ROLL FOR DRIERS AND THE LIKE Filed May 25, 1941 lnvenror. Edwin H. Hansen by d Patented Nov. 18, 1941 ROLL FOR D'RIERS AND THE LIKE Edwin H. Hansen, Braintree, Mass., assignor to Andrews and Goodrich, Inc., Dorchester, Mass, a corporation of Massachusetts Application May 23, 1941, Serial No. 394,834
2 Claims.
This invention relates to metal rolls such as are used in drying apparatus for supporting cloth or other web material while it is being subjected to the drying operation.
Such rolls are frequently provided with an 8X- terior cloth-supporting surface of non-corrosive material, and one way in which rolls of this type have heretofore been made has been to take a steel tube of the size and length required for the roll and then to cover said tube with a sheet metal envelope of a suitable non-corrosive material, such as brass, copper, stainless steel, etc., the edges of the envelope usually meeting in a butt joint and being welded together, and the envelope also being welded to the steel tube at the ends. A roll made in this way is necessarily rather heavy because it involves the weight of both the steel tube and the weight of the envelope.
One of the objects of my present invention is to provide a novel roll which may have a clothsupporting surface of any suitable metal, which has a weight considerably less than that of a roll of the same size made as above described and which can be made at relatively low cost.
A further object of the invention is to provide a roll of this type which is well adapted for manufacture by the assembly method.
Further objects of the invention are to improve rolls of this type in the particulars hereinafter set forth.
In the drawing:
Fig. 1 is a longitudinal sectional View through a roll embodying my invention.
Fig. 2 is an enlarged sectional View on the line 2-2, Fig. 1.
Fig. 3 is a view of one of the expansion disks.
Fig. 4 is a perspective view of the split ring used in connection with each expansion disk.
Fig. 5 is a view of one of the end disks.
My improved roll comprises a tubular body member 3 having the length and diametrical dimension required for the completed roll. This body member may be made either as a seamless tube or as one which has a seam extending longitudinally thereof, and it may be made of any suitable material. If the roll is to have a noncorrosive cloth-supporting surface, then the tubular body member may be made of brass, stainless steel, or any other desirable non-corrosive material.
Each end of the tubular body member 3 is closed by a head 4 in the form of a disk which fits within the tubular body member 3 and is eventually permanently secured thereto in some suitable way, as by means of welding. Each disk head 4 has a central opening 5 for a purpose presently to be described.
Situated within the tubular member 3 are two split expansion disks 6, each having a central interiorly screw-threaded opening 1. Each disk is shown as split diametrically, as indicated at 8, and preferably the split or slit 8 will extend nearly but not quite across the disk. As shown in Fig. 3, this slit 8 extends from the peripheral point 9 on the disk through the center thereof to the point Ill. These expansion disks 6 are of a size to fit within the tubular body member 3, and each may have a diameter equal to the interior diameter of the tubular member 3, or, if desired, I may interpose a split band ll between the periphery of each disk 6 and the interior of the tubular member 3, as shown in the drawing.
12 indicate trunnion members which are cylindrical in shape, each member having its body portion of a size to fit the aperture 5 in the disk head 4. The inner end l3 of each trunnion member I2 is tapered and exteriorly screw-threaded and is adapted to have screw-threaded engagement with the screw-threaded opening I of one of the expansion disks 6.
In assembling the parts, the split bands II and the expansion disks 6 are inserted into the tubular member 3 and located in the proper positions, and the end disks 4 are then inserted into the ends of the body member 3 and are welded thereto, as shown at It. The expansion disks 6 and the split sleeves H are of a proper diameter so that said disks 6 and sleeves II will be held by friction in the position in which they are placed during the time that the end disks 4 are being welded to the body member 3.
The trunnion members l2 are then inserted through the central openings 5 in the end disks 4, and the tapered screw-threaded end l3 of each trunnion is inserted into the interiorly screwthreaded aperture 1 of the corresponding expansion disk 6. Each trunnion member is then turned to screw its tapered end further into the aperture 1 during which operation the tapered shape of the end I3 causes the disk 6 to expand and thus be firmly clamped against the interior wall of the body member 3. After both disks 6 have been firmly clamped in position, then the trunnion members l2 are locked to the end disks 4 in some suitable way, as, for instance, by welding them to the disks as indicated at I5.
The outer ends I6 of the trunnion members l2 may be reduced in diameter to form suitable trunnions on which the roll may rotate during the time that it is supporting the cloth or the Web material.
Inasmuch as the apertures 5 and 1 are formed centrally in the end disks 4 and the expansion disks 6, the trunnion members I2 will be in accurate alinement with each other and axially situated with reference to the tubular body member 3. Since the trunnion members are locked to the end disks 4 and the latter are permanently secured to the body member 3, there is no possibility that the clamping action of the expansion disks 6 against the interior of the body member 3 will become relaxed in any way, because the trunnion members I2 are turvented from turning movement relative to the body 3.
The result of this construction is a rigid roll which is relatively light in weight, and if the tubular member is of non-corrosive material, the roll will have a non-corrosive cloth-supporting surface.
The construction also has the advantage that the roll can be easily made merely by assembling the disks 6 and 4 with the body portion 3 and then inserting the trunnion members through the disks 4 and screwing them into the disks 6 to expand the latter into clamping engagement with the interior of the body 3.
The presence of the split bands H prevent the edges of the expansion disks 6 from deforming the Walls of the tubular body 3 when the disks are expanded.
I claim:
1. A roll for drying apparatus comprising a tubular body member, a disk fitting within the body member at each end thereof and secured thereto, each disk having a central opening, two expansible disks within the body member, each expansible disk having a screw-threaded central aperture, and a trunnion member extending through the central aperture of each end disk and having its inner end tapered and exteriorly screw-threaded for screwing into the screwthreaded central aperture of the corresponding expansible disk, and expanding said disk into firm clamping engagement with the tubular body member.
2. A roll for drying apparatus comprising a tubular body member, an end disk fitting within the body member at each end thereof and welded thereto, each end disk having a central opening, two split disks within the body member each having a screw-threaded central aperture, and a trunnion member extending through the central aperture of each end disk, the inner end of each trunnion member being tapered and exteriorly screw-threaded and having screw-threaded engagement with the aperture of the corresponding split disk, said disks being expanded by the tapered ends of the trunnion members and thereby held in firm clamping engagement with the interior of the tubular body member, each trunnion member being Welded to corresponding end disk.
