IMPROVEMENT IN WOOD-PAVEMENTS.

Specification forming part of Letters Patent No. 123,219, dated J annary 30, 1872.

To all whom it may concern:

Be it known that I, GEORGE A. BEIDLER, of Philadelphia, in the county of Philadelphia and in the State of Pennsylvania, have invented certain new and useful Improvements in \Vood Pavement and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying dr wing and to the letters of reference marked thereon making a part of this specification.

The nature of my invention consists in a wooden pavement composed of wedge-shaped blocks cut or sawed away at each end near the base to form a tenon and shoulder, and resting upon strips or scantlings laid lengthwise with the street, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure 1 is a perspective View of a portion of the pavement, and Fig. 2 is a perspective view of one individual block.

A A represent the wooden blocks, having their sides beveled so as to be wider at the base than at the top; or in other words, made wedgesha-ped. At each end, near the base, these blocks are cut or sawed away to form a tenon, a, with a shoulder, I), at each end. The blocks A A rest with their shoulders b I) upon strips or scantlin gs B B, which are laid parallel with each other and suitable distance apart to receivebetween themthe tenons cc of the blocks. These strips or scantlings run lengthwise with the street and not across the same. When the blocks break joints a central transverse groove must also be cut in the bottom of the block.

By this mode of laying the supporting-strips the pavement can be made with very little, if any, trouble to form the necessary curve of the street; and, when necessary to take up any part of the pavement for the laying or repairing of gas and water pipes, etc, it can be done very readily the whole length of the street, and only so much in width as is necessary to dig downone, two, or three rows of the blocks.

I may Burnetizc or otherwise prepare the blocks and the strips to preserve the wood. The spaces between the blocks are to be filled with gravel, sand, tar, or pitch, concrete, or any other suitable material.

I do not claim a wedgeshaped block; nor do I claim wedge-shaped blocks provided with grooves on their sides, through which strips are passed crosswise of the street for securing the blocks in place; but

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

The wedge-shaped block A cut or sawed away at each end near the base to form a tenon and shoulder, and resting upon the strips or scantlings B laid lengthwise with the street, substantially as and for the purposes herein set forth.

Intestimony that I claim the foregoing I have hereunto set my hand this 11th day of November, 1871.

GEO. A.- BEIDLER.
