Claims. (Cl. B52-36.1)
This invention relates to a protector clamp for use in permanent waving and has for its principal object to provide a device of this kind having at the same time greatly increased erably composed of wood of high heat insulating value and spaced from the bars lil and I I by spacing washers 28 and 29.
Cooperating with the clamping bars IU and ll 5 strength and greatly reduced weight. at the right hand end as seen Figs. 1 and 3 is a 5 More specifically, objects of the invention are hinge indieated generally by the numeral 3U and the provision of clamping bars or jaws of im- Comprising relatively movable portions pivoted proved cross section and improved hinge contogether by means of the pivot pin 3l. The hinge structions, as well as improved gripping latch conportion 32 is preferably a unitary tiing 0i a jo struction. maximum thicknes equal to the thickness of the l0 Other and more limited objects will be in part flange i3 and is milled out from an integral piece apparent and in part pointed out in connection of metal to form spaced tongues 33 and 315 which with the accompanying drawing wherein Fig. 1 are received snugly in the spaces formed between is a plan View of a protector clamp embodying the the Web il and the edjeeent flanges- The elei; invention, that is, a view looking toward the side ment 32 is provided with a projection 35 extendl5 of the clamp which is opposite the scalp when the ing ai right angles t0 the On'eueS 33 and reCeV- device is in use; Fig. 2 is an edge view or elevation ing the pivot pin The prOJ'eetOn 35 iS preferof the device shown in Fig 1; Fig, 3 is a View ably of the same thickness as the web l1 and similar to Fig. 1 but showing the parts in open thus is. of a thickness equal to the space between position; Fig. 4 is an end elevation and Figs. 5, the elements 33 and Se. it is to be understood 20 6 and 7 are sections corresponding substantially theft lie Cerner Dertien Of Jlle element 32 iS 0f e to the lines '.i--s and 1 1 respectively of thickness equal to the sum oi? the thicknesses of Fig. 1 the two elements 33 and Se and the element 35.
Referring now tothe drawing, the numerals l0 The Oli-her Dertien Of tbe hinge 3@ iS mede up 0f r and "II indicate generally the clamping bars or two elements, one of which 36 is applied to the up- 25 0 jaws whose resistance to bending is the most imper surface of the clamping bar le, as Seen in Fie. portant strength factor required in a device of 1, the engeS i3 and i4 0f Such ber being Cul? away this kind. -I prefer to make the bars l0 and Il to receive the element 36. The element 36 is of'a light weight metal of high strength, prefer- DrOVded. With a tengue 3l eXenClng inte the g, ably duraluminum. Other metals, however, can SIJeCe between the lengee i3 and Ul and lying in 30 d be used with more or less good results. I prefer Contact with the web l2 and secured thereto as by to form the. bars or jaws lu and 1| by extrusion rivet 38. Preferably the web l2 extends to the since a fairly complex cross sectional shape is eX'rerrle rient 0f 'Clie element 35 eS Clearly indiv desirable and the extrusion method lends itself Gered in Fig 2.
V most readily to the production of suon shapes The element te is provided with a cradle por- 35 "a while at the same time preserving the inherent Gien 39 eXtendrlg at right angles 150 the plane 0f strength of the metal. The fundamentai shape the jaw le and carrying a pawl le for reception of the bar lll is that of an I-beam having a, web of the usual winding mandrel. Underneath the l2 and an ente;1 flange I3 of Simple form and a, element 3e and parallel therewith is an element 40 gang@ |4 having integral portions g5 forming a lll which cooperates with the element 35 to com- 40 slightly tapering channel for the reception of a plete the Dertien 0f the hinge member Secured deformable gripping element I6, preferably rubi0 the J'eW l- The element @l iS lJrOVded With ber. The jaw H is of the same fundamental cross a tongue r2 extending into the space between the section, although more complex, being made up flanges i3 and L on the underside. The tongues of a central web Il and an outer flange la ter- 3l and 42 are secured to the web l2 by a suitable 45 minating in a, Curved portion I9 and an inner rivet 33 While the tongues 33 and 34 are Secured flange 20 having inwardly extending portions to the web Il by a rivet dil. It should be noted 2l forming a channel for the reception of a secthat these tongues ft snugly in the SDeCe between ond deformable gripping element 22 similar to the arlges against the webs and connect the the element I6. The uppermost portion of the hinge elements With the Clamping jeWS in e Very 50 ange 2l] extends upwardly toward the curved effective manner, the rivets 38 and ed being relied portion i9 as indieated at 23, The purpose of upon merely to hold the parts in assembled relathe elements I9 and 23 is to form a groove for the tien but not taking any eensflerable amount of Areception of a bead at the edge of a hair treating stress when the clamping jaws are subjected to pad. This method of attachment of hair treating bending force at the time they are beine closed 55 l pad is similar to that shown in United States on astrand of hair.
Patent to Spaeth No. 1,746,018. i At the other ends of the clamping jaws Il] and Secured to the web portions l2 and l'l of the il is a latch indicated generally by the numeral clamping bars i0 and ll, by means of screws 24 45. The flanges 0f the Clamping ber il are Cut and 25, are heat insulating strips 2B and 21, prefaway to leave a projecting web portion as indi- 6o cated at d6. The jaw i0 similarly has the flanges cut away to leave a projecting web portion as indicated at 41, the outside face of the portion 4l being curved as indicated at 48 to provide a seat for the latching cam. Pivoted to the portion 46 by means of pivot pin 49 is the latch element which is made up of a channel shaped element and a latching cam 5i controlled by the hand piece 52. The element 5d has upper and lower plate like elements 53 and Eli which'receive the projections 4S and di? therebetween. The portions 53 and 54 are integral with a connecting portion 55. The channel portion 50 also carries an integral cradle element 56 adapted to cooperate with the crade element 39 to support the winding mandrel.
Itwill be noted that the flanges of the bars lil and l l are cut away at an angle and that the latch element 5@ has its edges adjacent to such cut away portions formed in a V-shape. This conguration makes possible the attainment of a somewhat greater eifective length for a given over-all length of the device, at the same time providing adequate strength for the latch. The cam element 5I is of a thickness substantially equal to that of the webs i2 and Il and substantially lls the space between the elements 53 and 54. I prefer to make the hand piece 52 rather narrow and of such size that it will bend, in an attempt to tighten the device on too large a strand of hair, before there is any serious danger of bending the jaws or clamping bars l5 and ii. This handle thus becomes a safety feature which protects the remainder of the clamp and in the event an operator should attempt to clamp too large a strand of hair, the damage to the device would be slight and could be repaired by the renewal of a small part.
By the use of the above construction, I have been able to secure for a given weight an inf crease in strength as great as 50% as compared to previous protector clamps with which I am familiar.
From the foregoing, it will be obvious that I have provided a protector clamp which is well adapted for its intended purpose and while I have shown and described the present embodiment, I wish it understood that I am not limited to the details of the disclosure but only in accordance with the scope of the appended claims.
Having thus described my invention, what I claim is:
