A Keyles
I, JOHN HALL MCDONALD, Partner of McDonald & Wilson, 51, McPhail Street,
Calton, Glasgow, General Brassfounders and White Metal Manufacturers, do
hereby declare the nature of this invention to be as follows:-
-
This invention relates to tube cranes or cocks for kitchen sinks and consists in
so mounting the tube of the crane that the ordinary key is dispensed with thus
making the whole cock more compact and ensuring its occupying less space in the
sink, and at the same time prolonging the life of the cock.
In the ordinary kitchen sink crane or cock the tube is connected thereto by a
tapered key which with the repeated movement of the tube, together with the
sand or grit from the water, soon tends to wear loose and cause the cock to leak.
When this happens the key has to be tightened up by a nut working on a screw
at the one end thereof which however soon becomes useless and necessitates the
employment of a new key.
In accordance with my invention I form the cock proper, which may be of the
usual "screw down"
form, with a stuffing box at the side thereof. The tube of
the cock is connected to a short horizontal tube which is provided with a flange
of suitable dimensions adapted to be placed into the said stuffing box so that after
the insertion of suitable packing, the whole can be screwed up to form a tight
joint. The water ways are in this case in direct line so that there is less tendency
for sand to become lodged in the joint and affect it by grinding. Also by means of
the said stuffing box the joint can be easily and quickly tightened after having
become slackened by wear.
It will thus be seen that by situating the tube directly at the side of the cock
less space is occupied thereby than with the ordinary cock having a key situated
in front thereof and also that the cock can be used for a much longer period than
hitherto.

My invention may also be applied to cocks of what are known in the trade as
Tambart tune with advantage.

page_text: 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 follow-
ing statement: -
This invention relates to tube cranes or cocks for kitchen sinks and consists in
so mounting the tube of the crane that the ordinary key is dispensed with thus
making the whole cock more compact and ensuring its occupying less space in the
sink, and at the same time prolonging the life of the cock.
In the ordinary kitchen sink crane or cock the tube is connected thereto by a
tapered key which with the repeated movement of the tube, together with the
sand or grit from the water, soon tends to wear loose and cause the cock to leak.
When this happens the key has to be tightened up by a nut working on a screw
at the one end thereof which however soon becomes useless and necessitates the
employment of a new key.
But in order that my said invention may be more readily understood and easily
carried into effect I will proceed to describe the same with reference to the accom-
panying drawings in which:—
Fig. 1 is a front elevation partly in section and
Fig. 2 a side view complete of a crane or cock constructed in accordance with
my said invention.
Referring to the said drawings I form the cock proper, which may be of the
usual screw down" form, with a stuffing box A at the side thereof. The tube B
of the cock is connected to a short horizontal tube C which is provided with a
flange c of suitable dimensions adapted to be placed into the said stuffing box A
so that after the insertion of suitable packing D, the whole can be screwed up to
form a tight joint. The water ways are in this case in direct line so that there
is less tendency for sand becoming lodged in the joint and affect it by grinding.
Also by means of the said stuffing box the joint can be easily and quickly tightened
after having become slackened by wear.
It will thus be seen that by situating the tube directly at the side of the cock
less space is occupied thereby than with the ordinary cock having a key situated
in front thereof and also that the cock can be used for a much longer period than
hitherto.
My invention may also be applied to cocks of what are known in the trade as
the Lambert type, with advantage.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. A keyless tube crane or cock for kitchen sinks, constructed and operating in
the manner as herein before described and shewn in the accompanying drawings.
2. Mounting the tube of kitchen sink cranes or cocks within a stuffing box
formed upon the. cock, substantially in the manner as and for the purposes
described and shewn in the accompanying drawings.
