` IMPRO'VEMENT IN WOOD PAVEMENTS.

Specification formin g part of Letters Patent N o. 171,619, dated December 28, 1875; application filed October 23, 1875.

To all wliom it may concern:

,Be it khown that I, SAMUEL HoUsToN, of the city and county of St. Louis and State of Missouri,.have invented a new and useful Iin-.

provement in Pavement, which improve'ment is fully set forth in the following speciiication, reference being'had to the accompanying drawings.

My improvement consists in a pavelnent which is formed of blocks of any description of timber, beveled at their sides at the upper portion. The blocks are grooved horizontally'at the sides, to admit the edges of the longitudinal and lateral frame-work bars, by which the blocks are held in their relative vertical position.

In the drawings, Figure 1 is a perspective view of a small section of pavement. Fig. 2 is a side view of a block. Fig. 31 is an end view of a block.

The blocks niay be of any suitable dimensions, and are preferably laid with the grain running vertically, as is usual With wooden pavements.

On the ends of the blocks A are rectangular grooves B, extendin g horizontally from side to side, and at the sides are similar grooves O,

extending from end to end. The grooves B' grooves B and O the sides are beveled upward,

as shown at a, so as to form angular spaces between the upper portions of the blocks, for the reception of asphalt, gravel, and pitch, or any similar material, which Would tend to fix the blocks more firmly in position or render the pavement less pervious to moisture.

In constructing the pavement, the blocks may be placed in a row across the'street, and the ends of the frame-bars D being held between the blocks, said bars extend horizontally and at right angles from the roW of blocks. is placed -in position, and the edges driven into the grooves O. Another transverse row of blocks may then be put inposition, and another line of bars E, and so on, the blocks fitting tightly together at their bottoms, and the bars D E being completely enveloped in the grooves B O. The asphalt or other material is then forced into the angular spaces F.

It will be seen that even before the additioir of the alphalt the locking-bars D E will efto a number of others, and also the distortion.

of the timber.

I claim aslmy invention- 4 The blocks A, fitting firmly together for some distance up ward from the bottom, and beveled from that point upward, to form, when placed together, a recess transverse to the street, for the reception of cement, and to afford a hold for'the feet ot' horses, in combination with the frame, consisting of longitudinal and transverse bars let into the sides of the blocks so i deeply as to allow the blocks to stand closely together, substantially as set forth.
