Abstract
Abstract A combined vibratory feeder drive unit, vibratory feeder bowl, and parts separator receives springs and spring-like parts in bulk, unoriented, and tangled condition and untangles the springs and other parts and feeds them to an operator or automatic parts placing device. The parts separator is supported in a central opening in the bowl by a column arranged passing through the drive unit. Parts are fed from the separator into a pocket formed in the track of the vibratory bowl to prevent the parts from being retangled with other parts already on the track, while parts still tangled when fed from the separator will eventually be fed back into the separator until they become untangled and can be properly oriented by the track of the vibratory bowl.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
244 words
Apparatus for receiving articles such as springs and spring-like parts in bulk and in unoriented and tangled condition and untangling and orienting same, the apparatus comprising, in combination: a. a parts separator assembly arranged for receiving tangled articles and separating same: b. a hopper arranged for orienting separated parts received from the separator assembly, the separator assembly being arranged centrally of and within the hopper; and c. a vibratory feeder drive unit connected to the hopper for imparting vibrations to the hopper and feeding parts received from the separator assembly; the hopper is an annular bowl which includes an outer wall and a bottom, the latter being provided with a central opening, and further including an inner wall arranged around and spaced from the opening, the outer and inner walls extending co-directionally from the bottom, the separator assembly including a separator unit arranged in the central opening of the bottom of the bowl, and the bowl further includes a spiral track extending toward the inner wall of the bowl from the outer wall of the bowl, a portion of the track adjacent the bottom of the bowl extending from the outer wall to the inner wall and spiralling more than one revolution around the bowl and forming a pocket, and the separator unit having a discharge port disposed in communication with the pocket for decelerating parts emitted from the separator unit without the parts striking parts already in the bowl and becoming entangled again.
Claim 2
Dependent Claim

Apparatus for receiving articles such as springs and spring-like parts in bulk and in unoriented and tangled condition and untangling and orienting same, the apparatus comprising, in combination: a. a parts separator assembly arranged for receiving tangled articles and separating same: b. a hopper arranged for orienting separated parts received from the separator assembly, the separator assembly being arranged centrally of and within the hopper; and c. a vibratory feeder drive unit connected to the hopper for imparting vibrations to the hopper and feeding parts received from the separator assembly; the hopper is an annular bowl which includes an outer wall and a bottom, the latter being provided with a central opening, and further including an inner wall arranged around and spaced from the opening, the outer and inner walls extending co-directionally from the bottom, the separator assembly including a separator unit arranged in the central opening of the bottom of the bowl, and the bowl further includes a spiral track extending toward the inner wall of the bowl from the outer wall of the bowl, a portion of the track adjacent the bottom of the bowl extending from the outer wall to the inner wall and spiralling more than one revolution around the bowl and forming a pocket, and the separator unit having a discharge port disposed in communication with the pocket for decelerating parts emitted from the separator unit without the parts striking parts already in the bowl and becoming entangled again.
Claim 3
Dependent Claim
66 words
Apparatus as defined in claim 1, wherein the separator unit has an intake port spaced from the discharge port thereof, and further includes a top portion provided with diverging walls aligned with the intake port of the separator unit, and a ramp extending to the diverging walls of the top portion from a terminal end of the track spaced farthest from the bottom of the bowl.
Claim 4
Dependent Claim
44 words
Apparatus as defined in claim 2, wherein the bottom of the bowl is a spider provided with the central opening and having radially extending arms connected to the drive unit, the outer wall of the bowl being connected to the arms of the spider.
Claim 5
Dependent Claim
48 words
Apparatus as defined in claim 3, wherein the drive unit includes a base, and the separator assembly includes a support column mounted on the base and arranged extending centrally through the drive unit for supporting the separator unit in the central opening of the bottom of the bowl.
Claim 6
Dependent Claim
56 words
Apparatus as defined in claim 4, wherein the separator unit includes: a housing provided with an inlet port for feeding tangled parts into the housing; striker means arranged in the housing for imparting energy to the parts; and traction means provided in the housing for promoting a spinning action of parts energized by the striker means.
Claim 7
Dependent Claim
151 words
A structure as defined in claim 5, wherein the housing is a hollow cylinder having a cylindrical wall and a pair of opposed end walls, the striker means including a disc rotatably mounted and arranged for substantially covering an associated wall of the housing, and at least one blade mounted on the disc for rotation therewith, the disc being arranged adjacent to as well as covering one of the opposed end walls for preventing parts from being jammed between the blade and the housing, the blade extending into the housing toward the other of the opposed end walls, and the traction means including an inner surface of the cylindrical wall forming a traction surface for facilitating rotation of tangled parts one out of the other, the intake and discharge ports of the separator unit being provided in diametrically opposed portions of the cylindrical wall adjacent the other of the end walls.
Claim 8
