MACHINE FOR RQLLING SEAMLESS HOLLOW BODIES.
SPECIFICATION forming part of Letters Patent No. 430,977, dated June 24, 1890. I
Application filed November 25, 1889. Serial Ila-331,534. (N0 model.)
To all whom it may concern:
Be it known that I, CARL TELLERING, a subject of the Emperor of Germany, and a resident of Benrath, near Dusseldorf, Germany, have invented certain new and useful Improvements in Machines for Rolling Seamless Hollow Bodies; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to improvements in machines for rolling seamless cylindrical bodies from metallic rings.
In carrying my invention into effect the ring to be operated upon is preferably composed of a number of long cylindrical rings of small diameter swaged together, so as to form a seamless homogeneous ring or disk having a central opening corresponding in size with the interior of the article to be produced, and the wall thereof being considerably thicker than the wall of the finished article. It is obvious, however, that the said ring may be constructed in any other manner found convenient, it only being necessary that it shall be of such a nature that when subjected to the action of rollers, in the manner hereinafter described, it will assume the desired form.
Many attempts have been made to provide machines for rolling seamless hollow bodies from homogeneous metallic rings by subjecting such rings to the action of rollers, whereby their walls were reduced to the desired thickness for the finished article. Some of these machines have been more or less successful in practice, but generally they have been of such a costly and complicated character as to preclude their introduction into extensive public use.
The object of my invention is to provide a machine simple and durable in construction, and in which articles of the character and nature above set forth may be produced in an inexpensive and economical manner.
The invention consists in the combination, with a frame or bed, a mandrel for carrying the ring to be operated upon, and supports, one of which is horizontally movable for carryin g said mandrel, of a pressure-roller driven from a suitable motor, and means for varying the distance between the mandrel and roller and increasing or decreasing the pressure on the interposed ring, as hereinafter more fully set forth.
It also consists in the combination, with a frame or bed, of a mandrel for receiving the ring to be operated upon, a rigid support, and a horizontally-movable support carrying said mandrel, the movable support being provided with a series of rack-l eeth, and a pinion meshing with said teeth, having a shaft and crank or handle, and a pressure-roller for operating upon the ring, and means for varying the distance between said mandrel and roller and increasing or decreasing the pressure on the interposed ring, substantially as described.
The invention also consists in certain other novel features of construction and new combinations of parts, which will be hereinafter more fully described, and then pointed out in the claims.
In the accompanying drawings, Figure l is a vertical central sectional view of an ap paratus constructed according to my invention. Fig. 2 is a front elevation of the same. Fig. 3 is a side elevation of a modified construction of apparatus. Fig. iis afront View of the same, partly in section, in a plane perpendicular to that of Fig. 3. Fig. 5 is a plan view, and Fig. 6 is a horizontal section on the line :0 a; of Fig. at.
In the said drawings, referring now to Figs. 1 and 2, the reference-letters A A designate two uprights secured to abase or foundation A These uprights constitute the frame of the machine, and are connected together at their tops by a cross-piece B, provided with a downwardly-projecting arm B 'lheseuprights carry the pressing-roller w, the shaft of which is journaled therein and in arm B and provided with a pulley 10 which is connected with and driven by any suitable motor.
0 designates a vertically-reciprocatin g support, in which is journaled one end of the mandrel to, which carries the ring to be operated upon. On each side this support is provided with vertical grooves, in which work the flanges B of said uprights A A. This support is provided with an extension C and a horizontal aperture 0 in which works the extension D of the horizontally-movable support D. This support D carries the free end of the mandrel, and is made movable, so that said end can be freed for the purpose of putting on andtaking off the rings. The under side of extension D is provided with a number of rack-teeth, which engage with apinion y, mounted upon a shaft y, journaled in extension 0, by means of which said supportD may be reciprocated.
C designates a downwardly-extending pr0- jection, forming part of extension C.
X designates a shaft journaled in the uprights A A, and having a pinion X and cam X Gearing with pinion X is a rack-bar Y, which forms or is connected with the pistonrod of a force-pump Z. It will be seen that ure for rolling is obtained by the employment of the eccentric disk X the shaft of which restsin two bearings on the supports E and F, and which can be regulated by piston Y of a force-pump, having ratchet-teeth engaging with a pinion X on the shaft of the eccentric X The mandrel w is constructed and operates similar to that shown in Figs. 1 and 2,except that its supports are not movable horizontally.
From the above description it will be seen that during the operation of rolling-the pressure on the ring may be gradually increased, whereby the said ring is brought to the desired thinness and a hollow article produced having seamless wall.
Having thus described my invention, what I claim is 1. In a machine for rolling seamless metallic hollow bodies, the combination, with the frame thereof, of a mandrel for-carrying the ring to. be operated upon, supports for said mandrel, one of which is horizontally movable, a pressure-roller driven from a suitable motor, and means for varying the distance between said roller and mandrel and varying the pressure on the interposed ring, substantially as described.
2. The combination, with the frame, of a mandrel for receiving the ring to be operated upon, a rigid support, and a horizontallymovable support carrying said mandrel, the movable support being provided with a series of rack-teeth, a pinion meshing with said teeth, having a shaft and handle and a press ure-roller, and means for varying the pressure between it and the mandrel, substantially as described.
3. The combination, with the frame A A and roller w, supported therein, of the supports 0 and D, having extensions 0 D, respectively, the pinion y, meshing with teeth on the extension D, and the mandrel'w, carried by said supports, substantially as described.
4. The combination, with the frame A A cross-piece B, having dependingarm B and the pressure-roller w, of the supports 0 D, having extensions 0 D, respectively, the pinion y, meshing with rack-teeth on the extension D, and the mandrel w, carried by said supports, substantially as described.
5. The combination, with the frame A A and pressure-roller 'w, of the supports 0 D, the shaft X, having pinion X, and eccentric X the piston or connecting-rod Y, having teeth meshing with said pinion, and the mandrel supported by supports 0 D, substantially as described.
6. The combination, with the frame A A, cross-piece B, depending arm B and pressure-roller w, of the supports 0 and D, having extensions 0 D, extension D being provided with rack-teeth, the pinion y, meshing with said teeth, the projection (J the shaft X, pinion X, eccentric X and rack-bar Y, substantially as described.
In testimony that I claim the foregoing as my own I have hereunto set my signature in the presence of two witnesses.
CARL T ELLERING.
Witnesses W. MICS, FRITZ POTTHART.
