Title: Crank-driven mechanism
IPC: F16H21/52
Filed: 1934-12-18
Abstract: 427,298. Crank mechanism; connecting-rods. SINGER MANUFACTURING CO., Elizabeth, New Jersey, U.S.A. Dec. 18, 1934, No. 36250. Convention date, May 22. [Class 80 (iii)] [See also Group XXVI] In a crank-driven mechanism a ball member on the crank pin is embraced by a spherical big-end of the connecting- rod, the ball member and big end having registering slots in their spherical surfaces to accommodate a key disc parallel to the crank pin to prevent wobbling of the connecting rod about its axis. The invention is described in connection with a sewing-machine having a bed 1 and bracket arm 2 terminating in a head 3 in which the needle bar 4 reciprocates. The main shaft 9 is journalled in bearings 6, 7 and has crank-pins 10, 12. The crank-pin 10 is embraced by the halves 13, 13<1> of a split bush with an outer spherical surface which is embraced by the lower strapped and spherically socketed end of a connecting-rod 19 the upper end of which actuates the needle through a lever 21 and link 23. To prevent relative rotation of connecting-rod and bush and to prevent wobbling of the connecting-rod, both the members are slotted as at 24, 25, Fig. 4, to receive a key disc 26 which allows the connecting-rod to tilt to a limited extent in planes parallel to the crank-pin 10 but prevents wobbling on its longitudinal axis. A similar key disc 40 is provided between the connecting-rod 36, Fig. 3, and bearing bush 33. The crank-pin 12 has an oil duct 48 leading from an undercut oil catching groove 49, Fig. 1, overhanging one end of the main bearing 7. This duct discharges oil through a duct 50, Fig. 3, to the crank bearing surfaces and also through a duct 51 into the slot 41 and around a peripheral groove 52 in the key disc 40 to the duct 53 in the connecting-rod and thence to the ball 37, Fig. 1 connected to the looper lever 38. Similarly oil from the bearing 6 is caught by a groove 54 and fed centrifugally through duct 55 to the bearing surfaces of the bush 13, 13<1>, and also upwardly through duct 56, Fig. 4, around peripheral groove 57 and duct 58 to the ball 20. The bearings for the main shaft and looper lever are lubricated by wicks 59, 60, 62, 63.

Apparatus for exposing a workpiece 60 to a beam of charged particles causing a partial melting, e.g. for welding, comprises a source 1 of charged particles, at least one electrostatic lens 2 and an electromagnetic lens 3 for producing and shaping the beam and a waveform generator 4 connected to apply a cyclically varying potential of at least 600 c/s. to the electrostatic lens to vary the intensity distribution between the peripheral and centre zones of the beam cross-section according to the waveform of the cyclically varying potential. Generator 4 may be a conventional A.C. voltage generator supplying voltages shaped as sine waves, trapezium shaped waves, sawtooth waves and peaked pulses. The varying voltage effects a continuous focusing and defocusing at the workpiece surface. The electrostatic lens may be axially symmetrical comprising a serie s  of spaced electrodes in the form of apertured plates or tubes or a plurality of pairs of plates to which different potential waveforms are applied to effect different intensity distributions in different vertical planes simultaneously. In Fig. 1, two electrically conducting diaphragms 22 and 23 are included connected to housing 8. Stepped pulses as at (a) and (b) in Fig. 2 (not shown) produce distributions as in Figs. 3 and 4 respectively (not shown). The electrostatic lens may include a plurality of circular segmental electrode sections (21a, 21b, 21c and 21d) (Fig. 5, not shown), opposing segments 21a, 21c being connected to a different voltage generator to segments 21b and 21d, the two voltage generators producing voltages of different waveforms or the same waveforms but out of phase. The working chamber 24 may be at near atmospheric pressure, a pressure stage system being included. Compartments 26, 27, 28 and 29 may in any case be evacuated separately through pipes 30.

Title: Improvements in or relating to photographic cameras
IPC: G03B19/04
Filed: 1955-12-21
Abstract: 817,444. Photographic cameras. HEIDECKE, R., and FRANKE, H., [trading as FRANKE & HEIDECKE FABRIK PHOTOGR PRAZIONS APPARATE.]. Dec. 21, 1955 [Jan. 18, 1955], No. 36628/55. Class 98(1) When, in a photographic camera a film winding handle has been turned in one direction to wind on the film and in the reverse direction to set the shutter a pawl is resiliently urged into engagement with a notch in a disc carried by the handle to prevent further reverse rotation of the handle but is rotatable against the resilient means into another position in which the resilient means acts on the pawl in the opposite sense and in which the pawl permits the rotation of the handle to continue in the reverse direction to re-set the shutter without first winding on the film. As shown, two locking pawls 6 and 9 engage disc 3 fast with handle 2 and toothed wheel 10, respectively. There is a free-wheel connection between the disc 3 and wheel 19 permitting reverse rotation of handle 2 in direction B without moving wheel 10. On completion of the film wind, further rotation of the handle 2 in the direction A is prevented by engagement of pawl 9 with toothed wheel 10. The freewheel between disc 3 and wheel 10 permits reverse rotation until arm 6 of a three-armed pawl abuts one end of notch 4 under the spring-loading of lever 14. Thereafter further reverse rotation of the handle 2 to re-set the shutter is possible only on moving the pawl by knob 17 to the position shown in Fig. 3 in which lever 14 spring loads arm 7 into engagement with notch 4. On continued reverse rotation of handle 2 the sense in which lever 14 acts on the pawl is again reversed so that on completion of a full circle, the arm 6 is again ready for engagement with notch 4. Either the tip of arm 7 or the co-acting end of notch 4 may be rounded so that accidental setting of knob 17 for double exposure is annulled on moving handle 2 in the direction A to wind on the film. The shutter release means 12 is blocked except when arm 6 is engaged with notch 4.

Water, supplying to cylinders.-Provision is made for the injection of cooling jacket water or steam into the cylinder of an internalcombustion engine immediately before ignition takes place, an automaticallyoperated valve being employed to put the jacket space into communication with the e combustion space only when the pressure in the jacket exceeds the compression pressure. Two ball valves A and B are housed in a common duct and are forced apart against their seats by a spring 4. The valve B is actuated in timed relation to the crank-shaft by a rocker 10 and push-rods 11 and 14, whilst the valve A is spring- loaded to remain closed until the pressure on the side communicating with the jacket exceeds that admitted to the duct on the opening of the valve B. The heating of the jacket water may be assisted by the provision of tubes in the jacket through which the exhaust gases are passed. The length of the tube 5 leading from the jacket may be such that steam only is admitted to the cylinder; the water level in the jacket is maintained constant, by unspecified means, a replenishment tank being provided.
