Application March 29, 1944, Serial No. 528,583

13 Claims.

The present invention relates to new and useful improvements in hair curlers of a type embodying a winding mandrel which has been preheated and on which the hair is wound together with an insulated container in which the mandrel, with the hair wound thereon is placed, to protect the scalp of a person from the heat of the mandrel while the enclosed mandrel is supported in a position for a predetermined period 'while the hair is being curled. An important object of the present invention is to provide means for rotating the mandrel in order to wind the hair thereon without necessitating the heated mandrel coming into contact with the fingers f the operator.

It is a further object of the invention to provide means carried by the rotating mechanism for opening and closing the clamping member of the mandrel which serves to clamp the hair thereon.

A further object of the invention is to provide a hair curling apparatus of this character by means of which the aforesaid object may be carried out in a simple and practical manner and which at the same time is efficient and reliable in performance and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming art hereof wherein like numerals refer to like parts throughout, and in which Figure 1 is a side elevational view of the spinner or rotating mechanism for the mandrel and with the mandrel shown in position thereon,

Figure 12 is a sectional view taken substantially on a line l2--l 2 of Figure 11, and

Figure 13 is a side elevational view of the heater for the mandrel and with parts broken away and shown in section.

Referring now to the drawings in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral 5 designates a spinner generally and which includes a casing 6 of tubular form with an opening 1 at one end and having a tube 8 rotatably supported therein on a bearing 9 which forms a seat for the bottom of the tube and which maintains the tube within the upper portion of the casing.

To the front end of the tube 8 is secured a longitudinally extending bracket 10 having a transverse extension I let its front end provided with an opening I2 and on one edge of the opening 12 is formed a stationary jaw 13 which projects outwardly through the opening I.

A spring jaw M has one end attached to the tube 8, adjacent its front end, the jaw l4 extending forwardly through the openings 1 and I2 and the jaws I3 and I4 have notches I5 and H5 in their opposed faces adapted for engaging a flange II formed on one end of a tubular mandrel Hi.

The mandrel l8 includes a clamping member l9 extending longitudinally of the mandrel, the clamping member being pivotally mounted adjacent one end on a pin 20 carried by the mandrel and on which a coil spring 2| is also carried for urging the clamping member into a closed position against the mandrel.

The flange I1 is interrupted to receive a flange segment 22 adjacent the pivoted end of the clamping member IS, the segment 22 forming a continuation of the flange [1.

The outer end of the jaw I 4 is bifurcated to form spaced

parallel arms

23 and 24 at its outer end as shown to advantage in Figure 5 of the drawings, between which a pin 25 extends for pivotally supporting a jaw segment 26 between the

arms

23 and 24, the segment 26 likewise having a notch 21 for engagement with the flange segment 22 of the clamping member I9.

The pivoted jaw segment 26 is movable independently of the jaw I4 by means of a manually operable plunger 28 slidably carried in the casing 6 and having its inner end adapted for engaging the rear end of the jaw segment 26 whereby a downward pressure on the plunger, as indicated by the arrow in Figure 6 of the drawings, will cause a radially inward movement of the flange segment 22 of the mandrel and thus open the clamping member IS. A coil spring 29 held by the extension In urges the jaw segment 26 into an opposite direction.

The jaw member l4 together with the pivoted jaw segment 26 is released from the mandrel by means of a spring lever 30 which is attached at one end to the top of the casing 6 and is formed with an inwardly extending plunger 3| working through an opening 32 in the casing for engaging the jaw |4 adjacent its rear end. A downward movement of the lever 3|] will move the jaw 4 downwardly to release the mandrel.

The tube 8 is formed with teeth 33 at its rear end operatively engaged with a gear 34 freely rotatable on a pin 35 supported in the casing 6, the gear having a pinion 36 attached thereto for engagement with a rack-bar 31 which is slidably mounted on a bar 38 supported in the opposite end of the casing 6. A coil spring 39 mounted on the bar 38 behind the rack-bar 31 urges the rackbar into a forward position.

The bottom of the casing 6 is formed with a longitudinal slot 40 adjacent its front end and through which a finger grip 4| projects for attaching to the bar 31. One edge of the slot 40 is formed with teeth 40' adapted for engagement by one edge of a pivoted locking member 42 carried by the finger grip 4| to secure the rack-bar in any desired position of its travel. The pinion 35 is disposed in the path of travel of the rackbar so that upon a rearward sliding movement of the rack-bar the pinion 36 and gear 34 will be rotated, thus causing a rotation of the tube 8 and I a similar rotation of the mandrel |8 carried at the front end of the tube by means of the jaws l3 and 4.

The ratio of the pinion 36 with the gear 34 is preferably arranged so that -a single rearward sliding movement of the rack-bar 31 will be sufficient to rotate the mandrel i8 to produce a complete winding movement of the hair 43 thereon.

The mandrels 8 are first preheated in an electrio or other heating container 44 having a hinged A lid 45 to provide access thereto, with the flanges ll of the mandrel positioned uppermost so that the same may be gripped by the jaws l3 and I4 and removed from the heater without the mandrel coming into contact with the fingers of the operator. After one of the mandrels has been removed from the heater the pivoted jaw segment 26 is actuated by the plunger 28 to open the clamping member Is to permit the hair to be clamped to the mandrel, after which the fingergrip 4| is moved rearwardly of the casing which causes a rotation of the tube 8 through the rackbar 31, pinion 36, gear 34 and the teeth 33 on the tube and since the jaw members 13 -and 14 are carried by the tube 8 the mandrel will be rotated so as to wind the hair thereon.

After the winding of the hair on the mandrel has been completed the mandrel is then placed Within a container 46 having a slotted opening 41 to accommodatethe hair adjacent the scalp, the end of the container beingclosed by a hinged door 48 and secured in a closed position by a catch 49. The container 46 is enclosed within a felt or other cover 50 to act as an insulator to protect the scalp from the heat of the mandrel.

An eye 5| iscarriedby the container 46 to which a spring suspension device '52 is attached and by means of which the mandrel and container may be supported out of direct contact with the scalp, the member 52 being supported a spinner including a from a suitable overhead structure (not shown).

One side of the casing 6 is provided with a finger-grip 53, preferably engageable by the middle finger of the operator to assist in holding the casing during the manipulation of the finger-grip 4| for rotating the spinner during the winding of the hair on the mandrel.

It is believed the details of construction, manner of operation and advantages of the device will be readily understood from the foregoing without further detailed explanation.
