Having fully described my invention, what I claim as
new and desire to secure by Letters Patent is:
1. A one-sided separable fastener comprising a pair
of stringer tapes, each tape having bead means projecting
on one surface and spaced from one edge thereof, scoops
?xed to said surface of the tapes, the scoops of one stringer
4
6. A one-sided separable fastener as de?ned in claim
1, wherein the coupling member of the scoops of the one
stringer is disposed adjacent the tape of said stringer, and
the coupling member of the scoops of the opposed stringer
is spaced from the surface of said tape.
7. A one-sided separable ‘fastener as ‘de?ned in claim
6, wherein the coupling members of the ?rst mentioned
being directly opposed to the scoops of the opposed string
‘scoops form said wear shelves, over which the coupling
members of the second named scoops ride in coupling
coupling and uncoupling said stringers, said shelf having
coupling the stringers.
ers when said stringers are coupled together, the scoops 10 and uncoupling the stringers.
8. A one-sided separable fastener as de?ned in claim
of each stringer having at coupling end portions thereof
1, wherein the tapes of both stringers and the scoops at
projecting hook—sha;ped coupling members operatively en
tached thereto are ‘of the same construction, ‘and the fe
gaging sockets in the scoops of a companion stringer in
male socket portions of each of the scoops include said
coupling the stringers together, the scoops of at least
wear shelves, over which the coupling members of the
one stringer having a Wear shelf, over which the coupling
scoops of the opposed ‘stringers ride in coupling and un
members of the ‘scoops of the opposed stringer ride in
a wear surface superimposed but spaced from and parallel
to the surface of the tape to which the scoops are at‘
tached, and the longitudinal parting line of said scoops
spaced transversely of said stringer tapes from the longi‘
tudinal parting line of said tapes
2. A one-sided separable fastener as de?ned in claim
1, wherein the bead means on ‘one stringer comprises
spaced beads ‘and on the opposed stringer a pair of closely
adjacent beads.
3. A one-sided separable fastener as de?ned in claim
2, wherein the scoops of the last named stringer are of
greater length than the scoops of the ?rst named stringer.
4. A one-sided separable ifastener as de?ned in claim
1, wherein the scoops of both stringers include at one
side thereof abutting portions, and means for keying the
abutting portions one with the other when the stringers
are coupled.
5. A one-sided separable fastener as de?ned in claim
4, wherein said keying means comprises a keyway on the
9. A one-sided separable fastener as de?ned in claim
8, wherein one side of the scoops on each stringer have
projecting rounded portions, and said rounded portions
being adjacent on coupled stringers to provide means
checking stringers against forcible mismcshing.
10. A one-sided separable fastener as de?ned in claim
8, wherein the wear shelves of the scoops of both stringers
have exposed edges arranged angularly to abutting edges
of the tapes of coupled stringers.
