Specification of Letters Patent.

Patented Jan. 14, 1908.

Application filed Julie 29. 1906.I Serial No. 324.069.

To all whpm it may concern:

Be it known that I, ANDREW G. PETERSON, l a citizen of the United States, residing at Wahpeton, in the county of Richland and State of North Dakota, have invented a new and -useful Cistern, of which the following is a s ecification.

he present invention relates to cisterns or reservoirs for the storage of Water and other liquids, and it relates more particularly to cisterns constructed of concrete or other selfv The invention has for its objects to iniprove and simplify devices of this characterJ so that they are easy to construct, substantial and durable, inexpensive to manufacture, and readily accessible for cleaning.

With these objects in view, and others, as will appear as the invention is better understood, the'same comprises the various features of construction and arrangement of parts described hereinafter and set forth with particularity, in the claims appended;

hereto.

In the accompanying drawing, wnicli illustrates one embodiment of the invention, Figthe cistern more particularly adapted for unportion of the tank for adapting the saine for above ground use. `Fig. 3 is-a detail view of pipe.

Corresponding parts in the seveial figures are indicated throughout by similar characbody 1 and cover 2 are provided with a numters of reference.

Y Referring to the drawing, 1 represents the in transverse horizontal section may be circular or polygonal, as desired, the cylindrical sha e being preferable. Arranged on the top 4of tiie'body 1 of the cistern is a cover 2 shaped in the form of a cap with a contracted throat 3 that is closed by a cap or plate 4. The

of p astio material made of one part of .Port-l land cementand one and a half parts of sand. These proportions are satisfactory for certain results, but may be-changed, and also other materials maybe ein loyed, if desired. Suitable forins are provi ed for molding the parts of the cistern, as will be readily understood.-

.Embedded in the walls of theI body 1 and cover? are iron members 5 for the purpose. l

, ofreinforcing the walls seas to withstand the i pressures subjected to them. The members l 5 in thebody 1 eaclicomprises a strip of iron of suitable cross section that extends diametrically of and embedded in the bottom of the body and extends upwardly' from thel ends of the bottoni portion 6 to form side portions 7 that are embedded in the cylindrical wall of the body 1. The extremities ofthe reinforcing irons are preferably continued outwardly through and 4beyond the exterior surface of the body to forni lugs 8. Inthe present illustration, two reinforcing irons are shown, they being arranged diametrically of the cistern and in planes disposed at right angles to each other. 'It is obvious that any number of these reinforcing irons maybe employed, and further, any tWo opposite side` portions 7, instead of being connected by a common base or bottoni portion 6, may be separate. 1 The cover 2 has also embedded in its walls a plurality of reinforcing irons 5 that are arranged in the same planes with the irons in the body 1, so that thelugs 10 formeflby their lower ends rojecting outwardly from the cover, will aine with the lugs 8. The lugs 8 and 10 are provided With registeringperforatioiis to receive the bolts 11, which latter hold the cover securely on the cistern body. The joint between the cover and body is formed by an annular groove in one of'them, which is V- shaped in a radial direction and the other member is correspondingly shaped to iit the groove. Such a joint l'orins a perfect seal when the cover is securely bolted to the body. -For further reinforcing the cistern, the

ber of circumferentiallioops'or bands l2 arranged in any'desired i'nanner. The neck 3 of the cover is formed with an annular shoulder 13 against which fits a corres )ondingly shaped shoulder 14 on the cover p ate 4. The-cover plate may be held in place by its -.own Weight, or by any suitable device, as desired.. Extending into the cistorn through the cover are pipes 15 and.16, the saine snugly iitting in openings in thecover plate for :receiving them. The pipe 15 serves to convey the water or other liquid to be stored into the cisterii, and extends only a short distance below the cover late. It is provided with a self closing va ve 16 fulcrunied ics at 17 on a lug 18 and maintained in normally closed position by the adjustable counterbalance weight 19. The valve is so weighted that it will automatically open under the weight of liquid iii or flowing through the point more or less elevated above the floor or ground,l a connection may bemade With the cistern adjacent the base thereof at a point indicated at 20, Fig. 2. This connection a may supply one or morefaucets located rials, arrangement of parts, and proportions more or less remote from the cistern in a suitable pipe system, as vWill be `readily underf stood, or a faucet,'2l, as shown, may be applied directly to the cistern at the 1point 20.

I have described the principle of t e inven-` tion, together `with the apparatus which I now consider to be the best embodiment thereof, but I desire to have it understood that the apparatus shown is merely illustrative, and that various` changes in the matemay be resorted to, as are with-in the scope of the invention.- I also desire to have it understood that the term cistern is'to be construed to mean any receptacle or reservoir, for Water or other liquids, of all sizes, from tubs torailroad tanks.

` Vhat is claimed is- 1. 'A cistern comprising a hollow body `made of plastic material in one homogeneous piece, and a plurality of reinforcing metal strips embedded in said body, each metal strip extending diametrically across .the bottom of said body, then up the sides in a vertical direction to a point near the top the ends thereof being bent outwardly to project lin a radial direction through and beyond the exv terior face of the cistern wall to form attaching lugs.

2. A cisternl comprising ka hollow body and cover each made of plastic material in one homogeneous piece, avplurality of reinforcing metal strips embedded longitudinally in the side wall of said body, the upperen'd of each reinforcing strip bent outwardly to project through and beyond the exterior face of the body Wall, a plurality of metal reinforcing strips embedded in said cover vand in alinement throughout their length with those in the body and bent outwardly at their lower ends to projectthrough and beyond the Wall of the cover, and means for connecting each'reinforcing strip in said body to an alined strip in the cover.

3. A cistern comprising a body and se arable cover each made of plastic materiaf a lurality of reinforcing metal strips embedded ongitudinally in the Aside wall of said body, the upper end of each reinforcing strip bent outwardly to project through and beyond the exterior face of the body wall, a plurality of metal reinforcing strips embedded in said cover and in alinement throughout their length with those in the body and bent outwardly at their lower endsto project through and beyond the wall of the cover, means for connecting each reinforcing strip in said body to an alined strip in the cover, and reinforcing bands extending horizontally around the exterior of said body and cover and partly embedded in the substance thereof.

In testimony that I claim the foregoing as'V -my own, I have hereto affixed my signature in the vpresence of two witnesses.
