Year: 1885

page_text: We CHARLES WATSON of Pickwood, Leek, in the County of Stafford; Silk Manu-
facturer and WILLIAM RODOLPHUS LANDFEAR, of 258 Madison Street, Brooklyn in
the State of New York, United States of North America, Machinist, do hereby
declare the nature of the said invention for "IMPROVEMENTS IN MACHINERY FOR
PRINTING SPOOLS OR BOBBINS," to be as follows:-
Our invention relates to improved machinery for printing upon both ends of
spools simultaneously the mechanism being capable of being readily adjusted to
suit various sizes of spools or bobbins and our invention consists in combinations
and arrangements of mechanism-namnely-The mechanism is carried on a frame
or stand in which there are bearings for a horizontal shaft, upon one overhanging
end of which there are fast and loose driving pulleys and a fly wheel.
On this first motion shaft there are two bevel wheels one of which gears with
another on a cross shaft at right angles to the first motion shaft which cross shaft
is in bearings in a headstock on the framing.
There is also a second cross shaft driven from the second bevel on the first
motion shaft which bevel wheel is movable on a fixed key to permit the headstock
to be adjusted on the bed of the frame to and from the other cross shaft, while
being kept parallel thereto, this adjustment being effected by a hand screw and
lock screw.
To each headstock an incline rail is secured, along which rails the spools are fed
to be printed, and they roll against and push each other forward down the
incline rails and there is an adjustable guide to prevent the spools from lifting
off the rails.
The lower ends of these rails are bent up vertically to form stops against which
the bobbin or spool comes, which is to be provided-These rails can be adjusted by
means of incline slots and are then secured to suit each size of spools and to bring
the centres of the spools opposite the printing arrangements, and one of these rails
is connected with the other by a stud so that both will be simultaneously adjusted
at the same time.
On one over-hanging end of each cross shaft the printing dies are mounted and
as the mechanism for both cross shafts is the same it will be only necessary to
describe that on one cross shaft.

page_text: The face of the printing die is engraved on the segment of a cylinder, as it
prints by rolling action and the die has a stem which is inserted and secured in a
block fixed on the overhanging end of the cross shaft.
The stem of the die has a hole through its axis for a sliding pin which is forced
outwards so that its end will project beyond the face of the die, by a spring, and is
drawn in when the die is being inked by a fixed cam which acts upon a bowl on a
stud projecting from the sliding pin.
The ends of the spools are guided by the angle rails between two side plates in
which slots or holes are formed to allow the pin and printing dies to pass through
and come against each end of the spool being printed.
Each time the cross shafts rotate they come in contact with a series of inking
and distributing rollers rotated by being geared with their respective cross shafts.
When the pins projecting from the dies come round, they simultaneously enter
the hole in the axis of the spool and lift it vertically, the printing dies rolling in
contact with the ends of the spool and printing at the same time, and when the
spool has been printed and lifted, the next spool to be printed comes under it.
Two levers jointed one on each side and each acted upon by a spring press
against the heads of the spool last printed and thus prevent it from falling, and
when the next spool is printed the one last printed is further lifted and allowed to
fall over the ends of the vertical part of the rails into any suitable receptacle.
Dated this twenty fifth day of August 1885.

facturer, and WILLIAM RODOLPHUS LANDFEAR of 258 Madison Street, Brooklyn, in
the State of New York United States of North America, Machinist, 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 relates to improved machinery for printing upon both ends of
spools simultaneously the mechanism being capable of being readily adjusted to
suit various sizes of spools or bobbins and our invention consists in combinations
and arrangements of mechanism namely-The mechanism is carried on a frame or
stand in which there are bearings for a horizontal shaft upon one overhanging end
of which there are fast and loose driving pulleys and a fly wheel.
On this first motion shaft there are two bevel wheels one of which gears with
another on a cross shaft at right angles to the first motion shaft which cross shaft
is in bearings in a headstock on the framing.
There is also a second cross shaft driven from the second bevel on the first
motion shaft which bevel wheel is movable on a fixed key to permit the headstock
to be adjusted on the bed of the frame to and from the other cross shaft, while
being kept parallel thereto, this adjustment being effected by a hand screw and
lock screw..
•
To each headstock an in incline rail is secured along which rails the spools are
fed to be printed, and they roll against and push each other forward down the
incline rails, and there is an adjustable guide to prevent the spools from lifting
off the rails.
The lower ends of these rails are bent up vertically to form stops against which
the bobbin or spool comes, which is to be printed These rails can be adjusted by
means of incline slots and are then secured to suit each sizo of spools and to bring
the centres of the spools opposite the printing arrangements and one of these rails
is connected with the other by a stud so that both will be simultaneously adjusted
at the same time.
On one overhanging end of each cross shaft the printing dies are mounted and as
the mechanism for both cross shafts is the same it will be only necessary to
describe that on one cross shaft.
The face of the printing die is engraved on the segment of a cylinder, as it
prints by rolling action, and the die has a stem which is inserted and secured in a
block fixed on the overhanging end of the cross shaft.
The stern of the die has a hole through its axis for a sliding pin which is forced
outwards so that its end will project beyond the face of the die, by a spring and is
drawn in when the die is being inked by a fixed cam which acts upon a bowl on a
stud projecting from the sliding pin.
.
The ends of the spools are guided by the angle rails between two side plates in
which slots or holes are formed to allow the pin and printing dies to pass through
and come against each end of the spool being printed.

page_text: Each time the cross shafts rotate they come in contact with a series of inking
and distributing rollers rotated by being geared with their respective cross shafts.
When the pins projecting from the dies come round they simultaneously enter
the hole in the axis of the spool and lift it vertically the printing dies rolling in
contact with the ends of the spool and printing at the same time and when the
spool has been printed and lifted, the next spool to be printed comes under it.
Two levers jointed one on each side and each acted upon by a spring, press
against the heads of the spool last printed and thus prevent it from falling, and
when the next spool is printed the one last printed is further lifted and allowed to
fall over the ends of the vertical part of the rails into any suitable receptacle.

invention.
"
a is the bed or frame of the machine carried on stands or legs a¹
b is the first motion shaft which has its bearings in the headstocks c and c*, one
of which is or may be secured to, and the other adjustable upon the bed a.
On one end of the first motion shaft b is a pulley 6' for the driving belt, which
also, acts as a fly wheel.
..
The shaft b has two bevel wheels 6' and 63 upon it each bevel gears with another
on cross shafts having bearings in the headstocks.
The bevel 3 on the shaft b for the adjustable headstock is connected with the
shaft, by a key and key groove so as to move with the headstock c* and keep in
gear with the bevel 6* on the cross shaft when being adjusted, as shown.
Each headstock c and c* carries all the parts required for printing upon one head
of the bobbin, and the connected parts for the feeding and delivery of the bobbins
or spools when printed upon, so that from a description of the parts upon one
headstock the corresponding parts on the other headstock will be readily under-
stood.
The headstock c which is fixed, is that nearest to the driving pulley 6¹ the other
headstock c* is arranged so as to be adjustable in the lengthway of the bed a by a
hand screw a which has its bearings in a bracket a secured to the end of the
bed a which screw, screws into the headstock or into a nut fitted in the head-
stock which is or can be clamped by the handle c¹ passing through a slot in the
headstock and screwing into a hole in the bed a.
Each headstock has a diagonal rail c² attached to, it, and to the side of each
rail there is another rail c³ secured by screws passing through slots at an angle
of 45° degrees to the vertical the upper side of these rails c³ forming a ledge and
incline upon which the heads of the bobbins roll when descending the incline by
gravity.
It will be understood that the heads of the spools or bobbins at one end rest
upon the rail c³ on one side, and those at the other end of the bobbin rest upon
the rail c on the other side.
There is a trough c of sheet metal placed or secured at and between the rails c³
at the higher end of the incline upon which the spools to be printed upon are
placed so as to roll by gravity down the inclined rails in succession one bobbin or
spool coming against and pressing forward the one before it.
In a bracket c secured to the diagonal rail c³ of the fixed headstock c the end of
a rod c is secured by a set screw c so as to be adjustable-The end of this rod c
is bent at a right angle to the long part of the rod, and is held so that the long
part of the rod will be parallel to the diagonal rails or incline.
The object of this rod is to prevent the spools when passing down the incline
from lifting and getting out of their places, as its lower edge comes nearly close to
the barrel part of the spools or bobbins, and it can be adjusted higher or lower
according to the size or diameters of the spools or bobbins.
The adjustable rails c³ on which the heads of the spools or bobbins roll and are
carried have each a vertical part or projection c³ at their lower ends, which act as a
stop to prevent the lowest spool or bobbin from descending further and hold it in

page_text: These rails c have to be adjusted for
ach different diameter of the heads of the spools or bobbins to be operated upon
nd the diagonal slots (not seen) admit of this adjustment, as they give both a
ertical and horizontal adjustment at the same time to bring the axis of the spool
r bobbin into the position required opposite the pins and printing dies hereinafter
entioned.
he correct position for being printed upon.
One end of a stud c° see fig. 1 is secured in the vertical part of one adjustable
ail c on the fast headstock so as to fit and slide freely through a hole in the
ertical part of the other rail c8 so that when one is adjusted the other will be also
djusted, and the stud c thus keeps up the connection between the rails c³ not-
vithstanding the adjustment of the movable headstock cx to suit the different
engths of spools to be operated upon.
On the end of each cross shaft there is a boss & which has a hole in it at a right
ngle to the axis of the cross shaft, and in this hole on a stem or otherwise a die or
printing surface e is secured the face of which die forms the segment of a cylinder
of the diameter in which the face of the die rotates. There is a hole in the centre
of the die e at a right angle to the axis of the cross shaft in which hole a pin dis
fitted to slide so that one end can be pushed out beyond the face of the die e and
then withdrawn-This pin d' is acted upon by a helical spring surrounding it in
the hole in the boss d and there is a stud d' inserted in it at a right angle that
comes through a slot in the outer end of the boss & the slot being in a line with
the sliding pin d¹. The outer end of the stud d' has a bowl upon it which works
against a cam surface d³ (see fig. 1) formed in a hole in a plate d* secured to the
headstock.
The cam surface d³ withdraws the end of the pin d' when the die or printing
surface e is passing the inking rollers, and allows it to project beyond the printing
surface (e) when the latter is about to operate upon the head of the spool as the
end of the pin d first enters the hole in the axis of the spool or bobbin, and brings
it central with the die e, and thus (the two ends of the spool being acted upon
simultaneously and in like manner) the spool or bobbin is lifted vertically by the
rotary motion of the printing die and pins allowing another spool or bobbin to
take its place ready to be operated upon at the next rotation of the printing dies.
When the printed spool or bobbin has been lifted high enough it has come
against and will push back the ends of levers fhaving their fulcrums at f¹ acted
upon by springs f2 so that when the heads of the spools or bobbins are clear of the
upper edge c¹ of the vertical stops c³ the springs cause the levers f to throw the
spools or bobbins forward and they then fall into any suitable receptacle.
The boss d on each cross shaft has a spur wheel do on it which gears with an
intermediate spur wheel do on a stud that drives a wheel on the inking roller d' on
a stud on the face of the headstock which receives ink by working in contact with
a roller ds on a stud in the headstock and which latter roller receives ink from a
box de hinged on a stud d* and upon which a lid d" is also hinged.
The last named roller d³ has a ratchet wheel at one end which is turned
intermittently by a pawl g having its fulcrum pin g¹ on a lever g² centred on a
stud g³ in the face of the beadstock the end of the lever gs being acted upon by a
cam surface on the side of the spur wheel d³ which drives the inking rollers or by
a bowl g' on a stud in the face of the wheel d³.
There is an adjusting screw g' the end of which acts upon the underside of the
ink box do and thus regulates the space for ink to pass through between the
bottom of the box and the ink carrying roller d³.
There are also one or more ink distributing rollers g each of which rotates on a
stud in the headstock and work in contact with the inking roller d' which has a
cam incline at one end to come against a pin g³ on the end of the stud, against
which pin it is forced by a spring secured to a stud 96 on the headstock so that in
rotating the inking roller has end motion to distribute the ink, the cam pushing
the roller endways one way and the spring the other way.
