FRANK C. HOWE, OF EL PASO, TEXAS.
WEIGHING-SCOOP.No. 852,182.
To all whom, it may concern:
Be it known that I, FRANK C. iown, a
citizen of the United States, and a resident of
El Paso, in the county of El Paso and State
5 of Texas, have invented a new and Improved
Weighing-Scoop, of which the following is a
full, clear, and exact description.
This invention relates to scoops, such as
used in stores or similar places in selling food
10 products such as flour, sugar, etc.
The general object of the invention is to
produce a scoop which will operate to weigh
the substance held therein, and the specific
object of the invention is to provide a weigh-
z 5 ing mechanism in connection with the scoop
which will give very accurate indications of
the weight.
A further object of the invention is to pro-
vide the handle of the scoop with a light
20 which may be lit at will so as to enable a
persons using the scoop to illuminate the im-
mediate surroundings of the scoop. This at-
tachment increases the utility of the scoop
where it is to be used in dark closets or under
25 similar conditions.
The invention consists in the construction
and combination of parts to be more fully
described hereinafter and particularly set
forth in the claims.
30 Reference is to be had to the accompany-
ing drawings forming a part of this specifica-
tion, in which similar characters of reference
indicate corresponding parts in both figures.
Figure 1 is a side elevation of the scoop,
35 the handle and weighing mechanism thereof
being shown in cross section; and Fig. 2 is a
view similar to Fig. 1, but showing only a
portion of the scoop and its weighing mechc-
anism, and representing a modified construc-
40 tion.
Referring more particularly to the parts, I
represents the body or pan of the scoop; this
pan is supported upon a tubular handle 2
by means of an arm 3 which is pivoted to the
45 handle on a suitable pivot bolt or pin 4.
While the principal portion of the handle 2
is tubular as shown, it will be seen that the
inner extremity of the handle is formed into
a hood 5 in which parts of the weighing mech-
50 anism are placed as indicated; and the upper
side wall 6 of this hood is formed in an arc,
the center of which lies in the axis of a pivot
pin 7, which pivot pin affords means for at-
taching a pointer 8 within the hood. The
55 end of this pointer 8 lies adjacent to the wall
6, and is visible through the wall 6 of thePatented April 30, 1907.
hood which, at this point, is formed of glass
or similar transparent material. This curved
wall 6 is formed with a scale which will give a
reading in columns, to indicate the weight 6o
carried in the pan 1. At its upper portion
the hood 5 is formed. with a projecting stop 9,
and near this point a spring 10, of helical
form, is attached. The lower extremity of
this spring is attached to an adjusting screw 65
11 -which is mounted in the aforesaid arm 3
as indicated. The upper extremity of the
spring 10 is not attached directly to the hood
5 but is attached to a head or pivot plate 12
which is pivoted at 13 to the hood as shown. 70
A head 14 is attached to the other end of the
spring, and through this head passes the
threaded shank of the adjusting screw 11, as
indicated. On the rear face of the pan 1
which lies adjacent to the hood a lug 15 is at- 75
tacked, which is normally held against the
stop 9 by the tension of the spring 10, as will
be readily understood. From this arrange-
ilent it should be understood that when a
substance is placed in the pan, the arm 3 will 8o
be deflected downwardly and the spring 10
will be extended.
In order to move the pointer S propor-
tionately with the degree of extension of the
spring so that the scale on the wall 6 may in- 85
dicate the weight within the pan, I pro-
vide the arm 3 with an upwardly projecting
finger or short arm 16, which arm is dis-
posed at the pivot 4, so that the arm 3, to-
gether with the arm 16, constitutes a bell 90
crank lever. The pointer 8 is extended be-
yond its pivot pin 7 to enable a link 17 to be
attached which connects the pointer with
the extremity of the short arm 16 as shown.
From this arrangement it should be under- 95
stood that when the pan is moved down-
wardly by the weight, the finger or short arm
16 is moved in the direction of the pointer 8,
and rotation of the pointer will take place
from left to right. In the position shown in io
Fig. 1, the pointer occupies its zero position;
that is, it will indicate that there is nothing
in the pan.
I provide means for locking the arm 3 rig-
idly to the handle. For this purpose, the 105
arm 3 is provided near the pivot bolt 4, with
a downwardly projecting tooth 18, and this
tooth is adapted to be engaged by a catch 19
which projects through a small opening 20
formed in the under side of the handle as in- i i
dicated. This catch 19 is pivoted at 21 to
the wall of the handle, and a portion of theSpecification of Letters Patent.
