Title: Improvements relating to signalling devices for toys
IPC: A63H17/32
Filed: 1959-02-24
Abstract: 868,838. Audible signalling apparatus; diaphragm vibrators. MULLER, W. H., [trading as SCHREYER & CO]. Feb. 24, 1959, No. 6349/59. Classes 13 and 118. A circuit for energizing a horn on a toy motor car comprises means for applying two different voltages in succession to the horn when the horn operating member is depressed, the horn comprising an electrically-actuated vibrating diaphragm, the pitch of which varies with the voltage applied thereto whereby the horn is made to sound two notes in succession. In the arrangement shown in Fig. 1, depression of the horn button 14 mounted on the steering column 12 causes lever 10 to be rotated, thereby closing contacts 17 and also releasing clockwork-driven cam 7 to close contact pairs 3, 4 and 5, 6 alternately, whereby the audible signalling device 1 is energized alternately from battery 15 and batteries 15 and 16 connected in series. Modified forms of switching circuits are described; in one Fig. 4 (not shown), depression of the horn button causes a moving contact to engage in succession with two fixed contacts thereby causing the two notes of the horn to be sounded. In another arrangement, Fig. 5 (not shown), depression of the horn button effects rotation of a lever which closes pairs of contacts in succession. Fig. 7 shows a construction of multi-tone audible signalling device which may be used for the horn; the device comprises a main diaphragm 64 and two additional diaphragms 65, 66 which are mechanically coupled to the diaphragm 64 by springs 67, 68. The smaller diaphragms 65, 66 are also provided with horns 70, 71 respectively and are carried together with the main diaphragm 64 in a housing 69.

Title: Automatic adjuster for vehicle brakes
Inventor: HARRISON ANTHONY WILLIAM
IPC: F16D65/56
Filed: 1963-02-16
Abstract: 1,068,173. Automatic brake adjustment. GIRLING Ltd. Feb. 6, 1964 [Feb. 16, 1963], No. 6382/63. Addition to 1,050,483. Heading F2E. A brake having two separate means of application, one by a hand lever, has automatic wear adjustment means effected by the angular movement of the hand lever and coupled through a slipping clutch to an intermediate member which is held against angular movement by the hand brake load, a spring effecting angular movement of an adjusting member when the intermediate member is released, a ratchet device being provided for preventing or limiting reverse movement of the limiting member. In a disc brake, a friction pad is applied in service braking by an hydraulic piston acting directly on the end of a nut 13 screwed on to a plunger 14 bearing on the pad, and is applied for parking by a hand lever connected by a link 27 to rotate member 25 which is moved forward by the ball and ramp device 29, 30 to carry with it the race 23, sleeve 21 and flanged nut 13. The ring 25 has a split bush 26 frictionally gripping sleeve 21 which is prevented from rotating with the ring, when the hand brake is applied, by pawl-andratchet 36, 38, the bush 26 slipping on the sleeve 21. A spring 41 engages the pawl and is a close fit on the end of nut 13. On hand brake release the ring moves little relatively to the sleeve until the load is released.' If thereafter the ring moves through a greater angle than the spacing of the ratchet teeth 38 the nut 13 is rotated to take up wear. If the brake is held applied by the hydraulic means while the hand lever is released the nut is held against rotation, a spring 39 gripping the end of the nut is consequently stressed and will rotate the nut, when the brake is released, to effect the adjustment.

Patent GB-1193742-A (GB)
Title: Safety Interlocks for Cameras with Removable Magazines and Interchangeable Objectives
IPC: G03B17/42
Filed: 1968-02-13
Abstract: 1,193,742. Cameras with inter-changeable lenses. KONICA CAMERA CORP. Feb.13, 1968 [Feb. 24, 1967], No.7154/68. Heading G2A. In a camera having inter-changeable lenses, and also a removable magazine which itself has a removable sliding light shield, the said shield has a flange which can engage and actuate locking means for preventing the shutter release from operating, and also for preventing removal of the lens. As shown, the shutter release member 2 has a notch 6 in which the end 8 of a sliding bar 7 can engage, so preventing the release from being operated. The other end of bar 7 is normally biased by a leaf spring 9 away from notch 6. Fixed to this end of bar 7 is a rearwardly-extending bar 10, which has a downwardly-extending lug 30 with an inclined end 32 (seen more clearly in Fig. 4 not shown). The mounting ring 3 for the lens has an integral arm 14, and is normally held against rotation by a detent plate 15 urged into engagement with arm 14 by a leaf spring 17. Plate 15 is carried by a rocking bar 16 pivotable about a vertical axis 18. Bar 16 also has an inclined lug portion 31, 33 (see also Fig. 5 not shown) similar to lug 30, 32. Two rotatable members 22, 23, pivoted to the camera body, can rotate into or out of engagement with lugs 32, 33, and are joined by a vertical link bar 24. The lower member 23 has a toothed part 29 which meshes with a rack 26. This is pulled rearwardly (when no magazine is present) by a spring 25. In this position, members 22, 23 are both rotated clockwise, engaging with lugs 32, 33. At the upper end, this slides bar 7 to the right, engaging and locking the release 2 against movement. At the lower end, bar 16 (and hence plate 15) is pivoted out of engagement with arm 14. Thus when no magazine is present, the release is locked, and the lens can be detached. When the magazine together with the sliding shield is introduced, rack 26 is pushed forward against the spring, so rotating and disengaging members 22, 23 from inclined lugs 32, 33. However the flange 12 on the sliding shield still holds both bars 7 and 16 against movement, so that the shutter release is still locked, and inter-change of lenses permitted. But when the sliding shield is removed from the magazine, thus uncovering the film ready for exposure, bar 7 is drawn out of engagement with notch 6 by spring 9, thus freeing the release member 2 for operation. At the same time, bar 16 is freed to pivot, urged by spring 17, so that detent plate 15 latches round arm 14 and thus prevents removal of the lens mount.

Title: Improvements in combing machines
IPC: D01G19/10
Filed: 1921-03-07
Abstract: 177,967. Nasmith, J. W. March 7,1921. Combing machines. -In a cotton-combing machine provided with a feed-device of the kind described in Specification 138,958 means is provided to couple each feed-roller in the machine to a common rock shaft and to limit and to vary the extent of the oscillation of the shaft and thereby to provide and to adjust the extent of the movement of the feed-rollers on the nipper plates. Means is also provided to adjust simultaneously the position of the feedrollers on the nipper plates without affecting the amount of the feed. In a machine of the kind described in Specification 132,987, the feed-roller F is carried in bearings 30 adjustable along a rod 31 which is connected to a bell-crank lever L pivoted on the pin 16 connecting the operating link 17 to the nipper frame N2. The lever L is connected to a rock shaft T3 carrying a lever 36 on the boss of which is mounted a plate 37 with ears 38, 41, the latter carrying a screw s, adapted as the plate rocks with the shaft T3 to contact with a fixed piece 39. The lever and plate are adjustably connected by a bolt 43 passing through a slot 42. As the nipper frame rocks on its pivot N, the shaft T3 is rocked until the ear 38 or the screw s contacts with the stop 39. The continued movement of the nipper frame then causes the feed-roller to move along the nipper plate P2. Adjustment of the screw s varies the extent of this movement. Adjustment of the plate 37 relatively to the lever 36 varies the position of the feed-roller on the nipper plate. The feed-roller is pressed on to the plate P2 by a spring lever 45. A ratchet arrangement is provided as described in Specification 138,958 to prevent rotation of the feed roller as it is moved forward over the nipper plate during its feeding action.
