. catch which projects through the opening 20 1
constitutes a toe 22. The extremity of this
toespresents an inclined rear face, while the
extremity of the tooth 18 presents an in-
5 lined forward face. The toe is adapted to
normally engage the tooth in the manner
shown in Fig. 1, which, evidently, locks the
arm 3 against a downward movement. The
catch is normally held in this position by
to means of a leaf spring 23 attached to the
wall of the handle as indicated. The rear
portion of the catch is formed with an up-
wardly projecting tail 24 which is adapted to
be pressed by one's fingers when it is desired
15 to release the arm 3 from the catch.
It should be understood that when it is de-
sired to weigh a substance in the pan, the
weighing mechanism is released from the
catch in the manner suggested. The tooth
20 18 will then move toward the right and pass
over the toe 22. When the pan is emptied,
the spring 10 will return it to its normal posi-
tion, and in doing so, the inclined faces of the
tooth 18 and toe 22 will slide over each other,
25 so that the catch will operate automatically
to lock the pan again to the handle.
I provide an arrangement whereby the
handle may carry a light which may be lit at
will so at to illuminate a dark corner or closet
30 where the scoop may be in use. For this
purpose, the interior of the tubular body 2 is
provided with a dry cell 25, in the end of
which a small incandescent light 26 is at-
tached. This light is covered by a suitable
35 globe 27, and a circuit through the light is
adapted to be closed at will by a push button
28 which is preferably set into the material
of the handle, as indicated. The end of the
handle remote from the pan at which the
40 light 26 is located, is formed with an opening
29 through which the rays of light from the
lamp pass. This end of the handle is pro-
vided with a loop or bail 30, of wire, which
enables the scoop to be hung up when not in
45 use.
Instead of applying the weight to the
spring in the manner described above, I may
provide an arrangement in which a compres-
sion spring is employed. In this connection,
5c referring especially to Fig. 2, the inner end of
the handle 31 is provided with a hood 32,
similar to the hood described above. To the
lower portion of this hood near its point of
connection with the handle 31, an arm 33 is
55 pivotally attached by a pivot pin 34. The
lower portion of the hood is extended so as to
form a foot 35 to which a head 36 is pivoted.
Upon this head rests a compression spring
37, of helical form, as shown. The upper ex-
6o tremity of the arm 33 carries an adjusting
screw 38, the inner extremity of which is
formed into a head 39, against which the up-
per extremity of the spring 37 thrusts as
shown. Beyond the adjusting screw 38 the
65 end of the arm 33 is offset downwardly andformed into a yoke 40 which is attached to
the rear portion of the pan in any suitable
manner. As in the preferred form, the up-
per portion of the hood 32 is formed into a
scale 41, with which co-operates a pointer 42. 70
This pointer is pivoted at 43 in the lower por-
tion of the hood. The arm 33 is provided
near its pivot pin 34 with a downwardly pro-
jecting tooth 44, and this tooth is connected
pivotally by means of a link 45 with the 75
pointer 42 at a point above the pivot 43
thereof. From this arrangement it should
be understood that when a weight is in the
pan, the arm 33 will be deflected downwardly
and this will move the tooth 44 rearwardly, 8o
and the movement of the tooth will be com-
municated, by means of the link 45,. to the
pointer 42, so that the pointer will rotate
from left to right on the scale at 41. The
spring 37 normally holds the arm 33 against 85
the upper edge of the hood at the point 460, so
that this point of the hood operates as a stop
to limit the upward movement of the arm.
In order to enable the arm 33 to be locked
rigidly to the handle, I provide a catch 47 90
which is very similar to the catch 19 de-
scribed in connection with the preferred
form. This catch is pivoted to the under
side of the handle and is formed with a toe 48
which proj ects through the wall of the handle 95
so as to engage the tooth 44.
A leaf spring 49 normally holds the toe 48
in engagement with the tooth, and by de-
pressing the tail of the catch the toe may be
thrown out of engagement therewith. The 1oc
rear faces of the tooth and toe are inclined,
as in the preferred form of the catch, so as to
enable the catch to lock the pan automatic-
ally when it is returned by its spring after be-
ing emptied. 105
In both the forms described, the adjusting
screws enable the condition of the spring to
be accurately adjusted.
Having thus described my invention, I
claim as new and desire to secure by Letters Tic
Patent:
1. In a weighing scoop, in combination, a
handle having its inner extremity formed
into a hood, an arm constituting a bell crank
lever pivotally mounted in said handle, a pan 115
carried by said arm, said arm having a short
arm projecting therefrom, a spring connect-
ing said first arm with said hood and adapted
to support a weight in said pan, a pointer
pivotally mounted within said hood and I2
adapted to co-operate with a scale and con-
necting said arm with said pointer for actu-
ating the same.
2. In a weighing scOOP, in combination, a
handle having a hood formed at the inner ex- 12
tremnity thereof, an arm pivotally mounted
in said handle, a pan carried by said arm, a
spring connected with said arm and adapted
to support a weight in said pan, said arm
having a laterally projecting tooth near the 13c%a
