MILTON L. BAKER, or slur RAFAEL, CALIFORNIA, assmnon 'ro srmmnn 01L courm or cs rromwm, or SAN rmcrsco, CALIFORNIA, A CORPORATION or DELA- WARE LIQUID nIsrnNsEn Application filed September 7, 1929. Serial No. 390,932,
This invention relates to liquid dis ensers and, more especially, to that type liquid dispenser having a pump secured to. the cap of a container so that the pump parts are re- 6 movable and replaceable with the cap.
An object of the invention is the general improvement of liquid dispensers of this t pe.
The invention relates to' liquid dispensers of the type employed, for example, in the lubrication of more or less inaccessible parts of machinery, for example, where the lubricant is to be distributed over extended surfaces as is requisite in the lubricating of the spring leaves of motor vehicles. In lubricating suc inaccessible points as the spring leaves of motor vehicles, it is diflicult to hold the container in a position insuring gravity flow of Up the lubricant from the container and, be-
0 sides, it is generally more convenient and practical to apply the lubricant from below the point that is to be lubricated, thus requiring that the lubricant be pumped from the container.
Accordingly, one of the objects-of this invention is to make provision for applying a lubricant to comparatively inaccessible places regardless ofthe comparative elevations of the source of supply and point of application of the lubricant.
Another very important object ofthe invention is to insure proper support of that portion of the discharge tube that-projects from the cap of the container.
Other objects and advantages will appear in the subjoined detailed description.
The accompanying drawings illustrate the invention. Fi 1 is a view, mainly in section, of a liqui dispenser constructed in accordance with the provisions of this invention, the pump being in place in the container.
Fig. 2 is a reduced view of the pump and the container cap to which it'is secured.
Fig. 3 is an elevation of the container shown in Fig. 1, the neck thereof being shown in section and another cap being shown in place on said neck.
Referring to the drawings, acontainer or 0 can is indicated at 4 and is provided with a neck 5 that may be closed by a cap 6, as in Fig. 3, or by a cap 7, as in- Fig. 1. The dispenser is sold with both of said caps and, when sold, the cap 6 is in place to close the neck.
Connected with the cap 7 is a pump, indicated in general by the character 8 and constructed as follows: A vertical pump barrel 9 is fixed at its upper end to the inner face of thecap 7 and-working in the barrel 9 is a plunger 10 operated by a plunger rod 11 which projects through a small opening 12 in the cap 7. The outer end of'the plunger rod 11 is provided with a knob 13 or other suitable handle by which the plunger rod is reciprocated for operation of the plunger.
Within the barrel 9 is a shoulder 14 which limits upward movement of the plunger 10.
ward motion of the plunger 10 is produced by a coil spring 15 positioned within the barrel 9 between said, plunger and the lower end of the barrel 9, said lower end being formed by a head 16. The head 16 is pro- .vided with a port 17 to communicate the interior of the barrel with the interior of the can 4 and said port is controlled by a ball check valve 18 which, being positioned above the port 17, is adapted to open upwardly and close downwardly.
Communicating with the lower portion of the bore of the barrel 9 adjacent to the valve 18 is an L-shaped discharge tube comprising legs 19, 20 positioned substantially at a right angle to each other. The lower end of the leg 19 is secured to the barrel 9 and said leg projects through a small opening 21 in the cap 7. The tube 19 parallels the barrel 9 and, preferably, is positioned quite close to said barrel.
The leg 20 is the longer of the two legs and it extends substantially at right angles to the longitudinal axis of the container 4. The leg 20 is adequatelysupported from the cap 7 by a stiffening member 22 which, in the present instance, is of tubular construction andencloses a portion of the discharge tube 20. The stifiening member 22, in this instance, is tapered, the larger end being firmly soldered or otherwise secured in any suitable contact with the discharge tube 20, and, in
7 this instance, said smaller end substantially fits around the discharge tube. The stiffening member 22, extending both below and above the discharge tube 20, offers considerable resistance to upward and downward bending of the discharge tube.
Screwed or otherwisesecured to the outer end of the discharge tube 20 is a nozzle 23 provided-with arelatively small discharge orifice 24 so that the liquid dispensed will be ejected from the nozzle in a fine jet.
The invention hereinbefore described operates as follows: The container 4 closedby the cap 6 will be supplied to the customer together with the pump 8 mounted on or secured to the cap 7. The purchaser will remove the cap 6 from the neck of the container and substitute therefor the cap 7. In placing the cap 7- on the neck, he will first insert the barrel 9 in the container and then turn the leg 20 about the neck of the container so as to screw the cap' down. operator applies the nozzle 23. against or adjacent to the part to be lubricated and operates the plunger rod 11 in a manner well understood in the art relating to pumps of this character. Moving the plunger 10 against the pressure of the spring 15 forces liquid from the barrel through the discharge tube 19. The operator then allows the spring 15 to retract the plunger and the valve 18 then opens to admit liquid from the container into the barrel.
To make the cap 7 tight, it is preferable that a gasket 23 be employed.
