Improvements in Stoves or Fireplaces.
We, EDWARD SCANLAN, of No. 201 Twenty-fourth Street and FREDERICK
WENDELL KEIFEL, Jr., of No. 2029 Bank Street Louisville, County of Jefferson and
State of Kentucky and JOHN ZIPP of No. 215 E. Thirteenth Street New Albany,
County of Floyd, State of Indiana, of the United States of America, Manufacturers,
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 certain new and useful improvements in fire places and
grates and it has for its objects among others, to provide simple and efficient means
for operating the upper and lower dampers and for holding the same in their
adjusted positions, the operating rods therefor being slidably mounted so that after
use they may be pushed in out of the way.
The end of the lever or rod which operates the upper damper is rounded so as to
drop the lever on the pintle of the damper to allow the damper to close by its own
weight. The upper damper is pivoted at its upper edge so as to be lifted to open
the same and thus acts to direct the smoke from the front to the rear and up the
chimney so that the smoke and soot cannot escape into the room, avoiding the
necessity of filling in or building up at the top of the grate.
It has for a further object to provide an improved means for holding the lining
in place, the base of the lining being held by a lug and the lining borders or
clamping pieces at the top being self-locking. The roof is provided with lugs
adapted to engage under a cross piece to permit of the body of the workman
through the opening to fill in the back. The central portion of the back is formed
independent of the other portions so as to allow for the necessary expansion and
contraction. The roof, the frame and all the parts are detachably and securely
held together and in position by three lateral bolts. The upper cross-piece is
trough-shaped to hold mortar when it is built up at the top.
Other objects and advantages of the invention will hereafter appear and the
novel features thereof will be particularly pointed out in the appended claims.
The invention is clearly illustrated in the accompanying drawings, which, with
the letters of reference marked thereon form a part of the same and in which
Fig. 1 is a substantially central, vertical section from front to rear.

Like letters of reference refer to like parts in all the figures of the drawing.
Referring now to the details of the drawing by letter, A designates the side
pieces which, at their adjacent rear edges are formed with the apertured lugs A¹
to receive the connecting bolt A provided with the nut a. These lugs are
shouldered as shown at a in Fig. 2 to support a lateral portion of the back and at
the higher point the adjacent edges of these side pieces are formed with lugs A
which are apertured to receive the connecting bolt A' provided with the nuts a³.

page_text: These lugs are formed with the inwardly-extending flanges a³ as seen best in Fig. 2
which receive beneath them the upper lateral portion of the back.
B is the back formed independently of the side pieces and offset as shown at b,
at points near the top and bottom as shown in Figs. 1 and 2 being provided with
the rearwardly-extending lateral portion B₁ resting upon the shoulder a' of the
side pieces and near its upper end with a rearwardly-extending horizontal
portion 12 which is engaged beneath the flanges a³ of the lugs A Above this
lateral portion the back is formed with an inclined portion B³ having openings for
the passage of lugs on the lining clamps or borders, one of such openings 6¹ being
seen in Fig. 1 and in Fig. 2 the lugs of the said borders are shown projecting
through the opening. This back is placed in position between the side pieces and
the whole secured together by the bolt A2 and A' as seen best in Fig. 2.
The base portions of the side and back pieces are formed with upwardly-
extending lugs A as indicated by dotted lines in Figs. 1 and 2 which engage in
corresponding apertures in the lower edges of the portious e, of the lining brick.
The end pieces are formed with lateral offsets and near their front edges are
provided with apertured lugs a to receive the pintles d, projecting from the
grate D and with other lugs a to the rear upon which the rear edge of the grate
is designed to rest. The base portion of the end-pieces are further provided with
the lugs a as seen best in Fig. 3 against which the base portion of the back rests
and by which displacement thereof is prevented. The front edges of the end pieces
are formed near the top and bottom with the lugs a' as seen best in Figs. 2 and 3
to receive the screws or other means which are employed to retain the ornamental
front portions in place. The back being independent of the side pieces and
connected thereto in the manner described is free to expand or contract without
danger of breaking or of distorting any of the other parts.
The upper end of the inclined portions of the side pieces are provided with
lugs as and these portions are connected by the cross-piece C¹ which is trough-
shaped in cross section as seen best in Fig. 1 to hold mortar if required in building
up the top. A rod C2 passed through the openings in the lug a8 and provided
with nuts a serves to bind these parts together as shown.
D' are the clamps or border pieces that bold the upper edges of the lining
section in place; they are formed with lugs d¹ which overlap and conceal the
upper edges of the lining sections and also with lugs which project through
openings in the back and end pieces as seen in Figs. 1, 2, 4, and 5, which lugs are
apertured to receive the locking pins d³ after they have been passed through the
openings in the back and end pieces. These border pieces or clamps are self-
locking as shown in Figs. 8 and 9 so that when all are in position they will be
there retained even if the locking pins are broken. The grate is provided with
an ornamental front E, and beneath this is an ornamental base E having one or
more draft doors or registers e. E is a removable ornamental blower or shield
and E³ is the upper ornamental portion of the front frame piece which is secured in
position by screws engaging in the lugs a' as shown. Fin Fig. 1 designates a
removable summer front which may be as ornamental as desired.
G represents the roof piece or frame which is mounted removably upon the
inclined rear faces of the end pieces; it is provided at its upper edge with the
inclined or under-set lugs g, as seen best in Fig. 1 which engage under the inclined
Hange c, of the trough-shaped upper cross piece as shown best in Fig. 1.
The flange at the lower end of this roof-piece is provided with openings to
receive the lugs of the border pieces as seen best in Fig. 2. When the stop pins
or keys of the lugs of these border pieces are removed the roof piece may be
removed by tilting its lower end upward until the lugs at the upper end thereof
are disengaged from under the inclined flange of the upper cross piece. This roof-
piece or frame is formed near its upper edge at the left hand side with an open
book or bearing H in which is mounted for rotation the pintle H of the upper
damper I while at the other end this roof or frame piece is formed with a loop or
bearing H for the other pintle H³ of said upper damper, these pintles being

page_text: arranged at the upper edge of the damper as shown so that the latter when closed
assumes such position by gravity and when opened it serves to direct the smoke
from the front toward the rear and prevents its escape into the room; it also avoids
the necessity of filling in or building up at the top of the grate. The roof piece
is formed with inwardly-extending flanges 92, upon which the dampers rest when in
their closed position.
The roof piece is formed at the right hand end with an open hook or lug J,
forming a bearing for the pintle J¹ of the lower damper K while at the opposite
end is a bearing J2 for the other pintle J³ of said damper as shown best in Figs. 2, 4,
and 5, the pintles of the lower damper being arranged at the lower edge thereof
as shown. This damper is removable from the inside by simply opening the upper
damper and placing the hand through the opening and lifting the pintles of the
lower damper out of their bearings.
Secured to the right hand pintle of the upper damper is a curved lever L which
is of sufficient length to be engaged by an arm on the push-rod L' which is
mounted to slide through a guide L' and through an opening in the front frame.
The outer end of this rod is provided with an ornamental operating knob or
handle I, as seen in Fig. 4, and at its rear end is provided with a lateral arm L³
which is rounded upon its rear face as seen best in Fig. 2, which is arranged in the
path of the curved lever L as shown and at the rear end it is provided with an
oppositely-extending lug or projection L' as seen in Fig. 2.
To the outer face of the end piece is secured a rack bar L' with which the
arm L on the push-rod is designed to engage to hold the upper damper in any
desired position. When not in use this push rod is designed to be pushed in where
it will be out of the way. When it is desired to operate the damper the rod is
partially rotated so as to bring the arm or lug L³ into a vertical position as shown
in Fig. 3 in which position it is brought forward as far as it can be moved when,
by rotating the rod toward the end piece, the arm or lug L³ will be engaged in
front of the curved lever L when by pushing the rod inward the arm or lug L³ may
be engaged with any notch or tooth of the rack bar and the upper damper will be
held in its adjusted position. When it is desired to close the damper the push rod
may be rotated away from the end piece when the lever will pass between the same
and the edge of the rack bar and the damper will fall to its closed position by
gravity or the rod may be pushed inward until the arm or projection L³ passes the
end of the curved lever L which is being raised as the rod is pushed inward when
the said lever falls and the damper closes. The projection or arm L' serves to
limit the rotation of the push rod and is a guide to the operator in his manipulation
of the push-rod. The lower damper is provided with a lug k, adapted to engage
the lugs on the lower portion of the roof plate or frame to limit the downward
movement of said damper. This damper is provided at one end at a point near its
center with a lateral rod or arm M which is adapted to be engaged by the push-
rod N which is slidingly mounted in a guide N' on the end piece of the frame and
through an opening in the ornamental front frame and at its outer end is provided
with a knob or handle n, by which it may be manipulated.
The inner end of this
push-rod is provided with an open loop n' adapted to engage over the arm M on
the damper as seen in Figs. 1, 2, and 4, and is provided further with a lug n²
adapted to engage the guide N' to limit the outward movement of the push-rod
as shown best in Fig. 1 in dotted lines. This lower damper is mounted to move
inward beyond a perpendicular and is operated by engaging the loop in the push-
rod over the rod M and pushing or pulling the said push-rod to open or close the
damper, the push-rod is rotatably mounted so that it may be turned to engage or
disengage its looped end with the rod on the damper and after opening or closing
the damper the rod may be rotated so as to disengage the loop from the damper-rod
and the push-rod pushed in out of the way; usually however the loop will be
engaged with the rod on the damper when the damper is open; when the damper
is closed and the push-rod in its innermost position and it is desired to open the

page_text: damper the push-rod is pulled out until its lug n² engages the guide N' when the
operator knows that it is in position so that when rotated its loop will engage
the rod on the damper and the latter may be opened by pushing inward upon the
push-rod.
