THOMAS VOJ TA, OF MOUND OITY, SOUTH DAKOTA.
OIL-CAN.
$PECIFICATION forming part of Letters Patent No. 703,862, dated July 1, 1902.
Application filed November 14, 1901. Serial No, 82,219. (No model.)
To all whom it may concern.-
Be it known that I, THOMAS VOJTA, a citizen of the United States, and a resident of Mound City, in the county of Campbell and State of South Dakota, have invented new and useful Improvements in Oil Cans, of which the following is a full, clear, and exact description.
This invention relates to an oil-can with a certain novel arrangement concerning its valve whereby it is made to forcibly and copiously eject the oil upon the operation of its diaphragm-like bottom.
This specification is a specific description of one form of the invention, while the claims are definitions of the actual scope thereof. 7
Reference is to be had to the accompanying drawing, forming a part of this specification, in which the figure represents a vertical section of the oil-can.
a indicates the body of the can, and b the spout. The body a has a bottom a, of flexible metal, normally dished downward, but capable of being flexed inward to exert pressure on the fluid in the can.
a indicates a false bottom lying just above the bottom a and dividing the can into two compartments. Leading from the bottom compartment through the bottom a are two tubes 0 and cl, the tube 0 passing intothe' spout b and the tube d opening at the top of the body a. At the base of the tube 0 is a valve 0, which opens from the bottom compartment into the tube, and at the base of the tube (1 is a valve d, which opens from the tube into the bottom compartment.
e indicates a nipple removably fastened in the wall of the body a near its top and form inga passage leading into the body. In this nipple is an inwardly-opening valve 6 for the admission of air at atmospheric pressure.
The oil filling thebody a and entering the tube cl passes by the valve d into the bottom compartment belowthe false bottom of. Now should the bottom a. be flexed inward the valve d will seat; but the valve 0 will open and the oil will be forced through the tube cinto and through the spout b. The bottom a returns by its resiliency to its normal position, and upon this action the valve 0' seats itself, while the valve d opens and allows a fresh supply of oil to pass into the bottom compartment by way of the tube (2. As the oil is removed from the body a air takes its place by way of the nipple 6. Upon outward pressure, however, the valve e seats. the can, the nipple 6 should be removed.
Various changes in the form, proportions, and minor details of my invention may be resorted to without departing from the spirit and scope of my invention. Hence I consider myself entitled to all such variations as may lie within the scope of my claims.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. An oil-can, comprising a body having a flexible bottom and provided with a spout, and a false bottom dividing the body into two compartments, a tube leading from the false bottom and projecting into the spout, a valve in the lower part of the tube and opening into the same, a second tube leading from the false bottom and opening into the lower compartment, said tube having its upper end extending into the upper portion of the body, and a downwardly-opening valve in the second tube, as set forth.
2. An oil-can, comprising a body having a .flexiblebottom and provided with a spout and a false bottom dividing the body into two compartments, a tube leading from the false bottom and projecting into the spout,a springpressed valve in the lower portion of the tube and openinginto the same, a second tube leading from the false bottom and having its open upper end extending into the upper portion of the body and adjacent to the first-named tube, and a spring-pressed valve in the lower end of the said second tube and opening into the compartment below the false bottom, as set forth. r
3. An oil-can consisting of a body having a flexible bottom and provided with a spout and a false bottom dividing the body into two compartments, a tube leading from the false bottom and projecting a short distance into the spout of the body, a spring-pressed valve false bottom to the upper portion of the body, name to this specification in the presence of a spring-pressed valve in the lower portion of two subscribing witnesses. the tube and. opening into bottom compartment of the body, and an inwardly-opening THOMAS VOJTA' 5 Valve in the upper portion of the body for the Witnesses:
admission of air, as set forth. FRANK ALEXANDER,
In testimony whereof I have signed my H. O. CHAFFEE.
