` Be it known that I, HENRY KNIGHT @anni '(illiiiiw.
HENRY KNIGHT, or BROOKLYN, New, Yoan'.
Leners Patent-Nq. 105,954, dated August 2, 1870.
mpnovnn WATER-Prez: MQLD.
The Schedule` referred td inthese Letters Patent and making-part of the lame.
To all :pliant it mag/.concern i of Brooklyn, inthe county of Kings and State of New York, have invented a new Mode of' Molding'Pipes ofcement and'other plastic material; and I do hereby'declare that the following is a full, clear, and exactdescrip,`
tion thereof', reference heilig had tothe accompanying drawing .making part of this specification, in which-'- v Figure 1 is a vertical diametrical section, showing a pipe complete in its mold. Y Figure 2 is 'a top view of one of the collars or beveled rings. n
Figure 3 is a. top ring, and the core. 4
VFigure 4 is a section through a beveled ring which differs 'slightly from thefring shown in figs. 1, 2, and 3. Similar letters'of reference indicate corresponding parts in the several figures. This invention relates to an improved mode of makview of Vthe mold, the beveled ngcement pipes, which have beveled mal'e and female ends adapted to fit one into the'other, and form iush joints, `externally as well as internally.
- Hitherto, cement pipes, which were adaptedA to bc jointedtogether, as above stated, have been produced by forming the female ends at the lower end of and 'within the mold, and by-.forining the male ends around a central core, above the upper end of the mold. y v' One great objection 4to this methodof formingthe maleends is, that the material of which the pipes y are formed requires to be so dry to do this that' the' process is very diliicult and slow, and -a perfect end cannot be madewithont great labor. y
.The nature of my invention, consists in a m'old composed of a central-core, a flanged base, an intery nally shouldered shell,`and ariug or collar; the said parts being so constructed and applied that, while the whole pipe is molded within the shell, the male coupling-end of the pipe is formed in the lower end ofthe same, 4andthe female coupling-end is formed in the upper end" thereof; all as will be hereinafter described. To enable others skilled in the art to understand my invention, I will explain its construction and operation.
' In the accompanying drawing- A represents'the body of the improved pipe-mold, which is made of two longitudinal halves, and provided with lugs'a'a., for receiving clamps b b, .that hold the halves together.
The body A, shown in but other forms may be adopted, according to the form -of the pipes which it is desired to make.
The body of the mold-lis made somewhat' longer than the pipes which it isdesigned for making; and
.the interior of the lower end of this 'body or shell AA is contracted by the formation of an annular 'beveled Vends of the pipes G.
the drawing, is cylindrical,
surface, g', .terminating above and below in annular shoulders, as shown in iig. 1.
These surfaces correspond to and produce the vb'evelcd surfacesand shoulders that cm'istitutethe male C represents the core, and 0' its enlarged base, on which latter-the. body of thev mold rests when the core is in place, as shown 'in iig; 1. The core O extends up to or above the upper end 'of the body A, and leaves a space between'it and the latter, which is equal in thickness to the thickness required of the pipes. I do n ot mean to be understood as limitingA myself' to the precise mode of constructing the core shown inthe drawing, as other equivalent modesmay be adopted. e
B'lis a'ring, which is adapted to slip over the upper end 4of' the core,'aud extend partially within the space between it and the body A. The superior surface of this ring is dat, and pro vided with a bail vor handle, D; the inferior surface is beveled at g, and otherwise shaped so as to correspond precisely with' the female ends of the pipes,"which are' connterpartsof themale ends, as shown in iig.-1.
The circumference of this ring is provided with three or more lugs, c, which rest 4on the upper endof" the body A when the ring is forced home. The upper end of thel vbody of -t-he mold is slightly beveled, for the purpose of allowing the! ring to drop down more freely.
The beveled ring B, shown in fig. 4, does -not differ substantially from the ring B of figs. 1, 2, and 3.
The operation'ofvproducng vpipes with the mold above described is vasi-follows:
The. shell or body A and corefC having together, andthe space between them-filled with plas' tic material, the ring B is slipped o'ver the upper end' of the core G, and forced down in place, thus producing the socket or female end of the pipe at .the upper end of the mold, and within the body or shellthereof, as shown in Iig. 1.
What I claim as my inventin, and desire to secure by Lettersv Patent, is-
The arrangementof the loose collar B, constructed as described, stationary coreC, flanged collar C', and4 mold-shell A, the several parts being combined and operated in s uch a manner that the female couplingend g of a pipe, wit-hout a collar, is formed entirely within the mold, and atv the upper end of the same, whilethe male end g" of the pipe is formed within the mold-shell, and at the lower end of the same, all as shown and described.
