To this end the the outline of an ordinary flat iron, as is seen 55 upper ends of a forked lever 38, which is pivoted at 45' in notches in the forked front end of a bracket 42 fastened to the hand grip ill. The

lower end of the lever 38 is extended below the pivots 48 into a finger grip 44. A spring 46 connects the lever 35 to an abutment on the bracket 42, and holds the lever 38 and iron '35 in the full line inoperative position shown in Fig. 1, with a face t on the rear sideof the iron in contact with the nozzle 20.

The ironing tool in this position is kept .hot

by heat radiated from the nozzle 20, and con ducted through the nozzle and the face .59. When it is desired to put the iron into use the operator pulls on the extension 44 with his forefinger, which moves the lever 38, link 24, and iron 38 into the dotted line positions .:in.Fig. 1, with the links 2 resting against the bosses 52 of the ears 21. This brings the ironing tool 30 directly in front of the nozzle where the hot air blast will maintain and perhaps increase its temperature, and will be diverted from the shoe. When the operator has finished using the ironing tool he will release the extension 44, and the spring GE will :snap the tool back into the inoperative full line position of Fig. 1. 7

in practice the operator will use the apparatus as described in the Bray application referred to, shrinking out the wrinkles in the upper by apply-- ing the hot air blast to the wrinkled portions. In case a wrinkle is encountered which is too pronounced to yield readily to the hot air blast alone, he will throw the ironing tool 36 into operative position and rub such a wrinkle down with it.

Having described our invention, what we claim as new and desire to secure by Letters Patent oi the United States is:v

1. An apparatus for use in operating on shoes comprising a tubular member adapted to conduct a stream of hot gas and to direct it upon a shoe, and an ironing tool mounted thereon and'having an inoperative position substantially in contact with the tubular member and an operative position remote from-the tubular member and directly in the path of the stream of hot gas, whereby the tool is heated by conduction through the tubular member when in inoperative position and is heated directly by the stream of hot gas when in operative position.

2. An apparatus for use in operating on shoes comprising a tubular member adapted to conduct a stream of hot gas and to direct it upon a shoe, an ironing tool mounted thereon and having an inoperative position substantially in contact with the tubular member and an operative position remote from the tubular member and directly in the path of the stream of hot gas, and a manually operable-member for moving the ironing tool from inoperative to operative position. 7

3. An apparatus for use in operating on shoes comprising atubular member adapted to conduct a stream of hot gas .and to direct it upon a shoe, an ironing tool mounted thereon and having an inoperative position substantially in contact with the tubular member and an operative position remote from the tubular member and directly the path of the stream of hot gas, and a manually operable member for moving the ironing tool from inoperative to operative position, said ironing tool being resiliently held in inoperative position.

4. An apparatus for use in operating on shoes comprising a tubular member adapted to conduct a stream of hot gas and to direct it upon a shoe, and an ironing tool mounted thereon and having an inoperative position substantially in contact with the tubular member and an operative position remote from the tubular member and directly .in the path of the stream of hot gas, whereby the tool is heated by radiation from the tubular member when in inoperative position and is heated directly by the stream of hot gas when in operative position and whereby the s'trea1n of hot gas is diverted from the shoe when the ircning tool is in operative position.

5. An apparatusfor use in operating on shoes comprising a tubular member adapted to con-' duct a stream of hot gas and to direct it upon a shoe, and an ironing tool pivotally mounted thereon and having an inoperative position remote from the part of the hot gas blast and isvzinga-ble on its pivotal mounting to an operative position directly in the :path of the hot gas blast, said pivotal mounting-providing an abutment constructed and arranged to take the pressure transmitted from a shoe through the ironing tool when the tool is in operative position and is applied to a shoe. w
