforated nut J at or near the top of the air vessel, for the conversion by hand with facility and despatch of the close air vessel into an open water reservoir, or vice versa, above the discharge outlet or spout of the pump; and whereby the uses of the common well or lift pump may be varied with despatch and its conveniences augmented as herein set forth.
