Title: Improvements in and relating to Means for Generating and Storing Power by the Compression of Air.
Inventor: SMITHEY WALTER DUKE
IPC: F03D9/00
Filed: 1917-12-05
Abstract: 114,286. Smithey, W. D. Dec. 5, 1917. Actuating pumps; compressing-plant, general arrangement of; valves, arrangement of. - A double-acting air compressor is actuated through a crank and connecting-rod by a windmill rotatably mounted on a hollow tower, which has an internal flange for supporting the compressor, and of which the lower part forms a reservoir for the compressed air. A wind wheel of usual construction is secured to a crank shaft 7, Fig. 5, mounted in bearings 6 in a yoke 4, which is free to rotate in an annular track formed by an external flange 2 on the hollow tower 1 and a collar 5 secured to the tower. A vane is pivoted to lugs extending from the yoke 4 and may be set to position the wheel towards or away from the wind. The crank is connected by a rod 44a to the piston-rod 44, Fig. 2, of the compressor, which is supported within the tower on an annular flange 8 formed with air inlet and outlet ports 9, 10, the port 9 having an attached pipe 11 communicating with the atmosphere. A flange 14 on the cylinder 15 fits in a seat 13 in the flange 8, and a cap 29 secured on the flange has air ports and a central opening 30 with packing-rings 61 and a gland 62 for the rod 44, to which is secured a piston 42 with packing-rings 43. The inlet valves 19, 35 have guided rods each acted upon by two springs separated by nuts adjusted normally to keep the valves in open position, while the outlet valves 25, 39 are normally held closed by springs. When the wind wheel is rotating slowly, the air is not compressed sufficiently to close the inlet valves and the air is worked to and fro in the inlet passages, but when a certain velocity of the piston is reached, the inlet valves close and air is forced past the outlet valves into the reservoir formed by the lower part of the tower, from which the compressed air may be drawn through a cock for power purposes. A supply of lubricating-oil is maintained within the tower above the compressor to the level 63.

Title: Combined variable resistors, capacitors and the like and push pull switch
Inventor: MUCHER GEORGE JOHN
IPC: H01C10/36
Filed: 1953-06-29
Abstract: 739,205. Switches held set and freed mechanically. CLAROSTAT MANUFACTURING CO., Inc. June 29, 1953, No. 17992/53. Class 38 (5). Two or more rotary and independent variable resistors, capacitors, &c. 13, 14, are actuated by concentric shafts 17, 18, the inner shaft being axially movable to actuate an independent switch having a fixed contact 23 and a movable contact 25 which can be disengaged from the fixed contact by the end of the shaft 18. The latter may carry an insulating member or an insulating strip 26 may cover the contact 25 as shown in Fig. 2. The sliding shaft 18 is held in its " on " and " off " positions by two dentents 36 which enter grooves 37 in the shaft. The detents extend from a member 32, Fig. 6, which is fixed in the casing and has a cut-away part 33 which engages in a groove 31 in a bushing 30. The end of the shaft 18 is formed with a slot 28 in which a part 29 of the member 13 engages. Member 13 is thus rotated by the rotation of the shaft 18 but is unaffected by the axial movement of the shaft to move the contact 25.

IPC: F16D41/24
Filed: 1972-04-19
Abstract: 1354061 Coaster hubs FICHTEL & SACHS AG 19 April 1972 [23 April 1971 (2)] 18170/72 Heading B7E [Also in Division F2]  A coaster hub for a cycle comprises a driving sleeve 205 helically splined to a clutch cone 211 which, when the hub 205 is rotated in the forward pedalling direction, is moved left into engagement with a cone surface on a driven hub 204. When the driving sleeve 205 is rotated in the back-pedalling direction the clutch cone 211 moves right into engagement with brake discs 212 which are tilted into frictional engagement with an interior surface of the hub 204. The brake discs are carried by a non-rotatable sleeve 213 having a square section which passes through rectangular apertures in the brake discs. The brake discs have an elliptic outer periphery. In Fig. 5 (not shown) the cone clutch is replaced by a tilting disc clutch. In Fig. 6 (not shown) tiltable discs (463) are mounted on an axially slidable sleeve (461) which is helically splined to a driving hub (457). When the hub (457) is rotated in the forward pedalling direction the discs (463) are tilted into engagement with a driven hub (454). When the hub (457) is rotated in the back-pedalling direction the sleeve (461) is moved axially right to engage teeth (464) with teeth (465) on a fixed hub (455) to prevent rotation of the sleeve (461) and discs (463). Thereafter the discs (463) are tilted into braking engagement with the hub (454).

Abstract: 799,081. Electromagnetic brakes. SPERRY RAND CORPORATION. June 13, 1956 [June 13, 1955], No. 18334/56. Class 103 (1). [Also in Group XXIV], A control mechanism for record operating means comprises a rotary armature and a longitudinally movable pressure member for transmitting a drive from a driving gear to a shaft having a drive plate secured thereon, the pressure member being in yieldable non-driving contact with the shaft until a magnet is energized to attract the armature and move the pressure member into driving engagement with the shaft. A driven shaft 57 carrying a capstan 62 for a magnetic tape T is driven from a motor 10 directly through a forward clutch 47, 53 or through a countershaft reverse gear train 27, 23, 24, 32 and a reverse clutch 72, 74, an electromagnetic brake 89, 74 being engaged when either of the two clutches are not energized. The driving shaft 11 carries a gear sleeve 28 to which is secured a spanner member 36 having projections 41 engaging a disc 38, similar projections on a second spanner member 37 also engage the disc to provide an axially flexible coupling, lightly loaded by a spring 33, between the gear sleeve 28 and an armature 42. The armature 42 is secured by tangential taper pins 44 to a sleeve 46, passing through a stationary clutch coil 52, integral with a clutch disc 47 having a friction facing 54. An opposed clutch disc 53 is secured to the shaft 57, the friction facings 54 being held in non-driving engagement by the spring 34 when the coil 52 is not energized to engage the clutch. A second sleeve 66 is similarly axially loaded by a spring 54 through a cup 68 and bearing 67 and is driven by the gear 32 of the reverse train to provide reverse rotation to the shaft 57 through friction surfaces 73 on energization of a magnetic coil 77. The clutch disc 74 pinned to the shaft 57 also co-operates with a brake disc 89 through friction surfaces 91, the disc 89 being integral with a sleeve 88 secured by tangential taper pins 92 to a coupling 102, 101, 99 similar to the coupling 36, 37, 38 secured to the frame 13 of the mechanism. The two clutches and the brake are in non-driving contact when disengaged and are arranged to operate singly. Specification 793,339, [Group XIX], is referred to.

The rotor spindle is carried in bearings in bridge members 3, 4 forming part of the annulus 1. A pair of brass pillars 7 are attached to the rear face of the annulus and carry the shunt magnet 6, the lower part of which is attached to brackets 8 carried by the annulus 1. A lower pair of brass pillars 7<1> carry the series magnet 5. The magnets 5, 6 are magnetically connected at the rear by an iron stamping (not shown). The brake magnet annulus 1 is attached to the meter case by pillars passing through holes 10. The indicating mechanism may be clamped to the brake magnet annulus or fixed to brackets carried by the case. The rotor spindle may alternatively be mounted in bearings attached by pillars or brackets to the rear wall of the iron case. The shunt and series magnets may be connected directly to the case which then serves as the magnetic connection between them. In a polyphase meter, two or more driving elements are carried by the brake magnets.
