Abstract: 539,222. -Typewriters. ROYAL TYPEWRITER CO., Inc. Feb. 27, 1940, No. 8293/41. Convention date, March 9, 1939. Divided out of 539,192. [Class 100 (iv)] In a typewriter having automatic carriagereturning mechanism a manual line - spacing lever is yieldably held in operative position, so that if the operator's hand is caught between the lever and the framework during automatic carriage - return, the lever can yield to prevent injury. The linespacing lever 263 shown in Fig. 1, is pivoted on a screw 262 and has a shoulder 264 abutting on a lever 260 which engages a slot 258 in a link 256 connected to the rock - arm 4 carrying the line-spacing pawl 3. Accidental separation of the levers 263, 260 is prevented by a projection and recess 266 which are held in engagement by a spring- washer 268. The rock-arm is, as described in Specification 539,192, connected by a link 248 and levers 243, 238 to a draw-band F which is operated during automatic carriage-return.

Abstract: 214,607. Soetman, G., Vorster, B. C. A., Soer, H., Grond, A. J. K., and Elias, C. A., (trading as Syndicaat Soetman, C. S.). April 17, 1923, [Convention date]. Weft inserters not carrying bobbins, cops, and the like, looms with.-The weft from a stationary cop &c. 62, Fig. 1, is passed through a slot in a main " shuttle " or weft-inserter 5 which is picked across a main lay 1 from a - shuttle box 3 into a shuttle box 4. The loop of weft inserted by the " shuttle " passes the selvedge-forming or locking thread from an auxiliary shuttle 12, which has just been picked from a shuttle box 10 to a shuttle box 11 across a shuttle rail 8 at right angles to the lay. The lay now beats up and the loop 61 of weft is engaged and spread by projections 57 on the shuttle box 10, so that when the auxiliary shuttle is picked back into the box 10, the selvedge thread passes between the upper and lower threads in the loop, ande when the lay retires and the main " shuttle " is picked back into the box 3, the loop is held at the selvedge. The lay finally beats up agais.

Abstract: 896,823. Magnetic record apparatus. NATIONAL CASH REGISTER CO. March 10, 1961 [March 15, 1960], No. 8789/61. Class 40 (2). [Also in Group XIX A random access magnetic data storage apparatus 20, Fig. 1, comprises a plurality of individual endless tape transport units 22, Fig. 2, arranged concentrically around a central axis supporting a transducer head assembly 30 on an arm 48 which is swung to selectively engage any one of the tapes 24 at a point between a particular pair of guide rollers 66, 68. The tapes are multi-track and the head assembly 30 comprises a similar number of head units arranged side-byside and selectively connected as required by means of a multi-core cable 50. In the embodiment described, a further bank of tape transport units is mounted on the back panel 34, a further arm 48a, Fig. 8, carrying another transducer assembly 30a on the same shaft 47 carrying the transducer assembly 30. The tape transports are constantly driven by belts 43, Fig. 10, from a motor 38 or 40. A circuit diagram is shown, Fig. 11, relating to the description of the method of driving and locating the transducer assemblies in a desired position whereby position signals are derived from a potentiometer 126 driven by the shaft 47 to  operate circuits and cause the shaft 47 to be driven via magnetic clutches 110a or 110b (according to the direction of rotation necessary). Belts 112a and 112b are for this purpose driven continuously in opposite directions by a motor 104. At the same time as one of the magnetic clutches is operated the circuit of a solenoid 122 is closed to release a brake shoe 118 holding the shaft 47 from rotation. When the shaft 47 reaches the desired position the magnetic clutch and brake circuits are broken, a rotary solenoid 86 is operated to move a lever 92 coupled to a shaft 82 carrying the transducer assembly 30 and coupled also to a rod 98 having a locating- point 98a which registers in a recess 100 in the tape transport units. The magnitudes of the movements of shaft 82 and rod 98 are so arranged that the point 98a is not clear of the tape transport unit until the transducer assembly is clear of guide-rollers 66, 68.

Filed: 1918-05-28
Abstract: 122,350. Wijk, h. G. van. March 7, 1918, [Convention date]. Automatic circuit - breakers. - A .rotary, free handle overload cut-out has a fixed contact 29 and a movable spring contact 28 both mounted on a disk 22 adapted to be rotated on the fixed spindle 8, projecting from the enclosing casing 3 of the overload coil 5, by a handle 34 fixed to an elongated boss of the disk. On this boss, a locking and tripping disk 19 is mounted, and is capable of some rotation in relation thereto by a pin-and-slot connexion. The closed position of the switch is shown in Fig. 2, in which the disk 19 is locked by a detent 16 against rotation in the direction of the arrow .under the action of a spring 23. On overload, this detent is tripped by a projection 13 on the armature 9, and the disk 19 rotates until a roller on a pivoted arm 25, which carries the movable contact, moves under the action of a spring 30 on the pivot 24 into a cut-away portion 27 of the disk, thereby breaking the contact. To re-set the switch, the handle is first turned in a clockwise direction to carry the disk 19 into the locking-position and then reversed to carry the roller out of the slot. A fuse is provided on the switch for heavy overloads.
