[Class 114] In boat-propulsion gear wherein the propeller shaft is actuated by manual gear, a casing is provided to carry the bearings for the final bevel pinion drive and the forward and reverse pawl gear thereof, and it is further provided with a removable cover plate opposite the propeller shaft for the attachment of a power drive. A propeller shaft 23 is coupled by a universal joint with a bevel wheel 31 which meshes with the bevel wheel 24 freely mounted upon a transverse shaft 18, the bearing for the shaft and the bevel wheel being carried by a casing 21. The shaft 18 is adapted to be operated by cranks 16 from a number of fore and aft rods which are oscillated by hand levers and when manual propulsion is desired the lever 28 puts the clutch 26, which is keyed on the shaft 18, into engagement with the bevel wheel 24. Upon the shaft is a pawl wheel 34 with which engages ratchets 35 or 36 according to the direction of rotation required. In the hub 25 of the wheel 24 there is a one-way ratchet 27 which functions when the hand-propulsion gear is used for starting up the power machine. On the end cover 38 being removed, a gear-box 41 may be attached and the drive therefrom connected by the bevel wheel 39 with the crown wheel 24. The various control rods 42, 43 of the power plant are led through passages in the casing to the after control cockpit of the boat. Specification 489,624 is referred to.

    • 551,343. Launching rafts &c. FLEMING, I. R., and FLEMING, F. E. Aug. 16, 1941, No. 10436. [Class 115] Gear for launching a life-saving raft, lifeboat, cargo, or the like from the deck of a ship comprises a parbuckle device extending from the deck D and around the raft 11 to control the movement of the raft down a slipway 10 and to form a cradle for the raft as it moves over the edge of the deck, and a lowering tackle which supports the raft after it has left the slipway. The latter comprises two or more articulated triangular frames which can be raised by a tackle on the davits E from a horizontal stowage position on the deck to an inclined launching position, the outer frames having eyes 30 for releasable engagement by pivoted hooks 29 on the ends of the raft. The lowering tackle comprises slings 12 and falls 13 attached to triangular sling plates 14 on the heads of the davits, the plates 14 also carrying falls 18 for the usual lifeboat 19. The parbuckle device comprises a block and tackle 21 connected at one end 22 to the deck D and at the other end to a sliplink 23 connected to a pair of spaced-apart ropes 24. These are attached by hooks 25 to eyes 26 on the inboard lower edge of the raft, and pass through eyes 27 on the edge of the deck which prevent the passage of abutments 28 on the ropes and so automatically release the ropes from the raft when the latter moves off the slipway and attach them to the deck.
