FORM non MAKING HOLLOW BRICKS, TILES, nn THE"LIKE..

Application filed January 29. 1927. seriaino. 164,602;

The present invention relates to the metal forms which are used with wet mixed concretebrick oritile. 3

' The principal object ofithe invention is to improve upon the cores which are bolted as usual onto flattened bars for the purpose of holding the cores in place so as to make a 7 practical integral structure.

. The improved core is designed to make a light weightpartition or non-load bearing brick or concrete tile.

'The ordinary. coreused in the making of tile by wet mixed'process is straight sided 'without any holes or openings which makes a hollow brick or file that has a web or wall of the same thickness at the top and bottom. The, purpose of the present ini- I proved core is-to make aside wall and web ofa' differentrthickness at the top and bottom. "Another important feature inthe core is that it is provided with inletting air openings to eliminate suction; the core being designed tohave two wall thicknesses with an air chamber and air ports.

in through ports made at the 'top of the core and the top of the air space in the side wall form The inletting' of the air through the ports with a core designed as hereinafter described, eliminates suction to a minimum and makes it possible to lift the entire form with cores attached, leaving the tilein place and intact.

-Another very important object of the in vention lies in the provision of a form of 7 this nature which is'fcomparatively inexpensive to manufacture, is strong and durable,

' i is thoroughly efficient and reliable in use and otherwise well adapted to the purpose for which it is designed. I

With the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as .will be hereinafter more fully described and claimed.

In the drawings: 1 Figure 1 is a top plan view of the form embodying the features of my invention, Fig. 2 is a longitudinal section taken therethrough substantially on the line 22 of Fig. '1, i r Fig. 8 is a fragmentary transverse section ure 1,

The air is let taken substantiallyonthe line 3 3 ofFig- Fig. 4::isa detail of the cores, 7 r Fig. 5 is a detail perspective'view of one of thebricks or tilesformed inthe mold of form.

Referring to the will be seen that the numerals 5 denote-thetwo end cross pieces and the numerals ti denote two side or. longitudinal features. Transverse partitions 7 and longitudinal partitions 8 are provided in the usual manner-.- -Supporting bars 10 are fixed to the end piecesc5 in the usual manner'to extend longitudinally-of .the form and longitudinally-across thecompartments formed by the partitions? and'8.l The structure thus far described is of the common well known form and has been illustrated merely by way of. example to clearly demonstrate the utility of my improved core. V 1 T I Two of my improved cores are attached to the bars 10 in each compartment formed by thepartitions7 and 8;, These cores are mountedin spaced relation as is the custom. I at present-1 Ac detailed description of. one of the c'ores will suffice for all since they are all of identically the same construction. Each core comprises a top plate 11 of rectangular formation having a, central transperspective view ofone drawings in detail, a I

verse groove 12 formed in the upper sur- I face thereof for receiving the bar 10 to which it-is bolted. Walls 14: and 14: depend from the edges of the topplate 11 to form V a rectangular box-like construction. Portions 15 of the walls 1d project inwardly and upwardly and terminate in downwardly directed extensions 16 which are at right angles to the walls 14:. One side extension 16, it is to benoted, is disposed farther inwardly than the other,'see Fig. 3. The juncture of side walls 14 with the plate 11 are provided with apertures or openings 18.

The junctures of the extension 16 with the inwardly directed-portions 15 are provided with apertures or openings 19.

These cores will form the hollow bricks or tiles 20 shown in detail in Figure 5 so that the upper portions'of a pair of the .oppositewalls will be thinner than the lower portions thereof. It will be noted thatwhen the concrete is poured into the forms that c it will seek its ,own level up underneath the inwardly directed portions 15 and the air pockets will be relieved because of the openina's 19. he tiles or bricks thus formed are very handy, strong, light, durable, and ctiicicnt in use.

.It is thought that the construction, utility, and advantages of my improved structure will now be clearly understood without a more detailed description thereof. The pres ent embodiment ot the invention has been disclosed in detail merely by way of example since in actual practice it attains the features oi ad *antage enumerated as desirable in the statement of the invention and the above description. It will be apparent that changes in the details of constrrurtion and in the combination and arrangement ot parts may be resorted to without de .iarting from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Havingthus described my invention what I claim as new is:

1. As a new article oi manu'tacture a core for a wet concrete form comprising a top plate having walls depending therefrom two of which merge into inwardly and upwardly directed portions which in turn merge into downwardly directed portions forming a box-like structure with the other walls of smaller dimensions than the box-like structure formed by the upper portions of the walls.

As a new article of manufacture, a core for a wet concrete form comprising a top plate having walls depending therefrom two of which merge into inwardly and upwardly directed portions which in turn merge into downwardly directed extensions forming; :1

box-like structure with the other walls of smaller dimensions than the box-like structure termed by the upper portions of the walls. there being provided openings at the junctures ot the tirstdnentioned walls with the plate and openings at the juncturcs ot the inwardly directed portions with the extensions.

;i. A form of the class described including a plurality 0t compartinents, a pair of cores mounted in each compartment, each core comprising a plate having side walls depei'iding from the edges thcreot in a bore like formation, two ot the walls merging into inwardly and upwardly directed portions which in turn merge into downwardly directed extensions Formingwith the other walls a second box-like structure, the second box-like structure being smaller in dimen sion than the iirst-hox-lilte structure.

-l-. A form ot the class described including a plurality oi compartments, a pair of cores mounted in each coinpartn'ieut, each core cmuprisinp a plate having side walls depending; lroni the edges thereof in a boxlllifl toru'uition, two of the walls merging into inwardly and upwardly directed por tions which in turn merge into downwardly directed extensions forming with the other walls a box-like structure, the second boxlike structure being smaller in dimension than the til-st box-like structure there beingopenings in the junctures of said two walls with the plate and openings in the juncturcs or said two walls with the inwardly directed portions in testimony whereof I aliix my signature.
