Oct. 3, 1950 s, Q KAMARA v 2,524,058
ELECTROMECHANICAL HAIR CURLER Filed July 18, 1947 111 z'eutor Sori Bakr/ Kamara WWW Patented Oct. 3 1950 UNITED sums-PATENT OFFICE The present invention relates to hair curlers for-use in hairdressing establishments, in the home and elsewhere for hair waving and conditioning purposes and has more particular reference to an electro-mechanical-type characterized by a motor driven curling mandrel.
Needless to say, powered revoluble winding and curling mandrels in hair curler constructions are not new. As a matter of fact, many and varied efforts and attempts have been made by others in this line of endeavor to properly devise an unqualiedly acceptable electro-mechanivcal curler of the rotatable-type. Then too, and in addition, it is not novel to utilize, in thesetypes of curlers, heatingcores and elements. lIt folu lows, that since the broad and fundamental. arpects are old, factors of relative novelty pertain, primarily noticed, to a choice and selection of novel elements; their coordination and attending results. It follows that it is the purpose of the instant invention to structurally, functionally and otherwise improve upon known types of powered hair curlers, this through the instrumentality vof what is believed to be a more adequate and satisfactory structural organization, a particular adaptation thereof which is possessed of refinements and other accomplishments needed in the trade.
Other objects and advantages will become more readily apparent from the following description and the accompanying illustrative drawings.
In the drawings, wherein. like numerals are employed to designate like parts throughout the views:
Figure lis a View in sectionand elevation showing a complete hair curler of the motor op, erat'ed type constructed in accordance with the principles of the present invention;
Figure 2 is an enlarged cross section on the line 2-2 of Figure l, looking in the direction of the arrows:
Figures 3, 4 and 5 respectively, are enlarged cross sectional views on the planes of the lines 3 3, i-L and 5-5 of Figure 1, all looking the direction of the indicating arrows.
Briefly and broadly, the structure, in unitary or overall appearance, is of the so-called pistolgrip type and, in practice, includes an angular grip and trigger-like part forming the conn veniently accessible start-stop device.
The main body or casting, as a unit, is denoted by the numeral 5 and includes an open bottom cylinder 'l constituting a hand-grip as well as a holder for an appropriate electric motor 8. The current supply cord 9, leading to the motor is 5 claims. (o1. 132-34) provided witha suitable switch IU and oor plug, or the like (not shown) to supply the motor with current. The arbor or shaft I I has a conical driving terminal I2 in constant friction driving contact with a propelling disk I3. The disk has a marginal brake flange Ifi to accommodate a lateral brake shoe I5 formed on one end of a substantially Lshaped trip-lever I8. Theftrip-lever is provided with a return and retaining spring I1 of an appropriate type and the portion ES of the trip lever is pivotally mounted between lugs or ears l5, as shown at 2G (see Fig. 5 in particular). rEhe lateral lefthand end portion of the body is fashioned into a reduced cylindrical bearing 2| `having a collar-like bushing 22 receiving and Supporting a rotatable hollow curling mandrel 23. This mandrel is closed at its outer end and serves to house an appropriate electrical core or heating element 24, the same supported at one end as at 25. The opposite end of the core projects through and beyond the mandrel and into an insulator sleeve 26 where it receives current from a suitable connector 2I connected with the motor. The aforementioned friction disk is provided with a hub 28 fastened as at 29 on the mandrel. It will be noted in the upper right in Figure 1 that the intermediate or junctional portion between the hand-grip 'I and bearing 2l is provided with an accommodation slot permitting protrusion and proper mounting of the brake flange and friction disk. This arrangement also provides an ideal arrangement to support the trigger I6 `and to position the brake finger I5 in proper relation to the brake flange. What is more, at this point and interiorly the body is fashioned with an appropriate enlargement 3G which is socketed for anchorage of one end of the mandrel 23 and which accommodates the insulator 26 which, in turn, provides for convenient assembling and anchorage of the heating element.
The sheathelike hair clamping blade 3l includes a channel portion 32 which conforms to the mandrel. It also includes usual attaching ears 33 which are pivotally mounted at 34 on diametrically opposite sides of the mandrel. The lateral operating end portion terminates in a hook 35 which is connected with an operating ring 36 surrounding the bearing. A suitable spring 31 is employed and is interposed between the member 3i and the mandrel to normally close said member for hair clamping and curling accomplishments.
In operation, the electric motor provides the source of energy and, through the medium of the drive shaft imparts rotary motion to the friction energy transmission disk I3 with the consequence that the mandrel is rotated for winding and curling purposes. So long as the brake shoe or finger I5 is applied to the brake ange, the mandrel stands still. The speed and degree of rotation is therefore determined by proper, as well as carefully regulated manipulation of the brake shoe, this by way of the trigger I6. Thus, we have on the hand-grip conveniently actuable stop-go means for the revoluble mandrel. Since the hair is wound on the mandrel and the mandrel turns as the hair is turned by way 0f the blade 3l, it is desirable that the ratio of speed between the motor driven arbor and mandrel be relatively slow in order to avoid over-winding, or winding in a manner which is too rapid for safety.
As previously stated, motor operated mandrels and hair curlers are old and the method and use of same is well known to hairdressers in beauty parlors and the like. In the circumstances, it seems not necessary to dwell upon features, advantages, construction and mode of operation.
A careful consideration of the foregoing description in conjunction with the invention as illustrated in the drawings will enable the reader to obtain a clear understanding and impression of the alleged features of merit and novelty sufcient to clarify the construction of the invention as hereinafter claimed.
Minor changes in shape, size, materials and rearrangement of parts may be resorted to in actual practice so long as no departure is made from the invention as claimed.
