Abstract
Abstract A pusher is disclosed for transferring plural glass containers onto a conveyor. The pusher includes a finger for each glass container. Each finger is separately retractable after its container has been transferred onto a conveyor so as to prevent a collision between the second container and the finger for the first container.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
106 words
A pusher for transferring plural containers onto a conveyor comprising a plurality of motors on a common support for movement therewith, means for oscillating said support through an arc, a discrete rod associated with each motor, a discrete finger attached to a free end of each rod, each motor being adapted to reciprocate its rod between extended and retracted positions with respect to said body, and means for causing each rod to be sequentially and independently moved by its motor to its retracted position after each rod has traversed a sufficient portion of the arc so that a container pushed thereby has transferred onto a conveyor.
Claim 2
Dependent Claim
106 words
A pusher for transferring plural containers onto a conveyor comprising a plurality of motors on a common support for movement therewith, means for oscillating said support through an arc, a discrete rod associated with each motor, a discrete finger attached to a free end of each rod, each motor being adapted to reciprocate its rod between extended and retracted positions with respect to said body, and means for causing each rod to be sequentially and independently moved by its motor to its retracted position after each rod has traversed a sufficient portion of the arc so that a container pushed thereby has transferred onto a conveyor.
Claim 3
Dependent Claim
31 words
A pusher in accordance with claim 1 including a discrete guide member coupled to each finger and guided by said common support, each guide member being parallel to its associated rod.
Claim 4
Dependent Claim
30 words
A pusher in accordance with claim 1 including an air manifold having a discrete nozzle associated with each finger for directing air at containers to be pushed by the fingers.
Claim 5
Dependent Claim
25 words
A pusher in accordance with claim 1 where the finger pushing surfaces are each disposed at a different angle with respect to their associated rods.
Claim 6
Dependent Claim
59 words
A pusher in accordance with claim 1 wherein said last mentioned means retracts one of said fingers after it has moved through an arc of about 50° and then retracts a second finger after it has moved through an arc of about 75° and then retracts a third finger after it has moved through an arc of about 105°.
Claim 7
Dependent Claim
37 words
A pusher in accordance with claim 1 wherein each motor is a pneumatic motor having a piston, each piston being connected to one of said rods, each rod being guided directly by a portion of said body.
Claim 8
Dependent Claim
21 words
A pusher in accordance with claim 6 wherein each rod is hollow adjacent the end thereof connected to its associated piston.
Claim 9
Dependent Claim
150 words
A pusher for transferring plural containers onto a conveyor comprising a plurality of motors on a common support for movement therewith, means for oscillating said support through an arc, a discrete rod associated with each motor, each motor being a pneumatic motor having a piston, each piston being connected to one of said rods, each rod being guided directly by a portion of said body, a discrete finger attached to a free end of each rod, the finger pushing surfaces being disposed at a different angle with respect to their associated rods, each motor being adapted to reciprocate its rod between extended and retracted positions with respect to said body, and means for causing each rod to be sequentially and independently moved by its motor to its retracted position after each rod has traversed a predetermined portion of the arc wherein a container pushed thereby has transferred onto a conveyor.
Claim 10
Dependent Claim
150 words
A pusher for transferring plural containers onto a conveyor comprising a plurality of motors on a common support for movement therewith, means for oscillating said support through an arc, a discrete rod associated with each motor, each motor being a pneumatic motor having a piston, each piston being connected to one of said rods, each rod being guided directly by a portion of said body, a discrete finger attached to a free end of each rod, the finger pushing surfaces being disposed at a different angle with respect to their associated rods, each motor being adapted to reciprocate its rod between extended and retracted positions with respect to said body, and means for causing each rod to be sequentially and independently moved by its motor to its retracted position after each rod has traversed a predetermined portion of the arc wherein a container pushed thereby has transferred onto a conveyor.
Claim 11
Dependent Claim
39 words
A pusher in accordance with claim 8 including an air manifold having a discrete nozzle associated with each finger for directing air at containers to be pushed by the fingers and while the containers are on a dead plate.
Claim 12
Dependent Claim
59 words
A pusher in accordance with claim 8 wherein said last mentioned means retracts one of said fingers after it has moved through an arc of about 50° and then retracts a second finger after it has moved through an arc of about 75° and then retracts a third finger after it has moved through an arc of about 105°.
