MACHINE FOR MAKING PlPES OR TUBES.
PECIFICATION forming part of Letters Patent No. 504,687, dated September 5, 1893. Application filed September 1, 1892- Seriel No. 444,823. (No model.)
To all whom it may concern: to enter the die-chamber 10. Immediately Be it known that I, GEORGE H. WINSOR, of below this die-chamber the base is vertically Central Falls, in the county of Providence perforated and the surface of this perforaa f State Of R ode Island, have invented certion is screw-threaded or provided with other tern new and useful Improvements in Mameans by which an interchangeable die 111s 55 chines for Making Pipes or Tubes; andl herefirmly secured therein, the opening through by declare that the following is a full, clear, the die determining the exterior diametrical and exact description of the same, reference shape and size of the pipe. The upp P being had to the accompanying drawings, tion of the die-chamber is also perforated 10 forming part of this specification. and in this perforation is removably secured 60 This invention has reference to improvethe upper portion of the core 12, the lower ments in machines for making tubes or pipes, portion of which extends through the die 11, the device being particularly adapted for the its cross-sectional shape and size determinconstruction of the tubes or pipes from metal ing the shape and size of the interior of the I 5 or material which will flow at a comparatively pipe. This core may be removed and a wire 65 low temperature. 01' cable to be covered maybe passed through The object of this invention is to produce the die.

Fig. 2 is a view of a portion of are journaled on the shafts 31 and 32 extendthe gate-rod provided with roller-bearings,- ing through the bodies of the pistons. The 85 and the cam by which these bearings are enupper ends of the piston-rods are furnished gaged to lift or depress the gate-rod. with metallic straps which are clamped Similar numbers of reference designate coraround the alternate eccentrics 33 and 34 responding parts throughout. mounted on the horizontal-shaft 35; this shaft In the drawings 5 and 6 indicate portions being journaled in the frames 36 and 37 and 0 of furnaces into which the metal, or other rnaprovided with a gear 38 which is driven from terial, is placed to be heated or prepared for any suitable compound driving-mechanism. its conversion into pipes. Connected with the furnaces 5 and 6 are Located between the furnaces 5 and 6 is a the supply-mains 39 and 40, situated in posistrong and substantial base 7 which is suptions to allow the liquefied material to read- 5 ported by a suitable foundation through ily pass through the same, and governed by which an opening is left for the pipe to pass the gates 41 and 42 moving in vertical-guides from the machine; the base isprovided with and having stems 48 and 44. The supplythe branch-channels 8 and 9 curving downmains are connected by the pipes 45 and 46 5 Ward toward the central portion of the base with the side extensions 47 and 48 of the cylroo inders, these extensions having channels formed therein to connect thepipes 44 and 45 with the inlets l5 and 16.
Pivoted between lugs on the extensions 47 and 48 are the bell-crank levers 49 and 50. In the depending arms of these levers are formed slots 5151 in which roller-bearings, on the outer ends of the rods for operating the gates 21 and 22, engage, and in the extension-arms of the levers are formed slots 5252 in which the roller-bearings of the stems 43 and 44 engage, these latter arms having also the slots 5353 in which roller-bearings on the lower ends of the gate- rods 54 and 55 engage. The gate-rods are vertically movable in guides with which the frames 36 and 37 are provided and are balanced by springs or counterweights. Extending in opposite directions from these rods are arms 56 and 57 having roller- bearings 58 and 59 which are alternately engaged by the cams 60 and 61, secured to the ends of the shaft 35, to lift and depress the gate-rods and to operate the bellcrank levers 49 and 50.
In the drawings the piston 26 is shown at the completion of the downward stroke and the piston 25 at the farthest point of upward movement. The cylinder 13 having been filled with material through the supply-main 39, the gate 41 of which remains open during the greater portion of the up-stroke, but closes rapidly during the last quarter of that stroke by the engagement of the cam 60 with the roller-bearing 58 on the arm of the gaterod 54. In the meantime the gate 2! has also opened and as the piston 25 moves downward the material is forced through the outlet 17 and the channel 8 into the die-chamber and thence out through the space left between the inner surface of the die 11 and the core 12, the material reaching the die in such a condition as will retain the form into which it is pressed. In the meantime the piston 26 has been lifted and anew charge delivered from the furnace 6 to the cylinder 14, the out let-gate 22 of which has been closed to prevent the backward movement of the material which is alternately supplied to the cylinders and forced from them by the pistons into the die-chamber and through the die; the length of the pipe depending wholly on the amount of material supplied by the furnaces.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination of the reservoirs 5 and 6, the base 7 located between the same, the chamber 10, formed in the lower central part of the base, the chambers 8 and 9 connecting this central chamber with the upper part of the base a removable die secured through the lower wall of the chamber 10 and a removable mandrel secured through the upper wall thereof, guides 19 and formed in the upper part of the base 7, the gates 21 and 22 movable in said guides, the cylinders 13 and 14 secured to the base and having the inlets 15 and 16 and the outlets 17 and 18 connecting with the channels 8 and 9, the pistons and 26 movable in said cylinders and connected by the rods 29 and 30 with the eccentrics 33 and 34 carried on the shafts, and means for rotating said shaft, of the supplymains 39 and 40 connected with the inlets 15 and 16, the gates 41 and 42 for closing the mains, the bell-crank levers 49 and 50 having the slots 5151 in which roller-bearings of the stems of the gates 21 and 22 engage, the slots 5252 in which roller-hearings of the gates 41 and 42 engage, and the slots 5353 in which roller-bearings on the rods 54 and 55 engage, the vertically- movable rods 54 and 55, the arms 56 and 57 secured to said rods and carrying roller-bearings, and the cams 60 and 61, carried by the shaft 35, adapted to alternately engage the rollerbearings on the arms 56 and 57 to lift or depress the rods 54 and 55, as and for the purpose described.
In witness whereof I have hereunto set my hand.
GEORGE H. XVINSOR. Vitnesses:
