SCOW OR FLOAT FOR HOUSE BOATS AND MEANS FOR PROPELLING SAME.
Floats for House Boats and Weans for Pro-' pelling Same, of which the following is a specification.
The object of this invention is to provide a new and improved type of float or scow which is especia-lly adapted for use in the construction of a house boat.
Anotherobject of this invention is to provide means for propelling the scow or float of the house boat.
These and other objects of the invention will be illustrated in the drawing, described in the specification and pointed out in the claim at the end thereof.
In the accompanying drawing,
Figure 1 is a perspective View of a house boat mounted on the scow or float built according to my invention.
Figure 2 is a bottom plan view of the scow or float showing the propelling means therefor.
Figure 3 is a detail perspective view of one of the propeller paddles and a partial section of the scow in which the paddle is mounted, the parts being viewed from below.
In the several figures of the drawing like reference numerals indicate like parts.
The scow of the boat forming the subject matter of this invention is made shallow so as to have very little draft. For this reason the scow is made up in the form of a float of which the bow and the stern are pointed with the port and starboard sides of the float curved toward the bow and stern respectively.
The under side or bottom of the float is cut away at each side thereof as indicated at 1 and 2 in Figures 1 and 2. The middle of the float is provided at the underside with a series of semi-circular horizontal pockets or recesses 3, 4, 5 and 6. These pockets project from the cut away portion at each side of the float to the middle of the boat and provide housings for the propeller paddles 7, 8, 9 and 10 to partially revolve therein.
From an inspection of Figure 3 which illustrates one of the pockets in detail it will be seen that the propeller paddles are carried on a hub 11 which is keyed to the ver- Specification of Letters Patent. Patgnted June 2'? 1922.
Application filed September 20, 1921.
Serial No. 502,068.
tical shaft 12. The hub and shaft 12 are mounted in suitable bearings provided in the body of the float above and below the pocket. The bottom of each of the pockets may be made integral with the float or it may be formed by a separate plate that is suitably bolted to the under side of the boat to form the extreme bottom thereof.
Each of the propeller paddles is made up of a pair of paddles 14: and 15 which are fastened to the ends of a central shaft 13 at right angles to each other. The shaft which carries the paddles is mounted to rock in the hub 11, through which it diametrically projects so that the paddles are held in place on the hub at diametrically opposite sides thereof.
On the bottom of each of the pockets is mounted the stationary cam 16. This cam comprises a segmental bar having an incline formed at each end thereof. This inclined cam surface projects into the pocket on the bottom of which it is mounted and operates to gradually turn each of the paddles as they come in contact therewith on the rotation thereof. A feathering effect for the propeller paddles is thus secured as follows:
On the rotation of the shaft 12 by means of the worm and screw gearing shown in Figure 3, the hub 11 rotates and with it the paddles l4: and 15. As heretofore pointed out the paddles 14E and 15 are positioned at right angles to each other; that is, when one of the paddles is in a vertical position and presents its flat side to the water the other of the pad dles is in a horizontal position and presents its narrow edge to the water. In this way one of the paddles is forced against the water with its broad side and therefore displaces a maximum amount of water, while the other of the paddles of the same propeller at the same time is drawn through the water edge-wise with a minimum amount of friction therewith.
The paddles are operated so that they are held vertically when they project into the cut away portion on each side of the float and are moved into the horizontal position when they enter into the pockets formed in the middle of the float. Thus when one of the paddles enters one of the pockets it encounters the cam 16 and owing toits previous vertical position strikes the cam with the lower edge thereof. This edge then begins to ride up on the incline of the cam and in doing so gradually turns the paddle from the vertical position to a horizontal position which. it occupies when the paddle has reached a Position. in w ich, t projects to r he iddle of the floatat right angles thereto.
The shaft on Which the paddles are carried is mounted to rock in the hub 11 and While one of the paddles is turned by the earn as it enters the pocket on the under side of the float, the other paddle emerges from the make, was oc s. he s af ns e paddle from the horizontal position Which it dec'upied in the pocket into a vertical positiqn outside "of the pocket In. this Way both of the paddles are gradually and simultaneus y nedYf om. t e r zqnta p i n to 'the vertical position vice versa The paddles of. each of. the propeller paddles thus operate individually in the same, manner; in
which anoar. oi. a rowboat is. operated, in that the Seine feathering of each or the paddles secured through the'turn'ing of oppositely mounted addles placed at opposite angles to each o her in the manner heretof re PQtWQd u The paddles may be driven by any suitable motive power mounted on the float and on the deck of the float may be built any decut away portion of said float, toward the middlethereof, a pair of paddles mounted to rotate ineach of the horizontal pockets, said paddles being mounted diametrically opposite to each other and positioned 180 degrees from each other, said paddles being adapted to alternately project out of said pockets toward the sides of said float on the under side thereof and in the cut-away portions thereof, a cam mounted in said pockets on the bottom and near the inner ends thereof, said cam being adapted to. make contact With one of said paddles of each pair and rock said paddle from the vertical to a horizontal position.

In testimony whereof: I affix my signature.
