Flue Caps от Аррlances tо DU ՄՏԵԱ III
Connection with Stove Pipes.
I FREDERICK EDWARD HEINIG residing at Louisville in the County of Jefferson,
and State of Kentucky in the United States of North America, Mechanic 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 invention is described in the following specification, reference being had to the
accompanying drawings forming part of the same.
My invention relates to improvements upon flue caps, which consists in an open
frame and cover with sides of frame bevelling in such a manner that proper bearings
may be moulded therein to allow the doors and bail to work in, also that the doors
and bail may be cast with such projections as will ensure the closing of the doors by
the gravitations of the bail when the stove pipe is removed. I attain these objects by
the mechanism illustrated in the accompanying drawings in which Figure 1 is a front
elevation of my improved cap; Figure 2 is a rear view of the cap showing the form
and manner of hanging the doors and bail. Figure 3 is a perspective view of the cap
with the doors closed. Figure 4 is a perspective view of the cap frame, showing the
door catch and the bearings for door and bail. Figure 5 is a section taken on line 5, 5,
Figure 1.
Figure 6 is a section similar to Figure 5, but showing the doors open.
B is a flue cap frame made of suitable metal shaped with bevelled sides having
bearings B' on the inside corners suitable for the doors D, D, and bail E to hinge
into, and a projection or catch B³, used to hold the doors, when closed.
B is the cover for the frame made with hole to receive the pipe and to hold securely
the doors and the bail in their bearings; D, D, are doors made to swing in the frame
bearings B, and having a raised piece D' on the back of one door that the bail E
comes in contact with it and closes it in advance of the second door, which is made
with a lap D to make a tight joint when closed. E is a bail made to swing in the
bearings B' on frame B and having projections E¹ which hold it in proper position,
when the stove pipe is in place.

page_text: The construction and description of the flue cap is as follows:-The frame B is
made square in form with sides either square or bevelling towards the back and
having bearings B in corners or other suitable places for the doors and bail to work
in the bail and doors are placed in either proper position and the cap B2 is then
fastened on by screws or rivets, which makes the flue cap complete. In putting the
stove pipe in the cap, the doors are raised to pass the projecting catch B³ the pipe
pushes open the doors, thus raising the bail which can be elevated until the projections
on the same come in contact with the frame which bears the bail in such position that
it is impossible to push the end of the stove pipe beyond it, thus securing ample room
in the flue for proper draught. The bail at same time hugs the doors and thus
clamps the stove pipe.
On the removal of the stove pipe, the weight of the bail coming in contact with the
door having a projection on the back, closes it first, then bringing the door with the
lap after it which is forced over the projection or catch on the bottom of the frame,
thus holding the closed doors securely.
I do not confine my invention to any particular shape, as changes may be made in
the form of the different parts and still embody the peculiar character of my
invention.
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. In a flue cap, the combination with the frame, of the cover, the bail having
projections and the doors, substantially as set forth.
2. The combination, in a flue cap, of the frame B, cover B, bail E, with doors D, D,
one of which has a projection D', the other lap D2, substantially as and for the purpose
set forth.
