Weighing and Price Scales.
I, GUSTAVE LUNDBERG, of Logan, in the County of Cache, and Territory of
Utah, United States of America, Gentleman, 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 improvements in weighing scales by means of which
the weight and the price of an article can be ascertained by a single operation.
In carrying out the invention I make use of a supporting frame having a pivoted
beam which has at one end a receptacle upon which the article to be weighed is
placed and at the other end a movable graduated cylinder which acts in
conjunction with an adjacent scale plate to determine the weight and the price
of an article; there being a definite proportion and relation between the
graduations on the cylinder and the means employed to rotate said cylinder and
move it longitudinally.
Referring to the drawings,
Figure is a side elevation of a weighing and price scale constructed in
accordance with my invention;
Fig. 2 is a sectional view through the line of Figure 1 ;
Fig. 3 is a view showing a portion of the beam, cylinder, scale-plate and screw
for moving the cylinder; and
Fig. 4 is a detail perspective view of a portion of the scale-plate.
The figures indicating cents per pound.
A designates the base to which the scale-beam supports or uprights B B are
rigidly secured, the scale-beam, C, having trunnions formed thereon which bear in
recesses in the upper ends of the uprights.
Upon the base between the uprights is located a block D to which are pivoted
one of the ends of the rods E and F, the other end of said rods being pivoted to
the pan supporting frame G located at one end of the scale-beam and to a
supplemental weight-frame, H, at the other end of said scale-beam. These rods
hold the frames G and H in a vertical position. Upon the frame G is carried a
receptacle or scale-pan I, upon which the article to be weighed is placed, and
within the frame H is located a pan K upon which scale-weights may be placed
when the article to be weighed exceeds the capacity of the movable graduated
cylinder carried by the scale-beam.
The scale-beam C is made up of parallel bars L L, which are connected to each
other at each end as shown in Fig. 3, and between these bars near their supporting
trunnions is rigidly secured a block M apertured for the passage of a screw N
which is attached to the graduated cylinder O, the opposite end of said cylinder
being supported by a shaft P which passes through a suitable bearing formed on
the end of the scale-beam. This shaft is turned to rotate and move the cylinder
by a hand-wheel Q, the weight of which acts in unison with said cylinder.
The graduated cylinder is provided at each end with a head R, and these heads
are connected to each other by a plate S, said plate having a depending portion
with an off-set which bears against the underside of one of the bars L which make
up the scale-beam, and to this plate is attached a scale-plate T the lower edge of
which bears against the upper edge of the bar L; such construction holding the
parts S and T against rotation but permitting them to have a longitudinal
movement with the cylinder. The end of the scale-plate nearest the hand-wheel
has a space upon which is marked the figures or letters indicative of the standard

page_text: of weight employed, and the balance of the spaces on said plate are lettered or
numbered to refer to different prices per pound or other standard weight.
The circumference of the graduated cylinder at the end adjacent to the hand-
wheel is divided into a proportionate scale which acts in unison with the pitch of
the screw and weight of the cylinder, and the balance of the cylinder is numbered
or lettered on a line with the numbers or letters on the scale-plate and represent
aliquot parts thereof, by which arrangement it will be noted that not only the
weight of an object can be readily ascertained but the price of the same will be
indicated.
In practice the weighing and calculating device may operate as follows: When
the cylinder O is turned so that the head R will bear against the block M the beam
should balance. Should a purchaser desire a certain weight of an article the
hand-wheel is turned until the figure or letter in the column U representing said
weight is at the edge of the scale-plate, when the article can be weighed in the pan,
and the dealer by noting the letter or mark on the cylinder located adjacent to the
division on the scale-plate denoting the price of the article at the standard weight,
can at once note the price of the aliquot part. As for instance 7 ozs. of an article
at 20 cents per pound would cost 9 cents as indicated.
For different scales or tables of weights and measures the position of the
divisions will be varied both on the scale-plate and cylinder, and there can also be
a variation in the pitch of the screw and weight of the cylinder.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1. The combination with the supporting frame, of a pivoted beam carrying
a revoluble and longitudinally movable graduated cylinder and a non-rotatable
scale-plate engaging with the cylinder so as to be moved therewith upon the
scale-beam, substantially as shown, and for the purpose set forth.
2. The combination with a pivoted beam, of a rotary cylinder adapted to be
moved longitudinally upon the beam, said cylinder carrying a non-rotatable
scale-plate, said plate and cylinder being suitably divided and marked to indicate
the weight of an article placed on the opposite end of the scale-beam from the
cylinder substantially as shown, and for the purpose set forth.
3. The combination with a pivoted scale-beam, of a rotary and longitudinally
movable cylinder carrying a peripheral scale indicating weight and a series of
peripheral scales indicating the prices of predetermined quantities, and a scale-plate
spaced to correspond with the divisions and sub-divisions on the cylinder, said
plate being adapted to move longitudinally with the cylinder and held against
rotary movement by engagement with the scale-beam, substantially as shown, and
for the purpose set forth.
4. In combination with a pivoted scale-beam, a rotary shaft having fixedly
secured thereto a cylinder, a block carried by the scale-beam and provided with an
aperture with which the spiral portion of the shaft engages, and a pan carried by
the scale-beam of sufficient weight to counterbalance the cylinder when it reaches
the limit of its movement towards the scale-pan, substantially as shown.
5. The combination with a supporting frame, of a scale-beam pivoted thereto
and provided at one end with a scale-pan and on the opposite side of the pivot with
a movable cylinder, said cylinder being fixedly attached to a rotary shaft having a
hand-wheel, said shaft having a spiral portion for engagement with a block carried.
by the scale-beam adjacent to its fulcrum, for the purpose set forth.
6. The combination in a weighing and price scale, of a scale-beam having an
open frame on one side of its fulcrum, the side bars of said open frame carrying a.
block apertured for the reception of a longitudinally movable and rotary shaft
having a spiral end portion, a graduated cylinder rigidly attached to the shaft
between the side bars of the scale-beam, said cylinder carrying stationary heads
which are connected by plates having bent ends which engage therewith, one of.

page_text: said plates also engaging with one of the side bars of the scale-beam to prevent the
rotation of the same, and a scale-plate carried so as to move longitudinally with the
cylinder and be held against rotation, substantially as shown, and for the purpose
set forth.
7. In combination with a scale-beam fulcrumed upon a supporting frame and
provided at one end with a platform which is hung therefrom, a pan mounted on
the opposite end of the beam, rods connected to the pan and platform and pivoted
to the supporting frame, a movable weight and price determining cylinder carried
by the scale-beam so as to be capable of both a rotary and longitudinal movement,
substantially as shown, and for the purpose set forth.
