IMPROv-ED WOODEN PAVEMENT.

The Schedule` referred to :ln these Lett/ers Patent and making partici"l the same.

m Y l horizontally, two wooden strips,

To all whom it concern Be it known that I, DUNCAN MOKENziE. ofBrooklyn, in the county of Kings, and State of New York, have invented a new and useful Improvement in Wooden Pavements; and that the following description, taken in connection with the accompanying drawings, here inafter referred to, forms a full and exact specification of the same, wherein I have set forth the nature and principles of my said improvement, by which my inven-` have secured to me by Letters Patent.l

This invention relates to a new and useful improvementin wooden pavements of that class which are constru'cted of blocks, laid with the grain in a vertical posiallowed between the rows to receive sand and serve 'as a foot-hold for horses.

The invention consists in connecting the rows of of dovetail wooden strips attached to the sides of the blocks, and arranged in such a manner that when the pavement is laid it will be retained in proper position, or at the proper level, the several blocks sustaining each other throughout the entire length of the pavemen In the accompanying sheet of drawings- Figure 1 is a plan or top view of my invention.

-Figure 2, an end view of the same. Similar letters of reference in each of the ligures indicate corresponding parts.

A represents the blocks o ment is constructed. j

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.

Thesev blocks are set with the grain'of the wood iu an upright position, as shownv clearly in lig. 2, and to one side of each block there is attached, horizontally, by nails or otherwise,.a wooden strip, B, having bevelled or dovetail upper and4 lower surfaces, as shown in g. 2. e To the other side of the blocks there are attached,

wood of which the pave- G C, a space being allowed'between them, and the inner edges of these strips are bevelled, or of dovetail form, corresponding to the upper and lower surfaces of thestrips B, the space Ibetween the strips C C being of such a width as to receive the strips B, as shown clearly in iig. 2.

By'this arrangement it will be seen that the blocks A, when fitted together and laid for a pavement, will be in parallel rows, and connected together by dovetail/fasteniugs or locks, the blocks being laid so as to break joints, as it is commonly termed. (See fig. l.) rlhe .upper strips() are a short distance below the uppersnrfaces of the blocks A, so as to leave a space to receive sand, the blocks,

ered or dipped iu coal-tar, and the top of the pavement covered with a coat of said tar, and thespaeesbetWeeu the blocks then filled with sand.

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

I would remark that, instead ofthe double dovetail arrangement, as above described, a single dovetal may be employed; that is to say, the upper strips C may be dispensed with.

I find, in practice, that the single dovetail arrangef ment will answer' equally as good'a purpose as the .double one.

I do not claim broadly the use ofthe dovetail strips for securing wooden paving-blocks together, fas I am aware that this has been done before; but,

What I do claim as new, and desire to secure by Let ters Patent, is-

The wooden pavement, constructed, as described, of the blocks'A, secured together bymeans of the bevelled strips attached to the opposite sides of said blocks, so as to form either a single or double dovetail or lock, substantially as Vherein set forth.
