COMPLETE SPECIFICATION,
Counting and Controlling Apparatus for Book Binders' Wire
Stitching Machines.
I, THEODOR PAUL KÄMMERER of Koch Strasse 68 Berlin, in the German
Empire, Master Bookbinder, 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
:―
In mechanically binding journals pamphlets, books and the like the journals,
pamphlets or sheets coming from the wire stitching machine have to be counted.
into packets of 10, 20 or more copies according to their thickness before they are
brought to the cutting machine in order to prevent this machine from being over-
loaded. This counting of the journals or books and dividing them into packets
takes time and no reliable control of the sheets supplied by the printer is exercised
as during the very tedious work of counting, mistakes are very easily made. These
inconveniences are obviated by my invention which consists in an improved
construction of counting and controlling apparatus and combination of the same
with the wire stitching machine which apparatus is so arranged that not only are
the wired journals or sheets consecutively counted but their collection in the
required quantities is indicated by a stroke on a bell so that when the bell has
sounded, it is only necessary to place the following sheets crosswise to the preceeding
ones till the bell sounds again and so on. In order to make the counting
apparatus applicable to wire stitching machines, which work with sudden motion
and shocks, special arrangements are provided for obtaining a quiet and certain
:

page_text: a bell Fig. 1, so that a signal is given each time that 25 sheets have been
wired.
The pusher m receives its motion from the bellorauk lever B Fig. 3 which is
actuated by the grooved cam C, and operates with its forked end the clinching bar
of the machine. The cam C has a circular groove which at passes into a
quickly ascending and descending curve. The lever B enters with the peg bl
into.this groove and oscillates on the axis 6. The pusher receives in consequence
of the quick curve a sudden intermittent motion from the lever B and carries
for adjustment and limiting its stroke two set-hoops m m. Upon the base plate of
the frame A a swivels Figs. 1 & 2 is arranged near to the pusher m which can be
turned and brought under the set-hoop ml on the pusher m whereby the latter is put
out of action. In order that the sudden jerky motion of the pusher m, belloranki,
and pawl n may not cause any teeth to be missed or an irregular advance of the
ratchet wheel the brake pulley is fixed on shaft and surrounded by a brake-
band tightened by the weighted lever u. The latter swivels on the stud v
screwed into bracket fixed on the base of frame A. Fig. 3. A spring to is
attached to the limb of the bellcrank carrying the pusher m and to the base
plate which returns the pusher m into its starting position after it has been
raised by the lever B. The apparatus operates as follows: At each revolution
of the cam C the lever B makes an oscillation and clinches the wires of a sheet and
at the same time the pusher m is lifted and moves the bellcrank i so that the pawl n
advances the ratohet. wheel k by a tooth, the pegs o in this wheel advancing towards
the hammer lever q. Each peg in turn depresses the lever and extends the spring pl
so that when the lever q is released by the peg the hammer g' strikes the bell r. In
the arrangement shown the indication of packets of 25 sheets or pieces is provided
for. If the number is to be varied an arrangement similar to that shown by
Figs. 5 & 6 is conveniently used. The pegs o are arranged in a circular groove o
of the ratchet and fixed in any desired position by screws o². The ratchet wheel is
in this case provided with a graduated scale. In this way any subdivisions of the
number of teeth of the ratchet can be indicated, for instance with a ratchet of
100 teeth, 5, 10, 20, 25, and 50. If other numbers are desired ratchet wheels with
a different number of teeth can be used; with 144 teeth packets of 1, 2,3,4
and 6 dozen can be indicated, with 240 teeth quires and multiples of quires can be
indicated.
The motion of the ratchet wheel k is transferred to the other shaft of the
counter by the wheels 2 2¹ 2 or in any other manner usually employed for this
purpose in counters.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :
1. The arrangement or construction of counting and controlling apparatus for
wire stitching machines substantially as herein before described and illustrated.
2. In counting and controlling apparatus for wire stitching machines operated
by a pawl, lever and ratchet wheel acting suddenly the arrangement of a brake for
preventing the overrunning of the ratchet wheel substantially as herein described
and illustrated.
3. The combination with a continuously acting apparatus for wire stitching
machines of a signalling apparatus for indicating the completion of a predetermined
number of sheets substantially as described and illustrated.
