| 47 | Apparatus for processing porous and absorbent sheet material in bulk | US17251971 | 1971-08-17 | US3803882A | 1974-04-16 | BRENNAN G |
| A drum apparatus for maintaining a liquid bath in which sheet material of a porous and absorbent nature is processed includes a processing chamber adjacent an open end and a drainage chamber adjacent its other end which is closed. The drum is mounted for rotational movement about its longitudinal axis and for pivotal movement in a vertical plane. The drum is pivoted to a loading position and the sheet material is fed through the open end into the processing chamber. Fins in the processing chamber are adapted to work the sheet material in a liquid bath supplied to the drum during rotation of the drum in either direction. After the sheet material is processed the drum is pivoted to a discharge position for removal of the sheet material out through the open end.

| 48 | Helical shelf for rotary inclined processing tank | US3795121D | 1973-02-26 | US3795121A | 1974-03-05 | CRESSMAN F |
| A pair of helically shaped flat shelves each having a first rearward curving lip along a portion of its inner edge located in a generally cylindrical rotatable processing tank, such as a hide processing tank, with an axis of rotation inclined to the horizontal. Rotation of the tank about the axis of rotation causes the shelves to move thereby producing improved circulation of the hides in suspension in processing fluid in the tank. The circulating motion of the hides is down the walls of the tank along the shelves towards the rear and up the central portion of the tank towards the front. In addition to this improved circulation, the hides are also lifted up the walls by the motion of the shelves and dropped back into the processing fluid, thereby subjecting the hides to improved ''''scudding'''' action. This lifting and dropping action is dependent upon lips which curve from the inner edge of the shelves towards the rear of the tank. The degree of lifting action is also determined by the pitch of the shelves as well as the angle of inclination of the axis of rotation, and therefore the pitch of the shelves is varied in three different zones along the length of the tank to produce different lifting action in each zone. The junctions of the shelves with the rear end of the tank are filled to form smooth sloping surfaces and a deflection barrier provided across the rear end of the tank between the junctions to provide improved circulation of the hides in the tank. The shelves may also each have a second forward curving lip extending a second portion of its inner edge through a truncated cone shaped body portion leading to a front opening. Processed hides may be removed from the tank by reversing the direction of rotation of the tank. The hides are retained on the shelves by the second curved lips as they are carried forwardly along the shelves to the front opening.

| 49 | Treatment barrel | US3735611D | 1970-12-30 | US3735611A | 1973-05-29 | PILLARD C |
| Rotary barrel for treating materials, notably hides and skins, adapted to be rotated about an axis tilted to provide an upper bottom and a lower bottom shell, the barrel being rotatably supported by a pair of rollers and driven by one of these rollers, which are disposed adjacent the upper bottom for engagement with a race-forming annular ring rigid with the barrel, the lower end of the barrel being provided with a swivel bearing coaxial thereto. The barrel may have a cylindrical, biconical or cylindro-conical configuration, and be provided with internal pins, studs or bars of straight or helical profile for carrying along the materials to be treated, a drain cock being provided near the outer edge of the lower bottom, possibly with a discharge aperture formed in the wall of revolution adjacent to said drain cock, and a loading aperture formed in the free upper bottom shell, perforated plate means near the bottom inner corner for protecting the drain cock from clogging, and possibly an arrangement of helical ribs whereby rotating the barrel in one direction will perform the treatment while rotating same in the opposite direction will cause the treated materials to be discharged therefrom.

| 50 | Apparatus and process for treating hides | US3670534D | 1969-03-20 | US3670534A | 1972-06-20 | GOULD BRUCE MICHAEL |
| The hide-processing apparatus is comprised of a rotatable and axially inclined drum having two helical T-shaped blades fixed to its inside wall. The web of each blade is perforated. In treatment of hide, the drum is partially filled with a processing solution and with hide. Upon rotation of the drum in a tumbling direction, the hide is dehaired by being worked upon by the rotating blade and the removed hair is moved in an opposite direction to the movement of the hide and towards the open end of the drum. Upon rotation of the drum in a discharging direction, the treated hides are discharged through the loading end, yet, because of the perforations, most of the hide-treating liquid is retained in the drum during the discharging phase.

| Hides or similar sheet materials of a porous and absorbent nature are processed in a liquid bath contained within a drum mounted for rotation about an axis inclined from the horizontal. The drum includes a drainage chamber proximate a lower closed end and a processing chamber adjacent an upper open end. Drainage means extending into the drum along the drum axis are adapted to drain the liquid in the drum from the drainage chamber and liquid supply means are adapted to pass liquids into the drum whereby various baths having different chemical ingredients may be added and discharged during the process of the material. Spiral fins affixed to the inner wall of the drum and extending radially inward therefrom are adapted to work and treat the material maintained in the processing chamber when the drum is rotated in one direction and are adapted to move the material towards the open end when the drum is rotated in the other direction.
