IPC: G09F11/02
Filed: 1970-01-27
Abstract: 1288126 Changing signs W NOWICKI 27 Jan 1970 [30 Jan 1969] 4002/70 Heading G5C At least two groups of interchangeable plates 1, 2, 3, 4, or triangular cross-section have hinges 7 enabling them to revolve about axles 9 to selectively form one of a number of display areas when viewing surfaces of pairs of plates in each group lie in a common plane. The plates are resiliently urged away from each other by bumpers 14 engaging sprung angle levers 12, the two plates 1 and 4 forming the display area being prevented from hinging in upon one another by two stops 26, 27. The plates are supported at their lower ends an rollers 10 bearing on a plate 11 of frame 8. A disc 20, Fig. 13, also rotatable about axle 9, bears a plunger 23 which can reciprocate against the action of a spring 21. In order to change the display area, the disc 20 is rotated in an anticlockwise direction from the position shown until the action of a fixed spindle 15, attached to plate 1, on the oblique end of plunger 23 causes the plunger to lie behind the spindle 15, Fig. 14 (not shown). The direction of disc 20 is now reversed and the plunger 23 pushes spindle 15 to overcome the force of stop 26 and carry the plate 1 to the position previously occupied by plate 4, where it is held by stop 27. The sprung levers 12 cause the plates 2, 3, 4 to move round in a clockwise direction, plate 2 now being held by stop 26 in the position previously occupied by plate 1, the display area now being constituted by plates 1 and 2. The movement of disc 20 is achieved by gear 18 rigid with disc, engaging a reciprocating rack 29. A crank mechanism rotating about axle 43 causes the rack 29 to reciprocate, and is driven by a chain 46 from a motor (49), Fig. 20 (not shown).

Title: Improvements in stencil printing machines
IPC: B41F15/08
Filed: 1958-02-07
Abstract: 887,720. Stencil printing machines. VIDAL, .I. S. Feb. 7, 1958 [Feb. 11, 1957], No. 4038/58. Class 100(2) In a stencil printing machine the printing frame 3 is supported by rotatable bushes 5 having screw-thread engagement with screws 6 secured to the slide 2 which moves from one printing position to another, the bushes having formed thereon sorted sprocket wheels 1 driven by a chain 1a from a member 9 adapted to be driven, first in one direction, and then in the other, to raise and lower the printing frame. As shown, a flywheel 13 driven from a motor through reduction gearing to make one revolution for each printing cycle, drives a connecting rod 12 connected to a cylinder 11 slidable on an enlarged part 10 of a long rod 8 supported in fixed bearings. Compression springs 16, 17 are arranged on the rod 8 between the cylinder 11 and stops 14, 15, respectively, and pawls which are urged upwardly by springs are arranged below the rod 8 to co-operate with the stops 14, 15. In operation, assuming the cylinder 11 is moved to the left by the rod 12, the stop 14 is held by its pawl and the spring 16 compressed. On the continued movement of the cylinder 11 it releases the said pawl, the rod 8 is forced suddenly to the left by the energy of the spring 16, and a member 9 on the rod 8 drives the chain 1a by engaging the chain 1a: the frame 3 is thus raised from the slide 2. When the spring 16 is fully expanded, the opposite stop 15 is engaged behind its pawl, and the returning cylinder now compresses the spring 17, then releases it, and the chain la is driven in the opposite direction, causing the frame 3 to be lowered.

IPC: F26B13/10
Filed: 1928-02-13
Abstract: 285,378. Lambrette, A. Feb. 14, 1927, [Convention date]. Drying materials in long lengths.-In apparatus for drying fabrics, paper, &c. of the kind in which the material is conveyed through the drying-chamber in festoons upon loose sticks, the festoons are formed so that relative motion between the material and the feed roller A and the strikers is avoided; and the discharge roll q is rotated at such a speed that the tension in that part of the material between the roll q and the last stick is sufficient to move the stick between the endless bands r, t which convey the sticks to the supports a, a' at the feed end of the apparatus. The feed roll carries pulleys B, 0 connected by notched mechanism to the feed-roll shaft, the diameter of the pulley B being the same as that of the roll. Counterweighted cables pass over and under the pulleys B, C respectively and are connected to a common point on a chain D driven from, and at the same speed as, the chains b, b' which carry stops c, c<1> for picking up the sticks from the supports a, a<1>, and which convey the sticks to the chains h, h<1> in the drying-chamber. During the forward movement of the chain D the roll is rotated through the pulleys B at the same speed as the sticks and the pulley C rotates freely upon the shaft in the opposite direction, while during the return movement of the chain the pulley B rotates freely upon the shaft and the pulley C under the influence of the counterweight H rotates the roll in the opposite direction to deliver the material to form the next festoon. In a modification, the endless bands r, t deposit the sticks on guides c in the drying-chamber, and the sticks are fed in a step-by-step movement between the guides c, d by rods g reciprocated by cam-mechanism from a rotary shaft. The roll is provided with a single pulley m, Fig. 8, over which passes a counterweighted cable one end of which is connected to the end of a reciprocating link k moving in guides. The drying is effected by hot air which is circulated downwardly through the material and upwardly through sideheating compartments in the first part of the chamber and in the opposite direction in the later part of the chamber.
