Improvements in Joints and Couplings for Sanitary Appliances.
I, HENRY FREDERICK BUCHAN, of 67 Clapham Park Road, Surrey, Plumber
and 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 :-
This invention has for object, certain improvements in sanitary appliances,
notably in means for securing closet pans, earthenware bends, elbows or traps in
sockets of special make to enable the socket and pan dip or other terminal to be
easily attached by cement, or other agent, and also to enable metal connections
to be made with glazed ware S, D, P, or other trap ends for the attachment
of metal soil pipes, also to attaching a flange lip to a lead pipe in combination with
a sliding collar, or nut by which such a pipe can be connected up like an union
joint, or for affixing to the S, D, or P trap at any desired position, say, at the side
for ventilating, for overflow from a closet pan, a cistera, waste from baths, sinks,
or like purposes.
The sockets may be plain, corrugated, fluted, or otherwise shaped either
horizontally, vertically, or anglewise for keying the cement, and provided with a
shoulder or bearing for the pan dip pipe or trap end to lodge on, and ribs or fillets
in sections, or segments, or screw threads may be arranged at the lower parts for
the easy connection of ferrules similarly shaped, and which can be drawn up, and
be partially, or wholly turned for attachment with or without the use of packing
of some kind. Said ferrules may have square faces for a wrench to act upon
them, or slots can be formed through, or in the projections to be turned by a jaw
key, or equivalent appliance.
purpose screw threading a collar flange on the end after placing an union over
the pipe, so that the union or nut can be screwed upon the threaded extension for
making a joint without the usual plumbers wipe. In some cases, the pan dip or
trap, or pipe may have scorings (vertical or other), and the inner faces or edges of
the sockets may have V or other projections for localizing the pan, or pipe end,
there being a well or recess below the level of the shoulder, or bearing for the
cement to enter and prevent leakage. The lead flange joint is specially applicable
to overflows and right angled pipes, particularly those of baths, sinks, wash basons,
(tilt, or others), and can be fitted to existing pipes, bends, and traps where desired.
My invention will be clearly understood by the annexed drawings.
Figure 1 is a part sectional elevation of a socket with plain wall and a segmental
ribbed neck.
Figure 2 an exterior elevation of aghorizontally corrugated socket, the neck
having circular ribs.
Figure 3 shows a similar socket and neck except that the corrugations are
vertical, as in the plan view Figure 4, the shoulder or bearing being also shown
corrugated on the outer wall, and having spikes or projections for engaging the
scorings of a pan dip pipe, or trap, if made with them."
Figure 5 represents a socket with the corrugations or flutings arranged
anglewise.
Figure 6 iudicates a pipe end with segment ribs upon it, and with a travelling
collar with segmental lips to pass up between the ribs on the neck.
Figure 7 is a plan of the travelling collar, the outer extensions having holes
through them for a spiked key to engage in for turning said collar.
In Figure 8 the plan shows the outer extension with notches for the same
purpose.

page_text: According to Figure 9, the end of the pipe is flanged preferably by screwing on
after the travelling nut, Figures 10 and 11, has been passed over the pipe, said
flange may however be soldered on, if desired.
According to Figure 1, A is a plain walled socket with shoulder B therein, said
shoulder being hollow or solid as indicated on the two sectional parts to serve
as bearers for an earthenware closet pan dip, a connection, a trap end, or the
like to rest on. C is the neck with segmental screw threaded ribs D on the
exterior for the reception and fixture of the sliding collar E which is slipped over
the connection F for screwing on to the neck C of the socket A, the connection F
being also provided with segmental ribs G for the lugs H of the collar E to bear
against upwardly in contradiction of the downward pressure on the ribs D of the
socket neck C. The connection F, say of brass, can be attached by plumber's
joint to a lead, or other metal pipe, whether it be a soil pipe, a sink pipe, a bath, or
an overflow from a closet, or a cistern. The collar E may have a square, or other
form for a spanner to turn it by, or swells or projections I may be arranged as at
Figures 7 and 8, in which holes or notches J, J, for a claw of any kind by which
it could be turned in places where a spanner is not available.
In certain kinds of closet pans, wash basons, baths, and the like an overflow pipe
is provided in connection with the down pipe, the trap, or other part, and to enable
such pipe to be readily affixed, I screw, spread out, or otherwise form a flange K on
the end, as at Figure 9, then by slipping a threaded collar L over the pipe M,
I can attach said pipe to a threaded side projection of the down pipe, trap, or the like,
as at Figures 10 and 11, which I here show as applied to the side of a trap of a
bath, a sink, or a wash bason down pipe, but it is equally applicable to all or any
kind of sanitary fittings.
N is a plug also in the side of the trap to be removed for clearance purposes
should the trap or pipe become choked from any cause.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The described means and appliances by which metal connections can be made
with earthenware pipes, dips, traps, or the like.
2. Corrugating or fluting the body of connections by or to which earthenware
pans or basons can be put in relation to metal down pipes as described and
substantially as shown.
3. Screw threading the lower parts of metal connections affixed to earthenware
pans and basons for the fixation of the downflow, or soil pipe by a sliding collar
capable of fixing one to the other, as and for the purposes set forth.
4. Flanging the end of an overflow pipe, and employing a slip, or runner collar
over same to engage a threaded extension projecting from the side of a pipe, bend,
trap, or the like, as described and substantially as represented.
