REWORKING- TUBES.

Specification of Letters Patent.

Patented Nov. 17, 1908.

Application filed April 14, 1908. Serial No. 427,015.

To all'whom it may concern:

Be it known that I, WILLIAM H. RICH- ARDS, citizen of the United States, residing at Canonsburg, county of lVashington and State of Pennsylvania, have invented certain new and useful Improvements in Reworking Tubes, o f which the following is a specification, reference being had therein to the accompanymg drawing. This invention relates to an apparatus for reworking pipes, tubes and cylindrical bodies into plate material, whereby the superior quality of metal in scrap material of this character may be utilized.

he invention has for an object to prov ide means for heating the tubes, for splitting and flattening said tubes while heated, and subsequently rolling the flattened plate into the desired thickness for future use.

A'further object of the invention is to provide a plow having a cutter at its apex and curved rearwardly extending faces whereby the tube is slitted and pressed into substantially fiat form at a single operation, together with means for presenting the plate thus formed to a rolling mill at an angle to the longitudinal axis of the tube.

Other and further objects and advantages of the invention will be hereinafter fully set forth and the novel features thereof delined by the appended claims.

In the drawing :Figure 1 is a plan showing an application of the invention; Fig. 2 is a vertical section on line 2 2, Fig. l; Fig. 3 is an enlarged plan of the plow and tube bed; Fig. 4 is a side elevation of these parts; Fig. is a detail perspective of the tube as split and iiattened.

Like numerals refer to like parts in the several views of the drawing'. y

The numeral 10 designates a furnace which may be of any desired construction suitable for heating tubes, and is here shown as a down draft furnace having fire boxes 11 at opposite sides and chimney 12 so that the products of combustion pass downward through the chamber 13 Awhich is provided with an inclined floor 141- apertured at 15 and adapted to support the pipes 1G, as shown in Fig. 2. From this chamber a flue 17 extends' to the chimney 12. The tube chamber is provided with an inlet door 18 and a. discharge 19 at the opposite side thereof, the latter communicating with the platform 2() by which the heated tube is delivered upon the bed 21 extending parallel to the length of the tube and provided, if desired, with .a recess 22 to retain the tube in proper position. At one end of this bed a plow 23 is disposed and adapted to reciprocate for the length of the bed, it being propelled by any desired power, for instance, the piston rod 24 extending to the power cylinder 25. This plow is provided at its apex with a reinovably mounted cutter 2G which may be interchanged for different sizes of material and is preferably inclined downward from the top so as to assist by its shearing action in holding the tube upon the bed (hiring the splitting thereof. The plow is provided at each side with rearwardly extending cuived faces 27 merging into a horizontal plane parallel to the bed and at the point a flattening roller 2S is pivotally mounted in the opposite sides of the plow so as to traverse and flatten the heated tube while holding it in firm contact with the bed 21.

For the purpose of retaining the tube or pipe 1G against longitudinal movement, any

desired holding device may be used, for in-l stance, a gripper 29 extending upward from the bed at one end of the tube recess and adapted to enter the tube, as shown in Figs. 1 and 2. This gripper is carried by the rod 30 and normally held out of contact by the spring' 31 extending from the rod to the casing 32 thereof, while the gripper may be firmly held by a treadle connection, as shown at 33 or any preferred means. l

In the operation of the invention it is desirable that the plate formed from the tube should be rolled at an angle to the longitudinal axis of the tube, and for that purpose the bed is normally disposed at an angle to the iolls 34 comprising a portion of the rolling' mill and is adapted to rotate into a position parallel with these rolls, as shown by dotted lines in Fig. 1. Various means may be used to secure this movement,one form of which comprises the sector 35 carried by the bed and adapted to engage the. gear 3G which is driven from the geared shaft 37. For th(` purpose of changing the direction of tra-vel of the bed a sleeve 3S is splined upon' the driving shaft'394which is rotated from any suitable source of power applied at the pulley 40 or may comprise the shaft of' one of the mill rolls. This sleeve is provided with oppositely disposed bevel gears 41 and 42 either of which may be thrown into mesh by the shifting lever 43.

In the operation of the invention, the tube to a is first heated to the desired temperature and then secured, upon the bed, when the plow advances and simultaneously cuts and bends the softened material of the tube from the vcylindrical into a substantially flat form,

the desired thickness. It will be seen that this construction presents means by which or flattened by the scrap pipes tubes and cylindrical bodies containing the best quality of material may be practically utilized for lates and the s )lit, ting and flattening rea 1ly accomplishe by a smgle operation as the tube when heated can be readily split by the cutter and bent plow in its passage thereover, as shown in 41ig. 5.

Having described my invention and set forth its merits, what I claim and desire to secureby Letters Patent is l. In a machine for reworking tubes, a base for sup orting a tube, means for simultaneously slitting and bending outward vin opposite directions the slitted edges of the tube, and means in the rear of the slitting meansI having a face substantially parallel to the base and adapted to force the outwardly bent tube into .contact therewith.

2. In a machine for reworking tubes, means for supportin a tube, and a shtter provided with opposite y inclined portions extending toward the su porting means and outwardly and rearward y and vada ted for flattening the tube into contact w1th the supporting means during the slitting action. i
