Abstract
Abstract An item carrier for an item transport system wherein the carrier member is provided with means automatically adjustably movable as a result of the pendulum effect or tilt of the item effective to prevent accidental dislodgement or disengagement of the item from the carrier while simultaneously causing the tilt or pendulum movement thereof to continuously move the item into a tighter engaging position in the carrier with each tilt or swing.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
231 words
A carrier mechanism for transporting objects such as mail items from place to place for disposition at an intermediate or ultimate distination comprising, an irregularly shaped member having transport engaging means at one end thereof and object engaging means at the opposite end thereof, said object engaging means including oppositely disposed orthogonally arranged pivot support means and a backup anvil adjacent one of said support means, a plurality of item gripping (means) levers having a resilient surface portion disposed on (one of) said support means movable into and out of engagement with an item disposed between said item gripping means and said backup anvil, each of said item gripping means being capable of independent relative motion with respect to the other of said gripping means, and release means on the other of said support means including means engagable with the transport apparatus for resiliently causing said gripping means to engage an item for transport thereby and subsequently to release said item at the intermediate or ultimate destination thereof, said item gripping means being capable of relative movement with respect to said item whereby any pendulum tilt or rocking movement of said item causes one of said gripping means to hold said item while the item moves with respect to the other of said gripping means so that the (latter) item (to further engage) moves into tighter engagement with said gripping means.
Claim 2
Dependent Claim

A carrier mechanism for transporting objects such as mail items from place to place for disposition at an intermediate or ultimate distination comprising, an irregularly shaped member having transport engaging means at one end thereof and object engaging means at the opposite end thereof, said object engaging means including oppositely disposed orthogonally arranged pivot support means and a backup anvil adjacent one of said support means, a plurality of item gripping (means) levers having a resilient surface portion disposed on (one of) said support means movable into and out of engagement with an item disposed between said item gripping means and said backup anvil, each of said item gripping means being capable of independent relative motion with respect to the other of said gripping means, and release means on the other of said support means including means engagable with the transport apparatus for resiliently causing said gripping means to engage an item for transport thereby and subsequently to release said item at the intermediate or ultimate destination thereof, said item gripping means being capable of relative movement with respect to said item whereby any pendulum tilt or rocking movement of said item causes one of said gripping means to hold said item while the item moves with respect to the other of said gripping means so that the (latter) item (to further engage) moves into tighter engagement with said gripping means.
Claim 3
Dependent Claim
31 words
The invention in accordance with claim 1 wherein said anvil and said gripping means include resilient means operably interengagable upon relative motion of said release means with respect to said anvil.
Claim 4
Dependent Claim
32 words
The invention in accordance with claim 1 wherein said item gripping means comprises individual elliptically shaped members provided with resilient peripheral portions for operable engagement with the resilient means on said anvil.
Claim 5
Dependent Claim
38 words
The invention in accordance with claim 1 wherein said release means further includes an elongated rockable member having stop means engagable with said gripping means effective to limit the pivotal movement of said gripping means toward said anvil.
Claim 6
Dependent Claim
42 words
The invention in accordance with claim 1 wherein the resilient means of said anvil comprises a relatively flat flexible member having an irregular surface portion exposed for intimate contact with said gripping means when said gripping means is brought into engagement therewith.
Claim 7
Dependent Claim
40 words
The invention in accordance with claim 5 wherein said flexible member of said anvil is constructed to provide oppositely disposed parallel raised land portions for contact with the resilient portions of said gripping means when the latter engages said anvil.
Claim 8
Dependent Claim
41 words
The invention in accordance with claim 1 wherein said gripping means includes a pair of non-metallic elliptical members, the peripheral portion of each of which is channeled, undercut and grooved so as to receive a continuous element of resilient material therein.
