I, WILLIAM MANN of No. 491 St. Danis Street, City of Montreal District of
Montreal Province of Quebec Canada, Contractor 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 has reference to the construction and arrangement of a furnace for
the purpose of cremating or burning the animal vegetable, or other combustible matter
collected in cleaning the streets &c. of cities, towns, villages &c., or in the general
scavenging of such, the object being to produce a furnace in which such combustible
refuse may be consumed in a less expensive and laborious manner and with a less
amount of noxious vapors or gases being given off to create discase, than in the
furnaces at present in use for this purpose.
The construction will be readily understood on reference to the accompanying
Drawings in which Fig. 1 is a side elevation of a refuse burner embodying my
invention. Fig. 2 is a front end elevation of the burner shown in Fig. 1. Fig. 3 is a
longitudinal vertical section of the said burner, taken on lines a Figs. 2 and 4.
Fig. 4, is a transverse vertical section taken at line x. Fig. 1. Fig. 5 is a transverse
vertical section taken at line y. Fig. 1.
a are furnaces, as shown these are four in number, but a greater or less number
may be used as desired. The furnaces a are provided with, feed openings b, fire bars c,
and ash-pits d having openings e and f. All the openings be and fare provided with
ordinary doors g handi by which they may be closed when desired.
The tops kk, of the furnaces are preferably so arranged that two furnaces are
embraced under one arch k, to give a greater spread to the flames.
1 is a chamber so arranged with regard to the furnaces a that these occupy the lower
part at one end thus forming a space a¹ above the furnace.
The chamber, is provided with fire-bars m, ash pit n opening o p and q each
provided with ordinary doors or s also with opening or flue t, to chimney v.
The operation of the invention is as follows:-
Strong coal fires are formed in the furnaces a. and after the chamber 1, has been
sufficiently heated, the material to be cremated is passed into the chamber by the

page_text: openings o, and by rakes introduced through the openings p distributed upon the
fire bars m; also the ashes accumulating on the bars m may be raked down through
the bars into the ash pits n from which the ashes will be removed by the openings q.
Attention is called to the position of the arches or tops of the furnaces a as being
an important feature in this invention because by forming a space a¹ above them an
eddy is caused, as indicated by the arrow in Fig. 3, by which the gases arising from
the material being cremated, are brought over and over again to be acted upon by the
intense heat at the back end of the furnaces a and are thus more perfectly consumed
before passing by the opening or flue t to the chimney.
A number of chambers provided with furnaces a and otherwise constructed as
above described may be arranged and connected with one chimney v or each chamber
may be provided with a chimney in any ordinary manner, but in any case a liberal
amount of chimney power to form a very active draft should be provided.
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 :-
The combination in a refuse burner of the furnace a consisting of a suitable casing
having suitable inlet and outlet openings o, p, and c; the grate bars m and ash pit n;
the chamber within the casing, the inwardly projecting tops or arches k and flue t,
the whole constructed arranged and operating together substantially as described
for the purposes set forth.
Dated this 12th day of October 1887.
