Improvements in Water Cocks.
A communication from WILLIAM ROBERTS, of 147, St. Patrick Street, Toronto,
in the Dominion of Canada.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex
Member of the Institution of Mechanical Engineers 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 :-
The object of the invention is to provide a cheaply made water cock which can
be depended upon to keep perfectly tight, and it consists, essentially, of a hard
rubber ball fitted into a cupped recess on the end of a swivel piece fitted on to
the end of the screwed spindle, the said ball being designed to fit into a cupped
seat formed around the inlet passage of the cock; substantially as hereinafter
more particularly explained.
Figure 1, is a view of the water cock partially in section to show the improved
valve in a closed position.
Figure 2, is a similar view showing the valve open.
In the drawing, A, represents a ball made of hard rubber secured by the
screw B, to the swivel piece C, connected in the usual way to the screwed
spindle D. The hard rubber ball A, is fitted into a cupped recess formed in the
end of the swivel piece C, which gives the said ball an ample bearing and holds
it in position with practically no strain upon the screw. Around the inside mouth
of the inlet passage E, a cupped seat F is formed to receive the valve A. This
cup-shaped seat provides ample bearing for the valve, so that it will be practically
indestructible and can be depended upon to remain perfectly tight. The passage
way for the screwed spindle D, is made slightly larger than the ball A, so that
the said ball will pass with ease through the said passage way. The improved
valve can be made very cheaply, as it is only necessary so far as the valve body
is concerned, to borc and screw the spindle's passage-way and face the cupped
valve seat F.
Although it is preferred to secure the rubber ball A, to the swivel piece C, it
is not absolutely necessary to do so, as the pressure of the water from the inlet
pipe E, will drive the ball into the cupped recess formed in the end of the swivel
piece C. Another point which should be observed and which is a distinct
advantage in the invention is, that when the valve A, is raised clear of its seat F,
the flow of water through the cock is unimpeded by any obstruction.
Having now particularly described and ascertained the nature of the said inven-
tion as communicated to me by my foreign correspondents and in what manner the
same is to be performed I declare that what I claim is,
1. A hard rubber ball fitted into a cupped valve seat formed around the inlet
passage of a water cock; substantially as and for the purpose specified.
2. A hard ball fitted into a cupped recess secured to the swivel piece of a
screwed spindle and arranged to fit into a cupped recess formed around the mouth
of the inlet passage of a water cock; substantially as and for the purpose specified.
3. A ball valve located between the inlet passage of the water cock and the
longitudinally adjustable swivel; substantially as and for the purpose specified.
Dated this 22nd day of June 1893.
