To all, 1.0790711 it rim/y concern:

Be it known that I, WI LLIAM POLAOK, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Container-Pumps; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in container-pumps.

The object of the invention is to provide a pump adapted to be applied to a bottle or other container, whereby the liquid contents of the same may be discharged therefrom into small-neck bottles or receptacles without Wasting or spilling.

Another object is to provide means whereby the quantity of liquid so discharged may be ascertained.

A further object is to provide a pump of this character which will be simple, strong, and durable in construction, eificient in operation, and well adapted to the use for which it is intended.

With these and other objects in view, the invention consists of certain novel features of construction, combination, and arrangement 1 of parts, as will be hereinafter described and claimed.

in the accompanying drawings, Figure 1 is a side view of a bottle, showing the invention applied thereto and the manner of using the Fig. 2 is a vertical sectional view of the same. Fig. 3 is a detail Vertical sectional view of the lower end of the pump-barrel, showing a modified construction of the piston-rod valve and showing the piston-rod and valve in side elevation, the valve being shown open in full lines and closed in dotted lines. Fig. 4: is a similar view of the same, showing the piston-rod and Valve in section; and Fig. 5 is a detail sectional view through the upper 5 end of the bottle-neck, showing the manner of securing the pump in the bottle.

Referring more particularly to the drawings, 1 denotes the pump-barrel, which is here shown as a cylindrical metal tube of such size 3 as to fit within the mouth of abottle or other container. The lower end of the barrel is reduced, as shown at 2, to form a valve-seat 3, upon which is loosely mounted a ball-valve 4. 1n the lower reduced end of the barrel are 5 formed recesses 5 to permit the entrance of liquid to the barrel should said lower end of the same engage the bottom of the bottle.

Near the upper end of the barrel 1 is formed an annular series of air-vents 6. On the other end of the barrel 1 is arranged a cap 7, said cap being provided with an annular series of apertures 8, which are adapted to be brought into and out of alinement with the air-vents 6 in the upper end of said valve to open and close the same. On the upper end of the cap is formed a radially-projccting annular flange 9, which is adapted to rest on and engage the upper end of the bottle, thereby closing the same. In the upper end of the cap is formed a centrally-disposed aperture 10.

Arranged to reciprocate in the pump-barrel 1 is a hollow piston-rod 12, said rod passing through the aperture 10 in the top of the cap. On the lower end of the piston-rod 12 is secured a piston 13, and in said lower end of the rod is formed a valve-seat 14, on which is loosely mounted a ball-valve 15. Said valve 15 is arranged to act in conjunction with the valve 4 in the lower end of the pump-valve, whereby when the piston-rod 12 is rcciprocated in said valve water will be drawn therein on the upstroke of the piston, said water being forced into the hollow piston-rod on the downstroke of the same. A continued reciprocation of said piston-rod causes the liquid to be discharged from the upper end of the piston-rod through a spout 16 provided for this purpose. The upper end of the pistonrod is also provided with a head to facilitate the operation of the same.

If desired, the piston-rod 13 may be provided with a measuring-scale 17, whereby the quantity of liquid forced into said piston-rod and discharged therefrom may be ascertained.

In Figs. 3 and i of the drawings is shown aslightly-modiiied arrangement of the pistonrod valve. In this instance the lower end of the piston-rod is closed and above said closed end is formed an annular series of radiallydisposed apertures 18. above which is secured a piston 19. Through the lower closed end of the piston-rod below the apertures 18 passed a stop-pin 20, and on said lower end of the rod between the piston 19 and the pin 20 is slidably mounted a valve 21. This valve 21 is adapted to cover and uncover the apertures 18 on the up-and-down stroke of the pistonrod, thereby admitting and holding liquid in said rod. This latter form of valve is used in connection with the pump-barrels for small narrow-mouth bottles in which the size of the piston-rod is such as to prohibit the use of a ball-valve, as shown in Figs. 1 and 2 of the drawings.

By the use of a pump constructed as herein shown and described the contents of a bottle or other container may be readily removed and the desired quantities discharged into hottles or receptacles having very narrow mouths withoutdanger of wasting said liquid. In operating the pump the spout 16 is inserted in the mouth or neck of a small bottle or receptacle to be filled, as shown in Fig. l of the drawings, thus preventing the spilling of any of the liquid. The flanged cap on the upper end of the pump-barrel forms a closure for the bottle or container, thus taking the place of a stopper, and by turning said cap slightly in one direction or the other the air-vents 6 will be closed, thus forming practically an air-tight closure for the bottle. In order that the pump-barrel and the ca 7 may be securely held in the bottle, springmetal clips 22 are provided, said clips being provided on their lower ends with eyes or pas-' sages 23, through which is adapted to pass a securing band or wire 24, which is passed around the neck of the bottle immediately below the flanged upper end of the same. The clips 22 when swung upwardly into a locked position will engage the upper surface of the flange 9, thereby clamping the same upon the upper end of the bottle and firmly holding the cap and pump-barrel in place.

From the foregoing description, taken in connection with the accompanyingdrawings, the construction and operation of the inven tion will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle 0r sacrificing any of the advantages of" this invention.

Having thus described my invention, what A bottle or other container, and having at its upper end air-vents, a cap arranged on the upper end of the pum p-barrel to close said airvents and the mouth of the container, means to hold said cap-plate and pump-barrel in place, a valve arranged in the lower end of the latter, a hollow piston-rod arranged to reciprocate in said pump-barrel, a valve adapted to open and close the lower end of said pistonrod and a discharge-spout arranged on the upper end of said rod, substantially as described.

2. A pump of the character described, comprising a bottle or container having a flanged neck, a barrel adapted to be inserted into said bottle or container and having at its upper end air-vents, a flanged, apertured cap arranged on the upper end of said pump-barrel to open and close the air-vents therein and to close the mouth of the container, spring-metal clips secured to the neck of the container and adapted to be engaged with the flange of said cap to hold the same in place, a valve arranged in the lower end of said pump-barrel, a hollow, graduated piston-rod adapted to reciprocate in said barrel, avalve to open and close the inner end of said piston-rod and a dischargespout arranged on the outer end of the same, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
