Abstract
Abstract In an ironing press a common knob controls simultaneously the adjustment of a thermostat in accordance with the temperature to be reached by the ironing plate according to the material to be ironed and the progression of a tape which is thus caused to move between a source of light and a panel provided with a translucent strip and with symbols corresponding to the temperature required for these different materials. A line separating two successive transparent and opaque sections of the tape is thus automatically brought into registry with the symbol corresponding to the temperature for which the thermostat is adjusted at the same time.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
132 words
In an electric ironing press provided with a heating plate, a supply of electric energy feeding said plate and an adjustable thermostat controlling the temperature produced by said supply in said plate, the combination on a carrier arm, of a tape provided with a reference mark, a source of light, and a panel in front of said source of light carrying a plurality of temperatureindicating marks, a hand-operable control knob, and means through which said knob is adapted to control simultaneously the adjustment of the thermostat in accordance with the desired temperature to be assumed by the plate and the progression of the tape through the gap between the source of light and the panel to make the reference mark on the tape register with a selected temperature-indicating mark on the panel.
Claim 2
Dependent Claim
132 words
In an electric ironing press provided with a heating plate, a supply of electric energy feeding said plate and an adjustable thermostat controlling the temperature produced by said supply in said plate, the combination on a carrier arm, of a tape provided with a reference mark, a source of light, and a panel in front of said source of light carrying a plurality of temperatureindicating marks, a hand-operable control knob, and means through which said knob is adapted to control simultaneously the adjustment of the thermostat in accordance with the desired temperature to be assumed by the plate and the progression of the tape through the gap between the source of light and the panel to make the reference mark on the tape register with a selected temperature-indicating mark on the panel.
Claim 3
Dependent Claim
47 words
An arrangement as claimed in claim 1, wherein the panel is opaque and is provided with a light-permeable strip extending over the tape in a direction parallel with the direction of progression of the latter in the gap, the temperature-indicating marks on the panel being also light-permeable.
Claim 4
Dependent Claim
35 words
An arrangement as claimed in claim 1, wherein the tape includes two successive differentiated sections of which one at least is light-permeable, the line separating said two sections forming the reference mark on the tape.
Claim 5
Dependent Claim
54 words
An arrangement as claimed in claim 1, wherein the knob-controlled means include a rotary drum over which one terminal section of the tape is wound, a return spring fitted between a stationary point and the other terminal section of the tape, and rollers over which the tape is urged into and through the gap.
Claim 6
Dependent Claim
80 words
An arrangement as claimed in claim 1, wherein the knob controlled means include a rotary drum, a return spring one end of which is secured to a stationary point, a securing member fitted between one end of the tape and the free end of the spring, the other end of the tape being secured to the drum to ensure the winding of the tape round the latter, and rollers over which the tape is urged into and through the gap.
Claim 7
Dependent Claim
81 words
An arrangement as claimed in claim 1, wherein the knob-controlled means include a rotary drum, a return spring one end of which is secured to a stationary point and the other end of which is secured to one end of the tape, a securing member rigid with the drum and engaged by the other end of the tape to ensure the winding of the tape round the latter and rollers over which the tape is urged into and through the gap.
Claim 8
Dependent Claim
129 words
An arrangement as claimed in claim 1, wherein the knob-controlled means include a rotary drum, a return spring one end of which is secured to a stationary point, means securing the ends of the tape respectively to one of the following parts; the free end of the spring and a point of the drum, at least one of last mentioned means being constituted by a socket rigid with the corresponding part and provided with a slot along a generating line, a spool revolvably carried inside said socket and provided with a slot along a generating line, the corresponding tape end being introduced into the slots upon registry between them to ensure the winding of the tape round the spool until its convolutions engage the inner periphery of the socket.
Claim 9
Dependent Claim
87 words
An arrangement as claimed in claim 1, wherein the knob-controlled means include a rotary drum over which one terminal section of the tape is wound, a return spring fitted between a stationary point and the other terminal section of the tape, rollers over which the tape is urged into and through the gap, a shaft coaxially driven by the drum, a shaft controlling the thermostat and a pivotal connection between said shafts to allow the thermostat to assume a pivotal movement with reference to the carrier arm.
Claim 10
Dependent Claim
131 words
An arrangement as claimed in claim 1, wherein the knob-controlled means include a rotary drum over which one terminal section of the tape is wound, a return sprinG fitted between a stationary point and the other terminal section of the tape, and rollers over which the tape is urged into and through the gap, a shaft coaxially driven by the drum, a shaft controlling the thermostat and a pivotal connection between said shafts to allow the thermostat to assume a pivotal movement with reference to the carrier arm, said pivotal connection including two sockets respectively rigid with the cooperating ends of said shafts and the inner cross-section of which is non-circular and a rod the ends of which form heads engaging the corresponding sockets to revolve in unison with the latter.
