Y., A CORPORATION OF 'NEW YORIK METHOD OF AND APPARATUS FOR TREATING MOVING MATTER Application filed May 31, 1927, Serial No. 195,396. Renewed August 7, 1929.
This invention relates to a method of and apparatus for treating moving matter, and more particularly to a method of and apparatus for quenching matter being extruded.
In the extrusion of certain kinds of ma terial, it has been found that an improved product is obtained when the material is quenched immediately after it leaves the extruding die. Thus, in the extrusion of lead alloy cable sheathing, it has been discovered that an improved product is produced when the sheathing is quenched immediately after it is extruded.
The principal object of the present invention is to provide an improved, simple and efficient method of and apparatus for treating moving matter.
Although the invention is obviously capable of various applications, it may be employed to particular advantage in conjunction with the method of and apparatus for continuously extruding lead cable sheathing disclosed in Patent No. 1,720,759, issued July 16, 1929, to John Edson Boynton.
In accordance with apreferred embodiment of the present invention, the cable sheathing, immediately after leaving the extruding die, is advanced through a chamber of gradually increasing cross section wherein it is subjected to a cooling medium applied directly thereto in such manner that an aspiratory action is provided whereby leakage of the cooling medium is prevented. Although various kinds of cooling mediums may be employed, water at room temperature has proven very satisfactory. Means is provided for causin the condensation of the steam produced y the water contacting with the extruded material. The used water and the condensed steam are discharged through suit- .able conduits provided for that purpose.
Other featuresand advantages of the invention will become apparent from the following detailed description, reference being had to the accompanying drawing, wherein Fig. 1 is a longitudinal vertical section of a quenching apparatus embodying the features of the invention and by means of which the improved method of quenching extruded matter may be practiced, and
Fig. 2 is an end elevational view of the apparatus shown in Fig. 1.
It is believed that the invention will be clearly understood from the following detailed description of a preferred embodiment thereof. As shown in the accompanying drawing, the reference numeral 10 designates a portion of a hollow block within which is supported a core tube 11 designed and arranged so as to provide an annular passage 12 for the matter to be extruded. The passage 12 tapers toward the discharge end thereof and communicates with an extruding die 14 threaded or otherwise secured within the hollow block 10. The reference numeral 15 designates a cable which is advanced through the core tube 11 and the, die 14 by any suitable means (not shown). As the cable passes through the extruding die, a sheathing of lead 16 is extruded thereon. For
a detailed description of the construction and operation of the extruding apparatus, reference is had to Patent No. 1,720,759 above referred to.
In accordance with a feature of the present invention, the extruded sheathing 16, immediately after leaving the die 14, is advanced through a quenching device designated gen-' erally by the reference numeral 18. The quenching device is removably supported by means of brackets 19, 19 secured to the block 10, and comprises an outer cylindrical casing 20 having a concentric inner cylindrical casing 21 threaded at one end thereof and a cup-shaped member 22 threaded at the opposite end thereof. Secured to the forward end of the inner cylindrical casing is a sleeve 24 having a downwardly projecting discharge tube 25 secured thereto or formed integral therewith. A cap 27 threaded upon the forward end of the sleeve 24 is provided with a central aperture 28 for the passage of the sheathed cable therethrough.
As shown in Fig. 1, a reduced portion 30 of the inner cylindrical casing 21 is spaced from the outer casing 20 so as to provide an annular chamber 31 therebetween. The inner casing 21 and the sleeve 24 provide a continuous chamber 32 which communicates with the discharge tube 25.- The chamber 32 is in comturcs 38 and 39, respectively, for the passage of the sheathed cable therethrough. Formed in the members 22 and 37 is an annular compartment 40 which communicates with the chamber 32 through the aperture 38. Extending downwardly from the compartment 40 and communicating therewith is a drain pipe 41.
In the operation of the above described quenching apparatus, a cooling medium, preterably water at room temperature, is introduced under pressure into the forward end of the chamber 31 through one or more conduits 44 connected to a supply source through a main conduit 45. Due to the tapered construction of the chamber 31, the water attains a high velocity as it passes through the passage 34 into the chamber 32 after which the velocity is reduced due to the tapered construction of the chamber 32, which also producesan aspiratory action, thus preventing leakage of the water through the aperture 38.
Because of theannular shape of the passage 34, the water is directed equally around the sheath, completely submerging it and efiecting a quick and uniform cooling there-of.
Best results'are obtained when just enough water is used to completely fill the discharge tube 25. This prevents the entrance of air through the discharge, promotes a steady uniform flow through the chamber 32, and establishes the maximum aspiratory action.
Substantially all of the steam which may be produced by the water contacting with the heated extruded sheath is carried along by the water and discharged through the tube 25. That which escapes through the aperture 38 condenses in the compartment 40 and is discharged through the drain pipe 41.
Thus, the possibility of water or steam coming in contact with the extruding die is eliminated.
Although the invention as herein illustrated and described is particularly well adapted for quenching extruded cable sheathing, it should be understood that the novel features of the invention are capable of various other applications within the scope of the appended claims.
What is claimed is:
1 A method of treating moving material. which consists in subjecting the material to a fluid applied directly thereto with an aspiratory action.
2. A method of quenching material being extruded, which consists in subjecting the material to a cooling medium applied uniformly to the whole surface thereof with an aspiratory action.
