Sterling, Chicago, Ill. Application April 15, 1935, Serial No.'16,'314 6 Claims. (C‘l. 132-36.1) This invention relates to a hair-waving or pro- tongues» 9 offset to lie closely together and eX tector clamp for application to the hair during the process of waving the same, and may be characterized as an improvement upon the hair 5 waving clamp disclosed and claimed in my co- pending application, Serial No. 748,992, filed October 19, 1934. One of the features of the present invention is the provision of improved resilient facing mem- flanges of the jaw 6. The tongues 8 and 9 are pivotally joined'by the pivot '1, whichV may be in the form of a rivet or of other suitable or pre- 5‘ ferred form. The pivoted end of the jaw 6 has a tab il which is widened and turned up and notched at I2 to receive and support rotatably the adjacent end of the curler spool, indicated 10 bers for the jaws of the clamp, and particularly in its entirety at I3. an improved spring arrangement for the meeting surfaces of these members whereby to improve the action and increase the life of these` surfaces, particularly along the location where the bunched 15 strand of hair is gripped. Another feature is the provision of an improved mounting for these resilient facing members, which mounting will permit convenient removal and reversal of the facing members on the jaws The back of the jaw 5 terminates short of the free end of the jaw, leaving the projecting tongues I4. The upper tongue I4 is elongated and folded back and turned up at I5 to form one side o-f the journal for the adjacent end of the curler I3. »lo The back of the jaw 6 likewise terminates short of the free end of the jaw, and the adjacent end of the top flange of the channel section of this jaw is widened, turned up at I6, and notched at 20 of the clamp. , , between; 35 . ` Y . f ber or the like, and are of channel-shaped seo tion to embrace and snugly grip the jaws 5 and ~ 6 as shown. Referring to the drawing, the clamp selected for illustration comprises a pair of elongated jaws 5 and 6 pivotally connected together at one/'end at ‘I and provided, at the opposite end, with a 45 device for closing the jaws and locking the same in closed position. This device is similar tothe jaw closing Aand locking device disclosed and claimed in mycopending application, Serialn No. 748,992, filed October 19, 1934. 50 In the illustrated embodiment, each jaw 5 and jaw (Figure 5) to hold these flanges in proper Spafëed relß’ßÍOflj 3'5 . The facing members 29 are fûi‘med 0f resilient material. such as relatively live or yielding rub Figure 51s a detail section taken' on `the line 40 5--5 of Figure 2. 11G end of the curler I3, the upturned journal part I5 on the jaw 5 constituting the other part of thisjournal, and when the jaws 5 and 6 are- closed, holding the adjacent end of the curler I3 against lateral displacement from the journal part I6. 25 Short of its free end, the bottom flange of the channel section of the jaw 5 has an integral lug I8 (Figure 4) turned up and abutting the top flange of the jaw 5 to hold the top and bottom flanges of this `jaw in proper spaced relation. 30 Similarly, the bottom flange of the jaw 6 is pro-A vided short of its free end with an integral lug I9 turned up and abutting the 130D Íîange 0f this' Figure 3 is a fragmentary top plan View, partially in section, With- the jaws in closed position; Figure 4 is a detail section taken on the line 4~-4vof Figure 2; and ` I'I to receive and support rotatably the adjacent 20 Another feature resides in an improved mounting and stop arrangement for the spring paw] for holding the hair-waving spool against unwinding. Further features and the advantages of the 25 invention will be apparentfrom the following de-tailed description, taken in connection with the accompanying drawing, in which: Figure 1 is a side elevational View of a hairwaving clamp embodying the present invention, 30 showing the waving spool applied thereto; » Figure 2 is a top plan view, partially broken away and in section, showing the jaws in open position and a bunch of hair positioned there- A tending out laterally from the top and bottom ~ When the facing members are in 40 DOSÍÈÍOIl U-D'Oïl the .laWS 5 and 6, the bottoms' 0f these facing member-'ä lie 310119 the under Sides of the bottom flanges of the respective jaws 5 and 6, and the upstandin'g side flanges 2| and 22 lie along the- backs and along the open inner sides 45 respectively of the jaws 5 and 6. Integral flanges 23, turned inwardly from the upper ends of `the side flanges 2| and 22, engage the upper sides of the jaws 5 and 6 and hold the facing mem bers in place upon the respective jawv members. 56 6 is in the form of a sheet metal stamping of The channel section and yielding character of channel section. At its pivoted end, the chan- \ the members 20 permit convenient removal and nel section of the. jaw 5v has its top and bottom flanges extended to form projectingV tongues 8 55 ‘which receive, between them, a pair of integral reversal of these facing members on the jaws of the clamp. Thus either flange 2I or 22 of either facing member may be disposed along the inner 55%' 2 2,132,764 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| 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 and 22 of each facing member may be ribbed or grooved as shown in Figure 1. same in closed position comprises a lever 50 pivoted for free swinging movement at one end A heat insulating strip 25, of felt »or other suit able material, is secured to the bottom of each 10 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 coex 15 tensive with the facing members 20, and their opposite ends project endwise beyond the mem bers 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 20 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 25 these members to be applied from the bottom and directly to the desired position and similarly re moved. Disposed within the channel sections of the jaws 5 and 5 are springs 28 having intermediate 30 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 interlock ing engagement with prongs 32 pressed in from 35 the back walls of the jaws 5 and '5. The spring ing 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 in crease the life of the members 20, particularly along the locations where the hair is gripped. 50 And the life of these members 29 is further in creased 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 55 is gripped, as shown at 35 in Figure 2. The particular curler I3, selected for illustra tion, is ofthe type more fully disclosed in my prior patent, No. 1,862,721, patented June 14, 1932. Suñice it to say that this curler comprises the 60 metal spool or reel 35 of circular section, di minishing 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 iinger piece 39 is provided at one end of the spool for 65 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 70 secured thereto as by means of a rivet 43. A prong 44, struck in from the spring strip, en gages the teeth 40 and holds the spool against unwinding. The upper end of the spring strip is pawl. The device for closing the jaws and locking the 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 be tween the free ends of the arched pieces consti tuting 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 sub stantially as a unit about the pivotalll connection at 5l with the jaw 5, and until the latch en gages the other jaw, whereupon the latch and lever swing about their respective pivots, as will appear. The latch 53 has a relatively short pro jecting ñnger 51 provided with a rounded cam edge 58 which has a depression 59. The latch 53 also has a finger-piece '60 turned at substan . tially 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. 35, 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 ñxed 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 ap plying the ñnger to the finger-piece 69 and press ing 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 ñnger piece 60 is pressed further in the same direction, the lever 50 continues its swinging movement in 55 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), 65 the jaws 5 and 6 are locked positively in closed position. _ I do not intend to be limited to the precise de tails shown or described.
