4 Claims. 1

My invention relates to hair curlers and it is one object of the invention to provide a hair curler of such construction that a lock of hair may be coiled about a mandrel, hair pins of the bobby pin type applied through the coil transversely` thereof, and the formed curl dislodged from the mandrel together with the pins in such a manner that the pins remain firmly in place through the curl effectively retaining the curl close to a persons head and also preventing the hair from `working loose and uncoiling.

Another object of the invention is to provide a hair curler wherein the mandrel is formed integral with a body having a portion enlarged to form a head which may be readily grasped in a persons hand and carries a clip for securing the outer end of a lock of hair to the mandrel as the hair is coiled about the mandrel, the head being also formed with slots or pockets into which are fitted hair pins to be forced through the hair during formation of a curl.

Another object of the invention is to provide the hair curler with improved means for ejecting the hair pins from the pockets and forcing them through the coiled hair prior to dislodgment of the formed curl from the mandrel by other means associated with the pin ejecting means and operated thereby in proper timed relation to ejection of the pins.

Another object of the invention is to provide a hair curler wherein the pin ejecting device is so constructed that a pair of pins may be simultaneously moved out of the body and through a coil of hair as the ejecting means is pressed forwardly and the rear end of the ejector then have engagement with shank of the curl dislodger which removes the formed curl from the mandrel, the ejector being returned to its normal position by a spring coiled about the shank of the curl dislodging device and bearing against a tube which forms a portion of the ejector and serves to retract the curl dislodger as the ejector moves rearwardly.

Another object of the invention is to provide a hair curler having a body and mandrel formed of longitudinally extending sections which are firmly secured in engagement with each other and so formed that the pin ejector, the curl dislodger and the hair securing clips may be readily applied thereto and the two sections of the body then secured in face to face engagement with each other.

Another and important object of the invention is to provide the hair curler with improved means for spreading the arms or prongs of hair 2 pins as the latter are thrust through a coil of hair and then allowing the arms of the pins to return to a hair gripping position before the applied pins and the formed curl are dislodged from the mandrel of the curler.

A further object of the invention resides in the provision of an improvement upon my former patent, No. 2,240,241, issued April 29, 1941.

Another object of the invention is to provide a hair curler which is simple and durable in construction, inexpensive to manufacture and one which will be very efficient and useful in operation.

As aforementioned, my invention involves improvements specically on my former patent for Hair Curlers, No. 2,240,241, dated April 29, 1941, to which reference may be made,.if necessary. The primary improvement would appear to be in the method and means of spreading the ends of the hair pins for application to the coiled hair on a mandrel, although other improvements and details of construction will appear from the fol-v lowing description. Y

This improved hair curler has a body consisting of companion sections I and 2 which are formed of plastic or other suitable material. The two sections extend longitudinally of the body in side by side relation to each other and have flat inner side faces which are grooved longitudinally to form a bore 3 extending axially of the body. A lug 4 at the front end of the section I ts snugly into a socket 5 formed in the section and hold the two sections inV centered relation to each other when the sections are cemented to each other. At its front end the bore 3 communicates with a slot 6 consisting of registering slots 6 formed in the two sections.

The body is circular in cross section and the sections are of such shape that they form the body with a shank 1, a head 8 tapered rearwardly and merging into the shank, and a mandrel 9 which projects forwardly from the head and is tapered somewhat towards its front end so that it may be readily withdrawn from a rcurl formed about the mandrel. Ribs I are formed along the shank in spaced parallel relation to each other so that the shank may be rmly gripped and at its rear end the shank is formed withk an enlargement constituting a flange or co1- lar II which prevents a persons hand from slipping rearwardly 01T the shank while holding the curler. Channels I2 extend longitudinally of the shank from the rear end thereof and at their front ends these channels communicate with grooves I3 which extend longitudinally through the head 8 at opposite sides thereof and terminate in shallow extensions or grooves I3' which extend along the mandrel. The grooves I3 constitute seats for hair pins P of the type known as bobby pins and in order that these pins may be thrust forwardly into the grooves the two sections are formed externally with recesses I4 located adjacent rear ends of the grooves. Pockets I having side extensions or grooves I6 lead from the inner face of the section 2 and externally this section is formed midway its side edges with a recess I'I which extends longitudinally of the said Ysection in alignment with the slot 6 with its front end communicating with this slot, as shown in Figure 4, and its rear portion I'I widened and deepened, as shown in Figures 2 and 4.

By so forming the body of the curler, it may be readily held in one hand with its mandrel projecting forwardly and after the free end of a lock of hair H has been connected with the mandrel the curler may be rotated by turning or rolling movement applied to the curler and the hair coiled about the mandrel to form a curl C. The extreme end of the lock of hair must be secured to the mandrel in order to cause the hair to be wrapped about the mandrel during turning of the curler and in order to do so there has been provided a hair-gripping or starting clip I8 which extends longitudinally of the mandrel and is formed with a longitudinally extending slot I9 which registers with the slot E of the mandrel. This clip is formed of sheet metal and curved transversely for close tting engagement with the mandrel. The blank from which the clip is formed has a portion bent transversely to form a shank 20 of channeled formation which is of such width that it nts into the recess I'I where it is pivotally mounted by a pin 2|. At its rear end, the shank is-widened to form a nger engaging member or button 22 which fits into the enlarged rear portion I'I of the recess II and bears against the outer end'of a spring 23 by means of which the clip is normallyheld in a gripping position against the mandrel. The extreme end portion of a lock of hair will thus be firmly gripped and held in engagement with the mandrel.

After the hair has been coiled about the mandrel to form a curl, it must be prevented from 4uncoiling when removed from the mandrel. This is accomplished by means of the hair pins P which are mounted in the grooves I3 and thrust forwardly along the reduced portions I3 of these grooves and through the coil of hair transversely thereof. The arms or prongs of the hair pins must be spread apart as the hair pins are thrust forwardly and in order to do so, there have been provided spreaders 24.

These spreaders are formed preferably of sheet metal and each is slidably fitted into a pocket I5 with its side portions engaged in the side grooves I6 of the pocket. Each spreader plate is crimped transversely midway its width to form a trans'- versely V-shaped rib or cam 25 and the outer end of the plate is formed with a transversely arcuate edge so that the spreader is gradually reduced in width towards opposite sides of the outer end of the cam or rib. Thus, during ejece tion of the pins from the grooves I3 their prongs will be spread apart as they move across the cams and are forced into the coil of hair, as shown in Figure 6, and when the pins engage the arcuate edges of the spreader plates a carri action will be created which will shift the plates in wardly of the pockets I5 and entirely free the' hair pins from the spreaders. Resiliency of the hair pins will then shift their prongs towards each other into a gripping position and the hai-r curl will be gripped between the prongs `of the pins, as shown in Figure 7. Coiled springs 26 which' are seated in the pockets yI 5 and have their outer end portions engaged in slots 2'I formed inr the spreader plates urge these spreaders outwardly into position for exerting spreading action upon the prongs of the pins, and across' outerA ends of the pockets extend strips 28 which are embedded in the two sections of the body.

In order to eject the hair pins from the grooves I3 and force them into the hair coiled about the mandrel, there has been provided an ejector 29. This ejector is formed from a strand of stiff wire which is bent to assume a U-shape and' has a bridge 30 at its outerrend from which extend arms 3 I. The arms are slidably received in the channels I2 and are of such length thaty fingers 32 formed by bent front ends of the arms are disposed in, rear endsof the grooves I3 when' j the projector is in the rearwardly disposed normal position, shown in Figure 5.

A knob 33 is mounted at the rear end of the projector so that said projector may be easily pressed forwardly and its fingers 32 caused to move the hair pins forwardly from the retracted position, shown in Figure 5, to the extended position of Figure 6 in which the pins pass through the hair coiled about the mandrel with the hair gripped between the prongs of the hair pins and held in a curl about the mandrel.

A spring 34 which yieldably holds the ejector in its retracted position is housed in the bore 3 with its front end bearing against the front end of the bore and its rear end bearing against the constricted front end 35 of a tube 36. This tube is slidably mounted in the bore and has its rear end embedded in the knob or button 33 so that when pressure is applied to the button the pin ejector and the tube move together longitudinally of the curler. The spring 34 surrounds the shank 31 of a curl dislodger 38 formed from a strand of stiff Wire.

The curl dislodger is provided at its front end with a triangular cross head 39 formed by bending the front end portion of the wire strand from which the dislodger is formed and the rear portion of the strand is bent back upon itself to form a thickened end portion or abutment 49 which is disposed within the tube 3B and normally occupies the forward end portion thereof, as shown in Figures 4 and 5. End portions of the cross head protrude from opposite sides of the slot 6 for engaging the curl and pushing the curl longitudinally of the mandrel and ofi the front end thereof, one end of the cross head being engaged in the slot I9 and clip IB. When the pin ejector is pushed forwardly to the position shown in Figure 6 and the pins forced through the curl, the knob engages the rear end of the dislodger and continued pressure forces the dislodger forwardly so that its cross head applied pressure to the curl and forces it off the mandrel, as shown in Figures 7 and 8.

It will thus be seen that when pressure is applied to the button the pin projector is rst moved forwardly to implant the pins in the curl and the pin projector and the curl dislodger then move together as a unit to dislodge the curl and maintain the pins in the formed curl during movement of said curl off the mandrel. After the curl has been dislodged from the mandrel, pressure upon the button is relieved and the spring 3a expands. As the spring expands its pressure against the constricted front end of the tube shifts the tube and the ejector rearwardly to retract the ejector and the constricted end of the tube then engages the abutment formed by the bent end portion 40 of the dislodge whereupon the dislodger will be carried rearwardly to its retracted position together with the pin ejector as the ejector continues rearward movement to a fully retracted position as shown in Figure 4.

From the foregoing description of the construction of my improved'hair curler, the method of operation and application thereof to use will be readily understood and it will be seen that I have provided a comparatively simple, inexpensive and efficient means for carrying out the various objects of the invention.

While I have particularly described the elements best adapted in perform the functions set forth, it is apparent that various changes in form, proportion and in the minor details of construction may be resorted to, without departing from 6 the. spirit or sacricing any or the principles .of the invention.
