Title: Typewriter Back-Spacing Mechanism
IPC: B41J19/58
Filed: 1966-05-20
Abstract: 1,153,521. Typewriters. OLYMPIA WERKE A.G. 20 May, 1966 [21 May, 1965], No. 22458/66. Heading B6F. A typewriter having a proportional letterspacing escapement mechanism, which includes three pawls 4 1 , 4 2 , 4 3 , is provided with a backspacing operating lever 41 which through the intermediary of a rocker 36 actuates selectively arms 35<SP>111</SP> or lugs 35<SP>11</SP> on coupling levers 35, associated with the pawls, to drive one of the pawls in the carriage back-spacing direction and another pawl in the letter-spacing direction after initial disengagement of the pawls from an escapement rack 1 and to re-engage the other pawl with the escapement rack at the end of the back-spacing operation. Depression of a back-spacing key (not shown) displaces a push rod 41 away from its abutting surface 50<SP>1</SP>, so as to rock an arm 37 of a backspacing rocker 36 which lifts a bail 36<SP>1</SP> and allows pawl coupling levers 35 1 , 35 2 , 35 3  to pivot under the bias of springs 42 1 , 42 2 , 43 3 , about a pin 43 and to abut the pawls 4 1 , 4 2 , 4 3 . Displacement of the push rod 41 also causes displacement of the pin 43, mounted in a rocker 52, from its abutment surface 50<SP>11</SP> so that the pivoting coupling levers 35 1  and 35 2  engage lower steps 44 1 , 44 2  in their respective pawls 4 1 , 4 2  and the coupling lever 35 3  engages the upper step 45 in the pawl 4 3  in consequence of which lugs 35<SP>11</SP> 1  and 35<SP>11</SP> 2  or the associated coupling levers 35 1 , 35 2  are disposed in front of driving bail 36<SP>11</SP> of rocker 36 and the coupling lever 35 3  has its nose 35<SP>111</SP> 3  disposed in front of a driving bail 36<SP>111</SP> on the rocker 36. Continued anticlockwise rotation of the rocker 36 causes the coupling lever 35 1  to displace the pawl 4 1  by one tooth gap and effect back-spacing of the carriage with concomitant displacement of coupling lever 35 3  to the left. The latter pivots the pawl 4 3  whose slot edge 6<SP>1</SP> 3  abuts a pin 7, to disengage it from the rack tooth 3<SP>1</SP> and then to re-engage it with rack tooth 3<SP>11</SP> so as to hold the carriage in its back-spaced position. On release of the backspacing key the push rod 41 and rocker 36 are restored and the bail 36<SP>1</SP> disengages the coupling levers from the pawls.

Pivoted to the back of the masking disc a at j is a lever m pivotally suspended from which at q<1> is a quadrant plate q the notched radial sides of which coact with projections r, s on the dial b to rock it to its two positions determined by a stop e thereon, the movement of the dial b being limited by the recesses f in the top slot c, Fig. 1. Pivoted to the lever mat p is a lever o to one end of which is connected a spring y, anchored at z, which biasses the lever o against a stop m<1> on lever m and forces the quadrant downwards. A cam or projection w on the hour-hand spindle x engages the lever o and through it lifts lever m and the quadrant. The quadrant has projections v coacting with a biassing spring t secured to lever m, such that when lifted from the position shown in Fig. 2, the quadrant rides idly past the projection r and when at noon, the projection w releases the lever o, the left (Fig. 5) notched side of the quadrant engages and depresses the projection r to rock the dial b to show the indications 12 ... 23 through the openings c. At midnight, the quadrant is again raised and when released depresses the projection s on the dial, rocking it to show the indications 0 ... 11. The dial b is removably fitted on a flange d concentric with the hour-hand spindle x, and is apertured at g, h whereby it may be slid thereover. The pivotal arrangement of lever o on member m enables the hands to be set by reverse rotation of the spindle x without actuating the dial moving mechanism. According to the Provisional Specification, the quadrant is pivotally carried by a spring- biassed bar or rod movable in guides on the masking dial by a cam on the hour spindle.

Filed: 1922-08-22
Abstract: 198,274. Nickum, W. D. Aug. 22, 1922. Connections; depolarizing by high-pressure current.-Depolarization is effected by high-pressure currrent induced by variations in the electrolyzing current due to polarization. The high-pressure current may be in the opposite direction to the main current. In the arrangement shown, a transformer 6 has its primary 5 in series with, and its high-pressure secondary 15 in shunt to the electrodes 9, 10 and generator A. Inductances 2, 12 prevent return of secondary currents to the generator A. In a modification, the secondary winding 15 is connected to one main electrode 10 and to an auxiliary electrode. In the main circuit may also be inserted a relay magnet 4 actuating a switch arm moving between contacts 26, 27 which are connected to a battery and to signalling devices 30, 31. Evaporation, or variations in the temperature or density of the electrolyte, can thus be indicated. In this case the resistance of the secondary coil 15 must be at least as great as that of the electrolytic circuit, and the relay 4 must be designed so that the current through the secondary coil is insufficient to actuate it when the electrodes are removed from the electrolyte. The invention is applicable to electroplating and to the purification of water and sewage.
