Year: 1884

page_text: We JAMES WILLIAM ROCKLIFFE 38 Clockwell St West Southwick Sunderland
County of Durham, Ship Yard & Boiler Shop Machine Worker &c and JOHN
GREIG 125 Low Street Sunderland County Durham Tinsmith &c do hereby
declare the nature of the said invention for SECURING SHIP HATCHS BATTENS
TARPAULINS BOATS AND SPARS to be as follows:-
The Invention relates to Improvments in Ships Hatch Clamps or Cleets and
Fasteners combined with Ring Bolt Holes for securing Ships Boats and Spars
unto Ships Hatchs &c. and consists essentially in a Sliding Clamp or Cleet with
the aforesaid Ring Bolt Holes, The Bolt is square or canted to keep all connected
therewith in proper possition It is rounded off at one end to allow it to be screwed
the required distance for a two inch nut, To screw up the parts attached theirto It
as also a drop to it of a required size for Ring Bolt Hole where required and a Slot
Hole for a Steel Wedge to force up the Clamp or Cleet which as a square or canted
Hole through it to fit the said Bolt. It may be made of Steel or other Metal and
Riveted on the Hatch Coamings.
For Locking or securing the Hatchs the Hatch Bar is brought over from Bolt
to Bolt.

We JAMES WILLIAM ROCKLIFFE, 38, Clockwell St West, Southwick Sunderland,
in the County of Durham, Ship Yard, & Boiler Shop Machine worker, &c. and
JOHN GREIG Tin & Coppersmith Bodlewell Lane Sunderland County Durham do
hereby declare the nature of our invention for AN IMPROVED APPLIANCE FOR
SECURING SHIPS HATCH BATTENS TARPAULINS & SIMILAR FITTINGS and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
The Invention relates to improvements in Ships Hatch Clamps or Cleats and
fastners combined with ring bolt holes for securing Ships Boats & Spars unto
Ships Hatchs &c and consists essentially in a sliding Clamp or Cleat with the
aforesaid Ring Bolt Holes, the Bolt which is also a combined Rivet, when used
single (viz) not as a Ring Bolt) square or octagon at the Rivet end which is
fitted into a hole of the same shape to keep all connected therewith in proper
position, And when the two inch nut is used to force up the Sliding Clamp or Cleat,
It is rounded off at that end to allow it to be screwed the required distance, of not
more than five threads to the inch, And where the wedge or Cotter is used which
said Wedge or Cotter will have gauged holes to suit the various thickness of
Battens & tarpaulins the said holes to correspond with those in the Clamp or Cleat
for a Steel pin fastener to go through which Locks the wedge and prevents it being
knocked out by anything washing about the decks. The aforesaid bolt and rivet
combined may not be less than 1 inch diameter up to outside of coaming or similar
structure that it may be secured on to where a corresponding strength is required
and the said bolt is swaged down or reduced as a rivet if single (viz;) without
a rod, shackle or ring-hole it will be a reduced square or octagon at the rivet end.
The square in length about the thickness of the coaming and fitted into a hole of
the same shape, to prevent it from turning over, and the said bolt has slotted holes
to suit the connecting bolt and wedge or cotter. The slotted bolt hole in length
may not be any more than one third of the combined rivet and bolt, and the
diameter of the slotted hole not any more than one third the diameter of the
combined rivet and bolt, on which is fitted the sliding clamp or cleat and batten
fastener and secured by the connecting bolt through the clamp and combined rivet
and bolt attached on to the hatch coaming or similar structures.
The aforesaid
clamp or cleat and batten fastener to be forced up by a wedge or cotter or screw
nut, and when the nut is applied only there will only be one slot hole for the.
connecting bolt, and if no connecting bolt is used there will not be any slot holes,
but the clamp or cleat and batten fastener will be solid all round,

page_text: attached. In reference to figures 1, 2, 3. B, is the coaming of hatch. k is the
combined bolt & ring G. rivetted on at, I, the rivets. H, being the supports or
stays J, is a stud through the combined rivet and bolt. D, the sliding clamp or
cleat. M, the batten fastener. j, is a groove on the inside of that part of the
clamp or cleat which covers combined rivet and bolt and the depth of groove is
about one third the thickness of the clamp on each side, and the said groove when
the said clamp or cleat is wedged up passes over the stud J, and supports the same,
and when not wedged up, by pushing the clamp or cleat in it is locked in an
upright position and out of the way of fouling. E, the wedge or cotter. e the lug.
The object of the lug is to lighten the appearance of the wedge which is of equal
thickness throughout, also to force or knock out the wedge or cotter when required,
and the said wedge or cotter is secured by a chain. F, the pin fastener which is
also secured by a chain, the object of the said pin fastener is to lock or secure the
wedge or cotter from being accidentally knocked out, the wedge is therefore
guaranteed. f. are the holes in the wedge and the sliding clamp or cleat for the
pin fastener to pass through. L, the connecting bolt to secure the clamp or cleat
and batten fastener. The said bolt is fitted through a link of chain from the lug
of wedge and through l, k, l, the clamp and combined bolt and rivet and secured
by link of chain from the pin fastener and by that means the clamp or cleat is
quickly connected and disconnected. C. The tarpaulin. A. the hatch batten,
which being placed in the bight of the tarpaulin as shown in figures 3, 5, 7 and the
sliding clamp or cleat and batten fastener forced in by the wedge or screw nut,
the tarpaulin is then firmly secured, and also the batten, which said batten cannot
be removed by any force of water, which is also guaranteed by the overlap batten
fastener.
Figures. 4, 6. are front elevations wedged and screwed up. Figures. 5, 7. are side
elevations, open. Fig 8, a front elevation wedged up horizontally. In this
instance the clamp or cleat and batten fastener is solid all round and slides in and
out only. Fig: 9. a front elevation shewing methods of arranging the appliance
but this method is not to be considered the one to be adopted for various specimens,
as for instance the sliding clamp or cleat and batten fastener on the single combined
rivet and bolt may by itself be placed at suitable distances apart on the hatch
coaming to be screwed or wedged up as the case may be, or the rod shackle or ring
appliance may intervene at suitable distances, and it is obvious that by the
introduction of the rod by itself, it will more than answer all and every purpose of
the shackle or ring, both as regards handiness for securing purposes and as a
Spanish windlass-and hand rail on high or low coamings for emigrant ships &c.
O, The ring appliance screwed up 6 & 7 without ring screwed up. N, without
ring, wedged and screwed up 4 & 5, without rod and shackle wedged up. R, the
rod. S. the shackle. P. P. the rod and shackle appliance wedged up.

J. the stud. Q. the drop. I, 1. the slot hole. Fig: 11, M. the overlap batten
fastener, j. the groove. the connecting bolt hole. Fig: 12. the connecting bolt.

Having now particularly described the nature of the said invention and the
manner of performing the same. We declare that what we claim as the invention
to be protected by the herein before in part recited Letters Patent, is-
1st In a fastener for ships hatch battens, tarpaulins and similar fittings. The
employment in combination of a bolt on which is a sliding clamp or cleat and
batten fastener forced up by a wedge or screw nut constructed, arranged and
applied substantially as, and for the purposes herein described and shewn in the
drawings.
2nd The combination with the pin fastener of the wedge or cotter and sliding
clamp or cleat and batten fastener with the batten of hatch coaming constructed
and applied substantially as shewn in Figures 1, 2, 4, 9.

page_text: 3rd The combination of a rod and shackle or ring with a bolt attached to hatch
coamings on which is a sliding clamp or cleat and batten fastener forced up by a
wedge or nut constructed, arranged and applied substantially as described and
shewn in Figures, 1, 2, 3, 9.
