SHEET-METAL STUDDING- SPEGIFICATIOK forming part of Letters Patent No. 754,270, dated March 8, 1904. v

' Application filed May 27,1903. Serial a... 158,920. (a. model.)

To all whom it may concerm Be it known that we, HENRY WITTEKIND and ROBERT ,E. BOURKE, citizens of the United 'States, residing at Chicago, county of Cook,

State of Illinois, have invented a certain new and useful Improvement in Sheet-Metal Studding; and we declare the following to bee. full,

clear, and exact description of the invention,

I such as will enable others skilled in the art to which it pertains to make and use the same, reference beinghad to the accompanying drawings,

Our invention relates in general to members used in the erection of buildings-such as roofjoists, floor-joists, scantling, or studdingand more particularly t5 sheet-metal building members. v

In order that buildings may be thoroughly fireproof, it is desirable to use in their construction metallic joists and studding and to secure to the studding metallic lathing upon which the plaster is supported. The employdered it necessary that provision be made for ment of metal studding, and lathing has renenabling the lathing to be readily and securely fastened to the studding.

The primary object of our invention is to provide a metallic building member to which the lathing or other structural members may be l'eadily and securely fastened by the use of nai s. 1 a

A further object of our invention is to provide a building member composed of sheet metal which willbe light and simple in construction, inexpensive in manufacture, and

strong and durablein use.

, 'Our invention, generally described, consists in a building member formed of sheet metal the web of which comprises two or more thicknesses of metal between which at one edge an additional thickness of metal extendsa short distance, thereby enabling nails to be driven between the two thicknesses of the web and retained therein through engagement of the edge of Y the inwardly-extending short thickness with the nails, the latter being preferably barbed to render such engagementpositive and secure.

Our invention will be more fullydescribedhereinafter with reference to the accompanying drawings, in which the same is illustrated which form a part of this specification;

such, for-instance, as rivets 0.

cal forms, and in which as embodied in several convenientand practi- 1 Figure 1 is a cross-section of a member comprising a web and oppositely-extending flanges at each end thereof; Fig. 2, a cross-section of a member in Y which oppositely e extending flanges are provided only at one end of the web; Fig. 3,- a view similar to Fig. 1, in which the two parts composing a member are reinforced by channel-beams; Fig. 4, a cross-section of a member in which a single flange is provided extending inone directionfrom one end of the web; Fig. 5, a View similar to Fig.

4, in which a single flange extends from each end of the web and in the same direction; and

Fig. 6, a view similar to Fig. 5, in which a single flange is provided at each end of the web, such flanges extending in opposite direc: tions.

Similar reference characters are used to indicate similar parts in the several figures of the drawings.

. Reference characters A and B, referring particularly to Fig. 1, indicate two similar parts united by means of rivets c to form the building'member. The part A of the member comprises a web at the ends ofwhich extend in the same direction flanges a a, formed of two thicknesses of metal, such thicknesses being bent around-and lying adjacent tothe .web, as indicated at a a. The part B is simi-' lar to the part A and consists in a web at the opposite ends of which extend flanges b 12, formed of two thicknesses of metal, which extend around the web a short distance,as shown atbb.

D indicates a nail driven between the two thicknesses of the web of the member shown in Fig. 1 for the purpose of securing lathing or other structural members. The nail is shown as barbed, thereby renderingit's retention between the two thicknesses of the web secure and positive throughthe engagement of the barbs with the edges of the inwardlyextending-thicknesses of metal a and b. I

In-Fig. 2, A

and B indicate the two parts of-the building member, which are secured together by any suitable fication flanges a? and b extend in opposite fastening devices- -11), thismodil of the web. The webs a and F are, as in Fig.

I tween the two parts of thewebto form nail-re- 1, made of two thicknesses of metal which terminate between the two parts of the web to form short thicknesses of metal a and b, the edges of which retain the nails in position.

The modification shown in 3 is similar to that shown in Fig. 1 except that reinforc ing channel-bars E and F are surrounded by the metal composing the two parts A and B These channel-bars need not of the member. necessarily-be whatare technically known as channel-beams, but may be thinsu ch, for instance, as sheet metal bent to the channel 'form.

of two parts A and A, united by rivetsjc to form a web between which nails may be driven. ,Only-one of the partsnamely, B is provided with aflange b. Inwardly-e x what we claim'as new, and desire to securejiby Letters Patent, is-

tending thicknesses of metal are, however, provided between the two partsgof the web'to In Fig. 5 we have illustrated a modification similar to Fig. 4 except-that parallel flanges b extend in the same direction from the oppor hers "are adapted tzbe' driven, the opposite.

site ends of the member B. The member-A is, however, provided with inturned thick-' nesses of metal which cooperate with inturned thicknesses of metal to form nail-retaining" e s The embodimentof our invention shown in Fig. 6 consists in two parts A and B, united by rivets a to form a web composed of two thicknesses, at each end ofwhich is located a flange,such flanges a and 6' extending in op posite directions. As in the other 'embodiments of our invention, short inturned thicknesses of metal extend between the two thicknesses of the web to form nail-retaining edges.

" The mannerof usingour invention will be readily understood by those skilled in'the art from the foregoing description. The member is secured in" the desired position in the building and in the desired relation with the other cooperating members. Thelathing or other structural members may then be readily se-- cured to our improved building'member by merely driving nails through the-lathing and between the two thicknesses of the web, the nails being of such .alength that the endsthereof project inwardly beyond the retaining "edges of the inturnedjshort thicknesses of' metal, and are thereby securely locked between the parts of "the web. The twoIthicknesses of the web may be closely by means of the rivets without preventing the driving of nails between the same, inasmuch as the distances between the rivets are such that the resiliency oi the metal permits'the separation of the two thicknesses sufliciently to enable the nails to be driven between the It isevident from the foregoing description that we have invented an improved sheet-metal building member which is light andat the v same time strong structurally and which contains provision. for the ready attachment thereto by the use of V nails, staples, or other fastening deviceslathing orother cooperating structural members. a

While we have illustrated anumber-of embodiments of our invention, we do not wish to be understood as limiting'ourselves thereto,

as the invention is capable of a variety ofembodiments. We consider any sheet-metal 1 building memberas coming within the scope of our. invention which consists in a web I formed of two thicknesses of metal between which at one end extends an addition'aLshort thickness of metahthereby forming aretain ping edge toengage a nail or other fastening device driven between the time thicknesses of y 1 i -Having now fully. described our invention,

1. A sheet-metal building member comp rise "ing a web formed of two parts rigidly united tog'ether between which fastening devices for securing thereto cooperating .building memedgesof one of said arts terminating in portions extending in ardly, between the two parts composing theweb, the edges of such portions adapted to engage and retain the fas- TOO tening devices between the two parts of the 7 web. 1 a

2. A sheet-metal building member comprising a .web formed of two parts rigidly united togethen between which fastening devices for securing thereto cooperating building membersare-adapted to be inserted, the opposite ends of each part terminating in portions extending inwardly between the two parts composing 'the web, thereby forming locking V edges at each end of the webto retain therein the inserted fastening devices.

' 3. Asheet-metalbuildingmember comprise ing a' web formed of two parts rigidly riveted together, a flange formed at each'end of each part of said web each of said flanges com osed terminating in a portion extending inwardly of a plurality, of thicknesses of metal an each between the two parts of the web thereby forming locking edges at each end of the web to retain fastening devices therein.

In testimony whereof we sign this specifica: I

tion in the presence of two witnesses.
