PROVISIONAL SPECIFICATION.
Improvements in Thimble Sockets for Soil Pipes and the like.
I, JOHN JONES of 40 Sydney Street, Chelsea, in the County of Middlesex,
Builder, do hereby declare the nature of this invention to be as follows:-
This invention relates to thimbles, ferrules or similar socket devices usually
employed at the foot of soil pipes or other pipes of lead or soft metal which it is
difficult to connect satisfactorily with the earthenware and iron drain-pipe.
At present a thimble or ferrule is employed usually made of brass, very thin and
with a small flange at the bottom, the upper edge going inside the soil pipe which
is placed upon the outside of the ferrule and soldered to it. This arrangement has
several drawbacks, some of which are that the ferrule being made of brass to
facilitate the soldering is very expensive and the end of the ferrule projecting
upwards inside the soil pipe is likely, sooner or later, to catch the contents of the
pipe and to cause an obstruction. My improved ferrule or thimble is constructed
as follows:-A cylindrical body carries a broad flange at the base adapted to fit
inside the socket of the earthenware drain-pipe; at the top of the cylindrical
portion the ferrule is swelled out to form a socket into which the soil or other pipe
may be fitted the inside of the ferrule being of the same diameter as the inside of
the soil pipe so that no projecting edge is left. The joint may be made in any
convenient and well known manner according to the material of which the ferrule
is made and the shape of the socket. Thus, the thimble may be made of ordinary
cast iron, malleable cast iron, malleable iron or the like, preferably galvanized, tinned,
or similarly treated to prevent rusting; when this is the case the lead pipe can be
soldered to the thimble. A caulked joint may be made or it may be run in with
solder or other suitable metal or alloy and if desired the flange may be flaring, or
trumpet-mouthed or otherwise enlarged to facilitate the making of the joint.
At present the drain-pipe is provided at the end with a curved earthenware or
iron socket pipe but it is sometimes convenient to let the drain terminate on its
natural line and to provide the bend in another way. This I do by forming the
bend in the thimble itself which may be made of the required length for the purpose.
I prefer also to make this ferrule of greater length than that of the usual kind in
order to raise it clear of the ground so that the joint with the lead soil pipe may be
accessible. At present the ferrules are made as short as possible on account of the
expense due to their being made of brass.

COMPLETE SPECIFICATION.
Improvements in Thimble Sockets for Soil Pipes and the like.
I, JOHN JONES, of 40 Sydney Street, Chelsea, in the County of Middlesex,
Builder, 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 relates to thimbles, ferrules or similar socket devices usually
employed at the foot of soil-pipes or other pipes of lead or soft metal which it is
difficult to connect satisfactorily with the earthenware or iron drain-pipe.

page_text: At present a thimble or ferrule is employed usually made of very thin
brass, and with a small flange at the bottom, the upper edge going inside the soil-
pipe which is placed upon the outside of the ferrule and soldered to it. This
arrangement has several drawbacks, one of which is that the end of the ferrule
projecting upwards inside the soil-pipe is likely, sooner or later, to catch the
contents of the pipe and to cause an obstruction. My improved ferrule or thimble A,
as indicated in section in Figure 1, of the accompanying drawings, is constructed
as follows;-
A cylindrical body A carries a broad flange A' at the base adapted to fit inside
the socket B¹ of the earthenware or other drain-pipe B, which latter (B B') is
shown in dotted lines in Figure 1; at the top of the cylindrical portion A the
ferrule is swelled out to form a socket A' into which the soil or other pipe C
(represented in dotted lines) may be fitted, the inside of the part A of the ferrule
being of the same diameter as the inside of the soil pipe C as shown, so that no
projecting edge is left. The joint between C and A may be made in any
convenient and well-known manner according to the material of which the ferrule
is made, and the shape of the socket. Thus, the thimble A may be made of brass
or aluminium, also of ordinary cast-iron, malleable cast-iron, malleable iron, or the
like, preferably in the case of iron, galvanized, tinned, or similarly treated to
prevent rusting; when this is the case the lead pipe C can be soldered to the
thimble A. A caulked joint may be made between A and B or it may be run in
with solder or other suitable metal or alloy and if desired the flange may be flaring,
or trumpet-mouthed or otherwise enlarged to facilitate the making of the joint.
At present the drain-pipe is provided at the end with a curved earthenware or
iron socket pipe but it is sometimes convenient to let the drain terminate on its
natural line and to provide the bend in another way.
This I do as shown in
section in Figure 2, by forming the bend in the thimble A itself which may be
made of the required length for the purpose and is preferably provided with a
supporting-foot A³, the thimble socket shown in Figure 2 being otherwise of the
construction before-described with reference to Figure 1. I prefer also to make
this ferrule A of greater length than that of the usual kind in order to raise it
clear of the ground so that the joint with the lead soil-pipe C may be accessible.
Like letters indicate like parts in both figures of the drawing.
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 ;-
1. A straight thimble socket for drain pipes comprising a straight portion A a
flange A and an enlarged socket A substantially as described and illustrated in
Figure 1 of the accompanying drawings.
2. A curved thimble socket for drain pipes comprising a curved portion A a
flange A and an enlarged socket A' substantially as described and illustrated in
Figure 2 of the accompanying drawings.
3. A curved thimble socket for drain pipes comprising a curved portion A a
flange A' an enlarged socket A' and a supporting foot substantially as described and
illustrated in Figure 2 of the accompanying drawings.
Dated this 12th day of October 1894.
