Description

Patented Nov. 1l, 1930 UNITED STATES CHARLES E. JONES, F GRIFFIN, GEORGIA CONSTRUCTION UNIT Application filed April 18,

This invention appertains to improve` ments in construction units generally, and more particularly to a building block or brick type'of such units to be employed 1n '"5 erecting walls of buildings and the like. n

In the building practice, one of the ma]or difficulties arising therein has been the neces-- sity of making attachments of various kinds and descriptions directly to the concrete or brick walls of buildings, as in the case of attaching wood or metal furring strips and lathing thereto for plastering and other similar purposes, or in the securing to the same of cables, conduits, pipes and the'like, and which has heretofore been accomplished only at great inconvenience, labor and expense by the drilling of holes :in the walls or the insertion of metal clips andthe like in the mortar joints between block or brick units formingthe wall. 'Y

Therefore, it is an object of the present invention to provide a construction unit, wherein a means is provided which will overcome the difficulty aforesaid in a highly efficient manner andmake it comparatively easy to secure nails, pins and othertypes of fastenings in the same without, in any way, resorting to the drilling or chiselling of holes therein for the purpose, vand at the same time, eliminating any necessity for the'employment of extraneous means for completing the securement of the fastenings in place. Another object of the invention is to provide construction units as herein characterized, which will readily admit of the driving or screwing of nails, pins or screws and the like into units madefrom hard and ordinarily impenetrable materials such as brick, concrete blocks and the like, with a facility heretofore obtaining only in the securing of fastenings of this character in materials of a softer nature. c

With the foregoing' and other equally important objects and advantages in view, the

invention resides in the certain new and useful construction and arrangement as will be hereinafter more fully described, set forth in the appended claims and illustrated in the accompanying drawings, in which:

1929. serial, No.l 356,170.

Figure l is a perspective view of a concrete block or brickwall construction, showing'apraetical embodiment and application of the invention;

Figure 2 is a verticaltransverse' section through the wall and a -furring lstriporthe like securedthereto in accordance with the invention; 'i Figure 3 is a perspective View of a slightly modified form of the block or brick per se; Figure 4 is a similar` view of another slightly modified form of the block or brick; and

Figure 5 is another similar- View `:of a further modified formthereofi Referringto the drawings, wherein like characters of reference designate corresponding parts throughout the several views thereof, and more particular to Figures "Y1k and 2,

theembodiment of the invention, as shown therein by way of eXample,`is constituted iin a building unit l0, of a hard and ordinarily impenetrable material, such as concrete, baked clay and the like, which whenmshaped or molded, has one or more slots l1 formed therein and opening through yat least, onefof the opposite side faces ofthe same, and eX- tending either horizontal-ly orV transversely thereof, or both, as may be desired.` Each slot l1 in a building unit 10 is made with its opposite side walls convergingtoward one another inwardly of the unitbodiesso that the same is substantially triangular in: cross section and comparatively narrow vwith respect to its depth of penetration'.V Also, the slots 11 will be preferably formed in the plane of the horizontal and/ or transverse centers of the unit l0 sowas to not unduly` weaken the block or brick structure.

In use, the units 10 will be laid in the usual manner to form a wall or other structure, with the slots 1l therein faced inwardly of the completed wall, in thev case ofthe attaching thereto of furring strips or the like a, as shown in Figures l and 2, for plastering and otherwall finishing operations, lor outwardly, as in the caseof the attaching `of the strips'a for pebble-dashing or other exterior finishes. The arrangementlof the slots 11,in

Ibuilding units of the nature mentioned, also Y i Without further description, it .is thought provides an excellentmeans for the installation of chimney and wall flashing as will be obvious. v f In 'effecting an attachment of building elements,- suchas thefurring strips a in position von a wall, fastening elements such as the nails v b, will be driven Vthrough the strips a in the usual vn ia'nner-and the points of the nails b allowed to enter the slots 11. Now, asthe nails b arey driven to completely secured'po-l sition, the pointed endsl thereof willpene-V trate the gradually constricted inner side` Vwalls of the slots 11 and will be firmly held therein against displacement by the frictional.

guishedwfromtheslot 1 1 .formed coextensive-V .ly with the face in the longitudinal direction,

as shown in Figures 1 and 2.

As shown in Figure 41, instead of one slot Y beingformed either longitudinally or transversely, or.\b'oth',ofonefacejof 'a block or brick, a series of relatively short slots 11 may be substituted therefor', and these will preferably be disposed in'equidistantly'sp'aced re- .'lation lone (withrespect to the other, but unc equally so, lifv occasionV demands. Y Y

vInFigure 5,fthe blockor brickV lcillustrates l*an arrangement-of a series of alternately disposedshort slots 11c and circular openings or punctures 12, which are preferably laidy in aligned relation along thelongitudinal/centerof oneface thereof, substantially as shown.

' In each lnstance of these modified forms of.tlie.invention'the slots 11?, llband 11, and

f the. circular openings or punctures 12,. are l tapered'inwardly of the block or brick face,

so that-,tha same securement of the fasteningstofbe engaged therein willV obtain. v

that thefeatures and advantages ofthe in- 'ventionl will be vreadily apparent to those skilledin the art, and` it will' of course be understood that changes in the form, proportion and-minor details .of construction may be resorted to, withoutdeparting from the spirit ofthe invention or its scope as claimed. @Iclaimz f. 1.
