PROVISIONAL SPECIFICATION.
Improvements in Heating Apparatus for Public Buildings,
Dwelling-houses, and Apartments.
I, JOHN WORSFOLD of 54, Landcroft Road, East Dulwich, in the County
of Surrey, Engineer, do hereby declare the nature of this invention to be as
follows:
This invention relates to that class of apparatus for heating public buildings
dwelling houses apartments, and other places, by means of steam or hot water,
which are known as "radiators," the object of the invention being to simplify the
construction of these apparatus, so that the columns, or loops," as they are
technically called may be renewed, as occasion requires, without difficulty.
66
In carrying out this invention, there is a base piece and a top piece common to
several columns or loops, and there is a reservoir in the base, and also one in
the top, which reservoirs are connected together by the loops, as in other apparatus
of the kind.
The present invention consists in the mode of securing the loops to the reservoirs,
so as to make steam or water tight joints, and at the same time to provide for the
ready removal and renewal of a loop, when necessary, without taking the whole
apparatus apart, and to this end I provide openings in the top of the of the
lower reservoir and the bottom of the upper reservoir, which holes are of conical
shape, and turned perfectly true. Into these holes I fit hollow gun metal plugs of
corresponding form externally, turned true, and internally threaded, say, with a
right hand screw, to receive one end of a short piece of threaded pipe usually
termed a nipple. The other end of this nipple is screwed or threaded in the
contrary direction, say, with a left hand screw, and fits into the central tube of the
loop, an annular flange on the pipe separating the two threads.
The nipple is screwed into the central tube of the loop from the inside of the
base and top plate and the flange draws the tube down onto the base piece or the
top piece on to the tube so as to make tight joints.
The gun metal plugs are then screwed down onto their seats in the reservoirs and
the whole may be fastened together by two or more clips or straps, or in any other
convenient manner.
The base may be connected with the external air so that fresh air may enter and
become heated before it passes into the apartment.
Dated this 27th day of November 1893.

Improvements in Heating Apparatus for Public Buildings,
Dwelling-houses, and Apartments.
I, JOHN WORSFOLD of 54 Landcroft Road, East Dulwich, in the County of
Surrey, 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 relates to that class of apparatus for heating public buildings,
dwelling houses, apartments, and other places, by means of steam or hot water,

page_text: which are known as
'radiators,”—the object of the invention being to simplify the
construction of these apparatus, so that the columns, or "loops," as they are
technically called, may be renewed, as occasion requires, without difficulty.
In carrying out this invention, there is a base piece and a top piece common to
several columns or loops, and there is a reservoir in the base, and also one in
the top, which reservoirs are connected together by the loops, as in other apparatus
of the kind.
The present invention consists in the mode of securing the loops to the reservoirs.
so as to make steam or water tight joints, and, at the same time, to provide for
the ready removal and renewal of a loop, when necessary, without taking the whole
apparatus apart.
In the accompanying drawing,
Fig. 1 is a front elevation of a radiator, having both steam or water passages
and air passages in the same loop, and Fig. 2 is a sectional elevation, showing the
manner of securing the loops to the steam or water reservoirs, and Fig. 3 is a
sectional plan view.
Fig. 4 is a sectional elevation, shewing the steam or water tube without the
air tube.
Fig. 5 shews, partly in section, a modification in the form of the loop, and
Fig. 6 shews the "nipple" detached.
A is the base, which may be formed in one with the bottom reservoir A', as
Been in Fig. 2, or may contain the bottom reservoir A¹, as seen in Figs. 4 and 5.
A is the top reservoir, and these two reservoirs A' and A' are connected together
by the pipes or columus technically called "loops" B. These loops B may be
formed with steam or water passages B₁ and air passages B2, as seen in Figs. 2
and 3; or they may have the steam or water passage B¹ alone, and may be of
straight or looped form, as seen in Figs. 4 and 5 respectively. The top reservoir A
is preferably enclosed within a perforated ornamental top A³, and a perforated
ornamental cover A' is provided to the base A. This cover A is preferably made
in two parts longitudinally, so that the front half, or back half, may be removed,
in order to readily get at the connections between the loops and the reservoirs,
when desired.
The reservoirs are formed with taper openings corresponding in number to the
number of loops it is intended to employ, and the inner faces of these openings
are turned perfectly true, to receive hollow, conical, internally-threaded gun metal
plugs C.
The cover A rests upon and is secured to a plate D, which has openings therein
corresponding to the steam and air passages B' B₁ of the loops B, and may be
supported by clips or straps D' secured to the top of the reservoir A, as seen in
Fig. 2.
The top A', which is made in two parts, as shewn, also rests on a corre-
sponding plate D, to which the top reservoir A' may also be secured by straps D'
or other device.
The loops B merely rest against and form a butt joint with these plates D,
suitable packing being provided to make a tight joint round the steam
passages B. The loops B are secured in position by means of the nipples E,
which consist of a piece of flanged pipe threaded in opposite directions at opposite
ends, the two threads being separated by an annular flange, as will be seen at
Fig. 6.
One end of this nipple E is inserted, from the inside, through the central hole
of the plate D, and into the passage B₁ of the loop, which is tapped to receive
it, and the other end of the nipple is inserted into the tapped plug C. On
turning the nipple with a spanner, the loop B is drawn down onto the packing
of the plate D, which will be nipped between the end of the loop and the flange
of the nipple E, thus making a perfectly steam or water tight joint at that point,
while the plug C is forced down onto its conical seat in the opening of the
reservoir A against the resistance of the clips or straps D' or other device, thus
making a tight joint at that point. The same action will take place with reference

page_text: to the reservoir A², the straps D³ forming the resistance. In order to remove a
loop, it will only be necessary, after removing the several covers, to turn the
nipple E of the particular loop with the spanner in the reverse direction,
when the two nipples will be withdrawn from the particular loop, which can
then be readily removed, and replaced by another, which is then secured as before
described.
In this way the necessity for taking the radiator to pieces, to renew a loop, is
entirely obviated, without any difficulty occurring from loose joints.
The base A may be connected with the external air, as indicated by dotted
lines Fig. 2, so that fresh air may enter & become heated before it passes to the
apartment.
In the form of radiator shewn at Figs. 4 & 5, the resistance devices may consist
of bosses G (see Fig. 5), cast on the reservoirs A' A', and of such a height that
they will meet the plate D, to which the bosses (which are tapped for the purpose)
are secured by screws, or in any other convenient manner.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, declare that what I
claim is :-
1. The mode herein shewn & described of securing the "loops" in radiators,
whereby the double object of ensuring a steam or water-tight joint and of
providing for the easy removal & replacing of a loop, is effected, as set forth.
2. A steam or water radiator constructed and arranged as herein shewn &
described.
