POCKET SCALE
James H. Wily, Bethlehem, Pa.
Application April 21, 1931, Serial No. 531,714
8 Claims. (Cl. 265-53)
This invention relates to improvements in a
small size scale designed for weighing articles
and packages of comparatively light weight such
as letters, parcels post packages and the like. It
5 is designed for use primarily as a pocket or desk
article and is therefore constructed and designed
so as to telescope into a comparatively small com
pass. The scale includes a case or casing, one end
of which may be weighted or provided with a
weight if necessary, and into which a beam mem
ber is adjustably movable. The casing is pro
vided with a pivotal support or fulcrum near one
end and the beam member is provided at its end
with means for engaging or supporting the article
to be weighed. The beam member may be en
tirely telescoped within the casing and is provided
with suitable designations indicating weight with
a suitable sight point which is preferably pro
vided bythe end of the case or casing.
The beam
20 member may be provided with a plurality of
spaced recesses so as to insure a more or less fixed
adjustment in certain deñnite positions.
in order to provide a greater range of weights
and permit telescoping the article into a smaller
Ul compass, the scale may be in the form of a plu
rality of cases or casings and a telescopic beam
member arranged therein, the smaller cases or
3
casings telescoping within the larger ones.
The parts of this article may be made of various
materials such as celluloid, paper, metal and the
like and may be made of one piece constructions
or of several pieces suitably secured and connected
together. The form of the case or casing may
vary as desired, as may the adjustable beam so

Referring now to the drawing, the numeral I
designates an elongated hollow case or casing
which is adapted to serve as the weight member
of a balance scale and which may be provided 15
within its extreme end with a suitable weight
member 2 which also serves as means for spacing
the two sides oi the case or casing apart to provide
a pocket or recess to receive the slidable beam
member 3. As shown in Figure l, this beam 20
member is in the form of a flat strip or piece of
material and provided with the elongated inter
mediate longitudinal slot 4 which is preferably
‘enlarged at suitable spaced intervals to provide
depressions 5. This beam is provided at its outer 25
end with a clasp or other suitable member 5
adapted to hold or support a letter ‘i or other
article to be weighed.
'
The casing I may be formed of the two side
members 8, see Figure 2, the upper and lower
edges of which may be bent inwardly as at 9 to
afford a spacing medium for the sides s and thus
provide the recess or socket for the beam mem
ber 3. A bolt or rivet I0 is passed through both
sides of the casing I at or near its outer or open 35
end and this bolt or rivet is also passed through
the elongated slot â in the beam member 3. This
pencil or other similar articles.
To the accomplishment of the foregoing and
40 such other objects as may hereinafter appear,
this invention consists in the construction, com
member I0 serves as a iulcrum or support upon
bination and arrangement of parts hereinafter
described and then sought to be defined in the
appended claims, reference being had to the ac
companying drawing forming a part hereof and
which shows, merely for the purpose of illustrative
disclosure, several embodiments of my invention,
it being expressly understood, however, that
various changes may be made in practice within
50 the scope of the claims without digressing from
other suitable member may be connected thereto
for purposes of support or suspension. It is to be
my inventive idea.
In the drawing
Figure l represents a side elevation of one form
of scale constructed to embody my invention with
55 the beam shown in its extended position.
which the scale is balanced and is preferably
headed on each end as at II to facilitate holding 40
by means of a person’s fingers. Or a bail or
noted that this bolt or rivet is located at or near
the center line of the article as a whole so as to 45
give a delicate balance.
The ends of the side members Ei oi casing i
may be cut away as at I2, see Figure l, and pro~
vided with the sight points I3 on which a read
ing is made of the indicia on the beam 3. These 50
indicia may indicate weight or may indicate the
postage rate. In addition, both the beam and
the casing may be provided with other indicia for
giving linear measurements so that the article
as a whole can be used as a measure and also a 55

ruler. The recess or opening I2 provides a ringer
hold for facilitating the withdrawal movement
of the beam member when it is in its innermost
position. The slot 4 in the beam member 3 and
the bolt or rivet IIJ cooperate to limit the inward
and outward movement of the beam member'
relative to the casing, and the beam member may
be ñxedly adjusted by having the bolt or rivet
fit Within any one of the depressions 5. In this
Due to the telescopic construction thereof, it
takes up a small amount of space and is readily
adjustable to accurately weigh articles of vari
ous kinds and weight, of course Within limits as
far as the weight is concerned. The construc
tion is particularly adapted for use as a pocket
postal weight scale to be carried in >the pocket,
purse or pocketbook by salesmen and the like.
It is obvious that it may also be used in the home
10 way it can be readily determined whether or not
additional postage is needed without the neces
or ollice.
sity of accurately weighing the article. While
the beam member is readily slidable and adjust~
able in the casing I, it is to be understood that
15 it iits suiiiciently tight enough to give sufficient
frictional engagement to insure the parts being
held in adjusted position against unintentional
member in the form of a casing open at one end,
a slidable beam member adapted to be moved 15
displacement.
In the form of article shown in Figure 3, the
20 construction is substantially the same as that
of Figure 1 with the exception that another' and
larger casing I4 is provided in Which casing I
and its beam 3 telescope. This gives provision
for greater variation in adjustability and ena
25 bles the device to be telescoped into a relatively
smaller compass as compared to its total ex
tended length. When the device is used as a
scale as shown in Fig. 1, one set of graduations
is used, and when the device is used as shown
30 in Fig. 3, the other set of graduations is used.
As the details of construction of this ligure are
substantially the same as those shown in Figure
1, it is not believed that any additional descrip
tion is necessary.
35
In the form of article shown in Figure 5, I
provide a casing I5 which is in the form of a tube
or cylinder closed at one end and open at the
other to receive the slidable beam member I6.
This beam member is shaped in cross section to
40 correspond to and fit within the tube or cylinder
I5. Its lit is sufficiently tight so as to insure
the parts against accidental displacement when
adjusted, this being due to the frictional engage
ment of the beam with the tube or cylinder. The
45 closed end of the tube or cylinder is provided
with a clasp I‘I or other suitable means for sup
porting the letter or article to be weighed. The
open end is provided with a plurality of rivets
I8 arranged diametrically opposite each other to
50 provide finger holds and also the fulcrum upon
which the scale as a whole pivots. It is obvious
that instead of two rivets I8, a single rivet may
be used passing entirely through the cylinder
from side to side, in which event the beam mem
55 ber I6 will be provided with a slot substantially
shown in Figures 1 and 3. This form of device
may be made in various shapes such as tubular,
square and polygonal. In this particular form
the adjustable beam member IB is weighted and
60 serves as the Weight member and counterweight
as well.
The operation of this device is obvious. The
article to be weighed is supported by the clasp
6 or I‘I and the movable member adjusted while
65 the scale as a whole is held by the fingers or
any other suitable support. When a balance is
obtained, a reading of the indicia gives the
weight of the article or the amount of the post
age required. Or the movable member may be
70 adjusted in any one of its ñxed adjustable po
sitions and the article weighed so as to deter
mine the maximum amount of postage required
for that particular article.
The article may be made of various materials
75 such as celluloid, cardboard, metals and so forth.
