419,825. Hair - waving apparatus. ETHELBURGA SYNDICATE, Ltd., 149, Leadenhall Street, London.-(Schulz, W.; 5A, Jungfernstieg, Lichterfelde, Berlin.) May 17, 1933, No. 14329. [A Specification was laid open to inspection under Sect. 91 of the Acts, Feb. 28, 1934.] [Class 131.] In hair-waving apparatus of the kind in which a heating element is arranged either to have a tress of hair wound around it or is arranged to surround a tress of hair which is wound on a curler, the element is heated by the combustion of a fuel air mixture which is passed over a known combustion catalyst, e.g. platenized asbestos, housed in the element. The fuel employed may be a gas, such as hydrogen, methane or acetylene, or a vapour, such as alcohol or petrol vapour, and the catalyst may be in the form of pellets strung on a wire. The heating elements may comprise a hollow curler or a U-shaped or hinged clip provided with a chamber or chambers for the catalyst and with an inlet and outlet for the fuel air mixture and the products of combustion respectively. Each heating element, e.g. the curler 11, Fig. 6, may be provided with a separate generator for fuel mixture comprising a perforated cup 25 containing absorbent soaked in volatile fuel through which air is drawn by a suction device 28 connected to the outlet of the element, or a series of elements may be connected by pipes 9, Fig. 1, to a single generator 1 containing a reservoir 4 for liquid fuel through which air is forced by a pipe 6. The generator 1 may be provided with a compartment 3 containing material, e.g. activated charcoal, for absorbing the products of combustion, the compartment being provided with nipples 8 connected by pipes 10 to the outlets of the heating elements. In a modification, the generator is mounted on a stand 30, Fig. 8, the fuel reservoir 4 being secured to the bottom of a gas-tight casing 32 carried by a hollow frame 33 on which is mounted the exhaust chamber 3. Air is forced through a diffuser 31 in the fuel by a fan 7, the mixture passing through conduits 37 to the pipes 9. The curlers 35 are provided at the ends with conical seatings engaged by nipples on the end of metal pipes 45, 46 on the ends of the pipes 9, 10. In a further modification, the mixture is obtained by injector action, gas under pressure being supplied through a a nozzle situated adjacent air inlets at the inlet ends of the curler, the curlers being connected to a casing supplied with gas from a generator mounted on the base of the stand.
