VENT FOR GASKS.

Patented Dec. 4, 1883.

UNITED STATES PATENT ()FFICE.

JOSEPH P()ZNANSKI, OFNE\V YORK, N. Y., ASSIGNOR OF ONE-HALF TO HENRY M. HAAR, OF SAME PLACE.

VENT F 0 R CA s K s SPECIFICATION forming part of Letters Patent No. 289,555, dated December 4, 1883.

' Application filed September 13, 1883. (No model.)

To all whom it may concern Be it known that I, Josnrnloznnnsn1, of the city and county of New York, in the State of New York, have invented a new and useful Improvement in Vents for Casks, of which the following is a specification.

I11 order to operate successfully the valve of a beer-vent, while it must be free to open for the admission of air when necessary in drawing the beer from the cask, it must close absolutely tight, when the drawing ceases, else all the gas in a keg will escape after the vent is driven in, and the valve must close thus tightly even when the keg to which the vent is applied is tilted as kegs usually are when drawing beer from them.

The invention consists in novel features of construction and combinations ofparts, hereinafter particularly described, and pointed out in the claims, whereby the desired ends are attained.

In the accompanying drawings, Figure 1 is -a vertical section of my improved vent, and a portion of a cask-stave, wherein it is secured. Fig. 2 is a side view of the vent, also including a portion of the*stave; and Fig. 3 is an inverted plan of the vent, the valve-box and valve being removed.

Similar letters of reference designate corresponding parts in the three figures.

A designates the stave, and B designates the vent-plug or body of the vent inserted therein. It consists of a piece of cast-iron or other material having a laterally-extending branch or arm, B, the outer end of which turns downward, and has screwed upon it a valve-box, G, a packing-ring, a, of rubber or other material being used between the valvebox and the part on which it screws to form a tight joint. tral aperture, b, and a valve-seat, c, surrounding the same on the inner and upper side of the said box.

D designates the valve of the vent, here shown as consisting ofa flat disk seating on the seat 0. ,'ihe valve is provided with a stem, D, which extends downward through the aperture b considerably beyond the valve-box C, and on the projecting portion of this stem The valve-box O has a cen-,

is a nut or collar, d, larger in size than the aperture 1). The projecting portion of the stem D may, if desired, be protected by a guard, E, attached to the valve-box O, as shown in Fig. 1.

When the beer-vents are in use they are commonly inclined from the perpendicular as the kegs or barrels to which they are applied are tilted, and it will be seen that air will be admitted through the aperture b if the valve D is simply canted or raised at one side off 60 its seat without the valve being bodily lifted.

As to cantthe valve will require less suction within the keg or cask than to lift it bodily, it will be seen that the valve will be very sensitive to any diminution of pressure in the keg or cask. In case the valve-seat 0 should become clogged with saccharine or other solid matter, so as to prevent the valve D from closing tightly, the valve may be turned by grasping its stem on the nut or collar d with the fingers, and a new seat formed on the saccharine or solid matter. By providing the stem D with a nut or collar, (2, larger than the aperture 1) the valve is prevented from being lost when the valve-box O is taken off for cleaning or for any other purpose. In order that the valve D shall not close the end of the branch or arm B, when raised against it, I preferably form in the end of the branch or arm a groove, 6, (best shown in Fig. 3,) which affords a clear passage for air, even if the valve be pressed up tightly against the end of said branch or arm.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, with a vent-plug having a laterally-extending branch or arm, of a valve-box containing a valve-seat, applied to the end of said branch or arm, a valve fitted to said seat, and having a stem projecting downward through and beyond the valve-box, so that it may be taken hold of for the purpose of manipulating the valve, and a guard attached to the valve-box, and protecting the projecting stem portion, substantially as herein described.

2. The combination, with the vent-plug B formed with the aperture 1) and valve-seat o, and the disk-valve D, having the stem D projecting through and beyond the aperture 2), and there provided with a nut or collar larger 5 than said aperture to confine the valve to the box, substantially as herein described.

3. The combination, with the vent-plug B and its branch or B, having in the end the groove 6, of the valve-box (l, screwed upon 10 the exterior of the said branch or arm, and

constructed with the apertures 22 and valveseat 0, and the valve D, working between said seat and the grooved end of the branch or arm B, and having a stem, D, projecting through the aperture 1), all substantially as herein described.
