HARRY E. HAMILTON, OF FOUNTAIN CITY, INDIANA.
MOLD.
To all whom it may concern Be it known that I, HARRY E. HAMILTON, a citizen of the United States, residing at Fountain City, in the county of Wayne, State of Indiana, have invented certain new and useful Improvements in Molds; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to cisterns, water tanks and the like, and the forms for mold structures for building the same, and'more particularly to mold devices which are made in sections and adapted to be removed after the structure is completed.
The principal object of the invention is to improve and simplify the construction of devices of this character.
Another object of the invention is to provide a cistern form consisting of wall and top sections respectively formed of separable staves, plates carried by each stave for clamping the adjacent edges of adjacent staves together, the upper ends of said plates being outwardly curved to form seats for receiving the lower edge of the top.
Another object of the invention is to provide a mold of the character described which is extremely simple in construction, being composed of a minimum number of parts, and is therefore cheap to manufacture.
With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claim, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
In the drawings: Figure 1 is a vertical Specification of Letters Patent. Patented Mar, 23, 1915. Application filed September 7, 1911. I
Serial No. 648,088.
Fig. 3 is a detail horizontal section taken through the top of the mold.
Like reference numerals designate 'corresponding parts in all the figures of the drawings.
Referring to the drawings, 5 designates the usual pit in which the cistern is molded.
My invention comprises a cistern mold consisting of a wall section A and a top B. The wall section comprises a plurality of staves 6 formed from flat metal and disposed in overlapping relation. Formed in each stave adjacent the outer edge 7 thereof is a pluralityv of openings, and disposed within said openings is a plurality of bolts 9 having nuts 10 associated therewith.
Clamping plates 11 are each formed with corresponding openings for receiving said bolt, and these plates extend longitudinally against the inner faces of said staves, the
outer edges 7 of the staves and the corresponding edges of the plates co-acting to receive the free edge of the adjacent staves,
and by means of the nuts 10, said clamping plates are each forced to tightly grip the adjacent edge of the adjacent section to firmly secure said staves against sliding.
The upper ends 12 of the plates are bentinwardly from the staves to form. guide fingers and consequent seats.
The top B is formed from a plurality of sheet metal staves 13 having their sides 14:1& respectively converging upwardly. These staves are arranged in overlapping relation similar to the staves of the wall, and the outer edges are formed with a plurality of openings. Disposed within these openings are bolts as shown having nuts 17 associated therewith for securing the clamping plates 18, and by means of which said staves may be held together. The lower ends of the staves are downwardly bent to form flanges 19 and the upper ends of said staves are upwardly bent to form upper flanges 20. In positioning the top B upon the wall A, the lower flanges 19 are disposed between the staves 6 and the guide fingers 12 of the clamping plates, and by this means the top is held in its proper position upon the wall. The upper flanges 20 of the top are employed for forming the usual mouth of the cistern.
From the foregoing, it will be observed that after the cistern has been formed, the staves of both the top and wall can be easily taken apart and removed from the structure thus completed.
hat is claimed is:
A mold comprising in combination, a wall section consisting of a plurality of staves arranged with their adjacent edges disposed inoverlapping relation, a clamping strip extending longitudinally against the inner face of the outer edge of each stave, the upper end of each strip being inwardly bent to form a guide finger, means engaging each strip and the outer edge of each stave for clamping the inner edge of each adjacent stave between the strip and the outer ed 'e of each adjacent stave, and a top section seated between the stares of the wall section and the inwardly bent fingers of the strips.
In testimony whereof, I afiix my signature, in presence ofv two witnesses.
