Abstract
Abstract An oscillating turret is provided with gripping members rotated by the rotation of the turret so that syringe barrels are transferred from a first conveyor extending substantially in the horizontal plane of the turret to a second conveyor extending in a horizontal plane above the horizontal plane of the turret and members oscillated relative to the two conveyors to transfer the syringe barrel from the first conveyor to a gripping member and transfer said syringe barrel from said gripping member to the second conveyor. The position of the syringe barrel is reversed during the oscillation of the turret.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
131 words
In apparatus to transfer and invert a syringe barrel from a first conveyor to a second conveyor spaced froM the first conveyor, a turret oscillating between the conveyors, gripping members rotatably supported by the turret and arranged to removably hold a syringe barrel, means to oscillate said turret and transfer the gripping members from a syringe barrel receiving position to a syringe barrel discharge position, means to rotate the gripping members by the oscillation of the turret, means pivotally mounted and positioned relative to each conveyor, and means to oscillate the first of said pivotal means to transfer a syringe barrel from the first conveyor to a gripping member and to oscillate the second of said pivoted means to transfer a syringe barrel from a gripping member to the second conveyor.
Claim 2
Dependent Claim
131 words
In apparatus to transfer and invert a syringe barrel from a first conveyor to a second conveyor spaced froM the first conveyor, a turret oscillating between the conveyors, gripping members rotatably supported by the turret and arranged to removably hold a syringe barrel, means to oscillate said turret and transfer the gripping members from a syringe barrel receiving position to a syringe barrel discharge position, means to rotate the gripping members by the oscillation of the turret, means pivotally mounted and positioned relative to each conveyor, and means to oscillate the first of said pivotal means to transfer a syringe barrel from the first conveyor to a gripping member and to oscillate the second of said pivoted means to transfer a syringe barrel from a gripping member to the second conveyor.
Claim 3
Dependent Claim
16 words
Apparatus as claimed in claim 1, wherein the turret is oscillated 180 degrees in opposite directions.
Claim 4
Dependent Claim
23 words
Apparatus as claimed in claim 1, wherein the means to rotate the gripping members is arranged to oscillate said gripping members 180 degrees.
Claim 5
Dependent Claim
52 words
Apparatus as claimed in claim 1, wherein each gripping member comprises an arm rotatably supported adjacent one end and the opposite end provided with a fixed lateral jaw and a resilient finger extending parallel to and spaced from the lateral jaw a distance less than the exterior diameter of the syringe barrels.
Claim 6
Dependent Claim
33 words
Apparatus as claimed in claim 1, wherein the means to oscillate the turret comprises a pinion connected to the turret and a rack meshing with the pinion, and means to reciprocate the rack.
Claim 7
Dependent Claim
53 words
Apparatus as claimed in claim 1, wherein the means to rotate the gripping members comprises a first pinion fixedly mounted in the center of the turret and a second pinion connected to each gripping member and meshing with the first pinion whereby rotation of the turret will cause rotation of the gripping members.
Claim 8
Dependent Claim
47 words
Apparatus as claimed in claim 1, wherein the pivotally mounted means comprises a post rotatably mounted adjacent to the discharge end of the first conveyor and a second post rotatably mounted adjacent to the receiving end of the second conveyor, and an arm secured to each post.
Claim 9
Dependent Claim
49 words
Apparatus as claimed in claim 7, wherein the means to oscillate the pivotal members comprises an arm pivotally mounted and connected to the first post, a cam disc reciprocating said arm, and means connecting the two posts whereby oscillation of the first post will simultaneously oscillate the second post.
Claim 10
Dependent Claim
75 words
Apparatus as claimed in claim 4, wherein the first conveyor extends substantially in the horizontal plane of the turret, and the second conveyor extends in a horizontal plane above the horizontal plane of the turret, and the means to rotate the gripping members is arranged to position the jaws and resilient fingers in horizontal alignment with the discharge end of the first conveyor and in horizontal alignment with the receiving end of the second conveyor.
Claim 11
Dependent Claim
45 words
Apparatus as claimed in claim 5, wherein the means to reciprocate the rack comprises a first arm pivotally mounted and operatively connected to the rack, a second arm pivotally mounted and connected to the first arm, and a continuously rotating cam reciprocating the second arm.
