Inf/effici- UNITED STn'rnsy PATENT FERDINAND H. MELA, OF NEW YORK, N. Y.

FIREPROOF PARTITION.

SPECIFICATION forming part of Letters Patent No. 515,496, dated February Q7, 1894.

Application filed June 21, 1893. Serial No. 478,336. (No model.)

To @ZZ whom 2325 may con/cern:

Beit known that I, FERDINAND ll. MELA, builder, residing in the city and county of New York, in the State of New York,have invented a certain new and useful Improvement in Fireproof Partitions, of which the following is a specification.

The present invention is an improvement based on that set forth in a patent to me dated May 16, 1893, No. 497,383.

I have devised means to facilitate the placing of the slabs of terra-cotta lumber or analogous hre-proof material and an improvement which facilitates the manufacture and the application of the horizontal tie-bars.

The following is a description of what I consider the best means ot carrying out the invention.

The accompanying drawings form a part-ofy this specification.

Figure l is a horizontal section on the line l-l in Fig. 2. Fig. 2 is an elevation showing the upper and lower parts of a partition partly in vertical section, with avertical section of portions of the adjacent wall floor and ceiling. Fig. 3 is a vertical section of a portion on the line 3-3 in Fig. 2. Fig. a is an elevation of a portion of one of the metallic uprights. Fig. 5 is a horizontal section thereof on the line 5-5, and Fig. 6 is a horizontal section on the line 6 6. Fig. 7 is a side view of a portion of a tie-rod. It shows a modification.

Similar letters of reference indicate corresponding parts in all the iigures where they appear.

A is the floor below, and A A', shown in dotted lines in Fig. 2, are metallic knees secured thereon.

B is the ceiling, and B metallic knees secured thereto. Y

C is one of the main walls of the building, and sufficient-ly recessed at certain points to admit the ends of Vthe tie-rods, to be presently described.

D is one of a seriesA of metallic uprights, which it will be understood are set at proper distances apart in the line of the partition. D are iianges on these uprighte. A portion of one of these flanges in each upright near the ceiling, is cut out` as indicated at d', to allow the slabs of fire-proof material to be conveniently inserted, as will presently appear. I punch or otherwise produce holes d at the required levels in the bodies of these uprights.

E E are the horizontal tie-rods. `Each is formed of a length only a little greater than the distance between two uprights, and each end-portion E is bent at aright angle. The holes d are sufciently wide to allow two of these rods E to lie therein side-by-side. I apply them thus, one reaching to the right and one to the left.

H are rectangular slabs of porous brick, terra cotta or analogous tire-proof material, adapted to afford the necessary mechanical strength and tire-proof qualities, with lightness and reasonable cost. I prefer what is sometimes called terracotta lumber. The holes cl and the rods E are arranged with reference to the height of these blocks so thata tie-rod shall extend horizontally inthe space 1between each slab and the corresponding slab lying nextabove.

Each slab is narrowed a little at each end so that it can move up and down between the flanges D of the uprights. After theuprights are erected and strongly confined to the ceiling and licor, I apply the several slabs lvl and rods E E in the proper succession with sufficient mortar to fill the joints; and when the whole is completed, cover both faces iirst with rough-coat and finally with hard-finish, and the walls are complete. All the slabs, including those that go to the bottom and lie upon the Vfloor, are introduced by holding them upright on edge, lifting them to the level of the apertures ci', and then first inserting one end between the complete anges D D of one upright, the one on the right in the figures, and after this end is approximately in position the other end is moved bodily inward through the aperture' d. New the slab is in place except that it is too high, and it is next lowered, guided by the flanges D D', at each end until it rests on the floor. Having thus inserted the iirst slab in the space between each upright and the next, a set of the tie-rods E E are next inserted and lowered alittle so that their ends will engage reliably. The depth of the holes d must be equal to the extent of the bent portion E', and the width equal to the diameter ot two of the rods. The rods lie in the holes side by side, one serving to support IOO the upright against strains impelling the latter to the right, and the other holding it against strains impelling it to the left. After the next tier of slabs has been laid in position, the next set-of tie-rods is applied, and so on to the top. The last tier of slabs is held reliably by the flanges at one end, and the other end requires to be fastened to the single flange which is there presented. I eltect this by means of a bolt F tapped through the standing flange. I insert it through a hole 7?. provided in` the slab, and provide it with a Washer F', aording a reliable bearing on the slab. All the joints are liberally iilled with or pointed with mortar applied during the laying, or immediately after.

Modifications may be made Without departing from the principle or sacrilicngfthe advantages of the invention. I can by giving a slightly greater excess of length, to the tierods and bending theml in the heated state by hand or by machinery', to thek form showny in! Fig. 7 make it serve strut-Wise as Well as tension-wise and thus brace the uprights in; which itl is engaged against displacement either to the right or left.

To avoid the necessity of manufacturing speci-al slabs tol receive the bolts F, I can make a hole adapted to receive such bolt in each slab, but only the upper slab in each tier requires such. Instead of a hole a simple notch may serve. NVhen occasion requires that a slabv shall be used for the top which hasy not been perforated, a notch can be roughly made' by breaking'. I can break a corner to allow for the knee A. I have shown such a provision for the uppermost in Fig.- 2, but it may be preferable to make each slab With two corners properly shaped to thus apply. The die for punching the hole d may have 4o rounded corners, and correspondingly produce holes only approximately rectangular.

Parts of the invention can be used Without the hole. I can-.use the apertures d and insert the slabs in the manner described at the top and lower them into place using other 'forms of tie-rods, as for example, that set troduction, arranged to serve as herein specitied.

2. TheIire-proofpartitiondescribed having 6o the anged uprights D with holes d to receive tie-rods and cut-out spaces d to facilitatethe introduction of Y ireproof slabs H, in combination with such slabs and with tie-rods E having ends E adapted to engage andsupport the uprigh-ts, and with' means as the bolts F and Washers F for hold-ingv the upper slabs, all arranged for joint operation substantially as herein specilied.

In testimony that; I claim the invention 7o above set forth I affix my signature inA presence of two Witnesses.

FERDINAND I-I. MELA..
