Referring in detail to the drawings, the numeral 10 indicates a conventional sailboat which includes the usual mast 11, jib 12, main sail 13, boom 14, and main sheet 15.

According to the present invention there is provided a sheet cleat which is indicated generally by the numeral 16, and as shown in FIG. 3 for example, there is provided a pair of spaced apart brackets 17 which each have a substantially L-shape, and each of the brackets 17 embodies a horizontally disposed section 18 that is secured in place to the lower surface of the boom 14 by means of securing elements or screws 19. Each bracket 17 further includes a vertically disposed section 20, and the numeral 21 indicates a rod or pin that extends between the sections 20 of the pair of brackets 17 and which is Isupported thereby.

The sheet cleat 16 is shown to include a support member that is indicated generally by the numeral 22, and the support member 22 embodies a top portion 23 that is mounted on the rod 21, and the top portion 25 is interposed between the vertical sections 20 of the brackets 17. The support member 22 further includes a depending wall portion 24, and the numeral 25 indicates a pulley or sheave that is journaled to or rotatably connected to the wall portion 24 by means of a pin or securing element 26. As shown in FIG. 3 for example, the outer periphery of the pulley 25 is provided with an annular groove 27 for engagement by a portion of the sheet 15.

The numeral 2S indicates a lever that is pivotally connected to the wall portion 24 of the support member 22 by means of a pivot pin 3l), and the lever 28 is shown to comprise a pair of spaced parallel plates 29 of generally triangular shape or formation, and a pair of spaced parallel pins 31 and 32 extend between the lower portions of the plates 29 and are connected thereto. A portion of the main sheet 15 projects between the pair of plates 29 and extends between the pair of pins 31 and 32, as for example as shown in FIG. 3.

The sheet cleat 16 further includes a movable block or wedge 33 which is shaped to include a tapered portion 34 that has teeth 35 on the lower surface thereof for selectively engaging the portion of the sheet 15 that is arranged in engagement with the groove 27 of the pulley 25, as for example when the parts are in the locked position of FIG. 3. There is provided in the lower porltion of the wedge 33 a slot 36, and the numeral 37 indicates a pin or stud which is connected to the upper ends of the plates 29, and the stud 37 is arranged in engagement with the slot 36 of the wedge 33. The numeral 38 indicates a holding member or element which is in the nature of a pin that is connected to the wall portion 24 of the support member 22, and there is provided a spring member 39 which provides a catch for coaction with the holding element 38. As shown in FIG. 7 for example the spring member 39 includes a portion 40 which is connected to Ian end of the wedge 33 by means of a screw or securing element 41, and the spring member 39 further includes a portion 42 which is provided with an offset section'43 that defines a shoulder that is adapted to selectively engage the holding element 3S.

From the foregoing, it is apparent that there has been provided a sheet cleat for use with a sailboat or the like,

3 and in use with the parts arranged as shown in the drawings, it will be seen that the cleat 16 is adapted to be mounted below an intermediate portion of the boom 14, and the brackets 17 of the cleat are fixed in place to the boom 1d by means of the securing elements such as the vscrews 19. The support member 22 has its top portion 23 supported on the rod 21, and the pulley 25 is rotatably connected to the wall portion 24 of the support member 22 by means of the securing element 26. The lever 23 which includes the pair of plates 29 is pivotally connected lto the wall portion 24 by means of a pivot pin 3G, and

the stud 37 carried by the upper end of the lever 2S is arranged in engagement with the slot 36 of the shiftable or movable wedge 33. A portion of the sheet or line 15 is trained over the grooved portion 27 of the pulley 25, and the sheet 15 is extended or projected between the pair of plates 29 and between the pins 31 and 32, as for example as shown in FIGS. 2 and 3. With the parts arranged as shown in FG. 2 it will be seen that the teeth 35 of the wedge 33 are out of engagement with the sheet 15 so that adjustment of the sheet 15 can be readily effected, and with the parts arranged as shown in FIG. 3 it will be seen that a locking action takes place between the teeth 35 and the portion of the sheet 15 on the pulley 25.

The parts can be made of any suitable material and in different shapes or sizes.

The sheet 15 is adapted to consist of a rope or line that is attached to the lower corner of the sail and the sheet is adapted to be shortened or slackened in the usual manner to control the set of the sail.

According to the present invention there has been provided an automatic sheet cleat which is adapted to be mounted on the under side of the boom 14 between the operators normal operating position and the mast 11, and this permits the device to respond to the same hand part of the main sheet motion on any point of sailing. The main sheet 15 is adapted to extend aft to the boat transom, as for example as shown in the left side of FIG. 1, and the spring member 39 includes the shoulder 43 which functions as a safety catch for coaction with the holding element or pin 38. FIG. 2 shows the automatic sheet cleat open, and FIG. 3 shows the device closed. The portion of the main sheet 15 as for example which is arranged below the cleat 16 is the hand part of the main sheet and this portion of the main sheet which is indicated by the numeral 44 can be manually pulled or directed in any direction from aft to down, so that release of the main sheet can be readily accomplished. Whenk vthe operator leads, directs or pulls the hand part 44 of the main sheet 15 in any direction from aft to downward, the main sheet presses against the pin 31 and pulls the toothed wedge 33 away from the pulley 25 and main sheet 15 so as to permit the main sheet 15 to run free. The safety catch 39 engages the holding element or pin 38 and holds the toothed wedge 33 away from the pulley and main sheet.

This prevents accidental locking of the main sheet. The operator must move the hand part 44 of the main sheet forward to release the safety catch. The hand part 44 of the main sheet 15 can be led, pulled or directed forward so as to lock the main sheet.

When the operator leads, directs or pulls the hand part 44 of the main sheet forward or towards the mast or stem, the main sheet applies pressure on the pin 32 of the lever 23 and pulls the toothed wedge 33 against the pulley 25 'Y and mainr sheet 15. The toothed wedge 33 is shaped so that the main sheet is engaged in the toothed wedge which is pulled home. The harder the pull of the sail on the main sheet, the more positive the hold. The toothed,

a means of controlling a line such as a main sheet instantly securing the line against a sheave or instantly releasing the line so as to permit the line to run freely In addition the present invention provides a means of securing or releasing a line such as the main sheet against a sheave with minimum linear travel of the line at the time of securement or release of the line. In addition the present invention provides a means of holding a line such as the main sheet in a position so as to be always ready and available for instant control of the line, and the present invention also provides a means of preventing accidental securing of a line such as a main sheet.

The automatic sheet cleat of the present invention provides an instant action cleat for a line such as a main sheet, and it'also provides instant infinitely variable adjustment to and from of a line such as a main sheet, and also provides teeth and a wedge having a tapered or angled portion and a securing mechanism to match materials used for construction of the same and materials used in lines by those who practice the art of sailing. Also the present invention embodies a selfaenergizing lock for holding any setting that is chosen for a line such as a main sheet under tension, and there is also provided a positive holding action that operates at exact position chosen by the operator with absolute minimum give before lock is achieved so as to provide a micrometer adjustment of a line such as a main sheet. In addition the present invention provides a highly convenient means for the operator of a sail for performing his duties of sail adjustment, and the present invention also provides a means of securing a line such as a main sheet without cluttering the deck or marring the same thereby with deck mounted cleats. Also there is provided an adjustment of a line such as a main sheet without possible tangling of the spare line and accidental mistakes arising therefrom, and there is also provided a means of operating a line such as a main sheet without ever having to observe the mechanism or even feel the same for getting any setting desired soV as to make it possible for the operator to keep his attention and eyes focused on other action or duties. Furthermore the present invention provides a means of utilizing the energy or pull in a line such as a main sheet to activate a holding mechanism to positively secure ,a line such as a main sheet, and the present invention also provides a cleat such as a main sheet cleat which is fastened immediately to and under the boom swiveling on its hinges to permit proper and instantaneous adjustment of a line such as a main sheet on any point of sailing, and the present invention also provides a means of using gravity to assist the toothed wedge in the initial motion of securing a line such as a main sheet.

It is desired to emphasize the safety features in the use of the sheet cleat of the present invention, and an important feature of the cleat is to help prevent unnecessary capsizing and swampings of sailboats. The sheet cleat will increase the safety factor in the use of the sailboat. For example, in the event of a sudden knockdown or potential capsize from an extremely strong gust Vof wind, the natural human reaction is to grab the main sheet and uncleat it. The time delay between the strong gust and the uncleating of the main sheet with any other type cleat, many times, allows the vessel to go out of control. Because of the construction and design of this cleat, any time the main sheet is in routine or normal use, the main Vsheet is automatically in the free to run position and t instead of a capsizing, the main is started, relieving the turning moment, thus preventingV aducking or possible loss of life. An abnormal motion must be used to cleat the main, any normal motion relieving the main. Holding the main in the hand causes the self-energizing force to the main sheet torrelease the wedge, allowing the main sheet to be ready to run free if the operator so desires. TheV lever operated wedge action isY so quick that the capsizing hazard is greatly reduced.V Y

As shown in the drawings, the wedge is only a fraction of an inch from jamming the main sheet, even though the main sheet is free to run. This cleat is in fact believed to be the safest main sheet cleat device in existence. The cleat of the present invention is capable of different uses as, for example, is readily adapted for use on jibsheets, halyards, lanyards, boomjacks, and centerboard pennants, with the same instantaneous micrometer control.

Minor changes in shape, size and rearrangement of details coming within the eld of invention claimed may be resorted to an actual practice, if desired.
