Patented Nov. 21, 1933 PORTABLE LIQUID DISPENSER .Bruno W. Seidel, Chicago, 111., assignor to U. 8. Sanitary Specialties Corporation, Chicago, 111., a corporation of Illinois Application January 29, 1932. Serial No. 589,574
3 Claims. (Cl. 221-94) This invention relates to certain improvements in a portable liquid dispenser suitable for use in hospitals, nurseries, etc., for discharge in one operation of a considerable quantity of liquid, such as soap, alcohol, lotion, and the like.
It is an object of the invention to provide a lower actuating means which is in alignment with an upper discharge pipe whereby the liquid may be dispensed and received with one hand; Another object is to provide a dispenser with a pump unit which may be readily removed for inspection or repair. w
A suggestive embodiment of my invention is set forth in the accompanying drawing, in which- Figure 1 is a view in sectional elevation of the dispenser showing the piston in normal retracted position;
Fig. 2 is a fragmentary view in section of the upper end of the container, the section being taken on the line 2 of Fig. 1; and
Fig. 3 is an enlarged fragmentary view in section of the lower end of the container showing the attachment of the tie rods to the base.
Referring to the drawing, the numeral 10 designates a base having adjacent its outer edge an upstanding flange 11 and a depending skirt 12. Seated on the base within the flan e and extending upwardly therefrom is a cylindrical wall 13, the outer end of which is closed by a cover 14 having an annular flange 15 which may be extended over the edge of the wall. The cover is shown as provided centrally with a fill opening 16 and fill cap 17. The base, cylindrical wall and cover constitute a container for the liquid to be dispensed. The container is secured together by tie bolts and base, each of the tie bolts being provided at one end with a head 21 for abutting the cover, the other end being provided with threads for receiving a screw 22. .A gasket 23, such as rubber, or the like, covers the bottom side of the base, the screws 22 extending therethrough to be secured to the tie bolts. To seal the container the space between the wall and flanges 12 and 15 may be filled with a suitable seal 24, such as litharge.
The liquid is dispensed from the container by a pump shown generally at 25, which comprises a cylinder 26 secured as by threaded connection to a head 27, having a flange 28 adapted to be secured to the base. The base is provided with a large central opening 30 through which extends the pump cylinder and head, and is further provided with suitable bosses 31 into which are 20 which extend through the cover the compression of the spring 65. As the piston threaded screws 32 for securing the head to the base against the gasket 23.
Slidably fitted in the cylinder is apiston 35 secured to a piston rod 36 by a cap 37. The piston rod extends through the head which is provided 0 with a suitable packing gland 38'. The end of the piston rod, to which is secured the piston, is provided with an axial bore 39 connecting with a transverse bore 40 below the piston. The piston rod end is beveled at 41 to provide a seat 5 for a ball check valve 42, which is held against displacement by the cap 37. The cap is perforated at 43 to permit the liquid to pass therethrough to the inside of the cylinder as the piston moves downwardly.
A discharge pipe is secured to the end of the cylinder and connects with a suitable spout 61 which is secured to the cover and is located directly above the platform. Preferably, the discharge pipe is removably fitted to the spout so that the pump may be readily removed from the base when necessary.
To operate the dispenser, the platform is depressed by the hand. in which may be held, a receptacle, to move the piston upwardly against is moved upwardly the ball check valve is closed, also the openings 46 and the liquid is forced out of the discharge pipe and spout, and into the receptacle placed on the platform. When the pressure is released from the platform the spring forces the piston to normal position, the cylinder being partly filled with air through the discharge .pipe and partly filled with liquid entering the cylinder through the check valve. When the piston is returned to its position, as shown in Fig. 1, the liquid in the container may flow through the openings 46 and 39 displacing the air in the cylinder.
The device may be provided with a suitable 11o handle 66, such as a bent wire, having its ends pivotally connected to the tie bolt heads.
I claim:
1. A dispenser for liquids comprising a container having a top and bottom removably fitted thereto, a spout supported by the top, a pump within the container supported upon the bottom and removable from the container therewith, and a discharge pipe extending from the pump to the spout having a freely releasable connection with one whereby to render either the top or bottom free for removal from the container.
2. A liquid dispenser comprising a container having at its top a cover and at its bottom a base with an opening therein, a spout secured to the cover, tie rods for securing the cover and base together and to the container, a pump cylinder having a peripheral flange at one end removably secured to the base and closing the opening therein, there being an opening in the walls of the cylinder intermediate its ends, a discharge pipe connecting the cylinder with the spout, a piston in the cylinder adapted to be moved downwardly to a point below the opening therein whereby liquid in the container may flow by gravity through the said opening to fill the cylinder and be forced out through the discharge pipe when the piston is moved upwardly, and means exteriorly of the base and in vertical alignment with the spout for operating the piston;
3. A liquid dispenser comprising a container having at its top a cover and at its bottom a base with an opening therein, a spout secured to the cover, tie rods for securing the cover and base together and to the container, a plate 'removably secured to the base to close the opening therein, a pump cylinder secured to the plate and extendlng upwardly into the container, there being circumferentially spaced openings in the walls of the cylinder intermediate its ends, a discharge pipe connecting the cylinder with the spout, a piston having a valved opening through which liquid in the container may flow by gravity to the interior of the cylinder as the piston is moved downwardly to a point between the circumferentially spaced openings in the cylinder whereupon the liquid in the container may flow directly into the cylinder above the piston to be forced out through the discharge pipe when the piston is moved upwardly, and means exteriorly of the base and in vertical alignment with the spout for operating the piston.
