-Improvements in Automatic Weighing Machines.
We, EDWARD HENRY BECKETT, of Glen-eu-lan, Tan-y-grisiau, in the County
of Merioneth, North Wales, and CHARLES WARREN ROBERTS, of Plas Wennydd,
Blaenau Festiniog, in the County of Merioneth North Wales, Engineers, do hereby
declare the nature of this invention to be as follows :-
First, certain details in the construction or arrangement of the dial indicating
mechanism, and secondly, certain details in the construction or arrangement of
mechanism whereby the weight of persons or articles, on the platform, is auto-
matically registered and permanently recorded.
To carry our invention into practice, and as we show in the annexed drawings of
which
.
Figure 1, Sheet 1, is a front elevation, showing. the indicating mechanism in its
normal position, and,
Figure 2, Sheet 2, is a back elevation showing the release action. This is also
in its normal position and corresponds with the front elevation, Figure 1.
The invention consists of a central rod A. which is provided at its upper end
with a toothed rack B. which gears into a toothed wheel C. The wheel C. is fixed
to a spindle which carries the dial pointer at its outer end. ·
The lower end of the rod A. runs free into or over the rod D. and is fitted with
an adjustable stop Z. This rod D'being connected to the levers of the platform
in the usual way.
The rod A. is free to fall by its own weight and is guided by the guide
rollers E.
When A is in its normál position, it is retained by the catch F which slips
under the noggle or lug G, this noggle or lug being fixed on the back of the
rod A...
The catch F. is fixed on the spindle H. and is held up to its work by the lever J.
and the counterpoise K.
The spring finger L. is secured at one end to the roď Ą. and the other or outer
end is provided with a pencil.
The reels or drums M. and N. are set and revolve on the vertical spindles O. & O.
A coil of paper or metallic tape is wound on the reel or drum M. and the loose
end made fast on the reel or drum N. so that the said tape may be wound from the
one on to the other.
The lovers P. and Q. are fixed to a spindle R and form a bell crank.
'
The out end of the lever Q is forked and rests on the pin S fixed in the rod A.
The top end of the lever P. is connected to the rod T. The end of the rod T.
is fitted with a moveable finger U. which gears into a ratchet wheel V. fixed on
the reel N.
W. is a counter connected to the top of the rod A. by means of the connecting
rod X and registered a unit for each descent of the rod A.
Y. is the weigh spring, and receives the weight from the platform through the
rod D.
The action of the machine is as follows.
I
A certain body or weight to be accertained, is placed on the platform in the
ordinary way. The said weight being transferred to the spring Y. through the
ordinary platform levers, and the rod D.
The spring Y is compressed a certain distance the rod A. being retained in its
normal position by the catch F.

page_text: The catch F. is now removed by turning the spindle H. slightly in one direction.
This may be done by a handle on the end of the spindle, or, by an arrangement of
levers as shown in Figure 2, which are actuated by a falling body, such as a
check, or tally, falling on the ends of the levora A, A', which by ineans of the
connecting rods B' and B' to the double ended lever C gives a rotary motion to
the spindle H.
The catch F. being removed, the rod A. falls until the stop Z. roste on the end
of the rod D. and thus moves a distance equal to the compression of the spring Y.
The motion of the rod A. is communicated to the dial pointer through the
rack B, and the wheel C. and the weight is shown on the scalo on the dial.
The finger L. with pencil attached has also traversed the distance of the com-
pression of the spring Y, and in its descent has marked a line on the tape stretched
between the drums M. and N. This line, if read with a suitable scale will give
the recorded weight of the article on the platform.
Now, remove the weight from the platform and the spring Y. will return to its
normal position and carry with it the rod A.
The rod A. by means of the rack B. and the wheel C. returns the dial pointer
to zero. Also, by means of the connecting rod X it moves the counter W and
registers one unit.
Also, the pin S. raises the lever.Q and imparts motion through the lever P and
rod T, to the ratchet wheel V. and turns the reel or drum N. thus winding the
tapo on to N. and off M. and places a fresh colimu under the pencil on the
finger L. ready for the next load to be placed on the machine.

Improvements in Automatio Weighing Machines.
We EDWARD HENRY BECKETT of Glan-eu-lan, Tan-y-grisiau, North Wales
and Charles WARREN ROBERTS of Plas Weunydd, Blaenau-Festiniog North
Wales, Civil Engineers, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement :-
This invention has for object the construction of a weighing machine in or by
which the weighing of the articles is shown on a dial, a record of the number of
weighings made and the respective weights in addition to a checking system by
which the person weighing the goods or articles can be identified supposing
several persons had access or be told off to do the weighing, there being no
indication of weight or movement of the indicating mechanism until an appliance
such as a token or tally of special kind be put into the machine to serve for
moving a balance and freeing itself the movement of the balance disengaging a
locking device before the weighing and recording can take place. The recording
is by marking paper which moves a stage at each weighing.
As an example of the utility of our invention, supposing six persons in a wharf
or factory bad the power to weigh and receive or weigh and deliver goods, we
provido each of the six persons with metal tickets specially marked or numbered
by which they would be known. Now say No. 3 conducts a weighing, he, after
placing the goods upon the machine platform, inserts n No. 3 ticket, this by
dropping on certain levers releases the locking device and the weighing, the
recording and the numbering appliances are set free to act accordingly. The
same operations are brought about after any other ticket is inserted and so on.
The order of the tickets found in the machine correspond to the recording chart,
thus a complete and perfect system of checking is established, the only duty

page_text: reat.
The invention will be clearly understood by reference to the annexed drawings.
in which
Figure 1 is a front sectional elevation.
Figure 2, a side sectional elevation.
Figure 3, a sectional elevation from the back of the upper frame, and
Figure 4, a plan on the line a, a, of Figure 3.
As represented on the drawings the machine is supposed of the usual platform
kind, with a rod A and spring B for compression by the weight of the goods the
upper mechanism remaining fixed until the token or tally has been put into the
frame and upon a rod V, or tube, or receiver chamber, to press down levers W, W,
and cause release of stop or catch X from block Ÿ to free the indicating and
recording mechanism.
The metal token or tally, having a central hole, when placed over the rod V
after opening the flap V' slides down said rod and its weight on the levers W, W,
overbalances them and then slides clear but remains upon the rod for aftor
collection and checking.
The upper end of the rod A is surmounted by a screw thimble for the
adjustment of the nut e for putting compression on the spring B and thereby
balancing the normal weight of the platform on its beam. The upper end of the
rod A is hollow for the lower end of a second rod C to move in to the distance of
the springs compression, due to the weight put on the platform, the nut d on the
rod C acting as a cushion to prevent concussion and to limit the descent of the
rod C in accordance with the length of the rack D and the desired travel of
the finger F.
The rod C has at its upper part a rack D and is guided for vertical motion by
the rollers E, E, the rack D being used for operating the finger F by the pinion ✪
to indicate the weight in the well known manner. The rack D by its arms I
and link causes the counter K to register the number of weighings in succession,
said index mechanism being enclosed in a casing but visible through a glass.
The rod C carries a pointer L with a pencil or marker projecting therefrom to
descend with the rod C and bear against and mark the surface of paper M secured
to two reels. N. N' from one of which the paper can be drawn and taken up by
the other at each uprising motion of the rod Ċ by the stud pin P pressing up the
arm which otherwise rests on it.
The stop Q prevents the arm Q descending more than is required for the
paul S to engage in the next tooth in order that the pencil in returning may go
back over a great part of the same mark it made in its descent.
The arm is pivoted at R to operate the paul S for pushing the reel N' forward
a stage to bring a fresh part of the paper in line with the marking pencil. The
reels N. N¹ are held in tension by the springs and pinch unts T. T, the previous
marking on the paper having been moved clear of the sight glass which is in front,
though the marking when done can be seen by the person weighing the goods_and
before removing them from the scale platform, there being a rigid backing U to
ensure the prominent marking on the paper.
The horizontal line markings on the paper are graduated to represent given
weights and the distance the pencil travels vertically across these lines will indicate
the weights the margin of the paper being marked to correspond to a scale of
markings exposed to the man weighing or receiving the goods, said scale being next
a glazed window behind which the pencil moves. The number of vertical pencil
lines will indicate the number of weighings when the tapo paper is removed, but
by the index or counter K the total weighings over a given period can be seen.
The lever Q follows the rod C until it rests upon the stop Q' drawing the paul S
into a fresh tooth of the roel N' ready for moving the paper over at the next up
motion of the rod C, this being effected by the rise of the platform and rod A when
the weighed goods have been lifted or removed from the scale platform.

page_text: As soon as the tally has depressed the levers W, W it passes clear and allows
the lovers W, W to return to their normal positions under the action of the
weight 7 so that the stop or catch X moves into position for re-engaging under
the black Y when the rod C returns consequent upon the removal of the weight
from the platform.
We are aware that weighing machines of the kind herein described in which a
break exists between the platform rod and the indicating mechanism have been in
use prior to the date of our application horeof, and we make on claim to any part
which forms the subject of prior Patents but,
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed we declare that what
we claim is :—
The particular arrangement of appliances shown on the annexed drawings, by
which after the goods to be weighed are placed on the platform a tally or token
releases a holding claw to allow a prepared paper to be marked to indicate the
weight and record the number of weighings in combination with the dial mechanism,
said paper being shifted at each uprising of the platform after the weighing has
been effected, by crank and paul as and in the manner described.
