PATENTED APR. 9', 199'? A TTORNBYS' or sinulzu liquid packing l6 to prevent Leahillc sockets and mating linuclilcs arc almfpre cral'ily coated with pitch or asphalt prcparatory to laying the same into thcivall, and after the wall is roniplctcd the interior face thereof is coated with a thin luyor of cenicnt, a quantity of the liquid ccnncntbcing poured into the pocket 16 upon the pitch or asphalt to form a closure for said pockct.

in order to reinforce and tank, suitable rods or bands 17 are disposed at spaced intervals on lhc cxtorior walls of rods 17 bear against exterior walls of the tank at the knuckles 7, so that when the tension of the bands or rods are regulated by adjusting the nuts 20 the knuckles will be forccd into engagement with the sockets, and

thereby cllectually prevent accidental dis-.

placement of the blocks.

By having portions of the bands spaced from the Wall in this manner it also permits expansion of the rcccssed ends of the blocks when the water in the [unit freezes, While by having the frce ends of the arms 18 hearing against the adjacent blocks szild arms are braced and' prevented from bending when the rods or bands are tightened.

if desired, a suitable door may be formed in the side Walls of the tank below-the auxiliary bottom by omitting one of the blocks or slaves, so that a Water-supply pipe may be extended upwardly between the Walls of the standard 9 and through the auxiliary bottom of the tank for supplying water to the latter.

In Fig. 6 of tho drawings there is illustrated a modified form of the invention in which the auxiliary bottom and central supnort or standard are .disposed with the blocks 5, beingerected on a foundation of cement, mortar, or other suitable material 3 l, which is subsequently coated with a layer of cement 22 or with alayer of pitch covered with cement.

In Figs. 7 to 10, inclusive, there is illus* trated a further i'nodification in which the blocks are arranged to form a culvert or arched structure. there are provided a, plurality of s )sccd columns or supports 23, preferably formed of substantially rectangular-shaped blocks 24, some of which are curved to form the arch or top of the culvert, as indicated at 25. The blocks 24 are rovided with alined longitudiholly-dispose channels or recesses 26, adapted to receive the adj acent ends of the blocks or stoves 5, as best shown in Figs. 7 and 8 of the drawin s, the blocks 5 in tnis case being oblong-in rape and disposed one about the other throughout the height of the arch or culvert. The exterior faces of the blocks In tl is form of the device forming the supports 23 are-also provided with grooves or channels 27, in which are scatcd reinforcing-bars 28, said bars being conncctcd to similar bars 29, engaging the interior faccsof the blocks by clamping-rods 3t), passing through plates or Washers 3t), and seated in transverse grooves 31, formed :in the abutting faces of the blocks 24, as shown. strengthen tho 1 in order to reinforce and strengthen thc side walls of thc culvert, suitable tic-rods I o2 arc thrczulcd through openings Si) in the blocks 2 1- and clamped in position by nuts 34. A layer of mortar or cement 35 is placed within the channels 26 to protect the bars 28 from the action of the elements, and the inner faces of thc blocks 5 are also preferably coated with a thin layer of liquid cement, in the manner before described. It will of course be understood that in constructing thev culvert tho concuved and convexed faces of thebloclzs or staves 5 may be coated with pitch or asphalt in order to form a more perfect union. between the several blocks, and thereby prevent leakage.

lzlaving thus described the invention, What is claimed is 1. In building construction, a plurality of blocks each having one longitudinal edge thereof convex and its opposite edge concave for the reception of the convex portion of an adjacent block, said blocks being laid in circular form and arranged in superposed courses, and a binding-rod engaging the side Walls of the several blocks at convex ends thereof and spaced laterally from the conr00 caved ends of the blocks.

2. In building construction, a plurality of blocks each having one longitudinal edge thereof convcx and its opposite edge concave for the reception of the convex portion of an 105 adjacent block, said blocks being laid in circular form and arranged in superposed courses, at binding-rod engaging the side alls of the several blocks at the convex ends thereof and spaced laterally from the con- Ixo caved ends of said blocks, and means for adjusting the tension of the rod to thereby force the convex end of one block to its seat in the concavity of the mating block.

3. In building construction, a plurality of 1 15 blocks each having one longitudinal edge thereof convex and its opposite edge concave for the reception of the convex portion of an adjacent block said bloclr being laid in circular form and disposed in superposed courses, clips having perforated angular (lisposed arms the free ends of which bear against the blocks, threaded binding-rods passing through the perforation in the arms and engaging the Walls of the blocks at the 12 5 convex ends thereof said rods being spaced laterally from the concaved ends of the blocks, and nuts threaded on the binding Wires and adapted to engage the angular arms for adjusting the tension of said rods.

, blocks each having seems courses at one en of the wall, a central sup port ior'the diaphragm, and binding-rods emhracin the wall and bearing against the walls of t e blocks at the convex ends thereof,

vsaid rods being s aced laterally from the I concaved ends of t e blocks.

5. In building construction, a plurality of blocks each having one longitudinal edge thereof convex and lts opposite edge concave for the reception'of the convex portion of an adjacent block, said block .being laid in superposed courses to form a circular wall, a diaphragm interposed between adjacent courses at one end of the wall and havin a plurality of reinforcing-rods embed ed therein and extending within the wall, a

liquid coating for the interior surface of the. wall, and binding-rods embracing the extenor surface of the wall and bearlng against the wallsof the blocks at the convex ends thereof. i v i 6. In building construction, a plurality of blocks each having one longitudinal edge gig thereof convex and its opposite edge 'concave for the rece tion of the convex ortion of an adjacent h ock, said blocks eing laid in superposed courses to form .a circular wall ainl. havin their mating edges covered with Waterproo material, a diaphragm interposed ower between the adjacent courses at the end of the Wall and provided With an annular shoulder spaced from said wall to form a pocket adapted to receive a plastic material,

and a plurality of spaced binding-rods embracing the exterior'of the wall and hearing against the walls of the blocks at'the convex ends thereof.

In testimony that I claim the foregoing as my own I have hereto atfixed my signature in the presence of two witnesses.
