1 Claim. (Cl. 214-1) The present invention relates to new and useful improvements in hoists for boats to lift and store small boats from the water.

An important object of the invention is to provide a boat hoist adapted for installing on docks to lift outboard or rowboats from the water and to support the same on its side in order that the boat cannot become filled with water, when not in use.

Another object of the invention is to provide a hoist of this character of simple and practical construction, which is strong and durable, relatively inexpensive to manufacture, which may be operated by a single person, and which is otherwise well adapted for the purpose for which the same is intended.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like nlnnerals refer to like parts throughout, and in which:

Figure 1 is a front elevational view;

Figure 2 is a side elevational View; and

Figure 3 is a side elevational view showing the hoist after lifting the boat from the water.

Referring now to the drawing in detail, wherein for the purpose of illustration, I have disclosed a preferred embodiment of the invention, the numerals 5 and 6 designate a pair of posts which are suitably secured in upright, spaced apart relation with respect to each other to the outer edge of a wharf or dock 7. Uprights 8 and 9 are secured to the outer surface of the poles 5 and 6 by bolts or the like 10 to support the uprights in a position extending upwardly above the upper ends of the posts.

Slings 11 and 12 which are preferably constructed of straps of buoyant plastic or other suitable flexible material are attached at one end portion in slots 13 at the lower end portions of the uprights 8 and 9 by at least one of the bolts 10. Cables 14 and 15 are attached, respectively, to the other ends of the slings 11 and 12.

A winch 16 is attached in brackets 17 at the upper portion of the upright 8 and is operated by a crank handle 18 and cable 14 extends directly from the sling 11 to the winch. Cable 15 extends upwardly from sling 12 Patented Apr. 8, 1958 over an upper pulley 19 suitably secured at the upper end portion of upright 9 and then, downwardly from the upper pulley 19 under a lower pulley 20 and from which the cable 15 extends under a pulley 21 which is suitably secured to the other upright 8. The cable 15 then extends upwardly from the pulley 21 to the winch 16 so that both cables 14 and 15 are simultaneously and uniformly wound on the winch.

In the operation of the device, the slings 11 and 12 are lowered into the water so that the same may be floated or otherwise placed under a boat 22. The cables 14 and 15 are then pulled upwardly by the Winch 16 whereupon the boat will be lifted from the water and turned on its side and supported in that position by the slings 11 and 12 in an elevated position above the water, as shown in Figure 3 of the drawing.

Resilient pads 23 are suitably secured to the outer surface of the uprights 8 and 9 and against which the uppermost portion of the boat rests to prevent marring the finish of the boat.

From the foregoing, the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claim.

What is claimed as new is as follows:

A boat hoist comprising a winch attached in an elevated position to a supporting structure, a pair of flexible straps attached at one end to the structure below the winch in spaced relation to each other, and a pair of cables attached to the other ends of the straps and extending upwardly therefrom in spaced parallel relation to each other and connected to the winch for winding thereon, said straps being adapted to extend transversely under a boat for raising and turning the boat on its side against the supporting structure, said straps being constructed of buoyant material and being detachable from said cables for floating into a transverse position under the boat, said winch being positioned in a vertical plane with one of the straps to extend one of the cables directly upwardly from said one strap to the winch, and pulleys on the supporting structure to guide the other of said cables directly upwardly from its connected strap and thence horizontally to the winch.
