"IMPROVEMENTS IN APPARATUS FOR HATCHING, RULING, AND DRAWING ON
STONE AND OTHER MATERIALS." (A. communication from abroad by Messieurs
F. Martini & Co., of Frauenfeld, Switzerland.)
This Invention has for object improvements in apparatus for hatching, ruling,
or drawing straight, curved, or undulatory lines on stone, steel, copper, wood, or
other material, and has reference, firstly, to means for effecting the feed or
intermittent sideways motion of the marking instrument in such apparatus;
secondly, to means whereby the amount of the feed may be automatically increased
or diminished gradually so that lines may be drawn at gradually increasing or
diminishing distances apart; thirdly, to means for effecting the ruling or drawing
of undulating lines; fourthly, to the construction and operation of the slide and
holder that carries the marking instrument.
A sliding arm is carried at one end on a fixed rod, and is furnished with clamping
pieces which embrace the said rod and are free to slide endways in a recess in the
arm, being biassed in one direction by a spring. With these clamping pieces is
combined a spindle formed or provided with an eccentric, whereby the clamping
pieces may by turning the spindle be caused to clip the rod when required. The
eccentric spindle carries a finger which abuts against the sliding arm and a hand
lever which can be turned through a distance determined by an adjustable stop.
The effect of turning the hand lever and eccentric spindle is to lock the clamping
pieces against the rod so that they form an abutment or fulcrum that enables the
finger on the spindle (as the lever is moved further) to push the sliding arm (which
Dion C

page_text: carries the marking instrument holder) forward through a distance depending on
the range of motion of the hand lever. The adjustable stop is made in the form of
an eccentric or cam and is attached to an index lever pivoted on a stud. This
lever can be secured opposite any point on a scale, or it can be left free and be
controlled by contact of its unmarked end with an inclined adjustable lever by
which, as the index lever is carried forward by the intermittent motion of the
sliding arm, it is gradually pushed over to automatically alter the distance apart of
the lines to be produced. The angular motion of the index lever varies the position
of the eccentric stop with relation to the hand lever hereinabove described, and,
consequently, varies the amount of feed imparted to the sliding arm by the motion
of the said hand lever.
Upon or in the sliding arm are undulating lines or grooves, into either of which
a screw or screws on the marking instrument holder can be entered, so that the
said holder in travelling along the said arm may be obliged to follow an undulating
course.
The holder that carries the pen, pencil, diamond, or other marking instrument is
pivotted to a bracket which is hinged to a slide working along the sliding arm.
The lever or handle by which the said slide is moved backwards and forwards to
draw the lines also serves to raise the marking instrument from the material to be
drawn or engraved upon at the end of each course.

"IMPROVEMENTS IN APPARATUS FOR HATCHING, RULING, AND DRAWING ON.
STONE AND OTHER MATERIALS." (A communication from abroad by Messieurs
F. Martini and Co., of Frauenfeld, Switzerland.)
This Invention has for object improvements in apparatus for hatching, ruling, or
drawing straight, curved, or undulatory lines on stone, steel, copper, wood, or other
material, and has reference, firstly, to means for effecting the feed or intermittent
sideways motion of the marking instrument in such apparatus; secondly, to means
whereby the amount of the feed may be automatically increased or diminished
gradually, so that lines may be drawn at gradually increasing or diminishing
distances apart; thirdly, to means for effecting the ruling or drawing of undulatory
lines; fourthly, to the construction and operation of the slide and holder that
carries the marking instrument. A sliding arm is carried at one end on a fixed
rod, and is furnished with clamping pieces which embrace the said rod and are free
to slide endways in a recess in the arm, being biassed in one direction by a spring.
With these clamping pieces is combined a spindle formed' or provided with an.
eccentric, whereby the clamping pieces may by turning the spindle be caused to
clip the rod when required. The eccentric spindle carries a finger which abuts
against the sliding arm, and a hand lever which can be turned through a distance
determined by an adjustable stop. The effect of turning the hand lever and
eccentric spindle is to lock the clamping pieces against the rod, so that they form
an abutment or fulcrum that enables the finger on the spindle (as the lever is
moved further) to push the sliding arm (which carries the marking instrument
holder), forward through a distance depending on the range of motion of the hand
lever. Thus it will be understood that the hand lever spindle and finger form
together the mechanism for effecting the feed or intermittent sideways motion of
the marking instrument.
It will also be evident that the details of construction of this mechanism are
susceptible of modification, without departure from the essential characteristics of
the Invention. The adjustable stop is made in the form of an excentric or cami,
and is attached to an index lever pivotted on a stud. This lever can be secured
opposite any point on a scale; or it can be left free and be controlled by contact of
its unmarked end with an inclined adjustable bar, by which as the index lever is
carried forward by the intermittent motion of the sliding arm, it is gradually
pushed over to automatically alter the distance apart of the lines to be produced.
The angular motion of the index' lever varies the position of the eccentric stop
with relation to the hand lever hercinabove described, and consequently varies
the amount of feed imparted to the sliding arm by the motion of the said hand
lever.
Upon or in the sliding arm are undulating lines or grooves of varying depth, into
either of which a screw or screws on the marking instrument holder can be entered,
so that the said holder in travelling along the said arm may receive an undulating
or rocking motion. The holder that carries the pen, pencil, diamond, or other
marking instrument, is pivotted to a bracket which is hinged to a slide working
along the sliding arm. The lever or handle by which the said slide is moved
backwards and forwards to draw the lines, also serves to raise the marking
instrument from the material to be drawn or engraved upon at the end of cach
course.

Fig. 14 shews two elevations of the handle for moving the slide and marking
instrument backwards and forwards.
1 is a frame which serves as a base for the other parts of the apparatus. It is
faced or covered on its lower sides with caoutchouc cloth to form a yielding
cushion between it.and the surface of the material on which it may be laid; 2 is a.
sliding arm forming a guide for the slide 16 which carries the marking instrument.
The fixed rod 5 is supported in bearings at each end in the slide 2, and acts as
an additional guide to the slide 16. The rod 4 is secured in bearings upon the
frame 1, and is designed inter alia to form a guide and support for one end of the
sliding arm 2, which slides at its other end on the plane surface m. The mechanism
which effects the feed, and which is shewn in greater detail in Figs. 6, 7, 8, 9, 10, 11,
and 12, is situated at the left hand end of the sliding arm 2. 3 is a packing or
filling piece secured to the sliding arm 2 by two screws 13, 13, (Figs. 1, 6, and 8);
6 is a clamping piece embracing the rod 4 (Figs. 8, 9, and 10), and fitting loosely
with provision for endwise motion in a recess in the sliding arm 2; 7 is a second
clamping piece or key, fitting in a groove in the first clamping piece, and secured
from moving endwise in the said clamping piece, by the point of the set screw 8
which takes into a hole bored for its reception in the piece 7; 11 is a helical spring
fitting in a recess in the clamping piece 6, and abutting against the sliding arm 2;.
9 (Figs. 6, 8, 10, and 12) is a spindle carried by the clamping piece 6, and provided
with an excentric or cam like portion in its lower part, and a square surmounted
by a screw at its upper part. Below the squared part is fixed a finger a (Fig. 6)
lying in a recess or slot in the cover plate (Fig. 10), and on the squared part is
secured a hand lever 10 (Figs. 1, 2, and 3). This hand lever can be turned from the
position in which it is shewn towards the left hand until it comes in contact with
the cam or excentric stop fattached to the lever 21, which is provided with the
index finger and the screw 15, by which it can be secured in any position with
regard to the scale numbered 0 to 5. The bar 22 is pivotted at one end, and
secured at the other end by the set screw 23. Its angular position with regard to
the rod 4, and consequently with regard to the path of the sliding arm, may be
varied, a slot being provided through which the set screw passes for the purpose.
The marking instrument is fitted in a socket or holder 18 which is pivotted to a
bracket or carried between centres on the slides 16. Either of the screws / can be
set down until its point engages with one of the three different undulatory grooves k,
and thereby form a guide to oblige the slide to carry the marking instrument along
an undulatory path. It is to be noted that the grooves as seen from above are
parallel, but being of varying depth have the effect of raising the screw, therein

page_text: allowing it to descend, thus imparting to the drawing or marking instrument such
a movement that the lines thereby produced will be undulating. The slide 16 is
moved backwards and forwards by the handle 20 (Figs. 4, 5, and 14), which is
pivotted to the stud b. The hole c receives the stud b.
The toe d of the lever 20 stands under a part of the arm e (which is provided
with the weight h) and serves to raise (through the interposition of the arm e) the
marking instrument from the material to be engraved at the end of a line. The
marking instrument must be raised previous to and during its.return motion, and
be lowered with its point on the exact position for commencing the next line.
K, K, are handles.
The operation of the apparatus is as follows:-It is laid upon the surface or
material to be drawn or engraved upon; the stud b of the handle 20 is placed in
the hole c, and the marking instrument carried in the holder 18 adjusted to the
position for the first line commencing at the left hand side. The slide is drawn
from left to right by the handle 20 held in the position shewn in Fig. 4, and on
the completion of the line is pushed back by the handle after the said handle has
been lowered into the position shewn in Fig. 5 to the starting point. Simul-
taneously with the return of the slide the hand lever 10 is pushed over by the left
hand of the operator until it comes against the stop f, thereby actuating the feed
mechanism, and carrying the sliding arm sideways through a space equal to tho
pitch or distance from centre to centre of adjoining lines. The angular motion of
the hand lever rotates the spindle to which it is attached, and brings its eccentric
or cam like portion to bear against the clamping piece 7, thereby causing the two
pieces 6 and 7 to tightly embrace the rod 4, so that they form an abutment or
fulcrum that enables the finger a on the spindle (as the lever is moved further) to
push against the cover plate 12 and to move. the sliding arm forward through a
distance dependent on the range of motion of the hand.lever. On the return of
the arm to its original position the spring 11 pushes the clamping pieces again to
the end of the recess. When ruling lines at gradually increasing distances the.
range of motion of the hand lever is automatically increased at each operation of
the feed mechanism by the index lever 21 receiving an angular movement, resulting
from its being carried forward while its end is in contact with the inclined bar 22.
The movement of the index lever partially rotates the cam or excentric f and
varies the limit of the travel of the hand lever.
The apparatus may be constructed to trace convergent lines by joining the
sliding arm 2 to the feed mechanism by a pivot or hinge joint and by providing a
suitable support for its other end.
Having now described the nature of the said Invention and the manner in
which it is to be or may be carried into practical effect as communicated to me as
aforesaid, I would have it understood that what is claimed as new and secured to
me under the Letters Patent hereinabove first in part recited is,-
1. In an apparatus for hatching, ruling, and drawing on stone or other materials,
the combination with the mechanism for effecting the feed or intermittent sideways
motion of the marking instrument of a clamping contrivance whereby the said
mechanism is carried, and which clamping contrivance can, by being put in
frictional connection with a stationary part of the apparatus, be fixed so as to form
an abutment or fulcrum for the said mechanism, and can be released from such
frictional connexion at will, substantially as described.
2. In a machine for hatching, ruling, and drawing on stone or other materials,
the combination with a sliding arm (serving as a guide for the marking instru
ment) and a rod or device along which that arm is adjustable, of clamping pieces,
a spindle with an excentric or cam, and a finger or projection, and a spring, the
whole so arranged that by a partial rotation of the said spindle the clamping
pieces may by the cam or excentric be caused to grip the rod or lever carrying the
arm, then the arm will by the finger or projection be moved a definite distance
along the said bar or device, and on the reverse movement of the spindle the
clamping pieces will be released by the cam or excentric, and be moved by the

page_text: spring into a position corresponding with that of the bar, all substantially as
described and for the purposes specified.
3. In apparatus for hatching, ruling, and drawing on stone or other materials,
the combination with the feed mechanism of an excentric or curved stop, a lever,
and an inclined adjustable bar, the whole so arranged that the amount of feed or
intermittent sideways motion of the marking instrument can be determined by
means of the said excentric or curved stop controlled by the said lever and inclined
adjustable bar, substantially as described.
4. In apparatus for hatching, ruling, and drawing on stone or other materials,
the combination with the slide that carries the marking instrument, of a guide
constructed with vertically undulating parts or grooves of varying depth, so
arranged as to cause the marking instrument to travel in a curved or sinuous
course, substantially as described.
5. In apparatus for hatching, ruling, and drawing on stone and other materials,
a slide constructed, arranged, and operating, as herein before described, to carry
the marking instrument.
6. The combination of parts constituting the improved apparatus for hatching,
ruling, and drawing on stone or other materials, constructed, arranged, and operating
substantially as described and shewn.
In witness whereof, I, the said William Lloyd Wise, have hereunto set my
hand and seal, this Nineteenth day of July, in the year of our Lord
One thousand eight hundred and eighty one.
