JAMES R WALL, OF PITTSBURGH, PENNSYLVANIA.

OIL-CAN.

Application filed April 8, 1519.

To all 10 ham it may concern:

Be it known that 1, JAMES P. -WALL, a citizen of the United States, residing at Pittsburgh, Allegheny county, Pennsylvania, have invented a new and usetul improvement in Oil-Cans, of which the following is a full, clear, and exact descript on, reference being had to the accompany ng drawing, forming part of this specification, in which:

Figure 1 is a side elevation partially in section of one form ofoil can made in accordance with my improved method.

Fig. 2 is a sectional view through the body of the can and the collar before the collar is inserted in place, and

Fig. 3 is a similar view showing the parts assembled and brazed together.

This invenion relates to an improvement in oil cans and the method of making the same.

The object of my intention is to provide an oil can having a reinforced collar, which is made in such a manner that I am enabled to provide a higher collar and also a collar in which the upper edges thereof are rounded which will make a better finished article, form a better seal with the spout and at the same time provide means whereby the threads on the spout will more readily enthe threads on the neck or collar.

Another object of my invention is to provide an oil can of this character which can be more cheaply made by my improved method and at the same time provide a superior structure.

The precise nature of my invention will be best understood by reference to the accompanying drawing which will now be described, it being premised, however, that various changes may be made in the details of construction and the method of manufac curing the article, without departing from the spirit and scope of my invention as defined in the appended claims.

In the accompanying drawing, the reference character 2 designates the body of the can, 3 the bottom and 4 the neck, to which is threaded the usual spout 5. The lower portion or the body 2 is provided with an inwardly extending upturned flange 6 to which the outwardly and downwardly eX- tending flange 7 is brazed. The neck is formed of an upwardly extending flange 8 formed integrally with the body and a collar 9. This collar 9 is provided with down- Specification of Letters Yatent.

wardly extending inner and outer flanges l0 and 11, the flange 11 being somewhat shorter than the flange 10. The two flanges l0 and 11 are connected to each other by a rounded loop member so that the upper edge is approximately curved from the upper end or the outer wall to the upper end of the inner wall. This rounded portion forms the seat for the usual gasket on the threaded spout.

In manufacturing the oil can, the body is stamped or shaped in the form shown in Fig. 2, as well as the collar shown in said figure. The collar 9 is then forced around the neck of the body so that the lower edge of the flange 11 engages the top or the body, the neck flange on the body being located between the flanges l0 and ll. The collar is then brazed in position by flowing brazing material between the inner edge of the flange 10 and the body portion, as indicated at 12 in Fig. 3. After the collar has been brazed into position the inner portion of the collar is threaded, as indicated at 13. Ihe bottom is then placed in the lower end of the body and the flange 6 spun or stamped, over into position; and afterward the flange 6 is brazed to the bottom by flowing the brazing material 14 into the joint, as indicated in Fig. 1.

As the collar 9 is formed, as shown in Fig. 2, the bore thereof is of the proper size for the reception of the tapping tool without the preliminary step of reaming, and as the opening from the upper end is flared the tapping tool will readily enter and after it is tapped the threads on the lower end of the spout will readily engage the threads in the neck. I

I claim:

1. An oil can having an upwardly extending neck formed with an unthreaded inner surface, and a reinforcing member inserted within said neck and having at its upper end a downwardly bent flange fitting the neck exteriorly thereof, said member being internally threaded, and a threaded spout engaging the threads of said member, that portion of the reinforcing member within said neck extending below the point where the neck joins the body of the can and providing a groove or recess between it and the body of the can, and brazing material in said groove or recess and positively uniting the reinforcing member to the can, substantially as described.

2. An oil can having' a body portion of sheet metal and formed with an upwardly projecting neck, a reinforcing member also of sheet metal seated within the neck opening and having at its upper end a clownwardly extending flange fitting the exterior surface of the neck and abutted at its lower end against the body of the can adjacent to the base of the neck, said member having an internal thread and being extended within the body of the can sufficiently below the neck to form a surrounding space or groove for the reception of brazing material, and brazing material seated in said space or groove, substantially as described.

3. An oil can having an upwardly extending neck formed with an unthreaded inner surface, and a reinforcing member inserted Within said neck and having at its upper end a downwardly bent flange-fitting the neck exteriorly thereof, said member being internally threaded, a threaded spout engaging the threads of said member, that portion of the member within said neck extending below the point where the neclrjoins the body of the can and providing a groove or recess between it and'the body oi the can, and brazing material in said groove or recess and positively uniting the reinforcing member to the can, the flange fitting the exterior portion of the neclr being united to the reinforcing member by means of a rounded bend, substantially as described.

In testimony whereof I have hereunto set may hand.
