PROVISIONAL SPECIFICATION.
Improvements in Blocks for Boat Lowering and similar Gear.
I, HUGH RAMSAY, of the firm of Hugh Ramsay & Co., of 29 Main Street,
Greenock, in the County of Renfrew, Ship Block Manufacturer, do hereby declare
the nature of this Invention to be as follows:-
This Invention has for its object to provide blocks of improved construction
for boat lowering and similar gear which shall not be liable to get out of order
and prevent free running of the ropes and consequent risk of loss of life.
The improved block which is of the usual external contour instead of having
the divisions between the pulleys made of wood which is liable to warp is made
with dividing plates of malleable cast iron or steel, the plates having each an
crifice serving as a bearing for the pin or spindle on which the pulleys or sheaves
run these being provided with roller bearings. The sides of the block are bound
together with suitable distance pieces separating the division plates and closing
the ends of the block to which the ordinary shackles or bolts are attached in the
usual way.
Dated this 7th dow of August 1806
