Application filed February 29, 191?. Serial No. 680,740.

Toall whom it may concern Be it known that I, WILLIS HARcRovE, a citizen of the United States, residing at Blocton, in the county of Bibb, State of Alabama,

5 have inventedcertain new and useful Improvements in Steamships; and I do hereby declare the following to be a full, clear, and

' exact description of the invention, such as will enable others skilled in the art to which 9 it appertains to make and use the same.

This invention relates to new and useful improvements in steam ships.

An object of this invention is the provision of a steam ship having a novelly constructed 5 hull of such nature as to relieve the water pressure thereon.

Another object of this invention is the provision of a steam ship having a hull comprising a pair of spaced sections and means 9 for propelling the same located in the space between said sections.

A further object of this invention is the provision of a steam ship such as described which will be comparatively simple and in- 5 expensive to manufacture, reliable and eflicient in use and readily operated.

With the above and other objects in view, this invention resides in the novel features of construction, formations, combinations and arrangements of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which Figure 1 is a side elevation of my invention. Fig. 2 is a longitudinal sectional view thereof. Fig. 3 is a transverse sectional view taken on the line 3-3 of Fig. 1, and Fig. 4 is a transverse sectional view taken on the line 4-4 of Fig. 1.

Referring to the accompanying drawings by similar characters of reference throughout the several views, the numeral designates generally my improved steam ship which comprises a hull 11 consisting of a pair of upper and lower sections 12 and 13. L5 The lower section 13 comprises a deck 14 and a b0ttoml5 curved in the usual manner and having opposite sides connected thereto by the usual longitudinally and transversely extending ribs 17 and 18, respectively. A plurality of vertically extendingstandards 19 are secured within the lower section 13 of the hull and extend upwardly through the deck 14 as clearly illustrated in the drawings. The section 12 comprises a deck 20 and a bottom 21 connected by the usual sides 22 which are curved toward their op osite ends to conform to the curvature of t e sides of the lower section 13.

The deck and bottom 20 and 21 are formed with alining openings through which are extended the standards 19 and connected by the usual braces 23.

A plurality of standards'24 are secured to the opposite sides of the bottom 21 and extend upwardly through openings formed in the deck 20. These said standards 24 are suitably connected to the sides 22 of the deck 12 by brace rods 25. An upper deck 26 is secured to the intermediate portions of the standards 24 and upper portions of the standards 19 and extends substantially parallel to the deck 20. A top 27 runs in parallel relationabove the deck 26 and is secured at its opposite end to the adjacent terminals of the standards 19,

while slanting downwardly from the opposite ends of the top 27 are inclined tops 28 which are secured to the intermediate portions of the standards 24 slightly above the adjacent ends of the deck 26. The bottom '21 at intervals throughout its length is formed with a plurality of longitudinally extending slots 29 through which extend propeller wheels 30 which are keyed upon shafts 31 journaled in suitable bearings 32 secured to the upper face of the bottom 21. These propeller wheels 30 are operatively connected as indicated by the numeral 32 to an engine 33 by means of which a rotary movement is imparted to the propeller or paddle wheels for the purpose of driving the vessel.

When the hull 11 is immerged in the water the line of the latter will at all times remain slightly above the upper side of the wheels 30 as indicated by the dotted line 34 vupon Fig. 1 of the drawings.

From the foregoing disclosures taken in connection with the accompanying drawings it will be readily seen that a vessel of the nature described will be provided for which will fulfil all of the necessary requirements of such a device.

It should be further understood in this connection that various minor changes in the details of construction may be resorted to within the scope of the appended claims without departing from or sacrificing any of the advantages of the invention.

Having thus fully described this invention what I claim as new and desire to by Letters Patent, is:

1. In a vessel of the class described the combination of a completely submerged hull, a surface hull, means ri idly maintaining the two hulls in spaced re ation, the surface hull having a series of slots formed in the protect bottom thereof, a paddle wheel workingdiln' e each slot, andmeans for driving the pa wheels. I 2. The combination with a submerged hull, of a surface hull having a series of slots formed in the bottom'portion thereof, means connecting the submerged hull and surface hull in spaced relation, 9. series of.

dle wheels.
