Abstract: 283,821. Noguchi, T. Sept, 21, 1927. Mounting.-A fan mounted on the shaft 11 is driven by the electric motor 1 the casing of which can be clamped by a screw 5 to a supporting vertical spindle 3 resting in ball bearings in a stand 2. Electric current is supplied to the motor through slip rings 8 and a lead 7 which passes through the spindle 3. The end of the shaft 11 remote from the fan, drives a vertical shaft 12 through worm gear which may be moved into engagement by the operation of the knob 13. A sleeve 14 is mounted to slide on the spindle 12 and is normally held in its upper position by a spring 19. Another sleeve 21 is slidably mounted on the sleeve 14 and has an expanded base which carries a frictional ring 22 of rubber or the like. Spring pressed balls 18 in the sleeve 21 engage grooves 18a, 18b in the sleeve 14 in the upper and lower positions respectively of the outer sleeve 21. A stud 24 on the end plate 23 of the outer sleeve is connected by a link 25 with a universal joint at each end to a cap 27, which can be screwed on to a projection 26 on the stand 2. With the worm-gear disconnected the motor simply rotates the fan, but when the worm-gear is moved into engagement by the knob 13, and the friction ring 22 is moved to engage the spherical part 9 of the standard 2, the fan head will be caused to oscillate while the cap 27 is screwed to the projection 26 as shown in Fig. 1. If the cap is removed from the projection the fan head will rotate continuously round the stand. A polygonal ring may be substituted for the circular ring 22 and the fan head then rotates intermittently.

Title: Self-closing cover plate for air shafts or emergency exits of shelters, particularlyunderground shelters
IPC: A62B13/00
Filed: 1962-06-29
Abstract: 945,782. Fluid-pressure servomotor control systems. M. VON UNSINGEN, [trading as BOCHUMER EISENHUTTE HEINTZMANN & CO]. June 29,1962 [July 3, 1961], No. 25015/62. Heading G3P. [Also in Division E2] The cover plate 2 of an underground or other shelter, air shaft or emergency exit 1, Fig. 1, is attached to a piston 9 slidable in a cylinder 5 having conduits 11e, 12 leading thereto. To open the cover 2 a solenoid is energized to unseat a valve 13, Fig. 3, and retract an associated lock 21 from a groove 22 in the rod 3 of the piston 9 so enabling fluid from a source X to retract a piston 14 from a locked position in groove 22 and open a valve 15 so that fluid branching from upstream of the piston 14 flows therethrough into a line 11c having a branch 11b to atmosphere which is closed when the valve 13 opens the described path for the fluid from source X. Line 11c leads via a valve 16, open when the cover plate is closed, a valve 17 and the conduit 11e to the cylinder 5. In the elevated position of the piston 9 the valve 16 is spring closed when a feeler 25a engages a recess 26, Fig. 1, in the rod 3. The conduit 12, Fig. 3, is connected to atmosphere 12 through a normallyclosed solenoid-actuated valve 18 integral with the valve 17, and a throttle valve 19. The valve 19 is responsive to impulses, e.g. from a Geiger counter or thermal fuse; it is also actuable by a trip device 27 responsive to impact or pressure waves. Upon operation of the valve 18 the cylinder 5 is connected to atmosphere 8 via valves 18,19 and the pressure supply to the cylinder is cut-off by closure of valve 17; the feeler 25a disengages the recess 26 and the valve 16 opens. Prior to complete closure of the cover plate a cam trip 28 thereon engages and rotates a lever 19a of the throttle valve 19 to effect a throttling of the exhausting fluid and hence braking of the cover plate in a pre-sealing zone; the cam 28 then fully opens valve 19 to facilitate the final sealing movement of the cover plate. Before this position is reached the valve 13 and piston 14 enter the groove 22 to lock the cover plate. Any downward movement of the piston 9 due to leakage causes opening of the valve 16 and re-elevation of the piston and cover plate.

Thus, as the slidable clutch member is moved, the engagement between the pairs of teeth upon synchronization is facilitated. As applied to a two-speed axle construction, the member B is part of a carrier 21 having planet pinions 23 meshing with the teeth 25 and with an internally-toothed annulus 28 formed on a crown-wheel 12. The carrier 21 has differential pinions 19 meshing with bevel-wheels 18 on the half axles 16. In the position shown in Fig. 1, the slidable clutch member is held stationary by the teeth 26 so that the carrier 21 is rotated by the annulus 28 to drive the axles 16 at low speed. To drive the axles at higher speed, the slidable clutch member is moved to the left by a shifter fork 26<1> to disengage the teeth 26 from the member A and engage the teeth 25 also with the member B so that the carrier 21 is driven at the same speed as the crown-wheel 12. Synchronization of the clutch members may be obtained by closing the accelerator throttle and then opening it gradually.
