Description

UNITED STATES PATENT OFFICE.
ALOIS KOLBEN, OF VIENNA, AUSTRIA-HUNGARY.
VALVE AND COCK.
SPECIFICATION forming part of Letters Patent No. 625,838, dated May 23, 1899.
Application illed October 24, 1898. Serial No. 694,489. (No'model.)
To all whom it may concern.'-
Be it known that I, ALoIs KOLBEN, a subject of the Emperor of Austria-Hungary, and a resident of Vienna, Austria-Hungary, have invented a new and useful Improvement in Valves and Cocks, of which the following is a specication.
The closing of valves and cocks has hitherto been accomplished mostly by pressing a lat or arched loaded or unloaded valve-disk against a valve-seat. This method of closing has the disadvantage that owing to the same parts of the valvedisk being continually forced against the valve-seat a looseness in the closing of the valve very soon takes place, especially with high pressure-such as, for example, with water-conducting cocks.
The object of the present invention is to provide a simple and advantageous construction with a view of obviating the evils mentioned.
In Figure l of the drawings, b is a body attached to the valve-stein c and having a depending interiorly-threaded ange b2.- d is a ball-valve, and h is an annulus. Said annulus b has an eXteriorly-threaded flange b3 engaging the threaded flange b2 of the body, and also has a shoulder b4 bearing against the lower end of said flange b2. The purpose of the annulus is to retain the ballvalve orJ in the valve-body and yet permit said ball-valve to freely rotate in all directions. By this arrangement of the movable valveball a perfect seating of the same on the valveseat d is always maintained, thus sparing the latter to the utmost, as owing to the friction caused by the water passing through the valve, which causes the ball to turn and its position to change, a dierent surface of the ball is continually presented to the seating, so that a perfectly even wearing away with a con= tinual perfect tightness of the valve-closing is brought about.
In Fig. 2 a second form of carrying out the invention is shown. The ball-valve a in this form of construction remains free, thus lying upon valve-seat d without a casing. The pressing of the valve upon the valve-seat is in this form eected by a piston b, which is movably fastened on the spindle c, whereby it may be screwed down onto the ball. On the raising of this piston the valve-'ball is set free and the water lifts it automatically 0E the valve-seat.
Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-
The herein-described valve comprising the casing containing a valve-seat, a reciprocatory valve-stem arranged in the casing, the valve-body b connected to the lower end of the stem and having the concavity in its under side and also having the depending interiorly-threaded flange, the ball a adapted to bear on the valve-seat, and the ball-retaining annulus b having the eXteriorly-threaded flange engaging the interiorly-threaded flange of the body andthe shoulder bearing against the lower end of said iange of the body, substantially as specified.
In witness whereof I have hereunto signed my name, this lst day of July, 1898, in the presence of two subscribing witnesses.
ALoIs KoLEEN.
