RANGE-Roo. 'Y
'To all whom it may concern.-
' Be it known that I, NATHANIEL LAFON, a
- @citizen of the United States, residing at Red l Jacket, in the county of Mingoand State of West Virginia, have invented new and useful j Im rovements in Range-Rods, of which the fol owing is a specification. 5
This'invention relates to engineering instruments, and particularly to lrange-rods, the-object'of theinvention being to'provide a range-rod support having special and novel means whereby the range-rod after` its rimary adjustment or setting may be shi ted lbodily in a horizontal plane in any direction,
.KIS
which the tripod-legs '3 are rectly in line with a 'given point.
With the above general objects in view the invention consistsy in the nov'el construction, combination, and arrangement of parts, as hereinafter fully described, illustrated,l kand In the accompanying drawings, Figure 1 is aplan view o the instrument embodyin the present invention. Fig. 2 is ay vertica diametrical section through the same, taken in line kwith the range-rod. Fig. 3 is 1a detail tripod-legs. Fig. 4 is a detailed view of the range-rod.
`Like reference-numerals designate corre- 'sponding parts in all the figures of the drawlngs. f
The range-rod support resembles an ordinary surveying-tripod and embodies a centrally-apertured ltripod-head plate 1, provi`ded w1th downwardly-projecting lu s 2, to
nected at the points 4. [The cad-plate 1` is provided with a large central a erture 5 and upon the flatupper surface of t ehead-plate 1 is placed an adjustable caplate 6, also flat and provided with a centra aperture 7,
vas shown in Figs. land 2.
which corresponds with the central aperture 5 of the head-plate 1, as clearly shown 1n Fig. 2.
The cap-plate 6 is provided at ldiametricv ally opposite points with pivots 8, upon the inner ends of whichis` supported a swivelring 9. `'lhisring carries at diametrically opposite points ivots 10, which are arranged midway etween vthe which engage at their inner en s with trunnions 11 projecting laterally from avertically-disposed range-rod 12, kwhich passes through the apertures of the plates 1 and-6,

so as to position the range-rod vertically di-` lcross-section through the joint of one of. thev ivotal y conpivots 8 and 4 y Connected to the lower end of the rangerod 12.` is a weight consisting of a hollow cylinder 18, iilled with a weighty substance 14,
such as mercury. lThe lower end of the cyl` inder 13 is exteriorly threaded to receive aAv cap-nut 15, and said vnut is provided with an opening 16, extending therethrough to receive and retain the cord 17 of a plumb-bob 18. The u per end of the cord 17 is knotted or provide with an enlargement 19.to prevent its escape from the opening 16.

the i headlate is provided y with upstandini lstudolts 20, and the cap-plate is provide with relatively large openingsv 21, (indicated .l
in dotted linesin Fig. 1,) through which said stud-bolts ass, the said openin s being con are loosened, which allows the cap-plate 6 to be shifted to bring the range-rod to the exact position required, after which the clamplgoiviv.
nuts are tightened. The plumb-bobk isy found of considerable ,convenience in progyerly locating and positioning the ran e-ro ;v but if not articularly desired it may` e disconnects the plumb-bob to the of the range-rod.l j,
