SPECIFICATION forming part of Letters IPatent No. 896,974, dated January 29, 18189.

Application filed May 29, 1888. Serial No. 275,420. (No model.)

To all whom, it may concern:

Be it known that I, EDWARD BARRATH, of

Cincinnati, in the county of Hamilton and State of. Ohio, have invented certain new and useful Improvements in (foal-Ilods, oil? which the following is a specification.

The object of my invention is to provide a novel eoal-hod or similar vessel wherein the to the accompanying drawings, making a part of this specification, inwhich Figure 1 is a central. vertical section of a coal-hod embodying my invention. Fig. 2 is a similar view of a modification thereof. Fig. 3 is a diagram re n'esenting the first step of bonding the metal; Fig. l, a similar view showing the second step; Fig. 5, a similar view showing the third step, and Fig. (i a similar view showing another step in the process of. con.- structing the coal-hod.

In the drawings, the letter A indicates the conical-shaped body of the bucket, 15 the baserim, and the bottom. The preferred form of construction is .to make the double hooks o Z) of the scam in the base-rim l3, and the oporation of constructing a seam is as follows: The metal from which the rim is formed is first bent inward and upward, into the shape shown in Fig. 3, by means of a spinning tool or by dies. It is then bent into the shape shown in Fig. l. The lower edge of the body A is then placed on the ledge (Z in the manner shown in Fig. Pressure then applied to the parts i and (Z by means of dies or other 40 b, resting on. the bottom 0, as shown in Fig. 1.

Thus the bucket is formed with a doublehooked seam, a b, in the upper hook, I), of which the bottom G rests, and in the lower one, a, of which the flange c of the body A rests. compression of the double hooks a b. This is the preferred method of uniting the parts together. It is evident that the form shown in Fig. 2 could be made by forming the metal of the body A with the double hooks a I), as described with reference to the base-rim 13. The bottom (I is shown slightly depressed or concave, so as to stiffen the bottom and prevent the vilnfation of the metal, and thus increase the wear of the bed.

What I claim is A coal-hod or similar metallic vessel, consisting of the body A, the rim B, and the bottom 0, each made out of a single piece of metal and united by a double-hooked seam formed of a double hook integral with one of the parts, into the two hooks of which double hook the other parts are respectively inserted and clamped, substantially as shown and de scribed. 4

In testimony whereof I have hereunto set my hand.

EIHVARI) BARRATH.
