Abstract
Abstract An apparatus for placing at least one washer-shaped component, e.g., washer and the like, on an elongated object, e.g., nail, screw, rivet and the like comprises: Moveable carrier having at least one receptacle aligned with the groove therein; elongated object inlet to supply elongated objects to the carrier; magnetic elements located at least partially within the groove for attracting and holding elongated objects; inlet means to supply washer-shaped components to the receptacles; assembly plane to urge the elongated object held by the magnetic element through the hole in the washer-shaped component in the receptacle; and an exit for removing and recovering the elongated object and washer-shaped component combination from the carrier. An improved method for placing washer-shaped components on elongated objects has also been discovered.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
257 words
An apparatus for placing at least one washer-shaped component on an elongated object to form an elongated object and washer-shaped component combination which comprises: moveable carrier means having at least one elongated groove therein and at least one receptical aligned with said groove for receiving a washer-shaped component; object inlet means located adjacent to said moveable carrier means to supply an elongated object to said carrier means; magnetic means located on said carrier and positioned with respect to said groove, said means exerting magnetic forces so that as said carrier means moves, said magnetic forces attract and hold said elongated object from said object inlet means at least partially within said groove; inlet means located adjacent to said moveable carrier means to supply a washer-shaped component to said receptacles of said carrier means so that the hole of said washer-shaped component is positioned in said receptacle in substantial alignment with the axis of said elongated object which is attracted to and held in said groove by said magnetic means on said carrier; assembly means located in proximity to said carrier means so that, as said carrier means moves, said assembly means comes in contact with said elongated object held by said magnetic means to urge said elongated object through the hole of said washer-shaped component in said receptacle to form said elongated object and washer-shaped component combination; and exit means located in proximity to said carrier means to remove and recover said elongated object and water-shaped component combination from said carrier means as said carrier means moves.
Claim 2
Independent Claim
257 words
An apparatus for placing at least one washer-shaped component on an elongated object to form an elongated object and washer-shaped component combination which comprises: moveable carrier means having at least one elongated groove therein and at least one receptical aligned with said groove for receiving a washer-shaped component; object inlet means located adjacent to said moveable carrier means to supply an elongated object to said carrier means; magnetic means located on said carrier and positioned with respect to said groove, said means exerting magnetic forces so that as said carrier means moves, said magnetic forces attract and hold said elongated object from said object inlet means at least partially within said groove; inlet means located adjacent to said moveable carrier means to supply a washer-shaped component to said receptacles of said carrier means so that the hole of said washer-shaped component is positioned in said receptacle in substantial alignment with the axis of said elongated object which is attracted to and held in said groove by said magnetic means on said carrier; assembly means located in proximity to said carrier means so that, as said carrier means moves, said assembly means comes in contact with said elongated object held by said magnetic means to urge said elongated object through the hole of said washer-shaped component in said receptacle to form said elongated object and washer-shaped component combination; and exit means located in proximity to said carrier means to remove and recover said elongated object and water-shaped component combination from said carrier means as said carrier means moves.
Claim 3
Dependent Claim
42 words
The apparatus of claim 1 wherein said moveable carrier means comprises a rotatable disc having at least one elongated groove located at or near the periphery of said disc and at least one receptacle aligned with said groove for receiving washer-shaped components.
Claim 4
Dependent Claim
13 words
The apparatus of claim 1 which comprises a plurality of said magnetic means.
Claim 5
Dependent Claim
13 words
The apparatus of claim 2 which comprises a plurality of said magnetic means.
Claim 6
Dependent Claim
30 words
The apparatus of claim 4 wherein said assembly means comprises an essentially stationary plane situated so that said plane slants downwardly relative to the direction of rotation of said disc.
Claim 7
Dependent Claim
121 words
The apparatus of claim 5 wherein said object inlet means comprises supply hopper means for storing elongated objects; chute means for transporting elongated objects from said supply hopper means in a single file array toward a supply means; supply means located at the termination of said chute means for supplying the next single elongated object to be picked up and held by said magnetic means to said magnetic means; and pin means located on said disc, the number of said pin means being equal to the number of said magnetic means, whereby said supply means is mechanically responsive to the movement of said pin means so that as said disc rotates, the next elongated object is supplied to said magnetic means.
Claim 8
Dependent Claim
50 words
The apparatus of claim 6 wherein said exit means comprises removal means located in proximity to said rotatable disc for removing said combination which comes into contact with said removal means from said magnetic means and a transport means from transporting said combination thus removed away from said rotatable disc.
Claim 9
Dependent Claim
28 words
The apparatus of claim 7 wherein said removal means comprises a plurality of second magnetic means which act to attract and hold said combination from said rotatable disc.
