D. A. BROWN March 6, 1962 STAPLE WITH LEGS HAVING NOTCI-IES AND PROJECTIONS Filed May 26, 1958 h //VI/EN7'0R-' 48 By 9W yWM V ATTORNEYS.
I United States Patent Ofiice 3,023,650 Patented Mar. 6, 1962 3,023,660 STAPLE WITH LEGS HAVING NOTCHES AND PROJECTIONS Donald Aubrey Brown, Westlake, Ohio, assignor to Donn Progglcts Incorporated, Westlake, Ohio, a corporation of '0 Filed May 26, 1958, Ser. No. 737,882 1 Claim. (Cl. 85-49) This invention relates to an improved staple-type fastener for securing wallboard to hollow metal studs of the type disclosed in my Patent No. 2,931,470. In that patent various types of fasteners have been suggested for securing the board to the studs, such as an annular nail or screw. Such connectors require more time to use because two hands are requiredone to hold the connector and one to hold the hammer for driving it into the stud.
One object of the present invention is to provide a staple adapted for use with a conventional stapling machine so that the staples may be driven through the board into the stud one after the other, very quickly, using only one hand.
Another object of the invention is to provide an improved staple construction having serrated edges which can be formed from a continuous strip of metal.
A further object is to provide a staple construction of this type which can be readily formed into clips for insertion in the magazine of a stapling machine and can be ejected therefrom without jamming.
Another object is to provide a serrated staple construction which can be produced very cheaply while at the same time providing a'positive connection for securing wallboard or the like to metal studs having slits adapted to receive the serrated staple.
These and other objects and advantages of the invention will become apparent from the following description and the accompanying drawing, wherein:
FIGURE 1 is a perspective view, partly in section, of two vertical metal studs to which wire lath is secured in accordance with the invention;
FIGURE 2 is a view similar to FIGURE 1 showing a sheet of gypsum board or the like secured to the vertical hollow metal studs;
FIGURE 3 is an enlarged perspective view, partly in section, showing the staple penetrating the slit provided therefor in the stud;
FIGURE 4 is a transverse sectional view through one of the studs showing the board secured thereto by a staple constructed in accordance with the invention;
FIGURE 5 is a sectional view taken along the line 5-5 of FIGURE 4;
FIGURE 6 is a plan view of a narrow strip of metal having serrated edges from which the staples of the invention may be formed; and
FIGURE 7 is a perspective view of a completed staple constructed in accordance with the invention, and FIG- URE 8 illustrates the two end portions of the staple and the relationship between the projections and notches in somewhat exaggerated form.
The hollow metal studs with which the staples of the invention cooperate may be made from a single piece of sheet metal which has been bent to form a pair of generally triangular hollow beams 10, 12 interconnected with a central web 14. The studs are of suitable dimension and thickness to stand considerable compressive load and are intended to replace the conventional 2 x 4 studs commonly used in residential and commercial building. The webs of the studs are provided with openings 16 formed by cutting out the tongue 17 and bending it over against the central web member just below the opening. These openings 16 are conveniently located for passing conduits,
wiring and the like through the walls. They may also be used to support conduits within the walls.
The hollow triangular beam members 10, 12 are joined to the Web at their apices by a double reverse bend in the sheet of metal which locks the free end of the sheet to provide a continuous triangular enclosure. By means of this construction the stud comprising both hollow triangular members and the central web may be fabricated from a single sheet of metal. The base of the hollow triangular beams 10, 12 is deformed to provide a central V- shaped groove 30 having side walls 26, 28 which are parallel to the outer walls of the triangular beam. The bottom of the groove contains a multiplicity of longitudinal slits 32 which are separated from each other with land 34. These slits extend along the entire length of the stud and serve to receive the staples. The outer portions 22, 24 of the base, disposed on either side of the groove 39, provide a planar support for the wallboard secured thereto. It will be understood that the triangular beams 1t 12 of the stud are identical in construction. This permits sheathing to be secured to both sides of the stud to form a complete Wall.
Staples 49 constructed in accordance with the invention are adapted to secure wire lath, gypsum board, rock lath, plywood or the like to the studs, as shown in FIGURES 1 and 2. The staples are made from a flat, narrow strip of metal 42 having both edges serrated, as shown in FIGURE 6. The serrated edges are continuously uniform, Without variation or discontinuity in the alternate notches and projections which extend along the entire length of each staple. The metal is preferably cold-rolled steel which has been zinc coated or otherwise treated to prevent corrosion. The metal should be sufficiently thick to resist bending as the staple penetrates the wallboard and the slit in the stud. The serrations in both edges of the metal strip comprise alternate notches 44 and projections 46. It will be noted that the projections 46 are wider than the notches 44. This is a very important feature of the invention. For use, the staples must be inserted in the magazine of a stapling machine. To do this conveniently they are arranged side by side to form a clip. If the notches are the same size as the projections or wider than the projections, adjacent staples in the clip will lock together and cause the stapling machine to jam. By making the projections or the land wider than the notches, as shown most clearly in FIGURE 8, interlocking of the staples is prevented. Moreover, in cutting the serrations it is necessary to locate each projection opposite a notch to prevent the formation of a narrow neck as where two notches are opposed. This avoids a point of weakness.
It will be further noted that the serrations of the preferred construction illustrated are square or rectangular rather than arrow-shaped, as suggested in the prior art. Unlike the arrow-shaped barbs, the square serrations do not require the staple to be driven into the slit of the stud in any particular direction. It will be appreciated that barbs require the staple to be inserted with the pointed ends leading. This requires that the staples be cut individually from a fiat sheet with the barbs pointing in opposite directions. By using the serration construction of the invention the staples may be severed indiscriminately from a continuous length of strip material, the edges of which have been previously serrated without taking any care as to the location of the serrations with respect to the cut-oil point. The staple stock is automatically cut in predetermined lengths from a continuous strip 42 and bent into the U shape shown in FIGURE 7. An X-shaped die is used to cut off each length of staple stock, thereby forming points 48 at the ends to 3 facilitate penetration by the staple of the sheathing and slit 32 in the hollow stud.
The staples may be conveniently formed into a clip by aligning them in the desired manner and applying an adhesive film over the bridge of each of the staples. The continuous film permits the staples to be handled, shipped and inserted in the magazine of the stapling machine as a unit rather than individually. If desired, the staples can be mechanically adhered by deforming the bridge portions laterally to provide complementary notches and re cesses or the like for detachably securing the adjacent staples together. It has been found that the staples of the invention can be driven very rapidly from a conventional staple machine without jamming. The wide projeotions 46 allow them to slide over each other.
In FIGURE 1 wire lath 50 is shown secured to the studs by means of the staples 40. It will be noted that the lath may be secured to both sides of the studs to form a unitary wall structure. A base channel 51 may be provided for supporting the bottom of the studs and for causing them to be accurately aligned at the location of the wall. The outside of the metal lath is plastered in conventional fashion with a layer of plaster, designated in the drawing by the numeral 52.
In FIGURE 2 I have shown gypsum board 54 secured to the studs by means of staples 40. The staples will penerated the gypsum board without difficulty. The leading edge of the staple penetrates the slit 32, pushing aside the walls 26, 28 to provide a solid connection.
The land 34 between the slits insures a positive resilient.
grip because it limits the expansion of the slit 32. On those rare occasions where one leg of the staple may strike the land 34, it will break. The land portions are located frequently enough so that even if one breaks the ability of the edges of the slit to hug the staple is not impaired. From FIGURE 4 it will be noted howthe edges of the walls 26, 28 forming the slit are disposed in the notches 44 to lock the staple so that it 4 cannot pull out of the stud without application of considerable force.
Thus, by means of the present invention it is possible to fabricate very rapidly a fire-proof wall.
Although -I have shown and described a preferred form of my invention, it will be understood that various modifications may be made in the construction without departing from the true spirit and scope of the invention. For example, the staples shown and described are not necessarily limited to use with metal studs but can be used with Wood. The serrations cause the staples to become embedded tenaciously in the wood because the fibers tend to move in behind the serrations. It is, therefore, my intention not to limit my invention other than as necessitated by the scope of the claim.
What I claim is:
An improved staple for securing sheathing to ahollow metal stud having a resilient slit for receiving said staple comprising a fiat, narrow strip formed of sheet metal bent into U shape and having continuously uniform serrated edges consisting of alternate rectangular notches and projections, the notches along one edge being opposed by projections along the other edge, said projections being wider than said notches.
