UNITED STATES PATENT OFFICE.
ALBERT L. CLAPP, OF MARBLEHEAD, MASSACHUSETTS, ASSIGNOR TO THE FLINTKOTE COMPANY, OF BOSTON, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS.
CORNER BEAD AND METHOD OF MAKING THE SAME.
Application filed October 2, 1919.
T (.iZZ whom it may concern:
Be it known that I, ALBERT L. CLAPP, a citizen of the United States, residing at Marblehead, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in Corner Beads and Methods of Making the Same, of which the following is a specification.
This invention has for its object to provide a novel corner bead and a method of making the same.
In accordance with the invention, the corner bead is made of molded waterproof fiber, the rib being stiff and unyielding, so
as to preserve the line of the corner, and
the wings being preferably more or less flexible so as to accommodate inequalities in the surfaces against which they are secured.
On the accompanying drawings,
Figure 1 represents a portion of a blank from which the corner bead is to be produced.
Figure 2 represents the same after it has been striped with a coating of waterproof adhesive material, and crushed mineral has been more or less embedded in the coating.
Figure 3 represents conventionally a sec tion on the line 3-3 of Figure 2.
Figure 4 represents a section through the molding devices, and illustrates how the corner bead is formed by molding.
Figure 5 illustrates a finished corner bead.
As the starting material, I employ a fairly thick sheet of fibrous material containing an appreciable quantity of asphalt or equivalent waterproofin stiffening compound, which is rendered p stic by heat, but which, under normal atmospheric conditions, is relatively hard and stiff. For example, I may use a paper felt, such as is employed in the manufacture of prepared roofing, and saturate or impregnate it with a high-meltingpoint asphalt or pitch or equivalent waterproofing compound, while such compound is heated to a liquid state. or else I preferably employ a like paper felt but in which the asphalt of relatively high melting point is incorporated by any approved process, in the initial formation of the sheet. In the lastmentioned case, the contained asphalt or pitch is caused to coalesce when the sheet is subjected to a sufficient degree of heat or to high ressure.
- n igure 1 there is illustrated a sheet of Serial No. 328,079.
asphaltor pitch-containing material, which is preferably cut in lengths of say six to ten feet and about five inches (more or less) wide. The middle of the strip is preferably coated with a longitudinal stripe b of high-melting-point pitch or asphalt, in which is partially embedded a facing a of crushed or powdered slate, grit or other mineral material. Both faces of the strip a may be thus striped and faced. The strip thus formed is now ready fOr molding into final form as a corner bead. Any suitable molding apparatus may be employed. I have shown a mold consisting of four elements or sections, namely a bottom section 6 being triangular in cross section, side sections 7 7, and a top section 8. The strip is folded along a median longitudinal line and placed on the section 6, and the two side sections 7, 7 are moved towards each other and the section 6, after which the top section 8 is forced 'downwardly. The resulting product is a corner bead having the side wings or attaching members d, d, the corner rib e, and the bead or enlargement f at the outer edge of the rib. The sections 7, 7, of the mold have faces 1O, 10, which force the side portions of the folded strip against the sides of the section 6, but at 9, 9, they have parallel faces, at an obtuse angle to the faces 10, 10,
which have the effect of folding the strip into the rib e. Said sections 7, 7, have the segmental concave faces 11, 11, which cooperate with the semi-cylindrical groove or concave face 12 in the top mold, in forming the bead f at the edge of the rib. The pressure of the mold sections is suflicient not only to compact the wings (Z d, but to crowd the contacting portions of the rib together with suchpressure that they form practically a solid mass, the asphalt or pitch in and on the surface of the material coalescing. The grit or sand, which constituted the facing, is solidly embedded in the pitch or asphalt, and imparts inflexibility and rigidity to the rib and bead.
Under some circumstances, the asphalt coating and grit facing ma cover the entire face of the strip, but I pre er that the stripe formed on the initial strip shall be wide enough to include only those parallel zones of the stri which subse uently constitute the rib an the bead, as l regard it as deeirable that the wings of the finished article 2 inst-1,745
should have a limited flexibility. The rib is inflexible and rigid, and its surface is more or less rough owing to the embedded sand and grit. v The article is inexpensive in construction and is durable, not having the iniirmities of the usual metal corner bead, since it is waterproof and. is not affected by moisture and dampness; Of course, it desired, both the rib and the wings may be formed with the usual holes or openings topermit the keying of the plaster.
Having thus explained" the nature oi. my said invention and described a way of malt ing and using the same, although without at tempting to set forth all of the forms in which it may be made or all of the modes oh its use, what I claim is 1. A corner bead consisting of a water proof fibrous material containing a waterproofing stiffening material and having a rigid rib, and an attaching wing angular thereto.
i 2. A corner bead consisting of a. molded fibrous material containing asphalt, and comprising a thick substantially rigid in tegral rib, and thinner and more flexible Wings '01 attaching portions extending from Said rib atan angle thereto.
3. A corner bead consisting of a fibrous material impregnated with a bituminous stiffening compound, and comprising a substantially rigid rib and semi-flexible wings or attaching portions.
i. A corner bead consisting of asphaltcontaining fibrous material and comprising a rigid rib and more flexible attaching means angular to said rib.
5,. A corner bead comprising a rib and angular attaching wings, said head consistingof asphalt-containing fibrous material, and said rib being provided with a material for ensuring, its rigidity. I V
6. corner bead comprising a rib and attaching wings, said bead consisting of asphalt-containing fibrous material, and said rib having a granular material embedded therein for increasing its rigidity.
7. A corner bead comprising a rib and at taching wings, said head consisting of asphalt-containing fibrous material, and said rib having an external layer oi asphalt with a mineral material embedded. therein.
8. A corner bead comprising a rib and attaching wings, said bead consisting of a molded strip of asphalt-containing fibrous material, and said rib containing a stitlening material. i i
9. A corner bead comprising a rib and attaching wings, said bead consisting of a strip of asphalt-containing fibrous material said rib being compacted and containing a stiffening material.
10. A corner bead comprising a rib and angular attaching wings, said bead comprising a strip of asphalt-containing fibrous ma.- terial doubled substantially on its median line to constitute said rib and with its marginal portions at an angle to constitute said wings, said rib being united and compacted to substantially rigid condition.
11. The herein described method of making corner beads which consists in doubling a fibrous material containing a Waterproof stiffening compound on a longitudinal line, and by pressure molding said doubled portions to form a. unitary rib and divergent wings. v V
12. The herein described method of making corner beads which consists in applying amedian strip oi asphalt to a strip of fibrous material containing a waterproof plastic compound, embedding a stiffening material in said. strip, doubling said strip on a median line, and by pressure molding said doubled portion to form a unitary rib and divergent- Wings.
In testimony whereof I have atlixed my signature.
ALBERT L. CLAPP.
