Engineer, for the Invention of "IMPROVEMENTS IN MACHINERY FOR DELIVERING
AND COUNTING PRINTED SHEETS OF PAPER."
Sealed the 15th August 1876, and dated the 29th June 1876.
PROVISIONAL SPECIFICATION left by the said James Farmer at the Office
of the Commissioners of Patents on the 29th June 1876.
" IMPROVE-
JAMES FARMER, of Salford, in the County of Lancaster, Engineer.
MENTS IN MACHINERY FOR DELIVERING AND COUNTING PRINTED SHEETS OF
PAPER."
My Invention is particularly applicable for delivering and counting newspapers
as they are printed on any rotary printing machine.
My improved machinery consists of a rotary drum provided with flyers revolving
with the drum. These flyers are depressed in succession at the delivery point by a
fixed cam, and deposit the paper which has been brought forward by tapes and
secured to the drum by grippers on to an endless band or tapes passing around
rollers. The grippers are released and again brought into position by adjustable
slides or cams connected to the framework.
After the required number of printed sheets of paper has been delivered on to
the endless band or tapes motion is communicated to the band or tapes by friction,
or by a star wheel or other equivalents, to discharge the accumulated printed
sheets.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said James Farmer in the Great Seal Patent Office on the 29th December

as they are printed on any rotary printing machine.
My improved machinery consists of a rotary drum provided with flyers revolving
with the drum. These flyers are depressed in succession at the delivery point by a
fixed cam, and deposit the paper which has been brought forward by tapes and
secured to the drum by grippers on to an endless band or tapes passing around
rollers. The grippers are released and again brought into position by adjustable
slides or cams connected to the framework.
After the required number of printed sheets of paper has been delivered on to
the endless band or tapes motion is communicated to the band or tapes by friction,
or by a star wheel or other equivalents, to discharge the accumulated printed
sheets,
And in order that my Invention may be fully understood and readily carried
into operation I will proceed to describe the accompanying Sheet of Drawings,
reference being had to the letters and figures marked thereon.
Fig. 1 is an elevation of my improved machinery for delivering and counting
printed sheets of paper with part of a rotary printing machine in position; Fig. 2
is a plan of the same.
Figs. 3 and 4 are detached views drawn to an enlarged scale of part of the
improved machinery.
In Fig. 1 a, a, are the cutting rollers forming part of an ordinary rotary printing
machine for newspapers, and b, b, are tape rollers for the tapes c, c, passing around
the rollers d, d; the tapes c, c, deliver the sheets as they leave the printing machine
to the tapes e, e, passing around the rollers f, f, and g, g.
The sheets of paper are delivered by the rollers g, g, to the roller h, which is
pressed against the surface of the rotary drum i by the weighted lever h¹, this
roller is provided with annular grooves to allow the grippers to close. The drum i
is divided longitudinally into 15 or other convenient number of spaces, between
which are the 14 or other convenient number of arms forming one flyer; 4 flyers
are shewn in the circumference of the drum, but I do not confine myself to any
number; these flyers revolve with the drum, which revolves in bearings fixed to
the side frames. To the inside of each side frame is fixed the cams k, k, the grooves
of which are concentric to the drum, excepting at the part k¹, which is the depressing
point. The flyers j are connected to the cams k by the slides and cross piece,
and each cross piece supports an antifriction bowl fitting in the grooves of the
cams k, k. To the inside of the drum are fixed the brackets & supporting the axles
of the grippers 7, shewn detached in Figs. 3 and 4, and these grippers are closed
to catch hold of the end of the sheet of paper which has been brought forward by
the tapes e and rollers g, and again opened to release the same in the following
manner: To each axle is fixed a spur pinion 13 gearing into a segment wheel *,
which is mounted on a stud fixed in the bracket, and in each wheel is a boss
carrying an antifriction bowl 18; these bosses are connected by the bent arms 1 to
the springs fixed to the inside of the drum i. As the drum revolves in the
direction of the arrow in Fig. 1 the bowl 5 enters the groove of the fixed cam m
and in passing down the groove the grippers 1, which had previously been open, as
shewn by the full lines in Fig. 3, are closed on to the edge of the sheet of paper, as
shewn by the dotted lines in Fig. 3.
When the drum in continuing its rotation brings the bowl 15 into the groove of
the second fixed cam n the grippers are again opened to release the sheet of paper.
The cams m and n are adjustable to regulate the moment at which the paper is
caught hold of and released.
It will be seen that the grippers are held in the two positions by means of the
spring and bent arm le; the pin on the wheel to which the bent arm is attached
is placed in such a position that in opening it passes beyond the line of centre in
the said wheel on one side and in closing passes the line of centre on the other side,
thus bringing the spring into action to hold the gripper open and also closing it
tighter on the paper. As soon as the paper is released by the opening of the

page_text: grippers the bowls
connected to the bottom flyerj enter the delivery points k¹ of
the cams k, and the bottom flyer deposits the sheet of paper on the endless band or
tapes o which pass around the driving roller p, the guide roller q, and the inter-
mediate rollers r. The roller mounted on a weighted lever is to keep the band
or tapes to the proper tension. An intermittent motion is given to the band or
tapes o, as will be explained hereafter.
The requisite motion is transmitted to the various parts of the machine in the
following manner :-The shaft 8 is driven from any convenient part of the ordinary
printing machine or from the engine by which it is driven, the bevel pinion 8¹ at
the end of the shaft s gears into the wheel i fixed to the axle of the rotary drum i,
and the mitre pinion 8%, also fixed on the shaft 8, gears into a similar pinion 2 on
the short shaft t, on which is the spur wheel t¹ gearing into a broad carrier pinion
which drives the pinion g' on the axle of the upper roller g. The bevel wheel 2¹
drives the pinion u¹ on the diagonal shaft u, and on this shaft is fixed the worm u³
and the mitre pinion u³ gearing into the wheel pl fixed to the friction box p³, both
of which are loose on the axle of the roller p, but connected to it when required
by the friction cone p³, which moves on a fixed key in the axle. The worm u
gears into the worm wheel 2 on the shaft v, to which is fixed the disc cam v¹, the
recess in which acts on a bowl at the end of the clip lever ³, which takes into a
groove in the sliding friction cone ps; by this means at every revolution of the disc
cam v¹ the sliding friction cone p³ is brought into gear with the friction box p³, and
when in gear the band or tapes o are put in motion. As soon as the recess in the
disc cam v¹ comes opposite the end of the clip lever ³ the friction cones are brought
instantly into gear by a weighted lever or spring.
Instead of the friction motion above described the roller p may be driven by
intermittent wheels or other equivalents.
The mode of operation is as follows:-As the drum i revolves the flyers deposit
the sheets of printed paper on to the band or tapes o until 12 or other convenient
number of sheets have accumulated thereon, such number being determined by the
worm us and wheel 2; the recess in the disc cam then brings the friction cone p³
into gear with p³, to connect the wheel p¹ to the axle of the roller p, which is then
put into motion to discharge the accumulated printed sheets on to the table w, the
friction boxes are then instantly disconnected by the cam ¹ to stop the roller p
before the next sheet is deposited on the band or tapes o, and when the required
number of sheets has accumulated thereon they are again discharged in the manner
described.
Having thus stated the nature of my Invention, and described the manner of
performing the same, I declare that I claim,-
First. The improved machinery shewn and described for delivering and counting
printed sheets of paper.
And, Secondly. The rotary flyers marked j, which may be actuated in the manner
described, or in any other convenient manner.
In witness whereof, I, the said James Farmer, have hereto set my hand and
seal, this Twenty-seventh day of December, One thousand eight hundred
and seventy-six.
