Speccationof Letters Patent.

Patented Aug. 4, 1908.

Application filled October 10, 1907. Serial No. 396,820.

To all whom it may concern: Beit known that I, WILLIAM HENRY JONES,

a citizen of the United States, residing at Ru-l gineering connected with an irrigated farm.

The principal object of the invention is to provide a rod of this character which may be used by persons of little experience in engineering work. j

Another object of the invention is to provide a leveling rod which may be conveniently adjusted for any size ditch and which will give cuts or iillsforboth banks and 'bottom at the one reading, so as to dispense with the necessity of figuring.

Another object of the invention is to provide an attachment for a leveling rod by means of which a ditch may be readily cross sectioned. 4 y l With the above and other objects in view, the inventionconsists of the novel features of constructionl and the combination and arrangement of parts hereinafter described and claimed7 and illustrated in the accompanying drawings, in which y Figure 1 is a front elevation of my, improved leveling rod; Fig. 2 is a side elevation of the same; Fig. 3 is a rear elevation; Figs. 4, 5, and 6 are transverse sectional views taken respectively on the planes indicated by the lines 4 4, 5-5 and 6--6 in Fig. 1; and Fig. 7 isa detail` longitudinal section taken on the plane indicated by the line 7-7inFig-3. j, Y

My improved leveling rod-comprisesl a rear or lower section 1 and afront or `u per section 2, which latter-.is adapted to s ide upon the former andv to :be adjustablyv secured thereto by means of a set -screw 3 or an equivalent clamping device arranged preferably at the upper end of the rear section or rod as more clearly shown in Fig`.- 4. In the'sides of the front section orvrod 2y arefformed longitudinal grooves 4 to receive flanges 5 formed on plates 46 secured to the op osite sides of the rod 1 for the purpose of ho dingthe/two rods or sections together in sliding engagement;

At the' lower end of the rod 2 is secured-a U- shaped strap 7 which surrounds and slidably engages the rod 1 for a similar purpose. The downward sliding movement of Athe rod 2 upon the rod 1 is limited by a stop 8 preferably in the form of an angle bracket secured upon the front face of the rod 1 adjacent to its lower end as clearly shown in the drawings. The front rod is graduated upon'its front face'in feet and tenths of feet from a zero point adjacent to its center which point 3 is marked 0, `to its upper and lower ends as clearly shown in Fig. 1, the graduationS upon the upper ortion of said rod being arranged upon the eft hand side of a centrally disposed longitudinal line 9 and the correspondl ing graduations 10 on the lower portion of said rod being arranged upon the right hand side of said line. The rear face of the front rod is graduated in feet and tenths of feet as shown at 11 from its top to its bottom and the corresponding'face ofthe rear rod is similarly graduated as shown at l2 from its bottom to its top.

13 denotes the target which 'is slidably mounted upon the front rod 2 and is adapted to be secured in an adjusted position thereon by a set screw or equivalent clamping .device 14. This set screw is arranged in the center of the lower portion of the target and has its inner end bearing against a Iresilient metal shield or guard plate 15 secured upon the back face of the target for the purpose of protecting the rod 2 from being scratched or marred by the set screw. Said target is in the form of a circular plate having a centrally disposed vertical opening 16 to expose the front face of the rod 2 and side plates or anges 17 which engage the o posite sidesof said'rod 2 and are formed witli ribs 18 which enter and slide in the grooves 4 in said rodas ,more clearly shown in' Figf. 5. The front ladapted'to co-act with the graduations 8, 10

on said rod as hereinafter explained. The said intersecting lines on the front face of the vtarget divides it into quarters, thetwo opposite ones of Whichare preferably colored and 1 in the others are printed Fill and Cut as clearly shown `in Fig. 1.

A'lo enable a :d'tch to be cross sectionedV I provide an attachment in the form of a: supplemental rod 19 which is slidably "adjustab on the target and arranged upon the right hand side of the front rod 2. l also provide upon the right hand side of the upper portion.

of the front face of the rod 2 graduations 24 which' co-act with said rod as presently explained. Said rod 19 is graduated in feet as at 20 from its top to its bottom and it is slidable in a guide sleeve 21 arranged upon the rear face of the target. A set screw or equivalent clamping device 22 is provided in the sleeve for securing the rod 19 in an adjusted position. The graduations 2O on the front face of said rod 19 are exposed upon the front face of the target in a small opening 25 formed in it on one side of the opening 16. If in cross sectioning a ditch, the land over which the ditch is to be constructed is on the side of a hill, or very uneven, the rod may be placed ateach of the side stakes, the target made to aline with the level, and the reading at the top of the small rod 19 will be the exact cut or fill for that point.

The numerous uses to which the device can be put will be readily understood from the foregoing description by one familiar with the devices of this character, but I will describe in detail a few of the uses of the same. Vhen it is desired to level a field, the attachment or rod 19 may be removed by loosening the set screw 22 and sliding it out of its sleeve or guide 21. The target is then set at zero and the lower end of thedevice is placed upon a stake which is driven at a suit* able point. The level having been convenicntly located, the set screw 3 is loosened and the front rod 2 is slid u or down until the target is in line with the evel. Said set screw is then tightened to clamp the front rodupon the rear one. The stake is then marked any elevation, say for instance 2O feet. The rod is then moved to the next stake or station and the set screw 14 is loosened to allow the target to be slid up or down until in line with the level. All readings below 0 are added to the original elevation and all above are subtracted from it and the result is marked on the stake. When it is desired to move the level, the rod is set at the last convenient station, the target is set at O and then alined with the level as above explained. Then continue as before, adding or subtracting from the elevation given on last stake.

When it is desired to cross section a ditch,

say for instance a ditch 2 feet from bottom to top of the bank with a grade of .1 of a foot to 100 feet, set target at O and adjust the rod 19 until its upper end marked 0 is 2 feet above the center of the target. Then select a place from which it is desired to start the ditch and determine what cut or iill is necessary to the bottom of the ditch. For instance, say a cut of 1.5 feet is required, set target to read cut 1.5 feet and then set level at any convenient place. Raise or lower front rod to aline with level, then step oil` 100 feet to next station. Raise front rod .1 foot for the grade, then move target to aline with level. The figures appearing at the center line of target on front rod are marked on center stake for the bottom of the ditch. The figures or graduations 20 on the rod 19 appearing in the opening 25 in the target and those on the right hand. side of the upper portion of the rod 2 opposite the upper or O end of the rod 19 are added and their sum is the distance from center stake at which to drive each side stake. The figures on the left hand. side of the upper portion of the rod 2 opposite the upper or 0 end of the rod 19 are marked on each side stake. Vhen it is desired to move level, set target to read same as -center stake at last station then raise or lower front rod until target is in line with level, and proceed as before.
