EDWARD HENNESSEY, or WASHINGTON-COUNTY;DISTRICT or COLUMBIA. 'rmm aant m 72,734, dated December 31, 1867.
IMPROVEMENT IN BRICKS F OR'CUBVED MASONRY-WORK.
TO ALL WHOM IT MAY CONCERN:
Be it known that I, EDWARD Hermes, of the county of Washington, and District of Columbia, have invented a new and improved Brick for Preventing Conduits, Shafts, or Curved Work in Masonry from Bursting or Collapsing; and I do hereby declare that .the following is a full and exact description thereof, reference being bad to the accompanying drawings, and to the figures and letters -ofreference marked thereon.
The nature of my invention consists in the form of bricks, stone, composition, or pieces of any material adapted to the construction of conduits, shafts, or curve-work in masonry, securing a greater amount of strength to resist hydrostatic pressure or other force from the inside or outside thereof; and for ordinary circular work in masonry, such as conduits or shafts, my bricks can be used without mortar or cement.
To enable others skilled in the art to make and use my invention, I will' proceed to describe its construe- I construct my conduits in the usual circular form, as shown atFigure 1 in the accompanying drawing, a being the large end of abrick, formed like a keystone, with corrugated edges; 6 the body, and c the small end thereof. See also it b c in full size outline drawing, Figure 7.) d, inside capacity of circular conduit, five feet in diameter. The dotted lines from the top to the centre show the direction of the serpentine li'nes forming the corrugated edges of the bricks. These edges hold the bricks together in such a manner that if a circle formed (as shown by fig. 1) upon a level plane with such shaped bricks, no one of them could be removed by pressure from the insidewithout removing a number'of theadjeining ones. The corrugated edges are formed by straight I lines across, and undulating-lines lengthwise of the bricks. (S ec'Figune 4:.) a, largecnd, 6, body, and c the small end, the hollows of oneside conforming to the rounds of the'other side of the same brick, that is, the corrugations correspond with each other, so that the bricks will fit into each other, as shown. by drawing, fig. 1.
Having thus described two surfaces corresponding with the edges of the bricks, I will now proceed to describe the other two sides, corresponding with the flat or broadest surface of the bricks. The sides are cor-v rugated by straight linesgrunning lengthwise of the. bricks, and undulating lines running crosswise. This is done by making a hollow or' concave, extending lengthwise along the centre of the'flat surface at each side of said hollow, the surface-rounds towards the edges of the bricks forming a double og'ee. This is done on both sides of the brickjust alike. (See full-size outline of end of brick a, fig. 7; also, a, fig. 2, and a, fig. 3, but a, fig. 4,-
and a, fig. 6, show the shape of the end before the ogee is made.) This ogee diminishes as it approaches the small end of the brick, making itscurved lines corresponding to sections of a cone, which leaves thesmall end ot'the brick thicker through the centre thauthe large end. (Seedottcd lines a c ata, fig. 7.) These dotted lines correspond with the outlines of c, fig. 7, so that if the edges of the brick were straight, as shown by Figure 3, it could not be forced outward from the centre of the arch'if placed as Sl10\vfl:l)y a, Figure 5, for-two reasons: first, because the inside end being thicker at-its narrowest point than the outside end is, -it could not come through a thinner aperture than its own thickness without displacing other bricks; secondly, when they are laid as in fig. 5, the hollow of brick a holds the rounds of two of the next tier, and the hbllows being narrowest at the small end, would clamp the two bricks on either side of it in such a manner that the rcsistanceagainst those four bricks would be equal to the force against a from the inside.
Fig. 5 shows a section of a conduit intended to resist hydrostatic pressure, and fig. 6 shows a section which would not. Figs. 5 and 6 show how they may be united.
I do not claim the known shape of keys as commonly used in arches, curves, encircles in ordinary masonry,
neither do I confine myself to any particular length, thickness, or width of bricks or blocks; aslthesc would be varied according to any required sine and nature of the work; but
What I do claim as my invention and desire to secureby Letters Patent, is
The bricks, made of stone or any material,- corrugated andtapering, as herein described, for conduits or I curved work, as in masonry, to prevent the bursting or collapsing thereof.
