Abstract
Abstract Crimping apparatus for feeding and crimping electrical contacts or the like of a type having a hollow sleeve portion at one end and a reduced diameter portion at the other end. The apparatus includes a crimping mechanism which indents the sleeve portion to fix it to a wire inserted therein. A reciprocable plunger moves the contact into the crimping mechanism and is mounted within a tube having a slot therein through which a contact is dropped. A vibratory feed bowl is positioned above the plunger and supplies the contacts seriatim to an orienting mechanism which includes an arm pivotally mounted on a base plate to receive the contacts one-by-one from the bowl and transfers them to an orienting slot in the plate to drop the contacts with a predetermined orientation of the sleeve and pin portions of the contact into a feed tube for guiding the properly oriented contact to the slot in the plunger tube.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
206 words
In apparatus for feeding and crimping contacts of a type having a hollow sleeve portion at one end and a reduced diameter pin portion at the other end, crimping means arranged to crimp said sleeve portion inwardly into a rigid gripping relation to the end portion of a wire inserted therein, positioning means for receiving a contact and moving the received contact to a crimping position in said crimping means, contact supply means positioned above said positioning means and arranged to receive a supply of contacts and to feed contacts seriatim in end-to-end relation, contact orienting means arranged to receive contacts one-by-one directly from said supply means and to drop each one of the contacts with a predetermined orientation of said sleeve and pin portions, said orienting means including a base plate having an orienting slot extending therethrough, an arm pivotally mounted on the base plate and having a receptacle thereon for receiving a contact from the discharge outlet of said supply means, and means for pivotally moving said arm to cause the contact to be transferred to said orienting slot, and a feed tube having an upper end receiving said contacts dropped from said orienting means and a lower end connected to said positioning means.
Claim 2
Dependent Claim
206 words
In apparatus for feeding and crimping contacts of a type having a hollow sleeve portion at one end and a reduced diameter pin portion at the other end, crimping means arranged to crimp said sleeve portion inwardly into a rigid gripping relation to the end portion of a wire inserted therein, positioning means for receiving a contact and moving the received contact to a crimping position in said crimping means, contact supply means positioned above said positioning means and arranged to receive a supply of contacts and to feed contacts seriatim in end-to-end relation, contact orienting means arranged to receive contacts one-by-one directly from said supply means and to drop each one of the contacts with a predetermined orientation of said sleeve and pin portions, said orienting means including a base plate having an orienting slot extending therethrough, an arm pivotally mounted on the base plate and having a receptacle thereon for receiving a contact from the discharge outlet of said supply means, and means for pivotally moving said arm to cause the contact to be transferred to said orienting slot, and a feed tube having an upper end receiving said contacts dropped from said orienting means and a lower end connected to said positioning means.
Claim 3
Dependent Claim
125 words
In apparatus according to claim 1, said orienting means comprising a base plate inclined downwardly from a discharge point of said supply means and having an orienting slot spaced downwardly from said discharge point and a groove in generally parallel relation To said orienting slot, and a transfer plate disposed against the upper surface of said base plate for reciprocable movement relative thereto between first and second positions, said transfer plate having receptacle means open at the lower surface thereof for receiving a contact from said discharge point in said first position and then transferring the contact to said groove when moved to said second position and then transferring the contact to a position over said orienting slot when moved back toward said first position.
Claim 4
Dependent Claim
47 words
In apparatus according to claim 2, said groove having a lower surface inclined relative to the upper surface of said base plate to become progressively shallower to the lower end thereof, and said base plate having a channel inclined upwardly from said groove to said orienting slot.
Claim 5
Dependent Claim
73 words
In apparatus according to claim 2, said orienting slot being elongated and having a length slightly longer than the length of a contact, said orienting slot having an enlarged central portion slightly wider than the diameter of the sleeve of the contact and having a pair of opposite end portions slightly wider than the diameter of the pin of the contact and slightly narrower than the diameter of the sleeve of the contact.
Claim 6
Dependent Claim
43 words
In apparatus according to claim 1, further including means defining a chute passage disposed under the orienting slot and connecting the orienting slot to the upper end of the feed tube to guide the contact from the orienting slot to the feed tube.
Claim 7
Dependent Claim
37 words
In apparatus according to claim 1, further including a resilient annular disc disposed within said crimping means for frictionally gripping the open end portion of the sleeve of the contact to position it in the crimping position.
