Title: A machine for grinding work pieces and tools
IPC: B23Q11/00
Filed: 1954-05-25
Abstract: 757,833. Grinding machines. MARTIN & CIE. May 25, 1954 [Aug. 17, 1953], No. 15449/54. Class 60 A grinding machine comprises a stationary frame A, Fig. 2, a longitudinallymovable carriage B having a support for the work, and a transversely-moveable carriage C, a carrier I for the grinding wheel spindle G, which is mounted so as to pivot round a horizontal axis Y-Y<SP>1</SP>, Fig. 5, and a motor H driving the spindle being carried by a slide 4 which is vertically movable inside an upright 1 mounted on the carriage C and adapted to be turned about a vertical axis X-X<SP>1</SP>. The carriage B may be moved hydraulically or by rack and pinion gear operated by handwheels D-D while the carriage C is moved by a screw 24, Fig. 6, and a nut 25 which is in splined engagement with the underside of the carriage C. The clearances in this mechanism are taken up by fluid pressure admitted through a port 29 to an annular space between a piston 21 connected to the carriage C and a sleeve 23. A bore through the piston 21, however, allows pressure fluid to flow to the space at the left-hand side of the piston 21 to cause a rapid hydraulic traverse 237 of the carriage C to the right when required. The screw 24 may be rotated directly by a handwheel F or through gearing by a second handwheel (not shown). Fig. 5 shows the mechanism for adjusting the slide 4 in the upright 1. This comprises a screw 5 which is subjected to fluid pressure from a pipe 21 to support the weight of the slide assembly and in threaded engagement with one of a pair of bevel gears 6, 9 rotated directly by a handweel 13 or through gears by a handwheel 14. For sharpening helically-toothed cutters, a headstock K, Fig. 9. mounted on the carriage B is provided and an angular oscillation imparted to the spindle 39 by the reciprocation of the carriage by means of a transversely-moveable bar 49, Fig. 11, which engages an angularly-adjustable bar 45 fixed to the frame A. The bar 45 is connected by a pair of steel tapes 52, 55 to a pulley 51 which drives the spindle through a worm gear 58, 66, a spring- loaded catch 63 and a dividing head 64. The worm 58 may be locked to'the tailstock body by a spring-loaded plunger 60 and the spindle 39 gradually adjusted by the worm 66 when setting up for the first cut, the workpiece being rotated for subsequent cuts by the dividing head 64. The work support may be angularly adjustable on the carriage B.

Title: Control Circuit for Apparatus for Treating Hair.
Inventor: EDIS JACK HAROLD
IPC: A45D19/16
Filed: 1968-03-30
Abstract: 1,187,001. Switching circuits for heating apparatus. PIFCO Ltd. 10 Feb., 1969 [30 March, 1968], No. 15468/68. Heading H2H. Control circuit, for apparatus for steaming and drying hair, includes thermostatic and thermal switches which operate heating elements for providing steam and hot air and also a fan. In operation, a selector switch SD1/2 is first set to a position in which contacts SD1 are open and contacts SD2 are closed. A control switch CS is now moved to an on position so that current flows by way of a thermostat switch ST and contacts SD2 to a heating element ES which causes steam to be generated. When all the water has boiled, the temperature of the element ES will rise, and this causes the switch ST to open, whereupon current will flow through resistors E1 and E2. Resistor E2 serves to maintain switch ST open, and resistor E1, after a delay, operates a thermal switch TS which switches on a fan motor MW to drive air heated by resistors ED1-3 which are simultaneously switched on. According tothe setting of the control switch CS, all the resistors ED1-3 may be energized, or alternatively only two or more at all may be switched on. Theapparatus is switched off manually when drying is complete. If the apparatus is required for use solely as a drier, the selectorswitch SD1/2 is moved to its other position so that contacts SD1 are closed and contacts SD2 are open. Only the fan motor and air heaters ED1-3 can now be energized. A safety thermostat T switches off the supply to resistors ED1-3 if these should overheat.

Title: Improvements in and relating to mechanical gear shift
IPC: F16H63/46
Filed: 1925-06-22
Abstract: 236,212. United States Automatic Shift Co., (Assignees of Allen, J. S.). June 30, 1924, [Convention date]. Controlling variable-speed gearing.-Speed changes are effected by actuating-slides 2, 3 which are reciprocated in opposite directions by the main clutch lever 21<e> of a vehicle, selection being made from the steering wheel while the gears are in neutral with the clutch lever depressed. A lug-carrying selector disc 9 slides on a feather on a shaft 10, which is turned through a lever 30 to select, there being an elastic coupling 16 to allow the disc 9 to lag and to follow when allowed to do so by the return of the parts to neutral. The slides 2, 3 are connected by a medially pivoted lever 6, and the lever 21<c> is jointed to a third slide 21 within the gear case 1. The gear-shifting forks are secured to two slidable bars 4, 5, and the function of the disc 9 is to lock either striking bar to either of the slides 2, 3 so that either striking bar can be moved in either direction on release of the clutch pedal. Depression of the clutch pedal to disengage the main clutch brings the parts to neutral. The disc 9 being then free to turn, takes its position for the new selected speed. Thus in Fig. 4, the striker 4 is locked to be actuated by the slider 2. On release of the clutch lever, the slider 3 and striker 5 prevent the disc from turning. A spring pawl 20 is carried by the third slider 21 to free the clutch mechanism from the gear control just prior to the engagement of the clutch. On the return of the clutch pedal, the pawl 20 engages a pin 23 upon a yoke 22 fast on the slider 3, and is pushing the gears into mesh. A cam 36, Fig. 2, on the pawl slides along a fixed roller 27 until a swell is reached which tilts the pawl clear of the pin 23. The pedal 21<c> moves on and the gear change is completed by a spring 25, Fig. 1. Thus the clutch engages only after the completion of the change. The whole device with its casing is a unit which can be fitted as such.
