Filed: 1923-03-05
Abstract: 216,596. Armstrong, Whitworth, & Co., Ltd., Sir W. G., Chicken, G. P., and Irving, B. March 5, 1923. Hand-gear; starting-gear. - In a convertible hand and power gear for controlling the valve-gear of an engine, the steam-power cylinder 10 is connected to an oil cataract cylinder 160 the piston of which is secured to the reversing-rod 19. The cylinder 160 has spring-pressed lift valves 21, 22 arranged in chambers communicating with the cylinder ends and which are engaged by double-ended levers 26, 27 mounted on an eccentric pin 250 on a shaft 25 connected to a hand-lever 28 mounted on the side of the hand gear. The levers 26, 27 abut fulcrum stops 261, and are raised to permit a circulation of oil in the cylinder 160 and to determine the piston speed. Leakage is made good from a reservoir 34 by a plunger 31 which is drawn out by a hand lever 32 and gradually forced in by a spring, oil passing a non-return valve to the cylinder until the lever creeps to the position shown. The piston and rod are packed by cupleathers acted on by cup-shaped annular springs held in position by rings 200. To move the gear, a lever 14 mounted on a bracket secured to the side of the hand gear and held in a central position by a spring stop, is moved to operate the valve of the cylinder 10 and the lever 28 is then operated to permit the desired motion after which the piston 16 is locked by closing valves 21, 22 and the lever 14 brought to its central position. The reversing-gear may be hand-operated by a screwed spindle 37 engaging a guided rectangular bar 39 secured to the rod 19 by a removable pin and which carries a notched disc 43 and locking-pawl 42 adjacent the wheel 38.

A reversible tooth for earth digging equipment comprises a tooth 11 secured to the surface 18 of a step cut on the cutter body 13 by a coach bolt 57. The shank of the tooth is slotted to take the square under the head of the bolt and has three further keyways 41, 41, 42 which engage corresponding keys 21, 21, 22 on the cutter body. The key 22 is rectangular with vertical sides and the keys 21 have sloping sides. of which that one 52, nearer to the cutter tip makes an angle of 15 degrees with the surface 18 and the other face 51 makes an angle of 45 degrees. When the cutter is clamped in position it is engaged by the faces 17 and 18 as well as by the keys. To reverse the cutter the nut 58 is slackened until the keys can be disengaged from the keyways and the cutter may then be withdrawn. In a modification (Fig. 5) the keys 21 and 22 are replaced by keys 61 and 62 projecting into the slot 34. The upper and lower surfaces of the tooth and the stop on the cutter body may be knurled. In a second modification (Fig. 8 there are no keys but the slot is retained and the tooth 72 is tapered. The stop 76 in the cutter body is formed at the same angle so that the tooth is located by the face 76, the wall 74 and the square 56 under the head of the coach bolt 57. Figs 10-12 (not shown) illustrate a tooth which employs the same method of clamping but in which the cutting edge of the tooth is suitably shaped for a trenching machine. In a third modification (Fig. 15) the tongues formed by the slot 34b fit into grooves 99 machined in the cutter body 13c and are gripped by resilient inserts 97. To enable the tooth to be driven out it may have projections 90 or the slot 34 b may be extended to enable a drift to be inserted. In a fourth modification (Figs. 19 and 23) the tongues 133 on the tooth, formed by the slot 129 decrease in thickness towards the slot and fit correspondingly tapered grooves 111a and 111b in the cutter body. A resilient insert 123 is contained in the central web 112 and is deformed by the inside surfaces 136 of the tongues as the tooth is inserted.
