character that will indicate the angle of the.
surface against which the level is placed, from the horizontal.
A further object of the invention is to provide an extremely simple and inexpensive device of this character that will be ac curate and reliable, and will be formed of a few parts that will.not easily get out of order.
.lvith the ab ve objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modificatidns may be made in the minor details of construction within the scope of the appended claim. In the accompanying drawing illustrating this invention :Figure l is a front elevation of the level. Fig. 2 is a cross sectional view taken on the line 22 of Fig. 1. Fig. 3 is a fragmentary longitudinal sectional view with parts removed showing the removable cap for facilitating access to the interior of the level. Fig. t is a detail perspective view of the two piece shaft. Fig. 5 is a detail perspective view of the weight and its attaching means. Fig. 6 is. a detail perspective view of one of the pointers and its attaching means.
Referring now tothe'drawing in which like characters of reference designate similar parts, 10 indicates the body of the level, which has the usual straight edge 11. The bodvis formed with a central enlargement 12 through which there is formed a cylindrical opening 13, the enlargement pro]ec ting beyond the upper edge of the body in semi-circular form as shown. The central enlargement 12 is provided with a longtudin'al slot in which is removably mounted a closure 14 so that access to the interior of the opening 13 may be had. At each end of the opening there is a glass dlSk, as shown t 15and 16, such disks having the outer edges beveled as shown at 17 to lit against beveled shoulders 18 formed to project inwardly of the outer edges of the circular opening 13. These disks are formed with central conical sockets 19 to receive the coni-' :al ends of a two-piece shaft 20 that is formed square in cross section. the sections of the shaft being joined together by a substantially square sleeve 21 which receives said sections, and carries set screws 22 which rigidly secure the sections together and holdthe shaft in such length as to confine the disks 15 and 1G snugly in place. Upon loosening the set screws the sections of the shaft may be telescoped into the sleeve to withdraw the siiaft and also the disks through the edge of the enlargement 12 upon moval of the section 14.- thereof.
The sleeve 21 is equipped with an anchor-.
shaped weight 25-3 that performs the function of a plumb bob. gFixedly attached to the square ends of the shaft are pointers 2t and each being equipped at the base with a sleeve 26 of substantially. square cross section, the-ire being aset screw 27 carried by the sleeve and engagin against the shaft to hold the pointer in placei- Arranged on opposit ,i
which are seated i gro' ties ,in the interior wall of the cylin ri dal J pening 14:, these dials each having a cent ic}: iopeniiig 30 which receives the shaft. The ti ii s may be marked i .l ll 1th scales indicating dellgil es and fractional A level including a body having an en--- larged intermediate portion provided with a transverse cylindrical passage therethrough and having a longitudinal slot therein communicating with thepassage, a removable closure for said slot, a shoulder at each end of the passage, glass disks closing the ends ofsaid passage, 2. contractible s es of the weight; are dials28 and 29 lthe btripheral edges of against said. shoulders, a depending Weight upon said haft, pointers on the shaft, and
shaft. journaled at its end in said disks bensathsaid slot aild holding said disks ture, in the presehceof two witnesses. CHRISTIAN -C.'ZARS.'-
