PROVISIONAL SPECIFICATION.
Improvements in Weighing Machines.
We, ALEXANDER WOOD, of 10 Stockwell Street, Glasgow, and THOMAS
DAVIES, of 297 Main Street, Bridgeton, Glasgow, Weighing Machine Makers,
do hereby declare the nature of this invention to be as follows:-
T
This invention relates to weighing machines, which are provided with enclosures,
or pens, and especially to such machines as are adapted for weighing vehicles and
animals alternately.
The object of this invention is to make the gates or the like, forming the
enclosure or pen, capable of being laid back, so as to allow a larger space than
that usually afforded by the size of the platform, for the passage of vehicles, such
as hay-carts etc., on to and across the platform of the machine.
In carrying out our invention, with a machine adapted for weighing vehicles and
animals alternately, such as the machine set forth in the Specification of our prior
Patent No. 5859, dated 25th March 1892, we provide each end of the platform
with a hinged plate, which supports the pillars at the ends of the pen. The plates
are hinged to the platform in such manner that the gates, when folded up, can be
laid back, so as to increase the space for the passage of a broad vehicle, such as a
hay-cart etc. To counter-balance the weight of the gates, and to enable them to bc
moved from the vertical to the inclined positions, and vice versa, the plates have
attached to them suitable counter-balancing devices, such as levers and weights, or
equivalent mechanism.
When levers and weights are used as counter-balancing devices, stops or catches
are or may be provided for limiting the movement of the levers.
We prefer to hinge the plates to the platform by means of jaws cast on the
bottom of the plates, between or into which pins, projecting from lugs or brackets
on the underside of the platform, enter. The plates turn on the pins in the same
manner as an ordinary hinge.
To prevent the gates accidentally falling over to the inclined position, suitable
pawls or other catches, or stops, are provided. The catches or stops may be
released, so as to permit the gates being laid back by the pressure of the foot, or
by means of a hand lever, or equivalent.
Our invention, though specially designed for use with machines of the class set
forth in our prior Patent aforesaid, can be used with other classes of machines,
where suitable.

COMPLETE SPECIFICATION.
Improvements in Weighing Machines.
We, ALEXANDER WOOD of 10 Stockwell Street, Glasgow and THOMAS
DAVIES of 297 Main Street Bridgeton, Glasgow, Weighing Machine Makers
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 :-
This invention relates to weighing machines, which are provided with enclosures

page_text: or pens and especially to such machines as are adapted for weighing vehicles and
animals alternately.
The object of this invention is to make the gates or the like, forming the enclosure
or pen, capable of being laid back, so as to allow a larger space than that usually
afforded by the size of the platform for the passage of vehicles such as hay-carts etc.,
on to and across the platform of the machine.
In carrying out our invention, with a machine adapted for weighing vehicles and
animals alternately, such as the machine set forth in the Specification of our prior
Patent No. 5859 dated 25th March 1892, we provide each end of the platform with
a hinged plate, which supports the pillars at the ends of the pen. The plates are
hinged to the platform in such manner that the gates, when folded up, can be laid
back so as to increase the space for the passage of a broad vehicle, such as a hay-
cart, etc. To counter-balance the weight of the gates and to enable them to be
moved from the vertical to the inclined position and vice versa, the plates have
attached to them suitable counter-balancing devices such as levers and weights or
equivalent mechanism.
When levers and weights are used as counter-balancing devices, stops or catches
are, or may be, provided for limiting the movement of the levers.
We prefer to hinge the plates to the platform by means of jaws cast on the
bottom of the plates between or into which, pins, projecting from lugs or brackets
on the underside of the platform, enter. The plates turn on the pins in the same
manner as an ordinary hinge.
To prevent the gates accidentally falling over to the inclined position suitable
pawls, or other catches, or stops are provided. The catches or stops may be
released so as to permit the gates being laid back by the pressure of the foot, or by
means of a hand lever or equivalent.
Our invention, though specially designed for use with machines of the class set
forth in our prior Patent aforesaid, can be used with other classes of machines where
suitable.
And in order that our said invention may be properly understood we have here-
unto appended an explanatory sheet of drawings, whereon :—
Fig. 1 is a side view of a weighing machine constructed in accordance with our
said invention No. 5859 of 1892 and having our present improvements applied
thereto.
Fig. 2, is a plan.
Fig. 3, shows the gates at one end folded up and laid back to the inclined
position.
Fig. 4. is an end view of one of the hinged plates.
Fig. 5. is a detail view.
Referring to the drawing whereon the same reference letters wherever repeated
indicate the same parts.
a, a are the pillars of the machine which are fitted in sockets on the hinged plates b,
one of which is fitted at each end of the platform c. The lugs or brackets d are cast on
or secured to the underside of the platform, two at each end. Two jaws fare cast
on or secured to the underside of each plate b and these jaws rest or bear, as shown,
on pins e fitted in and projecting at each side from the brackets d.
A central projection g is cast on or secured to the underside of each plate and
fitted in or secured to these projections are the ends of two levers having adjustable
or fixed counter balance weights i on them.
The ends of the levers may be secured to the projections g in the manner shown
at Fig. 5.
With this arrangement when it is desired to permit a broad vehicle to pass on to
or over the platform of the machine the gates at each end are folded up in the manner
shown at Fig. 3 and are then tilted backwards to the inclined position.
When the gates are moved the jaws on the plates 6 turn easily on the pins e.
The invention may be modified to suit different constructions of weighing
machines.

page_text: We do not confine ourselves to the precise form of hinge or support shown as
other equivalent or analogous forms of hinge can be used.
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 consider novel and desire to claim is:-
1st. In weighing machines the combination with the platform of movable plates
or parts, for carrying the ends of the pen or enclosure, which are so hinged or
supported that the said ends can be readily laid back, substantially as and for the
purpose set forth.
2nd. The combination with the hinged end plates of the counter balance levers,
substantially as hereinbefore described and shown on the drawings annexed.
