IMPROVEMENT IN DRYING-CVLINDERS.
Specification forming part of Letters Patent No. 190,548., dated'May 8, 1877; application filed April 7, 1877.
To all whom it may concern Be it'known that 1, CHARLES C. BUTTER- WORTH, of Philadelphia, Pennsylvania, have invented a new and useful Improvement in Drying-Cylinders, of which the following is a specification The object of my invention is to make a substantial drying-cylinder having a uniformly smooth exterior, and this objectI attain in the manner which I will now proceed to describe, reference being had to the accompanying drawing, in which- Figure l is a section of a portion of the cylinder; Fig. 2, a transverse section of the same,
and Figs. 3, 4, and 5 portions of the cylinder drawn to an enlarged scale.
The body A of the cylinder consists, as usual, of tinned plates of sheet iron, the sheet a being bent to a circular form, and its edges united by a double lap-joint, b, whioh'projects into the inside of the cylinder, so that the uniformity of the exterior may not be interrupted excepting by a slight cavity at w, and this is filled with solder in finishing the body.
A flanged head, B, is snugly fitted into each end of the cylinder, to which'the flange is soldered, each head having a hollow journal, d.
In the interior of the body, at suitable intervals, are -re-enforcing rings 1), one only of which is shown in the drawing, the ring being of iron, and preferably of the sectional form shown in Fig. 5, so that there may be a comparatively broad flange, i, to be soldered to the body, and a deep flange, j, to add strength to the ring, and consequently to the said body.
The double-lapped joint contributes materially to the strength of the cylinder, and in order that it may do this efi'ectually it should extend from end to end of the body, and not be interfered with by the internal re-enforcing rings; hence the latter are recessed at the edge, as shown at y, in Figs. 3 and 4, for the reception of the projecting joint.
The edges of the heads are also recessed for the reception of the said joint.
I claim as my invention The within-described drying-cylinder, consisting of the body A of tinned sheet-iron,'
with internally-projecting double-lappedjoint, the internal re-enforcing rings D, recessed at the edges to receive the said joint, and the heads B, all being combined as set forth.
In testimony whereof I have signed my nameto this specification in the presence of two subscribing witnesses.
CHARLES C. BUTTERWORTH.
