Appurtenances.
I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of 53, Chancery
Lane, in the County of Middlesex, Fellow of the Institute of Patent Agents, do
horeby declare the nature of this invention (a communication to me from abroad by
Benjamin C. Smith, of 120, St. Mark's Avenue, in the City of Brooklyn, County of
Kings, and State of New York, United States of America, Manufacturer,) and in
what manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
One object of the invention is to provide a series of expansible and contractible
pipes and connections for washing tanks whereby washing tanks of various dimensions
may be readily connected to the soil pipes. . Another object of the invention is to
improve the construction of cocks for washing tanks and the like so that they may
be shorter than heretofore, while permitting the proper amount of water to pass.
Another object of the invention is to improve the manner of connecting the cocks
in washing tanks to the water supply pipes. And another object of the invention
is to improve the stands for supporting the washing tanks.
The Invention consists in the novel details of improvement and the combinations of
parts, that will be more fully hereinafter set forth and then pointed out in the claims.
Reference is to be had to the accompanying drawings forming part of this
specification, in which figure 1 is a perspective view, partly broken away, of a set
of washing tanks having the improvements applied. Figure 2 is a vertical cross-
section on line c-c figure 1. Figure 3 is a detail side view of the stand for
supporting the tanks. Figure 4 is an enlarged detail sectional view on line k-k
figure 3. Figure 5 is an enlarged detail sectional view of the improved cock and the
water supply pipe connected therewith, shewn applied to one of the walls of a washing
tank. Figure 6 is an enlarged central sectional view through the waste pipes and
connections, shewing the details of construction of the improved waste pipe con-
nections. Figures 7 and 8 are similar views of modified forms of construction.
In the accompanying drawings A represents a series of stationary washing tanks, of

page_text: which there may be two or more, three being shewn in the drawings. a are the
tubular outlet plugs that pass through the bottoms of the tanks and are suitably
held thereto. The tubular plugs a are screw-threaded externally beneath the tanks
and receive nuts b which nuts each have an internal annular flange d at one end.
Bare T-or other shaped couplings which at one part receive the smooth or unflanged
ends of intermediate vertical pipes D that are adapted to slide within the couplings B.
The opposite end of each vertical pipe D has an external flange e. The flanged end
of the vertical pipe D is held in the nut b, and the nut & drawn upon the plug a the
flanged on the nut pressing the flange e against the end of the plug a thereby making
a tight connection and holding the pipes securely upon the plugs a. The unflanged
end of the vertical-pipe D may now be soldered to the couplings B if desired, to make
a close connection. Thus the plugs a are adjustably connected with the couplings B
by the intervening vertical-pipes D, there being one coupling to each tank. But the
intermediate vertical pipes D'could be dispensed with and the couplings be secured
directly to the plugs a by the nuts b. One or more of the horizontal branches of the
couplings B have external threads to receive nuts that have inwardly projecting
flanges d As in figure 1, every two couplings B are connected by a horizontal
pipe D of suitable length, which is flanged at one end and unflanged at the other.
The flanged end of each pipe D2 is held by the flange 2 of the nut 2 and drawn
up close to the coupling by the nut. The other or unflanged end of the pipe D³
is now inserted in its proper coupling B for the required distance and may be
secured by solder, if desired. Thus it is seen that one coupling has the pipe Da
drawn up close by the nut while the next coupling receives the unflanged ond
of the pipe. Instead of securing the unflanged ends of the pipes D' to the couplings B
they may be slipped loosely into the coupling and held in position and leakage pre-
vented at the junctions by the nuts 63, the flanges of which compress packing or
washers around the pipings D2 and between said coupling and the flanges d³, as
seen in gure 7. There may be any number of plugs a pipes and couplings connected
thereto. One of the couplings B connects by a pipe D³ with a soil pipe or outlet
pipe or with a trap F, see figure 1, but any of the couplings B could carry the
pipe D³. As shewn in figures 1 and 8, one of the pipes D is connected by the nut b
and flanges d and directly with the plug a while its unflanged end passes freely
into the coupling B. As shown in figure 7, the coupling B is a 4-way coupling and
two pipes D connect said coupling with the end plugs a while said coupling is
connected by the pipe D with the central plug a. The pipe D leads from one
branch of the 4-way coupling. But the parts may be variously arranged and one
or more intermediate pipes D not having flanges e, as in figure 8, could be inserted
in the system, where a greater length of piping is required. As shewn, the packing
will be held by the nuts 63, as before described, to prevent leakago.
With the above construction, the plugs a may be at varying distances apart and be
readily connected by the ripes DD and couplings B by passing the unflanged end of
a pipo further in or out of the coupling until the required position is found. The
parts are then suitably fastened. The trap F may be of any desired construction and
suitably connected with the soil pipe. With this improved system of piping, the trup
can be set in position and the junction of the parts securely made with very little
trouble. With the above arrangement, a system of piping for washing tanks may be
sold that will fit any tanks and an ordinary workman can readily set up the piping.
This is a great saving on the practice heretofore employed of measuring and cutting
cach pipe and then soldering the pipes together. This system also overcomes the
danger of the pipes becoming loosened and water escaping.
Referring now to figures 1, 2, and 5, G represents a cock made according to this
invention wherein 7 is the plunger that is adapted to come over the seat h to prevent
the passage of water and is the outlet nozzle of the cock. As seen in figure 5, the
seat for the plunger is behind the nozzle i and the plunger is also behind the
nozzle i and within the threaded portion of the cock. By this means a shorter stem j
for the plunger can be used and thereby a shorter barrel for the cock. 2 is a short
pipe or tube which at one end passes within the wall mn of the washing tank A and

page_text: receives the threaded end of the cock G whereby said cock is held in position in
the washing tank. A nut n on the pipe is pressed up against the wall m of the
washing tank to securely hold the parts in position. H Hare hot and cold water
pipes that extend horizontally along, and parallel with, the back wall of the washing
tanks, as shewn in figure 2, said pipes being about on the same plane whereby one
is brought nearer the tank than the other. These pipes H H are connected by the
short pipes with their respective cocks G within the tanks, one of the pipes being
longer than the other so as to over-reach the pipe H and be connected with the
pipo H that is farther from the tanks. This is clearly shown in figure 5. By this
construction the pipes can be readily adjusted and will be securely held when in
position.
Referring now to figures 1, 2, 3, and 4, I is a stand or support upon which the
tanks A are placed. This stand consists of a frame-work having a horizontal upper
bar o upon which the tank A rests, as seen in figure 2. O is an upwardly extonding
arın or brace that is pivotally carried by the stand I and passes along, or rests
against, the outer side of the tank A, as in figures 1 and 2. The arm has an
inwardly projecting lug p which is provided with an aperture to receive a screw or
bolt that passes through a suitable hole near one edge of the stand I, see figure 1.
When adjusting the tanks upon the stand I said stands are first placed in the
desired position upon the floor and the tanks placed upon the horizontal part o of
the stands and are then pushed up against the upright arm O. Said arm is then
turned on its pivot q until it rests closely against the side of the tank A where-
upon the screw or bolt q is drawn up to securely hold it in position. The upper end
of the arm O may be secured to the wooden rim P that is placed upon the top
of the tanks.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
