PARQUET-FLOOR.

SPECIFICATION forming part of Letters Patent No. 256,306, dated April 11, 1882.

Application tiled December 9,1881. (No model.) Y

To all whom 'it may concern: Y l

Be it known that I, ROBERT WILH. ELTZ- NER, ot' the city, county, `and State of New York, haveinvent-ed 'certain new and useful Imof metallic cleats, which are driven into the adjoining edges of the blocks in such amanner that a rigid connection of the blocks Within each exterior fastening-band is obtained and provenients in Manufacturing Par'quet-Floors,.-that they are tirml y unitedv without the use of of which the following is a specification.

This invention relates toan improved method of manufacturing parquet-doors from wood without the use of glue or Lother binding material; and the invention 'consists of a number of properly-selected pieces of wood of different colors and suitable length, which are united together by exterior metallic bands' and transverse fastening strips or railsafhso that when the pieces have been so connected they can be separated, by transversely sawing through them,into as many panels as bannds have been used. The panels may be used for doors of rooms as well as for ogripgwolialls and pavements of passage-ways.

In the accompanying drawings, Figures 1,2, and 3 represent side views of different blocks from which thejijningglus for parquet-floors are obtained, the dotted lines represen ting the lines of sawing off the panels. Figs. 4t, 5, and 6 are plan views of dierent panels. Figs. 7, 8, and 9 are side views ofthe individual panels shown in Figs. L, iaud Figs. l0, 1l, and 12 show Y the applicati'mii the same principle to stone.

Similar letters ot' reference indicaievcorresponding parts.

According to the design in which the par quet-loor is desired tobe laid, there are formed anumber of blocks of square cross-section from longitudinal pieces o ot' wood of square crosssectmiitable length, which pieces differ in eolor according to the design. AThese longitudinal pieces of wood a are laid up together to form a composite log and united eX- teriorly by means t' metallic bands b, which are fastened parallel to each other around the composite log formed 'bythejpieces u at intervals of equal or varying width, according to the style of 'parquet-flooring to be produced.

Between the individual blocks or pieces a of the composite log are interposed in the plane ot' each exterior bandfb, and of the same width therewith, transverse metallic strips 1@which are nailed to the blocks, as shown clearly in Figui. The blocks or pieces c may also be connected transversely with each other by means are tilled up afterward by suitable material.

more exactly the strips have' been fitted into v the wood.

The thickness of the exterior bands,b, should be only one/halt' ofJ the thickness ot' the trans verse strips, sol as to obtain throughout the parquet-floor a unifpripwjdth of joint.

It" desired, the parquet-floor can be made perfectly waterland re proof byimpregnating the wood with pilqper cheinjcals. The panels can be placed upoiwfo'undations of `wood, cement, asphaltum, or other suitable material.

It is obvious that by a proper arrangement ot' colors a number of designs can be obtained, so that a very ornamental, durable, and cheap parquet-door is the result. a

, The same principle may also be applied to stone, only with this difference, that instead of exterior connecting-bands, galvanizedmetal frames have to be used, to which the crossstrips are rigidlysecured. In this case the open joints will be preferred, so as to give a better foothold. The panels are cut oft'vby a stone-sawing IOO I am aware that wood tiles have been obtained by being transversely sewed oi from composite logs the blocks or pieces of which have been glued together. I am also aware 5 that parquet-homing hns been made of sections which are connected to each other by mea-ns of tongues or grooves. To these features I lay no claim, ns I desire to avoid the use of glue and to make each panel or tile very zo strong and. compact for itself by the exterior band. and the laterall connection of the individual wooden pieces or blocks forming each panel. v

Having thus described ni'y invention, I claim 15 as new and desire to secure by Letters Patent-M ROBERT NILII ELTZNER.
