Improvements in Scales for Automatically Weighing and Registering
the Weight of Railway Vehicles.
I, EDWARD H. AMET, residing at No. 12, Park Place, in the City of Chicago, in
the County of Cook and State of Illinois, one of the United States of America.
Electrical Engineer, do hereby solemnly declare the nature of my 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 automatic scales for weighing rail-road cars and printing
the weights thereof.
The invention is designed to automatically weigh and record the weights of the
several cars coupled in a train without stopping the train, the weighing and recording
the weight of each car being done while the car coupled in the train is drawn
over the scale platform at a reasonable speed, so that a whole train of cars may be
weighed very quickly and easily. As the cars in a train vary materially in length,
provision is made by my invention to weigh with equal facility short or long cars.
The invention consists in the novel devices and novel combinations of parts
and devices herein shown and described, and more particularly pointed out in the
claims.
In the accompanying drawings, which form a part of this Specification, and in
which similar letters of reference indicate like parts,
Figure 1 is a side elevation or diagram view of a device embodying my
invention.
Figure 2 is a partial plan view.
Figures 3 and 4 are sections on lines 3-3 and 4-4 of Figure 2, respectively.
Figure 5 is an enlarged sectional view of the dash-pot, which is connected to the
scale beam or lever, and showing also the variable counterpoise.
Figure 6 is an enlarged detail view of the paper-feed rolls and rubber disk carrying
the carbon-paper.
Figures 7 and 8 are enlarged detail sections taken on lines 7-7 and 8-8,"
respectively, of Figure 6.
Figures 9 and 10 are enlarged detail views of one of the levers adjacent to the
track rail, so as to be operated by the car-wheels as they pass along on the road.
Figure 11 is a detail elevation of the lever which raises the impression hammer or
block, and
Figure 12 is a section on line 12-12 of Figure 9.
In Figure 1 of the said drawings, A represents a scale-platform having rail-road
track rails a thereon, which connect with the rails a¹ of the track leading to
the scale.
B is the connection from the scale-platform, and B' is the scale-beam. The scale,
its platform, and beam are or may be of any suitable construction known to those
skilled in the art or now commonly in use, and of course need no detailed illustration
or description.
C is the type wheel, the axle or shaft c of which is journaled on friction wheels c',
the shafts c² of which are journaled upon friction wheels c³ to still further diminish
the friction as shown in Figure 3. The shaft c is furnished with a gear 4 which
meshes with a rack b, connected by a pivoted link 615 with the scale beam B' or other
moving part or lever of the scale, so that the movement of the scale platform will turn
the type wheel.
The type wheel C should be made as light as possible, consistent with its necessary
strength and diameter, so that it may have as little inertia as possible to the end that

page_text: the inertia or momentum of the wheel may not cause errors in the weighing operation.
The type wheel may be of any suitable construction. One good construction is to
make it of light well seasoned wood surrounded by a thin metal band or tire, to which
an electrotype strip or band having the figure types thereon is attached by soldering
or otherwise. By making the type for printing the weights on an electrotype strip
of copper or other soft metal I am enabled very easily to properly adjust the position
of the type in respect to each other and in relation to the variable counterpoise so
that each type or figure will be in the right place to indicate the true weight. As
this may be done by simply stretching the electrotype strip in such parts as may be
required: The copper electrotype band of the printing wheel may be coated on the
outside with nickle by electro-plating, in order to harden and give greater strength
and body to the type.
In Figure 1 the scale beam B₁ is connected to a variable counterpoise D. This
variable counterpoise may be made of a coiled spring or any other suitable device. I
find, however, in practice that the tension of the coil spring is subject to more or less
variation, and to prevent the errors incident thereto I prefer to employ a variable
counterpoise consisting of a pendulum balance. The pendulum balance D has a rigid
arm d, pivoted at d to the frame E. The upper or short end of the arm & terminates
in an eccentric arc-shaped head d², to which is secured a flexible band d³, preferably
a thin flat steel band. The curve of this eccentric is such as to give equal or
approximately equal steps to the index scale d and to the type wheel C. The motion
of the counterpoise D is communicated to the type wheel through the eccentric are-
shaped head d², strap d³, lever d', link d', scale-beam B', and rack b, connected to
the scale beam, which rack meshes with the gear c¹ on the shaft of the type wheel,
the counterpoise D being of course raised or moved by the weight on the scale
platform. The flexible band or strip d³ is connected to the scale beam B¹, preferably
through an intermediate lever d³, pivoted at de to the frame E. The lever d³ is
connected to the beam by the pivotal link d'. I prefer to connect the variable
counterpoise to the long end of the scale beam, as shown clearly in Figures 5 and 1.
F Figure 5 is a dash-pot, vessel or cylinder, and F' is the disk or piston which moves
therein to steady the movement of the scale beam and of the type wheel, which is
operated therefrom. The disk or piston F' has two ports ff, furnished with valves fif¹,
one opening up and the other down, and which are held close by springs f² 2, so
that when the piston is moving either up or down one of these valves may open more
or less against its spring, and thus diminish the resistance of the dash-pot when
the scale beam is moving quickly. By thus combining a dash-pot having spring-
closed ports in its piston with the scale or scale beam I cause the scale beam to move
steadily, and at the same time to come to a true balance very quickly, both of which
results are very important in order to produce a successful and practical scale for
automatically weighing cars while moving in a train over the scale platform. The
tension of the springs 2 is regulated by set screws f³, threaded in the brackets f^.
In Figures 41 and 3 G is the impression block or lever, pivoted at g to the
frame E, by which the type wheel C is made to print the weight of each car upon
the paper strip after the scale beam reaches the true balance and turns the type
wheel to the proper point to indicate or print the weight of the car. This impression
lever or block is raised by a car wheel operated lever G', located near the middle of
the scale platform, adjacent to one of the rails a thereon, so that the wheel of the car
will depress or operate the lever as it passes along. The car wheel operated lever G¹
communicates motion to the impression lever G through any suitable connecting
mechanism as, for example, a link g', bent lever g², link g³, bent lever y*. link gỗ, and
lever G². The lever G2 (see Figure 11) is provided with a spring G³ to move it
back out of the way of the impression lever G as soon as the car wheel passes off of
the lever G¹. The impression lever G is held in its retracted or elevated position by
a trigger or pawl K. The pawl K is pivoted to the frame E and is held in place by
a spring K
A spring G actuates the impression lever or block to make the
impression the moment the trigger or pawl K is moved to release said impressio.
A

page_text: lever. The pawl K is operated at the proper moment to release the impression
lever G by means of devices N N¹, located at each end of the scale platform adjacent
to one of the rails a, so that said devices or levers are depressed or actuated by the
wheels of the car as it passes along. The levers or devices N N¹ are so located or
so constructed or arranged that if the car is a long one the front wheel of the car
may give the necessary final impulse to the lever N¹ at the exit end of the scale
platform before passing off the same, while if the car on the platform happens to be
a very short one the front wheels of the next succeeding car will give the necessary
final impulse to the lever N at the entry end of the scale platform before the front
wheel of such succeeding car passes onto the platform. By this means I am enabled
to weigh with equal facility long or short cars coupled in a moving train, and whether
the cars approach the scale platform from one direction or the other.
The car wheel operated devices or levers N N¹ may be of any suitable form or
construction and arranged in any suitable manner embodying the principle or mode
of operation above described. A variety of different forms of construction which may
readily occur to those skilled in the art may be employed. I prefer, however, to
make the levers N N' of a long bail-shape and to mount or pivot them so that one
part of the lever will project on the scale platform and the other part on the track
beyond the scale platform, such as shown in Figures 1, 9 and 10. The long bar
portion n of the lever N¹ is thus adapted to be depressed by the front wheel of a long
car, whilst the rear wheel thereof which is just approaching the scale platform,
may strike the similar long bar n of the bail-shaped lever N at the other end of the
scale platform. The shaft or pivot n' of each of the levers N N¹ is mounted in loose
or open bearings n², so that when the bail lever is depressed by a wheel on the scale
platform the end or portion of the lever which is mounted on the rigid frame work or
track outside the scale platform will sustain no part of the weight of the car.
error in the weight will thus be occasioned by the fact that one end or part of the
bail lever N or N₁ is mounted or supported outside of the scale platform which I
deem to be the preferable way of mounting or pivoting the bail levers N N¹. Each
lever N N has a short arm n³, which is connected by any suitable intermediate
mechanism with the ratchet or count wheels P P', (see Figure 3,) the shafts p p of
which carry cam wheels p'. which actuate the impression lever, releasing pawf or
trigger K. The pawl K is actuated at the proper time by the cam wheels p¹ p²,
through the levers p² p², connecting bar p³, and link p, which is pivoted to the
pawl K.
12
No
The mechanism for communicating motion from the short arms n³ of the bail
levers N N to the ratchet or count wheels may preferably consist of links n², bent
levers.n, links no, bent levers n', links n³, furnished with coil springs nº, slides, n10,
carrying pawls ", which engage the teeth of the ratchet or count wheels P P¹
Springs n serve to keep the pawls n in place, and springs n¹³ serve to retract
the slides no, and thus raise the bail levers N N after each impulse imparted
thereto by the passage of the succeeding wheels of the cars. The springs n serve
to prevent any excessive strain being put upon the mechanism of the car wheel
operated levers N N¹. The cam wheels p' are furnished with a projection or
cain p, one for each four teeth of the ratchet wheels P P¹, so that the pawl K
will be moved at each fourth impulse of the levers N N¹, the apparatus being
designed for weighing cars having four wheels on a side or running on each rail.
Each of the shafts p is furnished with a pointer p, which indicates on a dial p
the position of the tripping cams or projections p³ in relation to the ratchet or
count wheels P P and to the number of wheels of the car that have passed over
the scale platform. These pointers and dials are a matter of convenience in
setting the apparatus so that the camp will release the impression hammer at
the proper time, especially as the number of the wheels on the locomotive and
tender is usually different from the number of wheels on a car. After the loco-
motive which pulls the train of cars to be weighed and its tender have passed
over the scale platform the pointers p should both be set at number, 3, or so that

page_text: one of the cams p³ will operate the levers p² at the next or first impulse imparted
to each of the levers N N¹ by the front wheel of the first car. The front wheel
of the first car when it strikes the lever N at the entry end of the scale platform
will thus release the impression lever and print a blank or zero weight before any
of the wheels of the car get onto the scale platform. The front wheel of the car
as it advances to the middle of the scale platform will then again raise the
impression lever by operating the lever G'. After the remaining three wheels of
the car pass onto the scale platform the ratchet wheel P, which is operated by the
lever N at the entry end of the scale platform, will have been turned the distance
of three teeth, and consequently be in position to release the impression lever at
the next impulse which it may receive. Now, if the car happens to be a short
one, its front end will not strike the lever N at the exit end of the scale plat-
form until after the front wheel of the succeeding car strikes and again operates
the lever N, and thus release the impression lever and prints the weight of the
car, and when the front wheel strikes the lever N¹, as the now weighted car is
passing off, it will of course turn the ratchet wheel P¹, with which it is connected,
into position to move the pawl K and release the impression hammer; but the
printing will not be repeated, because the impression lever is already down and
will not be again raised until one of the hind wheels of the car reaches the middle
of the platform and strikes against the lever G¹, which, through its connections,
operates to raise the impression lever. If, however, the car happens to be a long
one, the front wheel of the car will strike the lever N¹, and thus give the necessary.
final impulse to release the impression lever, and so when the front wheel of the
succeeding car strikes the lever N it will of course turn the ratchet and cam
wheels into position for releasing the impression lever; but the printing will not
he repeated, because the impression lever is at this time already down and has
not yet been again raised by the passage of any of the wheels over the lever G¹
at the middle of the scale platform. The impression lever G, it will thus be seen,
is combined with and operated by either one of the car wheel actuated levers N N',
according as the car happens to be a long one or a short one.
The intermediate connecting mechanism by which the motion is communicated to
the impression lever or its releasing pawl from the levers N N¹ may be greatly varied
by skilled mechanics without departing from the principle of my invention; and I
desire it to be distinctly understood that my invention is not limited to any particular
form of such connecting mechanism. That, however, which I have above described
and shown in the drawings is the form of connecting mechanism which I prefer to
employ, and which I believe to be the best now known to me for practising my
invention.
The paper strip is wound upon a supply spool or reel R, and passes around over
the tension and guide pulleys 23 to the receiving reel or spool R'.
S represents a clock work or spring motor for driving the receiving spool R', and
thus causing the paper strip a to feed forward. The movement of the paper strip is
regulated by a pawl lever S¹, operated at intervals by the impression lever G, and
which engages a ratchet wheel S2 on the paper guide pulley. By this means
the paper strip is automatically fed forward the space necessary to receive the next
impression.
The impression of the type upon the paper strip may be simply an embossed or
indented impression produced by the direct action of the impression lever or block
upon the type wheel, or face of the type on the wheel may be automatically inked by
suitable inking mechanism; but the more improved means which I have devised for
this purpose consist of a revolving elastic disk T, preferably of rubber, carrying on
its under face a carbon paper t. The rubber disk T is stiffened by a card, board
disk T', the thin disks being placed together and clamped between the pulleys T² and
the screw threaded nut or washer T3. The pulley T2 is slowly revolved, so as to
continually present a new carbon surface to the type, by means of a band T4, driven
by a pulley T³, secured on the shaft of the guide roller r. (See Fig. 6.) The rubber

page_text: or elastic disk T serves also to cushion the blow of the impression lever or hammer
against the type wheel. The feed of the paper strip a and the revolution of the
disk T are thus automatically effected by the car wheel operated levers on the scale
platform through the impression lever G and the connecting mechanism before
described. The disk T, interposed between the type wheel and the impression lever,
it will be observed, only bears against the type at the instant the blow is struck by
the impression lever, so that it can occasion no friction or error in weight by such
contact with the type wheel.
Instead of communicating motion from the car wheel operated levers N N¹ to the
impression lever G or to the device for releasing the impression lever G by mechanical
means, as shown and described, electrical means and devices may be employed for
this purpose.
The shaft c of the type wheel C is furnished with a small pulley e from which a
light weight c is suspended by a cord c¹³ to counterbalance and compensate for the
friction of the shaft e and its bearings and of the gear and rack eb, as shown in
Fig. so that the weight recorder will not be influenced by the friction of these parts.
It will be observed that the weight is so combined with the axle c that it tends to turn
said axle in the same direction that it is turned by the rack 6 when moved by the load
upon the scale platform. By this means the apparatus is made much more sensitive
and the weighing very accurate.
