Application filed Deccmber 21, 1925. Serial No. 76,631.

ments and certain details of construction will appear more fully in the following description illustrated by the accompanying drawings. I I

The annexed drawings and the, following description set forth in detail certain means embodying my invention, such means constituting, however, only a few ofthe several forms, in which the principle ofthe' invention may be embodied. i

In said annexed drawings: p Figure 1 is a plan view 'ofa fragmentary ortion of the main metallic support formmg part of the fire-proof floor construction, the usual expanded metal utilized therewith, andmy improved clip for supporting and securing the nailing strips.

Figure 2 is a vertical section, taken longitudinally of the metallic floor support or joist and in the plane indicated by the line IIII, Figure 1;

Figure 3 is a vertical, transverse section, taken in the plane indicated by the line IIIIII, Figure l;v j v Figure 4 isa view similarto Figure 1 in which the strip-holding clip is turned 909' from the position shown in Figure 1, thus illustrating the application of the improved clip to a situation whereyit is desired that the floor shall run in the direction opposite to that in which it would run if laid upon the base shown in Figure 1 Figure 5 is a view similar to Figures 1 and 4, wherein the clip isturned thus illustrating the adaptation thereof to a sit nation wherein it is desired'that the flooring shall run diagonally; I I t Figure 6 is aview similar to Figure 2, after the concrete has been poured and the flooring has been-laid Figure 7 is a view similar to Figure 1,

but showing modified means for fastening the strip supporting clip to the expanded metal; i Y

Figure 8 is a 'verticalsection taken longitudinally of the supporting joist and in the plane indicated by the line.VIIIVIII, Figure 7; i v

Figure 9 is a Vertical, transverse section, taken in the plane indicated by the line IXIX, Figure 7; 7 V Figure 10 is a view similar to Figure 8, after the floor has been completed; and

Figure 11 is a perspective view of my new and improved strip-holding clip.

Referring particularly to the annexed drawings in which the same parts are indicated by the same several ordinals in the respective views, I indicate by the ordinal. 1

any conventional form of main support for a reinforced fire-proof floor construction; by the ordinal 2 the usual expanded metal mounted upon and secured to the main support 1; by the ordinal 3 my new and improved chp, a stamped article, which isisccured to and above the support 1 and expanded metal 2and is provided with means for supporting and holding the nailing strips'4 above the expanded metal 2 and, spaced therefrom such a distance as to bring the top of such strips 4 substantially flush with the top of the concrete 6 which is poured over and around the metal 2 and in and around the clips 3. These strips 4 are utilized as anchors for nails 19 or other suitable securing means driven through and holding the wood floor 5.

The usual means for securing the stripsupporting clips have been wire ties 7 such as illustrated in Figures 7, 8 and 9. My improved clip is designed: to provide for'the use of the ties 7 or for theuse of a new and improved holding member 9, illustrated in Figures 1, 2, '3 and 6, if a type of main metallic support or joist is utilized allowing for the use of such holding memberS). The necessary type of joist to allow for the use of such a member 9 must be provided with a is simply a wooden wedge of the approximate shape plainly shown in Figures 3 and 6, and of a width greater than the mesh of the expanded metal 2. This resilient wedge 9 when driven downwardly, simply by the stroke of a hammer, tl'u'ough the mesh of the expanded metal 2 and between the bars 8, will become securely fixed to the latter'so as securely to retain the expanded metal 2 and, it means are provided in the clip 3 tor receiving the wedge 9i'andallowing the same to be driven therethrough so as to become fixedtherein, then this wedge 9 will serve also to retain the. clip 3 in position upon the expanded metal 2 and the joist 1. I provide such means in the clip 3 through the medium of a loi'igiti'idiual slot 11 termed in the base 10 ot the clip. For the purpose of allowing the clip to be fastened in various relatively angular positions to provide for the laying of the flooring in various directions, I provide a plurality of longitudinal slots 11 in the base ot the clip 3, each slot comprising two inwardly tapering end portions and a central portion 12 which is a common center hole for all of the slots,'the several slots 11 being relatively angularly disposed, as i)lainly shown in Figure 11. This construction 01 a plurality of slots 11 affords the adjustabil ity of the clip and, hence of the laying of the floor, plainly shown in Figures 1, at and 5.

The detail construction of the rest of the clip 3 comprises relatively right-angular side members struck up from the blank from which the clip is stamped, these side members 15 being perforated to form. the openings 14, thus ati'oiding extensions 13 of the base 10, serving both to allow tor the flowing of the concrete in and through and around the clip 3 and affording the members 13 to which the ties 7 can be secured, it the clip 3 is secured to the expanded metal 2 and joist 1 in the manner shown in Figures 7, S and 9. The upper corner portions of the side members 15 of the clip 3 are bent inwardly to form ears 16 upon which the nailing strip 4: is supported in a position somewhat spaced from the body member it) of the clip. Adjacent the upper edges of the central portions of the side members 15 I form holes 17 adapted to receive nails 18 by means of which the nailing strips a are fixedly held in position upon the supporting ears 16.

No claim is made in this application to the particular assembly of connecting means for structural members, of which the hold ing member 9 is a part, the same being shown, described and claimed in my pend ing application Serial No. 79,530.

The steps of form-ing the floor and the use of the improvements herein described and shown in the accompanying drawings are then as follows: The joists of other main supports 1 are first positioned upon their end supports. The expanded metal 2 is then laid and secured by the usual ties to the supports 1 or, if the wedge 9 is utilized,

the clips 3 are positioned in the desired angular relation to the supports 1, and the wedges 9 driven down through the slots 11 and through the expanded metal 2 and wedged into the spaces between the bars 8, thus also looking the broken or distorted ends of the expanded metal between the opposed faces of the bars 8 and the adjacent sides of the wedge 9. If the wedge 9 is not utilized, the clips 3 are secured by means of ties 7. Then the nailing strips 4 are mounted upon the ears IGand secured fixedly by the nails 18. Concrete 6 is then poured over and through the expanded metal:

and in and around the clips 3 and screeded somewhat below the top surface of the naiL ing strips at, as shown by space 20, Figures 6 and 10. After the concrete 6 has set, the floor 5 is laid and fastened by means of nails 19 to the strips 4, as shown in Figures 6 and 10.
