FORM FOR MAKING CISTERIQS.

Specification of Letters latent.

Patented Nov. 3, 1908.

Application filed March 21, 1908. Serial No. 422,469.

To all whom it may concern:

Be it known that I, THOMAS E. LEPLEY, a citizen of the United States, residing at Blue Springs, in the county of Gage and State of Nebraska, have invented a new and useful Form for liaking Cisterns, of which the following is a specification.

This invention relates to forms for constructing cisterns, cesspools, vaults and other under ground structures from cement, concrete and similar plastic material and has for its object to provide a strong, durable and thoroughly efficient device of this character capable of being quickly set up for use and readily knocked down and compactly folded for transportation or shipment.

A further object of the invention is to provide a mold or form including a plurality of side stays having top stays pivotally connected therewith and adapted to bear against. the neck band or section, the top stays being detachably combined with the neck band so as to permit the side stays to be readily witl drawn from the interior of the cistern after the cement has thoroughly set.

A further object is to provide improved means for clamping the top stays in engage ment with the neck section.

A still further object of the invention is generally to improve this class of devices so as to increase their utility, durability and efficiency.

Further objects and advantages will appear in the following description, it being understood that various changes in form, proportions and minor details of construc tion may be resorted to within the scope of the appended claims.

In the accompanying drawings forming a part of this specification: Figure 1 is a side elevation partly in section of a form or mold constructed in accordance with my invention showing the same set up for use. Fig. 2 is a top plan view partly in section. Fig. 3 is a sectional side elevation. Fig. & is a detail perspective view showing the manner of connecting the side and top stays. Fig. 5 is a side elevation partly in section of the completed cistern, the stays or supports being shown in position to be withdrawn from the interior of the cistern. Fig. 6 is a transverse sectional view taken on the line 66 of F ig. 3.

Similar numerals of reference indicate cor 'esponding parts in all of the figures of the drawings.

The improved mold forming the subject matter of the present invention includes a series of side stays or supports each comprising a plurality of

sections

5 and 6 having their adjacent ends pivotally united by a hinge connection 7. The lower ends of the side sections or stays 5 are adapted to bear against the ground while the upper ends of the top sections or stays 6 bear against an annular band or neck section 8.

Extending inwardly from the upper edge of the neck band or section 8 is an overhanging flange 9 having a plurality of perforations formed therein for the reception of clamping bolts or pins 10. The lower ends of the bolts 10 are provided with hooked terminals 11 which. engage suitable eyes 1:2 fastened to the inner longitudinal edges of the adjacent top stays 6. The upper ends of the bolts 10 are threaded at 13 for engagement with suitable clamping nuts 14, which latter bear against the flange 9 and serve to clamp the top stay sections 6 in engagement with the exterior walls of the neck section or band 8, as best shown in Fig. 3 of the drawings.

Attention is here called to the fact that the exterior walls of the neck band or section 8 are slightly inclined or tapered so as to permit the latter to be readily withdrawn from the neck of the cistern after the cement has sufficiently set, the upper ends of the top stays 6 being correspondingly inclined or beveled at 15 so as to conform to and snugly engage the tapered. walls of said neck section.

The interior walls of the neck section at the lower or reduced end thereof is preferably reinforced and strengthened by an annular band 16, which latter also forms a bearing for the hooked ends of the bolts 10 and serves to maintain the belts in vertical position so that when the clamping nuts 14 are tightened the hooks 11 will exert a direct upward pull on the eyes 12 and thus prevent twisting or torsional movement of the parts.

Surrounding the exterior walls of the neck section or band 8 is a collar or flange 17, which latter is spaced from the neck section 8 to form an intermediate molding compart'ment 18. The flange or collar 17 is detachably combined with and supported in spaced relation to the neck 8 by means of a series of horizontally disposed brackets 19 one end of each of which is detachably secured to the flange 9 by bolts or similar fastening devices 20, the opposite ends of the brackets being bent downwardly to form depending arms 21 for attachment to the exterior walls of the collar or flange 17, shown.

In constructing a cistern an excavation 22 is first formed in the ground after which the side stays are assembledin substantially cir cular form with the inclined ends 15 of the top stays bearing against the exterior walls of the neck section or band 8, the lower ends of the side stays 5 being temporarily secured to the ground by pins or similar fastening devices 48. The hooked ends of the bolts 10 are then introduced in the eyes 12 with their threaded ends passes through the apertures in the flange 9 and the nuts 14L. adjusted to securely clamp the mold in operative or set up position. After the mold is thus assembled a casing section 2 1 is placed in position around the exterior walls of the mold or form and in engagement with the side stays 5, a quantity of cement being subsequently introduced between the casing section 2 1 and the adjacent wall of the excavation 22 and said cement tamped in the usual manner. Another casing section similar to the section 2 1 is then placed in position on the exterior walls of the mold or form and more cement shoveled into the excavation adjacent said section, this operation being continued until the side walls of the cistern are formed. After the side walls are formed the 'ement is introduced in the molding compartment 18 and thoroughly tamped to produce the neck of the cistern.

In order to remove the mold or form from the cistern the claniping rods or bolts 10 are first removed by releasing the nuts 14!; after which the neck section or band together with the collar 17 is withdrawn from the neck of the cistern. The side and top stays of the mold are then moved to the position shown in Fig. of the drawings and in which position said stays or supports may be readily withdrawn from the cistern through the mouth thereof. By forming the side supports of the mold of pivotally united sections the lower sections may be swung laterally on the hinges 7 so as to permit the formation of cisterns having either inclined or vertical walls.

Attention is here called to the fact that the brackets are provided with elongated slots 26 so that by releasing the fastening devices 20 said brackets may be adjusted laterally to vary the width of the molding compartment 18 and consequently vary the thickness of the wall of the cistern at the neck thereof.

The form may be made in difierent sizes and constructed of wood, metal or other suitable material, and the sheathing or covthin boards, whichever is found to be the most desirable.

Having thus described the invention what is claimed is:

1. A mold for cisterns including a neck section, spaced side supports bearing against the exterior walls of the neck section, a covering for the side supports, a collar spaced from the neck section, brackets forming a connection between the upper edges of the neck and collar, respectively, and means for clamping the side supports in engagement with said neck section.
