Title: Safety parachute device
IPC: B64D17/72
Filed: 1929-08-15
Abstract: 334,365. Keller, E. March 14, 1929, [Convention date]. Parachutes.-A compound parachute comprises at least two parachutes arranged one above the other in spaced relation and connected together by cords, a fabric flue or flues being provided for conducting air from the lowermost parachute to that or those located above it in order to secure their rapid opening. A compound parachute to be worn by a pilot comprises two parachutes 6, 7, Fig. 2, of which 6 is folded and placed on straps 9, 10 and 7 is partly folded to leave downwardlyextending openings 11 which are kept open by a rim 12 stiffened by elastic material such as celluloid or by a rubber hose which may be inflated from a compressed-air container having a valve actuated by a cord connected to the aircraft as the pilot falls clear. A tearing-cord 15 attaches parachutes 6, 7 and straps 9, 10 to a belt 8 passing between folds 14 to which it gives the shape shown in Fig. 2. Cords 17, Fig. 6, are attached to the parachute rim at 18, Fig. 2, and assembled in a skein 19 pass underneath and behind parachute 7 to spring-hook connections on belt 8, and shoulder straps 9, 10; where they pass over the parachute they are bound tegether by frangible cords to form a skein 20. The fabric flue 21 and the cords for parachute 6 are folded with the latter over parachute 7. The flue 21 is held in its correct position after opening by cords 22 - - 25, Fig. 6. When the pilot jumps out, air collecting in the folds 14 causes rupture of the cords 15 to release the parachute, the parachute 7 being opened by the action of its elastic rim and parachute 6 by the air flowing through flue 21. If the pilot falls head first, release of the parachute 6, 7 by breaking cords 15 is effected by the pressure of the air in the folds of a pilot parachute 27, Fig. 2, connected to parachute 6. Fig. 7 shows a compound parachute adapted to support an aircraft. The cords of each superposed parachute are connected to the rim of that beneath it bv spring hooks to allow of detachment of individual, or the addition of extra, parachutes. An automatic release mechanism comprises a compressed-air container 35, Fig. 8, of which the valve is opened to supply air to parachute 28, Fig. 7, automatically upon the aircraft reaching a dangerous inclination. This valve is normally kept shut by a spring acting upon the valve lever 37. A fixed container 39 is partially filled with mercury which is spilled through holes 41 in its walls into a bowl 38 fixed to lever 37 when the aircraft is tilted to a dangerous extent, thus causing the weight of the lever to overcome the pressure of the spring and open the air-release valve. A collapsable basketshaped buoyant platform 45 may be arranged in cords of parachute 28 to receive the occupants of the aircraft in case of fire and to carry signalling apparatus, a release device being provided at 48, Fig. 7. In large aircraft access to the platform may be obtained by the use of rope ladders or conveyer baskets.

Title: Improvements in or relating to automatic safety locks or securing devices for vehicles, machinery and the like
IPC: B60R25/00
Filed: 1920-09-02
Abstract: 159,855. Auto Combination, Soc. Anon. March 2, 1920, [Convention date]. No Patent granted (Sealing fee not paid). Guarding against unauthorized use.-Unauthorized use of motor vehicles, aeroplanes &c. is prevented by locking means electrically or mechanically controlled by the ordinary manipulations on the part of the driver preparatory to leaving the vehicle or machine. As shown in Fig. 1, the steering column 14, or other part of the mechanism, is locked by a locking-piece 12 pressed into engagement by the rotation of a spring- pressed cam 9, after the release of an armature 8 therefrom, upon the excitation of a magnet 6, which occurs when a contact 2, 3 is closed by the opening of the car door 1. The locking- piece, in moving, breaks a contact at 12b, thereby preventing waste of current. As shown in Fig. 3, a locking wheel 14 on the steering-shaft may be engaged by teeth 12, on levers 12<c>, pivoted on a bolt 16, on a swinging frame 15, carried on the hub of the locking wheel. The levers are connected by a spring, and are held by pins 12d movable in a guide 17, itself movable in a guide 17d. Lips 12e, on the levers, pass between pins and a beam 23 on a member pivoted at 22 on a lever 20, pivoted at 19. A bolt 25, pivoted on the lever 20, can only enter a nut 26 when grooves in a hole in the nut correspond with projections on the bolt. The nut is normally held out of this position by a spring 27, and a pin, pressed into engagement by a spring 30. The gear can only be locked when the pin is withdrawn by an electromagnet and the nut turned by another magnet to admit the bolt 25, thereby permitting the lever 20 to be operated by a spring 21. To unlock the gear, the lever 20 is raised by turning the key 32, which may be under the control of a combustion lock, and operating a cam 33 as shown in Fig. 8. After the bolt 25 is withdrawn, the nut 26 is returned by the spring 27 and the pin entered in the nut by the spring 30. The key 32 is finally returned by a spring 36.

Abstract: 752,619. Electric torches. SPIROTECHNIQUE. Sept. 2, 1954 [Sept. 10, 1953], No. 25522/54. Class 39(2). An electric torch for divers is of the kind having a watertight head or unit 7 comprising a bulb 6, reflector 9 and lens 8 mounted in the open end of a cylindrical battery casing 1 and rotatable relative thereto for switching purposes, an axial trunnion 5 at the inner end of the unit 7 being mounted, with clearance, within the end of the casing and provided with at least one peripheral groove for locating a circular-sectioned resilient sealing-ring 13, axial movement of the trunnion relative to the casing 1 being prevented by projections 26 which are situated on the housing and engage the part of the trunnion between the sealing-ring and the edge of the open end of the casing. The projections 26 are provided by inwardly protruding portions of a resilient clip 25 which encircles a part of the casing provided with apertures adjacent to a peripheral groove 28 in the trunnion 5. The lamp bulb 6 is screwed into a metal socket 15 provided with a pair of outward radial fingers 16 which pass through helical slots in the wall of a cylindrical guide 18 fitted loosely within the axial bore of the trunnion 5 and extend into longitudinal slots 17 in the inside wall of the trunnion, so that rotation of the trunnion relative to the guide 18 moves the bulb socket axially to bring the centre contact of the bulb either towards or away from a spring-pressed plunger contact 24. The cylindrical guide 18 is held against rotation by a washer 19 of rubber or like material armoured with a layer or layers of metal gauze and seated upon a flange or collar 20 near the lower end of the guide, the washer being so dimensioned that its outside edge engages the inside wall of the battery casing which, in the example, is made of metal. An insulating plug 22 carrying the contact plunger 24 within a casing 23 is a push fit within the lower end of the guide 18 and is formed with a flange 21 which grips the central portion of the washer 19 against the guide flange 20. Due to the contact plunger 24 being movable relative to its casing 23 the head 7 of the torch may be further rotated after closing the bulb circuit, so that the bulb is moved axially relative to the reflector for focussing. A cap 10 screwed upon the head 7 retains the lens 8 and reflector 9 in position, the connection being made watertight by plastic sealing-rings 12. The bottom 2 of the casing is sealed by soldering or brazing around its edge.
