Abstract: 16,200. Maschinenfabrik M o e n u s Akt.-Ges. Oct. 31, 1907, [date applied for under Section 91 of Patents &c. Act, 1907]. Hides and skins, raw and tanned or tawed, treating.-In a serial table machine as shown in section in Fig. 3, the tables 10 are positively guided by a cam 11 so that, prior to their passage up between the two lower tools 4, one tool operates on the strip of hide bent over the top of the table, thereby ensuring treatment of the whole surface of the bide during one passage through the machine. The tools are suspended from adjustable pivots 2 by links 3, the lower ends of which are drawn together pair and pair by an arrangement of cords and weights (not shown). The inward motion of the tools is limited by the abutment of the links 3 on adjustable stops 13. The tables are kept upright while passing the edge-dressing tool by the engagement of rollers 41 with guide-bars 19, 20 on the machine end-frames 1, and presser rollers 14, carried by counterweighted swinging arms 15, may be used to hold the hides in position on the tables. The guides 19, 20 may be replaced by semicircular grooves formed in the end frames 1. The tables are suspended from the chains 9 by the arrangement shown in Fig. 9. One chain link is formed as a block 51, and its pins 52, 53 carry rollers 12 which run on the cam-surface 11, Fig. 3. The block is slotted to receive the bearing 46 of the pin 45 on which the table is suspended, and a screw 47, which traverses the bearing, enables the tables to be moved towards or from the warking-tools to take up wear. The working pressure can be adjusted by nuts 49 and springs 50. Fig. 5 shows a counter-pressure device for holding the tables vertical during the edge treatment comprising two elbow-levers 30, 31, the back arms of which are coupled by a weighted cord. The front arms bear upon the hide and upward extensions 34 of the tables. In the arrangement shown in Fig. 8, the elbow-levers are replaced by horizontal bars 36, 37, which are coupled at 39 and are pressed forward in long bearings 38 by a counterweighted elbow-lever 40. The position of the parts as the hide passes between the tools 4 is shown in dotted lines. Fig. 4 shows diagrammatically the path of the tables in a machine in which the complete hide receives double treatment. The table suspension for this form, Figs. 4<a> and 4<b>, consists of an enlarged chain-link 28 and rollers 12, the pivot 27 of the table 10 being carried in a bearing 25 which slides in a slotted block 24. This block is pivoted in the link at 22 and forms an abutment for the adjusting-nut 49 and pressure-regulating spring 50 as in Fig. 9. When the chain travels horizontally, the block is retained rigidly in an oblique position by the entry of the upturned lugs of the block under one or other of the clips 29, 29<a>, which are pulled inwards by springs but allow the bevelled lugs to enter under them. Cams on the framing move them out to release the blocks 24 when the chains become vertical. The Specification in the original form, as open to inspection under Section 91 (3) (a), comprises also an arrangement similar to that shown in Fig. 4, but with two single working-tools in place of two pairs. Each tool treats one half of the bent strip of hide at the top of the table and one flat vertlcal surface during the upward passage of the bide, which thus receives a single treatmeut during its passage through the machine. This subject-matter does not appear in the Complete Specification as accepted.
