1957 F. R. JARNOT BOAT MOORING DEVICE Filed July 23, 1956 a A m mw a F J v R M M 9m H w 2,808,016 BOAT MOORING DEVICE Frank R. Jarnot, Bridgeport, Conn. Application July 23, 1956, Serial No. 599,527 5 Claims. (Cl. 114-230 This invention generally relates to an anchoring device and more particularly to a boat mooring device especially adapted for attachment to the vertical pier of a dock although the device may be attached to any vertical stationary anchor member projecting above the water level to which a boat may be moored.

In areas having a relatively high tide differential, such as in the neighborhood of 6 to 8 feet difiference between high and low tide, a problem arises as to the mooring of the boat to a dock since it is necessary to leave the line sufiiciently slack to permit rise and fall of the boat with the tide and yet have the line tight enough to anchor the boat sufficiently to prevent accidental engagement with other adjacent boats or obstructions. Accordingly, it is the primary object of the present invention to provide a boat mooring device which incorporates a float mounted in a vertical guide having means for attachment to a mooring line whereby the attaching means will always be disposed substantially at a predetermined level above the water so that the mooring line need only be relatively short for securing the boat in the desired position since the float will rise and fall with the water and maintain a constant relationship with the boat.

Another object of the present invention is to provide a boat mooring device incorporating in its construction a vertically elongated tubular member having a longitudinal slot therein together with a float disposed in the tubular member with the float having a transverse projection at the upper end thereof for engagement with a boat mooring line whereby the scope of movement of the float will be sufficient to compensate for the tide differential in the particular area involved.

Other objects of the present invention will reside in its simplicity of construction, ease of installation, adaptation for its particular purposes and its relatively inexpensive manufacturing cost.

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 numerals refer to like parts throughout, and in which:

Figure 1 is a side elevational view of the boat mooring device of the present invention installed on the vertical pier of a dock;

Figure 2 is a perspective view of the boat mooring device per se;

Figure 3 is a vertical sectional view taken substantially along the plane passing through the longitudinal center of the boat mooring device illustrating the details of construction thereof; and

Figure 4 is a transverse sectional view taken substantially upon a plane passing along section line 4-4 of Figure 3.

Referring, now specifically to the drawings, the numeral 1% generally designates the boat mooring device of the present invention which includes an elongated tubular cylindrical member 12 mounted against the outer surface llnitedStates Patent (3 i 2,808,616 Patented Oct. 1, 1957 of a vertical pier 14 of a dock 16 and the vertical tubular member 12 is disposed so that it extends above and below the water level 18 The tubular member 12 is attached to the pier or piling 14 by employing enlarged eye bolts 20.

The cylindrical tubular guide member is provided with a longitudinal slot 22 therein together with a vertically elongated cylindrical float 24 of flexible plastic construc= tion having a rigid bottom member 26 with an upstanding central boss 28 which is threaded for receiving the lower end of an elongated leg 30 of an L-shaped member generally designated by the numeral 32 having a short upper leg 34 which is threaded for engagement with the inner end of a shank 36 of an eye bolt 38. The inner end of the shank 36 is provided with a peripheral projection 40 and the projection 40 in conjunction with the eye bolt 38 orientate the upper end of the float 24 in relation to the slot 12 thereby maintaining the float 24 in a vertical position in the cylindrical tubular member 12 for guiding the movement thereof. A closure cap 42 is provided on the upper end of the cylindrical tubular member 12 to prevent entry of foreign material into the cylindrical guide and also forming a closure and limit means therefor since the eye bolt 20 may be provided with an omitted portion where it passes the slot 22. Also, a closure device may be provided in the lower end of the tube 12 to prevent unauthorized removal of the float 24 and to prevent the float from dropping out of the bottom of the guide 12 in the event of an abnormally low tide. The closure cap 42 may be removed for permitting removal and inspection or repair of the float 24.

A mooring line 44 may be provided with a snap hook 46 on one end thereof together with a loop 48 on the other end thereof for engaging a chock 50 on a boat 52 thereby simplifying the mooring of the boat since no knots are necessary and no slack is necessary in the line except for that slack usually employed to permit the boat a certain freedom of movement in relation to the deck 16. The length of the tube 12 will be greater than the usual tide differential so that the elevation of the eye member 38 is always the same in relation to the water level thereby simplifying the mooring of the boat 52 and assuring that the boat 52 will always have proper slack in the mooring line.

The foregoing is considered as illustrative only of the principles of the invention. Further, 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 and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

1. A device for mooring a boat alongside an anchoring device comprising a tubular member mounted in substantially vertical position on the anchoring device, said tubular member having a longitudinal slot therein, a float movably positioned within said tubular member, a projection supported on said float and extending through said slot, and means on said projection for attaching a mooring line.

2. A device for mooring a boat alongside an anchoring device comprising a tubular member mounted in substantially vertical position on the anchoring device, said tubular member having a longitudinal slot therein, a float movably positioned within said tubular member, a projection supported on said float and extending through said slot, and means on said projection for attaching a mooring line, said tubular member being cylindrical and being considerably longer than the maximum tide differential, said float being cylindrical and elongated for sliding movement within said tubular member.

3. A device for mooring a boat alongside an anchoring devicecomprising. altubular mernhervmounted in. substantially vertical position on the anchoring device, said tubular member having a longitudinal slot therein, a float movably positioned Within said-tubular member, a projection supported on said float and extendingnthrough said. slot, and means one said projection for attachinga mooring line, saidproiection including an'L-shaped memher having an elongated leg extending longitudinally from the top, of the float andrbeing secured to.the.bottom of the, float, the short leg of said L.-shaped member having an eye member mounted thereon with the. shank thereof extending'through said slot and terminating in a loop and forming the means for attaching-amooring line.

4. A device for mooring a boat alongside an anchoring device comprising a tubular member'mounted in substantially vertical positiomon'the anchoring device, said tubular member having a longitudinal slot therein, afloat movably positioned within said'tubular member, aprojection supported on said float and extending through said slot, and means on said projection for attaching a mooring line, said tubular member being-cylindrical and being considerably longer than the maximum tide differential, said float being cylindrical and elongated for sliding movement within said tubular member, said projection including an L-shaped member having an elongated leg extending longitudinally from the top of the float and being secured to the bottom of the float, the short leg of said L-shaped member having an eye member mount ed thereon with the shank thereof extending through said slot and terminating in a loop and forming the means for attaching a mooring line.

5. The combination of claim 4 wherein said cylindrical tubular member is provided with closure means at each end thereof'for limiting the movement of the float.
