IMPROVEMENTS IN PRESSES APPLICABLE ALSO FOR LIFTING HEAVY WEIGHTS
Year: 1885

page_text: JOHN THOMAS MOORE 48 Cemetary Road Crewe Draper do hereby declare the
nature of my invention for IMPROVEMENTS IN PRESSES APPLICABLE ALSO FOR
LIFTING HEAVY WEIGHTS to be as follows:-
Two wedge shaped eccentrics each equal to the sixth part of a circle are used
the round or outer edges of each eccentric are in contact with each other, in the
apex or edge of the wedge shaped eccentrics are pins at the bottom to secure it
to the stand on which it works & at the top to secure the pawl the eccentrics are
each in more or less from the pin to the outer edge further on one side than the
other, thus in the rolling motion back & forward, the pins are pushed further apart
& vice versa a pawl at the top & bottom working in a ratchet utilise the power.
obtained slight modifications adapt this movement for use with the toggle arm
system of press, also as a lifting jack, or for winding up heavy weights it may be
used as a vertical, horizontal or circular motion.

JOHN THOMAS MOORE 48 Cemetery Road Crewe Draper do hereby declare the
nature of my invention for IMPROVEMENTS IN PRESSES APPLICABLE ALSO FOR
LIFTING HEAVY WEIGHTS and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
My Invention in presses for pressing ensilage and other material, for baling, and
also for lifting heavy weights is intended to give a heavy pressure with the
smallest amount of friction it is of great strength and simplicity of construction
and may be applied in place of the screw in toggle arm presses.
The press as used for pressing ensilage, consists of First the bottom or floor
holder this rests on the beams which are placed on the boards covering the ensilage
through which also the bar A passes which is fastened to the bottom of silo or
stack.
2nd The top part or head consists of the upper eccentrics E and pawls G in one
frame also the lever handle I.
3rd Racks B are fixed on each side of the iron bar A into which the pawls in
floor holder and the head, work.
.
4th An iron bar is fixed in the bottom of silo or stack, this bar is perforated so
as to fasten the racks to it, or in the event of continuous pressure being required
the perforations are somewhat closer together say from lin apart the press is then
worked direct from iron bar dispensing with the use of racks.
The construction is as follows Two wedge shaped eccentrics E and F each of
which is longer on one side than the other are used, the round or outer edges are in
contact with each other, at the apex or wedge end of the eccentrics are pins which
secure the bottom eccentrics to the floor holder, and the upper one to the top part
of press.
The floor holder (so called) is made so as to slide freely down the iron bar, it has
two sides and two ends in the sides are placed the pawls H and above them the
lower eccentrics F at one end is also placed an eccentric in an horizontal position D
the round edge of which fits loosely against the edge of the upright iron bar, the
lower side of this eccentric is shorter than the upper one, thus permitting the floor
holder to descend but preventing its rise when pressure is taken away.
The top of press as above mentioned is simply a frame to clip the iron bar, on
the underside of this frame are the two upper eccentrics E one on each side and
above these are placed the two upper pawls G one on each side, a handle or lever
is connected to the two upper eccentrics on the longer side of the eccentrics.
To work the press the two upper pawls are put in contact with the rack, on the
handle being pressed down and the longer sides of the eccentrics pressing or rolling
together, the floor holder is forced down one tooth lower on the rack, the handle
being raised causes the shorter sides to come together, and the two upper pawls
sink one tooth lower, so that the top and bottom pawls sink alternately as the
handle is raised or lowered.

page_text: For pressing and giving continuous pressure without the use of the racks etc as
in the case of a silo having two or more iron bars, the machine being in use upon
one of the bars, a fulcrum is fixed on the floor holder on which a lever pinned to
the bar, rests, the floor holder when pressed down is held in position by the afore-
said horizontal eccentric or a self acting pin may be used.
Having now particularly described and ascertained the nature of my said
Invention and what manner the same is to be performed I declare that what
I claim is
First. In combination Racks Pawls Lever & Eccentrics arranged as aforesaid
and for the purpose specified.
Second. Improved eccentric floor holder for the purpose specified.
Third. In combination as above a simple powerful arrangment for the working of
Cranes Toggle Lever and other Presses.
