This invention relates to automatic timecontrolled circuit-breaking devices, and par ticularly to that type of such devices in which an electrical treating apparatus after a desired period of time, is automatically shut off to avoid over-treatment; and is a division of my copending application'Serial No. 229,- 141, filed October 27, 1927.

An object of the invention is to provide a device'of the type described which will not only interrupt the circuit after a desired period of time, but will allow of a uniform treatment with the apparatus under varying voltage conditions. in the power line.

Another object of the'invention is to provide means ancillary to the time-control switch whereby the operator may-adjust the time period to compensate for voltage variations in the-power line.

Other objects of the invention will in part be obvious and will in part appear hereinafter.

The invention accordingly comprises the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the claims.

For a fuller understanding of the nature and objects of the invention reference should be had to the following detailed description taken in connection with the accompanying drawings, in which:

Figure 1 is a diagrammatic view of the wiring diagram of the novel apparatus connected to a power line and to a treating mechanism;

Fig. 2 is a plan View of one type of automatic time-control cut-oft device to which is applied the ancillary dosage indicator described herein;

Fig. 3 is an enlarged detail view of the indicator per se; and

Fig. 1 is a diagrammatic view of the apparatus installed on a permanent-waving machine.

Referring to the wiring diagram shown in Fig. 1 of the drawings, the numeral 10 desnates the leads of the power line; 11 the leads taken off from 10, and 12 the timecontrol switch which interrupts one of the 1 leads 11 and has a switch mechanism 13' and a clock mechanism'l l; 15 designates a, voltmeter bridged across the leads adjacent the switch 12; 16 the fuses,and 17 an electrical treating apparatus, I

Although any desired type of time-control switch may be used without departing from the spirit of .the present invention, atype which'has been found to be particularly detimer,Type T, manufactured by the Liebel- Flarsheim Company, of Cincinnati, Ohio. The present invention is not particularly concerned with the'details of the automatic timecontrol switch, but, in general, it may be a switch 13, which, in the L-F timer, is a toggle-switch, which istripped by the clock mechanism and which when in its off'position acts to stop the clock mechanism.

In accordance with the principles of the' present invention, the voltmeter 15 shown in detail in Fig. 3 is bridged across the leads controlled by the switch and is provided with a dual scale 19. This scale bears the usual voltage readings 20, particularly those volt ages within a range of 300 or so on either side of the normal voltage of 110, and an auxiliary scale 21, registering the minutes treatment required for a given dosage at any particular voltage.

Although the apparatus provided by the present invention is adapted for use on any electrical treatment apparatus in which accuracy of dosage is desired, such as, for example, therapeutic machines, radiant heat and other types of lamps, Morse-wave generator, galvanic and sinusoidal apparatus and the like, it has been found to be particularly useful in connection with permanentwaving machines.

If desired, the scale may indicate only treatment times as shown in Fig. 2 at 19, the same having been calibrated as above, or other scales of the dual type may be ar- .60 sira'ble is that known as the L-F treatment .70 functions also as awmding mechanism, and

ranged for other types of treatment machines, but, in general, the principle is the same.

Furthermore, since the voltmeter canbe used separately from the time-control switch as an indicator of the proper time for any desired dosage, it is to be understood that such use is within the scopeof" the present invention. In explanation of the scale figures given in Fig. 3, it might, be here explained that the usual time oftreatment with a permanent-waving ,machine when using a voltage of 110 is aboutieight minutes. The particular scale shown, therefore, is adjusted on .this basis to'compensate for variations in voltage. For example, if the voltmeter shows 117 volts-when the circuit is cl0sed, the proper time for treatment is indicated as seven minutes instead of eight, and the operator takes this into consideration either in setting the time-control mechanism when the voltmeter is used in combination therewith, or in shutting off the heater at "times if the voltmeter only is used. If desired, the dial of the voltmeter may also have printed thereon further'instructions to the operator, as indicated at 29, such as Add two'minutes for fine'hair' and three minutes for extremely fine hair. The use of the voltmeter with the time scale eliminates guesswork, insures correct treatment under varying Voltage conditions, and, when used in combination with the time-controlled switch, automatically cuts ofl the electricity at'the end of the treatment, thus allowing the operator to utilize the intervening time in doing other work. Furthermore, the use of the present device has a psychological .4 value, in that it assures the customer not only that the treatment will be correct, but that it will becut off at the proper time, regardless of-the whereabouts of the operator.

Referring further to Fig. 4, there is here shown a diagrammatic view of the apparatus installed on a permanent waving machine of the type described in my Patent No. 1,678,249, issued July 24th, 1928, on my application, Serial No. 130,873, filed August 23, 1926. When applied to a machine of this type the lead 11 coming off from the switch 13 is replaced by two leads 11, which pass through independent switches 31 and fuses 16 and thence to the ring-connector 30, where they are attached to one'of the semicircular contact-ring sections 22 carrying the socket-members 23. The other lead 11, which is not interrupted, also passes to the ring-connector 30, where it is connected with the circular contact-ring 24, which carries the socket-members 25. Also, asis shown in my said copending application, the ringcontact members may be connected with pilot lamps 26, which indicate when circuit is established between either of the semi- 5 circular rings 22 and the ring 24, and the decourse, that this particular permanent-waving machine is mentioned by way of example and that'any other type of machine may be used.
