' IMPROVEMENT IN STONE PVEMENTS.

Specification forming part of Letters Patent No. 177,859, dated May 23, 1876 application filed 4 December 4, 1875. l

To all whom it may concern Be it known that I, ARTHUR MAGINNIS, of Forks Station, Monroe county, Pennsylvania, have invented certain Improvements in Street-Pavements, of which the following is a specification:-

The object of my invent-ion is to construct a cheap and durable street pavement or roadway, and thisobject I attain in the manner which I will now proceed to describe,.refer ence being had to the accompanying drawing, in which Figure l is a vertical section of my improved pavement, and Fig. 2 a plan view of a 'port-ion of the same.

The road-bed or body of the pavement n consists ot' a'series of arches, each composed of a number 4ot' oblong blocks, of stone, hewn into proper shape for forming the arch, a key-stone, b, locking the latter in the usual manner. The arches abut at the ends `'against longitudinal blocks B of stone, in one corner of each of which is formed a recess adapted to the end stones ofthe arches.

The stones of the adjacent arches are s o arranged as to break joints, (see Fig. 2,) so that each arch is seltsnpporting and entirely independent of those on either side. The roadbed has the usuial broken stone and gravel foundation, and, if desired, a thin wall Vof ne gravel may intervene between the adjacent arches, but the stones which compose an arch should abut directly against each other, so as toform in effect a continuous arch. As long as the end blocks of this arch maintain their proper vertical position, the intervening blocks are prevented from sinking, and as the endblocks are. supported vertically by the abutment-blocks B, into the recessed corners of which they t, itfollows that the disintegration of the pavement is prevented, and a road-bed is produced which pressure from the top will only render more'compact and solid. Considering its durability and general advantages, the above-described pavement can be made at a very slight cost, the only important item of expense being the hewn abutment-blocks B-the blocks a being made from the refuse and dbris of quarries, and being rapidly shaped by means of circular saws.

The curb-stones d may be either separate from the abutment-blocks, as shown at the left-hand side of Fig. 1, or may form part of the same, as shown at the right-hand side of said figure, the latter plan being preferable on account of its solidity and the evenness of the curb in respect to the gutter, which it in-V sures.

I claim as my inventionl. A street pavement or roadway in which a series of arches, 'composed ofA hewn blocks a and key-stones b, are combined with each other and with longitudinal abutment-block B, recessed at the corners, so as to ai'ord a.

vertical support for the end blocks of the arch, I as and for the purpose set forth.

2. The abutment-block B, having a vertical projection, d, at one side, as and for the purpose set forth.

In testimony whereof I have signed my 'name to this specication in the presence of two subscribin g witnesses.

ARTHUR MAGINN IS.
