We SAMUEL NEWTON and THOMAS NEWTON both of Barker Street Strangeways,
Manchester in the County of Lancaster Mechanical Engineers do hereby declare the
nature of this invention to be as follows:
Our improvements consist, First in an improved arrangement and combination of
machinery for raising and lowering the cage of hoists, and which may be worked
either by hand or power. At the top of the "well" of the hoist in any convenient
position we place a frame or block containing several sheaves or pulleys which frame
is made to rise or fall by two upright screws which revolve in bearings fixed to the
"well" and work into nuts fixed to the frame one on each side-those screws are driven
by the usual driving shaft for driving hoists and geared by bevil wheels or other suitable
gearing to the screws. The screws when in motion, raises or lowers the frame con-
taining the sheaves or pulleys. Above this frame we fix a shaft to the well of the
hoist, on which we place a series of sheaves or pulleys corresponding to those on the
moveable frame. The rope or cord for raising or lowering the cage of the hoist is
attached at one end to a fixture secured to the well of the hoist and above the sheaves
or pulleys, then passes under a pulley on the moveable frame, then over, a pulley or
sheave on the shaft fixed at the top of the well of the hoist, and so on according to the
number of sheaves or pulleys it may be considered advisable to use, after passing over
the last sheave or pulley on the shaft and guided by a carrier pulley if required-it
is then secured to the top of the cage. When the screws are put in motion they raise
or lower the moveable frame according to the direction in which they revolve thus
raising or lowering the cage of the hoist-The length of screws required will be in
proportion to the lift required in the hoist and according to the number of sheaves or
pulleys over which the rope or cord passes in the moveable frame and top shaft.
When driven by power the motion of the screws is reversed by shifting the driving

page_text: straps alternately to the fast pulley, and stopped by shifting the straps on to the loose
pulleys, in the usual manner-and by our.improvement no brake is required.
Our second improvement consists in an improved mode of preventing the cage
from falling, in the event of the rope breaking Immediately below the floor of the
cage we place one or more levers, to one end-which we make the heavy end of the
lever we attach a 'cord, which is carried up through the floor of, or at the back of
the cage and is connected to the lifting rope when the lifting rope breaks, the heavy
end of the lever falls and raises the other end which is made broader with a projection
like a wedge this wedge end of the lever catches betwixt the cage and the framing in
which it slides and thus prevents the cage from falling.

page_text: We SAMUEL NEWTON and THOMAS NEWTON both of Barker Street Strangeways
Manchester in the County of Lancaster Mechanical Engineers 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:-
Our improvements consist in an improved arrangement and combination of machinery
for raising and lowering the cage of hoists and which may be worked either by hand
or power.
In the accompanying sheet of drawings we show our improved machinery as fixed at
the top of the well of the hoist, but it may be placed at the bottom, or any convenient
part of the well, or it may be fixed away altogether from the well and the rope or
chain conducted to the top of the hoist by carrier or guide pulleys and thus on to tho
cage.
Fig. 1 represents in elevation the frame of the well of a hoist in which the cage
slides up and down, and showing a front view of our improved machinery for working
the cage.
Fig. 2 represents a side view of the same, and fig. 3, the plan of a detached part.
The same letters refer to similar parts as shown in the different figures. a represents
the framing of the well of a hoist, in which the cage slides. the cage, e c¹ brackets
bolted or otherwise fixed to the framing a dd screws running in bearings on the
brackets e c', e a moveable frame or block containing, as shewn in the drawing, two
sheaves or pulleys ff" the screws d d work into the block e and the block works in
two slides g g fixed to the brackets c c¹ to keep it steady. When two or more
sheaves or pulleys are used in the block e, we attach to the bracket ca fixing or
tackle in which runs a pulley or sheave i. The rope or chain for raising or lowering
the cage is attached at one end to the bracket c then passes under the pulley of the
block e then over the pulley i in the fixing or tackle then under the sheave or
pulley then up over the carrier pulley ; and down to the
cage ს.
When only one pulley is used in the moveable block e there is no pulley required
in a tackle above, as the rope or chain is then carried direct up from the pulley in the
moveable block to the carrier pulley j and down to the cage b.
The screws are driven by the usual driving shaft for driving hoists, and may be
geared by bevil wheels, as shewn in the drawing fig. 1,- -or other suitable gearing
when driven by power the notion of the screw or screws is reversed by shifting the
driving straps alternately to the fast pulley, and stopped by shifting the straps on to
the loose pulleys in the usual manner well known.
When the screws are put in motion they move the block e to or fro according to the
direction in which they revolve, thus raising or lowering the cage, or, a separate
weight without a cage if required. If two pulleys are used in the moveable block e

page_text: as shewn in the drawing the length of the screw would be one fourth of the lift
required in the hoist, if one pulley, one half, if three pulleys one sixth, and so on.-
By our improvements no brake required and by this arrangement of tackle and
screws, a short screw gives a long lift.
Having now particularly described and ascertained the nature of our said Invention
and in what manner the same is to be performed, we declare that what we claim is :-
The use of a screw or screws working a moveable frame or block containing one or
more sheaves or pulleys for the purpose of raising and lowering the cage of lifts or
hoists, and also separate weights, substantially as set forth and described.
