A New or Improved Weighing Machine and Automatic Weight
Registering Apparatus.
We DAVID JOHN MORGAN of Walmer House Romilly Road Canton Cardiff in
the County of Glamorgan Engineer and WILLIAM GUY NIXON of 33 Hughendon
Road Stratford in the County of Essex Engineer and WILLIAM GILLIES of
Ardenville Pembroke Road Southville Bristol in the County of Gloucester
Engineer do hereby declare the nature of this invention to be as follows :—
Our present invention relates to an improved weighing machine and automatic
weight registering apparatus the object being to so arrange an apparatus that the
amount of each load weighed is registered immediately upon its removal from the
machine that is to say the amount or weight of each load weighed is indicated and
registered and the total amount of each load as well as the total amount of a
series of loads are also registered. In carrying out the said object we arrange our
improved machine with a back disc or frame which projects forwards and in the
centre of which we secure a spindle upon which works a loose bush or hollow
spindle or sleeve having secured at its end a pointer or finger.
A front disc or frame is secured at the front part of the apparatus and held in
fixed position by suitable bolts or stays fitted to the back disc or preferably by
means of being secured to the solid spindle. The said front disc is marked with
graduations indicative of weight and the pointer or finger aforesaid points to the
same. Immediately at the back of the front disc or frame we arrange a second disc
or wheel which fits loosely upon the hollow spindle or sleeve and has formed at its
outer edge or periphery ratchet teeth which are operated upon by a suitable pawl in
the manner and for the purpose. hereinafter described. The face part of the said
second disc or wheel may also be marked with graduations indicative of weights
and an opening is formed through the front frame in order that said marks may be
observed.
A vertical bar hereinafter called the compresser is arranged to fit or press upon
a horizontal plate which is guided upon a number of vertical rods or pins which
are secured in the projecting parts of the back disc or frame and each said rod or
pin has a spiral spring fitted to it which comes into compression immediately upon
the load being applied to the apparatus. To the underpart of the horizontal plate
we fix a vertical rack which gears with a pinion fixed to the loose sleeve or hollow
spindle. The pointer and inner or second disc or wheel go round together upon' a
load being applied to the machine and when the said load is removed the inner or
second disc or wheel remains stationary thereby registering the amount weighed
while the finger or pointer returns to its original position. The second disc or wheel
is moved round by means of the pawl which is carried upon an arm the boss of
which is keyed or otherwise secured to the loose sleeve or hollow spindle. The
said pawl is pivotted at the upper end of arm and is coupled by means of a rod
to a vertical bar working in suitable supports attached to the arm and a spring is
arranged so as to depress said vertical bar and draw out of gear the pawl unless
otherwise kept in gear by a suitable clutch box which operates upon an arm
arranged to lift the vertical bar. The said clutch box works loosely on the sleeve
or hollow spindle and is moved backwards and forwards by means of a crank-rod
aud lever or equivalent mechanism. In connection with the movement of inner or
second disc or wheel we arrange suitable gearing which operates separate pointers

page_text: upon suitable dials marked with tons cwts. qrs. and lbs. or other representative
weights and in some cases we employ drums or cylinders upon which we place paper
or other material and mark the several distinct separate and collective weights as
desired and the-mechanism for. performing the same is similar to an ordinary steam
engine indicator excepting type or other means of marking the amount weighed are
employed in the place of the pencil in the steam engine indicator and the same is
brought into position ready to mark the paper immediately upon the removal of the
load from the apparatus.
Our improved machine works as follows: The vertical bar which projects above
the apparatus will when the machine is carried upon a chain from a derrick or other
lifting appliance come in contact with a suitable stop by so doing the same presses
on the horizontal bar which depresses the springs and simultaneously the vertical
rack travels downwards thus turning round the pinion and moving the finger to a
point indicative of the amount of load and with the movement of the finger as
aforesaid the inner or second disc or wheel is moved by the pawl and when the load
is removed the pointer returns but the second disc or wheel remains stationary and
registers the amount of the load weighed and this movement of the second disc or
wheel operates means for registering either by pointers or marks either the total or
separate or both amounts of the loads weighed.
We would have it understood that the principal feature in our invention is the
indication and registration of the load weighed subsequent to its removal from the
machine and although we have herein described certain mechanism for performing
this we would have it understood that the same may be modified and equivalent
mechanism substituted for attaining the same object without departing from the
essential parts of our invention.

COMPLETE SPECIFICATION.
A New or Improved Weighing Machine and Automatic Weight
Registering Apparatus..
We DAVID JOHN MORGAN, of Walmer House, Romilly Road, Canton,
Cardiff, in the County of Glamorgan, Engineer, and WILLIAM GUY NIXON, of
33, Hughenden Road, Stratford, in the County of Essex, Engineer, and WILLIAM
GILLIES, of Adenville, Pembroke Road, Southville, Bristol, in the County of
Gloucester, Engineer, do hereby declare the nature of our said invention and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
Our present invention relates to an improved weighing machine, and automatic
weight registering apparatus, its object being to arrange an apparatus to register
the weight of each load weighed immediately upon its removal from the weighing
machine, as well as to indicate the weight of load while on the machine, and
indicate the total amount of each separate load weighed as well as to indicate and
register the total amount of a series of loads: To attain which we arrange a
machine or apparatus as set forth in the accompanying sheets of drawings which
are to be taken as part of this Specification and read therewith.

front view of the mechanism we employ for driving said indicators..
Fig. 8 is an elevation showing our machine suspended to derrick or crane.
Similar letters of reference denote corresponding parts in each view.
Our improved machine and apparatus is arranged with a back disc or frame D
having projections d' made with or secured thereto. In the centre of the disc D
we secure a spindle E, which carries a bush or hollow spindle or sleeve G, at the
front end of which is secured a suitable pointer H. A suitable front disc or
frame J is secured at front part of machine, and preferably held in fixed position
by bolts or stays K. The front disc J is marked with graduations indicative
of weight, and the pointer or finger H aforesaid points towards the same
shown.
as
Immediately at the back of the front disc or frame J we arrange a second disc
or wheel L, which fits loosely upon the hollow spindle or sleeve (and has formed
at its outer periphery ratchet teeth g' (see Figs. 2 and 4) which are operated upon
by a suitable pawl 2 in the manner and for the purpose hereinafter described.
The face part of the said second disc or wheel L is also marked with graduations
indicative of weights, and an opening is formed through the front disc or
frame Jin order that said marks may be observed. A vertical bar M hereinafter
called the compresser is made with or secured to a horizontal plate O, the latter
being guided by a number of vertical rods or pins P- which are secured in the
projecting parts d¹ of the frame D, and each said rod or pin P receives a suitable
spiral spring g, which becomes compressed immediately upon the compresser M,
coming in contact with the stop piece see Fig. 8. To the underside of the
horizontal plate O we secure a vertical rack N, with which gears a pinion Q,
which is fixed to the hollow spindle or loose sleeve G. The wheel or disc L has
its centre part 2 preferably made in the form of a ratchet, and a pawl 1 is
mounted upon the inner face of the front disc J which gears therewith, and so
prevents the wheel L moving back after it has been carried round any distance
by the pawl g². The said pawl 92 is mounted upon a lever or arm R, the boss l
of which is keyed or otherwise secured to the loose sleeve or hollow spindle G.
This pawl is pivotted at the upper end of said arm R and is coupled by means
of a rod to a vertical bar 3 working in suitable guides, attached to said
arm R, and a spring is arranged so as to depress the bar, and put out of
gear the pawl g, excepting when otherwise kept in gear by a clutch box S,
which is operated upon by a lever s', horizontal rod 2, and hand lever s³, and.
the said clutch box S has a flanges which bears against the underside of a
projection fixed to the lower end of the bar r³.
Referring to the registering mechanism shown in detail at Figs. 5, 6 and 7. . The
wheel or second disc L has a single internally projecting tooth which operates at
every revolution of said wheel or disc L a register wheel Y which obviously moves
one tooth at every revolution of the disc L. The said wheel Y having ten teeth
its revolution will indicate ten revolutions of the disc L. The wheel gears with
an intermediate wheel W which has ten ordinary teeth to gear with the wheel Y
and one extending tooth w' which extends on one side see Fig. 6 so as to keep
clear of the wheel Y and operates the projecting teeth cl of the index wheel V, it
will therefore be obvious that it takes ten revolutions of the wheel Y to make one
revolution of the wheel V. The said wheel V gears also with an intermediate
wheel Z which has ten ordinary teeth to gear with the ordinary teeth of the wheel V
and an extending tooth 2' which extends on one side so as to keep clear of the
wheel Y see Fig. 6, and operates an index wheel Q' which has ten ordinary teeth
as shown so that it takes ten revolutions of the index wheel V to make one
revolution of the wheel Q. The intermediate wheels W and Z are mounted upon
pins w² and ² which are screwed to the front plate J and the index wheels Y, V,

page_text: and Q are mounted upon spindles y³, and q2 which are carried in the plate J and
extend through the same and receive suitable fingers f which point to marks
indicated within circles marked on 'said disc at f² see Figs. 1 and 5. It will be
obvious that where desired each register wheel, or its spindle could carry a drum,
around which could be placed a paper cylinder, and type or other means of
impressing or marking on the paper the amount or weight to be registered could be
arranged to come in contact with each said paper cylinder immediately the load
was taken from the apparatus. We do not illustrate this but merely describe it as
an obvious addition to our apparatus and not an invention which we desire to claim
per se.
Our improved machine and apparatus works as follows:
The load is hung on to the apparatus at m², and the machine when carried by the
derrick X, is arranged so that the depresser M comes in contact with a stop 1, see
Fig. 6, which is fixed to chain 2, by this means the plate O descends and com-
presses the springs q, which are arranged in strength to suit loads to be weighed,
and at the same time the vertical rack N moves round the pinion Q, and the sleeve
or hollow shaft G which moves with it the arm R, the pawl y² of which moves
round the wheel L. The finger H also moves round with the hollow spindle G
and points to one of the marks, indicative of the weight of load, and the face
part being marked with a corresponding weight visible at 2. Upon the load
being removed from the machine the springs q lift up the bar O, and depresser M,
and the rack N turns the pinion g so as to bring back the arm R and finger H to
original position, leaving the wheel L still showing the amount of load weighed,
and consequently registering the same. As soon as the wheel L has so made one
revolution, the tooth moves the wheel Z one tooth, and as soon as the wheel Z
has made one revolution, the tooth y₁ of the intermediate wheel Y, moves the
register wheel W one tooth, and this wheel upon its revolution causes the tooth v
of the intermediate wheel V, to move the register wheel T one tooth.
It will be now clear that the amounts of each load is indicated by the pointer H
and each load registered by the 'wheel L, and the total amount of a series of loads
weighed registered by the register wheels Z, W and T with the pointers f¹..
We do not confine ourselves to any particular indications marked at j¹, or on
face of wheel L, or on the dials f, neither do we limit ourselves to the exact
mechanism shown at Fig. 5 for registering the total amount of loads weighed, as it
will be obvious the gearing may be modified to suit the particular loads required to
be weighed. We would also have understood that our improved registering
apparatus as combined and arranged could be applied to other forms of weighing
machines than that shown.
Having now particularly described, and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :
ab

depressable plate O, rods P, springs q, rack N, with a pinion Q, arranged to
