ivrrn TA'IES j ATENT JOHN A. LANNERT AND IVILLIAM R. JEAVONS, OF CLEVELAND, OHIO.
VALVE FOR HYDROCARBON-RESERVOIRS.
SPECIFICATION forming part of Letters Patent N 0. 561 ,326, dated June 2, 1896.
Driginal application filed s t be 16, 1891, Serial No. 405,832. Divided and this application filed December 8, 1893. Serial No. 493,101. (No model.)
To all whom it may concern:
Be it known that we, JOHN A. LANNERT and WILLIAM R. JEAvoNs, citizens of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Valves for Hydrocarbon-Burners5 and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which itappertains to make and use the same.
Our invention has reference to valves and reservoirs for liquid hydrocarbons; and our invention consists in a novel arrangement and construction of the several parts whereby the guide for the valve-stem is brought into positive and perfect alinement with the valveseat, thus insuring a perfect seating of the valve and preventing leakage, all in a simple, inexpensive, and positive manner, substantially as shown, and particularly pointed out in the claims.
This invention is a division of our application, Serial No. 405,832, filed September 10, 1891, in which the carbureter is the subjectmatter of invention and which forms no part of the present application and patent.
In the accompanying drawings, Figure 1 is a sectional elevation of a reservoir and of our improved device in operatin g position therein. Fig. 2 is a central sectional elevation of the said device, showing the valve-bracket soldered to an ordinary screw-cap of commerce and detached from said reservoir.
It has been found'in practice that if the valve-stem is not held at a right angle with the valve-seat the valve will be leaking and ineffectual. I
In ordinary valves of this nature the valveseat and supporting-bracket are made of separate pieces, and the proper adjustment of the parts requires a high degree of mechanical skill.
By our method the valve-scat, upright support, and lug for supporting the valve-stem are all formed from one piece of sheet metal by press and die work, which, while being wholly inexpensive, brings the parts into absolute and proper relation to each other to produce the condition of a perfect valve in each instance.
The bracket II is made of sheet metal. Its lower portion is bent atright angles, and in this portion is formed a seat for valve D. The
upper portion of the bracket h is also bent at right angles, the hole therein for supporting the valve-stem 61 being brought into exact alinement with the valve-seat in the lower bent portion.
In making this valve a strip of sheet metal is first blanked out to proper shape. \Vhile still a fiat piece it is put into a proper gage and both the hole for stem 01 punched and the seat for valve D formed by a single operation, which locates these points absolutely alike in every blank. Next the blank is laid as a bridge over a channeled die, the hole at one end and the valve-seat at the other end of the blank engaging with suitable guides to positively and absolutely fix the position of the blank over the channel. A punch which nearly fills the channel now forces the central part of the blank-into the channel, the two ends of the blank being forced up by the edges of the channel to parallel each other at right angles to the body of the blank bring the hole on the one and the valve-seat on the other in perfect alinement. The valve and stem can then be inserted into proper position in the bracket by slightly springing the upper end of the bracket, as shown by dotted lines.
The valve is compact'and light and may be soldered in an ordinary screw-cap of commerce, as shown.
That we claim is 1. In a valve for liquid-reservoirs a bracket forming the valve-seat and support for the valve-stem formed out of a single piece of sheet metal, substantially as described.
2. In a valve for liquid-reservoirs, a single piece of sheet metal bent at one end to form a valve-seat and bent at the opposite end to form a support for the valve-stem, substantially as described.
3. In a valve for liquid-reservoirs, a single piece of sheet metal having a valve-seat at one end and a support for the valve-stem at the other end and bent to bring said seat and said support into alinement, substantially as described.
Witness our hands to the foregoing speci fication this 2d day of December, 1893.
JOHN A. LANNERT. \VILLIAM R. J EAVONS. Witnesses H. T. FISHER, GEORGIA SOHAEFFER.
