'CORYDON T. PURDY, OF NEW YORK, N. Y.

PARTITION CONSTRUCTION.

SPECIFICATION forming part of Letters Patent No. (384,160, dated October 1 5, 1901.

Application filed September 10 1898. Serial No. 690,637- (No model.)

To all whom it may concern:

Be it known that I, CORYDON T. PURDY, a citizen of the United States, residing at New York, county of New York, State of New York, have invented a certain new and useful Improvement in Partition Construction; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to the construction of fireproof partitions in buildings; and it consists in the construction and combinations hereinafter described and claimed.

Its principal object is to provide a partition for cheaper buildings, in which present methods are unsatisfactory.

The ends which I have sought to accomplish are, first, greater economy in construction; second, less weight 5 third, ability to erect without employing masons or using mortar; fourth, greater cleanliness in erection, and, fifth, better fire protection.

Partitions must be thin and light in order to be cheap, as they necessarily must be in cheaper buildings, like apartment-houses and tenements. Openingsinsuchpartitions must also be framed with wood, and this makes them unreliable when exposed to fire. The wood burns out and to a greater or less extent the partition, made of thin and relatively small sized blocks of material, fallsapart, making a wreck of the partition when the material itself does not burn or even crumble because of the heat. The partition which I have devised is not open to this objection. The openings are framed with metal, which is a part of the design, and the idea of its construction involves the combining together of the parts so well that it will not go to pieces in any emergency. It is obvious that the lightening of the weight of the partition will in turn lessen the amount of metal required in the floors and that in this way the Whole structure is cheapened. The surface may also be made smoother and more regular in outline than in ordinary tile partitions, and on this account less plaster will be required to finish them, efiecting in this way still another saving of cost.

In the drawings, Figure 1 represents a builtup partition of slabs of incombustible material of the peculiar form designed by me and having a door-opening. Fig. 2 is a perpendicular cross-section of a part of such partition on the line 0200. Fig. 3 is a longitudinal cross-section showing the supporting-post and door-frame on line y y. Figs. 4E and 5 show the forms of slabs used, with recesses for the reception of the metal stiffening-bars.

Figs. 6 and 7 represent angles in the partition. Fig. 8 is a longitudinal sectional view of the partition, showing the mode of fastening the slabs of incombustible material together and inclosing the metal stiffeningbars. Fig. 9 is a longitudinal sectional View representing the juncture of one partition with another. Fig. 10 is a detail figure showing one way in which the metal fasteners may be made.

The shapes which I prefer to use must be molded of incombustible material having the essential form shown in Figs. 4 and 5 and as modified in Figs. 6 and 7. The essential elements of this slab consist in the fact that on one side it is plain, with right angles at the edges, and upon the other side, as at a a, it is channeled. The Width of these channels is not material. The raised edges, however, in the complete block of Fig. 4 are but half the width of the central ridge at (1 Fig. 5 shows a half-slab with one channel and with the edges a of the same width as the outer edges Ct C6 of the slab A of Fig. t.

In the construction of a partition the slabs are laid upon edge with their plain surfaces outward, the inner edges a of one slab touching the slab opposite on the middle of the central ridge a This is shown in the sectional view, Fig. 2. It is thus obvious that the slabs break joints perpendicularly, leav- I ing air-spaces B B between them. I employ a stiffening-bar fastened to the fioor and the ceiling to support this formof partition, and an ordinary channel-bar, a section of which is shown in various figures at O O, is suitable for the purpose. In order to permit the edges a, a and a to be brought together and inclose the stiffening-bars O,notches a are made in the raised edges and center ridges on the inner side of the slabs, into which the bars fit. After the slabs A A are in place, inclosing the stififening-bars, I secure them by through-fasteners D, a form of which is shown in Fig. 10. This consists of ordinary stiff wire looped in the center at d and then brought together and continued perpendicularly to the loop and bent out at the end after being put in place. I-Ioles are made in the partition and the fasteners are inserted through them. The two extremities of the Wire bent outward form a clasp, as is shown in Figs. 6, 7, 8, and 9. As many of these fasteners may be used as is desirable to properly secure the slabs in place. That these fasteners should be metal is an essential element of my invention, but their form is immaterial.

In Fig. 1 I have shown a door-opening at W, and in Fig. 3 a cross-section of such opening on line y y of Fig. 1, with a wooden doorpost W attached thereto, showing the man nor of connecting the door-frames. In this cross-section, A A represent the partitionblock, while 0 represents a metal stiffenerbar. This is set so that the blocks A A project slightly beyond at a.

I mains, nevertheless, intact.

The door-frame W may be shaped as shown in the drawings in cross-section, with a projecting ridge 7 of the same width as the width of the stiffening-bar and secured to it by a sufficient number of screws S. The fastener D may go through the blocks A A and the door-frame, as shown by dotted lines. The wider portion of the door-frame atffis preferably beveled, although the form is immaterial. The entire thickness of the door-frame W is supposed to be that of the partition itself after the plaster P P is added to the blocks. Outside of the door-frame W and the plaster P P may be placed the j amb and casings. (Not shown.) In this construction if the wood burns away in a fire the parts of the partition are not thereby separated and the construction re- Other details of construction for openings may also be employed to the same end.

Figs. 6 and 7 are sectional views of angles in the partitions, Fig. 6 being that of a curved angle and Fig. 7 of a square angle. In these cases the slabs of incombustible material of which the partition is built would be molded in a curved or angular form, as required, as shown at H and J in Fig. 6 and at K and L in Fig. 7. The mode of arranging and combining them with reference to the channelbars 0 O and the fasteners D is suflioiently obvious from the previous description and from the drawings.

In Fig. 9 I have shown one partition meeting another in which curved slabs are used. In this case the form shown in Fig. 6 at H must be used. In this case also the arrangement of the channel-bars and fasteners is obvious and needs no description. In Fig. 9

the outside adjacent to the cross-partition is faced with a plain slab like the ordinary blocks forming the body of the partition. The arrangement shown in Fig. 9 is not the only form-in which one partition may meet another. It is obvious that the slab K (shown in Fig. '7) might be used in a similar manner in place of the slab marked H.

In a partition constructed in accordance with this invention no two joints preferably come together. The hollows B B, heretofore referred to, form air-spaces, and this makes the partition nod-conductive of sound and heat.

The construction of the partition is very simple, and when erected the integrity of the structure will not depend at all upon the wood construction which may be put into doorways or other openings.

What I claim is' 1. A partition formed by a combination of channeled slabs of incombustible material, and metal stiffening-bars fastened to the floor at the bottom and to the ceiling at the top, the channeled slabs forming a double wallinclosing the stiffening-bars, and so formed andplaced that they form hollow spaces extending across the line of the stiffening-bars, substantially as described.

2. In partition construction, the combination of slabs of incombustible material fastened to each other and held in place with pieces of metal, adapted to be inserted transversely through the partition and into a holding position, substantially as described.

3. A partition formed by a combination of slabs of incombustible material, metal stiifening-bars, and small pieces of metal, the slabs of incombustible material crossing the metal bars and inclosing them, and the small pieces of metal binding the slabs of incombustible material together, substantially as described.

4. In afireproof partition, the combination of angle-blocks of fireproofing material turning the corners and adapted to break joint, a post on either side of the corner passing through the space between the tiers of blocks from top to bottom, the means for securing the blocks in place inclosing the post, substantially as described. 4

5. A partition formed by the combinationof channel-slabs of incombustible material, perpendicular metal stiEening-bars located in grooves fashioned in the slabs for their ad mission and flexible metallic horizontal ties for holding the slabs in position inclosing the channel-bars, substantially as described.

6. A partition formed by a double wall of channel-slabs of incombustible material, so formed and placed that the joints on the edges shall alternate, and flexible metal transverse fasteners for holding the same in place, substantially as described.

7. In partition construction, the combination of corner-slabs of incombustible material constructed substantially as described, joint or opening on the immediate line of the metal stiiifening-bars adjacent to each side of corner is obviated, and means for securing the corner whereby a vertical joint at the corthe slabs in position, substantially as dener is obviated, and means for securing the scribed.
