In describing the invention, I shall refer to the drawings in which similar reference characters designate corresponding parts throughout the several views.

The curler illustrated in Figures 1 through '7 has a mandrel I formed of metal. This mandrel may be of any length and diameter desired and for the major portion of its length is circular in cross section and of the same diameter. Its upper end is reduced to form a finger hold 3 which is also circular in cross section and its lower end is reduced to form a neck 6 which is rectangular in cross section and formed with a threaded socket 5 to receive a screw 5 as shown in Figure 6.

The hair engaging lock which is associated with the spindle is also formed of metal and consists of a disc 7 which turns relative to the mandrel and upper and lower discs 8 and 9 firmly carried by the neck 1 and formed with rectangular openings Ill and H to receive the neck.

Referring to Figure 6, it will be seen that when the discs 8 and 8 are applied to the neck and the screw 6 screwed into the socket 5 with its head bearing against the under face of the disc 9, the two discs will be prevented from moving off of the neck and since the disc 8 is formed with a hub l2 against which the disc 9 bears, the two discs will be retained in spaced relation to each other and the disc l which is disposed between the discs 8 and 9 and formed with an enlarged opening l3 to receive the hub of the disc 8 will be permitted to turn freely between the discs 8 and 9 relative to these discs when the disc 1 is grasped by its flange l4 andmotion imparted to rotate this disk relative to the mandrel and discs 8 and 9. A flange I5 is formed about margins of the disc 8 to bear against the flange M as shown in Figure 6 and referring to this figure, it will be seen that the flange l4 not only extends upwardly above the disc I but also projects downwardly to encircle the disc 9. Therefore, the disc I will be prevented from tilting transversely upon the hub l2 and will be permitted to rotate freely relative to the discs 8 and 9. The opening l3 formed in the disc I is extended to form a throat I 6 opening through the marginal flange 94 of this disc and this throat is intended to register with slots H and i8 formed in the discs 8 and 9. It will be noted that the slots ll and 58 are so cut that their inner ends are extended at one side as shown at l9 and 25, thereby causing these discs to be formed with fingers 2| and 22 which are intended to extend across a lock of hair and force the hair into the inner end portion of the side extension N5 of the slot l5. This side extension is gradually reduced in width towards its inner end and therefore the hair will be firmly wedged into this portion of the slot it when the curler is in use. Referring to Figures 4 and '7, it will be seen that from the outer end portion of the finger 22 projects a lug 23 which bears against the lower portion of the flange I4 as the disc I is turned and by contacting with a tooth or abutment 24 struck inwardly from the flange M, will serve to limit rotation of the disc in either direction. Therefore, proper registration of the slots l6, l! and I8 will be assured and also rotation of the discs relative to each other in a closing direction will be limited.

When this device is in use, the disc I is grasped by holding its flange [4 between a thumb and one or two fingers of one hand and by grasping the knob 3 of the mandrel between fingers of the other hand, the mandrel and disc 1? may be rotated relative to each other in a direction which will dispose the slots of the three discs in alignment as shown in Figure 2. A look of hair can then be drawn forwardly through the aligned slots and turning motion then imparted to the mandrel to rotate the discs 8 and 9 and cause the slots to be closed and the lock of hair firmly held. This lock of hair is then coiled about the mandrel by use of a winder or in any other desired manner after which it will be covered with a wrapper dipped in chemical and thrust into a heating element of a permanent waving ma" chine. It will, of course, be understood that the hair can be first engaged through the aligned slots and coiled about the mandrel after the slots have been closed or the hair coiled about the mandrel and then engaged through the slots and the discs I turned to close the slots. This is optional with the operator.

The form of curler illustrated in Figures 8 through 15 is in many respects similar to that previously described and has a mandrel 25 formed with a turning head 26 at its outer end and a reduced rectangular neck 2'! at its inner end. The lock carried by the inner end portion of the mandrel is of a different construction from that shown in Figures 1 through '1 and consists of a housing 28 having upper and lower walls 29 and the lower wall carrying a marginal wallor flange 5i which is reduced in thickness to form a seat 32 against whichthe wall 29 bears and extended inwardly as shown in Figure 14 to overlap the disc or wall 28 and retain it in engagement with the marginal wall of the housing. Between the walls 29 and 38 of the housing is located a disc 33 formed with a rectangular opening S to receive the neck of the rod or mandrel and this disc is firmly fixed upon the neck to prevent movement of the rod outwardly through the opening 35 formed in the disc or wall 29. Therefore, by holding the housing and imparting rotary motion to the mandrel, the disc 33 may be rotated within the housing and the finger 3G3 moved across from the position shown in Figure 12 tothat disclosed in Figure 13.- When the disc 33 is cut to form the finger 35:, there is also provided a slot 39 adapted to register with the slots 3'! and .38 in order that hair may be engaged through the lock prior to movement of the disc to the position shcvm in Figure 13 and in order to limit rotation of the disc within the housing, there has been provided a pin to which projects inwardly to engage abutments 4! and :12 corresponding to the abutments 23. Since the slot 39 has a portion extending about the disc and reduced in width towards its inner end and the slots 31 and 38 have side extensions 31 and 38, hair wil be wedged in these portions of the slots and firmly gripped.

' The operation of this form of curler need not be described as it is similar to that of the device illustrated in Figures 1 through '7.

The curler illustrated in Figures 15 through 21 also has a mandrel or rod 33 carrying a lock o at one end, but the lock is quite different in its construction from those previously described. In this embodiment of the invention, the lock consists of a housing 45 having an upper wall is which fits within the marginal wall rising from the bottom of. the housing. A flange 68 projects upwardly from margins of the upper wall 46 and about this flange is formed a bead 49 which rests against the wall 'll. The inner end portion. of. the mandrel. 43 extends through an opening so formed centrally oi the wall 46 into the housing and the end of the mandrel termihates in a squared neck El which engages through a rectangular opening 52 formed in the hub 53 of a latch By referring to Figures 20- and 22, it will be seen that the latch is formed with a longitudinally curved bill 55 extending circum ferentlally of the housing in radial spaced relationto the rod.

An opening 55 is formed centrally of the wall 45 of the housing and through this opening ispassed a screw which is screwed into a socket 58 formed axially of the rod and has'its head overlying portions of the hu 53 about the neck 5! to firmly hold the latch upon the neck and prevent the rod from slipping out of the lock.

A look of hair is to be passed through the housing similar to the manner in which hair is drawn through the lock previously described and in order to do so, the bottom 45 of the housing and its upper wall or cover Gd have been formed with aligned slots 53 and 59. At one side of these slots, the marginal wall 4? is cut away to receive the hinge car 69 of a keeper 6% through which extends a screwor pivot pin 62 carried by hinge oars t3 and 64 formed upon the bottom and upper walls, and, therefore, the keeper will be pivotally mounted for swinging movement into and out of a closed position as shown in Figures 7 and 18. The marginal wall of the housing is also cut away at the opposite side of the slot to permit the bill 65 of the keeper to swing 'inwardl,y and between its hinge ear 59 and bill 65, the keeper is formed with side flanges 56 between which ongage the bill of the latch when the latch is moved into locking engagement with the keeper.

When this form of curl-er is in use, the lock of hair is passed through the slots of the housing and its cover or upper wall and coiled. about the mandrel as previously described. In order to se cure the hair in position through the lock, the keeper is swun inwardly towards a closed position after the hair has been engaged through the slots 58 and e The housing and mandrel can 'hen be turned relative to each other in a direction to move the bill of the latch across the aligned openings and as this movement takes place, the bill 55 will overlap the bill 650i the keeper and exert a cam action which will force the keeper inwardly until the hair is very firmly gripped between the keeper and inner ends of the slots of the housing.

Since the free end portion of the bill 55 engages between the side flanges 65' of the keeper, transverse movement of the latch and keeper relative to each other will be prevented andthe keeper will be forced inwardly towards a closed position without danger of side strain which might bend or break the pivot pin. When the rod and housing are turned in anopposite di rection relative to each other, the keeper will be released and may be swung outwardly to an open'orinoperative position, thereby releasing the hair and permitting it tobe drawn outwardly end is enlarged asjshown at Si to form ahead bored to provide a socket 68 communicating with a passage 69 extending axially through the rod fromthe socket to the upper end of therod. The lower end portion of the socket is addi tionally enlargedin diametenl thereby forming a seat to rotatably receive a. neck H projecting upwardly freonv the center of the .top or upper wall E2 or the housing #3 forming the body por tion of a lock M corresponding to the lock 44. The cover or upper wa11'12 rests upon the marginal wall of the housing where it is held in place by a screw 15 engaged through hinge ears 7'! and T8 and serving as a pivot pin for a keeper 19 corresponding to the keeper 5i. A flaring flange ormarginal wall all projects upwardly about margins of the cover or upper wall 12 with its ends terminating at opposite sides of a slot 8! formed in this cover and from one of the side arms or wings 82 of the keeper 79 extends a lip 83 forming a continuation of the wall 80 when the keeper is swung inwardly to the closed position shown in Figures 25 and 27.

.By referring to Figure 27, it will be seen that when the keeper is in a closed position, it moves into the slot 3! of the cover 72 and also into a corresponding slot 84 formed in the bottom of the housing 13. A key or rod 85 carrying a latch 86 at its lower end which is firmly fixed to the same extends through the hollow stem or mandrel and by' rotating the stem the bill 8? of the latch may be moved into and out of position to overlie the keeper and secure the same in a closed position with a lock of hair gripped between the keeper and inner end of the slot formed inthe upper wall or cover and bottom of the housing. The rod or stem 85 is of such length that it'projccts beyond the upper end of the rod or stem and upon this protrudinglupper' end of the rod which is squared as indicated by dotted lines in Figure23, is applied a finger engaging element 38 which is removable in order that the rod may be slid longitudinally through the mandrel when it is necessary to remove the mandrel. Wings 89 which'are preferably four in number project radially from theupper end portion of the rod to permit this rod to be readily rotated when the lock 14 is held between a thumb and finger of one hand andthe wings gripped between a thumb and finger of the other hand, and in order to control rotation of the rod, there has been provided a coiled spring 535 firmly seated in the collar ll which serves as a bearing for the lower end-of the rod and this spring extends into'the socket 68 with its free endin contact withwalls of the socket. .133 this arrangcn'lent, the rod or stem may be readily rotated in one direction about the stern and collar H but if it is attempted to turn the rod in an opposite direction the sharp free end of the spring will bite into walls of the socket and prevent rotation in this direction. Therefore, the rod can only be turned in one direction and a lock of hair engaged through the lock it will be coiled in a proper direction about the rod. A tongue 9! formed of thin sheet metal extends longitudinally of the rod and this tongue which .is curved transversely in order to fit closely about the rod as shown in Figures 24 and 25 is pivotally mounted at one end to the rod a short dis-- ,tance from the inner ends of the wings 89 as shown at 92. Therefore, when a lock of hair is to be coiled aboutthe rod, its free end'portion may be first engaged between the rod and the tongue 9i andfirmly gripped by the tongue during a coilingoperation. Therefore, the hair will be firmly held andprevented from slipping during or after it has been coiled.

When this form of curler is in use, a lock of hair is passed through the slots 84 and 8!, of

the cover 12 and housing 13 after the keeper I9 has been swung towards the closed position shown in Figure 5, the head or finger engaging element 88 of the stem will be grasped and rotary motion imparted to the stem to swing the bill 8! of the latch toward the keeperand cause the bill to move to overlapping engagement withthe keeper and force the keeper tightly into place within the housing of the lock. The free end portion of the lock of hair is then engaged between the rod and the tongue 9! and by grasping the wing the rod can be easily rotated in a counterclockwise direction and cause the lock of hair to be coiled tightly about the rod. Either a croquignole coil or any other type desired may be formed by properly guiding the lock of hair during a curling operation.

The curler illustrated in Figures 29 through 35, has a mandrel 9! formed of metal or any other suitable material and at the lower end of this mandrel is provided a lock {72 for connecting the mandrel with a lock of hair to be curled. The lock has upper and lower plates 93 and 94, the plate 83 being formed with a depending hub terminating in a squared neck $6 received in a square opening 9i formed centrally of the plates or discs 9 This hub 85 retains the plates spaced from each other and since the plate or disc 54 is carried by a squared neck, the two plates will turn as a unit. A screw 98 serves to hold the lower plate in place about the neck and by being screwed into a threaded socket 953 formed in a stem Ebb, serves to connect the stem with the upper plate. This stem fits into a seat or socket l9! formed centrally of the upper plate an about this socket is formed an annular groove Hi2, serving as a seat for the inner end of the mandrel and when this mandrel is seated in the annular groove, frictional engagement will take place and cause the two plates to turn with the mandrel. By exerting pull upon the mandrel, it may be readily separated from the lock and drawn away from the same to release a coil of hair after a curling operation has been completed.

Referring to Figures 33 and 34, it will be seen that the stem IE6 is received in a pocket I03 formed longitudinally of the mandrel from its inner end and this stern slides through a bushing use which fits tightly within the pocket of the mandrel and serves to guide sliding movement of the mandrel toward and away from the lock. The bushing also serves to engage a head Hi5 carried by the stem and prevents sliding movement of the mandrel away from the look beyond the position shown in 34. By this arrangement, a lock of hair may be coiled tightly about the mandrel with the mandrel in the position shown in Figure 33 and after a curling operation is finished, the mandrel may be drawn through the coil of hair to the position shown in Figure 3e, thereby releasing frictional grip of the hair and permitting it to expand suiliciently to break its grip and allow the mandrel to be slid out of the curl.

,If so desired, the mandrel may be directly secured to the upper plate as previously shown and described instead of being mounted for movement towards and away from the lug.

The plates 93 and 94 cooperate to form a housing between which a keeper IE6 is pivotally mounted for movement from an opened position shown in Figure 32 towards a closed position shown in Figure 30, in which the keeper extends 'ciroumferentially of the housing across hair receiving recesses 10'! and I68 cut radially of the plates or discs and having side extension [09 and H0 into which the hair is to be forced and firmly gripped when the device is in use. When a lock of hair is engaged through the opposed hair receiving recesses of the plates or walls of the housing, the keeper is to be moved inwardly and forced into tight gripping engagement with the hair. In order to do so, there has been provided a band or collar i I l which fits snugly about the housing in contacting engagement with marginal edges of the upper and lower walls and referring to Figures 33 and 34, it will be seen that this collar or band is formed with an inwardly projecting, circumferentially extending lip H2 which projects into the space between these walls and prevents movement'of the collar out of its proper engagement with the housing. An upstanding marginal flange I !3 carried by the upper wall or plate also bears against the collar and assists in retaining the collar in proper engagement with the two walls and guiding rotation of the collar. in spaced relation to each other a distance slightly greater than the width of the hair receiving recess of the housing in order that easy access may be had to the hair receiving recess when fitting a lock of hair into the same.

Referring to Figures 30, 31 and 32, it will be that as one end of the band, the lip H2 and face of the hand are cut straight across iagonally to form an undercut cam surface I M, whereas at the other end of the collar the lip is gradually reduced in width to form a cam surface l 85. By this arrangement, a lock of hair may be engaged through the recesses of the plates 33 and 84 and by holding the band or collar with the thumb and fingers of one hand and turning the mandrel with the other hand in the direction indicated by the lower arrow in Figure 31, the keeper or tongue Hi6 will be guided inwardly by the cam surface H5 and moved inwardly across the hair receiving recesses to a position in which the lock of hair will be forced into the end portions H39 and H0 of the recesses and firmly gripped.

When the mandrel is rotated in the opposite direction indicated by the upper arrow in Figure 31, the free end of the keeper which is bevelled as shown at H6 will make contact with the bevelled end face H4 and be guided outwardly towards the opened position as shown in Figure 31 and finallymoved to the fully opened position shown in Figure 32. By this arrangement, the tongue or keeper moves automatically into and out of a position across the hair receiving recesses and the device can be very easily engaged with or disconnected from a lock of hair;

Insofar as the croquignole winding device, as illustrated particularly in Figures 23 to 28, inclusive, is concerned, the important feature of the device is the linking together'of a lock directly on the shaft, rod or mandrel upon which the croquignole winding of the hair is accomplished. Whereas, heretofore it has been necessary to utilize a separate locking element into which the hair curling rod is inserted in order to lock the hair on the rod and the rod in position with respect thereto, I have provided a device in which there is a combination lock and hair curling lock for croquignole winding. Such a combination device saves time, labor and expense in operation and will eliminate the possibility of burning the scalp, which quite frequently occurs through the use of the well known separable locking elements used on hair curling mandrels or rods.

Ends of the collar or band terminate From the foregoing description of the con.- struction of my improved device, the method of applying the same to use will be readily under= stood. It will be seen that I have provided a simple, inexpensive and eficient means for carrying out the objects of the invention and while I have particularly described the elements est adapted to perform the functions set forth, it is ob us that various changes in form, proportion and in the minor details of construction may be resorted to, without departing from the spirit or sacrificing any of the principles of the invention.
