IMPROVED WOODEN PAVEMENT.

' @te .shtult tuant t: it time ettet patent mit mating ont at tige time.

`TO ALL WHOM IT MAY ONQERN: Be it known that I, DUNCAN McKENzIE, of Brooklyn, in the county of I ings, and State of New York, have i invented a new and useful Improvement in Wooden Pavements; and I do hereby declare lthat the followingis a fall, clear, and exact description thereof, which will enable-those skilled in theart to make and use the same,

' 'reference being had to the accompanying drawings, forming part of this specification.

. This linventionV relates to avnew and'usef'ul improvement inwoorlenpavements, of thatclass which are constructed of blocks laid with the grain in a vertical position, and placed in parallel'rows, with a space or-rccess allowed between the rows to receive sand audserve as a foot-hold for horses.

The invention consists in connecting the rows of wooden blocks Vby means of dove-tail wooden strips- `attached to the sides of the blocks, and arranged insuch a manner that when the pavement islaid, it will be retained in proper position or at the proper level, the several blocks sustaining each other throughout the entire length of the pavement. v-

In the accompanying sheet of drawings-v Figure 1 is a plan or top view of'my invention.

Figurel, an end view of the same. i

Similar letters of reference indicate corresponding'parts.

A represents the blocks of wood'ot' which thcpaver'nent is constructed.

' Any suitable timber may be used, but spruce plank, from three to four inches thick, and cut into lengths,v

say, of eight inches, will probably be the most desirable.

.Thcseb'locks are set with the grain of the wood in an upright position, as shown clearlyjin iig. 2, and to o ne side of cach block there is attached horizontally, by nails'o'r otherwise, a wooden stripB, having bevelled or dove-,tail'upper and lower surfaces, as shown in fig. 2. l 4

'lo the other side of the blocks 'there are attached horizontally two wooden strips C C, a space being allowed bettveeni't'hem, and the innei` edges ot'v these strips are bevelled oro'tfdovc-tail form, corresponding to Vtheupper andlower surfaces of the strips B, the space between the strips G C being of such a width as to receive the strips B, as shown clearly in 2- l By this arrangement it will he seen that the blocks A, when fitted togetliel'ancl laidfor a pavement, will be in parallel rows, and connected together by dove-tail fastenings or locks, the blocks being laid so as to break joints, as it is commonly terined, (see tig. l.)

The upper strips C are a short distance below the upper surfaces of the blocks A, so as to leave a space to receive sand, the blocks, as they are laid, being-covercdor dipped in coal-tar, and thetop of the pavement covered with a coat of said tar, and the spaces between lthe blocks lthenlled with sand,

The blocks A may be laid on a concrete or plank foundation, the street, of course, being properly graded previous to laying the foundation.

4 IIdo not claim broadly the use of dove-tailed strips for securing wooden paving-blocks together, as I am aware that this has been done before; but

What I 'do claim as new, and desire to secure by Letters Patent, isl The wooden pavement, constructed, as described', of the blocks AIL, secured together by means of the bcvelled str-ips attached to the opposite sides of said blocks A, in the manner substantially as herein shown and described.
