[Class 112] In a sewing-machine, the needle-actuating shaft is directly coupled to a feed shaft to drive it at the same speed, and also directly coupled to a rotary hook actuating shaft to rotate it at twice the speed. The needledriving shaft 7 is connected to the rotary hook shaft 9 by a belt 12 passing over pulleys 10, 11, the ratio of the pulleys being 1 : 2. The feed shaft 18 is connected to the shaft 7 by a belt 20 and equal pulleys 19, 21. The feed mechanism is as described in Specification 435,303. The eccentric 23 is adjusted to vary the feed by the finger lever 25 which engages a notch 24 and holds the eccentric while the shaft is partly rotated. The feed rocker 34 is operated by a pitman 38 secured at one end to the eccentric 23. Separate means are provided for raising the presser foot and simultaneously releasing the tension and comprise a finger lever 79, Fig. 6, and a treadle-controlled lever 80 pivoted at 81. The lever 80 has an arm overlying the eccentric part of the lever 79 and when the lever is swung about its pivot, the cam portion engages the arm and swings the lever 80 about its pivot. The lever 80 is connected to the presser bar by the arm 84. The tension is released by a cam 92 which engages the releasing pin and is actuated about the pivot 90 by the lever 91 engaged by the cam 82 on the arm 80. Throat plate. To prevent " looping " of the needle thread, a cup-shaped button 97, Fig. 11 is provided on the underside of the throat plate 94 to prevent " kinking" or " snarling " of the thread. Lubricating. Lubricant collects in a depression 100 in the machine head and is supplied to the needle shaft bearings by a wick 101 which feeds a pad 102.

Filed: 1975-04-30
Abstract: 1498465 Gas opacimeter ROBERT BOSCH GmbH 30 April 1975 [28 May 1974] 17903/75 Heading G1A A gas opacimeter comprises means for passing a light beam through a gas chamber 10 via entrance and exit holes 15 and 16 with shutters 40, 41 displaceable to at least partly open the holes, and notatable discs 21, 22, of which 21 interrupts the light beam. The exhaust pipe of an internal combustion engine is connected to inlet 13. Pump 12 supplies pure air to comparison chamber 11. The discs rotate in a direction corresponding to the gas flow, and are so close to openings 15, 16, 19, 20 that a laminar boundary gas layer appears on their surfaces. A resistance wire for measuring temperature extends the length of chamber 10. Baffles 2 and 4 are for uniform gas distribution, Interference filter 28, focusing lenses 29, 33 polarization filter 30 and apertured diaphragms 34 are arranged in the beams. A filter with a narrow ultraviolet pass range is used with white light source 25. Opaque, 31, and translucent, 32, sectors on disc 21 are respectively oposite openings 15 and 19 simultaneously and vice versa. Light conductors 35, 36 lead to sensor 37 of colour sensitivity corresponding to the human eye. An indication of opacity is derived from the difference of the signals due to chambers 10 and 11. Holes 15, 16 are open only when measuring to avoid dirt deposit on discs 21, 22. Shutters 40, 41, which are displaced perpendicularly to the gas flow by an electromagnet may be set to partly close the holes to simulate specific opacities.

Abstract: 1,176,234. Hook fastenings. M. R. HANCOCK. 19 April, 1968 [19 April, 1967], No. 17911 /67. Heading E2A. A self locking hooking device incorporates a hook member 11 having a hook 12 with an opening of sufficient size to permit insertion of a tube 15 or cylinder to which the device is to be hooked and locked, a jaw member 19 pivotally mounted to the hook member and biassed from a first position where it permits entry into and removal from the hook of the tube or cylinder, to a second position where it restricts entry into and removal from the hook of the tube or cylinder, a trigger member 21 slidable with respect to the jaw member between a retracted position where it permits pivotal movement of the jaw and trigger members together and a projecting position where it engages an abutment 28 which prevents pivotal movement of the jaw and trigger members together, the trigger member being biassed into its projecting position and in that position having a portion projecting beyond the jaw member so that on pressing the tube or cylinder into the hook the tube or cylinder deflects the trigger member to the retracted position thereby releasing the jaw member for pivotal movement to permit access of the tube or cylinder into the hook, the bias of the trigger member returning this to the projecting position to lock the jaw member in its second position thereby locking the tube or cylinder in the hook. In the construction shown there are two of said jaw members 19 which are spaced apart the trigger member being disposed between them; the trigger member is provided with slots 22 and the jaw members are provided with pins 23 which enter the slots to guide the trigger member in its sliding movement relative to the jaw members, the pins being formed by partially punching holes in the jaw members, the partially punched out portions providing the pins. The two jaw members and the trigger member are biassed by a spring 25 which engages a projection 26 of the trigger member. When the tube or cylinder has been removed projections 29 at the rear of the jaw member s19 maintain the jaw members in substantially the tube engaging positions by bearing against the shoulders 31 of the hook member 11. The trigger member is so disposed with respect to the jaw members that it is held away from the tube or cylinder so that it is not operated by material deposited on the surface of the tube or cylinder; the pivot pin 24 which secures the jaw members to the hook member is removable. The hook member is provided with a tubular shank 13 which engages in the end portion of a tube 14.

Title: Improved Mechanism or Mechanical Motion for Imparting Alternate Slow and Quick Motions.
Inventor: BROWN PERCY
IPC: B23F23/00
Filed: 1916-12-20
Abstract: 126,334. Brown, P., and Bostock, F. J. Dec. 20. 1916. Reversing-gearing. - In reversing or quick-return motions, specially applicable for driving the saddle carrying the cutters for cutting the teeth of doublehelical wheels, two epicyclic gears are employed, one member of each gear being connected to the driven shaft and one member of each gear being interconnected through gearing which may be used to actuate a secondary driven part such as a feed-shaft. In the form shown in Fig. 1, the main drive of the machine drives a spur-wheel k integral with a pinion b<4> gearing with planet-pinions b loose on arms c<1> secured on the shaft d, which drives the cutters through screw-and-nut means. The pinions b gear with a wheel b<3> geared through change-gearing g<1> to a spindle g, which may drive the feed motion and is geared through a shaft f and worm to a worm-wheel e turning with a pinion a<2> geared to planet-pinions a loose on the arms c'. A pinion a<3> gears with the pinions a and carries a wheel i gearing with a wheel j forming one of a train of gears controlled by a dividing-motion, which train is automatically stopped when the slow cutting-stroke is required, the shaft d then rotating slowly in the reverse direction to the wheel k. For the quick return stroke, the wheel j is automatically released and, the resistance to motion of the shaft g<2> being greater than that of the shaft d, the wheel b<3> remains stationary, the shaft then rotating more quickly in the forward direction. The two epicyclic trains may be separated, each planet-carrier being separately connected to the shaft d. The members of the trains may be connected up in different order to the various driving and driven parts. Spur gearing may be substituted for bevel gearing.
