Abstract
Abstract A case loader, particularly for glassware, including a gripper assembly comprising a plurality of parallel arms each including an expansible diaphragm distendable toward a similar diaphragm on an adjacent arm, and a motor for moving the gripper assembly between a ware receiving station and a ware delivering station either by rectilinear motion or by arcuate motion.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
112 words
In a machine of the class described, a frame, a subframe mounted on said frame for reciprocation relative thereto, a transverse shaft journalled on said subframe for selective reciprocation therewith or oscillation relative thereto, gripper means fixed to said shaft, a pinion fixed to said shaft, a fluid motor comprising a cylinder element and a piston element, one of said elements being fixed relative to said frame and the other of said elements being reciprocable relative to said one element and carrying a rack meshing with said pinion, means for selectively restraining said subframe against reciprocation, and means for selectively restraining said gripper means against oscillation about the axis of said shaft.
Claim 2
Dependent Claim
112 words
In a machine of the class described, a frame, a subframe mounted on said frame for reciprocation relative thereto, a transverse shaft journalled on said subframe for selective reciprocation therewith or oscillation relative thereto, gripper means fixed to said shaft, a pinion fixed to said shaft, a fluid motor comprising a cylinder element and a piston element, one of said elements being fixed relative to said frame and the other of said elements being reciprocable relative to said one element and carrying a rack meshing with said pinion, means for selectively restraining said subframe against reciprocation, and means for selectively restraining said gripper means against oscillation about the axis of said shaft.
Claim 3
Dependent Claim
86 words
In a loading machine, gripper means for receiving, at a receiving station, a plurality of like articles, means for causing said gripper means to grip said articles in a common attitude, a delivery station, means for mounting said gripper means for selective reciprocatory movement or oscillatory movement through an arc of 180* between said stations, and means for shifting said gripper means, said gripper means being relaxed at said delivery station to deposit said articles either in said common attitude or in a common inverted attitude.
Claim 4
Dependent Claim
86 words
In a loading machine, gripper means for receiving, at a receiving station, a plurality of like articles, means for causing said gripper means to grip said articles in a common attitude, a delivery station, means for mounting said gripper means for selective reciprocatory movement or oscillatory movement through an arc of 180* between said stations, and means for shifting said gripper means, said gripper means being relaxed at said delivery station to deposit said articles either in said common attitude or in a common inverted attitude.
Claim 5
Dependent Claim
45 words
The machine of claim 2 in which said gripper means comprises a plurality of equally-spaced arms, each arm having at least one laterally-expandable surface mating with an expandable surface on an adjacent arm, and means for expanding said mating surfaces to grip articles located therebetween.
Claim 6
Dependent Claim
35 words
The machine of claim 3 including means for delivering articles to said gripper means in ranks and files and in which such arrangement of articles is maintained by said gripper means through the depositing step.
Claim 7
Dependent Claim
106 words
The machine of claim 2 in which the means for shifting said gripper means comprises a frame, a subframe mounted on said frame for reciprocation between registry with said receiving station and registry with said delivery station, a shaft carried by said subframe and extending transversely of the path of said subframe, said gripper means being carried by said shaft, a rotor fixed to said shaft, a fluid motor including a reciprocable element, means operatively connecting said reciprocable element with said rotor, means manipulable to restrain said subframe against reciprocating movement with said reciprocable element, and other means manipulable to restrain said rotor against turning movement.
Claim 8
Dependent Claim
40 words
The machine of claim 1 in which the gripper means comprises a plurality of substantially parallel, substantially equally laterally spaced supports, that side of each support which faces another support including an inflatable diaphragm, and means for inflating said diaphragms.
