l IMPROVED WOODEN PAVEMENT.

asm

TO ALL WHOMIT MAY CONCERN:

` Beit known that I, PHILIPPE KOCH, of the city and county of New Haven, in the State of Connecticut, have invented a new and useful Improvement in Blocks for Paving Streets, Roads, &c.; and I do hereby declare that the following is a full, clear, and exact description of the construction, character, and operation of, the same, reference being had 'tp the accompanying drawing, which makes part of this specification, which drawing is a perspective view of one complete block and a portion of an adjoining'one, showing the form of the upper surface and the manner of connectingrorjoining the blocks when set.

My improvement consists Vin making square or other rectangular blocks of wood ofsuitable length (with the grain of the wood) to suit the character of the streetor road, and of such horizontal dimensions as shall be found most convenient and serviceable in each case, and suitably bevelled upward and downward for a suitable distance from the ends, and to be set in the ground or sand, thes'ame as prepared'stones are, (as of the Belgian pavement, for example,) and the upper surface cut to' a suitable depth into squares or rectangular forms, so that the spaces may be filled with dirt to make it easy and safe for horsesto travel upon, as they will not slip.

I make the block for paving of Whiteoak, or any other suitable wood, sawed, split, or cut into `square blocks, as represented in the drawing, of suitable dimensions to be convenient for setting or laying the pavement, say from six to twelve inches square, in the horizontal directionsior across the grain) and from eight to ten inches in the vertical line, (in the direction of the grain,) according to theicharactcr of the ground or use to be made of the street or road; and I cut or divide the upper surface of each block into small squares, say from one to two inchessquare, as represented at A A, 85o., cutting the spaces bothY ways from one-half to three fourths of an inch in width, as represented at Z1 and c, and from one to two inches in depth, as represented at i d and c, which maybe readily done by a plou'ghing or grooving machine, by causing the blocks vto passV through in any convenient manner to suit th'e'design of the work; and I bevel the upper end, on all sides, of each block, as represented at g, h, and 7c, so that where two blocks, as B and C, come together, they will leave a. space at the top, as represented at g g-g, of about thel same dimensions at the extreme top as the spaces orlch'annelswhich.

are cut in the blocks; and I also bevel the block, on all sides, at the bottom or lower` end, as represented at D, E, F, and G, so that they maybe iiorced into the ground more readily, and also it and set more steadily in their proper positions.l 4

Having made the bloclgs, as before described, I prepare the-streetl or road in the same way as for paving with prepared stones, and then set lthe blocks in the ground or sand side by side, as shown at lB and C, and set them down the same as stone blocks, and then I'ill4 the channels or spaces 6, c, d, e with sand in tlie nsualway, so that if there should be any looseness p between the blocks (as B and C) the sahd 'will run down the inclined sides, asatg g g, between the blocks so as to till the spaces perfectly solid, so as to bind and always keepythem4 steady and firm. By the action of the feet of the horses and whe'els of the carriages, the corners and edges of the small square surfaces will beforced or bruised olf and broomed down so as to confine the sand in the grooves, which will 'give the pavement a general evenness, with a slight waving, so as to bel easy to the horses feet, and Will not be slippery. Instead of ploughing the grooves parallel with the sides of the block, they may be cut diagonally, and the blocks may be made as elongated rectangles or hexagons, but .I prefer the squarev I amaware thatlwooden blocks set in iron frames have been used in England, as describedin Newtons Journal, first series, volume 9, pages 197 to 202; also, that Stephen Cary obtained a patent, dated February 8,.,

1841, for using large quadrangular blocks with theirvertical sides cut alternately concave and convex, and,

although the blocks were so bevellcd upward as to leave a space around them, yet each block 'was left smooth;

on the whole of its upper surface, which caused horses to slip so badly' that it was discarded; also, that Samuel.' Nicolson obtained a patent, dated August 8, 1854s, for the use of small-,blocks set alternately with blocks of` about one-half their length, so as to form recesses to b e lled with gravel and tar, or otherrcemento cement the gravel, and also the small wooden blocks, together, or (he says) the blocks may be secured together byhwooden pins,and he uScsta-rred paper, boards, or lime mortar 'to prepare the foundation on'which `his pavement is to rest. This (if the small blocks were not irregularly forced into the ground so as to destroy the evenness ofthe road) would make the pavement so .cstly as to forbid its use.4 Iy therefore do not 'claim either of these methods'v as my invention, nor do I desire 'to use either; but what I'claim as my invention, and desire to secure byLetters Patent, is-- The construction and arrangcrnentvot' wooden paving-blocks nthe manner and for the purpose hereinv described and set forth.

PHILIPPE KOCH.
