FIREPROOF PARTITION FOR BUILDINGS.
SPECIFICATION forming part of Letters Patent No. 679,860, dated August 6, 1901.
Application filed April 20, 1901. Serial No. 56,735. (No model.)
To aZZ whom it may concern.-
Be it known that I, SAMUEL E. RABBITT, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Fireproof Partitions for Buildings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same.
My invention relates to the construction of buildings, has especial reference to partitions,
has for its object a fire, rat, germ, and vermin proof structure, presenting asolid composite partition of metal and plastic material,pref erably cement, which shall be as thin as practicable to secure strength and rigidity, and consists in certain improvements, which will be fully disclosed in the following specification and claims.
In the accompanying drawings, which form part of this specification, Figure l represents an elevation showing two studs in position with a section of metallic lathing attached thereto; Fig. 2, a front elevation of one of the metallic studs provided with adjustable clips for securing the lathing; Fig. 3, a vertical transverse section showing a partition in its several'stages of construction; Fig. 4, an enlarged perspective showing the construction of one end of the stud to form a foot or support therefor; Fig. 5, an elevation of a doorway in a partition; Fig. 6, a horizontal transverse section of a completed partition with the side of a door-frame at one end; Fig. 7, an enlarged perspective ofa modified construction of a foot or support for the stud especially adapted for use at the upper end thereof; Fig. 8, a like View of the coupling for the stud, whereby the stud is rendered extensible; Fig. 9, a plan View of the blank for the clip, and Fig. 10 a perspective of the blank with its sides bent for engagement with the stud.
Re'ference being had to the drawings and the letters thereon, A indicates the stud, which is preferably made of sheet metal bent upon itself to form a central rib or projection a and two side ribs b b of less height than a and forming two channels 0 a, one on each side of the rib a, to receive the plastic material and form a key, by which the plastic material is secured to the inside of the stud, and the opposite side of the stud is fiat to form a bearing-surface for the clips and the lathing, this construction of the stud being clearly shown in Figs. 4, 6, and 7. The edges d of the metal, it will be observed, engage the outside walls of the center rib a for the purpose of stiffening the stud to prevent lateral vibration of the stud while the lathing is being secured thereto.
The stud is preferably made in two sections 6 and f, connected bya sleeve-coupling B, in which the sections are movable to render the stud extensible to provide forirregularities in the joists of the floors, and on one end of the stud, preferably the upper end, a foot or support (J is formed by a section of sheet metal of single or double thickness beat, as shown at g, to fit over the rib a and split at its outer end to form laterally-extending flanges '1: i for securing the stud to upper joists by nails driven through the flanges. The bent portion of the section may be soldered to the rib a, and the flangest' 11 may be soldered to the ends of the ribs 1) b, as shown in Fig.7, or the support 0 maybe secured in any preferred manner. The form and construction of the coupling B are shown in Fig. 8, in which there are channels it is to receive the ribs 1) b and a slot Z to receive the ribs a of the adjacent ends of the sections of the stud.
Upon the fiat side of the stud are clips D, adjustably secured thereon by their flanges m' m loosely engaging the ribs 1) b, so that the clips can be readily adjusted to any degree necessary to engage the wire lathing E for securing thelathing to the fiat side of the studs by means of the fingers n n projecting through the apertures or interstices in the lathing and being bent down thereon, as shown in Figs. 1 and 3.
The lower foot or support F of the stud and upon which the weight of the structure rests while the lathing and the plastic material are being applied to the studs is formed by cutting oif'the side ribs 1) b and the metal forming the bottom of the channels a c, bending the metal of the ribs 1) and the bottom of the channel 0 up against the opposite sides of the rib a, then splitting the rib a and bending the flanges o0 laterally, with their inner faces or sides 19 resting against the ends of the ribs 1), as shown in Fig. 4, thus forming a foot of three thicknesses of metal, folded one upon the other. It is obvious that when heavy metal is used the inner fold or thickness of the ribs 2) and the bottom of the channels 0 will not be required.
In constructing metal partitions much trouble is encountered in securing the metal to door-frames to prevent its being disengaged and the plastic material being jarred or broken away from the frame by slamming the doors. To provide against this serious defeet, a wooden stud 19, extending from .the
floor to the joists of the floor above, is used, the dimensions of which are approximately two inches by seven-eighths of an inch, and on the edge thereof adjacent to the door is'secured a trimming base-piece q of thesame di mensions in cross-section, but set at a right angle to the stud p, with overlapping pro-v jections r r of a length equal to the thickness of the lathing, and the plastic material Gr forms a finish flush with the surface of the partition on both sides and provides a nailing-surface for securing the door-jamb and the trimming on each side and across the top of the doorway. The wire lathing extends across the side of the studp, as shown in Fig. 6, and the opposite side is provided with a covering 8 of wire-cloth or other metallic covering, in the meshes of which the plastic material is embedded and securely held to the stud, while the same effect is produced on the opposite side by the plastic material being embedded in the interstices of the metallic lathing. By this construction all of the doorframe in the partition is covered with fireproof material, except the trimming basepiece q, and the plastic material has a firm bearing of two inches on the sides of the stud p and prevents being broken away or jarred off by closing the door.
In the work of attaching the sheets of lathing clips t, of sheet metal, areinserted through adjacent interstices, the sheets drawn closely together,'with their serrated edges interlocked and the ends of the clips bent down around the lathing, as shown in Figs. 1 and i 3, thus joining the lathing firmly and immovextending from a floor to a ceiling'and hav ing a flat side and a plurality of ribs and grooves on the opposite side, metallic lathing,
and metallic clips securing the lathing to the flat side in combination with plastic material embedding the lathing and the studs.
3. A partition consisting of'metallic studs extending from a floor to a ceiling, metallic lathing having serrated edges, and metallic clips securing the adjacent edges of the sheets of lathing with their serrations interlocked; in combination with plastic material embedding the studs and the lathing. V
4:. A partition consisting of metallic studs and metallic lathin g, and having a door-frame formed of two members secured together at a right angle to each other with projections on each side of one member, the lathing being secured to one side of said member and the opposite side thereof provided with means .for securing plastic material thereto; in combination with plastic material embedding the studs, the lathing and one of the members of the door-frame.
5. An improved article of manufacture, a metallic stud for partitions having a flat side and a plurality of ribs and grooves on the opposite side, and provided with flanged supports at each end integral with the stud.
6. An improved article of manufacture, a metallic stud for partitions having a flat side and a plurality of ribs and grooves on the opposite side and provided with lateral supports at each end integral with the center rib of the stud.
7. An improved article of manufacture, a metallic stud for partitions having a double flat side and a plurality of double ribs on. the opposite side formed by bending a sheet of metal transversely upon itself, and havin supports'at its ends.
8. An improved article of manufacture, a metallic stud for partitions made in extensible sections con nected'by a sleeve-coupling overlapping the adjacent ends of the sections.
9. An improved article of manufacture, a metallic stud for partitions made in extensible sections, a sleeve-coupling connecting and SAMUEL RABBITT.
