COMPLETE SPECIFICATION.
Pamphlet or Book Covering Machine.
We, BENNETT SPERRY LEWIS, Physician, 1093 Chapel Street, and ANDREW
HENRY SMITH, Manufacturer, 67 Dwight Street, both of New Haven, Connecticut,
United States of America, 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 :-
Our invention has for its object to provide a machine for attaching paper covers
to books which shall be capable of adjustment to adapt it to all sizes and styles of
books and which shall be perfectly automatic in operation.
With these ends in view we have devised the novel machine of which the

page_text: Fig. 20 an inverted plan view of the book carrying chains and the frames therefor
detached.
Figs. 21 and 22 are respectively an enlarged plan view and a side elevation
illustrating the construction of the book carrying chains, and
Figs. 23 and 24 are sections on an enlarged scale on the line n―n in Figs. 8
and 10, Fig. 23 showing the position of the friction wheel and shoes while the
standard, frame, platform, table &c. are moving downward, the friction wheel being
held against backward movement by one of the shoes, the other shoe being
inoperative, and said fig. also showing in dotted lines the position of the parts at
the beginning of the downward movement so as to illustrate in connection with
Figs. 9 and 25 the manner in which the standard is raised slightly relatively to the
slide in the case during each downward movement; and Fig. 24 showing a position
of the friction wheel and shoes while the standard, frame, platform, table &c., are
moving upward the shoe which held the friction wheel against backward movement
during the downward movement of the parts now slipping over the surface of the
friction wheel, but the other shoe holding the friction wheel against backward
movement; and Fig. 25 is a view showing the position of the parts when the
standard, frame, platform, table &c., have reached the extreme of the upward
movement and the downward movement is about to commence, this fig. in connection
with Figs. 9 and 23 illustrating the manner in which the friction wheel is caused
to move forward slightly during each downward movement of the standard, frame,
platform table &c., so that the table is held back sufficiently at each downward
movement, or more correctly is raised relatively to the other parts to compensate
for the thickness of the cover removed while the table was at the raised position.
It should be noted that Figs. 1 to 14 inclusive and Figs. 16 to 22 inclusive all
show the parts in the same position, that is a position in which the table is at the
lowered position and at the extreme of its movement toward the front, the upward
movement being about to commence. In Figs. 1 and 3 the lowered position of the
table at the other extreme of its longitudinal movement is indicated by dotted lines.
In Fig. 15 the table is shown at the extreme of its upward movement, another
longitudinal movement of the table and platform wholly independent of any
movement of the standard and frame, being indicated by a dotted position of the
parts. The position of parts in Fig. 23 is substantially the same as in Figs. 9
and 14, the space between the inoperative shoe and the friction wheel being greatly
exaggerated so as to indicate clearly the position the parts occupy during the
downward movement. It should be noted furthermore that wherever the terms
rear and front are used they refer respectively to the feeding end and to the
delivering end of the machine. But a single operator is required to run the
machine. This operator stands at the front or feeding end of the machine, that is
the left as seen in Figs. 1 and 2 and the right as seen in Fig. 3.
1 denotes framework which may be of any ordinary or preferred construction
and 2 the main shaft journaled therein. Power is applied to drive the machine by
a belt, not shown, running over a belt pulley 3 which is rigidly secured to shaft 2.
This shaft also bas rigidly secured to it a sprocket wheel 4 and a collar 5 in which
a clutch lever 6 is pivoted, see Fig. 19. 7 denotes a sleeve which is journaled on
the main shaft and has rigidly secured thereto a pinion 8 and is provided with a
head 9 which lies in a socket 10 in collar 5. 11 denotes a cone on shaft 2 which
is secured thereto by means of a rib 12 but is free to slide longitudinally thereon.
This cone is controlled by a yoke 13. The yoke partially incloses the cone in
the usual manner leaving the latter free to rotate within the arms of the yoke.
This yoke has formed integral with it or rigidly secured thereto an
provided with a sleeve 15 which is free to slide on a shaft 16 above the driving
shaft. 17 denotes a link one end of which is connected to arm 14 the other being
pivoted to a hand lever 18 which is itself pivoted between lugs 19 extending from
any suitable portion of the framework, see Figs. 2 and 7. It is obvious that
movement of the cone toward the left as it appears in Fig. 19 will force the end of
clutch lever 6 that is in engagement therewith outward. It will be noticed
arm 14

page_text: in Fig. 19 that the other end of clutch lever 6 extends inward as at 20
SO as to engage head 9 on sleeve 7. When the cone is moved toward the
left therefore as it appears in Fig. 19 the clutch lever is caused to
engage head 9 with a frictional contact and communicate the motion of shaft 2
to sleeve 7. Pinion 8 on this sleeve meshes with two gears 21 and 22 carried
respectively by shafts 23 and 24, see Fig. 19 in connection with Fig. 8. These
shafts are journaled below the main portion of the framework as indicated in Figs. 1
and 3. 25 denotes a hand wheel on shaft 16 by which the machine may be operated
should it be desired to move the parts without application of power. Shaft 23
carries a bevel gear 26 and two cams designated respectively as 27 and 28.
Cam 27 by means of intermediate connections presently to be described in full
imparts longitudinal reciprocatory movement to the cover carrying table; cam 28
by means of intermediate connections presently to be described imparts longitudinal
reciprocatory movement to the cover setting slide which carries a roller that
presses the cover against the back of the book. This cover setting slide also
serves as an ejector as will be explained. Shaft 24 carries a series of cams
designated respectively as 29, 30, 31, 32, 33, 34, 35. These cams are numbered in
regular order on the shaft as they appear in Fig. 8 without regard to the order
in which their operation will be described. Cam 29, see Figs. 1 and 2, operates a
pusher which moves the books forward a short distance, after it has passed the
carrying chains and into position to be operated upon by a pusher which moves
the book down into position to be operated upon by the cover setting roller
and at the same time folding the cover to the sides of the book; cam 30 operates
a pusher which forces the book between the carrying chains; cam 31 operates the
pusher which places the book in position to be operated upon by the cover setting
roller and folds the cover to the sides; cam 32 by means of intermediate connecting
mechanism presently to be described raises the cover setting table; cam 33 acts
to raise the stop which holds the covers upon the cover carrying table; cam 34
operates the table which supports the book for an instant after it passes from the
chains and also operates the squeezer plate which holds the book while the cover is
heing set to the back of the book by the cover setting roller and cam 35 operates
a pusher which moves the covered books out of the way after they have been
ejected and presses them forward on the book receiving table. Turning now to
Figs. 1, 2, 3, and 6, 36 denotes a table at the front of the machine upon which
the books to be covered are placed (so far as my present invention is concerned the
books which we have indicated by D, may be fed in any ordinary or preferred
manner) and 37 a vertical plate rigidly bolted to the table against which the side
of the book to be immediately operated upon rests, the back of the book resting
upon the table. Upon the outer side of plate 37, see Figs. 1 and 2, are brackets 38
in which a rod 39 reciprocates. This rod carries a block 40 which is adjustably
secured thereto by means of a set screw 41 or in any suitable manner.
block carries the pusher 42 which may be a sliding plate if preferred although in
the present instance we have shown two rods which pass through slots 43 in
plate 37 and act to push the books forward. The rod, block and pusher are
reciprocated by means of cam 30 in connection with a rod 44 one end of which is
pivoted to rod 39 the other being pivoted to a lever 45 journaled on a cross rod 46
which extends between portions of the framework. This lever carries a roller 47,
see Fig. 8 also dotted lines Fig. 3, which engages a groove in the inner face of
cam 30, so that each rotation of the main shaft and cam 30 will produce a forward
and backward movement of the pusher and will force a book between the carrying
chains, the construction and operation of which we will now describe. Turning
now to Fig. 8 in connection with Figs. 2, 6 and 20, 48 denotes a bevel gear carried
by a vertical shaft 49 and meshing with bevel gear 26 on shaft 23. At the
upper end of shaft 49 which is made in two parts as will presently be explained is
a pinion 50 which meshes with an idler pinion 51 which in turn meshes with a
second idler pinion 52 the latter meshing with a pinion 53 carried by a short
shaft 54. Shaft 49 passes through a cross piece 95 of the framework, by which it
This

page_text: is supported, and the upper ends of shafts 49 and 54 are both jourualed in hubs 96
which extend above the chain carrying frames. 97 denotes bolts which pass
through washers 98 and engage the ends of the shafts thereby retaining them in
place. A, denotes the fixed and B, the movable chain carrying frames. These
frames each consist essentially of an upper plate 55, a lower plate 56 a web 61 by
which the upper and lower plates are connected and a vertical plate 226, the
two vertical plates acting to support the sides of the books as they are carried
along by the chains. The upper end of shaft 49 passes through the fixed frame in
which it is journaled and shaft 54 is journaled in and is carried by the movable
frame. Idler pinions 51 and 52 are carried by a swinging arm 57 one end of which
is pivoted on shaft 49. Idler pinion 51 is journaled on a stud 58 extending from
said arm, and idler pinion 52 is journaled on a stud 59 which extends from said
arm, passes through a slot 60 in the lower plate of chain carrying frame B and is
held in position by a nut 62 which bears upon the plate, see Fig. 2. On the
opposite end of the belt carrying frames are studs 63 upon which are journaled
pocket wheels 64. These studs are held in place by nuts 99 which bear upon
other hubs 96 which extend above the top plates 55 of the chain carrying frames.
Shafts 49 and 54 both carry sprocket wheels 65 one of which is clearly shown in
Fig. 3 in which view the chain is removed. We have not deemed it necessary to
illustrate these sprocket wheels more in detail for the reason that they are identical
with sprocket wheels 64 except that they are fastened to and are carried by the
shafts and act to drive the book "carrying chains while sprocket wheels 64 are
idlers and merely carry the chains. C denotes the book carrying chains each of
which is continuous and the construction of which is shown in detail in Figs. 21
and 22. These chains consist essentially of outer links 65' the ends of which are
pivoted together as at 66 and which carry studs 67 upon which rollers 68 are
journaled, and between said outer links intermediate links 69 which are separated
by blocks 70, pivots 66 passing through the intermediate links and through the blocks
as well as through the outer links. The intermediate links are suitably curved to
receive the rollers as clearly shown in dotted lines in Fig. 21. This construction
provides a very strong chain which will not stretch to any serious extent in use. It
will be understood from Figs. 2 and 6 in connection with Fig. 20 that the action
of pinions 50, 51, 52 and 53 and the sprocket wheels is to carry the chains forward
in opposite directions, the movement of both chains being inward so that the inner
sides of the two chains will move parallel and in the same direction. The books
which we have indicated by D as they are carried forward are clamped between the
backs of the outer links of the two chains, the position of the books as they are
carried forward will be clearly understood from Fig. 2. When the machine is in use
the rollers travel upon the webs 61 of the chain carrying frames as is clearly shown
in Fig. 20 in which one of the lower plates is broken away. In order that the central
portion of the chain carrying frames may be made as narrow and consequently as light
as possible, consistent with strength, and in order furthermore to take up any
stretch in the chains that may occur from use we provide adjustable plates or
shoes 71, see Fig. 20, which are adapted to be moved inward against the backs of
the chains so that in use the rollers on the outer sides of the chains, that is the
portions of the chains not in use, will also travel upon the webs as is clearly shown
in Fig. 20. Plates 71 are carried by headed studs 72 which are adapted to move
in or out in slots 73 in the upper and lower plates of frames A and B, see Figs. 1
and 20, the studs being locked in position after adjustment by nuts 74. It will be
noticed in Fig. 20, which is a plan view, that plates 56 of the chain carrying
frames are not made the full length of the chains. In practice, we incluse sprocket
wheels 64, on the under side, by independent plates 75 which are secured to
suitable ledges 76 cast integral with the frames. This construction is simply for
convenience in assembling, plates 75 being shown only in Figs. 1 and 20. One
end of frame A, the right end as seen in Fig. 1, rests upon a bracket 77 upon a
casting 78 to which it is rigidly bolted, see Fig. 1 in connection with Fig. 4,
casting 78 itself being bolted to the framework. The other end of frame A rests

page_text: upon table 36 to which it is likewise bolted. The right end of frame B, as seen in
Fig. 2, rests in suitable ways 79 in which it may slide freely for the purpose of
adjustment. 80 is a bracket extending from casting 78 which carries an adjusting
screw 81, said screw being held against longitudinal movement in the bracket and
the inner end thereof engaging a stump 82 on frame B. The other end of frame B,.
the left as seen in Fig. 2, rests upon table 36 upon which it may slide for the
purpose of adjustment. Upon the under side of this frame, see Fig. 20, is a
stump 83 which is engaged by an adjusting screw 84, similar to screw 81, see-
Fig. 2, which is itself carried by a bracket 85 extending from any suitable portion
of the framework. It will be understood from Fig. 2 that stump 82 which is.
engaged by one of the adjusting screws is upon the upper plate of frame B and
that stump 83 which is engaged by the other adjusting screw is upon the lower
plate of frame B. It will of course be understood that rotation of these adjusting
screws will move from B toward or from frame A, this adjustment being necessary
when books of a different thickness from those previously acted upon are to be
covered. Both of these screws are provided with hand wheels 86 for convenience
in manipulation. 87, see Fig. 20, is a hand screw engaging lugs SS on the under
sides of frames A and B, said hand screw being threaded to engage one of the lugs
but rotating freely in the other lug without engagement therewith.
The object
of this hand screw is to lock the two frames to each other to prevent the possibility
of the frames springing when subjected to the severe strain of use, it being under-
stood that the books are clamped very firmly by the links of the chains and that
there is of course a tendency to spring the frames ontward from each other. This
is wholly overcome however, by the use of hand screw 87 which must of course be
operated when frame B is adjusted by means of screws 81 and 84. It will be
apparent from Fig. 20 in connection with Figs. 1 and 2 that the chain carrying
frames and with them the sprocket wheels and the driving gears may be readily
detached from the framework. In order to provide for the convenient removal of
the chain carrying frames we make shaft 49 in two parts which may be connected
by any suitable slip joint as for instance as indicated at the left in Fig. 20 in which
the lower end of the upper portion of shaft 49 is shown, said portion of the shaft
heing provided with a transverse groove 90 which is adapted to receive a corre-
sponding tongue formed at the upper end of the lower portion of said shaft, said
lower portion not being shown in the drawing, as the special mode in which the
joint is formed is not of the essence of our invention. As the books are carried
along by the chains the backs being downward the back of each book passes over
a glue roller 91, the under side of which lies in a glue tank 92. This tank is
provided with an outer jacket 93, the jacket being filled with water which surrounds
the tank and is kept heated to a high temperature to keep the glue in liquid form
by means of steam admitted through a pipe 94, and with a cover 100 having
slot 101 through which the glue roller passes. 102 denotes wiper plates which are
adjustably secured to a plate 103 which is formed integral with or rigidly secured
to a lever 104, the latter being pivoted in Ings 105 on a plate 106 rigidly secured
to the under side of plate 56 of belt carrying frame A, see Figs. 3, 6 and 20 the
lugs appearing in Fig. 20 and the pin designated as 107 by which the lever is
pivoted between the lugs appearing in Fig. 6. The free end of the other arm of
the lever is slotted as at 108, see Fig. 6, and a thumb screw 109 passes through
this slot and engages plate 106, see Fig. 3 in connection with Fig. 20 in which the
hole engaged by the screw is shown and is designated as 110. A spring 111 bears
upon the under side of plate 106 and upon the slotted arm of the lever and acts to
force the lever downward and consequently to hold the central wiper plate away
from the periphery of the glue roller. By turning the thumb screw in either
direction as may be required the central wiper plate may be adjusted in or out
relatively to the periphery of the glue roller. These wiper plates simply act to
prevent a large quantity of glue from being taken up by the glue roller and
communicated to the backs of the books. The glue roller is carried by a shaft 112
which is journaled in brackets 113 extending from the frame, see Figs. 1, 3, and 6,
21

page_text: and also carries a sprocket wheel 114. Motion is communicated to the glue rollers
by means of a sprocket chain 115 which passes over sprocket wheel 114 and over
sprocket wheel 4 on shaft 2. 116 denotes a cross piece, see Figs. 1, 3, and 7,
having hubs 117 in which a shaft 118 carrying a pinion 119 is journaled. This
pinion engages a rack 120 on a rod 121 which is itself supported by and is adapted
to be moved vertically in a boss or enlargement 122 on cross piece 116, the boss
being slotted to receive the pinion as indicated in Fig. 7. Upon the under side of
the glue tank is a boss or enlargement 123 having an opening to receive the upper
end of the rod. The glue tank is secured to the rod by a set screw 124, see Fig. 3,
which engages the rod. At the outer end of shaft 118 is a hand lever 125 by
which it may he oscillated. It will be seen that when the glue in the tank becomes
partially used up the tank may be raised as much as may be required by a slight
movement of the hand lever, it being of course understood that the steam
connection is flexible so as to permit the glue tank to be raised and lowered
whenever required.
E denotes the covers for the books which rest upon an adjustable table F. The
construction of this table will be clearly understood from Fig. 18 in connection
with Figs. 1, 3, 15 and 17, it being understood that the forward movement of the
table, which will presently be fully explained, is toward the top of the sheet as
seen in Fig. 18, toward the right in Fig. 1, toward the left in Figs. 3 and 15 and
forward from the point of view in Fig. 17. The table consists of three trans-
verse slides designated respectively by 126, 127 and 128 each of which is provided
with a slot 129 extending inward from one end, the opposite sides of the slides
being connected by metal strips 130, the slides being made of either metal or wood,
preferably of wood. Slides 126 and 128 are rigidly secured to a longitudinal
strip 131 and slide 127 is rigidly secured to a longitudinal strip 132 which also
extends over slides 126 and 128, these strips being preferably made of metal
and being provided on their outer sides with flanges 133. Bolts 134 pass
through strips 131 and 132 and through the slots, and the parts are locked
in position by nuts 135 on the under side see Fig. 15 also dotted lines in
Fig. 18. 136 denotes fixed supports against which the sides of the pile of
covers rest and G longitudinally adjustable supports against which the sides and
rear end of the pile of covers rest. These adjustable supports consist of angle
pieces 137 which lie upon the inner sides of flanges 133 and plates 138 which are
made integral with the angle piece or are rigidly secured thereto and lie on the
outer sides of the flanges, the supports as a whole being clamped to the flanges by
set screws 139. It will be readily understood therefore that any desired adjustment
of the table to accommodate different lengths of covers may be obtained by
loosening the set screws and moving the supports G forward or backward as may
be required and that adjustment to any required width of covers may be obtained
by loosening nuts 135 and moving slides 126 and 128 in one direction and slide 127
in the opposite direction. This table rests upon a platform 140 from which it may
be readily detached. The front end of the platform, see Fig. 15, is provided with
a flange 141 against which the table rests and by which the latter is held against
forward movement. At the rear end of the platform is a groove 142 which
receives a locking strip 143, see Figs. 1, 15, and 17. This platform may or may
not be solid. In the drawing, see Fig. 6 in connection with Fig. 15, we have
shown the platform as consisting of side and end strips denoted by 148 and one
cross piece denoted by 149. The special construction of the platform is however,
wholly immaterial. 144 denotes pins which extend from the side of slide 128 and
are adapted to engage notches in the locking strip thereby securing the table to
the strip the latter being held in position by the groove 142 which receives it.
Upon the under side of the platform are depending flanges 145 which are provided in
their inner faces with grooves 146 which receive gibs 147. This platform rests upon
rollers 150 journaled in a frame 151, see Fig. 16. The side strips of the platform
rest upon these rollers and gibs 147 bear against the sides of the frame, see Figs. 1
and 17, thereby retaining the platform against any except longitudinal movement

page_text: on the rollers. The gibs may be moved inward to take up lost motion by means of
gib screws 152. The longitudinal movement of the table and platform on
rollers 150 is wholly independent of the longitudinal movements of said parts with
cross piece 156, and is for the purpose of providing sufficient freedom of movement
for the table to compensate for any slight difference in the timing of the parts of
the machine or slight variations in the position in which the books may be grasped
and held by the chains, all of which will be again referred to. Frame 151 rests
upon and is rigidly secured to a vertically movable standard 153, which is provided
with a rack 154. This standard passes through a case 155 which depends from a
cross piece 156 itself carried by slides 157 which move on guide rods 158, the
latter being supported by bracket: 159 extending from the framework, see Figs. 6
and 7 in connection with Figs. 9 to 14 inclusive. Within the case and lying close
to the standard is a slide 160. 161 denotes a pinion which lies in a recess 162 in
slide 160 and is journaled on a stud 163 carried by said slide. 164 denotes a gear
wheel which is made integral with or rigidly secured to pinion 161 and of course
turns with it on the stud. Pinion 161 engages rack 154 on the standard and is the
only connection between slide 160 and the standard. 165 denotes a roller journaled
on a stud 166 which extends outward from the slide, passing through a slot 167 in
the side of the case, see Fig. 10. This roller rests upon a lever 168 which is
raised at regular intervals, thereby raising slide 160 and the standard, table &c.,
as will presently be fully explained, it being immaterial so far as the operation of
the parts illustrated in Figs. 9 to 14 inclusive is concerned how the upward
movement is imparted to this slide. The weight of the parts resting upon
lever 168 produces the downward movement as soon as the lever drops down.
169, see Fig. 10, denotes a pinion journaled on a stud 170 which extends outward
from slide 160. This pinion meshes with gear wheel 164 and has formed integral
therewith or rigidly secured thereto a beveled friction disk 171, the side of the case
being cut away as at 172, see Figs. 10 and 11, so as to permit the gear wheel and
pinion to move up or down freely with the slide. 173 denotes a friction wheel the
hub 174 of which is also journaled on stud 170. The inner face of this friction
wheel is provided with a beveled recess 175 the shape of which corresponds with
friction disk 171 so that when said friction wheel and friction disk are locked
together, as will presently be described, rotary movement imparted to the friction
wheel will be communicated to pinion 169 meshing with gear wheel 164 which in
turn carries pinion 161 engaging the rack on the standard. It will be seen
therefore that rotary movement imparted to the friction wheel acts through the
connections just described to raise the standard and with it the cover carrying.
table, the purpose of which will presently be fully explained, this movement of the
standard being independent of the movement produced by lever 168. 176, see
Figs. 3, 9, 10, 23, 24, and 25, denotes an arm which is rigidly secured to the case
and extends forward therefrom. In Fig. 10 this arm is shown as secured to the
case by bolts 177. This arm is provided with a slot 178 the purpose of which will
presently be apparent. The outer end of hub 174 is reduced as at 179, see Figs. 10
and 104, and carries arms 180 and 181 which are adapted to oscillate thereon.
These arms are retained in position on the hub by a nut 182 engaging a thread at
the outer end of the reduced portion. 183 denotes a nut engaging the threaded
outer end of stud 170 and bearing against the bub to press the latter inward
thereby forcing the wall of the beveled recess in the friction wheel against friction
disk 171 which locks the parts together so that rotary movement imparted to the
friction disk will through the pinions and gear wheel just described impart a
vertical movement to the standard and cover carrying table wholly independent of
the vertical movement of the standard imparted by lever 168. As will presently
be fully explained this independent upward movement of the standard is a
movement relative to slide 160 and takes place during the downward movement
of the table, platform, frame and standard, the object being to raise the table
slightly higher at each upward movement so as to compensate for the thickness of

simple connection between the friction wheel and the disk just described is to
provide convenient means for lowering the standard and cover carrying table when
a new lot of covers is placed upon the table without removal of parts from the
machine or any disturbance of the adjustments all of which will be again referred
to. 184 denotes an arm extending downward from the case at right angles to
185 denotes a link the ends of which are pivoted respectively to
arms 181 and 184, see Fig. 9, and which carries a shoe 186 which is adapted
to engage the periphery of the friction wheel, see Fig. 14, in connection with
Figs. 23, 24 and 25. 187 denotes the pivotal point of the link to arm 181,
and 188 denotes the pivotal point of the link to arm 184. A spring 189 extends
from the lower end of arm 181 and bears against a pin 190 extending outward
from the link, the action of this spring being to hold the shoe in engagement with
the periphery of the friction wheel. 191 denotes a link one end of which is
pivoted to arm 180 as at 192 the other end extending outward and being provided
with a slot 193 any portion of which is adapted to register with slot 178 in
arm 176. 194 denotes a bolt adapted to pass through these slots and provided
with a thumb nut 195 by which the link and the arm are locked together, the bolt
constituting a pivot on which the link oscillates at each upward and downward
movement of slide 160, the standard, table &c. 196 denotes a shoe which is
carried by link 191 and is adapted to engage the periphery of the friction wheel,
see Figs. 10, and 14 in connection with Figs. 23, 24, and 25. 197 denotes a spring
extending outward from arm 180 the free end of which bears against a più 198
extending outward from the link, the action of this spring being to hold the shoe in
engagement with the periphery of the friction wheel as will presently be fully
explained. 199 indicates a scale on link 191 for the guidance of the operator in
making fine adjustments of the pivotal point of link 191 to arm 176, it being
obvious that if the pivotal point i.e., bolt 194 is moved toward the right the
oscillation of the link at each upward and downward movement of slide 160, the
standard, table &c., will be lessened and if said pivotal point is moved toward
the left the oscillation of said link at each upward and downward movement of
slide 160, the standard, table &c., will be increased the friction wheel will have a
slightly increased forward movement imparted to it and the standard, table &c.,
will be raised a little more at each movement as would be necessary in changing
from thinner to thicker covers. As already stated the upward and downward
movements of slide 160, the standard, table &c., are produced by movements of
lever 168 which is engaged by roller 165 carried by slide 160 in the case.
inner end of this lever is pivoted on a cross piece 200, see Figs. 3 and 8, extending
transversely from side to side of the framework, 201 denoting the cap piece of the
bearing and 202 collars by which the lever is held against lateral displacement on
the cross piece. The free end of this lever carries a roller 203 which engages the
periphery of cam 32 on shaft 24. The shape of this cam is clearly shown in Fig. 3
in which it appears in dotted lines. It will be understood that each rotation of this
cam produces an oscillation of lever 168 and an even upward and downward
movement of slide 160, the standard, table &c., and that during more than one-half
of the rotation the lever and parts operating in connection therewith will be
stationary at their normal, i.e., the lowered position.
The
In connection with this movement it is necessary to consider the mechanism for
imparting longitudinal reciprocatory movement to the table. This movement is
produced by cam 27 on shaft 23 in connection with a lever 204 carrying a roller 205
which engages a groove 27" in said cam and a rod 206 one end of which is pivoted
to the free end of lever 204 and the other to the under side of cross piece 156, as
at 207, see Fig. 3 in connection with Figs. 7 and 8. The lower end of lever 204 is
pivoted on a cross piece 208 which extends across from side to side of the frame-
work. It will be obvious that cach rotation of cam 27 will produce a forward and
backward movement of cross piece 156 and the case, standard, table &c., which are
carried thereby. In order to insure however, that the top cover i.e., the one that
has been attached to the back of the book between the chains shall not adhere to

page_text: the cover below it we lay out groove 27* in cam 27 in such a manner that it will
impart to cross piece 156, the standard, table &c., an accelerated movement which
commences an instant after the top cover has become attached to the back of the
book. By accelerated movement we mean that the cover carrying table moves
forward faster than the book that is being carried by the chains. Simultaneously
with the acceleration of the forward movement of cross piece 156 the standard,
table, &c., the standard and table commence to move downward so that the actual
movement of the table and the pile of covers thereon is an oblique downward
movement which is faster than the forward movement of the book that is being
carried by the chains. The pile of covers is thus dragged forward and downward
away from the cover which has become attached to the book between the chains
while at the same time angle pieces 137 will press the attached cover forward
causing it to crinkle slightly so that all danger of a second cover adhering to the
one attached to the book is wholly prevented.
Turning now to Fig. 15 in connection with Figs. 1 and 3, 209 denotes a stop
against which the end of the book strikes as it is carried forward by the chains.
This stop is held by friction only in a guide 210 which is rigidly secured to the
platform. It will be obvious that as the standard, platform, table &c., are moved
upward the stop will be moved upward with them until it comes in contact with
lower plate 56 of chain carrying frame A. As the platform will continue to rise
until the top cover of the pile upon the table is raised high enough so that it will
adhere to the back of a book between the chains, it follows that the stop will he
pressed downward in the guide until it is level with the top of the pile of covers, in
which position it will move downward with the standard, platform, table, &c., after
the top cover has become attached to the book. Just before the next upward
movement of the platform, table, &c., takes place and while the table is at the
extreme of its movement toward the front, i.e., the left as the machine is seen in
Figs. 1, 2, 7 and 8 the stop is moved upward sufficient distance so that its upper end
will be higher than the top of the pile of covers and in position to be engaged by
the front end of the next book as it is carried along by the chains. This upward
movement of the stop is produced by cam 33 on shaft 24 in connection with a
lever 211. This lever, the shape of which is clearly shown in Fig. 3, is practically
a bell crank lever and is pivoted in a yoke 212 which extends toward the front
from cross piece 156, see Fig. 7 in connection with Figs. 1 and 3. The forward
end of the horizontal arm of this lever is widened as at 213 for engagement with
the lower end of the stop, and the lower end of the vertical arm of said lever is
provided with an extension 214 which is adapted to be engaged by cam 33 as
clearly shown in Figure 3, this extension being made sufficiently long to permit the
longitudinal movement of the lever with cross piece 156 without danger of the
extension passing off from the cam. 224, see Figs. 3 and 7, denotes a spring one end
of which is attached to cross piece 156 and the free end of which presses upon the
top of lever 211 acting to press the upper, .e., the horizontal arm of said lever
downward and to hold extension 214 upward in contact with cam 33 so that when
the operative portion of said cam comes in contact with the extension it will
tilt the lever and raise the stop, the spring returning the lever to its normal
position as soon as the operative portion of the cam passes it, the lever being
shown as tilted and in the act of raising the stop, in Fig. 3. In Figs. 1 and 3
the position of the parts is at the moment the stop has been raised by the
engagement of the can with the extension 214 of lever 211, just before the
upward movement of the standard, table &c., takes place, and the position in
Fig. 15 is at the moment the table has been raised to its highest position at which
instant the top cover thereou will engage the back of a book between the chains,
the pile of covers being designated by the letter E, and appearing in full lines
in Figs. 1 and 3, and indicated by dotted lines in Fig. 15. 215 denotes a
stop which is adapted to be engaged by the platform, see Figs. 1, 3, and 15, to limit
the backward movement of the platform and table i.e., the movement toward the
front. This stop extends upward from a block 216 which is carried by a cross
B

page_text: piece 217 extending transversely from side to side of the framework and serving as
a brace rod for the framework in addition to being a support for the block. 218,
see Figs. 15 and 17, denotes a lever which is pivoted to an arm 219 extending
downward from frame 151. One arm of this lever is pivoted to a yoke 220 on the
underside of platform 140, the pivot of this lever to the yoke lying in a slot so as
to permit oscillation of the lever. This slotted connection is indicated in Fig. 15
but is not shown in detail as it is an obvious mechanical expedient. The free arm
of this lever is bent inward at an angle, then downward and then backward as is
clearly shown in Fig. 17 in connection with Fig. 15, into position to engage
block 216 when the table moves backward after having been moved upward,
forward, and downward. The action of this lever is to move the platform and
table from any position relatively to frame 151 to which they may have been
carried by the forward movement of a book carried by the chains before the
downward movement takes place (leaving the top cover in engagement with the
back of the book) back to their normal position and before the next upward
movement takes place. This possible forward movement of the table and
platform relatively to the frame is indicated by a dotted position of the parts
in Fig. 15, the normal position of the frame and platform relatively to frame 151
being shown in full lines in said figure.
We will now describe the operation of the entire cover carrying mechanisin.
As has already been stated the books are fed to the chains by pusher 42 which is
of course timed with the other parts of the machine.
It will furthermore be
understood from the description of the cover carrying mechanism that the table
has four movements, that is to say, an upward movement, then a forward
movement, then an oblique downward movement and then a backward movement
to the starting point. In Figs. 1 and 3 the table is shown at what we have termed
the starting point, that is, at the backward position (ie. toward the front) and
ready to rise. The parts are so timed that the book is passing over the table
while the latter is rising. The forward end of the book first comes in contact
with sliding stop 209 which has already been raised through the action of
lever 211 and cam 33. This engagement of the book with the stop centers the
book relatively to the cover that is to be attached to it, the stop as already stated
having been moved above the top of the pile of covers but being pushed down to
the level of the top of the pile of covers by engagement with lower plate 56 of
chain carrying frame A as the table rises, so that when the top cover comes in
contact with the back of the book the stop will not extend above the top of the
pile of covers and will not interfere with the removal of the top cover from the
pile, by the book to which it has been attached. At the instant the top cover
comes in contact with the back of the book between the chains the forward
movement of the table will commence through the action of cam 27, lever 204 and
rod 206 which is pivoted to cross piece 156. The table now moves forward with
the book hetween the chains. This movement which takes but an instant permits
the cover to become firmly attached to the back of the book which has previously
passed over the surface of a glue roller as has already been fully explained.
An instant later the oblique downward movement of the table with the pile of
covers thereon takes place, angle pieces 137 causing the attached cover to crinkle
slightly as already explained so that the top cover is separated from the others
and all danger of the adhesion of a second cover to the attached cover is
prevented. In order to provide for a possible variation of the parts owing to the
manner in which the book may be grasped by the chains or from any cause
whatever we provide for a forward movement of the table and the pile of covers
thereon independently of the forward movement of cross piece 156, the standard
and frame 151. This movement results from the table and the platform to which
it is attached resting upon rollers 150 ou frame 151. This independent movement
of the table and platform relatively to the frame may or may not take place.
Suppose however, that cross piece 156, the standard and the frame are slightly
behind the book in the forward movement, any slight difference in timing or any

page_text: slight variation from normal in the position of the book that may exist at this
moment is fully compensated for by the freedom of the table and platform to move
forward with the book and chains independently of cross piece 156, the standard
and frame 151. This slight movement of the table and platform relatively to the
frame will be clearly understood from Fig. 15 in which a forward position of
the table and platform relatively to the frame is indicated by dotted lines. The
position of the standard, frame, platform and table at the end of the oblique
downward movement is indicated by dotted lines in Figs. 1 and 3. The instant
the oblique downward movement of the table ceases the backward movement takes
place through the action of cam 27, lever 204 and rod 206 as already fully
described. An instant later stop 209 is raised through the action of cam 33 and
lever 211. The parts are now in position for the next upward movement of the
standard, frame, platform and table which is produced through lever 168 the latter
being oscillated by cam 32. This lever is engaged by the roller 165 carried by
slide 160 in case 155. The slide also carries a pinion 161 which engages a rack on
the standard, this being the only connection between the slide and the standard.
Pinion 161 has formed integral with it or rigidly secured thereto a gear wheel 164
which meshes with a pinion 169 journaled on stud 170 which also carries a friction
disk 171 made integral with or rigidly secured to said pinion. Friction wheel 173
is also journaled on said stud and is locked to this friction disk so as to turn
with it. As the friction wheel is at all times locked against backward movement
either by shoe 186 or by shoe 196 it follows that each upward movement of
slide 160 will carry the standard, frame, platform and table with it through the
engagement of pinion 161 on slide 160 with the rack on the standard. In Fig. 24
we have illustrated a position of shoes 186 and 196 during the upward movement,
the space between shoe 196 and the periphery of the friction wheel being greatly
exaggerated so as to show clearly that shoe 196 does not hold during the upward
movement, the holding of the friction wheel against backward movement during
the upward movement of the slide, standard and parts carried thereby being
wholly performed by shoe 186, link 191 which carries shoe 196 being free to
oscillate on bolt 194 which serves as its pivot. Fig. 9 shows the position of the
parts at the moment the upward movement commences and Fig. 25 shows the
position of the parts at the end of the upward movement, link 191 shifting during
the upward movement from the position shown in Fig. 9 to that shown in Fig. 25.
These parts remain in the position shown in Fig. 25 during the forward movement
of cross piece 156, the case, standard, frame, platform and table and
consequently in this position when the downward movement commences,
the parts
shifting during the downward movement from the position shown in Fig. 25 back
to that shown in Fig. 9, Fig. 23 showing the position of the shoes while this
movement is taking place. The normal action of springs 189 and 197 is to hold
shoes 186 and 196 respectively in contact with the periphery of the friction wheel.
The relative position of arms 180 and 181 and links 185 and 191 is greatly
exaggerated in Figs. 9 and 25. This exaggeration is for the purpose of making
the action of the parts clear. As a matter of fact the springs merely act to hold
the shoes in contact with the periphery of the friction wheel but the locking
action is automatic as will be apparent with relation to shoe 186 from Fig. 24 and
with relation to shoe 196 from Fig. 23. It will be seen from Fig. 24 that the
engaging point of shoe 186 is beyond the point of intersection with the periphery
of the friction wheel of a line passing through the centers of stud 170 and pivotal
point 188 of link 185 which carries the shoe and from Fig. 23 that the engaging
point of shoe 196 is beyond the point of intersection with the periphery of the
friction wheel of a line passing through the centers of stud 170 and bolt 194
forming the pivot of link 191 which carries the shoe. During the upward
movement therefore the pivotal point 194 of link 191 being stationary and the
friction wheel moving upward it follows that the locking action of shoe 196 will be
relieved, and it is clearly apparent that any tendency of the friction wheel toward
backward movement will be locked by shoe 186, spring 189 acting at all times to
are

page_text: It
hold said shoe in contact with the periphery of the friction wheel and any tendency
toward backward movement of the friction wheel causing said shoe to act auto-
matically to check the movement. When the downward movement takes place,
however, the conditions change. The position of the parts at the instant the
downward movement commences is clearly shown in Fig. 25 and by dotted lines
in Fig. 23. The instant that the downward movement commences any tendency
toward backward movement of the friction wheel will be automatically checked
by shoe 196, said shoe being as already stated retained in contact with the
periphery of the friction wheel by spring 197, it having been deemed best as
already stated in Figs. 23 and 24 to indicate a clear space between shoes 186
and 196 respectively and the friction wheel in order to make clear the operation
of the parts. It will be understood furthermore owing to the fact that the engaging
point of shoe 196 with the periphery of the friction wheel is heyond the point of
intersection with the periphery of the friction wheel of a line passing through the
centers of stud 170 and bolt 194 that in order to permit the parts to change from
the position shown in Fig. 25 and in dotted lines in Fig. 23 to the position shown
in Fig. 9 and substantially that in full lines in Fig. 23 that it will be necessary for
the friction wheel to turn slightly on stud 170 on which it is journaled. This
movement will be readily understood from Fig. 23 the position in dotted lines
being the position at the beginning of the downward movement and the position
in full lines being the position at the end of the downward movement.
should furthermore be borne in mind that the bolt 194 which serves as a pivot
for link 191 carrying shoe 196 is fixed and neither moves up nor down. Now
as the engaging portion of shoe 196 holds the friction wheel at a certain point
in its periphery which we have indicated by 221 and as it is impossible for this
point to slip under the shoe it follows that unless the friction wheel turns forward on
its axis the downward movement will be blocked. Owing to the fact however,
that the friction wheel can turn forward on its axis the downward movement takes
place freely but during the downward movement sufficient rotation of the friction
wheel on its axis must take place to permit said friction wheel to move from the
position shown in dotted lines in Fig. 23 to the position shown in full lines in said
figure. Turning now to Fig. 10 it will be seen that this movement of the friction
wheel will carry pinion 169 meshing with gear wheel 164, and, the latter being
fixed to pinion 161 which engages the rack, that the rack must receive a slight
upward movement. The forward movement of pinion 169 is indicated approximately
in Fig. 23 in which a certain arbitrary place in the periphery of said pinion at the
beginning of the downward movement is indicated by 222 and the same point in
the periphery of said pinion at the end of the downward movement is indicated
by 223. It has already been stated and will be clearly understood from Fig. 23
that shoc 186 will not act to hold the friction wheel against forward movement but
only against backward movement so that during the downward movement there
is no check upon the carrying forward of the friction wheel by the engagement
with the periphery thereof of shoe 196. This forward movement of the friction
wheel and slight upward movement of the standard, frame, platform and table is
to compensate at each upward movement of these parts for the thickness of the
cover removed from the table at the last previous upward movement. Suppose for
example that the covers are each one one-hundredth of an inch in thickness. The
pivotal point of link 191 to arm 176 will be so adjusted as to impart sufficient
movement to pinion 161 to carry the standard, frame, platform, table &c. upward
one one-hundredth of an inch during each downward movement of the standard,
table &c. In order that this movement may be regulated to the minutest fraction
of an inch we provide a scale 199 on link 191 which is graduated to minute
fractions of an inch so that bolt 194 which is the pivot on which the link
oscillates may be set at any adjustment necessary to produce the required upward
movement of the standard, table &c., relatively to slide 160 while said parts are
moving downward. It will be apparent that by loosening thumb screw 195 and
moving bolt 194 toward the left as the parts are seen in Figs. 9, 10, 23, 24 and 25
.

page_text: the oscillation of the link at each upward and downward movement of the standard,.
table &c., will be increased and consequently an increased forward movement will
be imparted to the friction wheel and through the gear wheels and pinions an
increased upward movement relatively to slide 160 will be imparted to the standard,
frame, platform and table during each downward movement of said parts and that
when said bolt 194 is moved toward the right as seen in Figs. 9, 10, 23, 24 and 25
the oscillation of said lever will be lessened during each upward and downward
movement and consequently that the upward movement of the standard, frame,.
platform and table relatively to slide 160 will also be lessened. This is owing to
the fact that when bolt 194, which is the pivot on which link 191 oscillates, is.
moved toward the left engaging point 221 of shoe 196 on the friction wheel moves
in an arc of a greater circle than when it is moved toward the right. When the bolt
is moved toward the left therefore the engaging point has a slightly longer contact
with the friction wheel and consequently imparts slightly increased movement to
the friction wheel. When the bolt is moved toward the right the effect is just the
reverse and less movement is imparted to the friction wheel. Suppose now that
the machine commences to work with a pile of covers upon the table six inches.
high. It will be apparent in view of the fact that the table descends a slightly
decreased distance at each downward movement that when the pile of covers shall
be exhausted, the lowered position of the table will be six inches higher than the
lowered position of the table when work was commenced upon that special pile of
covers and consequently that it will be necessary to lower the table, platform, frame
and standard relatively to slide 160 before a new pile of covers can be placed on
the table. This is accomplished by loosening nut 183 at the outer end of stul 170
which relieves the engagement of the wall of the beveled recess in the friction
wheel with friction disk 171. This permits pinions 161 and 169 and gear
wheel 164 to be rotated backward without carrying the friction wheel. Having
loosened nut 183 as already stated the operator presses down the table, platform,
frame and standard in the case as far as may be required, it being understood of
course that as the standard is pressed down the rack will engage pinion 161 and
will rotate said pinion, gear wheel 164 and pinion 169 but wholly independently of
the friction wheel which is held as at all times by shoes 186 and 196. The distance.
the table is required to be moved down depends of course upon the height of the
pile of covers that is to be operated upon, it being of course necessary to so adjust
the table in starting that at the raised position the top cover will engage the back
of a book that is being carried along by the chains. Having placed the table at
the desired adjustment it is locked there by tightening up nut 183 and the machine
is ready for operation as before.
225 denotes a table supported by any suitable portion of the framework of the
machine, see Figs. 1 and 3 over which the back of the book passes as it is carried
along by the chains and over which the attached cover passes. This table retains
the cover in a horizontal position, that is, it prevents the sides of the cover from
dropping down away from the back of the book. The rear end of the table is
inclined downward as clearly shown so as to prevent any possibility of the cover
catching upon the rear end of the table and being torn off or crumpled as it is
carried forward by the chains. 227 denotes a pusher carried by a slide 228 which
noves in guides 229 attached to the vertical plate 226 on chain carrying frame A,
see Figs. 2 and 24. The pusher is pivoted in a slot at the forward end of the slide
and the forward end of the pusher extends inward obliquely and passes through
sluts 230 in plates 220, see Figs. 1 and 3, in which the slot in the plate 2/6 forming
part of frame A is clearly shown. A spring 231 acts upon the pusher to retain it
in its normal position, the inward movement of the pusher being checked by a wall.
of metal 232, see Fig. 2^, which serves as a stop. As the book is carried along
by the chains the cover lying out flat and resting upon table 225 the front end of
the book will come in contact with pusher 227 and will move it backward out of
the way against the power of the spring as indicated by dotted lines in Fig, 24.
As soon as the book has passed the pusher the spring will return the latter to its.

page_text: normal position as indicated in full lines, the front end of the pusher at this instant
lying just back of the book. The machine is so timed that the instant pusher 227
has been moved into position back of the book, the slide carrying the pusher with
it will begin to move forward, and as soon as the book is released by the chains it
will be moved forward away from the chains by the pusher until the back of the
book rests upon a platform 233, see Figs. 4, 5, and 6, in which the position of the
platform at the instant it receives the book is shown in dotted lines and its
retracted position is shown in full lines, the cover at this time lying out Hat on
table 225. Slide 228 receives longitudinal reciprocatory movement through
cam 29. This cam is provided in its face with a groove 234 which receives a
roller 235 carried by an arm 236 which extends downward from a rock shaft 237
journaled in a bearing 238 supported by any suitable portion of the framework.
From the inner end of this rock shaft an arm 239 extends upward. 240 denotes a
link one end of which is pivoted to arm 239 and the other to slide 228. It will be
apparent that each rotation of the cam will produce a forward and backward
movement of the slide and pusher 227. 241 denotes plates adapted to slide in
ways 242 formed upon the upper plates 55 of chain carrying frames A and B.
These plates are adapted to be moved in or out in changing the machine to
accommodate thinner and thicker books and are locked to the chain carrying
frames after adjustment by bolts 243 which pass through slots in plates 241 and
engage plates 55. Each of the plates 241 carries a vertical plate 244 which extends
upward therefrom at right angles and also extends toward the front and rear ends
of the machine as will be clearly understood from Fig. 2 in connection with Fig. 1,
the ends of plates 244 toward the front of the machine extending up to the forward
ends of plates 226 but having no connection therewith. Plates 244 are provided on
their inner faces with vertical grooves 245 which receive the wings 246 of a
vertically moving pusher 247 which acts to move the books downward between
other plates presently to be described which set the covers to the sides of the
books and into position to be operated upon by the cover setting roller.
This
pusher is carried by a rod 248 supported in guides 249 one of which is cast
integral with or rigidly secured to the lower portion of the frame, the other
being cast integral with or rigidly secured to end casting 78, see Fig. 4.
The pusher is rigidly secured to a collar 250 which is itself secured to
rod 248 by a set screw 251 see Figs. 3, 4, and 5. The wings upon the
pusher engage the front edge of the book and act to push it down, the width
of the book being compensated for by adjustment of the pusher on the rod
and the adjustment to different thicknesses of books being compensated for
by loosening bolts 243 which pass through slots in the plates 241 which carry
the vertical plates 244 and tightening them again after adjustment of the piates.
The rod carrying the pusher with it is reciprocated by means of a lever 253 which
is pivoted on a stud 254 extending from any suitable portion of the framework,
see Fig. 8, the free end of said lever being pivoted to a link 255 which is itself
pivoted to the lower end of the rod as clearly shown in Figs. 1, 3, and 4.
rear end of lever 253 is a roller 256, see dotted lines in Fig. 3, which is held by
the weight of the rod, pusher &c., in engagement with a wall 237 on cam 31, see
Figs. 3 and 8, said cam being provided on one side with a flange 258 which acts at
a certain portion of each revolution of the cam to raise the rear end of lever 253
and consequently to lower the forward end thereof thereby drawing down, and
pusher. A spring 259, see Fig. 8, acts to partially overcome the weight of the
rod and pusher so as to partially relieve the strain upon the cam. It will be
readily understood that each rotation of said cam will produce an upward and
downward movement of the rod and pusher. We have for the sake of clearness
described the operation of the pusher before describing the operation of
platform 233. It will of course be understood however, that before the book can
be moved down by pusher 247 platform 233 must have been moved out of the
way. This movement we will now describe in connection with another movement
which is produced by the same mechanism. 260, see Figs. 4, 5, and 7, denotes a
At the

page_text: plate which is rigidly secured to the opposite sides of the framework, said plate
resting upon ledges 261 which are cast upon the framework. This plate has
cast in it a trough 262 the purpose of which will presently be explained.
263 denotes a fixed squeezer plate and 264 a movable squeezer plate. These
plates have formed integral with them angle plates 265 which rest upon plate 260
webs 266 being formed between the angle plates and the squeezer plates in order to
give the necessary amount of strength to the squeezer plates. We have described
plate 263 as a fixed squeezer plate for the reason that it is fixed in usc. It is
however, adjustable in or out, to provide for thinner or thicker books, between
ways 267, see Fig. 7, formed upon plate 260 and is locked in place after adjust-
ment by a cap plate 268 which is clamped down upon it and is secured to the
ways by bolts 269, see Figs. 1 and 7. Movable squeezer plate 264 lies between
waye 270, see Fig. on plate 260 and is held in place by a cap plate 271 which
however, simply holds it in place but does not clamp it, leaving it free to slide
between the ways. Both of the squeezer plates as well as platform 233 are
provided with grooves 245, sec Figs. 6 and 7 which receive the wings upon
pusher 247 freely. 272, see Figs. 4, 5, and 7 deuotes springs the respective ends
of which are connected to the movable squeezer plate and cap plate 271 and which
act to move said squeezer plate out of operative position. Platform 233 has upon
its underside a boss 273 through which a rod 274 passes, the boss being locked to
the rod by a set screw 275. This rod is adapted to slide in bosses 276 on the
under side of table 225, see Figs. 1 and 5. A spring 277, see Fig. 5, is connected
to one of the bosses 276, the right as seen in Fig. 5 and to boss 273, the action of
said spring being to move the platform toward the receiving position and retain it
there, said position being indicated by dotted line in Figs. 4, 5, and 6. At one end
of rod 274, the left as seen in Fig. 5, is a downwardly extending arm 278 which is
provided at its lower end with a set screw 279 and with a check nut 280 to retain
the set screw in position after adjustment. 281, see Figs. 5 and 7, is an arm
extending upward from cap plate 271 to which a lever 282 is pivoted. The upper
arm of this lever is engaged by the inner end of set screw 279. The oscillation
of this arm of the lever acts to move rod 274 toward the left as seen in Fig. 5
and to move the platform from the position shown in dotted lines in Figs. 4, 5,
and 6 to the position shown in full lines in said figs. This movement takes place
just before the downward movement of pusher 247 so that when said movement
takes place the book may be carried downward by the pusher without obstruction.
The purpose of set screw 279 in arm 278 is to provide such adjustment for the
platform as may be necessary in use owing to lost motion or changes in thickness
of the books. The rear end of platform 233 is supported only by rod 274, the
front end of said platform resting on a ledge 283 formed upon table 225, said
table being provided with an opening 284 in which the platform moves.
lower end of lever 282 is engaged by a lever 285 the forward end of which is
pivoted to any suitable portion of the framework at the right end of the machine,
in the present instance to plate 260, see Figs. 4 aud 5 in connection with Fig. 8.
286 denotes an arm extending upward from lever 285, see Figs. 5, 7, and 8, which
carries a set screw 287, the inner end of which engages the outer edge of the
angle plate 265 of movable squeezer plate 264, see dotted lines Figs. 5 and 7.
The object of the set screw is to determine the pressure exercised by the movable
squeezer plate upon a book lying between said plates, it heing obvious that
springs 272 will act to hold the angle plate forming part of the movable squeezer
plate against the set screw and will also act to move the squeezer plate out of
operative position as soon as the pressure exercised by lever 285 is relieved.
A check nut 288 serves to lock the set screw in position after adjustinent. It will
be obvious from what has already been said that the platform 233 upon which the
books rest after being removed from the chains, is operated by lever 282 and that
lever 282 is operated by lever 285, which also operates the movable squeezer plate
and is itself operated by cam 34. At the rear end of lever 285, that is the
eud toward the front of the machine, is a roller 289 which engages the face
The

page_text: of cam 34. 290 is a supplemental lever the forward end of which is pivoted to
lever 28 and the rear end of which carries a roller 291 which is also adapted to
engage the face of cam 34. It will be understood from the arrow in Fig. 8 that
roller 291 will engage the face of cam 34 in advance of roller 289 and it will be
noticed furthermore in said fig. that the engaging points of rollers 289 and 291
lie in different vertical planes, roller 291 being so located that when the face of
the cam engages roller 289 said roller 291 will be moved forward wholly out of
contact with the face of the cam and lever 285 will receive additional movement,
the purpose of which we shall presently fully explain. We have made no attempt
to define geometrically the location of rollers 289 and 291 relatively to the face of
cam 34 as it is obvious that the arrangement of these parts may be greatly varied
without departing from the principle of our invention, the object being to obtain
through the engagement of one roller with the face of the cam a certain move-
ment of lever 285 and to obtain a further movement of said lever in the same
direction through the engagement of the second roller with the face of the cam.
This additional movement which is effected by the engagement of roller 289 with
the face of cam 34 is also subject to adjustment. 292 is a lug on the under side of
Jever 285 and 293 is a lug on the upper side of supplemental lever 290.
294 is a
set screw engaging these lugs, see Figs. 8 and S4, the parts being so arranged that
rotation of the set screw will oscillate supplemental lever 290 relatively to
lever 285 so as to move the engaging points of rollers 289 and 291 toward or from
each other thereby increasing or diminishing the additional movement imparted to
lever 285 by the engagement of the second roller with the face of cam 34. For
the sake of clearness, before proceeding to describe other movements we will
explain the operation of the parts just described. As already stated the books as
they are moved forward from between the chains by pusher 227 are received
upon platform 233 which lies in opening 284 in table 225 in the position
shown in dotted lines in Figs. 4, 5, and 6, the cover at this time lying out
flat upon said table 225 and the sides of the books being supported by
vertical plates 244. An instant later platform 233 is moved from the
position shown in dotted lines in Figs. 4, 5, and 6 to the position shown in
full lines in said figs. leaving the backs of the books unsupported, this move-
ment being effected as just described by means of levers 282 and 285. Simul-
taneously with the movement of the platform movable squeezer plate 264 is moved
forward toward its operative position through the engagement of roller 291 on
lever 285 with the face of cam 34. This first movement of the moveable squeezer
plate does not however, interfere with the downward movement of the book.
The effect of this movement, the parts having been properly adjusted in the manner
already described is to place the inovable squeezer plate in such a position that as
the book is pressed downward between the two squeezer plates the cover will be
pressed up closely against the sides of the book. It will be noticed in Figs. 4
and 5 that the upper ends of the two squeezer plates are rounded so that as the
covers are drawn over the upper ends thereof there will be no danger of tearing the
covers, the rounded upper ends serving to close them up against the sides of the book.
The instant the platform is out of the way pusher 247 begins to move downward
and at the instant the downward movement of the pusher is completed the movable
squeezer plate will again be moved forward through the engageinent of roller 289
with the face of cam 34. The engagement of this roller with the face of the cam
will throw roller 291 still farther forward placing it entirely out of engagement with
the cam and will impart additional movement to lever 285, the effect of which will
be to move squeezer plate 264 forward with sufficient force to clamp the book
firmly and hold it, the sides of the cover being of course firmly pressed against the
sides of the book. The book is now in position to be operated upon by the cover
setting roller. This roller which we have designated by 295, see Figs. 3, 4, and 7,
is at the forward end of a slide 296 which lies in trough 262. At the instant the
book has been moved down by pusher 247 and has been clamped between the
squeezer plates by the second forward movement of squeezer plate 264, slide 296

page_text: will be at the extreme of its forward movement as indicated in dotted lines in Figs. 3
and 7. It will be noticed in Fig. 3 that the top of the roller lies slightly above
the top of the slide and in such a position that when the backward movement of the
slide takes place the roller will press firmly upon the back of the book which firmly
sets the cover in place thereon. During this backward movement as already stated
the book will remain firmly clamped between the squeezer plates so that it will not
be pressed upward by roller 295 but said roller will press firmly thereon to set the
cover. At the instant however, that the backward movement of the slide shall
have been completed roller 289 will pass off from the face of cam 34, see Fig. 8A
in connection with Fig. 8 which will relieve the pressure of the movable squeezer
plate upon the book for the reason that springs 272 will at once move squeezer
plate 264 backward entirely out of the way so that the book will drop down into
the trough by gravity. An instant. later the forward movement of slide 296 takes
place, said slide, in the present instance the roller thereon, now acting as an ejector
and carrying the book forward out of the trough. The reciprocatory movement of
this slide which serves the double purpose of setting the covers upon the backs of
the books and also of moving the covered books forward out of the machine is
derived from cam 28 through suitable intermediate connections. 297 denotes a rod
the forward end of which is pivoted to the rear end of slide 296, the rear end of
said rod being pivoted to an arm 298 which extends from a rock shaft 299 journaled
in the framework, see Figs. 3 and 7. 300 denotes another arm extending from
rock shaft 299. 301 denotes an arm having at its lower end a hub 302 which is
journaled on cross piece 208. This arm carries a roller 303 which engages a

groove 304 in the face of cam 28, see dotted lines Fig. 3.
end of which is pivoted to the outer end of arm 301, the other end of said link
being pivoted to the outer end of arm 300 which extends outward from the rock shaft.
It will be readily appareut that each rotation of the cam must produce an oscillation
of arm 301 which by means of link 305 and arm 300 will produce an oscillation of
the rock shaft and arm 298 to which rod 297 is pivoted and will cause a backward
movement of the slide and cover setting roller which sets the cover upon the back
of the book and a forward movement of said slide which pushes the book out from
the trough and onto a receiving table 306 which is secured at the forward end of
the trough in any suitable manner as by a plate 307 attached to the underside
of the receiving table and the under side of the trough, see Figs. 2 and 4, and is
supported by suitable lugs or standards 308, see Fig. 1. 309, see Fig. 8B in
connection with Figs. 1 and 2, denotes a plate secured to the under side of the
receiving table and extending outward therefrom. This plate is provided with a
slot 310 and on its under side with lugs 311 through which a rod 312 reciprocates.
313 denotes a collar rigidly secured to this rod and 314 an arm extending upward
through the slot and having at its forward end a plate 315 to which is secured a
board which serves as a pusher to move the covered books forward on the receiving
table and is designated as 316. 317 denotes springs secured to the bottom and
outer wall 318 of the receiving table. The free ends of these springs are curved
upward and then over so as to leave smooth ends to rest against the cover of the
last book received. Recesses 319 are provided in the bottom and outer side of the
pusher to receive these springs and holes 320 are formed in the bottom of the table
and in the outer wall thereof to receive the ends of the springs, see Figs. 2
and 8A.
321 denotes a suitable support against which the first book received from the
machine is pressed by the pusher. This support is made heavy enough to retain
the books in an upright position and is moved forward the thickness of a book each
time a book is received from the machine and moved forward laterally by the
pusher. The pusher is reciprocated laterally to the machine by means of a
lever 322, see Figs. 3 and 8, which is connected to the end of rod 312 by means of
a link 323. Lever 322 is pivoted on a stud 324 which extends downward from the
framework and carries at its rear end, that is the end toward the front of the
machine, a roller 325, see Fig. 3 also dotted lines Fig. 8, which engages a groove 326
C

page_text: in cam 35. It will be apparent that each rotation of this cam will produce a
forward and backward movement of rod 312 and pusher 316. As each book is
pushed out of the machine by slide 296 the pusher will be at its extreme retracted
position as in Fig. 2. The instant the book is received the pusher begins to move
forward carrying the book before it and pressing springs 317 downward, the springs
themselves lying in recesses 319 in the pusher and the ends of the springs being
pressed into holes 320 in the bottom and outer wall of the receiving table. This
permits the book to be pushed over the ends of the springs, the pusher itself
stopping before it has passed off from the springs. An instant later the return
movement of the pusher takes place and the springs return to the position in which
they are shown in Fig. 2 and retain the last book in an upright position.
The operation of the machine as a whole is briefly as follows: The books to be
covered are stacked upon table 36 and the pile of covers is placed upon table F.
The operator stands at the front end of the machine and places the books singly
in front of pusher 42. Each reciprocation of this pusher carries a book forward
far enough to be grasped firmly by the book carrying chains C. As the books are
carried along by the chains they are held against falling open by vertical plates 226
between which they pass. The backs of the books pass over a glue roller which
deposits sufficient glue on the back of each book so that the cover will stick to it.
The instant a book has passed off from the glue roller the table rises and the top
cover thereon adheres to the back of the book, the table moving forward a short
distance with the book so that the cover will not be removed therefrom. The
table then drops downward obliquely out of the way and then moves backward into
position to rise again and place a cover in contact with the back of the next book,
special mechanism being provided which compensates before each rise of the table
for the thickness of the cover last removed therefrom. An instant after the cover
which has been attached to the back of a book passes off from table F. it passes
upon a table 225, still lying out flat. A pusher 227 now acts upon the book to
push it out from between the chains and upon a platform 233 lying in an opening 284
in table 225. An instant later this platform is moved laterally out of the way and
a pusher 247 moves the book downward between plates 263 and 264 which fold the
sides of the cover against the sides of the book. An instant later one of these
plates moves forward and clamps the book tightly between the said plates. While
the book is held in this position a cover setting roller passes backward over the back
of the book and sets the cover firmly thereto. An instant later the pressure
of the movable squeezer plate is relieved and the book drops down into
the trough in which the slide carrying the cover setting roller reciprocates. An
instant later this slide moves forward and carries the book out of the machine and
on to the receiving table. A. pusher upon this table moves each book forward
laterally out of the way as soon as it passes upon the table in which position it is
held by springs when the pusher moves backward to permit another book to be
moved in front of it by the slide moving in the trough.

the pusher and for moving the squeezer plate inward a second time to clamp the
book between said plates in which position the cover is set by the cover setting
roller, said mechanism then relieving the pressure upon the squeezer plate
and permitting the book to drop down from which position it is expelled by the
slide.
78. In a machine of the character described the combination with platform 233
adapted to receive a book back downward plates 244 which support the sides of
the book and table 225 upon which the attached cover rests, of the fixed squeezer
plate, the movable squeez r plate, levers 282 and 285 and intermediate connections
by which the platform is moved outward and the movable squeezer plate is moved
inward, pusher 247 acting an instant later to press the book downward between the
squeezer plates whereby the cover is folded to the sides of the book, the movable
squeezer plate then moving inward again and clamping the book, a slide carrying
a roller which sets the cover upon the back of the book, the pressure of the
squeezer plate then being removed and the book dropping down and said slide
acting to expel the book."
79. In a machine of the character described the combination with plates 244,
the platform and the fixed and movable squeezer plates, said plates and said
platform having grooves 245, of pusher 247 having wings lying in said grooves,
mechanism for moving the platform laterally out of the way of the pusher,
rod 248 by which the pusher is carried, lever 253, a link connecting said lever
and rod and a cam by which the lever is oscillated to reciprocate said rod and
pusher.
80. In a machine of the character described the combination with receiving
table 306 and slide 296, of plate 309 extending outward from the receiving table
and provided with a slot 310 and lugs 311, pusher 316 secured to a plate 315 upon
an arm 314, said arm passing through the slot and having at its lower end a
collar 313, rod 312 which slides in said lugs and to which collar 313 is secured and
suitable means for reciprocating said rod by which the pusher is moved laterally
on the receiving table and carries the books out of the way as fast as they are
passed to the table by slide 296.
81. In a machine of the character described the combination with carrying
chains by which the books are carried backs downward, and a glue roller, of a
table by which the covers are carried, mechanism for moving said table upward
and downward, and mechanism for moving said table forward and backward, the
forward movement of said table being at a greater speed than the speed of the
book carried by the chains and the downward movement commencing before
the forward movement is finished so that the movement of the table is forward
and downward obliquely at greater speed than the book is moving whereby a
second cover is prevented from adhering to the cover attached to the back of the
book.
82. The combination with the carrying chains operating substantially, as
described and a glue roller, of a table by which the covers are carried, mechanism
for reciprocating said table in the horizontal plane and mechanism for reciprocating
said table in the vertical plane, the parts being so arranged and timed that the
table will move upward and place a cover upon the back of a book between the
chains, will then move forward and downward obliquely at a greater speed than
the book is moving so that the pile of covers is dragged forward and downward
away from the cover attached to the book, the table then moving backward into
position for the next upward movement.
83. In a machine of the character described the combination with chains by
which the books are carried backs downward, a glue roller, a table by which the
covers are carried and a standard by which the table is carried, of a cross piece by
which the standard is carried, mechanism for reciprocating the standard vertically
in the cross piece and mechanism for reciprocating the cross piece longitudinally of
the machine, the operation of said parts being so timed that after the upward

page_text: movement of the standard and table by which the top cover is attached to a book
between the chains the forward movement of the table will be at greater speed
than the book is moving and the downward movement will commence before
the forward movement is finished so that the table and covers are dragged forward
and downward away from the book and the adhesion of a second cover to the
attached cover is prevented.
84. In a machine of the character described the combination with chains by
which the books are carried backs downward, a glue roller, a table by which the
covers are carried and a standard by which the table is carried, of a cross
piece by which the standard is carried, cam 32 and lever 168 by which the
standard is reciprocated in the cross piece, cam 27 having a groove 27ª and
mechanism intermediate said cam and the cross piece by which, the. latter is
reciprocated longitudinally, said groove 27 being so laid out as to cause forward
movement of the cross piece, standard and table at a greater speed than the
book is carried forward by the chains as and for the purpose set forth.
.
85. In a machine of the character described the combination with chains by
which the books are carried and a glue roller, of a table by which the covers are
carried and which is provided with angle pieces 137, mechanism for reciprocating
said table in the horizontal plane, and mechanism for reciprocating said table in
the vertical plane, the parts being so arranged and timed that the table will move
upward and place a cover upon the back of a book between the chains and will-
then move forward and downward obliquely at a greater speed than the book is
moving, angle pieces 137 pressing the attached cover forward causing it to crinkle
slightly so that danger of a second cover adhering to the attached cover is
prevented.
86. The combination with carrying chains by which the books are carried backs
downward and a glue roller, of a table by which the covers are carried and which
is provided with angle pieces 137 against which the rear ends of the covers rest
and mechanism operating substantially as described and shown which raises the
table and permits the top cover to adhere to the back of the book, then moves the
table forward with the book between the chains, and then moves the table forward
and downward obliquely at a greater speed than a book between the chains is
moving so that angle pieces 137 will press against the attached cover and crinkle
it slightly the table with the pile of covers thereon being dragged forward and
downward away from the attached cover so that the adhesion thereto of a second
cover is prevented.
87. The combination with carrying chains by which the books are carried backs
downward and a glue roller, of a table by which the books are carried and which
is provided with angle pieces 137, a standard by which the table is carried,
mechanism intermediate said standard and table by which the table is permitted to
move forward independently of the standard, mechanism for moving the standard
and table upward and downward and mechanism for moving the standard and table
forward and backward, the downward movement of the standard and table com-
mencing before the forward movement is finished and the forward movement from
the instant the downward movement commences being at greater speed than the
books are carried by the chains so that the attached cover will be crinkled slightly
by angle pieces 137 and the pile of covers on the table will be dragged forward
and downward away from the attached cover as and for the purpose set forth.
88. The combination with carrying chains by which the books are carried backs
downward and a glue roller, of a table by which the books are carried and which
is provided at its rear end with angle pieces 137 and at its forward end with a
sliding stop 209 which is adapted to be engaged by the forward end of a book
between the chains, a standard by which the table is carried, mechanism inter-
mediate said standard and table by which the table is permitted to move forward
independently of the standard, for the purpose set forth when stop 209 is engaged
by the book, mechanism for moving the standard and table upward and downward
and mechanism for moving the standard and table forward and backward, the

page_text: downward movement of the standard and table commencing before the forward
movement is finished and the forward movement from the instant the downward
movement commences being at a greater speed than the books are carried by the
chains so that the attached cover will be crinkled slightly by angle pieces 137 and
the pile of covers on the table will be dragged forward and downward away from 5
the attached cover.
