BOAT.

Specification of Letters Patent.

Patented Apr. 22, 1919.

Application 41106 August 31, 1918. Serial No. 252,277.

To all whom it may concern:

Be it known that 1, .AiDJUmR Lamas Pmmenn 'laLBo'r, a subject of the iflinglof Gcreat Britain, ;residing at Montreal, Glillfldll, have invented certain new and .usefirzl ments in Boats, of which the folzlowing is a specification.

This invention relates to improvements in boats; and its object, briefly stated, is the provision olf a boat which is-ufl3inkmh1e.ean =1f filled with water, and which, by mason'oi its peculiar construction, is practically incapable of being upset, the invention fiunther aiming to provide a boat o f the e specified, the speed of which is in no my retarded by the presence esf the aforesaid improvements. I

An embodiment of the linmtionisnilrlustrated in the accompanying draming where- 1n- Figure 1 is a at; Fig. 2 is a side elevation thcneofpand Fig. 3 is a, cross-section on line AA, Fig. 2.

Referring more partieulamiy to the dmwing, 1 indicates the body of the boat'w lfich, as shown, comprises the oppositely-located, vertical side Walls 2 and 3, and the vertical end walls 2 and 3", the side Walls 2 and 3 being connected at suitable intervals by cross-pieces or seats 4.

At each side of the boat, there is provided a specially-constructed air chamber 5 which is located intermediate the ends of the side wall 2 or 3. Each chamber has its inner side wall formed by the vertical Wall 2 or 3, and has its outer side wall made up of oppositely-slanting upper and lower sections 5 and 5 which are connected by a vertical or perpendicular intermediate section 5 disposed parallel with the side wall 2 or 3. The lower section 5 of this specially-formed outer wall is secured at its bottom edge to the corresponding edge of the adjacent vertical side wall, in some suitable manner, and extends upwardly and outwardly away from such wall, its upper or top edge joining the lower edge of the connecting section 5 The upper section 5 has its top edge abutting against and secured to the upper edge of the said side wall 2 or 3, and is inclined downwardly and outwardly with respect thereto. its bottom edge joinln the top edge of the connected section 5 he end walls of the chambers 5 are formed by substanplan view of the improved tially ll-shaped parts 5' members 5 boat.

provided on the which constitute the ends of the The opposite side walls of these memlbers 5" converge sharply, as shown, thereby giving the boat a pointed shape at both how and stern to facilitate its progress through the water; and said walls are extended rear- Wardly in the planes in which they respectively lie to form the parts 5*, which latter between and are suitably fixed to the adjacent edges of the sections of the outer walls of the air chambers 55, so that each chamber has the general shape of a truncarted, quadrangular prism.

The bow and stern members 5 project an appreciable distance beyond the ends of the body l of the boat, as well as beyond the air chamber 5, and, by reason of their sharplysaid chambers.

It is to be observed that the air chambers are symmetrically constructedand arm ed With respect to the boat, and that their wi th is greatcst at their central portions, the lower sections 5 of their outer side walls being submerged when the boat is in the water, as will be apparent from Fig. 3, wherein the broken horizontal line indicates the water level. Consequently, the greatest content of air in the chambers is located approximately at the water level, so that the boat is thereby given the maximum degree of buoyancy, and is rendered virtually incapable of upsetting, or of being sunk. irrespective of the amount of water which it has shipped. All of the various joints above described are water tight, as will be understood.

The propelling mechanism preferably consists of a plurality of paddles 9 arranged in pairs at opposite sides of the boat and increasing in width from their inner or upper ends to their free outer ends. rigidly fastened at their upper ends in some suitable manner in loops 7 formed adjacent one end of a. set of rods 7. one of such rods being provided for (Zlt'll paddle. (he latter and the rods being disposed at. right angles to each other. These rods T are pivolally mounted intcrnndiatc their ends in pairs of perforated brackets 6 which are secured along the upper edges of the walls 2 and 3; and said rods have their inner ends bent They are llO to form handles 8, and their outer ends turned upwardly. The paddles are shaped or curved in such a manner as to fall at practically a vertical angle over the outer sides of the air chambers 5, as illustrated in Fig. 3.

claim as my invention: 1. A boat comprising a body having vertical side and end walls and a flat bottom; a air of air chambers arranged symmetrically on opposite sides of said body and having their inner walls formed by the adjacent side walls of the body; and V-shaped bow and stern members arranged in front and in rear of the corresponding ends of said body and having extensions which form the end walls of the air chambers and serve to close the same.

2. In a boat, the combination of a body having vertical side and end walls; and a pair of air chambers arranged symmetrically on opposite sides of said bod and having their inner walls formed by t e adjacent side walls of the body, the outer wall of each chamber comprising an upwardly and outwardly inclined lower section socured along its bottom edge to the bottom edge of the corresponding side wall of the body, a downwardly and outwardly inclined upper section secured along its top edge to the top edge' of said side wall, and an intermediate vertical section secured along its top and bottom edges, respectively, of the copies at this patent may 12th day of June,

upper and lower sections, and means for closing the ends of said chambers.

3. In a boat, the combination of a body having vertical. side and end walls; a pair of air chambers arranged symmetrically on opposite sides of said body and having their inner walls formed by the adjacent side walls of the body, the outer wall of each chamber comprising an upwardly and outwardly inclined lower section secured along its bottom edge to the bottom edge of the corresponding side wall of the body, a downwardly and outwardly inclined upper section secured along its top edge to the top edge of the said side wall, and an intermediate vertical section secured along its top and bottom edges, respectively, of the upper an lower sections; and V-shaped bow and stern members arranged in front and in rear of the corresponding ends of said body, each side wall of said members having a V- shaped extension which fits between and is secured to the adjacent end edges of the said sections of the outer wall of the corresponding air chamber so as to close the latter at such end.
