'7 Claims. (01. 20-1-17) This invention relates to improvements in dies bore which, is enlarged intermediate its ends to for extrusion presses and the like, and especially form a horizontal extrusion chamber 2 connected for presses for applying insulation or lead sheathto the interior of the cylinder B by one ormor'e ing upon wire or electric cable. I, passages 3 connecting with a supply chamber 4 5 In such devicesthe wire to be coveredipasses expanding upwardly to substantially the same 5 through a tubular core and a die, which are relasize as the interior of the cylinder B. A tubular tively spaced for the passage of the coating macore 5 is fitted in one endof the die block ibore 'terial therebetween. Usually the thickness 'ofthe and extends through the horizontal extrusion coating has been determined by horizontal adchamber 2 into proximity with the inner .face of justment of boththe core and die, respectively, a die 6 carried by a die ring 7 suitably secured 10 the one for coarse and the other for final adjustin a recess or enlargement formed in the bore at ments. Insome instances, the die has alsobeen the opposite end of the die block, and beyond the adjusted vertically by separate adjustingmeans extrusion chamber 2. Theends of. the die block to prevent eccentric application of "the coating bore are closed, when the parts are assembled loand to equalize the flow above and below the wire for operation, by tubular adjusting screws 8 and or cable; This latter adjustment has not only 'Q'threaded into the, die block and bearing, reincreased the expense of the press materially by spectively, against the outer ends of the die 6 necessitating the use of a'larger die block, but and core 5. r t 1 1 the adjustment is complicated and requires skill In accordance with the present invention, the

The top of In operation, the wire or cable to be covered the reception of the lower end of a cylinder B, 5, die 6, and out through tubular adjustment which acts as a container for the lead or other screw 8, the lead or other coating material being material to be extruded by movement of a plunger extruded thereon through the space between core C downward through cylinder B. 5 and die 6 under pressure of plunger C, with relative positions of the core 5 and die 6. The core 5 is adjusted through movement of tubular adjustment screw 9 to give approximately the desired thickness of coating desired, and any slight adjustments necessary to correct the thickness of coating at the top and bottom are taken care of by adjusting the die 6 in the die ring 7 through operation of tubular adjusting screw 8.
Due to the fact that the requisite horizontal and vertical adjustments of the die 6 are relatively slight, the angle of inclination of bore a in die ring 7 will not be large and may advantageously be substantially eight degrees to the true axis, though this may be varied according to the particular press and its requirements.
This die can be used in any standard lead press and the die blocks in general use may be readily and cheaply fitted to use the die construction of this invention.
It will be understood that modifications may be made within the invention as defined by the claims.
What is claimed is:
1. In an extrusion press, the combination with a die block and an adjustable core, of a die ring mounted in the die block and having a bore inclined vertically to the axis of the die ring, and an adjustable die having its exterior shaped to fit the die ring bore, whereby the die is adjusted vertically by its longitudinal movement.
2. A die comprising a die ring having a bore inclined vertically to the axis thereof, and an adjustable die having its exterior shaped to fit the die ring bore, whereby the die is adjusted vertically by its longitudinal movement.
3. A die comprising a die ring having a passage therethrough inclined vertically to the axis of the die ring, and an adjustable die having its exterior shaped to fit the die ring passage, whereby the die is adjusted vertically by its 1ongitudinal movement.
4. In an extrusion press, the combination with v a die block and an adjustable core, of a die ring fitted in said die block and having a passage therethrough inclined vertically to the axis of the die ring, and an adjustable die having its exterior shaped to fit said die ring passage whereby the die is adjusted vertically by its longitudinal movement.
5. A die comprising a die ring having a bore inclined vertically to the axis thereof, an adjustable die having its exterior shaped to fit the die ring bore, whereby the die is adjusted vertically by its longitudinal movement, and means for preventing relative rotation between the die ring and the die.
6. In an extrusion press, the combination with a die block and an adjustable core, of a die ring mounted in the die block and having a bore inclined vertically to the axis of the die ring, an adjustable die having its exterior shaped to fit the die ring bore, whereby the die is adjusted vertically by its longitudinal movement, and means for preventing relative rotation between the die ring and die.
7. An extrusion press having a die block, an adjustable core in the die block, and a die mounted in said die block and adjustable longitudinally thereof toward and from said core, the die mounting in said block having a longitudinal passage for the die with its die engaging surface inclined vertically to the axis of the die and said die having a surface shaped to fit said inclined surface, whereby a vertical adjustment of the die is secured by the longitudinal movement thereof.
