Patent GB-588011-A (GB)
Title: Improvements in or relating to sewing machines specifically adapted for domestic use
IPC: D05B73/00
Filed: 1945-01-24
Abstract: 588,011. Sewing-machines. GEGAUF'S SOHNE AKT.-GES., F. Jan. 24, 1945, No. 1921. Convention date, April 11, 1944, [Class 112] [Also in Group XXV] Frames; lock-stitching by shuttles. In a domestic sewing machine, the under thread and feed mechanisms are arranged in a small arm, above the base, to allow of the mending or sewing of stockings, sleeves and the like; the arm projects as little as possible past the needle, and its end is embossed like a darning ball. The loop-taker shaft is arranged transversely of the arm and is oscillated by a rack and pinion; it is stated that the needle-bar may be capable of vibration to produce zig-zag seams. In the arrangement shown in Fig. 4, the shuttle-driver 5 is secured to an overhung shaft 6, which is mounted in a bearing in the side of the machine arm 4, and carries a pinion 7 meshing with a rack 8 arranged longitudinally of the arm and reciprocated by a link from a crank disc on a vertical shaft bevel-geared to the needle-bar driving shaft; the pinion 7 and shuttle driver 5 are held against endwise movement on the shaft 6 by a collar 6<1> and a disc 10 which overlaps the rack 8 to keep fluff and dirt out of the teeth. A protecting ring 11<1> is held against the shuttle race 11 by a U-shaped member 13'acting through a leaf-spring 12 or springs; this member is hinged at its lower edge on a pin 14 and is normally held in operative position by a bladespring catch. A door 17 in the wall of the machine arm is also hinged on the pin 14, and is held closed by a spring catch (see Group XXV). Feed. The four-motion feed mechanism, comprising a feed-bar 25 supported by an arm on a rock-shaft 28 and reciprocated by an arm 24 on a rock-shaft 46, receives its lifting motion from a cam surface on the face of the shuttle-driving crank disc engaging an arm on the end of the shaft 28. The feed movement is derived from a cam 42, Fig. 5, on the needle-bar driving shaft oscillating a lever 43 which is supported by a pin 44 in a slide-block carried a guide 48 in an angularly adjustable member 49, so that the inclination of the guide 48 determines the vertical movement of the lever 43 which is imparted to the rock-shaft 46 through an arm 45. The member 49 is adjusted by means of a lever 51 with an indicating scale 52, and its range of adjustment is limited, to an equal extent on either side of the mid-position, by a screw 54 entering more or less into a conical depression in the member 49.

Title: Automatically-reversible free-wheel or one-way locking devices
IPC: F16D41/10
Filed: 1937-01-22
Abstract: 492,587. Preventing reverse movement. IFIELD, R. J. Jan. 22, 1937, No. 1923. [Class 103 (i)] In a device allowing rotation in one direction only at a time, balls 15 or rollers between a surface 13 having opposed inclines and a cylindrical 'or disc surface 14, the former surface is biassed in one direction by spring means so that each ball ooac'ts with one incline to give looking in one direction until the torque exceeds a predetermined amount whereupon the parts of the device move against the spring bias to allow the balls to coact with the 'other inclines to give locking in the other direction. The spring means comprises a spring 23 between levers 22 having rollers 21 coacting with cams 20 fixed to the member 12 carrying the inclined surfaces. If the turning movement in the direction opposed by the balls 15 and member 12 exceeds a predetermined amount the rollers.ride over the cams 20 and the operation of the device is reversed. The device may be used with a restricted differential gear as described in Specification 471,325, [Group XXIV], and 16219/37, and one of these devices is shown arranged at each end of a motor vehicle differential gear to prevent reverse rotation of each wheel when the vehicle moves forward or forward rotation when the vehicle moves in reverse. In a modification two devices are arranged side by side and have a common member 12, which is biassed by a laterally acting spring detent. In further modifications the member 14 is shown as a. disc with a set of rollers on each side enclosed by a member 12 of annular channel form. In a further modification the member 12 is of disc form and the rollers are tapered. In a further modification the inclined surfaces 30 are formed as shown in Fig. 8 and one of the members carrying the surfaces is axially slidable against spring means to allow the necessary angular movement for the change of direction of locking. In Fig. 9 a number of members 12 are radially slidable against springs 36 and have incliried surfaces 30 engaging a roller 15.

Title: Improvements in or relating to the making of combined sound and picture records
IPC: G03B31/00
Filed: 1931-01-22
Abstract: 377,659. Combined sound recording and kinematograph apparatus; combined sound and picture films. KODAK, Ltd., Kingsway, London.-(Assignees of Jones, L. A. ; Kodak Park, Rochester, New York, U.S.A.) Jan. 22, 1931, No. 2123. Convention date, Feb. 5, 1930. Void [Published under Sect. 91 of the Acts]. [Class 40 (ii).] A photographic sound record is made on a kinematograph film by making a magnetic sound record synchronously with the exposure of the picture film, forming from the magnetic record by an electro-optical copying process a latent photographic record on a margin of the undeveloped picture film, and then transforming the two latent (sound and picture) images on the film into positive silver images by a photographic reversal process. Fig. 1 shows the combination of apparatus for magnetically recording sound on a strip 14, with a kinematograph camera 1, both machines being driven by a single motor 8. The take-up reel 17 for the strip 14 is driven by a friction pulley 16 and belt 15. For translating the record thus made into a latent photographic image on the picture film 9, the apparatus shown in Fig. 2 is used, in which a motor 8<1> drives the magnetic record 14 past electromagnets 19<1> in which current oscillations are generated. By means of an amplifying system 26, to which the magnets are coupled, light from a lamp 27 is thus acoustically modulated, and a record is made on the undeveloped picture film 9. The film is driven past the light slit 28 by the motor 8<1> through belts, pulleys, and a sprocket 23, the gearing being so chosen that the sound record is correctly synchronized with the picture record. The film 9 is finally submitted to a reversal process so as to transform the two latent images into positive silver images.
