GOAL HOD. i No. 382,989. Patented May 15, 1888.

UNITED STATES PATENT OEErcE.

EDWARD BARRATH, OF CINGINNAT, OHIO, ASSIGNOR TO VICTOR E. KNEOHT, OF SAME PLACE.

SPECIFICATION forming part of Letters Patent o, 382,939, dated May l5, 1838.

Application tiled February 23, 1888. Serial No. 264.949.

To @ZZ whom, it may concerne Be it known that I, EDWARD BARBATE, a resident of Cincinnati, in the county of Hamilton and State of Ohio, haveinvented certain new and useful Improvements in GoalHods, of which the following is a specification.

The object of my invention is to make the shell of a coal-hod out of one piece of metal having a crimped bottom.

Another object of my invention is to form the crimped bottom by the vcompression of a cone made to project upward into the hod, so that the crimp will not be straightened out by the weight in the hod.

The invention herein described is carried out by means of the dies shown in Letters Patent No. 378,755, granted my assignee, Victor E. Knecht, February 27, 1888, and by process described in Letters Patent granted my said assignee of same date, No. 878,754, to which reference is herein made of various details of construction.

In the accompanying drawings, Figure 1 represents the blank from which the body and bottom of the hod is made. Fig. 2 represents the iirst step of bending the blank into shape. Fig. 3 is a central section of the hod bent into shape ready for crimping. Fig. 4 is a similar section representing the cone crimped and the shell in position ready to be attached to the base, which is shown in its proper relative position. Fig. 6 is a similar section ofthe completed hod.

1 represents the shell of the hod.

2 represents the portion of the blank from which the bottom is made.

3 represents notches cut upon either edge of the bending line 4 of the blank, so as to allow the corner-pieces 5 of the cone portion of the hod to be bent within the shell portion opposite point (i, as shown in Figs. 1 and 3, so as to allow the cone to be formed within the shell in the manner shown in Fig. 3.

In order to form the cone 2 the metal is creased on the bending line 4 from the slitted corners 3 by any suitable tool, and the cone portion is bent to the position shown in Fig. 2. The blank will then be bent by drawing (No model.)

the edges and 8 together, which are lapped or seamed together in the ordinary mode for coal-hods.

It is not necessary to seam-joint the cone other than the natural lap of the metal. The next step in the formation of the liod is to compress the cone into the crimped form shown in Fig. 4. I prefer to perform this operation as described in the patents above referred to.

The inner shapingdie for crimping should be made of sufficient size and shape to enter the shell of the hod and reduce the cone.

In Fig. 4, 9 represents the crimped portion, which projects up a sufficient distance within the shell to form a V shape at the peripheral base of the shell. 10 represents the base, which is provided with an offset, ll, and a short cylinder, 12, which latter projects up into the V of the shell. A supporting-die is placed within the base, the offset 1l resting thereon. A compressiondie of suitable shape is applied uniting the shell on top ofthe crimps 9, pressure applied thereto, and the parts are brought into the position shown in Fig. 6, which completes the operation.

Fig. 6 shows in vertical section a completed hod, the base 12 being united with the crimped portion of the shell 1, which forms the bottom of the hod by having its upper cylindrical portion compressed within the V- shaped peripheral edge of the portion 9. The crimps are on the upper side of the bottom with the inner ones overlying the outer ones. By this construction the pressure of the load tends to consolidate the bottom instead of, as in the old construction of integral shell and crimped bottom, separating its crimps, thus producing a much more durable, stronger, and better article than heretofore.

Having described my invention, what I claim is 1. The blank for a eoalhod, provided with slits 3 and circular creased line 4 for forming the shell 1, and the cone 2 for a coal-hod, substantially as specified.

2. The shell and crimped bottom of a coal hod of a single piece of metal, the crimps of the bottom being on its upper side, substan- V-shaped peripheral edge to form alcoli-seam, 1o tially as described. substantially as described.
