Thus either flange 2I or 22 of either which receive, between them, a pair of integral facing member may be disposed along the inner 55%' sides of the jaws 5 and 6 for gripping cooperation with the hair, and after such use of one flange, the facing member may be removed and reversed to present the other flange along the inner side of the jaw. The outer surfaces of the iianges 2| and 22 of each facing member may be ribbed or grooved as shown in Figure 1.

A heat insulating strip 25, of felt or other suitable material, is secured to the bottom of each of the facing members 2li preferably by means of parallel lines of stitching indicated at 25. Of course these strips 25 may be secured to the members 25 in any other suitable or preferred manner. The strips 25 are substantially coextensive with the facing members 20, and their opposite ends project endwise beyond the members 20 to underlie substantially the entire length of each jaw 5 and 5. The relatively flat form of the channel-shaped jaws 5, together with the rounding of the upper and lower edges of the backs of these jaws, permit the facing members to be applied and removed sidewise and then turned to the position shown, although the form and yieldability of the members 2B will permit these members to be applied from the bottom and directly to the desired position and similarly removed.

Disposed within the channel sections of the jaws 5 and 5 are springs 28 having intermediate portions 29 lying along the open inner sides of the jaws. The inturned ends 3l! of the springs 29 terminate in longitudinal extensions which are adapted to be sprung between and into interlocking engagement with prongs 32 pressed in from the back walls of the jaws 5 and '5. The springing of the ends of the springs 28 between and into engagement with the prongs 32 secures the springs 28 removably in position within the jaws and bows the intermediate portions 29 outwardly and places the same under tension. These bowed intermediate portions 29 of the springs 28 press the inner side flanges of the facing members 25 inwardly and provide an effective gripping action upon the bunched strand of hair placed between the jaws, as indicated at 34. The springs 28 maintain an effective gripping action of the members 20 upon the hair at all times and increase the life of the members 20, particularly along the locations where the hair is gripped. And the life of these members 29 is further increased by the reversibility of the same upon the jaws 5 and 6.' The springs 23 preferably bow the inner sides of the facing members 20 to con- Vex form along the locations where the hair 34 is gripped, as shown at 35 in Figure 2.

The particular curler I3, selected for illustration, is ofthe type more fully disclosed in my prior patent, No. 1,862,721, patented June 14, 1932. Suice it to say that this curler comprises the metal spool or reel 35 of circular section, diminishing in diameter from its opposite ends toward the center, and a saddle-like retainer 31 pivoted to one end of the spool at 38. A iingerpiece 39 is provided at one end of the spool for turning the same, and the opposite end of the spool has teeth '46 which cooperate with a spring pawl 42 to prevent unwinding of the spool.

The spring pawl 42 comprises a spring strip turned in beneath the bottom of the jaw 6 and secured thereto as by means of a rivet 43. A prong 44, struck in from the spring strip, engages the teeth and holds the spool against unwinding. The upper end of the spring strip is rounded or turned at 45 to be actuated by the operators finger for the purpose of releasing the prong 44 from the teeth 4U. A small lug 46, integral with the journal part IB, forms a stop for limiting the releasing action of the spring pawl.

The device for closing the jaws and locking the same in closed position comprises a lever pivoted for free swinging movement at one end at 5l between the tongues I4 of the jaw 5. The lever 5D comprises a pair of superposed arched pieces between the pivoted ends of which a Washer 52 is provided. A latch 53 is pivoted at 56 between the free ends of the arched pieces constituting the lever 5D, and this latch 53 preferably has a shoulder 54 which, by engagement with an integral stop 55 turned down from the edge of the top piece of the lever 50, limits swinging movement of the latch in a cl`o`ckwise direction with respect to the lever 50 as viewed in Figure 2. The pieces constituting the lever 50 have lips 5U turned in, or the pieces are otherwise formed to bear against the latch member 53 to prevent free turning of the latch with respect to the lever. As a result, the latch 53 and lever 5U swing substantially as a unit about the pivotalll connection at 5l with the jaw 5, and until the latch engages the other jaw, whereupon the latch and lever swing about their respective pivots, as will appear. The latch 53 has a relatively short projecting nger 51 provided with a rounded cam edge 58 which has a depression 59. 53 also has a finger-piece '60 turned at substantially right angles to the pivoted part of the latch and preferably elongated to give the operator a considerable mechanical advantage in closing and locking the device.

Further, to facilitate ease of operation of the device, the part on the jaw G for cooperation with the jaw closing and locking latch 53 is in the form of a roller 62. This roller 62 is mounted between integral tongues 53 projecting endwise from the top and bottom flanges of the channel section of the jaw 6 for free turning movement upon a pin 64 xed in the tongue B3 as by heading one end and riveting over the opposite end of the pin.

With a bunch of hair between the jaws 5 and 6 as shown in Figure 2, the device is closed by applying the nger to the finger-piece 69 and pressing the same in the direction indicated by the arrow in Figure 2. This swings the latch 53 and lever 50 as a unit, or at least substantially as a unit, about the pivot 5I until the finger 51 takes over the roller 62. Thereupon, as the ngerpiece is pressed further in the same direction, the lever 50 continues its swinging movement in a counter-clockwise direction about the pivot 5l and, at the same time, the latch 53 swings in a counter-clockwise direction about the pivot 58. The resulting action gives the operator great mechanical advantage and forces the jaws 5 and 5 positively to closed position with great force. The roller action, due to the engagement of the roller 52 with the latch 53, further facilitates the closing and locking action, and as the pin 64 moves into or past dead center a-a (Figure 3), the jaws 5 and 6 are locked positively in closed position.

I do not intend to be limited to the precise details shown or described.
