FIREPROOF CONSTRUCTION.

SPECIFICATION Jorming' part of Letters Patent No. 663,204, dated December 4, 1900.

Application led May 28, 1900.

,. adapted to engage oppositely-arranged keys on abutting arch-blocks.

It further consists in forming arch-blocks so that t-he same will break joint.

It further consists in providing` means for locking the arch-blocks together.

Figure 1 represents a perspective view of a portion of a iireproof construction embodying my invention. Figs. 2 and 3 represent perspective views of the arch-blocks ernployed. Fig. l represents a side elevation showing a dierent form of arch-block employed.

Similarletters of reference indicateV corresponding parts in the drawings.

Referring to the drawings,A designates Van arch-block which is formed with a curved lower edge B and provided with the lugs or keys C and D, projectingfromV the abutting edge of said arch-block, the lug D being so arranged as to provide a shoulder E, upon which is adapted to rest a key of an abutting arch-block, the lug C being adapted to rest upon a projecting key similar to the key D of the abut-ting arch-block, it being seen that said keys are so arranged that the abutting arch-blocks break joint about midway, allowing approximately the half of each archblock to project on either side to receive the next abutting arch-block. Each arch-block is provided with the grooves F for the reception of the foot G of the I-beain Hiand is provided with a projection J, oneset of archblocks being provided with tongues K on said projection J and the others with grooves L in said projection J for the reception of the said tongues K of the next arch-block, it being noticed that said tongues K and grooves L are beneath the beam H when in position.`

Serial No. 18,195. (No model.)

One side of each arch-block is provided with a lug M, the opposite side of each arch-block having an opening N therein adapted to receive the said lug on the next side abutting arch-block.

Embedded in the arch-block is a wire mesh P, having the ends Q of one set of wires projecting from the abutting ends of the arch-Y block and being flexible, 'and the ends R extending from the projection J and being flexible, it being seen that when the arch-blocks are in position the ends Q of the wires of abutting arch-blocks are twisted together, while the ends Rot the wires are twisted, as will best be seen at S, so that each series of arch-blocks are locked together at the abutting ends and at the lower ends to the next series of arch-blocks.

i T designates a slot at the rear of the archblocks to permit concrete to pass thereinto and ll any grooves that may occur between l the arch-blocks and the beams.

Each archblock is provided with hooks or eyes U, to which are secured wires V, which are also secured to the I fbeams, forming a support or brace for the abutting ends.

The voperation will be readily seen. The arch-blocks are placed so that the upper extending lug rests upon the shoulder formed by the lower extending lug of the end abut.- ting arch-blocks and so that the arch-blocks break joint, the projections entering the openings N in the next adjacent arch-blocks, the tongues K entering the grooves L beneath the beam, while the ends Q and R of the wire mesh are twisted and locked and the wires V connected with the eyes U and the beam H, thus securely fastening the various part-s together and preventing sagging or breaking apart.

Vhile I have shown the preferred form of arch-block employed, I do not desire to be limited in every instance to the exact construction as herein shown and described, for in Figs. l, 2, and 3 I have shown an archblock with a grooved bottom, while in Fig. 4: I have shown a dat base, making a flat ceiling.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, ise 1. In a reproof construction, arch-blocks,

a key extending from the abutting edge thereof at substantially the upper edge and adapted to rest upon al key on the next abutting block and a key extending over substantially 5 the lower edge upon which another key ofl another abutting arch is adapted to rest. Y

2. In a fireproof construction,an arch-block, a key extending from the abutting face thereof near the upper edge and adapted to rest 1o upon a key on an abutting arch-block, a key extending near the lower edge thereof, upon which a key of another abutting arch-block is adapted to rest, and said arch-blocks being so arranged as to break joint with the abutting arch-block.

3. In a reproof construction,an arch-block having a lug or key extending from substantially the upper edge of the abutting face thereof and a lug or key extending fromA subzo stantially the lower edge of the abutting face,

a groove adapted to receive the foot of an VI-beam, a projection on said arch-block which lis provided with'a groove adapted to receive a tongue on the nextarch-block.

4. In a fireproof construction, an arch-block having a key extending from the abutting face thereof at substantially the upper portion and a key extending from said abutting face at substantially the lower portion there- 3o of, a lng projecting from one side thereof and an opening in the other side.

5. In a reproof construction, arch-blocks provided with oppositely extending lugs, means for locking said arch-blocks with respect to the next abutting arch-block, and means embedded in each of the said archblocks for connecting one with the other.

6. In a fireproof construction, an I-beam, an arch-block, a key extending from the abutting face thereof, and a key from the abutting face below the first-mentioned key at one side thereof, and means connected at or near the abutting edge of said arch-block with said I-beam for supporting said arch-block.

7. In a tireproof construction, arch-blocks so arranged as to break'joint, and a wire mesh embedded in said arch-blocks, so arranged as to have projecting ends which can be secu red to the next abutting arch-blocks.

8. In a ireproof construction, arch-blocks .-suitably constructed, each having one end adapted to rest upon the foot of an I-beam,

keys on the abutting edges of said arch-blocks,

and tie rods or wires connected with the forward ends of said arch-blocks and to said I-beam.

9. In a freproof construction, an arch-block having keys extending at varying heights from the abutting edge thereof and out of e tical alinement and engaging with oppositely-extending keys on two abutting archblocks.

lO. In a ireproof construction, a beam, an arch-block supported thereby', and means projectin g from said arch-block which is adapted to enter a groove in the next abutting archblock below said beam.

11. In a fireproof construction, beams, archblocks-and means connected at or near the abutting edges of said arch-blocks and with said beams for supporting said arch-blocks.

12. In a ireproof construction., arch-blocks, means on the abutting face thereof whereby a portion of an arch-block rests upon a portion of the adjacent arch-block and means lout of vertical alinement with the first-mention-ed means and on the same abutting face whereby a portion of said first-mentioned arch-block serves as a support for an adjacent arch-block.

13. In a fireproof construction, an archblock having a key extending therefrom with its abutting face pointed downwardly, and a second key extending from said block out of vertical alinement with said rst-mentioned key and at a different height and having its abutting face pointed upwardly. i

I4. In a Ireproof construction, an archblock having means on its abutting face for engagement with the next abutting archan I-beam, a projection on said arch-block which is provided with a groove adapted to receive a tongue of the next arch-block.

l5. In a firep-roof construction, an archblock having means on its abutting face for engagement with the next abutting arch, a groove adapted to receive the foot of an I-beam, a projection on said arch-block provided with a tongue and adapted to enter a groove in the next arch-block.

16. In aA iireproof construction, an archblock having a key extending from the abutting face thereof at substantially the upper portion and a key extending therefrom at substantially the lower portion, a lug projecting from one side thereof, an opening in the other side and said arch-block being so arranged as to break joint with the abutting arch-blocks when in position.

17. In a iireproof construction,an I-beam, arch blocks, means on the abutting faces thereof for engagement with the next archblocks, and means connected at or near the abutting edges of said arch-blocks and with said I-beams for supporting said arch-blocks.
