FREDERICK M. FURBER, OF HAVERHILL, MASSACHUSETTS.

DISPENSING-CAN.

SPECIFICATION forming art of Letters Patent No. 705,336, dated July 22, 1902.

Application filed April 17, 1902.

To all whom it may concern:

Be it known that I, FREDERICK M. FURBER, of Haverhill, county of Essex,and State of Massachusetts, have invented an Improvement in Dispensing-Cans, of which the following description, in connection with the'accompanying drawings, is a specification, like characters on the drawings representinglike parts. h

In shoe-factories it is customary to use benzin or naphtha extensively in cleaning the uppers of shoes and removing cement there'- from, and it has been a common practice to saturate the cleaning sponge or cloth by dipping it into an open dish containing the cleaning liquid. This method of saturating the sponge is objectionable on, account of the highly inflammable nature of benzin or naphtha and consequent danger from fire,and, moreover, much of the liquid is wasted by evaporation and by reason of the cleaningsponge being too completely saturated therewith.

The object of my invention is to, provide a tightly-closed can for containing the cleaning liqnid,which is provided with means for expellinga measured quantity thereof,so as to partly saturate a sponge or cleaning-cloth without wasting the liquid. On account of the wellknown characteristics of benzin and naphtha it is impracticable to employ rubber or other packing material in a can for this purpose which would be exposed to the action thereof, and it isalso impracticable to have any'joints in the can below the level of the liquid there in which are not made tight by solder.-

I accomplish the above-named object and fulfil the above-mentioned requirements by producing a can which is tightly closed at the, top and has a reciprocating tubular nozzle which extends vertically through the top of. the can, thelower end of said nozzle being provided with aliquid expelling device which is immersed in the liquid of the can and is provided with an inlet through which the liquid may pass, so that a measured quantity thereof will be contained in said expelling device, which will be expelled when the nozzle is pressed downwardly. I further provide Serial No. 103,835. (No model.)

the discharge end of the nozzle with a plurality of outlets which are adapted to distribute the liquid throughout the sponge when it is pressed upon the nozzle to reciprocate the same and expel the liquid. I further provide a'liquid-receiving cap on the top of said can, which is adapted to collect superfluous liquid not absorbed by the sponge and return the same directly to the can.

.For.a more complete understanding of my invention reference is now made to the accompanying drawings, in which-- ;Figure 1 is a plan View of my device; Fig. 2, a'side' elevation, and Fig. 3 is a central cross-section thereof.

The main body 1 of the can is provided with a screw-threaded neck 2, which is tightly soldered to said body. A cap'3 is threaded to said neck 2, and said cap is provided with a guide-tube 4, which extends therethrough and has a circumferential flange 4 at its upper'end. A liquid-receiving cup 5 is interposed between the top of said cap and said flange 4, said tube passing through a central soldered-to the top of the cap, and the upper side of the flange is soldered at one side to the inner side of the cup. The tube is also soldered at one side to the cap, so that a small passagefi will be provided, which leads from the cup to the can, through which liquid discharged into the cup 5 may flow back into the can. It may be observed that in practice it is simply necessary to leave a small part of these joints unsoldered, as benzin will readilypass through an nnsoldered joint.

A tubular nozzle 7 is arranged in the guidetube 4 and'is adapted to reciprocate freely therein. The upper end of said nozzle is provided with a tip 8, which is threaded into the end of the nozzle, and said tip has a longitu- -vdinal passage into which a, series of slots across the outer end of the tip lead. The

tubular nozzle 8 passes through and has secured to its lower end an annular piston 9, and said piston is arranged within a cylinder 10, said cylinder being in the form of a cup which is closed at the bottom and is provided with a top 10, through which the nozzle 7 aperture in said cap and cup. The cup is passes. Said cylinder is also provided with inlets 11 near its top. A spring 12 is interposed between the top 10 of the cylinder and a pin or collar 13, which is fixed on the nozzle 7, said spring acting normally to hold the piston 9 against the under side of the top 10, and the relative thickness of the piston and the size of the apertures 11 being such that the liquid in the can may readily fiow into the cylinder 10 when the piston is in its normal position. The bottom of the cylinder rests on the bottom of the can, so that when the nozzle is pressed downwardly the spring 12 will be compressed and the piston forced down to the lower end of the cylinder.

The operation of my device is obvious, as the user simply presses a sponge or cleaningcloth down on the protruding end of the nozzle, pressing the 'nozzle and piston down to the dotted position shown in Fig. As soon as the piston passes below the inlets 11 the liquid therein will be confined, so that it will be forcibly expelled through the tubular nozzle 7 and will be discharged through the tip at the upper end thereof. As the sponge will then be pressed down upon the tip of the nozzle, as indicated by dotted lines in Fig. 3, at the time theliquidis discharged therethrough, it will absorb the discharged liquid more or less completely. The slots in the tip of the nozzle provide a seriesof discharge-passages, which cause the liquid to be discharged in different directions into the sponge, greatly increasing the extent of saturation of the latter. If any of the benzin thus discharged should not be absorbed by the sponge, it will fall into the liquid-receiving cup 5 and-will then be conducted back into the tank, so that there will not be any inflammable liquid exposed to the open air for an appreciable length of time, thus avoiding loss by evaporation and danger of fire by the ignition of the escaping fumes. \Vhen the pressure on the top of the nozzle is removed, the spring 12 will return it to its normal position, so that the liquid in the can will again run into the cup or cylinder and fill the same.

It will be seen that the cylinder and piston perform the function of aliquid-expelling device which is adapted to discharge a measured quantity of liquid through the nozzle each time the latter is pressed down to its limit. The size of the cylinder is obviously made to suit ordinary requirements when used as above described.

To fill the can, the liquid may either be poured into the cup 5 or the cap 3 may be unscrewed and the nozzle and cylinder be withdrawn from the can, when the cap and cup are removed, so that the can may be readily filled through its neck.

\Vhen not in use, a cap 14 (shown in Fig. 2) may be placed over the nozzle, said cap fitting over the edges of the flange 4:.

From the foregoing description it will be apparent that I have produced a simple device which overcomes the objections and fills the requirements above referred to.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
