Calipers.
f Patented April 12, v1859.
UNITED STATES PATENT OFFICE.
FAYETTE GOULD, 0F HUNTINGTON, NEW YORK.
CALIPERS.
Specification of Letters Patent No. 23,564, dated April 12, 1859.
Toall whom t may concern:
Be it known that I, Fiixnrrn GOULD, of Huntington, in the county of Suffolk and State of New York, have invented a new and useful Improvement in Calipers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in whichm Figure l, is a face or side view of my invention. Fig. 2, is a transverse section of ditto, taken in the line zr, a', Fig. l.
Similar letters of reference indicate corresponding parts in the two figures.
This invention relates to an improvement in that class of calipers in which a sliding jaw is placed on a graduated bar having a stationary jaw at one end.
The object of the invention is to obtain by means of these implements a more accli late measurement than usual, and the i11- vention consists in having an index attached to the sliding aw and operated by a rack and pinion, and the movement of the jaw, so as to give very minute fractional parts of an inch or other divisions marked on the bar on which the movable or sliding jaw works.
To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.
A, represents a metal bar which is graduated at one side into inch divisions. This bar has a stationary jaw B, attached to one end of it, and a jaw C, of similar form is fitted on the bar A, and allowed to slide thereon, said jaw being prevented -from casually moving on the bar in consequence of a spring a, which is fitted in the sliding jaw B, and allowed to bear against the inner side of bar A.
The jaws B, C, are simply metal projecw tions extending at right angles froi bar A, the inner or face edges of the jaws being parallel with each other, or, if desiredthey may be curved similar to the llegs of jointed calipers.
To the sliding jaw B, at its upper part and in front of the graduated side of bar A, a dial plate D, is attached. This plate is graduated into l128 equal divisions. In the outer edge of the bar A, a sunken rack Z), is fitted, and into this rack a pinion c, gears, said pinion being on a shaft el, which passes through the center of the dial plate D, and has an index c, on one end which traverses over the dial plate D.
The size of the pinion c, is such that when the sliding jaw B, is moved one inch on the bar A, the index e, will make ust one revolution on the dial plate D, it being understood that the pinion c, is rotated by the movement of the sliding jaw.
From the above description it will be seen that the index c, registers the fractional parts of inches and on account of the scope obtained for graduation of said fractional parts ver;7 minute measurements may be obtained, viz., to the 128th part of an inch, and if a large dial plate is employed, more minute divisions may be obtained. The dial plate should be covered with a stout crystal f, in order to protect the index e.
Although the several parts are described as being of metal, still a wooden bar and jaws maybe used, faced with metal. An entire metal implement however would be preferable.
I do not claim a stationary and sliding jaw fitted to a graduated bar, for such device has been previously used for. measuring and is well known; but, having thus described my invention,
That I claim as new and desire to secure by Letters Patent, is,
In combination with the jaws B, C, and graduated bar A, the dial plate and index c, the latter being actuated by the pinion c, and rack b, substantially as and for the purpose set forth.
