ing through the plug ill into the chamber 250', and each of these ports is of greater diameter than the small end of the nozzle hole leading from said chamber. This arrangement breaks the strength of the current and avoids clogging of the nozzle hole. In other words, if the nozzle hole were presented directly to the force of the current in the chamber (5, the current or suction in the nozzle hole would be so great that a leaf or other rubbish would (-ovcr and be held against the opening at the nozzle'and prevent further flow. This situation is relieved by providing the ports 32 of greater capacity opening into the chamber 30 to break the force of the current, and it a leaf or other rubbish covers one of the ports- 32, the current will pass through the others. Any rubbish that should pass through the ports will be caught by the screen 33 and can be easily removed by taking out the screwplug 31..

Having thus descr had our invention, we claim:

1. 1n a lubricating device for a turbine such as described, a feed head having a chamber formed therein with ports to the runner of the turbine, a bearing for the rotating shaft of the turbine also formed in said head and a nozzle screw threaded into a recess in said head forming an inlet of gradually increasing-diameter to admit the actuating medium to said hearing from said chamber, substantially as described 2. In a lubricating device for a turbine such as described, a casing having feed and exhaust heads with bearings tor the driving shaft, said shaft having a lungitudinal conduit therein, with radial openings to the bearing in the exhaust head and channels in the face of the rear end thereof to the bearing in the feed head and an inlet thereto to admit the actuating medium from said chamber, substantially as described.

3. In a lubricating device for a turbine such as described, a feed head having chamber forn'ied therein with ports to the runner of the turbine, a removable bushing seated in a recess of the head forming a bearing for the turbine shaft and a removable screw threaded nozzle adapted to admit the z lctuating medium to said bearing and to force the bushing from its seat, substantially as described. 4-. In a lubricating device for a turbine such as described, a feed head forming a feed chamber with ports to admit the actuating medium to the runner of the turbine, a bearing for the shaft of the turbine formed in said head and a screening chamber also formed in said head and having. openings to admit the actuating medium to said bearing from the feed chamber, substantially as described.

5. In a lubricating device for a turbine such as described, a feed head with a feed chamber having ports to the runner ot' the turbine, said head also having a bearing for the turbine shaft and a portion extending into said teed chamber forming a screening chamber having an opening to the bearing and a plurality of ports opening from the feed chamber to the screening chamber, each of said ports being of greater capacity than the opening from the screening chamber to the bearing, substantially as described.

6. In a lubricating device for a turbine such as described, a feed head with a feed chamber formed therein with ports to admit the actuating medium to the runner of the turbine, said head also having a bearing tor the turbine shat't formed therein and a ellow portion extending into said feed ch her with a removable plug forming. a screen ing chamber having a removable nozzle opening from the screening chamber to the bearing, said plug having a plurality of ports to admit the actuating medium from the feed chamber to the screening chamber, each of said ports being of greater capacity than the nozzle opening, substantially as described. 1

7. In a lubricating device for a turbine such as described, a turbine runner with a driving shaft rotating therewith having conduits therethrough to the bearings therefor, acasing having feed and exhaust heads forming feed and exhaust chambers with ports for the runner, said heads also having bearings for the shaft on oppositesides of the runnerwvith spiral grooves therein, and the feed head a hollow portion extending into the feed chamber with a removable plug forming a screening chamber having a removable screen therein, a removable nozzle forming an opening from the screening chamber to said" conduits, said plug, l1aving a plurality of ports from the feed chamber to the screening chamber, each of said ports being of greater capacity than said nozzle opening, substantially as described.

In testimony whereof, We hereunto affix our signatures in the presence of two witnesses.
