TUBULAR CONSTRUCTION KATERIAL.

Application fled October 88, 1922. Serial Io. 598,884.

My present invention relates to tubular construction materials, especially for the metal frames of doors, windows and the like. Such tubular metal parts are often complicated, are comparatively difiicult to manufacture, and are rather expensive as ordinarily made. In some cases such tubular members cannot be conveniently fabricated at all, due to the particular complicated shapes which such members may be required to possess.

It is an object of the invention to provide a metal tubular member for the frames of doors, windows and the like, which can be manufactured conveniently and cheaply, however complicated its form may be.

It is another object of the invention to provide a metal tubular member for the frames of doors, windows and the like,

2 which shall be made from extruded bronze,

or equivalent metal, in such a manner that the necessary parts constituting the tubular member may be fabricated in a simple, accurate and expeditious manner, resulting in a superior product having any desired cross section, however complicated, for use in a wide variety of cases for which the much more expensive substitutes now offered for sale would not ordinarily be available.

In the accompanying specification I shall describe, and in the annexed drawing show, several illustrative embodiments of the pres-- ent-invention. It is, however, to be understood that my invention is not limited to the illustrative embodiments thereof herein shown and described for purposes of illustration only.

Referring to the drawings, wherein I have illustrated the aforesaid illustrative embodiments of the present invention:

Figure 14 is a similar view of still another embodiment of the present invention in the form of a top rail.

Before describing the method and product of the present invention in detail, it may be desirable briefly to point out the shortcomings and the disadvantages of the present state of the art to which the present inven tion belongs. In making hollow tubular members for metal door and window constructions, according to the practice that has hitherto revailed, it has been customary to form suc tubular members of several sections by welding, brazing, or some similarly diflicult and expensive metal-joining process. The resulting product is not only expensive, but also comparatively impractical, especially considering the great necessity of providing construction materials of the character set forth above, which shall have long life and wear, and which shall possess the necemary weatherproof properties. Certain forms in, which these products were desired,

to be made could not be made at all by ex trading bronze or equivalent metal in the usual way, nor by pressing the same out of steel.

By means of the present invention, the disadvantages pointed out above are sub stantially avoided, and numerous advantages of great commercial and mechanical value obtained.

Outlining, first, the method of the present invention, more or less briefly, the same comprises forming tubular construction materials of the general character specified above, in two, three, or more, cooperating sections. This may be lone by extruding bronze or equivalent metal in the desired shapes. The cooperating sections are so arranged that certain of such sections are provided with one or more flanged or otherwise suitably shaped portions to cooperate with corresponding grooves in the other section or sections. The cooperating sections may be locked together by iuscrting the flanges of the one 5081 31011,

or sections into the corresponding grooves of the other section or sections. In this way, particularly as a result of the irregularities which inevitably are to be found in the flanged portions of the tubular section members and in the grooves of the cooperating tubular section members, the various sections will be securely locked together in tubular form by their frictional contact, without the use of welding, brazing or other expensive metal-joining process.

Turning now 'to the various illustrative embodiments of the present invention, and referring more particularly to the embodiment shown in Figure 1 of the drawing, the transom bar comprising said illustrative embodiment has the form of a hollow tubular member gencrallv designated by reference character 10 and consisting of two tubular section members. designated by reference character 11 and 12*- respectively.

The tubular section member 11. which, like the tubular section member 12*, may readily be made by extruding bronze or equivalent metal, is provided with the

upstanding flanges

13 and 14 of which the flange 14 is slightly wider than the flange 13 and is provided with the flange member 15. Inthis way there is provided a recess 16F which it is desirable that the transom bar shall possess. The tubular section member 11 is provided with the downwardly turned flanges 17 and 18 which cooperate with the respective angular flanges 19 and 20 respectively, for providing grooves 21 and 22, for a purpose subsequently to be described in greater detail.

The remaining tubular section member 12*, there being in the embodiment now being described but twosnch section members, is provided with a plurality of inwardly turned flanges 23 and 24 for cooperation with the

flanged portions

17, 18, 19 and 20 definin the respective grooves 21 and 22* of the tubular section member 11.

It may here be noted that in determining the shape to be given to the various tubular section members which are to be assembled to form the hollow tubular construction member, such a shape is chosen for each member as will enable the member to be readily made by extrudingbronze or equivalent metal, and so that there will be as few tubular section members and as few joints as possible. The number of sections will depend, of course, upon the particular cross- .section of the tubular member to be constructed. The form which each section member shall have depends also upon the neces sary forms or shapes of the flanges and corresponding grooves, which should be distributed in such a way as to enable the tubular member to be readily fabricated and assembled so as to possess the maximum weatherproof and wearing qualities.

Two tubular section members 11" and 12 are joined by sliding the flanges 23 and 24" into the respective grooves 21 and 22 of the section 11. Due to the minute natural irregularities of the flanged portions 23 and 24 and of the corresponding grooves 21 and 22, the two sections will closely and tightly fit together to form a rigid weatherproof tubular member, in this case, a transom bar, without the use of welding, brazing or other expensive metal-joining operation.

In Figure 2 I have shown a transom top rail, generally designated by reference character 10 and consisting of a section member 11*. provided with the upstanding flange 12 and the flanged

portions

13 and 14* cooperating with the corresponding

angular flanges

15 and 16*, respectively, to form and define the respective grooves 17* and 18". Cooperating with the section member 11 is the section member 19 which is provided with the angular flanged portions 20 and 21 for fitting into the corresponding grooves 17 and 18, respectively. The manner of assembling this tubular construction device, comprising a transom sash top rail, will be clear from the detailed description of the transom bar 10 appearing in the earlier portions of this specification. It may here be noted that the section member 11 is provided with the integral weatherstrip 22* which is preferably of T-shaped cross-section.

Referring to Figure 3 of the drawing wherein I have illustrated a sash stile, generally designated by reference character 10, the same comprises a section member 11 provided with the upstanding flange 13 and the

flange portions

14 and 15 cooperating with the angular flange portions 16 and 17. respectively, to define the respective grooves 18 and 19. It will be noted that be noted that the section member 11 is eeann the flange member 15 has an extension in the form of an integral weather-strip 20. The section member 12 is provided with the angular flanged portions 21 and 22 for cooperation with the grooves 18 and 19 of the other section member 11. The manner of assembling this form of the invention is the same as for the form shown in Figure 1 of the drawing, as set forth in detail above.

flanged portions

14 and 15 which cooperate with the respective flanges 16 and 17 to define the respective grooves 18 and 19. It will tovided with an extension in the form 0 an inte ral weather strip 20".

The section member 12 is provided with the angular flanges 21 and 22 cooperating with the respective grooves 18 and 19". The section member 12" is also provided with the integral weather strip 23" which is preferably of T-shaped cross-section. The manner of assembling this device is the same as for the device shown in Figure 1 of the drawing and described in detail above.

It will be noted that in the form of invention shown in Figure 4 of the drawing, each section member has two sides, as is also the case with the members shown

iniFigures

5, 6, 7, 10, 11, and 13; whereas, in the tubular members of the remaining figures of the drawing, such members are made up of sections of which one forms but one side of the tubular device and the other member forms the remaining three sides of the device. It will also be noted that the tubular members thus far described have been made up of two sections, which is true of all of the tubular devices shown in the drawings; although it is, of course, to be understood, that the tubular device may be made up of three or more sections, if desired or necessary.

Summarizing the features of the above described embodiments of the resent invention, it is to be noted that am the first ,to make a tubular metal construction material without the use of brazin Welding or similarly expensive and unsatis actory metaljoining operation. While I prefer to use the method of extrusion for forming the various tubular sections, various other metal-working processes may be used for this purpo:e, although I prefer to extrude the various sections of bronze or equivalent metal.

The' 'choice of the form for the various tubular sections cooperating to form the tubular members, depends upon the feasibility of extruding the metal where this process is used, as is preferred. It is also preferred that the joints of the various sections shall be so arranged as to avoid exposing such joints to the weather. It is also preferred that the joints shall be so located as to be as little visible as possible, thus giving the device a more neatand finished appearance.

The advantages of the foregoing constructions are that their fabrication saves much time, labor and material, and results in a more rigid structure without the use of welding, brazing or similar expensive metaljoining processes. Furthermore, the various sections are locked together and cannot separate even when subjected to unusual stralns and stresses, as during fires. Constructions using these materials are more compact and more weatherproof than the competing niaterials hithertoused in their stead.

\Vhat I claim is:

1. A tubular member for metal window frames and the like, comprising a plurality of sectional elements at least one of which has a main web portion and at least one pair of cooperating flange portions disposed adjacent an edge of said main web portion and transversely thereto, one of said flange portions having an ed e portion thereof turned inwardly towards the cooperating flange portion to thus provide a channel, the other of said sectional elements having one or more flange portions each extending transversely to the main web portion of said last-mentioned sectional element and fitting into said channel.

2. A member for metal window frames and the like, comprising a sectional element having a main body portion provided with a pair of cooperating flange portions adjacent at least two of the laterally disposed portions of said main body portion and disposed transversely thereto, one of the flange portions of each pair of cooperating flange portions having an edge portion thereof turned inwardly toward the cooperating flange portion of the pair, the edge portions of at least two such pairs of cooperating flange portions being turned away from each other.

3. A member for metal window frames and the like, comprising a sectional element having a main body portion provided with a pair of cooperating flange portions adjacent at least two of the laterally disposed portions of said main body portion to thus provide a plurality of channels, one of the flange portions of each pair of cooperating flange portions having an edge portion thereof turned inwardly toward the cooperating flange portion of the pair, the edge portions of at least two such pairs of cooperating flange portions being turned away from each other, in combination with acooperating sectional element having a main body por tion and a plurality of flange portions extending transversely to such mam body portion of said last-mentioned sectional element and fitting into said channels.
