the County of Middlesex, for the Invention of "IMPROVEMENTS IN PRINTING
MACHINERY," A communication from abroad by Hippolyte Marinoni; of Paris,
France.
Sealed the 29th August 1879, and dated the 3rd July 1879.
COMPLETE SPECIFICATION filed by. the said Albert Sauvée at the Office of
the Commissioners of Patents on the 3rd July 1879.
ALBERT SAUVÉE, of 22, Parliament Street, Westminster, in the County of Middle-
sex: "IMPROVEMENTS IN PRINTING MACHINERY." A communication from abroad
by Hippolyte Marinoni, of Paris, France.
This Invention relates to that class of printing machines known as perfecting
machines, in which a sett-off sheet is used in connection with the sheet to be
printed.
The main object of this Invention relates to a novel arrangement or combination
and construction of parts for separating the sett-off sheet from the newly printed
sheet, cutting in two or more parts as required the printed sheets alone, and
delivering the printed and sett-off sheets separately on delivery tables by means of
a double flyer.
This arrangement will be understood by referring to the Drawing, Fig. 1, Sheet I.,
in which D is the first impression cylinder and D₁ the second impression cylinder.
The sheet, which is fed from the board E, is printed on one side, and when it is
delivered by the grippers of the D cylinder to those of the D' or perfecting cylinder
it meets in O the leading edge of the sett-off sheet which has been fed from the sett-
off board E'.
->
It will be seen by the diagram that there are three distinct sets of tapes. The sett-
off sheet is caught and carried away by the tapes No. 1 and tapes No. 2. The tapes
No. 3 support the printed sheet which is carried away.between the tapes No. 1 &
No. 3. The printed sheet and the sett-off sheet will travel together in the direction
of the arrow up to the roller a.
F and F are the arms of the double flyer. F delivers the printed sheet on the.
board B, and F the sett-off sheets on the board B¹.

At the point a the three sets of tapes which have been travelling together take
various directions. The tapes No. 3 and half of the tapes No. 1 travel together to
the point b on the-female-cutting-roller C, and keep the sheet tight on the roller.
N is a small rotary knife that divides the printed sheet as it passes over roller C.
on its way.down-along the flyer F The other half of the tapes No.. 1, and the set
of tapes No. 2 go over the small roller a and over the small rollers & and d, & deliver
_the-sett-off sheet along the flyer F
The sets of tapes No. 4 & No. 5 are merely helping_tapes._
The mode of working the double flyer is as follows:-
K is a cam mounted on a shaft making one revolution per sheet; it works the
-rod P, which is connected to a hell-crank; this-crank works the double rack R in
gear with the two small pinions p & p' fixed on the axis of each arm of the double
flyer. By referring to the diagram, Fig. 1, it will be seen that the two arms of the
flyer beat in opposite directions.
Having now set forth the nature of this Invention of improvements in printing
machinery, communicated to me by my foreign correspondent, and having explained
the manner of carrying the same into effect, I claim the following points:-
First. The novel arrangement of a double flyer by which the sett-off and the printed
sheet are "flown" in opposite directions and deposited on receiving boards at the
same time by means of a single cam (or any other mechanism), as herein set forth
and represented in accompanying Drawing.
Second. The arrangement of the tapes in connection with the cutting knife so
as to use half.or a portion of the same set for carrying the sheet under the knife or
knives, and the other half or portion of the set to carry off the sett-off sheet.
Third. The delivery of the printed sheet on the receiving board on the same side
as it comes out usually when the sheet is received by hand.
Fourth. Although I prefer the arrangement of the double flyer worked by one
cam only, I also claim the disposition of two vertical, or nearly so, flyers standing
back to back and flying the sheets in opposite directions, but worked each one
separately by an independent mechanism.
In witness whereof, I, the said Albert Sauvée, have hereunto set my hand
and seal, this Third day of July, in the year of our Lord One thousand
eight hundred and seventy nine.
A. SAUVEE.
