Description
J. H. ADAMS NONSLIPPING HAIRPIN Filed Aug.- 11, 1934 INVENTOR ATTORNEYS Patented Jan. 7, 1936 UNITED STATES PATENT OFFlflE' 3 Claims.
My present invention relates to the art of hair pin making and more particularly to a non-slipping hair pin.
My present invention relates specifically to that type of hair pin which is the form, or corrugated in such a manner as, to offer considerable resistance to the removal of the hair pin after it has been inserted in the hair. This general object is accomplished by forming each shank of my hair pin so that it has outwardly extending bends and also laterally extending bends but which is further so, arranged that one side of the hair pin presents, in effect, a fiat surface to the wearers head.
With this construction I provide bends in three directions but, by virtue of the fact that one side is in effect substantially flat, it is as comfortable when used as the conventional type of hair pin.
Other and more specific objects will be apparent from the following description taken in connection with the accompanying drawing, wherein Figure 1 is a front view of a hair pin made after the teachings of my invention.
7 Figure 2 is a side elevation of the hair pin shown in Figure 1.
Figure 3 is an end view of my hair pin taken from the return bend end.
Figures 4, 5 and 6 are cross-sectional views taken along the correspondingly numbered lines of Figures 1 and 2,
Referring to the drawing, throughout which like reference characters indicate like parts, my hair pin is constructed, as is common in this practice, of resilient or spring wire having sufiicient temper to yieldably maintain its normal position and shape. It is formed with the usual top bow 8 and depending shanks or legs Ill and [-2. Each of the shanks, or legs, as It! and I2 isprovided with a plurality of crimps or corrugations after the 4 showing, particularly, of Figures land 2. Any
reasonable number of these corrugations may be employed. The outstanding characteristic of my design, however, resides in having a plurality of crimps on each leg, as H] and I2, which are disposed in the plane of the hair pin and extend laterally from the legs, as crimps l4, I5 and I6. Disposed intermediate of each of the lateral crimps are a plurality of outstanding crimps or corrugations, as l8 and 2e.
50 In order to provide that the hair pin will easily be placed in the desired position in the wearers hair and will have greater resistance when it is removed, I provide that the crimps or corrugations will normally be provided with unequal 55 angles. In the various views I have indicated the shorter leg by the reference character 22 and the longer leg by the character 24. The exact angles of these two portions of the crimp is a function of the holding power required in the pin. It naturally follows that if portion 22 formeda right angle 5 with the leg upon which it is formed it would have great holding power. This is normally not desirable, however, as its removal would be very difficult indeed. The proportion, shown in Figures l and 2, has been found to be a very satisfac- 10 tory one. Here the angles of portions 22 and 24 are such that as the hair pin is inserted or removed there is a tendency, in case of any difficulty in moving the pin, that the two legs Ill and I2 will be pressed together and thus have a ten- 15 dency to enter the hair or be removed therefrom with greater ease.
I am fully aware that many attempts have been made to utilize this principle in hair pins prior to my present invention, however, I have found that 20 if the crimps or corrugations are disposed in the plane of the pin and laterally from the medial line thereof and, also, outwardly from the plane of the pin, that the maximum security is provided. Further, that if one side of the hair pin, as illus- 25 trated in Figure 2, is arranged so that there are no projections beyond the plane of the pin, that the wearer will sufier no discomfiture from use of the pin, if the flat side is worn next to the scalp. This is of particular value especially with tight 30 fitting hats, and the like, which have a tendency to press the pin into the scalp. Under'such conditions a pin, made as illustrated, will usually be more comfortable to the wearer than the common type of corrugated pin. It has been found desiras able to form the junction between the various corrugations and the legs of my hair pin with well rounded curves. This construction, illustrated at 26, 21 and 26, overcomes to a large degree any tendency of the pin to become entangled in the 40 hair, it prevents possible injury to the user and, further, lends itself more easily to economical forming.
The foregoing description and the accompanying drawing are believed to clearly disclose a preferred embodiment of my invention but it will be understood that this disclosure is merely illustrative and that such changes in the inventionmay be made as are fairly within the scope and spirit of the following claims.
Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. A hair pin having a bow and a pair of legs, said legs having thereon a series of crimps extend- 5i ing in opposite directions from the legs and in the same plane as the pin, and a second series of crimps extending in one direction from the legs and in a plane perpendicular to said pin, whereby said pin is formed with one fiat face.
2. A hair pin having a bow and a pair of legs, said legs having thereon a series of crimps extending outwardly in opposite directions from the legs and in the same plane as the pin, and a second series of crimps extending in one direction from the legs in a plane perpendicular to said pin, whereby said pin is provided with one fiat face.
3. A hair pin having a bow and a pair of legs, said legs having thereon two series of spaced, alternating crimps formed with unequal sides, one said series of crimps extending outwardly in opposite directions from the legs and in the same plane as the pin, and the other series of crimps extending in one direction from the legs in a plane perpendicular to the vided with one fiat face.
