Definitions

  • This invention is concerned with vibratory choppers designed to chop or interrupt a direct current to result in an alternating current.
  • the intervening space between the contacts must be made comparatively small (from .05 to .1 mm).
  • the contact pieces come together they should snugly engage -throughout their whole surface.
  • the biasing tension' of the counter spring as a general rule must have a denite value; hence, not only the distance, but also the biasing tension must be adjusted.
  • Fig. 1 A modern and widely used form of construction of a chopper is illustrated in Fig. 1 (the exciting coil having been omitted in the drawing).
  • l denotes the vibratory spring
  • 2 the contacts
  • 3 the counter spring
  • 4 the abutment or stop designed to prevent the counter spring 3 from defiecting in the direction of the vibratory spring.
  • the distance between the working contacts 2 asa general rule is adjusted by adjustment of the abutment 4, the biasing of the spring 3 against the abutment 4 having to be set by adjustment of the spring 3 to the proper value.
  • adjustment involves the drawback that one of the contact supporting springs or blades must be bent.
  • this spring 3 has elastic properties this involves a chance of later changes in the properties of the spring 3. This drawback is obviated by the invention.
  • the counter springs with their abutments are inter-connected outside the union joining all of the spring blades and the ⁇ insulation parts. As a result the position relareed.
  • the counter spring 3 may be made of adequate constructional length it will be advantageous to bevel or chamier the insulated layers 6 between the vibratory spring and the counter spring on the end facing the support so that the base points of the vibratory spring andthe counter spring will come to lie roughly at the same level.
  • the counter spring 3, Fig. 2, as illustrated is preferably fastened on the side of the support facing the vibratory spring in order that the thickness (of the wall) of the support need not be taken into consideration when choosing the distance of the spring.
  • a pair o! cooperating contact elements a resilient vibratory reed having one of said contact elements mounted thereon, an insulating supporting block, means for mounting the vibratory reed on one face of 'said supporting block, an adjustable arm one end of which is xed to the opposite face of said supporting block, a counter reed having the other of said contact elements mounted thereon, means for attaching the counter reed to the free portion of said adjustable arm, a stop member also mounted on theiree portion of said arm and adjustable relative to the counter reed so as to limit to any desired amount the deection of the counter reed in the direction of the vibratory element, said arm being arranged to be adjusted so as to adjust the position of both the counter ree'd and the stop member as a unit relative to the vibartory reed without affecting the adjustment of the stop member relative to the counter HANS mams.
