Abstract
Abstract A bridge type of top end stop is disclosed, which end stop is adapted as a common connection to join the upper ends of fastener stringers. The bridge top stop is constructed with a body portion bifurcated at one end to provide downwardly projecting jaw portions which define therebetween a bay for receiving the wedge of a slider. The body portion is disposed to embracingly overlie a length of coupled fastener elements, while the bifurcated jaw portions are each disposed to embracingly overlie a length of uncoupled fastener elements on each of opposed stringer tapes.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
130 words
In a slide fastener comprising a pair of stringer tapes, a row of interlocking fastener elements secured to and along one longitudinal edge of each of said stringer tapes and a slider movable along said longitudinal edge to couple and uncouple the rows of fastener elements, the improvement which comprises a bridge top stop positioned at an upper end of the fastener and adapted to prevent the slider from running off said upper end, said bridge top stop embracingly overlying a first length of fastener elements that remain coupled at said upper end and a second length of fastener elements that continue from said first length but are uncoupled, and said bridge top stop being bonded integrally with said first and second lengths of fastener elements to the stringer tapes.
Claim 2
Dependent Claim
130 words
In a slide fastener comprising a pair of stringer tapes, a row of interlocking fastener elements secured to and along one longitudinal edge of each of said stringer tapes and a slider movable along said longitudinal edge to couple and uncouple the rows of fastener elements, the improvement which comprises a bridge top stop positioned at an upper end of the fastener and adapted to prevent the slider from running off said upper end, said bridge top stop embracingly overlying a first length of fastener elements that remain coupled at said upper end and a second length of fastener elements that continue from said first length but are uncoupled, and said bridge top stop being bonded integrally with said first and second lengths of fastener elements to the stringer tapes.
Claim 3
Dependent Claim
130 words
In a slide fastener comprising a pair of stringer tapes, a row of interlocking fastener elements secured to and along one longitudinal edge of each of said stringer tapes and a slider movable along said longitudinal edge to couple and uncouple the rows of fastener elements, the improvement which comprises a bridge top stop positioned at an upper end of the fastener and adapted to prevent the slider from running off said upper end, said bridge top stop embracingly overlying a first length of fastener elements that remain coupled at said upper end and a second length of fastener elements that continue from said first length but are uncoupled, and said bridge top stop being bonded integrally with said first and second lengths of fastener elements to the stringer tapes.
Claim 4
Dependent Claim
130 words
In a slide fastener comprising a pair of stringer tapes, a row of interlocking fastener elements secured to and along one longitudinal edge of each of said stringer tapes and a slider movable along said longitudinal edge to couple and uncouple the rows of fastener elements, the improvement which comprises a bridge top stop positioned at an upper end of the fastener and adapted to prevent the slider from running off said upper end, said bridge top stop embracingly overlying a first length of fastener elements that remain coupled at said upper end and a second length of fastener elements that continue from said first length but are uncoupled, and said bridge top stop being bonded integrally with said first and second lengths of fastener elements to the stringer tapes.
Claim 5
Dependent Claim
70 words
The improvement as defined in claim 1 wherein said bridge top stop comprises a body portion disposed to embrace said first length of fastener elements, said body portion being bifurcated at one end to provide downwardly projecting jaw portions which are disposed respectively to embrace said second length of fastener elements on the stringer tapes and which define therebetween a slot for receiving the neck or wedge of the slider.
