50 proved embodimentsof the-invention,vand shown;
i -'the following description;
-of Figure 6, and
forms, when the clamp is' the jaw 10, and the longitudinal edge 15 0f the jaw 10 is similarly located with respect to the concave inner surface of the jaw 9. This relationship results from the shape of the resilient member 11 which in its free position as shown in Figure'G has a formation presenting in section substantially the shape comprises substantially a three-quarter-circular cylindrical surface with tangential plane-surface forward ex-c tensions thereof. A portion of the member 11 constituting one of these extensions projects beyond their line of intersection and assembled as shown in Figure 5, an overhanging lip extending outwardly from the mouth ofthe clamp as shown at 1a of Figure 5. 7
With the clamp assembled but in its free condition as shown in Figure 5 the resilient member 11 has substantiallythe same for.- mation' as before assembly, but is somewhat expanded from its own free formation, by the jaws themselves,'to a larger radius of curvature of its cylindrical portion and produces an inward pressure of the jaws 9 and 10 against each other.
The jaws 9 and 10 may be attached to the member 11 in any convenient manner. In the form here shown, outward and backward extensions 18 and 19 are provided for the jaws 9 and 10 and attachment is made to these extensions by means of the tubular rivets 20 and 21, engaging the member 11 in holes 22 and 23, partly shown in Figure 6.
The shield 16 is attached also 21, and forms a convenient handle to be used in attaching theclamp. The shield 16 is preferably made of'fibre or other material having a relatively low conductivity for heat for reasons which will be hereinafter set;
forth The outer edge of the shield 16 is curved to give the clamp an attractive appearance and a hole 26 is provided to receive above is shown by Figures 7. and 8 of the thumb and fingers; the projecting edge 14 of Figure 5 is thenhooked over the body and a suitable movement of the shield opensthe mouth 1 17-15 of the clamp and allows pasthat the longiion the size of the bodygripped. These two "actions combine to permit the'jaws to be by the rivets sage of the body therethrough. The separation of the lips 14 and 15 is assisted by the perforated portions of the resilient member 11 so that the mid portion of the same will not beunduly flexed.
The clampin position will assume "a configuration dependingon'the size of the body. WVitht-hcclamp in operation, as in the case of- Figure ,,1, '-or Figure 4, the originally curved portion of the member 11' is expanded to a larger radius of curvature than in the free position of the clamp, whereas the originally'straight portions are bent inward to a greater or less extent, depending widely separated without straining the member 11. Also, with a comparatively large body such as 27 of Figure at the perforated end portions of the member 11 partially wrap themselves about the jaws 9 and 10 "and arethus protected against overflexture.
It will be clear also that since both the central and end portions are utilized forfiexure, the wide range of extension will not necessitate a wide variation in gripping pressure. j
The flexible connection provided between the jaws 9 and 10 permits these jaws to be moved rotatively with respect to each other independently of their translational movement of separation. The opposite flexure of the end and mid portions respectively of the member 11 results in an effective balance of forces over a considerable range. jaws'9 and 10 thus may be adjusted rotatively about such a body as 27 of Figure 4, or 28 of Figure 1, to rovi'de a greater or' less separation of the e ges 14 and 15, without affecting the stability of the clamp.
lVhen used for holdingfhair wound on a curler spindle, one size of clamp may be' used with windings of various sizes without undue variation of'holdi-ng pressure, and if the jaws in each case may be adjusted as pre- 11o viously described to provide'the degree of in closure desired. When used with a heatable spindle the clamp may'also'serve to insulate the wo'undhair fromthe head. The perforations 24 and 25 retard the conduction of 115 heat to the central portion of the member 11; and the shield '16 if formed of suitable material, will insulate end portions of the member 11 adjacent thereto; 'Still further protection may be provided by forming the 120 j aws9and 10 of fibre orother material of lowconductivity for'heat; j
