seats Within a recess formed in one side of the lturbine-disk, and a second collar or nut is screwed on a threaded portion of the bolt and clamps rigidly against the inner Wall of e, second recess formed on the opposite side of the turbine-disk, so' that *the central portion of thebolt is rigidly clamped to the disk, While its opposite ends are arranged to Work freely in t e openings formed in the collars 17. The collar-openings are counterbored at their outer ends to form pockets for the reception of helical compression-springs 21, and the outer ends of the bolts are threaded for the reception of nuts 22, by which the stress .of the springs may be adjusted, these nuts being preferably provided with circular peripheries having notches for the reception of a ,spanner-vvrenchri, The nuts andl springs are protected by a" housing sleeve 23, one of which is fitted on each shaft-section 13 and 15, these sleeves having pockets for the reception of the nuts and being held to the collar 17 by suitable screws 24. i
Secured rigidly to the outer end of each of the shaft-sections 13 and 15 is a collar 25, having openings for the passage of a bolt 26, said bolt having a rigid collar 27, that is seated in a small recess formed in the cuter face l of the collar, While nuts 28, arranged in the threaded 'end of the bolt, serve to firmly clamp the latter to the collar. To each of the shaft-sections 12 and 16 is l secured a collar 17, having bolt-receiving gravity and vtaken up by the .ing sleeve continues the centrifugal force will be balanced and the disk will Vseelr its true center of will thereafter revolve steadily around 'an axis which may or may not be in theplane of the axis of the shaft-sections 12 and 16. Any vibration of the disk due to any defect in construction or tothe uneven vdistribution of the propellin force Will be bration being absorbed and the movement transmitted to the shaft-sections 12 and 16 being,r smooth, regular, and uniform, so that the machinery will be driven at regular speed and Without any vibration Whatever.
springs 21, al shocks and vi-A essere 'Having thus described the invention., what is claimed is- 1. vIn an elastic-fluid turbine, a turbinedisk, a disk-carrying shaft formed of a number of sections having interfitting end meinbers, the end sections being arranged in fixed bearings, and connecting means arranged between said sections and including springpressed bolts that tend to maintain the sections in alinement.
2. ln an elastic-Huid turbine, a turbinedisk, asectional shaft having interlitting end portions arranged to permit free play of the sections, the turbine-disk being secured to the central section, and the end sections being arranged to revolve in fixed bearings,in termediatesections, collars carried thereby and yieldably connected to the turbine-disk, and yieldably-connected collars carried by the intermediate and the end sections of the shaft.
3. In an elastic-fluid turbine, a cylinder, a shaft including end sections, a central section, and intermediate sections, the latter being disposed between the central section and the end sections, all of said sections having interfitting ball-and-socket connections, a turbinedisk secured to the' central section, bolts rigidly secured to the turbine-disk and having their opposite ends projecting from the sides of the dislr, collars clamped to the inner ends of the intermediate shaft-sections and provided .with openings for the passage yof said bolts, springs surrounding the end portions of said bolts, nuts arranged on .the threaded ends of the bolts and serving to adjust the stress of the springs, housing-sleeves connected to the collars and servingr to house and. protect the nuts and springs, collars rigidly secured to the outer ends of the intermediate sections, bolts proiecting from said co1- lars, sleeves secured to the end sections of the shaft and provided with openings for the passage of the bolts, springs surrounding the latter bolts, nuts arranged on' said bolts and serving to adjust the spring, housing-sleeves for protecting the nuts and springsf` and bearings for the support of the end sections of the shaft.
ln testimony that `We claim the foregoing as our own We have hereto afiixed our signatures in the presence of two Witnesses.
