Year: 1896

page_text: I, JOHN WATKINSON of 48 Margaret Street, Everton in the City of Liverpool,
Plumber, do hereby declare the nature of this invention to be as follows:-
This invention has for its object a stop cock of an exceedingly simple character
and that shall have a straight through flow. The plug is terminalled on the
spindle and slightly conical and works in a slightly conical seat having passages on
each side. The spindle is screwed so as to screw into the upper portion of the
barrel which is separated from the lower portion but united by an interior flanged
Dut with an annular washer. A washer on the top of the plug prevents water or
other fluid passing in an upward direction. The upper portion of the barrel is.
fitted with a gland in the usual manner. The above describes my actual experi-
mental cock and one of the principal advantages of it is that as a ground cock all
the removable portions are above and there is no screw below, consequently there
is no necessity of getting below the line of pipe. At the end of the barrel.
I prefer to place a short projecting pin passing into a hollow in the plug.

I, JOHN WATKINSON, of 48, Margaret Street, Everton, in the City of Liverpool,
Plumber, 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:-
This invention has for its object a stop cock of an exceedingly simple character
and that shall have a straight through flow.
It is best described by aid of the following description, reference being had to
the accompanying drawings, in which,
Figure 1 shows my most improved form of tap,
Figure 2 modification of it.
In these, A. is the plug terminating the spindle B. This is made slightly conical
to fit its seat and more conical in Figure 2 than Figure 1, owing to the seat being
shorter. C C is the through passage. In Figure 1 it has a straight through flow,
while Figure 2 shows a modification of my design so as to adapt it to the ordinary
plan. Spindle B has a screw thread D turned on it, and the upper portion of the
barrel E has a corresponding screw thread in which it turns. The upper portion
of the barrel E is made in a separate piece from the lower portion F, but the two
are united by a flanged nut G and annular washer H. A washer I prevents water
or other fluid from passing in an upward direction. The upper portion of the
.
حلم

page_text: barrel E is fitted with a gland J in the usual manuer. The two cocks here shown
differ only, except in the arrangement of passage C and a plug A, which in
Figure 2 are arranged on the ordinary plan, in outward design from each other,
Figure 2 being added simply to show how part of my improvements can be
engrafted on the ordinary tap without all of them being used. One of the principal
advantages of my cock is that acting as a ground cock, all the removable portions
are above and there is no screw below, consequently there is no necessity of getting
below the line of the pipe. At the end of the barrel, I may sometimes place a
short projecting pin passing into a hollow in the plug. In practice however I find
this of little or no use as the spindle works perfectly steadily without this
guiding piu.
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. The improvement in stop cocks or taps, which consists in arranging the
spindle of the cock with a conical end so as to itself act as a valve in combination
with a screw in the divided barrel, substantially as described.
2. The combination of the screwed spindle B, the screwed upper barrel E, the
lower barrel F and the washer I substantially as and for the purposes described.
3. The arrangement of tap with straight through flow, substantially as herein
described and illustrated.
