Filed: 1923-06-20
Abstract: 217,424. Linotype & Machinery, Ltd., and Jakeman, J. W. June 20, 1923. Delivery apparatus.-In sheet-delivery mechanism comprising endless chains with grippers mounted on shafts carried in brackets attached to the chains, the lack of rigidity of the brackets is overcome by providing abutments thereon adapted, at certain periods of the travel of the chains. to engage links of the chains other than those to which the brackets are attached. In the construction shown in Fig. 1, the shaft 1 of the gripper 3 and the shaft 2 of the coacting pad 4 are carried by brackets 10 attached bv rivets 11 to a pair of links of the chains 7, the brackets 10 having extensions formed with abutments 12 adapted to contact with abutments 13, on plates 14 attached to other links of the chains, so as to support the brackets rigidly at the time they are passing round the sprockets 8. In the construction shown in Fig. 2, additional abutments 16. on arms 15 of the brackets 10, coact with other chain abutments 17 to support the brackets when on the horizontal runs. In the modification shown in Fig. 3, lengthened chain pins 19 engage slots 18 in the brackets 10, the pins providing rigid support by contacting with the upper ends of the slots when the chains are straight and with the lower ends of the slots when the chains are passing round the sprockets.

Title: Automatic alternating current arc welding device
IPC: B23K9/073
Filed: 1951-07-06
Abstract: 682,938. Automatic arc electrode feed systems. AKT.-GES. BROWN, BOVERI, & CIE. July 6, 1951 [July 8, 1950], No. 16125/51. Class 38 (iv). In a Ward-Leonard automatic electrode feed for an A.C. arc, wherein the generatordifferential-field-winding is energized by the rectified arc voltage and an opposing reference voltage from a generator 11, automatic starting is provided by relays 13, 14 which operate just below the minimum and just above the maximum working arc voltage respectively. Before the arc ignites both relays are operated by the no-load voltage of the welding transformer to disconnect the rectifier 10 and generator 11. Thus the electrode is advanced by action of the reference field 8. When the arc strikes, short-circuiting the transformer both relays drop out and the opposing voltage from generator 11 is applied through resistance 12 to differential field to withdraw the electrode, until the arc voltage rises and relay 13 operates disconnecting resistance 12, and normal automatic control takes place. Additional contacts may be operated by relay 14 (i) to insert a resistance 16 in the reference field 8 to reduce the electrode advance speed during striking, and (ii) to insert an " economy " resistance 18 the coil of the low-voltage relay 13 to prevent overloading by the open-circuit voltage.

Abstract: 615,261. Door locks. INGERSOLL, Ltd., YOUNG, L. W., and TAYLOR, J. W. June 5, 1946, No. 17091. [Class 44] A lock comprises a casing 1, a slidable bevelled spring bolt 3 having a spring 4, a dead bolt 6, slidable in the casing and interconnected with the spring bolt 3 by an operating cam 8 so as to be shot automatically when the door is closed (as shown) and a door handle inside and a key-operated mechanism outside for withdrawing the dead bolt. The operating cam 8 acts on the dead-bolt through faces 21 and 14, the latter being provided with a series of steps for engagement with the nose 13 of the cam to prevent forcing back of the dead-bolt. When the door is opened, the end 9 of the spring bolt engages the part 10 of the cam and maintains the dead-bolt withdrawn, the spring 4 being stronger than the spring 7. The cam 8 may be operated by a key from the outside or by an inside handle having a part 19 acting through the lever 15. A locking cam 22 coaxial with the cam 8 is movable by reverse rotation of the key to a position as shown in which it abuts a part 24 of the bolt and prevents its withdrawal by the inside handle. A fingeroperated cam 25 may be moved to block the operating cam 8 and retain the dead-bolt in its withdrawn position.
