Be it known that I, 'rro l?. HEER, acit,Y
izenot the United States, residing at' Ontarlo, 1n thecounty of 'San Bernardino ,and
'Y 5 State ot California, have inventedy new and use'tul improvements in Pipe Molds, 0f which the following is' a speciiication.
My invention relates to pipe molds, and a purpose of my invention is the provision of a -pipe mold of that'character in which either the casing orcore or both are slowly rotated during the tamping operation, my
invention consistingv in forming the core with a liner which is' removable tofallow of the substitution of anew liner when the circular contour thereby effecting the forminfr oit Va pipe of uniform thickness. l will' describe one form of pipe mold and two forms, of cores all embodying my invention and will then point out the` novel features thereof in claims.
3D vation.
In the accompanying drawings,
Figure 1A is aviewshowing in vertical section one torni' otmoldembodying my invention with a portion of the core in ele- Fig.r 2 is a top plan view of the mold shown in Fig. 1.
Figs...3 and 4 are transverse sectional views taken onthe lines33 and4-4l, respectively. of Fig. 1.
Fig. 5 is a fragmentary sectional view showing the construction ot the. oints of the core cylinder and liner. i
Fig. G is a fragmentary-sectional view showing a modiied means for securing the core vto the bell ring. f
Similar reference characters refer to sirnilar parts in each ot the several views.
Referring specifically-to the drawings, my inverltifnt in its present embodiment, comprises a turntable T adaptedto be supported for rotational movement by any suitableV means such as that shown in'my Patent No. 1,330,760, issued February 10, 1920. A pin 15 is threadedly fitted within the table T and arranged axially thereoic to form centeringr means for a bell ring B, the latter being of the contour shown in Fig. 1.
The pipe mold per se comprises a casing K of tubular :torm and having an outwardly flared lower endto co-operate with the bell molding a pipe *ring in: forniingl the joint portion...-*otrthe` 'i l pipe as'rwill be'understood.k Handleslc are fixed at. `diametrically opposite points t-o the casing for facilitating the vapplication or removal of the Vsame tothe table T.V lThis casingl is adapted to beiixedly secured upon the-turntable T by means of clamping' bars 16- having upstanding terminal exten# sions leadapted vto contact with-the lower end of the casing K .and securely; hold the, same in engagement with'the bell ring B.' The bars'f-l are secured in clamping position by means of screwsv 17 mounted in the .table'Tand extending' throughslots formed lNithin the casingl and supported upon the bell ring B K core being designated generally Vat C andin-` 'cluding an inner 4cylinder 18 and an outer cylinder-or liner 19. The'inner cylinder 18 is liormedyby rollingl a Vsheet ot metal intocylindrical form ands'ecuringjthe vver,-
"tical vedges Vthereoffby weldingias vindicated at 2O in Fina 5. In formingr this cylinder,
Vrings 21ers employedwhich. as clearly .shown in Fig. 1, are arranged adjacent the opposite ends of. the cylinder and secured therein by lmeans of bolts 22. Theserings are formed fromangle kbars which can be i rolled to term a perfectcircle so that when inserted into thecylinder and secured therew to they hold the cylinder in true cylindrical formation. l i
i r`Ilhe outer cylinder' or liner19 is arranged v*inssurrounding relation with-respect to the rinner ,cylinder andthe bolts 22 are utilizedY for securing the two together while other bolts-22aV are extended through the cylinders adjacent their split portions for securing the outer cylinderin contiguous relation with respect tothe inner cylinder. As' clearly shown in Figs. 1 and. all outer boltsv are provided ,with countersunk heads soas to provide a smooth surtacefor the core. As the outer cylinderis held in contiguous 'relation with the finner cylinder, it will be clear that the outer cylinder also occupies true cylindrical form so that the core as a unit vwhen in position .within theV casing K will co-operatewith the latter in of uniform internal diameter. Y
As shown in Figs. `1 and 2, the innercylinder 18 is provided witha brace bar 23 to which threadedrods 24`are connected7 andY these rods are adapted to be associated with "in the bars. alias clearly shown in Fig.' 1.,v I
is the core ot the mold, such suitable elevating means (not shown) for' movingv the core as a unit into and out of the casing K. For preventing displacement of the core from the bell ring'B, a positioning pin 25 is threadedly iitted Within the Y tion the concrete contained between the core C and the casing K is taniped in the usual manner in effecting a formation et" the pipe.
Continued use ot the mold obviously causes the Wearing away of the core C thus necessitating the renewal oi' the core at frequent intervals.y The labor and expenseattendant these substitutions is eliminated by the employment of the core C constructed in the manner previously described, as it Will be manifest that all Wear takes `place on the surface oi' the liner 19, and when this liner becomes unduly Wornitecan be readily removed from the inner` cylinder 18 and a new oner substituted.
` ln Fig. 6 l have shown a modified means for removably associating vthe core C With the bell ring B. ln this embodiment, the end'o'f the cylinder 18 is provided adjacent its lower end with a bar 28 having upturned ends'ivhich are secured to the cylinder by bolts 29. This bar 2S carries depending pins 30 which are adapted to engage Within the'recesses formed in the upper vsid-e of the bell ringv l?, the arrangement 'of the pins being such that when the bell ring is rotated correspondingmovement is imparted to the core.
.although have herein shown and .described only one term ot pipe mold embodying my invention, it is to be understood that various changes and modifications may beA nade herein Without departing lfrom the spirit of the invention and the spirit and scope ot the appended claims.`
That l claim is: g y
1. .fi pipe mold comprising a turntable, a casing sustained on the turntable, a bell ring remerably associated `with the table, clamping bars adjustable on the turntable and eooperating with the bell ring for clamping the casing' on the turntable, and a core sustained on the bell ring' Aand'comprising an inner cylinder yand an outer cylinder removably associated with the inner cylinder.
2. A. pipe mold comprising a turntable, a bell ring sustained on the turntable, a centering pin carried by the turntable and engaging the bell ring for centering the latter on theturntable, acasing surroundingthe bell ring, clamping bars adjustable on the turntable and eo-operatingwvith the bell ring oriixedly securing the casing to the turntable, a core .sustained on the bell ring, a block carried by the core, and a pin on the bell ring and engaging said block for centering the core on the bell ring.
ln a pipemold, a core comprising an inner 'split cylinder, rings Within the cylinder Vfor maintaining the latter in true cylindrical formation, an exterior liner received on the cylinder and means extending through the cylinder, liner, and rings for securing' thev same together.
11. pipe mold comprising` a turntable, a bell ring sustained on the'turntable, a eentering pin carried by the turntable and engaging t-hebell ring Ator centering the latter lon the turntable, a casing surrounding the bell ring, means for tixedly securing the casing to the turntable, a core sustained on the bell ring', a block carried by the core, and ay pin on the bell ring and engaging said blockfor centering the core on the bell ring.
5. A pipe mold comprising a turntable, a casing sustained on the turntable, a bell ring1 removably associated With the table, means adjustable on the turntabler and cio-operating with the bell ring1 for clamping' the easing on the turntable, and a core sustained on the bell ring` and comprising an inner cylinder andan outer cylinder removably associate( with the inner cylinder. y
6. pipe mold comprising a turntable, a bellring sustained on the tiu'ntable, a centering member carried bythe turntable and cngaging Vthe bell ring for centering the latter on the turntable, a casing surrounding the bell ring, means tor ixedly'securing the casing to the turntable, a core sustained on the` bell ring, a4 member carried by the core, and a member on the bell ring Vand en the core 'carried member tor centering the core on the bell ring.
