ALBERT V. SAMMIS, OF HUNTINGTON, NEW YORK.

PAVING-BLOCK.

Specfication of Letters Patent.

Application filed July 19, 1913. Serial No. 779,946.

To aZZ 'whom it may concem:

Be it known that I, ALBERT V. SAMMIS, a citizen of the United States, and resident of Huntington, county of Sufiolk, and State of New York, have invented certain new and useful Improvements in Paving-Blocks, of which the following is a specification.

The main Object of this invention is to provide an artificial or molcled paving block for use in making roadways and the like, and of such Construction and character that it may be laid on a hard dirt foundation without the necessity of first laying a concrete or other artificial foundation.

Another Object of the invention is to so construct the paving block that it will be held against .individual vertical displacement, each block being firmly locked to all of the abutting and contacting blocks. As these blocks are laid to break joints each block will be interlocked with six adjoining and abutting blocks so that they will each be supported by the surrounding blocks, and a downward strain brought on any one block will be transmittecl and distributed throughout alarge number of interlocked blocks.

Another Object of the invention is to so construct the block that it may be shifted or turned end for end, side for side and bottom for top. The advantage of this is that in laying a pavement, ro-adway, or even forming a wall with the blocks, theworkman may use the blocks as he finds them. It will not be necessary for him' to turn them about or to reverse them in order to bring them into proper interlocking relation to the blocks already set. As these blocks are of considerable size and weight it is manifest that by providing a block which may be brought into proper relation with the blocks already set or laid withouta preliminary manipulation the blocks may;

be laid with much less labor than would be necessary if the blocks had to be specially fitted and adjusted into position,

Other important Objects and advantages of the invention will appear hereinafter.

In the drawing, Figure 1 isa plan view of a series of blocks laid together; Fig. 2 a Vertical sectional View substantially on the line II-II of Fig. 1; Fig. 3 a similar view substantially on line III III of Fig. 1; Fig. 4 a plan view of a single block; Fig. 5

especially for paving roadways but which,

of course, may be used for walls or other purposes. The block is formed with upper and lower portions 2 and 3 and with areentral enlarged portion 4. Between the end portions and the central enlarged portions are formed grooves 5 which extend entirely around the block, said grooves forming, When the blocks are assembled, channels for the reception of water-proofing and sealing material, as shown clearly in Fig, 2. When the blocks are assembled channels are formed between the adjoining reduced portions 2 and 4: of the blocks, said channels being also adapted to receive sealing and water-proofing material.

.The blocks are rectangular in cross section and are formed with the long sides G and with the short ends 7. Each end of the block is formed with two outwardly extending pyramidal extensions or projections 8 and the two correspondingly shaped recesses 9. .The projections are arranged diagonally opposite each other on the end of the block and the recesses are correspondingly 'arrangedL The recesses and projections on one'end of the block are reversed in position with respect to the recesses and projections on the other end of the block so that a line passing through the block from the center of one pro-jection would intersect the center of a recess on the other end 'of the block. 3 and 6 of the drawing. By means of this arrangement of recesses and projectio-ns the blocks may be fitted together end for end without regard to which surface is uppermost so that the operator so assembling the blocks takes them as he finds them and This is shown very clearly in Figs. o

brings them together without preliminary blocks. Each group of interlocking elements consists of two outwardly extending pyramidal projections 12 and two similarly shaped recesses 13 in the block. "he projections are arranged diagonally opposite each other and the recesses are similarly arranged with respect to each other. The projections on one side of the block are arranged directly opposite recesses on the opposite side of the block, as shown clearly in Fig. 2 of the drawing. By this arrangement of interlocking elements in groups on the long sides of the blocks the workman in laying the blocks may assemble them as he finds them without the necessity of turning said blocks end for end or of reversing them or turning them over in order to bring the proper interlocking elements together.

The upper and lower inclined sides of the projections and recesses form cams or wedges which tend to throw the blocks laterally or outwardly from each other when a. downward strain is brought thereon. This downward strain, therefore, is converted into an outward or lateral thrust which serves to bind the blocks together in an arch-like Structure. By constructing the blocks with the interlocking projections and recesses of the shape shown they are self-sustaining and cannot be Vertically displaced by a depressing strain.

It is manifest that if desired the groups of interlocking elements on the ends of the blocks may be dispensed with. It is also manifest that for some purposes the groups of elements on the sides of the block may also be dispensed with. It is also manifest that if square blocks are to be used in the form of tiles only one group of interlocking elements need be placed on each side of the block. In this Construction, however, the blocks could not be laid to break joints.

lVhen the blocks are shapecl as shown in. the drawings they are laid to break joints. In this arrangement each block is interlocked on each of its sides with two abutting blocks; and, of course, its ends are interlocked with abutting blocks, as shown clearly in Fig. l of the drawing.

1. A paving block formed with a group of intcrlocking elements on each of two opposite Vertical faces, the group of elements on one face being directly opposite 'the group of elements on the other face, each group of elements consisting of two outwardly extending projections diagonally arranged with respect to each other and two inwardly extending recesses correspondingly arranged with respect to each other, the projections on one face of the block being directly opposite the recesses on the other face of the block.

2. A paving block formed with reduced upper and lower portions and an enlarged middle or central portion, a group of interlocking elements on each of two opposite Vertical faces of the enlarged portion of the block, the group of elements on one face being directly opposite the group of elements on the other face, each group of elements consisting of two outwardly extcnding projections diagonally arranged with respect to each other and two inwardly extending recesses correspondingly arranged with respect to each other, the projections on one face of the block being directly opposite the recesses on the other face of the block.

3. A paving block formed with reduced upper and lower portions and an enlarged middle or central portion, a groove extending around the block at the junction of the reduced portions with the enlarged portion, a group of interlocking elements on each of two opposite Vertical faces of the enlargecl portion of the block, the group of elements on one face being directly opposite the .group of elements on the other face, each group of elements consisting of two outwardly eXtending projections diagonally arranged with respect to each other and two inwardly extending recesses correspondingly arranged with respect to each other, the projections on one face of the block being directly opposite the recesses on the other face e of the block.

t. A rectangular paving block formed with two groups of interlocking elements on each of two opposite Vertical faces, said groups of elements being arranged equal distances from the ends of the block, the groups of elements on one face being directly opposite the groups of elements on the other face, each group of elements consisting of two outwardly extending projections diagonally arranged with respect to each other and two inwardly extending recesses correspondingly arranged with respect to each other, the projections on one face of the block being directly opposite the recesses on the other face of the block.
