Abstract: 977,714. Ratchet clutches. S.S.S. PATENTS Ltd. March 5, 1962 [March 13, 1961], No. 9181/61. Heading F2C. In a synchronous self-shifting clutch in which axial helical movement of an inter mediate sleeve is initiated by pawl-and-ratchet mechanism, the intermediate sleeve is formed with rings of clutch teeth at its ends which are engaged with corresponding teeth on the driving and driven shafts to establish the drive, the intermediate sleeve being supported, when disengaged, principally at two axially spaced zones, a further zone taking over the supporting function from one of the former when the sleeve is engaged, to enable the sleeve to accommodate slight misalignment of the shafts when the clutch is engaged. As shown in Fig. 1 the shafts 1, 3 carry hubs 2, 5 with rings of teeth 7, 8, while the intermediate sleeve 9 has corresponding end rings of teeth 10, 11 and is connected to hub 2 by helical splines 14. The hub 5 carries pawls 21 associated with internal ratchet teeth 20 on sleeve 9. When shaft 3 overrruns shaft 1 in the direction shown the rings of teeth are disengaged and pawls 21 overrun teeth 20, but when shaft 1 overruns in the same direction pawls 21 engage teeth 20 and sleeve 9 is moved axially by splines 14 so that teeth 7, 10 and 8, 11 are fully engaged to establish the drive. The teeth 7, 10 are wide-pitched to permit their relative helical movement during engagement and disengagement. When sleeve 9 is disengaged it is supported by the contacting areas of teeth 7, 10 and by cylindrical surfaces 18, 19 on the sleeve 9 and hub 2 respectively, and when it moves to the right to the engaged position surfaces 18, 19 separate and their supporting function is taken over by the teeth 8, 11. In the alternative arrangement of Fig. 7 the intermediate sleeve is in two portions 31, 34 and has clutch teeth 32, 37 associated with teeth 33, 38 on the shafts 24, 25 and is connected to shaft 24 by helical splines 29, 30. An auxiliary sleeve 46 connected to shaft 25 may be coupled by oppositely acting pawls 45, 48 to a second auxiliary sleeve 43 splined to a member 40 bolted to sleeve 31. When shafts 24, 25 reach synchronism sleeve 43 is moved axially against a stop 59 on member 40 to initiate movement of sleeve 31, 34 to engage teeth 32, 33 and 37, 38, the final portion of the movement being cushioned by a dashpot arrangement 55, 56. When disengaged, sleeve 31, 34 is supported by the teeth 32, 33 and a cylindrical bearing surface 51, this function of the latter being taken over by the teeth 37, 38 when the sleeve is moved to the engaged position.

Filed: 1941-07-29
Abstract: 550,456. Forging rock drills. HOLMAN BROS., Ltd., and MILLS, E. C. July 29, 1941, No. 9634. [Class 83 (iv)] The bore of work drills is opened out after forging the shank and bit ends by pneumatic means put into operation by the pressure of the drill on the punch. The drill 1 is held in a groove in a block 5, Fig. 1, shown as for the shank end, sliding on a bar bed 7 under the control of a hand lever 8 pivoted at 9 to a lug 34 on a bracket carrying the bar 7 and bolted at 33 to a support which may be the drill forging machine. Links 10 pivoted to the lever at 12 have a series of holes 13 any of which may be engaged with trunnions on the block 5. The proportions are preferably such that with the block in its most advanced position the centres of the pivots 12 and the trunnions lie in the axis of the punch 2. The punch holder has a flange 24 mounted with play in a housing 22 secured to the hammer cylinder 18. When the drill is forced on to the punch by the lever 8 the collar 24 is forced against a bushing 21 and the cylinder is pushed back causing the valve 16 to be cammed open, by the surface 25 of a fixed spool like member 26, and putting the hammer into action. When the hole has been opened up to the required amount the lever 8 is pulled back drawing the flange 24 against the front end of the housing and again causing actuation of the hammer when the surface 27 opens the valve. In this position the whole apparatus is vibrated and withdrawal of the punch is facilitated. For opening the bit end a block 6, Fig. 3. is substituted for the block 5. In a modification a double sided block is used one side serving for each end of the drill. The block has two sets of trunnions and is rotated about the bar 7 to engage the required set with the links 10 which have notches between them the notches being closed by a spring plate locked in position by a spring pin. The punch 2 is reduced in a diameter about 3 inches from the point to prevent the end of the drill from shrinking on to it.
