Other Motive Power.
We RICHARD LONGDEN HATTERSLEY, of Keighley in the County of York, Machine
Maker, and ROBERT HALL of the same place Machine Broker do hereby declare the
nature of this invention to be as follows, that is to say:-
It consists of improvements in means for operuting derrick-cranes by steam
or other motive power in such a manner that from one and the same source,
several cranes may be operated at one and the same time, or all or any one of them
may be disengaged for the purpose of being manually operated.
This is attained by mounting a disc or circular plate on any one of the horizontal
shafts usually employed in the crane, such as the one used for obtaining the "slow"
speed of the winding drum. The said dise being mounted by a suitable key-way or
feather on said shaft so that it may slide lengthwise on same, but when turned or
revolved it will impart its revolving motion thereto. Mounted but to revolve loosely
on same shaft is another disc to which is attached a bevil wheel into which gears
another bevil wheel carried by, and rigidly attached to the lower or bottom end of an
upright shaft. This said upright shaft being placed centrally in the crane so that the
whole of the parts may be revolved or turned around it for purposes well understood.
The said upright shaft carrying at its upper end a suitably shaped pulley or drum
which may be operated upon by a rope or belt from any motor as will be readily
understood, it will be seen that by the discs above named being brought or pressed
into contact with each other, the surfaces of which are suitably prepared, the winding
drum of the crane will be put into operation, or by these discs being separated such
operation will be discontinued.
For putting the said discs into and out of connection or contact with each other, a
groove is formed around the boss of the slidable disc, so that the forked end of a
forked lever may lay hold thereof to operate in a manner well understood, the other
end of said forked lever being manually operated by a hand wheel and screw.
To obviate the friction caused by the boss of the bevil wheel being pressed against
the bearings of the horizontal shaft, when the discs are pressed into contact with each

page_text: other, a hoop is loosely mounted on said shaft between the bevil wheel and the shaft's
bearing, and in said hoop are mounted, in a suitable manner an appropriate number
of antifriction bowls.
Respecting the brake mechanism used in connection with the foregoing arrange-
ment of parts, a friction pulley is attached to or formed on the end of the winding
drum, around which passes a strap the ends of which are operated upon, one by a
"left" the other by a "right" handed screw formed on a shaft which operated by a
hand-wheel. Or the friction pulley may be mounted on any one of the horizontal
shafts as may be desired. However the former arrangement is preferable to the latter
as it allows a clutch box to be used on the end of the winding drum, which (said
clutch box) may be thrown out of gear for the purpose of lowering without all the
motor parts being put into operation.
Since the above described arrangement does not interfere with any of the parts
usually employed for manually operating the cranes, it will be seen that when they
are disengaged the said cranes may still be so operated.
Again as the arrangements above described are in excess of the gearing and other
parts usually employed it will easily be understood that the desired motion for
raising and lowering the "gib "as well as for raising weights as before described,
may be obtained.
Should it be desirable to impart a quicker or slower motion to the winding drum
inan the one above described, an additional friction plate or disc and bevil wheel with
its disc may be placed on the horizontal shaft as above described, but on the other or
opposite side of the upright shaft, by which means, when these parts are put into gear,
the said horizontal shaft is driven in a contrary direction to the one above named
thus allowing another set of gearing to be inserted between said shaft and the winding
drum.

page_text: Improvements in Means for Operating Derrick-cranes by Steam or
other Motive Power.
We, RICHARD LONGDEN HATTERSLEY of Keighley in the County of York, Machine
Maker, and ROBERT HALL of the same place, Machine Broker 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, that is to say:―
It consists of improvements in means for operating derrick-cranes by steam
or other motive power in such a manner that from one and the same source,
several cranes may be operated at one and the same time, or all, or any one of them
may be disengaged for the purpose of being manually operated.
In order that our said invention may be more readily understood we have hereunto
appended sheets of drawings illustrative thereof, to which reference, by figures and
letters, is made in the following description―
Figs. 1 and 2 are side and front elevations, respectively, of a derrick-crane with our
improvements applied.
Figs. 3 and 4 are front elevation and plan, respectively (enlarged scale) of portions
of our improvements. Fig. 5 is a side view of the driving mechanism.
Figs. 6 are 7 are detail drawings, about one third the actual size, of parts hereinafter
described. Figs. 8 and are front and side views, respectively, (same scale as figs. 3
and 4) of modified arrangements of parts. Figs. 10 and 11 are sectional and front
elevations, respectively, shewing the brake mechanisms. Fig. 12 is a sectional detail
drawing hereinafter referred to.
Similar letters refer to similar parts throughout the several views.
The object of this invention is attained by mounting a disc or circular plate a (see
figs. 3 and 4) on any of the horizontal shafts usually employed in the crane, such as
the shaft b which is the one used for obtaining the "slow" speed of the winding
drum c (fig. 9).
The disc a is mounted by a suitable key-way or feather on said shaft b so that it
may slide lengthwise on same, but when turned or revolved it will impart its
revolving motion thereto. Also mounted (but to revolve loosely) on said shaft bis
another disc d to which is attached a bevil wheel e into which gears another bevil
wheel carried by, and rigidly attached to the lower or bottom end of the upright
shaft g.
This upright shaft 9 is placed centrally in the crane so that the whole of the
moveable parts of the crane may be revolved or turned around it for purposes well
understood. The upright shaft 9 has rigidly mounted on its upper outer end, which
projects beyond the upright has also the guys or stays kk, a suitably shaped pulley
around which is made to pass the rope m through which from any suitable motor said
pulley is operated. Instead of the pulley and the rope m being employed, a
suitably shaped flanged drum and a belt may be used as will readily be understood.

page_text: From this it will be seen that by the disc a being brought or pressed into contact with
the disc d the surfaces of contact of which are suitably prepared (as by one being
polished and the other being covered with leather), the shaft 6 will be revolved, by
which, through the gearing shewn by fig. 5, the winding drum c will be put into
operation, and also that when these discs are separated said operation will be
discontinued.
For putting the said dises a and d into and out of connection or contact with each other, a
groove is formed around the boss of the disc a, so that the forked end of the lever n
may lay hold thereof to operate in a manner well understood, the other end of said
lever n being operated by the screw upon which is mounted the hand wheel p.
In order to enable the operator to vary the speed of the winding drum cas is from
time to time found necessary, additional discs a¹ and d and bevil wheel e may be
mounted on the shaft b, by which means, when these are put into gear with the wheelf,
said shaft is driven in a contrary direction to the one above described thus
allowing another set of gearing to be inserted between said shaft band the drum e, which
gearing may be to impart quicker or slower motion thereto as may be desired the
same being arranged in the manner common and well understood.
The discs a, a, d and d¹, may be substituted by the bush or drum and the
wheels ss, said drum being made to taper each way from about its centre part, the
same being made to enter the tapering hollows formed on the faces of wheels s s¹
(see fig. 12) respectively, so that when manually operated by a forked lever entering
the groove tas is well understood, it is only necessary to move said forked lever in
one direction to put one wheels or sin gear, and the other to put the other wheel
sors in gear; the place about midway between the two being its place of rest.
To obviate the friction caused by the boss of the bevil wheels or s or that of the
disc a or a being pressed against the bearings w, when the discs a a¹ or d d' or the
taper drum and the wheels or s, are pressed together as above described, a hoop a²
is loosely mounted on shaft between said wheels and bearings, and in said
hoop a² are mounted to revolve, the anti-friction bowls a³ as shewn by detail drawings
figs. 6 and 7.
Respecting the brake mechanism used in connection with the foregoing arrangement
of parts, a friction pulley e' is formed on the end of the winding drum c, around
which passes the strap the ends of which are manually operated by the shaft c
through the hand wheel e. On the outer end of the shaft c³ are made left and right
hand threads so as to effect a quicker motion of the strap c² as will be well under-
stood. Or the friction pulley c¹ may be mounted on the shaft as shewn by fig. 9.
However, the arrangement shewn by fig. 10 is preferable to that shewn by fig. 9,
since it allows a clutch box or moveable coupling (see fig. 11) to be used at the
end of the drum c, which (said coupling c³) may be thrown out of gear for the
purpose of lowering without all or a great portion of the motor parts being put into
operation.
Since the above described arrangement of parts does not, in any way, interfere with
the parts usually employed for manually operating the cranes to which they are
applied, it will be seen that when they are disengaged, said cranes may still be so
operated.
Again as the arrangements above described are in excess of the gearing and
other parts usually employed in connection with derrick-cranes, the same heing
common and well understood, it will readily be seen that the desired motion for
raising and lowering the "jib " ic by means of the supplementary winding drum c
with the other parts necessary, as well as for raising weights as above described, may
be obtained.
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. A vertical shaft placed centrally in a crane in such a manner that its upper

page_text: or grooved pulley may be mounted thereon, by which, through said vertical shaft,
motion may be imparted to the motor parts of said crane substantially as herein
specified.
2. A vertical driving shaft mounted centrally in a crane, having its upper outer end
projecting beyond the upright and guys of said crane, and being so arranged that all
the moveable parts of the crane may be rotated about it (said vertical driving shaft)
substantially as and for the purposes specified.
3. The vertical driving shaft g, pulley 1, shaft b, the discs a, d, wheels e, f, the
discs a wheel e' and the antifriction bowls a in combination substantially as herein
set forth and as illustrated by the accompanying drawings.
4. The pulley the vertical driving shaft g, shaft b, the bush or drum wheels s
and and the antifriction bowls as in combination substantially as herein
specified.
5. The drum c, brake wheel e¹ attached thereto, the strap c³, shaft c³ having left and
right hand screwed threads made on its outer end, the vertical driving shaft g and the
gearing coupling said shaft g to said drum c in combination substantially as herein
specified.
