SURVEYORS-CHAIN HANDLE.
SPECIFICATION forming part of Letters Patent No. 301,869, dated July 15, 1884.
Application filed May 3, 1884. (No model.) I
To all whom it may concern: K
Be it known that I, GEORGE WV. DioKINsoN, a citizen ofY the United States, residing at Charleston, in the county of Coles, State of Illinois, have invented a new and useful Improved Surveyors-Ohain Handle, of which the following is a specication.
My invention relates to an improved handle to be attached to one or both ends of a surveyors chain or measuring-line.
The object of my improvement is to avoid, in the measuring of distances in surveying lands, mistakes arising from the tally-pins out of a true perpendicular, as hereinafter described. I accomplish the above-mentioned obj ect by means of the device illustrated in the accompanying` drawings.
Figure l is a side elevation oi' my device.
' Fig. 2 is a plan.
a is a handle, having in one side notches b b, adapted to receive sidewise a tally-pin, c, such as ordinarily used by surveyors.
d d are lugs equidistant from notches b b, and projecting outward from the handle to receive the edge of a staff, as shown in dotted lines, the purpose being to apply the handle accurately in line with either a tally-pin or a stad, as may be required.
e is an arm formed integral with handle a, and projecting therefrom at a right angle with the line of notches b. j
f is a spirit-level secured to the upper side of arm e, one end being adjustable relatively to the arm by means of screw-washers g g.
7L is a hook adapted to receive the ring on the end of the chain or measuring-line Z. Said hook is secured to arm e in such a manner as to be adjustable toward or from the line of :notches b. As shown, the hook has a shank passing through lugs l v2 on the arm, and terminating in a screw, j, on which are screw- Washers 7c k.
- In operation one of my improved handles is attached by means of the hook'h to each end of the chain or measuring-line, the distance from the end ofthe chain to the center oi' the point of starting, the edge of the staff resting against the inside of lugs d, or the pin resting in the notches b, and the staff or pin is plumbed by means of the spirit`level f. The person carrying the other end of the measuring-line applies a tally-pin to the notches b. in the handle at his end of the line, and holding the pin plumb, as indicated by the spirit-level f, sticks the pin in the ground, thus accurately measuring the distance between the two points.
I claim as my inventionl. As an article of manufacture, a terminal handle for a measuring-line, consisting of a handle having notches or projecting lugs, whereby it may be accurately applied to and in line with a staff or tally-pin, an arm at a right angle to said handle, a spirit-level on said arm, and means for connecting said arm to the end of a measuring-line, all combined substantially as and for the purpose specified.
2. Handle @,having notches b Z1, arm e, spirit-level f, and adjustable hook h, all coinbined substantially as and for the purpose specified.
3. Handle a., having notchesb b and lugs d d, arm e, level f, and hook 7L, all combined substantially as and for the purpose specified.
