Abstract
Abstract Apparatus for weighing fowl hanging from shackles of a continuously moving overhead conveyor, having a plurality of balance arms extending radially outwards from the vertical central axis of the apparatus and being pivotably supported by slide blocks mounted on vertical guide bars rotating about the central axis and driven by the overhead conveyor. The outer ends of the balance arms are adapted, while moving along with the conveyor at the same speed, to catch and lift the shackles so that they are no longer connected with the conveyor, by moving the slide blocks upwards, and the inner ends of the balance arms are adapted to come to bear on a load cell located in the central axis when released by a locking member.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
113 words
Method for weighing birds, which hand from shackles of known weight carried by a continuously moving overhead conveyor, comprising the steps of: moving a pick-up member along in synchronization with said conveyor during part of its path; additionally moving said pick-up member relative to said conveyor, so that it will lift up a said shackle and disconnect it completely from said conveyor; transmitting, without any substantial relative movement or friction, to a load cell or other measuring device the force exerted on said pick-up means by the combined weights of said shackle and the bird it carries, for measuring said force; and finally releasing said shackle again to reconnect it with said conveyor.
Claim 2
Dependent Claim
113 words
Method for weighing birds, which hand from shackles of known weight carried by a continuously moving overhead conveyor, comprising the steps of: moving a pick-up member along in synchronization with said conveyor during part of its path; additionally moving said pick-up member relative to said conveyor, so that it will lift up a said shackle and disconnect it completely from said conveyor; transmitting, without any substantial relative movement or friction, to a load cell or other measuring device the force exerted on said pick-up means by the combined weights of said shackle and the bird it carries, for measuring said force; and finally releasing said shackle again to reconnect it with said conveyor.
Claim 3
Dependent Claim
133 words
Apparatus for weighing birds, which hang from shackles of known weight carried by a continuously moving overhead conveyor, comprising: a frame; pick up means movably supported within said frame; first moving means for moving said pick-up means along in synchronisation with said conveyor during part of its path; second moving means for additionally moving said pick-up means relative to said conveyor, for gripping and lifting a said shackle to disconnect said shackle completely from said conveyor; a load cell or other weighing device supported by said frame; means for transmitting, without any substantional relative movement or friction, to said load cell the force exerted by the combined weights of said shackle and the bird it carries, for measuring said force; and means for finally releasing said shackle to reconnect it with said conveyor.
Claim 4
Dependent Claim
133 words
Apparatus for weighing birds, which hang from shackles of known weight carried by a continuously moving overhead conveyor, comprising: a frame; pick up means movably supported within said frame; first moving means for moving said pick-up means along in synchronisation with said conveyor during part of its path; second moving means for additionally moving said pick-up means relative to said conveyor, for gripping and lifting a said shackle to disconnect said shackle completely from said conveyor; a load cell or other weighing device supported by said frame; means for transmitting, without any substantional relative movement or friction, to said load cell the force exerted by the combined weights of said shackle and the bird it carries, for measuring said force; and means for finally releasing said shackle to reconnect it with said conveyor.
Claim 5
Dependent Claim
73 words
Apparatus according to claim 2 in which said pick-up means comprise at least one pivotable balance arm, radially extending from and supported for rotation about the vertical center line of said frame, the outer end of said balance arm being adapted for gripping and lifting free said shackle, and the inner end of said balance arm being adapted for coming to bear on said load cell, which is located in said center line.
Claim 6
Dependent Claim
45 words
Apparatus according to claim 3, further comprising locking means for preventing said inner end of said balance arm from bearing on said load cell until said shackle is stabilized on said outer end of said balance arm and the same force is to be measured.
Claim 7
Dependent Claim
37 words
Apparatus according to claim 3, in which said balance arm is pivotably supported at a point intermediate its ends by a slide block, which is slidably mounted on a vertical guide means rotating about said center line.
Claim 8
Dependent Claim
43 words
Apparatus according to claim 5, in which said second moving means comprises a follower on said slide block and co-operating with a stationary cam track for moving said slide block and said balance arm up and down, for lifting and releasing said shackle.
