I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, 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 is particularly applicable to stationary wash-bowls, bath-tubs and
analogous fixtures;-and my object is to so construct a combined "overflow" and trap,
that the bowl or other receptacle and said trap and overflow may, preferably, all be
constructed in one piece, and so arranged as not only to dispense with the ordinary
chain and plug but to render all parts of the overflow and trap accessible, so that they
may be easily and perfectly cleaned and maintained in a sanitary condition.
To this end, the invention consists in the combination and arrangement of parts as
hereinafter shown and described.
In the accompanying drawings.
Figure 1 is a vertical sectional view of a wash-bowl having the improvement applied
thereto.
Figure 2 is a like view showing a modification of the same.
Figure 3 is a sectional plan view in detail upon the line, Figure 1.
Figure 4 is a like view upon the line y, y Figure 1, and
Figure 5 is a longitudinal, sectional view of a bath-tub showing a modification of
the improvement applied thereto.
Like letters of reference indicate liko parts in the different Figures.
A, in the drawing, Figures 1 and 2, represents a stationary wash bowl of porcelain
or other suitable material, the rear wall A¹ of which is preferably made vertical or
substantially so, and straight, and in which, immediately above the bottom of the
bowl, is located a strainer A A secondary strainer A³, Figure 2 is also, by pre-
ference located at or near the top, so that one may remain open in case the other
becomes clogged. Upon the rear of the bowl I provide a semi-cylindrical part B,

page_text: which is extended considerably beneath the bottom of the bowl, for the purposes
hereinafter stated ;-said part forming a chamber B¹, in the rear of the bowl, which
is divided by means of a partition C, extending from a point below but near the top,
to one near the bottom of the part B ;-it being essential that said part B should extend
below the bowl, substantially as shown ;-but it is not essential that the whole chamber,
or chamber and trap should be integral, as the lower part may be separable and
attached to the main portion, as at B Figure 2. Between the back A¹ of the bowl
and the partition C, at a point on a level with or below the bottom of the bowl, is
formed a valve-seat D, adapted to receive a conical plug D¹, upon the lower end of a
rod D, which is operated in the manner hereinafter set forth. Upon the lower end
or depending portion of the part B, I provide an opening surrounded by a flange b,
adapted to receive a clamp b¹, which, in turn sustains a plug or cap 63 in position,
by means of a set screw 6³.
E is a pipe which is carried upwardly from, at or near the lower end of the part B,
until it connects with or attaches to the bottom of the bowl. From thence it is
curved downwardly, and is provided with a screwed part e, upon its end, to which
may be attached a waste-pipe, by means of a union" e. The pipe E, in
connection with the depending part B and partition C, serves to form a trap. The
upper portion of the pipe E is provided with a flanged neck or pipe E, to which may
be attached a vent-pipe E³, Figure 1, to prevent the water from being siphoned
from the trap. F represents the usual marble slab which forms the top of the bow!
when placed in position for use. Said slab is perforated at above the chamber B¹,
and the opening covered by means of a removable screw-cap G, through which tho
rod D2, loosely projects;a knob d, being formed thereon by which said rod is
manipulated. The rod D2, is preferably oval in form where it passes through said cap,
and the hole through the cap is of like shape. A short distance below the slab F,
a notch d', is formed in the rod or the rod is rounded, so that upon raising it to that
point by means of the knob and partially turning it, the rod is suspended and the
plunger D elevated and retained above the valve-seat;-thus permitting the water
to flow out beneath it. Upon partially turning the knob d, the valve falls upon its
seat. Should the water be permitted to flow into the bowl when the outlet is closed,
it is evident that as soon as it rises to the top of the partition C, it will flow over it
and down into the trap..
In Figure 1, the trap is represented as extending towards the front of the bowl.
Such a
In some cases it may be necessary to turn it an opposite direction.
construction is shown in Figure 2 in which a valve-seat, is also formed for the
reception of a float valve b'.
In Figure 5 I have shown a still further modification of said trap and overflow as
applied to an ordinary bath-tub A³. In such a case I prefer to bend the lower end
of the part B so as to carry it out to a point at or near the side of the tub ;---thus
rendering the opening which is closed by the cap b2, more easy of access.
It will be seen upon reference to the drawing, that upon removing the cap G and
plug, the entire interior of the chamber B, as well as the pipe E, is accessible
and may be readily cleaned and kept in a perfect sanitary condition by persons of
ordinary skill.
«
Moreover, the forming of the entire fixture in one piece as I prefer to construct
it, dispenses with the necessity for the usual "putty joints" and various metal parts
in common uso ;-the objections to which are obvious.
With my improved bowl, it is only necessary to make a "union" connection and a
wipe joint," with the respective pipes, after the bowl or other fixture, as the case
may be, is placed in position. Much labor is, therefore, saved in making connections
and a complete sanitary fixture is the result.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed as communicated to
me by my foreign Correspondents I declare that what I claim is :-
:―
First. The combination with a wash-bowl or similar feature, of an overflow

page_text: chamber extending from the top to a point considerably below the bottom of the
bowl, an opening as A³, communicating directly therewith, partition C, a valve-
seat D, between said partition and the body of the bowl, valve D¹, rod D³,
removable caps, as G 6, at the top and bottom of said chamber respectively, and
curved pipe E communicating with said chamber at a point near the botton
thereof, substantially as shown and described.
Second. The combination with a wash-bowl or similar "fixture," of a chamber B
extending from the top to a point below the bottom of the bowl, an opening as A³,
communicating directly therewith, partition C, a valve-seat D between said partition
and the body of the bowl, valve D', rod D³, removable_caps, as Gat the top and
bottom of said chamber respectively, and curved pipe E communicating with said
chamber at a point near the bottom thereof, said bowl, chamber, partition and trap
being all made integral with each other, and all of said parts being arranged and
constructed snbstantially as shown and described.
Third. The combination of the bowl A, a chamber B, partition C valve-seat D,
valve D¹, rod D³, caps G 63, bent pipe E, communicating with the lower part of
said chamber, and vent E, at the top of the bend thereon, substantially as shown and
described.
Fourth. The combination with a bowl or analagous "fixture," of double outlet
openings or strainers at the bottom and top respectively of said receptacle, and an
overflow chamber in direct communication therewith substantially as shown and
described.
