Referring to said drawings, whiclrillusa trate one embodiment of the present invention, the reference character .6 designates a pedestal or stand comprising a hollow base 7 and a hollow post or column 8 rising there:-. froni'upon'the upper end of-which-i's a.jc0n-.

with thevalvearotatablymounte'd discharge v I of ahollow glass glohe or ball, and is pro an enlarged lfraginental central tainerg9 for theliquid soap or'other liquid connnodity' wh ch is to g be d spensed, In the post is secured asleeve 11 which extends through upper and lower cross walls 12 and 13 formed in the fpost; Nuts let are threadedly secured upon the thread-edends of the sleeve 11 and bearaga nst the opposing sides of thewalls "12 and 13, thereby rigidly connecting the sleeve with the post. p p

The container 9 ispre ferably in the form vi-ded .with a downwardly projecting neck 15 "which rests on a cross wall 25 and which is contained within a 'fianged'portion 16 of a collar 17, that isrotatably mounted upon the upper end of the post 8. The upper end of the container hasa filler opening which is iclo sedby a screwjcap 9 provided with a vent aperture for prevent'iifg the container from the flange ofthe collar 17, the container is cemented to the collar with cement 18. On the lowerendfof the collar is a flange 17 which surrounds and encloses the upper end of the-post. Y

Secured'to and moving With the collar 17; -is accylinder "19 which extends partly into thecollar andfpartly into the post '8. A sleeve or bushing 20 secured in the upper end of the p ostfas, for instance, bynieans of screws 21, is provided for receiving the lower end of the cylinder 19 and rotatably supporting the saineand the parts carried thereby on the post. The cylinder 19 rotates in the "sleeve 20 andrests upon'pins. 22 threadedly securedin the sleeve and projecting into a circumferential groove 93 formed in the outer face oi the cylinder 19.,

' The connectionbetween the upper end of the cylinder and the collar, 17 may comprise a cylinder head 24 s eeured to the cylinder and projecting up] through an opening in the cross wall 25 of the collar 17am connected thereto hy agnut 26 threaded upon the upper end ofthe cylinder head and bearing against said cross wall. As sl1own, the cylinder head 24 is formed with a downwardly projecting internally threaded flange 27 which is threa'dedly secured upon the upper end of the cylinder 19, and the upper end portion 28 of the cylinder head is reduced in diameter and is externally threaded for the reception of the nut 26. The construction just de scribed provides means whereby the collar 17 is rotatably mounted upon theupper end of the post 8, but is secured thereon against axial or longitudinal movement with respect thereto. I

In the part 29 of the bore of. the cylinder 19 is a plunger 30 which extends out through the lower open end of the cylinder, at which place the latter is provided with a stuffing box 31, and on the lower end of said plunger is a head or shouldered part 32 against which bears one end of a coiled compression spring 33, the other-end. of which bears against the gland of the stuffing box .31. The force of the spring is exertcdto move the plunger in e a downward direction.

- base and is secured to one arm of lever 37 fulcrumed upon a bracket 38 bolted or otherwise secured to a lug 89 formed upon the inner face of the wall. of the base. arm of the lever engages with the underside of a header enlargement 40 which is provided upon the lower end of a plunger actuating stem 41 that is slidably mounted in the sleeve 11 and projects up to within as-light distance from the lower face of. the head orshouldered part of the plunger, clearance being left be tween the plunger actuating stem and plunger for certain reasons, as will presently appear. It is to be observed that by depressing any of the knobs or heads 35' of the treadles, the stem 41 will be raised and therewith the plung'erwill be moved iupwardly.

Y The cylinder, 19 is formed with the bore 29, as has been explained, and said bore is enlarged in diameter as at 42 near the upper end of the cylinder. Threadedly secured in the wall of the cylinder 19 at the lower end of the enlarged part 42 of the bore is a discharge pipe 43, which extends out through a boss 44 formed on the collar 17, and surrounding said discharge pipe is a sleeve 45 which also extends through the 'boss 44 and is secured therein by set screws 4.6 threaded in the boss and bearing against the sleeve.

On the outer end of the discharge pipe 43 is threadedly secured a discharge tip. 47

L through which the contents are finally discharged. The discharge pipe43, tip 47 and sleeve 45 form a discharge ne'zzle or spout through which the contentsare discharged from the dispensing valve.

Connected to ma-movingwna-um plunger The other 30 is a perforated head or disk 48 which, when the plunger occupies its lowermost position, rests upon the shoulder formed between the enlarged part 42 and reduced part 29 of the bore of the cylinder and closes the dischargev port or passage to. the discharge nozzle, thereby preventing any of the liquid contained in the upper portion of the cylinder from leaking out through the discharge nozzle. By providing clearance between the plunger 30 and stem 41, the head or disk may seat on the shoulder in the cylinder and close the discharge port-to the spout. As shown, the head or disk-48 is connected to the plunger by a rod or other stem 49 threadedly secured in the head 48 and plunger 30.

Threadedly secured in thereduced part 28 of the cylinder head 24 is a bushing 50 having a centrally apertured head 51 on its lower end, and contained in said bushing is a check valve 52 which is arranged to seat upon:- the head 51 and thereby close the ,port or passage therethrough. A pin or stem 53 secured to the upper end of the rod 49 is provided for unseating the valve 5.2 whenever the plunger is moved to the upper end of its stroke, thereby permitting liquid. to flow from the container 9 into the enlarged portion 42 of the bore. of the cylinder from which it may flow out through the discharge spout. The check. valve is held upon its seat by .a coiled I spring which bears against the valve and against av centrally apertured plug 54 which is threadedly securedinthe upper end of the bushing.

In operation, the container 9 is filled with liquid soap or any votherliquid commodity which it :is desired to dispense through the valve. The plunger 30 normally occupies the lowermost position shown in Fig. 1 with the head or disk 48 covering the discharge port to the nozzle or discharge spout. A person wishing to draw some of the contents of the container, depresses one of the treadles 34' thereby raising the plunger '30 and therewith the head or disk 48. As a consequence,

any liquid contained in the cylinder is forcibly discharged through the nozzle immediatelyka fter the head or disk 48 uncovers the discharge port, and when the plunger reaches the upper end of. its stroke. -the pin '53 unseats the check valve 52, thereby permitting the liquid in the container to flow into the cylinder and discharge through the nozzle, and so long as thetreadle is held in its depressed position, the liquid will continue to dischargethrough the nozzle.

\Vhen the treadle is released, the spring 33 forces the plunger 30 down to the lower end of its stroke, thereby returning the treadle to itsnormal positiomand during the down stroke of plunger :1 partial vacuum iscreated in the bore of the cylinder above the an/ii in the lmzzle,whereby any l qu i r si h nozzle i h ve "into the port of the'cylinder above the plunger. "-When the plunger breaches r the lower limit of its stroke, the head or disk 48=closes the porter passage "to the'nozzle. Asthe I receiving cylinderrotatably' mounted thereplungerbegins its down stroke, the pin 53 is withdrawn from the check valve 52, thereby permitting the check valve to seat over the port orpassage in the head 5l of'the bushing 50 and'preventingthe discharge'of any more liquidfromthe container; I;

The collar 17 and parts carried'th'ereby b ing swiveled upon the post, thenozzle'may beiturned to any positionaround'the post, so

' that the contents of the containermay beobt'ained at any place arou'ndthedevice, which -makes it exceedingly handy inasn'1uch as a person need not walk around to any definite place in order to use the" device. For the sake of appearance,"th e post, discharge spout and container maybe polygonal in form, as shown, and may be formed of vitreous enameled metalware. The device is especially adapted for use in hospitals and other institutions and public places.
