Abstract
Abstract Apparatus for removing filter rod sections from a magazine in a filter cigarette making machine. The magazine has an outlet which receives a portion of a fluted drum so that, when the drum rotates, its flutes remove filter rod sections from the magazine. A yieldably mounted refuser roller is disposed between the drum and the magazine at the downstream side of the outlet to normally prevent the drum from removing sections which are not received in the flutes. If a section adheres to a section in a flute and displaces the refuser roller against the opposition of a spring, the roller or a lever for the roller actuates a switch which disengages a clutch serving to transmit torque to the drum and to other moving parts of the machine.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
171 words
Apparatus for removing rod-shaped articles which constitute or form part of smokers' products from a magazine which contains a supply of parallel rod-shaped articles, which has an outlet for evacuation of articles and which includes two walls flanking said outlet, comprising a conveyor including a portion adjacent said outlet and a plurality of parallel article-receiving means; means for driving said conveyor so that successive receiving means travel along said outlet in a direction toward and beyond one of said walls, thereupon toward and beyond the other of said walls and receive articles during travel between said walls; a refuser adjacent said outlet intermediate said conveyor and said other wall, said refuser being positioned to prevent said conveyor from removing articles which are not received in said receiving means whereby the articles which tend to leave said magazine while not received in a receiving means of said conveyor exert a force against said refuser; and means for arresting said driving means in response to exertion of a predetermined force against said refuser.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
31 words
Apparatus as defined in claim 1, wherein said conveyor is a rotary drum which is disposed below said magazine and said receiving means are flutes in the periphery of said drum.
Claim 4
Dependent Claim
13 words
Apparatus as defined in claim 1, wherein said refuser is a rotary member.
Claim 5
Dependent Claim
58 words
Apparatus as defined in claim 1, wherein said refuser is movable between a first position in which it prevents said conveyor from removing articles which are not received in said receiving means and a second position in response to exertion of said predetermined force, said arresting means being responsive to movement of said refuser to said second position.
Claim 6
Dependent Claim
18 words
Apparatus as defined in claim 4, further comprising means for yieldably biasing said refuser to said first position.
Claim 7
Dependent Claim

Claim 8
Dependent Claim
60 words
Apparatus as defined in claim 1, wherein said refuser is movable to and from a position in which it prevents said conveyor from removing articles which are not received in said receiving means and leaves said position in response to exertion of said predetermined force, said arresting means being responsive to a predetermined movement of said refuser from said position.
Claim 9
Dependent Claim
14 words
Apparatus as defined in claim 1, wherein said arresting means comprises an electric switch.
Claim 10
Dependent Claim
32 words
Apparatus as defined in claim 1, wherein said driving means comprises a clutch and said arresting means comprises a device for disengaging said clutch in response to exertion of said predetermined force.
Claim 11
