Abstract
Abstract The pressing iron of this invention has a detachable, throwaway sole plate of hollow, evacuated glass which contains an infrared heating element. The entire wiring means for the unit is contained within the iron handle and the sole plate is operatively wired to the handle by plug-in, male/female terminals. The handle and sole plate are held together by simple means such as clamping and/or bolting to allow ease of changing units. An important optional feature is an ultraviolet lamp unit molded as an integral part of the sole plate bottom. The ultraviolet lamp is also connected to wiring in the handle by plug-in male/female terminals and is wired in parallel with the infrared unit. The ultraviolet unit is hand triggered and, as a safety measure, a mercury switch in the circuit automatically shuts the ultraviolet unit off when the iron is upright. The sole plate is easily changed by simply unclamping or unscrewing the sole plate, unplugging it from the handle wiring, and reinserting the new unit.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
146 words
A pressing iron comprising: a. a detachable, disposable sole plate, said sole plate including a molded, hollow, evacuated glass shell having a generally flat bottom portion to engage the material to be pressed and generally curving upward therefrom to form an upper portion shaped to mate with a handle; b. an infrared heating element disposed within said hollow shell operatively connected to a power source through a terminal mounted within said shell wall proximate said upper shell portion, said terminal means and said shell wall forming together a continuous, integral, sealed sole plate unit; c. a handle removably engaged with said sole plate; d. wiring means disposed within said handle and adapted to connect with a power source at one terminal and to mate with the infrared heating element at the other terminal; and e. fastening means to hold together said handle and said sole plate.
Claim 2
Dependent Claim
146 words
A pressing iron comprising: a. a detachable, disposable sole plate, said sole plate including a molded, hollow, evacuated glass shell having a generally flat bottom portion to engage the material to be pressed and generally curving upward therefrom to form an upper portion shaped to mate with a handle; b. an infrared heating element disposed within said hollow shell operatively connected to a power source through a terminal mounted within said shell wall proximate said upper shell portion, said terminal means and said shell wall forming together a continuous, integral, sealed sole plate unit; c. a handle removably engaged with said sole plate; d. wiring means disposed within said handle and adapted to connect with a power source at one terminal and to mate with the infrared heating element at the other terminal; and e. fastening means to hold together said handle and said sole plate.
Claim 3
Dependent Claim
60 words
A pressing iron according to claim 1 further comprising: f. an ultraviolet ray lamp embedded within the flattened lower shell portion of said glass sole plate wall, operatively connected to a power source through the upper shell portion terminals by wiring means located within said handle to provide thereby a source of disinfecting radiation directable to the material being pressed.
Claim 4
Dependent Claim
58 words
A pressing iron according to claim 2 in which the flatteneD shell bottom portion has a cross section generally shaped like an isosceles triangle wherein the matching sides are convex and wherein said ultraviolet ray lamp is tubular in design and is disposed in the perimeter of the convex sides in a plane parallel to said flattened bottom.
Claim 5
Dependent Claim
70 words
A pressing iron according to claim 2 in which the flattened shell bottom portion has a cross section generally shaped like an isosceles triangle wherein the matching sides are convex and wherein said ultraviolet ray lamp is tubular in design and is disposed in a plane parallel to said flattened bottom, extending in a straight line from a point bisecting the triangle''s base to the angle at the triangle''s apex.
Claim 6
Dependent Claim
136 words
A pressing iron according to claim 1 in which the flattened shell bottom portion has a cross section generally shaped like an isosceles triangle wherein the matching sides are convex and in which said fastening means comprises: a. A first bracket extension depending from said handle extending along the sole plate shell wall to, and under, the nose point of the sole plate to form a flange; b. a spring mounted at one of its ends on the first bracket, on its other end adapted to secure said first bracket flange against said sole plate bottom; c. a second bracket extension depending from said handle extending along the sole plate back; d. an L-shaped bracket terminating at one end in a lip adapted to secure the second bracket extension against the sole plate side and bottom.
Claim 7
Dependent Claim
22 words
A pressing iron according to claim 2 in which the wiring means for the ultraviolet and the infrared are connected in parallel.
Claim 8
Dependent Claim
21 words
A pressing iron according to claim 1 wherein the sole plate is operatively connected to the handle by male/female terminal connectors.
Claim 9
Dependent Claim
21 words
A pressing iron according to claim 2 wherein the sole plate is operatively connected to the handle by male/female terminal connectors.
Claim 10
Dependent Claim
14 words
A pressing iron according to claim 2 wherein the ultraviolet element is finger triggered.
Claim 11
Dependent Claim
28 words
A pressing iron according to claim 2 wherein the wiring means for the ultraviolet element includes a mercury switch adapted to automatically open when the iron is upright.
