Application iled September l2, 1894. Serial No. 522,815. (N o model.)

city of St. Louis, in the State of Missouri,`

have invented a new and useful Tower, of whlch the following is a specification.

My invention relates to improvements in towers whose tops are supported upon posts and the objects of my improvements are to economize space, material and labor. I attain these objects by the structure illustrated in the accompanying drawings, in which- Figure l is a View in perspectiveof a tower embodying my invention, and a water tank supported thereby. Fig. 2 is a top view of the cap, and cross beams thereon, and illustrates, in the lower half of the view the manner in which I prefer to lay the joists upon said beams, where the tower is designed to support a water tank. Fig. 3 is in part a cross section of my tower along the line 3-3 of Fig. l and in part, a view in perspective' showing the arrangements of posts. Fig. 4 is a view looking from below of the shoe used to connect the cross beams together at the center ofthe tower. Fig. 5 represents a side view of said shoe and of central supports beneath it the superstructure being shown in cross section. Fig. 6 is a modification showing a circular cap.

Similar letters refer to similar parts throughout the several views.

A, (Figs. l, 2 and 6) represents the cap of the tower. In Figs. 1 and2 it is represented as octagonal in shape but it may be a polygon having any number of sides more than four, or may be formed in the shape of a circle as it is shown in Fig. 6. The shape which I pre-V fer -is that of an Octagon.

B, B, B, B, B, B, B, B, are posts used to support the cap. They are preferably placed at equal distances apart and where the cap is polygonal in shape, and the posts equal in number to the sides of thevcap, as I prefer they should be, each post preferably comes beneath the center of one of the sides of the cap as shown in Fig. l. The posts incline inward from bottom to top as represented in Figs. l and 3. They preferably rest upon lfoundations ofconcrete or masonry, yand are held in place at their lower ends by dowel Y pins or other suitable means.

O, O, C, C, C, C, C, C, (Figs. l and 3) represent foundations for the posts, and c, c, c, c, c, (Fig. l) represent dowel pins.

D, D, D, D, D, D, D, D, (Figs. l and 3) are braces placed between the posts, directly above the foundation C.

E, E, E, E, E, E, E, E, (Figs. l and 3) represent braces placed between the posts preferably about midway betweenthe cap, and the foundations. y

F, F, F, F, F, F, F, F, (Figs. l and 3) are tie rods designed to hold the posts together and prevent spreading. They are equal in number to the posts. Two are connected to each post one running from it to the second post from it on one side and the other to the second post from iton the other side.

G, G, G, G, (Figs. l, 3 and 5) are posts preferably four in number springing from the inner sides of posts, B, B, B, B, and supporting the center of the superstructure. Their upper ends bear against the shoe H (Figs. 2, 4. and 5) by which the cross beams resting directly upon the cap, rest and are connected centrally. I connect said central supports with the posts B by scarf joints G', G', (Fig.

l.) In the drawings (Fig. l) the bands by which the two posts are united are lettered g. Where the tower is very high the posts B if made of wood are usually spliced and in such cases-I prefer to splice them about the center as shown in Fig. 1, where the splice is lettered B and, where the central supports G are used the bands g, should pass entirely around the posts and they then serve to hold the two portions of the posts B, together as well as to hold the central supports G in place. l

I, I, (Fig. 3) are cross ties which I prefer to use where the central supports G form a part of my structure and are especially designed to strengthen those portions of the structure bearing the weight of the central support. They connect opposite posts. The ties F,F are shown represented as passing through the posts with which they are connected. This is not essential and in some casesis undesirable. Any well known method of connecting them with the posts may be adopted.

Upon the cap VA, in my towerfI prefer to form the floor for the water tank or other thing to be supported substantially as fol- IOO lows: Across the cap I lay two beams K, K', at right angles to each other and mortise them where they cross each other so as to leave their upper surfaces flush with each other, and to their under sides I attach the shoe H (Figs. 2, 4). I prefer to so place these beams that they will each rest upon the cap directly over posts in the manner shown in Figs. l and 6 and they preferably extend some distance beyond the sides of the cap and I prefer that the cap piece should be of such a size as to make its sides come at about the center of gravity of that portion of the weight of the tank or other thing intended to be supported lying between its center and circumference, supporting the center of the tank or other thing supported to be exactly at the center of the tower. In addition to the cross beams K, K', I prefer to use four other beams L, L, L, L, (Figs. 2, 4 and 6) whose inner ends rest upon the shoe II to which they are attached and whose outer ends are supported by the cap A just as the other beams are. Upon the beams K, K and L, I arrange the joists M (Fig. 2) and where the thing to be supported is a water tank I prefer to allow the tank to rest upon said joists.

In some cases it is desirable to extend the flooring and the beams which support it, so far beyond the sides of the cap A, that it is best to provide supports for the ends of the beams K and K', and in such cases, I prefer to use the braces O (Fig. l) which are preferably four in number. Their lower ends pref erably rest upon the same posts which support the central supports Gr, which said central supports tend to brace said posts against an inward pressure. They may be attached to the posts B by means of the scarf joints 0, O, O, Fig. 1, and preferably support the ends of the beams K and K which are slightly stronger than the beams L, though they may be arranged to support the latter beam ad vantageously instead of the former or to su pport the ends of all if desired. In the drawings (Fig. 1) my tower is represented, supporting a water tank P which is one of the purposes for which I consider it most useful. The manner in which the tank is preferably arranged on the tower where my tower is used to support a tank is shown in the drawings.

` The word circularly is not used in this specification in its strict sense. When used with reference to the arrangement of the supporting posts it is intended to mean that they are arranged substantially as they would be if arranged around the edge of a circle or a polygon having five or more sides, or even an ellipse.

The posts, G, instead of being supported by the posts B may extend to the ground or the foundations upon which the posts B rest.

In my improved tower braces may be substituted for the ties F, where ties F are substituted for the braces D.

I claiml. The combination of a cap, supporting posts `more than four in number, circularly arranged and sloping outward from top to bottom, and ties for binding said posts together, equal in number to the posts; each post having a tie running from it to the second post from it on each side, substantially as described.

2.
