IPC: B62K19/36
Filed: 1939-01-27
Abstract: 520,010. Saddle supports. PATRICK, T. Jan. 27, 1939, No. 2793. [Class 136 (iii)] Means for mounting a saddle on a cycle comprise a rigid railway adapted to be supported at both ends on the cycle, a saddle-carrying chassis slidable on the railway so that the saddle may occupy various positions including a position directly over the cycle pedals, and means for locking the chassis against movement on the railway.

Title: Improvements in or relating to movement determining mechanisms
IPC: F16H27/10
Filed: 1943-02-24
Abstract: 579,978. Movement controlling mechanism. SPERRY GYROSCOPE CO.,. Inc. Feb. 24, 1943, No. 3044. Convention date, Feb. 26, 1942. [Class 80 (ii)] [Also in Groups XIX and XXXVII] A mechanism for use for example for actuating a clutch or a stopping movement or for operating a counting mechanism, comprises a pair of co-axial members 13, 14, which are rotated at different speeds in the same direction and carry parts which co-o perate with one another after a lapse of time determined by the difference of speeds of the members. As shown, the members 13, 14, Fig. 5, are meshed with pinions 23, 24, connected by a clutch 32, the pinion 24 being on a shaft 29. Member 13 has a side plate 30 against which the pinion 23 is urged by a spring 31 and on which a roller 34 is mounted. A projection 35 is mounted on the member 14 at the same radial distance from the common axis of the members 13, 14, as the roller 34. The member 13 is moveable axially on its shaft. Thus, when the roller 34 rides over the projection 35, both members 13, 23, are moved axially, and' this axial movement is used to actuate a counting or measuring device which may be located on the plate 30. In a modification, for limiting the extent of movement of a member, e.g., the shaft 29, Fig. 1 (not shown) the latter carries both pinions 23, 24, and the members 13, 14, are secured to their shafts. The member 13 has fixed thereto a pin 21 and a pin 17 slidable in a hole in the member 14 is urged by a spring 20 towards the member 13. The framework 10 carries a stop 15. At the commencement of movement the pins 17, 21 register with one another so that the pin 17 projects to the right and engages one side of the stop 15. Rotation can therefore proceed in one direction only. After a predetermined movement the pins 17, 21 again register and the pin 17 is pushed to the right again and engages the other side of the stop to arrest the movement. The direction of movement is then reversed and the sequence of events is repeated. The Specification, as open to inspection under Sect. 91, comprises also the application of the invention to electric switches. This subjectmatter does not appear in the Specification as accepted.

Abstract: 980,309. Securing coils for dynamo-electric ' machines; cooling. C. A. PARSONS & CO. Ltd. Oct. 23, 1961 [Jan. 26, 1961], No. 3111/61. Heading H2A. The windings 3 in rotor slots 2 of a turbogenerator are held in position against the action of centrifugal forces by a series of members 6, one of which is secured to each of the rotor-teeth and arranged to extend over part of immediately adjacent slots. In one form, Fig. 1 (not shown) the members are T-shaped- and are secured to the rotor-teeth between adjacent slots by a " fir-tree " type of fixing, the arms of the T extending over part of an immediately adjacent slot and arranged to abut the arms of adjacent members in a direction tangential to the rotor surface. Openings may be formed in the members to coincide with radial passages in the conductors in theslots to allow the flow of cooling fluid therethrough. In the form shown in Fig. 2 the arms 6a of the member 6 are dimensioned so that a gap 9 is left between adjacent members and the cooling fluid can then flow out between the rotor and stator. The members 6 are recessed along faces 6b in contact with the surface of the rotor 1, and the rotor-teeth have projections 1a which fit into these recesses to restrict movement of the members. In the arrangement of Fig. 3 the members 6 are shaped to assist the flow of cooling fluid through passages 8. Cooling slots 10 may be provided in the rotor teeth and passages 11 are provided through the members 6, which may be of high tensile steel, titanium or light aluminium alloy. The members 6, if made of copper, may also form damping windings and may, if joined at their ends by a toothed ring fitted to the rotor, form a squirrel cage arrangement. In addition, member 6 can also be used to carry balance weights for the rotor.

Title: Improvements in or relating to pedals for cycles
IPC: B62M3/08
Filed: 1943-02-26
Abstract: 565,724. Cycle pedals. BIRMINGHAM SMALL ARMS CO., Ltd., and MAcCABE, D. A. Feb. 26,1943, No. 3173. [Class 136 (ii)] A cycle pedal comprises a pair of sheet metal blanks 1, 2, of substantially oval formation with truncated ends, each formed with a central, longitudinal, half-round channel 3 for the pedal spindle 7, the ends of the channel being enlarged to provide recesses 4 for the spindle bearing cups 8, 9, correspondingly disposed slots 5 in the flat parts of each blank providing mountings for rubber treads 10, the blanks when spot-welded or otherwise fixed together forming a frame which contains the pedal spindle 7 and cups 8, 9 and supports the treads 10, the elasticity of the treads being utilised to constitute a source of pressure by which a dust cap is anchored on the pedal. The outer curved edges of one of the blanks are bent to form flanges 11 covering the corresponding edges of the other blank. The cup 8 protrudes beyond the outer flat edges 12 of the frame and has a flange 13, Fig. 7, with diametrically-opposite gaps 14 to permit the mounting of the hemispherical dust cap 15, Fig. 5, lugs 19 on which are passed through the gaps 14 so that cutaway parts 18 in projecting webs 16 on the cap are brought into alignment with the cup flange 13, subsequent rotation of the cap bringing the webs 16 into alignment with the edges 12 of the frame. The cap is locked in this position by sheet metal clips 20, Fig. 9, mounted on the ends of the rubber treads 10, the rotation of the cap first causing the webs 16 to press the outer faces 21 of the clips inwardly against the resistance of the rubber until the webs come opposite gapped parts 22 in the clips when the rubber expands and forces the clips over the webs.
