Definitions

  • This invention pertains to adjustment means, especially for telegraph instruments.
  • the invention pertains to frame construction for telegraph instruments in which adjustment means is embodied in the supporting frame of the structure to adjust relative positions of operating members of the telegraph instrument.V
  • Past practice in assembling mutually adjustable parts has been to make one part slidable or rotatable upon the other, or upon a frame member supporting the other.
  • the object of this invention is to simplify adjustment by mounting a plurality oi cooperative members rigidly or non-adjustably upon a supporting frame, the frame itself being formed with a yielding portion between the ⁇ mounted members with provision for deforming the yielding portion to change relative positions oi the mounted members.
  • This object is accomplished by constructing a supporting frame having comparatively heavy or angularly braced rigid portions integral with comparatively light, weak, or unbraced intervening portions, the rigid portions having facilities for springs and screw members whereby they may be forced through small differences of relative position by virtue of bending or twisting the weaker portions of the frame.
  • cooperative parts of the instrument may be iixed to the frame members, in close approximation to desired relative positions and final adjustment may be made by bending the frame structure according to this invention.
  • FIG. 1 illustrates a frame structure with adjustment parts added
  • Fig. 2 is a sectional view of a complete assembly, embodying also a modification
  • Fig. 3 illustrates a frame structure as in Fig. i with further adjustment parts and operating parts added.
  • a frame casting indicated generally by numeral' I, comprises columns 2, 3, side beams 4, 5, and cross braces 6, 1, all forming a single rigid vmain frame portion, with which is associated a further rigid frame portion indicated generally by numeral 8 and comprising columns I I, I2, and a horizontal bar I3, with head I4, and cross head bar I5.
  • Side beam 4 has full rigidity at the (Cl. TIS-lll) junction between beam 4 and web 2i while side beam 5 is weakened by slot iE.
  • the slot I6 may be widened or narrowed to a small extent by adjustment members comprising a compression spring il and a screw i8, the extent of such adjustment being limited by a bushing IIS which surrounds the screw I8.
  • the rigid frame member 8 is integral with the frame I through two webs 2l, 22, relatively thin as compared with frame portions 4, 5.
  • Frame member B may be moved relatively to columns 2, 3, by adjustment members comprising compression spring 24 and screw 25 having a head 2E of large diameter. Movement of member 8 in response to screw 25 is limited to less than a single turn of the screw by two abutments; namely, 2l on the screw and 28 on the frame brace 6.
  • a further precaution against bending the webs 2 I 22 beyond limits of elasticity is provided in lugs 29, 3l) formed on the frame column 3 in the path of the cross head bar I5, a maximum separation between adjacent lugs being equal to maximum permissible motion of cross head bar I5.
  • contact springs 3l, 38 for remote control of connections in response to armature lever 35 are mounted on frame member I3 by means of insulation block 4l.
  • the spring 38 engages an adjustment screw 48.
  • a boss 49 on lever 35 presses the contact spring 3l into engagement with contact spring 38 by tension of spring 45 when magnet 36 is not energized.
  • Position of lever 35 relative to magnet 36 may be adjusted by means of screw 48.
  • Spiral 33 and shaft 50 are carried in journals 5i, 52, which are clamped on tops of columns 2, 3 by clamp members 53, 54.
  • the screw i8 is operated, thus moving downward or upward the web 22 and producing a torsion in the web 2 I, thereby tilting the axis oi' the torsional spring hinge 42 and accordingly tilting the rigid frame member 8, together with the armature lever 35 and the platen blade 34.
  • screw 25 is operated, thus moving upward or downward that rigid portion 8 of the frame comprising frameI elements I i. i2, I3 and carrying upon them the magnet 36.
  • a pair of elements requiring predetermined separation and parallelism with respect to each other, a rst rigid frame membensupporting one of said elements, a second rigid frame member supporting the other element, a pair of elastic frame members extending substantially in parallel between said rigid frame members and integral with said frame members, and means for adjusting said elastic frame members with respect to said rigid frame members for eiecting the speclfled relative adjustment between said pair of elements.
  • a pair of elements requiring predetermined separation and parallelism with respect to each other, a first rigid frame member supporting one of said elements, a second rigid frame member supporting the other element, rst and second elastic members integrally connected to said rigid frame I members, a third elastic frame member integral with said first rigid frame member, means for adjustable flexing said third elastic trame member for correcting for parallelism between said elements, and further means for adjustably exing said rst and elastic frame members for varying the separation between said elements.
  • vall frame members are comprised in an integral moulded frame structure.
  • a rst frame member a second frame member, an elastic frame member integral with said rst and second frame members, adjusting means for varying the relative positions of said rst and second frame members by flexing said elastic frame member, and
