DISPENSING-CAN.

Specification of Letters Patent.

Patented Nov. 2, 19115.

To all whom it may concern:

Be it known that I, FREDERICK M. FURBER, a citizen of the United States, residing at Revere, in the county of Suffolk and State of :Massachusetts, have invented certain Improvements in Dispensing-Cans, 'of which the following description, in connection with the accompanying drawing, is a specification, like reference characters on the drawing indicating like parts.

This invention relates to dispensing cans and more particularly to such cans designed to hold and dispense naphtha, benzin, or other highly volatile liquids.

In the manufacture of boots and shoes it is customary to employ considerable quantities of benzin, naphtha, and the like for cleaning purposes, and as such liquids are highly inflammable and subject to considerable loss through evaporation, it is desirable that dispensing receptacles for such liquids be kept constantly covered and that means to regulate the supply of liquid be provided.

- The object of the present invention is to.

improve and perfect such dispensing cans.

To this end an important feature consists in providing a receptacle which will be economical to construct, simple in operation and durable.

Another feature consists in an arrangement for keeping the contents of the receptacle normally covered while ready for use.

Another feature is an arrangement whereby a small quantity of liquid may be dispensed at one time. I

Another feature is an arrangement whereby any unused liquid may drain back into the receptacle, and a further feature consists in adjustable means to regulate the quantity of liquid dispensed at each application.

In the preferred embodiment of the invention as herein shown, a dispensing can is provided containing a reservoir and a shallow dip pan or brush pan adjacent to the base of the reservoir, to which the liquid in the reservoir is fed by the barometic principle ina well-known manner. A cover for the brush pan is arranged" to be normally in position to close the pan but it is yieldingly sustained so that a slight pressure upon the,

cover acts to displace it, whereby a supply of liquid may be obtained. Adjustable means is provided to regulate the amount of liquid obtainable at each displacement of the cover. An important advantage incident to this construction is that the device is always ready for use and yet the contents are kept constantly covered, thus reducing all chance of evaporation and all danger of fire to a minimum. An additional advantage is that the supply of liquid is regulated without the usual provision ofvalves, no valves or pipe connections being used.

Other important features, details of construction and combinations of parts will be hereinafter more particularly described and claimed.

The accompanying drawing illustrating a preferred embodiment of the invention shows a vertical cross sectional view of the dispensing can.

The numeral 1 designates the main part of the receptacle containing the reservoir and an extension 2 is shaped to form a dip pan to which the liquid from the reservoir flows through a passage 5. The liquid from" the reservoir will flow through the passage 5 and into the dip pan until the level of the liquid rises above the entrance of the passage 5, when further flow is stopped by the action of the air pressure. As the liquid is used up in the dip pan it drops below .the level of the entrance to the passage 5 and the air then forces its way therethrough into the reservoir and the flow of liquid to the dip pan automatically takes place, this being commonly referred to as the barometric feed principle.

In order to fill the reservoir in the part 1 of the receptacle, a round threaded aperture is provided, preferably in the base, in which a correspondingly threaded plug 3 isfitted, having a suitable flange 4 so that a washer 6 of leather, rubber, or the like, may be utilized'if desired to make a tighter joint. By providingthe filling plug in the base, the receptacle is rendered more'nearly airtightthan if such a plug were in the top above the level of the liquid. When the reservoir is to be filled, it is necessary to re verse its position, allowing it to stand on its top portion, and therefore any liquid in the dip pan will be returned to the reservoir,

and the receptacle may be similarly positioned when notlin use to prevent the liquid within the ring 9 which is provided with a slightly projectin flange on its upper part and against this flange the cover 10 is held normally in contact by a spring 14 which may be conveniently set in a central recess 13 in the dip pan and arranged to encircle a lug or boss 16 formed on the central portion of the cover 10. The coverlO also has a raised rim 11 which may be formed integral upon its top surface or be otherwise attached, which rim, by contact with the projecting flange portion of the ring 9 steadies the movement of the cover and serves to more effectually close the dip pan from the air and prevent evaporation. A plurality of holes 15 through the rim 11 are provided as shown. Pressure on the top of the cover 10, as for example by an operator holding a sponge or cloth on the cover and pressing downwardly, moves the cover into the liquid contained in the dip pan, displacing it and allowing it to flow around the edge of the cover 10, through the holes 15 on to the top of the cover where the liquid may be ob-' sorbed by the cloth or sponge. When the pressureis released the spring 14 returns the cover 10 to its normally raised position, and any unused portion of liquid will drain back into the dip pan-through the holes 15.

In order to regulate the depth to which the cover 10 may be depressed and consequently to determine the supply of liquid dispensed with each depression of the cover,

a stud 12 is threaded through the boss16 in the cover 10 and by proper manipulation of said stud the downward movement of the cover 10 is limited by contact of the stud with the bottom of the dip pan. The top of the stud-12 is provided with a slot so that a common screw-driver may be used to rotate it and hence to adjust its position relatively with the cover.

comprising a receptacle having a reservoir, a

. dip pan projecting from one side of said receptacle, a passage affording a barometric feed between sald reservoir and said pan, a

substantially flat cover for said dip pan arranged when slightly depressed to permit the liquid to flow over the top thereof, a

spring in said pan to press said cover in raised position to close the dip pan, said pan having a recess to receive and position said spring, and a ring supported bysaid pan arranged to overlie the margin of said cover and to limit its upward movement.

device of the class described, comprlsing a reservoir to contain liquid, a dip pan arranged to be supplied by liquid from the reservoir by a barometric feed, a vertically movable cover for said dip pan, means for normally holding said cover at the upper limit. of its movement and adjustable means to limit the movement of said cover.

3. A device of the class described, com-- prising areceptacle having a reservoir, a dip pan, a. passage between said reservoir and dip pan, a cover for the dip pan, a spring to hold said cover in raised position, a

flanged ring in the dip pan to limit the upward movement of the cover, and a threaded stud extending through the cover and projecting downwardly to limit the downward movement of the cover.

4. A device of the character described comprising a reservoir, adip pan, a passage afiordmg a barometric feed between said reservoir and sald dip pan, a coyer for said dip pan, resiliently held in raisedposition to affording a barometric feed between said reservoir and said dip pan, a cover for said dip pan, resiliently held in raised position,

and'a flange 5011 said cover having an aper ture therein.

6. A device of the character described, comprising a reservoir, a dip pan having a barometric feed connection with said reservoir, a depressible supply pan acting when in normal position to close the dip pan and constructed and arranged to-permit a small quantity of liquid to flow upon it when depressed, and means-establishing communication between the dip pan and the top of the depressible supply pan to permit any unused portion of liquid to drain back into said'dip pan while said supply pan is returning to normal position.

7 A device of the character described comprising a dip pan, having an open top;

a cover for said dip pan resiliently held in raised position substantially fitting said top, whereby said dip pan is substantially sealed, said cover constructed and arranged to be partially submersible in the fluid contained in the dip pan said cover having .a circumferential raised portion on its upper surface, and havinga passage leading through said raised portion to a portion of said cover which is not in communication with said dip pan except when the cover is depressed.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
