Abstract
A dehider having a novel housing and blade gear assembly and a novel bearing and blade grease system. The novel housing and blade gear assembly permits the dehider's head to be easily disassembled and reassembled for blade changing or sharpening purposes while insuring alignment of the dehider's dual blades upon reassembly. The dehider's novel bearing and blade grease system allows the dehider's bearings to be greased from exterior of the dehider's head, and allows the cavity between the hollow ground dual blades to be provided with grease interiorly thereof also from exterior of the head, i.e., without disassembly of the dehider's head.
Claims23
A flaying tool having two blades in contact with one another, said blades being movable relative one to the other on a common blade axis, said tool comprising
- a first housing and a second housing
- a first blade gear shaft and a second blade gear shaft, one of said blades being mounted on said first shaft and the other of said blades being mounted on said second shaft, said first shaft being fixed to said first housing and said second shaft being fixed to said second housing,
- first bearings between said blade and said first shaft and second bearings between said second blade and said second shaft, and
- a grease system for at least one of said shafts, said system comprising a bore in said shaft, the exterior end of said bore being connectable with a grease injecting apparatus exterior of said housing, and the inner end of said bore being connected to said bearings and an interior cavity defined between two blades so that grease injected into said shaft's bore supplies grease for said bearings and for said interior cavity.
A flaying tool having two circular blades mounted on a common axis, said blades being in contact one with another during relative motion therebetween, said tool comprising
- a left housing and a right housing,
- a left blade gear assembly connected to said left housing and a right gear assembly connected to said right housing, one of said blades being connected with said left assembly and one of said blades being connected with said right assembly, said gear assemblies being separate one from the other,
- an alignment pin coaxially aligned with one blade and connected to that one of said blade gear assemblies for said one blade,
- structure defining a bore coaxially aligned with the other blade and connected to that other of said blade gear assemblies for said other blade, said pin and said bore being received in assembled relation to maintain coaxial alignment of said blades upon assembly of said left and right housings, but not preventing axial disassembly of said housings, and
- connector means for connecting said left and right housings in assembled relation, said connector means being located beyond the periphery of said circular blades and not being coaxially aligned with said blades.
A flaying tool having first and second blades in contact with one another, said blades being movable relative one to the other on a common blade axis, said tool comprising
- a left housing and a right housing, said housings being assembled one with the other to establish a head within which said blades are carried,
- a first blade gear connected to said first blade and a second blade gear connected to said second blade, each of said drive gears being spaced from its respective blade by a spacer sleeve,
- a first gear shield interposed between said first blade gear and said first blade, and a second gear shield interposed between said second blade gear and said second blade, each of said blade shields being immobilized relative to said housing, each of said blade shields defining a port adapted to cooperate with a related spacer sleeve for preventing significant flow of foreign matter therebetween, and each of said blade shields including a flange at the inner ends thereof adapted to cooperate one with the other to establish a sealed cavity within which said blades move when said tool is assembled, said shields cooperating to prevent significant flow of foreign matter in the blade cavity as defined by said shields from flowing into the housing cavity as defined by said housings.
