Abstract
Abstract An automated, high-speed spring pin setter which directs spring pins from a continuous supply of pins through a delivery tube to a reciprocating loading magazine. Pins are fed initially to the magazine at a pin load station and are carried by a slide in the reciprocating magazine to a pin feed station where a plunger drives the spring pins from the magazine into the workpiece.

Claim 1
Independent Claim
243 words
In an automatic spring pin setter, means to provide a continuous supply of spring pins to a spring pin receiving and ejection assembly, said assembly comprising: a stationary block member having a channel portion therein: a slide member positioned in said channel portion and of a length less than the length of said channel portion thereby to permit said slide member to reciprocate within said channel, means operatively associated with said slide member to selectively move said slide member back and forth within said channel portion between a spring pin receiving station and a spring pin ejecting station spaced therefrom; said receiving station being located on the bottom wall of said channel portion and said ejecting station being located in the bottom wall of said channel portion; said slide member including a cutout portion on the side adjacent the bottom wall of said channel portion; said cutout portion being positioned in register with said means to supply spring pins when said slide member is at said receiving station thereby to receive and retain a single spring pin within said cutout portion whereby when said slide member is moved to said ejecting station, said sinGle spring pin is transferred from said receiving station to said ejecting station and will drop free of said slide member into said ejecting station; and means operatively associated with said assembly to eject said single spring pin from said ejecting station into a workpiece positioned adjacent said ejecting station.

Claim 3
Dependent Claim
33 words
A spring pin setter as defined in claim 1 wherein said ejecting station includes guide means to maintain the alignment of the spring pin being ejected while the spring pin is being ejected.
Claim 4
Dependent Claim
22 words
A spring pin setter as defined in claim 2 wherein said guide means comprises spring urged balls projecting into said ejecting station.
Claim 5
Dependent Claim
27 words
A spring pin setter as defined in claim 1 wherein said slide member includes an undercut portion on the side adjacent said means to supply spring pins.
Claim 6
Dependent Claim
23 words
A spring pin setter as defined in claim 4 wherein said undercut portion extends transverse to said cutout portion of said slide member.
Claim 7
Dependent Claim
51 words
A spring pin setter as defined in claim 1 wherein said means to provide a continuous supply of spring pins include a receiving bore in said block member in communication with said receiving station and wherein said ejecting station includes a recess formed in the bottom surface of said channel portion.
Claim 8
Dependent Claim
323 words
In an automatic spring pin setter, means to provide a continuous supply of spring pins to a spring pin receiving and ejection assembly, said assembly comprising: a stationary block member having a channel portion therein, a slide member positioned in said channel portion and of a length less than the length of said channel portion thereby to permit said slide member to reciprocate within said channel, means operatively associated with said slide member to selectively move said slide member back and forth within said channel portion between a spring pin receiving station and a spring pin ejecting station spaced therefrom; said receiving station being located on the bottom wall of said channel portion and said ejecting station being located in the bottom wall of said channel portion; said slide member including a cutout portion on the side adjacent the bottom wall of said channel portion; said cutout portion being positioned in register with said means to supply spring pins when said slide member is at said receiving station thereby to receive and retain a single spring pin within said cutout portion whereby when said slide member is moved to said ejecting station, said single spring pin is transferred from said receiving station to said ejecting station and will drop free of said slide member into said ejecting station; means operatively associated with said assembly to eject said single spring pin from said ejecting station into a workpiece positioned adjacent said ejecting station; said means to provide a continuous supply of spring pins including a receiving bore in said block member in communication with said receiving station and wherein said ejecting station includes a recess formed in the bottom surface of said channel portion; a plurality of balls projecting into said recess to maintain the alignment of said spring pin being ejected while the spring pin is being ejected; and an undercut portion on the side of said slider member adjacent said receiving bore.
