JEFFERSON n. HARRY, or DALLAS, TEXAS.

METAL s'roaasn-rnnm Toull whom it may concern:

Be itknown that I, JEFFERSON D. HARRY, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements 1n- Metal Storage-Tanks, of

which the following is a specification.-.

This. invention has relation to metal stor age tanks and particularlyfto knock-down tanks. y

The object of thefmventio n is to provide a tank formed in-several sections or parts and arranged to be assembled in an expeditious andsubstantial manner. 1

Another feature is a particular form of gether and held in permanent relation.

F mally the object of. the invention is to provide a tankof the character described thatjl'will be strong, durable, eflicient, and light in weight, comparatively inexpensive to construct; and one in which the several parts will' not be likely to get out of working I order.

With the abovevand other objects in View, the invention has relation to certain novel featuresof construction and operation, an

example of which is described in this specification andillustrated in the accompanying drawings, wherein: Figure 1 is an elevation of .the tank'assembled, Fig. 2, is a partial vertical section, ig. -3, is a detail of one of the clamps in perspective, and Fig. 4 is a detail in section of a" modified form.

In the drawings, the numeral 1 designates one of-the side sections of the tank, 2 the bottom sections, and 3, the top sections. The

members

4 and 5 are preferablyformed of A The clamps are made in single and double wood to make the section as light as possible, although other suitable material could be used if desired.

Each frame has a panel or innercovering ably fastened to the inner side of the. frame.

be adjusted to draw the members and a tank so assembled that the sections of one course break-joint with those ofthe next ad aoent courses.

The edge. portions or outwardly directed fflanges 7 of one. section are opposed to the corresponding portions of the adjacent sections, and between the sections, a suitable packing, 8 may be disposed both vertically and horizontally. When the sections aredrawn together this packing will be compressed and the liability of the tank leaking reduced to a minimum.- The bottom sections '2, also each have a frame, which however is composed of segmental members 9 connected by cross members 10 at their ends, but said cross members lying in the same plane as the members 9; The bottom sections are of course disposed horizontally and each has such a length as to produce a circular base when the said sections are all in place. Each bottom frame has a covering 11 of sheet metal having downwardly directed flanges 12 embracing the sides of the cross members 10. The sheet metal of the bottom is merely ex tended over the members '9 as shown at the right of Fig. 2. Wherever sections are brought together, the packing 8 is interposed. If a lock-joint is desired between the lowermost sections 1 and the bottom sections, the flanges 7- 0f the lower members. 4 are extended outward and bent up as shown at the left of.Fig. 2. The edge portions 14 of the bottom sheet metal coverings 11 are bent up and about the bent portions of the flanges and a folded sea-m produced. Such an arrangement will not only strongly, connect the bottom and side sections, but provide a water-tight joint.

For holding the sect-ions together, I provide a plurality of clamps. Each clamp comprises two members 15, each having an eye 16 and the adjacent edges of the members overlapping, whereby a bolt 17 passed through the eyes and held by a nut 18 may of a clamp together or permit them to be moved apart.

collar. These clamps are disposed as is best snown in Fi s. 1 and 2, the opposite members either engaging the adjacent members or the adjacent members 4 of the side sections 2 and the segmental members 9 of the bottom sections. lVhen the members are placed in position, the tongues being tapered may be readily inserted between the wood frame members and the sheet metal covering, thus holding each individual member in position on its respective part which it embraces. The double clamp members are used at the intersection of two members 5 and two members 4 or at the intersection of two members 5 and the bottom members 4 and 9. In the double. clamps one of the members 15 as shown in Fig. 3 has an angular collar which embraces the members 5 and ties them together.

The sections 3 at the top of the tank radiate from a center stud 21 and each section has radial members 22 along its edges, extending from the stud. Each section is formed of sheet metal 23 secured to the radial members and turned down at its outer edge to form a segmental flange 2a fitting over and fastened to the upper segmental In Fig. 4 I have shown a modified form,

of tank. This tank is designed for storing crude oil and material which would corrode or injure the sheet metal coverings. The general construction of the tank is the same, the main difference being in a lining 25 of soft metal, as lead which is applied to the inner surface of the sheet metal and the flanged portions of the same.

IVhat I claim is: w

1. A knock-down tank comprising a bottom, a top, a sectional cylindrical body, the sections forming the body each comprising a wooden frame having vertical and horizontal members, and a sheet metal covering having its edge portions bent about the frame, and two part clamps embracing the adjacent members of adjoining sections, the clamps spanning the members transversely.

2. A knock-down tank comprising a bottom, a top, a sectional cylindrical body, the sections forming the body each comprising a wooden frame having vertical and'horizontal members, and a sheet metal covering having its edge portions bent about the frame, two part clamps embracing the adjacent members of adjoining sections, the clamps spanning the members transversely, anda packing interposed between the sections. v

3. A knock-clown tank comprising a bottom formed of sections each having a frame covered with sheet metal bent thereabout, a sectional cylindrical body, the sections of the body each comprising a frame covered with sheet metal bent thereabout, a top formed of sections each comprising sheet metal secured to the side sections and having radial members, and two part metal clamps embracing and extending transversely'of the members of adjoining frames
