Abstract: 1,126,727. Safety devices for jib-cranes. GROVE MFG. CO. 12 July, 1967 [21 July, 1966], No. 32175/67. Heading B8B. A safe load control device for a telescopic boom, comprised of a base-section 1, a midsection 2 and a fly-section 3, pivoted at 6 to a pair of supports 7 comprises an hydraulic pressure switch 19 with a fluid pressure input from fluid motors 10, 11 for luffing the boom and a mechanical input through a linkage 40 sensing the elevation of the boom through tilting of the fluid motors 10, 11. The switch 19 receives the fluid pressure through a line 39 and acts through a piston-rod 24 to close a microswitch 34 against the action of a compression spring 29 the loading of which is varied by the linkage 40 in accordance with the elevation attitude of the boom. There is thus a differential action in the switch 19 between boom elevation information through the linkage 40 and load information through the pressure in the fluid motors 10, 11. The microswitch 34 when closed operates a warning light and an audio alarm and, through a combined electrical-hydraulic circuit, Fig. 6 (not shown), prevents the operation of any of the controls for the apparatus except in the direction to reduce the overload.

Title: Improvements in centrifugal apparatus for separating and collecting dust or other solid particles from air and gases
IPC: B04C5/18
Filed: 1933-11-20
Abstract: 429,028. Centrifugal dust separators. CHELTNAM, C. H. W., and CHELTNAM, C. H., 188, Adelaide Road, Brockley, London. Nov. 20, 1933, No. 32287. [Class 23] A separator of the cyclone type has means for modifying the direction or velocity of the gas in the dust eduction pipe so as to modify the size of the dust particles precipitated therein. A separator 1, of the type described in Specification 406,036, is shown in Fig. 1 with an exhauster 4 connected to the clean gas outlet 3. The dust eduction pipe 5 is connected to a hopper or dust container 6, the ingress and egress of the dust being controlled by slide valves 7, 8. A small bore pipe 9 allows gas to be withdrawn from the pipe 5 or to be added from an outside source. Where gas is to be withdrawn the inner end of pipe 9 terminates in a funnel 10, and it may terminate in a small dome on the top of the dust container. Where gas is to be added the pipe 9 conveys it to a chamber 12 round the pipe 5 from which it passes into the pipe 5 through slots 13. Two separators may be connected in series and gas may be added in the eduction pipe of the first while gas is withdrawn from the eduction pipe of the second. The valves controlling the entry and discharge of each dust container may be of the form shown in Fig. 9. The plate 24 has a circular port and slides between two castings 25, 26 which are provided with packing rings 27 to establish air-tight joints. The castings are held together by springs but can be forced apart by cams 33, 34 operated by a hand lever 36. In a modification, blade springs are used to ease the seatings off the slide while cams are used to provide the clamping pressure. A linkage 50 is employed in the form shown in Fig. 1 to ensure that the entry and discharge valves 7, 8 shall not both be open at the same time.

Title: Control for change-speed gears
IPC: F16D48/02
Filed: 1959-09-24
Abstract: 880,128. Change-speed control; clutches. HURTH, H., HURTH, F., and HURTH, L. Sept. 24, 1959 [Oct. 18, 1958], No. 32483/59. Class 80 (2). Change-speed gearing includes a two-speed constant-mesh gear having the ratios introduced by hydraulically engaged friction clutches 18, 20 under the control of a distributing valve 41, the low ratio clutch 28 being formed as an over-running clutch, and the valve 41 in an intermediate position supplying liquid to engage both clutches so there is no interruption of drive during change from low to high gear. Constant-mesh gear.-A gear 12 is fast on a driving shaft 10 and meshes a gear 25 on an intermediate shaft 24 clutchable to a gear 26 fast on an output shaft by the clutch 28. Gear 26 meshes a gear 13 connectable to the input shaft by the clutch 18. A second constant mesh gear may be in series with the first as shown in dotted lines in Fig. 1. Clutches.-The clutches are of the multi-disc type and are engaged by hydraulic pressure in a chamber 21 or 37 of a moving cylinder 20 or 36 co-operating with a stationary piston formed on the input shaft of the clutch. The clutches are disengaged by springs 22, 38. Clutch 28 has plates 30 splined to a casing 29 fast with the gear 26 and plates 31 splined to a sleeve 32 having a reversible screw-threaded connection with the intermediate shaft 24. The sleeve 32 is spring-loaded to the left so that the clutch can be engaged by hydraulic pressure, but when the clutch 18 is engaged the sleeve screws along the intermediate shaft so that the clutch 28 disengages. Control.-Hydraulic pressure is provided by a pump 51 supplying liquid through a solenoidoperated pilot valve 48 to the valve 41 loaded by a spring 43 to the position shown in which liquid is supplied to the chamber 37 to engage clutch 28 for low gear. A pilot valve 60 is actuable by a solenoid to a position in which liquid is supplied through an adjustable throttle 54 to a valve chamber 73 to move the valve spool to its uppermost position in which chamber 21 is pressurized to engage clutch 18 and chamber 37 is exhausted to disengage clutch 28. During movement of the valve spool between its end positions both chambers 21, 37 are open to pressure so that both clutches are engaged and clutch 28 over-runs. A switch 70 is closed to actuate the pilot valve 48 and switches 70, 71 are closed to actuate the valve 60. If the equipment being driven is stopped, e.g. due to current failure, with the control switches 70, 71 left in the high gear position, the valve 41 will be moved to its lowest position since the pump 51 is stopped; on restarting, the valve 41 will remain in this position until the pressure has built up sufficiently to actuate the valve 41. Low gear is thus engaged initially so that the engine is unlikely to stall. In a modification the pilot valves are controlled by a cam.

Title: An improved coupling device
IPC: A44C5/20
Filed: 1949-12-20
Abstract: 668,899. Couplings for vehicles. MODREY, H. J. Dec. 20, 1949 [Dec. 21, 1948], No 32621/49. Class 103(v) [Also in Groups XXV and XXVIII] A coupling device, e.g. for joining two chains 12, 13, Fig. 1, comprises a female member 10 having an opening 16 to receive the enlarged head 18 of a clamping rod 17 on a male member 11, a sliding wedge 20 mounted alongside the rod 17, being spring urged to pass into the opening 16 when the head 18 has passed through to secure the head in the connected position. The male member consists of a sleeve 25 having flanged ends 26, 28 retaining a slidable guide member 22 at one end and a washer 29 at the other. The clamping rod is formed with an abutment 17<SP>1</SP> engaging the washer 29 adn a loop 19 for the attachment of the chain. In connecting the parts together, the head 18 is inserted into the opening 16, a part of the bridge 15 adjacent thereto pressing back the wedge 20. Since in this position the members 10 and 11 arc out of alignment, closing movement causes the guide 22 to be driven in against the spring 31. When the head 18 has passed through the opening 16 the members 10 and 11 are allowed to be coaxial so that the guide 22 may pass out into the bridge 15 and the wedge 20 into the opening 16 alongside the rod 17 which is thereby substantially filled. The members are disconnected by drawing the sleeve 25 away from the member 10, this movement being transmitted by a lug 21 to the wedge which is thereby withdrawn from the opening 16, allowing the head 18 to pass out and the members to separate. In a modification, Fig. 4, the loop 19 of the clamping rod is enclosed by the cupped end of the sleeve 25, the chain 13 passing through a slot 35 affording the necessary relative movement. In another form,'Fig. 7, the members 10, 11 are of flat rectangular section, the clamping member 36 being formed from strip material and having a head 37, shoulders 52 and a chain loop 51. The wedge 40 has a part 42 entering the opening 16 and is loaded by a spring 45 located in a slot 46 in the clamping member 36. The method of operation is similar to that described above. Withdrawal of the wedge is effected by a flange 43 on the housing 39 entering the lug 44 on the wedge. The end of the clamping member may again be enclosed in the housing, the loop 51 being accessible through a slot. The fastening members of this form may be riveted to the flat members, e.g. of a box which are thereby secured together. In the form of Fig. 9, the chain 13 is connected to an eyelet 62 riveted to the sleeve 60 of the member 11 so that the parts are automatically disconnected when the tension of the chain exceeds that of the spring 31. Specification 605,434 is referred to.
