Description
@eine ma femm @time LVORY A. HURD, 0F BOSTON, MASSACHUSETTS.
Letters Patent No. 66,239, dated July 2, 1867.
IMPROVED DEPTH-GAUGE.
TO ALL WHOM IT MAY CONCERN:
Be ittknown that I, IVORY A. HURD, oi`- Boston, in the county of Suffolk, and State of Massachusetts, have invented certain new and useful improvements in Depth-Gauges and I do hereby declare that the following is a full and exact description thereof', reference being had to the accompanying drawings, and to' the lettersof reference marked thereon. v i
The nature of' my invention consists in constructing an improved depth-gauge by combining with the wings or guards B B a screw-spindle, A, and a check-nut, E.
To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and use. In the drawings- Figure 1 is an elevation.
`Figure 2, a vertical section.
Figure 3 is a plan of my improved gauge.
I first construct it of any suitable metal B B, iig. 1, oi some convenient size and shape, as, for instance, that represented in the drawings. In the centre of this, between C and D, the metal is cut away to admitl the spindle A, as shown in fig. 1. At the n this collet the spindle A passes freely. At the lower edge of the wng-piecea collet, D, is securely attached. This collet D forms a nut, through which the spindle A screws. Just above this collet is the check-nut E. The spindle A has a milled knob, K, at its top.
, To use this gauge the chock-nut E is loosened, and the spindle A is screwed up or down, as the case may be, until its point extends the desired distance below the wing-piece. Thercheck-nut E is then screwed hard against the collet D, which action `will hold the spindle A firmly in place.
This gauge may be used for measuring the depth of" holes drill thickness of plates or pieces of' metal worked upon a planing machine.
Having thus described my invention, I will proceed to set fort-h lny claim. and, desire to secure by Letters Patent of the United States, is-
The combination, as well as the arrangement, of the wing-piece B B with the spindle A, check-nut E, and collet D. i
ed on lathe-work, or for measuring the What I claim as my invention,
IVORY A. HURD. Witnesses A. HUN Benni', vFRAM( G. PARKER.
