Improvements in Water Closet and like Joint Connections.
1, CHARLES RICHARD SCHMIDT of 200 East 24th Street, Baltimore, in the
State of Maryland, United States of America, General Manager of Works, 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 has relation to water closet and like joint connections, and has for
its object the provision of novel means for connecting supply or drainage pipes to
water closets or similar articles where it is desired to have a water-tight joint
between the water pipe and the article to which it is connected, and in which it is
desired to avoid injury to the article by any strain upon it that may be caused by
the accidental movement of the article itself or the connected pipe.
My invention consists in the provision of an elastic bushing, of novel form,
adapted to be inserted in an opening in the body of the water closet bowl or similar
article, and to closely embrace the entering end of the pipe union or section, so as
to make a water-tight and elastic joint that will serve to take up any strain due to
accidental displacement or movement of the bowl or pipe.
My invention further consists in the novel construction, combination, and
arrangement of parts hereinafter described and claimed.
Referring to the accompanying drawing, wherein, Figure 1 is a detached, sectional
view of a part of the water closet bowl and my improved connections, constructed
according to my invention.
Figure 2 is a sectional view of the same connected together,
Figure 3 an elevation of the spud end of the bowl.
Figures 4, 5, 6 and 7 are sectional views of modifications.
A designates part of the bowl of a water closet, and B, the spud end of the same,
consisting of a cylindrical boss having a slightly tapered aperture for the reception
of a bushing E, and a contracted opening at its inner end formed by an annular
flange D, having notches dd on its face for the reception of lngs ee on the
bushing E.
The bushing E, consists of a tubular section of rubber or similar elastic material,
and is of a size to fit snugly in the opening C, of the boss D, and slightly tapered
on the outside to correspond to the shape of the opening C. The lugs e, e, are
formed on the end of the bushing and enters the notches d, d, of flange D, their
purpose being to prevent the bushing from turning in its seat.
Upon the inside of the bushing E, are several parallel flanges a, a', the alternate
flanges a' being slightly wider than the flanges a, so that when pressed or folded
against the bushing by the union member or pipe the flanges a' will fold over or
against the flanges a, and will form ridges within which the union member which
enters the bushing will be closely embraced on the lines a², a².
The union member F, which enters the bushing, is formed with a bead, near its
inner end, which engages with one of the flanges on the inside of the bushing, and
serves to maintain the union member in the bushing under normal circumstances
and prevent its accidental withdrawal. The outer end of the union member F, is
formed with the usual flange f', and with the screw thread f2, for the reception of
the nut G.
The nut G, has an inwardly projecting flange g, and between this flange and the
outer end of the union member, an elastic washer H, is placed, which, when the nut

page_text: is screwed up tight, is compressed and spreads inwardly and tightly embraces the
service pipe I.
In operation, the bushing E, is inserted in the opening C, of the spud end B, the
lugs e, e, entering the notches d, d, and preventing the bushing from being turned
around. The union member F, is then pushed into the washer causing the
Hanges a, a, to lap over, as shown in Figure 2 of the drawing, and form ridges
which tightly embrace the union and form a water-tight joint with the outside of
the same.
The pipe end I, being inserted in the union either before or after the
latter has been inserted in the bushing, is held securely in position by tightening up
the nut G, which spreads the washer H, inwardly, causing it to tightly clasp the
pipe and form a water-tight joint.
The connection described is easily put in position and forms an effectual joint,
and the interposition of the elastic washer between the pipe union or spud and the
boss on the bowl serves to take up any strain or shock and prevents injury to the
boss or the bowl.
While the aperture in the boss B, has been described as tapering, and the
bushing E, has been described as of similar shape, both may be of even diameter
throughout, in which case the bushing should be made of such size as to fit quite
tightly in its seat.
In Figures 4, 5, 6 and 7, I have illustrated certain modifications within the scope
of my invention.
Figure 4 is a bushing having a tapered exterior with the larger end adapted to
enter a tapering socket in the spud. The inwardly projecting flanges are wedge
shaped in cross section, and are at right angles to the axis of the bushing.
Figure 5 is a bushing of the same external form, but with the internal flanges
canted or pitched inwardly, so as to render more easy the insertion of the pipe.
Figure 6 is a bushing having a tapering exterior terminating at its small end in
a cylindrical flange or offset and having but a single internal wedge shaped flange.
Figure 7 is a bushing having a cylindrical body, with a flaring entering end.
The internal flanges are of the form shown in Figure 1 or in Figure 5.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is :-
-
First. In a connection for water closets, the combination with an elastic bushing
having internal, parallel, annular flanges which overlap one another, of a cylindrical
union member entering said bushing and compressing said overlapping flanges,
substantially as described.
one another
Secondly. A bushing for water closet connections consisting of an elastic section
having internal annular flanges of such depth that they will overlap
when pressed against the inner wall of the bushing by an entering union member.
Thirdly. In a connection for water closets, the combination with an elastic
bushing having internal annular flanges, of a pipe or union member entering said
bushing and having an external head engaging with one of said flanges, substantially
as described.
Fourthly. A bushing for water closet connections consisting of a cylindrical
section of elastic material formed with inwardly projecting flanges, substantially
as described.
Fifthly. A bushing for water closet connections consisting of a tapered cylindrical
section of elastic material having internal annular flanges, substantially as described.
Sixthly. A bushing for water closet connections consisting of a cylindrical section
of elastic material formed with internal flanges of different widths, substantially
as described.
Seventhly. The combination with a water closet bowl having a hollow boss or
spud end of an elastic bushing adapted to fit in said boss and formed with internal
annular flanges, substantially as described.
Eighthly. The combination with a water closet bowl having a hollow boss formed

page_text: integral with the bowl and an elastic bushing fitting within said boss and formed
with inwardly projecting annular flanges of a spud or union member fitting in said
bushing, a nut screwing on the end of said spud and a washer between said nut and
spud, substantially as described.
Ninthly. In a pipe connection for water closets, the combination with the bowl
having boss B and flange D, with notches d, d, of the elastic bushing E, having
lugs e, e, entering the notches d, d, and inwardly projecting annular flanges adapted
to be folded against the inside of the bushing by an entering pipe or union member,
substantially as described.
Tenthly. A bushing for water closet connections consisting of a soft rubber cylinder
having one or more inwardly projecting annular flanges or ridges, of less thickness
than the length of the bushing, substantially as described.
