Title: Shoe bottom roughening machine
IPC: A43D37/00
Filed: 1972-05-16
Abstract: 1335016 Boots &c MASCHINENFABRIK MOENUS AG 16 May 1972 [22 May 1971] 19371/72 Heading A3B In a shoe bottom roughing machine of the type in which a lasted shoe 1 is moved on a carriage 4 past one or more roughing tools 18 which are guided by a cam member on the carriage 4, the cam member is a composite cam whose effective profile varies with its height, and the cam follower which controls the tools 18 is automatically moved heightwise to select the cam profile appropriate to the size of shoe 1 in the. machine. As described the shoe 1 is mounted on the carriage 4 by means of a last pin 2' and toe rest 3. The toe rest is slidable lengthwise of the, carriage 4 and carries a bracket 5 having an inclined slot. An arm. 7 which carries a roller 6 is pivoted at one end to the carriage 4 and at its other end engages the inclined slot. Movement of the toe rest 3 into engagement with the shoe 1 therefore positions the roller 6 heightwise in accordance with the size of the shoe. When the carriage 4 moves along its guides 21 the roller 6 engages and depresses a ramp 8 which is held in its depressed position by a ratchet 23. The ramp 8 is connected at each side of the machine to a control arm 10 which carries a cam follower 11, thus setting the heightwise position of the roller 11 according to the size of the shoe. The composite cam includes two cam discs, one disc 14 corresponding to the smallest size of shoe, the other disc 15 corresponding to the largest. The discs 14, 15 are engaged at each side by intermediate rollers 13' connected to an inclined cylindrical member 13 which engages the cam follower 11. Thus, according to the height of the follower 11, the follower 11 follows a cam profile intermediate the profiles 14 and 15 depending on the size of the shoe. Each control arm 10 is connected by a link 16 to an arm 17 which carries the rotary wire roughening brushes 18. The depth of roughening can be adjusted by altering the position of a guide finger 20 adjacent each brush 18. The machine also includes an abrasive band 19 which roughens the toe and heel ends of the shoe.

In an hydraulically loaded roller producing a controlled pressure nip with a second roller, a cylindrical roller shell 13 in nip-correcting cooperation with a non-rotating centre shaft 15 is journalled at its ends on said shaft by selfaligning, as shown, spherical roller, bearings 18, and the centre shaft is supported at its ends by supports 24, (28) rockable about axes transversely of and spaced radially from the shell rotational axis, thereby accommodating shaft bending due to nip-correcting pressure reaction. The supports 24, (28) each comprise a depending lug 29 having a bottom surface rockable on a generally cylindrical bore 27 of a housing 25 (30) on a pedestal (26), (31). The support 24 is the outer one of three concentric sleeves, the inner sleeve 41 of which is lightly pressed on the centre shaft 15 and the intermediate sleeve 39 of which is journalled with respect to the other two sleeves by concentric sets of rollers 37, 40. The intermediate sleeve 39 acts as the sleeve driving means, being secured to a driving shaft 61, and being secured to the shell 13 by a flexible coupling 52 accommodating misalignment between the sleeve 39 and the shell. The coupling 52 comprises a flexible drive chain extending about and meshing toothed members 51, 55 secured to the sleeve 39 and the shell. The end of the centre shaft 15 remote from the driving shaft 61 extends through an end plate (32) of the housing (30) to receive a torque arm (35) by which the centre shaft is prevented from rotating and adjustably rotationally positioned. The centre shaft 15 carries a radially extensible deflection-controlling pressure shoe (16) rockably mounted on an elongated rectangular piston (17) and in sliding engagement with the shell 13. The centre shaft 15 is hollow to accommodate fluid pressure lines for the piston (17) and lubricating lines for the shell bearings

Apparatus for measuring high voltage transients comprises a capacitive potential divider Cl, C2 connected across the output of the transient producing circuit, and having a tapping point A connected to a voltage measuring circuit; and switching means S that connect the tapping point to a reference voltage between successive transients. The output of a pulse generator is connected, through pulse transformer T, across the capacitive potential divider C1, C2, and the tapping point A is connected through a double diode switch S to amplifying circuit V3, V4, and thence through rectifier D1 to a meter M. The switch S is operated by a flip-flop circuit V1, V2 driven by the pulse generator; a positive pulse being applied to the grid of V1 at the same time as the transient to be measured is fed to the pulse transformer T; a negative pulse is thereby supplied to the anode of diode D2 thus interrupting connection of the point A to earth through diode D3 and enabling the transient at A to produce a reading in M. On cessation of the transient, the tapping point A is again earthed through D3 to discharge the capacitive potential divider.
