Jam. 23, 1945. 1.. EISENMAN HAIR CURLER Filed May 29, 1943 WV WY Q MN Patented Jan. 23, 1945 UNITED STATES ""PATENT OFFICE 2,367,854 HAIR CURLER Louis Eisenman, Brooklyn, N. Y. Application May 29, 1943, Serial No. 489,050

14 Claims.

This invention is an improvement over that disclosed in my prior Patent No. 2,328,331, dated August 31, 1943, Hair curler, and relates primarily to hair curlers of that type comprising a rotatable mandrel upon which a lock of hair may be easily and quickly wound and then slipped off the mandrel endwise in a curled condition between the two legs of a bobby pin held by the curler.

One of the objects of the present invention is to provide a hair curler of the above general character which may be easily and conveniently manipulated and which will be reliable and emcient in action and operation.

A further object is to provide a practical hair curler of the above general character which will automatically openthe two leg of a bobby :pin as the curl is slipped from the mandrel.

A further object will be to provide a hair curler of the above general character having relatively 1 few parts which may be inexpensively manufactured and assembled.

Other objects will be in part obvious from the annexed drawings and in part hereinafter indicated in connection therewith by the following analysis of the invention.

This invention accordingly consists in the features of construction, combination of parts, and in the unique relation of the members and in the relative proportioning and disposition thereof, all as more completely outlined herein.

To enable others skilled in the art fully to comprehend the underlying features of this invention, that they may embod the same by the numerous modifications in structure and relation contemplated by the invention, a drawing depicting a preferred embodiment of the invention forms a part of this disclosure, and in such drawing like characters of reference denote corresponding parts throughout the several views, in which Figure 1 is a longitudinal elevational view showing the hair curler in normal position, certain parts being dotted in order to more clearly illustrate the relation;

Figure 2 is a similar view of the same mechanism with the parts in the position where a curl is about to be slipped off the mandrel;

Figure 3 is a detail plan view of one end of the device as shown in Figure 1;

Figure 4 is a detail vertical sectional view taken on the line 4-4 of Figure 3; and.

Figure 5 is a transverse sectional view on the line 55 of Figure 3.

Fig. 6 is a detailed longitudinal section of one end of the device.

Fig. 7 is a transverse section taken on the line l---'! of Fig. 6.

Referring now to the drawing in detail and more particularly to Figure 1', [0 indicates a mandrel of conventional form provided with a clip 9 l which is pivoted at l2 and is adapted to be raised from the mandrel ID by a downward movement upon the thumb piece l3 thereby to permit a lock of hair to be slipped between'the mandrel and the clip in the usual well-known mannerprior to rotating themandrel.

The mandrel It is adapted to be rotated freely upon a spindle 14 by means of a knurled'finger piece I 5 thereby to wind the hair uponthe man,- drel. At the extreme right of Figure 1 there is shown a clamping member IB which may have a comb ll, if so desired. The comb is convenient inorder to comb out a. lock of hair from the head and then reverse the curler therebyto slip the end the lock of hair between the mandrel and clip Intermediate the operating member I 5 and the part I 5 is a fixed stop member [8 pinned to the spindle which limits the movement of the part l5 towards the right and between'the parts it and I8 is an elongated member 20 which is also rotatably mounted upon the spindle at its right hand end and terminates at its opposite end in a downwardly bent spoon-like portion 2| having a. groove 22 in its lower part, the under part of which coacts with a groove 23 in the enlarged portion 24 of the extreme end of the spindle id (Fig. 5). This part 24 is provided with a longitudinal and substantially central hole or opening 25 adapted to receive one of the legs 26 of the bobby pin, the other leg 21 being adapted to rest in the recess 22 in the bottom of the spoon iii. The recess 23 which coacts with the groove 22 in the top or upper portion of the enlarged end 2! thus prevents relative movement of the arm under normal conditions. With the upper part of the bobby pin 21 resting in the top of this groove 22, as shown clearly in Figure 2, then the entire construction has a relatively rigid condition when in operation.-'

The mandrel I0 is hollow on its interior and a collar 3| is rigidly secured in any desired manner to the spindle I 4 and acts as an abutment for a spiral spring 32 within the mandrel, the opposite end of which spring coacts' with the end wall ofthe actuating member I 5. Thus after the curl is formed and the mandrel is moved relatively towardsthe left as shown in Figure 2, this spring is compressed and, on release of the actuating member, this spring returns the parts from the position shown in Figure 2 to the normal position shown in Figure 1.

However, it will be noted particularly -that the end of the mandrel I is provided with a conical or spherical portion 34 which is adapted to coact with the downwardly inclined part 35 of the member 20 shown in Figure 1. Thus, as the mandrel is moved towards the left, this conical portion 14 tends to wedge under part 35 and raise the same upwardly to the position shown in Figure 2 thereby raising the spoon 2I at the end of the member 20 which in turn carries the upper leg 21 of the bobby pin to provide a space into which the curl 36 is slipped. As soon as this operation is completed then the mandrel is released to move towards the right and the bobby pin clamps onto the curl and this pin, with the curl, may be bodily removed from the device and a new bobby pin inserted as shown in Figure 1', whereupon another curl may be formed and secured.

From the above it will be seen that the present invention provides a simple and practical hair curling device having relatively few parts which may be inexpensively manufactured and assembled. The device is particularly convenient in its ease of operation whereby a curl may be easily and quickly formed upon the mandrel and equally easily and quickly slid off to one side with the curl almost automatically held between the two parts of th hobby pin.

Without further analysis the foregoing will so fully reveal the gist of this invention that others can, by applying current knowledge, readily adapt it for various applications without omitting certain' features that, from the standpoint of the prior art, fairly constitute essential characteristics of the generic or specific aspects of the invention, and therefore such adaptations should and are intended to be comprehended within the meaning and range of equivalency of the following claims,
