PARTITION-WALL CONSTRUCTION.

Specification of Letters Patent.

Patented Sept. 19, 1905.

Application filed November 29, 1904. Serial No. 234,711.

To all whom it may concern:

Be it known that I, FREDERICK L. KANE, of the city, county, and State of New York, have invented a new and Improved Partition-Wall Construction, of which the following is afull, clear, and exact description.

My invention relates to improvements in the construction of partition-walls, such as are used to separate one room of a building from another; and the object of my invention is to produce a cheap and simple construction which will be practically fireproof, which will in any event be an excellent fire-retardant, and which can be easily put up so as to make a nice, even, plumb, and smooth partitionwall. My invention relates especially to improvements in the studding of such a partition, and my improved studding takes the place of the ordinary wooden studding and is made so that it will not warp, will hold anail well, will be fireproof, and will be molded so that it will afiord a fiat solid support perfectly plumb and true for the other portions of the partition.

My improved studding is also intended to serve the ordinary purposes either with lath and plaster of the usual kind, with metal lath and plaster, or with special plaster board, which is used as a substitute for the old-fashioned lath and plaster.

With these ends in view my invention consists of certain features of construction and combinations of parts, which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective View of a partially-constructed partition-wall, showing my improvements. Fig. 2 is a cross section through a piece of studding which forms a part of the partition. Fig. 3 is a view similar to Fig. 2, but illustrating means for holding the wooden portions of the studding in position during the molding process. Fig. 3 is a cross-section-of the studding, showing a means of bracing. Fig. 4 is a sectional plan of a series of studs with ametal trusswork applied thereto; and Fig. 5 is a broken side elevation of the construction shown in Fig. 4, the two views showing merely the skeleton work of the studding and the trusses or braces.

. My invention comprises, in part and essentially, the studding 10, which is of the usual rectangular shape, but which can be made of other shapes,i:t' necessary. Each piece of studding is provided with parallel longitudinal wooden slats 11, which are held in a mold while the body portion 13 is placed around them, and to the end that the slats may not twist, warp, or be displaced during the molding process a nail 12 or equivalent spacing means is driven through them and arranged to extend entirely across the mold. The nails serve to strengthen the studding, and obviously other means can be used for strengthening purposes. For instance, the strips 11 can be connected by coarse wiremesh 12, as shown in Fig. 3, or any equivalentconnecting means can be used which serves the purpose of spacing the strips and of strengthening the studding. Such a fastening as the nail can be put at intervals, say, of two or three feet, and the material 13, forming the body of the studding, is then poured into the mold, so as v to embed the slats 11 on all sides. This material can be any of the usual fireproofing compositions, such as hydraulic cement or lime or concrete, and I preferably use a mixture of plaster-of-paris and some fibrous materialsuch as sawdust, cinders, excelsior, or the like--sufiicient water being also used to make the substance of the right consistency. Sand, gravel, or clay may be used; but the above materials are preferred to save weight and admit of nailing. When this is poured into the mold, it embeds the slats, as stated, and forms an even, plumb, flat-surfaced, and strong piece of studding. I am aware that heretofore pillars or posts of wood have been embedded in fireproofing compounds; but by having the parallel slats spaced apart, as shown, several objects are attainedfirst, much less Wood is necessary; second, the embedding material. fitting between the slats and also around them forms a composite structure which is very stiif, and, lastly and most important, the two slats being relatively near opposite sides of a piece of studding afford an -excellent hold for nails, which can be driven into the studding, as usual, and embed themselves in the wooden portions 11.

If desired, the studdingcan for certain purposes be braced by a suitable trusswork or braces, and in Figs. a and 5 I have showna good means of doing this. Here oppositelyarranged braces 14 are used, which are bent so that the ends can be fastened to the studding on one side of the partition, while the body portion will extend around the middle piece of studding and be fastened on the other side, and to this end the parts 15 and 16 are flattened, so as to fit the studding nicely.

The preferred form of' construction is shown in Fig. 1, in which plaster-board 16, which is used largely in making good fire-retarding partition-walls, is attached direct to the studding, and the coating of mortar is then spread on, as usual, over the plaster-board. This makes a nice essentially-fireproof partition which can be easily put up and which is sure to be regular and even and plumb in its construction. It will be understood, however,

that the st-udding can be placed as usual and that the ordinary lath and plaster, metal lath and plaster, or any usual finishing devices attached to the studding.

Having thus fully described my invention,
