HON/'5 fer United States Patent 3,412,512 PARTITION CONSTRUCTION EMPLOYING DOUBLE CORNER BEAD Harry W. Hollister, 89 Thayer St., New York, N. 10040 Filed July 6, 1967, Ser. No. 651,606 9 Claims. (Cl. 52-239) ABSTRACT OF THE DISCLOSURE The disclosure describes a partition structure in which a free end or edge of the partition has a bead or molding embedded in plaster and formed with dual ribs defining parallel spaced corners. The ribs are V-shaped and are integrally joined by a narrow web defining a recess to receive plaster. A side flange is integrally joined to one panel of one rib. The ribs, web and flange are all apertured to receive plaster keys and nails, clips or wires for laths. Slits can be formed in the bead defining tongues or prongs which can be twisted in or out to engage wire lath, frame bars, and other parts of a partition.

The objects of the invention are to provide quick, inexpensive, time and labor saving ways of forming any of the following structures among others:

(1) A vertical or horizontal end or edge of a partition in a room.

(2) The bottom edge of a curtain wall.

(3,) The top and side edges of a vertical dwarf partition which does not reach a ceiling.

(4) Means for reducing a wide partition to a narrow partition against a window mullion.

(5) Means defining the top interior angle of a light cove between vertical wall and horizontal ceiling.

(6) A window frame with square or chamfered edges, and with straight or curved top.

(7) A door frame in a wall, the door frame being prefabricated or made on site and having a straight or curved top.

(8) A top or bottom rail in the lath partition.

(9) A plastered opening in a wall with a straight or curved top.

(10) The corner or end of a ceiling where there is another higher ceiling above it.

(11) A drop ceiling structure where a ceiling at the top is plaster and the suspended ceiling is made of acoustic tile or blocks.

(12) The bottom corner of a short vertical partition and integral ceiling.

The invention involves installation of a double corner bead or molding where closely spaced parallel corners are needed. Heretofore, separate corner beads or moldings have been used for this purpose. It is extremely difficult and time consuming to install separate beads in true parallelism. Often it is not possible at all. With the present invention two corners are constructed simultaneously in a rigid, solid, double bead construction which is mechanically perfect, which accepts a neat finish and which can be mitered quickly if required. Connect beads in long run horizontally such as a curtain wall with nails or to form a plastered opening with nails also.

For further comprehension of the invention and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

FIGURE 1 is a fragmentary perspective view of a ice partition structure according to the invention, parts being shown broken away to show internal construction.

FIG. 2 is an enlarged horizontal sectional view taken on line 2-2 of FIG. 1.

FIG. 3 is a perspective view of part of a bead or molding with double ribs, central web and single side plate.

FIG, 4 is an end view of the bead or molding with an associated clip used to anchor one end of the bead.

FIG. 5 is a perspective view of the anchor clip per se.

FIG. 6 is a vertical fragmentary sectional view of a partition structure including an upper ceiling, a curtain wall or partition, and an end of a suspended or drop ceiling.

FIG. 7 is a fragmentary perspective view with parts broken away of another partition structure according to the invention.

Referring first to FIGS. 1 and 2, there is shown a partition 10. This partition has an end or edge 11 which can be the edge of a window opening or doorway for the free standing end edge. The partition has an interior frame defined by rigid stationary vertical bars or rail 12 and horizontal bars 14. The bars 12, 14 are held together by wire ties 16. Expanded wire laths 18 and 19 is applied to opposite sides of the frame and is secured by further wire ties 16'. At the end 11 of the partition is a vertical head or molding 25 extending the full length of the partition.

Bead 25 as shown to best advantage in FIGS. 2 and 3 has a pair of V-shaped ribs 26 and 27 defined by two pairs of panels 28, 29 and 30, 31. The apices of the ribs are rounded to define narrow ridges 32 which stiffen the structure. Inner adjacent edges 34 of panels 28 and 30 are integrally joined by a narrow web 36. A shallow, generally, V-shaped external recess 38 is defined by web 36 and panels 28, 30 angularly disposed to the web. Recess 38 is filled with plaster 40. Integral with panel 28 and bent at an obtuse angle thereto at fold 42 is a side plate or flange 44. Flange 44 extends parallel to the plane of the bars 12 and 14 and wire laths 18, 19. Flange 44 is spaced inwardly of the outer side 45 of the partition due to the angular disposition of panel 28 to panel 29. The ribs 26 and 27 have medial planes extending diagonally of the end surface 46 of the partition. This provides a very strong, rigid structure. The wire lath 19 extends along the outer side of panel 31. Wire lath 18 extends along the outer side of flange 44. Holes 50 are formed in all the panels 28-31, web 36 and flange 44. Suitable clips, nails, wire ties, such as wire tie 16" can be inserted through these holes for holding the wire lath, end rail 12 and bead 25 together. The holes also serve to receive plaster keys 54. Ground and finish coats 55 and 56 adhere to the wire laths 18 and 19 and complete both sides of the partition.

The bottom end of the bead can be anchored to a clip 60. This clip as best shown in FIGS. 2-5 has a rectangular flange 62 provided with holes 63 which can receive bolts, nails or screws 64 to secure it to a solid footing such as a floor. If the head 25 terminates at its upper end at a ceiling, then a similar clip 60 can be used to anchor the upper end of the head. The clip has a bifurcated end flange 66 provided with two prongs 68 in a V-shaped array. The prongs fit into the V-shaped ribs 26, 27 of the bead. Flange 66 is offset from the plane of flange 64 by a narrow step 69 to insure engagement with the interior sides of the ribs. Ends of bar 12' can abut steps 69. The flanges 64 and 66 are laterally ext nded so that edge 67 is aligned with a ridge 32. This provides a wide footing for the clip since the lateral extension of the flanges clears the bead 25 just beyond panel 31 of rib 27.

The construction of end 11 of the partition is strong and rigid. Its corners 11 are straight and perfectly parallel throughout. If these corners had been made by individual, separate beads as heretofore practiced, it so would have been difficult or impossible to align them so that their corners would be as perfectly parallel.

The beneficial eflects of this construction flow from construction of the bead 25. This structure can be made of metal or plastic by conventional material working machinery. The bead 25 can be extruded by continuous bead extrusion machinery at very low cost. Then it can be cut into desired lengths. Holes can be punched wherever desired. The holes can be circular, square or of any other desired geometrical shape. Triangular holes are often desirable since they grip wires 16" more securely holding the lath by wedging the wire into corners of the holes. The bead 25 can be extruded or molded in a curved shape lengthwise for forming a curved archway or curved top of a doorway or window opening.

FIG. 6 shows another partition structure in which a drop ceiling 70 is supported by a curtain wall or partition A. The drop ceiling is formed of acoustic, sound absorbing tiles 72, one part of one such tile being shown. The tiles 72 have a narrow groove or kerf 74 formed in one side edge 73. In this groove extends narrow horizontal flange 75 of an angle rail 76. The rail has a vertical flange 78 secured by nails 79 or otherwise to plaster side 80 of partition 10A. This partition has spaced vertical bars 82 secured at upper ends in upper ceiling 86. Bars 82 have holes 83 in which wire ties 84 are engaged and hold vertical wire lath 86 and 87. Plaster sides 80 and 81 of the partition are secured to the wire lath 86, 87. If desired one lath 86 or 87 can be omitted and the plaster can be secured to the remaining wire lath.

The bottom edge 11a of partition 10A is reinforced and defined by a bead 25 of suflicient length to extend from one vertical wall 90 to the opposite wall of the room or building where the partition structure is installed. Parts of partition 10A corresponding to partition 10 are identically numbered. Tiles 72 are further supported by conventional hangers (not shown) from ceiling 85.

FIG. 7 shows another partition structure 10B in which parts corresponding to partitions 10 and 10A are identically numbered. All the panels 2831', web 36 and flange 44 of bead 25a have rectangular holes 50a. Adjacent the holes are slits 92 defining pairs of prongs 94. These prongs can be pushed outwardly to lock with the plaster sides and end of the partition. They also lock with the wire lath 18 and 19'. They can even be bent to engage with the frame bars 14. Holes 52a can be triangular or of other geometrical shape.

Partition structures 10, 10A and 10B are just three of many possible ways of practicing the invention. The versatility and adaptability of the double corner bead structure makes it possible to construct partitions and partition openings in an almost unlimited range of lengths, widths and depths.
