PERMANENT WAVE SPINDLE Original Filed Nov. 15, 1934 Mary K A M/edge INVENTOR Patented Apr. 22, 1941 Refiled for abandoned application Serial No. 752,864, November 13, 1934. This application July 30, 1940, Serial No. 348,495

7 Claims.

This is an application growing out of my former case, Serial Number 752,864, allowed December 16, 1936, Permanent wave spindle, in which the seven claims given herein were allowed.

The invention relates to permanent wave spin dles of the type used in connection with hair waving machines, and has for its object to provide a spindle comprising axially disposed sections around which hair to be waved is wound, and means whereby the convolutions of said hair may be tightened on the spindle by independent rotation of the spindle section for insuring a tightening operation throughout the length of the hair wrapped around the spindle.

A further object is to provide the permanent wave spindle with means whereby hair wrapped around the same may be tightened from a central point on the spindle extending in both directions from the center and from the ends of the spindle, thereby insuring a positive tightening of the hair convolutions on the spindle and substantially uniformly tensioned throughout its length.

A further object is to provide a friction clutch connection between the spindle sections whereby they will maintain their position against retrograde movement when either section is rotated to a tightening position. I

A further object is to provide a longitudinally movable shaft extending through the spindle and terminating at its outer end in a hair end holding member having interengagement with the outer spindle section, and a spring actuated handle member carried by the other end of the shaft and normally forced rearwardly with the shaft by its spring for maintaining the interengagement between the hair holding member on the outer end of the shaft and the outer spindle section.

A further object is to provide a permanent wave spindle formed from axially connected sections rotatable independently of each other whereby hair wrapped around the spindle as a whole may be tightened from inwardly towards its ends for insuring a uniform tightening of the hair convolutions around the spindle.

With the above and other objects in View the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawing:

Figure 1 is a vertical longitudinal sectional view through the spindle.

Figure 2 is a perspective view of the spindle.

Figure 3 is a perspective view of the spindle showing hair loosely wound around the same. t

Figure 4 is a perspective view of the outer end of the spindle showing the hair end holding member disengaged.

Figure 5 is a perspectiveview of the spindle showing the initial position of the parts for the hair tightening operation.

Figure 6 is a perspective view of the device showing an intermediate tightening position.

Figure 7 is a perspective view of the device showing the final tightening operation.

Referring to the drawing, the numeral i designates the inner spindle section and 2 the outer section, which are in axial relation with their adjacent ends in abutting engagement at 3. The spindle sections l and 2 are held together by means of a shaft l which extends longitudinally therethrough and has its outer end connected by means of a left hand thread at 5 in the hair end holding member 6. The shaft 4 is axially movable within the spindle sections I and 2; the purpose of which will presently appear. The inner end of the shaft 4 extends through a handle member I which is slidably and rotatably mounted at 8 on the inner end of the inner section I and is anchored to said handle member by means of a head 9 carried by the shaft. The handle member I is normally forced inwardly by means of an expansion spring it within the chamber H of the handle and engages the adjacent end of the section I, hence it will be seen that the hair end holding member 6 is normally forced inwardly for maintaining the rib l2 which is radially disposed on the outer end of the spindle section 2 in the recess l3 of the member 6 for locking these parts together for simultaneous rotation, the purpose of which will presently appear. The disengaged position of the hair end holding member 6 and handle member I is shown in dotted lines in Figure 1.

The adjacent engaging ends of the spindle sections l and 2 are provided with registering chambers I l, in which is disposed an expansion coiled spring l5 which acts as a friction clutch for holding the spindle sections l and 2 against retrograde rotation after they have been independently or collectively rotated to hair tightening position. Spring I0 is stronger than the expansion spring [5 forming the friction clutch means so that the spring [5 will not overcome the spring 10, and the parts will be maintained normally in their relative position as shown in Figure 1.

In operation the hair is tied at It with a cord H, which cord is placed through the slot la in the member 6 and then the hair is wound loosely around the spindle as a whole, said hair being designated by the numeral I9, the inner convolutions of the hair l9 around the spindle are beneath the tightening finger 28 pivotally connected at 2| to the knurled finger engaging portion 22 carried by the inner spindle member I. After the hair has been loosely wound around the spindle, the operator grasps the inner spindle section I between the fingers 23 of the left hand and with the right hand rotates the handle member 1 in the direction of the arrow 11, Figure 5. This action, through the slidable and rotatable shaft 4 carried by the handle member I, and the hair holding member 6, will cause the outer section 2 of the spindle to rotate in the direction of the arrow b, Figure 5, through the medium of the interengagement of the member with the outer spindle section 2 as there is a rib and recess connection l2 and I3 between these parts. It will be noted that as the outer section 2 rotates in the direction of the arrow 1) there will be a tightening of the inner convolutions of the hair wound around the spindle section I as the inner spindle section I is held against rotation between the fingers 23. After this operation and at the end thereof it is desirable to tighten the other convolutions of the hair.

Following the above operation and to tighten the other convolutions, and particularly the outer convolutions, the operator pushes the handle member 1 outwardly as shown in Figure 6 while still holding the inner section I between the fingers 23 of the left hand as shown in Figure 5. This action moves the slidable and rotatable shaft 4 axially outwardly so that the rib and recess connections I2 and i3 are disengaged, thereby disengaging the member 6 from the outer section 2 of the spindle, and then the operator rotates the handle 7 and the shaft 4 carried thereby in the direction of the arrow 0, Figure 6, and this action will tighten the outer convolutions of the hair around the outer spindle section 2. During this operation it will be noted that the central convolutions of the hair will assist the friction clutch spring I5 in holding the spindle sections l and 2 in abutting frictional clutch engagement centrally against the action of the expansion spring H3, and it will also be noted by having left hand threads at 5 the shaft 4 will not unscrew from the member 6. At the end of the tightening operation on the outer convolutions of the hair as shown in Figure 6, the operator releases the handle member I, thereby allowing interengagement between the spindle section 2 and the member 6, and then shifts the fingers 23 of the left hand to a position where they grip the outer spindle section 2 as shown in Figure '7. It will be noted that the friction clutch spring I5 is sufficiently strong to prevent retrograde movement of the sections in relation to each other no matter which section is gripped by the fingers, but allowing manual rotation against the frictional clutch engagement between the sections at 3. After the fingers assume the position shown in Figure '7, the operator grips the knurled portion 22 which carries the gripping finger 2i and rotates the same in the direction of the arrow d, which imparts a tightening operation on the end convolutions of the coil of hair adjacent the handle member 1, therefore it will be seen that the coil of hair around the spindle has been tightened throughout its length.

From the foregoing it will be seen that a hair Waving spindle is provided which is simple in construction, the parts reduced to a minimum and one wherein the convolutions of the hair around the spindle will be uniformly tightened throughout the length of the coil, thereby obviating loose inner coils as is now the difficulty with many spindles wherein the tensioning strain is applied to the end convolutions of the coil.

What I claim is:

1. A hair waving spindle comprising axially aligned independently rotatable sections around which a continuous coil of hair is wound, means between said sections and cooperating with said sections for holding the same against rotation after they have been selectively and independently rotated for tightening the coilof hair in a direction from inwardly towards its ends and means carried by the spindle for tightening the end convclutions of the coil of hair around the spindle.

A hair waving spindle comprising independently rotatable sections around which a coil of hair extends, a shaft extending through the sections and on which the sections are rotatably mounted, a handle carried by the shaft, a friction clutch connection between said sections, means carried by said sections for holding the end convolutions of the hair, said friction clutch connection in combination with the end convolution holding means forming means whereby said spindle sections may be independently rotated for tightening the hair coil centrally thereof and for preventing retrograde rotation of the sections after a hair tightening operation.

3. A device as set forth in claim Zincluding means carried by the spindle adjacent its ends for imparting tightening operations on the end convolutions of the hair coil.

4. A hair waving spindle comprising rotatable axially disposed sections around which a coil of hair is received, a friction clutch connection be-- tween the sections and forming means whereby said sections are held against retrograde rotation when moved in relation to each other, a shaft slidaibly and rotatably mounted in said sections, the outer end of said shaft terminating in means for holding an end convolution of the hair coil, means carried by one of the sections for holding the other end convolution of the hair coil, interengaging means between said shaft carried holding means and the adjacent end of the adjacent spindle section, a handle member carried by the other end of said shaft, spring means cooperating with said handle member and spindle sections for normally maintaining the hair holding means carried by the outer end of the shaft in interengagement with the adjacent outer end of the outer spindle section.
