Filed: 1944-08-30
Abstract: 580,328. Rolling. FREDERICKS, M. A. Aug. 30,1944, No. 12446. [Class 83 (iv)] Relates to the cold rolling of sheets and consists in means provided be. hind the rolls to receive the sheet and raise it for return over the top roll. A base structure comprises longitudinal members a, a', a<2> and transverse members b, b<1>, b<2> and is provided with wheels c running on fixed rails d. Bosses k <5> attached to a fixed part of the mill carry feed screws k that engage driven nuts l mounted in the base structure and chain geared to a driving wheel 45 on a countershaft 16a driven from a main shaft 16 through gear trains 37 or 41 providing for an out- and in-feed of the base structure from the mill. The trains drive through clutches 39 and 44 controlled by a sleeve 16c connected by a spider 63 to a rod 62 sliding within the section 16b of the countershaft under the control of dogs 64, 65 actuated by a sleeve 66 traversed by a yoke connection from a block 67a sliding on rods 68 and provided with rack teeth 67b meshing with a segment 69 oscillated through bevel gearing from a rock-shaft 73 having an arm engaged by dogs 76, 76a, secured to the mill floor. The main-shaft 16 is driven from a motor 19 through a clutch 18 actuated through gearing 30 by a solenoid 20 manually excited to start the movement of the base structure away from the rolls and automatically switched off at the end of the return movement. The nuts l also have chains driving further nuts n on screws m secured to a trestle structure having legs g carrying wheels g2 running on rails f on the base. The screws m and k have threads of opposite hand so that the trestle and base structures move in the same direction. Rails h on the trestle structure match up with the stripper i and receive the rolled sheet. After the sheet has been traversed clear of the rolls, rails 12 carried by telescopic supports t<2> lift the sheet from the rails 12 and deliver it to rails (not shown) above the top roll for return to the feed side of the mill. The lower sections t<1> of the supports are pivoted at t<3> in lugs on short sleeves u<1> on tubular shafts r supported in bearings on the base structure. There are three sets of arms spaced at 120 degrees apart round the shaft and the ends t<4> project through slots in the sleeves to engage a cam r3 on a central non-rotating rod r<1>. The sections t<1> are linked by rods v<1> to which are attached collapsing springs z. Links w pivoted to the rods v<1> are pivoted to pistons t<5> attached to the parts t<2> and sliding in the parts t<1>. Further links 13 are controlled by cams 13c to assist in the pivotal movement. The shafts r are driven in synchronism with the movement of the base structure by gearing from the shaft 16. As the arms rotate that row coming into position under the sheet are swung and extended to effect the required movement of the sheet after which they are again collapsed.

Title: Improvements in or relating to dobbies for looms for weaving
IPC: D03C1/14
Filed: 1934-04-27
Abstract: 437,732. Loom dobbies. PLACE, J. H., Gothic Lodge, Romiley, near Stockport, Cheshire, and BRUNDRETT, H., 37, Woodlands Road, Cheetham Hill, Manchester. April 27, 1934, No. 12698. [Class 142 (i)] In dobbies employing perforated paper bands for controlling the healds in place of or in addition to the usual dobby lags, the paper strip p<2> is passed around a curved plate p on a pair of spaced slides o which are moved towards and away from a series of needles n<1> by a forked lever r operatively connected to the Tee lever of the dobby. The lever r straddles a shaft p<1> which is provided with spiked discs for engaging the pattern band and carries at one end two oppositely toothed ratchets for engagement with relatively stationary pawls to move the strip in one direction or the other. The needles n<1> co-operate with a series of tumbler levers m carried by a vertically movable trough k and adapted normally to underlie shoulders f<4> on the dobby indicator levers f<2>, f<3>. When the pattern band is advanced to operative position, those needles moved endwise swing their associated levers m clear of the indicator levers whilst the remaining tumbler levers are left in position to actuate the corresponding indicator levers j<2>, f<3> on being raised by the member k. The trough is actuated by a lever t<1> having a projection t which co-operates with two relatively slidable notched bars s<2> u adapted to be reciprocated by a lever s connected to the slide members o, the arrangement of the notches being such that the trough is held raised at each actuation until both upper and lower draw hooks e, e<1> have been actuated. A regulated shed opening is obtained by connecting the Tee lever to a sleeve 3, Fig. 4 that is movable axially by the action of a pin 5 in the groove of a rotary block 6, the concentric portions 81 of which give the requisite dwell. The rock shaft comprises a hollow shaft j<1>, Fig. 5, and an axially movable shaft j<4> extending therethrough, the former having two end levers j<2>, j<3> that can be engaged respectively by the bosses j<7> of levers j<5>, j<6> on the latter, one or other of the leyers j<5>, j<6> being moved into operative position by rotating a nut j<8>. The levers j<5>, j<2> constitute the power driven Tee lever whilst the lever j<6> is connected by chain gearing to a manually operable wheel. The paper strip attachment may be put out of action by actuation of a clutch. The Provisional Specification also describes tumbler levers that can be moved vertically about their pivots by a vertically movable trough actuated by a lever that is rocked by a spring and a pivoted trigger on a horizontally movable slide.

Title: Improvements in or relating to the cleaning of fabric filters
IPC: B01D35/16
Filed: 1964-03-25
Abstract: 1,020,102. Cleaning fabric filters. MASCHINENFABRIK BETH G.m.b.H. March 25, 1964 [April 30, 1963], No. 12735/64. Heading B1T. In a method of cleaning two or more fabric filters housed in different filter chambers by periodically conducting dust-free scavenging gas through the filter in a direction opposite to that of the flow of dust-laden gas, by closing the suction pipe through which the gas cleaned by the filter is removed and opening the scavenging gas supply pipe, subsequently opening the suction pipe and closing the scavenging gas supply pipe whereupon the cleaned filter is operated again, the suction pipe is opened in at least two stages. The dust-laden gas pressure thus builds up gradually so that the filter fabric is spared. The pressure builds up still more gradually if the stages of the suction pipe opening are unequal, increasing in size from the first to the last. The change-over may be rendered smoother still by closing the scavenging gas supply pipe in at least two stages after completion of cleaning. A suitable mechanism for effecting the above operations is shown in Fig. 2, an intermittently driven camshaft 1 rotating a cam pair 2 in the direction of the arrow, the cam 2a displacing a fork 3 to the left and this causing a bell-crank lever 5 to rotate clockwise and thus displace a shift rod 6 and a shift lever 7 so as to partially open a flap 9 in the suction pipe. At the same time, a counterweight 13 at one end of a bell-crank lever 11, the other end of which bears against a driver lever 10 coupled to the shift lever 7, causes partial closing of a flap 12 in the scavenging gas supply pipe. The subsequent step in the rotation of the camshaft I brings about complete opening of the suction flap 9 and complete closing of the scavenging gas supply flap 12. A toggle spring 8 which acts in a closing direction on the shift lever 7 ensures that the subsequent closing of the suction flap 9 and opening of the scavenging gas supply flap 12 are completed in a single operation. In the Fig. 2 position of the mechanism, the partially open suction flap 9 is prevented by the cam 2a from being closed by the action of the spring 8.
