Abstract
Abstract A continuous belt conveyor for transporting bottles to be processed includes an inclined ramp portion for elevating bottles to a moving horizontal platform portion, screw means for selectively adjusting the height of the moving horizontal platform portion without varying the length or tension of the conveyor belt, a variable pitch horizontally disposed screw guide for uniformly spacing bottles as they enter upon the moving horizontal platform, and a plurality of uniformly spaced neck gripping overhead bottle carriers mounted on a continuous overhead chain moving in synchronism with the conveyor belt, with overhead cam means adjacent to the junction between the inclined ramp portion and the horizontal platform portion of the conveyor belt for causing the overhead bottle grippers to be successively elevated over, aligned with, and then lowered onto neck locking engagement with individual bottles passing therebeneath. The overhead bottle grippers comprise a clam shell type of structure opened when elevated and closed when lowered and a surrounding rotatable cylindrical shield which holds the clam shells in locked position when lowered thereover and which also by engagement with a suitable rack produces a rotation of the bottles as they are carried thereby through a spray processing station. A synchronous drive mechanism including a feedback loop between the conveyor belt and the overhead chain conveyor maintains constant speed and physical relationship between the two continuously moving conveyor means.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
304 words
For use in an overhead conveyor system for transporting bottles or like containers from an input station through a processing station to a discharge station, a neck-gripping container carrier comprising in combination, a pair of symmetrical semi-cylindrical neck-gripping members pivotally mounted along a central upper edge to a common horizontal axis, a vertically extending shaft, yoke means symmetrically supporting said pivotal axis at the bottom end of said vertically extending shaft, means rotatably mounting the upper end of said shaft for rotation about its vertical axis, means supporting and guiding said shaft mounting means to depend vertically from an overhead movable chain, a hollow tubular member slidably mounted on said vertical shaft, a bail slidably mounted on said vertical supporting and guiding means and receiving said hollow tubular member rotatably through a central bore thereof, a cam follower mounted on said bail and said hollow tubular member may be raised and lowered by engagement with a cam, a horizontally disposed wheel concentrically mounted on the bottom end of said tubular member and rotatable therewith about the axis of said vertical shaft, said shaft passing freely through an axial bore of said wheel, a hollow cylinder depending concentrically from the bottom of said wheel and surrounding said yoke and the upper portion of said neck-gripping members, a plane bottom wall of said cylinder having a central bore to receive and encircle said neck-gripping semi-cylindrical members in their closed position, laterally extending lever arms secured to the upper ends of said semi-cylindrical gripping members and protruding beyond the diameter of said bottom wall central bore with said surrounding depending hollow cylinder, whereby said lever arms engage the inner surface of said bottom wall when said surrounding cylinder is raised by engagement of cam follower and said cam to open said semi-cylindrical members into their non-gripping position.
Claim 2
Dependent Claim
304 words
For use in an overhead conveyor system for transporting bottles or like containers from an input station through a processing station to a discharge station, a neck-gripping container carrier comprising in combination, a pair of symmetrical semi-cylindrical neck-gripping members pivotally mounted along a central upper edge to a common horizontal axis, a vertically extending shaft, yoke means symmetrically supporting said pivotal axis at the bottom end of said vertically extending shaft, means rotatably mounting the upper end of said shaft for rotation about its vertical axis, means supporting and guiding said shaft mounting means to depend vertically from an overhead movable chain, a hollow tubular member slidably mounted on said vertical shaft, a bail slidably mounted on said vertical supporting and guiding means and receiving said hollow tubular member rotatably through a central bore thereof, a cam follower mounted on said bail and said hollow tubular member may be raised and lowered by engagement with a cam, a horizontally disposed wheel concentrically mounted on the bottom end of said tubular member and rotatable therewith about the axis of said vertical shaft, said shaft passing freely through an axial bore of said wheel, a hollow cylinder depending concentrically from the bottom of said wheel and surrounding said yoke and the upper portion of said neck-gripping members, a plane bottom wall of said cylinder having a central bore to receive and encircle said neck-gripping semi-cylindrical members in their closed position, laterally extending lever arms secured to the upper ends of said semi-cylindrical gripping members and protruding beyond the diameter of said bottom wall central bore with said surrounding depending hollow cylinder, whereby said lever arms engage the inner surface of said bottom wall when said surrounding cylinder is raised by engagement of cam follower and said cam to open said semi-cylindrical members into their non-gripping position.
Claim 3
Dependent Claim
41 words
The combination of claim 1 and a toothed periphery formed on said horizontally disposed wheel engageable with a horizontal linear rack for imparting rotation to said wheel and depending cylinder about said vertical shaft as said overhead carrier moves longitudinally thereby.
Claim 4
Dependent Claim
27 words
The combination of claim 2 and means limiting relative rotation between said depending cylinder and said neck-gripping semi-cylindrical members whereby rotation is imparted to containers suspended thereby.
Claim 5
Dependent Claim
174 words
An overhead bottle carrier comprising in combination a pair of semi-cylindrical clam shell members adapted to surround and lockably engage the neck of a bottle, a common horizontal pivotal axis supporting both said members along adjacent abutting edges at the upper diameter thereof whereby said members may be swung apart into open nonengaging position, a vertical shaft rotatably supporting said common horizontal axis from an overhead conveyor chain, a hollow cylindrical shield substantially surrounding said members and movable vertically with respect thereto, a lever arm extending laterally within said shield from each of said members, a bottom on said shield engageable with said lever arms for swinging said members about said common horizontal axis into open position when said shield is raised vertically, a coaxial central bore in the bottom of said shield engageable with said members to close the same into locked neck-gripping position when said shield is lowered around said members and a cam follower linkably connected to said shield and engageable with a cam for vertically raising and lowering said shield.
Claim 6
Dependent Claim
174 words
An overhead bottle carrier comprising in combination a pair of semi-cylindrical clam shell members adapted to surround and lockably engage the neck of a bottle, a common horizontal pivotal axis supporting both said members along adjacent abutting edges at the upper diameter thereof whereby said members may be swung apart into open nonengaging position, a vertical shaft rotatably supporting said common horizontal axis from an overhead conveyor chain, a hollow cylindrical shield substantially surrounding said members and movable vertically with respect thereto, a lever arm extending laterally within said shield from each of said members, a bottom on said shield engageable with said lever arms for swinging said members about said common horizontal axis into open position when said shield is raised vertically, a coaxial central bore in the bottom of said shield engageable with said members to close the same into locked neck-gripping position when said shield is lowered around said members and a cam follower linkably connected to said shield and engageable with a cam for vertically raising and lowering said shield.
Claim 7
Dependent Claim

Claim 8
Dependent Claim
46 words
The combination of claim 4 including means for imparting rotation to said cylindrical shield about its vertical axis, and further means for coupling said shield to said closed clam shell neck-gripping members whereby a bottle held thereby may be caused to rotate about it vertical axis.
