To .all whom it may concern, y
Beit known that I, JAMES GLENN, of` Gincinnati,in the county of Hamiltonand State of Ohio, have inventedcertall new and useful Improvements in Iron Paving-Bricks, ofwhich Athe following is a specification.
My invention relates, to that class of paving `bricks or blocks which consist wholly or partly of artificial stone or concrete, and has for its object theb diminished cost of such paving vbricks or blocks, and an increased strength which case the inwardly-projecting flange is omitted. This shell is closed upon the top or table side and open at the bottom, and the eX- terior surface of the table may be roughened in any desired-design to furnish footholds. Into this shell I t strips of an elastic or yielding material-as pine, cypress, or cedar, or of felt or papervsaturated with tar-and then, the shell being inverted, or with open side up, I ll the space level to the'edges of the rim with a concrete of cement and sand, cement sand and screened gravel, articialstone, or asphalt and screened gravel, which, after its introduction into the shell, is allowed to harden naturally or under pressure; or in those localities where the extremes of temperature-'are not great, and the contraction of the shell upon the concrete filling is within the elastic limit ofthe cast-iron, I omit the strips of wood, felt, or paper, and construct the brick or block of the cast-iron shell and concrete lling alone.
In the accompanying drawings, in which similar letters of reference indicate similar parts, Figure lis a section of flagging constructed of my improved blocks containing the yielding strips. Fig. 2 is a perspective of one of the blocks inverted. Fig. 3 is a perspective of one of the blocks top up. Figs. 4 and 5 are sections of gutter 7 and curb stones constructed inthe manner of my improved pavingblock withthe yielding strips. y Fig. 6js an enlarged section of va nagging-block containing the yielding strips. Fig., 7 is a section ofsmall paving-blocks ofthe Belgian order. Fig. 8 is a section of a block of relative large superficial dimensions..V Fig, 9 is av section of `ordinary paving-blocks, and Fig. l() `is a section ofsuch blocks as I propose to` u seffor horse-railway y B is-thetilling, `which may beof concrete, of
'cement and;Vv sand, cement sand` :and screened gravel, or ofasphalt andscreenedgravel, or of what is known as articial stone, which illing is first proportioned and mixed in the usual manner, and then poured into the shell A, (the latter having iirst been inverted to receive the filling) and then allowed to harden naturally or under pressure.
C are the strips of wood or felt which are interposed between the cast-ironA of shell A and the bounding-surfaces of lling B,which strips, being of a yielding and slightly elastic material, permit the cast-iron shell A to. contract (in cold weather) upon the filling B without risk to the safety of either shell or filling. The flanges a?" hold the filling B irmly in the shell A and prevent it Vfrom loosening therefrom should the substrata upon which the block is l laid be undermined.
In small blocks for the Belgian style of paving the flanges a3 are preferably omitted and the rim of shell A tapered inwardly toward the bottom, as shown in Figs. 7 and 8, the spaces D between abutting blocks being lled with coarse sand, which prevents the edge of one block from chaiing upon the next should the bed upon which the blocks are laid be yielding or unstable. l
E in Figs. l and 10 are the customary cobble-stones for paving streets.
In constructing flag-blocks I propose, as
shown in Fig. 1, to make a center block, the
table a of which shall be ilat and of any desired design to roughen it for footholds, and two side blocks, A A,which are inclined from the level of street up to the level of the center roo block7 A. When thebloeks are to be of large dimensions-say twenty-four by forty two inches7 or of any snperlice greater than fourteen inches square-I prefer to make the shell A cellular7 as shown in Figs. 2 and S, in which event the ribs a are used.
By reference to Figs. i and 5 it is obvious that any desired form or size of blocks for guttering or curbing, or for any paving purposes whatsoever, may be constructed after my method with great facility.
In adapting the blocks to the use of horserailways the edges of shells Anext to the track are slightly beveled, as shown in Fig. 10,to permit of the easy lift of the wheels of vehicles from the train-rail to the normal level of the roadway.
The adaptation of my improved pavingblocks i'or horse-railways is peculiarly advantageous, as it prevents the present cha iing and cuttingofthepavement next to the rail-stringer by furnishing a hard unyielding surface, upon which the fretting of the wheels ot' vehicles will have no detrimental eii'ect.
In practice the casting ofthe shell A and introduction ol" filling lB and of strip C, when required, may all be accomplished at a factory for the purpose; or the shells A may be east at one. place and the iilling and strips introduced upon the spot where the block is to be used. The form of the cast-iron shell A is such as to give it great strength when loaded as a beam7 while the filling B, of concrete, furnishes the requisite weight and solidity required in paving-blocks.
Blocks constructed after my method will 4wear better than granite, and inthe fest and South can be had much cheaper than granite.
Referring to such a block as is shown in Fig. G, the width would be, measured upon the table a, about twenty-four inches, the depth about six inches, and the thickness of rim a and iange a or rib a? about one-quarter inch, although the dimensions willalways be proportioned to the trai'iie or loads which may come upon the block in use.
I am aware that paving-blocks of artificial stone7 of concrete, and oi' asphalt and sand or gravel are not novel, and these I do not claim.
Having described my inventioinwhat, I claim 1s- A paving brick or block consisting ofa eastiron shell, as A. and a concrete filling, as B, with yielding strips, as C, interposed between the castirou shell and concrete filling, constructed substantially in the manner and i'or the purpose described.
In testimony whereof Ihave signed my naine to ille foregoing specification in the presence of two subscribing witnesses.
JAMES M. GLENN.
