Description

UNITED STATES PATENT OFFICE,
JOSEPH M. SPAHN, OF CHICAGO, ILLINOIS.
IMPROVEMENT IN BEER-VENTS.
Specification forming part of Letters Patent No. 160847, dated March 16, 1875; application filed November 10, 1874.
CASE G.
To all whom it may concern:
Be it known that I, J osEPH M. SPAHN, of Chicago, in the county of Cook and State of lllinois, have invented an lmproved Beer- Vent, of which the following is a specification:
The nature of this invention relates to an improvement in automatic beer-vents of that class where a rubber membrane or vah-'e is placed under a hole in a plug inserted in the top of the vent and it consists in making the tube of such a vent of a hollow gimlet-pointed screw, and in providing the vent with handles, wherehy it may be screwed through the bung without previously boring the latter.
Figure 1 is a perspective view. Fig. 2 is a detached and inverted perspective view of the plug and its membrane. Fig. 3 is a vertical section of the vent-inserted in a bung.
In the drawing, A represents the body of the vent, having at its lower end a giinletpointed screw, a, through which a channel is drlled from the top, intersected by a lateral passage near the point. The top of the vent is provided with two arms, b, like a gimlet, by which it may be screwed into and through a hung. In the top of the vent is formed a screw-threaded socket, in which is screwed a plug, B, having a channel drilled through it. The lower end has a flanged neck over which is stretched a thin strap of iidiarubber, c, which will vield under the pressure of the atnosphere whenever a partial vacuum is cre ated within the cask by a withdrawal of a portion of its contents, and thus permit just enough air to enter the cask to cause its contents to.
What I claim as my invcntion is The coinbination of the hollow screw-pointed plug A, provided with the arms b, with the plug B and menbrane c, suhstantially as described.
. J OS. M. SPAHN.
