Abstract
Abstract Fastener attaching device for dispensing fastener attachment members including a body, a needle supported at the front of the body and having a bore and a slot extending into the bore, an ejector moveable into and out of the bore, an actuator link coupled to the ejector, a trigger pivotally coupled to the body and adapted to rotate the actuator link about a first pivot point to reciprocate the ejector, the actuator link being pivotally coupled to a second link which in turn is pivotally coupled to the body so that upon the drawing of the trigger towards the body the first pivot point moves towards the ejector as the actuator link pivots about the first pivot point.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
161 words
In an attaching device including a casing having a trigger pivotally coupled to said casing, a needle projecting from the casing, the needle having a central bore and a slot open at the top and opening into the bore, and a plunger slidable within the bore to push a portion of a fastener attachment member or the like through the bore and the slot of the needle, the improvement characterized by a lever pivotally coupled intermediate its ends to a link which is in turn pivotally coupled to said casing, a first end of the lever coupled to the plunger to reciprocate it and the second end slidable upon a camming surface of said trigger, means for linearly guiding said first lever end and resilient biasing means coupled to said casing and said lever for rotating said lever about the link thereby urging said second end of said lever against said camming surface of said trigger to resiliently bias said trigger.
Claim 2
Dependent Claim
161 words
In an attaching device including a casing having a trigger pivotally coupled to said casing, a needle projecting from the casing, the needle having a central bore and a slot open at the top and opening into the bore, and a plunger slidable within the bore to push a portion of a fastener attachment member or the like through the bore and the slot of the needle, the improvement characterized by a lever pivotally coupled intermediate its ends to a link which is in turn pivotally coupled to said casing, a first end of the lever coupled to the plunger to reciprocate it and the second end slidable upon a camming surface of said trigger, means for linearly guiding said first lever end and resilient biasing means coupled to said casing and said lever for rotating said lever about the link thereby urging said second end of said lever against said camming surface of said trigger to resiliently bias said trigger.
Claim 3
Dependent Claim
58 words
In an attaching device according to claim 1 characterized by guide means for linearly guiding said first end of the lever coupled to the plunger, said guide means comprising a guide projection coupled to said lever and a pair of guides supported by said body between which said guide projection slidably moves towards and away from said needle.
Claim 4
Dependent Claim
76 words
In an attaching device according to claim 2 characterized by said device including means for locating a portion of a fastener attachment member to be pushed by said plunger through the bore and slot of the needle, said means for locating supported by said casing to the rear of the needle bore and at least partially forward but out of line with said plunger when said plunger is moved its fullest extent away from said needle.
Claim 5
Dependent Claim
52 words
In an attaching device according to claim 3 characterized by said means for locating including an indexing wheel means having a plurality of teeth for feeding fastener attachment members one at a time into position to have a portion thereof pushed by said plunger through the bore and slot of said needle.
Claim 6
Dependent Claim
22 words
In an attaching device according to claim 2 in which said trigger is hollow and has interior walls for guiding said lever.
Claim 7
Dependent Claim
24 words
In an attaching device according to claim 5 in which said casing and said trigger include stop means for limiting rotation of said trigger.
Claim 8
Dependent Claim
19 words
In an attaching device according to claim 2 in which the needle has a knife at the rear thereof.
Claim 9
Dependent Claim
126 words
A fastener attachment apparatus including a body, a tubular guide member extending outwardly from the body, a bore extending lengthwise of said guide member and an elongated slot in said guide member communicating with said bore, an ejector guidably supported for reciprocating motion into said bore, guide means for guidably supporting said ejector, the improvement comprising a drive lever coupled to said ejector at one end and support means coupled to said body for pivotally supporting said lever intermediate its ends so that the point at which it is pivotally coupled to said support means floats with respect to said body and the point at which the lever is supported intermediate its end moves towards said ejector as the ejector is moved further into said bore.
Claim 10
Dependent Claim
126 words
A fastener attachment apparatus including a body, a tubular guide member extending outwardly from the body, a bore extending lengthwise of said guide member and an elongated slot in said guide member communicating with said bore, an ejector guidably supported for reciprocating motion into said bore, guide means for guidably supporting said ejector, the improvement comprising a drive lever coupled to said ejector at one end and support means coupled to said body for pivotally supporting said lever intermediate its ends so that the point at which it is pivotally coupled to said support means floats with respect to said body and the point at which the lever is supported intermediate its end moves towards said ejector as the ejector is moved further into said bore.
Claim 11
Dependent Claim
27 words
Apparatus according to claim 8 in which a rotatable trigger is pivotally coupled to said body and includes a surface for engaging said lever to rotate it.
Claim 12
Dependent Claim
21 words
Apparatus according to claim 8 in which resilient biasing means is provided to urge said lever against said rotatable trigger surface.
Claim 13
Dependent Claim
24 words
Apparatus aCcording to claim 10 in which said lever is pivotally supported by a link which is in turn pivotally coupled to said body.
Claim 14
Dependent Claim
34 words
Apparatus according to claim 11 including means for positioning a portion of a fastener attachment member one at a time at one end of the bore for pushing through said bore by said ejector.
Claim 15
Dependent Claim
22 words
Apparatus according to claim 11 in which means is provided for separating fastener attachment members from coupling members connected to a carrier.
Claim 16
Dependent Claim
72 words
In a fastener attachment dispensing apparatus, an ejector guidably supported for reciprocating motion, guide means for supporting the ejector, the improvement comprising a drive lever coupled to said ejector and means for pivotally supporting said lever intermediate its ends so that the point at which it is pivotally coupled to said support means floats with respect to said body and moves towards said ejector as the ejector is moved in one direction.
Claim 17
Dependent Claim
72 words
In a fastener attachment dispensing apparatus, an ejector guidably supported for reciprocating motion, guide means for supporting the ejector, the improvement comprising a drive lever coupled to said ejector and means for pivotally supporting said lever intermediate its ends so that the point at which it is pivotally coupled to said support means floats with respect to said body and moves towards said ejector as the ejector is moved in one direction.
Claim 18
Dependent Claim
40 words
In an apparatus according to claim 14 in which a pivotally coupled cam is provided which has a surface for rotating one end of that lever, said pivotally coupled cam is coupled to said means for pivotally supporting said lever.
