Title: Improvements in or relating to fabric feeder mechanisms for sewing machines
IPC: D05B27/02
Filed: 1961-04-06
Abstract: 952,494. Sewing. NECCHI S.p.A. April 6, 1961 [May 14, 1960], No. 12371/61. Heading DIG, The feed dog of a sewing machine is displaced along a substantially rectangular path of longitudinal movement by a first mechanism, and a second mechanism displaces the feed dog laterally in one direction while the feed dog is performing its longitudinal feeding stroke and laterally in the other direction while the feed dog is performing its longitudinal return stroke. The needle 3, to which lateral movements can be imparted passes through an elongated throat 6, and the throat plate 5 is also formed with laterallyenlarged slots 7 for the teeth of the feed dog 9. The latter is fixed to one end of a feed bar 11, from which end an arm 12 depends to engage a feed lift eccentric 16 on a rotary shaft 17. A shaft 13 rigid with the other end of feed bar 11 is pivotally and slidably mounted in the forked upper end of a crank arm 20 at one end of a shaft 21. A crank arm 22 at the other end of shaft 21 is pivoted to a link 23. One end of the latter is pivoted to a Pitman 25 actuated by an eccentric on shaft 17, and the other end is pivoted to a block 27 slidable in a slot in a block 28 carried by a pivoted shaft 29. Arm 20 thereby imparts longitudinal feed movements which can be regulated by the angular movement of shaft 29. A block 30 on shaft 13 is formed with a slot engaged by a pin 32 on a lever 33 pivoted at one end to a fixed pin 35 and at its other end to a link 34. A pin 37, pivoted to the latter, has transversely fired thereto a pin 39 slidable in the arms of a yoke 42 pivoted on a fixed pin 46. A follower pin 44 on yoke 42 is urged by a spring 43 against a cam 45 on shaft 17. Transverse movements are thereby imparted to the feed dog, controllable by the position of pin 37 relative to pin 46. A lever 49, pivoted on a fixed pin 50, has a pin 48 engaged in a slot in link 34, an arm engaged with a cam 51 turnable by a handle 53 for manual adjustment of pin 37, and a pin 60 co-operating with a rotary cam 59 for automatic control of pin 37. Specifications 774, 294, 911, 338 and 916,491 are referred to.
Patent GB-613422-A (GB)
Title: Improvements in or relating to compound hydraulic brake compressors or the like
IPC: F15B7/04
Filed: 1945-05-17
Abstract: 613,422. Brakes. RYDE, A. HULL-. May 17, 1945, No. 12444. Convention date, June 25, 1943. [Class 103 (i)] A master cylinder assembly for operating brakes or the like comprises a piston 2 which forces fluid through the brake connection 10, in the initial stage, under the influence of hydraulic pressure exerted by the piston 15 in the bore 14, and, in the final stage of the brake application, under the influence of the pressure in the bore 14 and of the same pressure transmitted, as described below, to the space 23 behind the packing 4 carried by the piston 2. The pedal pressure is transmitted by a rod 42 to the piston 15 which is axially bored to receive a return spring 17 and a valve 29 in the form of a plunger having a head 36. When the rod 42 is first pressed in, the pistons 15, 2 move together because of the fluid trapped between them. As the pressure in the cylinder 14 rises, the pressure transmitted to the space 37 through the passages 32, 40 in the valve, becomes sufficient to overcome the opposing pressure and the spring 33, and the valve moves forward to align the passages 31 and groove 30 with the passage 27 leading to the space 23. The pressure in this space closes a valve 24 to shut-off the space 23 from the space 21 connected to the space 5 and reservoir 6 by passages 22. The space 38 is connected to atmosphere or to the reservoir 6 so that movements of the valve 29 are not impeded by pressure in this space. A check valve 11 is fitted at the brake connection 10, and fluid is supplied from the reservoir 6 to the cylinder 14 through a priming-valve 19. In a modification, the member 29 is provided with a spring- loaded valve in the passage 40, the valve having a restricted opening therethrough. The passages 32, 40 are of increased diameter, so that, when the pressure in the space 37 exceeds that in the bore 14, the valve lifts and permits the excess pressure to be vented quickly. The restricted opening in the valve permits normal functioning when the pressure in the space 37 is building up.

Title: Apparatus for printing and attaching labels to articles
IPC: B65C11/02
Filed: 1966-03-22
Abstract: 1,137,848. Labelling. SATO KIKI K.K. 22 March, 1966 [16 Sept., 1965; 17 Nov., 1965 (2)], No. 12449/66. Heading B8F. A label imprinter and dispenser has an applying device W at its delivery end, comprising a grooved roller 43 rotating about a fixed axis 42 with a second grooved roller 49 mounted on a frame 44 swingable upwardly about the axis 42 against the action of shock-absorbing springs. Flexible belts 50 run in the grooves on the two rollers to press labels 5 delivered from the dispenser on to articles to be labelled. The labels may initially be stuck consecutively on a backing strip 1, wound in a coil in the dispenser handle. On pressing a trigger 3 a rubber stamp 32, which may be set to the desired markings by a dial 16, prints those markings on to the label 6 resting on a support 13 adjacent the delivery position, and at the same time a brake 35 is raised from the strip by a spring 36. An ink pad 20 is displaced from beneath the stamp 32 to allow it to descend. When the trigger 3 is released the stamp 32 is raised again and the strip is fed forward by means of a unidirectional feed wheel 15. The pad 20 returns to its position beneath the stamp 32. As the trigger engages a lever A the brake 35 presses the strip at B against a fixed stop 39, preventing further feed. The backing strip 1 is stripped from the labels as they are fed between the applying device W and a guide 34, and is fed out of the dispenser as shown. A guide roller (54), Fig. 16 (not shown), may be provided instead of the guide 34 behind the applying device W.
Patent GB-125108-A (GB)
IPC: F41G1/393
Abstract: 125,108. Armstrong, Whitworth, & Co., Sir W. G., and Mole, E. H. June 4,1915, Sights and methods of sighting.-Relates to means for correcting the vertical lead given to an anti-aircraft gun according to the variation in the angle of sight of an approaching or receding tanget, and consists in an arrangement wherein the lead once applied is automatically corrected as the gun is elevated, by mechanism embodying a rack carried by a pivoted sight-bar and controlled by a parallel-motion system. As shown in Figs. 1 and 3, the automatic correction of the vertical lead is effected by means of mechanism connecting the sight-carrier V pivoted in the gun trunnion C to the sight-bar L, which is adjusted for range by means not described. The sight-carrier V is formed with a radial slot Y in which is mounted a slide-block carried by the spindle of a pinion U. The pinion U engages rack teeth formed within a rectangular opening Q<1> in a gear-wheel Q rotatably mounted upon an extension of the sightbar L and geared through an idler R to a fixed gear-wheel S of equal dimensions, so that an epicyclic motion of the pinion Q is accompanied by parallel motion of the slot Q'. When the spindle carrying the slide-block and pinion U is central with respect to the two rectangular slots, the sight carrier V and bar L move together in elevation without relative motion. When, however, the pinion U is adjusted towards one end or the other of the rack, by manual rotation, a relative displacement, such as is shown by the angle #1 in Fig. 3, is effected between the members L, V as the gun is elevated. This displacement varies from zero when the sights are horizontal, to a maximum when vertical. A modification is described in which a link parallel motion is substituted for the train of gearing Q, R, S.
