METHOD OF AND BLANK FOR MAKING SLIDERS FOR SLIDING CLASP FASTENERS Filed A g. 51, 1955 Arron Nay,
Patented Dec. 20, 1938 UNITED STATES PATENT OFFICE METHOD OF AND BLANK FOR MAKING SLID- ERS FOR SLIDING- CLASP FASTENERS Bruno Reiter, London,
England, assignor to In- 9Claims.
The present invention relates to the manufacture of sliders for sliding-clasp fasteners.
A slider for closing and opening sliding-clasp fasteners comprises a top and a bottom plate, between which is provided an intermediate member in the shape of a wedge or the like. The edges more easily and cheaply than it was possible with l5 methods known up to now.
Another object is to provide a blank for use in performing the method.
Further objects of the invention will be apparent from the description as it proceeds.
In order that the invention may be mare clearly understood, an embodiment thereof is described hereinafter, by way of example, with reference to the accompanying drawing, in which Fig. l is a top view of a slider already known,
Fig. 2 is a top view of one embodiment of a slider according to this invention,
Fig. 3 shows a metal blank from which a slider according to the present invention may be formed,
Figs. 4, 5, 6, and 7 illustrate several steps by which the slider may be formed from the said metal blank, Fig. '7 being the finished slider.
In all figures the same reference marks refer to the same parts.
Sliders already known comprise two parts a and b as shown in Fig. 1. In part a the edges of the slider are parallel to each other, whereas in part b the edges are divergent from each other and form together with the middle piece c divergent channels d and e.
It is also possible to dispense with part b without any detrimental effect on the working of the slider.
Fig. 2 shows one embodiment of this slider, in-
which part a is provided as before, whereas the broader part bof the top and bottom plates shown in Fig. 1 is no longer necessary. The wedge-shaped piece I which is necessary for closing the fastener can be connected to the top and/or bottom plates by small strips of metal Q,
avoided, whereby the manufacture can be further cheapened and simplified. The connecting strips. or plates may have any suitable form to give the slider as a whole an agreeable exterior shape. By this it ispossible to save metal and therefore to manufacture the new slider more 5 cheaply than the former sliders.
The treatment of the material from which the slider is built up will be much easier than the treatment which has been necessary up to now in making the known sliders as will be seen from. 10 the following description.
Figs. 3 to '7 show how an embodiment of the new slider may be made from apiece of sheet metal by punching and pressing it, according to the present invention. 15
Fig. 3 shows a blank I punched out from a piece of sheet metal. It possesses a middle part 2 and end parts 3 and 4, which are somewhat broader than the middle part. The part 4 may be rounded off as shown at 5. The lateral edges 20 of parts 3 and 4 are bent up as shown in Fig. 4 at 6, I, 8 and.9. At the same time the middle part 2 is rolled together as shown in Fig. 4 and a. rib Ill, also shown in Fig. 4, is pressed into the material to reinforce this part. 25 Fig. 5 shows a side view corresponding to Fig. 4. Fig. 6 shows how the blank is now bent after a pull device H is slipped into the loop formed by parts 2 and 4.
Finally the shape given in slider is achieved.
In Fig. 7 part 3 forms the lower plate, part 4 the top plate, both having edges which are par allel to each other. Both plates are connected outside the.slider by part 2 which works like 35 the wedge-shaped middle part of the former sliders. v
It will be appreciated that the amount of metal is very much reduced and the manufacture very much lighter in weight.
A further feature connected with the new method of making a slider is the following:
When a slider of the usual kind is used, it was necessary first to introduce both stringers con- 45 members at the two ends of the fastener, and 5 finally to furnish them with the slider which is not yet completely bent into its correct position, so that it is possible to introduce the stringers between the plates of the slider and then to give theplates their correct final position by pressing 56 Fig. '7 forming the 30 much simplified, the slider being at the same time 40 them together. The manufacture of sliding-clasp fasteners is thus further improved and rendered less expensive.
I claim:
1. Method of making a slider for sliding-clasp fasteners comprising the steps of forming a strip of metal comprising end portions connected by a middle portion, turning the side edges of one of the end portions upwards and those of, the other end portion downwards and turning one end portion through about 360 to bring the said upturned edges face to face with said downturned edges.
2. Method of making a slider for sliding-clasp fasteners comprising the steps of forming a strip of metal comprising end portions connected by a middle portion, turning the side edges of one of the end portions upwards and those of the other end portion downwards, rolling the edges of said middle portion towards one another, 'and turning one end portion through about 360 to bring the said upturned edges face to face with said downturned edges.
3. Method of making a slider for sliding-clasp fasteners comprising the steps of forming a strip of metal comprising end portions connected by a middle portion, turning the side edges of one of said end portions upwards and those of the other end portion downwards, turning one end portion through about 360 to bring the said upturned edges face to face with said downturned edges, and attaching a pull device to said middle portion.
4. In the manufacture of a sliding-clasp fastener the steps which comprise forming a strip of metal comprising end'portions connected by a middle portion, turning the side edges of'one of the end portions upwards and those of the other end portion downwards, turning one end portion through an angle less than 360 to bring the said upturned edges towards the said downturned edges, introducing the stringers which constitute the fastener and which are already connected together at one end and provided with stop means at the other end between said end portions of the slider, and finally pressing said end portions together.
5. In the manufacture of a sliding-clasp fastener the steps which comprise forming a strip of metal comprising end portions connected by a middle portion of smaller width, turning the side edges of one of the end portions upwards and those of the other end portion downwards, rolling the edges of said smaller middle portion towards one another, turning one end portion through an angle less than 360 to bring the said upturned edges towards said downturned edges, attaching a pull device to said middle portion, introducing the'stringers which constitute the fastener and which are already connected together at one end and provided with stop means at the other end, between said end portions of the slider, and finally pressing said end portions together.
6. Method of making a slider for sliding-clasp fasteners comprising the steps of forming a strip of metal comprising end portions connected by a middle portion, turning the side edges of one of.
the end portions upwards and those of the other end portion downwards, providing at least one of said end portions with at least one stiffening rib, and turning one end portion through about 360 to bring said upturned edges face to face with said downward edges.
7. For use in making a one-piece slider body for sliding-clasp fasteners, a one-piece blank of sheet material and consisting of end portions united by a narrower middle portion of length sufficient to permit of one of said end portions being turned through substantially 360 to bring said end portions together in parallel aligned relation.
8. For use in making a one-piece slider body for sliding-clasp fasteners, a one-piece blank of sheet material and consisting of end portions united by a narrower middle portion of length slightly greater than the combined length and height of the finished slider.
9. Method of making for sliding-clasp fasteners, a one-piece slider comprising top and bottom plates united by a wedge for separating fastener elements, which method comprises the steps of forming a sheet-metal blank having end portions united by a relatively long middle portion, turning the side edges of one of said end portions upwards and turning the side edges of the other of said end portions downwards, to form the top and bottom plates of the slider, rolling the edges of said middle portion towards each other, bending one end portion through 180 about said middle portion to form a loop and bring said side edges of said bent end portions the same Way up as the side edges of the other end portion, bending said middle portion through about and towards said other end portion, bending said middle portion at a point intermediate said end portions through 90 towards said other end portion to bring said end portions together in parallel aligned relation with the side edges of said end portions face to face and to simultaneously form the separating wedge of the slider, and attaching a pull device to said loop prior to performing the step last-mentioned.
