Skinning apparatus
First Claim
1. Apparatus for skinning hogs, including a rotatable drum, a skin clamp means operatively associated with said drum, and a skinning blade, said drum mounted on a rotatable drive shaft operatively connected with said skin clamp means for driving said drum through said skin clamp means, the improvement wherein said apparatus further includes;
- an end plate fixed at one end of said drum,an adjustable brake means mounted on said end plate of said drum, said adjustable brake means including,brake plate means,a spring-loaded pressure plate means for biasing said brake plate means against and into frictional engagement with said end plate, said brake plate means disposed between said end plate and said pressure plate means, andmeans for holding said brake plate stationary against rotation when said drum is rotated, for braking said drum.

Abstract
A substantially vertical drum skinning apparatus includes an improved knife, a cushioned drive and an overriding brake, all for improving a skinning operation. The knife is pivoted near the drum and is spring biased toward the drum to an adjustable stop, so that the knife is relatively rigid in line with the primary skinning force applied thereto. It is free to move slightly through a defined area and against a yieldable bias force for facilitating the clean removal of the skin. The drum is driven through a skin clamp, and a flexible cushioned drive coupling for transmitting force to the drum drive shaft and facilitating clamp engagement, and smooth removal of the skin is included. An improved overriding brake holds the drum positively until the skin is tightly clamped and is easily removable for changing worn brake plates.

11. Apparatus for skinning hogs, including a frame, a rotatable drum, a rotatable drive shaft extending axially through said drum, a skin clamp means operatively associated with said drum, and a skinning blade, said rotatable drive shaft operatively connected with said skin clamp means for driving said drum through said skin clamp means, the improvement wherein said skin clamp apparatus further includes,
an axially extending slot in a surface of said drum, an anvil mounted within said drum proximate said slot, a clamp shaft mounted within said drum parallel but offset from said drive shaft, first gears on said drive shaft, second gears on said clamp shaft, said first and second gears cooperatively intermeshing, a gripper element mounted within said drum on said clamp shaft for movement toward and away from said anvil to grip a skin flap therebetween, said drive shaft being operatively coupled to said gripper element for rotating said gripper element in one direction against said anvil and for rotating said drum in an opposite direction through said skin flap clamp means, wherein said drum is stationary throughout initial movement of said drive shaft and said clamp shaft, and wherein said drum turns in said opposite direction in response to said gripper element rotating in said one direction into operative gripping engagement with a skin flap between it and said anvil, and said apparatus further including a stop element mounted with said gripper element for movement therewith, said stop element disposed to engage said drive shaft when said drive shaft rotates in said one direction to rotate said gripper shaft in a said opposite direction for rotating said drum in said one direction.

14. Apparatus for skinning hogs including a frame, a drum means mounted for rotation about a longitudinal drum axis, and having a cylindrical skinning engaging surface, a skin flap clamp in said drum means for holding a skin flap of a hog, a skinning knife means mounted proximate said skin engaging surface of drum means and having a longitudinal knife edge parallel to said axis and disposed at a position spaced from said surface a distance approximately equal to a thickness of a hog skin, and means yieldably biasing said knife edge toward said skin engaging surface, the improvement wherein,
said knife is pivoted to said frame on a pivot axis approximately in line with said knife edge and the direction in which skin is pulled toward said knife edge, said pivot axis disposed on the same side of said knife means as said drum means.
