APPARATUS FOR LEVELING AND SQUARING STONE.

SPECIFICATION forming part of Letters Patent No. 397,286, dated February 5, 1889.

Application tiled November 20, 1888. Serial No. 291,380. (No model.) Patented in Germany September 29, 1887, No. 48,761, and in France November 11, 1887, No. 186,925.

To all whom it 711.11g (ZUHMJ'IL:

Be it known that l, MAX lll-iNsEL, of Christianstadt on Bober, Kingdom of Prussia, and Empire of Germany, have invented certain new and useful improvements in Apparatus for Leveling and Squaring Stones, (for which Letters Patent were granted to me in Germany, No. -:L.3,7t;l, dated September 20, 1887, and in France, No. 1Sti,925, dated November 1.1, 1887,) of which the following is a specification.

The object of my invention is to provide a new and improved apparatus of simple construction to be used for leveling and squaring stones either in blocks or in thequarry, which apparatus can also be used for locating points in making stat-nary.

The invention consists in the combination, with a standard having a tripod-base, of a 1'0- tative sleeve on said standard, a horizontallysliding rule in said sleeve, and a vertically sliding rule in the end of the horizontal rule; and the invention also consists in the combination of parts and details, as will be fully described and set forth hereinafter, and pointed out in the claims.

In the accompanying drawings, Figure l is a front elevation of my improved apparatus for leveling and squaring stones. Fig. 2 is an end view of the same. Fig. 3 is a sectional plan view, parts being broken out. Fig. 4 is a detail face view of the lower end of the vertical rule. Fig. 5 is an edge view of the same. Fig. 6 is a side view of my improved apparatus, showing the manner in which it is used for fixing an inclined surface on a block of stone. Fig. 7 is a side view of the same, showing the manner in which it is used for fixing a level surface in a quarry. Fig. 8 is a side view of my improved apparatus and a block of stone, showing the manner of using the same in locating points. Fig. 9 represents a model from which the points are taken.

Similar letters of reference indicate corresponding parts.

The base A is provided with three legs, A, in the lower end of each of which an adj usting-screw, A is held, the lower ends of which screws are pointed. On the standard B 011 the base A a sleeve, C, is mounted to turn,

which can be locked in place by a binding screw, 0. Said sleeve 0 is provided with laterally-projecting head D, and in the same a rule or straight-edge, E, is mounted to slide horizontallythat is, in a plane at right angles to that of the standard B. One end of said rule E is supported by guide-pieces F on the upper end of an inclined arm, F, projecting from a sleeve or collar, 3r, mounted loosely on the standard B and resting on the base A. The upper end of the rod F is braced by a rod, G, fastened to the sleeve G. The head D is also provided with a binding-screw, H,

for locking the rule in place. On one end of the rule E a guide-box, K, is fixed, which is provided with slots for guiding the straightedge or rule L at right angles to the straightedge or rule E, said box being provided with suitable binding-screws, K, for locking the rule L in place. The rule L is provided at its lower erd with an adjustable pointed leg, N, and with a small spirit-level, M.

Below the rule E a circular disk, R, is held horizontally on the sleeve 0, the upper surface of said disk being provided with protractor-subdivisions, so as to facilitate adj usting the rule at any desired angle in the horizontal plane.

The apparatus is used in the following manner: hen it is desired to obtain a level surface on a block of stone, the instrument is placed upon said stone, and by means of the screws A in the base is so adjusted that the standard B stands vertically and the rule E is horizontal, which is determined in the usual manner by a spirit-level. The rule L is at right angles to the rule E, and is so adjusted that the point of its adjustable leg N will be at the desired level or plane. sleeve 0 on the shaft B, or by shifting the rule or straight-edge E longitudi nallyin said sleeve, any number of points can be fixed on the stone, all of which points are on the same level. All that is necessary is to cut away the stone between said points, care being taken not to destroy the points found.

Fig. (3 shows the method of finding points in the manner described, the standard B being at an inclination; but in all cases the rule E must be at right angles to the standard B, and

By turning the I the rule L at right angles to the rule E and parallel with the standard 13.

Fig. 7 shows a method of usin my improved implement in a quarry for the purpose of finding a true and level surface, the manner of using; it being prz'letieally the same as that described above.

Figs. 8 and 9 show the manner of using the implement in making statuary. The model is plaeed in a eertain position, and certain points a (t on said'model are determined. Their distanee from the end of the rule E is measured by means of the rule L. At; said points (I, (1/ on the bloek ol stone the stone is cut away nnt il points are found which are the same distanee from the end of the rule E as are the eorresponding points on the model. In this manner all the neeessnry {mints ol' the model can be fixed on a blocdc of stone, whereby the making ol statuary is greatly laeilitated.
