Title: Internal shoe drum brakes
IPC: F16D65/22
Filed: 1972-08-01
Abstract: 1432777 Internal shoe drum brakes; wear adjustment GIRLING Ltd 25 July 1973 [1 Aug 1972] 35782/72 Heading F2E An internal shoe-drum brake of the two leading-shoe type with two shoes 2, 3 has expanders 6 with brake applying tappets 7 and an automatic adjuster 10 for each shoe, e.g. 2, which adjuster 10 comprises a housing 13 and a member 11 and a sleeve 12 is screw-threaded interengagement, the sleeve 12 being rotatable to increase the effective length of the adjuster 10, and a return spring 32 is connected between the other shoe 3 and a lug 27 on the housing 13 which spring 32 serves to retract the shoe 3 and the tappet 7 acting on the adjuster 10 but the load on the spring 32 does not increase when the length of the adjuster 10 is increased. In the embodiment illustrated each expander 6 between each pair of adjacent shoe ends incorporates a wedge 8 which is movable by fluid pressure, e.g. an air actuator 9, or by mechanical means, or both between rollers on the inner ends of the tappets 7 to separate the tappets 7. The housing 13 of each adjuster 10 comprises a transverse tongue 14 to hold the adjacent tappet 7 against rotation. The member 11 has a head 15 which is grooved to receive a pin 16 mounted between the webs 17, 18 of the shoe (e.g. 2). The sleeve 12 is provided with a ratchet ring 19 engaged by a pawl tooth 21 on a lever 22 which is angularly movable about a pin 23 fixed in housing 13. The lug 27 is formed with three aligned holes 28. A tension spring 29 extends between the middle of the three holes 23 and a lug 31 on the shoe 2 which spring 29 serves to hold the adjuster 10 in engagement with the pin 16. Two of the said return springs 32 are provided between the other two holes 28 and holes 33 in the webs of the shoe 3. For normal service braking the drum rotates in a counterclockwise direction and the trailing end of each shoe 2, 3 is acted upon by the tappet 7 of the expander 6 for that end of the shoe through the adjuster 10. In application of the brake during reverse rotation of the drum excessive movement of the shoe causes the lever 22 to move through an angle corresponding to the spacing between two or more teeth on ring 19 and, in so doing, loads a spring 25 connected between lever 22 and an anchorage 26 on the expander 6. The sleeve 12 is rotated by the lever 22 during brake release under the action of spring 25 to increase the effective length of the adjuster 10. The arrangement of springs 32 ensures that they are not stretched as the length of the adjuster 10 increases to compensate for wear of the friction lining.

Title: Improvements in or relating to moulding machines
IPC: B29C43/00
Filed: 1935-12-28
Abstract: 467,922. Moulding and packing plastic material. KUSTNER FRERES & CIE SOC. ANON. Dec. 28, 1935, No. 35925. Convention date, Dec. 29, 1934. [Class 87 (ii)] Plastic material is moulded into pieces of equal size and packed by a machine comprising a device for feeding the mass into a mould and mechanism, controlled by the mass fed into the mould, for displacing the mould, stopping the feeding device, discharging the moulded piece and packing it, the restarting of the feeding device being effected at the end of the packing operation. One method of performing the moulding operation is shown in Fig. 1, in which the plastic mass is forced into the mould 13 by a worm 8 which is driven by a shaft 9 from a box 10 containing cams and clutches to connect it to a motor 11. The mass forces back the piston 15 until the piston rod 16 contacts with the screw 17 and rocks the lever 18 thus starting the toothed wheel 22 which withdraws the mould 13 to the ejecting position 23. A projection 24 meets a pin 25 to stop the wheel 22 and to operate a lever 27 which ejects the moulded slab by means of the plunger 15. During ejection the worm 8 stops working. The weight of material moulded can be varied by adjusting the screw 17. In Fig. 2, two moulds are located in a rotary disc 39. The filling of the mould 40 by the worms 38 raises the lever 41 which starts the toothed wheel 42. This wheel rotates the disc 39 and also an adjustable cam 44 thereon actuates a lever 45 to declutch the worms 38 from the driving shaft 36. Another cam on the wheel 42 actuates a lever 46 which ejects the moulded slab from the mould 43 onto wrapping paper on a table 47 whence it is pushed to the position 51. A pusher 52 then pushes the article into a wrapping mechanism 53 of known type. A further movement of the pusher 52 ejects the wrapped piece and at the same time the lever 45 returns to its initial position and the moulding operations recommence. As shown in Fig. 3, the piston rod 56 and the adjusting screw 57 are tapered so that when the mould begins to move the rod 56 escapes from the screw and contacts with the surface 59 which determines the exact filling of the mould. A device for printing a design &c. on the moulded piece may also be provided and a wire cutter for separating the piece from the ejecting piston.

The rotor of a tachometer generator has a continuous peripheral surface carrying an uninterrupted circumferential bounding layer of non-magnetic conducting material acting as a screen, and fits closely in a continuous stator bore which acts as a supporting journal bearing for the armature. The stator consists of a block of metal 11 having a bore 12 forming poles 34, 35 separated by grooves filled with copper rods 37 so as to leave only saturated bridges 36. The poles are energized by magnets 41, 42 and the whole stator is located in a casing 23 by radial brass spiders 24 brazed to the sides of the block. A laminated selsyn stator 27 having four-pole A.C. field coils is secured at the end of the stator. The cavities are filled with an insulating resin which helps to secure the parts together. The stator 27 is of larger bore than that of the main machine so that it does not act as a bearing surface, but a bearing surface at the driving end is provided by a flange 31 bored to the same diameter as the stator. The rotor is made by broaching out a channel in a cylindrical billet 43 to house the coil 56 with its former 57 and a magnetic core 61, non-magnetic end pieces 44, 46 being brazed on. The poles are separated by milled slots 52 filled with brass, and the combined cylindrical surface is silver plated to form a uniform bearing surface which also serves to screen the rotor against stray fields. The narrow part 47 of the rotor carries the laminated rotor part 63 of the selsyn machine, and also a driving boss 64 which has a cylindrical bearing surface 65 engaging the stator surface 31. A central part 67 of the rotor is turned down to receive lubricating oil. The rotor may be fabricated.
