Title: Telescopic crane jib
IPC: B66C23/693
Filed: 1972-02-09
Abstract: 1340978 Bolt fastenings LEO GOTTWALD KG 9 Feb 1972 [13 Feb 1971] 6092/72 Heading E2A [Also in Division B8] A crane jib comprises a housing 1 and three telescopic parts 2, 3, 4 and has short peak outriggers 5, 6. A single acting hydraulic cylinder 8 is fixed rigidly at its bottom to the lowest telescopic part 2. Piston rod 7 of the cylinder 8 is fixed at its lower end to the bottom of the housing 1. The parts 2, 3, 4 are all of the same length which is less than half the length of the housing 1. For extension the jib is brought to the vertical position by a head-stay cable 25 and locked there by a telescopic rod 26. Liquid is exhausted from the cylinder 8 so that the parts 2, 3, 4 all move downwards leaving the peak outriggers 5, 6 suspended from the upper end of the housing 1. When the parts 2, 3, 4 reach their lower limit outrigger foot 15 is locked to the upper end of part 4. The piston 7 is now extended from the cylinder 8 lifting the parts 2, 3, 4 and the outriggers 5, 6 until upper rim 16 of the part 4 moves past spring-loaded catches 17 at the upper edge of the housing 1, whereupon retracting the piston 7 and cylinder 8 leaves the part 4 suspended while the parts 2, 3 descend to the position shown in Fig. 4b. The lower end of part 4 is then locked to the upper end of part 3 and by similar cycles of extension and retraction, the parts 2 and 3 may also be extended, all the parts 2, 3, 4 being locked together end to end. The jib may also be only partly extended in various ways as desired, suitable locking devices being provided. Fig. 8 shows a two-stage locking device for locking the lower end of part 4 to the upper end of part 3. A tube 20 fixed to the lower end of part 4 contains a bolt 18 and a tube 30 fixed to the upper end of part 3 contains a bolt 19. A limit stop 31 is also fixed to the upper end of part 3. At the end of the movement when part 3 is being lowered into the housing 1 the stop 31 comes to rest on the tube 20 whereupon the bolt 18 is advanced pneumatically to the position shown. Subsequently, when part 3 is raised a supporting surface 32 (which may be the inner surfaces of the tube. 30) supports the bolt 18 whereupon the bolt 19 can be advanced pneumatically into a bore 34 of the bolt 18 with a wedging action. Fig. 10 shows how the bolt 18 at the lower end of part 3 wedgingly engages a sleeve 35 at the lower end of part 2 to lock these lower end parts together. Fig. 11 shows the parts 3 and 4 locked together at their upper ends by a nose 39 on the bolt 19 engaging an opening 37 in part 4. The nose 39 is forced into contact with wedge 38 by a pin 40 actuated by a wedge 42 advanced by an hydraulic cylinder 41. Fig. 11a shows a further locking device using two bolts 47, 48. A nose 50 of the boit 47 engages a wedge 52 in an opening 51, a piston 49 advancing bolt 48 to thrust the nose 50 firmly into engagement with the wedge 52.

Convention date, March 7, 1929. Void [Published under Sect. 91 of the Acts]. [Class 100 (i).] In a web-renewing mechanism for a printing, bag-making, or other machine, in which the new roll having paste applied thereto is pressed into engagement with the running web, means are provided to lock the new roll against rotation until the pressure between it and the running web exceeds a predetermined amount. This pressure is sufficient to ensure that the roll, when released, will be brought to the speed of the running web in one revolution. The active roll 3 and reverse rolls 4, 5 are supported at their ends on short spindles rotatably mounted in the arms 2 of a frame fixed to a shaft 1 which is rotatable by an electric motor 43 to bring the rolls in succession to feeding position. Secured to a spindle of each roll is a disc 20 provided with one or more notches 22, Fig. 5, one of which is normally engaged by a locking roller 25 on a lever 23 the opposite end of which carries a roller 26 normally engaged beneath a block 31 as shown in broken lines. The lever 23 is pivoted on a stud 24 supported by a plate 28 fixed to the arm 2 and a plate 27 secured by screws 29, 30 to the plate 28, and a spring 38 urges the lever 23 to looking position. The block 31 is fixed to a rod 32 slidable in guides 34, 33 and provided with operating knobs 36, 37 at its ends and with a spring 35 bearing against the guide 33 and a nut 41 by which the pressure of the spring can be adjusted. When the roll 3 is nearly exhausted, the roll frame is turned to bring the roll 4 into contact with the expiring web 18 and the movement is continued until the pressure of the roll on the web is sufficiently great for the disc 20 to force the roller 25 out of the notch 22 against the pressure of the spring 35. The roll then rotates to bring the pasted area thereon into engagement with the web 18, the roll being initially positioned so as to make substantially a full revolution before adhesion takes place. When the roller 25 is forced out of the notch 22, the roller 26 moves from beneath the block 31 into contact with a bevelled surface 39 thereon which holds the lever in an inoperative position until the rod 32 is lifted by hand to allow the spring 38 to restore the lever to locking position. Endless belts 6, either stationary or driven by connections to the press or other source of power, may be provided in engagement with the running roll to control or facilitate the unwinding of the web.
