Total Claims: 7
Claim 1
Independent Claim
289 words
Article conveying means comprising: first, fixed, article supporting means; first support means; second article supporting means fixedly mounted on said first support means; second support means; first mounting means for mounting said first support means, and said second article supporting means mounted thereon, on said second support means for reciprocating movement in a first direction relative to said first article supporting means; third support means; second mounting means for mounting said second support means, and said first support means and second article supporting means mounted thereon, on said third support means for reciprocating movement in a second direction, perpendicular to the first direction, relative to said first article supporting means; first moving means for reciprocating said firSt support means in said first direction; second moving means for reciprocating said second support means in said second direction perpendicular to said first direction; and control means for operating said first and second moving means in a predetermined sequence to repetitively move said second article supporting means through a closed path of travel relative to said first article supporting means; wherein said second moving means includes cam means mounted on said third support means, said cam means cooperating with said second support means, and actuating means for reciprocating said cam means in said first direction to move said second support means in said second direction; and wherein the first moving means and the actuating means comprise first and second cam members, the cam members fixed to a rotatable shaft supported by the third support means, a motor drivingly connected to the shaft by a brake and clutch mechanism, the control means connected to the brake and clutch mechanism to stop the rotation of the shaft by the motor at different angular positions.
Claim 2
Dependent Claim
289 words
Article conveying means comprising: first, fixed, article supporting means; first support means; second article supporting means fixedly mounted on said first support means; second support means; first mounting means for mounting said first support means, and said second article supporting means mounted thereon, on said second support means for reciprocating movement in a first direction relative to said first article supporting means; third support means; second mounting means for mounting said second support means, and said first support means and second article supporting means mounted thereon, on said third support means for reciprocating movement in a second direction, perpendicular to the first direction, relative to said first article supporting means; first moving means for reciprocating said firSt support means in said first direction; second moving means for reciprocating said second support means in said second direction perpendicular to said first direction; and control means for operating said first and second moving means in a predetermined sequence to repetitively move said second article supporting means through a closed path of travel relative to said first article supporting means; wherein said second moving means includes cam means mounted on said third support means, said cam means cooperating with said second support means, and actuating means for reciprocating said cam means in said first direction to move said second support means in said second direction; and wherein the first moving means and the actuating means comprise first and second cam members, the cam members fixed to a rotatable shaft supported by the third support means, a motor drivingly connected to the shaft by a brake and clutch mechanism, the control means connected to the brake and clutch mechanism to stop the rotation of the shaft by the motor at different angular positions.
Claim 3
Dependent Claim
42 words
Article conveying means as claimed in claim 1, wherein said control means includes adjustable sensors mounted in the path of movement of an actuating member carried by the second article supporting means to initiate operation of said first and second moving means.
Claim 4
Dependent Claim
42 words
Article conveying means as claimed in claim 2, wherein the first moving means and the actuating means comprise two hydraulic or pneumatic cylinders, the first cylinder mounted on the first support means and the second cylinder mounted on the third support means.
Claim 5
Dependent Claim
39 words
Article conveying means as claimed in claim 2, wherein the control means includes a manually operated on-off switch associated with each sensor to permit the second carrying means to be stopped at selected positions in its path of movement.
Claim 6
Dependent Claim
136 words
Article conveying means as claimed in claim 1, wherein the first article supporting means has a first surface with equally spaced apart article receiving means and the second article supporting means has a second surface with equally spaced apart article receiving means, the spacing of the article receiving means on the second surface being substantially the same as the spacing of the article receiving means on the first surface, said first moving means moving the second article supporting means in the first direction to have each of the article receiving means on the second surface move back and forth between two adjacent article receiving means on the first surface, and said second moving means moving said second article supporting means in the second direction to have the second surface move above and below said first surface.
Claim 7
Dependent Claim
61 words
Article conveying means as claimed in claim 1, wherein said first and second article supporting means each comprise a pair of spaced apart vertical plate members, one pair of spaced apart plate members located between the other pair of spaced apart plate members and equally spaced apart article retaining means on the upper free edges of both pairs of plate members.
