Abstract
Abstract Apparatus for sensing notches in the periphery of objects wherein an object is inserted into the apparatus until the leading edge contacts a detent frame. A plurality of precoded feeler arms is positioned to respond to a code; the code being the arrangement of notches in the leading edge of the object. A test signal is applied and if but only if the arrangement of notches corresponds to the predetermined code of the feeler arms, the detent frame will drop out of the path of travel of the object.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
128 words
A device for sensing the condition of the advancing edge of an object in a path of travel comprising: detent means for normally blocking said path of travel, a plurality of sensing means normally extending into positions in said path of travel in advance of said detent means and being movable by individual portions of the advancing edge of said object, said advancing edge at said detent means defining a coded arrangement of said sensing means, a corresponding plurality of coded means, each being integral with and positionable by an individual one of said sensing means, and means cooperating with said coded means for pErmitting said object to proceed along said path of travel if but only if said coded means are in a predetermined arrangement of positions.
Claim 2
Independent Claim
128 words
A device for sensing the condition of the advancing edge of an object in a path of travel comprising: detent means for normally blocking said path of travel, a plurality of sensing means normally extending into positions in said path of travel in advance of said detent means and being movable by individual portions of the advancing edge of said object, said advancing edge at said detent means defining a coded arrangement of said sensing means, a corresponding plurality of coded means, each being integral with and positionable by an individual one of said sensing means, and means cooperating with said coded means for pErmitting said object to proceed along said path of travel if but only if said coded means are in a predetermined arrangement of positions.
Claim 3
Dependent Claim
26 words
The device of claim 1 wherein: said sensing means is generally arcuate in shape, and each of said coded means counterbalances one of said sensing means.
Claim 4
Dependent Claim
26 words
The device of claim 1 wherein of each of said sensing means is mounted for independent rotation and is resiliently urged to said normally extended position.
Claim 5
Dependent Claim
29 words
The device of claim 1 wherein each of said sensing means is moved out of said path of travel by the presence of corresponding portions of said advancing edge.
Claim 6
Dependent Claim
17 words
The device of claim 1 wherein said detent means is resiliently urged into said path of travel.
Claim 7
Dependent Claim
23 words
The device of claim 1 wherein: said predetermined arrangement of positions corresponds to no notched corners on the advancing edge of said object.
Claim 8
Dependent Claim
24 words
The device of claim 1 wherein: said predetermined arrangement of positions corresponds to a specified notched corner on the advancing edge of said object.
Claim 9
Dependent Claim
23 words
The device of claim 1 wherein: said predetermined arrangement of positions corresponds to two notched corners on the advancing edge of said object.
Claim 10
Dependent Claim
43 words
The device of claim 1 wherein: each of said coded means has a rest state and an activated state, and each of said coded means is moved from its rest state to its activated state by the movement of its corresponding sensing means.
Claim 11
Dependent Claim
67 words
The device of claim 9 wherein: said coded means has operative and inoperative positions, said permitting means includes a plurality of permanent stops, each of said stops being associated with one of said coded means, and said arrangement of positions is defined as the location of the operative position of each coded means relative to its associated stop when said advancing edge is at said detent means.
Claim 12
Dependent Claim
49 words
The device of claim 10 wherein: each of said coded means includes a slot having an interior shoulder, said shoulder cooperating with the adjacent side of said slot to define said inoperative position, and said shoulder cooperating with the opposite side of said slot to define said operative position.
Claim 13
Dependent Claim
64 words
The device of claim 11 wherein said permitting means includes: means for testing the position of each of said coded means, said testing means being operable for moving all of said sensing means out of said path of travel and for retracting said detent means from said path of travel if but only if said coded means is in said predetermined arrangement of positions.
Claim 14
Dependent Claim
36 words
The device of claim 12 and further including: means for further advancing said object past said sensing means and said detent means if but only if said coded means is in said predetermined arrangement of positions.
Claim 15
Dependent Claim
104 words
The device of claim 12 wherein said testing means includes: first, second and third levers, said first lever for receiving a testing signal and transmitting said testing signal to said second lever, said second lever for simultaneously moving all of said sensing means out of said path of travel unless resisted by said inoperative position of at least one of said coded means, said second lever for further transferring a force to said third lever if but only if said second lever is not resisted by said coded means, and said third lever for retracting said detent means out of said path of travel.
Claim 16
Dependent Claim
37 words
The device of claim 12 wherein said testing means includes: means for simultaneously moving said plurality of sensing means out of said path unless resisted by said inoperative position of at least one of said coded means.
Claim 17
Dependent Claim
39 words
The device of claim 15 wherein said testing means further includes: means for moving said detent means out of said path unless said testing means is resisted by said inoperative position of at least one of said coded means.
Claim 18
Dependent Claim
24 words
The device of claim 15 wherein the resistance of said inoperative position is caused by the contact of said shoulDer and said permanent stop.
