9 Claims.

invention relates to electrical hair' waving machines for use in the heating of the hair to be curled or waved and wound upon curling rods in 'accordance with common practice.

Machines of this kind are commonly provided with a relatively large number of curling heater devices flexibly suspended through the medium of their c'urrentconductin'g leads, over the head of the person whose hair is to be curled or waved,

the heater devices being adapted for selective clamping to the different portions of the persons hair to be operated on and the leads to the heaters being associated with devices whereby the leads will extend from the heaters to the supporting structure above, in a substantially straight line.

My invention as to one of its features relates to the manner of supporting the current leads whereby the leads from their points of connection with the heater devices to the support from which they depend may be caused to extend in the desired substantially taut, or straight line, condition, and be readily separately adjustable to cause the heater devices to extend at the heights desired, 5 without undue wear of the parts, and entanglement of one lead with another.

Another object is to provide a machine which will be free of exposed wire loops and such other parts commonly used as add objectionable weight to the head of the person whose hair is operated Another object is toprovide a machine where-` by the possibility of objectionable electric conl tacts producing uneven heating of the heater devices will be avoided.

Another object is to provide for the accurate adjustment, with ease, of the height to which the several heater devices extend with resultant closer and better waving than possible with machines as hitherto provided.

Another object is to provide a machine presenting the adaptability for adjustment cf the leads as above stated which will be of simple construction, and whereby danger of impairment of its parts resulting in the burning of the person whose hair is being operated on, will be reduced to the minimum; and other objects as will be manifest from the following description.

The particular illustrated embodiment of my invention comprises a supporting member shown as in the form of a hollow vertically disposed shell 9 which may be supported in any desirable way, as for example on a post I0 vertically adjustable in a hollow standard II which in practice would rest at a base portion thereon on the oor. The machine also comprises electrical heating devices, current-conducting leads extending from the heating devices into the shell and supporting the heating devices to extend below the shell, wherein they are connected with outlet sockets carried by the shell, and elevation-controlling devices connected with the current conducting leads between their ends and supported on the shell for vertical adjustment thereon. In the construction shown two well known types of electric heaters are lillustrated by way of example, one, the Croquignole type, exemplied at I2, and the other the spiral socket type exempliiied at I3. Two only of each of these two types of heater devices are shown, there being provide-d as many of each type as desired. The machine shown is adapted for energizing twenty heaters of each of the two types referred to. Y

As usual, they Croquignole type I2 is a. split-l clamp form comprising the two clamp portions I4 each of which contains a section of an electric heating element, two sections of heating elements for the two clamp portions I4, being shown hair would on curling rods, comprises a single heating element as represented at I5.

Each pair of heating element sections I5 is connected together in series and with current conducting leads represented at Il, the leads I'I for each pair of adjacent heaters I2 being connected in parallel with an electric push-plug I8 as shown particularly in Fig. 8.

The heater element I6 of each spiral heater I3 is connected with current conducting leads I9, the leads for each pair of adjacent heaters I3 being connected in parallel with an electric push-plug 2i) as shown more paiiticularly in Fig. 7.

The shell 9 comprises a hollow cylindrical member 2l secured to the post I0 through the medium of the housing 22 oi current-controlling mechanism hereinafter referred to, the member 2i having a series of vertical slots 23, shown as forty in number, disposed about its circumference. The member 2I is connected at its lower end with a circular plate 24 containing apertures 25 disposed in circular series around the margin thereof, there being twenty of these apertures each to receive the leads of a pair of electrically connected heater devices. The member 2i and plate 24 are connected together by means of a ring 2B at the outer edge of the plate 24 and angles 2l secured to the plate 24 by bolts 28, the lower edge of the member 2| extending into the annular space 29 between the rings 2S and angles 2l and secured thereto by bolts Sil.

The upper end of the member 2l carries a removable cover plate 3l shown as of dome shape and extending at its annular lower rim portion into the upper end of the member 2l and resting on angle lugs 33 secured to the member Ell as by bolts 84 which also secure to the member il! a nishing band 35 applied to the outer Side of the member 2l.

The current conducting leads from each heater device are independently connected between their ends with a series of elevation-controlling devices 35 carried by, and arranged around the circumference of, the member 2|, whereby the elevation at which each heater device extends may be easily controlled as desired, forty of these controlling devices being provided in the particular construction shown for cooperation with the forty heater devices.

Each controlling device 35 comprises a bar portion 3l which extends through one of the vertical slots 23 in the member ZI; and a head, or knob, 38 of current insulating material secured to the outer end of the bar E? as for example by molding it in anchored position on the head, the bar 3i containing an opening, or openings, 39 to receive a portion of the molded head-forming material. The head thus exposed at the outer side of the member 2I serves as a means by which the operator may vertically adjust the device 35. The device 35 also comprises a cross pin 45 in the inner end of the bar portion Si between which and a washer li on the bar 3l, a loop portion 42 of the twisted leads is confined; and a coiled spring 43 surrounding the barY portion 3'! and interposed between the washer 4I and the member 2l and frictionally holding the device 35 to the member ZI in all of its positions of vertical adjustment thereon.

Preferably the portions forming the loop are sheathed in split rubber protectors 44 and the leads above and below, and closely adjacent to, the bar are secured together by metal clips 52a which as shown, may be of strip form each having a tongue at one end for insertion through a slot in the other end of the clip, the tongue being drawable through the slot to produce the desired clamping eifect and bent back to hold the clip in clamping position.

The machine also comprises electric sockets mounted on the plate 24 for receiving the plugs I8 and 253.

Ten sockets 45 for receiving the plugs I8, respectively, o-f the Croquignole heater devices I2, and ten sockets 45 for receiving the plugs 20, respectively, of the spiral heater devices I3 are provided, the sockets 45 being arranged in one circuit and the sockets 45 in another with controlling means for directing current to either group of sockets as desired.

iX o1 each of both groups of sockets are shown secured to the plate 24 by yoke-shaped members il and 48, respectively, fastened to the plate 23 by screws 4S and the remaining four of each of both groups of sockets are shown secured to the plate 24 by Z-shaped members 55 and 5I, respeetively, fastened to the plate 25 by screws 52.

The plate 24 also carries sockets 53 and 54 for two electric signal lamps 55 and 56, respectively, of diiferent colors as for example green and red, respectively, secured to the plate 24 by screws 57, the sockets 53 and 54 being connected in series with the groups of sockets 45 and 46, respectively, to indicate to the operator which group of heater devices are being energized.

As customary in machines of this general character switch means hereinbefore referred to and represented at 58 and 59 and located in the housing 22 and having turn buttons 50 and 6I, respectively, are provided for selectively directing current through the different kinds of heater devices I2 and I3, with time control mechanism incorporated therewith, whereby the current may be caused to flow to the energized heater devices for any one of a number of selected periods of time.

Referring now to the electrical circuit diagram shown in Fig. 3, the main line wires are represented at 62 and 63 and connect with the terminals 64 and 65 of a volt meter 66 also mounted in the housing 22.

The sockets 45 are connected in parallel by means of wires 61-83, inclusive, the wires 67-14 constituting one side of the circuit and the Wires 15--83 constituting the other side of the circuit, one side of the parallel circuit being connected with the lead 62 at the wire 6l and the other side of this circuit connected with one terminal 84 of the switch 58 by a wire 85 connected with the wire 15.

The sockets 45 are connected in parallel by means of wires 85-I2, inclusive, the wires 85-94 constituting one side of the circuit and the wires 95-I02 constituting the other side of this circuit, one side of this circuit being connected with the lead 62 by a wire ID3 connected with the wire IUI and the other side of this circuit being connected with the terminal |04 of the switch device 59 by a wire |05 connected with the wire 81.

The other terminals IIlB and IIl'I of the switch devices 58 and 59, respectively, are connected together by a wire |08 which connects with the lead 53.

From the foregoing it will be understood that the closing of the switch 58 will cause current to be supplied to all of the sockets 45 for the Croquignole heater devices; and that when the switch 59 is closed it will supply current to all of the sockets 46 for the spiral heater devices.

The sockets 53 and 54 are interposed in series in a wire |09 which connects with the wire 15,

and with the wire 94, a shunt circuit around the socket 54 being provided by a wire Ill) which connects with the wire 95 and with the wire |09 between the sockets 53 and 54. As will be understood, when current is being supplied to the 10 sockets 45 (the switch 58 being closed and the switch 59 open) current will also pass through the socket 53, the current passing over the wires 85, '|5, and |09 (through the socket 53 and to the wire I I0), and thence through wires 95|0| inclusive, to wire |05. When the switch 58 is open and the switch 59 closed, current will pass through the socket 54 which, by reason of the provision of the wire ||0, is in eiiect in parallel with the sockets 46.

In the use of the machine the several elevation-controlling devices would be adjusted vertically on the member 2|, independently of each other, to cause the heater devices to extend at the exact elevations desired, depending on the particular condition presented by the person whose hair is to be waved, it being understood that it is desirable that the heater devices be adjusted to such an elevation as to preclude objectionable slack and still avoid any undue pulling stresses on the hair; the waving of the hair by the machine being elTected by the heater devices in accordance with common practice.

The constructionshown not only greatly minimizes wear on the leads and resistance to adjustment of the heater devices in a vertical direction and minimizes danger of interference between looped leads within the shell, but affords means whereby the most delicate and accurate adjustments of the heater devices may be effected 40to the end not -only of adapting the machine for the performance of its work in a highly satisfactory manner, but minimizes inconvenience and danger to the person whose hair is being operated on.

45 Furthermore, the machine by reason of the provision of the shell as shown and described provides means for the ready upward escape of the heat from the heater devices, thus minimizing discomfort to the person whose hair is being 50 operated on, the shell, in effect, forming a flue which tends to draw the heat upwardly therethrough.

The signal lamps referred to not onl3r serve to indicate to the operator which set of heater de- 5 vices are being energized, but also serve in their use in connection with an open-work shell to afford an attractive Inode of illumination of the interior of the shell.

While I have illustrated and described a par- 60 ticular construction constituting my invention, I do not wish to be understood as intending to limit it thereto as the same may be variously modified and altered without departing from the spirit of 65 my invention, it being my intention to claim my invention as fully and completely as the prior state of the art will permit.
