IMPROVEMENT IN METALLIC LATHING.

' Specification forming part of Letters Patent No.l22,171, dated December 26, 1871; antedated December 9, 1871.

'To all whom it may concern.-

Be it known that i, ISAAC v. HOLMES, of the city, county, and State of New York, have i11- vented 'a new and Improved Mode of Fastening Metallic Laths to the supports of the saine, as used in the construction of nre-proof walls; and I dol hereby declare that the following is a full and exact description thereof, reference being had to f the accompanping drawing and to the letters marked thereon making part of this specification.

The nature of my invention consists in a coinbination of metallic supports or studs with ine tallic lathing, used in the construction.ofwalls for houses and other like structures, in such a manner that the lathing can be easily fastened Ato the supports"`without bolts, nails, screws, or rivets.

To enable others skilled in the art to make and use myinvention, I will proceed to describe the manner in which the fastening is done, reference being had to the accompanying drawing.

The studs or supports, and also the lathing, may be of any suitable material, thickness, width, and of such shapes as will best adapttbem to the purpose of' supporting the plaster-coat ref quired for the various walls used in buildings,

marked a a a, of such suitable depth and width asr will receive the edges of the laths. A section of such lath in position, colored red, is shown at B b. These slits are cut at an angle with the edge, varying, more orless, from a perpendicular line to such edge, and are also arranged in pairs, each pair of slits inclining either toward or from each other, the two slits composing each pair being used to fasten one lath, such fastening or locking of' the lath to the support being accomplished by forcing the two edges of the lath into the two slits, such operation causing the edges of the lath to f'ollow the line ofthe slits, which has the effect of locking the lath to the support.

Fig. 2 D E F V R represent a mode of fastening wherein C is th ey stud or support, near the edge 0f which are punched theopenings a a, of such suitable distance apart as will agree with the laths required to be fastened. In the place of such open- Fig. 3: G H J represent a mode of fastening where G is the stud or support, the edge of which is cut into recesses a a or projections lc It, the sides of such recesses or projections being inclined to each other, thereby giving a dovetailed recess or projection. The sides of the lath being cut away, the body b ofthe same is placed within the recessor between the projections; then, by means of a suitable tool, the body b of the lath is riveted or forced out to completely fill the space, and is thereby fastened securely in position.

Fig. 4: K L M O represent a mode of fastening where thin sheet metal of any suitable form is used for the stud or support C. A part of the edge at a a, which comes between the laths, is

cut away, and the remainder is, with a suitable.

tool, divided into two or more parts or tongues,

g g e e. These divisions are spaced off to suit the i lathing requiredto be supported. Part of these tongues or divisions, markedg g, are bent at right angles tothe body of the support; the lothers, marked e e, are left standing, as at 0. The laths used with this combinationV are provided with suitable slits cut through the body, of such a length as will correspond with the width of the tongues e e on the edge of the supports, and which have not been bent over. In the practical use of this combination, the/supports being in position, the lathsy are placed against the edges so that the tongues e e pass through the slits while the body rests against the tongues g g, an then they are fastened or locked to the support by bending or riveting the tongues e e down upon the body ofthe lath.

Fig. 5: I It S T represent a mode of fastening where thin sheet metal is used for the support C, the whole of the edge of such support being bent over at an angle to the body, forming a iiahge, against which the laths are placed. Through the body of the laths are punched suitable openings f f, at such proper intervals that the material left may be cut away so that the tongued part ofthe e lath may pass into suchV spaces, thereby adding to the security. Instead of the above-described mode, the same result may be obtained by bending portions e e of the flanged edge of the supports, as shown at T, out through the openings ffin the lath and forcing the same down upon the bodyr of the lath, thereby securely fastening the two together. t I wish it understood that I do not claim as new or original underthis application any ofthe forms of supports or laths, as shown and described; but- What I do claim as my invention, and Wish to secure by Letters Patent, is 1. Fastening sheet-metal laths to the supports prepared to receive them by forcing the edges of such laths into slits in the edges of such supports,

when such slits are cut at an angle to the edge of such supports, either more or less than at a right angle by the mere grasping force of such supports upon the laths, and of 'the laths upon the supports, without the aid of bolts, nails, rivets, or of beating out either laths or supports, substantially as described and shown.

2.V Attaching sheet metal laths to the supports provided for the same, by bending tongues formed from the body of the laths into openings or lgrooves provided in the supports to receive them, as shown in Fig. 2 of the drawing, and as above described.

3. Fastening metallic lathing to the supports prepared to receive them by beating out portions ofthe metal forming such laths into recesses, or between projections formed on the surfaces of such supports, as described.

4. Passing the tongues 0r projections formed on the edges of metallic supports for laths through slits provided in the laths; then riveting or bending these tongues or projections over upon the body of such lath, substantially as set forth.

5. Locking a metallic lath to the support prof vided forthe same by bending portions of the body of such lath back, over the edgeof such support, or by bending portions of the edge of such support down upon the body of such lath, as described, and as shown in'Fig. 5 of the drawing.
