Improvements in or relating to Stop and Waste Cocks and the like.
A communication from LANDERS FRARY & CLARK, a Corporation organised under
the laws of Connecticut, and doing business at New Britain, State of Con-
necticut, United States of America.
I, ALFRED JULIUS BOULT of 111 Hatton Garden, in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to improvements in Right and Left Hand Stop and Waste
Cocks and the main objects of this improvement are simplicity and economy in
construction and convenience and efficiency in operation.
In the accompanying drawing-
Figure 1 is a front elevation of the stop and waste, with the outer end of the
handle broken off.
Figure 2 is a plan view of the same with the handle nut removed and a portion
of the handle head broken away, together with the reverse position of the handlo
in broken lines, and-
Figure 3 is a rear elevation.
A designates the hollow body of the cock with sockets 4 at each end for con-
nection with the proper pipes, the waste nozzle 5, while within its transverse bore
is the tapering plug all of substantially the ordinary form. The body A is pro-
vided with two stop shoulders or fixed stops 6, which, as shown extend inwardly
to the periphery of the plug B. Projecting from the plug at a point between the
stop shoulders 6 is a doubled faced stop 7. The outer end of the plug is provided
with an oblong rectangular shank 8, Fig. 2, upon which the head 9 of the handle 10
may be placed with the handle projecting in either direction. That is to say, the
oblong form of the shank makes the handle changeable thereon by a half a turn
on the plug. The handle is also provided with a double faced stop 11, which
extends down between the stop shoulders 6. The plug is also provided with the
ordinary threaded shank 12 upon which the handle nut 13 is screwed to hold the
handle in position. The position of the ordinary main passage 14 and waste
passage 15 in the plug is indicated by broken lines in Fig. 2.
When the handle stands in a position parallel to the length of the body A the
cock is opened, while the waste passage in the plug is closed by the rear side of
the case.
If the handle stands to the right as shown in Fig. 2 the right hand end
of the body is the house-side and the left hand end is the water-main-side. By
swinging the handle to the front one face of the plug stop 7 engages one of the
top shoulders 6 to stop the plug in the position to close the cock on the main side
and permit the water to drain off from the house side as in ordinary waste cocks.
When the handle is returned to the position shown in Fig. 2, one face of the handle
stop 11 engages the other one of the stop shoulders 6 and thus stops the handle in
the position shown. In order to change the cock to the other hand it is only
necessary to remove the handle and change its position a half turn on the plug as

page_text: indicated by broken lines in Fig. 2. When thus changed the operation is the
same as before only the handle swings from the left side to the front and the
opposite faces of the stops 7 and 11 act on the stop shoulders 6, one face of
the stop 7, acting on one of the stop shoulders and one face of the stop 11 acting on
the other stop shoulder.
My correspondents do not wish to limit themselves to the precise details of
construction shown but reserve the right to make such changes as may fairly fall
within the spirit and scope of this invention. For example the two stops aro
shown as working against the same pair of stop shoulders but they may be made
to operate the same with two pair of stop shoulders, one pair for the plug stop 7,
and another pair for the handle stop 11. so long as one face of one stop acts on one
stop shoulder to limit the movement of the plug in one direction, while one face
of the other stop acts on another stop shoulder to limit the movement in the
opnosite direction and one of said stops is changeable a half turn on the plug for
converting the cock to a right or left hand. While my correspondents for con-
venience have designated the stops 7 and 11 respectively as the plug and handlo
stops, it should be noted that when in use they are both mounted on the plug to
rotate therewith.
Having now particularly described and ascertained the nature of the said
Invention 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
A right and left hand stop and waste cock having mounted to rotate with its
plug, two double faced' stops, one of which is changeable by half a turn, and stop
shoulders on the body for engagement with said stops, one face of one stop acting
on one stop shoulder to limit the rotation of the plug in one direction, and one
face of the other stop acting upon another stop shoulder to limit the movement of
the plug in the opposite direction, substantially as described.
Dated this 14th day of September 1897.
