Patented May 27, 1930 UNITED,A STATES FREDERICK M. vnNzrE, or* PHILADELPHIA, PENNSYLVANIA BUILDING STRUCTURE Application filed Marchy 12, 11926. Serial No.v 94,291.

This invention, generally statedrelates 'to a building structure and has more especial relation to a fioor or like construction of conV crete.` a

According to accepted methods 'of building concrete ioor and like structure it is quite difhcult and expensive to attach metal lath in place to receive ceiling plaster, usually requiring the services of'skilled mechanics.

It is conceded by architects generally that the present methods of applying plaster to concrete surfaces are unsatisfactory and give no permanent assurance ythat the work will remain in place. Work which carries with it a guarantee `is entirely at the risk of the contractor placing it and case after case may be cited where the most approved methods are carried out with the greatest care and skill, using only the highest grade of materials and have failed, causing great inconvenience to the owners and expense to the contractors.

After years of study and experiment and the expenditure of large sums of money, it has been positively ydemonstrated that nothing but a mechanical means of fastening the plaster in place will give the results desired and eliminate the possibility of any part of the plaster falling.

The leading object of the present invention is to overcome the above described disadvantageous features and provide a structure of the character stated in which a floor or the like is provided combining eiiiciency, simplicity, and cheapness, and in whichunskilled labor may be successfully employed in the erection of metal lath to receive the ceiling plaster.

Other and further objects not at this time appearing will be hereinafter referred to.

The invention consists of the novel construction hereinafter described and finally lustrating a vfloor structure in` accordancey with the invention in which the concrete is poured upon the forms.

Fig. 2, is a similar view with the forms p yremoved and the metal lath secured in posiof a piece of lform having nailed thereupon y a metal lath attachment device, prior to pouring of concrete. l Y f Fig. 4, is a similar view illustrating the concrete poured, the form removed and the metal lath in place. n

Fig. 5, is a view' in plan of one of the' metal lath attachment devices detached.

Fig. 6, is a view in cross section of Fig. 5.

Fig. 7, is a view in section taken upon the line 7 7 of Fig. 4.

Fig. 8, is a fragmentary view in sectional plan taken upon the line 8-8 of Fig. 6; and

Fig. 9, is a view incross section of a slightly varied form of metal latch attachment.Y

For the purpose of illustrating my invention l have shown in the accompanying drawings two forms thereof which are at present preferred by me, lsince the same have been found in practice to give satisfactory and` reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of the instrumentalities as herein shown and described.

ln the practice of the present invention the usual forms l are erected and supported ory shoredup by beams 2, as seen in Fig. l. yfhe next step, as best seen at the right hand side of Fig. l, is to secure lupon the upper faces of the forms `1, a plurality of spaced, metal lath,

attachment devices, best seen in Figs. 3 .to 6. Each attachment, which is designated 3, is composed of thin metal stamped from a single piece of material to a shape which may be likened to thatV of a boat, see Fig. 5, and each is secured in inverted position as by a nail t, to the upper face of a form l, best seen in Fig. 3.- The opposed ends of each attachment 3 are tapered as at 5 and the opposite sides of the attachment are bent upwardly in opposed fashion 'to provide vertical side walls 6 each lterminating at its top in a laterally disposed dan e 7. The outer edge of each lange7 is notc ed at 8, see Fig. 6. The side walls 6 of each attachment are each vgroovedvertically as at9, see Fig. 6. The extreme lower and opposed parts, .as designated fat 10, are notched, see F ig. v6. Extendedlaterally across each attachment and engaging the lower notches 10, the vertical grooves 9 and notches 8 are a pair of members 11 of Wire. engage beneath an attachment and in notches 10; the ends of the Wire then extended upvwardly Within grooves 9; then aroundthe flanges 7, including notches` 8,'the free ends ofl av wirebeing extended laterally in oppo.

site directions, see Fig. 7 The concrete12 having been poured to form the door, obvi- Fig. 4. lVhile the abovedescribed struct-ure l is adapted for any desired-form of floor, ceil-l ously the metal lath attachments 3 are iirmly embedded therein. This position of parts is seen in Fig. 1. Vlith set of concrete 12 obtained, the forms 1 are removed thusexposupon the underside of the floor a plura ity of spaced attachments 3 with the Wire parts 11 extending across each attachment.

It-is to be understood that with'tlie removalv of forms 1 the nails 4 are left hangingvwithin the cavities of ther attachments v3. Metal lath of any desired type, as for example wire mesh l13, is now positioned to accept-ceiling plaster 14, see Fig. 2. In securing the wire mesh 13 to place the sameis lwiredasl atflto the exposed wire members 11 as best seen in ing orlike structure it is especially eficient where ceiling beams are formed,`as shown in the drawings, because the metal lath can bev stretched taut and very easily wired to the attachments which latter may be positioned upon both side and vbottom Walls of a beam.

Referring now to Fig. 9, the construction is the same as that `shownin the foregoing described Vfigures except that the cross section` of the attachment is substantially Wsha'ped. Such cross sectional area admits of the pouring of additional concrete the advantage of which is readily apparent. By-W-shaped I mean that the central walls 3 and outer walls 6 of an attachment are all inclined with respect to vone another.

Among the advantages to be claimed, meni tion may be made of the following:

1. Absolutely permanent-no possibility of falling plaster. -V A 2. Unlimited guarantee-plaster willV re-v main while concrete lasts.

3; Can be lasteredover immediately--no'A waiting for c rying.

4. Easily installed. 5. Moderate in cost. r It willnow be apparent that I have devise a novel and usefulconstruction which embodies thefeatures of advantage enumerated as desirable in the `statement ofthe invention These wires are first caused to.

land the above description andrwhile I have An anchorage for lathingsheathing adapted to be embedded in concrete`con'struc tion during the molding thereof, which comprises a generally concaved Velongated inverted shieldV which is substantiallyrboatshaped considered longitudinally and is of Vsubstantially W-shaped cross-section, said shield being 'of seamless metal and adapted i kto be embedded in the concrete with the edges` thereof flush with the outer-surface, an an-' chor wire extending across the edges of said shield and around said shield and having transversely extending terminal anchor mem-y bers said shield having an aperture extending through vthe top thereof for the reception of fastening means including a nail passing i through said aperture andattached to said Vlatliing sheathing, whereby said shield and transverse anchor member may be secured to the inner surface of concrete molding forms.'`

In testimony whereof, I have hereunto signed my name.
