F. GOODIER VACUUM'SIPHON PUMP Filed Oct. 28, 1926 ATTORNEY$ Patented June 19, 1923.

VACUUM SIPHON PUMP.
The herein described invention. which relates to a new or improved vacuum'siphon pump has for its object and purpose-a rapid means of emptying the contents of liquid containers, and particularly petrol and parafi'in containers by the rapid and effective exhaustion of the air in the cylindrical barrel of the-appliance partly by automatic and. partly by mechanical means,
thereby permitting the atmospheric pressure to act as the expelling agentin emptying the container of liquid.
In accordance with my invention 1 pro-' vide a cylindrical barrel or chamber open at one end and closed at the top by a cap screwed on or formed as part of the cylinder. Operating through this cap I provide a pump-rod connecting with a. plunger or piston. Entering the cylinder in the upper portion I provide a delivery pipe and feeding into this delivery pipe a small diameter release pipe or vent from a point above the the circumference of the lower-end of the cylinder inlets or apertures which, when the plunger or piston is at its lowest point, af-
ford means for the contents of the container about to be emptied to How into the cylinder, the liquid thus finding the same level inside as outside andin the process expelling an amount of air in the cylinder proportionate to the height of the contents of the container. Owing to the necessity for these apertures being above the plunger or piston they are a certain distance above the bottom of the container which therefore couldnever be com-.
pletely emptied.
To overcome this disadvantage I place a collar round the base of the cylinder, so
formed that while the upper edge-of the collar is in close contact with the outside of the cylinder, there remains a space between the two which forms a continuation of the passage formed by the apertures aforementioned. This construction enables the maximum amount of liquid to be removed from the container.
As the circular edge of this collar might make too close contact with the bottom of the container and thereby restrict the flow of the liquid into the cylinder, I cut away a portion of it in a slanting direction.
I have shown how the liquid to be emptied is utilized to expel a part of the air in the cylinder. Now when the piston or plunger .is raised through the length of the cylinder Further I space around Application filed October 1926, serial No. 1 14,8556, and in the Union of South Africa September 2, 1926.
it carries with it the column of liquid above 1t, more flowing 1n to take its place, until it. reaches the delivery pipe after which I siphoni'c'action is established, but above the plunger or piston would still remain a small cushion of compressed air. To releasethis air and enable the plunger or piston to be drawn quite clear of the. entrance to the delivery pipe I provide a small diameter pipe or vent between the cylinder-top and the delivery branch. By this means the cushion of air is removed and the plunger or piston can be raised to the full height.
Finally I attach to the cap or form-as a part of its conical projection for, use asxa piercer in opening a closed container- By making the diameterof this piercer slightly larger than the collar at the base of the,
cylinder an easy entrance of the pumpv into the container and a su'flicient supply of air to replace the contents is assured.
In order that my inventionmay be readily understood andcarriedinto practice, reference 1s herebymade to the accompanying drawing wherein Fig; 1 is a sectional elevationof the invention, portions being broken away to more clearly illustrate the construc-' 'tion. Figure 2 is a cross-section on line,
Referring to this drawing wherein lllCG II of Fig. 1.
letters of'reference indicate corresponding parts wherever occurring throughout .the figure 0a designates the barrel or chamber to the head of which is suitably atachedi or" maybe formed as part thereof a cap I) recessed to take, a packing gland o ,providedwith wings, lugs, or thelike operating on packing cl which ensures non-leakage around I the pump-rod e. v To the lower end of the pump-rode is attached the piston or plunger f. The
lower end of the barrel or chamber a is encircled by a collar 9 which ism close contact at its upper circumference with the barrel but below that is separated from it by an air-space affording an 'inlet to the liquid which thence finds its way into the barrel I the perforations h the overflow or main delivery pipe is of any air or liquid that may otherwise become compressed above the piston f in the upper portion of the cylindrical barrel a. At-
tached to the delivery pipe is is a clip, screwunion or other convenient means, a length of flexible, tubing 1 which may or may not be provided with. a suitable'turncock as shown at m.
For convenience in maintainingthe in vention in an upright position a clip a is provided for attachment to the wall of the container or for this may be substituted any suitable spring type.
Attached to the cap I) or formed as a part 7 thereof is a piercer 0 whose greatest diameter is somewhat larger than thediameter of the collar g. By its use the container is readily punctured'and a hole" made suffi cieht'ly large'to admit of the easy insertion of the inventionand at the "sametirne to permit adequate supply of air to take the place er the contents as they are removed;
In'operation the container is opened by forcing the point ofthe piei'c' er '0 through the top. The eylindrical' barrel 0 is then inserted and held in positi'on'by the clip or spring n. The purn' '-rod e is then withdrawn to its limit an an instantaneous and coiltihuous fl'owof liquid through the delivery pipe *Z results. Should it be desired to stop the fiowt'emporarily, pushing the pump e downiuntil the pistonor plunger f is 2 below the delivery aperture will efi'eetthe desired result- I This is made possible by the release pipe .In the absence of tliis pip'e a cushion or air would be compressed behind the piston when the latter is jatthe upper limit of its stroke, which cushion would expand when the piston descends to a point below the delivery pipe, breaking the continuity of the liquid column, and interrupting the action. 'offthe siphon. If it is desired to -maintain the siphonic action and yet not slept the container immediately, this can' be e "ec'ted by fitting a suitable tap to the end of the delivery pipe 'Zthroughwhicli the contents canbe drawn ofi as desired;
It will be seen'that I have by my inven-- tion provided a new or improved vacuum siphon pump the use of-which renders it possible to empty containers of liquid using only a single stroke of the pumpirod after which a continuous flow ensues until a maximum quantity is removed, the amount remaining due to drainage from the pump etc. being so small as to be negligible.
The improvements herein set forth are not limited to the precise construction and arrangement herein described, butmay be embodied in various forms and modifications without departing .from the spirit and scope of the invention. a
I claim:
1. A si-phon'pump comprising a cylinder v barrel, a plunger operating in said'bar'rel,
an inlet adjacent 'tlie'low'er end of said" barrel, anoutl-et adjacent tlieup'pe'r end of said barrel; the latter extending above the outlet a suihcient distance to form a recess forreceiving-said plunger, and'an air release conduit; opening into'the barrel above said outlet connecting said recess and said uppermostpoint of said outlet.
2. A siphonpunip comprising a cylinder barrel, a plunger-operating in said barrel an inlet adj acei'it the lower e'ndoii' said barr'el above said plunger when the latter is at the lower limit of its stroke, means forming a conduit externally to said barrel, coin mi'inicat ng w th said outletand extending I substantiallyto the levelof the-bottom of said barrel,"aii outlet adjacent the upper' end of said barrel, the latter extending above the outlet a sufiieient distance to form a recess for're'oeiving said plunger, and an air releasejconduit opens into saidgbai'rel 1 above saidoutle't connecting said recess and said outlet at a point in the latter below the uppermost point of said outlet.
In testimony whereof, I have signer-l my name to this specificatio1i" at Upin gton this tenth day'of September, 1926.: I r FRANK GOODIER.
