Application filed December 19, 1907; Serial No.4( )7,219.

To all whom it may concern: j

Be it known that I, JOHN W. WHITE, a citizen of United States, residing at Spokane, in the county of Spokane and State of Washington, have invented certain new and useful Improvements in Concrete Blocks, of which the following is a specification.

This inventionrelates to concrete blocks, and more particularly to the means eniployed for strengthening the webs between the usual air spaces.

Other objects and advantages will be hereinafter referred .to and particularly pointed out in the claims In the drawing-Figure 1 is a horizontal section of my improved block. Fig. 2 is a transverse section on the line 2-2 of Fig. 1. Fig. 3 is a horizontal section of a slightly modified form of the invention. Fig. 4 .isa transverse section on the line 4-4, -Fig. 3..

The numeral 1, indicates a blockfprovided at one end with a reducedlextension 2, to overlap la similarv extension on an' adjacent block. 'The body of the block is formed with a centrally disposedflue 3, and in the four walls and adjacent this flue are minor iiues' or spaces 4. The flues are formed for the purpose of allowing the usual air sp ace in wall construction. of. the flue 4, are webs 5, to strengthen the structure. The flues 4, form what I j shall hereinafter term "inner walls 6, and outer walls 7, said walls being connected by the Webs 5. v

Reinforcing .elements 8,' formed of wire, are embedded approximately near the top and bottom of the inner wall 6, and extend completelyv around the same. The reinforcing elements have twisted corners 8", and extend diagonally outwardly, and. are enibedded in the webs 5. The twists ofthe wire are loose toperinit the cement to pass between them to assist in strengthening the structure, as clearly shown in Fig. 1. In substantially the same horizontal plane as the reinforcing elements 8, and embedded in the outer wall 7, are reinforcing elements 9, having theirends twisted to form eyes 10, through which Vthe concrete may pass. The reinforcing' elements 9, project laterally, and are embedded in the extension 2, where the ends are twisted to form eyes 11. Extending between the ends 12, of the portions 13, of the reinforcing elements 9, -are connecting reinforcing elements 14. These elements 14,

to the face of the extension 2, is a lobp v16,

Between the adjacent ends pass through a web 14a, formed in the extension adjacent flues 15. Connected to the upper end piece 12, and extending outward y designed to overlap'the upper face of an adjacent blocl when the blocks are assembled` in wall construction.

In 'Figs 3 and 4, I have shown a slightly different form of the invention, the same consisting of a block 17',- formed with parallely flues 18, with an intermediate web 19. y Reinforcing elements 20, are embedded inthe block near the upper and lowerfaces of -the saine, and have their ends twisted to form. eyes '21. Connected to one end of the rei'n forcing element 20, is a wire 22which extends to the outside of the end of the block and performs the same function as the wire A reinforcing element 19", isernbedded` in the web 19, and extends to the outside to secure slats for lathing purposes.

A block such as described .may be made comparatively light, and possesses substan- V tial strength by reason of the particular location and vconstruction of the reinforcing element. The twistingof the. Wiresperrnits Q5." the vpassage of the concrete and insures of the same eing rigidly embedded in the mass and effectually strengthens the construction.

1., A concrete block formed with fines and diagonal webs between the iiues to connectthe corners of the walls forming the iiues, re- Y inforcing elements embedded in the block, said reinforcing elements having,diagonallyy arranged twisted portions and formed with eyes the twisted portions extending into and are embeddedin the diagonal webs and the -eyes extending beyond the webs and ein? bedded in the block., and reinforcing elements embedded in the block` outside the plane of the twisted reinforcing elements.

2. A concrete block formed with flues in the body portion thereof, diagonal webs be` tween the' flues to connect the corners of the walls forming vthe fines, the block having a reduced extension formed with iiues, a reinforcing element embedded in the body portion and having. twisted portions to form eyes the twisted portions extending into and are embedded in .the diagonal webs and the eyes extending beyond, the webs and embedded in the block, and other reinforcing elements einbedded'in the body portion outm 'side the plane of the first mentioned reiniio portion formed with fines, and a reduced extension formed 'with iiues, reinforcing ele` inents formed of Wire, and provided with a projecting portion, the body of said reinforcring element being embedded in the body of fthe block" and the projecting portion being iembedded in the extension oi' the block, the reinforcing element having twistedA portions form eyes through which the concrete passes.,

\4A concrete block comprising a body portion formed 'with iiues, reinforcing elements embedded in the body portion outside the piante of the iiues and formed with eyes through which the concrete passes.

5. A Concrete block comprising a body portion formed with fines, and e reduced extension fornied with flues, reinforcing elements embedded in the' body portion and the extension, and a loop extending from the reinforcing eienient to the outside of the extension near the top thereof.

In testimony whereof I affix niy signature in presence of two Witnesses.-

JOHN W. WHITE.
