Description

aula sata BENJAMIN FRANKLIN EVANS, OF NEWBURYPORT, MASSACHUSETTS.
Letters Patent No. 109,813, dated December 6, 1870.
IMPROVEMENT IN BARREL SAFETY-VALVES OR VENTS.
` The Schedule referred to in these Letters Patent and makngvpart of the same.
To all persons to whom these presents may come:
Be it known that. I, BENJAMIN FRAXKLIN EvAXs, of Newburyport, of 4the county of Essex and State of Massachusetts', have invented a new and useful Barrel Safety-Valve or Vent; and do hereby declare the saine to be fully described in the following specification and represented in the accompanying drawing, of which- Figure 1 is a side elevation;
Figures 2 and 3, opposite end views; and
Figure 4, a longitudinal section of it.
Figure 4 is a side view of its plug.
Figure 6 is a longitudinal section of' the body part of the vent.
The said body A has the forni of a conic frustulu having a male screw, a, out on its outer surface, and also having. acylindrical bore, '1), extending from its lesser end up to a. transverse partition, c.
Above the said partition is a cylindrical chamber, fl, open at top.
rllh'e partition has a hole or passage, c, extending threngh it axially and concentric with the bore b.
Eheim-gerend of the frustuui A is nicked or grooved dianietlieally, as shown at f j, -the grooves being to c operate as escape-passages and to rece-ive a screwdriver, when employed for screwing the body or frusl' tum A into a barrel-head or stave, as the case may require. v
A pin, B,'provided with a cylindrical head or valve, g, to tit into the valve-seat chamber d, extends, through the passage e, into the bore b, and has a long. slot, ic,- made through its shank.
W'hen the safety-vent is screwed into a` barrel containing aliquor from which, by fermentation or other wisc, there may be generated a gas under pressure, which, were it not for the vent,-would be liable to burst Vthe barrel, the pressure of the gas as it may overcome the resistance of the Vspring of the vent, will elevate the valve-pin or plug B within thebody A until the upper end of the slot ofthe shank ofthe plug may rise above the partition c, and the head ont the pin or plug be raised, so that its bottom may rise above those of the nicks ot the body.
The compressed gas will then more or less escape through the nicks, and as a consequence the barrel will be saved from heilig burst.
I claiin the. barrel satety-vent, as composed of the screw-body A, chambered and nicked as set forth, the notched screw D, the spring C, and the headedand slotted plug B, all constructed, arranged, and tojopcrate together, as explained. u
