` solange. (o1. vs -12) 'UNITDjiSTAf-es i Thisinvention relates to new and .usefull improvements in `a. hollow cement block.. i

`The invention has foran object the construction of a block as mentioned which is characterized by the provision of an open meshreinforcement material having a bottom and side walls, and.l supporting?` aA moisture-proof plate extending across the top edges of the side walls and held together in a unit by cement covering the inner and outer sides of Vsaid open mesh reinforcement material and plate. A feature of the construction is that the block will be light in Weight, and since it is hollow it will oat;iit will also be water-proof because of its cement construction and moisture-proof because Yof the moisture-proof plate on one face, 'said face preferably shouldbe used as thefrontface.

Still further theinventionproposes the construction of a block as mentioned in thel previous paragraph which' is arranged in sucha manner that the front face may be finishedornamentally into different effects-as desired.

Still further it is proposed to` produce a block as mentioned which reduires no backing or furring and which may be manufactured without resorting to pressures.. I

Still further the invention proposes tolsolarrange the block that it may be built with or, without a form though of course, a form williexpedite its manufacture.` 1 f 1 i Stillifurther the invention proposes the teaching of a method by which the `block may be manufactured. l 1J 'Another one ofthe objects of `this Vinvention is the construction of 'a block which is characterized by a pair ofmoisture-proof plates slightly spaced from `each other and in one ofthe walls thereof and in other respects resembling the block previously described as `to characteristics.

lStill further they invention proposes *the construction of a device as mentioned which is simple and durable and which maybe manufactured andsold at a reasonable cost.

For further comprehension of the invention, and ofthe objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:-

Fig. 1 is a perspective view of a hollow cement block constructed according to this invention.

.Fig. 2 is a transverse sectional View taken on the line 2.-2 of Fig. 1. i y Fig. 3is a perspective view of the open mesh material, illustrated in Fig. 2 used in the manufacture of the block.

Fig. 4 `is a perspective View of a form in which the blockf may be 'conveniently manufactured.

Fig. 5 is a sectional view similar to Fig. 2 illustrating a'modication of the invention.

Fig. 6 is a similar view to Fig. 2 but showing another modification of the invention.

The hollow concrete block according to this invention includes open mesh reinforcement material I0 having a bottom I0' and side walls I!!a and associated with a moisture-proof plate II, such as glass, extending across the top edges of the side walls and heldin an integral unit by cement I 2 arrangedupon thesides of the open mesh material and the plate.

Moreparticularly. the open mesh material IB A isconventional reinforcementmaterial used concrete reinforcement constructions formed from sheetsstamped or in any other `manner formed with openings.

More particularly, the open mesh reinforcement Il) hasitheside walls. Illa formed with inturned bent edges Il)b upon which the moistureproof plate II is supported during the manufacture of the block. `Sirice'the open mesh material is of open construction some of the cement I2 i will enter from vthe I. inside and extend to the outside as illustrated inFig. `2 of the drawing, so that in-reality the reinforcement material Il)a Will be imbedded in the hollow concrete cement form. The side of the block provided with the moisture-proof plate II constitutes the front-of the block and may be finished in any suitable fashion. For example a tile I3 is cemented together with it. `While this particular design is shown it should be borne in mind that the cement I2 itself may be finished in a satisfactory manner or any'other type of finish known at the present Cal time orto be discovered in the future may be applied to the block.

In Fig. 6 the tile has been substituted by an ornamental layer of concrete cement I3 on which any suitable design may be formed. i

The process for manufacturing the block consists in theprovision of a form such as illustrated in Fig. 4 including a body consisting of a bottom wall I4 and the side walls I5. This body is open at the top. The open mesh reinforcement material Il) illustrated in Fig.v 3 may be set into the body and the parts are of such size that there will be a slight area between the outer faces of the reinforcement material I and the inner faces of the body.

The rst step in the manufacture of the block consists in placing cement material within the body upon the bottom I 4. Next the open mesh reinforcement material is placed within the body and cement is filled in between the mesh reinforcement and forced into the reinforcement and the body by a suitable tool so that some of the cement will cover .the inner side-of thereinforcement. In anyevent it is proposedto. cause the cement to encircle the bottom and the sides, also the inner sides of the open mesh material. The next step in the process consists in merely pressing the moisture-proof plate H in position upon the inturned ends Ilb. Then cement is added at the top and in this manner the hollow block is concluded. 1

In Fig. another embodiment of the invention is illustrated in which an arrangement is provided wherein the. hlbck i-sforrned- `with apair of moisture-proof plates II and `I ta Vslightly spaced from each other. More particularly the block includes open mesh material'. me having a` bottom wall I 6d and side walls |02: The upper free-edges Illf of. the side wall-s are turned inwards. A flange Ilis extended `inwards frorn'the side walls of the open mesh material Illc and is spaced slightly downwards from the inturned top edges If. This ange. Illg extends inwards to a greater' distance than the inturned edges- IIlf. arrangement is such that the moistufe-prooi plate IIa may be supported upon the flanges ills- The compass of theplate I la is of' a smaller size than the area between the inturned. edges. ttf so, that the plate may easily assume its. position.. The top moisture-proof plate I.' I is of a sizey so as to be capable of resting upon the inturned edges I0?.

The block is manufactured with the cement t2 engaged upon the outer walls of` the. reinforcement material and ever:- the. top of: the. tnp mois.- ture-proof plate I: tg: Thee arrangement. is such that there is a small area IE- between the plates II and I Ia which serves .to prevent or retard conduction through the front'` wall of. the block.

The process of manufacturing the block illustrated in Fig. 2. consistsin arranging the; open mesh reinforcement material. III.c within the form, such as illustrated in Fig. 4*, in amanner so that there is cement upon the inner outer faces of the sides and bottom thereof "Thenv the plate I I.u is placed in position; and n'al-l-y cement is engaged over the top of the plate II' and causedtojoin with the cement at the. sides. The front. face of the block maybe nished with a tile, such as tile I3.A

In actual' use these waterproof cement. blocks maybe alsoA lled cementy or other suitable material through holes by boring communicating holes between the adjacent blocks after they are stacked to.y form a wall', partition, etc.,

While I have shown andi described the preferred embodiment of my invention, it is. to bei understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modications coming within the scope of the invention as dened in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent isz- 1. A hollow cement block, comprising open mesh reinforcement consisting of mesh Inaterial having a bottom and. side. walls in the form of a boxl with an. open top, a glass plate extending across the top edges of said side walls, and cement covering the inner and outer sides of said open mesh material and said plate and binding these parts together into a hollow unit.
