To @ZZ/whom t may concern:
Be it known that I AUeUsrU; Sy'ioLL; a citizen of the United iStates, residingfat Ann Arbor, in the county of llIashten-aw," State of Michigan, have invented certain new and useful Improvements in Spigots; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to new and useful improvements in spigots and particularly to spigots used in connection with barrels, tanks, or the like receptacles containing fluids.
One object of the present invention is to provide a novel and improved spigot which will automatically close whereby leakage and loss of liquid, due to the spigot being carelessly left open, is obviated.
Another object is to provide a novel and improved spigot of this character wherein the iow of liquid therethrough is controlled at two points, thus more eii'ectively sealing the liquid from leakage.
Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.
In the drawing: v
Figure4 1 is a side elevation of a spigot made in accordance with the invention.
Fig. 2 is a vertical longitudinal central sectional view through the spigot.
Fig. 3 is a vertical transverse central sectional view through the spigot.
Fig. f1 is a vertical longitudinal sectional view taken on a line at one side of the median line of the spigot to show one of the side cavities and the closing spring therein, together with the plug carried lug engaging therewith.
Referring particularly to the accompanying drawing, 10 represents the barrel or outer casing of the spigot, one end being tapered and externally threaded at 11 for engagement in the bung hole of a barrel, tank, or other receptacle containing the fluid, while the other end is externally threaded at 12 for the engagement thereon of the centrally apertured cap 13. The tapered end of the casing or barrel of the spigot is closed by the wall 14, in which is formed an opening 15, while the other end is open to receive therein the inner cylinder or plug of Specification. of Letters Iatent.
`Application filed Februaryl'?, 1920.. Serial No. 359,390..l
the, spigot, saidy plug being shown atf 16.`
T-he inner end of 1the cylinder is closed by? 4awa-ll 17 in which* is'fornied van opening 18* for yregistry with tlie'openin'al when tlifey spigot is in open position. he cylinder is hollow and has its outer end closed by a thicker wall 19 into which is secured the stem of the handle 20, said handle being engaged through the central aperture of the cap 13. In one side of the casing there is foi'med the spout 21 with which an opening 22, formed in the side of the cylinder, is adapted to register when the openings 15 and 18 are in register, and through which the liquid passes from the receptacle.
Formed longitudinally in the inner face of the casing, at diametrically opposite points, are the channels or recesses 23, in which are movable the longitudinal ribs 24 formed on'diametrically opposite sides of the cylinder within the casing. In each of the recesses is disposed a longitudinally extending bowed spring 25, the ends of which rest against one wall of the recess while the intermediate portion of the Vspring is engaged by the rib 24.
When the handle is turned in one direction, the cylinder will be rotated to register the openings 15 and 18, and register the opening 22 with the spout 21. In this position the ribs of the cylinder will flatten out the springs, thus placing them under tension so that when the handle is released, the
springs will resume their normal conditions,
trolled at two points, one at the receptacle end of the spigot, and the other at the spout.
. l/Vhat is claimed is:
1. A spigot including a casing having an inlet and an outlet, a turning plug in the casing and having an inlet and an outlet for simultaneous register with the inlet and outlet of the casing, and means between the turning plug and the casing for rotating the turning plug to yieldably hold the turning plug in such position that the inlets and outlets remain out of register.
2. A spigot including a casing having an inlet and an outlet, a hollow member rotatable within the casing.. and having an inlet and an outlet for register with the corresponding kopenings of the casing at times,
the inner walls of the casing having recesses,. the hollow member having longitudinal ribs,f and resilient members in the recesses and .l y engageable between the walls of the recesses 'movable in the recesses, and longitudinally vextending bowed springs in the recesses.
and the ribs to maintain the hollow member insuch position that the inlets and outlets are out of register. Y
3. A spigot including a casing having an inlet opening in one endfand an outlet opening adjacent the other end7 a hollow cylinder rotatable within the casing and havingan inlet arranged to register, at times, with the rst inlet; and an l, outlet arranged to register, at times, with the first outlet, the inner walls of the casing having longitudinally extending recesses, the opposite sides of the cylinder having longitudinal ribs In testimony whereof I aHiX my signature in the presence of two witnesses.
