sunFAcEFlNlsl-IING FOR FLOORS, CEILINGS. ato.

To all uihom, it may concern: v l

Be it known that I, JOHN J. BLAGKMAN, a citizen of the United States, residing in New Britain, in the county of Hartford and State of Connecticut, have invented certain -new and useful Improvementsin Surface-Finishing for Floors, Ceilings, &c., of which the followlng is a specificatlon. -v

This invention relates to an improved flooring-block for hard-wood orparquet floors.l

The obj ect of the invention is the rovision lof an-improved surface or finish or iioors made up of blocks, each of which blocks in the present improvement comprises two registering parts of substantially the same dimenslons interlocked by sliding one upon the Y other, one part constituting a complete base for the' facing member and ada ted to be first secured by suitable fastening evicesin position to the underflooring vor retaining structure and the other constituting a complete facing-plate for the base,4 fully facing 4said base and adapted to be subsequently applied to such base, the two'parts or plates comprising a single complete block, the up er flat part of which constitutes the surface 'sh of the floor or structurey to which the block is ap' hed.

A further object of the invention is the rovision of an improved wood iiooring-b ook comprising two members or plates, one a base and the other a surface fmsh or top linterlocked with each other by a series of tongues and ,grooves or dovetails, the4 top fully facing the base and the two partsy or members forming a single, com lete, and independent block with the grain o thev top crossing the grain of -the base, so that vthe top isheld in position Without liability of Warpin or. dislocation, the construction being suc that an inexpensive wood may be used for the base,. while Specication of Letters Patent.

' of two of the members or Patented March 1 3, 1906.

4 is a pers `ective view ofthe blockor section with t e top severed on a diagonal line to illustrate the manner in which the dovetalls secure theparts together. Fig. 5 is a perspective view showing the block cut to 4 ave a hexagonal shape. Fig. 6 is a section plates, illustrating the form of dovetails shown in Figs. 1 to 5..'

Fig. 7 is a section showing a different form of dovetail. Figs.- 8 and 9 are respectively perspective views of the top and ase members or plates, showing another form in which dovetails are employed for uniting the mem# bers; and Fig. 10'is a section of said top and bottom united by the form of dovetail`shown in Figs. 8 and 9. l

Similar characters of. reference indicate corresponding parts throughout the different figures of the drawings.

This improved flooring-block 2 comprises a top or top plate 10 and a'base or bottom plate 6, the two forming a-complete independent block or section, which is secured to an under'iloor or other retaining structure.

The base-plate 6 may be rectangular or of'- any other desired form, the top corresponding in sha e thereto, and is first securely fastened to t e under floor or other supporting structure in any desired way, preferably by means of screws 7, passing through :perforations 8 in ribs or tongues 9, Figs. 3 to 6, or 15,

Fig.'7, or 18, Figs. 9 andlO, of the said baseplate. These ribs or'tongues may be of vay rious forms-as, for instance, of ogee forma- ,tion-as illustrated in Figs. 1 to 6. This form is more particularly described and claimed in my divisional patent, No. 683,009, dated September 17, 1901, or the maybe of zigzag or stepped formation, as i ustrated in Fig. 7, or just a plain dovetail, as illustrated in Figs. 8, 9, and 10. The ribs or tongues may be readily produced by. machinery. In-

tervening each pair of tongues or ribs is a groovek 9 for the lreception of a corres ondmgly-shaped rib of the companion mem er of the block.

`The top or facing member orplate 10 of the section or block is shownl corresponding IOO in dimensions with the base-plate, so 'as to fully face the same, and is likewise rovided with a series of ribs or tongues 12, Ifigs. 1, 2, 4,to 6,or 14, Fig. 7, or 17, Figs. 8 and 10, and which ribs or tongues correspond to the forin of the ribs or tongues of the base-plate, and therefore fit and interlock therewith.

Preferably the base-plate 6 is provided with a series of ribs, five being shown, and Io the top plate 10 with a similar number of grooves, or vice versa, since by this construction the top plate may be severed on a diagonal line, as indicated at 13, Fig. 4, orboth members may be thus severedto cause them i5 to fit into corners or other places (see Fig. 1) without liability of detaching one. plate from the other plate, as might be the case were but one or two ribs or projections employed. The dovetails are shown of the same Width 2o from end to end, this being the preferable construction, since the to can then be slipped on from either side uring the laying of the floor.

In Fig. 7 the to or surface member or 2 5 plate 1() of the bloc is shown provided With a series of separated ribs or projections 14 and the base or bottom late with a similar series of ribs 15, each rib eing of a stepped or zigzag form, as indicated at 14 and 15', respec- 3o tively, at its sides to form an interlock when the two plates or members are united.

In Figs. 8 9, and 10, as hereinbefore stated, the top and bottom members are each provided With a series of plain dovetails 17 18,

respectively, for interlocking the two parts together.

In the use of all the forms of my present improvement the base-plate 6 is first firmly secured to the under floor or other retaining- 4o surface, then the dovetails of the top or surface plate 10 are inserted into the grooves of the base, whereupon the top can be readily slid into position fiush at its sides and ends With the side and end walls of said base-plate.

4,54 Thus the top member or plate fully faces the bottom member or plate, the two members forming a single complete block and when laid with other companion blocks of similar formation forms the complete floor.

5o The present improvement, it will be seen from the foregoing, comprises a finished complete block, one flat part of which' constitutes the surface finish ofthe structure to which it is applied and which block is composed of 55 two independently-formed readily-separable registering parts of the same dimensions, dovetailed. interlocked by sliding one upon the other, one constituting a complete and inde endent base adapted to be first secured.

6o in p ace to the retaining structure or underflooring by screws or similar fastening means and the other forming a complete and independent facing-plate, fully facing said base and to be subsequently secured to the base by sliding it on such base, so that the blocks the base-b can be readily secured in place by a carpenter without the use of cement or other material of a like nature.

The base or under plate could be a metal block if a fire-proof lining were desired, while the upper plate was of wood, the ribs or roj ections of such metal plate being forme integral therewith by either casting or shaping them up from the body of the plate.. The improvement is, however, particularly designed as a surface finishing in which both the face and base plates are formed of wood and is especially organized as a surface finish for floors.

The blocks made u and attached in the manner indicated cou d be used to give the same appearance as a parquet-fioor to various things-as, for instance, the ceiling of a room, &c., or as a table-top, &c.

When both plates are constructed of wood, the lower plate will have its grain crossing the grain of the upper plate, so that the two plates when interlocked in proper position or use will operate one to retain the other against warping or buckling.
