G. JOHNSON METHOD OF FORMING AND ATTACHING SEPARABLE FASTENER ELEMENTS Original Filed July 14, 1928 Patented Dec. 27, 1932 UNITED STATES GUSTAV JOBJTSON, OF WEST BOXBUBY, MASSACHUSETTS, ASSIGNOR TO UNITED-CABS FASTENIB CORPORATION, OF CAMBRIDGE, IMASSACEUSET'IS, A CORPORATION OF MASSACHUSETTS METlIDID OF FORMING AND ATTACHING SEPAEABLE FASTENER ELEMENTS Original application filed July 14, 1928, Serial No. 292,896, new Latent No. 1,865,393, June 28, 1932. Divided and this application filed February 2, 1929. Serial No. 337,085.
My invention aims to provide improvements in separable fastener elements and the method of forming and attaching the fastener elements to a tape or stringer.
This application is a division of my prior application, Serial No. 292,896, filed July 14, 1928 now Patent 1,865,393.
In the drawing which illustrates a preferred embodiment of my invention Figure 1 is an elevational view of portions of stringers attached to a part having an opening to be closed by the fastener elements secured to the stringers and also shows a slider for fastening and unfastening the fastener elements;
Fig. 2 is an enlarged section taken on the line 2-2 of Fig. 1 showing parts in elevation and parts in cross-section;
Fig. 3 is a skeleton view showing one method of passing a tape or stringer between two molds which form and attach the fastener elements to the tape or stringer;
line H of Fig. 8 showing the manner in which the fasteners are molded and attached to the tape or stringer;
Fig. 5 is a section taken on the line 5-5 of 4 showing how the female fastening means is formed in the fastener element; and
Fig. 6 is a skeletonized view of a pair of discs having a number of molds spaced about their peripheries for attaching a series of fastener elements to a stringer which is shown passing between the discs.
Referring to the emhodiment of my invention illustrated by the drawing, I have shown, particularly in Figure 1, two tapes or string: ers 1 and 2 of flexible material, such as cloth, leather, etc., attached to an article 3 adjacent the edges oi'an opening in the" article. The article maybe a coat, tobacco pouch, overshoe, etc. Each stringer has a number of fastener elements l secured thereto in spaced relation for engagement to close the opening in the arti'cle 3. A slider 5 of the conventional type is also shown.
My invention IS in the fastener elements l,
the method of making them and the manner of attaching them to a stringer. Therefore,- I have illustrated in a general manner a particular type of fastener element and means for making and assembling the fastener elements to a stringer.
'Heretotore, fasteners oi the general type becomes hard when pressed or vulcanized,
celluloid compositions containing substances impregnated with resin, or the like, to produce a tough and hard material.
Heretofore, fasteners oi the metal type were usually formed complete and thereafter attached to a stringer as a separate oporation. My invention simplifies all this into Fig. 4 is an enlarged section taken on the a single operation whereby the fastener elements are molded and secured to the edge of a stringer at-th-e same time, as least illustrated by Figs 3 and l.
One advantage of my invention is in the simple mold means hy which female means, in the form of a recess 5 for engagement with the ma e means i or a cooperating fastener element, may he formed at thesame time that the fastener element is formed and attachedto a stringer. Therefore, I may form fastener elements in which each has a female or socket portion and a male or stud portion, as shown in the drawing, or one'set of iastener elements may have two stud portions while the other set has two socket portions.
The mold blocks 8 and 9, shown in Figs. 3, l and 5, may be operated in any suitahle manner and the moldahle material may he led into the molds in any suitable manner. Furthermore, the mold lolochs 8 and 9 may he operated to move toward and away from each other or rotatable discs may be provided with a series of molds, as illustrated by Fig. 6.
In order to form the recess 6 at the same time the fastener elements are secured to a cess 6 elongated at one side. In fact the recess 6 extends through one side of the fastener element, as shown in Figs. 2 and 5, so that there is no wall at one side of the recess. The reason for one side of the recess being open is to allow the male projection 10 to come out of the recess after the fastener element has been formed and stringer.
The stringer is preferably provided with a beaded edge 11 (Figs. 2 and 4) so. that the material which forms the fastener element will flow in back of the bead at each side of the stringer to lock the fastener in place as the stringer is fed between the mold members 8 and 9. Thus, at predetermined spaced intervals along the beaded edge of the stringer. a'fastener member is formed and attached thereto in a very simple and efiicient manner.
While, in the particular method I have shown and described, it isnecessary to extend the recess 6 through one side of the fastener element, the fact that there is no wall at one side of the recess does not interfere with the successful operation of the fastener elements. Reference to Figs. 1 and 2 will readily disclose the fact that the fastener elements cana not be separated accidentally by side strains and stresses because the wall 12 at the other side of the recess effectively cooperates with the male portion 7 of a cooperating fastener element to prevent such separation.
I am aware that various means may be employed to secure theresult which my application is intended to cover and, therefore, I wish it to be understood that my invention is directed broadly to the idea of forming fastener elements, for the purposes illustrated and described, from any suitable plastic material which may be formed into durable fastener elements of this type. I also wish it to be understood that I have illustrated and described a simple specific form of means for carrying out the method ofv forming the fastener elements and the method of attaching them to a stringer. Therefore, reference is made to the following claims to indicate the scope of myinvention.
I claim: 7
attached to a which also comprises forming a male proj ection on one face of each of the stringers and a recess on the opposite face simultaneously with the forming and attaching of the fastener members.
In testimony whereof, I have signed my name to this specification.
GUSTAV JOHNSON.
1. The method of forming and attaching multiple operative fasteners to a stringer which comprises passing a stringer between opposed mold forms, supplying moldable material to said mold forms and applying the molded material to the edge of the stringer in the form of fasteners applied to the stringer at predetermined spaced intervals.
