In describing the invention, I shall refer to the drawings in which'simila'r reference characters designate corresponding parts throughoutthe several views and figures. This improved hair curler has a mandrel 1 consisting of a metal rod of any desired length and'diameter and at its inner end the mandrel carries a look by means of which 7 it isto be removably fixed to a lock of 1hair'2 which is to be wound about'the mandrel and form' a tight coil 3' held in a firmly wound condition about the I mandrel while it is subjected to heat during a curling operation. The lock has upper and lower 80 through' the mandrel andwinder along the line 12--12 of Figure 10;

walls 4 and 5 which together with a marginal wall or collar 6 define a housing and referring to Figure 4, it will be seen that the upper wall is formed integral with the mandrel and spaced from the inner end thereof whereas the lower wall 5 consists of a separate disk fitted upon the reduced inner end 7 of the mandrel. This reduced inner end of the mandrel is upset after the disk or wall 5 has been applied and serves as a rivet to firmly hold the lower wall in place. The marginal wall or collar 6 is applied before the wall 5 is set in place and has an inwardly extending annular flange 8 which fits between marginal portions of the upper and lower walls. A portion of the flange 8 is extended inwardly to form an annular lip 9 terminating in tongues 10 and 11 at its end and by referring to Figure 6, it will be seen that the portion of the flange 8 above the lip 9 gradually reduces in width toward the tooth or tongue 10 to form a cam surface 12. Opposed recesses 13 and 14 which open through their margins are formed in the walls 4 and 5 so that hairmay be engaged through the locks and ends of the collar 6 terminate in such spaced relation to each other that when the collar is in the position shown in Figure 2, the open ends of the recesses will be exposed. When, however, the collar is turned aboutmargins of the upper and lower walls to the position shown in Figure 3, a portion of the collar will extend across the open outer ends of the recesses and serve as a closure for the same. In View of the fact that the wall 4 is formed with an upstanding marginal flange 15, the circumferentially extending edge face of this wall will be comparatively deep and provide a good bearing surface which will prevent excessive wear and also guide movement of the collar and permit it to be easily turned.

screw 17 passed through an opening 18 formed centrally of the shield and screwed into a threaded socket 19 formed in the lower end portion of the mandrel axially thereof. This shield will,

therefore, be firmly held in place by a removable fastener having its head countersunk within the central portion of the shield and by referring to Figure 7 it will be seen that the shield has a portion cut therefrom to form a recess 20 which registers with and corresponds in dimensions to the recesses 13 and 14.

When this mandrel is in use, a lock of hair after being passed through the registering recesses 13, 14 and 2G, is to be very firmly gripped in order to securely lock the mandrel to the lock of hairy In order to do so, there has been provided a hair gripper or arm 21 which is curved longitudinally in order to extend circumferentially of, the housing across the registering recesses when in the closed position shown in Figure 3. This hair gripper or arm has one end portion thickened to form a heel 22 of such thickness that it will fit snugly between the upper and lower wall of the housing and through this heel is formed an opening 23 to receive a screw 24-engaged through aligned openings 25 and 26 formed in the upper and lower walls and serving as a pivot pin about which the gripper swings from the opened position shown in Figure 2 to the closed position shown in Figure 3. At one end the heel is formed with a shoulder 27 for engagement by the tongue 10 and at its other end, the heel is formed with a shoulder 28 for engagement by the'tongue 11. Referring to Figures 2 and 3, it will be readily seen that when the collar 6 is turned from the position shown in Figure 3 towards the position shown in Figure 2 and the end of t e collar carrying the tonguelO moves across the recesses, the tongue 10 by contacting with the shoulder 2'7 will serve to swing the gripper or arm 21 about its pivot to the opened position and retain it in this open position. A lock of hair may then be moved into place withinthe registering recesses of the housing and pad or shield after which the collar may be rotated in a reverse direction. As the collar moves in this direction, the cam surface 12 will act against the arcuate edge of the gripper to swing the gripper inwardly towards a closed position and the lock of hair will be forced towards inner ends of the recesses and very firmly gripped. The collar moves across outer ends of the recesses to close the same and firmly holdthe gripper in a hair gripping position. In casera very small lock of hair is engaged through the recesses of the lock or the device is not in use, the collar may be fully turned to the position shown in Figure 3 in which position, the tongue 11 will engage the shoulder 28 and prevent further rotation of the lock in this direction. Therefore, rotation of the collar about the housing will be controlled and the gripper will be positively moved to an opened or closed position. V

The winder illustrated in Figures 8 through 18 and by means or which the lock of hair is to be wound about the mandrel to form thecoil 3 is formed of strong metal and has a tubular shank 29 having a skirt 30- carried by and, projected from its inner end. The outer end portion of the shank is split as shown at 31 to permit the shank to frictionally grip the mandrel and yieldably re-.

sist movement of the winder upon the 'mandrel when, the device is in use. There has also been provided turning arms 32 projecting radially from they shank intermediate its length in order that the shank may be grasped and easily rotated about the mandrel.

Referring particularly to Figures 13 and 15, it will be seen that the skirt is in the form of a cup constituting an entrance the winder as shown in Figure 11 andhaving an extension 34 leading from one end of the entrance through the head of the skirt or cup circumferentially thereof. At one side of the entrance 33, there has been formed. a fiat surface 35 for directing a lock of hair inwardly into the winder and at the other side of this entrance,

there has been formed a hinge ear 36 to which are pivotally connected hinge ears 3'7 formed upon a closure 381 This closure is arcuate when viewed from either end as clearly shown in Figures 11, 14 and 16 and is extended beyond the hinge ears 3'7 to form a tongue or inner end portion which is snugly received in a seat 40 within the walls when the closure is in theclosed position shown in Figure 12.

Referring to Figure 14, it will be seen that when the closure is shut, it is spaced slightly from lot - the mar inal edge of the fiat sur ace '3 in o d to perm t h s that s a e o guises e k o h ir nw h we n its free edg and the e ehd the l s eh etere helhtl; et-rha m move inwa when he l in e is t a l applie an ate s own in Figure 1 and a t moves n a thx h 'e hsh e q hutte w l be w n outwa d y t w ds an open nh itiqn- Ma ginal e ges of e el bou the o en f d o e ki a bev l ed a hown at hetm th skirt to fit ti htl about th lock o hai a i r undabout he mandr l b urnin u the win e ehdtor e t is ha t h y a ns the,

This will confine the lock of hair and prevent it from slipping outwardly through the entrance as the winder is rotated aboutthe man- In view of the fact that the shank of the winder has gripping engagement with the mandrel, it will be frictionally bound to the sameand although it may be turned about the mandrel and may be slid longitudinally thereon, it will remain in a set'position and serve as a binderto retain the lock of hair tightly wound about the mandrel and prevent it from slipping and uncoiling until the winder is manually removed after a curling operation is completed. The winder illustrated in Figures 17 and 18 is similar in construction to the form previously described and correspondingelements are indicated by the same reference nu merals. In this embodiment of the invention, the

closure 44 has its inner end portion forming a tongue corresponding tothe tongue 39 of the closure 38 but the outer portion of this closure has its upper and lower edges extending parallel The upper and both out along straight lines. edge of the closure extends in the plane of the upper edge of the inner tongue or end portion and the upper portion of the fiat face 35 projects above the closure as clearly shown in Figure 17 and takes the place of the extension 42. The walls of the skirt are of an even thickness throughout their depth instead of being formed with a flared mouth. The operation of this form of winder is the same'as already described and referring to Figure 18, it will be seen that the lock of hair may enter the skirt or cup of the winder and after moving the closure to an opened position during entry, will engage the tongue or inner end por- 7 tion of the closure and swing the closure to a closed position as the lock of hairis wound about the mandrel.

From the foregoing description of the construction of my improved curler, the operation ereo a he met -9f appl i th same t9 use w lrb r adi .hh e ft et w be seeh that I have provided a simple, inexpensive and t e t mean fo car tu the Ob e o h invention and while I have particularly described the elements best adapted to perform the functions set forth, it is obvious that various changes in form,.proportion and in the minor details of construction may be resorted to.
