PROCESS FOR USE IN THE FORMATION OF ATTACI-IING MEANS FOR BAIL-EARS.

Specification of Letters Patent.

Patented Aug. '7, 1917.

Application filed November 15, 1915. Serial No. 61,536.

To all whom it may concern:

Be it known that I, HENRY A. BEYER, residing at Corona, Long Island, in the county of Queens and State of New York, have invented certain new and useful Im provements in Processes for Use in the For- 'mation of Attaching Means for Bail-Ears and the like, of which the following is a specification.

This invention relates to an improved process for use in the formation of attaching means for bail ears and the like.

A particular object of the invention is to provide a process by the use of which the bail ear is rendered stronger and of more uniform strength than heretofore.

The more specific object is to provide a process for the formation of the attaching means for the bail ear whereby the particular portion of the material from which the attaching means is formed is drawn from the adjacent portion of the material to which the ear is to be attached in such manner as not to be subjected to any such tensile or shearing strains as would detrimentally affeet its strength.

Other objects and aims of the invention, more or less specific than those referred to above, will be in part obvious and in part pointed out in the course of the following description of the elements, combinations, arrangements of parts and applications of principles, constituting the invention; and the scope of protection contemplated will be indicated in the appended claims.

In the accompanying drawings which are to be taken as a part of this specification, and in which I have shown a merely preferred form of embodiment of the invention:

Figure 1 is a side elevational view of a portion of a receptacle, having an ear formed thereon constructed in accordance with the provisions of this invention.

Fig. 2 is a vertical sectional view taken substantially upon the plane of line II-II of Fig. 1.

Fig. 3 is a side elevational view of a portion of the receptacle showing the same as it appears in accordance with the first step of this process.

Fig. A is a vertical sectional view taken substantially upon the plane of line IVIV of Fig. 3.

Fig. 5 is a view similar to that shown in Fig. 3 but showing a further step of the process.

Fig. 6 is a vertical sectional view taken substantially upon the plane of line VI-VI of Fig. 5.

Fig. 7 is a view similar to that shown in Fig. 3 but showing a still further step in the process and:

Fig. 8 is a vertical sectional view taken substantially upon the plane of line VII- VII of Fig. 7.

Referring to the drawings for a description of the structure illustrated therein, the reference character L indicates the wall of the pail, or other article upon which the ear is formed.

The reference character G indicates the button which is fixed to the wall L and which I constitutes the essential element of the ear. The bottom wall of the button is apertured and flanged inwardly as at 2 for receiving the bail H as is the usual practice.

The means by which the button G is fixed to the wall L consists of an annular rib 3 which is formed upon the wall and which provides a pocket upon the wall within which the outwardly flaring edge of the button is received.

The button is of such size as to fit snugly within this pocket, and after the button has been placed therein the rib is bent over upon the flaring edge of the button, thereby locking the button rigidly in place.

In Figs. 3 to 8 the preferred process is illustrated by means of which the rib 3 is produced.

In accordance with this process the portion of the wall L, where it is desired to form the ear, is first pressed outwardly by suitably formed dies to form a projection 4:, as seen in Figs. 8 and 4:. The projection 4:, is preferably circular and is preferably of somewhat greater diameter than the diameter desired for the ribs.

This pressed or bulged out portion 4 has its outer portion or circumference formed by curved portions of the material. This insures that the material utilized in forming the'bulged portion will not be cut or creased so as to weaken the same. Neither is the ma terial forming the portion 4: made appreciably thinner as the dies are so formed and utilized as to draw or stretch somewhat the material surrounding the bulged portion.

As a second step, the annular marginal portion of the projection 41; is pressed back again by suitable dies into the plane of the remainder of the wall as seen in Figs. 5 and 6. This reduces the size of the projection 4: and makes it of a diameter substantially that desired for the diameter of the rib 3. The

sides .5 of the projection now are substantially at right angles to the plane of the wall, whereas at the end of the step shown in Figs. 3 and 4 they were at an incline or curved,

ducing the right angular disposition of the sides 5 of the projection avoids undue localization of stretch, such as might otherwise tend to fracture the material at some point. In bending the metal out in curved cross section, as in Figs. 3 and 4:, very little localized stretch is felt. The stretching is gradual and uniform over a relatively wide expanse. The metal thus drawn is simply bent back again to form the right angularly disposed side walls practically without any stretching whatever.

As a third step in the process, the central portion of the projection 41:, is pressed back again by suitable dies to the plane of the wall L as shown in Figs. 7 and 8. In this step a portion of the sides 5 is bent, or folded, inwardly, thereby reducing the .height of said sides, and forming rib 3.

The rib thus formed is integral throughout with the wall L. It is of double thickness, and is, therefore, of great strength. There is absolutely no danger of a leak as no opening of any kind has been formed through the wall. The inner surface of the receptacle is left smooth and even.

After the rib is, formed, the button is, positioned and the rib ispressed or bent over bysuitable dies, as above described with regard to Figs. 1 and 2. The operation of pressing over the rib causes the angles 7 and '8 to be-mashed down into quite sharp cornerswhich abut together and effectually close any space which may have previously existed between them and at the'same time this operation renders the surface practically unbroken.

It will be seen that, by means of my construction and my process for providing the same, the ear is to all practical purposes an integral part of the receptacle. The process is also carried out in such a way as not to weaken the material or the receptacle or form any aperture therein.

As many changes could be made in this construction without departing from the scope of the following claims, it is intended that all matter contained in the above description, or shown in the accompanying drawings shall be interpreted as illustrative only and not in a limiting sense.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

ing an annular rib upon a member, which consists in first pressing out a portion of the member to form a projection thereon having an annular outstanding wall portion, and then pressing inwardly a part of the outstanding wall to form an annular wall portion substantially parallel to the remainder of said first mentioned annular wall portion. as seen at 6 in Fig. 4. This method of pro- 2. The herein described process of forming an annular rib upon a wall, which consists first in pressing outwardly a portion of the wall to form a projection thereon of somewhat greater diameter than the diam- 1. The herein described process of f0rm-- eter desired for the annular rib, thenpressing inwardly an annular marginal portion of said pro ection suficient to reduce the diameter of the projectionto that desired for the rib, and thereafter pressing inwardly the central portion of the reduced projection, so as to leave outstanding only the .annular wall of the reduced projection and an annular wall parallel therewith extending from the outer edge thereof inwardly to said central portion.

.3. The herein described process of forming a bailear which consists in pressing outwardly a portion of the member to form a projection thereon having an annular out-' standing wall portion, then pressing inwardly a part of the outstanding wall port1on to form an annular wall portion substantially parallel to the remainder of the' first mentioned annular wall portion, then positioning a bail-carrying button within the space defined by the annular wall portions, and finally bending inwardly said annular portions into engagement with the bail-carrying button to lock the bail-carrying buting the rib member about a portion of the V ear member.

5. The herein described process of forming an annular rib integrally With a piece of sheet metal, which consists in bending out in one direction that portion of the metal from which the rib is to be formed and then bending back a portion only of said metal previously bent out.

6. The herein described process of forming a rib integral With a piece of sheet metal Within the marginal confines of said piece of sheet metal, Which consists in first stretching that portion of the metal from Which the rib is to be formed, bending the stretched part to form a Wall upstanding at approximately right angles to the surrounding unstretched portion of the metal, and then bending back a portion only of said Wall Copies of this patent may be obtained for five cents each, by addressing the into substantial parallelism With the remaining upstanding portion of said Wall.

7. The herein described process of forming an annular rib integrally With a piece of sheet metal Within the marginal confines of said piece of sheet metal, which consists in first stretching an annular portion of said piece of sheet metal, then bending the stretched annular portion to form a Wall upstanding from the surface of said piece of sheet metal, and then bending back the outer portions of said upstanding Wall into substantial parallelism with the inner portion of said upstanding Wall.

In testimony whereof I afliX my signature.
