We JAMES LIGHTFOOT SHORROCK of 139 Manchester Road Accrington Mechanic,
and JOHN LIGHTFOOT SHORROCK of 16 Whalley Road Accrington Commission
Agent both in the county of Lancaster, do hereby declare the nature of our said
invention for IMPROVEMENTS IN APPARATUS FOR REGULATING THE FLOW OF
LIQUIDS CHIEFLY APPLICABLE TO BALL OR FLOAT VALVES," to be as follows:-
The object of our invention is by a simple, and efficient apparatus to effectively
regulate the flow of liquids.
On the valve spindle is attached the ordinary float, a double link, or swivelled
arm or other connection is connected from the valve spindle, to the box side, in
which the float works, or fixed in any other suitable position, the links being
adjustable as to their length, when the float lowers the spindle turns, and at the
same time opening the valve, by this means a plain surfaced spindle can be used,
and so there is comparatively little wear and tear, and no sticking or friction, as
compared with a threaded spindle.

Fig. 1 shews apparatus as applied to steam traps.
Fig. 2 shews the apparatus as applied to a ball tap, or float, the valve shewn
closed.
Fig. 3 shews valve open.
Fig. 4 shews the apparatus as applied to a tap.
Fig. 1. A is the valve spindle to which is attached a float B, with discharge
pipe C. D is the radius link or arm connecting the valve spindle A to the box or
trap side E or other fixture; the link is made adjustable by hook F, set screw G,
and thumbscrew H, when the float lowers it turns the spindle, and the radius link
draws in the spindle and opens the valve, as the float rises the pressure pushes the
valve on to its seat closing it, by this arrangement screw valves are dispensed with,
and by using plain surfaced valves there is less friction and wear and tear; the
arrangement shewn in Figs. 2, and 3 acts in a similar manner. Fig. 4 shews the
radius link applied to a tap by putting a spring K on the valve spindle, it will do
for either low or high pressure, D is the link connecting the wheel L on the
spindle with the body of the tap; on turning the wheel, the radius link pulls
inwards, and opens the valve the spring or the pressure returns it to its seat.
.
Having now particularly described and ascertained the nature of our said 2
invention and in what manner the same may be performed, we declare that what
we claim is
The application of a radius link, arm, or chain for operating valves and taps of
any suitable description as shewn and described.
