Abstract
Abstract Article transfer apparatus particularly for use in glassmaking, comprises a first continuously rotating device carrying a plurality of pivotally mounted article-engaging members, and a second continuously rotating device carrying a plurality of article-gripping members adapted to receive articles from said article-engaging members, wherein said first and second devices rotate in the same direction and in synchronism, the pitch circles of the article-engaging members and the article-gripping members overlap, and means associated with the first device causes each article-engaging member to pivot to effect transfer of an article therefrom to an article-gripping member.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
190 words
Apparatus for transferring articles from a first to a second station comprising a first device continuously rotating about a first vertical axis and carrying a plurality of pivotally mounted arms provided with article-engaging members for receiving vertically disposed articles from the first station, cam follower means on each said arm, and a second device continuously rotating about a second vertical axis and carrying a plurality of articlegripping members adapted to receive articles from said articleengaging members and transfer said articles to said second station, said first and second devices rotating in the same direction and in synchronism, the pitch circles of the articleengaging members and the article-gripping members which are formed by tracing the path of the central axes of the articles being carried thereby are overlapping and the path of movement of the article-engaging members being higher than that of the article-gripping members by a distance less than the vertical height of the articles and cam means associated with the first device and engageable by said cam follower means causing each arm to pivot to effect transfer of an article from its associated article-engaging member to an article-gripping member.
Claim 2
Dependent Claim
190 words
Apparatus for transferring articles from a first to a second station comprising a first device continuously rotating about a first vertical axis and carrying a plurality of pivotally mounted arms provided with article-engaging members for receiving vertically disposed articles from the first station, cam follower means on each said arm, and a second device continuously rotating about a second vertical axis and carrying a plurality of articlegripping members adapted to receive articles from said articleengaging members and transfer said articles to said second station, said first and second devices rotating in the same direction and in synchronism, the pitch circles of the articleengaging members and the article-gripping members which are formed by tracing the path of the central axes of the articles being carried thereby are overlapping and the path of movement of the article-engaging members being higher than that of the article-gripping members by a distance less than the vertical height of the articles and cam means associated with the first device and engageable by said cam follower means causing each arm to pivot to effect transfer of an article from its associated article-engaging member to an article-gripping member.
Claim 3
Dependent Claim
16 words
Apparatus as claimed in claim 1, wherein each article-engaging member comprises a vertically reciprocably forked cradle.
Claim 4
Dependent Claim
30 words
Apparatus as claimed in claim 2 wherein a pneumatic or hydraulic cylinder is associated with each article-engaging member and is actuable to cause the vertical reciprocation of its associated cradle.
Claim 5
Dependent Claim
41 words
Apparatus as claimed in claim 3 wherein the actuation of said cylinder is effected by means of a cam follower associated with the piston of a valve controlling the fluid supply to said cylinder running along a suitably shaped stationary cam.
Claim 6
Dependent Claim
31 words
Apparatus as claimed in claim 2 wherein each cradle is mounted on the outer end of an arm which is pivotally mounted in a plate attached to a continuously rotating shaft.
Claim 7
Dependent Claim
17 words
Apparatus as claimed in claim 1 wherein each article-gripping member comprises a pair of cooperating gripping jaws.
Claim 8
Dependent Claim
18 words
Apparatus as claimed in claim 6 wherein each pair of gripping jaws is spring-biased into the closed position.
Claim 9
Dependent Claim
35 words
Apparatus as claimed in claim 7 wherein the opening and closing of the gripping jaws is effected by means of a cam roller associated with each pair of jaws following a suitably shaped stationary cam.
Claim 10
Dependent Claim
20 words
Apparatus as claimed in claim 1, wherein the first and second continuously rotating devices are driven from a common drive.
Claim 11
Dependent Claim
42 words
Apparatus as claimed in claim 1, wherein a cam follower associated with each article-engaging member engages a stationary cam associated with the first device to cause each article-engaging member to pivot to effect transfer of an article therefrom to an article-gripping member.
Claim 12
Dependent Claim
38 words
Apparatus as claimed in claim 10 wherein said cam associated with the first device has a profile the major part of which is circular and which has a reentrant portion causing the pivotting movement of the article-engaging members.
Claim 13
Dependent Claim
24 words
Apparatus as claimed in claim 11 wherein said cam is formed by a groove provided in a stationary plate associated with the first device.
Claim 14
Dependent Claim
21 words
Apparatus as claimed in claim 12 wherein a roller mounted on the inner end of each arm runs in said groove.
