ROTARY DRIER.
Specification of Letters Patent.
Patented April 2, 1907.
Application filed November 30, 1906. Serial No. 345,769.
To aZZ whom it may concern:
Be it known that I, HERMANN BRINKER, a citizen of the United States, residing at Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in Rotary Driers, of which the following is a specification.
In rotary dryin -cylinders employed in paper-mills, for instance, where the fabric is dried by running over the peripheral surfaces of rotating metallic hollow cylinders heated by steam, there is considerable inequality in the temperature of the dryin -shell at the different points in its length, portions near the ends of the shell being hotter and colder than the other portions. The consequence is either that the fabric is subjected to unequal drying heat at various points in its Width or else that a portion of the length of the dryin -cylinder must be sacrificed by being used only on comparatively narrow fabric.
My invention is designed to overcome this diflic'ulty.
My improvement will be readily understood from the following description, taken in connection with the accompanying drawings, in which Figure 1 is a vertical longitudinal section of a rotary drier embodying my invention, and Fig. 2 is a similar section at one corner of an ordinary and defective drier. I
Giving consideration to Fig. 2 of the drawings, 1 indicates the usual shell of the drier; 2, the usual head; 3, the usual portion of the shell projecting as a flange beyond the head, and 4 the juncture between the head and shell. The portion 3 of the shell is not in.- teriorly exposed to the action of the heatingsteam and is therefore always materially colder than the portion of the shell inwardly beyond the head. Again, the metal at 4, where the head joins the shell, is necessarily of considerable bulk, liberal fillets being requisite in order to avoid dangerous weak ening shrinkages in casting. The peripheral portion of the shell outwardly opposite the portion 4 is at some parts likely to be much hotter than other portions of the shell. Where the character of fabric being dried is such that a uniform subjection to drying heat along the width of the fabric is important, it is customary to so limit the width of the fabric relative to the length of the shell that the edges of the fabric will always be a considerable distance inwardly from the points where the heads join the shell. The
result is, first, that long driers can deal only with comparatively narrow fabrics, and, second, that the edges of the fabric are at some distance inwardly from the side frames which support the driers, thus very seriously incommoding the attendants in breaking and starting the fabric.
Now giving attention to Fig. 1, which illustrates my improved drier, 5 indicates the shell of the drier; 6, the journals; 7, one of the heads, illustrated as being of the seam less typethat is to say, cast integral with the shell, as is usual; 8, the other head, which in this instance is illustrated as being separably bolted to the shell, as is also usual 9, the bolts securing the separable head to the shell, and 10 longitudinally-outward and radially-inward curved extensions of the metal of the shell at its ends to join the heads. The extensions 10 where they join the shell may be of the same thickness as the shell, and it is to be observed that the entire periphery of the drier becomes equally exposed to the heating action of the interior steam. The result is that the entire peripheral face of the drier is available for satis factory drying action on the fabric. This permits the drying of wider fabrics on a given length of drier or the use of shorter driers for drying given widths of fabric. Again, as it becomes practicable to have either or both edges of the fabric running close to the end of the drier the distance between such edge or edges and the supporting-frame of the driers becomes very much less than is practicable under ordinary constructions of driers, the result being an increased convenience for the attendants along with the possibility in original construction of generally narrowing the drying part of a paper-making machine designed to deal with a given width of fabric.
I claim- A driercomprising a cylindrical metallic shell having at each end an extension of substantially the same thickness as the shell and curving longitudinally outward and radially inward and having journal-heads joined to such extensions, substantially as set forth.
HERMANN BRINKER.
