SEC'TiO NAL WALL OR CEILING.

EPECIFICATION forming part of Letters Patent No. 739,646, dated September 22, 1903.

Application filed May 8,1903. Serial No. 156,208. on an.) 7

To all whom it may concern: r

Be it known that I, JOHN ALEXANDER CAR- TER, a citizen of the Dominion of Canada,and a a resident of Summit, in the county of Union and State of New Jersey, have made a certain new and useful Invention in Sectional Walls or Ceilings; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification. v

Figure 1 is a perspective View illustrating the application of the invention to one form of ceiling having wooden joists. Fig. 2 is a side view illustrating the application of the invention toa fireproof ceiling. Fig. 3 is a perspective view of one of my plaster sections. Figs.

Land 5 are detail cross-sections on the lines 44' and 5 5, Fig. 3. Fig. 6 is a detail perspective view of metal hanger C. Fig. 7 is a sectional detail view to illustrate how hanger G is secured in position in the plaster section.

This invention has relation to sectional walls and ceilings, and has for its object the provision of finished plaster sections whichcan be quickly and securely applied or put together in place in an exactly even manner by unskilled workmen'in'such way that they will mutually hold or brace each other against warping or displacement.

With this objectjn view the invention consists in the novel construction and combinations of parts, all as hereinafter described, and pointed out in the appended claims.

Referring to the accompanying drawings, the letter A designates one of my plaster sections, usually of oblong rectangular form and having a body or framework of burlap B, upon both sides of which is built the plaster, rough finished upon the inside of the section and polished in a finished manner upon the one side thereof, this being accomplished by casting upon a polished surface, such as glass. This plaster section is rabbeted at a upon the inside thereof upon two sides of its perimeter and rabbeted at a upon the outside upon the other two sides of its perimeter, lockin g metal tongues or projections i) being let into the plaster while it is in a soft state at the edges ;or margins upon.'the inside of. the sections and extending over and beyond the rabbet of all four sides. The tongues or projections 19 are of double-angle or Z fornnwith long bases, which lie upon the burlap body and are suitably covered in with the plaster, the long bases of opposite tongues being connected or integral transversely of the section. 7

In use the rabbet upon the inside edges of one section will overlap or engage the rabbet "of the outside edges of the adjoining section, and vice versa, the bracing metal tongues b in each case spanning the joint of said edges and extending over and beyond the rabbet, whereby there can be no lifting or depression of one section with reference to its neighbor, the mutallyabutting edges at the same time preventing any lateral or edgewise displacement of the sections. The tongues I) rest upon the rear or inner marginal surface of the plaster section and project beyond its rabbeted edges.

In securing the sections in place upon the ceiling incases where wooden joists are in use the perforated metal hangers C, Fig, 1, are letintothe soft plaster, such hangers having T-form heads 0, lying upon the burlap framework, and having a reinforcing-strip of burlap c. placed thereover and suitably covered in with plaster. These T-form hangers are preferably formed or a single piece of sheet metal doubled transversely and having one end split or opened at the doubling-line, the two separated halves at this endbeing bent-in opposite directions at right angles to the main portion of the piece. Nails are driven through the perforations of the hangers into the joists.

In securing the sections in place upon fireproof ceilings hangers D, Fig. 2, are employed of the same general shape as tongues 1), except at one end or short side of the section, where the hangerrbases are reversely beut, as at d, these hangers having, however, their head portions projecting beyond the plaster to leave a space or interval therebetween in which is received the furring of the ceiling by lateral or edgewise movement of the section being handled.

Having thus described my invention, what I claim as new, and desire to secure byLetters Patent, is-- 1. A plaster section for sectional walls, hav-' ing rabbeted edges and edge-locking tongues resting upon the rear or inner marginal surface of said section, and projecting beyond said edges, substantially as specified.

2. A sectional wall-facing consisting of interfitting plaster sections, each of which has rabbeted edges, and edge-locking tongues spanning the joints of said edges, substantially as specified.

, 3. Aplaster cast section for sectional Walls, having an inside fiber layer and outside plaster layers, one of which has a finished surface, substantially as specified.

4. Aplaster section for sectional walls, having an inside fiber layer and outside plaster seems to said fiber layer, substantially as specified.

In testimony whereof I afiix my signature in presence of two witnesses.

J. A. CARTER.
