CEMENT-CIS'IERN MOLD.
Specification of Letters Patent.
Application filed Februaryjl i, 1907.
Patented Aug. 3, 1909.
Serial No. 357,237.
To all whom it may concern:
Be it known that I, NEWMAN BRONI-IARD, of Toledo, county of Lucas, and State of Ohio, have invented certain new and useful Improvements in Cement- Cistern Molds; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form part of this specification.
This invention relates to certain improvements in cement-cistern molds, and it embodies the novel combination, arrangement and details of construction hereinafter shown, described and claimed.
In the accompanying drawings illustrative of the invention Figure 1 is a plan view illustrating my improved construction for supporting the dome of the cistern; Fig. 2 is a side elevation of the same, the central ring being in section; Fig. 3 is an elevation showing the side walls or sections of the mold and illustrating my improved fastening for the same; Fig. 4 is a perspective view of the fastening.
l'ieferring to the details, 1 indicates the elongated rectangular sections or plates 7 which when fastened together edge to edge constitute a cylindrical form for the cistern walls. Each section or plate 1 has riveted to one of its side edges a strip of metal 2 overlapping the edge of the adjoining plate and thereby effectively excluding the semiliquid concrete material from passing through between the abutting edges of the plates. At its upper end the strip 2 is bent angularly and formed with an eye l to receive the hooked end 5 of the rods 6 constituting the supports for the dome plates, indicated in dotted lines 8, Figs. 1 and 2. To the plates 1 are secured at intervals transverse metal strips 9 each of which is provided with an arch or bend 10 near one end and having a notch 11 to receive the hooked end 12 of a latch 13 pivoted near the edge of the adjoining plate. By thus protecting the free end of the latch so as to lie beneath the transverse strip when fastened, the possibility of the hook of the latch becoming unfastened by accidental contact, is eliminated. The rods 6, as before stated, are provided with hooked ends to engage the eyes -lat the upper ends of the strips 2, it being required in assembling the dome supports to first lower the rods to the position in dotted lines a, Fig. 2, before the hooks on the ends of the rods may be connected with. the eyes 4. At their inner ends the rods (5 are provided with screw-threaded upwardly projecting" studs 1% having securing nuts 15 thereon, and 16 is a flattened ring having radial slots 17 opening inwardly through the inner edge of the ring, the arrangement being such that the parts being assembled as in Figs 1 and 2, and the nuts upon the studs being tightened against the face of the ring, the rods 6 will be rigidly held in place and the dome plates firmly supported. When the concrete which forms the dome has hardened sufficiently, the nuts 15 are unscrewed, when the rods 6 which support the dome plates, and also the ring 16 may be lowered into the completed cistern, as indicated in dotted lines Z), Fig. 2, the studs upon the in uer ends of the rods moving radially inward along the slots in the ring until they are entirely free. By now lowering the rods the hooked ends may be disconnected from the e es Having thus described my invention, what I claim and desire to secure by Letters Patent, is
In a cistern mold, a plurality of rectangular plates, strips secured along the edge of each plate, the strips formed with eyes at their upper ends, and a dome support comprising a plurality of radial rods detachably secured at their inner ends and having hooks provided at their outer ends to connect with said eyes, the hooked outer ends being incapable of disengagement from the eyes when elevated, substantially as described.
In testimony, that I claim the foregoing as my own I afix my signature, in presence of two witnesses.
NFJVMAN BRONHARD.
