LAURENCE WEST WYlVLAN, OAKLAND, CALIFORNIA, ASSIGNOR TO CALIFORNIA CORRUGATED C ULVERT COMPANY, OF OAKLAND, CALIFORNIA, A CORPORATION OF CALIFORNIA.

To all whom it may concern:

Be it known that I, LAURENCE Wnsr WYMAN, a citizen of the United States, residing at Oakland, in the county of "Alameda and State of California, have invented certain new and useful Improvements in Sheet- Metal Tanks, of which the following is a specification.

My invention relates to the class of sheetmetal tanks, troughs, flumes, pipes and other sheet-metal structures which require an endclosure member.

My invention consists in the novel end connection which I shall hereinafter fully describe.

Though my invention is applicable to any sheet-metal structure of the class mentioned, it is especially adapted for stocktanks or troughs, either for water or food, and in this connection it is found particularly useful for hog-troughs, in that it is sanitary, durable, and economical in manufacture.

Referring to the accompanying drawings:

Figure l is a cross section of my improved trough.

Fig. 2 is a longitudinal section, broken, on

the line 2 2 of Fig. 1.

Fig. 3 is a top plan view, broken. Figs. 4 and 5 are detail views showing a slight modification of the top-lugs of thje end members.

1 is the sheet-metal body of the trough, bent in transverse section to any desired shape.

The end edges of the body 1 are beaded at 2, the bead being of any suitable shape. It may be circular or it may be arcuate, the latter being here shown.

8 are the end-closure-members of the trough. These are of metal, in practice castmetal, and each has on its inner face, near its border, a flange 4:, the outer face of which is formed into a seat 5 complementing the bead 2 of the end edges .of the body 1.

The end-members 3 are formed below with feet 6, and at their tops they have inwardly projecting perforated lugs 7.

The end-members 3 are fitted to and over lap the end edges of the body 1, and their flanges 4 enter the body, the seats 5 of said flanges fitting and embracing the beads 2 of the body, as seen clearly in Fig. 2.

Specification of Letters Patent.

Patented Oct. 28, 1919.

. Application filed September 12, 1918. Serial No. 253,714,

If desired, a suitable packing, such as a coating of heavy paint, or paste, or mineral rubber, may be placed in the joint between the seat 5 and the bead 2, but to avoid confusion-in the drawing, I have not deemed it necessary to show this.

When the end-members 3 are in place, the clamping-members which are here shown as rods 8 are fitted to the beads 2 by laying them in the concave exterior surfaces of said beads, the ends of the rods passing through the perforated lugs 7 of the endmembers; and said end receive the nuts 9.

It will now be seen that by tightening up the nuts 9, the rods 8 will clamp the beads 2 against the seats 5 of the flanges 4 of the end-members 3, and thus make a secure and tight joint between the cast-iron end and the body of the trough.

10 are reinforcing rods in the side edges of the trough body. These may or may not be used.

The shapes of the interfitting parts and the materials used may be Varied without departing from the invention.

By the connection which I have herein described, the cast-iron ends are satisfactorily fastened to the sheet-metal body without the use of rivets or solder, and they may be removed conveniently if required to more perfectly clean the trough.

As shown in Figs. 4 and 5, the perforated top-lugs 7 of the end members may assume the shape of separate cross plates 11.

I claim l. Sheet-metal tanks comprising a bodymember, the end edge of which is beaded; an end-closure-member having a portion complementing and interengagingly fitting the bead of the body-member; and a clampino-member for tightening the complementary parts of the body-member and the endclosure-member together.

2. Sheet-metal tanks comprising a bodymember the end edge of which is beaded; an end-closure-member having a flange on its inner side with a face complementing and interengagingly fitting the bead of the body-member; and a clamping-member for tightening the bead of the body-member against the face of the end-member flange.

3. Sheet-metal tanks comprising a bodymember the end edge of which is provided with a bead; an end-closure-member having on its inner side a flange adapted to enter the end of the bodymember, the face of said flange corresponding to and interengagingly fitting the exterior of the bead of said bodymember; and a clamping-member fitted to the bead for tightening it in the flange.

i. Sheet-metal tanks comprising a bodymember the end edge of which is provided With a bead; an end-closure-member having a portion complementing and interengagingly fitting the head of the body-member, and having also perforated members at its top; a clamping-member for tightening the Copies of this patent may be obtained for complementary parts of the b0dy-1ne1nber and the end-closure-member together, said clamping-member passing" through the perforated top members of the end-closuremember; and nuts on the ends of the clamping-member.

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

LAURENCE WEST WYMAN.
