PROVISIONAL SPECIFICATION.
Improvements in Heating and Ventilating Coils.
I, WALTER FARLAN SPENCER, of Cross Bank Works, Oldham, in the County
of Lancaster, Heating and Ventilating Engineer, do hereby declare the nature of
this invention to be as follows:-
This invention relates to the manner in which I construct and arrange heating
and ventilating appliances known as low pressure hot water radiators, and
ventilators, and has for its object to provide for the employment of the same caps
and the same bases, with different shaped and varying forms of coil pipes or tubes,
so that the ornamentation and configuration of such pipes or radiating coils may be
arranged to harmonize with, and suit any existing fittings or suit any order of
architecture, that it may be desirable to conform to. I am also enabled to take the
current of air through my apparatus either with the inlet at the top or the bottom
as may be desired.
In carrying my invention into effect I construct a low pressure hot water
ventilating and heating apparatus in the form of a nest or coil of pipes, connected
to a top and bottom chamber or a top and bottom casing. The shape and
configuration of the upper and lower chambers or water-way boxes I vary, but I
provide upon the inner sides or facing inner ends of each chamber or way box, a
number of bosses or sockets to receive my coil pipes or tubes. These coil pipes or
tubes I make of any desired shape and configuration, their ends being formed in a
manner suitable for entering into, and being corked into the box sockets, such that
when each pipe has been connected at both ends with the box sockets, the whole
apparatus is in effect one piece, held together without the necessity for the
employment of bolts, nuts, cotters, or perishable packing joints.
By this system of removal, and independent top and bottom caps or chambers,
I am enabled to employ any number and any form of coils to contain the water and
to pass the air current through.
The air pipes
pass through the water pipes, the ends of such air pipes being
perfectly secured or caulked into the upper ends of the top water-way box, and into
the lower ends of the bottom water-way box, so that while providing for the free
passage of air through the bottom, or from the bottom to the top, the water cannot
escape into the pipe. The outer pipe or coil I caulk into the water-way boxes in a
manner to allow free passage of the water from one box to another, and from one
pipe or coil to another.
I mount loose gratings at the top and bottom way-boxes for permitting either the
bottom or the top to be used as the inlet aperture according as it may be wished to
bring the air in near the floor, or at a higher position within the room.
I cover
the top gratings or doors with an outer frame or grid, having the air passages
provided for by the peculiar arrangement of ribs or passages, which I form within
the metal plate; the ribs or bars being arranged with view to ensure a large area
of metal in the grid, through which the current of air has to pass. Each section
of the grid or passage, I form as a straight aperture, for the free passage of the
air, the lines or direction of the bars being caused to assume a triangle having &
large number of divisions or straight ports therein. The arrangement or direction
of the ports, within each triangular division, I alter so as to break up the
continuity of flow of the air when passing through the grids, and thus to give up
its heat to the surrounding metal in a well and evenly distributed manner. Similarly

many directions.

COMPLETE SPECIFICATION.
Improvements in Heating and Ventilating Coils.
I, WALTER FARlan Spencer, of Cross Bank Works, Oldham, in the County
of Lancaster, Heating and Ventilating 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 the manner in which I construct and arrange heating
and ventilating appliances, known as low pressure hot water radiators and
ventilators, and has for its object to provide for the employment of the same caps
and the same bases, with different shaped and varying forms of coils, pipes or tubes,
so that the ornamentation and configuration of such pipes or radiating coils may be
arranged to harmonize with and suit any existing fittings or suit any order of
architecture that it may be desirable to conform to. I am also enabled to take the
current of air through my apparatus, either with the inlet at the top or the bottom.
as may be desired.
In the accompanying sheet of explanatory drawings,
Figure 1 is a part sectional and part front elevation of one arrangement of my
improved heating and ventilating coils, and Figure 2 is a plan, one portion of the
plan being sectional on the linear to show the pipes and their attachment to
the base.
In carrying my invention into effect I construct a low pressure hot water
ventilating and heating apparatus in the form of a nest or coil of pipes A A
connected to a top and bottom chamber or a top and bottom casing. The shape
and configuration of the upper chamber B and lower chamber C or water way
boxes 1 vary, but I provide upon the inner sides, or facing inner ends of each
chamber or way box a number of bosses or socket bc to receive my coil pipes or
tubes A.
These coil pipes or tubes A I make of any desired shape and configuration, but
preferably with a large heating surface provided for by means of oval and ribbed
sections as shown at A A' A, their ends a being formed in a manner suitable for
entering into and being caulked into the box socket be such that when each pipe
has been connected to both ends with the box sockets, the whole apparatus is in
effect one piece, held together without the necessity for the employment of bolts,
nuts, cotters or perishable packing joints.
By this system of removal and independent top and bottom caps or chambers, I
am enabled to employ any number and any form of coils to contain the water and
to pass the air current through.
The air pipes D I pass through the water pipes A, the ends of such air
pipes being perfectly secured or caulked into the upper ends 6' of the top water
way box, and into the lower ends c¹ of the bottom water way box, so that while
providing for the free passage of air through the bottom, or from the bottom to the
top, the water cannot escape into the pipe. The outer pipe or coil A I caulk into
the water way boxes in a manner to allow free passage of the water from one box
to another, and from one pipe or coil to another.
I mount loose gratings E F at the top and bottom way boxes for permitting
either the bottom or the top to be used as the inlet aperture according as it may be
wished to bring the air in near the floor, or at a higher position within the room.
1 cover the gratings or doors with an outer frame or grid & having the air passages

page_text: provided for by the peculiar arrangement of ribs or passages gl g³ which I form
within the metal plate; the ribs or bars being arranged with a view to ensure a
large area of metal in the grid, through which the current of air has to pass.
Each section of the grid or passage g¹ g₁ I form as a straight aperture, for the free
passage of the air, the lines or direction of the bars being caused to assume a
triangle having a large number of divisions or straight ports therein. The
arrangement or direction of the ports within each triangular division I alter so as
to break up the continuity of flow of the air when passing through the grids, and
thus to give up its heat to the surrounding metal in a well and evenly distributed
manner. Similarly I cause the entering current to be broken up by being led
through the grids in many directions.
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 :-
1. The construction and arrangement of heating and ventilating coils in which
separate or independent upper and lower water and air way boxes are employed and
in which communicating coils are secured, substantially as and for the purposes
hereinbefore described and as illustrated in the accompanying drawings.
2. The construction of heating and ventilating coils having water way boxes
arranged to receive coils or pipes by caulking externally as at a, b, and also to
secure air pipes by caulking as at b c substantially as hereinbefore described and
illustrated in the accompanying drawings.
3. In heating and ventilating coils the construction and arrangement of grids for
inlet or outlet purposes having triangularly arranged passes or apertures formed
by a number of divisions or straight ports substantially as and for the purposes
hereinbefore described and as illustrated in Figure 2 of the accompanying
drawings.
