r s ibl. zoo-s) eighths of an inch long and one-eighth of an inch '1 in diameter, with oneand one-half inch wire leads.
The handling of units as small as this in the large quantities necessitated by present manufacturing methods introduces serious problems.
In a radio receiver'several resistance units of the same physical characteristics, but of different resistance values, may be required, and as the resistance value of the unit is usually indicated by a code marking on the'body ofthe unit, the need.
-for some practical manner of expediting the han- 20 dllng of the units in large quantities becomes apparent.
It is particularly difiicult to pick up individual units in rapid order as is necessary in production methods of manufacture, and if the units are but 25 haphazardly handled in bulk, their wire leads are apt to become bent which further prevents efiicient handling of the units in the assembly of radio receivers. g I
With a'view toward overcoming the disadvan- "tages of haphazard-handling of resistor units, this invention has as an object to provide means whereby large numbers of such small resistor units may be handled in orderly fashion and without danger of having their lead wires bent.
35 Another object of this invention is to provide means for holding the units in definite rows in such a manner that their code markingsare at all times visible, and so that removal of individual units is facilitated. I
40 Another object of this invention is to provide means for grouping definite numbers of resistor units or similar articles which means is so designed that a plurality of such groups may bereadily packaged for bulk handling.
45'- Another-object of this invention is to provide meansfor indicating at all times and at a glance the number of units present in a container hold- -closed by a cover 6.
ment of -the hereindisclosed invention maybe made as come within the scope of the claims The accompanying drawings illustrate several complete examples of the physical embodiment of the invention constructed according to the best 5 modes so far devised for the practical application of the principlesthereof, and in which:
Figure 1 is a perspective view of a box or container embodying this invention shown with its cover removed and containing only part of the 10 total number of units which the box is intended to hold; V Figure 2 is a perspective viewof. one of the inserts or carriers used to group the units in the embodiment, of the inventionshown in-Flgure 1, some of the units being in place therein;
Figure 3 is a perspective view similar to Figure 2, showing a modified form of insert or carrier;
' Figure 4 is a perspective view illustrating another type of carrier or insert;
- Figure 5 is a top plan view showing the manner 'in which inserts of the type shown in Figure 4 may be bundled for packaging. p
Referring now particularly to the accompanying drawings and especially to Figures -1 and 2,
the numeral 5 designates the main section or body of a box, the open top of'which is adapted to be The box is preferably formed of cardboard and has'an oblong shape with the body portion 5 thereof less than half the height of the cover.
- -On the outside faces of both side walls, a graduated scale I is delineated which provides indicia for determining the number 91 units contained within the box, not only when it is full to capacity, but also as the units are removed. In this manner, a close approximation of the number of units which a workman has on hand can be instantly determined at all times.
While in the drawings only one side of the box and its scale I is shown, as stated, both sides have such scales so that the number of units present in the box can be determined regardless which side the box is viewed from.
Contained within the base or body portion of 5 the box 5 are several inserts or carriers 8 in which the resistor units 9 are directly received. These inserts or carriers 8 by which the units are grouped are all identical in size and construction and have a definite number of individual pockets or compartments I 0 in which the lead wires l I at one endof the units are received.
The spacing between the individual pockets or compartments-I0 is 5 oh that adjacent units just contact each other so t at when all of the pockets o5 any suitable design and construction, but it has of a carrier 8 are filled, an unbroken row of units is present. If any one pocket mpty, the break in the row is immediately visi 1e so that in packing the cartons accuracy as to the number contained therein is assured.
The code marking for resistor units of this type generally 'eo ns ists of 'diflerent 'colored ,bandsimor side thereofaremovpd, 2,1 Q W QQ- W 1 sti ips [9 provide aligned cells or painted or otherwise delineatedon the bodies of the units as at l2. Marked in this manner, it is a simple matter to detect units of improper value which bear code markings of different combinations of colors. The assurance of accuracy as to uniformity of resistance values is thus a further advantage of this invention.
The individual carriers or inserts 8 may be of been found preferable to employ strips of corrugated paper board consisting of facings l3 glued to the opposite sides of a strip of corrugated in each instance, each insert has the samepredetermined number of individual pockets or compartments Ill. The number of compartments or pockets H] in each carrier or insert and the number of inserts contained within the box bear a.
definite relationship to the graduated scale 1.
In the embodiment illustrated in Figures 1 and 2, the box is intended to hold five hundred units. Thereare ten carriers or inserts and each has fifty pockets or compartments. In effect; the assembled inserts thus form a cellular core having five hundred cells and extending across the open top of the box. The scale I has fifty graduations, each one representing a transverse row of ten units. Consequently, if only ten transverse rows of units remain in the box, there are one hundred units present. In this manner the number of units in the box is at all times determinable at a glance.
' As pointed outhereinbefore, the height of the base or body portion 5 of the box is substantially less than that of the cover 6 and is such that the inserts or carriers 8 project above the top thereof thus making the units mounted therein clearly visible upon removal of the cover which is deep.
enough to accommodate the full length of the units.
As will be apparent from, the description thus far, the'broad aspect of the invention resides in and 2. This retainer consists merely of a strip of stiff paper bent longitudinally to provide at least one and preferably two channels l6 having transverse wall portions IT. The wall portions H are perforated as at l8 at regular intervals to receive the lead wires ll of the resistor units, as
shown. The spacing between the outermost trans- Another simple manner of grouping predetermined numbers of resistor units is illustrated in Figure 4. In this instance, two parallel strips of corrugated paperl9 are secured to one face of o a wider flat strip of paper 20 so as to form in effect a strip of corrugated board with one face 'cketsedorge" ceive the lead wires of the units, as shown. While two'strips [9 are shown, a single strip-of sufli znt width may be utilized. With this form of reta. er or carrier, packaging of a number of groups is best done by rolling the retainer with the resistors therein into bundles and inserting the bundles into suitable boxes, as shown in Figure. 5.
From the foregoing description taken in connection with the accompanying drawings, it will be readily apparent to those skilled in the art that this invention provides novel and simple means for facilitating the handling of large numbers of small resistor units and like articles for sale and use.
