centre below its upper end the centre being attached to any permanent object or part
of the machine itself and the lower portion is provided with a nearly horizontal or
other slot or link or projections the upper projection hanging or projecting over the
furthest. This lever is suspended near to the rod upon which the weights are hung
and is kept in an inclined position by means of a supplimental weight-which forms
part of the total weight when weighing-by a cord line or fine chain which passes
upwards and around friction pulleys in such a manner being attached to the top
end of the lever as to pull the lever out of the perpendicular. Now to the weight
rod or other moving part is attached a projection or friction roller which moves
upwards with the weights immediately the scales commence to move by the
impetus of the matter falling upon the scales and this friction roller comes in con-
tact with the top projection upon the bottom of the said pendant lever and by this
time the supplimental weight is releived by the accent of the main weight which
takes the tension from the cord or chain aforesaid and allows the lever to gravitate
to a perpendicular position until it has passed over the friction roller or stop during
which time the scales do not further move but immediately the roller or stop is
liberated on the other side the weighing is completed when the supply is automati-
cally cut off and the door at the bottom released when the stop passes under the
said projections or planes back to its original position for another weighing.
The bottom part of the pendulous lever may have a projecting screw rod with an
adjusting weight to bring the lever over. The under projection is bevelled at the
further end to assist the roller to pass down from the upper to the lower side as the
weighing is completed.

page_text: I, WILLIAM BEILBY AVERY of Digbeth Birmingham in the County of Warwick
Scale Manufacturer do hereby declare the nature of the said invention and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
I'
My invention has for its object improvements in weighing machines and has
reference in particular to that class of machines which are used in connection with
.shoots for weighing corn or other matter capable of similar use and where rapidity
of weighing is a consideration but the invention is applicable to any weighing
machine for the purpose of counteracting the effect produced by such corn, grain or
other matter falling from a distance into the box, hopper or other repository for
receiving and weighing the same. The effect of the fall of any such matter is to
turn the scales too early on account of the impetus produced by the said fall.
:
My new compensating action is as follows:-At one end of the scales but prefer-
ably at the end where the weights are hung a special pendulous lever upon a
centre below its upper end the centre being attached to any permanent object or
part of the machine itself and the lower portion is provided with a nearly horizontal
or other slot or link or projections the upper projection hanging or projecting over
the lowest. This lever is suspended near to the rod upon which the weights are
hung and is kept in an inclined position by means of a supplemental weight-
which forms part of the total weight when weighing-by a cord line or fine chain
which passes upwards and around friction pulleys in such a manner being attached
to the top end of the lever as to pull the lever out of the perpendicular. Now
to the weight rod or other moving part is attached a projection or friction roller
which moves upwards with the weights immediately the scales commence to move
by the impetus of the matter falling upon the scales and this friction roller comes
in contact with the top projection upon the bottom of the said pendant lever and by
this time the supplemental weight is relieved by the ascent of the main weight
which takes the tension from the cord or chain aforesaid and allows the lever to
gravitate to a perpendicular position until it has passed over the friction roller or
stop during which time the scales do not further move but immediately the roller
or stop is liberated on the other side the weighing is completed and the door at the
bottom released. The stop then passes under the said projections or planes back to
its original position for another weighing. The bottom part of the pendulous lever
may have a projecting screw rod with an adjusting weight to bring the lever over
The under projection is bevelled at the further end to assist the roller to pass down
from the upper to the lower side as the weighing is completed.
In order that the invention may be clearly understood and more easily carried
into practice I have appended hereunto two sheets of drawings upon which I have
illustrated a double bag weighing machine with my compensating device attached
thereto.
Figure 1 is a part sectional and part side elevation of the machine with the
compensation attached.
Figure 2.is a plan of the same machine on line A. B.

page_text: Figure 18 & Bide elevation of the compensating gear to a larger scale when the
scales are commencing to weigh.
Figure 6 is a front view of the parts shown by Figure 5.
Figure 7 is a side elevation of the same parts shown by Figure 5 when the
weighing is completed and the scales are just turning back again for another
weighing.
Figure 8 is a side view of the supplemental weight X showing the slot c³ in the
rod C the reason for which will be hereafter explained.
Figure 9 is a diagram view of the lower part of the pendant lever D and stud F¹
showing the pathway of the said stud upon the face of the said lever and which
will assist to make the action clear.
The machine here illustrated is fixed between the upper floor 2 and the lower
floor 1 the working parts being supported by the hanging frames 3 and 4 while the
bags 5 and 6 stand upon the floor 1.
The first six figures are all shown with beam G in a horizontal position the
weight of the corn in the hopper 8 having counterbalanced the weight W at the
other end of the beam and the door 91 having fallen so as to allow only a small
stream of corn or other matter to pour into the hopper 8 which is divided into two
divisions with its two delivery shoots 8' and 82. The supply shoot 7 is opened and
closed by a door 91 attached to the lever 9 and operated by the weight 9' and
allowed to fall by the rising of the weight W with the rod attached thus relieving
the pressure of the roller at the upper end of the rod on the lever 9. It will now be
necessary in following out the weighing to refer to my compensating device of the
lever D as it is the important part and it will be noticed that the supplimental or
small weight X is not resting upon the hook c* so that its weight is sustained by
the lever D through the chain but the jaw F which carries the weight W is
suspended to one end of the weighing beam G. Now the lever D is hung at d¹ to
a permanent part H of the frame work 3 and 4 and is brought into the diagonal
position shown by the small weight X which acts upon the upper end do through
the chain which is run around the fixed friction pulleys and the chain
being fixed to the lever by the adjustable pin, and it always keeps the lever D
in a diagonal position until the hook c¹ which is fast to the jaw or hanger F rises
sufficiently to relieve the weight X and to allow the chain x to slacken when the
lever D is free to fall by its own gravity to the position as shown by Figure 7 its
travel being regulated by the adjustable weight D¹ the chain being also adjustable
by the pin. Now one side of the jaw or hanger F carries a friction roller or other
projection F which has by this time ascended until it rests under the top guide or
projection D at say 11, Figure 9 and it therefore cannot rise further until the
pendulous lever D has passed into its vertical or other position as shown by Figure 7
when the stud F1 rises at the other end of D2 to 12 see diagram Figure 9 which is
the completion of the weighing by the united weights W and X and their accom-
panying parts. At this point the discharge door 83 is thrown open and the contents
of the left side of the hopper 8 is shot into bag 5 while the operation of filling the
right side goes on in the same way by the action of the beam K with its catch k¹
upon the hook m¹ of the lever M. The elevated position of the corn or other matter
being the motive power to support the automatic action of the various parts which
will be thus easily understood. The stop N prevents the beam G from decending.
It will thus be understood that when the weight W brings the beam G upon the
stop N that the hook or projection c³ is carried down the slot c and the weight X
is liberated to bring the lever D into its diagonal position and the door 9¹ being
opened the full effect of the corn in the shoot 7 is upon the hopper 8 and the door 91
falls to admit a small stream only just at the time the stop F is being held by the
upper lip D the lower lip D³ which prevents any serious vibration and also assists
to mark out the pathway of the stud F1 which passes downwards when the
weighing is completed just touching the rounded end d' of the under lip D³ as
shown by Figure 7 when the lever pendulates back over the stud as shown by the
pathway 18 in conjunction with the arrow heads.

page_text: It will of course be quite evident that the lever D may be a reeling lever
instead of a pendant one and the balance weight and arrangement of the chain
friction pulleys may be greatly varied as well as the whole design of the machine
as the compensation arrangement herein shown or any obvious equivalent may be
fixed to any stationary portion of a weighing machine with a similar effect.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
';
The improvements in weighing machines of a steadying or compensating arrange-
ment by which the weighing parts are held and steadied while the substance to be
weighed falls upon the machine substantially as herein set forth.
