New or Improved Means or Mechanism for Automatically Turning
over the Leaves of Books and the like.
I, THOMAS WALSH TETLEY, of 32, Havelock Square, Sheffield, in the County of
York, Publisher, 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:-
The object of this invention is to turn the leaves of books automatically, and the
apparatus is particularly adapted to books constructed somewhat similar to photo-
graphic albums, the pages of which may be mounted with printed matter and
illustrations suitable for advertising purposes; and consists in constructing mechanism
somewhat similar to that of a clock, which may be operated by a coiled spring or
other means; and combining therewith a rotating arm which acts on each revolution
on one of a series of balanced arms; each balanced arm being in connection with a
leaf of a book, and so mounted on cranks secured to a revolving shaft, that as the
shaft revolves, the balanced arms on one side the shaft are moved gradually towards
the centre of the same; and away from the shaft on the other side, so that the
revolving arm can operate each balanced arm and leaf consecutively, until all the
leaves have been turned over; or the leaves may be turned over by placing
the balanced arms on a fixed shaft and constructing the rotating arm so that a
projection on the same will be gradually moved towards, or away from the shaft until
all the leaves are turned over; then the motion of the revolving arm is reversed, and
the operation repeated.

The book to be operated upon is by preference prepared with thick paper, or card
board leaves, and is laid on the shelf A. of the case; the connection between the
mechanism, and leaves of the book being made through the semicircular opening A¹
through the front of the case A².
The frame B. carrying the mechanism, is secured to the base of case A² and the
shaft. C. is connected to the shaft D. by a train of gears E. motion being imparted to
the same by the uncoiling of the spring G. In connection with the shaft D. is
a "fly" F and gearing with the said shaft by bevel gears D' is vertical shaft F¹ which
revolves in one direction only, and is made to gear by the hevel wheel secured at
the top, with one or other of the bevel wheels G or G¹ and thereby to cause the
shaft H. to which they are attached to revolve first in one direction and then in the
other in the following manner.
'
On the shaft H. is fixed a worm J. gearing into wheel J. secured on a shaft on which
is a pinion J2 gearing into wheel K. to the shaft of which is attached an arm K¹
having a rod K2 connected thereto, in which is formed a slot hole through which passes
a stud attached to the end of the weighted lever L.
To the boss of this lever is secured a toothed quadrant M. in which gears a small
pinion N. mounted on the end of a lever or arm O. prepared with a boss near the
centre, through which the upper end of the vertical shaft F1 passes, and is supported
thereby the opposite end of the lever or arm at O being stayed by a pin, so that
by the rotation of the wheel K in either direction, the arm K¹ operates the rod K²
and thereby the weighted lever L and quadrant M; the latter gearing with small
pinion N. causes it to rotate and move the lever or arm O and upper end of shaft F1
such a distance that the bevel wheel at the top thereof, first gears with one bevel
wheel on the shaft H. and then with the other, so that by the wheels G and G¹ being
mounted one on each side of the shaft F1 the bevel wheel when in gear with wheel G
causes it to revolve in one direction, and when in gear with wheel G₁ on the opposite
side of shaft to revolve in the opposite direction, thereby rotating the shaft H. for a
certain time first in one direction and then in the other.
On the shaft H. is also secured a spur wheel P. gearing with the wheel P¹ through
an intermediate wheel, the wheel P¹ being on the shaft carrying the revolving arm Q.
and on the last mentioned shaft is a pinion R. gearing into a wheel R¹ on the shaft of
which is a pinion R³ gearing into wheel R₁ the latter being secured on the shaft S. on
which are also secured a series of cranks T. the cranks being of the same number as
the balanced arms U. and leaves in the book.
Each balanced arm U is mounted on a pin near the end of a crank T. and the
end of each balanced arm at U is prepared with a clip between which is placed
a leaf of the book; the opposite end of the arm having a weight W. for counter-
balancing.
On each revolution of the revolving arm Q. the end at Q' comes in contact with a
projection U¹ at right angles from the balanced arm, carrying it and the leaf placed
between the clip over from one side to the other. During the time the revolving
arm Q. is carrying a balanced arm U. from one side of the curved slot at X to X¹ see
Fig. 1. or vice-versa, the shaft S. and cranks T. are revolving slightly in the same
direction, and thereby carrying with them the balanced arms U such a distance, that
the projection U₁ of the balanced arm that is being carried over, is clear of the
end of the revolving arm at Q' by the time it has travelled from X to X' or vice-versa,
and the projection U on the next arm will have advanced so far. towards the centre of
the shaft S. that the end of the revolving arm at Q1 on its return to X. or X¹ as the

page_text: case may be, will come in contact with the same, carrying it and the leat over
rom X to X or vice-versa, the same operation being repeated until all have been
is reversed in the manner
carried over, when the motion of the rotating arm
before described; thus, by these means the balanced arins U. and book leaves
attached thereto are operated automatically, first in one direction, and then in the
other.
The balanced arms U and leaves in the book may be operated in both directions by
a modified arrangement shown by Fig. 12. which represents a plan view of such
portions of the apparatus hereinbefore described as are required to illustrate my
modification, and Fig. 13, is a sectional detail showing the means employed for
automatically adjusting the length of the revolving arm.
The book to be operated upon is laid on the shelf A. and the connections between
the respective balanced arms U. and leaves of the book are made as before described ;
but instead of securing the wheel P. on the shaft H. at the outside of frame B. as
before described and illustrated, I prefer to secure it to the said shaft on the opposite side
an intermediate
of the frame B. the spur wheel P. gearing with wheel P' through
wheel. the wheel P1 being secured on the end of a stud forming part of boss or
circular block 1. supported by the side frame B. to which is also secured a bevel
wheel 2. the hole through the centre of which forming part of the journal or bearing
for the before-mentioned stud..
To the boss or block 1. is secured a tube 3. in which is placed a bar 4. threaded for
some portion of its length near the boss or block 1. the remainder of the bar extending
to the outside of the tube being formed square, fitting a similar shaped hole formed in
the tube, and to the end of the said bar is attached a carrier 5.
To the opposite side of boss or block 1. in line with tube 3 is a short tube or
sleeve 6. so mounted, that it can rotate in its bearing in the said boss or block, and is
kept in its position by means of one or more screws 7. passing through the boss or
block 1. such a distance, that the ends project into annular grooves cut in the said
tube or sleeve, on which is secured a bevel wheel 8. gearing with fixed bevel wheel 2;
and in the interior of the said tube, or sleeve, is cut a thread, which engages with the
screwed portion of bar 4.
The balanced arms U. are mounted free to revolve on a fixed non-rotating shaft 9.
supported by suitable brackets, and each provided with a projecting bar 10 in addition
to the clip arm U' the length of the bars 10 varying in accordance with the position
of the balanced arm, all being arranged that the ends of the said bars are the same
distance from the rotating bar 4.
On the apparatus being put in motion, the boss, or block 1. is caused to rotate
manner as the
for a time in one direction, and then in the other, in the same
revolving arm; by which the bevel wheel S being in gear with the fixed bevel
wheel 2. is caused to rotate, and with it the internal threaded tube or sleeve 6 ; so
that during the rotation, the threaded bar 4. is gradually moving inwards or
outwards that the carrier 5 on each revolution will consecutively come in contact
with a
projecting bar 10. and carry it with the balanced arm attached thereto
from one side of the curved slot at X to X' or vice-versa; the threaded tube or
sleeve 6. at the same time rotating in its bearing causes the threaded bar 4. with
carrier 5 at the end to slide towards or from the centre of rotation at such a rate,
that on the carrier 5 lifting a balanced arm U. from one side of the apparatus to
the other, by the time the rotating carrier 5 has completed one half of a revolution,
the carrier will have moved so far towards, or from the centre of rotation as to
be clear of the projecting bar 10 just operated; and on completing the revolution
it will have moved such a distance as to come in contact with the next projecting
bar 10, carrying it and the book leaf from X to X or vice-versa; the same operation
being repeated until all the balanced arms U. have been carried over; when the
as herein before described ;
motion of the apparatus is reversed in the manner
thereby reversing the rotation of the boss or block 1. and attachments thereto, and
thus automatically operating the balanced arms U. and book leaves in connection
therewith first in one direction, and then in the other.

page_text: Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed 1 declare that what I
claim is :
1. The shaft S. combined with the series of cranks T. and corresponding balanced
arms U arranged substantially as described, whereby on the rotation of shaft S. the
respective projections U₁ are brought nearer and consecutively into the required
position on one side the shaft, and further away from the centre on the other, for the
purpose herein set forth.
2. The combination of the shaft S having a series of cranks T. thereon, with a
corresponding number of balanced arms U, and operating mechanism for the purpose
hereinbefore described.
3. The combination of a revolving threaded bar 4 with a series of balanced arms U
rotated first in one direction and then in the other substantially in the manner and for
the purpose as herein before set forth.
