Title: An improved rotary pocket fan
IPC: F04D25/08
Filed: 1920-12-15
Abstract: 160,752. Soc. Industrielle de Celluloid. March 26, 1920, [Convention date]. Driving-gear; impeller blades.-A pocket rotary fan has blades 27, 28, 29 which fold one over the other and are mounted loosely on a spindle 21 carried by a slide 5, 6. The slide is supported in a slideway 2 with a toothed rack 1 upon one side engaging a pinion 18 upon the spindle 17 carried by the slide. Wheels 19, 20 upon the spindles 17, 21 are also in engagement, and the spindle 21 also carries a ratchet wheel 22 which, in one direction of rotation, engages a pawl disc 23 connected by pins to the fan blades. Two fingers are held against the projections 13, 14 on the slide and the thumb is pressed against the button 3. The relative motion of the rack and slide causes rotation of the spindle 21, the teeth of the ratchet wheel 22 engage the tongues of the pawl disc 23 and cause the fan blades to rotate. Shoulders on the blades are engaged by a pin joining the discs 23, 25 when the three blades are 120‹ apart. When the stroke of the slide is completed, the manual pressure is relaxed and the spring 35 restores the slide to its original position. During this return motion the ratchet wheel slides over the tongues on the pawl disc, and the fan blades continue to rotate by reason of their momentum. In a modification, the pinion 18 carries a pawl which drives a loose wheel on the spindle 17 in one direction, but rides freely in the reverse direction.

Title: Improvements in and relating to hydraulic operating mechanism for electric switches
IPC: H01H33/34
Filed: 1930-11-25
Abstract: 363,795. Automatic circuit-breakers. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych,London.-(Assignees of Rankin, W. K. ; 267, Highland Avenue, Lansdowne, Pennsylvania, U.S.A.) Nov. 25, 1930, No. 35478. Convention date, Nov. 26, 1929. [Class 38 (v).] Fluid-actuation.-An oil circuit-breaker of the loose-handle type is adapted to be closed at a uniform velocity by fluid pressure set up by a gear pump 5 driven by an electric motor 29, the shaft 28 of which also drives a flywheel 30. The motor circuit is closed through a press-button switch 32 and, when sufficient speed is attained, a centrifugal switch comprising rotating masses 41 and slip-rings 42, 45 is closed to energize a solenoid 35 which lifts a valve 6 on to a seating 7, thereby closing the ports 8 and causing the fluid-pressure in the passage 4 to act on the piston 9 and lift it. The rod 9<1> acts on the common pivot 18 of a toggle 17, one end of which 19 is pivoted to a link 20 which is held by a latching-lever 22. Straightening of the toggle 17 therefore rotates counterclockwise about its pivot 13<1> a bell-crank lever 13 to which is pivoted at 15 the switch-actuating rod 12. When the lever 13 has rotated sufficiently, a limit switch 33 is opened to de-energize the motor 29 and pump 5, and ports 11 are uncovered to reduce the fluid pressure corresponding to the closed position of the switch connected to 12. If the switch is closed on to an overload, the solenoid 24 acts on the latching-lever 22 through a lever 25 and link 27, to free the end 19 of the toggle 17 and allow the switch to open. A manual switch 40<1> is placed in series with the centrifugal switch when it is desirable that closure of the switch should depend on the indication of a synchroscope. The flywheel may be dispensed with if the motor is of the rotating field type.
