IMPROVEMENTIN SURVEYING-INSTRUMENTS.

Specification forming part of Letters Patent No. 181,451 dated August 22, 1876 application filed l I June-24,1876.

I and State of Pennsylvania, have invented a new and valuable Improvement in Surveying- Instruments; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings,

" making-a part of this specification, and to the signed to be seated in the. bearings a, being =confined-therein by means of clips 0, which are journaled usually'to the branches of the wyeletters and figures of reference marked thereon.

Figure 1 of the drawings is a'representation of a front view of this invention, with leveltelescope in the wyes. Fig. 2 is 'a-front view, with cylinder-axis int-he wyes, and level-telescope vertically arranged. Fig. 3'is an end view, showing the graduated wheel. Figs. 4, 5, 6, 7, and 8 are details.

This invention has relation to surveyingfinstruments; and it consists in the construction and novel arrangement, in combination, of a transit and Y-level, forming a right-angular instrument; also, in the novel combination, with said instrument, of an axis-piece, whereby the level-telescope can be arranged to sweep in a vertical plane; and, finally, in the construction and novel arrangement of the frame and axis connection, as hereinafter fully shown and described.

The object of thisinvention is to provide a single instrument which will serve efficiently in place of two instruments-that is to say, the Y-level and transit, now separately used by surveyorsand to so arrange the same instrument that it will be especially: adapted for work in mining districts, and other places where it is necessary at times to sight in the vertical direction. In the accompanying drawings, the letter designates the upper plate or limb, which carries the compass B and standards which support the telescopes. The standards may be made entire, or in two or more parts, one portion, 0, extending upward from the plate, and terminating at its upper end in a circular bearin g, a, being similar to the wye of an engineers level, the other portion, D, extending above the Wye-bearing, being usually about twice its height. It may form a portion of the Wye-- standard, being extended upward from one of its branches, as illustrated in the drawings;

'or it may be attached to the plate by an independent foot. tire standard in one piece.

It is preferred to make the en- --At the upper end of-the arms D are the journal-seats b,.f0r the journals of the axis E of the transit-telescope F. These journal-seats may be made in the usual manner, to allow the transit-telescope to turn readily in the vertical plane.

G indicates the level-telescope, which is debearings,.oppositethe transit-arms D, as indicated at din the drawings, and may be secured to said transit-arms by suitable pins 6; or the clips may be secured to the opposite branches of the wye-bearin gs in the usual manner, when these are made separate. When seated in the .wye-bearings, thelevel telescope is designed to have a direction at right angles with that of the transit-telescope, said directions being referred to a horizontal plane. i B designates the compass, and K represents the level, which is'attached t0 the under side of the telescope G in the ordinary manner, having the usual adjusting devices at the ends. This instrument is designed to serve every purpose for which two instruments-the engineers level and the engineers transit-are now commonly employed, and possesses further advantages with reference to right-angularmeasurements, derived from the position of the two telescopes and their common relation to the compass. l 1

It is evident that the transit-telescope may also be provided with a level, if desired, in the usual manner. 1

, For certain astronomical observations and mining operations a different adjustment of the' level-telescope is provided for, by means of the axis-cylinder L. This piece is designed to be sufficiently long to be seated in the bearings a of the wyes, its ends being provided with journals g, so that it may be readily revolved in said bearings.

At one end there is attached to the cylinder a graduated circle or wheel, N, the edge of which, when the cylinder is turned, moves upon an arc-scale, S, or vernier, which is attached to the frame or one of the standards,

in a position exterior to the latter,as shown in .the drawings. A screw-rod, It, extends through the hollow center of the axis cylinder, being provided with a milled head, I, at one end thereof. 7

- At theother end of thecylinder the leveltelescope is designed to be attachedin the vertical plane. The attachment or connection may be made in several modes;

In the drawings, the telescope is repre tion q of the wheel fits around a projecting neck of the cylinder-head, into the central opening of which the nut ris received, and

the telescope secured in position by screwing the end of the axis-rod k intosaid nut. This arrangement is designed to enable the telescope to sweep a vertical plane when turned around on the journals of the axis-cylinder, and to serve an important, purpose in sighting perpendicularly up or down. It also enables the surveyor to read off any angle of elevation or depression on the divided circle S.

In order to strengthen the limb or plate A, in order to make it sufficiently strong tobear the double weight of the telescopes, a bar, Z, may be extended diametrically across the same from standard to standard, and may support the latteraa V I am aware that the mode of building this instrument may be varied in some particulars by persons skilled in the art, and, therefore, the invention is not limited to the precise construction herein shown and described.

-VVhat I claim as my invention, and desire to secure by Letters Patent, is-

l. The combined Y- level and transit, having two telescopes centrallytand diametrically arranged above the compass, at right angles to each other, and the Y-bearings below the extended journal-seat arms, which carry the transit-telescope, substantially as specified.

2. The combination, with a surveying-transit, of a side telescope, sweeping in a vertical plane parallel with that of the transit -telescope, for perpendicular sighting and measuring angles of depression and elevation, substantially as specified.-

3. The telescope standards, consisting of y the portions O, extending upward fromthe base-plate, and terminating at their upper ends in bearings a, and theportions D, extending above said bearings, to receive the journals of the transit-telescope, substantially as specified.

4. The axis-piece adapted to revolve in the wyes, forming the journallof the level-telescope, when arranged in the vertical plane, substantially as specified. i

5. The combination, with a wye axis piece having a graduated end wheel, of the leveltelescope and the divided are, substantially as specified.

6. The level-telescope, provided with aside attachment, m, in combination with the axispiece and fastening=rod ubstantially as speci-. fied. I r

. 7. A surveyinginstrument having doubleseated standards diametrically opposite "each other, on each side of, and extending above, the transit-compass, formounting the .level and transit telescopes, substantially as s'pe'ci fied.

8. A Y- level havingan axis attachment, L, to form a journal for the level-telescope, at right angles with the cylindercase of said telescope, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
