Abstract
Abstract A machine for effecting a processing treatment such as a cleaning operation on each of a series of animal carcasses sequentially fed to an operating station at which such a machine is disposed comprises a carcass-treating unit and a positioning means for moving the carcass-treating unit towards and away from each animal carcass disposed at the operating station in response to dimensional characteristics of each said carcass. The machine which is especially suited for cleaning hog heads after singeing depilation usefully includes a pneumatic means containing a volume of air which is compressed to an extent dependent on the reactive force exerted by each animal carcass on the carcasstreating unit of the machine so as to permit the desired variable movement of the carcass-treating unit of that machine away from each such animal carcass.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
27 words
A machine as claimed in claim 1 which includes a guideway in which said carcass-treating unit is mounted for guided movement between said upper and lower positions.
Claim 2
Dependent Claim
23 words
A machine as claimed in claim 2 which additionally includes a flexible drive linkage interconnecting said position control means and said carcass-treating unit.
Claim 3
Dependent Claim
84 words
A machine as claimed in claim 2 in which said position control means is pneumatically operable by said power operated means to urge said carcass-treating unit to move upwardly in said guideway but permits movement of said carcass-treating unit downwardly in said guideway on engagement of said carcass-treating unit with each said animal carcass sequentially by the compression of a volume of pressurized air enclosed within said position control means in response to such engagement of said carcass-treating unit and each said animal carcass.
Claim 4
Dependent Claim
90 words
A machine as claimed in claim 4 in which said position control means additionally includes a pressure relief means adapted to permit the escape of air therefrom in turn to permit further movement of said carcass-treating unit downwardly in said guideway when said force exerted by each said animal carcass on said carcass-treating unit exceeds a predetermined value, and said power operated means includes a unidirectional air supply means for the introduction of pressurized air into said position control means when the air pressure therewith falls below a predetermined value.
Claim 5
Dependent Claim
236 words
A machine as claimed in claim 2 in which said guideway is disposed generally vertically for movement upwardly and downwardly therealong of said carcass-treating unit, in which said carcass-treating unit includes a pair of axially spaced-apart brushes mounted on said carcass-treating unit for rotational engagement sequentially with each head of a series of animal carcasses suspended above said machine for sequential feed thereto, in which said carcass-treating unit is adapted to be urged downwardly along said guideway by engagement of said brushes thereof sequentially with each said animal carcass head, in which said position control means includes a piston disposed within a cylinder and operatively connected to said carcass-treating unit, in which said cylinder is operatively associated with an air chamber, in which said power operated means includes a unidirectional air input means for the supply of pressurized air into said air chamber to urge said brushes upwardly into engagement sequentially with each said animal carcass head for brushing engagement therewith, in which said brushes are urged downwardly by engagement with each said animal carcass head to compress said air within said air chamber, and in which said position control means includes an air relief valve adapted to permit the escape of air from within said air chamber in turn to permit further downward movement of said brushes when said force exerted by each said animal carcass head on said carcass-treating unit exceeds a predetermined value.
Claim 6
Dependent Claim
32 words
A machine as claimed in claim 6 in which said cylinder is hydraulically actuated and contains a body of hydraulic liquid in pressure communication with said air contained within said air chamber.
Claim 7
Dependent Claim
44 words
A machine as claimed in claim 7 which additionally includes a manually operable control valve adapted to control the flow of said pressurized air into and out of said air chamber in turn to permit manual control of the vertical position of said brushes.
Claim 8
Dependent Claim
21 words
A machine as claimed in claim 8 in which said piston is connected to said carcass-treating unit through a flexible linkage.
