tacle and Pump, of which the following is a and Fig. 5 is a plan view of the same.

specification.

This invention relates generally to improvements in that class of liquid-receptacles which have combined therewith pumping mechanism for expressing or delivering the liquid without the necessity of tipping the recepta cle.

The invention particularly relates to peculiar constructions or formations whereb, vincreased advantage. is realized in the practi cability and economy ot' construction and inA the utility and convenience of the apparatus to the user.

To these ends the invention consists in the constructions and combinations of parts, all substantially as will hereinafter fully appear, and be set forth in the claims.

The invention, as will be manifest, is of especial utility in tea-kettles. or coffee-pots, oilcans, &c., and lin the accompanying drawings the receptacle is illustrated as in the form of a tea-kettle.

Figure lis a central vertical section of the combined kettle'and pump inclosed therein! Fig. 2 is a horizontal section on line 2 2, Fig. 1.

Fig. 3 is a planview of an upper portion of the kettle adjacent the cover-opening. Fig. 4 is a view similar to Fig.1, but showinga somewhat modified arrangement of some of the parts;

'The kettle or receptacle A has the usual entrance-opening for the liquid, andthe one here shown has,` also, the pouring-spout. B represents an inclosed pump-chamber or subreceptacle set within the main receptacle, which has at its`bottom the valved opening a, the valve being constituted by the ball b, which is seated at the inner orifice of the said opening.

D indicates the piston, which lits and plays fin the inclosed chamber, having the rod or stem d, extended upwardly, and at its upper end provided with' the handle-knob d. The said inclosed chamberB has an`outletopening f, which leads therefrom below the piston` and is upwardly extended in the goose-neck pipe g to the outside of the main vessel. The raising of the piston establishes a suction within the lower part ofv the chamber B, a lifting of the valve and entrance of the liquid into the chamber under the piston, the proper conditions for the suction or vacuum being insured by the provision of the check-Valve, (indicated at h in the outlet-pipe.) The downward forcing of the piston insures a pressure upon the liquid thereunder, closing the valve b and forcing theliquid through the outlet past the then opening check-valve for delivery.

I regard certain of the details of construction in vthis apparatusadvantageous and important, as well` as novel, and will now describe them more in detail.

Referring to the parts constituting th x 7o pump-casing, I provide a casting a; at the bot tom, preferably of malleable iron or brass and of cup shape or annular form, with the bottom closed,- except as to the opening a, and having the downwardly-extending supporting-feet c', whereby the said apertured bottom is held slightly above and away from the'bottom of the main vessel. The said castiugis provided with thelateral hub-openingj for the connection thereat of the outlet-pipe, and `has the upper portion of its circular wall formed with an internal socket or rabbet for the reception of the cylindrical shell which constitutes the side walls of the said chamber. The ballvalve is constrained against undue upward movement and for its return to its seat after having been raised, by the cage constituted by the separated circularly-arranged lugs m m, having the inwardly-deiected extremities, `the deiiection of which maybe imparted for ball has been inclosed. The said lugs are integrally cast as members of said part The said bottom casting of the chamberB has thc radially-extended spring-arms fn; n, which at their inner endsare engaged with the casting and which-are adapted to have their. outer ends in bearing .against the lower side walls of the vessel, maintaining the chamber-casing against lateral displacement so far as v.the lower portion thereof is concerned, while the said chamber-casing has its upper portion restrained against sidewise movement by itting within the internal socket o, which is directly of the cover or is of aseparable element, which is in engagement with the cover p, substantially as shown in Figs. l and 4. The flange surrounding the mouth of the vessel may have one or more angular recesses fu, with which a lug or lugs w of the cover p may engage.

In the construction and arrangement shown in Fig. l the outlet-pipe g is extended upwardly through an opening therefor in the cover p, and on desiring to remove the cover with it is also lifted all of the parts of the pumping device; but in Fig. 4the outlet-pipe is shown as extended through the nozzle of the tea-kettle and the chamber-'casing Iixed against axial movement by the upwardly and outwardly extended spring-arms q q, which bear upon the under side of the annular flange which surrounds the mouth or entrance opening of the vessel. In the latter figure the pump-casing has at its upper end a cap t of inverted-cup form, which has its upper portion projecting through the openingul in the lid, while its outwardly-extended edge flange or lip lies under and in engagement with the portion of the lid bordering its said central opening u, said cap being centrally perforated for the play of the piston-spindle. Under this arrangement the lid may be removed for the purpose of refilling the receptacle without disturbing the pumping devices.

B fitted in said socket, the piston and its operating-rod, the ball-valve b for closing said opening o. and restrained against displacement by said lugs m, and an outlet-pipe connectcd to the said lateral opening and extended to the exterior of the receptacle and provided with a check-valve, all substantially as described and shown.

2. In a receptacle and pump of the character described, in combination, a receptacle having an entrance-opening and a closing lid with an aperture therein, a pump-casing contained in the receptacle, having at its lower portion a valved opening leading thereto from the receptacle-chamber and having its upper extremity extended to terminate just below the lid wi thin said aperture and having thereat an inverted-cup-formed cap, which is centrally apertured and having an outwardly-extended flange which lies under theinner edge portion which surrounds the aperture in said lid, the pump-piston with its rod extended 'through the aperture in said cap above the top of the lid and provided with a handleknob, and the valved outlet-conduit leading from the pump-chamber below the piston to the exterior of the main receptacle, substantiallyas described.

3. In a liquid receptacle and pump of the character described, the combination, with the receptacle having an opening within and through its top and a removable centrallyapertured lid for'said opening, of the pumpcasing centrally set in the receptacle, with the upwardly and outwardly extended springarms q q, which are adapted to lie under the edge portion of the receptacle-top which surrounds the opening, a valved opening in the bottom of the pump-casing, and the valved outlet-opening and conduit leading from near the bottom of the pump-casing to the vexterior of the receptacle, and the piston and rod extended through and above the lid, substantially as and for the purposes set forth.
