Description
UNITED STATES PATENT OFFICE.
MARTIN WILCOX, OF NEW HARTFORD, CONN ECTIOUT.
IMPROVEMENT IN SPlRlTu-LEVELS.
Specification forming part of Letters Patent N0. 178,354, dated June 6, 1876; application filed March 9, 1876.
To all who-m it may concern Be it known that I, MARTIN WILCOX, of New Hartford, in the county of Litchfield and State of Connecticut, have invented a new Improvement in Spirit-Level; and I Ydo hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and `exact description of the same, and which said drawings constitute .A is a level glass-holder, constructed at its tw ends with a lug or ear, a, inclined upon the under side, as shown. Beneath these two ends the adjustable seats d are arranged. These are inclinedupon their upper surfaces, corresponding to the incline of the lugs a, and are slotted, so that the screw e, which is introduced through the ear, and run into the wood, will pass through the slots in the seats, the seats d resting solidly upon the wood below.
To adjust the glass, either of the seats d is forced beneath its respective ear, or drawn therefrom until the bubble indicates the perfeet level. In that condition the screws e are set, thus securing the glass-holder and the seats in place.
The transverse or plumb glass is adjusted and secured in the same manner, save that the inclined ears are formed at one end ofthe glass-holder, and at right angles thereto, as seen in Fig. 2, the same letters in that portion of the drawing indicating the same parts.
The combination, in a spirit-level, of the inclined lug a on the glass-holder, the correspondingly-inclined adjustable seat d, and setscrew e, through both lug and seat, substantially as specified.
MARTIN WILooX.
