This invention relates to clamps, and while the invention maybe employed in the construction of clamps for performing any special function, it is described in the present specification as applied to the construction of a curl clamp. These clamps are employed for clamping the hair to maintain itin a formed curl.

One of the objects of the invention is to provide a clamp of simple construction, which can be readily formed of two members having a correlated construction enabling the same to be attached together in such a way that they can rock upon each other so as to open the clamp to receive the curl, and so that resilient means carried by one of the members will engage the other member in such a way as to urge the clamp toward its closed position.

Another object of the invention is to provide a curl clamp of this general type, which will present a substantially flat side which can be disposed against the side of the head when the clamp is in use for holding a curl in place. In this way ladies coiilures can be created without subjecting the wearer of the clamp to any discomfort.

Another object of the invention is to produce aclamp of this kind, composed of two members having a correlated construction and form, which will enable the two mem ers to be interlocked with each other when br ght into contact with each other, and so as to enable the members to rock upon each other; and at the same time, to afford two handles or pressure points at which pressure may be applied to open up the clamp.

Further objects of the invention will appear hereinafter.

The invention consists in the novel parts and combinations of parts to be described hereinafter, all of which contribute to produce an efficient clamp.

A preferred embodiment of the invention is described in the following specification, while the broad scope of the invention is pointed out in the appended claims.

In the drawing:

Fig. l is a plan of the clamp embodying our invention, the position of the curl being indicated in dotted lines- Fig. 2 is a view which is partially a side elevation and partially a section, the section portion being located at the handled end of the clamp.

Fig. 3 is a plan of the lower member of the clamp and showing its upper face, that is to say, it is a plan of this part as illustrated in Fig. 2, with the upper clamping member removed.

In practicing the invention, we prefer to employ two clamping members I and 2 which, in the present instance, are in the form of elongated plates which are superposed upon each other.

These members or plates, in practicing the invention, are given a correlated form enabling them to 'be'interlocked with each other to enable the plates to rock upon each other to separate the jaws 3 and 4 that are formed respectively, at adjacent ends of the plates. One of these jaws, for example, the jaw 3, has an offset portion 5 which is offset away from the opposite jaw 4 so,

that pressure of the two jaws against each other is concentrated at two lines or zones 6 and I which would correspond approximately to the diameter of the curl that is to be held bythe clamp.

The plates I and 2 are preferably formed with longitudinally disposed slots 8 and 9 respectively, so that the upper plate presents two parallel forks Ia, and the lower plate presents twoparallel forks 2a.

In order to enable the members I and 2 to engage each other in such a way as to prevent these two members from shifting longitudinally with respect to each other, we prefer to provide one or more projecting parts, for example, in the form of spurs such as the spurs I0, struck up from the material of the member 2; and the other member has means, preferably in the form of sockets II located to align with the spurs, and through which the spurs project. These sockets in the present instance, are formed in the upper plate I, as illustrated in Fig. 2, to align with these spurs. The sockets II are of greater width than the spurs measured in a direction parallel with the longitudinal axis of the clamp. This permits freedom of rocking movement of the members I and 2 upon each other. Furthermore, the openings or sockets II are preferably located at a dihedral angle I2 which is produced by bending the adjacent end portion of the clamping member I away from the lower member 2 so as to form a handle, or handle extension l3. The other member 2 is also provided with a handle extension I4 which may, if desired, be slightly bent upwardly beyond the location of the spurs III. In this way, a clearance angle I5 is formed between the two extensions I3 and I4 so as to enable the two handle extensions to be pressed toward each other between the thumb and a finger of the operator of the clamp.

In addition to this, we provide resilient means for normally maintaining the two members I and 3 other function of maintaining the jaws 3 and 4 of the plates normally in their closed position. In practice, we prefer to form the plates I and 2 of sheet material, such as spring steel, or similar materialhaving some resiliency; if desired, we may form this spring means integrally with one of the plates. In the present instance, we bend up a tongue I6 that is struck out of the material of the upper plate I to form its slot 8, that is to say, we bend this tongue around into how i'orm preferably as indicated in Fig. 2, and we provide the end of this tongue with an inwardly bent hook II which is hooked over the edge I8 that is formed at the inner end of the slot 9 of the member 2.

Furthermore, at about the location of this edge l8. we prefer to form an offset and dihedral angle I! in the material of the lower plate, so that from this point the bodies of the two plates l and 2 converge toward each other to their contact zone 1 already referred to.

If desired, the handle portion Il may be provided with an opening or eye 20 through it, which enables the clamp to be hung on a hook or nail for convenience, and which also enables a number of these clamps to be collected together on a ring, or cord.

It will be evident that the resiliency of the bow l6 will yieldingly resist pressure exerted on the handles I3 and I4 to open the jaws of the clamp, and when the handles are released, will close the clamp against the sides of the curl.

The two members I and 2 are preferably connected together to produce the clamp by seating the member I over the member 2 with the spurs Ill projecting up through the sockets II; then the jaw end of the plate I is swung down against the jaw or plate 2. As this movement is completed, the hook I! will snap under or over" the transverse edge I8, which interlocks the two plates to each other.

It should be understood, of course, that when the clamp is applied to a curl, the clamping member 2 will be disposed toward the scalp.

Many other embodiments of the invention may be resorted to without departing from the spirit of the invention.
