POST FOR FENCING OR OTHER PURPOSES.

SPECIFICATION forming part of Letters Patent No. 709,217, dated September 16, 1902 Application filed January 8.1902. Serial No. 88,865. (No model.)

T0 at whom it may concern.-

Be it known that 1, ROBERT HENRY GUTH- RIE,farmer, of the township of South Dumfries, in the county of Brant, in theProvince of Ontario and Dominion of Canada, have invented new and useful Improvements in Posts fol-Fencing or other Purposes; and I do hereby declare that the following is a full,

clear, and exact description of the same.

The ob 'ect of m invention is to )rovidea.

post of great strength and one that will be practically free from the decay caused by the action of the elements and more particularly that of the earth in which its lower portion may be embedded.

It consists, generally speaking, of a post or pole of wood strengthened by truss rods or Wires running from its lower end to a pointthat would be some little distance above the ground were the post set therein in the usual way, the structurethus formed being then wholly or partially incased in a body of cement moldedto any desired shape.

Referring. to the accompanying drawings which are made a part hereof, and in which similar letters refer to similar parts through out, Figure 1 is anelevation of a finished post of the type having a complete outer A portion of this outer covering is broken away to show the inner post and the truss-wires attached thereto. Fig. 2 is an elevation of a post or pole in t which only a partial casing of cement is used.

. Fig. 3

is a view of a post before the outer casing of cement has been applied. Fig. 4is a fence-bracket used in posts of the type shown in Fig. 1.

In Fig. 3 (also shown in Figs. 1 and 2) Bis a wooden post of suit-able length and for fencing purposes of much smaller diameter than that ordinarily used.

D D, Fig. 3, (also shown in Fig. 2,) are clips secured about the center post B at suitable distances apart, to which are attached the ends of the truss-wires G O, 1, 2, and 3.

While for brevity I may continue to use theexpressiou' truss-wires throughout this description, it will be understood that at times quite heavy rods might be used to advantage, it will also be understood that I do not confine myself to the method just described for securing the ends of the trusswires, as in many cases an ordinary staple driven into the post would serve to hold them, while in others the ends of the truss-wires themselves could be passed about the post and secured. The truss-wires O C then pass over the supporting blocks or fulcrunls E E, Figs. 1 and 3, said blocks being placed at the point in the length of the post at which the greatest strain is likely to cotneusually at or near the ground-line. 'lhese truss-wires may be used on all sidesof the post; but usually two are foundto be the most suitable number, these being placed on the post at right angles to the direction in which the fence I'llllS.

\Vhen the type of post sought to he made is such as shown in Fig. l, to the center post B at suitable distances along its length are attached the fence-brackets, (designated by the letter F in Figs. 1 and 3, and also shown in Fig. 4.) These are made of iron and are pointed, so that they may be securely driven into the center post B. and they are of a length sufficient to allow of the hooked portion projecting beyond the outer coating of cement in the finished post.

Q, Figs. 1, 3, and 4, is a disk formed upon the bracket at an intermediate point in its length. This disk gages the depth to which the bracket maybe driven into the center post and insures the proper length projecting. It will be understood that these brackets might be made to screw into the center post or they might be threaded and made to pass entirely through it, being secured by a nut on the opposite side thereof. I have shown them, however, in their-simplest form. These brackets, as shown, are intended to be used when the resulting fence is to be of wire, the hooks being closed after the fence-wires have been placed therein, as shown at F I in Fig. 1. In case the fence were to be of any material other than wire the hooked portion of the brackets would require to be made of a shape suitable for attaching thereto.

When the resulting post is to be such as shown in Fig. 1, the structure just described and fully shown in Fig. 3 is placed within a mold of any suitable design, which is then 'filled with cement, completely incasing the this purpose.

hooked portions of the fence-brackets, (designated by the letter F in Figs. 1 and 3.)-

The cement is then allowed to harden, when the post is removed from themold. The material I have found most suitable for this purpose is composed of one part of Portland cement to three or four parts of good sharp sand, these being well mixed with sufficient water to secure plasticity.

The post shown in Fig. 2 is one in which only a partial casing of cement is used. For this style of, post the structure shown in Fig. 3 is also used, the fence-brackets being, how ever, omitted, as the center post being ex posed from the ground up any style of fence maybe attached thereto in the usual manner. Also in this style the symmetry of the post would be much enhanced by providing as shown at N in Fig. 2, a portion of the.

outer casing being shown broken away for The cement when placed about the post enters into this groove, thus preventing moisture from passing down between the center post and the outer casing of cement. As an additional safeguard a shield of galvanized iron or other sheet metal may be .used to cover the upper portion of the cement casing. This shield would be secured to the center post above the cement and would pass down over the latter sufficiently far to shed any moisture passing down from above. This is shown as X in Fig. 2.

While describing Fig. 2 as a fence-post, it

will be understood that the same method of' treatment would be applicable to posts or poles for many other purposes, such as flagpoles, telegraph and telephone poles, &c.

Having thus fully described my said invention, what .I'claim as new, and desire to secure by Letters Patent, is-

1. In a fence-post, the combination-of an outer casing of cement, a post embedded therein, truss-wires attached to said post and running lengthwise of the same from end to end thereof, a series of brackets secured to i said post and extending ontthrough said casing of cement, the outer ends of said brackets being provided with means whereby a fence may be attached thereto, substantially as described.

2. In a fence-post, the combination of an outer casing of cement, a post embedded therein, truss-wires attached to said post and running lengthwise of the same from end to end thereof, a series of brackets secured to said post and extending out through said casing of cement, the outer ends of said brackets being provided with hooks adapted to be closed when fencing-wires have been placed therein, substantially as described.

3. In a post for fencing or other purposes, the combination of an outer casing of cement, a post set therein, truss-wires attached to said post and running lengthwise'ofthe same from the bottom upward, said casing of cement enveloping the lower portion of said post and the truss-wires attached, and extending upward to a point intermediate the ends of said post, all substantially as described.

4. In a post for fencing or other purposes, the combination of an outer casingof cement, a post set therein, truss-wires attached to said post and running'lengthwise of the same from the bottom upward, said casing of cement enveloping the lower portion of said post and the truss-wires attached and extending upward to a point intermediate the ends of said post, said post havinga groove about it circumferentially at the uppermost point reached by said casing of cement, said casing of cement covering said groove and enteringinto it for the purpose of producing a water-tight joint between said post and said casing of cement, substantially as described.

5. In a post forfencing or other purposes, the combination of an outer casing of cement, a post set therein, truss-wires attached to said post and running lengthwise of the same from the bottom upward, said casing of cement enveloping the lower portion of said post and the truss wires attached, andextending upward to a point intermediate the ends of said post, the upper portion of said cement casing ICC being protected by a covering of sheet metal,

all substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
