CURNG-IRON.

No. 917,580. Y

Curling-Irons, of which the following 'is a specification.

My invention relates to improvements in curling irons, and its primary object is to provide a device of this character having means by which the mandrel may be rotated in a direction to curl the hair about the same, or in a direction to free the same from the hair. t

A further object of my invention is the provision of a curling iron wherein certain Vmovements of the mandrel rotating member swings the mandrel into inoperative position, that is, in position to permit the ha'1 to be initially curled about the mandrel, a further operation of the rotating member permitting the clamp to be returned to inoperative position, that is, in position to preventl the uncoiling of the hair from the mandrel.

A still further object of my invention is the Y provision of a4 curling iron which is simple, durable and eilicient, and which may be manufactured and sold at a comparatively low cost.

TvVith the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter fully described, claimed and illustrated in the accompanying drawing, wherein:

Figure 1 is a view in side elevation of a curling iron constructed in accordance with my invention, the handle being in longitudinal section. Fig. 2 is a top plan view thereof. Fig. 3 is a sectional view taken on a plane extending through portions of the shank of the mandrel and the mandrel rotating member. Fig. 4 is a sectional view taken on the plane indicated by the line t-a of Fig. Q1, and Fig. 5 is a view in elevation of a portion of the mandrel shank, the mandrel rotating member being in section.

Referring to the drawing by reference numerals, 1 designates the handle, 2 the mandrel, and 3 the clamp of my improved curling iron.

The handle 1 may be constructed of wood, metal or any other material suitable for the purpose, and is provided with a bore a which Specification of Letters Patent.

extends longitudinally thereof. The bore l extends through the inner end of the handle 1 and communicates with a reduced socket 5 formed in the outer closed end of the handle, an opening 6 extending from the socket 5 through the outer end of the handle. The inner end of the bore et is closed by means of a plug 7, which has threaded engagement with the wall of the bore and which is provided with an opening S. The opening 8 and the socket 5 form bearings for the reception of the shank 9 of the mandrel Q, whereby the mandrel is rotatably mounted on the handle. The mandrel is prevented from longitudinal displacement by means of an extension 10 which passes through the opening 6, and a nut 11 which has threaded engagement with the projecting end of the extension.

The shank 9 is preferably formed inA tegrally with the mandrel 2, and is provided for a portion of its length with a spiral. screw comprising left grooves 12 and right grooves 13. The grooves of the spiral screw communicate with an elongated groove 14 formed in the upper surface of the shank 9 at a point adjacent its union with the mandrel 2. An annular member 15 encompasses the shank 9 of the member and is mounted in the bore l for longitudinal movement. This member is provided with a lug 16 which lits and moves in the grooves of the spiral screw, whereby the reciprocation of said member will impart rotary movements to the mandrel.

The member 15 is provided with a shank 17 which passes through an elongated slot 18 formed in the handle 1, said slot opening out through the inner end of the handle to permit the application or removal of the member. lThe opposite end of the slot is provided with a lateral branch 19, and said slot is increased laterally in both directions at a point adjacent the inner end of the handle, as at QG. The shank 17 is provided with a head 21 which is disposed above the handle 1 and which provides means by which the member 15 may be reciprocated. The movement of the member outwardly, that is, in the direction of the outer end of the handle 1, with the lug 16 in the right groove of the spiral screw, will rotate the mandrel 2 in a direction to coil the hair located on one side of the head about the same, and the movement of the member in the same direction with the lug in the left groove ot' the spiral screw will rotateY the mandrel in a direction to coil the hair located on the opposite side of the head about the same. r1`he inward movement of the member 15 will rotate the mandrel 2 in a direction to free the same from the coiled hair. The member 15 is held in the extremities of its inward movement, which is its normal position, by'means of an expansible coiled spring 22, which is mounted within the bore 4 about the shank 9 ot' the mandrel, and which is interposed between the closed end of the bore and the member. As the spring is compressed during the movement of the member to rotate the mandrel 2 in hair curling direction, the member will be automatically returned to its normal position when released. l t should be thus apparent that the mandrel 2 will be autoniaticalljT rotated in hair uncurling direction, thus rendering it only necessary to manually operate the member when it is desired to rotate the mandrel in hair curling direction. When the member 15 is in its normal position, the lug 16 occupies the groove 14, and the movements of the member to carry the lug out of this groove into one of the grooves of the spiral screw or to return the lug fully into the groove 14k from one of the grooves of the spiral screw, are inoperative, that is to say, such movements do not rotate the mandrel 2. In other words, the initial movement of the member 15 in a direction to rotate the mandrel in hair curling direction and the nal movement of the member in the direction to rotate the mandrel 2 in hair curling direction, are inoperative. The lateral enlargement 20 of the slot 18 permits the lug 16 to be directed into the right or left groove of the spiral screw, and the lateral branch 19 in said slot permits the member to be held in position to secure the iron against hair uncurling motion, the shank 17 of said member being adapted to be directed into said branch when it is desired. to secure the member against such movement.

The clamp 3 is arcuate in cross-section and is pivotally secured to the mandrel 2 through the medium of a pivot 23. The clamp is provided in rear of the pivot 23 with an extension 24, presenting an upwardly inclined face 25 and a downwardly inclined spring 26. The free end ot' the spring 26 engages the mandrel 2 and normally holds the clamp 3 in closed position. The extension 24- is provided at a point intermediate its inclined face 25 and the spring 26 with a seat 27. The member 15 is provided with an arm 28 which projects therefrom in the direction of the extension 24 and which is provided with a downwardly curved lip 29 which normally overlies the inclined face 24 of said extension.

j Upon the initial movement oi"- the member 15 in a direction to rot-ate the mandrel 2 in hair curling direction, the lip 29 moves in contact with the inclined face 24 and throws the clamp 3 into opened position, that is, in

position to permit the hair to be initially coiled about the mandrel 2.` Just previous to the members reaching the limit of its initial movement, the lip 29 engages inthe seat 27 and holds the clamp 3 in opened position. A further movement'of the member withdraws the lip 29 from the seat 27 and moves the lug 16 into one ofthe grooves of the spiral screw, the withdrawal of the lip 29- from the seat 27 permitting the spring 26 to move the clamp into and hold it inits closed position, in which position it secures the initially coiled hair about the mandrel.

A. further movement of the member 15 will I over the spring 26, throwing the clamp into Y opened position. A further movement of the member will direct the'lip into the seat 27, whereby to secure the clamp in opened position. When the clamp is in this position the iron may be readily withdrawn from the curled hair. When it is desired to permit the clamp 3 to be closed, the member 15 is operated to move the lip 29 out of the seat 27 and position it in advance of the inclined face 25, whereby the initial operation of this member will swing the clamp into its opened position.

A rest 80 of substantially Ult'orm is pivotally secured at its ends to the handle 1 at a point adjacent its inner end, said rest providing means by which the curling iron may be supported above the flame of an alcohol lamp. When it is desired to support the iron above the llame of a lamp or gas bracket, the member 15 is moved to swing and hold the clamp 3 in its opened position, after which the iron is placed upon the upper edge of a lamp chimney orrgas bracket globe, the angular relation of the clamp to the mandrel preventing the iron from rotating on the lamp chimney or gas bracket globe.

From the foregoing description taken in connection with the accompanying drawing, the constructionand mode of operation of the invention should be understood withouta further extended description.
