Specification of Bissued Letters-Patent. Reissued June 29 192() 'originll'lq'o. 1,2;008, dated October "28, 1917 Serial No. 2100;951, "filed May 31, 1916. Application for n reissue med semember 20, 1919. Serial No. 325,253.
To 'all whom it may concern:
Be it known that I, HAROLD S. WHEELER, a citizen of the United States, residing at V Tacoma, in the county of Pierce, State of Washington, have invented certain new and useful Improvements in Building and Paving Blocks, of which the following is a specification.
This invention relates to building blocks formed of plastic or cast material, such as clay or concrete. The *obg'jects of my invention are to provide an improved form '01? interlocking 'or keyed blocks, giving a new effect and result highly desirable in both wall and road paving construction.
When my improved block is used for wall building, the interlocking feature will efi'ectivelyhol'd the blocks-against displacement by a side thrust against the wall as will be apparent -from a study of the accompanying drawing, and the description herein-after given.
'And when my improved block is used for road building said interlocking feature will function to distribute the wheel-load vertically over-a larger surface of the base then the bearingsurface of the block to which the 'load'is applied, and which will carry the horizontal thrusts of the road-arch to the curbing; in which the ends are formed so as to facilitate the laying of straight or curved roadways. The blocks may be made either solid or hollow, and if made hollow, will drain the road effectively. The blocks can be used either as a complete pavement by themselves, or may have a concrete *or other base, or may be used as a basefor a different wearing surface. n
It will suiiice to illustrate the attainment of the neweifect and results referred to by showing the practical application of my new interlocking block for road building, since the wall construction-obtained by the use of the same block will be apparent by simply turning said drawin so that the supporting base will be relativey moved-into a plane, perpendicular to that of the horizontal road ase.
In the accompanying drawing, Figure 1 is a cross-section of a road pavem'ent fonned of my block;
Fig. 2 is a section showing that portion thereof adjacent the curbing;
Fig. 3 is a plan of a portion of such a road carried by the inclined surfaces '7 showing a straight and a curved portion therein; and
Fig. 4 is a perspective view showing the corrugated. form of my block.
Each block consists of two main parts, the broad head 1 and the narrower tongue 2. The tongue 2 extends from end to end of the head 1, along its center, and may convenientl'y be made substantially one fourth the width of the said head 1, though in blocks for some purposes the tongue is made only a little narrower from the head. The outer surfaces 3 and 4, respectively, of the head and tongue form the wearing or exposed surface of the structure and in general lie in parallel planes. The two ends 5 and 6 of the blocks are cut vertically but are preferably not parallel, theblock being shorter on i i one side than on the other,.so that the transverse joints between blocks are inclined at less than a right-angle to the line of the "the sides 7 and 8 make about five degrees with the vertical. The undercut surf-aces 9, adjacent the tongue and joining the side surfaces 7 and 8 on each side of the block, are not parallel with the wearing surfaces 3 and surfaces on the othersides of the block, re-
spectively. Thus, in the drawings, the surfaces 9 make an angle of about five degrees with the horizontal (toward the center of the surface 3) and about eighty degrees with the adjacent parallel sides 7 and '8. Thus it will be seen that each block is keyed with each adjacent block so that when the. wheel-load comes on the face 3 of the head 1 it is transmitted to the four inverted blocks in contact therewith through the undercut surfaces 9 and sirnultaneously tends to draw all said blocks together, while if the wheel-load comes on the face 4 of the tongue 2, it is and 8 to the ad acent blocks.
'4 but are equally inclined upward. so as to lie substantially at right-angles with the side v2, in which three longitudinal holes 10 e x tend from end to end of the block, through the head 1, and one similar inverted hole 11' is inlthe tongue-2, said holes being positioned so that the central hole 10 and the hole 11' are vertically in line and so that the side hole 10 of one block is vertically over the side hole 10 of the interlocked adjacent block, and so that the holes 10 and 11 in interlocked adj a cent blocks lie in the same horizontal planes. This arrangement of the holes 10 and 11 develops a horizontal intermediate thrust wall 12 throughout the entire structure, leading to the two sides thereofand midway between the two wearing surfaces 3 and 4; and'bearing webs 13 between the central hole 10 and each side hole 10." It will be noted that thewebs forming the sides 7 and 8 adjacent each other in the structure together are of the same size and vertically in line with the bearing web-13 above or be low the said joint, and that thewebs forming the adjacent undercut sides 9 of two blocks together are of the same size and horizontally in line with the intermediate thrust web 12. These holes 10 and ll all .connect together in adjacent blocks thus forming a set of continuous conduits running lengthwise of the roadway, and these conduits may, at suitable intervals, be connected to a cross drain below theirlevel in the usual way, thus effectively draining the roadway at all points in its -surface.
The surfaces '3 and 4; maybe flat, with a smooth finish, orroughened, ormay be slightly corrugated, as shown .in Fig. 4. When they are made corrugated they will be especially adapted for roads which are largely used by motor vehicles, since the will lie parallel with the roadway and wi l therefore resist skidding and will tend to keep the vehicle on a straight path. Such corrugations will-also give a larger bearing surface for pneumatic tired vehicles and will therefore tend to prolong the life ofthetires and of the blocks, and the under surfaces, be- 7 in also corrugated, will grip the base more e ectively.
Since the ends 5 and Gare cut at an angle to each other it isevident that when laying a straight roadway the blocks must be reversed so that the ends 5 of one block will contact with the end 5 of the next adjacent block and so that the ends 6 of two adjacent. blockswill contact with each other; and thatwhen laying a curved roadway they will ,all be laid with their short sides toward the center of the curve so that all the transverse edges will be substantially radial from said center, the end 5 of each block contacting with the edge 6 of the adjacent block.
,1 As obvious from an inspection of 2 of the drawing, the interlocking feature above described, functions equally as efiicientlyin the use of my blocks for wall and floor building, and such use is not only suggested but is clearly shown by merely turning said drawing on its side as above mentioned; and the same new: result whichis attained in the use of my block for road building, is also attained in the use of my block for wall building, andlike purposes.
In other words,rsupposing my blocks to have been built into a wall, it is obvious to any oneskilled in the art'of wall construction that'the wall so produced will-have maximum strength for load-carrying purposes even though the blocks be made hol low, that is, the voids as above described,
because all carrying webs will besubstan- -tially in vertical alinement. At the same time the wall will effectively resist any side thrust, for when pressure is brought to bear against the face 2 of the tongue of a block, a double wedge action will result, due to the inclined faces 7 of the head bearing on the inclined-faces 8 of the tongue; and likewise, inicase of a side thrust against the face 3 of the head of the block, the inclined surfaces 9 on the inner faces of the head of the block --adjacentthe tongue will tend to pull the block'above and the block below into closer relation instead of tending' to push. them outward. M j v Q Hence the interlocking resulting from the particular. construction of said bearing. faces renders it impossible to overturn any block in the wall without first displacing it and throwing it out of the line ofthe wall. In short, the blocks are not only effectively interlocked with each other, but any side 1. thrust'tendsto promote the interlocking re- -lation rather than-disturb it. Thisfeature is the most important result obtained by my improved block, and as mentioned, is present to the same degree whether said blocks A be used for building a wall or a paving for aroad. f
What I claim is: I I a 1. A paving block comprising a head, having a bearing surface; and a tongue, extending centrally from end to end of the head and narrower than said head; the faces of said head adjacent the tongue being inclined goward the central line of said bearing surace. J
tongue each being inclined from its outer edge toward the central line of the bearing surface of the head.
3. A paving block comprising a broad head having a bearing surface and a narrow tongue having an inverted bearing surface, and having a plurality of voids in the head and a single void in the tongue, the single void in the tongue being in corresponding inverted position to the voids in the head, whereby when adjacent blocks are placed in complementary positions the voids in the tongues aline with the voids in the heads to form an upper and a lower row of voids and whereby the contiguous horizontal thrust webs thus formed between said two rows of voids extend in arched alinement across the road.
