CASPER F. LOCHNER, OF JEFFERSON, ASSIGNOR TO HIMSELF, DANIEL R.
MURPHY, OF MARSHALL, AND W. P. TORRANS, OF JEFFERSON, TEXAS.
IMPROVEMENT IN SPARK-ARRESTERS.
Specification forming part of Letters Patent No. 217,542, dated July 15, 1879; application filed
February 15, 1879.
To all whom it may concern:
Be it known that I, CASPER F. LOCHNEl,
of Jefferson, Marion county, Texas, have in-
vented a Cone and Spark-Arrester, of which
the following is a specification.
The object of my invention is to improve the
construction of spark-arresters, so that they
will be more efficient, and yet simple in con-
struction and not liable to get out of repair;
and the invention consists of a metallic circu-
lar cone, with winding or arched flanges or
wings, which extend toward the side of the
shell, and they are covered by a plate, to the
upper side of which a perforated cylinder is
attached, so that all the sparks are arrested
and thoroughly extinguished, while the smoke
can pass out through the perforations, all of
which will be more fully described hereinafter,
reference being had to the accompanying
drawings and letters of reference thereon, in
Figure 1 is a central vertical section of my
spark-arrester. Fig. 2 is a plan view of the
plate with the arched wings. Fig. 3 is a side
view of the same.
In the drawings, A represents the shell of
a smoke-stack for locomotives, in the upper
flaring part of which is arranged a circular
plate, B, to which the arched or curved wings
or flanges C are attached. This plate is sup-
ported upon standards D, connected to the
lower part of the stack.
Above the plate B is arranged a cylindrical
perforated piece of metal, E, secured to the
upturned flange e or mouth or neck of the
It will be readily understood that the sparks,
ascending by the force of the exhaust-steam
and the draft of the chimney, receive a whirl-
ing or circular motion by coming in contact
with the plate and curved wings, and fall back
into the smoke -arch, while the smoke. can
freely pass out through the perforations. The
sparks are also entirely extinguished, and can
be removed from the smoke when desired.
The advantage of my spark-arrester is, that
it is very simple in construction, and not liable
to get out of order; it can be easily repaired; it
can be readily applied .to any smoke-stack
having a flaring part; the sparks are entirely
extinguished and prevented from passing out,
and the smoke is not at all impaired.
Having thus described my invention, what
I claim, and desire to secure by Letters Pat-
1. In a spark-arrester, the circular plate B,
provided with curved flanges or wings C, and
supported on standards D, constructed and
arranged as shown and described.
2. The combination of the shell A with the
circular plate B, provided with curved wings
C, supported on standards D, and the perfo-
rated piece E, secured to the mouth of the
stack, all arranged substantially as shown,
and for the purpose specified.
