A Cart or other vehicle for Coal lime bricks or other loose and heavy goods
requiring to be tipped to empty is in accordance with this invention constructed as
follows. The Cart chest or body, which may be of any ordinary construction or
material is hung upon pivots within a frame, of Wrought Iron by preference, of a
rectangular shape, the cross pieces of the said frame being at the front and middle,
and the sides being sufficiently open at the back for the tail of the Cart to drop
sufficiently for tipping. A cranked cross tie may however if preferred be fitted at
the back of side pieces of the said frame dipping sufficiently for the cart chest or
body to tip and forming a stop for same. In this case it is preferred to attach to
the cranked cross tie and cart tail a pinion and rack movement or other equivalent
device for tipping the cart to any desired angle, or adjustable stops attached to
frame may be otherwise used for tipping direct by hand.
The frame on which the Cart Chest or body is immediately carried is super-
imposed upon a similar frame to which is attached the shafts supported by axle
and wheels as usual or the said shafts may be prolonged at the back and form
part of the said lower frame, and the said frame is securely supported or stiffened
by iron ties or bars or otherwise stayed as to form substantial basis for the upper
frame and cart chest or body-The upper frame is connected or geared with the
lower frame by a series of four iron or steel levers situated at or near the sides of

frame, the short ends supporting or lifting the upper frame and thereby the cart
chest or body at its four corners, the fulcrums (knife edged as usual) being attached
to lower frame and the lifting pins similarly shaped, to the upper frame. The long
and inner ends of the four levers or rather each pair or couple are connected by
cross bars or bent continuations of the sides and are constructed to act upon a cross
lever attached to the lower framing. The end of cross lever in this case projects
to the outside of the lower framing, and is connected with an index arm or
Steelyard fixed on suitable support on the lower frame before mentioned and by
which when set in action the weight of the cart body or chest with or without its
contents may be readily and accurately indicated and ascertained. The axle of the
cart may be of iron either cranked or straight so as to be suitable to and form a
portion of the above devices. In preference however to the cross lever above
described the connection between the four side levers and the steelyard may be
made by means of a cross bar or rocking shaft resting or supported by the lower
frame or knife edged pivots carrying under or over the side levers two short arms
with which the pivots on the inner ends of the side levers are in connection and
on one of the outer ends projecting to or beyond the side frame is fixed a longer
lever connected with the steelyard as above. Instead of a Steelyard for indicating
weight, a spring indicator or other form may be used. In all cases the chest or
body of the cart with its frame rests firmly on the lower framing when not in use
´ and is secured by suitable catches or fastenings easily releasable when the cart is
at rest and the weighing devices required to be put into operation.
These devices are easily applicable to carts floats traps and other vehicles that
are not required to tip and the shaft frames of which are carried on springs.

We MARY ESTHER COURT, Coal Dealer and SAMUEL TOMLINSON, Clerk both
of Scholefield Wharf Blews Street Birmingham in the County of Warwick do
hereby declare the nature of the said invention for A NEW OR IMPROVED SELF
ACTING WEIGH CART FOR COALS AND THE LIKE" and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :-
This Invention relates to Carts or other Vehicles for conveying Coals Cattle or
any description of goods and consists in constructing such Carts or other Vehicles
with or applying thereto new or improved devices by which the weight of the
contents of such carts or other vehicles may be readily ascertained or the said carts
or other vehicles filled to any desired weight without passing them over ordinary
weigh bridges, the object of the said invention being to enable buyers or sellers
or users of goods to readily ascertain the weights thereof on such carts or other
vehicles without trouble or expense-A cart or other vehicle for Coals, Lime,
Bricks or other loose and heavy goods requiring to be tipped to empty is in
accordance with this invention constructed as follows The Cart-chest or body
which may be of any ordinary construction or material is hung upon pivots within
a frame of wrought iron by preference of a rectangular shape, the cross pieces of
the said frame being at the front and middle and the sides being sufficiently open
at the back for the tail of the Cart to drop sufficiently for tipping. A cranked
cross tie may however if preferred be fitted at the back of the side pieces of-the
said frame dipping sufficiently for the cart chest or body to tip and forming a stop
for same-In this case it is preferred to attach to the cranked cross tie and cart
tail a pinion and rack movement or other equivalent device for tipping the cart
to any desired angle or adjustable stops attached to frame may be otherwise used
for tipping direct by hand. The frame on which the cart chest or body is
immediately carried is superimposed upon a similar frame to which is attached
the shafts supported by axle and wheels as usual or the said shafts may be
prolonged at the back and form part of the said lower frame and the said frame
is securely supported or stiffened by iron ties or bars or otherwise stayed so as to
form a substantial basis for the upper frame and cart chest or body. The upper
frame is connected or geared with the lower frame by a series of four iron or steel
levers situated at or near the the sides of the frame the short ends supporting or
lifting the upper frame and thereby the cart chest or body at its four corners the
fulcrums (knife edge shape as usual) being attached to the lower frame and the
lifting pins similarly shaped to the upper frame. The long and inner ends of
the four levers or rather each pair or couple are connected by cross bars or bent
continuations of the sides and are constructed to act upon a cross lever attached
to the lower framing. The end of cross lever in this case projects to the outside
of the lower framing and is connected with an index arm or steelyard fixed on

page_text: suitable support on the lower frame before mentioned and by which when set in
motion the weight of the cart body or chest with or without its contents may be
readily and accurately ascertained and indicated. The axle of the cart may be of
iron either cranked or straight so as to be suitable to and form a portion of the
above devices. In preference however to the cross lever above described the
connection between the four side levers and the steelyard may be made by means
of a cross bar or rocking shaft resting or supported by the lower frame on knife
edge pivots carrying under or over the side levers two short arms with which the
pivots on the inner ends of the side levers are in connection and on one of the
outer ends projecting to or beyond the side frame is fixed a longer lever connected
with the steelyard as above. Instead of a steelyard for indicating weight a spring
indicator or other form may be used. In all cases the chest or body of the cart
with its frame rests firmly on the lower framing when not in use and is secured
by suitable catches or fastenings easily releasable when the cart is at rest and the
weighing devices required to be put into operation. These devices are easily
applicable to carts, floats, traps and other vehicles that are not required to tip and
the shaft frames of which are carried on springs.
We now proceed to particularly describe and ascertain the said Invention and
. in what manner the same is to be performed reference being had to the accom-
panying drawings.

Figure 3-Sheet 1-is a half plan shewing framing and machinery.
Figure 4-Sheet 1 is a back elevation of a portion of the cart framing and
machinery.
Figures 5 and 6-Sheet 2 shew the Invention as applied to a two wheel light
spring cart.
Figures 7 and 8-Sheet 2 shew a plan of a modified arrangement of balancing
levers.
Figures 9, 10 and 11-Sheet 2 represent details appertaining to designs on this
sheet of the above.
Figures 12 to 19 inclusive-Sheet 3 shew to an enlarged scale details of various
parts of the machinery of these carts applicable generally.
Similar letters of reference refer to corresponding parts throughout the whole
of the figures.
In Figures 1-2-3 and 4-Sheet 1-A is the cart chest or body which is shewn
as ordinarily constructed of wood with side boards at top. B is the axle tree
C, C, the wheels and D, D, the shafts all of the usual type and construction for
this class of cart.
The parts and combination covered by this Invention will now be described.
E, E is the upper framing shewn as constructed of angle-iron or steel with cross
pieces e, e to the latter of which the cart chest is hinged on the pivots e³, e³.
F F is the lower or main framing with cross pieces f f' also constructed by
preference of wrought iron or steel and of the girder section as shewn.
To ensure the utmost lightness with ample strength these frames are preferred
made of rolled steel and may be either rivetted or bolted together with proper
flanges but rivetting is preferable.
The front ends are prolonged as shewn at f³ for shaft attachments and are
stiffened by the cross tie bolt f. At this part is fixed the usual locking bar G
with handle g working on pivot g2 and engaging with notched ends of the
fangs gå and g₁ by which the cart chest is made fast to the under framing and
easily released for tipping. A special locking device H is also fixed at the back
of the cart to steady the chest when in transit and to relieve the strain upon the
sides of the frame E, E, when weighing as follows:-Two bars of equal length h h
work on pivots h3, h4, and are connected with a pin and slot attachment h³ as

page_text: shewn in part in Figure 3. The pivots are firmly attached to the framing of cart
chest and the bars supported by proper slides and guides also attached thereto.
The handle ho operates the bars and both ends are thrown out or in in the same
direction when required for tipping or otherwise. As will be readily understood
both the front and back locking devices may be coupled and operate together by
a single handle at front or back. For tipping the chest to any required angle
any usual or known mechanical device may be adopted but we prefer a simple
arrangement I of pulley attached to the top of chest with chain i attached to
lower frame at by which the chest is easily tipped till stopped by stops on
the cross bar f7 of lower framing or by any other stops arranged as may be
convenient.
We now proceed to describe the weighing apparatus as combined with this cart.
To the upper framing E, E, firmly affixed by rivetting or otherwise four pendant
brackets marked e the lower ends of which are formed for lifting by means
of the knife edge levers also affixed by bolts rivets or otherwise four brackets
for carrying the fulcrums of the said levers those at front marked f5 and at back fe.
These latter brackets may be securely braced together either by tie bolts as at fi
or by bars formed in one piece with the brackets as shewn in figure 4. K, K, and
L, L, are a pair of double ended levers formed of the general shape shewn in
figure 3 or other equivalent design. The four short ends are made or fitted with
knife edge fulcrums kk2 and 11 and similar centres ³k and 13 for lifting the
pendant brackets first mentioned. The inner ends of the levers are also fitted with
knife edge centres 5 and 15 which are connected by the link M in connection with
the levers n and n² and the rocking shaft N the latter fitted with knife edge centres
or bearings n³ and n' carried by brackets n³ and no attached to axletree and lower
framing. The centres n³ and n' are reversed but the knife edges are in a central
line as shewn at figure 2. The levers n and n² are made or fitted with knife edge
centres n' and, n8 the former engaging with the link M at its centre by means of
the shackle m and the latter with the lifting rod O in connection with a steelyard
or spring balance (but the latter is preferred) as shewn at P figures 1 and 2. When
a steelyard is used it may be mounted upon the standard p and operated by the
lever p² as usual in platform weighing machines or it may be suspended in. a
similar way to the spring balance. By moving the lever p² the steelyard or
balance P and the above mentioned levers and connections under the cart chest are
lifted and the cart chest balanced and the weight shewn on the steelyard or spring
balance.
The parts of the weighing apparatus above described may be made of Iron, Steel
or other metal, cast or wrought and the details are more fully described below.
We now proceed to describe the detail drawings on Sheet 3 with reference to
special devices for preventing jolts and consequent damage to the acting parts of
the machinery when the cart is in motion. Figures 12 and 13 Sheet 3 shew on
an enlarged scale one arrangement we adopt for the main centres. K K are the
forked ends of the levers carrying centres k and l. The fixed and lifting brackets
are shewn respectively by fo and e. To keep the fulcrum centre k firmly in its
place without affecting its correct working we construct the end of the lever and
the framing of the pendant bracket e with the studs kk and connect the same
with the link spring k³. This may be of any elastic material such as rubber
properly toughened and is forced into position by a proper tool when at sufficient
tension to cause the fulcrum centre k to be kept well upon its bearing at all times:
The studs are so arranged that any vibration of the lever does not affect the length
of the spring thus preserving perfect ease of motion on the centres. Figures 14
and 15 show a modified arrangement of the main centres and lever ends. The
centres and are in this case attached to or solid with the brackets and are
embraced by the levers K as shown which is solid and the studs k7ks are attached
to the lever and fulcrum centre k respectively as shewn in the figures. is the
spring. The springs are shown with broken line indicating that any width in
proportion to the other parts may be used. A further device Q.for preventing end

page_text: play of the levers is shown in these figures and is also applicable with some modi-
fication to the arrangement shewn in figures 12 and 13-q is a cup shaped casting
secured by the bolts q³ to the studs q³ to the face of the lever K. These studs
allow of space for the link springs as shewn. Inside the cup are arranged the
disc q with conical front, the buffer 9 of some elastic material and washer 9.
These are pressed by the bolt q7 sufficiently to force the point q' against the flat end
of the stud with pressure enough to prevent any side motion without absolute
rigidity. Of course there is a corresponding device on the other side of the cart
the two balancing each other. Figures 16 and 17 represent an equivalent device
as applied to the rocking shaft N. This we prefer to make of a light forging of
iron or steel of the section shewn. The inner support n³ is prolonged downwards
and formed with a flange n³ through which passes the bolt n¹º. This screws into
a socket at the bottom of the coupling hook n which acts at its top on a knife
edged opening in the bar N corresponding with the line of the centre n³ as shown.
Between the bolt head and the flange n° is an elastic pad or spring and by screwing
up the bolt any pressure can be brought to bear upon the centre n³ to keep it in
place. A corresponding arrangement is made at the other end of rocking shaft
but inverted as the strain is in the opposite direction. A contrivance on the same
principle is applied to the connection of the end of lever n³ with the rod O to
steelyard see figures 18 and 19-Below the eye of the rod o operated by the
centre n is a prolongation o³ with flange as before The centre n8 is prolonged in
a stud shape the upper part of the stud having a V shaped notch o³. Into this a
pointed finger projects its lower edge corresponding with the edge of the centre n³.
This finger forms part of the link of with screwed socket of at bottom. The
spring of and bolt 07 complete the arrangement for keeping the centre n³ on its
bearing steadily yet without an absolutely rigid connection. All other centres
liable to injurious jarring must be treated in the same manner and one or other
of the devices shewn can readily be adopted to any requirement. Steel springs
spiral or otherwise can be applied if preferred as will be obvious to any skilled
mechanic.
When the cart is in motion and the machinery inactive the main weight of the
levers should rest upon a support under the axletree and a spring pad may be
applied at this point. In figures 1 and 2 the iron axle is shewn bent at b to allow
the movement of the levers and in this way a convenient rest is made but many
equivalent arrangements are obvious. A central clip to hold levers steady and
easily disengaged may be added if preferred. The Steelyard too or Balance should
be mounted with steady clips or supports to prevent jarring when in motion and
made to quickly disengaged when required. We further make provision by the
following or equivalent means for preserving the relative and correct positions of
the parts of the apparatus when brought into action when the cart is not level.
Although in most instances practically level positions can be secured for weighing
and this is desirable yet we find that large deviations transversely or longitudinally
can be dealt with without material error in the result. To prevent the backward
or forward motion of the upper frame guard links are fixed to eyes on the upper
and lower frames but so as to allow of perfectly free motion vertically. To keep
the upper frame quite free in its rise and fall when at an angle sideways we use
the devices shown on figure 4 Sheet 1. At any convenient points sufficiently apart
box shaped brackets S Š are bolted to the outside of lower framing. Corresponding
recessed plates 88 are attached to the upper frame within or between these short
arms or rockers 82 83 are placed the inner ends of which bear against the recesses
in the plates s 8 and rise and fall with the frame preserving an equal distance from
the outer framing. The motion is but slight but the ends of the arms should be
knife edged to prevent friction. The outer ends of the arms or rockers act against
loose pads & backed with elastic packing which may be set up by outside bolts &¹
to take off any tendency to shake or rattle.
The application of this Invention to a non tipping cart is shown on Figures 5
and 6 Sheet 2. A A is the chest which may be fitted with side boards raile or

page_text: other upper gear B is the axle wholly of iron or steel CC the wheels D D the
shafts and 62 62 the springs the whole built much as usual. The general arrange-
ments of the weighing apparatus already described is equally applicable in this
case and as the framing can be completed at the back lighter sections may be used.
Several modifications of the arrangement of main levers may be adopted and to
obtain great strength and lightness a tubular construction may be adopted as
shewn in details figures 7 to 11 Sheet 2. A stand p is attached to the side of
lower frame and carries a hand lever p² by which the necessary lifting power can
be applied to the rod O and the machinery and cart lifted and balanced. Instead
of the spring balance any suspension steelyard arrangement may be used.
With reference to the centres and bearings of the apparatus generally they may
be of hardened steel chilled castings or wrought iron case hardened as is usual in
weighing machinery in accordance with the construction and position and made
adjustable where necessary.
This Invention is also applicable with few easily understood modifications to
four wheeled vehicles.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed we declare that what
we claim is:
1. The construction and use of carts or other vehicles with combined lever
weighing apparatus substantially as and for the purposes herein before described
and illustrated in the accompanying drawings Figures 1 to 19 inclusive.
2. The construction and use of lever weighing apparatus in combination with
Carts or other vehicles in which the connection between the main levers and the
weighing rod O is made by the rocking shaft N and arms or levers n and n³
substantially as and for the purposes herein before described.
3. The application of buffers or springs to prevent the jolting of the centres of
such combined lever weighing machines substantially as and for the purposes
herein before described.
