Abstract: 1506119 Mechanical switches DAINI SEIKOSHA KK 19 July 1976 [24 July 1975 (3)] 29957/76 Heading H1N [Also in Division G3] An electric switch for operating the timeadjusting mechanism of an electric timepiece comprises one or more apertures in an electrically insulating base plate, a contact terminal formed on the inner surface of each aperture, and a pivotally mounted contact located'in each aperture. In the embodiment of Fig. 1 movement of an operating member 1 along its axis rotates a plate 15 about a pivot 14 by means of an intermediate plate 3 rotating about a pivot 2, plate 15 carrying the contacts 17, 18 for engagement with the contact terminals 24, 25 in apertures 20, 21 and plate 3 having a recess 13 which engages a projection 16 on plate 15 and carrying a pin 4 which engages a recess in member 1, plate 3 also carrying a pin 6 which cooperates with recesses 8, 9, 10 on a flexible arm 12 to act as a detent. In the embodiment of Fig. 4c the operating member 101 carries a cam 102 such that rotation of member 101 in one direction causes the plate 105 carrying the contacts 109, 110 to rotate clockwise against the restoring action of a flexible arm 107 to engage contact 110 with contact terminal 118, while rotation in the opposite direction causes the part 108 of plate 105 carrying the contacts to be bent away from the base plate 112 so that contact 109, which projects into the aperture 113, comes into contact with the contact terminal 117.

Title: Improvements in and relating to means for securing relative motion in two dimensionsbetween an object and means for operating thereon
IPC: B44B3/04
Filed: 1937-11-08
Abstract: 505,437. Copying by scanning. DALTON, J. W., and BARTHOLOMEW, H. G. Nov. 8, 1937, No. 30565. [Class 40 (iii)] [Also in Group XXII] Apparatus for obtaining relative motion n two dimensions between an object, such as a metal plate, and a device, such as an engraving tool for operating thereon, comprises a pneumatic or hydraulic cylinder 4 operating a carriage consisting of fixed and adjustable arms 7, 3 respectively, between which the work plate 1 is supported in a slide 8, the movements of the cylinder serving to impart movement to the work in one dimension, while at each end of the travel the slide 8 is given a step-bystep movement along the arms in the second climension so that the whole surface of the plate is progressively scanned by the operating device. The slide 8 is moved by rack-andpinion gearing 10 operated from a spindle 28 and the cylinder 5 is reciprocated over a fixed tubular piston rod 15 by.fluid from a pump 20. Ports 18, 18a. direct fluid to one end or other of the cylinder, the control being effected by a valve element 24 which is rotated through 180‹ at each end of the cylinder travel. In order to operate the valve, a spindle 28 carries a toothed member 27 coacting at the end of the movement to the left with a bushing 29 having an external helical groove engaging helical webs in a bushing 30. When the member 27 engages the bushing the latter moves back against a spring 32 and is thereby rotated until its teeth engage the recesses of member 27. The spring is then released, thus rotating the member 27 and spindle 28 to actuate gearing 13, 12, 10 and impart a feed step to the slide 8. The movement of spindle 28 is also transmitted by gears 36, 37, to rotate the valve 24 through 180‹ and reverse the cylinder movement. Similar means are effective at the other end of the stroke to cause reversal of the cylinder and another cross feed movement of the slide 8. The work support may be adjusted by hand from a crank 39. Specification 481,985 is referred to.
