Western Electric Company, Incorporated, New
York, N. Y., a corporation of New York
Application December 19, 1936, Serial No. 116,673
10 Claims.
v This invention relates to assembling apparatus
and more particularly to apparatus for assembling
electrical fuses.‘
There is a class of electrical fuse devices com
5 prising a hollow body of electrically insulating
and ?reproof material within which is housed a
wire or strand of relatively easily fusible electri
cally conductive material, such as an alloy of
lead and tin, connected to conductive caps or
10 terminals mounted on the exterior of the body. In
one type of such devices the body may be a
cylindrical tube of compressed‘ ?bre glass, ceramic
material, molded plastic or the like through
which a fusible metal strand is passed axially and
15 connected to metal plugs in the ends of the
tubes.
v
An object of the present invention is to pro
vide an apparatus, simple and durable in struc
ture and rapid and reliable in operation, for pc
20 sitioning a strand in one or more hollow bodies.
One embodiment of the invention contem
plates an apparatus comprising one or more re
ceptacles to contain supplies of axially per
forated bodies, means to receive, orient and align
25 the bodies in a predetermined position and direc
tion, and means to propel a strand into position
within the bodies, and which may also include
means to sever the strands between members of
a sequence of bodies and to lock the severed
30 strand segments in place.
Other objects and features of the invention
will clearly appear from the following detailed
description of one embodiment thereof taken in
connection with the accompanying drawings
35 wherein the same reference numerals are applied
to identical parts in the several ?gures and in
which
Fig. 1 is a broken diagrammatic view in front
elevation of an apparatus constructed in ac
40 cordance with the invention;
Fig. 2 is a similar view on a larger scale of the
upper portion of the left hand end of Fig. 1;
Fig. 3 is a section on the line 3—3 of Fig. 2;
Fig. 4 is a broken enlarged view in right hand
45 end elevation of the apparatus of Fig. 1;

(Cl. 29—84)
closed is particularly adapted for use in the
manufacture of electrical fuse devices having a
body such as is shown best in Fig. 6, comprising
a cylindrical tube 20 of hard ?bre or other suit
able electrically insulating and ?reproof ma- 5
terial. The tube is closed at each end by metal
plugs 2|, 2| provided with coaxial outwardly ex
tending threaded stems 22, 22 on which are
metal washers 23, 23 and threaded nuts 24, 24.
The plugs 2| are locked to the body 20 by pins 26. 10
Each of the stems 22 has an axial bore 25 for the
reception of a fusible metal fuse wire 30.
Turning now to Figs. 1 to 5 inclusive, the ap
paratus (Fig. 1) comprises at the right a plurality
(here ?ve) of identically similar units A, B, C, D 15
and E, and at the left a core strand propelling
unit F. Units D and E only of the right hand
group will be described in detail, the others being,
as said, substantially identically similar. The
number of units in the right hand group may of 20
course be anything from one up to the practicable
limit. The machine as shown is hand operated
and its capacity is limited by the strength of the
operator.
It will be obvious however in the en
suing description that a substitution of mechani- 25
cal motive power for hand power would be within
the ability of any person fairly skilled in the art,
whereby to increase the capacity of the appa
ratus.
Units D and E, as best shown in Figs. 1 and 4, 30
are mounted on the base 28 of the machine, here
shown as a channel beam, laid horizontally, chan
nel open downwardly. A frame 29 comprising
such members, shown and not shown, as may be
necessary, is mounted directly on the base 28 and 35
carries a hopper 3| at the top, adapted to re
ceive and hold a plurality of the fuse bodies 20
with plugs, washers and nuts but as yet unpro
vided with fuse wires 30. A shaft 32 journalled in
the frame 29 passes horizontally through all the 40
units A to E inclusive.
In each unit it carries, '
keyed thereto or otherwise rigid therewith, four
suitably spaced, transverse, generally circular
discs 33, 34, 35 and 36. The two outer disks,.33
and 36, are spaced apart to just receive the ends 45
of the plug stems 22 of a fuse body between them
without binding. The two inner disks, 34 and 35,
are spaced apart to receive and support the fuse
bodies 20 near their extremities in suitable re
cesses or notches 38 cut radially at spaced inter- 50
Fig. '7 is a view analogous to Fig. 4 but showing
a modi?ed form of the invention, and
Fig. 8 is a fractional view on the line 8-8 of
vals into the peripheries of the discs 34 and 35.
Discs 31, 31, identically like discs 33 and 36, are
mounted outside the ?rst disc 33 of unit A and the

drop one by one into the recesses 38 of the discs
and are held thereby with the bores 25 of the body
with or lie with their axes just above the plane
of the top surfaces of the tools 43.
A carriage 62 is mounted to ride along the rail

A strand cutting and locking tool 43 is rigidly
left of the rail 60, over a second guide sheave T2
at the extreme right of the rail and over or once 15
or more around a driving pulley 13 between and
below the sheaves ‘H and ‘I2. The shaft 14. on
which the pulley "I3 is secured has also another
pulley ‘I5 rigid thereon. A belt 76 runs over
the pulley 15 and a third pulley 16 on a shaft 11 20
which can be rotated by a hand crank 18. A
mounted in the frame 29 between each two-units

them by forcible rotation of ‘the disc, the plug
35 being yieldingly forced into the recesses by the
compression spring 45. Thus the plug serves as
a yielding stop to hold the shaft 32 in each posi
tion of its indexing motion.
,

'
A lever 46 is secured to the shaft 32 beside the
disc 35 of unit D and has pivoted thereon 'a'
ratchet 4‘! adapted to enter its free end into the
recesses 38 of disc 35 under pressure of a ten‘
sion spring 48 attached at one end to the ratchet
and at the other end to the lever 46. The ratchet
is formed at its free vend to push the disc 35
and therewith the shaft 32 around in one direc
tion (counterclockwise as seen in Fig. 4) and
to cam out of a recess 38, when moved in the
other direction, to drop into the next recess 38.
50 At its ‘extreme outer end, the lever'46 has a .
link '49 pivoted thereto to be pivotable in the
plane of the lever. A second link 50 pivotable in
a plane at right angles thereto is pivoted to the
link 49 above and below is pivoted with freedom
55 to swing parallel to the lever 46 to a third link
5|. ‘The link 5| in turnris pivoted on the outer
end of a lever 52 whose inner end is rigidly se
cured to a shaft 53 mounted in the base 28 and
extending out in front of the base where an op
erating hand lever 54 is rigidly secured thereon.
Between each pair of discs 34 and 35 and be
low the tools 43, is mounted a chute 55 whose
upper and lower faces extend 'up between the
65 discs 34 and 35 in such wise as to strip the ?n
ished fuses from their seats in the recesses 38
and lead them away to any suitable receptacle‘
not shown.

The, unit F comprises a track member 60,

axis of the apparatus. A ‘horizontal slot 6| is
formed in ‘the front face to be coaxial’ with the
recesses 38 and notches 39,when these are in
their most frontward positions and are aligned
28, and running generally parallel to the main
A to E are ?lled with a supply of wireless fuse
bodies and the shaft 32 is indexed counterclock
wise (Fig. 4) by means of the lever 54 three
steps until the ?rst ?lled recess 38 is in the
extreme front position indicated at a: in Fig. 4.
There are then. in the apparatus illustrated, ?ve
fuse bodies, one in each unit, all in exact align 40
ment with each other, with corresponding notches
39 and with the needle 80, which latter thus has
a clear path in front of it from end to end
throughout the units A to E inclusive.
Lever 5| is then left stationary and crank 18
is turned clockwise (Fig. 1). This draws the
carriage 52 to the right and so pushes the needle
80 on through‘the ?ve fuse bodies until it pro
trudes beyond the last one at theright as indi
cated in dotted lines in Fig. 1.
The end of a 50
strand 30 of fuse wire is fastened to the hook
8|, being drawn ' from ‘a supply thereof not
shown. The crank 18 is then rotated in the re
verse direction (counterclockwise in Fig. 1) which
draws the needle 83 back into the groove BI and
withdraws it from the units A to E- at the same
time drawing a continuous length of the fuse
wire '30 through all ten bores 25.
Preferably, stops 82 and 83 are mounted on
the rail 60 to mark the ends of the proper re 60
ciprocato'ry motion of the ‘carriage 62.
The lever 54 is then operated to index the shaft
32 one step. During this operation each length
of fuse wire spanning a groove 4| is carried down
against one of the tools ‘43 which breaks the 65
wire between adjacent fuses and bends down or
clinches the broken ends over the ends of the
stems 22 as best shown in Fig. 5.
At the end of this one step advance of the
shaft 32, the ?rst set of ?ve complete fuses, with 70
their fuse wires locked in by being clinched over
at the ends, is entering the several chutes 55 to
be forced out of the discs 34 and 35 on the next
step and into the chutes to be carried away.
Meantime a ‘second set'o'f ?ve empty bodies is in
3
2,132,242
position to receive the needle and thereby the
required fuse wire.
In a modi?ed form illustrated in Figs. '7 and 8,
the tools 43 are omitted, the discs 33 and 36 are
formed as gears and idler pinions 84 are mounted
in the frame 29 to mesh with these'gears. These
parts are so dimensioned and disposed that the
needle 85 or strand 30 during the threading
operation passes between two of the teeth of disc
10 33 or 36 and a corresponding tooth of pinion 84
just about to enter the same space. Then when
the shaft is next indexed, the wire 30 is carried
down and is mashed flat by the gears just outside
the ends of the stems 22. The parts are so propor
15 tioned that this action will mash out the wire to
be too broad to pass through the bores 25. The
parts may further be formed to cut away the
short segment of wire left between the mashed
portions and between the discs 33 and 36, or this
may be knocked away and collected by a small
chute and collector 85 located between these discs
as the chute 55 is between the discs 34 and 35.
In either form of the apparatus, at each re
ciprocation of needle 85) and ensuing actuation of
25 lever 56 five fuse bodies have fuse wire inserted
therein and locked in place and the attendant has
only to operate crank 13, attach wire to the needle
80, operate the crank and actuate the lever 54, all
in cyclic repetition.
