THOMAS WILLIAM DUFFY, of Liverpool, in the County of Lancaster. " IMPROVE-
MENTS IN APPARATUS FOR REGISTERING THE NUMBER OF PERSONS ENTERING AND
LEAVING CONVEYANCES OR PLACES OF PUBLIC RESORT, AND FOR CHECKING THE
RECEIPTS OF GUARDS OR OTHER OFFICIALS, AND FOR OTHER ANALOGOUS PURPOSES."
The said Invention relates to improvements in apparatus for registering the
number of persons entering and leaving conveyances or places of public resort, and
for checking the receipts of guards or other officials, and for other analogous purposes,
and has for its object so to construct the said apparatus that it is simple, compact,
and certain in its action, recording all entries and exits, and in the case of con-
veyances, the portions of the journey at which such entries and exits occur.
The apparatus constituting my said Invention consists as follows:-A main
spindle is actuated by the arrangement hereinafter described so that it receives a
motion of partial rotation on the exit or entry of a person, the said motion being
transmitted to two sets of rollers (each set consisting of two rollers) by means of a
worm or screw thread upon the said spindle, the said screw engaging with worm
wheels carrying pawls, which through ratchet wheels upon one of the spindles of one
of each set of rollers transmit the motion of the main spindle to the aforesaid rollera.
One set of rollers is to record entries, and the other set is to record exits (as herein-
after described) by the partial rotation of the main spindle in opposite directions.
One of the rollers of each set is preferably clothed with india rubber or equivalent
material, and the other is furnished with engraved devices or with projections which
may be plain or in the form of letters or other signs. Coils of paper or other
suitable material are supported above the rollers, and are fed to and between them,
one strip to one set to indicate entries, and the other strip to the other set to
indicate exits. The worm wheels are so arranged and each set of rollers is so
geared together that on the motion of the spindle in one direction, owing to the
entry of a person, the pawl in connection with the rollers of the set recording entries
as herein-before described causes the partial rotation of the said rollers, so that the

page_text: strip passing between the said rollers is marked with one of the type or indicating
marks upon one of the said rollers, the strip by the said motion being caused to
travel between the said rollers; the pawl in connection with the other set, recording
exits, riding over the ratchet wheel of that set without transmitting motion thereto.
The reverse action takes place on the exit of a person so that every entry is marked
on one strip of paper, and every exit upon the other. In order to indicate at what
time or portion of the journey the several entries and exits occur the two paper
slips are led through perforated guides, through the perforations in which guides
serics of perforating needles may be forced at each division of time or station of the
journey, so as to pass through both strips of paper, so that all markings upon the
strips between any two perforations will be a record of the entries and exits between
the two particular times or points in the journey at which these perforations were
made.
In connection with the perforating mechanism is an arrangement of type-wheel
for marking upon the strips by perforation, embossing, or otherwise to indicate at
what time or period of the journey each perforation was made, the said wheel being
formed with ratchet teeth actuated by a pawl at each stroke of the perforating
needles, so as to bring a fresh type into position for marking. A pad, or pads, or. a
die, or dies, is or are operated through levers actuated by the moving part of the
perforating apparatus so as to be brought forward to meet the type, it or they being
returned clear of the passing strips when the marking is effected. The main spindle
and gear for driving the indicating rollers may be on the outside of the framing of
the apparatus. The projections or markings of the indicating rollers may act to
emboss or to print with ink or other printing medium. In the latter case small ink
feeding rollers will be arranged in contact with the said indicating rollers, the said
feeding rollers revolving in troughs containing ink and transferring the ink to the
rollers or by other suitable arrangement.
In order to render the apparatus certain in its action, that is to say, to ensure
the recording of the entry and exit of every person the main spindle is provided
with the following arrangement:-The said arrangement consists of a number of
projecting arms or wings, cach wing being connected to the main spindle, so that
when each or either of the said arms or wings is moved in a horizontal direction it
compels the partial rotation of the main spindle and the necessary actuation of the
apparatus to record an entry or exit. The apparatus may be placed in the side or
post of the door of the vehicle or other entry, one of the arms or wings projecting before
the entry and necessitating its being turned through a portion of a revolution before
a person can enter or leave. In order that the arms or wings which are not before
the doorway or entry may not project the following arrangement is provided:-The
arms or wings being pivoted as aforesaid to the spindle incline to fall, but that one of
the said arms or wings which is before the doorway or entry is supported upon an
inclined or cam-like piece. When this arm or wing is by the entry or exit of a
person moved from before the opening, the said arm or wing will descend the incline
of the inclined piece, and will be folded up so as to lie parallel or nearly so with the
spindle, another of the arms being caused by the same movement to rise up the
inclined piece and project before the doorway or entry. The arms or wings may
each consist of one arm or they may each consist of more than one arm projecting
immediately under each other, each arm being pivoted as aforesaid to the main
spindle and acted upon by inclines which may be both above and below the said
wings. If the arms of each wing are connected together at their outer ends, the
piece connecting them must be hinged thereto so as not to interfere with the
folding of the arms. The motions of the main spindle may be controlled and facili-
tated by means of a squared or equivalently formed part upon it, upon opposite sides
of which strong springs bear to tend to retain the spindle in the position to which
it is brought with a wing or arm before the entry, the corners of the squared part
being provided with antifriction rollers to facilitate the turning of the spindle when
the arms or wings are operated.
The distances travelled may be recorded by an indicating dial or dials, the me-

page_text: chanism of which may be operated by the movements of the perforator, so that if
the perforator be not worked at the proper time the indicator of the dial will be in
a wrong position and indicate the omission.
The apparatus may be protected from being tampered with by being enclosed in
a locked case into which the main spindle passes, the perforating apparatus being
operated by a stud projecting from it to outside the said case. The strips of paper
can at intervals be removed from the locked case and examined to ascertain the
amount of fares which the guard or other official has received.
It will be evident that the apparatus is applicable to recording entries and exits
generally.
