PROCEDE DE FABRICATION DE TUYAUX EN FER FORGE A AILETTES CIRCULAIRES.
La présente invention a pour objet un procédé et un dispositif de fabrioation de tuyaux en fer forgé à ailettes circulaires,
Deux dispositifs appropriés à la réalisation du procédé sont représentés au dessin annexé.
La Fig.I est une coupe transversale suivant la ligne C- D de la Fig.2 et
La Fig.2 est une coupe longitudinale suivant la ligne A -B de la Fig.I du premier exemple.
La Fig.3 est une coupe transversale suivant la ligne E- F de la Fig.4,et
La Fig. 4 est une vue de dessus du deuxième dispositif.
Dans l'exemple représenté par les Fig.I et 2,la partie

supérieure b du bâti ou corps de maintien en deux parties est articulée sur la partie inférieure a du bâti double au moyen d'un axe c,de sorte que la partie supérieure b peut être amenée dans la position indiquée en trait mixte, f est un oeil- leton destiné à recevoir un câble métallique portant un con- trepoids servant à équilibrer la partie supérieure b.Les par- ties a et b du bâti peuvent être chauffées à l'électricité,au gaz,à la vapeur à haute pression ou à l'eau chaude sous une haute pression.Après que la partie supérieure b du bâti dou- ble aété amenée à la position indiquée en trait mixte,on in- roduit des disques annulaires d dans les logements ménagés à cet effet dans la partie inférieure a,
puis on ramène dans sa position primitive la partie supérieure b pourvue d'évidements correspondants,de façon que les disques annulaires d se trouvent entièrement noyés dans la masse.on fait ensuite fonctionner le chauffage,Dès que la température nécessaire est atteinte, on introduit le corps tubulaire e,de sorte que tous les dis- ques annulaires d viennent s'appliquer sur ce corps tubulaire e.
On ramène ensuite la partie supérieure b dans sa position in- diquée en trait mixte.On retire le tuyau terminé comportant les ailettes circulaires,et on le met de côté pour le laisser refroidir;pendant le refroidissement,les disques annulaires d se frettent fortement sur le corps tubulaire e;
Dans les Fig.3 et 4,a est la partie inférieure et b la partie supérieure du bâti constitué par différentes lames maintenues au moyen de boulons filetés ;des anneaux d'écar-. tement servent à ménager l'intervalle nécessaire pour l'in- troduction des disques annulaires d.La partie supérieure b est articulée sur la partie inférieure a au moyen de l'axe c, ce qui permet d'amener cette partie supérieure b dans la po- sition indiquée en trait mixte. f est un oeilleton auquel peut être fixé un câble métallique avec contrepoids servant équi- librer la partie supérieure b, h sont des tuyaux à gaz.Des aju-

METHOD OF MANUFACTURING WROUGHT-IRON PIPES WITH CIRCULAR FINS.
The present invention relates to a method and a device for manufacturing wrought iron pipes with circular fins,
Two devices suitable for carrying out the process are shown in the accompanying drawing.
Fig. I is a cross section taken along the line C- D of Fig. 2 and
Fig.2 is a longitudinal section along the line A -B of Fig.I of the first example.
Fig. 3 is a cross section taken along the line E- F of Fig. 4, and
Fig. 4 is a top view of the second device.
In the example represented by Figs. I and 2, the part

upper part b of the frame or holding body in two parts is hinged to the lower part a of the double frame by means of an axis c, so that the upper part b can be brought into the position shown in phantom, f is a eye designed to receive a metallic cable carrying a counterweight serving to balance the upper part b. Parts a and b of the frame can be heated by electricity, gas, high pressure steam or hot water under high pressure.After the upper part b of the double frame has been brought to the position shown in phantom, annular discs d are inserted into the housings provided for this purpose in the lower part a ,
then the upper part b provided with corresponding recesses is brought back to its original position, so that the annular discs d are completely embedded in the mass. The heating is then operated, As soon as the necessary temperature is reached, the tubular body e, so that all the annular discs d come to rest on this tubular body e.
The upper part b is then brought back to its position shown in phantom. The finished pipe with the circular fins is removed, and it is put aside to let it cool; during cooling, the annular discs d shrink strongly on the tubular body e;
In Figs. 3 and 4, a is the lower part and b the upper part of the frame made up of different blades held by means of threaded bolts; spacer rings. The upper part b is articulated on the lower part a by means of the axis c, which makes it possible to bring this upper part b into the position indicated in phantom. f is an eyelet to which can be attached a metal cable with counterweight to balance the upper part b, h are gas pipes.
