1 Claim.
' 1,968,679, issued July 31, 1934 to Frank A. Ger- 13.011, and 1,969,570, issued August 7, 1934, to Albert Matthews. More specifically its objects are to provide such disposition of the joints between parts that their assembly is facilitated; and that after assembly all joints between the principal parts are between surfaces having extent from the axis of the cylinder, so that should any part of the contents of the cylinder in its operation catch in openings at the joints, such parts may dislodge themselves without damage.
The exact nature of this invention together with further objects and advantages thereof will be apparent from the following description taken in connection with the accompanying drawing, in which Fig. 1 is a view in front elevation of a washing cylinder embodying the invention, parts being broken away to show details of construction; Fig. 2 is an enlarged sectional elevation transverse of the cylinder as in the plane of line 22, Fig. 1, the line ll in Fig. 2 locating. the sectional parts appearing in Fig. 1; Fig. 3 is a view showing the outline of one of the transverse members employed in the cylinder; and
I Fig. 4 is a perspective view showing details of the manner of joinder of the parts.
With reference now to the drawing, the cylinder shown has three compartments longitudinally spaced between four generally circular members I disposed transversely of the cylinder axis. These members I are generally similar except that the end members are provided with flanges l' fitting about transmitter castings 2 to which they are riveted as indicated in Fig. 1 so that the cylinder may be supported between and driven by the two transmitters 2 as is usual in the art.
The members I are provided with circumferentially spaced peripherally opening recesses la, four being shown for each member I, the members being so disposed with relation to each other that their recesses la are aligned along the cylinder.
For each row of recesses thus formed there is provided a lifting rib 3, of U form as indicated Figs. 2 and 4, each seating in the recesses of its row and secured to the transverse members I by stirrups 4, each stirrup being welded to its adjacent transverse members I and lifting rib 3. The leg parts of the lifting ribs preferably extend radially outwardly from the axis of the cylinder, coextensive with the peripheries of the circular members I. Endwise, the lifting ribs extend beyond the end members I, coextensive with their flanges I, seating in suitable openings provided as usual in the transmitters 2.
Thus there is defined, between each adjacent pair of lifting ribs and between each adjacent pair of transverse members I, a panel opening having a pair of straight edges and a pair of arcuate edges. For each such panel opening a cylinder sheet panel 5 is provided, each having a pair of straight edges with outturned flanges 5a alongside and secured to the corresponding extremities of the corresponding lifting ribs 3, and each having a pair of arcuate edges with outturned flanges 5b alongside and secured to the peripherally extending extremities of the corresponding transverse members I. The cylinder sheet members 5 together thus define a substantially complete cylindrical wall, radially outstanding from which are a number of flange parts along the lifting ribs 3 and transverse members I. The openings at the lifting ribs may be closed by fill pieces 6 having outturned flanges 6a corresponding to the flanges 5a of the cylinder sheets 5. The parts thus outstanding from the general cylinder wall are welded together as best indicated in Fig. 4, making a complete welded cylinder reinforced by outside flanges running both longitudinally and circumferentially, each being formed of three thicknesses of sheet metal.
It will be apparent that the order of assembly of the parts will be as above, ample access being had for interconnecting the transverse members I and lifting ribs 3 by their stirrups 4, before mounting the cylinder sheets 5. Also it will be noted that the assembly does not require the usual complicated jigs and fixtures for holding the parts together during the assembly.
Where the cylinder is to be employed for washing purposes, the principal parts are perforated as indicated in Figs. 1 and 4, as will be appreciated by one familiar with the art.
For each of the three compartments of the cylinder, one of its cylinder sheets 5 is provided with an opening 1 for which a door 8 is provided. Each door 8 is mounted for peripheral sliding movement in guideways generally indicated at 9 between a closed position against a stop It! and an open position. The guideways of course are arranged to space the doors to clear the described flanges en the Cylinder, as indicated in Fig. 2, further details of the doors and their mounting being immaterial here.
What I claim is:
In a cylinder of the class described, a plurality of generally circular members disposed transversely of the cylinder axis in, spaced relation with each other and having circumferentially spaced'peripherally opening recesses, said members being disposed with their said recesses aligned, lifting rib members of channel .form disposed longitudinally of said axis, seating in said recesses with longitudinal edge parts extending to the peripheries of said circular members, whereby a plurality of panel openings are defined, each disposed between an adjacent pair of said lifting rib members and between an adjacent pair of said transverse members, and cylinder sheet members for said panel openings each having a pair of straight edges with outturned flange parts alongside and secured to the corresponding lifting rib member edge parts, and a pair of arcuate edges with outturned flange parts alongside and secured to the corresponding peripheral edge parts of said transverse members, whereby all said members are interconnected at their said edge parts and the latter are all disposed outwardly beyond the confines of said cylinder.
