April 28, 1931- J. H. HOLE ET AL 0 TAP FOR DISPENSING LIQUIDS Filed Oct. 1 192 INVEHTOR JOSEPH HENRY HOLE WILFRED ROBERT sRYnrqT PER ATTORNEYS.

Patented Apr. 28, 1931 narra- BATET Fries JOSEPH HENRY HOLE AND WILFR-ED ROBERT BRYANT, OF TAUNTON, ENGLAND TAP non n'rsennsnvemenrns Application filed October 1, 1928; Serial No. 309,428, and in Great Britain July 18, 1928.

tionally in the delivering position. A further object of our invention is to obviate lossof liquid due to leakage of the tap and to provide a tap which-is readily operated.

According to our invention the tap consists of a tubular body adapted'to be attached to the desired vessel adaptor orelsewheraand having its free end engaged by a springloaded closure member adaptedto be moved against the influence of the spring ldad to open said free endand to also open a discharge outlet in a sleeve *slidably dispo'sedabout said tubular body.

Simple arrangements of leversare adapted to move the spring loaded closure member against the'infiuence of the spring, the'said levers being so l'oc ate'dand pivoted that a small rocking movement will besuflicient to open *the tap and permit "the free flow of liquid.

In'order that our inventionmay be readily understood and carried into efiect, We append hereto a sheet of'drawings illustrating various embodiments and in which,

' Fig. 1 is apart sectional elevation of a tap constructed according to our invention.

Fig. 2 is afront endview of'Fig; 1.

Fig. '3 is an elevation of a modification showing an alternative arrangement of operating lever.

Fig. 4 is a front end view of Fig. 8.

Fig. shows an arrangement in'which the closure spring is arranged outside the body ofthe tap, this arrangement being particu-- larly useful when used for corrosive liquids.

Fig. 6 is a sectional view taken on line 8-8 of Fig. 5.. i v l Referring to Figs. 1 and 2, the tap which maybe made of any suitable metal or alloy consists of a tubular body rammed at one "end 2 and provided with suitable nuts and washers 3 and 4 for attachment to the appropriate'bung'hole adaptoror other part of the container 620. to be'tapped. The outer end of the tube 1 is machined externally at 5 to provide a nice cylindrical surface. Fixed to the outer end of this tubular body is a collet 6 between the inner edge 7 of which and the inner edge 8 of a further collet 9 slidable on the tube 1 is a strong coiled compression spring 10.

The slidable collet 9 is fixed inside the inner end of a sleeve 11 concentrically disposed about the said tube and closed at its end by a cap 12 which carries on its inner face a washer 13 composed of a material which will resist the action of the liquid being dispensed and abutting against the machined and if desired bevelled outer edge 14 of the fixed collet 6 thereby under the influence of the said spring sealing the end of the tube.

The slidable sleeve has near its outer end an aperture 15 in its lower side this aperture normally being covered by the fixed collet 6. When it is desired to dispense liquid this aperture is uncovered by sliding the sleeve outwards against the influence of the said spring and this action also moves the cap of the sleeve away from the outer end of the tube with the result that the liquid will flow through the outer end of the tube into the sleeve and out through said aperture.

The opening movement of the sleeve can be effected by a lever 16 in the form of two symmetrical arms 16a pivoted at one end to a common bracket 17 and fulcrumed on a common axis 18 to the slidable collet, the other ends of the arms being bridged by a horizontal handle 19. To open the tap the operator places the palm of a hand against the cap at the front end of the sleeve and engages the said handle with the fingers. A gripping action will now compress the spring and open the said aperture. The tap is closed by merely releasing the handle.

The bracket to which the lever is connected can be a ring secured by a nut 20 or otherwise about the threaded part of the tube and having a depending L shaped lug 21 to receive the two arms constituting said lever.

In another arrangement shown in Figs. 3 and 4:, each of said arms can be L shaped, as at 22, the corner of each arm being fulcrumed at :3 to the liding sleeve ll and he o t-er end of the shorter limb 24 of each arm being pivoted to said L shaped lug of the said bracket. The free ends of the other limbs extend slightly beyond said cap 12 and are bridged by a handle 19 which is also adapted to be engaged by the finger of a hand for opening the tap, the thumb of the hand being pressed against a thumb rest 26 extending horizontally beyond and attached to said A further modification is illustrated in Figs. 5 and 6 showing a construction which is particularly useful for corrosive fluids and in this arrangement the spring 10 is shown to be out of contact with the liquid and surrounding the outer circumference of the sleeve 11 being interposed between a collet 39, secured to the said sleeve and a collet which is a sliding fit on sleeve 11 and secured by two diametrically opposite rods 41 attached to the bracket 17 The rods 41 pass through lugs 42 on the collet 89, these lugs also serving as pivots for the levers 16. It will be seen that by placing the palm of the hand upon the cap 12 and grasping the lever 16 between the fingers that the sleeve 11 with its collet 39 may be moved to overcome the pressure of the spring 10 and allow the opening of the outlet aperture.

What we claim is 1. In a tap'of the type described a washer faced sleeve like body slidable on and adapted to abut against the outlet end of a tube adapted to be inserted at its other end into a liquid container or a source of liquid supply, the washer normally sealing such outlet end of the tube and being mounted in one end of said sleeve like body, a coiled compression spring arranged between abutments carried by the tube and sleeve and normally pressing said washer upon the outlet end of the tube, and a hand lever pivotally c011- nected to the sleeve and to the tube for moving said washer from the outlet end of said tube, the said outlet end of the said tube delivering into said sleeve like body, and an escape port in the side of said sleeve like body normally closed by the side of the outer end portion of said tube.

2. In a tap of the type described a washer faced sleeve like body slidable on and adapted to abut against the outlet end of a tube adapted to be inserted at its other end into a liquid container or a source of liquid supply, the washer normally sealing such outlet end of the-tube and being mounted in one end of said sleeve like body, a coiled compression springvarranged between abutments carried by the tube and sleeve and normally pressing said washer upon the outlet end of the tube, and a hand lever pivotally connected to the sleeve and to the tube for moving'said washer from the outlet end of said tube, the said outlet end of the said tube delivering into said sleeve like body, and an escape port in the side of said sleeve like body normally closed by the side of the outer end portion of said tube, said spring being arranged inside the said sleeve like body between it and the tube, the pressure of the spring being adapted to be overcome by rocking said lever which is pivoted to a bracket forming a fixed part of the tap.
