any onwf e-.Sries'efpellets 42,.:hzwing' a central perforation of appropriate size to co-operate with the desired core 41, may be supported in the desired vertical position by means of supporting lugs 48 on frame l0, each pallet being preferably provided in its upper surface with an annular seat 49 into which the lower end of the sectional mold 50 is seated,

For the purpose of holding the upper ends of the iii-olds or 50 in properly centralized position, I provide pairs of plates 51, 51`

, a diameter slightly in excess of the diameter of the largest moldv which is to be used and, vin order that this perforation may be centralized with relation to the axis of any particular core which is to be used, 'I provide the section 55 -withfslots 57 through which the retaining bolts 58 pass intol the main frame 10. YThe section 55 is provided with 'a' chain 60 which may be utilized to support the segments 12 in the position shown in Fig.

. 2 when-said segments are thrown back out of the way of `that portion lof the apparatus l which is utiliZed'in the formation of straight pipe sections. v

In order to produce Ys, I provide a fitting or insert 71 (Fig. 7) 'which may be set in the lower end of a straight pipe mold 50,

vsaid insert being suitably' perforated in order to slip over a core 41. The upper face'72 of the insert 71 is appropriately formed,

as indicated in Fig. 7. to produce a beveled end of the pipe 'casting 73 of such form that said casting may be cemented upon the side of a straight pipe which has been suitably cut away to lreceive it, so as to form :l` Y. v

Similarly, as shown in Fig` 8, I provide an insert 76 having a crotch-like upper end 77 forl use vin forming the stem of a T or right angled Y. i i

I claim as my invention:

vl. A pipe vmolding machine comprising a main fra-me, a core carrier pivotally supported in said main frame, means lfor swinging said core carrier inthe frame,-compris c ing a segmental gear on 'the carrier and a pinionmeshing with said gear, a curved i core.-means'for detachably connecting said curved core` to the carrier concentric with ythe'axis of thecarri'er, a swinging mold support co-axial-with the core carrier and means for holding said mold'support in different positions ofv angular adjustment. Y

support co-axial with thecore carrier and v means for holding said moldl support in dif ferent positions of angular adjustment.

3. A pipe molding machine comprising a main frame, a core carrier pivotally supported in said main frame', a curved core, means for. detachably connecting said curved core to the carrier concentric with the axis of the -'carrier, aswinging mold support co-axial with the core carrier and means for holding said mold support in dii'erentpositions of angular adjustment. l

4. A pipe forming machine comprising -a main body, a-curved core, means for supporting said curved core, a pivoted mold sup-- port having its axis concentric with the core, and means for holding said mold support in different positions ofangular adjustment.

5. Pipe forming machine comprising a main framefa curved core carried by saidI main frame, a mold support swinging about the axis of the curvedcore, a cup-like. mold carrier carried by said mold support yand having Y a perforation through which the core is projected and means for holding the` mold support in different lar adjustment.

6. A pipe forming machine comprising a 'positions ofangumain frame, a vsegmental 'core carrier journaled on the mainframe, a segmental= core carried'by said carrier, a mold carrier swinging about the axis of the core carrier, a cup-like mold receiver carried bythe mold carrier yand providedk withl a perforation through which the core is projected, and means for holding the ycore carrier in different positions of angular adjustment, and means for holding the mold carrier in different positions of angular adjustment.

7. A pipe forming machine comprising a:

main frame, VVa segmental' core carrier journaled on the main frame, a segmental core carried by said carrier, a mold carrier swinging about the axis of the corecarrier,

and means for holding the core carrierinN different positions of angular adjustment,

and means for holdingy the mold` carrier in different positions of angular adjustment.

8. In a pipe forming machine the combination with a core, of a tubular mold, means for holding said mold inl co-active relationship with the coreyand aperforated insert sleeved into the mold'and over the core and provided with an inclined upper face.v

9; In a pipe forming machine the combi- 1 nation of a core carrier, a work table hav- :ing a mold receiving perforation, means for holding said table in various positions of` for holdingdsaid table in various positionsV of lateral adjustment upon the main frame.
