Heretofore, cigars having perforated ends have on the line 3-3 of Figure 1.
Figure 4 is a top plan view of the machine with
been formed by inserting a pointed implement or
portions of the supply chute shown in horizontal
needle into the cigar, but the methods and ma
chines available for .performing the operation
have been relatively ine??cient and the operation
10 has been slow and tedious. Furthermore the
wrappers .of the cigars are frequently cracked or
torn during the perforating operation which not
only impedes the operation but also destroys the
cigars.

.
One object of my invention is to provide a
novel and improved machine of the general char
acter described whereby the cigars may be rapidly
fed in succession to a perforating mechanism,
then perforated and then successively and auto
2 matically ejected from the machine, whereby
large numbers of cigars can be handled and per
forated quickly and with a minimum of manual
handling.
'
Another object is to provide in such a ma
25 chine novel and improved means for successively
feeding or depositing the cigars in proper rela
tion to the perforating mechanism.
Further objects are to provide a machine of
this character having novel and improved means
30 for accommodating cigars of different length and
vlocating each cigar in proper relation to the per
forating mechanism, to ensure accurate perfora
tion of the cigar to the proper depth.
Another object is to provide novel and im
sectiim, approximately onthe line 5-5 of Fig

Speci?cally describing the illustrated embodi
ment of the invention the machine includes a
table A mounted on a suitable base B and having 25
a cigar supply chute arranged on the top thereof
to which the cigars are supplied from a hop—
per D.
In accordance with the invention, the cigars
are disposed in the chute C in horizontally super 30
posed relation and are fed or, deposited suc-.v
cessively onto the table A in proper position to
a perforating mechanism E which forms a hole
or perforation in one end of the cigar. After

Other objects of the invention are to provide
a novel and improved perforating mechanism
for machines of this character; to provide such
45 a perforating mechanism which shall include a
head for embracing and holding the end of the
cigar to be perforated and a needle movable rela
tively to said head into and out of the end of the
cigar while the latter is held by said head; where
by the head shall accurately center the cigar end
relatively to the needle; to provide a novel and
improved perforating needle including means for
heating it to facilitate perforation of cigars; and

’ opposed resilient metal walls 2 and 3 are secured
at their upper ends by bolts 4. The chute also
has end walls 5. The lower ends of athe side
walls 2 and 3 are normally influenced away from
each other by their inherent resiliency and are 45
adjustable toward each other by set screws 6
and ‘I mounted in cleats 8 on the standards i.
The lower end of the wall 3 is also movable toward
and from the adjustable wall 2 for the purpose
of controlling feed or‘deposit of the cigar on the 50
table A by means of a reciprocating arm 9 coop
erating with a cam l0 mounted on the wall 3.
When the wall 3 is moved away from the wall 2
as shown in Figure 3, the lowermost cigar is per
mitted to fall by gravity to the table in juxtapo 55
sition to the perforating mechanism E.
A yieldable holding member H is disposed op
positely to the lower end of the wall 3 so that the
cigar on the table is arranged between said wall
and said member, and as the wall 3 is moved to 60

The member II is pivoted on horizontal trun
nions l2 to swing away from the chute and is
normally swung toward the chute by a tension
10 spring l3 connected to a ?xed portion of the ma
chine and an operating arm l5 rigidly connected
to one trunnion i2 of the member.
As the holding member ii is forced away from

chute.
_
The means for actuating the member II and
20 the ejector I1 is shown as comprising a cam 20
mounted on a countershaft 2| which is driven
by a belt and pulley gearing 22 through a speed
reducing gear 23 from an electric motor 24. This
cam is followed by a slide rod 25 mounted on the
25 top of the table A and abutting a translating seg
- ment 26 pivoted at 21 on the table and abutting
the end 28 of another slide 25 mounted in guides
290 on the table. The slide 29 carries an actuat
ing rod 30 cooperating with the arm l5. The slide
30 28, translating segment 26 and slide 25 are nor
mally held in abutting contact and the slide 25
is caused to follow the cam 20, by tension spring
3|. The ejector I1 is connected to the slide 29.
With this construction, it will be observed that
35 periodically and simultaneously the ejector I‘!
will be moved transversely of the chute to push
the cigar from the table and the holding mem
ber will be swung out of the path of the cigar
to permit it to fall down the chute G. During this
40 action the ejector moves beneath the stack of
cigars in the chute, and upon retraction of the
ejector as shown in Figure 3, the lowermost cigar
.in the stack falls by gravity to the table.‘
One end of the cigar is perforated by the mech
45 anism E while the cigar is on the table. As shown,
the perforator mechanism is mounted at one end
of the chute C and includes a head 35 slidable
horizontally in guides 36 on the table and having
a socket 31 to embrace and hold‘one end of the
50 cigar. A perforating needle 38 is mounted to re
ciprocate in the head coaxially of the socket 31
into and out of the end of the cigar. For actu
ating the head I have shown a cam 39 on the
shaft 2| which engages an arm 40 depending from
.55 the head for moving the head toward the cigar,
the head-being actuated in the opposite direction
by a compression spring H and a push rod 42.
The needle 38 is actuated by a cam 43 on the shaft
2| arranged between the arms of a fork M on a
60 block 45 to which the needle is secured and which
is slidable in said guides 36. The cams 39 and 43
are of such shapes and in such timed relation
that the head 35 is moved into holding relation
to the cigar, after which the needle is moved into
65 and out of the cigar by the cam 43 while the cigar
is held by the head, whereupon the head is re
tracted from the cigar. The socket in the head
accurately locates or centers the cigar end rela
tive to the needle to ensure that the needle shall
70 penetrate the cigar at the proper point.
Of course, the operation of the head and nee
dle is in timed relation to the feeding of the
cigar, a cigar being deposited onto the table, while
the head 35 is retracted as shown in Figures 4
75 and 5.
chronously with the block. Accordingly, the wall
3 clamps the cigar approximately synchronously
with the movement of the needle into the cigar, 10
and holds the cigar until the needle is wholly
withdrawn, and jamming of the cigar against
the wall of the chute in such a way as to damage
operation is repeated on another cigar.
To accommodate cigars of different length and
accurately locate the cigars relatively to the
needle to ensure perforation to the proper depth, 20
and further provide yielding resistance to end
wise pressure exerted on the cigar by the head and
needle, a resilient abutment 60 is mounted on the
end wall of the chute opposite the needle and is
25
adjustable by a set screw 6|.
Another feature of my invention is the structure
of the perforating needle which is shown in de—
tail in Figures 8 and 9 of the drawings. As shown,
the needle includes a metal tube 50 having a solid
metal point 5i inserted in one end thereof, the 30
tube 50 being secured in the block 45. At the
inner end of and in direct heat exchanging rela
tion to and in contact with the metal point 5!
and within the tube 50 is arranged an electrical
heating unit 52 of generally known construc 35
tion. This heater is shown as comprising a core
53 of insulating material such as porcelain on
which is wound a coil 54 which may be embedded
in the core to prevent contact of the wires with
the metal tube. The heater is secured in the 40
tube by a plug 55 of suitable material such as
porcelain through which lead-in wires 56 for the
heater extend outwardly and through the tube to
an electric cable 51. The heater heats the pene
trating point 5| so as to facilitate penetration of 45
the cigar by the point.
The electric motor 24 and heater 52 may be
connected in circuit as desired, but preferably are
associated as shown in Figure 10; and preferably
a visible indicator such as an electric lamp is pro 50
vided in the circuit to indicate when the heateris
in proper operation. As shown in the ?gure, the
reference character L designates the line wires
and the motor is connected in parallel to the line
through a switch M. One terminal of an indicator 55
lamp N is connected to one line wire while the
other terminal is connected to one terminal of the
heater the other terminal of which is connected to
the other line wire. The circuit through the lamp
N and heater is controlled by the auxiliary switch 60
0. With this construction, the switch M controls
the circuit through the motor, and the switch 0
controls the heater and the lamp N. The motor
cannot be operated until the switch M is closed
and the heater is controlled by the switch 0 so
that the current will not ?ow through the heater
until said switch 0 is closed. When the switch
0 is closed and the circuit is intact, the lamp N
is illuminated but should the heater be burned
out or the circuit be otherwise disrupted the lamp
N will not be lighted, which will be a signal that
there is something wrong. Figure 4 shows the
switches M, O and the lamp N conveniently
mounted on the table A.

For agitating the cigars in the hopper D to
ensure 'their falling by gravity into the chute C,
I may provide an agitator plate 65 pivoted on a
shaft 66 which is connected through a crank arm
68 and a link rod 61 to the- slide 29, whereby the
plate is oscillated by and upon each reciproca
tion of the slide.
