" The object of 'my invention is to provide a --furring strip anchor of very simple v`and durableconstrfuction, whichcan be made and sold at a low cost and to likewise set forthan'd i5 provide-a Amethod oflusing'vthe anchor.

`Moreparticularly;itfis my object tofpr'ovide! a furring strip, .which can lbe Vconvenn ientlya-n-d `easily adapted to a wooden 'form` in'such-manneraslto `leave anchoring 'elemen-ts projectingv therefrom and I adapted to be receivedin concrete or other plastic material* foriy yholding the anchor,l the mea-ns A4for fastening said device! to the form being such asvto permit 'the convenientandeasy removal e'f the vwood form members.

With these andfotherobjects in view, -my invention consists "inF the construction, arf rangement and combination of the various parts of my furring strip anchor, whereby the objects kcontemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

. 'The 4membersg;16 are. proyiaed with `-Awn -member 14 for instance.

For convenience .in reference to the turrina,- strip anchor, I b ave referred to the members 17 and 1 8, as the anchoring legs A, to the member 16, as the central member B, and to the members 24 as the furring strip ears C.

In Figure 4, I have shown my furring strip anchor installed in connection with another type of form used for clay tile flat ceiling construction with web reinforcing.

In this structure, the clay tile 32 is supported on the wooden form members 34 in such manner that the slab 36 may be poured and will have a flat upper surface, and will have the downwardly projecting ribs 36a formed between the rows of tile 32.

IVhen such a form isl used, the furring anchor is fastened to the wood form member 34 in the same way.

In Figure 5, I have shown the anchor in the form of the device shown in Figure 4;, after the conc-rete slab 36 has hardened and the wood form` member has been pulled away from the pointed members 30.

It is not desirable where workmen are on the job to haveJ the pointed members 30 projecting, as shown in Figure 5, and one valuable feature. of my present anchor arises from the fact that these members 30 may be clipped off to leave no projecting parts as shown in Figure 6.

The furring strip engaging ears 24 will then be folded up under the member 16 adjacent to each other and will be out of the Way and not subject to distortion and injury while other work is being done about the building.

Then when the time arrives to install the tiirring strips, the members 24: forming the furiing strip receiving ears C are straightened out until they extend away from the member 16.

It will be understood that these anchoring devices are installed in rows, so that the furl ring strip 38 may be inserted between a series of pairs of ears C, as shown in Figure 7, whereupon nails e0 may be driven through the holes 28 into the furring strip 38 for rigidly anchoring the furring strip in position.

Such a device has a. number of important advantages.

It is simple and cheap. It is readily and easily installed. It does not interfere with the pouring of the concrete slab. It furnishes an adequate anchor. There are no projecting parts after the slab has hardened,

which may be injured or distorted or may cause injury or inconvenience to the workmen. It may be used either on side walls oi ceilings.

I claim as my invention:

1. In a furring anchor, an anchoring element having a pair of stii legs and a member 'for connecting them and holding them in spaced relation, a pair of anchoring ears connected at spaced points with said element and adapted to normally lie in superposed relation to said member and each other and to be moved to spaced position extending away from said member, said member and ears having holes which register when such member and ears are in snperposed position and a headed removable securing device projected through said holes for supporting the anchor relative to a form.

2. A process for using a furring strip anchor as herein disclosed having overlapping furring strip supporting ears, comprising the securing of the anchor by fastening devices to a form, the introduction of a plastic body into the form whereby the anchoring legs et the anchor are imbedded in the plastic body and the body portion of the anchor is arranged at the surface of the plastic body witi the furring strip supporting ears in non-projecting position, the clipping of said fastening devices to permit the bending of said ears and the bending of said ears to projecting position whereby a furring strip may be secured between them and thereby supported.

Des Moines, Iowa, July 25, 1927.`
