LEVELlNG-TOOL.

SPEQIFIGATION forming part of Letters Patent No. 598,101, dated, February 1, 1898.

Application iiled February 27, 1897i Serial No. 626,414. (No model.)

To @ZZ whom, t may concern:

Be it known that I, JOHN P. KANE, a citizen of the United States of America, residing at Dawson ,inthe county of Fayette and State of Pennsylvania, have invented certain new and useful Improvements in Leveling-Tools, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to leveling-tools; and it has `for its object to provide a new and useful tool of this character specially adapted for the use of masons.

To this end the invention contemplates the construction of a leveling-tool having simple and efficient means for indicating the exact pitch or degree that the wall or other object upon which the tool may be used is out of plumb, and also means for positively indicatin g the proper angle of batter-work in masonry or gable-work in building.

While the invention has for its object the construction of a leveling-toolintended to accomplish the results referred to, still another feature of the invention is to construct the tool in such a manner that the several parts thereof may be readily taken apart and placed together in a comparatively small compass, which parts can also be readily assembled when it is desired to usethe tool or instrument.

Nith these and other objects in view,which will readily appear as the nature of the invention is better understood the same consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed.

In the drawings, Figure l is a perspective view of a leveling-tool constructed in accordance with this invention,showing the pitch-bar supported in position for use. Fig. 2 is a longtudinal sectionalview of a portion of the toolbody, showing the detachable connection between the contiguous ends of the body-sec tions. Fig. 3 is a cross-sectional view of the tool-body at the point where the indicating device is housed. Fig. aisa detail sectional View on the line e et of Fig. 3. Fig. 5 is a detail in perspective of the end portion of the toolbodyprovided with a double hook for the attachment of an ordinary plumb-line.

Referring to the accompanying drawings,

ings or open spaces 3, which serve to materially lighten the body, and the contiguous or meeting ends of said sections have a detachable interlocking connection, which connection consists of short tcnon-pins 4t, projected from the end of one section, and mortise-notches 5, formed in the contiguous end of the adjacent section and receiving the said tenon-pins.

The tenon and mortise connections between the meeting ends of the body-sections 2 serve to maintain these sections in precise alinement, so that the continuity of the tool-body will be preserved while the same is in'use; butto provide for securely fastening the bodysections together to prevent their disengagement there are employed fastening screws or bolts 6, passing through registering openings in the abutting ends of the body-sections and engaging the threaded plates 8, permanently iitted in said abutting ends of the sections, such construction being plainly illustrated in Fig. 2 of the drawings. It will be seen that by the removal of the fastening screws or bolts 6 the several sections of the body may be readily taken apart and coinpactly placed together in a comparatively small compass.

The sectional tool-body l is provided in one of its side edges with acontinuous groove 9, extended longitudinally from end to end thereof and adapted to snugly receive therein aseotional pitch-bar lO. The sectional pitchbar l0 is of the same length as the sectional tool-body l and is formed of a series of duplicate sections 11, havinga detachable interlocking connection l2 at their contiguous ends, it being observed that the pitch-bar is formed of the same number of sections as the tool-body, with the sections of the same length, so that when the pitch-bar is in its folded position and lies flush within the groove 9, forming a seat therefor, the sections of the IOO toolbody and of the pitch-bar Will come apart together and will remain in proper position, so as to be assembled together at the same time Without the necessity of separately assembling the toolbody and the pitchbar sections.

The sectional pitch-bar 10 has a pivotal connection 13 at one end with the tool-body, and at an intermediate point said pitch-bar has an offstanding pin 14, adapted to seat itself in the notch 1,5, formed in one edge of the tool-body and having pivotally connected thereto one end of the longitudinally-slotted brace-bar 16, the longitudinal slot of which receives the saidl screw 17, which provides means for securing the pitch-bar at any ad-V justed angle, as clearly illustrated in Fig. 1 of the drawings.

The tool-body 1 is preferably provided at the side edge, opposite the edge in which the pitch-bar lO is fitted, With inch-graduations, so that the same may be conveniently used as a rule, and at one end the said tool-body is provided With a double hook 18,in which a plumb-line may be secured' when it is desired to use a line of this character in connection with the tool.

The levei or inclination of the tool-body is indicated by means of an indicating device carried by one of the sections 2 of the toolbody, and this indicating device is housed Within a rectangular casing 19. rihe rectangular casing 19 of the indicating device `registers within the opening 3 of one of the end sect-ions 2 of the tool-body, and it is secured in place by means of the screws or similar fasteners 20, passing into the body-section. The rectangular casing 19 is provided Within its opposite ends With skeleton bearing-frames 21, having central bearing-openings 22 and having fitted to the outer sides thereof the dial-plates 23, provided with a series of graduations, preferablysc'aled to one-eighth of an inch. A pointer-shaft 24 is arranged inside of the indicator-casing 19 and is provided With opposite spindle extremities 25, projecting through the bearing-openings 22 and openings in the dial-plates 23 and having fitted thereto the double pointers 26, arranged to oscillate over the outer faces of the dial'- plates and point to the graduations thereon to provide means for indicating the inclination or pitch of the tool. To provide nfor maintaining the necessary vertical` disposi tion of the double pointers 26, the pointer-` i shaft 24 hasconnected therewith between its 1 ends a pendent Weight 27 ,which Weight counterbalances the pointer-shaft and holds the pointers to a proper indicating position.

Ytool will be readily` apparent Without further description, and it Will be understood that various changes in the form, proportion, and

minor details of construction may be resorted to Without departing from the principle or ysacrificing any of the advantages of this invention.

Having thus described my invention,what I claim, and desire to secure by Letters Patent, is- V 1. In a leveling-tool, a straight separable toolbcdy formed of a plurality of duplicate alined sections havin ga detachable interlocking connection at their abutting ends, said body being provided in one side with a continuous groove extendinglongitudinally from end to end thereof, separate fasteners detachably engaging with the interlocked abutting ends of the body-sections, and a folding pitchbar having a pivotal connection at one end with the tool-body and formed of a plurality of alined sections corresponding in number and length to the sections of the tool-body, said pitch-bar being adapted to register flush Within the groove of the tool-body, substantially as set forth.

2. In`a leveling-tool, a straight separable tool-body formed of aplurality of duplicate alined sections detachably connected together at their abutting ends and having openings piercing the same, said body being provided in one side with a continuous groove eXtending from end to end thereof, an indicator device fitted inside of the opening of one of said body-sections, and a folding pitch-bar adapted to register Within the groove of the toolbody and having a plurality of detachablyconnected alined sections corresponding in number and length to thesections of the toolbody, `substantially as set forth.

In testimony whereof I affix my signature in presence of two Witnesses.

JOHN P. KANE.
