Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
171 words
A machine for severing snap fastening elements from a pair of spaced strips and attaching the snap fastener elements to a material comprising: guide spring means adapted to support one of said fastener elements, anvil means adapted to support another of said fastener elements in spaced relation to the said one fastener element, ram means oppositely disposed to said anvil means for movement thereagainst, cutting means adapted to sever each fastener element from its strip, said ram means including a portion for moving said cutting means, advancing means adapted to move each strip into position for severing by said cutting means and to advance the severed fastener elements to said ram means and said anvil means, levEr means connected to said advancing means for movement thereof, actuator means connected to said lever means to effect movement of said advancing means, and means defining an operative connection between said actuator means and said ram means whereby movement of said ram means and said advancing means are effected by the same actuator means.
Claim 2
Dependent Claim
171 words
A machine for severing snap fastening elements from a pair of spaced strips and attaching the snap fastener elements to a material comprising: guide spring means adapted to support one of said fastener elements, anvil means adapted to support another of said fastener elements in spaced relation to the said one fastener element, ram means oppositely disposed to said anvil means for movement thereagainst, cutting means adapted to sever each fastener element from its strip, said ram means including a portion for moving said cutting means, advancing means adapted to move each strip into position for severing by said cutting means and to advance the severed fastener elements to said ram means and said anvil means, levEr means connected to said advancing means for movement thereof, actuator means connected to said lever means to effect movement of said advancing means, and means defining an operative connection between said actuator means and said ram means whereby movement of said ram means and said advancing means are effected by the same actuator means.
Claim 3
Dependent Claim
103 words
A snap fastener attaching machine comprising: clamping means adapted to clamp a pair of fastener elements to a material, cutting means for severing the fastener elements from strips, feeding means adapted to move the fastener elements into positions for operation by said cutting means and said clamping means, said clamping means including a portion for operating said cutting means, linkage means connected to said feeding means for moving the same, and single actuator means operatively connected to both of said linkage means and said clamping means whereby feeding, cutting and clamping operations are performed in response to actuation of said single actuator means.
Claim 4
Dependent Claim
103 words
A snap fastener attaching machine comprising: clamping means adapted to clamp a pair of fastener elements to a material, cutting means for severing the fastener elements from strips, feeding means adapted to move the fastener elements into positions for operation by said cutting means and said clamping means, said clamping means including a portion for operating said cutting means, linkage means connected to said feeding means for moving the same, and single actuator means operatively connected to both of said linkage means and said clamping means whereby feeding, cutting and clamping operations are performed in response to actuation of said single actuator means.
Claim 5
Dependent Claim
43 words
