Self Contained Ship's Hatch Cleat.
WILLIAM WALKER, Junior, 5, Ellenborough Place, Maryport. Cumberland,
Manager, Walker's Ship Repairing Establishment, do hereby declare the nature
of this invention to be as follows:
An excentric clutch or pawl of iron, steel, or other suitable material, the size,
or radii of which may vary to suit position, the hole of which is in an excentric
position, (said hole may be square, octogan, circular, or other suitable shape).
The clutch is fitted into clamp, cleat, bracket or angle iron which is attached
to the coamings of ships, for the purpose of securing the tarpaulins" or other
covering to the hatches, and is operated by being turned over on the spindle
and pressed against the hatch batten" with a key or other lever, and may be
further secured by a ratchet & pawl, or cotter pin, or both. The drawings shew
one mode of application, Fig. 1, is an elevation with clutch fast, Figs. 2 & 4 are
sectional elevations on lines ab, ed, respectively of Fig. 3, Fig. 3 being a
front view with clutch loose.
Ab
E, F, & G, shew sections of ships "coamings," hatch batten & tarpaulin,

Self Contained Ship's Hatch Cleat
1, WILLIAM WALKER, Junior, 5, Ellenborough Place, Maryport, Cumberland,
Manager of Walker's.Ship Repairing Establishment, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement:-
This invention consists of an excentric clutch or pawl fitted into clamp, cleat,
bracket or angle iron, and attached to the vertical sides, or "coamings" of a
ships hatchway, for the purpose of fastening and holding down the tarpaulin, or
other waterproof coverings on such hatchway.
I make the excentric clutch or pawl, as well as the other parts forming the
combination in this invention of iron, steel, or other suitable material.
For the purpose of explaining my invention and so that its application

paulin respectively (all terms well known to seamen) H, clutch, I, spindle for
same, K, cleat or bracket, L, pawl & ratchet, N, check nut, M, cotter pin,
and 0, holes to receive pin, or for the reception of a marlin spike, or its equivalent
when used as a lever in place of a spanner, Fig. 1, shews an elevation of cleat
with clutch fast, Figs. 2 & 4. are sectional elevations of Fig. 3, on lines A, B,
& C, D, respectively, Fig. 3, being a front view with clutch loose, Fig. 5, shews a
form of application in connection with angle iron, Fig. 6, is front view of clamp
with clutch fast, also shewing in elevation and section, a form of hatch batten
with concave front, (also shewn in section in Fig. 5.) which I would prefer to use.
The use of cotter pin is also shewn in Figs. 5, & 6, Figs. 7 and. S are front and
back views shewing pawl & ratchet with teeth the full breadth of shoulder.
I make the excentric clutch which will vary in size or radii to suit position
with a lateral hole to receive the spindle, (said hole may be square, octogan, circular
or other suitable shape) and with a convenient number of holes, O, in its conves
surface, and I may have a pawl L, attached.
The spindle may have a square or hexagon end, to receive spanner, and a check
nut on the opposite end, or one, or both may be left off.
I carry my invention into effect by fixing the same in any suitable manner by
bracket, cleat, clamp, or angle iron to the coamings, and I operate it in the follow-
ing manner, the waterproof covering having been laid over the hatchway the edges
of same drop inside of the cleat or angle iron, the hatch batten (which I would
preferably, but not essentially have made concave on surface as shewn in
Figs. 5, & 6,) is then placed in position and the clutch is thrown over and pressed
firmly against said batten either by a spanner placed on the end of the spindle,
or by a marlin spike, or its equivalent placed into one of the holes, O, and used
as a lever, and it may be further secured by a ratchet and pawl -L, or check nut N,
or cotter pin M, any or either of them, or a combination of any or either of them
as shewn in the drawings.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
;
1. An improved method or means for securing the waterproof covers of ships
hatchways by the construction and application of the herein described self con-
tained ships hatch cleat, and the modifications of the same as herein set forth,
substantially as described and shewn by the accompanying drawings.
2. An improved method or means for securing the water proof covers of ships
hatchways by the construction and use of the herein described combination f
parts, and the modifications of the same as herein set forth, substantially as
described and shewn in the accompanying drawings.
3. An improved method or means for securing the waterproof covers of ships
hatchways by the use of the above described self contained hatch cleat in con-
junction with a hatch batten having a concave surface as shewn in Figs. 5, & 6,
substantially as described and set forth.
