Description

PATENTED JULY 4, 1905.
T. S. GLOVER.
CALIPERS.
APPLICATION FILED 0016,1904.
Quiet-mug set with a Vernier-gage and then used on work where a micrometer or Vernier-gage could not be'used,
The construction and operation of my invention will be readily understood from the 'n'eceding description and accompanying drawings without a more extended explanation.
From the foregoing it Will be obvious that my improved adjusting means may be applied to various types of bipod measuring instruments such as COHIDZLSSOS, dividers, drawing instruments, and all kind of caliperi1'1gtools'-- and that any adjustments made are positive, accurate, and not liable to accidental movement. The adjusting devices are out of the way and the tool is properly balai'icml and easily handled owing to the central disposition of the adjusting-nut.
Various changes in the shape, proportions, and minor details of construction may be resorted to without departing from the principle or sacrificing any ol the advantages of this invention.
Having thus described my invention, what 1 claim as new, and desire to secure by Letters Patent, is
it. A measuring instrument comprising legs toggle-lewrs pivoted at one ol their ends to the opposite legs ol the instrument, a studblocl; to which the opposite ends of said toggles are pivoted, an adjusting-serew swiveled in the sttul-bloek, a spool-shaped nut through which the adjusting-scrcw passes, the instrument-legs, said legs having recesses at their upper ends to engage said nut, and a spring for holding said together, simstantially as described.
2. A bipod instrument comprisinglegshaving outwardlycurved upper portions and straight upper ends, said ends having grooved and recessed inner faces and beveled terminal ends, curved toggle-levers pivoted to the opposite sides 01 the legs at their curved upper portions, a stud-block pivotally connecting the inner ends of said toggle-levers, an adjusting-screw swiveled in said stud-block and extending up between the grooved upper-ends ol the legs, a nut seated in the recesses in said logs, the screw passing through the nut, a bowed spring spanning the legs and connected thereto, and a tubular extension on the spring to accommodate the projecting upper end of the adjusting-serew, substantially as described.
'lhe herein-ileseribed caliper, con'iprising the legs, the toggle-levers pivoted to said legs, the stud-block to which the opposite ends of said toggle-levers are pivoted, an adjusting screw, said legs having recessed upper ends, a spool-shaped nut engaged by said recessed upper ends of the legs, and said adjustingscrew passing through said nut, an indicatorplale pro imting laterally from one ol' the legs, a pointer pivoted to one of the legs and provided with an index-linger adapted to traverse said plate, a spring secured to one of the legs and bearing upon the pointer, and a stop for said pointer, substantially as described.
in testimony whereoll havehereunto my hand in presence of two subscrilrving witnesses.
