I, THOMAS FINNEY of No. 123 Cathcart Road Glasgow in the County of Lanark
Engineer, do hereby declare the nature of this invention to be as follows:-
It relates principally to an automatic or self acting (and self indicating) Dial weighing
machine, which is intended chiefly for use with Cranes and for light or heavy
suspended loads.
It comprises several novelties, both in the character, construction, form, arrangement
and mode (or modes) of operating, its working parts.
It includes the application of certain principles of construction and operation to
crane or suspended weighing machines, such as have not hitherto, to my knowledge,
been applied to such machines.
Although the combined improvements herein-after described are principally
designed for, and applicable to, crane weighing machines for suspended loads,
contemplate applying some of the improvements to other classes of weighing
machines.
The weighing machines which are commonly used for heavy suspended loads, have
not, hitherto, been either self acting or self indicating, but have required the adjust-
ment and re adjustment of the counterpoise weight attached to the steelyard to suit
every successive load: the adjustment being effected by an attendant stationed at the
same elevation as the machine.
Whereas Dial indicating and self-acting suspended weighing machines such as have
been hitherto used were adapted only, so far as I have been able to ascertain, for light
weights not exceeding half a ton, and have had resisting springs to perform the

page_text: functions for which the ordinary counterpoise is designed; my improvements are
intended to render such machines available for weighing heavier loads and with greater
accuracy, in the indications of weight, than hitherto possible by the use of machines
which were actuated by such springs.
I have avoided, in my invention the use of resisting springs to influence the lever
of the first order as I find that springs are uncertain and unreliable when thus used as
agents in weighing machines.
By means of my improvements I am enabled with crane or suspended weighing
machines not only to weigh loads varying from one pound to one hundred Tons, but
to indicate and register such weights automatically upon the dial (or dials) and
dispense with any manipulation of the machine further than the attaching and
detaching of each successive load.
Successive and varying loads may thus, by my invention, be more conveniently,
rapidly and correctly weighed than by the crane weighing machines now in ordinary
use.
By a new character of index (or dial) of a volute form, and a propelling or elongating
finger I am enabled to indicate the weight of very heavy loads upon a comparatively
small dial.
Amongst the novelties contained in this invention there are mechanical appliances
in substitution of the steelyard and its moveable counterpoise, which counterpoise
weight has hitherto been used, and adjusted by an attendant, upon the steelyard of
crane weighing machines for denoting the weight of the load. The said appliances
consist principally of a lever of the first order, of a peculiar form and character, and
an indexed dial and pointer, with members connecting the pointer with the said lever:
the whole combination being intended to denote, automatically, the weight of the load.
This peculiar formed lever is loaded with an immoveable counterpoise weight and is
connected, by chains, or other means, to one or more toothed quadrants: each quadrant
in its turn actuates a ratchet wheel which is immoveably attached to the spindle of the
pointer or finger. These appliances also indicate a new and peculiarly constructed
pointer and index dial. The pointer is automatically and gradually lengthened or
shortened in proportion as the load is increased or decreased; it is thus made to follow
the course of the volute index or dial before referred to.
The following details define more fully the construction and mode of operating the
peculiar formed lever and the propelling finger.
Instead of this lever being composed of one solid bar from end to end it is divided
(vertically) at the load end, after the manner of a "fork," by means of a vertical
slot which extends from the load end, to, a little distance beyond, the load centre,
and thus presents two parallel plates, face to face with each other, at the end just
described.
The load centre passes into, and through, each of these plates, and the fulcrum centre
of this lever is afforded a wider bearing by thus splitting the load end of it, and is
thereby enabled to work with greater steadiness and precision.
The chief peculiarity in the construction of the said lever is the attachment to it
of two, fixed, but adjustable, pendant ears, weights, or metal lappets, in close proximity
to the fulcrum centre but on the outer sides thereof: one ear being attached to one
side of the lever and the other ear to the opposite side.
These (fixed, but) adjustable metal ears, are in the nature of a counterpoise, and,
together with this peculiar formed lever, are in substitution of the moveable counter-
poise weight and steelyard, which are generally supplied with this class of weighing
machine.
The resistance end of this lever is furnished with a band, or chain, which connects
it with a segmental toothed quadrant, pivotted conveniently within the chamber of the
apparatus for actuating the spindle of the dial finger, by means of a toothed wheel (or
ratchet) which is attached to the said spindle.
The operation of this wheel, and its attendant appliances, is as follows: when a
strain is imparted to this lever of the first order, by the attachment of a load, the
resistance end thereof is elevated and a momentum imparted thereby to the band or

page_text: chain attached to the toothed quadrant. As the toothed quadrant responds to this
impulse it is made to turn upon its axis and simultaneously revolves the ratchet wheel
and spindle of the dial finger.
There is a further peculiarity in the form of this lever for the purpose of effecting
a uniformity in the distances travelled by the pointer on the face of the dial, in
relation to corresponding items of weight. My object is to make the pointer travel
over an equal space on the dials' index, when indicating (say) the tenth hundred weight,
to that which it traverses when indicating the first hundred weight.
In order to effect this object I make the resistance end of the lever, in the following
form thus, the outlines of the under side and the resistance end describe a more
acute angle than the outlines of the upper edge of it and the resistance end, which
(latter) outlines describe an obtuse angle; the end itself being slightly segmental in
form.
By means of this particular shaped end (which may be made adjustable or other-
wise) an increased leverage is imparted to the band or chain (which unites it with the
toothed quadrant) in proportion as the load is increased and the lever is elevated
thereby.
The particular niceties of weight, form and adjustment, required to be observed
between the (fixed, but) adjustable counterpoise weight and this particular shaped end
of the lever, being merely details of my invention; which details may vary according
to the size, capacity or use of the machine.
cog
The construction of the Pointer, or propelling finger, and its mode of operation,
may be thus described. The pointer is formed of several parts, some of them being
fixed and others moveable: the principal fixed member being a pointer, of (a more or
less) ordinary form, attached immoveably to a spindle, and, fixed to the back of the
pointer, there are small brackets, placed suitably for supporting another (delicate)
spindle, having on its surface a screw thread or worm. A Bevilled wheel is attached
to the lower end of this (last named) spindle and as the pointer is made to travel
round the dial, in the process of weighing, this bevilled cog wheel (and its screwed
spindle) is made to revolve by contact with a similar and reciprocal cog wheel,
(bevilled to suit the one first nained) which is fixed immoveably to the face of the dial,
or conveniently adjacent thereto, and through the centre of which, (latter) cog wheel,
the pointers' spindle revolves. A moveable Block, Bush, Nut, Barrel or casing is fitted
upon this said screwed spindle and to the said Block is fixed a second (associate) pointer
which is propelled in opposite directions by the screwed spindle, as it revolves, one way
or the other during the process of weighing.
This duplicate, propelling finger is projected more and more beyond the end of the
fixed pointer in proportion as the weight of the load is increased and it is thereby
designed to follow the course of a volute dial.
The "propelling finger" is restrained, and guided, by suitable appliances in addition
to the Block which connects it with the screwed spindle; but these restraining and
guiding appliances are of very minor importance and may be varied in their form and
character and are chiefly for purposes of steadying and easing the travel of the
propelling finger. They may consist of wheels, slots, grooves, eyes astragals, studs,
pins or indeed any agent which will restrain the finger without resisting its necessary
and required movements.
My improved machine comprises also a plan for indelibly recording the weight of
each load, either by printing, pricking or otherwise impressing an indication of it upon
susceptible surfaces placed preferably within one or more of the interior cavities of the
machine. With this object in view I employ the spindle of the pointer, before named,
for the purpose of carrying an additional pointer to serve as an agent in impressing or
recording the weight of each load upon a removeable surface, either paper or other
suitable material.
The dial or surface upon which I thus record the weight, is arranged on the same
(or similar principle as the external and visible dial of the machine, that is, either
volute or circular as required and similarly marked. A lever appliance containing
spring and screw attachments for propelling purposes is used to move back and forward

page_text: alternately as required, either the surface to be impressed or the member which makes
the impression: and this last named lever appliance is preferably wrought by an
attendant and not automatically.
The external form of my improved crane weighing machine is preferably circular
and bears a general resemblance to a watch in the proportions of its casing. Internally
my improved machine contains three or more principal levers, and when thus limited
to three levers two of them are levers of the second order and one of them a lever of
the first order.
The load is attached to, or suspended from, the first lever of the second order and
the weight is transmitted from the said lever to another one of the same order and
from it (or others in succession of the same order) to a final one of the first order: the
weight of the load is thereafter communicated, by linking appliances which connect the
lever of the first order with a toothed quadrant appliance to one or more ratchet wheels
immoveably attached to a spindle which operates a dial finger or pointer placed
externally to the machine.

Agent for the Inventor.

page_text: Lanark North Britain Engineer 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:-
My invention relates to improvements in weighing machines, and instruments or
machines which are operated similarly thereto, and is largely, but not exclusively,
applicable to (crane or other) suspended weighing machines; and the objects of my
improvements are,
1st. to dispense with the use, in weighing machines, of the members called
Steelyards.'
2d. to make the weighing appliances of such machines, self acting without the
agency of springs.
3d. to make weighing machines automatically self indicating.
4th. to furnish weighing machines, internally, with appliances, for recording the
weights of any or every load.
5th. to reduce the dimensions of their indexing members.
6th. to increase the indicating capabilities of their indexes.
7th. to lock or brake the weight indicating members thereof.
8th. to lock the weight recording members thereof.
9th. to furnish weighing machines with members for delivering externally, or
secreting internally, (each either or both) a dated numbered, or other record of every
or any load weighed therewith.
10th. to lock the apparatus so that without the insertion or deposition of a suitable
weight or object therein the machine cannot be put into gear for its several purposes.

Similar letters of reference are used throughout these illustrations to indicate
corresponding parts. I have preferred to shew each part of the mechanism separately,
where possible, in order to make my invention better understood.
Although the combined improvements herein-after described are principally designed
for, and applicable to, crane weighing machines for suspended loads, I contemplate
applying some of the improvements to other machines.
Amongst the novelties contained in this invention, there are mechanical appliances
in substitution of the steelyard and its moveable counterpoise, which counterpoise
weight has hitherto been used, and required to be adjusted, by an attendant, upon the
steelyard of crane weighing machines for denoting the weight of each load. These
said appliances consist, principally, of a lever of the first order, of a peculiar form,
construction, and character, and an indexed dial and pointer with members connecting
the pointer with the said lever; the whole combination being intended to denote
automatically, the weight of the load. This peculiar formed lever is loaded with one
(or more) immoveable counterpoise weights, and is connected, by a chain, chains or
other means, to one or more toothed quadrants, each quadrant in its turn actuates a
toothed wheel which is immoveably attached to the spindle of the pointer or finger.
These appliances also include a new, and peculiarly constructed, pointer and index
dial. The pointer is automatically and gradually lengthened, or shortened, in
proportion as the load is increased or decreased; it is thus made to follow the course
of the volute index or dial before referred to.
The weighing machines, which are commonly used for heavy suspended loads, have
not, hitherto, been either self acting, or self indicating, but have required the adjust-
ment, and re-adjustment, of the counterpoise weight attached to the steelyard, to suit
every successive load the adjustment being effected by an attendant stationed at the
same elevation as the machine.
:
Whereas, Dial indicating, and self acting, suspended weighing machines such as
have been hitherto used, were adopted only, so far as I have been able to ascertain, for
light weights, not exceeding half a ton, & have had resisting springs to perform the
functions for which the ordinary counterpoise is designed, my improvements are
intended to render such machines available for weighing heavier loads, and with
greater accuracy, in the indications of weight, than hitherto possible by the use of the
machines which were actuated by such springs.

page_text: I have avoided, altogether, in my invention, the use of resisting springs to influence
the lever of the first order, as I find that springs are uncertain, and unreliable, when
thus used as agents in weighing machines.
By means of my improvements I am enabled with crane or suspended weighing
machines not only to weigh loads varying from one pound to one hundred tons, but
to indicate and register such weights, automatically, upon the dial, (or dials), and
dispense when required with any manipulation of the machine further than the
attaching, and detaching, of each successive load. Successive and varying loads may
thus, by my invention, be more conveniently, rapidly, and correctly weighed than by
the crane weighing machines now in ordinary use.
By a new character of Dial index, of a volute form, and a propelling, or elongating,
finger, I am enabled to indicate the weight of very heavy loads upon a comparatively
small dial.
The following details define, more fully, the construction and mode of operating,
the peculiar formed lever, and the propelling finger.
Instead of this lever being composed of one solid bar, from end to end, it is,
ordinarily, or may be, divided, (vertically), at the load end, after the manner of a
"fork," by means of a vertical slot which extends from the load end to a little
distance beyond the load centre, and thus presents two parallel plates, face to face
with each other, at the end just described; so that the load centre may pass into,
and through, each of these plates, and the fulcrum centre of this lever is also afforded a
wider bearing than usual and is thereby enabled to work with greater steadiness and
precision.
The chief peculiarity in the construction of the said lever is the attachment to it of
(one or) two, fixed, but adjustable, and preferably pendant, ears, weights, or metal
lappets, in close proximity to the fulcrum centre, but on the outer sides of the lever ;
one ear being, usually, attached to one side of the lever and the other ear to the
opposite side.
These (fixed, but) adjustable metal ears, are in the nature of a counterpoise
weight, and, together with this peculiar formed lever, are in substitution of the
moveable counterpoise weight and steelyard, which are generally supplied with this
class of weighing machine.
The resistance end of this lever is furnished with a band, or chain, which connects
it with a segmental toothed quadrant, pivotted conveniently within the chamber of
the apparatus for the purpose of actuating the spindle of the dial finger, and is, or
may be, made to revolve the latter by means of a toothed wheel which is attached to
the said spindle.
The operation of this wheel, and its attendant appliances, is as follows: when a
strain is imparted to this lever of the first order, by the attachment of a load, the
resistance end thereof is (usually) elevated, and a momentum imparted thereby to
the band, or chain, attached to the toothed quadrant. As the toothed quadrant
responds to this impulse it is made to turn upon its axis and simultaneously revolves
the toothed wheel and spindle of the dial finger.
There is a further peculiarity in the form of this lever, for the purpose of effecting
a uniformity in the distances travelled by the pointer on the face of the dial, in
relation to corresponding items of weight. My object is to make the pointer travel
over an equal space on the index when indicating, (say), the tenth hundred weight, to
that which it traverses when indicating the first hundred weight.
In order to effect this object, I make the form of the resistance end of the lever, thus,
the outlines of the under side and the resistance end describe a more acute angle than
the outlines of the upper edge of it and the resistance end; which, (latter) outlines
describe an obtuse angle: the end itself being slightly segmental in form.
By means of this particular shaped end (which may be made adjustable or other-
wise) an increased leverage is imparted to the band or chain (which unites it with the
toothed quadrant) in proportion as the load is increased and the lever is elevated thereby.
The particular niceties of weight, form, angleing and adjustment, required to be
observed between the (fixed but) adjustable counterpoise weight, weights or lappets,

page_text: and this particular shaped end of the lever, being merely details of my invention,
which details may vary according to the size, capacity or use of the machine.
The construction of the pointer, or propelling finger, and its mode of operation,
may be thus described. The pointer is formed of several parts, some of them being
fixed, and others moveable: the principal fixed member, being a pointer, of (a more
or less) ordinary, form, attached immoveably, (but capable of adjustment), to a spindle ;
and, fixed to the back of the pointer, there are small brackets, or attachments, placed
suitably for supporting a delicate spindle, having on its surface a screw thread or
worm. A Bevilled Cog wheel is attached to the lower end of this, (last named),
spindle and as the pointer is made to travel round the dial, in the process of
weighing, this bevelled cog wheel, and its screwed spindle are made to revolve by
contact with a similar, and reciprocal, cog wheel, (bevilled to suit the one first
named) which is fixed immoveably to the face of the dial, or conveniently adjacent
thereto, and through the centre of which, (latter), cog wheel, the pointer's spindle
revolves. A moveable block, bush, nut, barrel or casing is fitted upon this, said,
screwed spindle and to the said Block is fixed a second, (associate), pointer, which is
propelled to, or from, the pointers axis by the screwed spindle, as it revolves one
way or the other during the process of weighing.
This duplicate, propelling finger, is projected more and more beyond the end of the
fixed pointer, in proportion as the weight of the load is increased, and it is thereby
designed to follow the course of a volute dial.
The "
propelling finger" is restrained, and guided, by suitable appliances, in
addition to the block which connects it with the screwed spindle; but these
restraining, and guiding appliances, are of very minor importance, and may be varied
in their form and character and are chiefly intended for steadying and easing the
travel of the propelling finger. They may consist of wheels, slots, grooves, eyes,
astragals, studs, pins or indeed any agent which will restrain the finger without
resisting its necessary and required movements..
The encased chamber D (Fig. 1), containing two levers, marked E and F, of the
second order, united to a lever of the first order, marked G, which is furnished at the
fulcrum centre with one, or more, pendant ears or counterpoise lappets, G³, and at
the resistance end with a chain, G³, for actuating, a toothed quadrant H, and a
cogged wheel, J, which is fitted upon the pointers' spindle, K, represent the principal,
internal, weighing mechanism of my improved crane weighing machine.
In the encased chamber L, Figs. 7 8 and 14 the pointers spindle K is shewn
fitted with a (disc, or) wheel, M, containing upon its periphery one small notch, N,
which is in a direct line with a pointer, Q, attached (usually) outside the
chamber L, to the spindle K.
In the two adjacent chambers D and L Fig. 8 the spindle, K, is shewn with two
bearings K and K and in Fig. 2 with two bearings K and K.
The notch, N, within the periphery of the wheel, M, is one of the agents which I
employ in a movement for locking together the printing and weighing mechanism
prior to an indelible record of the weight being taken.
The loose, cogged tire, or ring wheel R, is in these illustrations, revolved upon a
fast cylinder, S, and is united with a duplicate "tell-tale" pointer, Q2, which revolves 4
behind the one marked Q, and the corresponding loose cogged tire, or belt wheel, R³,
which is (or may be) revolved upon the opposite end of the cylinder, S (or other con-
venient member) is united to a disc, (or other) wheel and jib, T, which jib supports a
pivotted clutch latchet U, the said latchet being intended for interlocking within the
notch, N, upon the rim of the wheel, M, whenever the latch and notch are in line with!
each other. The bevilled cog wheels, V, and, V, revolve the cogged belts R and R²
by means of the intermediate cogged wheels W and W and their carrying spindle K*
the whole of this movement is arranged for revolving, simultaneously, the duplicate
"tell-tale" pointer, Q³, and the latchet jib, T, and is set in motion by means of the
wheel X (actuated by an attendant) which revolves the spindle K, Fig. 7, and the 5
numerical, recording wheels, Y and Y2, at the same time that it revolves
the pointer Q and the latchet jib T. The numerical wheels Y and Y, or any other

page_text: additional and associate ones, contain, upon their peripheries, provisions for affording
an indelible impression, by printing with ink, embossing, pricking or otherwise
marking it upon a ticket, tape, or ribbon, of cardboard, paper, silk, linen, skin, leather
or other suitable material, whenever the attendant requires to obtain such an indellible
record of the weight, which may be dated or numbered (either or both) automati-
cally and simultaneously with the recording of the weight, if it is required, by adding
certain other wheels to those marked Y, and Y2, for dating and numbering purposes,
or the dating and numbering may be effected by a separate motion from that which
records the weight, the motive power being applied by an attendant to the crutch or
other shaped lever Z which imparts a centripetal motion to the segmental plates, a,
and cause one, or more, of them' to clutch, and draw down into the notch N, the
hanging latchet U, by catching it at its lower end Us with the overhanging flange, a²,
thereby interlocking the weighing wheel, M, and the registering wheel, or jib, T,
with their joint and associated mechanisın. The duplicate pointer Qand the latchet, U,
are so arranged as to be in a direct line, one with the other, so that when the load is
indicated by the pointer, Q, and the handle, X, being then revolved until the dupli-
cate pointer Q is brought round to the same position as that indicated by the
pointer, Q, the latchet, U, and the notch, N, are exactly in line with each other,
and may be interlocked, one with the other, by applying pressure to the printing
lever Z.
The latchet, U, is carefully adjusted to the width of the notch, N, so that until the
two pointers are exactly in line with each other, the latchet cannot be made to enter
the notch, N, or the weight recording surfaces, of whatever kind, be brought into
contact.
For the sake of simplicity I have shewn only one method (in these illustrations) of
bringing into contact the printing or other recording surfaces, thus ;
To the lever Z, fig. 16 I attach one or more link rods, b, loosely pivotted to Z, and a
short lever arm, c, united to the spindle, K', and to a convenient part of the same
spindle I attach one or more (other and additional) levers, d, Figs. 7. 10 and 18 for
the purpose of projecting the ram, e, and the ribbon, f, Figs. 7 and 18, against the
numerical, or other, signs upon the wheels Y, Y' (or any other such like and additional
wheels), the ribbon or tape being contained preferably on a spindle, or reel, supported
by jaws or brackets, g, and I make this reel easily removeable and replaceable by
means of a removeable cap or label, h, which on being taken off enables the spindle to
be withdrawn from the retaining jaws; or any other simple means may be employed
to render the reel replaceable.
Upon the lever, Z, fig. 16, I also provide a short lever movement for operating the
spindle, K, and its associate wheels and pulleys; thus, to the spindle, K³, (bracketted
conveniently to the machine for the purpose) I attach a ratchet wheel, j, and actuate
it with the pawl, k, and to the same spindle, K³, I affix a toothed, or cog, wheel, 1,
Fig. 7 of suitably enlarged proportions for revolving the small cogged wheel, m,
Fig. 7 at a more rapid rate than the wheel, j, Fig. 16 in order that, by a short move-
ment of the lever, Z, I may effect the withdrawal of the printed portion of the ribbon
and present a clean part thereof to receive the next impression. The ribbon is clipped
firmly between the pulleys, n, and, n³, and, withdrawn by them from the printing
appliances on the printing pressure being removed from the lever, Z. The crutch
arm, p, Fig. 9, attached to the bracket, q, is provided with a swivel or small roller, r,
over which I prefer to carry the tape or ribbon as it unwinds from the reel and when
it is required to secrete the ribbon records as they are projected from the pulleys, n,
and n², instead of rendering them accessible to the attendant I provide a gripper or
spindle attached to, and revolved by a coil, or spiral spring, for the purpose of coiling
and storing the printed tape until it is required, preferably, within the chamber L:
For the purpose of locking the weighing mechanism of my crane weighing machine
in order that it may be lowered (when required) for examination and printing, 1
provide a brake movement, within the machine for exerting a secondary brake action
upon the spindle K. This may consist of a disc or wheel, such as M³, or any con-
venient flange, or member associated with any wheel attached to the spindle K, and
B

page_text: any simple kind of ram, arın or lever, the surface of which is, preferably, roughened
to bite the periphery of the wheel M, which is rendered adjustable by means of a
spring, which may be either employed to brake the wheel or to withdraw the brake,
the impulse being imparted, when the machine is suspended at an overhead elevation,
by means of a chain, cord or other such, suitable, member. Such an arrangement is
shewn by, s, fig. 1, for braking or locking the weighing mechanism; the means for
braking such wheels may be greatly varied although the result would be the same.
I have arranged a brake morement also for the duplicate fingers mechanism, which
is similar in character and operation to that above detailed, namely by projecting a
brake, t, fig. 12 to, against, or from the periphery of the disc or wheel I preferably
by means of a spring movement enclosed, conveniently within, or upon, the
pedestal, the brake wheel in this case is attached to the tire wheel R2, and
revolved by the wheel W, but might be placed in any other convenient position and
operated possibly by the wheel W. The brake pressure in either of these case may
be. either centripetal or centrifugal, and imparted by such means, if required, (as in
the case of a machine suspended overhead) as cords, chains, wire &c.
The pointer Q, shewn in Figs. 3. 4. 5. 6 and 11 is furnished with members for
purposes of elongation, in order to adapt it for following the course of a volute index
such as P, figure 3: it is, or may be, constructed thus, (see figures 3 and 4); the
member, q, is fixed firmly to the spindle K, and has a sliding, pointed, shaft or
finger, q³, adjusted to it suitably for being projected, increasingly from, (or to), its
axis, in proportion as the spindle K, is revolved. The bevilled wheel, q², is fixed
immoveably to the machine, and, q, to a revolving spindle 98, which is sustained
between centres q8 attached to q2; it will thus be seen that in proportion as the
spindle, q, is revolved, it projects the shaft, 9%, to, or from, the axis of the pointer Q,
by means of a screw worm, or spiral member acting in concert with a stud, boss, or
other agent, 9', attached to q³. q' is a pully for the guidance of 9. In figure 5 I
shew a method of constructing an elongating pointer with a rack and pinion wheel
movement, operated automatically by the revolving of the spindle K, also a duplicate
pointer combined with the above and arranged suitably for operation by the
spindle K³.
In figure 6, I shew another combination of members-consisting of a tubular
pointer containing within it a duplicate screw pointer, with cog wheel attachments for
revolving an external tube and thereby projecting the screwed pointer to, or from, the
axis of the spindle K, and in figure 11 I shew other means for attaining the same
object, namely, the progressive elongation of the pointer.
In order to insure a uniformity in the indications of weight, given by the
pointer upon the index of my improved weighing machine, I make the resistance
end, G, of the lever G, separable from the body of the lever, and adjustable at an
angle thereto, also of a peculiar form. The resistance end of the lever, G, is
segmental in its configuration, and this arc segment would be, in ordinary circum-
stances, described from the fulcrum bearing, as a centre. but in order to obtain an
increased leverage as the load increases, I have described this arc segment from a
point, located below or above the fulcrum centre as the case requires; and in Figure 1,
I have shewn certain possible means for making this, (nose), and adjustable ;
namely by pivotting the end, G, to G, at G, and fixing it in any required position
by means of any suitable agent such as the screw G. My reason, for varying the
angle of the lever G's resistance end, is to suit a well known action of levers of the
first order when thus weighted which gradually diminish the length of their radial
travel in proportion as the load increases in weight. This fact would necessitate a
variation in the markings of the index (that is, a gradual diminution of the spaces
between the marks, from the commencement of the scale to the end of it, would be
necessary) but for the plan, above described, of making the resistance end of the
lever G, of the peculiar segmental form and adjustable (as described, and shewn in
the drawings, herewith).
I provide a guard upon the pivotted, or adjustable, end, G³, and upon the corre-
sponding member of the toothed quadrant, H, to prevent the possibility of the

page_text: chain, G, or other such connecting agent from getting out of its place when the
machine is moved from place to place.
11.
In order to give greater scope to this method of obtaining equality in the index
markings, I propose, when required, to employ similar means to those just described
in connection with G³ for regulating the segmental surface of the quadrant, H; upon
which the chain, G³, engages. I contemplate, also, interposing transmitting wheels
between the toothed quadrant, H, and the wheel, J, whenever such a course would
prove beneficial.
f
The revolution of the spindle, K, Figs. 7 and 18 and all its associate members,
may be increased by interposing additional wheels for the purpose if necessary."
The rollers, Y & Y₁, Figs. 8 and 10 which bear upon the numerical wheels, Y,
and Y, are for inking purposes.

The spring Vs Fig. 7 is to insure a perfect engagement of the bevilled wheels, V,
and V2.
'
1. :
To prevent, or reduce the oscillation, or vibration, of the lever, G, and the.
pointer, Q, when the machine is in use, I connect one, or more, paddles G. to each
fappet G2 and immerse them in a resisting fluid, preferably oil or Glycerine, enclosed
suitably in a vessel within the lever chaniber D. :

In figure 16 I have shown a method of locking the printing mechanism by a lever
movement which is, or may be, released, or unlocked, by the insertion of a weight or
any other suitable object except a coin, thus ;
..
I lock the disc wheel, u, automatically, by means of a weighted pawl, u³, which can,
(when so required), be released only, by the insertion of a weight or any other
suitable object except a coin, preferably at Z1, which is precipitated (or delivered)
at Z, and exerts a depressing impulse upon the end of the pivotted lever, Z³, sufficient
to dislodge the weighted pawl, us, and enable the disc wheel, u, and its printing
mechanism to be put in operation. The lever Z³ is restored to its original position
behind the pawl, u³, only, as the lever, or arm, 'Z, is raised during the printing motion
and in its elevation the lever arm Z, lifts up the lever Z³ to its nominal position.
The lever is restored to its nominal position by such means as the springs
marked ; the lever Z³, may be united to the division plate L³, by means of a
bracket, u.
I
I prefer to introduce the releasing agent at a position such as that indicated by Zu
and deliver it upon the pivotted (or other) platform Z³, which is suspended in a
sensitive manner to, and from, the end of the lever Z³.

In Fig. 17, I have shewn a view of the segmental wheel, a, (divided, here, into four
segments only) illustrating how each segments' centripetal and centrifugal motion is
effected, namely, by means of the slots, a³, and the pins, at, which, latter, are here
shewn fixed to the division plate L³ so that on pressing down the projecting part of
the lever Z, as here shewn, the motion causes the disc, u, fig. 16, to revolve partially
upon a boss, or centre, such as, u³, and by means of the pins, u³, which project through
the segmental slots, u, in the division plate L³ the motion is communicated to the
oblique slots, as, and the clutch, U2, figures 7, 8 and 12, engages with the flange, a³,
and draws down the latchet U into the slot N.
'
By P, figure 3, I have illustrated my method of increasing the indicating capacity
of a dial index by making the index of a volute form instead of annular or, (as in the
case of many weighing machines), putting it on a long and cumbersome steelyard;
and I am thus enabled to compress iny index for a machine which is required to weigh
very heavy loads into much less space than could be done by any steelyard. I also
effect a saving of space in the indexing members of weighing machines for heavy
loads by the use of an annular dial, only, and a loaded lever, instead of a long and
cumbersome steelyard.

In figure 18 I have shewn an arrangement for storing and delivering tickets for the
reception of an impressed, or printed; record of weight; thus, over the pulleys'Z1
I arrange an endless tape and provide a supply of tickets in any such a way as shewn
at Zsupported by a bracket Z18, underlying the endless tape, and I project them
onward and discharge them; one at a time over the pulley at 21 by an impulse given

page_text: to the pulley near the trough Z by the elevation of the latter said trough into a line
with the sloping shed Z, upon, and along which shed the tickets are delivered into
the trough Z, and thence projected, as required, underneath the numerical wheels Y,
and Y, etcetera by the ribbon projecting movement before described in connection with
the wheels, n and n². I also provide, either separately from or in addition to reel of
tape or ribbon (g, h,) an endless tape arranged over pulleys Z", for propelling
purposes, and operate them by the medium of the wheels n, and n³. I contemplate
the use of a double or multiple tape, or ribbon, supply from (either) the same or
associate reels or spindles, for the purpose of delivering one, or more, ribbons
externally and storing, at the same time, one or more ribbons internally within the
weighing machine.
The numerical wheels are arranged upon a very simple system, commonly adopted
for Register wheels used in dating and numbering appliances, and such actuating
mechanism forms no part of my invention.
The trough Z is elevated or lowered by means of a tape, chain or such like
agent Z24, revolved upon a pulley Z", and is operated by and connected with the lever
motion represented in Figs. 8 and 16 by Z, Z, Z¹³, & Z¹
In figure 8 I have shewn an upright break rod, R³ which is used as a break for
engaging the cogs of such a wheel as W or Ws, as a further or alternate method of
locking the printing mechanism.
The bar R³ is engaged at R*, by the lever Z³, and is raised or lowered, by the
lever Z, acting by the medium of a link rod Z. The rod R', is guided in its travel
by such means as guiding pins working in slots R', figs. 7 and 8.
My improvements are capable of being equally well effected by making variations
in the shape, number and position of certain of the means above described for effecting
them, thus, I may use more than three principal levers in the chamber D; more or
less than two lappets to the lever G; more than one segmental toothed quadrant H or
cogged wheel J; or may vary the position and form of the break wheels M, or M²
and the breaks, s, and, t; I may substitute one or more cross bars in lieu of the
division plate L³ and may vary the positions and increase the members of the clutch
latchet movement; I may effect the automatic elongation of the pointers by slightly
different arrangements of its members; and I may increase the number of the dials,
recording wheels, indexes and associate levers, rams and pulleys for the printing or
other mechanism without in any way departing from the fundamental plan of con-
structing and operating the several appliances. I do not claim, broadly, in weighing
machines, the use of annular indexes or dials or of coin releasing appliances or
numerical wheels, types, or such like agents; or the use of steadying arms immersed
in fluids.
