Improvements in Profiling Machines.
I, DAVID YOUNG, Patent Agent, of the Firm of D. Young & Co., of 11 and 12
Southampton Buildings, London, W.C., 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:
My invention relates to profiling machines.
My object is to produce a machine by which a duplicate of a pattern is repro-
duced by a suitable cutting tool, which is guided by the pattern through
intermediate mechanisms, and is so reproduced of equal or larger or smaller size
than the pattern, according to the adjustment of the tool guiding mechanism.
It is herein described and shown for the purpose of reproducing numerals, letters
or characters, by cutting them in relief upon the face of a plate, or upon the flat
end of a bit or ward or lug upon one side of a key, but it is evident that it can be
applied to many other purposes without departing from the principle of my
invention, and can reproduce an intaglio from such a pattern, the same as a
design in relief from that type of pattern.
This machine embodies a tracer, a pattern table, and a work table and' means
whereby it is elevated or lowered toward or from a revolving cutter, and the tracer
vertically toward or from a pattern table, which tracer is caused to follow the
contour of the pattern and direct and control the forward and back diagonal
or lateral movement of the cutter, according to the contour of the pattern,
and to produce it, means being provided for regulating and adjusting
the lift or elevation of the work table, and tracer whereby the depth
of the cut made by the cutter is controlled; means also being provided for
lowering said work table for the removal or insertion of finished work; and in
which each cutter is carried by a holder consisting of slides in a suitable series of
ways and so connected to said tracer that every possible movement of the said
tracer is imparted to the cutter.
My invention consists in the several novel features and combination of elements
hereinafter described and which are specifically set forth in the claims hereunto
annexed.
It is constructed as follows, reference being had to the accompanying drawings
in which-
Fig. 1, is a front elevation of the machine.
Fig. 2, is a vertical sectional elevation thereof, showing the table depressed.
Fig. 3, is a top plan of a pattern, and also of its reproduction upon a lug on one
side of the shank of a key.
Fig. 4, is a top plan view of one end of the connecting link and its mounting.
Upon a suitable base a standard 3 is erected; provided with an arm 4 having
its ways 5 upon which a slide 6 is mounted having a suitable gib 7 and set screw 8
to regulate the fit of said slide upon these ways.

page_text: This slide is also provided with suitable ways, 9 upon which a counter-slide 10
is mounted, with a gib and screw 11.
An angular arm 12 is secured, to said counter-slide and 13 is a tubular nut
adjustably inserted into said arm, and through which a cutter shaft a is inserted
having a bearing shoulder 14 said nut being also recessed to receive a lesser
tubular nut which adjustably bears upon said shoulder to prevent the upward
thrust of said shaft, the upper end of which has a bearing in a step 15 in the
counter slide, and 16 is a suitable pulley on said shaft, driven by a belt 17 from
any suitable source of power.
A suitable chuck 18 mounted upon said shaft holds a suitable cutter, or cutting
tool 19.
Upon suitable vertical ways upon the front of the standard, work-tables are
separately mounted to be reciprocated vertically, and 21 is a suitable supporting
and lifting spring, normally holding said table up so that the upper end of the
stud 22 will engage with a set screw 23 which is adjustable to vary the lift of the
table, and the depth of the cut made by the cutter.
The tables 20 are adjustably mounted upon the slides 20¹, so that each table
may be adjusted to the length of the tool which operates upon it. This adjust-
ment is made by a set screw 21' mounted in a plate, secured to the lower end' of
the main 'slide 2011.
The slides 20¹ upon which the tables are mounted comprises the main
slide 20", which is operated as hereinafter set forth.
Upon these tables suitable work holders c, are mounted, those shown being
recessed to receive and hold the shauk of a key 24 provided with lateral lugs 25
upon the upper face of which (as shown) the pattern is to be reproduced by said
cutter, the hand-screw 26 suitably engaging with said key to hold it securely.
29 is a pattern table suitably mounted upon the base and upon which the
pattern 30 is secured, such as is shown in Fig. 3, except that for some purposes
the pattern should be reversed as when the reproduction is to be used for printing.
To depress the work table the rack 36 mounted upon the main slide 2011 engages
with a pinion 37 upon a shaft 38 which in turn is operated by the lever 39.
Upon the shaft 38 is a drum 40, to which a cable 41 is secured; the cable 4'1
passes over the pulleys 42 mounted upon the top of the frame and is connected to
the vertically yielding tracing finger 43:
Upon the front side of the counter slide 10, which has a lateral movement, a
connecting link dis swingingly mounted, by means of the set screws and d¹,
the end of said link being connected by an universal connection to the pattern
guide.
This pattern guide comprises a body 46, having a flat enlarged upper portion 47,
the interior being removed or cut away forming an opening 48, and 49 is a
centrally perforated block mounted upon set screws 50. in the opening 48 and 51
is a similar block mounted within the block 49 and similarly held; within said
block 51 is the link d swingingly mounted.
The opening 52 in the block 51 of the pattern guide has both of its ends beveled,
and the shoulder upon the link d correspondingly beveled to fit the same.
Upon the outer end of said block 51 is a beveled nut 511 held in place by a
jam nut 521, the object being to permit of taking up any possible wear or play
that may be occasioned.
The upper end of the pattern guide is pivoted to the swinging plate 54 by means
of set screws 55.
It will be observed that by moving the pattern guide in or out, the slide 6 will
he simultaneously and correspondingly moved on the way 5.
The plate 54 is mounted upon a bolt 56, and adapted to rock, and it will thus
be observed that by rocking the pattern guide 46 side ways, it will cause the
counter slide 10 to inove in a corresponding direction on the way 9.
It will thus be observed that whatever movement is given to the pattern guide
a corresponding and simultaneous movement will be imparted to the slide 6, and
5
6

page_text: the counter slide 10, which in turn, by the intermediate connection, will impart
a similar movement to the cutting tool 19 within the chuck 18.
In Fig. 3, I show a pattern and its reproduction upon a reduced scale, but
where the reproduction is to be used in printing, the pattern should be reversed.
In case the pattern, in any part has a recess within the border, as the
numerals 6, 9 or 0, the finger 43 being yieldingly mounted in the pattern guide, is
raised by means of the cable 41' mounted upon the drum 40, by operating the
lever 39.
It will thus be seen that by the operation of the lever 39; the work table,
holding the key will be brought in contact with the tool, and at the same time,
the yielding finger 43 will be lowered next to the pattern to allow the operator to
trace the same.
The relative scale or proportion of the reproduction to the pattern depends upon
the set of the machine."
This machine is shown in the drawings as performing its work in triplicate,
making three reproductions simultaneously from a single pattern with a single
tracer, and by duplicating substantially the construction shown, its capacity can
be increased to any desired number.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, as communicated to
me by my foreign correspondents, I declare that what I claim is:
-
1. In a profiling machine, an adjustable work table, and a stationary pattern
table, in combination with a tracer and a revolving cutter, so connected thereto
ns to be guided by the contour of the pattern upon the pattern table.
2. In a profiling machine, an adjustable work table yieldingly mounted, and
a stationary pattern table in combination with a tracer, and a revolving cutter,
so connected together that a lateral movement of one will be simultaneously
transmitted to the other, as set forth.
3. In a profiling machine, a work table vertically adjustable, and a stationary
pattern table, in combination with a tracer having a tracing finger and a
revolving cutter so connected thereto as to be guided by the contour of the pattern
upon the pattern table, the work table and tracer finger being so connected that
the raising or lowering of said work table will operate to simultaneously operate
the tracing finger.
4. The improved machine constructed substantially as described with referenco
to the accompanying drawings and operating as and for the purposes above
specified.
