I APPARATUS FOR FORMING BEADS 0N. CAST IRON PIPE.
. showing my invention in Application filed December 1, 1904.
To a/ZZ whom it may concern.-
Be it known that I, CHARLES N. CHURCH, a citizen of the United States, residing at Burlington, in the county of Burlington and State of New Jersey, have invented certain new and useful Improvements in Apparatus for Forming Beads on Cast-Iron Pipe, of which the following is a specification.
This invention relates to apparatus for forming beads upon cast pipe and the object is to provide an improved bead-ring pattern which may be readily withdrawn from the mold after the head is formed in the sand without removing the flask and mold from the chill, thus obviating the causing of an uneven pipe at the head end and the escape of metal between the flask and chill, the improved device being simple in construction and automatic in its action.
With the above object in View the invention consists in the novel features of construction hereinafter fully described, particularly pointed out in the claims, and clearl illustrated by the accompanying drawings, in which igure 1 is a longitudinal sectional view through the flask, pattern, and bead-ring, use; Fig. 2, a similar view showing the position of the parts after the bead is formed and the bead ring pattern anu main pattern partially withdrawn; Fig. 3, a top plan of the disk to which the headring sections are attached; Fig. 4, similar View with the bead-ring sections attached to the disk. Fig. 5 is a view illustrating one of the bead-ring sections of one set in side elevation; Fig. (i, a similar view same in rear elevation, and Fig. 7 vation of one of the beadring sections oi the other set.
, Referring now more of the pattern, thus holding the plate, main pattern, and plug'rigidly together. The
oose on rod 6 is a disk 9, provided with a sleeve 9 to hold it at right angles to the rod,
Specification of illustrating the l a rear 010- particularly ,to the drawings, ldesignates the flask; 2, the mold BU :tLlN TfTON, .NflGlV J rill.

therefrom a number the upperportrons 11 and extending inwardly of radial slots lOreceive of the stems of the bead-secions A and B. These be: ctions are \rcdg tain number, A, with the I wedge .uppern'msi and an 1 1 I do tnesmaller end r said sections bein l formed with lugs l3, projecting above and he low the disk, so as to prevent independent i longitudinal n'iovenient oi the sections with l respect to the disk, but to permit rocking l movement of said bead-sections, the adja cent portions H of the disk'upon which the ugs bear being rounded, as illustrated in Fi s. 1 and 2. The other ti oi bead-seel 2: i V l tions have lugs 15, which are spaced iron'r other and disposed and lower sides may be an independent vertical movement of these sections relati to the disk. These sections are also arranged to root: or .sw' or from the center of the m-sin the adjacent portiomoi the dish living rounded l, tp permit such movement The head- I trons pro ect hetween end oi {no out illr luv-m1 main pattern and the ping beyond the all i of the l'ormer and rest upon the chill when in i position to form the bend in the mold. Both in portions exopr-nin sets oi lunnl-seclions have ste tending downwardly into the 1 ol the plug and i fol-riled with earn portions, the l cums l6 oi the soc-trons A being med at a ddlerent angle or plane from the earns 37 of l the s rtious ll. llug 7 is l'ormed at its lower end with :1 web or operating portimi in, which by our igeinent with the eanr-suriaces oi the stems is adapted to ellect the rocking g movement thereof on the dish and the in- 1 ward movement of the head-sections in the l manner to be lull v described. The operation of my machine is as lollows:
After the head is formed in the sand and the the mold readr for the witlnlrawal oi the pattern the eyeholl (j is drawn outward, cerrying with it the plugT. the main pallerrrund the plate at the upper end thereof. is I l plug moves ouluurd the Wei) or operating 1 portion it; engages lll'. i the cam portions 16 'haped, a cerwedge uppermost,
upon the upper oi the disk, whereby there of the sections A, swinging or rocking said sections on the disk in which they are hung and drawing the sections toward the center oi the pattern. A further movement of the pattern causes said web to engage the cam portions 17 the sections B, ell'eeting the swinging thereof inward toward the con ter of the pattern wi thin the w all of the mol (1. During the continued upward movement of the plug the sections A and the pattern move upward, the spaced lugs of said sections permitting this movement of the sections relative to the disk. While sections A are being withdrawn from the sand inward movement of the sections B is prevented by the straight wall 19 of the plug; but when the withdrawal of the sections A has been or l'ected the straight wall. has moved tar enough to permit the inward movement of the sections B. The sections A and B having been withdrawn inwardly sufiicientl y to prevent the scraping or scratching of the wall, oi the main part of the mold, as per Fig. 2, a further movement ofiects the removal of the pattern, &c., from the flask without injury to the mold. As the pattern. is lowered into the flask it is centered by the plug, and the bead-sections are automatically returned to their place by engaging the upper face of the chill.
I have provided the sections A or B, or both, with an enlargement 20 of the stem below the bead-sections, forming a ring of projections which by either entering the chill-open- 'ing centers the plug and other parts, or
should t e pattern be lowered to one side far enough for one or more of these projections to rest upon the chill the outside edge of the beadsections will be held sulliciently high above the chilld ace through the medium of the stems 7, lugs 13 and 15, and the disk to prevent jamming of said edge of the bead-sections in tapered opening of the chill.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent ol the United States, is I 1. In a device for molding beads of cast pipe, the combination with the main pipe-' pattern, of a bead-ring comprising a plurality of bead-sections arranged to swing therein and formed with cam portions and operating means for cooperating with said cam portions to swing said sections inwardly from the head-mold after the latter has been formed.
2. in a device for molding beads on cast pipe, the combination with the main pipepattern, or" a bead-ring comprisin sets of alternating brad-sections, arranged to swing into and out of the pipe-pattern and formed with cam portions, and means cooperating with said. cam portions to swing said sections i inwardly from the bead-mold after the latter has been formed, said cam portions and operating means being so constructed and arranged as to effect the swinging of said sections in sets.
3. In a device for molding beads on cast pipe, the combination with the main pipepattern, of a bead-ring comprising two sets of bead-sections having cam portions, a plug having operatin means for engaging said cam portions an effecting the withdrawal of the bead-sections in sets from the bead-mold after the latter has been formed, and means for e flecting the movement of the plug.
4. In a device for molding beads on cast pipe, the combination with the main pipepattcrn, of a'disk in said pattern, a bead ring comprising a plurality of" bead-sections, mounted to swing in said disk, and formed with cam portions, a plug below said disk having operating portions adapted'to engage the cam portions and effect the inward movement of the bead-sections, from the bead mold, and means for efl ecting the movement of the plug.
5. In a device for molding beads on cast pipe, the combination with the main pipepattern, of a'disk in said attern, a bead-ring comprising a plurality o bead-sections having stems mounted to rock in the disk and downwardly-extending cam portions, a plug below the disk having slots to receive said cam portions and an operating portion to engage the cam portions and eii'ect the rocking of said bead-sections to withdraw them from the bead-mold after the latter has been formed, and means for efiecting'the movement of said plug.
6. In a device for.molding beads on east pipe, a flask, a chill-plate having a central opening, a main pipe-pattern, a plug carried thereby fitting in said opening of the chillplate, a bead-ring comprising a plurality of bead-sections, an enlargement on said seetions forming a ring on the under side thereof
