Abstract: 1013. Lake, H. H., [Turner Tanning Machinery Co.]. Jan. 14. Hides and skins; raw and tanned, treating.-Relates to machines for treating hides, skins, and leather by rubbing or slicking blades and rolls, and comprises, more especially, means for treating that portion of the skin which lies around the end of the table or support by which it is carried through the machine. Fig. 1 shows the machine in sectional elevation, and Fig. 7 in plan. An endless carrier 21 passes over sprocketwheels 22, and serves to carry the supports or tables 23 through the machine. The skin is folded over the table, which carries it first between the spirally-bladed spreading - rolls 26, and then between the blades of the main working members or slickers 24, 25. The rolls 27 impart a final polish or rubbing to the skin. The following means are provided for treating the narrow strip of skin at the leading edge of the table, which would otherwise escape treatment :-At each side of the machine is a slide 31 moving between guides 30, and normally held by gravity at the lowest point of its travel. Each slide has a transverse groove 32, parallel to the conveyer 21. Guided in the grooves 32 are two shoes 34 connected by a cross-bar 33, which is normally held at the left-hand end of the grooves 32 by chains 38 and weights 37. Two carriers 44 are free to slide on the bar 33, and to the rearwardly-directed faces of the carriers are pivoted the slicker blades 42, which are formed with concave operative edges for the treatment of the skin which lies round the end of the table. The slicker blades are pivoted at their upper ends, and are spring-tensioned to hold them firmly against the advancing edge of the table. At the moment that the advancing table reaches the slicker blades, they are situated side by side towards the middle of the bar 33. The table carries the slicker blades along with it, the shoes 34 sliding in the grooves 32, and the weights 37 being lifted. At the same time, however, the carriers 44 are rapidly separated, ultimately reaching the position shown in Fig. 7, and during their movement the slicker blades wipe or scrape the skin folded round the advancing edge of the table. The separation of the carriers is effected as follows :-Each carrier is provided on its upper face with pins 49, Fig. 7, between which engage the ends 50 of two levers 51, 52, fulcrumed at 53, 54 to a carriage 55. The carriage is adapted to slide in an opening in a plate 55<a> which extends between the side standards of the machine. The levers 51, 52 are connected by links 57, 59, 59, of which the last-named is pivoted to the carriage 55 at 60. Chains 68, 69, carrying weights 66, 67, are attached to the levers 51, 52, and to the lever 51 is also attached a chain 61 which is connected to a lever 63, Fig. 1. As soon as the leading edge of the table reaches the slicker blades 42 a projection 671 at the other end of the table comes in contact with a shoulder on the lever 63, so as to draw the lever forward and separate the levers 51, 52 and carriers 44. When the carriers have reached the positions shown in Fig. 7, they are lifted clear of the table, the slicker blades passing through the notches 42. The carriers are lifted by means of projections on the chain 21, which actuate the angle levers 77. The angle levers engage extensions 76 of the slides 31, and lift the slides, crossbar, or carriers. The carriers rest on the table until it has passed from beneath them, when they drop into their working position in readiness for the next following table.
