METALLIC LANDMAR'K FOR EVIDENCING SURVEYS OF LAND.
SPECIFICATION forming part of Letters Patent No. 427,394, dated May 6, 1890.
Application filed April 1, 1890.
To all whom it may concern:
Be it known that I, JOHN P. BROWN, a citizen of the United States, residing; at Rising Sun, in the county of Ohio and State of Indiana, have invented a new and useful Metallic Landmark for Evidencing Surveys of Land, of which the following is a specification.
Myinvention relates to certain new an d useful improvements in posts or landmarks for the use of surveyors in surveying land; and it has for its object the production of a post which shall be of. comparatively small cost and effective for the purpose for which it is designed.
' To this end my invention consists of the details of construction hereinafter fully described, and pointed out in the claim concluding this specification.
In the accompanying drawings, Figure 1 shows my improved post in side elevation, with a portion of the bodybroken away. Fig. 2 is a similar View showing the post provided with a triangular-shaped head or cap. Figs. 3 and 4 are side elevations showing the cap bearin g various survey marks or records; and Fig. 5 is a vertical section through the body of the post, showing the position of the head or cap when placed therein.
For the bodyof my post or landmark I employ metal tubing, which may be the gaspiping in common use. This is driven into the ground to the desired depth, and I find that as the earth enters into the pipe, as well as presses around it, the pipe is firmly held against displacement and forms a durable and permanent mark for the corner of the sec- Serial No. 346,226. (No model.)
tion or quarter-section of land which it is designed to designate. Into the upper end of this pipe I- place a cap, which is made in the form of a bolt, the cylindrical portion fitting within the pipe or body of the post and its head extending out beyond the circumferenee. any desired shape, and different shapes may be employed to mark the corners of half or quarter sections of land. Upon the sides of the cap the surveyor makes the survey marks or characters necessary to designate the 10- cality or point which such post designates and its distance and direction from others, and upon its edges notches may be made designatin g the distance of the township-lines. In the top of the cap I provide a depression of suflicient depth to receive the end of a surveyors rod and enable the rodman to hold such rod in an erect vertical position, thus providing for the use of same as a sight from which the surveyor can take a line or direction.
Havingthus described my invention, what I claim as new, and desire to secure by Letters Patent, is
A corner-post or surveyors mark, comprising a hollow cylindrical body and a cap therefor adapted to fit therein provided with a derod, substantially as and for the purposes set forth.
