HAND PROPELLED PADDLE BOAT Filed April 20, 1929 2 Sheets-Sheet 2 Patented Dec. 31, 1929 UNITED STATES PATENT OFFICE JOHN HENRY RATHBONE AND HERBERT RA'IHBONE, or srnnrronn, ENGLAND HAND-PROIPIELLED PADDLE BOAT Application filed April 20, 1929, Serial No. 357,671, and in Great Britain May 17, 1 28.

tically uncapsizable, which has absolute freedom in the construction of any portion of parts liable to cause injury to the occupants, which will be easier to operate, which will be more comfortable to the occupants and which will allow each paddle to be operated by a separate person.

According to the invention the boat is constructed with a pointed nose or how, a square stern, a fiat bottom, floor boards, covering all or part of the bottom and bearers, two sets one near the stern facing the bow of the boat andthe other near the bow facingthe stern of the boat, the stern seat bea back rest for such seat, and a separate crank and handle for operating each paddle wheel.

The invention will be described with re'l' erence to the accompanying drawings Fig. 1 is aplan of the boat. Fig. 1 is a plan view of paddle box.

Fig. 2 is a longitudinal section of the boat. Fig. 3 is a transverse section thereof. Fig. 4 is an enlarged perspective view of one of the paddles.

Fig. 5 is an enlarged sectional'view of one form of packing gland for the paddle shaft. Fig. 6 is an end elevation of one of the plates of same. Fig. 7 is an enlarged sectional view of another form of packing gland for the paddle shaft.

Fig. 8 is an end elevation of one of the plates of same. v

The boat is constructed with pointed nose or bow A, a square stern B, a flat bottom C,

forward seat F.

carried by the transverse bearers c and with vertical or approximately vertical sides I) curved from the bow to the stern. A seat E carried on brackets e affixed to the sides of the boat is arranged near the stern and is provided with a back rest E preferably affixed to the sides of theboat. The seat E faces towards the bow of the boat. A second seatF carried on brackets f afiixed to the sides of theboat is arranged near the bow of the boat and the front of the boat forward of the seat F is covered in with boards G to form a forward deck, the edge 9 of which also serves as a back rest for the The bottom 0 of the boat is covered by boards C whichalso cover the transverse bearers 0 and provide a clear space between theseats E and F. The boards extend the whole distance between the seats E and F so that should any water get into the boat it will not come into contact with the occupants.

The seats E and F are wide enough to be each occupied by two persons and as the sides D of the boat are vertical or approx imately vertical there is as much room at the bottom as at the top, thus allowing sufficient space for the le s of the occupants.

Two paddles T1 are arranged one at either side of the boat sufficiently near to the seat E so that they can beactuated by the occu- Each paddle pant or occupants thereof. (see Fig. 4) is constructed with four blades h mounted on a square spindle M.

The blades h are carried in pairs one at each end of a pair of flatmetal strips bolted to the square spindle h. The strips/i. carrying one pair of blades are straight and the strips it? carrying the other pair of blades are bent in the plane of the blades so that they will pass inside the other pair of strips 72. at the centre. The blades h are formed of flat material bolted, riveted or otherwise affixed to the strips. i l

The spindle 7L projects into the boat through the side being circular in cross section at this end and aycrank or handleI-I is attached to the end of the spindle inside the boat. A suitable Water-tight packing or gland is arranged around the spindle 71,

where it passes into the boat to prevent water entering the boat around the spindle.

One form of water-tight packing is shown 5 in Fig? 5 and 6. It comprises a circular plate afiixed to the outside of the boat and having a cylindrical flange is provided with a screw thread on its outer surface, the shaft h passing through the centre of the plate,

and a second circular plate K afiixed to the insideof the boat and having a flange-k the inner diameter of which is the same as the outer diameter of the flange is so that it can be screwed on to the latter. A plug or nut k is screwed into the flange k to compress .thetresilient packing material-K .between it y and the end of the flangek .to form a tight packing around 'theshaft h The ends of i the plug 12 .and flange k adjacent to the m,pack1ug K are preferably chamfered as shown. The plateslK and K arebolted to theside'of the-boatsby the bolts k The watertight packing shown in Figs. 7 and :8 comprises two rectangular plates 1K and with central cylindrical flanges k and k" of equal diameter through which the shaft It passes. A resilient packingK is filace d between the chamfered ends of the anges h" and hiand is compressed by the bolts k which hold the plates k and k in iposition.

The .paddlesHare housed in paddle boxes L which are semi-circular in shape-and are scurried on boards or plate Z projecting outwards from the sides of the boat. These plates or boards-l are connected both at the front and back =.to thesides of the boat by diagonally arranged bars or stays M arranged as shown in either Fig. 1 or Fig. 1 whichserve as buffers to guard the paddles and addle boxes. A convex iron :band M may e arrangedalong-theiedge.ofthe board l-to reinforce it. 7
