Abstract: 514,609. Air break switches. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 5, 1938, No. 3709. Void. Convention date, Feb. 6, 1937. [Class 38 (v)] An air-break switch, which may have a gas blast supplied from a tank in a truck 16 through fixed insulator 6 to the fixed contact 15 in hood 17, has an angularly-movable insulator 7 connected to the movable contact 5 through an operating mechanism allowing the contact 5 to travel faster than the insulator-head at least in the vicinity of the fixed contact. Contact 5 is arranged on a lever 3. which is pivoted at 11 to an arm 1 so as to form a kind of toggle, and is pivoted at 10 to a lever 2 pivoted at 12 to insulator 7. Also pivoted to 7 is a link 4 pivoted to arm 1, the latter pivot point and the position of point 10 together determining the relative speeds of 5 and 7, in the example shown, two to one. The arrangement also provides for a substantially straight-line movement of contact 15 particularly in the vicinity of the contact 15, and the arrangement of pivots 10, 11, and contact point 14 in a triangle prevents obstruction by ice. The effect of ice formations on the pivot can be reduced by making them small. Members 2, 4 may have a common pivot on insulator 7. In a modification, Fig. 2 (not shown), lever 2 is replaced by a member which is fixed to insulator 7 and is pins and slot connected at the end to lever 3.

Filed: 1925-02-10
Abstract: 249,638. Dijk, H. N. van, and Mc- Laren, H. Feb. 10, 1925. Multiple-furrow ploughs; disc-tool implements; travelling gear; lifting-devices, power; reversing at headlands.-An implement for ploughing or forming furrows or trenches is provided with a draught beam connected to the implement frame and to a lever for raising and lowering the frame in such a way that it normally transmits the pull of the hauling rope to the frame for hauling the implement but may be allowed to move forward under the pull to operate the lifting-lever, the arrangement being such that when the return rope becomes operative the draught beam slides back into its original position and then turns the steering wheel into position for turning the implement. The plough may be mounted on a steering-wheel 2 and a sled 4 as described in Specification 249,637, the rear end of the sled being pivoted on spindles 6 carried by crank arms 7 on a cross shaft 8 adapted to be rocked to raise the frame 1 by means of a lever 10. A catch lever 12 engages with a notched segment 11 to hold the frame in position. Travelling wheels may be removably mounted on the spindles 6 or substituted for the sled 4. The draught beam 14 is pivoted on a pin 17 mounted in a carriage 20 movable between stops 23, 24 but normally locked in the position shown by a pivoted catch 25. The pin 17 is adjustably connected to a slotted rod 18 in the slot of which engages a pin 19 on the lever 10. When the frame 1 is to be raised the catch 25 is moved by means of a bellcrank lever 27, link 30, and hand-lever 31, and the carriage 20 and beam 14 are pulled forward by the hauling rope 15. The forward end of the beam 14 is connected to the turntable 3 of the steering wheel 2 by a chain 33. When the return rope becomes operative it turns the beam 14 until the chain 33 is taut and then pulls the beam back until its pivot is in its original position, the pin 19 moving in the slot of the rod 18. The continued pull of the rope then pulls the beam further round and thus turns the turntable 3 and wheel 2, the implement being finally pulled round. The frame 1 falls freely vhen the catch lever 12 is disengaged from the sector 11, the depth of work being regulated by adjusting the effective length of the rod 18.
