IMPROVEMENT IN HORIZONTAL SCREW-PROPELLER'S.
Specication forming part of Letters Patent N o. 184,102, dated November 7, 1876; application led August 28, 1876.
To all whom it may concern:
Be it known that I, WILLIAM S. MYERS, of Southington, in the county of Hartford and State otl Connecticut, have invented a new and Improved Propeller, of which the following is a specification:
In the accompanying drawing, Figure 1 representsa top view, and Fig. 2 a vertical longitudinal section on line c c, Fig. 1, of my.
' an inclosing-casing, B, the screw being app lied to a vertical shaft revolved by suitable power. The screw is arranged. below the water-line. In the case of a, canal-boat, or other small boat, a screw would be located on both the larboard and starboard sides, but in larger vessels one large screw may be located amidships.
An additional channel orume, C, in front `thereby the propulsion of the vessel.
of casing B, ascends gradually from the bottom of the hull to the upper part of the casing, and conducts the water to the screw, While an exit channel or Hume, D, back ofthe casing, forces the water from the lower part oi' the easing, after it has been worked upon by the screw to the outside, and produces The agitation of the water by the screw, being confined into the casing and flumes, will not produce any washing ot banks when used in canals, being also adapted for vessels of war, which require protection for the screw, and to vessels plying in shallow rivers 'and waters. I am aware turbine-wheels or equivalent propellers have been arranged with one side projecting into a channel or passage leading out at the stern of a vessel, but I do not claim such construction and arrangement.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination of the upwardly-inclined passage C, the horizontal screw arranged below the inner or discharge end ofthe same, and the outlet D communicating with the lower portion of the casing B, as shown and described, for the purpose specified.
. WILLIAM S. MYERS.
