JOHN B. PASCHE, OF SNYDER, TEXAS, ASSIGNOR TO C. M. MITCHELL, OF SNYDER,
TEXAS.
STOVEPIPE-DRUM.979,400.
Specification of Letters Patent. Patented Dec. 20, 1910.
Application filed May 12, 1910. Serial No. 560,895.To all whom it may concern:
Be it known that I, JOHN B. PAscIIE, a
citizen of the United States, residing at
Snyder, in the county of Scurry, State of
5 Texas, have invented' certain new and use-
ful Improvements in Stovepipe - Drums;
and I do hereby declare the following to be
a full, clear, and exact description of the in-
vention, such as will enable others skilled in
10 the art to which it appertains to make and
use the same.
This invention relates to stove pipe drums
and its principal object is to improve the
general construction of devices of this char-
15 acter so that they may be both readily
cleaned and that the temperature of the in-
ner drum may be regulated.
With the above and other objects in view,
the invention consists in general of a device
20 of this kind including an inner drum, an
outer drum and certain other features of
novel and improved construction.
The invention further consists in certain
novel details of construction and combina-
25 tions of parts hereinafter fully described,
illustrated in the accompanying drawings,
and specifically set forth in the claims.
In the accompanying drawings, like char-
acters of reference indicate like parts in the
30 several views, and:-Figure 1 is a longitudi-
nal section through a drum constructed in
accordance with this invention. Fig. 2 is a
view of the back end of such a drum. Fig.
3 is a view of the front end of the drum, the
5 door being open and partially broken away.
The invention consists in an outer drum
10 having a fixed back head 11 secured
thereto and this back head is provided with
a series of slots 12 adjacent its periphery.
At 13 is an inner drum which is provided
with a back head 14, this back head being
spaced slightly from the back head 11. In
order to hold these two heads in proper re-
lation there is provided a centrally disposed
bolt 15 and on this bolt is pivoted a damper
plate 16, the plate thus being held between
the two back heads 11 and 14. The plate 16
is provided with a series of slots 17 similar
to the slots in the back head of the outer
end and adapted to register with said slots
when the plate is rotated to the proper posi-
tion. In order to rotate this plate the latter
has secured thereto a finger grip 18 which
rojects through one of the slots 12, the
pecific slot being provided with recessedportions 19 at the ends to permit the full
movement of the plate 16. By means of this
finger grip the plate 16 may be rotated on
its pivot so that the slots 12 may be opened
to any desired degree. 60
The space between the front ends of the'
drums 10 and 13 is closed by means of a
permanent annular closure 20, this closure
being imperforate. Secured to the closure
20 by means of a hinge 21 is a door 22 which 65
serves to close the front end of the inner
drum. Adjacent one side of this door, pref-
erably directly opposite the hinge 21, is a
turn button 23 which is adapted to engage
a keeper 24 so that the door, when closed, 70
may be held in closed position.
Oppositely disposed stove pipe connec-
tions 25 are provided in the outer drum and
it is preferred that these connections be ar-
ranged vertically with respect to each other 75
so that the hot gases rising through the
lower of the connections will pass evenly
around both sides of the inner drum and out
of the upper connection 25.
By means of the damper plate 16 the 80
temperature of the inner drum may be regu-
lated, the slots 12 being opened when it is
desired to cool the inner drum and closed
when it is desired to have the inner drum
as hot as possible. Furthermore, when the 85
slots are fully opened a small scraper may
be employed to draw the accumulated soot
out of the drum or to push it down through
the lower stove pipe connection, as may be
desired. 90
There has thus been provided a simple and
efficient device of the kind described and
for the purpose specified.
Having thus described the invention, what
is claimed as new, is:- 95
1. In a device of the kind described, an
outer drum having a fixed back head pro-
vided with a series of slots adjacent its pe-
riphery, an inner drum having a back head
slightly spaced from the back head of the 100
outer drum, a. centrally disposed bolt con-
necting said heads, a. damper plate pivoted
on said bolt and having a series of slots simi-
lar to the slots in the back head of the outer
drum and adapted to register therewith, and 105
means projecting through the outer drum
to rotate said damper on its pivot.
2. In a device of the kind described, an
outer drum having a fixed back head pro-
vided with a series of slots adjacent its pe- 110
