The travelling crane 6 takes the cores 7 direct from the core-making shop 5 and deposits them in the moulds For thlSfPIlI'PQSGthG core must change its position from the honz ontaltothe vertical. Thisis done with the aid of acrane 8 in the shop 5, The'reverse processtakes place when the casting shop crane matter the castin of thepipes in the moulds 1,-extracts the ho lowiron spindles of the cores which always have to be used over again) from the moulds "1 and deposits them on the'core waggon'9. The casting 'of t he pipes is effected by means of'the travelling Waggon; so that there are always three wag cranelO and the casting pan 11. In the coremaking shop 5there is thetwo-storied dryn'ig chainber 12a, 12b At eachsideandin the drying chamber there is located a core g(;}ons 9,{ 9a, and 9?) simultaneously in use.
roups of core waggonsand drying chamcorresponding to the number of mould fralrie's I; 4,"in the casting shop 2,-a're' arranged'behind each other in the shop '5. V The i gore waggons 9, 95, are conveyed verticallyjon .lifting tables; 13, 13a; which are lifted and lowered in the embodiment shown in the drawings bytwo hydraulically driven pistons 20; QQa." flhecore waggons 9, 9a mega are v conveyed horizontally bya drawing'device 15 cable chain or "the like) driven by 'an electric winch 14 or by the cranefi. v I
- v ma process The core spindles are extracted from the p I finished castpipes by means of the crane 6,
I the winch 14,- 15 to thelifting table which is standing in a raised position. During this s time there are twocore-waggons9a, 96. in
the drying chamber. Thereufkii'i the litting A table 13a -is lowered and core-maker's 7 17 to one oftheflcore lathcs 16L- Here' the lift the core spindles by means of the crane core spindles are wound roend with straw ropes or the like; after whicha clay-like core mass appliedthereto; The core is then taken from the lathe '16 andlaid again on, theccor'e' Waggon-L When all thecores,
whichlthis Waggon can take, have ha-dth'eir first:zrpplicatiou'ofclay, the core Waggon is drawninto-the drying chann'ber with aid t thegwir eh 14?, 1a. The liftingitab'le a is now brought to such a height that the loaded core Waggon in the top or bottom storey of the drying chamber can be drawn out on to this lifting table. The cores now receive their second application which consists of a more sandy clay (smooth coat). After this has been done, the core waggon is pushed back by=the winch'M into the drying chain'- -bcrand the process is repeated with the next core aggon. After a thirdo eration on the lath'es viz. the application o the graphite, thecore Waggon does not return back to the core making shop but is, with the aid of the crane and using a cable rope or the like and loose rollers, withdrawn from the drying chamber and placed on the lifting table 13, from whererthe cores are-nowpassed. to the moulds l which have inthe meantime, been completed, the above being 'e fi'ected without the coi'eui'iakeis-bcinghindered in the preparation ofthecores by theremoval of finished "cores oiythe bringing back of the empty, core spiudlesifroni tlieicasting shop. 7 The cores and core spindles which a latter are always returning back tobe used 'agaii'r, thusltakethe shortest possible course f oin the core-'making'sho'p to-thecasting shop.
