Application August 12, 1933, Serial No. 684,808

12 Claims. (01. 132--50) This invention relates to improvements in hair dressin pins and more particularly to what is known in the trade, or art, bobby pins.

An object or" my invention is to provide a structure that is inexpensive to make, that is efiicient in retaining and holding the hair in place, after being curled. Also, one that does not become detached, or lost, from its place in the hair. This is an importar' feature, as some of the bobby pins, now in use, do not stay in place; thereby def ating the very purpose of maintaining the curl in the hair. My invention is designed to overcome this detect. 1 accomplish this result by forming near the end portions of the blades of the pin strucbup portions, on which an end cap; or small cylindrical member, is placed that is formed with inturned end, or lip, portions that engage the struck-up shoulder portions of the blades. This cap is formed with a shoulder, or central rib portion, on its inner or wall, which serves as a stop, when it placed on the ends of the blades and moved against the shoulders of the blades. The cap is retained in place, against accidental removal, by means of the struck-up shoulders engaging the inturned end portions of the cap. It is also prevented from tipping, or moving, on the ends of the blades by means of the central rib engaging the ends of the blades on one side of the struck-up portions of the blades and the interned ends of the cap engaging the shouldered portions of the blades on their opposite sides. The bobby pin is used, as follows:-aiter a wave, or curl, is formed in the hair, the blades of the pin are inserted in the ware and the end cap applied, as will be explained.

Referring to the draWing:-

Fig. 1 shows the parts of the pin assembled with the end cap in place on the ends of the blades.

Fig. 2 is a view similar to Fig. 1 with the end cap removed from the ends of the blades.

Fig. 3 illustrates the pin in use with hair between the blades and the end cap in place.

Fig. 4 is an enlarged View, partly in section, showing the struck-up shoulders on each of the blades and the internal stop, or rib projection,

on the inner surface of the cap, also, the inturned end portions of the cap.

Fig. 5 is an enlarged perspective view of the pin with the cap removed, clearly showing the flat blades and struck-up portions therein.

Referring now to the drawing in detail:-

The flat blades of the pin are indicated at 1 and 2 and are formed from a single piece of material that is suitably tempered. These blades are connected together with the integral curved portion 3. The blades have a normal set towards each other, so that they are in engagement, as indicated at the portion 4. The outer ends of the blades are each formed with the curved struck-up shouldered portions 5 and 6. The blade 1 is slightly longer than the blade 2, as shown at 7. This is for the purpose of permitting the pin to be readily applied on the hair. 8 indicates an end cap, or clamping member, for the blades. It also serves as a covering for the ends of the blades, as well as retaining the pin on the hair. This cap is formed with the inner annular ring, stop, or shoulder portion 9, as shown in Fig. 4. It is also formed with inturned end portions 10 and 11, as shown. When the cap 8 is applied, the ring, or internal 75 rib part 9, engagesthe ends of the blades near the two shoulders 5 and 6, at the points 5 and. 6', and operates, in a measure, to prevent moving the cap any further onto the blades; also, the contact between the inturned end portions 10 or 11 and the struck-up shouldered portions 5 and 6 engage at the points 5 and 6", preventing the cap 8 from being accidentally lost. It can be removed by pulling outwardly on the cap, which causes the ends of the blades to move lnward. The cap member is reversible, end for end, and may be readily applied, without its being necessary to observe which one of its ends is to be used. It is to be understood that I may, if desired, employ a cap with one end closed.

It will be seen that my pin may be readily applied and removed from a Wave of the hair and one that will not be lost, after being applied, due to its normal clamping effect and the cap memher 8. 95

It should be stated that the fiat, smooth, surfaces of the blades 1 and 2 provide an efficient clamping efiect for the hair, which would not be the case, if the surfaces of the blades were circular, or curved.

The pin may be made of any suitable color, as desired. The bobby pin may be easily removed, when necessary, by simply removing the end cap which is held in place by means of the inturned end portions 10 or 11, and then withdrawing the blade members 1 and 2 from the hair, as is readily understood.

The cap 8 is prevented from tipping or having a rocking movement on the ends of the blades, by reason of the bearing contact points 5 6 5 and 6. The ends of the blades will, of course, be moved toward each other, when the cap is applied.

What I claim is:

1. As an article of manufacture, a bobby pin comprising a one-piece member having two,

blade portions, each blade being formed with a struck-up shouldered portion, a cap member for engaging the struck-up shouldered portions, and the cap having a ring or stop portion therein for engaging the said shouldered portions when in place on the blades to prevent further movement of the cap on the blades, as described.

2. As an article of manufacture, a member comprising two flat blade portions having integral curved shouldered portions, a cap, annular means therein for engaging the said portions to prevent further movement of the cap on the blades, the curved shouldered portions further serving to engage the annular inner surface of the cap to prevent accidental removal of the cap.

f 3. As an article of manufacture, an open-ended cap member having an internal ring portion therein for engaging a shouldered part or the like on .a member for retaining the cap member on said part.

4. A bobby pin comprising in combination, of a member having two flat blades that normally engage each other, a cap, and co -operating means between the cap and the blades to prevent accidental removel of the cap, and, further to limit the movement of the cap on the blades. 5. A bobby pin comprising in combination, of

a member having two fiat blades that normally engage each other, a cap and co-operating means between the cap and the blades to prevent accidental removal of the cap, and, further to limit the movement of the cap on the blades, said means comprising projections on the blades and a stop part in the cap, as described.

6. A bobby pin construction comprising, a

member having resilient blade portions that are formed with shouldered portions, a cap member having inturned end portions for engaging the shouldered portions of the blades to prevent accidental removal of the cap.

'7. A bobby pin construction comprising, a member having resilient blade portions that are formed with shouldered portions, a cap member having inturned end portions for engaging the shouldered portions of the blades to prevent accidental, removal of the cap, said cap having an internal rib also engaging the shouldered portions to prevent a rocking or tipping movementof the cap, as described.

8. As an article of manufacture, a cap formed with an end having an inturned portion for engaging and retaining the cap on a member.

9. As an article of manufacture, a cap formed with an end having an inturned portion, and a centrally located internal rib or projection for engaging shouldered portions on a member and to prevent accidental removal therefrom, as described.

10. As an article of manufacture, a cap having open ends, each of its ends having an inwardly extending projection thereon and an internally located rib-like part for insertion on and removal from a shouldered member but is normally retained on said member.

11. As an articleof manufacture, a tubular member having a projection on its ends and a rib-like member on its inner surface, whereby a two point contact may be obtained when a member having a shouldered portion thereon, as described, is inserted therein.

12. As an article of manufacture, a cap memher having an internal ring portion therein and open at its opposite ends to permit either of its ends to be placed on a member having a shouldered portion for engaging the shouldered portion for retaining the cap member on said portion of the member.
