I 'Application led Septemhexll, 1923. Serial No. 862,051.
A The invention relates to fluid cooled rolls, and is designed particularly Yforuse in apparatus for'continuously rolling a glass sheet. such' as illustrated andv described inlthe apa plication of Frederick Gelstharp, Serial No.
656,441,although the roll construction is 4 not limited to use in this particular relation.
In apparatus for rolling glass, which fluid cooled rolls are employed, itiis'desirable that lu the 4rolls should be cooleduiiiformly, -as otherwise the rolls will soon be warped out of shapeso that it is impossible to roducef asheet of .uniform thickness, and urther-,
more the application of a non-uniform cooll llng eiect on the glass sheet or ribbon being formed introduces strain into the sheet, in-
`creasing the breakage. One object of 'the present invention is the provision of improved means for securing a uniform cooling effect throughout the length of the roll. Further objects of the invention are (1) the provi sion of rolls which may be made without diculty, 2) which are of simple construction, and (3) in which asubstantial part of the construction is capableofjreusealfgter the outer portion of the roll isb-worn so that-it.
is not suitable for further service. One embodiment vof the invention is illustrated in the accompanying drawings wherein:
'Figure 1 is ajlongitudinal section through' the roll. Fig. 2-is a section through the'ends of the rollon a larger` scale than 1e Fig. 3 is a side elevation of lthe corew lits into the cylindrical casing. Figs. 4; and sa 5 are end elevations of the roll.4 Figs. 6 and 7 are sections on the lines V -V and VI-VI respectively of Fig. `1. .And Figs. 8, 9 and- 10 are detail views of the cage "constituting,
a part of thestuling box construction at'each end of the roll. "f g The roll consists of a cylindrical casing 1, a core 2 which is circular in cross section and fitssnugly into the casing, the swivels 3 and 4 at the ends of the rolls, anda stuffing box construction for use in connectionwith the swivels. The roll.,v is designed to be used in4 conjunction with another' similar roll for providing a pass therebetween, and the dotted line ligure marked 5 indictcs the cross 00 section of vthe sheet ofglass which is to be formed by the rolls. v f The core 2 is provided with the plurality of grooves 6 extending longitudinally thereof. At one end, these grooves terminate short of the end of the core as indicated at 7, while at :the other end they extend clear to the end of the core as indicated at' 8. The latter end of the core is provided with a part 9 of reduced diameter fr the purpose of proyiding asupport fora packing gland as here- 00 mattei-set forth. .The core 2 is held against rotation with respect to the casing 1 by means of a pin.10 which has'a driving fit in v'suitable perfor-ations extending through the core and .casing The roll is rotated b means Aof a wobbler 11 which is screw thread -ed into :the right hand end of the casin and is held against turning b means of a pin 12 which has a. driving lit 1n suitable pertoral ilons extending through the casing and wob- The swivel 4 has an inlet connection 13 andV an outlet connection 14 communicating Y with the annular passages 15 and 16 respec- .tively andthese annular passages are `adapted to communicate with perforatinos 17 and 18 vextending through the casing. As indicated in Fig. 7, the perforations 18 commulnicate with alternate ones ofthe grooves 2.
The other setof perforations 17 communi- 80 cate with. the other grooves 2. The swivel 3 at the other end ofrtheroll is similar in lconstruction tothe swivel 4 Vand has anI inlet 19. and a. outlet 20 communicatin A.with annular passages 21 and 22 whic in lturn 'communicate with perforatinos 23 and V24 extendin@r through the wall of the `casing 1.
The perijorations 23 communicate ywith the saine grooves 2 with which the perforations 18at the other end ofthe casing `communicate,- whle the perforations 24 communicate with the same grooves with which the perforat-ions 17 communicate at the other 'end of the casing'. lSuitable supply pipes are coupled to the inlets and outlets so that, when, in use, a` cooling luidsuch as water passes in`through the inlet 13 along. the grooves A6 and out atthe outlet 20, while a second flow ofl water passes` in through the inlet 19 along the alternate groovesf and loo 'out at the outlet 14. 'A flow of cooling liquid is thus provided in the alternate grooves in opposite directions, thus tending to give a. more uniform cooling than-if the liquid f all passed through in the same direction, in '105 which case the roll would be cooled to a greater extent at the inlet end.
Suitable packing for the `swivel 4 is provided by the packing rings 25, 26 and 27 pressed forward by means of the gland 28. ug
The gland itself is adjusted b means of the screws 29 extending through t e ring 30, and this ring is secured to the end ofthe casing by means of the set screws 31. `Inorder to apply pressure from the rings 27 to the rings 26, anv annular cage or follower 32 shown in plfyst an 34 connected by the bars 35.
detail in Figs. 8, 9, and 10 is preferably emsuch cage consisting of the rings 33 This cage or follower, by reason of its skeleton formation, permits a free flow of liquid through the annular passa e 16 and to the various perforations 18. he ring portion 34 is provided with a pair of screw threaded cavities 36 into which a tool may be screwed when it is desired to withdraw the .cage from its position of use inside the swivel.
y The arrangement for pack`ng the swivel at the left hand end of the casing is the same as that just described in connection with the swivel 4 so that no further description is necessary. In order to pack the ends'of'the grooves '6 at the left. hand end of the core, the gland 37 is employed, such gland being `forced into position b means of the bolt38 threaded into the pro]ectio n 9 on the end of the core. Suitable-packing rings 39 are employed intermediate the end of the gland and the ends of the grooves 6.
The parts may be readily assembled and dis-assembled and the coolin of the roll is secured by reason of the iw of cooling liquid ythrough the grooves in opposite directions so that any warping of the roll due to uneven cooling is avoided. When the casing 1 becomesworn to such an extent that it is unsuitable for further use, a duplicate casing is supplied with which the core and 4swivels may again be used, if the core is not too tightly held inthe casing, a tight fit being insured byshrinking the, casing onto the core. The gland'37 gives. accessl tothe ends of the grooves 6 for cleaning,'and if desired these grooves might be extended clear to the other end of the core and a gland provided there so as to-give still greater accessibility to the groovesfor cleaning purposes.
What I claim is':
combination 1n a roll, an outericylin- I drical casing, al core adapted to fit in such casing and having its surface provided with groovesmextegnding longitudinally thereof parallel with the axis of the roll, and a" swivel at each end of the casing, each of which has an'inlet connection commun1eat-- ing with alternate grooves and an outlet der of the grooves, whereby a circulation of coolingflud may be provided in both direcf tions, t rough the roll.
