Improvements in Apparatus for Hoisting and Lowering Purposes.
We, CHARLES HENRY SIDEBOTHAM, of 3, Macdonalds Lane, Corporation Street,
Manchester, in the County of Lancaster, Agent, and ROBERT BOND SIBBALD, of
36, Highfield Street, Hightown, Manchester aforesaid, Plasterer, do hereby
declare the nature of this invention to be as follows:-

Our said invention relates to apparatus used for hoisting and lowering goods
to or from the upper stories of buildings. Under our invention we provide a
cathead" which can be readily secured in position. The cathead
desired be permanently secured, or under our invention can be easily fixed, in
position and removed so as to be suitable for temporary hoisting tackle for use
during the construction of buildings. We prefer to form the cathead of suit-
able metal cast or built up to the required shape.
The cathead, as usual, projects beyond the wall of the building and is formed
at its inner end with a horn curving upwards and outwards. The lower part
of the horn is formed with a square or other suitably shaped recess. Across the
door-way or other opening in the side of the building and conveniently near
the top of the same we secure a cross stay of channel iron, or it might be of
wood. The recess on the under position of the curved horn sits upon the cross
stay and a wedge sliding in ways in the upper part of the horn is driven home
between the horn and the top of the framing of the door way. The cathead is
thus firmly secured in position. Instead of having the winding pulley mounted
in fixed bearings as usual at the end of the cathead, we mount the winding
pulley bracket so as to be capable of running in and out upon the cathead. To
effect this we form the cathead with a rail upon which runs a pulley which
carries the winding pulley bracket.
This bracket also carries a detent which engages with a notch at the end of
the cathead so as to maintain the winding pulley in its position for hoisting.
To an arm formed on the winding pulley bracket we also loosely pivot a
pendent catch which on the load being hoisted to its full height is swung
aside by a ball or tappet secured to the winding rope or chain.
As the ball or
tappet is raised above the pendent catch the latter swings back and will thus
engage with the ball or tappet and support the load. The detent being then
released by means of a cord or chain the pulley on the rail runs down the
cathead, which is suitably inclined, bringing the load within the room when the
detent engages with another notch in the cathead. The pendent catch is with-
drawn and the load can then be lowered and released.
By pulling on the detent cord the detent is released and by means of the
cord the winding pulley bracket can be again run out to the end of the cathead
when the detent engages with the notch and secures it in position.
The pendent catch for supporting the load may be applied to existing cranes.

We, CHARLES HENRY SIDEBOTHAM, of 3, Macdonalds Lane, Corporation Street,
Manchester, in the County of Lancaster, Agent, and ROBERT BOND SIBBALD, of
36, Highfield Street, Hightown, Manchester aforesaid, Plasterer, 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 and accompanying drawings:-
Our said invention relates to apparatus used for hoisting and lowering goods
to or from the upper stories of buildings.
In the accompanying drawings to which we will refer,

Figs. 4 and 5 are diagrams representing a detail of our invention.
Under our invention we provide a
cathead" a which can be readily secured
in position. The "cathead" a may if desired be permanently secured, or under
our invention can be easily fixed in position and removed so as to be suitable
for temporary hoisting tackle for use during the construction of buildings. We
prefer to form the cathead a of suitable metal cast or built up to the required
shape.
A suitable section of cathead is shown at b Fig. 1.
The cathead a, as usual, projects beyond the wall of the building and is formed
at its inner end with a horn a¹ curving upwards and outwards. The lower part
of the horn is formed with a square or other suitably shaped recess c.
Across the door-way or other opening in the side of the building and con-
veniently near the top of the same we secure a cross stay d of channel iron, or
it might be, of wood as shown in the drawings. The recess on the under posi-
tion of the curved horn a' sits upon the cross stay, and bolt holes a² are pro-
vided to bolt the horn to the framing of the door, or a wedge sliding in
ways in the upper part of the horn may be driven home between the horn a
and the top of the framing of the door way. The cathead a is thus firmly
secured in position. Instead of having the winding pulley e mounted in fixed
bearings as usual at the end of the cathead, we mount the winding pulley
bracket so as to be capable of running in and out upon the cathead. To
effect this we form the cathead with a rail a upon which run the pullies g g
which carry the winding pulley bracket f.
This bracket f also carries a pivotted detent h which engages with a notch h¹
at the end of the cathead a so as to maintain the winding pulley e in its position
for hoisting.
As
To an arm formed on the winding pulley bracket f we also loosely pivot a
pendent catch or hook i which on the load being hoisted to its full height is
swung aside by a ball j or tappet secured to the winding rope or chain k
the ball is raised above the pendent hook i the latter swings back and will
thus engage with the ball j and support the load. The detent being then
released by means of a cord or chain guided by pullies m by the attendant in
the room to which the goods are to be hoisted, the pullies 9 on the rail run

and secures it in position.
The pendent catch for supporting the load may be applied to existing
cranes or pullies.
In Figs. 4 and 5 I show a method of automatically withdrawing the pivotted
hook from beneath the ball j and at the same time locking the winding
pulley e. The pivotted hook is provided with an extension which, on the
winding pulley bracket f reaching the end of its run, comes into contact with a
stop on the cathead a whereby the hook i is turned on its pivot and removed
from beneath the ball as shown in Fig. 4. The extension is formed with a
jaw which then embraces the pulley e the revolution of the pulley e bringing
pins o attached to or formed on the pulley e, upon the jaw. The load can
thus be lowered against the frictional resistance of the locked pulley e which
puts a drag upon the rope. Similarly on pulling out the winding pulley
bracket so long as a downward pull on the rope as shown by the arrow Fig. 4
is exerted, the pulley e remains locked so that the rope k with empties or with a
load can be lowered against the friction of the locked pulley c. Immediately a
pull is exerted upon the winding rope in a contrary direction to the arrow
to hoist, the pins o are removed from the jaw and the pivotted hook i swings
free
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:
1
1) The improved apparatus for hoisting and lowering purposes arranged and
acting in the manner and substantially as described and shown.
2) An apparatus for hoisting and lowering goods consisting of an inclined
cathead, a winding pulley carried by a bracket arranged to run upon the cat-
head, a pivotted catch or hook to support the load, a cord or chain for travers-
ing the winding pulley bracket outwards and for releasing a detent for locking
the winding pulley bracket, substantially as described and illustrated.
3) In apparatus of the indicated nature a travelling winding pulley bracket
provided with a pivotted hook to support the load substantially as described
and shown.
4) As means for supporting the load in hoisting tackle, a pivotted hook or catch
used in combination with a ball or part secured to the winding chain or rope in
the manner and substantially as described and illustrated.
