I WILLIAM LAWSON of 22 Orchard Street Preston in the County of Lancaster
Machinest do hereby declare the nature of this invention to be as follows:-
My Invention is for the purpose of Raising Lifting, or Hoisting Substances
light or heavy either by hand or other power and will stop firmly at any given
point as soon as the motive power is withheld.
The Apparatus is constructed by an Excentric attached to a handle or pully
working on a Stud which moves a cog wheel too & fro acting upon Cogs inside
a flanged pully to which a rope, Chain, or Strap is attached.
The inside wheel being held in position by a piece attached to the bottom of it,
with a Slot at the other end, which works on a Stud to admit of the too & fro
action And the Apparatus described above I claim as my Invention for which I
apply for a Patent.

page_text: I WILLIAM LAWSON of 22 Orchard Street Preston in the County of Lancaster
Machinist do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
My invention is for the purpose of raising, lifting, or hoisting substances-light,
or heavy, or pressing materials together to check speed and such like action, and
is put in motion either by hand or other power, and will stop firmly at any given
point as soon as the motive power is withheld. The apparatus or machine is con-
structed by an excentric revolving on a stud to which a handle, or pulley with a
face plate is attached which when set in motion moves a cog wheel too and fro
thus acting upon cogs inside a flanged pulley to which a rope, chain, strap or other
appliances is attached. This said wheel being held in its position by the face-plate
and a piece of metal attached to the bottom of it with a slot at the other end
which works on a stud to admit of its oscillating action.
Fig. 1, is the Hoist complete showing all external parts.
Fig. 2, is an outside view of the flanged pulley to which a Rope, Chain, or
Strap is attached.
Fig. 3, is a front view of flanged pulley showing cogs inside which are moved by
the Oscillating action of the cog wheel as illustrated by Fig. 4.
Fig. 4, shows the Oscillating wheel with piece of metal attached to the bottom
of it with hole in centre for the action of the Excentric which Excentric is shown
in Fig. 6.
Fig. 5, shows the back-plate screwed firmly to a piece of wood showing centre stud
position H upon which pulley, excentric, and handle revolve, also stud position for
slot as shown by G in fig. 4.
Fig. 6, illustrates the handle, face-plate, and Excentric; this handle face-plate and
Excentric revolves upon a stud the position of which is shown by H in fig. 5, and the
Excentric revolving in centre of wheel fig. 4 cause it to oscillate so as to catch the
inside teeth in the flanged pulley which cause the pulley to move about one revolution
to 12 revolutions of the handle and Excentric. A in Fig. 1 is the handle and face-
plate to the inside of which the Excentric is attached. B a piece of metal attached to
the bottom of the Oscillating wheel as shown in fig. 4. C stud for slot as shown by G
in fig. 4. D Flanged pulley to which a chain &c. is attached. E, in Fig. 3, hole in
back of pulley for centre stud upon which the pulley revolves. F in fig. 4, hole in
which the Excentric works causing the oscillation of this wheel. G in fig. 4, slot
working on stud C in fig. 1. H in fig. 5, Stud centre in back plate upon which stud
the pulley, handle, and Excentric revolves. I in fig. 5, Stud centre for slot as shown
by G in fig. 4. J in fig. 6 the Excentric.

page_text: The face-plate, handle, excentric, oscillating wheel and pulley are kept in position
on the centre stud by a washer screwed to the outside end of the centre stud. The
fixedness of the pulley when the motive power is withheld is caused in the following
manner. The pulley to which a chain or rope is attached can only be moved by the
Oscillating wheel as shown by Fig. 4; that wheel being made to oscillate by the
Excentric as shown in fig. 6 which excentric depends for its action upon the motive
power supplied by hand or other means.
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 as my
invention is
The general construction of the Machine as described by this Specification, and
Drawings attached
