OF NEWARK, OHIO.
WELL-PIT-IVIOLD FRAME.
Specification of Letters Patent;
Eatented May 23?, 1
Application filed October 30, N05. Serial No. 285.208.
To (1. whom it may concern:
Be it known that 1, WILLIAM H. LUCAS, a citizen of the United States, residing at Newark, in the county of Licking and State of Ohio, have invented certain new and useful Improvements in Well-Pit-Mold Frames; and I do 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 itappertains to make and use the same.
This invention relates to improvements in molds ior forming the mouths or necks upon cisterns, catch-basins, and similar structures of concrete or other plastic material.
The object of the invention is to provide a simple, durable, and inexpensive mold of this character which may be adjusted'to form mouths or necks of different diameters upon a concrete cistern or other structure.
\Vith theabove and other objects in View the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter described and claimed.
in the accompanying drawings, Figure l is a perspective view of my improved form or mold. 2 is a vertical sectional View through the same. Fig. Sis a detail transverse sectional View, on a larger scale, taken on a lane intersecting one of the slots in the HIOlCl lDOClY and also partially intersecting one of the screws and. nuts; and Figs. 4 and 5 are plan views showing the mold in use for forming cisterns with round and square tops.
My improved form or mold 1 is adapted for use in connection with molds for forming cisterns, wells, catch-basins, and similar structures of concrete, and it is adapted to be supported in a vertical position upon the converging top sections of such a mold, as shown in Fig. 2 of the drawings. The mold 1 is formed, preferably, from a rectangular piece of sheet-steel, galvanized iron, or the like by bending the same so as to form a cylinder and adjustably securing its overlapping edges 2 3. This adjustable connection between the overlapping edges is preferably effected by forming in the inner edge a longitudinal series of transvcrsely-cxtending slots 4 and by providing upon the other edge inwardly-extending screw-studs 5, which are adapted to Each screw-stud 5 consists of a threaded body which passes throughan opening in the edge 2 and which has upon its outer end a large flat head 7. The latter, as clearly shown in Fig. 3 of the cure the overlapping edges 2 3.
mg this ad ustable connection 1t will be seen .5, sons to. clamp said studs at any adjusted point 1n the slots 4:, and thus adjustably se--- By providthat the interior diameter of the mouth or neck of the concrete cistern or the like may be varied as desired.
In using the form or mold 1 the concrete is packed around the same and the top or up per end of the mouth or neck of the cistern may be formed circular, as shown in Figs. and 4, or square, as shown in Fig. 5. in the former case an annular band or ring 11 is e1n-- ployed, and in the latter case a square frame 12 of wood is preferably employed.
F rom the foregoing description, taken in connection with the accompanying drawings,
the construction and operation of the invention will be readily understood without requiring a more extended explanation.
Various changes in'the form, proportion, and the minor details of construction may be resorted to without departing from the prim ci'ple or sacrificing any of the advantages of this invention as defined by the appended. claim.
Having thus described my invention, what 1' im as new, and, desire to secure by Let-- tors atent, is-
'lli hercin-describcd mold comprising a cylindrical metal body portion 1, having overlapping edges, the innermost edge being provided with transversel y-cxtendin g 4, screws 5, provided with heads 7, secured to the outer overlapping edge of the body portion by means of-rivets 8, said screws 5 extending through the slots 4 and fitted with winged nuts 9 for adjusting the size of the body portion, and a ring 11 littcd around the upper end of the cistern outside the body portion l, essentially as described.
In tcstimony'whcrcof have hereunto set my hand in prcsenceof two subscribing witnesses.v
