To all whom it myconcern:

Be it known that I, ISAAC-V. HOLMES, of New York, in the county of New York,- and in the State of New York, have invented a new and 'Improved Metallic Stud for Fire-Proof Walls; and I do hereby declare that the fol-k serews,or rivets', 'and may, when so fastened to them, materially add to their stii'ness' and strength, and thus secure a saving in the ma- 4terial of which they-are constructed.

V r Io enable others skilled in the art to make and use .my invention, I will proceed to describe its construction and operation.

I construct the studs or supports of iron or other'suitable material, of such thickness and width and of such shapes as will best adapt them to the purpose of supporting the lath required for the various plaster walls used in building-such as theveitical surfaces of partitions and side walls; curved surfaces, such as cornices, moldings, anddomes; horizontal or angled surfaces, such as plain or paneled ceilings-imany given case the thin or recessed edge or surface being presented to the lath or plaster, thus aording stiffnessfand strength to resist pressure against the face of the wall when made. Y

lFigures 1, 2, and 3. respectively represent side views of studs for vertical walls with different forms or proportions of recesses for receiving the laths. In the use of 'my invention the variations in the form, shape, or proportion of the recess is made to suit the peculiar shape or form of lath to be used; and I do not confine my improvement of a recess or projections on the face of av stud to hold a lath in position to any particular form of lath. Fig.

4 is a front elevation, showing the laths'and stud combined. Fig. 5 is a perspective view of the studs and laths in position. y The general form of such laths as these studs invention consists in con! are intended to be used with is shown by the ing in what form the sheet metalis bent in con.- structing them, while afrontview of their faces when in position in the studs is shown in Fig. 4 by the letters e e e. recesses for the laths cut away from it of the width of the laths and of a little greater depth than Athe thickness of the metal of which they are formed, and these recesses are made just as far apart as it is desired to have the lat-hs on the stud, -and a projection of the material of the stud is left between adjacent recesses. The ends of the recesses may be cut under or atan angle, so that thecorners'may overhang the lath, ifnecessary; also, the recesses may be so proportioned or spaced ofi' that the projections may pass through a mort-isc or opening punched or out in the ,'lath. The bent-back edges of the lath, of a width equal to the thick; ness of the studs, -are cut away and removed, vso that the back of the body of the lath will fit up against `the edge of the stud in the recess when the back of the lath is placed iiat upon the recess, andthen by the use ofany suitable calking-tool the metalofthe projectionf may adjacent laths, as' at g g, and such' edges or corners are thus madevfast tothe stud.

In the case of using a lath with an opening in the body of Vthe same to receive the projection, then the metal forming the projection close up the opening, and by that means secure the lath in position. Of course when these studs are placed in position to support tthe wall-surfaces, these projections or recesses should bein line.

In Fig. 2,-B represents a stud-with the recesses of a dierent form or proportion. Here the variation is caused by making the recess C deeper and the proj ecti onf longer. The seating ofthe lath is in a' different manner, as no part of the lath is cut away; but it is placed in the recess'and forced with .its edges against the back of the recess until these edges, which were formed at right angles to the face of the lath, are bent or curved into a direction par allelto the iace, as shown by the red lines in B', and bringugthe face' of the lath a little red lines and letters ve e e in Figs. .1', 2, and '3,1 where end views are presented of them, showrllhe stud A, Fig. 1, 'has be beaten ontand riveted upon the corners of would be riveted down or expanded, so as to,
