GRIER, OE NORTH HOLLYWOOD, CALIFORNIA, AssioNoR To HAYMO ELECTRIC SPEED BOAT CORPORATION, LTD., or Los IPORATION 0F NEVADA ANGELES CALIFORNIA, A OOR- MOTOR BOAT Tor Original application filed January 11, 1930, Serial No. 420,114. Divided. and this application led Sepf tember 18,1931. serial No. 563,479.

This invention relates generally to motor Vdriven boats of a type adapted for use as cation referred to deals primarily with an l electric drive for such boats `and the arrangement and mounting of thedrive'parts upon the tunnel portion of the hull at the rear thereof; while the present invention is directed particularly to an improved form of top construction for the boat.

The general construction of boatsof the. present type may be described as comprising a hull having a seat containing cock-pit intermediate its ends, the hull being covered with deckingforwardly and rearwardly of the cock-pit. In the course of loading` and unloading passengers from such boats, the latter are drawn alongside a wharf or loading platform, the level of which-ordinarily is somewhat above the top decking surface of the boat, with the result that access to and from the cock-pit of the boat is had by stepping directlyv down into the cock-pit or upwardlytherefrom onto thewharf. -It is a general purpose of the invention to provide a top structure which normally'extends above and covers the cock-pit, but which is readily adjustable topermit loading and'unloading of passengers without interference with the top. In accordance with theinvention I have provided a top structure of a tilting type so arranged and mounted relativeto the-cockpit, that the top may be tilted clear of the cock-pit to permit unobstructed entrance and eXit of passengers. My improved topin its preferred form comprises a frame pivotally supported at the Vrear of the cock-pit, and preferably upon the decking, vand, suitable supporting means for the forward portion of the top at points advanced from Vthe rear pivotal mountings, the forward supports vbeing preferably located in `front of the cockpit. The invention embodies numerous additional features ofimprovement, such for example as vthe particular structural characteristics of my preferred embodiment of the invention.: These, however, as ywell as the more generalcharacteristics of the invention above mentioned, will be most readily understood from the'following detailed description. I:Reference is had throughout the description to the accompanying drawing, in which Fig. l is a longitudinal sectional view showing a boat equipped with my -improved form of top;

VFig. 2 isia front elevational :view of F ig. l, as viewed from the left; and

tional view showing one of the rear pivo-tal supports for the top.

cates'the hull of the boat,the rear bottom portion of ,the hull being formed by a tunnel-- Referring first Vto F ig. 1, numeral 10 indi- Fig., 3 isV an'enlarged fragmentary sc Y shaped casting 11, uponwhich an electric,

motor 12, driving the propeller 13, is mounted. The propeller shaft 14 extends through an elongated bearing portion 15 of the tunnel 1l, and as will be noted, by virtue of the tunnel shaped characteristics of the casting 11, the propeller 13 is substantially entirely contained therein. `The motor 12 is supplied with current-from a storage battery 16, and the operation of the motor in reverse directions is controlled by a 'switch mechanism 17 operated by lever 18Vmounted within the hull at one'side of the cock-pit. `litudder 20, also contained within the tunnel casting 11, nis operated by way of cables21 attached to the steering vwheel shaft 22. VThe various -advantage-s and novel features embodied in the illustrated tunnel casting, and themounting of the? drive :motorand the propeller Y thereon, are fully described in my lcopending application, Ser. No. 120,114 and will re- 'quire no further mention herein. Y

rThe cock-pit generally indicated at 23, and containing the seat 24, is located intermediate the vforward and rear .ends of thehull, the latter being covered by decking 25 andl 26 forwardlyV and rearwardly of the cock-pit. A top structure, generally 1indicated at'27, normally extends horizontally over the cockpit in the position shown, the top preferably being supported both atthe front and rear of the cock-pit, and being tiltable about its are curved downwardly along their rear Vpor-Vv tions as at 28a, and have'suitablepivotal connections at 30 with the decking 26 at the rear of the cock-pit, as will permit rearward tilting of the top. Although in the broad aspects of the invention any suitable type of support for the top at the rear of the cockpitmay behad to permit such t-ilting movement, I preferably utilize the form of support shown in detail in Fig; 3.

' The curved end portions 28a of the side frame rods are inserted within socket sleeves 3l pivotally attached to the decking 26 by hinged connection 32. Rubber buffer rings 33 are placed upon sleeve 31 as protection to the decking when the top is .tilted backA to the dotted line position of Fig. l. As will be seen, the top 27 may he readily disconnected y from its rear support 30 simply byy withdrawjing the side frame rods from theY pivoted socket sleeves 3l. The top frame is covered by a suit-able fabric which is shown to eX- `tend only rearwardly to the' curved portions 28a of the side frame rods, although the covering may be extended further down at the vrear if desired.

rThe forward end of the top" is supported on fa pair of standards havingfootings on a raised floor 36 at the bottom of the hull. Standards 35 have enlarged flanges 37 at their upper ends, and upon which the side rods 28 of the top frame rest substantially at their juncture with the forward transverse frame member 29. From the foregoing it willfbe understood that the.-top `simply rests uponthe upper ends of standards 35, and that the top may bey tilted rearwardly to openly expose the cock-pit, by swinging the top to a position of rest on the rear decking 26 as shownby the dotted lines 27a.l Y

I preferably provide means for releasably securing the top against being tilted backward asa result of wind pressure directed against its'under side. As typical of such means I show a spring pressed latch 38 'adapted to engage a forward projection 39 carried on a rod 4.0 extending between the standards 35 directly below the forward frame member 29. As will be seen, asthe top is swung down to a positionof rest upon vrstandards 35, the latch 38 automatically engages lug 39 to prevent raising of the top -until the latch is manually released. Latch 38 preferably is located centrally of the forward end of the top so as to be `readily access'ible to an attendant on thewharf from either side of the boat. Y
