Abstract
A de-hiding tool for use in slaughter houses in which a spring biases the reciprocating cutting blades into intimate facial contact to prevent debris from entering the driving mechanism, but achieves long life and low maintenance by interposing a low-friction element between the biasing spring and the nearest cutting-blade face, such element and the spring being carried in one cover of the tool coaxially with the cutting blades, the low-friction element being movable towards the nearest cutting-blade face under pressure from said spring, the tool being capable of adjustment to optimum operational speed by reason of an adjustable needle valve carried in the air channel to the tool.
Claims11
A de-hiding tool, including:
- a frame portion having first and second opposed faces;
- a hollow handle portion coupled to said frame portion;
- a tool-control valve portion coupled to said handle portion;
- an air motor carried in said hollow handle portion and coupled, pneumatically, to said tool-control valve portion;
- said air motor having a rotor;
- a pinion gear carried by said rotor in coaxial relationship thereto;
- blade-bearing means carried by said frame in said first face thereof;
- first and second toothed blades carried by said blade-bearing means, said first toothed blade being proximate to said first face of said frame;
- a wave spring;
- a low-friction insert;
- first cover means for covering said first face of said frame;
- said first cover means including a recess for receiving said wave spring and said low friction insert, said wave spring being positioned to bias said low-friction insert towards said first face of said frame;
- said low-friction insert, when said first cover is attached to said frame, forcefully engaging said second toothed blade which, in turn, becomes contiguous with said first toothed blade, whereby space between said first and second toothed blades is eliminated;
- and,
- drive means coupled to said pinion gear for driving said first and second blades in oppositely reciprocating directions.
