Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
249 words
A cyclic article transfer apparatus comprising a framework, a stationary arm fixedly secured to the framework; a first shaft rotatably supported by one end of said arm; a first rocking arm fixedly secured at one end to said first shaft for rocking movement in one and opposite directions with respect to said stationary arm; a second shaft fixed to said stationary arm and extending within said first shaft; a motion transmission means fixedly mounted on said second shaft; a third shaft rotatably supported by the other end of said first rocking arm; said a motion transmission means fixedly mounted on said third shaft; said motion transmission means on the second shaft and said motion transmission means on the third shaft being operably connected to each other; a second rocking arm fixedly secured at one end to said third shaft for rocking movement in one and opposite directions with respect to said first rocking arm; a fourth shaft fixedly secured to said other end of the first rocking arm and disposed within said third shaft in concentric relation to the third shaft; a motion transmission means fixedly mounted on said fourth shaft; a fifth shaft rotatably supported by the other end of said second rocking arm; a motion transmission means fixedly mounted on said fifth shaft; said motion transmission means on the fourth shaft and said motion transmission means on the fifth shaft being operably connected to each other; and an article retaining holder operably connected to said fifth shaft.
Claim 2
Dependent Claim
249 words
A cyclic article transfer apparatus comprising a framework, a stationary arm fixedly secured to the framework; a first shaft rotatably supported by one end of said arm; a first rocking arm fixedly secured at one end to said first shaft for rocking movement in one and opposite directions with respect to said stationary arm; a second shaft fixed to said stationary arm and extending within said first shaft; a motion transmission means fixedly mounted on said second shaft; a third shaft rotatably supported by the other end of said first rocking arm; said a motion transmission means fixedly mounted on said third shaft; said motion transmission means on the second shaft and said motion transmission means on the third shaft being operably connected to each other; a second rocking arm fixedly secured at one end to said third shaft for rocking movement in one and opposite directions with respect to said first rocking arm; a fourth shaft fixedly secured to said other end of the first rocking arm and disposed within said third shaft in concentric relation to the third shaft; a motion transmission means fixedly mounted on said fourth shaft; a fifth shaft rotatably supported by the other end of said second rocking arm; a motion transmission means fixedly mounted on said fifth shaft; said motion transmission means on the fourth shaft and said motion transmission means on the fifth shaft being operably connected to each other; and an article retaining holder operably connected to said fifth shaft.
Claim 3
Dependent Claim
160 words
The cyclic article transfer apparatus as claimed in claim 1, including means for driving said first shaft in one and opposite direCtions comprising a drive shaft adapted to rotate continuously in one fixed direction; a lever fixedly connected to said drive shaft; a connecting rod; a link connecting one end of said rod to said lever; a chain for driving said first shaft, the other end of the rod being connected to the chain; a disc cam fixedly secured to said framework in concentric relation to said drive shaft; a roller pivoted to said link and riding along the outer periphery of said disc cam; said disc cam having diametrically opposite cam faces on its outer periphery, each having a radius greater than that of the remainder of disc cam, and two cams fixedly secured to said framework at positions apart from said cam faces of the disc cam respectively by a distance corresponding to the diameter of said roller.
Claim 4
Dependent Claim
63 words
The cycle article transfer apparatus as claimed in claim 1, in which a rod extends from said fourth shaft which extends through said third shaft; said rod being held on opposite sides by inwardly biased springs and a check valve engageable with the lower end of said rod and serving to allow an emergency stop and control air to escape into the atmosphere.
