FORM FOR MAKING PIPYE.
Specication of Letters Patent. Patented Jan. 17, 19,22.
Application nled November 29, 1919.; Serial No. 341,494,
' Making Pipe, of which the following is a specification, reference being had therein to the accompanying drawing.
My invention relates to improvements 1n forms for making pipe and my object is to provide a form of inexpensive materlal,
' which may be setup in a minimum of time,
and into which plastic material may be run to form a continuous, jointless pipe.; a further object being to provide such form with a simple and inexpensive reinforce 'for the ipe. t p In the drawingsl Fig. l is an elevation, partly in section of a form embodying my improvements.
Fig. 2 is an enlarged perspective view showing the arrangement of the reinforces for the pipe.
Referring by numerals to the drawings 5 designates .the outer form and 6 the inner I form, 'both l'of which are made as tubes of covered, by a sleeve 11,
. relatively .cheap material, such as paper. F or holding the inner form 6 centered within the outer form to serve as a core, I provide 'aspider 7, which surrounds the inner form and 1s provided with arms'S which engage the both forms (as .shown inl Fig. 2).
The spider I also employ as a means for properly supporting the' reinforce rods 9 which as shown in Fi 2 "are extended lengthwise between the orms 5 and 6 and secured to the arms 8 of the spider, as by being wrapped thereabout.
Both tubes 5 and 6 are made in lengths convenient to handle? and are joined for continuity by means of sleeves 10 and 11, which are made to frictionally hold in place over the joints between the tubes. n Adjacent each joint in the outer form there 1s a vent hole 12, which is arranged to be after running the plastic material, and which vent hole serves as a means to show ow of material at times when the sleeve l1 1s moved to, a position uncovering the vent.
' To provide for tapping into the pipe I employ a core in the form of a metallic nipple such as 13 which is extended through both forms so as to imbed'and be secured 1n the wall of the pipe.
and until said mate-rial hardens. .The
The formrmay be made of-any material having adequate strength to retain its shape underfthe pressure ofthe plastic material 1astic material may be made of any ingredients which will have squiicient strength when set to resist the internal or external stresses towhich it is subjected. In practice I have used Portland cement with sand in varying proportions, frequently one part of cement to three parts lof a mixture of sand and gravel.- l 4 An underlying principle of my form is that it shall be made of material of such low cost that it will be left permanently in place, so saving the labor cost of setting up and removing the form as ther work pro'- ,gresses 'When paper forms are 'so employed in building conduits, pipe-lines and the like the paper. will ultimately disintegrate and be removed by the exposure of the inner tube to the flowing content of the pipe,
and the action of the elements upon the outer tube will remove the latter.
Obviouslyany suitable and equivalent material, so inexpensive as to be left in place when its work is done, may be used instead of paper, and the word paper is employed in the claims with this understanding.
ln building a continuous pipe by the use of my invention the inner tube 6 will lbe extended in advance of the outer tube 5 (as shown in both figures of the drawing) as the work progresses, and will be used, when desired, to convey the water used in mixing the concrete, to the point in the progress of the work where the concrete-mixing is done. The tube 6 may be tapped, if desired, by removing the nipple 13, to secure water supply at any point within the length of the pipe.
The tubes 5 and 6 and sleeve 11 may be treated with coal-tar, paratline or any other desired preservative or water-proof material,
tween the lengths, spiders for holding the OFI-ica inner tubes centered and arranged hold longitudinal reinforce rods.
2. A form comprising inner and outer tubes,
at intervals and sleeves movable over the there being vents in the outer tubes connecting said4 sections;
outer tubes foi-.covering and uncovering the ,Y
with exterior sleeves uniting said sections;`
and a core composedof tubular sections of uniform diameter, and exterior sleeves unitin said sections, said core being of material adpted to be left permanently in place in the pipe when formed.
4. The improved form for plastic material consisting of extensible inner and outer tubes arranged to provide a continuous space between said tubes wherein said plastic material may be introduced; the inner tube being adapted' to carry liquid to a point in advance of the front end of the outer tube. v
5. The method of building a continuous conduit, consisting of seating in place an inner tube comprised of sections and sleeves next seating in place about said inner tube an outer tube comprising sections and sleeves connecting said sections of greater diameter than said inner tube; holding said tubes in alinement with but out of contact with each other;
and iiowing'a filling of plastic material into the space thus formed between the tubes.
6. In a form for making pipe, an outer sectional tube, an inner sectional tube; and a spider for holding said tubes Vcentered relatively to each other and 'arranged to hold longitudinal reinforce rods.
inner and outer forms and adapted to hold longitudinal reinforce rods.
.8. In a device for forming concrete pipe, an inner form comprising tubular sections and connecting means mounted on the exterior of said sections, said inner form being of material suitable to remain imbedded in the pipe when completed; and centering devices Ainterposed between said inner and outer forms and so arranged as not to obstruct the flow of plastic material while the pipe is being formed, and to remain in place inthe completed pipe.`
9. In a formvfor making pipe, a continuous'inner tube of predetermined length; a continuous outer mold of corresponding length; centering spiders arranged to hold said inner tube and outer mold in their proper relative positions during the flowing of pipe-forming material into the mold; said spiders being adapted to hold longitudinal reinforce rods, and vents formed in the outer mold.
In testimony whereof I hereunto aiiix my signature.
