Specification of Letters Patent.
Patented Jui i, 1913.
Application filed August 16, 1912. Serial .No. 715,369.
To all whom, it may concern:
Be it known that I, IsAAo FALK, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Push- Pins, of which the following is a specification.
This invention relates to an improved form of push-pin, and the object thereof is to provide a push-pin, 'or tack, suitable for use wherever such articles are desirable, as, for instance, in the adjustment and support of draperies, and the like, for the use of draftsmen, 'etc., and to 'cheapen the manufacture thereof, and at thesame time provide a thoroughly practical andsatisfactory article.
A further object is to provide a push pin of such construct-ion that all possibility of the upper'end ofthe shank of the pin being forcedthrough the head, to the discomfort of the user, is avoided. I
A further object is to provide a push pincomprising a severed length of wire bent to form a shank and a head, and to arrangethe shank so as to support the head at a locality spaced from the point where it merges into the head.
A further object is to provide .a head of convolute. formation, and to so arrange the convolutions that they will'serve to support each other against the pressure exerted by the user.
Other objects and aims of the invention, more or less specific than those referred to above, will be in part obvious and in part pointed out in the course of the following description of the elements, combinations, arrangements of parts and applications of principles, constituting the invention; and
the scope of protection contemplated will be indicated in the appended claims.
In the accompanying drawings whichare to be' taken as apart of this specification, and in which I have shown a merely preferred form of embodiment of the invention; Figure 1 is a transverse, vertical, sectional view through a pin formed in accordance with this invention, the section being taken substantially on the plane of line II of,
Fig. 2; Fig. 2 is a top plan .view'of the pin shown in Fig. 1; Fig.3 is a transverse, vertical, fragmentary, sectional view, on a re-' duced scale, illustrating a means for altering whereby said convolutions are more posithe original position and shape of the sev eral convolutions of the head before the altering process was begun; and Figs. 4, 5 and 6 illustrate modifications.
Referring to the drawings by numerals, and] particularly .to Figs. 1' and 2, the nu-' meral 1 indicates the shank of the pin, and 2, the tapered, or pointed, end thereof. The whole pin comprises preferably a singlesevered length of wire bent abruptly at the upper end of the shank, as at 3, and formed into closely wound convolutions encircling the upper bent portion 3 of the shank, so as to form the head 4. There may, of course, be made as many convolutionsas desired, though four only are illustrated. The innermost convolution 5 is preferably arranged so as to engage a relatively upper surface or shoulder, as6, produced at the upper end of;
the shank 1 by the bend 3, the engagement with said shoulder serving to positively support. the inner convolution against movement downwardly along the shank, when the the material of the convolutions, already wound, as clearly shown in Fig. 1, and, by dotted lines in Fig. 2, so that said lapping portions'fo'rm positive resistance to movement of one convolution relatively to an other when the pin is being pushed. This arrangement, provides a substantially solid central portion for the head, the relative size of which portion is obviously determined by the number of convolutions arranged in overlapping relation. In fact the whole head may be arranged in this manner, if desired. Beyond these, more convolutions, as 9, may be added, in a common plane, if desired, for enlarging the head.
Since ordinary round wire is cheapest to use for the making of these pins, it maybe desirable after they are formed, as above described, to press the heads as illustrated in Fig. 3. This operation is, however, not essential to the production of apin embodying the characteristics of this inyention. The press illustrated comprises a. bottom die l'0 having a central aperture 11 for the reception of the shank of the pin, and prefersubstantially into the cross-sectional contours illustrated in this figure, their original position, and the fact that the outer dimensions of the head are limited by portions 13 of the die 12, serving to form the several cross-sectional contours so as to provide the relatively inclined contacting surfaces 14,. which serve to prevent movement of one' convolution relatively to the other in one direction.
It will be noted that in the structure of Fig. .1 the outer edge of. the pin is removed from the transverse plane of the inner sur face of the bend 3 so that the outer annular portion of the pin could not possibly come into holding contact with an article to be held. Since this fact may be objectionable for some purposes, it' is, of course, within the province of this invention'to form the head as shown in-Fig. 4, wherein, all of the several convolutions thereof are arranged in a common plane, so that the under side of the head forms a holding surface through-,
out its extent. The inner convolution 5 in this'mOdificatiOn, preferably engages the shoulder portion 6, of the shank, as in Fig.
1, though this engagement may be elimi nated, if desired. In this modification the several convolutions are obviously capable only of supporting one another through the action of such friction as may be. present:
between the contacting surfaces. The wire -fr0m .which the pin is fashioned should, therefore, preferably be of ."a somewhat heavier quality than in the structure Fig. 1.
In Fig. 5 a pin is illustrated constructed in all respects similar to that shown in Fig. 1, but being provided with an additional convolution as 15 disposed so that its under surface lies in a plane common with, or preferably slightly below, the plane of the under surface of the bent portion 3 of the shank. This additional convolution forms a holding I face into which the pin is pushed.
In Fig. 6 there is illustrated a pin formed of a wire, which, though slightly more expensive to manufacture, produces -a pin having a substantially solid head. The
cross-sectional contour of this wire is preferably such as to provide a groove 16 extending along one side and a corresponding ridge 17 extending along its opposite side, so that when the wire is wound into convolutions, as "shown, the groove 16 of-each convolution will'engage over the juxtaposed ridge 17 of the next succeeding convolution,
'ters Patent, is:
rim upon the pin such as will engage a surand these overlapping portions, in the completed: article, will positively hold the several convolutions against movement relatively to each other in both directions longitudinally of the shank'l. The shoulder 6 performs the same function in this modification as heretofore, and, making the first or innermost convolution rigid, provides a substantial support for positively supporting the head as a whole. lVith this or similar specially shaped wire, the head of the pin. may be made substantially fiat as illustrated, which structure is desirable in many instances.
As many changes could be made in th above construct-ion without departing from the scope of this invention, it is intended that all matter contained'herein, or shown in the accompanying drawings, shall be interpreted as illustrative and not in a limiting sense, and that the language used in the, following claims is intended to cover all of the generic and specific features of the invention as defined by the claims.
