Applicationfiled october 6, 1923. Serial No. 667,061,. To all whom it may concern: Be it known that I, JOSEPH Moss, a citizen of the UnitedStates, residing at VVoonsocket, in the county of Providence, Stateof -Rhode Island, have invented a certain new and useful Improvement in Condenser Cylinders for Fiber-Preparing Machines, of which the following is aspe'cification', reference being had therein to the accompany -ing drawings. The invention has relation in general to the condenser cylinders or cages which are used in fiber preparing machines,'and'more' particularly to the means of seouringthe sheet metal shells of such cylinders or cages in place upon the heads or spiders thereof. The invention is applicable also in the casev of other cylinders of the same general'structure. Condenser cylinders. or cages, to the construction of which the invention primarily is designed .to beapplied, commonly are employed as elements of openers, 'pickers," and other machines employed foroperating upon cotton and other fibrous material. iInoperation, the air within a condenser :cylinder or cage 1s withdrawn through one or both ends of the cylinder or cage, or the side opposite the receiving sideuthereof, so as to produce a suction through theperforations of the cylinder shell,.and fibrous material 1' carried toward the cylinder by an oncoming current of air from the beater of-anopener or picker collects on the exterior of the said. " shell, and is discharged therefrom in the form of a sheet or bat'as the cylinder revolves. Heretofore the perforated sheet material constituting the shell of a condenser cylinder or cage. customarily has been secured in place in connection with the supporting heads or spiders through the application of solder. The results incidental to the use ofsheet metal and resulting departure from. the true cylindrical form that is desired. Also, afterinstallation of the cylinder or cage, in the event of fire starting in the opener or picker in connection with which the condenser cylinder or cage is employed, and being carried by the flaming flying particles of cotton to the cylinder or cage, as almost invariably is the case, the heat melts the solder by which; the sheet metal covering or "shell is held in place, so that the joints'of the latter open or separate. This necessitates removal of: the cylinder or cage, repair or substitution entailing considerable expense, and an enforced suspension of the use of the opener or picker. The object of the present invention is to provide an improved construction, of condenser cylinder or cage, or the like, which will do away'withj the use of solder and enable the shellto be applied and fastened in. place so that it will be perfectly secure, without loss of the true cylindrical shape which is desired, andv without liability to injury such as aforesaid in case of fire in the opener or picker with which the cylinder or cage is employed. Also, to provide a construction enabling the shell, in whole or in part, to be speedily and inexpensively replacedwhen" necessary, solas to restore the cylinder to perfectlcondition." The invention consists in a condenser cylinder or Qcage,' or thejlike, havinga plurality. ofheads or spiders, with each of the said heads or spiders formed with one or more slots or recesses in its, periphery, a cylindrical'shell comprising one or more circumferential sections of sheet material fitted to the peripheries of the said heads or spiders and having meeting edges formed with inturned flanges, and clamping members extending lengthwise of the cylinder, fastened together with the said inturnedflanges between them, and occupying the said peripheral slots or recesses of the heads or spiders. The invention includes also means for preventing displacement of, the shell lengthwise of the cylinder. An illustrative embodiment of the invention is shown in the accompanying drawings, in which,- Fig. 1 is an end View of a condenser cyl inder or cage containing the features of the invention, showing the means for and manner of clamping together the meeting edges of the sheet material, and securing them within the peripheral slots in the support I ing heads or spiders. Fig. 2 is a side View, partly in section on line 2, 2, of Fig. 1, certain parts being broken away. Fig. 3 is a view of the various parts which are immediately concerned with the invention, in disassembled relations. Fig. 4 is a view on a larger scale than the preceding views, in section on line 4., 4, of Fig. 5, looking in the direction indicated by the arrows. Fig. 5 is a view on the same larger scale, in section on line 5, 5, of Fig. 4, looking in the direction indicated by the arrows. Having reference to the drawings, The head or spider 1 at each end of the cylinder, and intermediate spider 15 when. the latter is employed, are each formed as heretofore with a flanged circular periphery 2 to receive the perforated material 3' constituting the shell of the cylinder, and with a hub 4 by means of which the cylinder is mounted upon a shaft5 for revolution, the respective heads or spiders being fixed to said shaft by means of keys 6. The'heads or spiders differ however from those of prior constructions in that each thereof is provided'with one or more slots or recesses 7, 7, in its periphery. The said perforated material 3 is formed at the meeting edges thereof with flanges 8, 8. As will be apparent, the perforated material may be in one continuoussheet extending completely around the heads 1 and constituting a onepiece shell, or may be made as illustrated herein of a plurality of sheets constituting sections of the shell. The two flanges 8 at the meeting ends of the sheet of perforated material, if one continuous piece is used, or at the meeting edges of two adjacent sheets, as in the construction shown here, are brought together within slots or recesses 7, 7 of the heads or spiders, and clamped between clamping members 9, 9, comprising two longitudinal strips, also occupying the slots 7 7, and extending the full length of the cylinder. The clamping members 9, 9, and likewise the meeting edges, are drawn together by means of a closely spaced series of bolts 10, 10, occupying holes 11, 11, in" the strips or clamping members 9, 9, and also through correspondingly spaced holes 12, 12, in the flanges 8, 8, and furnished with nuts 100, 100. To prevent the shell from moving longitudinally on the heads or spiders, a block of metal 13 is secured beneath the head of the bolt 10 at each end of the longitudinal joint formed by the said flanges and clamping members. This block 13 bears against the inward face 14: of the material of the adjacent end head a true cylindrical curvature, as in Fi 3, prior to installation on the heads. en fitted in 'place upon the heads, it is not subject to any distorting influences and is drawn down securely into a close fit upon the peripheries of the heads or spiders by simply tightening the bolts 10, 10, to draw together the adjoining flanges 8, 8, at each longitudinal joint. In the event of damage to one or all of the sheets of perforated material by fire or other agency, it is evident that such sheet or sheets may be speedily and inexpensively replaced to make the condenser cylinder as good as new. What is claimed as the invention is 1. A condenser cylinder for fiber preparing machines having a plurality of heads or spiders, with each of the said heads or spiders formed with one or more slots or recesses in its periphery, a cylindrical shell of sheet'material fitted to the peripheries of the said heads or spiders and having its meeting edges formed with inturned flanges, and clamping members extending lengthwise of the cylinder, fastened together with the said inturned flanges between them, and occupying the said peripheral slots or recesses of the heads or spiders. 2. A condenser cylinder for fiber preparingmachines having a plurality of heads or spiders, with each of the said heads or meeting edges formed with inturned flanges, clamping members extending lengthwise of the cylinder, fastened together with the said inturned flanges between them, and occupying the said peripheral slots or recesses of the heads or spiders, and means connected with said clamping members engaging with a head or spider to prevent endwise movement of the sheet material. 3. A condenser cylinder for fiber preparing machines having a plurality of heads or spiders, with each thereof formed with one or more peripheral slots or recesses, a cylindrical shell of sheet material fitted to the peripheries of the said heads or spiders and having its meeting edges formed with inturned flanges, longitudinal clamping members between which said flanges are interposed, bolts disconnectibly fastening such members together with the flanges between them, the said members and interposed flanges occupying the said peripheral slots or recesses, and blocks bolted to said members and holding the shell from endwise movement relative to the heads or spiders. i i JOSEPH MOSS.
