Abstract
Abstract An apparatus is disclosed for processing products aligned on a tape. In the present embodiment, the products are shown to be heat recoverable sleeves which are conveyed to a control station for insertion of a terminal. The work is then released from the control station and allowed to pass across a heater which recovers the sleeve about the terminal. To accomplish the above, a drive having a friction coupling and a positive coupling are employed to convey the work through the apparatus. A conditioned atmosphere process apparatus is employed for the heating of the sleeves and a controlled product feed apparatus controls the feeding of the work to the control station.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
123 words
A drive for a semi-automatic processing mechanism, comprising: a base; a shaft rotatably mounted on said base; means for forcibly rotating said shaft; a first wheel fixed to said shaft, said first wheel having a friction drive surface about the total periphery thereof; a second wheel fixed to said shaft, said second wheel having a positive drive surface about the total periphery thereof; and a work carrier coaxially arranged relative to said shaft, said work carrier including a friction follower extending to said first wheel and constantly containing said friction drive surface of said first wheel and a locking member extending for selective positive engagement with said second wheel at any engagement point on said second wheel defined by said positive drive surface.
Claim 2
Dependent Claim
123 words
A drive for a semi-automatic processing mechanism, comprising: a base; a shaft rotatably mounted on said base; means for forcibly rotating said shaft; a first wheel fixed to said shaft, said first wheel having a friction drive surface about the total periphery thereof; a second wheel fixed to said shaft, said second wheel having a positive drive surface about the total periphery thereof; and a work carrier coaxially arranged relative to said shaft, said work carrier including a friction follower extending to said first wheel and constantly containing said friction drive surface of said first wheel and a locking member extending for selective positive engagement with said second wheel at any engagement point on said second wheel defined by said positive drive surface.
Claim 3
Dependent Claim
13 words
The drive of claim 1 further including a plurality of said work carriers.
Claim 4
Dependent Claim
15 words
The drive of claim 2 wherein said work carriers are rotatably mounted on said shaft.
Claim 5
Dependent Claim
13 words
The drive of claim 1 wherein said second wheel is a ratchet wheel.
Claim 6
Dependent Claim
18 words
The drive of claim 4 wherein said locking member is a pawl pivotally mounted to said work carrier.
Claim 7
Dependent Claim
43 words
The drive of claim 1 further including a selective engagement mechanism fixed to said base and extending to said locking member to prevent engagement of said locking member with said second wheel at predetermined locations of said work carrier relative to said base.
Claim 8
Dependent Claim
26 words
The drive of claim 6 wherein said selective engagement mechanism is a cam and said locking member includes a cam follower in association with said cam.
Claim 9
Dependent Claim
38 words
The drive of claim 1 further including a stop retractably extending from said base, said stop extending from said base to block movement of said work carrier and being selectively retractable to allow movement of said work carrier.
Claim 10
Dependent Claim
73 words
The drive of claim 8 further including a selective engagement mechanism holding said locking member from said second wheel, said selective engagement mechanism including a cam surface retractably mounted relative to said base to hold said locking member from said second wheel, said cam surface being retractable with said stop to allow engagement of said locking member with said second wheel when said stop is retracted from blocking movement of said work carrier.
Claim 11
Dependent Claim
61 words
The drive of claim 1 wherein said work carrier further includes a clamping means for holding work, said clamping means having jaws articulated to receive and retain work, a spring for holding said jaws in one of the open and closed positions and a dog pivotally mounted on said work carrier for holding said jaws in the other of said positions.
Claim 12
Dependent Claim
30 words
The drive of claim 10 further including cam means fixed to said base to rotate said dog to open and close said jaws at predetermined locations relative to said base.
