IMPROVEMENT IN. WOODEN-BLOCK PAVEMENTS.

1 v a I l The Schedule referred to hi these Letters Patent and piaking part of the same To all whom it may concern":

Be it known that I, Armxkxnnn Tanniinxay, of

Neuilly-sur-Seine, near Paris, F1ance, have invented a new and useful Improvement in \Vooden Pavement;

and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same.

This invention relates to the manufacture and application of mineralized wood blocks or slabs for paving purposes.

The invention comprises First, mineralizing' the wood paving-blocks.

Second, an improved concrete.

Third, an improved water-proof coating.

Fourth, an improved adhesive mastic.

Fifth, an improved'mineral glue, and

Sixth, an improved solid glue.

The paving-blocks are made of pine"; beech, or other suitable wood, and of suitable size. The blocks are cut a'crossgthe grain of the wood at an angle of about forty-five degrees. The blocks are then 'mineralized or. petrified in the manner hereinafter described, and, when they have become thereby solidified, I cover the lower half of each block with a water-proof coating,

which is covered with coarse sand. I am thereby enabled to fix these wood blocks as readily as those made of stone, and, in -this condition, they may be transported from place to place.

I prepare the ground to be paved \viththc im proved blocks by leveling and rolling, and then applying a layer of compressed concrete, of about two and a-half inches, for yards, stabling, or footways, and of about our inches for roads, according to the form to be given for the'same. By means of this concrete, I prevent thedamp rising from the soil, and form a very 'firm foundation'for the paving This being done, I lay down the blocks in the following manner:

The blocks are placed in rows across'the part to be paved, leaving a space of about three-eighths of an inch all around eachblock for an adhesive mastic to be introducedfornniting the blocks, or theymay be laid without mastic when used for paving courtyards and similar purposes. i

' For paving streets or roads, the blocks are to be placed in an inclined position, in rows, across the street, with a'space of about three-cight-hs of an inch between each block for the introduction of the adhesive'mastic or concrete before mentioned. In this mannera uniform surface may be obtained, of suificient firmness foralll purposes. In order to obtain a firm footing for horses, and prevent slipping, the blocks I are beveled ofi on top. v

For sidewalks, thefplocks are cut at an angle of forty five degrees andare united in squares by means. of mineral glue, for-resisting heat and moisture.

The blocks or slabs used for paving the interior of a Hydrocarburet of resin, part-s 40 Boiled linseed oil, containing litharge, parts. Pure wood tar, parts Naphthaline, parts 10 Pulverized plumbago, parts 7 10 Total parts 1-00 These materials are mixed together in an iron vessel, and then boiled. The blocks are then inserted in the liquid mass, and placed upon an'uon grating about two inches above the bottom of the vessel, and, after being treated. for a sufficient length of time, the blocks becomemineralized, and are then removed and placed in a drying apparatus for the purpose of hardening.

The concrete, before mentioned, is composed of Coarse river sand, parts Lime from gas-works, part-s 20 Hydraulic lime, parts 10 Pnlverized brick, parts 1 10 Dried and pulverized clay, parts 15 'lotul parts r.

These products are placed in an ordinary mortar mixing apparatus, and ground up, triturated, and

mixed together, after which the resulting compound of concrete is applied on the ground in squares of about a yard at a time, and well rammed and rolled,

so as to form a firm and impervious foundation.

The improved water-proofcoating, before mentioned, is composed oi' Goal-tar, parts 45 Resinous pitch, parts 7 1O Baked clay, parts 25 Pulverized lime, parts. 5

Plumbago, parts. 5

Sand, parts l 10 Total parts 100 These materials are placed in an iron vessel, and boiled andstirred until perfectly homogeneous.

The improved adhesive mastic, before mentioned, is composed of i Pitch from peat, parts. 40 Yellow galipot, parts 15 Whiting, parts 25 Pnlvcrized pumice-stone, part-s 10 Oxide of manganese, parts 10 Total parts H) The compound is prepared the same as that last described.

The mineral glue, before mentioned, is

composed of-- Common brown pitch, parts 40 Yellow wax, parts 5 Stearine, parts .3 10 Linseed-oil, containing Litharge, parts l 15 Red oxide of copper, parts Common resin, parts Sulphuric acid, parts Total parts t 100 Common glue, parts 4 5 White galipot, parts 10 These products are prepared the same as thosetlast described.

Having thus described my invention,

I claim as new and desire to secure by Letters Patent-- 1. The herein-described mineralizing compound for hardening wood, substantially as s'et'forth. 2. The composition for compressed concrete, prepared in the manner hereinbefore described, to be employed for forming a bed or base for the paving-blocks, as set forth.

3. The herein-described improved water-proof coating for the lower parts of the wooden blocks, prepared as set forth.

'4. The herein-described compound fdr an adhesive mastic for making the joints of the blocks'after placing them in position, as set forth.

5. The improved mineral glue for uniting the wooden blocks or slabs, as described.

6. The improved solid glue, prepared as and for the purposes described.
