SURVEYINGJINSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 445,886, dated February 3, 1891.

Application filed July 3 1 8 90.

To @ZZ whom it may concern:

Be it known that I, JOSHUA NEVEL GEE, a citizen of the United States, residing at Pleasant Grove, in the county of Lunenburg and State of Virginia, have invented certain new and useful Improvements in Surveying-Instruments; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto whichit appertains to make and use the same.

This invention relates to measuring-machines for surveying roads, farms, lands, the., and which will record the measurements, the degrees, and the level above the sea.

The improvement consists of the novel features and the combination and peculiar construction of the parts, which hereinafter will be more fully described and claimed, and which are shown in the annexed drawings, in which- Figure l is a perspective view, parts being broken away, of a machine embodying my invention. Fig. 2 is a detail view showing the means for returning the printing-rollers to the starting-point. Fig. 3 is a detail view showing the spring for holding the printingroller frames down. Fig. e is a detail view through type-bar. Fig. 5 is a detail view of a portion of the printing-roller, showing the relative positions of the plungers and the type-bars thereto. Fig. 6 is a detail side view of the lower portion of the machine, showing the appliances for operating the printingroller from a wheel of the vehicle.

The vertically-sliding frames A B, which carry the printing-rollers C and D, are mounted in the frame, which is composed of the vertical standards E and the c1'oss-bare,which unites the standards E at their upper ends. Each of the printing-rollers C and D is provided with a series of numbers around its periphery from one to any required number. These rollers have gear-wheels c and d, respectively, which mesh with corresponding gear-wheels f f on the printing-roller F, which is arranged beneath the printing-rollers C and D and is journaled in the standard E. The table G, arranged about on a Serial No. 357,844 (Model.)

level with the meeting faces of the rollers C, D, and F, is provided with a suitable opening to permit the upper portion of the printing-roller F to project therethrough. The guide I-I is secured at its ends to the table, and a recess 7L is provided between its under side and the top of the table for the passage of the strip (not shown) on which the record is kept. The operating-bar I is adapted to engage with one of the gear-wheels at the end of the roller F, as f, and move the said roller forward the space of one tooth or more at each forward movement thereof. The end of the bar I is held in engagement with the gearwheel f by the spring 2T. The bar I is guided in its movement by working between the stops fi".

The lever .I for transmitting motion from a suitable part ot the vehicle to which the device is applied is connected at one end with the bar I and is returned to a normal or starting position by the spring j. The opposite end of lever J in the present instance is arranged to be engaged by the eccentric 7.; on the wheel K of the vehicle.

The type-bars L, held in suitable guides on the table, are arranged to be moved over. the printing-roller F in the direction of motion of the vehicle, and are provided at regular intervals with spring-actuated type r, ranging from one to sixty, more or less, as required. The springs Z are arranged to press on the type-bars L and prevent them from moving too rapidly or going past points when moved forward or backward to the required position. The vertical bars M have plungers m at their lower ends, which when said bars M are actuated engage with the type r.

The type-bars may be moved over the printing-roller in any convenient manner; but the preferable way is indicated in Fig. l, which shows them provided with a rack-bar a, which meshes with a pinion h on the shaft b', that is journaled in suitable bearings on the table G.

The type-bars will be provided insufficient number' to contain all the degrees ofthe compass and the fractional parts thereotaud the numbers from l up to the highest peak in the world. Obviously the more numbers on each bar the fewer wil-l be the number of the bars and the changing of the same will be the less frequent. v

The type 'l' are set in apertures in the bars and the spring r is fastened at one end to the bar and its other end is constructed to en` gage with the type r, so as to hold the same in an operative position and return it to va normal position after being depressed, as will be readily comprehended, in the type-barsL and canse the same to press upon thestrip and print thereon. Each'of these bars Mis connected with the frames A and Bby means of the levers N and the links n. The frames are held at their lower position by the spring O, which is fastened between its ends to the middle standard E, and which has its free ends engaging with' pins o that extend from` the proper type comes beneath the plungerl m,fwhen the bar M is depressed and prints the level on' the strip that may be indicated by the instrument Q., Reference is had to the compass for'determinin g thedegree when the same is printed on the strip` by 'moving' the type-bar L to the proper position and depressing the bar M inthe manner hereinbefore stated. The "vehicle is' Vpropelled yover theM ground,rand, at each revolution ofthe driving-wheel' Kfthe bar I will be moved'forwardA and turn the printing-rollers C, D, and F a proper distance, so as to effect a printingof the numerals thereon on' the strip which passes between the rollersC, D, and F. Vhen thev direction of the vehicle is changed, the degree y'will be indicated on the compass'and will beprinted'on the 'strip by moving the bar L and depressing the bar M, as hereinbefore stated Should the 'level change, the same will be made known bythe instrument Q, when the height' may be printed on the strip by placing the type-bar L in proper position and depressing the bar M, as previously described. E ach of 'the printing-rollersC and Dis provided with a spring S, one end of which is attached to theA journal or other portion of the roller, and the other end being conn'ecte'dvith the. frame in which the said roller is journaled. Obviously as the roller is turned forward the tension on the spring is'increased.l VWhen the frame'to which the roller is journaled is elevated by depressing the bar M, the gear-wheel on said roller will be disengaged from the gear-Wheel on the printing-roller F, the spring` will return -tlie said'roller to the zero or starting-point, the roller beinglimited in its motion by the stop f. As hereinloefore stated, the type rare acted on by a spring r', the parts being so constructed that they spring will return the type to a normal position after being depressed. In the preferred form the type r is tted loosely in the opening in the type-bar, and is recessed in its sides near its printing end to receive the free end of the spring r', which latter? is constructed to enter the said recesses in the sides' of the type. Vhen the plunger is depressed, it projects the type directly beneath it, and after the plunger is released lthe spring r returns the type to a normal position. f f
