Description

Filed April 18, 1966 INVENTOR. DOROTHY 6. HOEFEQ ATTOR/V United States Patent 3,382,547 DRESSMAKERS PIN Dorothy G. Hoefer, 1601 Walnut, Higginsville, Mo. 64037 Filed Apr. 18, 1966, Ser. No. 543,122 1 Claim. (Cl. 24-150) ABSTRACT OF THE DISCLOSURE This invention relates to a dressmakers pin wherein the pointed end and shank portion may be used to hold two pieces of fabric together for stitching with a sewing machine, wherein the pin has one end turned parallel with the shank portion to form a hook, and the hook end is nonpointed or blunt to prevent penetration of the hook into the material when in place.

This invention relates to a dressmakers pin for use in fastening pieces of fabric together prior to stitching, and more particularly to a device of that character wherein the shank of the pin has one pointed end and the remainder of the shank and other end are substantially of the same diameter or size.

Heretofore, with conventional pins having a shank por* tion, a pointed end and an enlarged head on the other end, when holding pieces of fabric together for stitching with a sewing machine, quite often the pressure foot of the machine would strike the head of the pin and thereby move the fabric causing an irregular stitch. This fabric motion also would often move the point of the needle to one side causing, in some instances, breakage of the needle on the down stroke.

The principal object of the present invention is to provide a new pin construction wherein no part of the pin is larger in diameter than the shank portion.

Another object of the present invention is to provide a pin having a shank portion with one end being pointed for insertion in the material and the other end being turned and extending parallel with the shank and spaced therefrom.

Still further objects of the present invention are to provide a device of this character wherein the end of the shank opposite the pointed end is turned to extend parallel with the shank and is also pointed.

Other objects and advantages of this invention will become apparent from the following description taken in connection with the accompanying drawings wherein are set forth by way of illustration and example certain embodiments of this invention.

FIG. 1 is a plan view showing portions of fabric material being stitched together With pins embodying this invention therein and the pressure foot of a sewing machine passing over the pins.

FIG. 2 is an enlarged cross-sectional view taken on the line 2-2, FIG. 1.

FIG. 3 is an enlarged plan view of the pin.

FIG. 4 is a view showing a modified form of pin embodying this invention wherein the turned end is pointed.

FIG. 5 is an enlarged cross-sectional view of the material with the modified pin shown extending therethrough.

FIG. 6 is an enlarged plan view of the modified pin.

Referring more in detail to the drawings:

1 designates the shank portion of a pin embodying the features of my invention having a pointed end 2 and the end 3 opposite the pointed end being turned to form a hook 4 and a leg 5.

The pin as illustrated in FIG. 1 is shown securing two pieces of material 6 and 6' together, the pins being in spaced apart parallel relation. Ordinarily the material is turned wrong side up and when the sewing is accomplished, it is reversed. As here illustrated, the pressure foot 7 of a sewing machine (not shown) is attached to a shank 8 to which is associated a needle 9.

When the edges of the material 6 and 6 are mated as illustrated in FIG. 1, the pins are normally inserted through the material in a manner whereby the hooks 4 lie flat and exposed and the pointed ends 2 are also exposed. When the machine is to be manipulated, the portion 10 of the pieces of material 6 and 6 will be fed under the pressure foot 7 and needle 9 of the machine and thread 11 will be stitched through and along the material as indicated in dotted lines at 11.

As illustrated in FIG. 1, the pressure foot 7 may be a directed over both the shank 1 and the leg 5 of the pins.

Unlike conventional pins, however, the pressure foot 7 will pass over the head end of the pin with ease. After the stitching is completed, the pins are removed and the material may then be turned right side out so that the portion 12 between the stitching and the edge 13 will be on the wrong side of the sewn together pieces of material.

In FIGS. 4, 5 and 6 I have shown a modified form of the pin which includes a shank portion 14, a pointed end 15 and the other end of the shank portion being turned as indicated at 16 and having a portion 17 pointed at 18 lying parallel with the shank 14.

When the pin is used in this form, the pieces of

material

19 and 20 are laid one on top of the other and the pins inserted therein as shown in FIGS. 4 and 5. It will be noted that the pointed portion 18 of the pin is underneath the layers of material as indicated at 21 and one portion 22 is on top of the material and a further portion 23 is underneath the material, FIGS. 4 and 5. Wit-h this form of the invention the pointed end 18 will penetrate the under layer 19 of the material to better retain the pin in place. However, due to the parallel relationship between the shank 14 and portion 17, the pin is easily removed after sewing, even if the stitching extends over the portion 17.

In stitching, this form operates the same as the form of FIGS. 1, 2 and the pressure foot 7 of the machine will easily move over either the portion 23 or the turned portion 16 or both.

It will be obvious from the foregoing that I have provided an improved dressmakers pin which will hold the facing edges of material together for stitching with a sewing machine and wherein the pressure foot of the sewing machine will not engage the pin in a manner to cause a deviation in the line of stitching.

It is to be understood that while I have illustrated and described one form of my invention, it is not to be limited to the specific form or arrangement of parts herein described and shown except insofar as such limitations are included in the claim.

What I claim and desire to secure by Letters Patent is:

1. In combination, a pin for temporarily holding two pieces of material in contact with each other while being sewed together with a machine having a foot member and a needle, said pin including a shank portion having a pointed one end for engaging through the two pieces of material, the other end of the shank portion being turned to form a hook having a leg portion spaced from the shank portion and extending parallel with the shank portion and toward said pointed end, a portion of said hook portion lying underneath said material so that said foot member will pass thereover and said needle will not be damaged by said hook portion, said hook portion of the pin and shank portion being of the same diameter and the hook end of the pin being non-pointed so that it will not penetrate the material when in use, said hook portion being of relatively short length so that the hook end will be adjacent and on the opposite side of the sewing 2,873,708 needle to that of the pointed end of the pin when in pinned 4 3,299,483 position. 1,454,550 2,934,032 References Cited 5 UNITED STATES PATENTS 377 644 367,939 8/1887 Tilden 24-161XR 2,015,149 9/1935 Krzeminski.
