FLETCHER, W., 5, Rampayne Street, Vauxhall Bridge Road, and FUCHS, A., 6, Newton Grove, Bedford Park, both in London. June 7, 1933, No. 16348. [Class 146 (ii)] [See also Group XVI] A machine for fastening together paper or like sheets by passing them between two rollers formed with teeth or projections on their coacting surfaces is provided with a displaceable guide or stop element mounted on a paper-supporting table by means of bosses at the ends thereof which pass through slots in the table, each boss having a spring member associated therewith which coacts with a series of depressions in the table to position the guide element. The guide element 15 is in the form of a bar mounted on a supporting table 10 by means of bosses 16 at each end engaging in slots in the table. Each boss projects below the table, and has secured thereto a springy metal plate 18 which extends on each side of the slot. The plate is formed at each end on its upper surface with a semi-spherical housing 19 for the reception of a ball bearing 20. The undersurfaoe of the table 10 is formed at each side thereof between the slots and side edges of the table with a series of depressions adapted to be engaged by the outer balls 20 on the metal plates 18 to hold the guide element 15 in adjusted position. The guide element is moved by gripping upstanding lugs 22 provided thereon. The fixed roller 1 is secured to a shaft 4 supported in a comparatively long bearing in a boss on the frame 3 of the machine, and is operated by a removable handle. The displaceable roller 2 is freely mounted on a pin 5 secured in a boss on a cross plate 6 mounted to slide on two studs 7 which pass through resilient buffers 8, of rubber, rubber composition, or coil springs, through clearance holes in the cross plate, and then screw into bosses on the frame 3. The buffers may be positioned in recesses in bosses on the plate 6. The plate 6 is pressed resiliently downwards by nuts 23 on the studs 7. Two arms 9 on the frame support the table 10, which is formed with an aperture through which the roller 1 projects. The undersurface of the cross plate 6 may be provided with resilient buffers adjacent the rear end thereof and at each side of the boss supporting the pin carrying the roller 2, to bear on the upper surface of the frame 3. The frame is formed with a clamping bracket 11 provided with a screw-threaded boss 12 which carries a clamping screw 13, between which and two rubber pads 14 on the arms 9, a support such as a table may be gripped.
