TOWER.

SPECIFICATION forming part of Letters :Patent No. 603,01 1, dated April 26, 1898.

Application iilcd .Tune 21, 1897. Serial No. 641,541. (No model.)

To @ZZ whom t may concern:

Be it known that I, HERBERT H. MAooMnnn, a citizen of the United States, residing at Kendallville, in the county of Noble, in the State of Indiana, have invented cert-ain new and useful Improvements in Towers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form part of this specication.

lily invention relates to improvements in metal towers.

The object of my invention is to provide a supporting metallic tower of novel construction especially adapted to support watertanks and like structures and so arranged that its component parts and sections can be readily assembled or taken apart for shipment or storage and when erected forms a strong and substantial structure with an economy of material.

My invention consists of an eight-post metallic supporting-tower for water-tanks and the like, the uprights of which are formed of four-part sections rigidly connected end to end and properly braced by'struts and tierods.

The novel feature of my invention consists in the construction of the four-part sectional uprights or supporting-posts and the manner of securely uniting the said parts.

In the accompanying drawings similar reference-numerals indicate like parts in the several views.

Figure l is a side elevation of my i mproved eight-post tower, showing the relative arrangement ot the struts and tie-rods. Fig. 2 is a horizontal sectional view of one ot' the supporting tower posts or uprights on the line a; a; ot Fig. 1, showing the manner of securing the end of the tie-rods. Fig. 3 is a cross-section of one of the tower-posts on the line A A of Fig. 1, showing the stiffening-plates between the angle-irons of the four-part uprights. Fig. 4: is an enlarged detail of the meeting ends of the upright sections,;show ing the means for rigidly connecting the same. Fig. 5 is a horizontal sectional view of the same on the line Y Y of Fig. 4. Fig. 6 is a plan view of the pillow-blocks or base-cast ings. Fig. 7 is a side elevation of one of the pillow-blocks.

The tower posts or uprights 1, four in number, of any proper height, are arranged in rectangular form and upon a proper slant or angle, and intermediate said posts, upon each side of the tower, are arranged the supporting posts or nprights 2, also l.tour in number. These uprights 1 and 2 are identical in construction, are rigidly mounted upon the pillow-blocks 7, Fig. 1, and are surmounted by a plurality of metallic girders or cross-beams 4f, preferably three in number, upon which the tank or other liquid-holding receptacle is properly secured.

The pillow-blocks 7, Fig. 6, have their upper faces provided with the vertically-rising but slightly-inclined integral cross-flanges 9, to

the sides of which the lower extremities of the tower-posts are riveted or bolted, Fig. 1. In two diagonal angles of said iianges are arranged the integral upright L-shaped lugs 11, adapted to support the corresponding portions of the fourpart posts. The outer one of the remaining diagonal angles of said anges has an integral upright l' -shaped lug 10, adapted to support the outer portion of said post, the lug 10 being somewhat higher than the said lugs 11, because of the inclination of the tower-posts. For the same reason no lug is provided for the inner part of said posts. These blocks 7 have a perforation 12 for a proper anchor-pin. The blocks 8 are similar in construction to the blocks 7, but are secured to said posts in an inverted position, Fig. 1. The uprights 1 and 2 are formed of sections preferably about twenty feet in length, and each section is formed of four L- shaped angle-irons, preferably of steel, arranged out of contact and with their angles adjacent, Fig. 5, and are then rigidly united by means of the internal horizontal crossplates 14 and 15, Fig. 3. The plates 14 and 15 are arranged one above the other and are placed about every three or four feet throughout the length of said sections and are rigidly held in position bythe rivets 1G, Fig. 3, which pass through said plat-es and the corresponding opposite .flanges of said angle-irons 13.

By this means the sections are made Very firm and strong with a minimum amount oi' material, thereby preserving the greatest degree of lightness consistent with the requisite rigidity and stability. The sections thus constructed are connected end to end by four vertical rectangular longitudinal plates 20, Figs. 4t and 5, arranged, as shown, of a thickness equal to the distance between the adjacent angle-irons and of a sufficient length to afford proper security and rigidity at the joint. The plates 20 are rigidly secured in place by the holding-bolts 2l, which pass through said plates laterally and also through theadjacent sides ot' said angle-irons. The fourpart sectional uprights thus constructed and arranged are rigidly connected laterally by the horizontal angle-iron strutsS, rigidly riv eted or bolted to the said angle-irons, the members of each part being arranged in parallel relation, as shown in Fig. 2, and the said struts being of sufficient number to secure the desired rigidity and strength.

The tower is further braced and strengthened against lateral pressure or torsional strain by the diagonal tie-rods 5, Whose meeting ends are united by proper turnbuckles 6 in a welbunderstood manner. The outer ends of these tierods are provided with an integral head 1S, Fig. 2, longitudinally apertured for a proper securing-bolt which is mounted in the adjacent sides of said angle.

irons.

My improved tower, preferably of steel, thus constructed has great strength and rigidity, with no Waste of material, can be erected without special skill, has small liability for need of repairs, and can be readily taken apart for shipment or storage.

Having thus described my invention and the manner of employing the saine, what I desire to secure by Letters Patent isl. In a metallic tower, the pillow-blocks provided on their upper faces with the integral i cross-danges 9, the angular lugs 1l, and the angular lugs 10, substantially as shown.

2. In a metallic tower, the pillow-block 7 having formed integral therewith the vertically-risin g but sli ghtly-inclined cross-Han ges 9, the upright angular lugs 11, and the angular lug l0, combined with the sectional uprights formed of four L-shaped an gle-irons which are bolted to the cross-f1anges 9, substantially as described.

3. In a metallic tower, the pillow-blocks provided with cross-nan ges 9,the uprights formed of four L-shaped angle-irons which are separated from each other and connected by the cross-plates 14 and l5, the longitudinal connecting plates 20, bolts which are passed through the uprights and the plates, and the tie-rods having their lower ends placed between tWo of the L-shaped sections of the uprights and secured in position by means of bolts, combined with the struts 3 secured horizontally to the uprights, and the beams 4, the parts being arranged and constructed, substantially as shown and described.

Signed by me, at Kendallville, Indiana, this 17th day of June, 1897.
