Abstract
Abstract The present invention relates to a welding pin dispensing magazine for holding and feeding a stack of sheet metal welding pins whereby the pins may be moved longitudinally relative to the carrier portion of the magazine, but are prevented from being shifted transversely relative thereto until the same reach a discharge station. The pins are held in shingled fashion in such manner that the edge portions of the pins define a sawtooth arrangement which facilitates serial feeding and releasing of the pins.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
162 words
As a new article of manufacture, a dispensing magazine charged with serially removable weld pins comprising, in combination, a stack of weld pins each including a head portion and a shank portion at right angles to said head portion, an open channel in said head extending from said shank to the periphery of said head, and a non-reentrant recess portion formed in said head, said pins being stacked with the under surfaces of the heads of each pin overlapping the upper surface of the next lower pin and with the shanks of adjacent pins in parallel overlapping relation and extending through the channel portions of said adjacent pins, and with said recess portions in alignment, an elongated carrier member including a guide means extending lengthwisely of said stack for supporting said stack for axial movement relative to said carrier, and retainer means extending into the aligned recess portions of said stack, for limiting transverse movement of said pins relative to said carrier.
Claim 2
Dependent Claim
162 words
As a new article of manufacture, a dispensing magazine charged with serially removable weld pins comprising, in combination, a stack of weld pins each including a head portion and a shank portion at right angles to said head portion, an open channel in said head extending from said shank to the periphery of said head, and a non-reentrant recess portion formed in said head, said pins being stacked with the under surfaces of the heads of each pin overlapping the upper surface of the next lower pin and with the shanks of adjacent pins in parallel overlapping relation and extending through the channel portions of said adjacent pins, and with said recess portions in alignment, an elongated carrier member including a guide means extending lengthwisely of said stack for supporting said stack for axial movement relative to said carrier, and retainer means extending into the aligned recess portions of said stack, for limiting transverse movement of said pins relative to said carrier.
Claim 3
Dependent Claim
40 words
The charged magazine of claim 1 wherein said retainer means is of lesser length than said guide means, the terminal end of said retainer means defining a discharge station whereat said pins may be transversely shifted clear of said magazine.
Claim 4
Dependent Claim
54 words
The magazine of claim 1 wherein said recesses of said pins are in communication with said channels, said guide means comprises at least one flange extending between each said shank and a wall defining said channel, and said retainer means comprises an elongated lip angularly offset from said flange and disposed within said recesses.
Claim 5
Dependent Claim
38 words
The magazine of claim 3 wherein said carrier member is generally U-shaped in transverse section and includes a pair of parallel flanges connected by a back portion, said shanks being disposed within said U of said carrier member.
Claim 6
Dependent Claim
45 words
The magazine of claim 4 wherein said pins include two said recesses located, respectively, at opposite sides of the junction of said shank and head, and said flanges each include a said lip forming a terminal extension thereof and lying within one of said recesses.
Claim 7
Dependent Claim
212 words
A dispensing magazine charged with serially removable weld pins comprising, in combination, a stack of integral sheet metal weld pins, each including a head portion, a shank portion bent at right angles to said head portion, said shank terminating in a sharpened tip, said shank being defined by slits extending from the periphery of the head inwardly to a junction with said head substantially centrally thereof, the space between said slits defining a channel in said head opening to the periphery thereof, at least one enlarged, non-reentrant recess portion forming an extension of and offset from one said slit, said pins of said stack being nested with the under surface of the head of each pin adjacent the upper surface of the next lower pin and with the shanks of adjacent pins in parallel overlapping relation and extending through the channels of a plurality of adjacent pins, and an elongated carrier member supporting said pins against transverse movement while affording axial movement relative to said carrier, said carrier including a track portion disposed within at least one said slit, said track portion including a retainer section having a retainer lip angularly related to said track portion and disposed within said aligned recess portions of said stacked pins to block said transverse movement.
Claim 8
Dependent Claim
212 words
A dispensing magazine charged with serially removable weld pins comprising, in combination, a stack of integral sheet metal weld pins, each including a head portion, a shank portion bent at right angles to said head portion, said shank terminating in a sharpened tip, said shank being defined by slits extending from the periphery of the head inwardly to a junction with said head substantially centrally thereof, the space between said slits defining a channel in said head opening to the periphery thereof, at least one enlarged, non-reentrant recess portion forming an extension of and offset from one said slit, said pins of said stack being nested with the under surface of the head of each pin adjacent the upper surface of the next lower pin and with the shanks of adjacent pins in parallel overlapping relation and extending through the channels of a plurality of adjacent pins, and an elongated carrier member supporting said pins against transverse movement while affording axial movement relative to said carrier, said carrier including a track portion disposed within at least one said slit, said track portion including a retainer section having a retainer lip angularly related to said track portion and disposed within said aligned recess portions of said stacked pins to block said transverse movement.
Claim 9
Dependent Claim
46 words
The apparatus of claim 6 wherein said carrier member is generally U-shaped in transverse section and includes a pair of parallel flanges defining said track portions connected by a back portion, said flanges extending into said slits, with said shanks being disposed within said U section.
Claim 10
Dependent Claim
34 words
The apparatus of claim 7 wherein said pins include two said recess portions in said heads and each said flange includes an angularly offset lip extending into a different one of said recess portions.
Claim 11
Dependent Claim
38 words
The apparatus of claim 8 wherein said lips extend less than the entire length of said flanges, the terminal ends of said lips defining a discharge station whereat said pins may be shifted transversely outwardly of said carrier.
Claim 12
Dependent Claim
162 words
As a new article of manufacture, a dispensing magazine charged with serially removable weld pins, comprising a stack of weld pins, each having a head portion and a shank portion bent at right angles to the head portion, a laterally open channel in said head portion extending from said shank portion to the periphery of said head portion, said pins being nested with the under surface of the head of each pin engaging the upper surface of the next adjacent pin, and with the shanks of adjacent pins in parallel overlapping relation and extending through the channel portions of said adjacent pins, a carrier member, linear track means on said carrier member extending into said channel and slidingly supporting said stack of weld pins, the pins of said stack having their head and shank portions inclined at acute angles relative to the longitudinal axis of said carrier member, whereby the peripheral portions of said heads of said pins are in shingled relation.
Claim 13
Dependent Claim
