' GEORGE S. KNAPP, OF CHICAGO, ILLINOIS, ASSIGNOR 'TO KNAPP BROS MANUFACTURING COMPANY, A CORPORATION OF ILLINOIS.
Specification of Letters Patent.
Patented Feb. 19, 1907.
Application filed March 21. 1906. Serial No. 307,248.
To all whomjt-may concern.-
Be it known that I, GEORGE S. KNAPP, a
citizen of the United States, residing in Chicago, in the county of Cook and State of Illinols, have invented certain new and useful Im rovements in Metal Corner-Beads; and I do ereby declare the following to be a full, clear, and exact description of the invention, such as will enable those skilled in the'art to which it app'ertains to make and use the same. My invention relates to improvements in metal corner-beads, and particularly'to corner-beads made of one piece of sheet metal doubled back upon itself on a central longitudinal line.
Oneof the salient objects of my invention is to provide a cheap, efiicient, and simple metal corner-bead structure of. the class specified, easy of manufacture and which can readily be attached to a relatively distant supporting structure or construction to afford a true plumb corner-surface irrespective of variation in the support or constructionfrom a true vertical line.
Other and further objects of my invention Wlll become apparent to those skilled in the art from the following description, taken in conjunction with the accompanying drawings,
wherein- Figure 1 isa perspective view of a corner bead embodying my invention. 2 is a transverse section of m corner-bead applied in a wall structure, anc Fig. 3 is a plan view of the blank before bending.
Throughout the drawings like numerals of In the drawings, 5 indicates the head of the bead, preferably formed by bending the undiating from the head.
interrupted central portion of the blank (shown in Fig. 3) upon itself into C shape, and 6 6 represent wings integral with and Pa- These wings'start frem the head in such relation as to include opposite sides are preferably aired or arranged in lateral alinement, an on eachside the fingers are preferably spaced apart b distances approximately equaling the widt of a blade, said fingers being by reason of their .lengthand slenderness relatively 'springy at Nail-holes 8 8 are prefertheir extremities. ably provided in the free extremities of the fin ers 7 to receive the attaching-nails 9.
In the formation of my improved comerbead the structure is first blanked out of a sheet of metal in the form shown in Fig. 3 and thereafter bent up or foldedlongitudinally in the configuration shown in Fig. 1. It will be observed that since the fingers are preferably spaced apart by distances equal to the width of the fingers a minimum waste in material in manufacture is incurred, and the parts out out to form the spaces of fingers in one strip constitute the fingers of the next I adjoining strip.
In the use of corner-beads as heretofore made difficulty is experienced in the fastening of the bead to the'construction or supporting structure, owing to the fact that the studding or other construction-work is apt to be uneven, irregular, or out of plumb, and, further, it is often quite distant from the cornerline of the plastering. With many metal corner-beads commonly employed in practice the attaching structures are relatively narrow, stiff, and arranged at a predetermined angle, usually ninet degrees, which necessitates their being app 'ed in very close conformity to the corner ofthe studding or construction, so that the heads or noses of the beads are difficult to plumb, and for attachment to distant construction the use of attaching-wires or removable clips isnecessitated, at increased expense and large expenditure of time. These difficulties my invention overcomes, as the' long fingers are in practice attached to the studding or other construction by nails 9 at a considerable distance from t e corner of the construction and from the head of the head, so that com: parativel wide variation from plumb in the edge of t e construction will have no effect upon the bead, and, furthermore, exact adjustment of the bead as to location and plumb may readily be obtained in virtue of the resilience of the bead and fingers and the resultant ease with which the bead in course of'application responds to manipulation of the party applying it.
Also it will be observed the independent interspaced andrelatively numerous fingers enable the facile attachment of the beadlng With firrn secure bearing and anchorage irrespectiveoi' sharp irregularities in the surfaces of the construction. without resort to any makeshifts of suspension attaching-wires, clips, or the like, and the increasing angular opening between the op osite fingers prepares the bead normally'ror attachment to the construction in proper relation to position the head at a distancefrom the construction easily variable to compensate for any desired thickness of plaster.
Having thus described my invention, What I claim, and desire to secure by Letters Patent of the United States, is-
1. A device of the character described, com rising in its structure a continuous longitu inal, folded head, and a series of iong, slender, resilient fingers directly radiating from the head on opposite sides.
2. A device of the character described,
gitudinal, C-shaped head, and a series of'long,
slender, resilient fingers, integral with the head and radiating therefrom on opposite sides at an angle of less than ninety degrees, said fingers being curved outwardly vto a'p proxirnatelyright-angle relation at their extrenntles.
3. A device of the character described, formed of a unitary sheet of sheet metal, cut to provide on opposite sides relatively long, slender fingers, extending outwardly'froma central uninterrupted strip, said-central strip being bent to provide a longitudinal, continixous, folded head, and Wings radiating therefrom at an angle of less than ninety degrees to each other, the fingers being curved apart to approximately right anglesto each other at their extremities.
