Year: 1860

page_text: LETTERS PATENT to George Moulton, of Manchester, in the County of
Lancaster, Engineer, for the Invention of "IMPROVEMENTS IN MACHINERY
FOR TRANSFERRING TO OR TRACING UPON PRINTING ROLLERS OR CYLINDERS
COPIES OF DESIGNS OR PATTERNS INTENDED TO BE ETCHED OR ENGRAVED
THEREON."
PROVISIONAL SPECIFICATION left by the said George Moulton at the
Office of the Commissioners of Patents, with his Petition, on the 22nd
May 1860.
I, GEORGE MOULTON, of Manchester, in the County of Lancaster, Engineer,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY FOR TRANSFERRING TO OR TRACING UPON PRINTING ROLLERS OR
CYLINDERS COPIES OF DESIGNS OR PATTERNS INTENDED TO BE ETCHED OR ENGRAVED
THEREON," to be as follows:-
My said Invention has reference to the parts of the aforesaid machinery
which carry the diamonds or cutting points by which the copies of the
proposed design are traced upon the surface of the roller.
The object of the Invention is to combine in the same instruments, or parts
of the machinery, facilities for enabling the diamonds or cutting points to

page_text: operate over extended portions of the roller, with convenient means for
accurately adjusting each diamond or cutting point in the precise position
upon the carrying arm which it is required to occupy. The Invention consists
in the arrangement and combination of the parts of the apparatus for carrying
the diamonds or cutting points, so that each diamond or cutting point can be
applied at any part of a considerable section of the roller by the use of a
curved arm or bar for carrying the diamond bolt or holder, and at the same
time the accurate adjustment of the diamond bolt or holder on the carrying
arm or bar can be effected with greater ease and precision than heretofore.
The diamond bolt or holder is adjustable by being slided along the curved
carrying arm by the action of a screw (or of a rack and pinion) acting upon a
pin or nutt attached to or forming part of the said bolt or holder, and when
adjusted is retained in position by a clamping screw.
The essential characteristic of the Invention is, the combination of the
screw or rack-and-pinion adjustment with the curved carrying arm or bar.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Moulton in the Great Seal Patent Office on the 21st
November 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
MOULTON, of Manchester, in the County of Lancaster, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of May, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-third year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
George Moulton, Her special licence that I, the said George Moulton, my
executors, administrators, and assigns, or such others as I, the said George
Moulton, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time, and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN MACHINERY
FOR TRANSFERRING TO OR TRACING UPON PRINTING ROLLERS OR CYLINDERS COPIES
OF DESIGNS OR PATTERNS INTENDED TO BE ETCHED OR ENGRAVED THEREON," upon
the condition (amongst others) that I, the said George Moulton, my executors
or administrators, by an instrument in writing under my, or their, or one of

page_text: their hands and seals, should particularly describe and ascertain the nature of
the said Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said George Moulton, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement, and the Drawings hereunto annexed :-
The machines to which my said Invention is applicable are those used by
the engravers of rollers for calico printing, for transferring multiplied copies
or repetitions of devices, patterns, or designs to the surfaces of rollers or
cylinders, mills or dies, upon which the same are to be etched, by scratching
or indenting the lines of such copies at many points simultaneously in a
varnish or etching ground with which the rollers have been previously coated.
The Invention consists in the manner of constructing, arranging, and com-
bining those parts of such machines which carry the diamonds or cutting points,
the object thereof being to afford convenient means for accurately and readily
adjusting the diamonds or cutting points in their respective working positions,
as well as increased facilities for enabling them to operate over extended
ranges or sections of roller surface. The means to which I have recourse for
these purposes are the use of curved or jointed levers or arms for carrying the
diamond bolts or holders, and the application to the latter, or to the diamond
bits, of screw, rack and pinion, or eccentric adjustments, of the nature herein-
after to be more particularly pointed out.
These said adjustments, as well as the arrangements, combinations, and
other matters which constitute my said improvements, I propose to explain by
means of the Figures or Diagrams contained in the two Sheets of Drawings
hereunto attached, and which Figures represent plans, elevations, and sections
of several modifications of my improved arrangements. The parts of the
various Figures are referred to by means of alphabetical and numerical
characters marked thereon, and to avoid prolixity and unnecessary repetition,
the same or similar parts which are common to or recur in several Figures
are referred to one common explanation or description by the same character
or characters repeated as often as necessary.
Figures 1, 2, 3, 4, and 5, Sheet 1, explain a mode of effecting the final
adjustment of the diamond, applicable in conjunction with curved slotted
levers or carrying arms of ordinary construction.

page_text: Figure 1 is a plan view, and Figure 2, a profile or side view of a curved
slotted lever or arm with the tool holder or diamond bolt applied thereto;
Figure 3 is an end view of the diamond bolt projected upon a vertical plane,
intersecting the lever transversely at the dotted line 1*. 2*, Figure 2;
Figure 4 is a transverse vertical section of the same, at the dotted line
3*... 4*, Figure 2; and Figure 5, a longitudinal vertical section at the
dotted line 5*. . . . 6*, Figure 1.
A represents the lever or carrying arm, and A' (Figure 1), the slot in the
curved end thereof. a is the diamond bit; it is inserted into an adjustable
block a, the tail of which passes through the slot A'; b is a frame, which also
passes through the slot A', and forms a receptacle for the adjustable block a,
the latter being furnished with wings or projecting flanches a', a', (Figure 4,)
which abut against the overhanging upper sides or edges of the former; c is a
clip, which passes transversely through the frame b, and partially embraces
the outer and under sides of the lever A; d is a finger screw working through
a corresponding internal screw in the lower part of the frame b, its extremity
being turned down and inserted into a hole in the lower part of the clip c,
against the edge of which hole the shoulder which terminates the screwed
part abuts. When the holder has been brought proximately into its intended
position, the frame b is drawn downwards, and the clip c forced upwards by
the one operation of turning the screw d, and the two parts of the tool holder
are thereby closely compressed upon the lever A, and firmly retained in the
position which they have been made to occupy. The final adjustment of the
diamond is now effected by moving the adjustable block a in the proper direction
by means of the screw a², which passes through a hole in the adjustable
block a tapped with a corresponding internal thread. The diamond bit being
thus accurately adjusted, the adjustable block a is fastened by having its
projecting flanches a', a', forced against the adjacent overhanging edges of the
top of the frame b, by means of a second finger screw a', which works in a
corresponding internal screw through the before-mentioned finger screw d, and
the screw a being secured by its lock nutt a³, the adjustment of the diamond
in its proposed working position is completed.
Figures 6, 7, 8, 9, 10, and 11, Sheet 1, explain a mode of effecting the
adjustment of the diamond bit similar to the foregoing, except in being
adapted to a carrying arm or lever with a solid end. Figure 6 is a plan view,
and Figure 7 a profile of the working end of the lever; Figure 8 is an end
view of the tool holder, projected at a plane intersecting the lever vertically
and transversely at the dotted line 7*. . . 8*, Figure 7; Figure 9 is a trans-

page_text: verse vertical section of the same at the dotted line 9... 10*, Figure 7;
Figure 10 is a view, partly in section and partly in profile, projected at a
vertical plane along the dotted line 11*... 12*, Figure 6; and Figure 11 is
a longitudinal vertical section along the dotted line 13*... 14*, Figure 6.
In this arrangement B is the working end of the solid lever; e is the frame
which receives the adjustable block f; it encloses the lever B, and is furnished
at one side with two projecting lugs e¹, el. The frame e is slided to and fro
along the lever B until the diamond which it carries is proximately adjusted
to its working point, whereupon it is clamped fast to the lever by the finger
screw is the adjustable block, which carries the diamond bit; it is
contained within the frame e, and is furcated downwards, so as to clasp the
lever B upon which it slides, for the purpose of finally adjusting the diamond.
The block fis furnished with one lateral lug f projecting between and in a
line with the lugs e, e¹, of the frame e. The adjustment of the block f (and
therewith of the diamond) is effected by turning the screw f, which passes
through holes in the lugs e¹, e¹, and works in a corresponding internal screw
within the lug f, being secured endwise by a lock nutt f³. When the block f
has been finally adjusted, it is fixed by being clamped against the top of the
frame e by means of the nutt f, which fits a screw formed to receive it upon
the upper projecting end of the block f, in which projecting end the diamond
bit is also inserted.
Figures 12, 13, 14, 15, and 16, Sheet 1, explain the construction of a
diamond bolt or tool holder, adapted for use in conjunction with a curved
slotted lever, and furnished with means for effecting the accurate adjustment
(endwise) of the diamond. Figure 12 is a profile or side view; Figure 13
an end view, or one transverse to the last mentioned; Figure 14 is a vertical
longitudinal section through the middle or at the dotted line 15*... 16,
Figure 13; Figure 15 is a vertical transverse section through the middle or
at the dotted line 17*... 18*, Figure 12; Figure 16 is a plan view. The
diamond bolt is of the usual form, and is represented at C; it passes through
the slot of the lever, and when approximately adjusted is clamped thereto by
the finger nutt C¹. The diamond bit is screwed into a horizontal bar h, which
occupies a longitudinal mortice or slot in the bolt, its extremities projecting in
both directions. To accommodate the movements of the diamond bit an
oblong slot or opening (seen in Figure 16) is made in the head of the bolt,
and communicates with the mortice or slot occupied by the bar h. Through
this oblong slot the diamond bit projects. The projecting extremities or arms
of the bar h are screwed and fitted with nutts h', h¹, by turning which the bar

page_text: can be slowly moved endwise, so as to alter the position of the diamond bit. By
this means the latter is capable of being adjusted with great nicety, and when
so adjusted is firmly fixed by tightening up the nutts h¹, h', against each other.
...
Figures 17, 18, 19, 20, 21, 22, and 23, Sheet 1, explain the construction of
a diamond bolt or tool holder adapted for use with a slotted curved lever and
with which is combined a means of accurately adjusting the diamond after the
diamond bolt has been proximately adjusted, which is a modification of that
lastly described. Figure 17 is a profile or side view of the instrument; Figure
18 an end view; Figure 19 is a vertical longitudinal section at the line
19* 20 in Figure 18; Figure 20 is a vertical transverse section
at the line 21*
22 in Figure 17%; Figure 21 is a plan view;
Figure 22 is a horizontal section at the line 23*... 24 in Figure 17, and
Figure 23 is a horizontal section at the dotted line 25* 26* in Figure
18. In this arrangement the adjustment of the diamond is effected by
means of a small horizontal sliding bar or plate, which moves endwise in
a direction transverse to that of the lever and of the motion of the dia-
mond bit, the changes in the position of the latter resulting from the
oblique force or pressure exerted against it by an inclined plane carried
by the horizontal adjusting bar. The diamond bolt C, and clamping nutt
Care applied in the usual manner for effecting the proximate adjust-
ment of the diamond. The diamond bit a occupies a rectangular cavity
or mortice g in the head of the diamond bolt, and its foot is screwed into a
guide plate i (Figures 19 and 23,) which slides in a horizontal mortice or slot
perforated lengthways through the diamond bolt. k is the adjusting bar
consisting of a middle part which is expanded in the form of a rectangular
plate and of two screwed arms extending therefrom in opposite directions and
protuding from the sides of the diamond bolt. The bark slides in a mortice
or slot formed in the diamond bolt transversely to the mortice of the guide
plate i. In the middle or expanded part of the bar k is a rectangular oblong
slot or aperture ¹ (Figure 22,) oblique to the directions of the motions of the
guide plate i, and of the adjusting bar k. Through this oblong aperture the
diamond bite is made to pass, and it will be perceived that any movement of
the adjusting bark will by the pressure of the sides of the slot or oblong aperture
against the diamond bit cause the latter together with the guide plate i
to change its position. *,, are adjusting nutts upon the screwed extremi-
ties or arms of the bar k which serve both to regulate the position of the bar
and to lock or fasten it when properly adjusted. The diamond bit is adjusted
by manipulating these nutts so as to slide the bar k in the direction adapted

page_text: for effecting the required alteration in the position of the diamond, and when
adjusted the diamond bit is fastened by tightening the nutts k², k, until they
lock each other.

Figures 24, 25, 26, 27, 28, and 29, Sheet 1, explain the construction of a
diamond belt or tool holder applicable to a slotted lever, and combined with
means for adjusting the diamond by means of an eccentric. Figure 24 is a pro-
file or side view of the diamond bolt so improved; Figure 25 is an end view;
Figure 26 is a longitudinal vertical section at the dotted line 27*... 28*,
Figure 25; Figure 27 is a transverse vertical section at the dotted line 29*
30, Figure 24; Figure 28 is a plan view with the diamond bit and fas-
tening nutt removed; Figure 29 is a horizontal section at the dotted line
31*... 32*, Figure 25. The diamond bolt C is approximately set in the slot
of the lever and fastened in the usual manner by the clamping screw C¹; a
dovetail groove traverses longitudinally the head of the diamond bolt, and is
occupied by a moveable slide 1, into which the diamond bit a is screwed;
midway in the under side of the slide is a small transverse groove l¹
(Figure 27). m is a small shaft or bolt, which extends vertically from the
under side of the slide downwards through the centre of the diamond bolt;
its head has a small lateral projection extending into a circular cavity con-
centric with the axis of the bolt or shaft m, and large enough to permit the
enlarged head of the bolt to turn in any direction. From the enlarged side of
the head of the bolt m springs a small eccentric pin m³, which enters the small
transverse groove in the under side of the slide 7, so that the revolution of
the eccentric pin m¹ round the centre or axis of the bolt m will necessarily
impart to the slide la rectilinear motion in its guiding groove through a space
equal to the diameter of the orbit of the eccentric pin. Hence the position of
the diamond carried by the slide 7 will depend upon the position into which
the bolt m may be turned. For the purpose of turning the latter it is furnished
with a fast milled head m², secured by a small screw. The diamond is suc-
cessfully and easily adjusted by turning the bolt m by means of its milled head
m²; the slide is then secured in its position by the pinching screw 1,
provided for that purpose.
Figures 30, 31, 32, and 33, Sheet 1, explain a manner of combining a solid
curved lever and a diamond bolt, with improved means of proximate and final
adjustment. Figure 30 is å side view or profile of the diamond bolt or tool
holder, with a fragment of the curved lever to which it is applied; Figure 31
is a plan of the same; Figure 32 is an end view of the diamond bolt; and
Figure 33 is a vertical transverse section at the dotted line 33*
34* in

page_text: Figure 30. B is the curved end of the lever; n is a box or frame, through one
side of which passes longitudinally a horizontal mortice hole or slot n', which
fits the lever or arm B, while through the other side is an oblong vertical mor-
tice hole or slot n² (Figure 31), of dimensions adapted for the reception of the
diamond bolt C, with liberty for the same to slide endwise within moderate
limits; n³ is a set screw which clamps the box n securely to the lever; by
slackening the screw n³ the frame n is released and becomes moveable along
the lever until the diamond is proximately set to the required point. The
diamond bit x is screwed into the head of the diamond bolt C in the
usual manner. The tail of the diamond bolt passes downwards through
the mortice n. n is an adjusting screw, which works in an internal screw n
(Figure 33) in the diamond bolt, so that the position of the latter in the mor-
tice can be altered by turning the former, which is restrained from moving
endwise by a collar upon its neck and a fast head or nutt. When the diamond
bolt has been approximately set by sliding the box or frame n upon the lever
and clamping it thereto the final adjustment of the diamond is accomplished
by turning the screw n¹ in the proper direction, and the diamond bolt, when so
adjusted, is locked by turning a set screw n6, which is tapped into it from
beneath for that purpose. n' is a washer interposed between the head of the
screw n and the bottom of the box or frame n.
Figures 34, 35, 36, 37, and 38, Sheet 1, explain the construction and com-
bination of the parts of an improved curved lever and diamond bolt provided
with means of adjusting the diamond in both directions. Figure 34 is a profile
or side view of the operating end and middle part of the improved lever and
its adjuncts; Figure 35 is a plan view of the same; Figure 36 is a view of
the under side, shewing more especially the manner of adjusting the diamond
laterally; Figure 37 is a longitudinal vertical section along the dotted line
35... 36 in Figure 35, with the adjusting screw in profile; Figure 38 is
a vertical transverse section through the fulcrum of the lever at the dotted line
35** 36**, Figure 35, shewing the sectional form of the guide feather
on which the weight slides. D is the weight with which the lever A is fur-
nished, for the purpose of applying pressure to the diamond; D' is a set screw,
which fastens the weight D by pressing down a die D'. My improvement in
the lever has reference to the manner of applying the weight D to the lever,
so that the said weight can be applied at either side of or directly over the
fulcrum of the lever. The weight is attached by means of the dovetail guide
rib or feather o on the upper side of the lever, which fits a dovetail groove in
the under side of the weight D. The section of the guide rib or feather o

page_text: appears in Figure 38. The improvement in the manner of applying the weight
consists in making the guide rib or feather o to extend continuously over and
on both sides of the fulcrum of the lever, so that the weight can be slided
from one arm of the lever to the other without impediment. By this altera-
tion the same lever is made applicable either to the upper or lower surface of
the roller under process by the mere alteration of the positions of the weight
and diamond bolt. The diamond bolt C passes through the slot A¹ of the
curved end of the lever, and is secured therein by the finger nutt C. The sides
of the bolt head terminate downwards in shoulders which bed upon the surface
of the lever on each side of the slot A', so that the tightening of the finger
nutt C causes the axis of the bolt to be directed towards the centre of the
curve of the lever. Through the body of the bolt is a longitudinal perforation
p, for the adjusting screw p¹ to pass through; a pin or swivel joint p² (Figure
37) passes transversely through the bolt, crossing the perforation p; it turns or
swivels freely in its bearings, and is pierced with a screwed hole adapted to
receive the adjusting screw p¹, which is furnished at its inner end with a milled
head p, by which it can be turned. The neck of the screw p¹ works in a
swivel pin p', inserted through the lever and turning freely in its bearings.
The screw p¹ is restrained from endwise motion by a collar p* in one direction,
and by the milled head p³ in the other. The slot A¹ in the lever is enlarged
at the inner end to admit the milled head p³ of the screw p', and the swivel pin
p in the diamond bolt C bearing the relation of a nutt to the adjusting screw
p', the turning of the latter forces the diamond bolt to traverse the slot A. The
swivel pins på, p, accommodate themselves to all changes in position under-
gone by the diamond bolt and adjusting screw. The adjustment of the diamond
backward and forward or in the direction of the lever is effected by slackening
the milled nutt C, turning the adjusting screw p¹ until the bolt is approxi-
mately adjusted, then tightening the milled nutt C¹ and correcting any aberra-.
tion in the diamond by again turning the adjusting screw p³, until the diamond
is brought accurately to the required point. The lateral adjustment of the
diamond is effected by means of finger screws q, q, acting upon the tail or
tongue of the saddle q¹. The saddle is pivoted upon conical pins or points in
the carrying bar, which enter the small holes 93, 9, in the under side of the
saddle (see Figure 36). The saddle is attached to the lever by the joint screw
9, which permits the angle of the lever with the tail of the saddle to be varied
by turning the finger screws q, q, which work through the lugs 9', q', in oppo-
site directions, and compress between them the tail of the saddle g¹. By
turning these screws, a slight variation in the direction of the lever is easily

page_text: effected for the purpose of adjusting the diamond laterally. This method of
lateral adjustment is not new, and does not form any part of my Invention,
except in so far as it constitutes one of the elements of the combination which
has now been described.
Figures 39, 40, 41, 42, 43 and 44, Sheet 1, explain the construction and
combination of the parts of a curved lever with its diamond bolt, in which the
necessary adjustments are effected by the operations of a rack and pinion as an
equivalent for a screw. Figure 39 is a profile or side view of the curved end of
the lever with its diamond bolt; Figure 40 is a longitudinal vertical section
along the dotted line 41*... 42*, (Figure 41) presenting an edge view of the
rack. Figure 41 is a view of the under side of the lever; Figure 42 is a
horizontal section along the dotted line 37*... 38*, Figure 39, or the dotted
line 39*... 40*, Figure 40; Figure 43 is an end view of the diamond bolt-
and end of the lever projected on a vertical plane intersecting the lever trans-
versely at the dotted line 45*. . . 46%, Figure 39; Figure 44 is a vertical
transverse section at the dotted line 43*. . . 44*, Figure 39. The diamond
bolt C slides in the slot A¹ of the lever A, and is fastened by its finger nutt C'
in the usual manner. r is a rack sunk into a recess in one side of the lever
with the teeth presented towards the slot; r is a slip of metal covering and
enclosing the rack and securing it in its place. A hole is drilled vertically
through the tail of the diamond bolt between the centre thereof and that side
of it which is nearest to the rack, in which hole is inserted a small shaft or
spindle 2 (Figures 42 and 44) carrying at its upper end a pinion, which gears
with the rack r, and at its lower extremity a milled head or fast finger nutt r
for turning the pinion. By the last-mentioned operation the diamond bolt is
moved along the slot of the lever until the diamond is adjusted to the required
point, the diamond bolt being fastened by the finger nutt C'. Although the
arrangement here shewn is that which I prefer, the rack is not necessarily
applied in the side of the slot, but may be affixed to the upper or under side
of the lever or in the middle of the slot (passing through the centre of the
diamond bolt). It is also evident that this means of adjustment is applicable
with slight modifications to a solid lever.
Figures 45, 46, 47, 48, 49, 50, 51, 52 and 53, explain the construction and
arrangement of a compound lever for applying and adjusting the diamond bolt,
the operating arm of the said lever consisting of two straight arms or bars
jointed together in such a manner as to be easily set and retained at any
required angle with each other so as to constitute what may be termed a
flexible bar or a curved bar with a variable curvature. Figure 45 is a side

page_text: view or profile of this arm; Figure 46 is a plan; Figure 47 is a vertical
longitudinal section along the dotted line 47*... 48* in Figure 46; Figuro
48 is a like section along the dotted line 49*... 50* in Figure 46; Figure 49
is an end view; Figure 50 is a transverse vertical section at the dotted
line 51... 52* in Figure 46; Figure 51 is a like section at the dotted
line 53*... 54* in Figure 46; Figure 52 is a like section at the dotted.
line 55*... 56* in Figure 46; and Figure 53 is an end view as seen from
the direction of the fulcrum projected on a vertical plane intersecting the
lever at the dotted line 47*. . . 48*. s is the operating end or arm of a
lever, the opposite arm and fulcrum of which may be constructed according
to the manner shewn in Figures 34 and 35, or in any other approved manner.
In a slot & slides the tenon of a carriage t. The latter is perforated length-
wise by an inside or female screw through which works a small screwed
shafts, the neck of which passes through an open slot in the end of the
lever and is restrained from endwise movement by a small collar and by
the milled head, by the latter of which the screw is manipulated in setting
the carriage t. When the carriage has been brought into the required position
by the screws, it is fastened by means of the clamping nutt t¹. The upper
part of the carriage t has two vertical wings t², t, through which passes a
joint pin t³, upon which the boss u¹ of the second or bolt arm or lever u is
hinged. The bolt lever u has a slot in which the diamond bolt u² slides,
its rectilineal direction and perpendicularity being preserved by beads or
flanches, 3, (Figure 50) which move in corresponding grooves in the
sides of the slot. u is the adjusting screw of the diamond bolt, and w³ the
5 milled head or fast nutt by which the same is turned for the purpose of setting
or adjusting the diamond bolt. The latter when proximately set is clamped
The lever u is adjusted to the proper angle with the lever s,
by means of the finger screws t', to. These pass through screwed holes in
the carriage t, and work the former against the under surface of the lever u,
o the latter against a tail or arm w projecting from the boss of the lever u.
These screws act against each other so that by turning them in contrary
directions the angle which the lever or arm u makes with the lever or arm s
can be varied as required, and by tightening both the screws the relative
positions of the arms. is.maintained. By the means now described it will be
seen that the diamond can be proximately and finally adjusted to any part
of the surface of the roller, which lies beyond the lines in which the roller
would be cut by a vertical plane passing through its axis and within the
compass or reach of the arms or levers, and that either from above or from
by the nutt u.

page_text: below the roller. The lever u being capable of a position parallel to any
tangent to the curve of the roller possesses as perfect an adaptation to the
purpose in view as a curved lever, with the further advantage of being appli-
cable to rollers of various sizes. The slotted form is most convenient for levers
of this description, but it is evident that the principle is equally applicable to
solid levers. The combination of parts in the lastly before described com-
pound lever may be reduced to a more simple form, by leaving out the hinge
joint and the screws t, to, making the bolt bar or arm u adjustable only by
sliding in the slot s¹ of the lever arm s, at a suitable but invariable angle with
the latter. In this case I make the bolt bar or arm u curved, and dispense
with the adjusting screw u', using a simple diamond bolt of ordinary con-
struction. The bolt bar or arm u is rigidly attached to or formed in one piece
with the carriage or sliding piece t. The proximate adjustment of the
diamond bolt is in this case effected by setting it in the slot of the sliding
bolt bar u and its final adjustment by the action of the screw & upon the
latter. It will be seen that this arrangement is merely a variation of that
described by Figures 34, 35, 36, 37 and 38, a stationary adjusting screw being
substituted for one mounted in swivel joints.
Figures 54, 55, 56 and 57, Sheet 2, explain the construction and combi-
nation of the part of a curved slotted lever and diamond bolt provided with
means for adjusting the diamond both laterally and endwise by means of
screws. Figure 54 is a profile or side view of the operating end of the lever
and of the diamond bolt with their appurtenances; Figure 55 is a plan;
Figure 56 is a section of the lever along the dotted line 59*... 60* in
Figure 55 with the adjusting shaft or screw and diamond bolt in profile;
Figure 57 is a section along the dotted line 61*. . . 62*, in Figure 55, the
diamond bolt being shewn in a different situation. In this arrangement the
adjustment of the diamond bolt in the direction of the length of the lever
is effected through the agency of the rod v, the screwed end of which passes
through and is propelled by the rotatory finger nutt v³. A neck between the
head and collar of the nutt works in an eye or opening through a pin or
pivot, which swivels in the end of the lever A, so that the nutt is restrained
from motion endwise but accommodates itself to all changes in the position of
the rod v. A small nutt on the end of the screwed part prevents the rod
from being drawn too far in or out. The plain part of the rod is embraced
by a pair of dies v¹ fitted transversely into the body of the diamond bolt C, and
crossing a mortice or longitudinal opening therein 2, Figure 57. The dies
swivel in their bearings so as to adapt themselves to the positions of the rod v,

page_text: and diamond bolt C for the time being. They are compressed so as to grip
tightly the rod vby a finger screw v°, which is tapped vertically into the tail
of the diamond bolt and the point of which impinges upon the lower die.
To adjust the position of the diamond bolt in the slot A', it is first set'ap-
proximately to the required point, and then screwed fast to the rod v, by
turning the finger screw ³, so as to compress the dies upon the rod. The
diamond is then finally adjusted by turning the finger nutt v³ so as to move
the rod vendwise in the required direction. When adjusted the diamond bolt
is clamped by its finger nutt C¹.
The lateral adjustment of the diamond is effected by altering the position of
the diamond bit in a manner similar to that herein-before described, as a
means of endwise adjustment in connection with Figures 12, 13, 14, 15,
and 16. The foot of the diamond bolt a passes downwards through a trans-
verse oblong slot in the head of the diamond bolt, and is screwed into the flat
expanded centre of an adjusting bar w, which slides in a transverse horizontal
mortice or opening in the bolt head. The arms of the adjusting bar are
round, and fitted with finger screws w¹, w¹. One of these is left out in
Figures 54 and 56 to expose the opening of the mortice. These screws act
against the sides of the diamond bolt and against each other, so as to draw the
adjusting bar in either direction to adjust the diamond bit to any part of the
oblong slot in the bolt head, and to secure it there by being locked by one
another.
In the machines to which the improvements herein-before described are
applicable, the movements of the diamonds, to the accurate adjustment of
which this Invention has reference, are governed (as is well known) by those
of a tracer, which is drawn over the lines of a figure or figures delineated on
a pattern plate, which latter is temporarily secured upon a concave bed, the
curvature of whose surface is concentric with the roller to which the copies of
the figures or designs are to be transferred. In order that the largest amount
of benefit may be derived from my improved adjustments it is desirable that
the pattern plate should bed as evenly as possible upon the concave table, and
to attain that end I have devised an improved holder, which I am now about
to describe as auxiliary to the improvements herein-before set forth. It is
delineated in Figures 58, 59, 60, and 61, by reference to which I shall explain
its construction and application.
Figure 58 is an end view of the concave bed or table on which the pattern
plate is fixed from which the diamonds are worked. Figure 59 is a plan of
the middle portion of the same, shewing a pattern plate fixed thereon by my

page_text: improved strips or holders; Figure 60 is a profile or side view of one of the
improved holding strips, and Figure 61 is a plan of the same. E, E, E, are
parts of the standing frame of the machine, to which the iron bed F, with its
superincumbent wood bed G are attached; H is the pattern plate, and y, y,
the improved strips or holders, shewn detached at Figures 60 and 61. They
consist of long plates of tempered steel (or other suitable material) about one
inch in width, and of a thickness equal to about No. 10 wire guage. y' is a
metal nib attached to the end of each strip for the cramps z, z, to take hold
of; is an abutment of metal plate to retain the ends of the holding strips,
which are forced against it and lodge in a rebate formed in the under side.
The strips overlap the edges of the pattern plate, and are forcibly pressed
downwards thereupon by the action of the cramps 2, 2, with the finger screws
23, 2. The effect of the pressure of the cramps upon the holding strip, the
ends of which are confined by the abutment 2, is to force them downwards
upon the edges of the pattern plate H, which they confine to the bed or concave
table more closely and evenly than any of the methods heretofore in use for
that purpose.
Having now described the nature of my said Invention, and explained
the manner in which the same is to be carried into effect, and having been
under the necessity in so doing of referring to and describing along therewith
many old and well known parts and combinations of parts of the mechanism to
which my
Invention has reference, I shall conclude by briefly recapitulating and
distinguishing the particular modes of construction, arrangements, and com-
binations which I claim as new and of my Invention, and I therefore declare
