and Lavatories.
I, WILLIAM BARTHOLOMEW of the firm of B. Finch and Company of 82 Belvedero
Road Lambeth in the County of Surrey, Sanitary Engineer do hereby declare the
nature of this invention to be as follows:-
My Invention relates to improvements in fittings for baths and lavatories whereby I
regulate and control the supply of hot and cold water to the bath or bason and the
discharge of the waste therefrom, by means of a single handle actuating a shaft
carrying a cam operating the hot and cold water valves or taps, and a disc opening
and closing the valve on the waste pipe.
The cam I make of such form that it will, on the handle being turned to the one
position or the other as indicated by a dial plate, either fully open or close both hot
and cold water taps, or open the one more than the other, according to the tempera-
ture required.
The disc has a recess on its periphery, and is set upon the shaft in relation to the
cam in such a position that when this recess comes over the Connection with the
discharge valve permitting it to open the waste pipe, the cam will also close the water
supply valves.
When used as public bath fittings I propose to place the shaft horizontally and the
indicating dial outside of the bath room. For lavatories and private baths the shaft may
be placed vertically the indicating dial being horizontal. I may provide the dial with
a thermometer in connection with the bath and with a water guage to indicate level of
water in the bath.

Improvements in Water Supply and Discharge Fittings for Baths
and Lavatories.
I, WILLIAM BARTHOLOMEW, of the Firm of B. Finch and Company of 82 Belvidere
Road, Lambeth, in the County of Surrey, Sanitary Engineer 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 :-
My Invention relates to improvements in fittings for baths and lavatories whereby I
regulate and control the supply of hot and cold water to the bath or basin and the
discharge of the waste therefrom, by means of a single handle or key actuating a shaft
carrying a cam operating the hot and cold water valves or taps, and a disc opening and
closing the valve on the waste pipe.
The cam Imake of such form that it will, on the handle being turned to the one posi-
tion or the other, as indicated by a dial plate, either fully open or close both hot and cold
water taps, or open the one the one more than the other according to the temperature
required.
The disc has a recess on its periphery, and is set upon the shaft in relation to the
cam, in such a position that when the recess comes over the connection with the
discharge valve permitting it to open the waste pipe, the cam will also close the water
supply valves.
When used as public bath fittings I prefer to place the shaft horizontally and the
indicating dial outside of the bath room-For lavatories and private baths the shaft
may be placed vertically, the indicating dial being horizontal-I may provide the dial
with a thermometer in connection with the bath and with a water guage to indicate
level of water in the bath.

On the accompanying sheet of Drawing:-
Figure 1 is a section of a hot and cold water valve mounted on a breeches piece and
embodying part of my improvements.
Figure 2 is a cross section of same showing how the same shaft or spindle and key
or handle that controls the supply also opens the waste valve.
Figure 3 is a similar section to that Fig. 2, the shaft being however otherwise con-
nected with the waste valve.
Figure 4 shows in detail the connection between shaft and waste valve as at Fig. 3.
Figure 5 shows the dial plate and
Figure 6 is an elevation showing vertical shaft arrangement.
When the shaft A is turned by the key B it actuates the cam C, which, acting on
the rollers d, d, on the spindles D, D, opens or closes the hot and cold water valves E,
or the one more than the other according to the temperature required, as indicated by
the dial I; or one or other only. For the purpose of preventing concussion, the end
of each spindle D terminates in a chamber F, in the form of a piston, and the regu-
lating screw or cover f regulates the rapidity of closing.

page_text: The disc G is set upon the same shaft A as the cam C; it has a recess g on its
periphery and is so set on the shaft A that when its recess comes over the connection H
with the discharge valve it permits it to open the waste pipe K, the cam C then
permittting the simultaneous closing of the valves E. In the waste arrangement
shown Figs. 3 and 4 the shaft A has a crank L, and when its pin l is near the end of its
stroke in slot m it depresses the end of the lever M and opens the waste.
The arrangement shown Fig. 6, in which the shaft A is placed vertically, may
operate a waste arrangement similar to that shown Fig. 3, by means of the cam shaped
disc N carried on said shaft.
Having now particularly described and ascertained the nature of my invention and
in what manner the same is to be performed I declare that what I claim is:―
1. The combination of apparatus hereinbefore described and shown on the drawing,
whereby both the supply and discharge valves or taps of baths and lavatories are
operated by a same shaft and key or handle substantially as specified.
2. The cam C on the shaft A, in combination with the spindles D, D, and operating
the hot and cold water valves or taps E, substantially as described.
3. The cam C on shaft A, in combination with the disc G, having the recess g and
set on the same shaft A in the manner substantially as described for the purpose
specified.
