IMPROVEMENT IN COCKS.
The Schedule referred to in thesre Letters Patent and making part of the same.
Ving our improvements.
Figure 2 isa sectional view of the same, showing the inside or packingbox.
To enable others skilled in the art to make and use our invention, We will proceed tc describe its con,` struction and operation.
a is a. boxor chamber.
b is a dange or seat.
c isa collar rmly secured to the rod orstein d. 4
Through, the flange b-passes the rod or'. stem d, and around the rodd, where it passes through the chamber a, is apiece of rubber tubing, or its equivalent, covering the rod d from the flange orseat b to the collar c.
Outside of the rubber tubing is a spiral spring, E, which prevents the rubber from spreading when the rod d is pressed downward for the purpose of drawing theliquid, and also to force the rod 'd back-toits place when the pressureis removed.
Ascrew-cap, as usual, .is fitted' over the top of the casing, and holds the collare in place, and this collar is made to slide evenly in the casing.
The spring and tubing are secured between the collar c and flange b, and the collar being secured to -or made with the stem d, as said stem is passed-down to admit the fluid into the casing the said collar bears against the spring. and tubing, and they are compressed between it and the flange b, throwing the stem up again when released.
. The lower end of the stem is recessed' in three, more or less, places, e, and these recesses, in connection with the packing f, secured to the end of the stem, form the valve for the admittance of the uid.
By this device all unnecessary friction' is avoided, the packing-box is rendered perfectly tight, less liable to get out of repair, and cheaper in cost of construction than many of the prevailing modes.
p In manufacturing Huid-cocks we have been put to .inconvenience and loss of time, labor, and money, from the fact that .the cocks so soon get out of repair, and leak.
Again, it has frequently happened that vduring the process of galvanizing the packing has become partially or entirely destroyed, thus rendering vit neces'- .sary to 'take the cocks apart and insert new packing.
-By this mode of constructing a packing-boxsuchre- Y sults cannot take place, it being impossible for-the iugredienis'composing the galvanizing' fluid to penetrate into the packing-box. .What we claim as new, and desire to secure by Letters Patent, is-
l. The packing-tubing surrounding the stem d, in
combination with the spiral spring rE, when said tubllng and spring are -arranged between the flange or seat b and collar c, and operate together in the manner and for the purpose set forth.
2. The stem (l, provided with an. opening or openings near its lower end,Y and constructed as described, in combinationwith the tubing and spring, arranged' `as set forth. n y,
