Referring now more particularly to the draw-.-

ings, a frameconstituting the present invention is made from metal angle bar stock comprising the customary respectively perpendicular legs I and 2. As shown in the draw the leg I of the angle bar is of less width than the leg 2 thereof but thisparticular relationship is not essential and may be otherwise.

g In making a frame in accordance with this in vention a predetermined length of metal angle bar A, equal to the developed length of the proposed frame structure, is cut from the barstock. and a predetermined number of apertures or openings 3 are punched or otherwise formed in the saidqangle bar at predetermined spaced intervals therealong, each particular aperture 3 being located along the angle bar A so that the transverse axis of said aperture will reside in the same plane as the ads about which the bar A will be bent to form a. corner of the frame. The apertures 3 may be formed in the bar by an independent operation but for production work it is desirable to form the apertures in the bar at the same time that the desired predetermined length of the angle bar A is cut from the stock.

It will be noticed by a reference to Fig. 2 of thedrawings that the apertures 3 formed at spaced intervals in the angle bar, are in each instance so positioned that metal is removed from both of the legs I and 2 of said bar, and that the greater portion thereof is removed from the first mentioned or shorter leg 1 than from the leg 2. The purpose for this particular arrangement of the apertures 3 in the angle bar with respect to the legs i and 2 thereof will be described more in detail hereinafter.

When the angle bar A has been cut to the desired length from the stock and the apertures or openings 3 have been formed therein as previously set forth, the said angle bar is placed in a bending device designated generally as 4.

Referring to Figs. 3, 4 and 5 of the drawings the bending device 4 comprises sections B and C pivotally connected at 5, each of said sections 13 and C including a bracket portion 6 and a projecting web I having a lip 8 for respectively embracing the legs 2 and I of the bar A. The sections of the clamp or bending device 4 are firmly secured to the leg 2 of the angle bar by means of bolts 9 threaded in the bracket portions 6 which embrace leg 2. As shown in the drawings one of the clamp sections C is provided with a handle III for actuating the same relatively with respect to the other section B about their common pivot 5. It should be noticed that the portions 6 of each section of the clamp grip the leg 2 of the bar A and support the same closely adjacent each end of the opening 3 in the bar, the purpose for which will be described hereinafter. With the clamp or bending device 4 firmly in position on the angle bar A, one or both of the sections B and C thereof may be pivoted toward each other until the adjacent portions of the leg 2 of the bar are respectively at an angle of 90, or any other particular angle that may be desired, thus forming a corner of the frame. The clamp or bending device 4 may then be removed from the bar by loosening the retaining bolts or screws 9. a

With regard to the bending of the angle bar A to form a corner in a frame, it is pointed out that the principal object of the invention is to provide such a corner wherein the radius of the projecting horizontal leg I at said corner will be substantially equal to the width of the said leg at all other points throughout the frame; in other words, will be of substantially uniform constant width throughout the frame irrespective of any bending of the angle bar to form a corner therein. Obviously in order that the horizontal projecting base leg I may be of substantially uniform width throughout the entire frame, the periphery of said leg at the corner must have a curvature the peripheral radius of which isno greater than the width of the'leg I, and in order to form such a. curve with the leg] it is necessary that themetallic particles composing the same be stretched or elongated through circular arcs having a common center, the outermost or peripheral are having a radius substantially equal to the width of the leg.

In the present instance the stretching or elongation of the metallic particles in the horizontal leg I at a corner is made possible by the formation' of the apertures 3 in thebar A, and it will be noticed that said apertures function to sever the leg I from the leg 2 between the ends of each opening 3 formed therein. Consequently with the portions 6 of the bending device 4 gripping the leg 2 adjacent each end of such an opening 3, actuation of the sections B and C of the device toward each other about their common pivot 5 will cause the metal in the horizontal leg I to, be stretched or elongated in the manner previously described, and when so stretched or elongated the periphery of the legI at the corner will form a curve the radius of which is substantially equal to the width of the said leg throughout the remainder ofthe angle bar A.

Furthermore it will be obvious that if the metal fibres in leg I are stretched or elongated at a corner in the above manner, the metal fibres in the leg 2 must be compressed proportionately or a substantially equivalent amount of the metal must be displaced therefrom. Thus it will be seen that by severing the leg 2 from the leg I for the length of an opening 3, that portion of the leg 2 between the ends of said aperture being freed from connection with the horizontal leg I, will be displaced outwardly with respect to the adjacent portions of the leg 2' and assume the form of a loop as shown in Fig. 4 of the drawings.

A particular feature of the invention resides in the fact that all of the operations herein described for making a frame in accordance with the present invention may be done cold without any heating of the metal whatever, and when all of the corners in a particular base frame structure have been formed in the manner described above, as for instance the rectangular base frame structure disclosed in Fig. 4, the adjacent ends of the angle bar may be welded or otherwise permanently secured together as indicated at III.

It is desirable to point out at this time that in ordinary practice the corner angles of a frame made in accordance with this invention should be formed in machine opera-ted mechanisms as contrasted to the manually operated clamp or bending device 4 which has been described herein solely for the purpose of showing in as simple a manner as possible just how the respectively perpendicular leg portions of the angle bar A are gripped or engaged by portions of any mechanism used so that the angle bar may be formed into a frame in accordance with the invention.

A frame structure made in accordance with this invention is of an extremely rigid nature and sufficiently durable to withstand many years of use. Such a frame is particularly adaptable for use as a base frame structure for modern ranges and other cabinet like structures of the more so-called modemistic design, wherein the wall panels extend continuously from the top to the bottom of such a structure, and may or may not be provided with supporting legs or casters.

For instance by providing such a base frame with a horizontal projecting base flange or leg I, as shown in Fig. 8, a wall panel II stamped from metal sheet and provided with a peripheral flange I2 of a width substantially equal to the width of the upper surface of the said leg I may conveniently be mounted upon said base flange or leg I and secured thereto at its peripheral flange in any suitable manner. A reference to Fig. 8 will disclose that the particular arrangement Just described will give a neat, clean-cut, external appearance to such a structure which is of pleasing appearance and in conformity with present day trends in the construction of household furnituresuch as cabinets, cabinet ranges and the like.

A solid wall panel of wood or other fibrous texture or composition (not shown) might readily be substituted for the stamped metal wall panel II, with exactly the same result as far as the neatness and appearance of the structure are concerned, and in some structures, it may be desirable to provide the frame with a horizontal projecting flange I of somewhat greater width than the width of a wall panel II supported thereon, so that the former may project a small distance beyond the plane of the surface of said wall panel as indicated at I3 in Fig. 8, thus forming in effect a bead or strip at an edge of the wall panel which will act as a fender or guard against objects being knocked against the surto the adjacent 4 leg I is sufficient having a substantially vertical leg and an integral face of the wall panel, marking or chippin the same. The projecting edge It may also be painted orplated with a color in contrast to the color of the wall panel and thereby increase the external beauty and eflect oi'the same.

The adaptation of the present invention .to structures of the general class of cabinets is further illustrated in Figs. 9 and 10 of the drawings, and in keeping abreast with the modem trend of cabinet design wherein the majority or the cornersoi such structures are rounded off by molding or other cabinet workers methods, the curved corners of the frame as will be noticed, lend themselves admirably to this particular feature. It is important to note that the bottom edge of the loop of metal displaced with respect portions of the leg Z'is relatively spaced with respect to the upper surface of the projecting leg I by reason of the formation of the openings 3 in the angle bar so that a portion of metal is removed from both of the legs I and 2 respectively as previously described in detail. And this space intermediate the'displaced metal and the upper surface of the horizontal so that the. peripheral flange ii at the bottom of the stamped metal wall panel it may easily iit therebetween and beneath the displaced loop of metal to provide a further support and increase the strength of the wall structure. 7 v

While the particular construction of the base frame has been specifically set forth for the purpose of description together with examplesof its adaptation to several specific arrangements of wall panel sectionstherewith, it is n t intended that the invention be limited precisely thereto but that the same may have innumerable uses and adaptations so long as the same are within the scope of the annexed claims.

What I claim is: 1. A skeleton frame structure composed of bent angle bar stock and including alternately disposed corner and adjacent side portions each horizontal leg projecting outwardly from one edge of said vertical leg, said vertical leg being severed irom .the horizontal leg at said corner portions and displaced to compensate for elongation in said horizontal leg at the corner portions.

2. A skeleton frame composed of bent angle bar stock and including corner and adjacent side portions each having a vertical leg and an integral outwardly projecting-horizontal base leg the peripheral edge of which at said comer portions forms a circular archaving a'radius substantially equal to the width of said leg in a side portion, said vertical leg being severed from the horizontal leg at the comer-portions of the frame and displaced to compensate for the elongation in said horizontal leg in arranging the same so that its peripheral edge forms a circular arc the radius of which is substantially equal to the width oi. said leg at a side portion.
