8 Claims.

This invention relates to new and useful improvements in a slide fastener.

More particularly, the invention proposes a new slide fastener which essentially consists of a bottom 4flexible strip having a plurality of spherical buttons along its length, a top exible strip having buttonholes for said buttons, and a slideI for buttoning and unbuttoning said buttons. v f

An important feature of the invention resides in the construction of the slide. It is characterized by a iiat c-shaped member having top and bottom at wall portions for engaging upon the edge portion'of said bottom strip and provided with certain members which will button and unbutton said buttons when the slide is moved forwards and rearwards.

More specifically, a bridge-like member is proposed to be mounted on the outer edge of the top wall portion of saidC-shaped member for engaging over the edge portion of the top strip. It is proposed that thisv bridge-like member be provided with a semi-tubular portion for holding down said top strip on said ybottom strip a'nd for forming a passage for said buttons when said strips and slide are relatively moved longitudinally of each other. It is further proposed that a hollow semi-tubular portion be disposed upon the top wall portion of said U-shaped member for said buttons to pass through when said slide is moved relative to said strips, and it is proposed that this semi-tubular portion be located to the front of said bridge-like member and have an inclined rear end for progressively lifting said top strip oil said buttons' when the slide is moved in one direction, and dropping said top strip on said buttons when the slide is moved in the other direction. 'I'his action will-accomplish the un buttoning and buttoning, as required.

Still further the invention contemplates novel Vmeans for slidably connecting the slide uponpsaid strips.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

rality of spherical buttons I3 along its length.

This bottom flexible strip is cooperative with a. top flexible strip I4- formed with buttonholes I5 for said buttons I3. There is a slide I6 for buttoning and unbuttoning said buttons I3 with said buttonholes I5. The construction of this slide forms a dominatingportion of this invention.

Y The slide I6 includes a flat C-shaped member in cross section having a top at wall portion I1, a bottom flat wall portion I8, and a bend I8 connecting one of the sides of said top and bottom `flat wall portions. This C-shaped member is adapted to be engaged upon the edge portion of the bottom strip I 2 as clearly shown in Fig. 2. A bridge-like member 20 is mounted on the outer edge of the top wall portion I'I of said C- shaped member and is for the purpose of engaging over the edge portion of said top strip I4, as clearly shown in Fig. 2. This bridgelike member 20 has a semi-tubular portion 2l extending longitudinally along its center for holding down said top strip portion I4 on said bottom strip portion' I2 when the slide is -being used. This semi-tubular portion 2| furthermore 'forms a passage for the buttons I3 when said strips I2 and I4 land said slide Il are relatively moved longitudinally of each other, as clearly indicated in Fig..3. The bridge-like member I6 is integral at one side,= namely the side 22 with the free edge of the top wall portion I1.

Means is provided for slidably connecting said bridge-like member. with the edge portion of said top strip I4. 'I'his means includes small

tubular portions

23 and 24 formed along the sides of the bridge-like member 28 and cooperative with beaded

portions

25 and 28, respectively formed along the edge portion of said strip I4. These beaded

portions

25 and 25 are formed by sewing cords 21 or similar strands within casing portions formed from the material of the top strip I4.

The vtop wall portion I1 is also formed with a hollow semi-tubular portion 28 -for the said buttons I3 to pass through when said slide I6 is moved relative to the said strips I2 and I4. This semi-tubular portion 28 is located to the front of the bridge-like member 20. This Senlitubular portion 28 is formed with an inclined rear end 28 for progressively lifting said top strip I4 olf of said buttons I3 when the slide I8 is moved in one direction, and dropping said top strip I4 on said buttons I3 when the slide I8 is moved in the other direction. The semi-tubular closed in Figs. 11 to 16, the slide fastener includes a bottom iiexible4 strip I2 having a plurality of spherical buttons I3 along its length. This bottom flexible strip is cooperative with a top flexible strip formed with buttonholes Il for said buttons I3. 'I'here is a slide I5' for buttoning and unbuttoning said buttons 'I3 and buttonholes I5. The'construction of this slide embodies -the modification of this form of the invention.

The slide I6' comprises a c-shaped member 35, see Fig. 16, having a top wall portion 38 and l portion or arm 39 formed along and projecting l forward from one side of the bridge-like member portion 28 is open at the bottom through which the buttons engage therein. The bottom strip I2 and top strip I4 are sewn together at one of their ends by the stitches 30. The slide I5 is engaged on the edge portions of the strips I2 and I4 by slightly flexing the top and bottom flat wall portion I1 and I8 thereof apart, and engaging the slide in position on the strips. The bottom strip I2 is also provided with

beaded portions

25 and 28 formed with cords 21, for decorative purposes.

The operation of the device is as follows:

When the slide I6 is moved downwards as illustrated in Fig. 1, the bridge-like member 20 will force the top strip I4 downwards onto the bottom strip I2 so that when the buttons I3 come out from the inclined end 28 of the semi-tubular portion 28 they will be forced through the button-holes I5. Thus, the slide fastener is being closed. Then the slide I6 is moved upwards, the top strip I4 will be cammed upwards by the inclined rear end 28 of the hollow semi-tubular portion 28 so that the top strip I4 is forced free `from the buttons I3.

In Figs. 8 to 10 a modified form of the invention is disclosed which distinguished from the prior form essentially in the fact that the bottom fiat wall portion I8' of the slide I6 is provided With semi-tubular portions 32 which are cooperative with the beaded

portions

25 and 26 formed along the edge of the bottom strip I2.

These beaded portions are formed with cords In the modified form of the invention dis- 38 and being opened at the side for slidably engaging the bead portion 25 formed along the edge of the strip I4. Another substantially identical arm 39' projects from and along the other side of the bridge-like member 38 and is for the purpose of holding the top strip I4 down. This portion 39' is solid and not tubular as may be seen from an inspection of Fig. 16. 'Ihe bridge-like member 38 has a semi-tubular central portion 40`forvforming a passage for said buttons I3 when said strips I2 and I4 and slide I6 are relatively moved longitudinally of each other. The front portion of the top wall portion 35 is formed with a hollow semi-tubular 'is identical to the prior forms and it is believed that its operation will be clear.

While I have illustrated and described the preferred embodiments of my invention; it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
