CORNER-IRON.

To all ywhom t may concern:

Be it known that I,A FREDERICK Gonnnkn, a citizen of the United States, residing at Evansville, in the county of Vanderburg and State of Indiana, have invented a new and useful Corner-Iron, of which the following is a specification. j

The present invention relates to an improvement in corner irons, and-has for an object to provide an improved structure of corner iron, which is particularly. adaptable to baskets, boxes, trunks, and the like, for not only reinforcing the corners thereof, but to also providelrunners, or downwardly LeX- tending parts, ,to support `theobjefct and admity of its being shifted around iby sliding yover the floor or'ground.

Another object of the presentinvention is to provide a structure of corner iron, in `which a relatively small amount of material is used, which is ofincreased strengthover prior structures, and which admits ofthe lwhich may be formed of relatively heavy,` hard material Vfor supporting the corner iron and theobject `to which the iron is secured. This feature of the. invention also contemplates the pecul- -iar construction or ,arrangement of parts of the cornerl iron andthe runner, whereby the runner serves as a. means for securing and rigidly holding the partsvof the corner yiron in position. v, Y Y

It is a further object'of this invention to provide a corner iron, which possesses therequired strength and durability for reinforcing the corners ofthe object to which itis applied, andwhich may be of relatively thin` sheet metal, and to provide this thin sheet metal structure with a relatively heavy or thick disk, which is oifset downwardly or depressed to provide a spherical bearing stud or support; to thus provide a relatively thin body with a relatively heavy'runner.

A still further object ofthis invention is to provide a structure of runner embracing all-of the above novel features, and which at the same time presents a neat and attractive appearance, and which eliminates projecting edges or corners, whichgnot vonly catch upon surrounding objects comingin contact with the corner` iron, but which also destroy the symmetrical appearance ofthe device.

Y The above and other objects and advantages of this invention will be more fully brought out in thel following -specific de- . walls 10 and 11, the latter lying at Y Specification of Letters Patent. Patented NOV, 6, 1917, Application filed February 19,1916. lSerial No. 79,388. Y i l ment of this invention, the same being illustrated in the accompanying drawing, wherein Y i f Figure 1 is a plan view of the blank from which themajor portion or bodj7 of the device is made. Fig. 2 is a perspective view ofthe complete corner iron, looking into the interior of the same. Y j j v Fig. 3 is a. bottom plan view of the corner iron, showing the runner in position.

Fig. 4 is a transverse sectional viewen larged, taken on .the line L1+4 of Fig. 2, and

showing one means of attaching the runner tion, as shown to advantage in Figs. 2 and 3,to provide these diverging'wings or side substantiallyy right angles to each other to 4fit against the corner of a rectangulary object, such as a boX, a basket, a trunk, or the like. The bent or angle portion of the corner iron is reinforced by the provision of an outwardly pressed offset portion 12, which, as shown in the blank in Fig. 1, is of circular form, so as to project partially into the op! posite wings 10'an`d 11 when the blankis bent transversely. The outer ends of the wings 10V and11 are provided with a number of openings 13, through which nails, screws, or the like, are adapted tok be passed to secure the corner iron in position.; The bottom of the object to which the corner iron is secured isl protected, and the wings 10 and 11 are held from spreading or collapsing, by a pair of extensions 14 and 15, which constiv tute the bottom wall of the corner iron. The extensions 14 and 15 are carried lrespectively upon the lower edges of the wings 10 and 11. Each extension is of triangular shape, and emerges 'scription of the present preferred embodi- 'zio its adjacent wingalong one side, so as to present outwardly converging edges 16 and 17 upon each projection. The inner corners of the projections 14 and 15 meet at the intermediate bent portion of the body, as shown to advantage in Fig. 1, the inner edges 1G of the extensions Haring or diverging outwardly from the same. A

As shown to advantage in Figs. 2 and 3, these extensions 14 and 15 are bent inwardly at right angles to their adjacent wings 10 and 11, and when so bent lie rin the same horizontal plane. lVhen the wings 10 and 11 are bent into rectangular relation with each other, the inner diverging edges 16 of the extensions are brought together, and abut in the central plane of the corner iron. As the extensions 14 and 15 are of the same size, and as their edges 1G and 17 extend substantially at 45 degrees outwardly from the adjacent wings 10 and 1l, the extensions, when so bent, provide a closed continuous bottom to the corner iron, and their outer 17 provide a continuous transx'ferse edge at the inner end of the device. It will be noted from the drawing that the wings l() and 11 are of a length slightly greater than the length of the horizontal bottom. This provides for a more substantial purchase of the corner iron upon the object to which it is applied.

`To take up wear and protect the bottom of the corner iron, and to admit of the easy shifting of the' object to which the corner iron is applied, by sliding the saine over the floor, the improved corner iron is provided with a runner. This runner is shown detached in Fig; 6. It comprises a disk 18 having a central spherical depressed portion 19 which projects downwardly and presents a bearing stud having an outer spherical surface adapted to engage with the fioor or ground and to slide easily thereover. By reason of the peculiar formation of the stud, being spherically depressed, the same is reinforced in all directions against crushing, so that the stud 19 is capable of withstanding considerable pressure or weight, and by its outer rounded surface admits of the easy sliding or drawing of the objects over the ground or floor. This disk 18 is secured against the lower face of the bottom of the corner iron for the purpose not only of supporting the object and preventing undue wear upon the metal forming the corner iron, but also for the purpose of securing the extensions 14 and 15 in abutting relation. The disk 18 is, therefore, secured fiat against the lower faces of the extensions 14 and 15, and laps half way beneath each of the extensions so as to position the meeting edges 16 of the extensions immediately over the vertical plane of the central portion of the runner. The disk 18 may be electric welded,

or otherwise suitably secured to the extensions 14 and 15, one manner of securing the disk in position being shown in the present drawing, wherein rivets 20 are employed. lVlien rivets are employed, it is preferred to position a pair of them at the outer edge of the disk 18, one in each of the extensions 14 and 15, as shown to advantage in F ig. 2. Another pair of the rivets 20 is positioned at the inner edge of the disk 18, one in each of the extensions 14 and 15. Fig. 4 shows the position of the rear pair of rivets 20. The rivets are headed at their upper ends upon the upper faces of the extensions 14 and 15, while the lower heads of the rivets bear against the under side or face of the disk 18. 1n Fig.` 5' of the drawings the spherical contour of the stud or depression 19 is shown and wherein the disk 18 or runner supports the object upon substantially a single point, so that the frictional bearing surface between the Hoor and the object is reduced as much as is practically possible.

From the above description it willbe noted that the corner iron of this invention provides al single blank which is stamped or cut with but a pair of relatively small extensions. The extensions are bent, and the blank is bent so as to abut the edges of these extensions to form the bottom for the corner iron. The corner iron may be made from'metal of suiiicient thickness and durability to properly reinforce the corner of the object to which the iron is applied.y It is unnecessary to make the entire corner iron heavier than is required to reinforce the corner of the object, as the invention provides a reinforcing and supporting disk or runner which is made separately and independently, and is preferably made of 105 much heavier and more durable material. This runner thus supports the robject and takes up all frictional wear to which corner irons are usually subjected. It will also be noted that should the disk or runner wear through, a new disk or runner may be easily applied to the corner iron, without the necessity of discarding the entire device. The bottom of the device is made up of but the relatively small extensions, so that coin- 115 paratively little material is required for the formation of the body of the device.

that is claimed is 4A corner iron comprising opposite walls or wlngs arranged at an angle to each other, 120 and triangular shaped flat extensions projecting inwardly at right angles from one of the edges of the said walls or wings, one extension being carried by each wall or wing, and the extensions abutting at their meet- 125 lng edges midway between the walls or wings and on a line with the inner meeting point of the said walls or wings, and a plate aving a fiat peripheral portion and an inner depressed portion which forms a stud, 130

"said plate being arranged against the underside of said flat extensions and spanning the meeting edges of the latter and secured thereto on opposite sides of said meeting edges, whereby the extensions are held from separating and a device to take up Wear is provided.

as my own, I have hereto aixed my signa-- ture in the presence of tWo Witnesses.
