Filed: 1937-05-05
Abstract: 494,971. Sliding-seats. TIDDER, F. G. May 5, 1937, No. 12837. [Class 52 (ii)] In a chair in which the seat portion is slidable backwards and forwards, a catch which normally locks the seat in position is arranged to be released by the weight of a person sitting in the chair. The seat frame 16, Fig. 1, is slidably arranged on runners in the body 11 of the chair and the back frame 21 fits into recesses 18 in the seat frame and is pivoted on pins which may be accommodated in grooves in the body frame to enable the back to be readily removable. The seat is urged towards its rear position by a spring 35 and is locked automatically in this position by a catch 24. The weight of a person on the seat cushion 34 depresses and releases the catch by a push rod 31, which extends upwardly through the spring upholstery 32. The catch mechanism, Fig. 4, consists of a hook member 24 pivoted at 28 to a bracket 29 on a member 25 of the seat frame. The spring upholstery acting through the push rod 31 holds the hook in engagement with the abutment 26 on the side frame 27. The hook and abutment are so shaped that they engage automatically when the seat moves to its rear position. A modified form of catch, Fig. 5 (not shown), intended to be fastened to the side portions of the seat frame, employs a coiled tension spring to urge the catch towards the engaged position and a second abutment is formed to prevent the seat moving beyond the rear locked position. The Provisional Specification describes also an arrangement in which the spring holding the catch is also employed to urge the seat towards its rear position.

Title: Improvements in shearing machines
IPC: B23D15/02
Filed: 1954-05-04
Abstract: 753,763. Shearing. SCHLOEMANN AKT.- GES. May 4, 1954 [May 21, 1953], No. 12907/54. Class 83 (4). A bar shearing machine has an upper blade carrier 1 reciprocated in a vertical slide 20 in the frame by a lever 4 connected to a crank 5 and the upper blade carrier during its downward movement engages a stop 21 whereupon continued movement of the lever 4 lifts by means of a strut 10 the pivoted lower blade carrier 8 to effect shearing. The stop 21 is adjustable to suit the thickness of bar being sheared. Should the bar have an enlarged end the crank 5 is moved to lower dead centre to give maximum blade opening. Thereafter the crank 5 is oscillated with the upper blade carrier 1 in engagement with the stop 21 to shear the remainder of the bar into lengths. The Specification also describes a known machine in which the upper blade carrier is carried on a rod threaded into the frame and all the movement during shearing is made by the lower blade carrier, the strut 10 being in pin and slot connection with the lower blade carrier to allow the upper blade to be lifted for insertion of the bar.

Title: Improvements in mechanical toys, operated by gramophones
IPC: A63H13/00
Filed: 1921-05-09
Abstract: 183,287. Goodall, A. H. May 9, 1921. Mechanical toys.-In a mechanical toy operated by a gramophone, dolls or other toy figures move with a waltzing motion about the axis of the record table, the speed of rotation being controlled by a brake. Scenic and lighting effects are also provided. The device comprises a shaft B which is rotated by the gramophone either by friction between a pedestal C and the record D, or by clamping the pedestal to the pin F of the record table. A pulley G secured to the upper end of the shaft B drives, by means of a belt H, a pulley 0 secured to a spindle J which carries a forked support K for the dolls. The spindle J is journaled in bearings in a box A of circular or other shape which is itself free to rotate about the upper end of the shaft B. Thus the shaft B rotates the dolls about the spindle J and at the same time, the box is forced to rotate about the shaft B. The motion of the figures is controlled by an arm which presses against the underside of the box A, the pressure being regulated either by a spring or by a counterweight. Mirrors may be arranged around the apparatus to multiply the apparent number of dolls, and the whole device may be enclosed by a small stage with proscenium, drop-curtain, &c. Coloured lighting effects may be produced by an illuminant with coloured screens which are changed periodically by means of a stop on the gramophone table that strikes and rotates a small wheel.

Title: Device on an automatic pirn winder for depositing on a pirn skewer board the pirns ejected by the winder
IPC: B65H67/06
Filed: 1951-06-05
Abstract: 687,048. Collecting pirns from winding machines; stop-motions. MASCHINENFABRIK SCHWEITER AKT.-GES. June 5. 1951 [July 22, 1950], No. 13275/51. Classes 120(ii) and 120(iii) An automatic pirn winder is provided with a device for depositing on a pirn skewer board the pirns ejected by the winder, in which both the skewer board and a pirn ejection shoot are so connected via articulations to the frame of the winder that each of such units is pivotable about a stationary point. As shown, the shoot L and the skewer board H are mounted on the winder frame by universal joints and are so interconnected that pirns can be deposited successively on all the skewers without lateral movement of the board. A bracket 7 carrying shoot L is pivotable about an axis x 1  on a stirrup 3 which is itself pivotable on the machine frame about an axis y 1  at right angles to x 1 . Board H is carried on a frame 18 pivotable about an axis x 2  on a plate 14 which is itself pivotable on the machine frame about an axis y 2  at right angles to axis 17. Stirrup 3 is linked to plate 14 by a rod V 1  and bracket 7 to frame 14 by a rod V 2 , so that the shoot L and board H move simultaneously through equal angles about corresponding axes and shoot L always remains in alignment with the skewers. Cams 29, 32 operate respectively through follower levers 25, 36 (not shown) to rock the shoot about its two axes so that it comes in alignment successively with each of the skewers S on board H. Cam 29 is responsible for moving the shoot from row to row of the skewers, and cam 32 for moving it from skewer to skewer along each row. The cam surfaces are notched as at 33a so that the mouth of the shoot moves from skewer to skewer in a curved path which avoids the previously skewered pin. Cams 29, 32 are secured on the same shaft 28 as a ratchet wheel 53 which is advanced tooth by tooth by a pawl 62 operated by the control lever 58 of the winder gearbox at each pirn change. The number of teeth on ratchet wheel 53 is equal to the number of skewers on board H; after one revolution of wheel 53 all the skewers are full, and a feeler pawl 68 drops through a gap 69 in a ring 70 rotating with wheel 53, thereby causing a rod 76 to rise and operate the stop lever 78 of the winder. When the full skewer board has been replaced by an empty one, rod 76 is pressed down and the winder restarted by means of a control lever 57a.

Abstract: 1,163,054. Playback of magnetic records. MAGNAVOX CO. 28 March, 1967 [1 April, 1966], No. 13956/67. Heading G5R. [Also in Division H4] A transducer for reproducing information recorded on a magnetic medium such as a magnetic tape comprises a thin film of magnetic material disposed on one surface of a substrate, the magnetic material exhibiting the Kerr magneto-optic effect on plane polarized light reflected therefrom. In the embodiment described, Figs. 4 and 5, the transducer comprises an optical prism 200 designed to produce total internal reflection, a thin film of magnetic material 202, and a protective coating 204 of dielectric material of given thickness to protect the thin film 202 and to increase the magnitude of the reflected light. The transducer is disposed adjacent to magnetic tape 206 so that the information recorded thereon induces corresponding magnetic states in the thin film 202. Plane polarized light from source 208 via polarizer 212 is reflected from the thin film and coating 204 as shown in Fig. 5, and due to the Kerr magneto-optic effect the reflected light is elliptically polarized, the amount of rotation of the major axis of the ellipse depending on the magnetization of the magnetic tape. The reflected light is directed via an analyser 214 to a photo-detector 218, and since the amplitude of the output light energy is directly dependent on the rotation of the reflected light energy, and the contrast is inversely dependent on the ellipticity in the reflected light energy, the thin film 202 is of critical thickness (depending on the magnetic material) so as to enhance the rotation and to reduce the ellipticity of the light passing from prism 200. The thin film may comprise iron-cobalt, iron, germanium-iron or iron-magnesium fluoride.
