further combination is used for sorts matrices
not stored in the magazine, so ‘that when auxil
20 iary magazines are used arranged alongside the
main magazine only 34 remaining combinations
are available for use in connection therewith.
The object of the present invention is to modify
the distributing mechanism, without any mate

order to extend the capacity of such auxiliary
or side magazines. To this end, the invention
contemplates a distributor bar having six pairs
of ribs of standard depth, the top pair‘ of ribs
30 of greater than standard depth, and matrices

section thereof at which the ?rst and second
ribs are missing, as shown in Figure 1, all of the 20
ribs of the bar being of equal depth.
Figure 2 shows a matrix B‘, also intended for
distribution into a main magazine, having a tooth
combination corresponding to that of the matrix
A, but modi?ed according to the invention by the
deepening of the recesses 2 beneath the top pair
of teeth 3, and cutting away a portion, indicated
in dotted lines in Figure 2, of the extra length
of the ?rst pair of teeth thus formed.
The matrix C, Figure 3, is formed according 30
to the invention, for distribution to an auxiliary
magazine, for which purpose the top pair of teeth
3a are of full length; in all other respects this
matrix is similar to the matrix B.

The invention is hereinafter more fully de

‘ drawing, in which :-'
Figure 1 is a side elevation of a matrix of
' ribs are cut back to the full depth as indicated at
l, at the parts where auxiliary-magazine matrices
such as C are to be released. ,
It will now be seen that as a matrix B is
traversed along the distributor bar section 4, by
a 2
one or other of its pairs of teeth engaging with
either the second pair of bar ribs of standard
form or with the uncut deep upper pair of ribs,
until it reaches the point indicated in Figure 2
and by the‘line 2—-2 in Figure 4, where one of
the cut-back portions 6 of the ribs 5 occurs in
the same vertical plane as a cut-back portion of
the second pair of ribs corresponding with the
standard second pair of teeth present in the tooth
10 combination. On the other hand, a matrix C
cannot be released from the bar section 4, as its
full length teeth 3‘1 will remain in engagement
with the ribs 5 at both the full-depth and half
depth portions thereof throughout the length of
15 the said section, and its release can take place
only at the correct rib combination on the auxil
iary magazine bar section 4*‘, where a full-depth
cut 1 of the upper ribs 5 occurs, as indicated in
Figure 3 and at the line 3—3 in Figure 4.
Thus, with the usual disposition of the 127
distributing combinations hereinbefore referred
to, the 45 tooth combinations employing the top
pair of teeth usually restricted to the main maga
zine may be duplicated, one set of the form of
25 the matrix B being allocated to the main maga
zine, and the other set of the form of the matrix
C being available also for the auxiliary magazine.
Further combinations embodying the top pair of
teeth normally allocated to the auxiliary maga
30 zine are retained for that magazine by giving the
top teeth the deeply recessed full-length form as
inpthe matrix C above described. The capacity
of the auxiliary magazine is thus increased by
forty-?ve matrix channels, without increasing
the number of teeth and ribs and without provid
ing special means such as heretofore proposed for
