Improvements in Arrangements for Intermittently Drawing Off
Liquids from Jars and other Vessels.
I FREDERICK SPEEDY of No. 67 Clifton Street, Wandsworth Road in the County
of Surrey, Brewer do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
My invention consists of the improvements hereinafter described in arrangements
for drawing off liquids from jars and other vessels such as beer jars and the vessels of
water filters and other vessels used for containing liquids and from which the liquids
are required to be drawn off or to be permitted to flow out intermittently at or near
the lower part.
According to my said invention I provide for the outflow of liquid from the jar or
vessol by means of communicating passages formed in a protuberance on the jar or
vessel at the part where the liquid is required to be drawn off. And I provide for
opening and closing communication between the said passages by means of a valve
mounted in one of them the said valve consisting by preference of a ring of india
rubber carried by a plug capable of being readily moved to and fro in the passage in
which it is mounted.
I will further describe my invention with reference to the accompanying drawings
in which a convenient arrangement for the purpose hereinbefore stated is illustrated.
Figure 1 of the said drawings is a side view of a beer jar provided with the said
arrangement.
Figure 2 represents a portion of the said jar showing a front view of the said
arrangement drawn to a larger scale.
Figure 3 is a section of the said arrangement taken on the line A. A. (Figure 2)
showing the outlet of the jar closed and
Figure 4 is a similar section showing the said outlet open.
In the following description the parts of the drawings aro referred to by the letters
and figures marked thereon. The same letters and figures of reference indicate the
same parts in all the figures of the drawings.
a is the protuberance in which the communicating outlet passages are formed.
b, c, d are the said passages. e is a ring of india rubber which constitutes the acting
part of the valve hereinbefore referred to. f is the plug carrying the said india
rubber ring e which plug is mounted in the passago c and has a head / formed on it
which projects beyond the face of the said protuberance a. is a screw thread
formed on the said plug which engages with a corresponding screw thread formed in
the outer end of the passage c.
The plug may be made of vulcanite or of wood or
of metal or of any convenient material.
The action and method of using the said arrangement are as follows;-
When the plug is in the position shown in Figure 3 the india rubber ring e bears
against the part c' of the passage c and cuts off communication between the passages b c.
When it is desired to draw off liquid from the jar a the projecting head f¹ of the
plug is turned to the left whereby the said plug is caused to move in the passage c
outward or away from the passage b. When the said plug has thus been withdrawn
to the position shown in Figure 4 the communication between the passages b, c, d is
fully open and the liquid in the jar is free to pass therefrom through the said passages
and may he received in a vessel placed below the passage d. The escape of liquid
between the screwed parts of the passage c and plug fis prevented when the parts
are in the position shown in the said Figure 4 by the india rubber ring e which is
slightly compressed in the space between the said passage c and plug f. When the
required quantity of liquid has been drawn from the jar the flow of liquid therefrom

page_text: is stopped by turning the head of the plug to the right until the india rubber
ring e is firmly pressed against the part c¹ of the passage c as shown in Figure 3.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I wish it to be understood
that my said invention is not limited to the precise arrangement illustrated in the
accompanying drawings and herein before described with reference thereto as the
arrangement illustrated in the said drawings may be considerably varied without
departing from the nature of my said invention but I declare that what I
claim is
Arrangements for intermittently drawing off liquids from jars and other vessels
consisting essentially of communicating passages for the outflow of liquid formed
in a protuberance on the jar or vessel and means for opening and closing communica-
tion between the said passages arranged and acting substantially as hereinbefore
described.
