ers, of which the following is a specification.

This invention relates to can fillers and has for its object to produce a device of this character for automatically supplying water to a can, into which it is lnserted, until the water attains a predetermined level and then automatically cut 0E such supply of water.

A further object is to reduce a can filler of simple, strong, durab e and'ineXpensive construction embo'dying few parts and no packing requiring frequent or occasional renewal or adjustment With these objects in view and others as hereinafter appear, the invention consists in certain novel andpeculiar features of construction and organizationns hereinafter described and claimed; and in order that it Ina be fully understood reference is to be ha to the accompanying drawing in the line I'I of Fig. 2. Fig. 2,.is a plan view corners of the can and the opposite side on a reduced scale,- and in dotted lines also showing a can receiving the filler. Fig. 3, is an enlarged section on the line III-Hl of Fig. 1.

r In carrying out the invention, a nozzle is employed consisting preferably of an elbow 1, having an enlargement forming a valve chamber 2, which is internally threaded at 3, at its lower end, a casing l, screwed at its upper end into the enlargement so that its upper end shall constitute an upwardlydispos'ed valve sea an upright tube screwed at its upper end into the lower end of the casing, and a casing 6-secured to the lower end of the tube 5, and provided with depending feet 7.

To support the nozzle in a substantially upright position when arranged in a can, hereinafter referred to, it is provided with a skeleton frame consisting of 'a pair of diametrically opposite outwardly bowed rods 8, and a pair of diametrically opposite outwardly-bowed rods 9, the distance be tween the most remote parts of said rods 8 and 9 respectively, corresponding approximately to the-distance between the opposite walls thereof, and the ends oflsaid rods are secured as-shown or in any other suitable manner, in external sockets 1'0, of=the on largement of the elbow, and external sockets of a collar 11 secured on tube 5, at a suitable distance from the lower end. of said tube.

Secured on the tube a short distance above collar 11 is a collar 12, and fitting around the tube and upon said collar is' a cushion,

in the form of a spring 13.

, Fitting slidi-ngly on the tube and normally resting on the cushion 13 is a sleeve 7 14 equipped with a float 15 of spherical form, preferably, as shown. Clamp'cd upon the tube above the float is a collar '16 and pivoted at its lower end to said collar is a link 17, pivotally connected at its upper end to a curved crank -arm 18 projectin, from oneend of a rock shaft 19, arrange horizontally within casing 4 and journaled in sleeve bearings'2O and 21 formed integral with casing 4-. The inner end of bearing 20 is formed withfla tapered seat 22, and the outer end of the bearing sleeve 21 is closed to form apocket containing an expansive coil spring 23, exertingendwise pressure on the rock shaft.

Secured on the rock shaftbetween said bearings is a bifurcated crank arm 21 tapered. at one end to constitute a bearing 25, held in engagement with the seat 22, by thepressure of spring 23, this pressure being augmented when a can is being filled, by the pressure of the water passing downward through the nozzle on the opposite side of the crank arm as will be readily seen by reference to Fig. 3, so that it will be impossible for a leakage of water to occur between the bearing'and its seat 22.

Pivoted on a pin 26 carried by the bifurcated crank arm 2%, is a lift rod 27, for rais ing valve 28 frointhe upwardlydisposed valve-seat hereinbefore mentioned, the valve being preferably formed 'with a centrallydisposed downwardly-opening socket 29 receiving the upper end of the-lift rod.

'The casing 6 is provided with a perforated bottom or spider 30, and secured thereon isa compressible ring 31 forming an upwardly-disposed seat for a reciprocatory valve 32, said valve having a central stem 33 fitting slidingly in the perforated bottom or spider and of length to project a substantial distance below thesame, and the feet 7, when said value 32 is closed. ,It will be apparent that under. ordinary conditions the valve 32 is closed by the force of gravity and that the weight the valve 28 in elevated-position.-

When a can such as indicated by dotted lines 34, is to be charged with water, a flexible hose 35 or its equivalent, is secured on the elbow of the nozzle.

posed substantially as shown in Fig. 2, so as to malntain the nozzle in an upright position. Before the feet 7 engage and arrest v the downward movement of the filler in theother can is to be filled, the

' and it will also be can, the stem of valve 32 comes in contact with the bottom of the can and effects the unseat-ing of said valve. The instant this occurs watereseapes from the tube between the feet 7.

When the water level rises to a predetermined level, the float is raised and in moving upward effects the depression of the lift rod 27 to permit the valve 28 to be forced and held upon its seat by the water in the nozzle above said valve. When anperson in control lifts the filler out of the can, the valve 32 closing under the pressure of the water standing above it in the nozzle, before the gravitative action of the float occurs whereby the reelevation of valve 28 is effected. It will thus be seen that the valve 32 is closed before the'valve 28 is reopened and that the 'partsremain in this position until the valve 32 is again reopened, it being obvious, of course, that it must not be'opened as long as the supply hose is connected to the upper end of the nozzle, except by the bottom of the can being charged with water, noticedthat no shock or jar attends the graviiE-tive action of the float as the downward movement of the latter is cushioned. by the spring 13.

'Fromthe above description it will be apparent that I have produced a can filler possessing the features of advantage enumen ated as desirable and I wishit to be understood thatwhile I have illustrated and de scribed. the preferred embodiment of the in vention I do not wish to be restricted to the exact details of construction shown and described as obvious modiiications will suggest themselves to one skilled in the art.

of the float maintains The filler is then lowered into the can with the frame dis- I claim: 1. In a can ii an internalvalve seat and a pair of alined bearlngs one of which closed to prevent the escape of water therctlnJough, a rock shaft journaled in said bearings and projectingcompletely through one of them, a crank arm secured on said shaft between said bearings and within the nozzle, means for preventing water escaping from the nozzle through the bearing through which the shaft completely projects, a valve in the nozzle for engagement with said seat, a float connected to the said projecting end of the shaft to rock the same, and means movable with the crank arm to unseat the valve when the float moves downward.

2. In a can filler, a, nozzle provided with an internal valve and a pair of alined bearings, one of which is closed. at its outer end, a rock shaft journaled'in said bearings, a crank arm, secured on said shaft between said bearings and within the nozzle, a spring exerting pressure to hold the crank arm with a water tight joint against the inner end of the open bearing, a valve, a float conncctedto the outer end of theshaft to rock the same, and means connected to the crank arm to unseat the valve when the float moves downward.

3. A nozzle embodying a casing having alincd sleeve bearings communicating at their inner ends with the interior of the casing, and one of them opening through the side of the casing at its outer end and the other closed at its outer end; a rock shaft journal'cd in said sleeve bearings, a crank shaft'seeured on said shaft between said bearings, and a spring fitting in the bearing having its outer end closed and exerting pressure against the same and the adjacent end of the shaft to hold the crank arm against the inner end of the other hear- /ing with a watertight relation.

In testimony whereof l ailix my signa 'ture, in the presence of two witnesses.
