METALLIC BUILDING STRUCTURE.

Specification of Letters Patent.

Application filed April 26, 1916. Serial No. 93,585.

Be it known that l, Josue-ir lll/Annan Jones, a citizen of the-United States, residing at the city of St. Louis, State of Missouri, have invented certain new and useful improvements in Metallic Building Structures, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming a partof this specification.

This invention relates 1generally to metallic building structures `and more specifically to an improved construction vtor a structural.member which may be variously employed as a column, strut member and the like. i

As is welllrnown, in various metallic structures, such as nbridges, towers, framing for buildings and the like, numerous mem- Ibers are employed as columns, struts, or bracing elements, which are so disposed as to carry longitudinal stresses, and the most important factors of which, therefore,- are a .suiiicient amount of metal and such a disposal of same as to have a sufficient radius of gyration to -lend the necessary stability. In present practice, such members are fre'- quently formed as laced or latticed members, common forms ot' which consist of tivo or Iore commercial shapes joined by lacing or latticing of narrow strips riveted to the members and serving to keep them properly spaced apart to give the necessary stillness or stability.

The principal object of my present vinvention is to provide an improved construction for a structural member of this sort, by virtue 'of which construction the cost of the vmember is -materially decreased, and a memin any of the fashions now commonly employed.

A still further object of my invention is the provision of a structural member which is particularly adapted for use in reinforced concrete construction, because of the facili- Patentea Juiy 2e, 1919i ties which it affords for the disposal, accom-.-

modation, and attachment thereto of concrete reinforcing rods.

Other and further objects of my invention will be obvious or pointed out hereinafter, reference Ibeing had to the accompanying drawings forming a part' of this specification, and in which Figure l is a side eleva-tion of a channelmember of a sort which may be employed in the construction of my improved member;

Fig. la is a cross section thereof;

Fig. 12a is an end elevation of the member illustrated in Fig. 12;

Fig. 13 is a side elevation of a further modn'ication of my invention designed specically for a pole-` or a post.

Fig. 14 is a front elevation of thesame.

Referring to the drawings more specifically, the various parts `being designated throughout by similar reference characters, 1t will be understood that in the manufacture of my improved member, I mayemploy any of a wide variety of commercial structural shapes; that illustrated in Figs. l and CIT l beinga simple channel .member having a web lw and marginal flanges f. As illustrated in Fig. 2, portions of the webs ot' members of the selected form are punched out .or-slotted as shown, the displaced portions being deflected to one side ot the normal plane as shown in Figs. 2 and 3, but remaining integral with the web at one end. Two of the members so formed, which I will designate A and B respectively, arey then placed together as' illustrated in Figs. l and et", with the dellected portions s in contact, and these deflected portions or spacing strips as l will call them, are secured together, as by spot welding, or riveting, or in any other suitable fashion. The members A. and B, as is obvious, may be disposed parallel or in diverging relationship. then connected as described, the .members form a unitary structural member in which the constituent members and B are the principalv loa d carrying elements, and the spacing strips u are connections which maintain the members A and B in proper disposal and relationsliip. '.lhe structural member so vconstructed will t'orm an eli'ective strut or column, and will possess the' necessary stiffness and stability against llongitudinal stresses7 and also permit of considerable resistance to transverse and torsional stresses.

Uf course, the width and length o'l" the spacing strips may be varied as desired, as may also the degree and lorm in which they are deflected from the webs of the members A and l. However, bars formed with spacing strips 'of' a given length, may be utilized to form structural members of different radii by varying as desired the distance at which they are spaced apart and the extent to which the spacing strips are over lapped before they are connected.

.ln Figs. 5, and 7, I have shown a variety or shapes, all standard, which may be utilized. ln lfig. 5, it will be observed that instead o'f' having the spacing strips deflected from the web in the same direction as the iianges, they are deflected oppositely thereto so that in the completed member all the flanges extend outwardly.

In Fig. (i, l illustrate the use of an angle bar as the member A and an I-bcam as the member l. r

ln Fig. 7, I illustrate the use of simple plates as the members A2 and B2.

ln Fig. S, the members A and B3 are the flanges otl a specially shaped channel which is Uslniped in cross section, and the spacing strips s are punched out adjacent thc margins ot said flanges.

ln `["ig. i). lV illustrate the manner in which the spacing `:trips may be connected by rivets, and show also how they may be disposed perpendicular to the webs, or at any desired intern'iediate angle. f

ln Fig. 10, l illustrate a modification -web of the opposite member.

In Fig. l1, l show the spacing strips connected by butt welding.

ln Figs. 12 and 13, I show a construction wherein the spacing strips are longitudinally corrugated, or provided with a rib, whereby they are materially stiflened.

In Figs. 13 and 14, I illustrate an application ot' my invention wherein the members A* and B4 are portions of an integral member which is bent upon itself so as to bring its end portions opposite to each other. The connecting strips s are punched from the original member and connected ,across between the opposite portions. A cross section of Fig. 13 would be similar to Fig. 7, al` though the member, or' course, could be a channel or other shape.

In members formed in the fashion illustrated and above described, itwill be observed that two oppositely disposed members, either separate 0r integral, are used, which members provide the necessary metal to carry the stress'to which the structural member is designed to be subjected. These oppositely disposed members in my improved structure are connected by spacing strips, which strips are formed from po'rtions of the members themselves. It will be observed, moreover, that while this construction requires the use of no material in addition to the original bar members it forms a structural member of maximum strength for its weight as the deflected portions or connecting strips are taken from those parts of the bar members which are least effective in supplyingstiffness and stability. Besides producing a member having great strength and stability for the amount of material required, this form of construction materially decreases the amount of labor necessary in the manufacture of structural members designed for the use contemplated, as it is not necessary in the manufacture of; my improved structural mcmber to bolt up all of the connections pr liminary to the operation of permanently securing the constituent parts together.

It is obvious that this construction is susceptible of wide application, being useful not only as column or strut members in building constructions, but useful alsol as a reinforcement for concrete posts, beams, etc., to which uses it is particularly adapted by virtue otl the facility with which other forms of reinforcements, such as rods may be sociated with it, passed through its apcrlured portions and connected to it.

While I have shown in the drawings a number of forms in which my invention may be embodied l 'am aware, ol course, that the structure 'is susceptible to further variations, modifications `and adapta-tions without departing from the invention, the scope of which is indicated in the following claims.

What I claim is:l

1. A metallic structural element comprising side bars or load carrying members, said members having web portionsoppositely disposed, a series ot ltongues cut from said web portions and laterally deflected into coperative relation and joined together to form spacing and bracing connections between the load carrying members.

2. A metallic structural element comprising side bars or load carrying members, said members havin web portions oppositely disposed, pairs cfg tongues oppositely cut from said web portions and laterally deflected into cooperative relation and joined together to form spacing and bracing connections between the load carrying members.

3. A metallic structural element comprising side bars or load carrying members, said members having web portions oppositely disposed, a series of tongues cut from said web portions and laterally deliected into coperative relation and joined together to form spacing and bracing connections between the load carrying members, said tongues being partially cut so as to leave but one point of connection with the web.

4. A metallic structural element comprising side bars or load carrying members, said members having web portions oppositely disposed, a series of tongues cut from said web portions and laterally deflected into cooperative relation and joined together to form spacing and bracing connections between the load carrying members, said tongues bein formed with beads which operate to sti en them intermediate the load carrying members.

5. A metallic structural element comprising side bars or load carrying members disposed side by side and spaced apart and having web portions oppositely disposed, a series of tongues cut from said web portions and laterally7 deflected into cooperative relation and joined together to form spacing and bracing connections between the load carrying members.

In witness whereof I have hereunto Set my hand this 24th day of April, 1916.

J. WARREN JONES.
