SPECIFICATION forming part of Letters Patent No. 232,972, dated October 5, 1880;

To all whom it may concern.- I

Be it known that I, JOHN O.'IsAAo,of Oornwall on the Hudson, in the county of Orange and State of New York, have invented a new and Improved Corner Stone for Boundary- Lines, of which the following is a specification.

In field-work, in surveying, much trouble and inconvenience are experienced from the imperfeet and unsatisfactory marking of cornerstones by incompetent persons, and from the lack of a uniform character or distinctive type of stones, many of them so nearly resembling the stones of the locality that they are liable to be overlooked or lost sight of, and serious troubles and misunderstandings have, itis well known, often arisen because of the obliteration of the inscriptions thereon byatmospheric influences or by evil-designed persons.

The object of this invention is to provide a device by means of which theseinconveuiences may be almost entirely avoided.

Figure 1 is a vertical elevation of the device with parts broken away to exhibit other parts. Fig. 2 is a cross-section of the same on line 90 00, Fig. 1. Fig. 3 is a cross-section of the same on line 3 y, Fig. 1. Fig. 4 is a plan of the same.

Similar letters of reference indicate correspondin g parts.

In the drawings, A represents the body of the post or corner-stone provided with a socket or bore, a, extending longitudinally and centrally throughoutits length, and provided with a cap, B, and a shoe, 0, that are held in their respective positions by means of the rod D, that passes through said post or cornerstone A and the said cap and shoe BO, respectively.

That portion of the stone A that is designed to extend above the ground G has, preferably, four faces,as shown,each of which is provided with a vertical dovetailed mortise, a, for containing the types or letter-blocks E and quads F, that are correspondingly dovetailed, that they may more securely hold in place.

The cap B is provided with a central mortise, b, which is beveled or dovetailed on one face, as shown, and extends through said cap, and said cap B is also recessed on the under face, as shown at 0, whereby said cap is fitted over and upon the top of the body of the stone A, and the upper ends of the types or blocks E and the quads F, to hold them, respectively,

in place, while the flange of said capB extends horizontally in every direction beyond the faces of the types or blocks E, and thereby greatly protects them from atmospheric influences.

The shoe 0 also has a central mortise, 61, extending entirely through it, and in its inner face two or more sockets, f, into which, when the parts are together in position, the corresponding studs 9, that project from the body Aof the stone, tit and prevent the turning of the said shoe (J.

The rod 1) is formed into a half dovetail tenou at its top, as shown, while on the opposite face, near its lower extremity, it is cut away, so as to form a square shoulder, 7c, and the said rod D is extended well below the shoe (J, so as to give greater stability to the device when set in position.

H represents the locking-wedge of the device.

In assembling the parts of this device the rod D is passed down through the body A and the shoe G,which latter is set in position with its sockets f holding the studs 9 of the body A; then said rod D is turned so thatits shoulder shall engage on the under face of the shoe 0, as shown in the drawings; then the desired letters and quads are set in place in the mortises a, and the cap B is then set on top of the said bodyA in such a position that the dovetail tenon of the top of the rod D shall be in contact with the beveled face of the mortise b, as shown, while the head of the rod D shall be flush with or a little below the face of the cap B. The locking wedge H is then driven firmly in the mortise a, in the rear of the head of the rod D and flush or a little below the face of the cap B, so as to hold all of said parts immovably together, and so that no part of the device can be removed without fracture of the part removed or of some other part. a

If desired, molten lead orother substance may be poured into the mortise a,about the locking-wedge H and head of rod D, to effectually seal them against the effects of the atmosphere.

This post and all its parts are preferably constructed of iron; but I do not confine myself to the kind of material used in the construction, nor do I confine myself to the precise construction ot'parts and the securing them together, as herein shown, as modifications may be made in these points without departing' from my invention.

Havingthus described my invention, I claim as new and desire to secure by Letters Patent- 1. As an improved article of manufacture, a corner-post constructed substantially as herein shown and described, consisting of the body A, provided with bore a and mortises a a, mortised cap and shocB (3, respectively, shouldered and dovetailed rod D, and locking-Wedge H, as set forth.

'2. The combination, with the body A of a corner-post, provided with letters or blocks E, of the cap B, extending laterally beyond said letters or blocks, substantially as herein shown and described, whereby said letters are protected from atmosphericinfluences, as set forth.
