Comp.ete Specification Left, 3rd Mar., 1897-Accepted, 3rd Apr., 1897
PROVISIONAL SPECIFICATION.
Improved Means for Arresting the Exit of Sparks from Engine
Funnels.
I, EDGAR JEFFERSON SOLOMON, of Carlinville, Ill., U.S.A., Inventor, do
hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide simple means whereby sparks are
prevented from escaping from engine funnels, whereby the liability of conflagration
is avoided.
The invention consists in connecting the exhaust pipe, in the lower part of the
usual smoke box, with the funnel at the upper part thereof, by means of a
cylinder having a number of incisions made in its surface in such manner the
a tongue, which is formed by the shape of said incisions, is capable of being pressed
inwards thereby partially closing the opening thus formed.
It will be understood that the sparks entering the openings are arrested by the
tongues.
Dated this 29th day of June 1896.

Improved Means for Arresting the Exit of Sparks from Engine
Funnels.
I, EDGAR JEFFERSON SOLOMON, of Carlinville, Ill., U.S.A., Inventor, 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:-
The object of my invention is to provide a simple and efficient device for
attachment to a locomotive, for preventing the escape to the smoke stack of
sparks and cinders, while permitting of the free escape of the products of
combustion.
The invention consists in the construction hereinafter described and claimed.
Reference is to be had to the accompanying drawings, forming a part of this
specification, in which similar characters of reference indicate corresponding parts
in both views.
Figure 1 is a sectional end elevation of a locomotive boiler; shewing the
application of my improvement; and Fig. 2 is a longitudinal section of the
attachment.
The locomotive boiler A is provided with a smoke box B, exhaust nozzle C and
smoke-stack D of usual description; to the exhaust nozzle C is fitted the lower
end of the tube E, which in the present case is conical in form. The tube E may
be fitted in any convenient way to the nozzle. I have shewn a simple and

page_text: practical device for this purpose, which consists of a ring a fitted to the tube, and
set screws b passing through the ring and the tube and bearing upon the sides of
the exhaust nozzle. The upper and large end of the tube E fits into the lower
end of the smoke stack D and in the sides of the tube E are made U-shaped slits c,
leaving a tongue of metal d, which in each case is pressed inwardly, as shewn in
Fig. 2, thereby leaving sufficient space between the tongue and the wall of the
tube for the escape of the products of combustion, the slits c are in all sides of
the tube E, and the combined area of all the openings made by pressing in the
tongues d is sufficient for the ready escape of all the products of combustion.
The exhaust in passing through the tube E creates a draft in the well known
manner and draws all the products of combustion to the tube E through which
the gaseous portions escape to the smoke stack, while the solid portions, striking
the tongues d are thrown back into the smoke box, where they remain until the
smoke box is cleaned.
The tube E may be made of any form to adapt it to the particular locomotive
to which it is applied but the conical form here shewn will be found applicable in
most cases. It may also be made of any suitable material, such as sheet iron, steel,
or copper.
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.) A spark arrester consisting of a tube having a series of elongated openings
and a tongue projecting from the upper edge of every opening, substantially as
set forth.
(2.) A spark arrester, comprising a tapering tube formed with a series of
elongated openings and a tongue projecting from the upper edge of every opening
inwardly and downwardly towards the lower smaller end of the tube substantially
as described.
