ASSGNORS TO ROYAL MB COMPANY, OF LEOMINSTER, MASSACHUSETTS, A COR- PORATION 0F TEASSACHSETTS Application filed July 8,

To all whom it may concern:

Be it known that we, FDMUKD P. PADLEY, a citizen of the United States, and CRoFToN C. HOLDEN, a subject of the King of Great Britain, residing at Leominster, in the county ot Vtorcester and State ot Massachusetts, have invented new and useful Improvements in Combs, of which the following is a specification.

This invention relates particularly to vcombs for use in confining bobbed hair, and has tor its object to provide a comb of the so-called round or curved variety, adapted not only to conform approximately to the back portion ot the human head, but also to be locked to, or lirmly engaged with the hair, by the operation of inserting` the comb teeth in the hair, so that the inserted comb is not liable to be accidentally displaced.

rthe invention is embodied in the improvements hereinafter described and claimed.

@t the accompanying drawings forming a part of this speciicatiom- Figure l is a plan view of a comb ernbodying the invention.

Figure 2 is a side view or" the same, looking from the right in Figure l.

Figure 3 is a fragmentary side view on an enlarged scale, showing the spacing of the teeth when the comb has its normal curvature.

Figure 4 is a section on line 4 4: of Figure 3.

Figure 5 is a view similar to Figure 3, showing the spacing ot the teeth when the comb is flexed to decrease its normal curvature.

Figure 6 is a plan view, and Figure 7 a side view of the comb having a deeper curvature.

The same reference characters indicate the same parts in all of the gures.

ln the drawings, l2 represents the resilient back of our improved comb, which has substantially the usual longitudinal curvature of a "round7 comb, presenting a salient outer face and a reentrant inner tace, and may be made of any suitable resilient material, such as celluloid, adapted to retain a normal curvature such as that shown by full lines in Figure l, and to be iexed to decrease said curvature as shown by dotted lines. rl`he back may have any desired ornamentation.

1922. Serial No. 573,557.

The teeth 13 ot the comb, usually integral with the back, project from the inner edge of the back as usual, and are longitudinally curved, so that they present salient outer sides and reentrant inner sides. The points of the teeth are on a curved line substantially concentric with, and having a shorter radius than, the curvature of the back.

The arrangement is such that when the back has its normal curvature, as shown by full lines in Figure l, the outer end portions of the teeth are spaced a minimum distance apart, as shown by Figure 3, and when the back is flexed to decrease its normal curvature, as shown by dotted lines, the outer end portions of the teeth are more widely spaced apart, as shown by Figure 5. This result is due to the tact that the points ot the teeth are on a curved line of shorter radius than the normal curvature of the back, so that the operation of flexing the back to decrease its curvature increases the radius ot the line of the teeth points, and causes the points to stand farther apart. ln applying` the comb to the hair, the user, grasping the ends ot the comb, rst tlexes the back to decrease its normal curvature, then inserts the teeth in the hair while the back is so ilexed, and then releases the comb, which assumes its normal curvature, causing the outer end portions ot' the teeth to approach each other, and exert binding pressure on the hair interposed between them, so that the `comb is firmly engaged with the hair, and is not liable to be accidentally displaced.

The curvature of the teeth is such that their reentrant inner sides conform approximately to the curvature of the back of the wearers head, and their opposed edges have a more effective gripping action than would be the case if the teeth were straight and inclined inward and downward from the back. ln other words, the curved inner sides are substantially parallel with the portion of the back of the head covered by the comb, so that the hair is grasped at a more uniform distance from and closer to the scalp, than would be the case if the teeth were straight and inclined.

We claim:

A comb having a longitudinally curved resilient back, presenting a salient outer face and a reentrant inner face, and longitudinally curved teeth projecting from the llO inner edge VAo"- the back, and presenting salient outer sides and reentrant inner sides, the points of the teeth being;y on a curved line of shorter radius than the curve of the back, and the arrangement being such thaty When the back is iexed to decrease its normal curvature, the spacing of the outer portions of the teeth from each other is in-` creased, and when thehack returns to its nor mal curvature, the teeth approach each other lo to grip hair which may have been interposed between the teeth While the baek'is so flexed. In testimony whereof We have afiixed our signatures.
