TUBE-MAKING MACHINE.
Specification of Letters Patent. Patented Mar, 28, 1916 Application filed March 13, 1915. Serial No. 14,112.
useful Improvements in Tube-Making Machines, of which the following is'a speci fication.
Although my invention is illustrated as embodied in a machine which is "adapted for forming a tube of lead around a tube of hose it is to be understood that it is without regard to whether such tubing is formed around a tube of hose or a tube of any other character and also without regard to the metal employed.
One object of my invention is to provide an improved construction of tube making machine having a plurality of chambers or passage-ways from which the molten or plastic metal, as heated lead, may be supplied alternately to the die chamber of the machine.
A further object of my invention is to provide novel and efficient means for causing the alternate passage of the molten metal from the said chambers or passageways to the die chamber of the machine.
A still further object ofmy-invention is to provide a construction having means whereby when pressure is exerted upon the molten or plastic metal or other suitable material in one of the said chambers or passage-ways to force the same into the die chamber the other chamber or passage-way is automatically closed.
Other objects and advantages of my invention will be referred to and. pointed out in the detailed description of my invention which follows or will be apparent from such description.
In the accompanying drawings to which reference should be had in order that my invention may be more readily understood I have illustrated one form of a convenient embodiment of the same but it will be understood that changes in the details of construction may be made within the scopeof the claims without departing from my 1nivention. v
In the drawings :Figure 1 is a vertical longitudinal sectional view of a port10fi of a tube forming machine embodying my 1nvention; Fig. 2 is a view partly in top plan and partly in horizontal section, taken on the line 2-2 of Fig. 1; and Fig. 3 is a front end view of the same.
Referring to the drawings, 1 designates a die chamber block supported upon any suitable support, such as the conventionally shown support 2. The block 1 is provided.
with a die chamber 3 in which is situated a male die or core-tube 4. The male die or core-tube 4 is supported in a screw-threaded sleeve 5 having screw-threaded connection with the interior of the die chamber. The male die 4 is retained within the sleeve 5 bymeans of a tubular plug 7. The forward end of the male die 5 cooperates with a female die 9 supported in the die carrier 10, the latter in turn being supported within and by the sleeve 1O supported within and by the tubular nut 11 which is screwed into the tubular support 12 which is adapted to be inserted into and removed from a recess 13 formed in the forward end of the die block 1 in alinement with the die chamher 3.
It will be understood that the molten or plastic metal, as heated lead, within the die chamber 3, may be cooled in any suitable manner.
The molten or plastic metal is discharged into the die chamber 3 by means of a pas sage-way 15 the upper end of which is flared as indicated in Fig. 1 of the drawings. The molten or plastic metal, as heated lead, is discharged into the passage-way 15 from the supply chambers or passageways 16 and 17 which are provided in the block 18 which is supported upon the top of the die cham ber block 1 and secured in such position by means of bolts 19 which project upwardly from the support 2 and the upper ends of which extend through slots 20 formed in flanges 21 upon the opposite sides of the block 18. These chambers or passage-ways 16 are arranged angularly with respect to each other and intersect, as is clearly shown in Fig. 1 of the drawings. At their region of intersection they merge into each other and the flared upper end part of the passage-way 15 in effect constitutes a continuaand are continuations of the sides 24 and 25 respectively of the chambers or passageways 16 and 17. As illustrated these passage-ways are rectangular in cross section but it will be understood that they may be of other shapes, as, for instance, square.
26 designates an oscillatable member pivoted at 27 to the block 18 in the angle between the chambers or passage- ways 16 and 17. The oscillatable-member 26 is loosely pivoted upon the pivot 27 and tends to occupy a normally depending vertical position intermediate the lower end portions of the chambers or passageways 16 and 17 in alinement with the delivery passage-way 15 in the block 1. The upper end of the member 26 is curved, as indicated at 28, and is seated within a correspondingly curved seat 29 formed in the block 18 intermediate the chambers or passage- ways 16 and 17 The lower end of the said oscillatable member 26 is beveled upon opposite sides or tapered as indicated at 30 and 31. The beveled side 30 is adapted to contact with the sides 22 and 24 while the beveled side 31 is adapted to contact with the sides 23 and 25, as illustrated in Fig. 1 of the drawings.
The width of the member 26 is .equal to that of the width of the chambers or passage-ways l6 and 17 so that when the said member is in the position illustrated, for instance, in Fig. 1 of the drawings, the lower end of the chamber or passage-way 17 is closed.
In order to force the molten or plastic metal, as heated lead, from thechambers or passage- ways 16 and 17, I have provided the plungers 32 and 33 the former operating in the chamber or passage-way 16 and the latter in the chamber or passage-way 17. These plungers may be operated by any suitable known mechanism, but as such mechanism does not constitute a part of my invention it is not illustrated.
In Fig. 1 of the drawings I have illustrated the chamber or passage-way 15 as containing molten or plastic metal which is being forced out through the passage-way 15 by means of the plunger 32. The pressure of the plunger 32 operates through the molten or plastic and more or less mobile metal within the chamber or passage-way 16 upon the pivoted oscillatable closing member 26 to force the same into the position shown in said Fig. 1 of the drawings in which the lower end of the chamber 17 is closed. The plunger 33 is'shown in position removed from the chamber 17. This permits the supplying of molten or plastic metal to the chamber 17 during the time that the plunger 32 is forcing the metal from the chamber 16. As soon, however, as the plunger 32 has reached the limit of its forward stroke and is thereafter withdrawn the plunger 33 is placed in operation either automatically or otherwise and enters the chamber or passage-way 17. The pressure of the said plunger upon the top of the molten or plastic material in said chamber forces the pivoted oscillatableclosing mem ber 26 toward the right (having reference to Fig. 1 of the drawings) until the beveled or tapered side 30 upon the lower end thereof contacts with the sides 22 and 24 to close the chamber or passage-way 16 and open the passage-way 17 to permit the molten or plastic material to flow therefrom into and through the passage-way 15. This op-' ber 16 its upper end will fit closely against the portion of the seat 28 adjacent to the chamber or passage-way 17 and that its side 35 will be in alinement with the adjacent surface of the side wall of the said passage-way or chamber 17.
In order to partially cool the molten metal in the chambers 16 and 17 and also prevent the block 18 from becoming too hot, I have provided the angular passage-way 40 therein through which water or any other cooling fluid may be caused to flow and I have also provided the passage-Way 41 through which a cooling fluid may be Caused to flow,
I claim 1. In a tube making machine, the com bination of a block having two chambers or passage-ways therein for the reception of molten metal, said chambers or passageways intersecting each other, an cscillatable member pivotally supported upon a pivot secured in the said block in the angle between the said chambersQr passage-ways, the upper end of the said pivoted member being curved and being seated against the correspondingly curved bottom of a recess 'in the said block, the said pivot extending through said recess, and the lower end of the said pivoted'device being beveled upon opposte sides. the said bevels being adapted to contact with the opposing inclined sides of the chambers or passage-Ways at their region of intersection.
2. In a tube'making machine, the combination of a -die chamber block having a passage-way therein leading to the die chamber. a block having a pluralityof angularly related chambers or passage-ways therein which passage-ways intersect each other and merge into the upper end of the passage-way in the die chamber block and the said block also having a recess therein in the angle between the said passage-ways or chambers, an oscillatable device having pivotal connection with the second-named block, the pivoted end of said device being situated in said recess and contacting with the bottom thereof, means for exerting pressure upon the metal within the said chambers or passage-ways for causing the same to be discharged therefrom into the passage- Way in the die chamber block, said oscillatable device acting automatically when pressure is exerted upon the metal in one of saidangularly related chambers or passage-Ways to close the other of said chambers-or passage-ways.
3. In a tube making machine, the combination of a block having two chambers or passage-ways therein for. the reception of 'molten metal, said chambers or passageways intersecting each other and said block also having a recess with a curved bottom in the angle between said chambers, said recess opening into said chambers, a pivot supported on said block and extending throughusaid recess, an oscillatable member pivotally supported upon said pivot, the pivoted end of said member being curved and being seated against the curved bottom of said recess and the opposite sides of said oscillatable member being adapted to contact alternately with the opposite side edges of said recess and the lower end of said pivoted device being beveled upon opposite sides the saidbevels being adapted to contact with the opposing inclined sides of the said chambers or passage-ways at their region of intersection, substantially as described.
In testimony that I claim the foregoing as my invention I have hereunto signed my name this 9th day of March, A. D. 1915.
