To all 'whom it may conoci/"a:

Be it known that ll, ALBERT V. Gunn, J r., a citizen of the United. States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented new and useful 'Improvements in Floor or Wall Grounds, of which the following is a specication.

This invention relates to improvements in iioor or wall grounds for the attachment of finishing material such as furring, trim, molding, carpet strips and floor screeds to structural material such as brick or stone masonry walls, gypsum, claypipe, plaster board, marble, concrete, metal lathing, slate or other structural material.

The principal objects of the invention are to provide a Hoor or wall ground which may be fastened and alined easily, quickly, and with the utmost security to the structural material; which shall meet the necessities of v all structural complications attendant upon modern methods of constructiong. which shall provide for certainty in the alinement and Vlevel and stability in the .application and adjustment ofthe finishing materials and shall entirely prevent injury to the structural material; which shall be of ex ceedingly simple and inexpensive construction; and which may be quickly made in a thoroughly practical manner from pieces of wood and metal ordinarily cast aside as waste in the course of building operations.

With the above objects in view, the inven-y tion consists in certainfeatures of structure and combination which will appear in del tail as the description proceeds, reference being had therein to the accompanying drawings, in which:

Figure 1 is an elevation, partly broken away and in election, illustrating the invention as used in connection with a brick wall lfor the attachment of window trim.' f

Figs. 2, it, and 4, are sectional yiews illustrating steps in the construction/and attachment of the improved ground.

Fig. ,5 is a l etail perspective view of a preferred form of nail-receiving element of the fastening ground.

Fig. 6 is an elevation showlng the use of scr/ap', material, such as metal lathing and wood blocks, for certain elements of the in vention.

. Figs. 7 4and 8 are sectional viewson the lines 7-7 and 8-8, respectively, of Fig. 6.

Fig. 9 is an elevation showing a strip of herring-bone metal lathing as one of the structural elements of the ound. y

Similar characters of re erence designate corresponding parts throughout the several views. n

llhe invention is not limited to use with any specific wall structure, but proposes to meet and overcome the nail impenetra* ble structures now commonly employedin building operations by providing for the application thereto of a nail-receiving block or strip for the securement, in va positive manner and in accuratel alined relation, of window frames, door rames, trim, molding, carpet strips, floor screeds andthe like at di'erent points as found necessary or desirable. By way of example Figs. l to d show the invention as used in connection with a brick wall 5.

The improved fastening ground consists generally of a nail-receiving element 6, preferably a block or strip of wood and which for convenience is hereafter referred to as a block, a metallic keying or `anchorii'ig element 7 which adjoi'ns the inner face of the block 6 and is suitably secured thereto and a hard-setting adhesive medium 9 by l' which the block 6 issecurely fastened to the wall. The elementr 7 is essentially of skeleton or open fabric form whereb it is ern-A v bedded throughout its extent 1n t e adhesive material and hence is securely grippedat all points by sgtid material and whereby the adhesive material also has gripping engagea, z

ment with the substantially entire over j inner face of the block 6 and preferably' with the sides or sides and ends thereof..

As shown and preferred the keying element 7 is composed of wire mesh which term is to be understood as generically including various similar foraminous materials such as wire gauze, metallic lathing, expanded metal or herring-bone metallic lathing. As constructed of wire mesh the element 7 is secured against the inner face lf the block itt 6 by nails or other headed fastenings; and said element is preferably, 'and as shown, of

greater area than the block whereby it Will project beyond the sides or sides and ends of the block. Thc'adhesive medium 9 may be of any suitablel plastic cementitious material, plaster ot' Paris beingi:l preferred. Such material is applied in su cient quantity to the preliminarily connected elements (S and 7 to spread over and securely engage a considerable surface of the wall; and the block 6 is pressed against the adhesive material while the element '7, pressed into the material by the block 6, becomes substantially Wholly embedded therein. In this Way the block 6 is directly anchored in and positively keyed to the plastic material and hence is secured With the utmost strength'.

Fig'. 2 shows the keying element 7 and the block` as preliminarily connected by the fastenings 8; and Fig. 3 shows the application oit the ground to the Wall 5. The block 6, in a preferred form as shown 'by Figs. 1 to 5, is formed in its inner face With the groove 10 and in its sides `with grooves ll to proyide lzcy seats, the adhesive material 9 being forced through the meshes or open spaces of the element 7 into the groove 10. ln these .figures the element 7 is illustrated as a strip ot' Wire gauze ot suitable mesh, the heads of the nails` 8 being large enough to engage the intersecting components of the gauze.

As shown by ligs. 5 to 8 inclusive, a scrap piece of metallic lathing 1.2 is used as the keying' element and an. ordinary block 13 of Twood is used asthe nail-receiving element, said blockv being secured to the latliing 12 bl staples la or other suitable fastening devices.

Fig. 9 shows a scrap piece of herring-bone metallic lathing 1.8 connected in any suitable manner to an ordinary Wood bloei; 19 as a further variation oie the improved ground.

lt is obvious that other forms of metallic keying elements-'having the characteristics oi the invention may be employed if desired.

ln the construction or the improved grounds it is. possible and. preferable to use scrap or Waste material usually cast' aside in the course of building operations; and tb reby a substantial economy in the in sic" cost oit the grounds and a further economy in their construction in sim may be effected.

.The grounds, constructed. as described, are

or ed einst the wmil at appropriate inlocations er which the usual coa apolicd to the i the ground ie bloeit G, the said cn project l; l coating and blocks being n "sin The grounds a a iv for the z ichment by nails in usuai manner of the n n material meager or trim. By way ot example Fig. l shows the grounds as carrying or supporting the frame members l5 and 16 of a door or Window opening, and a base board 17.

I claim as my invention:
