The mold forming the s ibjeci vrria tteryof my present invention primarily includes .a

shown in Fig. 2, this core is positioned with one end seating in the channellfuffhe base 10'an'd' plosel'y engagingfthe mm wall of, such channel, it usually being m-v-(aasary to somewhat expand theeore to" ai lpljyi it in this pos'itionb Adjacent the, opposite end of the core, I provide a plurality of spaced L'-sha-pd brackets 16*securedto the core with their free prms directed inwardly. When the core'is n place; the free arms of these brackets support a metallic expanding be thickened and reinforced.
ring 17 which is inserted in the upper end of the core to hold such end in (proper shape. It will of course be under'stoo that the external diameter of this expanding ring is equal to the internal diameter of the channel 14 of the base in order that the internal diameter of the finished ipe' section may be uniform throughout t e length of the pipe. y
The outer casing 12 of the mold is substantially identicalwith the core in its main features, being formed from a single relatively heavy sheet of resilient metal bent into the form of a cylinder with its free edges overlapping. The upper and lower edge portions of this metal sheet are, however, struck out in order that such portions of the casing may be flaredas shown at 18 in the drawings, whereby the ends of the resultant pipe section formed in the mold will It will of course be understood that this casing. 12 is equal in height to theheight of the core, althou h somewhat greater in diameter. In fact, this casing, when free of the base and top member ofthe mold, should somewhat exceed in diameter the outer diameter of the '19 being located nearer the free. edges of the casing than the brackets 20 and theieforc nearer each other. A" rod 21 has one end secured in one of the brackets 19 and its op: posite end secured in the corresponding bracket 20, while a rod 22 is simi arly secured to the other brackets 19 and "20. It
willtherefore be seen that these rods'con-' verge toward each other toward the upper end of the. casing.
A sliding clamp bar,23 is formed at its ends with eyes 24 to slidably engage about the rods 21 and in the manner shown in Fig. 1. It will of course be apparent-that movement of this clamp bar toward the brackets 20 will draw the rods 21; and 22 toward eachother and, conseql iently, cause the free edges of the casing to move to more completely overlap, and consequently contract the mold casing. ()n the other hand, movement of the clamp bar 23 toward the brackets) will correspondingly expand the casing. When the clamp rod IS in its lowermost position, the diameter of the casing is reduced to such an extent that the lower end of the casing may -.be readily introduced into the channel 14 of the base 10. One of the brackets 19 )rovided with a swing-' ingly mounted book 25, the bill of which the upper end of the mold casing in a. contracted position corresponding to that of the lower end of the mold casing when the clamp bar 23 is in lowered position, this locking of the upper end of the mold cusing, in contracted position, facilitating the application of thetop member of the mold, as will be later explained.
' The top member of the mold includes a conical shaped cap portion 27 rovided at its, free edge with a downwar ly directed flange 28 adapted to seat in the upper end of the core 11 and, consequently, center the core with respect, to the outer casing of the mold. A plurality of radiating arms 29, preferably formed integrally with this cap; connect it with a funnel member or 5 out of frust'o conical shape. The 'smal ereud of the spout is, ofcourse, directed downwardly and this end is providedwith the downwardly extending flange {ll adapted to engage about and embrace the upper end of the mold casing 12 when the top member of the mold is in place. When the top member is positioned, as shown in Fig. 2.
of the drawin r, it will be seen that the lower edges 0 the arms 29 rest upon the upper ends of the core and mold casing to support the cap portion 27 and funnel .portion 30 in proper position. Furthermore, the upper end of the core is held in properly extended position by the flange 2hv of the cap portion, while the upper end of the mold casing is held in. .l' contracted position by engageuu'ut against the inner face of the flange '31 ofthe funnel portion 30 of the uppcr'mold member.
As a rule, inmanufacturing concrete pipes with my mold; I prefer to provide each pipe section with a reinforcing element in theform of a tubular structure 32 of foraminous material of relatively large mesh. As shown in the drawings, this reinforcing element includes .a plurality of horizontally disposed reinforcing rings 33 of relatively stifi' wire supported in proper spaced relation by being welded or otherwise secured to a plurality of spaced verticul brace wires orrods 34, the upper and lower ends of these brace rods being bent about the upper and lower rings 32 as shown This reinforcing element is of a. diameter somewhat greater than the. diametcr of'the core andless. than the diameter of the mold casing in order that it may be ployed and such element is merely mentioned in this case because of the provision which I make for properly centering the 'reinforci'ng element during pouring of the concrete! Referring to Figs. 1 and 2 of the draW- ings it will be seen'that each of the arms 29 is provided intermediate its length with a pair of spacedapart downwardly depending fingers 36 adapted to straddle the upper ring 33 of the reinforcing element when the latter is in place and therefore to hold the reinforcing element in proper centralized position. v
In assembling the mold, thecore is expanded suiliciently to permit its lower end to be seated in the channel it of the base and to receive the expanding ring 17. The reinforcing element 32 isrthen positioned about the core, being centralized as accurately as possible, and the outer casing 12 of the mold positioned about the reinforcing element with its lower end seating in the channel 1% of the base. The positioning of the outer casing in this manner is facilitated by moving the clamp bar :23 to the lower end of the rods 21 and 2'2-.and by engaging the hook 25 with the co-acting bracket 19.
After the outer casing is in place, the top member of the mold is'a.pplied, care being taken that its flange '28 seats in the upper end of the core and that the upper ring of the reinforcing element engages between the fingers-of the various arms. When the upper member has been applied in this manner, the hook 25 is released to permit expanding of the upper end of the outer casing and the clamp bar 23 is drawn upward as far as possible to expand the mold casing and bring its lower edge portion into engagement with theoiiter face'of the channel 14 and its upper edge portion into engagement with the flange 31 of the upper mold member. Under these' conditions, all parts of the mold are rigidly locked together and the semi-liquid concrete mixture may be safely poured into the mold, the spout portion 30 of the upper member directing the liquid mass between the core and outer wallof the mold and the cap portion 27, preventing any loss of the concrete by its passage into the core.
After the concrete has partially hardened or set, the upper mold member may be removed to permit finishing or smoothing oil of the upper end of the-pipe section and after'tlie concrete has fully hardened or set, the mold may be disassembled and removed.
This is readily accomplished by removing the base 10 from the core and outer casing of the mold by lifting the remainder of the mold away from it and by theninoving the clamp bar 23 still higher upon the rods 21 adapted to core, because of its own resiliency will con-' tract and the pipe.
Having thus described the invention, what permit its ready withdrawal from is claimed as new'is:
. 1. A concrete-mold including an eXpansible outer casing, a core, a base provided with a circular channel in its upper face to seat the lower ends of the casing and core,
and a member engaging the opposite ends of the core and casing to support them in spa ccd relation, said member including centering means for a reinforcing member be disposed between the casing and core.
2. A pipe mold comprising an expansible outer casing, a core, a base member seating the casing and core, a conical cap formed with a flange disposed to engage the end of the corereinote from the base, arms extending from said cap, a spout nember supported by said arms I and engaging the outer casing, and spaced lugs formed on said arms and adapted to receive a reinforcing mem-- her when the latter is disposed between the core and casin 3; A pipe mold including a base formed with an annular channel in its upper face, an upper mold member including an inner cap portion and anouter funnel portion having depending concentric flanges, a core adapted to seatat its lower end in the channel of the base and engaged at its upper end about the flange of the cap portion, a resilient outer casing having overlapping edges adapted to seat at its lower end in the channel of the base member and to engage at its upper endwithin the flange of the funnel portion of the upper member, means for drawing the overlapping edges of said member into still further overlapping position and securing them in such position to permit positioning FREDERICK ii.
