SPEGIFICATION forming part of Letters Patent No. 717,923, dated January 6, 1903.

Application filed October 17,1900. Serial No. 33,348. (No model.)

To (LZZ whom it ntay concern:

Be it known that I, JOHN W. RAPP, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Studding, of which the following is a specification.

My invention relates to studding, and particularly to metallic studding for use in forming partitions, such as walls, ceilings, &c.

I will describe several forms of studding each embodying my invention and then point out the novel features in the claims.

In the accompanying drawings, Figures 1, 2, 3, 4, 5, 6, and 7 are perspective views of various forms of studding each embodying my invention. Figs. 8 and 9 are each detail perspective views of a portion of a partition or wall embodying my invention. Fig. 10 is a detail perspective View of a portion of a ceiling and embodying my invention.

Similar letters of reference designate corresponding parts in all of the figures.

, Referring now more particularly to Figs. 1 to 7, A represents a stud which is made from sheet metal. The stud A comprises a longitudinal loop portion a, which has an opening also extending longitudinally of the stud, and flange portions a, provided at the edges of the loop at. These flange portions need not be continuous. The longitudinal opening is produced by reason of the sides being separate one from the other. The loop is adapted to receive a portion of a fastening devicefor example, a nail--and the fastening device is held and clamped by the edges 01 and sometimes by the edges and sides of the loop. The sides of the loop are preferably continued to form the flanges, and the sides are bent at a to form the flanges. The rounded surfaces caused by the bending serve in a measure to guide the nail or other fastening device between theedges of the loop. The loop a of the stud is of varying widths and has the function of a spring-that is to say, the sides of the loop tend to return to normal position after they have been spread or forced apart and hence the edges, or the edges and that portion of the sides which contact with the fastening means, serve to clamp, bind, or hold the fastening means. This resiliency or elasticity is inherent in the metal used in the formation of the studdiug. The loop may have any form. It may be flat at that portion diametrically opposite its open portion, as shown in Figs. 1, 2, 5, and 6, or it may be rounded, as shown in Figs. 3, 4, and 7. The sides of the loop may be inclined to= ward each other, as shown in Figs. 1, 4, 5, and 7, or they may be inclined toward each other for a portion of their width and then be parallel for another portion of their width, as shown in Figs. 2 and 7, or they may be wholly parallel from the ends of their flat or rounded portion, as shown in Fig. 3. A shoulder a may also be provided in the side portions, as shown in Figs. 2 and 6. The metal in the stud may also be corrugated in one or more directions, if desired, as shown in Figs. 1 and 2, the purpose of this being to permit of a better clenching by the sides of the loop of the fastening device. The flanges a serve as bearingsurfaces for the material that is to be secured to the stud. In the instance shown in Figs. 8 and 9 the material is shown asbeing wire lath B. The fastening devices employed for securing the lath to the stud, on one side thereof, are shown here as consisting of nails (3,which are bent to form hooks. Staples or any other device may be used. Nails may also be used to secure the lath to the opposite face of the stud, as shown in Fig. 7. In this instance cuts or slits a are made in the loop, into which the nails are driven. The edges of the cut or slit serve to retain the nails in them. Instead of forming cuts or slits in the loop and employing nails I cut the metal of the loop in such manner as to form tangs of", under which the lath is inserted. These tangs may also be bent out of the plane of the metal from which they were cut and bent in any other direction to secure the wire lath to the studdiug. After the wire lath has been secured in place plaster or plasterboard or any other substance D is applied to the wire lath. The studding is secured at its ends to other supports in any desired manner.

In the formation of ceilings (see Fig. 10) I preferably employ studding the loops of which have a flat portion, for the reason that a firm bearing can be made where it passes under and contacts with the I-beams E, employed for supporting the floors. The studding is secured to and suspended from the I beams by means of the tangs a. The plaster or other fireproof board D is then put in place on the flanges. The inclined sides of the loop serve to retain the board D on the flanges. I prefer, however, to use the form of stud shown in Fig. 6, for the reason that the shoulder a acts effectively to retain the plaster or other board in position. \Vire or other lath may be fastened to the studding suspended from the I-beams and plaster applied to the lath.

to be held, and tangs formed in said loop for the purposes described.

3. A stud for partitions comprising a longitudinal loop portion having a longitudinal openingin which a fastening device is adapted to be held, longitudinal shoulders provided at the loop portion, flanges, and tangs formed in said loop portion.

4. A stud for partitions, comprising a longitudinal loop portion having a longitudinal opening, said loop portion being formed with shoulders, and the sides of the loop being parallel with each other for a portion of their length, and means provided in said loop by which Wire or other lath may be secured to it.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN W. RAPP.
