CAN OR RECEPTACLE.

SPECIFICATION forming para of Letters Patent No. 325,925, dared september s, 188s.

Application filed March 28,1884. (No model.)

To all whom it may concern:

Be it known that I, MILTON H. GARLAND, of Everett, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Cans or Receptacles, of which the following is a specification.

This invention has for its object to provide improved means for forcing liquid from a can or receptacle by atmospheric pressure, and for drawing back the liquid into the can when desired, and is intended chieiiy for application tooil-cans to supply Oil to lamps.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a vertical central section of a can provided with my improvements. Figs. 2, 3, and 4 represent enlarged sections, showing detalls. Fig. 5 represents a sectional view of a portion of the can and a special arrangement of the discharge-tube.

The same letters of reference indicate the same parts in all the figures.

In the drawings, a represents a can or other vessel adapted to hold oil or other liquid. The top of the can has an inverted dome or depression, a2, provided with an airhole, ai.

To the top of the can, over the depression ai, is affixed a flexible diaphragm, c, of leather or other `suitable material, firmly secured at its edges to the can in any suitable manner, preferably by being clamped tightly between two rings or hoops, 2 2, the outer one of which is pressed into the depression a2 and soldered to the sides thereof or to the top of the can by means-of a flange, 3, bent outwardly from the outer ring 2. The central portion of the diaphragm c has an air-hole, which is provided with a metallic tube or bushing composed of a tube, 4, having a ange, 5, bearing against the under side of the diaphragm, a collar, 6, on the outside of the tube 4, and having a Iiange, 7, bearing on the upper side of the diaphragm, and a nut, 8, screwed onto the threaded upper end of the tube 4, and serving to exert pressure upon the collar 6 and its fiange, and thereby cause the anges 5 7 to tightly clamp the interposed portion of the diaphragm.

gers of the operators hand, and the upper end of its Vcentral orifice, which receives -the tube, is formed to afford a seat, 10, for the operators thumb when it is desired to stop the air-hole of the diaphragm. i

d represents a tube secured to a screw-cap j, which is screwed to a collar, on the `top of the can. Said tube extends ldownwardly nearly to the bottom of the can. d represents an extension of the tube projecting from the The nut Sis provided with ears or handles' '9 9, adapted to furnish a support for two ncan, and preferably bent downwardly at,` its outer end and thus adapted to enter a lamp.

Itwill be seen that when the operator applies his thumb to the seat, 10 over the air-passage and `presses the diaphragm downwardly the air within the can will be compressed and will cause the oil to iow upwardly through the tube d and its extension d into a lamp or other receptacle, the quantity of oil thus forced from the can depending on the extent of the compression of the air.

In a can for supplying lamps I prefer to make4 the diaphragm of such size and ilexibility that a single depression will fill an orvdinary lamp. Should the lamp receive too much oil, the operator can, by uncovering the air-hole Of the diaphragm while the outer end of the tube is immersed inthe oil in the lamp, cause the oil to Siphon back into the can, all the oil in the lamp being capable of removal in this way, if desired. The diaphragm can be easily raised by means of the handles 9 9 when its air-hole is uncovered. If the airhole be stopped while the diaphragmV is being raised the diaphragm will act `to draw the oil back into the can, aswill be readily seen. I prefer to swivel the tube-extension d', so that when the apparatus is not in use it can be turned over the diaphragm and inserted in the air-hole thereof, as shown in Fig. 5, the can being thus sealed so that the contents cannot evaporate nor emit odor. To this end the extension may be inserted in an orifice or socket, i, attached to thecap j, and upset at its lower end, at the lower end of said socket, so that it can rotate freely in the socket. (See Fig. 4L.) The collar 7c surroundsY an orifice through which the can may -be filled when the cap j is remeved.

The inverted dome or depression in the cantop affords room for the depression of the diaphragm, and constitutes a support on which the diaphragm may rest when not in' use. A valve adapted to close automatically when the diaphragm isbcing raised and to open when the diaphragm is depressed may be applied to the inverted dome as a means for maintaining the air-pressure in the can when two or more movements of the diaphragm are required to force out the desired quantity of liquid. When this valve is used, the oil cannot be siphoned or sucked back into the can; but a greater pressure can be secured to expel the fluid.

By making a depression in the top of the can and attaching the diaphragm thereto, making it a part of the can, as it were, and providing a separate filling-orifice into which the dischargespout is secured, I produce a structure Well adapted for the purpose for which it is intended, as it can be emptied and iilled again and again Without disturbing the diaphragm fastenings, and the diaphragm may be forced into the depression for transportation. Y

I claim-.- y

l. A can-head having attached thereto a flexible perforated diaphragm, and having beneath the diaphragm an apertured portion depressed below the plane of the head and capable of receiving the diaphragm when depressed, and having in the remaining portion of the head a discharge-tube extending down- Ward into the can, substantially'as described.

2. A can-head having an apcrtured depressed portion below the plane of the head, a exible perforated diaphragm secured to the head and adapted to be expanded ont of and forced into the depressed portion of the head by means of a suitable handle secured to the apertured diaphragm, and an opening in the can-head provided with a removable discharge-tube extending into the can, substantially as described.

3. The diaphragm having clamping-rings 2 2 at its margin, the outer one of said rings having a iiange, 3, combined with a can or receptacle having a seat or support for the ianged ring, as set forth.

4f. A can or receptacle having a iiexible diaphragm provided WithV an air-hole, and a swiveled discharge-tube adapted to be engaged with the air-,hole of the diaphragm for the purpose of sealing the can, as set forth.

5. The diaphragm having the flanged tube 4, iianged collar G, and nut 8, the latter having handles 9 9 and a thumb seat or bearing, 10, as set forth.

6. The combination, with a vessel having a large perforated depression formed in its top, of a flexible perforated diaphragm secured to the vessel and covering the depression, a viilling-opening in the top at the side of the depression, and a detachable spout or tube iitting said opening, as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing Witnesses, this 24th day of March, 1884.
