JOHN CROWLE SMITH, of 25 Lloyd Square, London, W.C., England, 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 invention relates to the class of machines which apply the stiffening to the
outside of book covers or cases, the object being to provide a machine that will
automatically and continuously form completed cases by gluing and folding the
cloths about the boards and back linings, which is readily adjustable for forming
cases of various sizes and shapes. To this end the invention resides in a machine
having receptacles for the boards and back linings, and co-operating mechanisms
for, at intervals, transferring the boards and back linings from the receptacles to
the cloths; for gluing the cloths and folding them around the boards and back
linings;
and for discharging the completed cases from the machine and hardening
the glue, as more particularly hereinafter described.

In the views 1 indicates the frame of the machine. Near the front of the
machine supported by the sides transversely is a shaft, 2, loosely mounted upon
which is a cylinder or segment of a cylinder, 3, with a number of gripping 2
fingers, 4. Fastened to this shaft, 2, is a pinion, 5, with which meshes a rack, 6, on
a lever, 7, pivoted on a stud, 8, projecting from one side of the frame. A roller on this
lever engages the cam, 9, fast to the cam shaft, 10. The shaft, 2, has an arm, 11, with
a spring pin, 12, that projects into the path of a hooked arin, 13, on a rod, 14, that
extends the length of the cylinder and bears the fingers, 4.
A gear, 15, on this 2
shaft, 2, meshes with a gear, 16, on shaft, 17, that bears sheaves, 18, around which
and the sheaves, 19, pass cords, 20, that are fastened to the ends of a rod, 21,
loosely held by slotted plates, 22, to a slide, 23, that is free to move, with its ends
in the grooves, 24, in the sides of the frame, toward and from the cylinder.
Fingers, 25, project from the front edge of this slide, and complementary 3
fingers, 26, project from a rod, 27, loosely held by the plates, 22, and provided
with arms, 28, that rest on the rod, 21. (Figs. 4, 5, 6, 7, 8.)
Below the cylinder on the main driving shaft, 30, is a roller, 29, dipping into a
tank or glue receptacle, 31, that has a heating chamber below for keeping the glue
liquid. On the shaft, 30, is the driving pulley, 32, and a gear, 33, meshing with an 3
idle gear, 34, that meshes with a gear, 35, on a shaft bearing a gear, 36, in mesh
with a gear, 37, on cam shaft 10. (Figs. 25, 26.)
The rotation of cam 9 oscillates lever 7 with rack 6 which through pinion 5
rotates shaft 2 alternately in opposite directions. A piece of cloth of the proper
size is laid upon the cylinder with its edges under the fingers, 4, and when the 4
shaft, 2, starts the spring pin, 12, on the arm, 11, engages the hook, 13, and first
closes down the fingers so they grip the cloth, then further rotation of the shaft
and arm carries the cylinder around, causing the cloth on its surface to rub in
contact with the surface on the roller, 29, and become besmeared with glue. The
return movement of the rack rotates the shaft in the opposite direction, carrying
the arm around without rotating the cylinder. The cam is cut to rotate the
shaft slightly more than a revolution so that the pin, 12, will stop away from
the hook, 13, allowing it to drop by gravity so as to lift the fingers and release the
cloth. The shaft, 2, through the gears, 15 and 16, rotates the sheaves, 18, so the
cords, 20, draw up the slide, 23, to grasp the cloth as the fingers or the cylinder 5
release it, and when the shaft, 2, rotates in the opposite direction the sheaves and
cord take back the slide which draws with it the cloth. When the cord begins to
pull, the rod, 21, moves to the front end of the slots in the plates, 22, which allows
the arms, 28, to drop and open the fingers so as to receive the cloth when they
reach the cylinder, and when the cord commences to pull back, the rod moves to 5
the rear end of the slots, first closing the fingers upon the cloth by means of the
arms, 28, then pulling the slide and the glued cloth backward.

page_text: Extending transversely of the machine with their ends in grooves near the top
of the sides are bars, 38, 39, 40, and 41, and extending longitudinally at a lower
level are bars, 42 and 43, supported at the front by a cross beam, 44, and near the
middle upon the top of the wall, 45. (Figs. 18, 19.) Near the rear between the
bars, 40, 41, 42, and 43, is the board and back lining receptacle which is formed by
the corner posts, 46, that are adjustably held to both the longitudinal and transverse
bars, and the center guides, 47, the boards being held on each side and the back
linings in the center on an elevating bottom which raises the boards and the back
linings up to the picker after each removal. The boards being much the thicker,
after each removal have to be raised further than the back linings, so the bottom
of the receptacle, or the elevator, is formed with two side floors, 48, for the boards,
supported upon a tube, 51, and a center floor, 49, for the back linings, supported
upon a column, 50, that passes through the tube, 51. (Figs. 9, 10.) The tube, 51,
has teeth on one side and is held by a bracket, 52, that projects from the wall, 45.
On one end of a short shaft supported in a bearing, 53, on the bracket, 52, is an
arm, 54, that holds a spring pawl, 55, in contact with the teeth of the tube, and on
the other end of this short shaft is a lever, 56, that extends forward to the vicinity
of the picker column, 60, where the lever bears an arm, 57, with a latch, 58.
From one side of the picker column, 60, projects a pin, 61, that when the picker is
revolved into one position enters the slot, 59, between the end of the lever and the
latch so that when the picker column reciprocates the pin oscillates the lever, 56,
and causes the pawl to lift the elevator and raise the boards and back linings a
distance equal to the thickness of the boards, to lift the next into the position of
those removed. (Figs. 9, 10, 11, 12, 13, 14.) Of course, as the back linings are
not as thick as the boards, they will be lifted too great a distance, but as the
column of the floor which supports the back linings is simply held in the elevator
tube by friction the back linings which are raised too high are pushed down by the
pressure of the picker as it descends to pick up the boards.
The picker column, 60, which is loosely held in bearings secured to the wall, 45,
and is vertically reciprocated by a lever, 62, oscillated by cam, 63, on shaft, 10,
has keyed to it a segmental gear, 64, meshing with which is a rack, 65, supported
between the end of the upper column-bearing and a plate, 66, secured to said
bearing. This rack is connected by a link, 67, with a lever, 68, that is oscillated
by cam, 69, on shaft, 10. Upon the upper end of the picker column is the picker
arm, 70, that has a board, 71, which may bear on the under surface picking
pins, 72. (Figs. 15, 16, 17.) Secured to the wall, 45, is a cylinder, 73, in which a
piston, 74, is reciprocated when the lever, 75, is oscillated by cam 76 on shaft 10,
forming a pump. From the closed end of this cylinder a tube, 77, leads to
openings, 78, made through parts of the board of the picker, so that according to
the direction of reciprocation of the piston air is pumped from or sucked in through
these openings. (Figs. 1, 2, 3, 9.)
As the slide draws the cloth from the gluing cylinder the cam, 63, and lever, 62,
draws down the picker so the pins fasten into the boards, and at the same time the
cam, 76, and lever, 75, draws down the pump piston causing such a suction of air
along the bottom of the picker as to lift and hold one of the back linings. The
picker with this load is raised slightly to clear the guides, and then by the cam, 69,
and rack, 65, and segment, 64, is rotated one half of a revolution and the boards and
back lining deposited upon the glued. side of the cloth which has been drawn by
the slide, 23, over the platform, 79. (Figs. 1, 28, 29.) When in this position the
folders operate to lay the cloth over the edges of the boards and back linings.
In a hollow in the under side of the bars, 38 and 39, held by gibs, 81, are
slides, 80, that are reciprocated transversely of the machine by rocker arms, 82, ou
shaft, 83, that has an arm, 84, which is connected by a link, 85, with a lever, 86,
which is oscillated by the cam 87 on shaft 10, the upper ends of the arms, 82, being
connected by a rod, 88, that passes through lugs, 89, projecting from the bottom of
the slides. (Figs. 18, 19, 20, 21, 22.).
The gibs, 81, loosely hold the ends of folding plates, 90, that have pins, 191

page_text: projecting from their upper surface into slots, 192, cut diagonally in the slides, 80,
so that when the slides, 80, are reciprocated transversely of the machine the slots
and pins cause the folding plates, 90, to move edgewise toward or from each other.
(Figs. 22, 23, 24.)
In a hollow in the under side of the bars, 42 and 43, which are supported at a
lower level, held by gibs, 91, are slides, 92, that are reciprocated longitudinally of
the machine by levers, 93, on shaft 94 that is rocked by a lever, 95, which has a
roll running in a cam, 96, on shaft 10.
The upper ends of these levers, 93, are joined by a rod, 97, that passes through
lugs, 98, projecting from the bottom of the slides. (Figs. 18, 19, 20, 21, 22,
23, 24.)
The gibs, 91, loosely hold the ends of folding plates, 99, that have pins
projecting from their upper surface into diagonal slots in the slides, as described
in relation to the slides and plates supported by the transverse bars, so that when
the slides are reciprocated these folding plates move toward each other. (Figs. 21,
22, 23, 24.)
When the cam, 63, has caused the picker, 70, to force the boards, back lining
and cloth down through the opening between the transverse bars, and the edges of
the cloth stand up, (Fig. 30) the plates, 90, are moved toward each other and fold
the cloth over the end edges of the boards and back lining; then when the cam 63,
pulls the picker, 70, still lower and the other edges of the cloth stand up, the
plates, 99, are moved toward each other and fold the cloth over the side edges of
the boards.
In order to make a neat fold at the corners, to the bottom of the slides, 90, that make
the first fold of the cloth over the ends of the boards, there are adjustably attached
creasers or nickers, 100, that project slightly below the level of the folders, and
when the folding plates lay the cloth over the ends of the boards and back linings
these creasers travel along the side edges creasing the cloth and sticking it together
beyond the boards so that neat corners will be made when the second folders turn
the cloth over the side edges. (Figs. 22, 23, 30, 31.) These creasers are supported
by tongues, 101, that project into and move in mortises, 102, cut longitudinally in
the top of the lower bars, 42, 43, and they are connected with the folding plates, 90,
by tongues, 103, that move in mortises, 104, cut longitudinally in the bottom of the
plates. (Figs. 22, 23.) When the plates operate to fold the cloth the creasers
move with them, the tongues, 101, sliding freely in the mortises, 102, and when the
lower bars are moved for adjustment to conform to cases of different widths the
creasers move with them, the tongues, 103, moving in the mortises, 104.
In order to provide for the folding of the cloth over boards of varying widths
and lengths for cases of different sizes the folders must be adjustable, and the
board and back lining receptacles should be similarly adjustable. To accomplish
this the bars, 39, 40, are permanently attached at their ends to the sides of the
machine, the bar, 38, is loosely supported with its ends in grooves, 105, and bar 41
is similarly supported in grooves, 24, in the sides, (Figs. 25, 26) while the bars, 42, 43,
are movably supported below, at the front end by a transverse beam; 44, and near
the center by the cross wall, 45. The adjustment of these bars is accomplished by
means of screws aud this mechanism is shown in Figures 25 and 26. A rod, 107,
with a squared end for a handle or wrench, extends transversely of the machine at
the rear and bears near the sides gears, 108, that mesh with gears, 109, on rods, 110,
that extend longitudinally of the machine. These rods, 110, are provided with
right and left threads near the ends, on oue of which are threaded nuts, 111, secured
to the bar, 41, while on the other are threaded nuts, 112, attached to the bar, 38.
According to the direction in which the rod, 107, is turned the bars, 38, 41, move
in the slots in the frame toward or from the bars, 39, 40, to increase or diminish
the distance according to the length of the boards to be used in forming the cases.
A rod, 113, with a squared end for a handle or wrench, extends transversely
near the middle of the machine with right and left threads on which are nuts, 115,
projecting from near the middle of the bars, 42, 43. This rod, 113, has a gear, 114,

page_text: meshing with a gear, 116, on a rod, 118, that extends parallel with the side of the
frame, and bears a gear, 119, that meshes with a gear, 120, on the rod, 121, that
extends across the machine. This rod, 121, also has right and left threads on
which are nuts, 122, that project from the bottom of the front ends of the bars, 42, 43,
so that when the rod, 113, is rotated the bars, 42, 43, are moved toward or from
each other to adjust the space between them, according to the width of the boards
and back linings to be used in forming the cases. (Figs. 25, 26.)
The bars, 40, 41, are also connected with the bars, 42, 43, by the board and back
lining guides, 46, 47. Each of these guides has a tongue, 123, that projects into a
slot, 124, in the top of the transverse upper bars, and a tongue, 125, that projects
back of the lower edge of these bars so the guides are movable along the edge of
the upper bars, while the corner board guides, 46, are also movably held to the
edge of the lower bars, 42, 43, by projecting tongues, 126.
When the bars, 40, 41, are moved the corner guides slide freely along the edge
of the lower bars, 42, 43, and when the bars, 42, 43, are adjusted the corner guides
slide along the edges of the bars, 40, 41.
A rod, 127, with squared end, extending transversely of the machine, is provided
with right and left threads on which are nuts, 129, projecting from the center
board and back guides, 47, and has a gear, 128, that meshes with a gear, 130, on
rod 131 supported by the bars, 40, 41.. Keyed to the rod, 131, is a gear, 132, in
mesh with a gear, 133, on a rod, 134, supported by the bar, 41, and having right
and left threads on which are nuts, 129, projecting from the backs of the center
guides, 47, on the bar, 41.
When the rod, 127, is turned the center guides, 47, are drawn by the threads
and nuts toward or from each other to adjust them to the widths of the back
linings which are to be used by the machine in forming the cases.
The platform, 79, over which the glued cloth is drawn by the slide, 23, is borne
by a column, 135, held in the arms of a bracket, 136, supported by the cross
wall, 45. A spring, 137, normally holds this platform elevated, while a cam, 138,
on the shaft, 10, by contact with the arm, 139, projecting from the column, depresses
it at the proper time. (Figs. 28, 29.) After the second fold has taken place the
platform with the completed case is lowered to a position slightly below the
discharging slide, 140, which then moves and pushes the case from the machine
between the rollers, 150. This discharging slide is a plate provided with nuts, 141,
that freely move on rods, 142, secured transversely of the frame. To one of these
nuts is connected a cord that passes over a train of pulleys, 143, 144, 145, to a
sheave, 146, mounted upon a journal to which is secured a pinion, 147. In mesh
with this pinion is a segmental rack on a lever, 148, that bears a roll in contact
with a cam, 149, on shaft 10.
After a case is completed and the platform is below the discharging slide, the
cam, 149, oscillates the lever, 148, so the rack rotates the pinion and drives the
sheave, causing the cord to pull the slide and push a case between the rollers, 150.
The slide then returns to its normal position and the platform rises to receive
another cloth. (Figs. 28, 29.) The upper of the rollers, 150, is mounted in
stationary bearings, 151, while the lower is mounted in swinging bearings, 152, that
are held up by springs, 153, so as to press the cases as they are discharged between
the rolls with a yielding pressure. (Figs. 2, 29.) Both shafts of these rollers
bear intermeshing gears, 154, while the upper also bears a bevel gear, 155, that
meshes with. a bevel gear, 156, on a vertical shaft, 157, that has a gear, 158, in
mesh with a gear, 159, on the main driving shaft, 30. (Figs. 2. 3.)
The bars bearing the board and back lining holding guides and folding plates are
adjustable for forming cases of the desired size and shape, by simply turning the
adjusting screws. The cams on the cam shaft are so timed that the picker lifts
from the elevator a pair of boards and a back lining while the glue mechanism
glues the cloth and the slide draws it across the platform. The picker is then
rotated and depressed bringing the boards and back lining down upon the. glued
cloth and pressing them and the platform down between the bars, 38, 39, when the

page_text: first folding plates move and lay the cloth over the ends of the boards and back
lining, and the creasers prepare the corners. The picker then descends further,
pressing the platform with the cloth, boards and back linings between the bars 42, 43,
so the second folding plates may operate to fold the cloth over the side edges of the
boards, and after the platform descends a little further the discharging slide
pushes the completed cases from the platform to the rollers between which the
cases are pressed and hardened as they are discharged from the machine.
