Application filed June a, 190k. Serial No. 436,481.
To all whom it may concern:
Be it known that LGEORGE N. BAKmga citizen of the United States, residing at.
Decatur, in the county of Macon, State of Illinois, have invented certain new. and useful Improvements in Metal Frames, of which the followingis a specification, reference be-.
ing had to the accompanying drawings.
This invention relates to improvements in frames and particularly to frames designed for use in holding sections or pieces of wiregauze, whereby awindow screen is thereby formed. v
I have illustrated my improved frame as a part of a window screen but it is tobe understood that I do not restrict my invention to such use. The object of'my inventionis to provide a framethat can be readily formed from a single strip of sheet metal and by reason of its novel construction will be exceedingly strong and rigid. I attain this object by the construction shown in the drawings and hereinafter specifically described.
That which I believe -to be new will be pointed out in the claims.
In the accompanying drawings :Figure 1 is a side elevation of .my improved frame, and showing secured therein a section or piece of wire-gauze (partlybroken away), the frame and gauzetogether thus forming a window screen. The screenshownis of that kind wherein two parts are employed together and are adjustable upon each "other so as to fit "windows'lof different widths. Fig. 2 is a vertical section taken at line 22 of Fig. 1. Fig. 3" is a cross-section taken at line 33 of Fig. 1. Fig. 4: is a'detaiL-being a perspective view of a portion of the strip from which the frame is formed, showing the form assumed by the Jstripin the first part of the operation offorming a corner. Fig. 5 is a view similar to Fig. 3 and showingthe form assumed by the strip upon the next operation in which the corner is completed. Fig. 6 is a view similar to Fig. 5, except that one of the barsof the frame has been given an additional longitudinal bend in order to produce a channel such'as in the upper and lower bars of the complete frame that is shown in Fig. 1. Fig. 7 is a perspective view of a corner of the frame, the view.
being taken from the side opposite to that shown in Fig. 6; Fig. 8 is a View'similar to that shown in Fig. 7 but taken in a different i a cross-section taken at line 99 of Fig. 6.
Fig. 10 is an enlarged detail, being a cross section taken atline 1010 of Fig. 6.
' Referring to the several figures of' the drawings, in which corresponding portions 'erence characters- A, Band C indicate, re.- spectively, the upper, the end and the lower bars of the frame, said three bars being formed from a single strip of sheet metal.
1 The terms upper, end and lower as herein used are merely for convenience of description, as it will of course be understoodthat what in one case would be prop erly described as an upper bar would in another case'be differently termed. In forming the frame, I take a strip of sheet-metal'of suitable width and give toit at or near its longitudinal center a bend so that, as clearly shown in Fig. 4:, there will be left a narrow space between the two thicknesses of 'material between which, at the proper time, the edges of the sheet of wire-gauze, if a window-screen is to be formed, can be inserted.
. of the device are indicated by the same ref- V Referring now particularly to Fig. 4,to
form a corner of the frame, the doubled strip is given two edgewisebends as at a--a, such bending causing an outward bulging of the metal at two places in each thickness of the folded strip and producin at each side of the folded strip a pair of substantially triangular-shaped parts each of a double thickness of metal. The pair of triangular-shaped parts atone side of the folded strip are indicated by b and the pair on the opposite "side by 0. The cdgewisebends imparted to the folded strip at a-a.are of a degree to cause the folded strip to assume the shape of' a device'having twoarins or branches -(Ze standing at right angles to each other, and which afterward become two of the sides of a right angled frame. These two arms or branches are separated by a doubled portion f, the upper edge of which to the outer or folded edge of each 0 the arms or branches referred to. As shown in Fig. 4, the pair of doubled triangular parts b are bent or turned toward each other while the corresponding parts on the oppos v Fig. 5, so that one of the said'pairs will position, Fig. 9 is an enlar'ged'detail, being liefagainst the portion fof. the strip while 'must be at practically an angle of 4:5 degrees the other pair will lie against the arms or.
branches cZ--e.
While the arms or branchesde are, by reason of the edgewise bending imparted to the folded strip at the points a-a, now at right angles to each other, it is evident that such arms or branches would not form satisfactory sides of a frame that was designed to completely fit within a rectangular opening,-as, for example, where the frame was intended for use as a windowscreen frame,-for it is evident that at the corner of the window-opening there would be left a space between the inclined edge of the doubled portion and the corner of the window-opening. The next step, however, in the operation of making the frame produces the desired sharp corner. Such step consists in bending each of the branches cZ.e longitudinally so as to produce on each of them a flange g. I11 thus bending the arms or branches to produce these flange portions, the triangular parts Z)b and cc are each necessarily bent also as well as the intermediate portion f. The lines upon which this bending to form the flanges gg meet, or nearly so,is best shown in Figs. 5 and 6, and hence a sharp corner is formed adapted to correspond very closely to the sharp corner of an opening,as a windowopening. By this construction, a corner for a right angled frame is formed without the necessity of disposing of the surplus metal, necessarily caused by edgewise bending, at the corner itself, which, in the actual construction of the frame, is a matter of some difliculty. By disposing of this surplus metal in the manner shown, whereby a portion of it appears at each side of the corner, the work of construction is rendered easier, a neater appearance is imparted, and stronger device is formed than where all the surplus material is accumulated directly atthe corner as in prior constructions. The manner of making all of the corners of a frame will be the same as that just described.
It is of course obvious that a four-sided frame can be made of a continuous strip, as described, although in Fig. 1 I have shown such continuous strip as forming but three sides of the frame, and that is for the reason that I have shown my invention embodied in a frame adapted to be used in connection with another similar frame which is to be slidingly connected with it. In the complete frame thus shown, the fourth bar of the frame is formed of a separate strip having its ends interfolded with the upper and lower bars A and C. This fourth bar is indicated by D, and it will be noted that it is located a little distance from the ends of the strip that forms the other bars A, B and C, so that there are left, as shown, two ends that extend b yond that portion of the frame that incloses the wire-gauze, such protruding tends receiving and supporting other prot-ruding ends on another correspondinglyshaped screen-frame.
In the construction shown, the flange portion 9 on the parts that constitute the upper and lower bars A and C is a little wider than the flange formed on the end bar I) and is so made to permit these wider flanges to be turned or bent longitudinally to provide each with a supplemental flange 71, as clearly shown in Fig. (3, thereby making each of the bars 3rC of channel form, the better to adapt them to receive the upper and lower bars of another screen-section,
3y the construction shown and described, I produce a very strong and rigid frame from a single strip of sheet-metal. By giving two edgewise bends as at (Z(l so as to bulge out the metal in the form of the two substantially triangular parts b b, I produce two bars or sides of the frame that are disposed at right angles to each other and at the same time have the metal so disposed as to render it easy to longitiulinally bend these arms or branches to form flanges for stiffening purposes, which bending, as has been shown, also produces a sharp and perfect corner, and at the same time such parts b-b form in connection with the intermediate portion f a very strong corner brace.
hat I claim as my invention and desire to secure by Letters Patent is l. A metal frame formed of a single strip, a corner of the frame being formed by two edgewise bends in the strip, a substantiallytriangnlarly-shaped fold being formed at each of said bends, the frame bars that extend from said corner being each provided with a longitudinal flange, each flange tending through one of said folds.
2. A metal frame formed of a single strip, a corner of the frame being formed by two edgewise bends in the strip, a substantiallytriangnlar shaped fold being formed at each of said bends, the frame bars that extend from said corner being each provided with a longitudinal flange, the two flanges extending respectively through said folds and meeting between said bends.
3. A metal frame consisting of a strip bent longitudinally upon itself, a corner of the frame being formed by two edgewise bends in the strip, a, substantially -triangularshaped fold being formed at each of said bends, the frame bars that extend from said corner being each provided with a longitudinal flange, the two flanges meeting between said bends.
i. A metal frame formed of a single strip, a corner of the frame being formed by two edgewise bends in the strip, a substantiallytriangular-shaped fold being formed at each of said bends, the frame bars that extend from said corner being each provided with a longitudinal flange, the two flanges meeting between said bends, and one of said flanges being provided with a supplemental flange to form a channel in one ofsaid bars.
5. A. metal frame formed of a single strip folded longitudinally on itself, and having two edgewise bends, whereby the corner betweentwo bars of the frame is formed, and two oppositely-located substantially-triangular-shaped folds at eachof said bends, said bars being each provided with a flange that extends through two of the said oppositelylocated triangular-shaped folds.
6. A metal frame formed of a single strip folded. longitudinally on itself, and having two edgewise bends, whereby the corner between two bars of the frame is formed, and two oppositely-located substantially-triangular-shaped folds at each of said bends, said bars each being provided with a flange that extends through two of the said oppositelylocated triangular-shaped folds, said triangular-shaped folds on one face of the frame being bent toward each other and those on this1 opposite face being bent away from each ot er.
