Improvements in Siphon-bottle Heads.
We, ALVIN WELLING, of No. 243 and 245, Pike Street, in the City of Covington,
in the County of Kenton, and State of Kentucky, one of the United States of
America, Liquor Dealer, and Louis FRITZ, 171 and 173, West Robins Avenue, also
of said Covington, in the County and State aforesaid, Manufacturer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to certain improvements in heads for siphon-bottles
such as are commonly employed for holding mineral and other carbonated waters,
and the object of the invention is to provide a device of this character which
shall be of a simple and inexpensive nature, and of a construction designed to
lessen as much as possible, the wear of the valve and other moving parts, so as
to prevent the leakage of gas from the bottle and to increase the durability of
the device.
The invention consists in certain novel features of the construction, combina-
tion and arrangement of the several parts of the improved head, whereby certain
important advantages are attained and the device is made simpler, cheaper and
otherwise better adapted and more convenient for use, all as will be hereinafter
fully set forth.
In the accompanying drawings which serve to illustrate the invention---
Figure 1 is a vertical section taken axially through the head, in the plane in
which the spout and valve-lever extend, and
Figure 2 is a sectional view similar to Figure 1, but taken in a plane at right
angles to the plane of the section in said figure.
Figure 3 is a detached detail view showing the valve-stem of the device in
axial section.
In these views 1 indicates the body-portion or casing of the siphon-head having
its lower part formed with an expanded socket wherein is screwed, in the ordinary
manner, a sectional coupling 2, for holding the head in place on the bottle-neck.
3 indicates the spout of the device extending from one side of the casing and
having a liquid passage arranged for communication with a duct or port 4 in the
casing and leading to the valve-chamber 5 therein. The port 4 opens into the
bottom of the valve-chamber and is controlled by a disk-shaped valve 6, held to
move in the valve-chamber and arranged to seat on the bottom thereof. A duct
or port 7 in, the body or casing 1, also opening into the bottom of the chamber 5,
serves to admit the liquid to the chamber when the valve is raised.
The valve 6 is centrally perforated for the passage of a valve-stem. 8, having a
reduced portion 9 whereon the valve is held by its own elasticity, above a
shoulder 9 formed at the base of said reduced portion. The lower end of the
stem & is rounded and plays in an axial socket 8 in the bottom of the valve-
chamber, said socket serving to guide the lower end of the stem for vertical
movement in the chamber 5 to open and close the ports 4 and 7.

page_text: The valve-stem 8 is formed with an enlarged cylindrical body portion 10
adapted to fit snugly in the valve-chamber 5 and against the underside of which
the valve 6 is held, and above said enlarged portion 10, the valve stem is extended
axially in the chamber 5, as shown at 11 said axial extension I being held at its
upper end in a socket 11" formed in a cap 12 screwing into the 'upper open end
of the casing 1. A spring 13 is coiled on the extension 11 of the valve-stem
between the cap and the portion 10 of the stem and serves, normally, to press the
valve-stem down to seat the valve on the bottom of the chamber 5.
The valve-stem and the valve carried thereby are adapted for operation by
means of a lever 14 pivoted at 15 in one side of the casing and having one end
projecting from one side of the device in position to be pressed by the fingers
in operating the valve, the opposite end 16 being flattened and extending through
an opening 17 formed longitudinally in the body 10 of the stem and extending
diametrically through the same. The extremity 16 of the lever is formed on its
upper surface or edge-portion with a rounded socket in which is held an anti-
friction roller 18, preferably formed of brass or the like and adapted for turning
movement in said socket. The upper part of the periphery of the roller projects
above the top-surface of the lever-arm 16 in position to engage the top-surface
of the slot 17 in the valve-stem body, and by preference, said top-surface of the
slot is formed with a removable wearing strip 19 of brass or the like, against
which the roller 18 bears.
By this construction, it will be seen that the wear of the parts is greatly
Jessened, owing to the rotative movement of the roller 18 which serves to distri-
bute the wear over the entire periphery of said roller, and said roller, together
with the strip 19 may be readily replaced when worn, so as to greatly increase
the life of the device. The roller is held in place in its socket in lever-arm 16
by the overhang of the upper curved sides of said socket and can only be removed
or inserted in said socket in a lateral direction. As the slot 17 is of a width to
snugly receive the flattened lever-arm 16, it is evident the roller cannot be dis-
lodged when the parts are assembled.
The valve-stem being guided at both its upper and lower ends, it is evident
that the valve is held securely against lateral movement in the valve-chamber,
so that wear on the edges of the valve is also lessened. When worn, the valve
may be slipped off the valve-stem S and replaced by a new one, being merely
held by its own elasticity upon the reduced part 9 of the stem above the
shoulder 9 at the base thereof.
The improved siphon-head made according to our invention is of an extremely
simple and inexpensive nature and is especially well adapted for the purposes for
which it is designed, since it is extremely durable and the wearing parts may be
readily replaced when worn and it will also be obvious from the above descrip-
tion that the device is capable of some modification without material departure
from the principles and spirit of the invention and for this reason we do not
wish to be understood as limiting ourselves to the precise form and arrangement
of the several parts herein set forth.
Having now particularly described and ascertained the nature of our said in-
vention, and in what manner the same is to be performed, we declare that what
we claim is:-
1. In a siphon-head, the combination of a casing having a valve-chamber, a
valve-stem therein having a body-portion and an axial extension above the same,
a valve held by the valve-stem, guides at bottom and top of the casing to receive
the valve-stem and extension, respectively, and means to move said valve-stem,
substantially as set forth.
2. In a siphon-head, the combination of a casing having a valve-chamber, a
valve-stem having a reduced portion forming a shoulder at the lower part of the
stem, a valve held on said reduced portion above the shoulder, a body portion

page_text: and an axial extension for the valve-stem above the valve, said casing having at
top and bottom, sockets to receive the extension and valve-stem, respectively,
and means to move the valve-stem, substantially as set forth.
3. In a siphon-head, the combination of a casing having a valve-chamber open
at its upper end and formed in its lower part with a socket, a cap screwing in the
open upper end of the valve-chamber and formed with a socket aligned with the
socket at the lower part thereof, a valve held on said stem, a body-portion and an
axial extension playing in the socket in the cap, a spring coiled on said extension
and means to move the valve-stem, substantially as set forth.
4. In a siphon-head, the combination of a casing having a valve-chamber, a
valve-stem therein having a body formed with a longitudinal slot, a valve on the
stem, a lever pivoted on the casing and having its arm engaged in said slot of the
valve-stem body and an anti-friction device carried by the lever arm in engage-
ment with said slotted body, substantially as set forth.
5. In a siphon-head, the combination of a casing having a valve-chamber, a
valve-stem therein having a body formed with a longitudinal slot, a valve on the
stem, a lever pivoted on the casing and having an arm engaged in said slot and
formed with a socket, and an anti-friction roller mounted to turn in said socket
and held against dislodgment therefrom, substantially as set forth.
