METHOD OF AND MACHINE FOR 'EXTRUDING METAL To all whom it may concern: Be it known that I, DAVID L. SUMMEY, a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented'a new and useful Improved Method of and Machine for Extruding Metal;and I do hereby. declare the following, when taken in connection with the accompanying drawings' and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

method of, and machine for, extruding metal tubes, rods and the like, the object being to'produce extruded metal stock of superior quality and at a reduced cost.
With these ends in view my invention consists in the method and machine'to be hereinafter described and pointed out in the claims.
In carrying out my invention, Iemploy a horizontally arranged cylindricalcontainer'2 formed with a central, horizontal billet-chamber 3 open at both ends. As
shown, the billet-chamber 3 is circular, but its cross-sectional form may be varied as found expedient. Thesaid container 2 is as a also formed with a transverse passage shaped like an hour-glass, openat both ends and'intersecting the. said billet-chamber 3 midway the .length thereof and at a right angle thereto. This passage forms two conical centering-chambers 4 for the. reception, respectively, of the conical hold: ers 5 and '6 of the mandrel 7 and die 8.... i
In practicing my improvedmethod, a bil let 9, preferably heated and relatively long as compared with its diameter, is introduced into the billet-chamber 3 at a time when the said mandrel 7 and die 8 are entirely: retired therefrom. The billet is solid, andby the-term solid I refer to the condition of the billet which is sufiiciently rigid to retain its shape while being. introduced into the billet chamber and not to the shape or form of the billet which, if desired, might be perforated or-hollow. After the billet has been positioned in the said chamber, the mandrel and die are advanced the'reinto, and embedded and positioned in the billet the waist of which, .so .to speak, they enter. The billet is then subjected to pressure upon its opposite ends, causing the metal .comprising it to flowat a ri ht angle to its axial line around the mandre 7 and through the die 8 in the form of a tube.
pposite points by the two conical center.-
ing-chambers 4 already described. The said .rib 10 is registered, when. the container is with a corresponding internal in position, rib 11 centrally located within a cylindrical opening 13 adapted in diameter to receive the container 2'andformed in a main casting 14 resting upon bed-plates 15. The Opits work by means of. four'draft-rods '28 ,the auxiliary hydraulic cylinders 31, u i. "only effective when the water pressure is shown, in front-of one of the rams 16 after posite ends of the opening 13 are th i aded '23 are thus fixed in their relation to the main-casting" 14. Locking nuts 25, 26,
or the reception of bushing-like nuts 12 respectively'encircling the ends of the container and bearing against the opposite edges of its rib 10. These bushings prevent the container from movin in the main-casting but permit it to be ongitudinally adjusted therein.
For simultaneously subjecting the billet 9 to endwise pressure at both ends. in the chamber 3, I em loy two corres onding rams 16 operated y duplicate mec anisms located on the opposite sides of the mamcasting 14 but in line with each other and in line with the said chamber 3, each of these mechanisms constituting an arm of the machine when the same is viewed broadly as in Figs. 1 and-2.
Each ram 16 is-secured by a head 17 to a guide-block 18 traveling back and forth upon corresponding columns 19 passing horizontally through holes 20 in the maincasting 14 from the opposite sides of which they project for equal distances, being held against endwise movement in the holes 20 by their provision with nuts 21 bearing against the sides of the said casting. Each guide-block 18 is carried by a plunger 22 operated by a hydraulic cylinder'23 formed on opposite sides with sleeves 24 receiving the ends of the columns 19. The cylinders mounted upon the ends of the columns 19 position the sleeves 24 and hence the cylinders 23.
Water for the operation of the plungers 22 is admittedto the cylinders 23 through openings 27 in the outer ends thereoffrom water-supply pipes 27. Each of the plungers 22 is .retracted after it has done fastened at theirinner ends to the guide" blocks 18 and having .their outer ends connected to yokes 29 respectively actuated by pistons 30 entered at their inner ends into small auxiliary hydraulic cylinders 31 located above and below the main cylinder 23; Water pressure tending to move the-plungers 22 .outward-is constantlymaintained in removed from the main cylinders 23.
In using the machine, the billet 9 will be placed by suitable delivering means, not
which the two rams will be advanced simultaneously, whereby the billet will be introduced into the chamber 3 and then subjected to endwise compression by the simultaneous advance of the rams into the opposite ends of the said chamber, as will be described later. on. i
After a billet has been introduced into the blllt chamber 3, the mandrel 7 and die mandrel-holder 5 is 8 will be simultaneously advanced from Op-.
the line of the'mejchanisms already described for operatinggthe two rams 16, the effect of the whole machine being that of a large cross of. four as already stated. The mandrel-""a rfdfdies: operating mechanisms employ conical*l 10lders.5 and 6 conformed in shape to the conical centering-chambers 4 to insure the centering respectively of the mandrel 7 and the die 8 and to hold them firmly in-their operating positions against lateral thrust.
The .hollow die-holder 5 carrying the die 8 is screwed into a conical coupling-sleeve 32 mounted upon the inner end of'a long hollow stem 33 having an annular shoulder 34 about midway of its length and nonrotatably mounted in a cross-head 35- the ends of which are connected with the inner ends of piston-rods 36 the outer ends of which terminate in double-acting pistons 37 working in cylinders 38 mounted in a supporting casting 39. The said cross-head 35 is moved back and forth upon horizontal 44. By preference I employ a guide-tube 45' having its inner end'connected to the nut43 and arranged in line with the hollow stem 33, to receive and guide the product of the machine. The mechanism'provided for operating the mandrel 7 is the same as the mechanism already described, barring the provision for the escape of the extruded product of the'machine. Thus the conical solid rather than hollow and so on. \n
For locking the mandrel 7 and die 8 in their operating positions against outward thrust, I employ locking mechanisms which, as shown, are duplicates of each other. Each of these mechanisms consists of a sleeve 46 having interrupted threads and mounted for partial rotation upon the stem 33 at a point between the coupling-sleeve upon theinner faces. of bushings 47 located 130 columns 40 fastened at their inner ends by 32 at its forward end and 'the annularshoul- I e r in 14.
- hen the mandrel 7 and die For non-rotatably mounting in threaded chambers 48 in the main 'cast- 8 have been advanced into their home positions and their conical holders 5 and 6 have been firmly seated in the centering chambers 4 in the container 2, the' said holders, and there'- fore the die and mandrel, are firmly locked in such positions by'means of the said lock- 'ing-sleeves 46 which have advancedcorrespondingly with the hollow stems 33. The locking-sleeves 46 are now rotated a oneeighth turn as required for" interlocking their interrupted threads with those of the bushings 47. For turning the lockingsleeves 46, I employ operating-rings 49 encircling their outer endstand located within housings 50 secured by bolts 51' to the mainc'asting 14. The said rings 49 are encircled 2 by roller-bearings '52 and provided with toothed segments 53 meshing into racks 54 mounted on double-ended piston-rods 55 the 'respective ends of which enter locking-cylinders 56' and unlocking cylinders 57 to whichwater under pressureis admitted as required tomove the racksy54 so. as to turn the operating-ring 49 in one direction or the other as required for locking or unlocking the said locking-sleeves 49.
the operat-v ing-rings 49--upon the 'outer -ends of the locking-sleeves 46, the said rings are formed with wide locking-ribs 58 which enter clear- -ance spaces 59 between the interrupted threads of the saidsleeves, whereby the same are free to be moved back and forth with respect to the rings, but when once entered thereinto are non-rotatably coupled therewith. 1
Having now described my improved machine, I will now set forththe methodyof its operation. a A relatively long billet 9, preferably-cylindrical, though the cross-section form of the billet is immaterialfis' placed by .any suitable delivery mechanism, before one or the otherof the two rams 16 after which the said rams are simultaneously moved inward toward each other, whereby the billet is.

The retirement .of the mandrel and die for the introduction of a solid billet imandrel and die of the mandrel alone in the billet prior to subjecting the same to pressure, are the. salient features of my ,present invention. I It will be understood, of-qourse, that the diflt'erent parts of the machine herein shown and described willbe timed to .act in the lthe machine will'be'regulated-by the action in suitable concert of valves, not shown, but
