To all fwioml t may concern: x

Be it known that I, Ti-rnononn citizen of `the United States, Aresiding 1n Floral Park, Long VIsland, New York, have 5 invented certain new and useful Improve ments in Concrete Construction,A of which the following is the specification.

My inventionrelates to the elimination in concrete construction ofthe use of a tempoand Vreinforcing being combined into a single structural,l member w-hichperforms the functions of both'. This is accomplished in such a manner that the concrete may still be poured as in the-'case of the previous type of construction in which temporary molds were utilized. `lnmy improved construction I use as the combined moldandreinforcement a reticulated structure, preferably in the foim of a coarse wire .2O screen, 'the interstices of which are suffi,-`

ciently large to perin't the finer grade of concrete to pass through but obstructing the passage of the coarser concrete therethrough and thereby' embed the mold, thus converting it into a permanent'reinforcement.

n the construction of the concrete structure of the present invention, a hole is first dug having a wall, thereupon a reticulated structurels in '30 serted into the hole to forni with the lateral `Wall of said hole an annular space, and

thenA concrete is poured' into the annulary space thus formed, whereupon the liner concrete will pass through the interstices of said wall, to prevent the passage of the.

coarser concrete therethrough and the finer concrete which is disposed on the inner face of the reticulated structure, then smoothed down ifdesired to form a iinished inner face 40 for the Wall being constructed.l The reticulated member particularly adapts itself first l v to serve as a mold face in the construction of the concretestructure, thenx to permit its' being. embedded 1in theconcrete yto subse- I '45*.quently serve asa permanent reinforcement for the structure when crlrnpleted, and fur- A therinore to' coperate with the concrete itself tolretain the coarser concrete where most required for the stability of the structure and to'permit' the automatic distribution of the'ner concrete sov that it can'lbe utilized to the best advantage, namely, to be quickly formed into a finished inner face for the completed structure.

5t My inventionr also relatesto a l.certainimhproved type of construction having the above Specification of Letters Patent.

substantially vertical lateral characteristics and particularly adapteld for sewage disposal systems or other installations in which it is desirable to form al con,v vcrete tankbelow the surfaceof the ground. This constructiom, in which 'the' mold'and4 reinforcing means are the sa y e, has the very great advantage of being 'adapted to be packed Ainto small compass,

1n the accompanying drawings, which 7o form a part of thisspeciiication, Figure l 1S a vertical sectional view of aA Isewage dis: posal system illustratingV my improved method of construction. Fig.'2 is a. fragmentary vertical part of the wire mesh or screen, the manhole collar and the crownpiece which connects them.' Fig.. 3 is a plan view of the tank at the left of Fig. l, and Fig. 4 is afragmen'- so tary detail view, showing the manner. of

-connecting together lthe overlapping edges of the mesh or screem.` Referring to the drawings in detail, the

numeral ,l designates a combined moldA and reinforcement for a tank. Thisncom'bined5l mold and reinforcement is composed of a lsheet of wire screen which may, ample, be constructed of Sharpe gage Wire with from 2 to 2% meshes 90 No. -19 Brown &

Into the annular cavity 5- between the screen and .the earth, may be -pou-red the concrete'. Thiscncrete will beretained at one side bythe earthen wall and at the*I other side by a-Wire "10o screen. f a suitable mixture ofconcreteis used, suc as that formed by one lpart 4of cement, 2% parts of sand and 5v parts of stone, acertain portion of the concrete will pass through the .meshes of the .wire screen .110 as indicated at `7 in Fig'.

Y section-al View on an enPf 75 y largedscale showing a portion of the upper for" exs' 'A coating o-ny the inner side of the wire fabric, thus efectually embedding the fabric so that it will act as afreinforcement for the concrete as well as. initially forming a mold. When the height of the tank is considerable,

it may be advi-sable to use temporary reinforcing means forthe screen, such as naru V row hoops`8, the ends of which overlap, as

shown in Figs. 1 and 2, and which maybe -secured together by means ofthe bolts,9.

crete mixture through the mesh of the fabric at the points where they are temporarily situated does not weaken the reinforcing action ofthe wire mesh upon the concrete to any appreciable exten-t.

After the wire mesh has been erected in i lace as shown in Fie. 1 a crown iece'for the structure is mounted uponv it. This crownpiece preferably consists of four sheet metal segments 10 which overlap at their edges and are secured together by the bolts 11, thus forming a frusto-conical member. Around the bottom periphery of this member are formed a plurality of inturned lugs 12 formed by slitting the metal at 13 and l-l and then bending the lugs 12 inward. When the crwnpiece is in position, these lugs are substantially vertical and abut against the inner surface of the wire fabric, as-clearly shown in Figs. 1 and 2.\ Stove bolts 15 may be passed tluoughsuitable holes in these lugs and through the wire mesh, thus clamping the crownpiece firmly upon .the wire fabric. At is upper edge the crownpiece is secured to a manhole collar 16, which is provided with an outwardly and downwardly sloping flange 17in line with the crownpiece and to which it is attached by means of the bolts 18. The upper periphery of the manhole collar is provided with a horizontally eX- tending' flange 19, adjacent to which is an inwardly extending flange 20 forming a seat for the cover'21.

1 In Fig. 1 I haveshown' the molds in place 'for the construction of a sewage disposal plant comprising a liquefying tank at the to describe the structure in left and a lsiphon chamber at the right, together with the necessaryinlet siphon and discharge pipes, but it will not be necessary detail, since my invention is directed to the concrete construction. Fig. 1 shows a small amount of concrete G to have been poured into the space 5 between the mesh and the earth wall. In completlng the structure the concrete is poured in until this space between the wire mesh and the ground is completelyl filled and the concrete is then carriedup along the dotted lines 22 in Fig` 1, forming a conical tanks and thel like,

, lated member,

construction or crown, this part of the com crete being retained in position while hardening by the sheet-metal crownpiece.

It will be seen that the construction above described provides an efficient knockdown combined mold and reinforcement for conas it do'es, acombined mold and reinforce- 1 ment entirely constructed of sheet metal or wire screen is lifht sim le and-may be packed ,for shipment in small compass, and Y requires no iexpert erector to put it in place.

Furthermore, its use is superior to concretetanks formed with Wooden, or other molds,

yiirwhich there is no reinforcing provided,

since the wire mesh adds a considerabledegree of strength to the structure when it becomes embedded in the concrete as thel latter sets or hardens.

While I have illustrated and described only one specific embodiment of my invention, I realize that `it is susceptible of broad application and I do not desire to belimited to the precise structure shown and described.
