TURBINAL SCREW-PROPELLER.

Specification of Letters Patent.

Application filed June 24,1912. Serial No. 705,414.

of which the following is a specification.

lllS invention relates to Improvements inscrew propellers for boats, sh

lps and vessels of every kind, and has for its object'the atof greater speed on waters and a propulsion of water I attain the general objects stated by the,

operation, at the stern, of turbmal screw propellers, consisting of four consecutive true edged sections, and all of which are made of met-a1 of anature and quality, and also made in a size and diameter, that may dlfier accordlng to the size or water craft, the momentum required for its head of like kind propulsion, or the cylindrical f asize and strength proportionate to the weight of the propellers and to the use of the water craft, and are held fast and in place, at their fore end, to the propeller shaft by a two-piece metal shoulder-head firmly secured to the shaft by sunk metal keys, and at their after end to the propeller shaft by a shoulderwith hexagon a erture tting corresponding hexagon sha t end, and by nut and cap at the end of the shaft. All is supported by a hanger attached to the after end of the shaft and to the boat, s ip, or Vessel. The propellers rotate in outward directions from the top of the sec- The combination and attachments Figure 1 shows side view of the assembled sections; Fig. 3 shows )eller section; Fig. 4 shows cap andnut on tfter end of the propeller shaft; Fig. 5 :hows shoulder-head on fore part of proeller and also shows sunk boulder-head, holding it fast to the shaft;

e operation of this pro eller is effected in the same manner as in t e case of other screw propellers, but the potency of the revolutions of this propeller in the water is far greater rapidity in spiral succession, of sections, and the consequent greater utilization of the" water in propulsion by its winding or circling around the fore sections and gradually receding from them without diminishing in force and effect.
