COMPLETE SPECIFICATION.
Improved Machine for Necking Crackers and the like,
I, FERDINAND EMIL JAGENBERG, of 15B, Reichstrasse, Dusseldorf on the Rhine,
Germany, Merchant, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement:--
My said invention relates to an improved machine for necking crackers such
as Christmas crackers and similar tubular articles in which it is desired to form
necks or constrictions which are usually formed by the use of a cord or loop
drawn tightly around the article to be necked.
In order that my said invention may be more clearly understood I will describe
the same with reference to the accompanying sheet of drawings in which
Figure is a front elevation showing the apparatus open for the reception
of a cracker.
Figure 2 is a front elevation with a portion removed to show the arrange-
ment of the parts when the necking operation has been performed.
Figure 3 is a plan partly in section.
Figure 4 shows an ordinary Christmas cracker after necking.
In all the figures the same letters of reference indicate the same parts.
In a circular casing c¹ c² is an opening e e for the reception of the cracker.
The casing is preferably in halves c¹² so that the upper half may be turned
upwards on the joint pin 3 in order to facilitate the insertion of the crackers.
It might however be made as a single piece with a lateral slot for the admission
of the crackers.
To apply the constrictive pressure for producing the necks a number of
plates d are arranged in the casing. Each plate is fulcrumed on a pin d¹ and
is formed with a slot in which works a stud d secured to a divided disc g¹ g²
rotatably held in a recess of the casing by the screws f.
Each of the plates d forms a lever of the third order so that on the disc g¹ g²
being turned in the proper direction the inner ends of the plates converge towards
the centre as shown in Fig. 2 and form a neck in the cracker lying in the
opening e.
The machine is operated in the following manner-
A link which is connected with a pedal is connected to a swing plate h
aving its fulcrum at i. A closed cam slot 2 is formed in the swing plate to
eceive the roller on the projection from the upper half of the casing c².
On turning the swing plate h by means of the link k the casing is closed and
he roller then conies on the dwell of the cam.
wing plate brings the inner end h¹ to bear on the stud g of the disc g turning
A further turning of the
he latter and moving the plates d towards the cracker. If now the link k is raised
e hook h¹ first takes with it the stud g turning the disc g¹ g² backwards and
using the inner ends of the plates d to diverge. The hook h¹ then passes over
e stud g.and the cam slot 2 acting on the roller lifts the upper half of the
sing with the contained upper half of the disc g² and of the plates d.
By arranging two of these machines parallel to each other at a distamos

page_text: corresponding to the distance of the necks a b of Fig. 4 a single stroke of the
treadle enables both necks to be produced at once.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:―
1. A machine for necking crackers and the like substantially as set forth and
shown in the accompanying drawings.
2.A machine for necking crackers and the like consisting of a number of
plates or levers d grouped around a central aperture of a casing in combination
with a plate g g³ the rotation of which causes a simultaneous convergence of the
inner ends of the plates substantially as set forth and shown.
3. A machine for necking crackers having a divided casing the upper half
of which containing half of the necking plates and half of their operating disc
lifts substantially as and for the purpose set forth and shown.
machine for necking crackers in which the upper half of the casing
and the rotation of the disc which controls the necking plates is simultaneously
operated by the oscillation of a swing plate substantailly as set forth and shown.
Dated this 25th day of June 1899.
Dated his 20th day of June 1899.
