FLOORING.

Specification of Letters Yatent.

Patented Nov. 18,1913.

Application ted January 2, 1912. Serial No. 668,805.

To 7l Iwho/n 'it may concern:

Be it known that I, JOHN C. DUN'roN, a citizen of the United States, residing at Grand Rapids, Michigan, have invented certain new and useful Improvements in Flooring, of which the following is a specitica-- tion.

This invention relates to flooring.

The objects of this invention are to provide an improved construction of wood flooring in which the end grain of the wood is eftectively presented, and the small blocks or sections -arc securely joined together and presented in pleasing form or design, and liability of distortion or warping is overcome.

Objects relating to details and economies of construction will definitely appear from the detailed description to follow.

Preferred embodiments of my invention are illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure I is a section of flooring as made up embodying the features of my invention in its simplest form, four of thesquares being here joined. Fig. II is a detail view of the assembling of the planks or boards constituting one step of the process ot' producing my improved iooring. Fig. III in dicates the method of slicing the sections from the end, which may be the next step of the process in its simplest form. Fig. IV shows an additional step of the process in which the end sections are sliced into strips. Fig. V shows the next step ofthe process in which tapered dovetail tongues and grooves are formed on the block sections, the position of alternate strips being end for end when compared with the strip improvements in as -cut ott. Fig. VI shows one of the complete squares made up ofthe blocks constituting a single square section of my im*` proved flooring. Fig. VII is a detail cross section view, showing the metal tongue and the method of tonguing and grooving between the finished squares. Fig. VIII is a modified assembling ot' planks or boards and veneers showing a more complex form of my invention, in which special designs are produced. Fig. IX is a detail view of this complex structure sliced off lengthwise the grain with veneers applied to the sides of the sliced oit section, and the strip of blocks cut from the end thereof. Fig. X shows a detail section of the fioorng in this more complex form, showing the way in which the tongues and grooves are there formed.

In the drawings, similar numerals of reference refer to similar parts throughouitl the several views.

In Fig. I, I show a general View of a section of oor as formed according to my invention, the section there shown being made up of four complete squares. These squares are made up of blocks in suoli form that the ends of the grain of the wood are exposed to view and wear and warping and distortion is avoided. I accomplish this by forming the wood into strips made up of a series of blocks 2, and half blocks 8, see particularly Fig. I, glued or joined together. This is accomplished by piling a number of boards or planks 5-5 and a hoard or plank G of halt the thickness on top of each other and forming glued joints between the same. The board of halt the thickness may be either at the top or bottom. lVhen this is done in the simplest form of my invention, I cut ott a slice with a cross cut saw on the line 7, producing blocks like those appearing in Fig. III, and rip sawing on the lines S, see Fig. III, forming the same into a series of strips as seen in Fig. IV. lVhen these strips are thus formed, I form dovetailed tongues and grooves on the opposite'sides thereof, see particularly Fig. V, on a'Linderman dovetailing machine, the said dovetailed tongue 9 being tapered and the corresponding dovetail groove 10 being similarly formed and tapered on the opposite side. I .reverse the position of each alternate strip of block so that in adjacent strips the half blocks 3 will be at opposite ends of the strips and the joints between the blocks will be broken between the adjacent si ri s. This disposes the blocks so that the ten encies of the blocks to warp react the one against the other, thus insuring a tlateven tioor. Around the outside of a square or block that is thus assembled, I insert a' metal tongue 4I in a suitable narrow groove 4', which joins these sections together. The relation ot these parts and their grooving is indicated in Figs. VI and VII. j

In the structures of Figs. VIII, IX and X, I show the method otproducing fancy designs by variegated colors of the wood. In joining the lumber for this complex form, I intersperse layers of veneer these blocks I slice again by .3', as seen in Fig. VIII. I then slice the same lengthwise, as indicated in Fig. VIII, and on the tace of these slabs I aply an additional layer of veneer'l 13, see Fig'. IX. I then cross cut the `strips of blocks from the ends of the slab. The layer of veneer 13 is applied jon the side of the block on which the dovetailed groove 15 of the stri will be formed. A dovetailed tongueli 1s formed on the opposite side of the block onwhich there is no`veneer', and the groove 15 is of such depth as to reach through the veneer into the block beyond.`

The relation of these parts appears very clearly `in Fig. X. When the structure is assembled, it will be observed that the parts are very securely retained together by the dovetailed tongue and groove structure, and that all joints are broken and each of the smaller blocks is outlined by the material, the veneer, which may be of different color or character, producing a very pleasing effeet in the completed design, where the parts are firmly locked as Well as glued together. In either Astyle of Hoor, it is probably best to out the built-up timber lengthwise into slabs in the first instance.

. It is best to form this iiooring into composite squares to be assembled together.

blocks with the grain vertical and with the ,end grain exposed, the said blocks being The same, however, need not be put into this form, but the work of laying the same is greatly facilitated thereby.

From the description I have given, it will be observed that this flooring is capable of very great variations in designs, the same producing a very etfectivetloor in which all parts are securely joined. It will be possible to utilize waste ieces 7for this purpose, although the pro uction of the flooring is so economical that any ,lumber can be very readily and protably used. The availability of the invention, however, for utilizing waste pieces is very apparent because the end grain is utilized, and is of a good deal of advantage where the plant is engaged in a manufacture which occasions considerable waste.

Having thus described my invention,

what I claim as new and desire to secure by Letters Patent is:

1. YA floor construction made up of wood blocks with the grain vertical, and with the end grain ex osed, the said blocks being disposed and joined together in strips with layers of veneer therebetween, the

strips being coupl'd together by tapered blocks with the gra-in vertical and with the end grain exposed, the said blocks being disposed 'and joined together in stripswith layers of veneer therebetween, the Strips being coupled together by dovetailed longitudinal tongue and groove joints, and with a layer of veneer on the grooved side of the strips through which said groove is formed and which is divided thereby, the joints between the blocks on the adjacent strips being broken to join the parts se' curely and overcome distortion, as specified. 3. A` floor construction made up of wood disposed and joined together in strips, the strips being coupled together by tapered dovetailed longitudinal tongue`and groove joints, the joints between the blocks on the ladjacent strips being broken to join the parts securely and overcome distortion, the position of the blocks being retainedvby the wedging of the tapering o the dovetail, as

specified.

In witness whereof, .I have hereunto set Vmy hand and seal in the presence of two witnesses.
