Improvements in and relating to Sad Irons.
We, WILBERT W. LAMB, PETER G. KRAEMER, and GEORGE A. LAMB, all of
Des Moines, State of Iowa, United States of America, Capitalists, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
The object of this invention is to provide improved means for heating a
sad iron and maintaining the same at a heated temperature.
A further object of my invention is to provide a sufficient supply of air to
the flame chamber of a sad iron to insure perfect combustion therein of the
heat-supplying medium.
A further object of my invention is to provide means to insure the perfect
vaporization of the fluid employed as the heating medium in advance of the
burning thereof in the flame chamber of the sad iron.
A further object of my invention is to provide improved means for attaching
a cover and handle to a sad iron in such a manner as that said cover and handle
may be removed and replaced readily and conveniently.
My invention consists in the construction, arrangement and combination of
elements hereinafter set forth, pointed out in my claims and illustrated by the
accompanying drawings, in which
Figure 1 is a side elevation of the complete device. Figure 2 is a vertical
section of the device longitudinally of Figure 1. Figure 3 is a plan of the
device, the cover and liquid tank being removed. Figure 4 is a rear end elevation
of the device. Figure 5 is a cross section of the device on the indicated line 5-5
of Figure 1. Figure 6 is an enlarged detail section of the generator.
In the construction of the device as shown the numeral 10 designates the
base formed with an interior flame chamber 11, the side and end walls of the base
rising from and at right angles to the bottom, thus providing a flame chamber
of great capacity relative to the exterior dimensions of the base. The rear end
wall of the base 10 is formed with a notch 12 in the center thereof and opening
to its top. A generator 13 is provided and formed with notches in vertical
planes on opposite sides, which generator is seated in the notch 12 of the rear
end wall of the base 10 and the notches thereof engage and receive the edges of
said end wall. The generator 13 is formed with a horizontally-disposed trap
chamber 14 in its forward end portion and a supply pipe 15 is screwed into said
trap chamber. The supply pipe is flexed laterally within and extends longi-
tudinally of the upper portion of the flame chamber 11 of the base 10 forming a
sinuous passage for the fluid in the flame chamber. The supply pipe 15 extends
outward from the flame chamber through a notch 16 formed at the point of con-
vergence of the forward ends of the side walls of the base 10 and a horizontal
coil 17 is formed in said pipe in front of the base. The supply pipe 15 rises
from the horizontal coil 17 and is screwed at its upper end into the lower end of
a supply tank 18 arranged and so shaped as to be supplied with gasoline or

page_text: similar liquid and furnish said liquid to the pipe. The supply tank 18 is pro-
vided with an opening or mouth at its upper end and a screw plug 19 is fitted in
said opening or mouth and seals the liquid against escape from the tank by
evaporation. The generator 13 is formed with a vertically-disposed well 20 in
its rear portion, which well is drilled in the generator from the top and normally
closed by a screw plug 21 seated in the upper end thereof. The generator 13
also is formed with a horizontally-disposed communicating passage 22, of minute
diameter, leading from the upper end of the trap chamber 14 to the upper portion
of the well 20. The lower portion of the generator extends rearwardly from the
vertical plane of the well 20 and is horizontally bored, the forward end portion
of the bore being tapered or reduced to a minute port, the said bore com-
municating with the lower end of the well. A burner 23 is mounted horizontally
in the forward portion of the generator 13 below and parallel with the supply
pipe 15 and extends longitudinally of the lower portion of the flame chamber 11
in the base 10 and the forward end of the burner is closed. The burner 23 is
mounted in alinement with the bore of the lower rear portion of the generator 13
and receives vapor therefrom and said burner is formed with three rows of per-
forations 24 throughout its length and in the lower portion thereof. One row
of the perforations 24 opens downwardly from the burner 23 and the other rows
of perforations are located on either side of the said row and open toward the
bottom of the flame chamber and at oblique angles to the first. A notch 25 is
formed in the lower portion of the generator 13 between the forward end
of the lower bore and the rear end of the burner 23 and a drip cup 26 is formed
in a rearwardly-projecting portion of the base 10 immediately below said notch.
A needle valve 27 is screwed in the bore at and transversely of the lower end of
the well 20 and the forward end of said needle valve is cone shaped and fits in
and against the forward portion of said bore and cuts off, at time, the flow from
said bore. A stuffing box 28 is mounted on the rearwardly-projecting portion
of the generator 13 concentric with the needle valve 27 and a packing 29 of
asbestos or similar suitable material is located in the stuffing box and surrounds
and contacts with the valve. The needle valve 27 extends rearwardly from
the stuffing box 28 and is made angular for engagement by a wrench or key (not
shown) of common form whereby said valve may be rotated. Ventilating
pipes 30, 31 are mounted in and longitudinally of the lower side corners of the
flame chamber 11 and extend through the rear end wall and the forward end
portions of the side walls of the base 10. The ventilating pipe 30, 31 are open
ended and rigidly mounted in the base and are formed with upwardly-opening
ports 32 in rows throughout their lengths and in the top portions thereof. The
upper margins of the intermediate portions of the side walls of the base 10 are
cut away and notched below the horizontal plane of the top of the forward ends
thereof to provide space for the escape freely of the air from the flame chamber 11.
Ventilating ports 33, 34 are formed in the lower portions of the side walls of
the base 10, which ports are inclined, entering the side walls below the tops of
the ventilating pipes 30, 31 traversing said walls obliquely upwardly and enter-
ing the flame chamber 11 in the plane of or above the said pipes, the inner
openings of the ports being wholly above the outer openings thereof. By
reason of the inclined positioning of the ports 33, 34, the atmospheric air must
enter the flame chamber in an upwardly oblique direction and direct the escape
of the air from the flame chamber through the notches and spaces at the tops
of the side walls of the base. Holes 35, 36 are formed in the upper portions of
the rear end wall of the base 10 and a cover 37 is formed with rearwardly-pro-
jecting pins on its rear end entering said holes. The cover 37 extends over the
flame chamber 11 and the forward extremity thereof enter the converging space
between the converging forward ends of the side walls and is retained by a
hook 38 pivotally mounted in a vertical aperture or seat in one of the side walls
and adapted to be turned manually to engage above the cover. A stud 39 is
formed on and extends downwardly from the rear end of the lid 37 and engages

page_text: the upper face of the generator 13, and thus the generator is held against upward
movement from its seat in the base 10. Standards 40, 41 are formed on and rise
from the ends of the cover 37 and a handle 42 connects the upper ends of said
standards. A shield 43 is mounted between the handle 42 and the cover 37,
whereby the hand of the operator is protected from the heat of the said iron.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that
what we claim is:-
