[Communicated from abroad by THE PROPRIETORS OF THE COPENHAGEN HORSE-SHOE
MANUFACTORY, of Copenhagen, in the Kingdom of Denmark.]
Improvements in Furnaces Chiefly Designed for Use in the
Manufacture of Horse-shoes.
1. HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co., Patent Agents
45, Southampton Buildings, in the County of Middlesex, do hereby declare the nature of
this invention to be as follows :-
This invention relates to furnaces for use in the manufacture of small articles.
The furnace which forms the subject of the present invention and which is especially
intended for use in the manufacture of horse-shoes by machinery, is based upon the
automatic feeding of the objects intended to be heated.
The furnace which is built of bricks, has an opening for firing, through which fuel
according to the requirements is passed down into the fire place. The firing opening
is in connection with a space for filling in the fuel and is always closed by the said
fuel. The fire place has at the bottom, slanting fire bars, which can be cleaned
through an aperture.
The air necessary for the combustion is conveyed through a blower tube, and passes
from thence up through the fire bars and the fuel. The flame and the products of
combustion pass through a heating chamber into the chimney.
The articles which are to be heated are laid side by side in trough-shaped boxes
and are conveyed into the oven through an aperture in the side. The box is then
turned upside down and the articles slide down an incline into the heating chamber
and are taken out red hot through an opening on the opposite side.
The principal advantages of the improved furnace is that the objects are heated
while on the incline, and also that they, by their own weight, slide down the incline
and become red hot by degrees, as the space will allow, so that the man who attends
the furnace, is only required to fill in at the feeding aperture, in order that the man,
who looks after the next operation in the manufacture, can take the red hot articles
out at the opening at the opposite side.

I, HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co., Patent Agents
Southampton Buildings, in the County of Middlesex 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 furnaces for use in the manufacture of small articles.
The furnace which forms the subject of the present invention, and which is
especially intended for use in the manufacture of horse-shoes by machinery, comprises
means for automatically feeding the objects intended to be heated into the said
furnace.

page_text: The furnace which is built of bricks is provided with an opening a through which
fuel, according to the requirements, is passed down into the fire-place 6. The firing
opening is in connection with a hopper for filling in the fuel and the said opening a
is always closed by the said fuel being piled up against the same. The fire-place
is provided at the bottom with slanting fire-bars & which can be cleaned through an
aperture f
The air, necessary for the combustion, is conveyed through a blower-tube g, and
passes from thence up through the fire-bars and the fuel. The flame and the products
of combustion pass through a heating chamber h into the chimney i. The articles
which are to be heated are laid side by side in trough-shaped boxes and are conveyed
into the oven through an aperture k in the side. The box is then turned upside
down and the articles slide down an incline into the heating chamber and are
taken out red hot through an opening n on the opposite side.
The principal advantages of the improved furnace are that the articles are heated
while on the incline . And also that they, by their own weight, slide down the
incline and become red hot by degrees, as the space will allow, so that one attendant
is only required to fill in at the feeding aperture K in order that another attendant
who looks after the next operation in the manufacture, can take the red hot articles
out at the opening n on the opposite side.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed as communicated to me by
my foreign correspondents, I wish it understood that I claim :—
The improved heating furnace for use in the manufacture of small articles, provided
with means for automatically feeding the said articles into the furnace, all' as above
described and shown in the accompanying drawing.
