the beam pivotally attached to its upper end. A suitable flexible connection m is
secured to the inner end of the beam and also to the drum on the shaft d, and is
wound on said drum so that when the inner end of the beam moves up the shaft d,
and finger c, will be revolved.
n, is a scoop of any suitable shape in cross section and having the open end with
the usual cutting edge. This scoop is usually in the form of a closed box having
one open end. This scoop is suitably pivoted and balanced in the forked end of
the beams. This scoop can be suitably pivoted between its ends in the ends of
eaid fork. If desired the. scoop can be removably pivoted in the fork by means
of the U-shaped spring wire o, having its outer ends passing inwardly through
apertures in the beam fork ends so as to turn therein and so that the projecting
points thus formed can be sprung into and out of the depressions p, in opposite
sides of the scoop. The U-shaped wires extends along the outer sides of the arms
of the beam fork and from thence across the end of the scoop. This transverse
portion of the U-shaped wire o, can have a plate 9, suitably secured thereto to fit
the inner end of the scoop. By this means the scoop can be removed and the

end of the plate q, and thereby hold the scoop in its normal operative position in
continuation of the scoop handle so that the article can be employed for scooping
up material to fill the scoop proper with the desired quantity. This catch can be
provided with the downwardly extending handle end s, so that the catch can be
released by means of the finger and the scoop allowed to drop to the vertical
position so that the material therein can be weighed. The scale beam is free to
move and consequently the weight of the material in the scoop draws down the
outer end of the beam against the tension of the spring and consequently the
indicating finger is moved around on the dial and indicates the weight of
the material in the scoop. This scoop can have a closed or sieved bottom as
desired.
If desired a small indicating finger and scale can be provided suitably connected
with the moving parts of the shaft d, or the scale beam so as to indicate every
complete revolution of the shaft d. This auxiliary indicating device is only
intended for use where my invention is applied to shovels or where heavy loads are
to be weighed and the main indicator is liable to make more than one revolution.
Fig. 1 shows this auxiliary indicating device operated by the guiding drum which
directs the connection m up to drum d. This guiding drum carries an indicating
finger over a scale at the exterior of the handle, the guiding drum and drum d
having different diameters so as to rotate at different speeds.
Where this present invention is to be employed for shovels or other large
implements a rearwardly extending handle u, from the enlargement in the scale
beam handle can be employed and several springs can be connected to act on the
scale beam.
The utility, simplicity and durability of this invention. are obvious.
It is evident that various changes might be made in the forms, arrangements and
constructions of the parts described without departing from the spirit and scope of
my invention. Hence I do not wish to limit myself to the exact construction
herein set forth, but consider myself entitled to all such changes as fall within the
spirit and scope of my invention.

I, PETER JONAS BERGQUIST, of 'Fargo, Cass County, North Dakota, United
States of America, Merchaut, 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 certain improvements in weighing scoops or shovels.
The object of the invention is to provide an improved automatic weighing scoop,
exceedingly strong, simple and durable in construction and composed of a minimum
number of parts whereby material can be scooped and shoveled up and weighed.
The invention consists in certain novel features of construction and in combination
of parts more fully aud particularly described hereinafter and pointed out in the
claims.
Referring to the drawings filed with my Provisional Specification,
Figure 1, is a perspective view showing the scoop proper in dotted lines in its
normal operative position, the handle of the scoop being broken away, and showing
the interior construction thereof.
Fig. 2, is a side elevation of the scoop showing the scoop released and swinging
in an upright position, a different form of scoop being shown, also a somewhat
different form of handle being shown.
Fig. 3, is a detail side elevation showing the scoop handle, a balanced fork or
beam to receive the scoop, the scoop not being shown.
Fig. 4, is a detail plan view of the fork of the beam, and the scoop in its
weighing position.
In the drawings the reference letter a, indicates the handle of the scoop. This
handle is made hollow and of a suitable length for the purpose intended. At its
outer end the hollow handle is provided with an enlargement, the exterior of which
is provided with a graduated face or dial b, over which the indicating finger or
hand is arranged to travel.
d, is a transverse shaft on which this finger c, is mounted. This shaft extends
transversely through the enlarged portion of the handle and is suitably journalled
therein.
e, is a drum rigid on the shaft d, within the handle.
f, is a coiled spring having one end attached to the shaft d, and the other end to
the freely rotatable disc g, having the ratchet teeth on its exterior.
h, is a pawl secured to the interior of the handle and engaging the ratchet teeth.
This spring is arranged to return the shaft d, and indicating finger to zero and
yieldingly hold the same in this position and the spring can be varied in tension by
turning the disc so as to properly balance and hold the parts. In this connection
it should be observed that the ratchet wheel is rotatable independently of the shaft
and its drum e, and that the pawl h, normally holds the wheel against rotation so
that the tension of the spring on the shaft can be easily controlled by rotating the
ratchet wheel in one direction or the other.
i, is a scale beam longitudinally arranged within the handle and extending
downwardly through the open end of the handle and provided with a forked outer
end j. The scale beam between its ends is fulcrummed or pivoted at k, on suitable.
journals in the handle, so that its outer and inner ends rock vertically. The inner
end of this beam is suitably attached to the spring 1, secured within the hollow
handle. This spring is preferably in the form of a retractive coiled spring secured
usually at its lower end in the enlarged portion of the handle and having the inner
end of the beam pivotally attached to its upper end. A suitable flexible con-
nection m,
is secured to the inner end of the beam and also to the drum on the

page_text: shaft d, and is wound on said drum so that when the inner end of the beam moves
up the shaft d, and finger c, will be revolved.
n, is a scoop of any suitable shape in cross section and having the open end with the
usual cutting edge. This scoop is usually in the form of a closed box having one open
end. This scoop is suitably pivoted and balanced in the forked end of the beams.
This scoop can be suitably pivoted between its.ends in the ends of said fork. If
desired the scoop can be removably pivoted in the fork by means of the U-shaped
spring wire o, having its outer ends passing inwardly through apertures in the beam
fork ends so as to turn therein and so that the projecting points thus formed can be
sprung into and out of the depressions p, in opposite sides of the scoop. The
U-shaped wire extends along the outer sides of the arms of the beam fork and
from thence across the end of the scoop. This transverse portion of the U-shaped
wire o, can have a plate q, suitably secured thereto to fit the inner end of the
scoop. By this means the scoop can be removed and the device employed to
weigh any article by permitting the U-shaped frame to hang in the vertical
position and placing material or article to be weighed in the pan or plate q.
'r, is a suitable scoop catch mounted at the open end of the scoop handle on the
fork of the scale beam and arranged to engage a stop or shoulder on the outer
end of the plate q, and thereby hold the scoop in its normal operative position in
continuation of the scoop handle so that the article can be employed for scooping
úp material to fill the scoop proper with the desired quantity. This catch can be
provided with the downwardly extending handle ends, so that the catch can
be released by means of the finger and the scoop allowed to drop to the vertical
position so that the material therein can be weighed. The scale beam is free to
move and consequently the weight of the material in the scoop draws down the
outer end of the beam against the tension of the spring and consequently the
indicating finger is moved around on the dial and indicates the weight of
the material in the scoop. This scoop can have a closed or sieved bottom as
desired.
If desired a small indicating finger and scale can be provided suitably connected
with the moving parts of the shaft d, or the scale beam so as to indicate every
complete revolution of the shaft d. This auxiliary indicating device is only intended
for use where my invention is applied to shovels or where heavy loads are to be
weighed and the main indicator is liable to make more than oue revolution.
Fig. 1 shows this auxiliary indicating device operated by the guiding drum which
directs the connection m up to drum d. This guiding drum carries an indicating
finger over a scale at the exterior of the handle, the guiding drum and drum d
having different diameters so as to rotate at different speeds.
Where this present invention is to be employed for shovels or other large
implements a rearwardly extending handle u, from the enlargement in the scale
beam handle can be employed and several springs can be connected to act on the
scale beam.
The utility, simplicity and durability of this invention are obvious.
It is evident that various changes might be inade in the forms, arrangements
and constructions of the parts described without departing from the spirit and
scope of my invention. Hence I do not wish to limit myself to the exact
construction herein set forth, but consider myself entitled to all such changes as
fall within the spirit and scope of my invention.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
