Year: 1877

page_text: LETTERS PATENT to William Byram, in the Employment of Walton and Brear,
of Bradford, in the County of York, Plumbers and Gas Fitters, for the
Invention of "IMPROVEMENTS IN THE CONSTRUCTION OF PIPES EMPLOYED IN
HEATING AND VENTILATING ROOMS AND BUILDINGS."
Sealed the 6th October 1877, and dated the 12th April 1877;
PROVISIONAL SPECIFICATION left by the said William Byram at the Office
of the Commissioners of Patents on the 12th April 1877.
WILLIAM BYRAM, in the Employment of Walton and Brear, of Bradford, in the
County of York, Plumbers and Gas Fitters. "IMPROVEMENTS IN THE CON-
STRUCTION OF PIPES EMPLOYED IN HEATING AND VENTILATING ROOMS AND
BUILDINGS."
This Invention has reference to that class of apparatus employed in heating and
ventilating rooms and buildings which are constructed of a number of pipes, and
the improvements consist in making such pipes with one or more longitudinal ribs
or projections, such ribs being either solid or hollow; and if hollow, communicating
with the water or air space in such pipes.
The object of this Invention is to obtain more heating or cooling surface. By
preference the pipes are arranged so that there is not an open clear passage for the
air to pass, the pipes being arranged in rows of odd and even numbers, that is, one
row of pipes is placed over the spaces left between the other row of pipes, so that
the air in its transit around the outside of the said pipes will come directly into
contact with each pipe and its longitudinal rib or projection, by which means I
obtain a much greater heating surface than heretofore.
To facilitate the corking or jointing of the pipes they are made with a socket
projecting beyond the ordinary flange, which sockets are placed in corresponding
holes in a plate, the cement or other suitable material being easily applied and the

page_text: joints made; a loose cover is afterwards put on and secured to the plate to form
the chamber, making the communication of the pipes with each other complete.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by the
said William Byram in the Great Seal Patent Office on the 12th October
1877.

This Invention has reference to that class of apparatus employed in heating and 1
ventilating rooms and buildings which are constructed of a number of pipes, and
the improvements consist in making such pipes with one or more longitudinal ribs
or projections, such ribs being either solid or hollow; and if hollow, communicating
with the water or air space in such pipes.
The object of this invention is to obtain more heating or cooling surface. By 1
preforence the pipes are arranged so that there is not an open clear passage for the
air to pass, the pipes being arranged in rows of odd and even numbers, that is, one
row of pipes is placed over the spaces left by the other row of pipes, so that the air
in its transit around the outside of the said pipes will come directly into contact
with each pipe and its longitudinal ribs or projections, by which means I obtain a
much greater heating surface than heretofore.
To facilitate the caulking or jointing of the pipes they are made with a socket
projecting beyond the ordinary flange, which sockets are placed in corresponding
holes in a plate, the cement or other suitable material being easily applied and the
joints made; a loose cover is afterwards put on and secured to the plate to form the
chamber, making the communication of the pipes with each other complete.
In order that this Invention may be better understood I have herein given
reference to the accompanying Sheet of Drawings illustrative thereof.
Fig. 1 is a cross section, and Fig. 2, a sectional plan of a "coil" or apparatus used
for heating and ventilating rooms or buildings, the general construction being some-
what similar to those in ordinary use.
A are the pipes having wings or projections a. The pipes are arranged in odd
and even numbers, one row of pipes being placed over the spaces left between the
other row of pipes, as will be seen on reference to Fig. 1.
It will also be seen that the wings of the pipes will become as hot as the pipes
themselves, and by the peculiar arrangement of the pipes the air rising from the
bottom of the chamber cannot possibly get to the top without impinging against
either the pipes or the projecting wings, and therefore before the air passes out
again it becomes nearly as hot as the coil.
Instead of the wings or projections a being made solid, as shown in Fig. 1, they
may be made as waterways, as shewn in Fig. 3, or they may be made of various
other shapes, as shewn in Figs. 4, 5, and 6; the wings or projections may also be
made of zig-zag form instead of straight, as shown.
In order to connect the pipes with the water space or chamber a loose plate B,
with holes corresponding to the number of pipes intended to be used, is placed on
the end of the pipes, and the caulking or connecting together is easily accomplished.
On the top of this plate is placed a box or shell C, which forms the waterway or
chamber, water entering in at D from any convenient source and passing out at E.
In small coils an ordinary coil box may be used instead of the plate B and outer
shell C.
Having now described the nature and particulars of my Invention, and shewn

page_text: how the the same may be put into practice, I would have it understood that what I
consider to be new, and therefore claim as my Invention is, the construction of
pipes having either solid or hollow projections or wings a, as and for the purpose
herein shewn and described.
In witness whereof, I, the said William Byram, have hereunto set my hand
and seal, this Sixth day of October, in the year of our Lord One thousand
eight hundred and seventy-seven,
Signed, sealed, and delivered by the
within-named William Byram
in the presence of
THOS. WALTON,
JOSEPH RICHARDSON.
