Filed Oct. 31. 1931 INVENTOR.

Patented Oct. 4, 1932 UNITED stares P ArE NroFFIcE EDITH SIPABKE, OF BERKELEY, CALIFORNIA PIN on NEEDIiE Application filed October 31, 1931. Seria1'No. 572,304.

provide a combination pin and needle that may be easily inserted into and withdrawn from a garment, cloth or other materlal, and

at the same time, by reason of its peculiar V construction, will securely hold against accidental displacement. Y

Another purpose of the invention is to pro vide a combined pin and needle of'the char- -acter described which is characterized by special offset shanks joined by obliquely extending portions forming shoulders wherebj the special shanks and shoulders will provide for holding the pin in place, the said shanks and shoulders being so' arranged however, that the point portion and neckportion of the pin are in axial alignment andthe-pin is given a straight line efi'ect, which effect is necessary in dressmaking work, to secure accurate fittings.- 1 A further purpose of; the invention is to provide a pinof thecharacter described wherein instead of employingthe customary pin head, there is provided an eye of special construction whereby the, pin may be employed'as aneedle.

Other objects and advantages are to provide a pin or needle that will be superior in point of simplicity, inexpensiveness of-construction, positiveness of operation, and'fa cility and convenience in use andgeneralefliciency. In this specification and the annexed drawing, the invention is illustrated in the form considered to bethe best, but it is to be understood that the invention is not limited to such form, because it may be embodied in other forms; and it is also to be understood that in and by the claims following the description, it'is desired to coverthe invention in.

I whatsoever form it may be embodied. r

Referring to the drawing: i

Fig. 1 represents a side elevation of the combined pin and needle of this invention.

Fig. 2 represents a side elevation of the device of the invention taken at right angles to 'Fig. 1. t

Fig. 3 represents a modified form of the invention. i

Fig. 4' represents a top plan view of the invention shown in Figs. 1 and 2.

The pin or needle of this invention comprises a straight neck portion 1 and a straight point portion 2, the point of which is in axial alignment with the axis of the pin as a whole, passing'centrally through the neck portion 1'. Diametrically 1 opposing offset straight shank portions 3 and 4 are interposedbetween the neck and point portions. The

shank 3 is joined at one end with the point portion 2 by a slanting or oblique shoulder 5. At the other end this shank 3 isjoined to the shank portion 4 by an oblique shoulder 6 which slants in the opposite direction to and is longer than the shoulder 55. {At the other end of the shank 4 isa slanting shoulder 7 which is longer than the shoulder 6 and which joins the shank 4 with the neck portion 1. The shoulders 5,6 and 7, in increasing'in length from the point portion towards the neck portion, cause the straight shank portions3 and 4 to be offset angularly, and to extend obliquely or slant in oppositedirections from the longitudinal axis of the pin. The shanks 3 and 4 therefore slant convergently towards the shaft.

1 The arrangement of shanks and shoulders provides a pin of wedge-like form which is easily entered into or withdrawn from fabric and in this way an easy insertion or with drawal of the pin is insuredin spite of the irregular formationof the pin. After the pin has been inserted in the cloth or other material, the shanks and shoulders will securely hold'the pin in place so thatitwill not accidentally fall or work out.

At the outer end of the neck portion 1 is an eye 8 similar to the eye of a needle, whereby the pin may be used as a needle. A threading slot 9 is formed at the inner end of the 4 eye and slants towards the outer end of the much difliculty is experienced in inserting the pins in place, and again, pins of this construction do not securely hold against accidental displacement or working out. This is particularly due to the fact that the shoulders or irregular portions are offlequal size or extent. Furthermore, pinsof the type above described,rdo not produce a straight line effect and much difliculty is experienced in using them in dressmaking work where accurate fittings are required. 7

The pin of my invention may be inserted into the material or cloth much easier and will resist a casual pull or a tendency to work out of place, to a greater extent than pins such as heretofore constructed. The diametrically oifset shanks that slant convergently towards the point, together with the three shoulders increasing in length from the point, portion to the neck portion, provide for ease of insertion of the pin without detracting from the holding quality. In inserting the pin, the shorter shoulder goes through the fabric first and opens the way for the succeeding shoulders of increasing lengths, but to work its way out, the reverse holds true, for the longest shoulder which is more difficult of dislodgment must come out first. Due to. the shoulders extending or slanting in opposite directions, when one shoulder attempts to free itself, another shoulder is drawn into atighter engagement with the fabric.

I As shown in Fig. the shankand shoulder arrangement is carried out in connection with the ordinary pin, the neck portionl. being provided with a pin head 10. v 1

The fact that the pin is headless permits of feeding material in which the pins of" this invention are placed, through a sewing;ma

chine without danger of breaking the sewmg machine needle. Ordinary or -headed pins must be withdrawn before the material can beistitched in a-sewing machine. The

V absence of the head also makes it possibleto withdraw the pin from the material, from e ther end, whereas the ordinary or headed pin must bewlthdrawn head end firsts: This is an advantage in dressmaking operations as it provides for a quick insertion and removal of the pins and saves considerable time. Furthermore, the side opening slot 9 at the inner end of the eye 8, permits of a quick and easy threading of the pin when the latter is in place in a piece of cloth or garment, without necessitating withdrawing the pin.

Inasmuch as the part of the needle which is slotted to form the eye is flat or reduced in thickness, the threading slot, if located near the outer end of the eye would weaken the structure surrounding the eye so that it would be subject to ready breakage. In the present instance by having the threading slot located at the inner end of theeye, this weakening of the needle structure around the eye is eliminated and it is possible to make a comparatively large opening without danger of. cutting the thread or of catching of the edges ofthe slot when the'pinis inserted and with} drawn. The location of the slot prevents the thread from working out of the eye a? it would have a tendency to do if the slot were located near to or at the outer end of the eye. The inclination of the slot facilitates the quick and easy insertion of the thread andprevents the thread from working out of the eye. 7 e I aving thus described this invention, what I claim and desire to secure by Letters Patent 7 v 1. A pin bent at a plurality'of points equidistant from the ends of thepin and from-"one another, an oblique portion formed at each bend, at an acute angle to the'long' dinal center line of the pin, and stra' t shank portions of equal'length for etween the adjacent ends of the ,obl' e portions, and said straight shank portions being convergent and being disposed on'the alternate sides of the center line of the pin. 1 2. A pin bent ata plurality of points equidistant from the ends of the pin and from one another, an oblique portion formed at each bend, at an'acute angle to the longitudinal center line of the pin, and straight shank portions of equallength formed between the adjacent ends of the oblique portions, the said straight shank portions being convergent and being disposed on the alternate sides of the center. line of the pin, said.

oblique portions increasing in length from the point portion of the pin toward the pin head, and the said straight shank portions being longer than the oblique portions.

' A pin bent at a plurality of points equidistant from' the end of the pin and from one another, to form straight shanks at the ends-of the; pin aligned on the longitudinal center line ofthepin, and intermediate shanks of equal length disposed on alternate sides of the said center line and being convergent thereto, obl que portlons, of decreasing lengt from the head toward the point portion of the pin formed at each bend, at an acute angle to said center line and alternately in opposite directions, said convergent shank poi;- tions being formed between the adjacent ends of the respective oblique portions, said oblique portions being shorter than the said straight shanks.

In testimony whereof, I have hereunto set my hand at San Francisco, California, this 25th day of September, 1931.
