IIy inventionieiatest impr0vements in building constrncticns, and it consists inthe emnbinations, ccnstrnctions, and arrange- 1nents herein described and c1aimed;

An object of niy invention is to provide a device f0r nse wit-h ccncrete CBIIIIg'S means of which snspensicn bars er rode fcr 1netallathcr similar "ceiling 1naterial rnay be quick1y and econc1nically applied.

A nrther cbject is to provide a device of the type described in whichthe snspendiig faciiitating the rapid and accurate placing of said reinforcingrods.

A 'urther object is te provide 1netahfor1ns which in themselvesform a support for the reinficrcing rode, therebyobiiating. the use of additional supporting members,

ther cbjectjs and advantages will appear in the olicwing SPGCfiLQ1T{ZLII(IIIG novel features of the invention wilibe prticularly pcin ted out in the appended claims.

My invention is illustratedinthe accom panying drawings, formin-g part of this ap: plicatin, in which v Figure I is a side view of one ofthe metal :E0r1ns, the wooden form "upon which it is supported heing shown in secticn,

Fignre2is a sectionai view along the line 2-2 of Figure 1,

Fignre 3 isa sectional view through the concrete portion of the ceiling and the woeden form boards before they have been re1ncved,

Figure 4 is an enlarged detailed view showing a portion of the concrete ceiling, the suspending n1eans and the metal lath, the meta1 form and the anchor being shown in elevation,

Figure 5 is a view of a modified form of the device, and

Figure 6 is a diagrammatic view showing the staggered arrangement of the meta1 0rms f0r supporting the reinforcing rods.

Reierring now to the drawings, 1 indi cates a concrete floor which is cast en a form such as a wooden form 2. This is supported inany sutable mannen-as by thesupports 3; Carried by the form 2 areinverted 1neta1 trcnghs t which arespaced apart and which may be rernoved after the concrete is set. Between these troughs, I p1ace a series of cup shaped 1neta for1ns like that shownat 5. These f0r1nsare the general shape shown in Figure 6. The tops 5? are preferablyflat. The sides have grceves 6 pressed thereinand the bottoms have cpenings 7, Anchoring de- Vices like that shown in Iigure 2 are pre- Vided. These anchoringz devices consist of a central bowed porticn 8 which is within the form 5. The ends of this portion are prolcne;ed and passed thrcugh the opening 7 and then are bent npwardly a nd iie in the groeves Abevethe upper flat surface 5%, theseanchoring devices are bent outwardly te ferm guide members 8.

Bef0re the anchers are placd arcnnd the form 5, asnspendingmember 9 in the form cf a locp is passed over one end of the anchor and over the centr-al port1on 8. Th1s -I0op Fignre 4, er it ina-y beol' any suitableshape to receive tlieparticujiar nenaber which itis designed to support. In Iignre 4 I have shcwn"thelccp 9 as slxppcrting a channel ron 01 bar 10. In this figure theloop is el ongzted. In Figure 5 the opening in the loep may be circuiar te receive acircnlar rod or penci1 11.

In operation, the 0r1n boards 2 are erected, thetr0ughs 4 placed in position, and the forms 5 are placed between the tioughs: Theyai*e prefejrably arranged in t wo or more r0ws, as sh0wn in Figure ;6 the iorns of each row heing stagg'ered with respect tothe adjacent r0w. In order to h0ld the metal forms to the wooden form, I preferably drive a nail 12 down through the top of the form 5 so that there is no danger of displacing the form when the reinforcing rods are being p1aced 0r when the concrete is being poured. VVith the 1neta1 forms arranged as shown in Figure 6, the reinfcrcing 10ds 13 are very easiiy applied. The Haring arrns 8 of the anchor form guide' n1eans so that it is only necessary t0 drop the rode 13 when the arnrs Wil1 guide thern te the tops of the for1ns 5,

where they rest. This obviates the necessity of having additional supporting n1eans for the reinforcing rods.

When the forms 5 are applied and nailed to the wooden form 2, the movable snspend ing member 9 will be pushed up into the position shown in Figure 2. When however, the concrete has set, and the form boards 2 are removed, the snspending member9 Will now drop down and Will slde to the end of the bowed porton 8 and remain suspended. All that is necessary in order to hold the bars 10 or the pencil rods 11 is to pass the1n through the loop, as shown in Figure 1.

In constructions Where there is consider able weght, it is advisable to use channel irons 10. The metal lath 14 may be wired or otherwise secured to the bars 10 01' to the pencil rods 11, as shown at 15 in Figure5.

\Vhen the form boaids 2 are rernoved, it

is not necessary to remove the nail 12. The

letter, however, does not interfere with the suspending member 9, since it is placed to-- Ward one end and one side of the form 5, as shown in Figures 1 and 2. One nail is suficient to hold the form in place, and it is an easy matter to take off the form boarcls since the mail is coxnparatively small.

Tlie construction described above has a number of important advantagcs. As stated,

it forrnsa, means forsupporting the rein forcing rods and for quickly placing them in position. It enables the for1ns 5 to be placed directly on the form boards 2 since the suspencling member 1noves Within the form 5 to perrnit it. It obviates the necessity of tying the bars or rods to the suspendng member, but permits them to be thrust throughthe aligned loops, where they are held securely. The flaring outwardly of the 1r1ns 8 serves the double function of guiclng the reinforcingrods into their positions on the tops of the f0rms 5 and then, when the concrete has been poured, they have tl1er normal functions of anchors for the suspendng means 9.

I am aware that metal for1ns like that shown at 5 having suspending means is not broadly new, but ordinarily the lath or rods have to be secured to the suspendin means by tying or in some other way end do not consist of loopls through which the bars or rods may he t rust, n01 do the forms serve the purpose of supports for the reinforcing rods nor do the anchors serve as guides or putting the rods in place.

I claim: 1. A building construction, comprisng a concrete ceilin having a plurality of cup shaped metal or1ns embedded in the lower surface thereof, certain of said or1ns being in axle alignment, 2i U-shaped anchor '0I eaoh form, said anchor having a central bowed portion disposed within the form, and anguiarly disposed guide portions ab0ve and to one side of the top of the form, and a sus" pending loop carried b y said central portion.

2. A building construction, comprising u concrete ceiling having a plurality of cupshaped lnetal for1ns embedded in the lower suri'ace the1e0f, certein of said forms being in axile alignment, a U-shaped anchor for each orn1, said anchor having a central bowed portion disposed within the form, and angularly dsposed gude portions above and to one side of the top of the form, and a suspending loop carried bysaid central portion, said loop having en opening for permitting an upward movexnent wthin the. form or a downward movement to bring the loop belo.w the lower edge of the form.

3. Abnildingconstruction, co1nprsing a concrete ceiling havng a plurality of cup sh1ped metnl fornis embedded in the lower surface thereof, certain of said forrns being in axile alignrnent a U-shaped anchor for each form,- said anchor having .a central bowed portion disposed within the form, and angularly disposed guide portions aloove and to one side of the top of the form, and a suspending loop carried by said central porton, said loop having en opening fox permitting an upwrd movement withn the form or a downwardmovement to bring the loop below the lower edge of the forrn and a la thsuspending memloer arranged to be received and be suspended by the loops of certain of said aligned forms.
