Poultry defeathering apparatus
A poultry defeathering apparatus comprising a compression plate with a central aperture operationally associated with a hub drive shaft of a feather plucking machine, wherein the compression plate is secured to the hub drive shaft, a finger plate operationally associated with the hub drive shaft and the compression plate, the finger plate includes a central aperture, an annular abutment ring operationally associated with the central aperture, a plurality of finger apertures surrounding the central aperture, a plurality of fingers secured to the finger plate by insertion through the finger plate, with the body extending through a finger aperture, wherein the hub drive shaft is secured to the finger plate and wherein the oversized base of each finger is compressed between the compression plate and the finger plate and a mounting bolt secured on the finger plate within the mounting hole of the hub drive shaft.
1. A poultry defeathering apparatus consisting of:
a compression plate comprising:
a front side;
a back side;
a central aperture operationally associated with a hub drive shaft of a feather plucking machine;
wherein the hub drive shaft has a mounting hole;
wherein the compression plate is secured to the hub drive shaft by inserting the hub drive shaft through the central aperture;
a finger plate operationally associated with the hub drive shaft and the compression plate, the finger plate consisting of:
a front side;
a back side;
a central aperture;
an annular abutment ring secured to the front side of the finger plate and operationally associated with the central aperture forming a recessed opening on the back side of the finger plate;
a plurality of finger apertures surrounding the central aperture;
a plurality of fingers comprising an oversized base and a body extending from the base;
wherein each finger is adapted to be secured to the finger plate by insertion through the back side of the finger plate, with the body extending through a finger aperture and through to the front side of the finger plate and the oversized base being retained on the back side of the finger plate,
wherein to the hub drive shaft is secured to the finger plate by insertion into the recessed opening and engaging the annular abutment ring; and
wherein the oversized base of each finger is compressed between the compression plate and the finger plate and held substantially stationary during use; and
a mounting bolt secured on the front side of the finger plate within the mounting hole of the hub drive shaft.
2. The poultry defeathering apparatus of claim 1 wherein the compression plate is secured to the hub drive shaft with the assistance of a fastener.
3. The poultry defeathering apparatus of claim 1 wherein the fingers are tapered beginning at the base and decreasing in size as the body extends away from the base.
4. The poultry defeathering apparatus of claim 1 wherein the base of each finger has a shape selected from the group including: flat, convex, concave, or a combination thereof.
5. The poultry defeathering apparatus of claim 1 wherein the fingers are made of a natural rubber, a synthetic rubber, or a combination thereof.
6. The poultry defeathering apparatus of claim 1 wherein the fingers are made from a material selected from the group consisting of styrene-butadiene rubber, isoprene rubber, butadiene rubber, ethylene-propylene rubber, butyl rubber, chloroprene rubber, nitrile rubber, and combinations thereof.
