TOW SKIFF Filed June 21, 1948 2 Sheets-Sheet 1 J. E. CHRISTIE Oct. 3, 1950 TOW SKIFF 2 Sheets-Sheet 2 Filed June 21, 1948 Patented Oct. 3, 1950 UNITED STATES PATENT oFFxcs 6 Claims.
'I'he present invention relates to a tow ski and it consists in the combinations, constructions and arrangements of parts herein described and claimed.
It is an object of the present invention to provide a tow skiff which is simple in its construction and operation yet effective and efcient in use.
Another object of the invention is the provision of a novel hull structure in a skiif of the character set forth.
Another object of the invention is to provide `a novel crane structure forming a part of the invention.
Another object of the invention is the provision of a craft which is provided with great maneuverability and which may have great util ity as a tugboat.
A further object of the invention is the provision of a novel seagoing craft which is especially adaptable for use in rescue work at sea.
A still further object of the invention is to provide a skiif of the character set forth which is provided with means for encompassing a portion of another craft and with means whereby the latter may be wholly or partially supported.
Another object of the invention is to provide a novel arrangement in a tow skill of a bridge and a power plant both forming a part of thew` invention.
Other and further objects of the invention will become apparent from a reading of the following specification taken in conjunction with the drawings, in which:
Figure 1 is a side elevational view of an ern- ""5" bodiment of the invention,
Figure 2 is a plan view thereof, and
Figure 3 is a front elevational view of the skirt shown in Figures 1 and 2.
Generally there is provided a tow skiif comprising a pair of spaced longitudinally extending pontoons interconnected at their rear ends with a transversely extending plate to thus form a substantially U-shaped enclosure with the open M end thereof at the bow of the skiff. The transof the boat hull and the ends of the transversely extending plate are interconnected with tubular frameworks upon which are supported a fuel tank, tool lockers and the like.
Referring more particularly to the drawings, there is shown therein a tow skiff comprising a pair of spaced longitudinally extending ponto-ons Ill and II which each have their forward `ends provided with bows l2 and i3, respectively and whose rear portions are interconnected by a transversely extending plate I4 upon which lis fastened decking l5. The plate I4 and decking l5 are additionally reinforced by means of downwardly extending front andrea-1' webs A and B respectively, which are suitably secured as by welding, riveting or the like to the inner side walls of the pontoons ID and II. The 4bottom edge of the reinforcing webs is curved as indicated at C and is spaced above the level of the water so as to eliminate any drag or resistance caused by contact with the water during the travel of the skiiT. `The curvature C is designed to allow theiwater to pass under the skiff Vwhen operating in either rough or quiet waters.
Interconnecting each end of the decking l5 and the upper rear portions ofthe pontoonsn Ii] and Il are brace plates I5 and I'I which-are shaped to conform with the contour ofthe upper portion of the pontoons. 3
Supported by tubular legs I 8 afxed to the decking I5 is a transversely extending bridge I9 provided with a ladder 2G communicating with the deck l5. A steering wheel 2l and navigational instruments 22 are situated in the bridge 20.
Base plates 23- and 24 are iixed forwardly on the pontoons I0 and I I, respectively, for the support of pairs of upwardly converging legs 25 and `26, respectively. Amidships on each of the pontoons It! and II is a base plate 2l and 28, respectively, for the support of upwardly converging legs 29 and 30, respectively.
Supported by the upperends of the legs 25 and 26 is a transversely extending beam 3l and supported by the upper ends of the legs 29 and 30 is a transversely `extending beam 32. Interconnecting the centers of the beams 3l and 32 is a longitudinally extending beam 33 centrally disposed upon which is a pulley housing 34 for a hoist.
A winch 35 is aflixed centrally and forwardly on the deck I5 and is provided with a cable 36 and hook 3l.
A boat hull 38 extends rearwardly from the Qelter Q the plate I4, contains a power plant 39 and is provided with a hatch 40 hinged, as indicated at 4I, and provided with a handle 42. A rudder 43 is mounted at the rear of the hull 38.
Interconnecting'the outer ends of the rear wall f the plate I4 and the rear end of the boat hull 38 is a pair of tubular reinforcing members 44 and 45.
A pair of substantially circular frame members 4E and 4'! are connected with the member 45 and with the hull 33 and plate I4, respectively, and support therein a cylindrical fuel tank 48.
Tubular support members 49 and 59 interconnect the member 44 and the plate I4 and the boat hull 38, respectively, and are, in turn, interconnected with a strap 5I and a platform 52 Y upon which is supported a tool locker 53.
While bolts are shown in the drawings for various connections and fastenings of vone part to another, it will be understood that welding, riveting or other means may readily be utilized instead of bolting.
In use it will be apparent that the tow skiif herein described may be used for a variety of purposes. For example a small craft in distress may be wholly or partially lencompassed by the pontoons Ill, II and deck I5 and thereafter be wholly or partially supported by a crane, block 'and tackle or the like suspended from the beam 33 while the stern of the disabled craft may be held against forward lurching by means of the winch 35 through the cable 36 and 31. The elevated bridge allows for a clear perspective of the operation of the skif.
While but one form of the invention has been shown and describedherein, it will be readily apparent to those skilled in the art that many minor modifications maybe made without departing from the spirit of the invention or the scope of the appended claims.
