MOLD.

Specification of Letters Patent.

Patented Jan. 30, 1906.

Application filed May 1l, 1905. Serial N. 25i.948.

With this and other objects iny view thel present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, andl particularly pointed out in they appended claims, it being understood that'changes in theform,

proportion, size, and minor details may be made within the scope of the claims Without departing from the spirit or sacricing any of the advantages of the invention.

In the accompanying drawings, Figure. 1 is a vertical sectional view of a mold embodying -.the features of the present invention. Fig. 2 is a fragmentary top plan view thereof.

Fig. 3 is a detail perspective view of`one of the inner mold-sections. Fig. 4 is a detail` perspective view of a pair of adjacent' inner and outer posts. Fig. 5 is a detail pers ective view of one of the internal braces. ig. 6 is a fragmentary erspective view of a plate to be employed or giving an ornamental coniiguration to the exterior of the tank.

Like characters of reference designate corresponding parts in each and every figure of the drawings.

Pre aratory to setting up the present mold a sha1 ow pit is dug in the ground, as indicated in Fig. 1 of the drawings, said pit preferably having a concave bottom. After this pit or concavity has been produced the outer member of the mold is set u This'outer member consistsof a series of s eet-.metal sec tions. l, having their ends abutted and hanged, preferably by means of external an? gie-bars 2 riveted thereto, the adjacent i langes or angle-bars of the abutted sections being detachably connected by means of bolts 3. At suitable intervals around the outer member of themold posts 4 are-driven of the mold.

into the ground in contact with the outer face of thevouter mold member, the upper end of each post rising a suitable distance above the top of the mold and provided with a crossbar 5, extendin inwardly across the top edge he post rises a short distance above the'cross-bar 5 to form a head 4 to receive the blows of a Sledge or the like when driving the post into the ground, as otherwise the cross-bar 5 would become bent and the bolt-openings therein impaired. A brace rod 6 is connected to the u per end of the post and inclines downward y and outwardly therefrom, with'its lower end anchored to the ground in any suitable manner. .By this means the outer member of the mold is eHectually braced against outward strains occasioned by the pressureof the plastic material when filling the mold. After the outer memj ber of the mold has thus been set up a suit-- able amount of plastic material is run into thepit so as to form a bottom 7 for the tank, the

upper face of this bottom portionpreferably,y

being concaved, as shown in Fig. 1.

WIien the bottom of the tank has been fin- -4 ished and before it has .become set, the inner wall-or member of the 'mold is set up, thisV member'consisting ofan annularseries of abutted sections 8, one of which has been shown in detail in Fig.'3 of thedrawings. Each end of each of these sections is ilanged, preferably by means of an an le-bar 9 riveted to theL outer face of the section, the abutted i flanges or an le-bars-of adj acent' sections being detachab y connected b means ofV bolts 10. Intermediate ofthe 'en s of each section there is an upright angle-bar 1 1, which serves to stiifen the'sectionand also for connection with brace members for centerin the inner mold member within the outer mo dmember.

Between the abut'ted ends of each pair of adjacent innermold-sections 5 there is an u standing. post 12,. which is pierced by' tiie bolts 10 and rises-abovefthe topedge of the mold, where it is provided with a transverse arm or extension `13, lapping the arm 5 and the adjacent outer post 4 and connectedthereto by means of boltsor similar fastenings 14. r

Adjacent the lower end of each stifeningbar 11 there is connected a substantially horizontal brace-bar made up of overlapped .adjustably-connected sections1'5 an 16, the

' centering member 21, as best shownin Fig. 2 of the drawings. To prevent sagging of thecentering device 21, inclined braces 22 have their upper ends connected, by means of bolts- 23,to the upper ends of the respective anglebars 11, with their lower ends connected to `one of the fastenings 18 of the adjacent horizontal braces.

When the inner and outer mold members have thus been setup, with the inner member centered and secured within the outer member, the plastic material is run into the mold through the annular open space between the top edges of the mold members, thereby to form the annular side 24 of the tank. When the sides of the tank have become set, the several sections ofthe mold members are disconnected and removed, thereby leaving the.

tank standing upon the ground vin readiness for use.

It is proposed to embed a metallic ring or band 25 in the upper outer edge of the tank, as best shown in Fig. 1 of the drawings, to protect the upper-edge of the tank against damage by draft-poles, chains, and the like when stock are drinking out of the tank.

If it is desired to give an ornamental configuration to the exterior of the tank, a series of forming-plates vmay be fitted against the inner face of the outer mold member, a por-.

tion of one of such forming-plates being shown at 26 in Figs. 6 and 1, said plates being provided with longitudinal and transverse ribs 27 and 28, arranged to form corresponding grooves or channels in the outer face o f the tank in imitationof brick ormasonry, as may be desired.

From the foregoing description it vwill be understood that the device ofthe present invention Aincludes comparatively few parts,

which may be conveniently assembled and set up out of doors, so as to leave the molded tank standing in the place desired lfor use.

After the cast has been completed the sections of the mold may be conveniently removed and remployed to produce another tank. It is proposed to have all of the parts of the device formed of metal, so as to Abe durable and to withstand the effects of cli matic changes.

While the present embodiment of the'invention discloses a circular tank, it is of course obvious that other shapes of molds may be produced. Moreover, by adding sections the size of the mold may be increased, and the size may of course be decreased by removing one aormore sections. It`will now be understood that the radial brace members are adjustable endwise, so as to lengthen and shorten the same in accordance with the size of the cast to be produced.

It Will'here be explained that thecement for the sides of the tank should be run'into the mold before the bottom has become set in order that there may be an intermingling of the cement of the bottom and sides of the tank to produce an integral structure and to obviate a\ weak joint between the bottom and the sides of the tank. y

Having fully described the invention, what is claimed is 1. In a mold ofthe character described, v

their upper ends provided'withlapped arms, and fastenings connecting the arms.
