TANK-FORMING DEVICE.

SPECIFICATION forming part of Letters Patent No. 760,911, dated May 24, 1904,

Application filed September 21,1903. Serial No. 173,990; (No model.)

- To aZZ-whom it may concern.-

Be it known that I, WILLIAM M. MoNEIL, a' citizen of the United States, residing in the city of Portland, in the county of Jay, and in the State of Indiana, have made new and useful'Improvements in Tank-Forming Devices, of which the following is a detail exposition of the mechanical construction of the essential requisites thereof, followed by a. lucid statement of its intended operation, whereby others may construct and operate the same by reference to the accompanying drawings, forming a part of this specification.

' This invention relates more particularly to the construction and arrangement of a device 'for forming tanks or the like above the surbination of tested and simple mechanical in-' strumentalities arranged to produce the highest measure of efficiency and that with a material reduction in' expense and in manual operations.

Another object is to provide a device for the purpose'stated by the aid of which cement tanks or the like may be'formed expeditiously and easily, to provide means for assembling the various parts positively, and for as easily removing the various parts after the material of the tank or the like has sufficiently hardened and stonified; and still another object is to generally improve and simplify the construction and operation of devices of this general character. I

Other specific objects and advantages of my invention will be apparent from the following detail descriptionand from an inspection of the accompanying drawings, forming a part thereof.

of the ground.

The invention consists in the construction and arrangement of the several essential elements, together with the form and disposition of the various details and the manner of their assembly.

With the above-named objects in viewIwill now take up the detail description of the invention, which I will endeavor to place in such clear and concise terms that its construction may not be misunderstood or that its intende "operation may not be'misconstrued. I

Referring now to the drawings, Figure represents a central vertical section of my assembled mechanism, taken on the line Y Y of Fig. 2, showing both the inside and the outside tiers of' sections. Fig. 2 is acentral hori- Zontal section of my assembled mechanism,

takenon the line XX of Fig. 1, and also showing both the inside and the outside tiers of sections.

My improvements herein shown anddescribed are intended primarily for use in forming cement tanks or the like above the surface However, it will be apparent that at least some of the parts will be applicable in connection with cistern-forming devices, as specifically described and claimed in my application relating thereto filed simultaneously herewith and bearing same date thereof and serial number next thereto.

This present construction consists, essentially, of two tiers of sections of different circumference set up vertically in circular form with a space therebetween, as shown. The

sections of the inside tier are each formed of: an oblong metal plate A, with a rib B secured to and extending along one of its longer sides and cross-ribs 0 extending across the top and bottom of the inside of the plate A and se- IOO 6o tier of sections are concave, while the faces of cured thereto and extending from the rib B to near the opposite edge of the plate A, leaving the edge of the plate A opposite the rib B a tongue to overlap the edge of the adjoining plate when the device is assembled. Near the free end of the inside face of the rib G is a staple 1, loosely securing the elongated link 2, and near the opposite end of each rib O is a pivotal L-shaped dog 8, adapted to be revolved, but not removed. When two of the sections are brought together, as in Figs. 1 and 2, the dog 3 may be turned to point toward the staple 1, and the link 2 of the opposite section may then be placed over the shank of the dog 3, and the dog is then turned in the opposite direction, as in Fig. 1, which will lock the two adjoining sections together, as shown.

' Secured to the inner faces central of the upper and lower ribs-C, parallel with the rib B, is a brace D, the center of which is deflected to touch the plate A of that section, where it is secured by a rivet or the like, the ends of the brace being secured to said upper and lower ribs C in like manner, as shown.

To provide means for disassembling the sections after their work has been accomplished,

-I provide the adjoining edges of two of the sections somewhat different from the others by the employment of the construction shown most clearly in Fig. 4 and is described as follows: In the end of the rib of one of said sections is a dowel-pin 4:, and in the opposite sec tion the rib C is formed shorter than in the other sections. A bolt 5 projects through the rib 0 near said shorter end, with a nut 6 operating thereon. 1 The index E denotes an angular iron having a long portion with a slot 7 disposed longitudinally therethrough and with a relatively shorter end bent at right angles to the longer end, with a hole therethrough to receive said pin 4. By the above it will be seen that after the other sections have been positioned the two modified sections may be positioned with the metal plate A of the section carrying said angle-iron overlapping the metal portion A of the opposite section having the dowel-pin, by which construction it is apparent'that the disparency between the meeting of the said two sec tions may be taken up by moving the angleiron E toward said opposite section, entering the pin 4 in the hole in the angle-iron, as shown, and then by tightening the nut 6 the sections are prevented from being pressed inward from without.

The outer tier of sections are similar in construction to those above described except that their curvature is in the opposite direction theretothat is to say, the faces of the inner the outer tier of sections are convex, with the faces of the latter opposite to, parallel with, and disposed some distance apart from the former, as shown. Consequently the circumference of the outer tier is somewhat greater than that of the inner tier. The outer sections are composed of a plate F, having cross-ribs G, and-with the link connections for each section similar in construction to the above-described link connection on the inside sections except that with the outside section the link connections are on the outside. In the case of the last outside sections they are similarly formed to the above-described last two of the inside sections except that a plate H is provided in place of the angle-iron, which plate is bolted at one end by the bolt 8 near the edge of one section and extends out over the opposite section with a longitudinal slot 9 therethrough to receive the bolt 10, which latter is secured in the cross-rib of the said opposite section and with a nut 11 on said bolt to secure said plate H at desired points, as in Fig. 5.

When constructed as stated, the two tiers of sections are then set up in the manner shown with a space between their faces of a width the same as the predetermined thickness of the wall to be formed thereby and are secured to the earth at the bottom as follows: Vertically through both top and bottom crossribs C and G are holes, as shown, the lower holes being adapted to receive the pins I, which are to be driven therethrough into the earth or whatever the tank to be formed is to rest on. In order to space the two tiers of sections and retain them the proper distance apart, I provide a number of plates K with holes therethrough along their lengths, as shown in Fig. 3. Said plates are to be laid on the upper ends of the sections across from the inner to the outer tier of sections, and pins 12 are to be inserted through said soles in the plates K and thence into the corresponding holes in upper cross-ribs C and G, above referred to, as shown in Fig. 3. After the device has been set up and assembled, as shown and described, the space between the sections may be filled in with the plastic or deliquidous cement and allowed to harden therein, after which the various parts may be disassembled and removed anda bottom formed in the tank of same material as said walls, and thus accomplishing the objects of this invention.

In the accompanying drawings I have shown the construction to contain only eight sections in each tier simply as a matter of convenience, whereas in actual practice a greater number of sections may be employed, if desired, in order to attain the desired circumference and at the same time making the sections easy to handle and transport. Y

From the above description, taken in connection with the accompanying drawings, it will be apparent that I have produced an improved tank-forming device embodying the objects elsewhere referred to in this specification and shown in the accompanying drawings.

While I have illustrated and described the best means now known to me for carrying out the objects of my invention, I desire it to be understood that-I do not restrict myselfto the exact details of the construction shown and described, but hold that any slight changes or variations therein as would suggest themselves to the ordinary mechanic would clearly fall within the limit and scope of my invention.

Having now fully shown and described my invention and the bestmeans for its construction to me known at this time, what I claim, and desire to secure by Letters Patent of the United States, is'

1. A tank-forming device comprising in combination, an inner tier of separable sections, an outer tier of separable sections some distance from the said inner tier and parallel therewith, said sections of the inner tier being formed of an oblong plate, ribs secured to and extending along one of the sides of the plate, cross-ribs extending across the top and bottom of each plate from said side rib to near the opposite edge of each plate wherebya tongue is formed of one edge of each plate to overlap the edge of the adjoining plate, staples secured in the inner face of the cross-ribs, an elongated link carried by each of said staples, a pivotal L-shaped dog mounted on the opposite ends of the inner faces of the cross-ribs and adapted to enter the eye of the link of the opposite section to lock the sections together, means for disassembling the inner sections after their work is completed, means for assembling'and disassembling the outer sections, means for connecting the inner and outer tiers of sections at the top, and means for securing the sections at the bottom, all substantially as shown and described.
