AN IMPROVED BLOWER OR DRAW-TIN FOR DOMESTIC FIREPLACES
Year: 1884

page_text: I, HERMANN NEUMANN of 45 Cloth Fair in the City of London Engineer do
hereby declare the nature of my said invention for "AN IMPROVED BLOWER OR
DRAW-TIN FOR DOMESTIC FIREPLACES "
to be as follows:-
My Invention relates to an improved blower to be temporarily applied to open
fire grates for the purpose of urging the combustion and my invention has for its
object to enable the blower to be readily adapted to different grates having either
curved or straight bars and when not in use to be stowed away in a comparatively
small compass.
To adapt the blower to be applied to a round fronted grate and to enable it to
be folded up it is made of at least two sheet metal plates hinged together upon the
central vertical line of the blower each plate being furnished with books on the
inner side to engage with the front bar of the grate and each provided with a
pressing screw turning in a nut in the blower and bearing against the grate bars.
whereby the hooks are drawn tight against the said bars and the blowers held.
securely in place whether the bars be curved or straight. The blower may be
round topped or square according to the form of the grate to which it is to be
applied.

page_text: This is effected by so restricting the access of the air to the flue as to compel it
to pass through the fire whereby a strong current or draught is created through
the area of combustion causing a rapid increase of heat and flame.
Hitherto blowers have usually been constructed of cast-iron or sheet iron in one
piece and they are thus bulky and awkward to handle.
Being required only occasionally as when lighting a fire for a few minutes or
when renewing it with fresh fuel after it has burnt low, they have to be removed
shortly after use, and are found cumbersome and inconvenient, and are therefore
avoided by many housekeepers, notwithstanding their great and obvious utility.
My improved blower is constructed of metal plates, hinged together in one or
moro vertical or horizontal lines so as to fold up into a comparatively small space.
They are made of any required shape or size to suit the grate, and may if
preforred be ornamental or ornamented, so as to serve for a grate ornament, when
the fire is not required.
They are furnished with hooks to clip the bars of the grate or may be hung from
small studs or pins fixed in the front of the grate, and adjusting screws may be
used to fix the said hooks to the bars of the grate.
They can also be made adjustable in their effect upon the draught so as to
regulate the supply of air to the fire and cause a slow or brisk draught as
required.
In the accompanying drawings;
Figure 1-is a simple form of folding blower, hinged at the line B. B.
Figure 2-is an arched or dome top blower with adjustable apertures at A. A.
and hinges at B. B.
Figure 3-is a blower of an embossed or ornamental description adapted to serve
as a grate ornament.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is
1. A metal blower for ordinary household fires capable of being folded so as to
occupy a comparatively small space.
2. A folding blower with adjustable hooks and flaps or openings.
3.-A folding adjustable blower which is so ornamented as to serve also the
purpose of a grate ornament.
