improvements in Machines for Cutting Patterns from Fabrics and
the like.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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 :-
This invention relates to novel mechanism and combination of mechanisms, by
which patterns are cut corresponding to forms or blanks which are secured to and
are reversible by means of a revolving table
The nature of the invention, novelty of the mechanism, and the method of
operation will be fully comprehended by the following detail description

Figures 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 15, 16, 18, 19, 20 aud 21 are drawn to
an enlarged scale..
A, A, represent, as shown, a substantial frame of iron, or other suitable material,
which supports the mechanism hereinafter described.
R, S, P, O, N, represent a reciprocating carriage which supports the operating
mechanism of the machine The bars R, S, are parallel and at one end of the
machine, they are connected by a bar P. At or near the bar connections are
pivoted vertical rollers ee which travel on one end of the frame piece A as a track.
The bai R, at its opposite ends is made rigid to a transverse bar O, which is nea
to the mid-length of the machine and has a support on a parallel bar 22, under-
neath, by means of rollers ff. The bar S, is rigid to the bar O, and its farther
end is supported to travel on the farther end frame piece of the machine by means
of a vertical roller 23. Projecting horizontally from the bar O, as a part thereof,
is an arm N. This construction is such that the carnage and arm may have a
reciprocating movement parallel with the end frames of the inachine. B, is a circular
table which is formed to be turned within a bed-plate B' which is held adjustably in
position by a set screw Y extending through the frame and engaging the table.
The purpose of founing the table to rotate is that the position of the profile
pattern on the wheel may be reversed relative to the patterns to be cut out of the
mateual A, as shown by dotted lines X and W, Figue 1, whereby the largest
number of patterns may be cut from the given material employed. A directing
wheel Figmes 1, 3, 4 and 5, turns on a post of which turns in the frame L'. This
frame is stationary and is affixed to the frame of the machine, and the pinion K¹
carrying the toothed wheel I' is affixed to the post o', and the post passes loosely
through the directing wheel 1', which lies within the surrounding frame L', and is
adjustable on the post therein The post o extends above the wheel I Figure 4,
and is gidly affixed to the radial arm C. The pinion K' meshes to a rack
lever C, and when the radial arin C is turned the pinton K' will be turned to move
the rack-lever C to the right or left, as the case may require to give the pantograph
position to the mechanism for the machine to cut different forms of patterns. The
ack lever is held in relation to the pinion K', by means of guide rabbets 24, 24,
Figure 5, which are within the said frame L' The rack-lever C, is rigid to an
elbow-level J, and also pivoted to a lever D, which by means of a slot E and a
pin, is adjustable on the arm N, which moves with the carriage R, S, P, O, and the
fever D carries a quadiant F, Figue 1, by which it is adjusted by means of a
suntable set screw G to give different angles to the rack lever C relative to lever D.
This construction is such that when the set screw G, is loosened, and the wheel is
turned, the levers C and D will have different relative angles to each other; and if the
pinion K' travels on the rack-lever C to the night, the angle between the levers C
and D will be more acute, and if tuned to the left the angle will be less acute
The means of adjusting the wheel 11 with reference to the radial aim C¹ consists of
the dog F, G', pivoted to said arm and provided at its lower end with a thin
engaging portion which engages the cogs in the wheel I' and the means for locking
the arm Cand consequently the wheel I' to the fiame L' consists of a set screw F',
Figures 3 and 4, tapped through the outer end of the aim to bear against the rim
of said frame. The pinion K being rigid to the whee! I' is governed in rotation
by the turn of the wheel I'; and the longitudinal movement of the rack-lever C is
governed by the same means. Sometimes, to save the necessity of cutting the fine
teeth on wheel 1', I employ a sub-wheel 1, and set the wheel I so that its teeth
will overlap the interspace between the teeth of the wheel 11. In such case I
employ an extra support and dog, as shown at Figures 3, 10, and 11. D', D' show
two adjustable stops on the rim of the frame L¹ to regulate the throw which the
radial portion C' may require. A cap T, a rigid portion of frame I' extends over
a portion of the wheel 1', and to it are affixed rollers M' which bear against the

page_text: h
outer edge of the rack-lever C and hold the teeth in nesh with the pinion K¹. A
reciprocating carriage h, Figure 1, is provided with rollers g, and fitted readily to
travel on the portion S of the main carriage, and its outer end is connected with the
frame L' of the wheel 1. Distant from the carriage is a carriage, which is
provided with rollers n, to engage and travel also on the main curinge portion S.
A rod connects by pivots with the carnage, and the opposite end is pivoted to
the cap T of frame L, by which the movement of the wheel 1' is communicated
to wheel H, whereby any change in position, given to the carriage by the point N'
encompassing the pattern r, on the table B, will be communicated longitudinally to
the cairinge, having a lateral support in arm Z which is igid thereto, and is
supported by a roller to travel on the bar R of the main caritage A dnecting
wheel H, in all respects a duplicate of wheel I and carrying a like pinion and
operating in a like frame and having an over-lapping portion U, sun:lar to T, has
its frame portion attached to the caringe 1, and the mechanism shown at M, K, I, L
and G, is identical with the mechanism shown at C, J, F, D, and G, heretofore
described. The lever M, serves the saine pui pose in its place as the rack-lever C
does in its place, Figure 1, and it is operated by a like pinion as the pinion K', and
it supports igidly an arm K, with the set screw G. It is also pivoted to the
lever L, which supports a quadiant I by which, and the lever K, the levers Mand L
are to be set at the same angles as the levers C, D. The lever L is jointed to the
frame portion Q.
k, Figures 1, 2, 20, and 21, represents the yoke head of the machine which by
means of rolleis II' and ' and '18 arranged to have a reciprocating movement on
a track, and by roller 20 to travel on bai I, the brushes J being employed to
keep the bar free from chips. The bars or tracks, are secured to the main
carriage of the machine. A connecting bar V is at one end pivoted to the cap
plete U of the trame of the duecting wheel H, and at the opposite end is pivoted
to the joke head k, whereby any change in the angles formed by the levers L, M,
by the tuin of the wheel II, will move the head longitudinally on the bar or
trick J.
This gives lateral expansion to the cutting punch an area equal to any lateral
motion the transcribing point N° may have, anil a greater lateral notion than the
bars R, S independently have. A separate fraine is formed by the sleeve, bar Z
and a connecting rod g with the slide or sleeve h. Within the bar Z and directly
over the bar R, is placed a roller 1, to guide, with the aid of the sleeve i, the
track and head K at right angles to and forward and back between the bars R, S.
When the bar or track 7 is adjusted to have the same movement relative to the
pin N, as to the punch the parts are fixed relatively by the rod K, to the
post Land the lever 1 fixed to the bar Q, then the curved bar r, being pivoted to
the head K at one end, and to the cap-plate U at the other end, gives to the
pantograph movement longitudinally with the bars R, S, greater motion than the
Interal movement of the bar on head k by reason of the angular motion of
the levers C, D and L, M.
h
From this descuption it will be seen that I provide three distinct movements,
one of the mau cairage transversely with the machine, a movement by means of
the carnage, and the post A longitudinally with the machine, and a reciprocating
movement of the yoke head independent of the movement of the main carriage;
by this means sufficient expansion in the mechanism is attained to cut a pattorn
from the material A³ in any forms or curves of the pattern r.
In the enlarged view, Figure 20, ' represents the convex die which is provided
with a vertical hole corresponding to the diameter of the round punch, such
form of die giving a better cutting edge than one flat on its top portion. The die
post C, has a vertical bearing in the yoke head and an angular connecting
od A, B, engages the post and is pivoted to an eccentric E, which is concen-
trically connected with a shaft p, and is driven by it to give to the punch 'a
vertical reciprocating motion.
Frepresents an adjustable shaft bearing adjoining the eccentric, and is

page_text: vertically adjustable by means of a pin A secured thereto and projecting through
a slotted segment n', G³, n' being the segment, and G the slot which guides said
pin. An elbow lever m' 19 pivoted to a fixed lug 12 and its lower end engages the
pin A; so that when the lever is brought down the bearing F, s
, shaft P, and post C
and punch will be elevated above the material which bears on the die h'; whereby
the punch is kept in motion, but it does not cut while the machine is being adjusted
to cut on a different portion of the material A°.
B' represents the bearing to the opposite end of the shaft, and e²e are the bevel
gears which connect the shaft with the gear ', which, with the wheel a is changeable
in position relative to the wheel c. A frame swings on a post D* Figure 2, and
the post is driven by any suitable power applied to wheel 21; by this means the
wheels a, b, c and the gear e are driven with such speed that the punch f' cuts
the edges of a pattern W, Figure 1, so evenly that it can be bound with metal
without trimming
Figure 20, represents a suitable foot attached to a deponding standard on
upper portion of the yoke head k, to keep the material to be cut from rising from
the die. This construction differs from the somewhat like part in the sewing
machine, in that a flat or concave ended punch is preferably employed, and the
mechanism is such that the punch constantly has its reciprocating motion the same
when inised above the material to be cut as when operating in the die; and the
yoke head has a reciprocating movement on a track or bar, while the head or
arm of a sewing machine is a fixture on the table, again, the purpose is not
analogous.
The reciprocating table for ffolding and adjusting the material to be cut is shown
at G, and in it are formed a series of dove-tail giooves, 18 Figure 14, suitable in
number to support the necessary two-pronged sliding clamps m, 10, to grasp and
present the material to be cut between the die A' and the foot g', four such clamps
being shown at Figure 14, and five at Figure 1. The detail of these clamps 18 more
clearly shown at Figures 15, 16, 17, 18 and 19.
The lower prongs 10 run in the grooves 18, shown also in a portion of the side
elevation of the bar 4, at Figure 17. This cross bai 4, is secured to the table G',
and though it are tapped set screws 8, by which any one clamp may be adjusted
longitudinally in its groove in the table. Preferably the upper prongs m, are
provided with teeth 17, Figures 16, 18 and 19, hrmly to hold the material in place
Better to accomplish this purpose a bar 14, 18 made to extend transversely across
the table and is rigid thereto, and to the bar are pivoted cam levers 13, one for
each clamp, whereby the upper prongs m can be made to clamp with suitable force
the material between the two prongs. The table G, is fitted to run in ways 15, 15,
secured to the frame of the machine, Figure 14, and to the table is attached a
ack 7, and the ways serve as bearings for a shaft 12, on which is mounted a
pinion 6 engaging said rack, whereby when a'wheel A¹, mounted on the shaft 18
turned the table will be moved in or out of the ways as may be required to bring
the material from which the patterns are to cut to the punch.
K³, represents a rod which is rigid to the carnage h, by means of an arm. and
extends through a guide block Land a set screw is tapped into the block to
leck the carriage h, to the portion O, of the main carriage, when an adjustment is
being made in Figmes 12 and 13. Y is the set screw by which the revolvable
table B 18 adjusted to a desired position on the frame B. 2, 2, 2, 2 are the
recesses by which the profile pattern is to be held to the table B, and 16 is the nut
and bolt hy which the table B is held to turn on the frame B'.
In Figure 1, is the profile pattern around which the point No of the pantograph
mechanism traverses
A is the material from which the pattern W, dotted lines, is to be cut, and the
same being a duplicate of the profile pattern 7, secured to the table B
When one
pattern is cut the table B is to be turned half round and then another pattern is to
be cut. Suppose a different profile pattern be employed, the levers D, C and L, M,
are to be adjusted so that the traversing point No put through the frame will

page_text: traverse the edge of the new pattern. When the said parts are adjusted, the set
Screws heretofore mentioned hold the paitsiigid. The traversing point N° is moved
round the profile pattern by the hand engaging the carriage h.
Hasing now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I wish it understood that
I do not broadly claim a pantograph on the cutting of patterns from a profile
