Description

UNITED STATES PATENT OFFICE.
ARI DAVIS, OF BOSTON, MASSACHUSETTS.
STOP-COCK.
Specification of Letters Patent No. 1,371, dated October 16, 1839.
To all 'whom t may concern:
Be it known that I, ARI DAVIS, of Boston, in the county of Suiolk and State of Massachusetts, machinist, have invented a new and usefulV Improvement in the Construction of Metallic Stop-Cocks, and the same can be used for all purposes to which stopcocks are ever applied; and I hereby de- Clare that the following is a full and exact description of my improvement.
In the drawings hereto annexed, Figure l represents the external appearance of a stop-cock suitable for philosophical experiments. Fig'. 2 is a longitudinal section of the same showing the course of the canal, Sac. Fig. 3 represents the horizontal plan, of the same, having the key or tap removed, which key or tap is shown by Fig. 4L.
By referring to Fig. 2 it will be perceived that the canal of this stop-cock (lettered -cL-) coincides with the longitudinal aXis thereof until it enters the bulbl -Z2, where it turns upward, passing through a leather cushion -cin the head of the key or tap -cZ-, thence downward on the opposite side of the axis oi"l the key or tap -CZ- into the bulb -b-, thence out horizontally, &c.
The key or tap (Fig. 4L) sets in a socket in the bulb and turns upon a pintle tesecured into its head, and which passes directly through the center of said bulb -band is secured upon the underside by a nut -fand washer upon the end of the pintle -e-. A leather cushion -0- is interposed between the key and bulb above described to secure a tight joint and prevent leakage. This cushion has apertures corresponding` to those in the bulb -ZJ- and key cto permit the free passage through it of any fluid or otherwise, which passage it is obvious can only be open when the apertures of the key -rZ- and bulb -bare made to coincide. By turning the key CZ- a quarter around, all communication is entirely cut off.
lWhat I claim as my invention and desire to secure by Letters Patent, is-
The mode of arranging the canal -aby carrying it up, after it reaches the bulb, then into the head of the key, CIM down again (on the opposite side of the axis of the key) into the bulb as herein described.
Boston, October 1st, 1889.
ARI DAVIS.
