RUDOL'F THIEL, OF LUBECK; GERMANY. HEATING DEVICE FOR SPlNNlNG-LATl-IES- To all whom it may concern:
Be it known that I, RUDOLF THIEL, a citizen of the Empire of Germany, residing at Liibeck, in the Empire of Germany, have invented a 'newand useful Heating Device for Spinning-Lathes, of which the following is a'specification.
My invention relates to improvements in heating devices for spinning-lathes whereby it is rendered possible to mai'ntain'the heating device at a from the blanli while the latter is being spunthat is to say, during the reduction or part of the blank-so that the metal 1s at all times heated up to the right tem erature I tion through the heat' and cannot become brittle and crac ed.
The objects of my improvement are, first,
' to rovide an annular plate on the bed of the lat e, which plate surrounds the blank; sec- .ond, to provide aplurality of hollow and perforated heaters, of which certain'are se cured on the annular plate, while the other heaters alternating therewith" are radially guided in the plate, and, third, toprovlde a device for simultaneously feeding the movable heaters on the annular late so as to maintain the roper distance etween them and the blank I attain these objects by the heating device illustrated in the accompanying drawings, in )VhlClh .Fi e -1 is an elevation ofh part of a spinningathe and a vertical longitudinal secblank on the broken line F-in'Fi-g. 3. Fig. 2 is a horizontal section through'the heating device and the blank on the line C D in Fig. 1. Fig. 3 is a vertical cross-section through the line A B in Fig.1, and Figs. 4; to 8 represent vertical sections of various spun work:
pieces.
7 Similar characters of reference refer to similar parts throughout the several views.
The heating device comprisesan annular plate P and several heaters H to H. plate P is longitudinally adjustable on the ed 1 of the spinning-lathe by means of a' plate 2 and a bolt 3. This plate P is bored and arranged to receive an annular slide 4, which is prevented from longitudinally shift: I ing by its flange, and a bymeans of screws. (Nots own). Theslide 4 is provided with a handle 6, by means of whic ,it can be turned through a certain anglef The plate P is provided with several (byte an radial slots '77. in which slides Specification of Letters Patent. Application filed April 27, i906. Serial No, 267,604.

88 are mounted to move", In thes four slides'8 8 are secured four bolts 9 9,'which are pivotall connected with four pins 10' 10 in the annu ar slide 4 bymeans of four pairs of links 11 11, so that by'moving the handle 6- up and down thefour slides 8 '8 can be moved inward] toward the axis and outwardly, respectively. On the right ends of thekbblts 9 9 are fastened suitable ro 'ections 12-12 of the movable heaters H, H. The stationary heaters H and H are fastened with their I, and H, H5, H
vided wit-h suitable connections 14 14; to
which h0se'15 15 can be attached for thesupply of gas from some source. It will be seen that the movable heaters alternate feet 13 13 on the plate P. All heaters H to H are proincrease of the diameter of the res ect1ve'- with the stationary heaters and partake in the motion of the slides 8 8. On the front side a suitable space is left between the two stationary heaters H and H- for the introduction of a spinning-tool 19 or anypattern-roll, such as 20. V
. Figs. 4 to 8 show a few exam les of spun work pieces, which may be pro need on the spinning-lathe with the aid of the heating device, the blanks havlng been first drawn in any known manner.
The heating device is operated as follows: Assuming the workiece 16 to be produced to have the shape shown'at Fi 4, then a cylindrical blank, which is close at the one of a centering device 18 0 any known construction. The plate P is placed on the bed 1, and'the handle'fi is pushed downward, so as to lace the links ]1 11 radially, when the mova le heaters H, H, H, and .H. will occupy their extreme externalpositions, and their perforated internalfaces will be in the same circle 'as those of the stationary heaters. secured in such a position that the heaters H to H surround theblank on the respective'plaeewhere it-is to be spun. A suitable pattern-roll '20is put on a bracket 21, and the latter is secured in a convenient support 722 on the respective compound-slide rest. This atterm'roll '20 is then introduced into the blimkand set against its inside on the end, is secured on the face late 17 by means device and the The plate P is shifted to the, left andv s bracketor holder 23,and the latter is secured a support 24. Gas either alone or mixed with compressed air" 1s turned on by means of the respective valves or cocks and conducted through several or all hose 15 to the respective heaters H to H". The gas or the mixture of gas and air escaping from the perforations of the heaters is then lighted, so that the iiames commence to heat the metal of the blank. The lathe is started, and the spinning-tool is applied to the blank, as usual, in the gap between the two front stationary heaters H and H. The metal of the blank is uniformly heated, care being taken to so feed the movable heaters H 11*, H", and H by means of the handle 6 as to maintain the correct distance between their internal faces and the respective parts of the blank. It may be convenient to first admit the gas or the mixture only to the stationary heaters H", H, H H and H and afterward when the distance between them and the blank increases also to the movable heaters 11 ,11 I1", and H If the distance between the stationary heaters and the blank becomes too great for the gasflames to properly heat the metal, the supply of gas or mixture to the stationary heaters may be stopped and only that to the movable heaters be maintained. The metal of the work-piece is thus kept at the proper 7 suitable bracket will have to be temperature, so that it cannot become brittle and cracked, 4
As is evident from Fig. 1, the movable heaters require to have a cross-section in correspondence with the section of the patternroll 20. Allthe heaters are detachable and may be replaced by other ones in accordance with the required shape of the work-piece. When it is desired to hollow out the blank to a shape shown in Fig. 7, of course the pattern-roll of a corresponding shape will have to be applied to the blank from. without in the gap between the two stationary heaters H and 1-1, while the spinning-tool 19 on a a plied from within. The annular plate P siiould have an opening of such a size that it can be at once removed after the completion of the work-piece. I
The heating device may be varied in many respects without departing from the spirit of my invention.
Vllhat I claim as my invention, and desire to secure by Letters Patent, is
1. A heating device for spinning-lathes, comprising a plurality of members through which heat may be suppliedto the work, and means for advancing said members inwardly as the dimensions of said work is reduced.
