Title: Tower cranes
IPC: B66C13/54
Filed: 1973-02-19
Abstract: 1411177 Cab elevator for cranes POTAIN 19 Feb 1973 [16 Feb 1972] 7959/73 Heading B8H The control cab 10 of a crane is raisable between the ground and an operating position to save the operator the climb up a mast 1. The cab is suspended by cables 12 from a parallelogram linkage 4 pivoted to a cab mast 2 mounted on the mast 1. The cables form double run tackles about pulleys 11 at each side across the width of the cab 10 and are wound on a drum (18), Fig. 8 (not shown). A safety cable 6 secured to the centre of the cab passes around a spring biased pulley 13 and is wound on a drum (19). The cable 6 may include a central cable (14), Fig. 6 (not shown), or a separate control cable may be connected to the cab and be wound on a further pulley (19). In use, the cab is raised by the cables 12 until it engages with the linkage 4 and locked thereto by a locking device 8. Further movement of the cables 12 moves the linkage 4 and the cab in an arc towards the mast until the linkage is locked to the cab mast 2 by a locking device 9. A crane control cable can then be connected to the cab. To lower the cab the above procedure is reversed. The drums (18), (19) of the cables 12 and 6 are driven by an electric motor (16) through a reduction gear-box (17). The drum (18) is coupled direct to the output shaft 22 of the gear-box, whilst the drum (19) is connected by way of a one-way drive (23) and a spring biased friction clutch (25). The drum 19 is slightly greater than half the diameter of the drum 18, due to the cable 6 having a single run tackle compared with the double run tackles of the cables 12, with any speed differential between the drums being accommodated by the friction clutch. Mounted on the end of the drum (19) remote from the drum (18) are a pair of spring biasedpawls (31), Fig. 9 (not shown), which move outwardly under excessive drum rotation, through failure of the cables 12, to engage in housing (29) and stop rotation of the drums and movement of the cab. The spring biased pulley 13 accommodates the initial braking forces.

Title: Improvements in and relating to fluid pressure gauges
IPC: G01L7/16
Filed: 1949-03-25
Abstract: 668,910. Pneumatic-tyre pressure gauges. TURNER, W., and ASKEW, G. March 23, 1950 [March 25, 1949], No. 8218/49. Class 106 (ii). In a fluid-pressure gauge of the kind in which fluid pressure from an inflated body moves a piston 8 in a cylinder 7 against the action of a spring 16 to move axially a graduated indicating member 9 which is wholly enclosed in a casing 2 closed by a head 3, the indicator is retained in indicating position after the fluid-pressure is cut off by a transverse pull applied by a spring-urged member slidably mounted in the casing while permitting axial movement of the indicator under pressure with manipulable means for effecting its release. The head 3 incorporates a resilient seating and sealing ring 4 for the tyre valve and a valve unseating pin 5 with a passage 6 communicating with the cylinder 7 and lateral and axial ports 26, 27 through which fluid pressure passes. To move the indicator under pressure a head 15 on a piston-rod 14 engages the upper of two discs 12, 13 supporting the semi-cylindrical graduated indicator 9 and to retain the indicator the discs 12, 13 are linked by a rod or wire 19 which is engaged by a hook 20 attached to a cup 21 pressed outwardly by a spring 22 in guides 23 with stops to limit outward movement. When the cup 21 is pressed inwards the retaining means are released. The outer casing .2 is preferably formed of transparent plastic and parts may be rendered opaque by applying colouring matter or by inserting a thin sleeve.

Passages 15, 16 connect the ends of the valve chamber with the ports 13, 14 and are always open to a restricted exhaust through grooves 19, 20. In the position of the parts shown, fluid passes from the inlet 8 to the lefthand end of the cylinder 2. Fluid is exhausbing through the outlet 12. Live fluid passes from port 10 through port 18 and acts with reduced pressure on the left-hand-end collar of the valve. The forward cylinder end is open to exhaust through passage 9, outlet 12, and port 14. When the piston covers port 13, the left cylinder end is open slightly to exhaust. Live fluid still entering passes through passage 15 to the right-hand end of the valve and throws the valve to the left against the reduced pressure in the left-hand end of the chest. Outlet 12 is closed and outlet 11 opened, and the main distribution is reversed. Fluid exhausts from the left-hand valve-chest end through passage 16 and live fluid passes to the right-hand ends of the chest and cylinder, and the main piston is reversed. The annular exhaust ports 19, 20 may be replaced by ports in the valve, or ports 23 in the valve-chest ends, or all three sets of ports may be used.
