LEVELING AND PLUMBING INSTRUMENT.

Specification of Letters Patent.

Patented Oct. 24-, 1911.

Application filed April 19, 1911. Serial No. 622,107.

T 0 all wh m it may concern.

Be it known that I, Lnonmu) B. VVORDEN, a citizen of the United States, residing at Penn Yan, in the county of Yates and State of New York, have invented a new and useful Leveling and Plumbing Instrument, of which the following is a specification.

My invention relates to improvements in leveling and plumbing instruments.

The invention has for its object to provide for readily and conveniently ascertaining the required pitch or angle in any given piece of work where this may be wanted.

Further objects are also to provide a leveling instrument in connection with the pitch determining member, and to carry out these ends in a simple, effective and inexpensive manner.

The invention consists of certain instrumentalities and features substantially as hereinafter fully disclosed and defined by the claims.

In the accompanying drawing illustrating the preferred embodiment of my invention wherein it will be understood various changes and modifications may be made as relates to the construction and arrangement of the details of the parts without departingfrom the spirit of my invention: Figure 1 is a side or face view of the invention as adjusted for the horizontal, the index registering with the initial graduation or mark. Fig. 2 is a similar view of the device with a portion thereof broken away and other parts in section, disclosing more especially the cam of the indexcarrying member or pin and its receiving slot, also the arcuate ide-slot for the guidepin or stud of the splrit-level carrying member. Fig. 3 is a sectional plan view of the same, the section being produced just below the spirit glass. Fig. 4 1s a vertical or transverse section taken about centrally through the device.

In carrying out my invention I suitably secure preferably to a bar plate 1 arallel upstanding plates or supports 2 having lateral bottom-edge extensions 2 by suitable fastenings, as screws or rivets passing through saidextensions, said base plate in turn being secured in practice, to a straighted 0 member, not shown.

suitably edgewisedisposed plate or member 3 is arranged to have movement between the plates or supports 2, it being pivotally supported in re atively elevated position, upon a suitable pivot or pin 4, which may, in practice, be simply a stub-scrcw, passed through registering apertures 4 in said plates, which apertures may be duplicated as at 4-" for obvious reasons. Said plate or member 3 carries upon its upper edge, at the ends tubular formations, sleeves, or sockets 5 for the reception, or insertion thereinto, of the ends of a spirit-glass G of the well-known type, said SPlIlt-gltlSS being frictionally held in place as will be readily appreciated.

An axial stud or member 7 which has its hearings in alining apertures 8 in the upstanding plates or supports 2, a short distance above the lower edges thereof, has fixed about centrally thereof a cam 9 playing or received within a slot 10 produced in the pivoted plate or member 3 bearing the spirit glass or leveling member, said cam engaging the edges or Walls of said slot. Said axial stud or member carries an indexmember or pointer 11 arranged to play over a graduated quadrant 12 formed by suitably scribing the usual degree-indicating lines or marks upon the outer surface of one of the lateral upstanding plates or supports 2, as

clearly disclosed by Fig. 1.

In the spirit-glass or level bearing or carrying member 3 is an arcuate slot 13 extending in a general inclined direction, which receives a stud or pin 14 from one of the upstanding plates 2 for limiting or controlling the tilting or oscillating movement of the member 3 while being used, which stud or pin may be a stub-screw in practice.

It is apparent that, as the straight-edge member above noted is suitably applied to the object or piece of work, where it is required to ascertain a given pitch or an le of inclination, this will be indicated wit the movement of the index or pointer 11 carried by the axial member 7, playing above the graduations 12 as the axial member is moved or actuated by the engagement of the cam 9 with the walls of the slot 10 of the level or spirit-glass carrying member 3 in conforming to the horizontal, as is apparent. Any degree of inclination, or pitc may be indicated by the use of this instrument, included from the initial point to forty-five digress.

This instrument, it will be observed, 1s extremely simple, readv of operation, efl'ective and accurate in action and inexpensive of manufacture, while the spirit-glass may be used as a leveling instrument alone, as is readily apparent.

1. A device of the character described, including a supporting member, a graduated member attached thereto, a member carrying a spirit-glass, said spirit-glass carrying member and said graduated member having pivotal connection, and an axial member carried by said spirit-glass carrying member and itself provided with an index registering with the graduations of said graduated member, said axial member also carrying a cam engaging said spirit-glass carrying member.

2. A device of the character described, including a supporting member, parallel spaced-apart members attached to said supporting member, one of said parallel members being graduated, a member carrying a spirit-glass and having pivotal connection with, and arranged intermediate said parallel members and an axial member carried by said parallel members and having an index registering with the graduations of the graduate member, said axial member also being provided with a cam engaging said spirit-glass carrying member.

3. A device of the character described, including a supporting member, parallel spaced-apart members attached to said supporting member, one of said parallel members being graduated, a member carrying a spirit-glass and arranged intermediate, and
