Sadiron.
I, WILLIAM E. HOYT, of No. 173, World Building, New York City, in the
County of New York, and State of New York, United States of America, Manu-
facturer, 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:-
My invention relates to improvements in sad-irons; and one object of my in-
vention is to provide a sad-iron which will embody within itself a chamber which
will diffuse the heat properly to the iron, which will remain heated for a long
period.
Another object of my invention is to provide a self-heating sad-iron which will
embody a fluting device which will not render the iron cumbersome or incon-
venient to handle and which fluting device will be thoroughly practical.
Another object of my invention is to provide a self-heating sad-iron in which
the air to support combustion of the fuel contained in the iron is supplied from
beneath at practically all points of the base and to provide means whereby the
draft can be regulated by rotating the handle of the iron.
Another object of my invention is to provide a simple, practical and durable
iron which can be produced at a moderate cost.
I accomplish the object of the invention by the mechanism illustrated in the
accompanying drawing in which―
Figure 1 is a view in perspective of my sad-iron; Figure 2 a vertical longi-
tudinal sectional view thereof; Figure 3 a transverse sectional view of the iron
on the line 3, 3, of Fig. 2; Figure 4 a side view of the iron with the stationary
fluting-plate applied and Figure 5 a perspective view of the fluting devices in
operative positions to clearly show their manner of use.
Similar letters of reference indicate like parts throughout the several views of
the drawings;
A represents the lower part or body of the iron which is of usual shape or
form and is made hollow to form a chamber A¹, having at one end the guides
formed by a single outer flange A2 at each side, against which is fitted and slides
the door or gate B, having the handle 64, and air openings 62 near the top edge of
the gate.
C is the top or cover of the iron and has an underside flange c, inside from the
edge of the top a distance equal to the thickness of the walls of the body A. This
top C has the chimney C¹ and the upwardly projected arm C2 at the end opposite
the chimney, D is a rod passing through the chimney and through the arm C2.
D is a plate mounted on the rod D, inside of the chimney and rotating with the
rod. When in a horizontal position this plate closes the opening in the chimney
and shuts off the draft. It can be turned to the vertical position shown by the
dotted lines or any intermediate position and in fact forms a damper whereby the
air admission can be regulated. E, is a handle which is mounted on the rod D
between the chimney and the arm and F is a plate to deflect the heat and protect
the hand of the operator.

page_text: The handle E can be rotated but in so doing the rod also is rotated which of
course changes the position of the damper. The rod D is projected through the
arm C and on its end is an indicator G which engages a notched sector g. Preferably
the indicator will have a slight spring action which will enable it to be moved
from one notch to another by the exertion of sufficient force but will also prevent
the too free movement of the handle and damper. The indicator will be set with
relation to the plate D₁ to indicate the position of the damper at all times.
H is an inside shell or lining for the combustion chamber separated from the
wall of the top C. The space b, thus provided between the parts A and H forms
an air passage. The walls of the body A are provided with the openings a³, close
to the top of said walls through which air is admitted to the space , and the
bottom of the shell is provided with the inwardly projected base flues h, at
intervals along both sides of the chamber, through which the air in the space b
is discharged into the chamber.
The rear end of the shell is provided with the integral inwardly sloping trans-
verse plate which extends from one wall to the other of the shell and forms a
large end base-flue J through which air can be admitted in large quantities by
raising the gate B, but through which no air is admitted when the gate is down.
To heat the iron, fuel is placed on the base flues h¹plate J and bottom of the
chamber and is ignited. By raising the gate which may be held open by resting
it on the top of the plate J, the reciprocating movement of the iron will draw the
air into the chamber and cause quick combustion and after a good bed of live
coals is secured the draft can be shut off by closing the gate and the damper in
the chimney. The fire can then be kept just right by turning the handle, and
without the operator taking his hands off of his iron or stopping his work.
I provide in connection with my iron, fluting devices which consist of the
separate handle M, to which is connected the curved fluting plate m, which
operates in connection with the fluting-plate N, which plate N is secured to the
side of the iron. When the iron is turned on its side for fluting the ashes and
coals are kept from falling out through the chimney by closing the damper plate.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. The herein described sad-iron having the hollow body or chamber with per-
forated side-walls, the top resting on the side walls of the chamber and having an
under side flange which fits inside of the walls of the body portion, and having
a chimney for carrying off the products of combustion, a shell comprising vertical
walls separated by the flange from the walls of the body and having inwardly
projected base-flues and an integral inwardly sloping plate at its rear end con-
necting the sides of the shell, and a sliding or movable door or gate in one end
of the iron adapted to be tilted inward to rest upon the inclined plate of the shell,
to allow the air to be fed through the rear-end of the iron as well as through the
base flues of the sides, as and for the purposes specified.
2. The combination with a sad-iron having a hollow combustion chamber and
a flue for the escape of the products of combustion, of a handle mounted on a rod
supported by the iron and extending through the flue, and a damper mounted on
the rod within the flue and changed in its position by rotating the handle sub-
stantially as specified.
3. The combination with a sad-iron having a hollow combustion chamber and a
flue for the escape of the products of combustion, of a handle mounted on a rod
supported by the iron and extending through the flue, and a damper mounted on
the rod within the flue and changed in its position by rotating the handle, and
an indicator on the handle rod working in a notched segment to show the position
of the damper and prevent its too free action, substantially as specified.
4. The herein described sad-iron having the hollow body or chamber with per-
forated side-walls, the top resting on the side walls of the chamber and having

page_text: an under side flange which fits inside of the walls of the body portion, and having
a chimney for carrying off the products of combustion, a shell comprising vertical
walls separated by the flange from the walls of the body and having inwardly
projected base-flues and an integral inwardly sloping plate at its rear end con-
necting the sides of the shell, and a sliding or movable door or gate in one end
of the iron adopted to be tilted inward to rest upon the inclined plate of the shell,
to allow the air to be fed through the rear-end of the iron as well as the base flues
of the sides, and a damper mounted on a rod within the flue and changed in its
position by rotating the handle substantially as specified.
