Improvements in the Method of Attaching the Fillets to the Flats
of Revolving Cards, and in Apparatus therefor.
I, KARL GOLDSCHMIDT, of Franz Josef Strasse, Brünn, in the Empire of
Austria, Card Manufacturer, do hereby declare the nature of this invention to be
as follows:-
The subject of the present invention relates to a system of mounting the fillets or
clothing upon the flats of revolving cards and the accessories and appliances used
for that purpose.
The flat is put upon a trough-shaped bedplate and held fast by means of the
adjustable blocks which are at the ends of the machine in the following manner.
In one block a screw is fixed and by means of a handwheel at the end of the screw
this block is pushed forward whereby the flat is held fast between the two blocks,
as the second block is screwed fast to the frame. Over the flat thus fixed or held
the fillet is laid. The latter is sometimes 1 to 3 / narrower and
to 25 D
shorter than the flat in order to admit of its being stretched.
By means of the following arrangement the fillet is stretched in the direction of
its length. On the blocks" which hold the ends of the flats there are catches of
which one can be turned round or swivelled upon a pin and on the left has an
oblique surface while on the right it is fitted with a hook. Against the oblique
surface a pressing lever is inclined which by means of the pin is fixed in a guide
frame firmly fitted onto the stand. The lever presses the left end of the catch
upwards and the hook consequently down against the fillet which is thereby held
fast. The second catch enables the fillet to be pressed against the flat and to be
stretched at the same time in a longitudinal direction. This catch is pivoted on
the pin and is provided with a hook which engages with a cord. On this pivot a
pulley is also fixed. The frame has a projection with grooves serving as a guide
for a double pivoted lever and is kept in position by a spring. On the upper half
of the lever there is a hook which is connected by a rope running over the pulley
with the hook of the catch. On the lever there is also a pawl. In order to insert
the fillet the double lever is turned to the left by hand. By this means a spring is
stretched and at the same time the pawl falls into a notch in consequence of which
the position of the lever is fixed. The fillet is now pushed under the hook and the
pawl lifted so that the spring comes into play turns the lever back the rope is
stretched and the book pressed against the fillet drawing it at the same time in a
longitudinal direction consequently stretching it longitudinally. Then follows the
stretching of the fillet laterally. For this purpose first of all the right longitudinal
side of the fillet is punched by means of a tool of the usual kind in such a way that
the holes correspond with those of the flat underneath, and then one of the steel
strips is laid on when the tongues of the steel bands penetrate the fillet and the
flat. The points of the tongues project underneath and the surface of the strip
extends a little over the fillet (in the direction of the width). In order that the
steel strip may hold the fillet fast the tongues are a little broader above than the
diameter of the holes in the flat. After the fillet has been fixed on one side in this
way it is stretched by means of the following contrivance in the direction of the
width. Above the bed upon which the flat rests an adjustable pressing and
stretching appliance is fitted. This consists of a gun metal bar on which by means
of screws a steel plate provided with teeth is fastened. At each end of the
metal bar there is a swivel pin fastened into the frame by means of which the
pressing and stretching contrivance can be raised and thus the flat and fillet can
gun

page_text: mi
im
be placed into position on the bed plate. The bar has at each end an arm provided
with notches and is actuated by pivoted levers. These levers are provided with a
three cornered piece which fits into the notches in the arm at the end of the bar.
A double lever carrying a movable weight is pivoted at the end of the frame and
when the stretching appliance is raised its arm rests against the firm frame. While
the flat is being laid on the bed plate and the fillet-laid thereon is being stretched
and fastened on the right side with the steel strip the pressing and stretching
contrivance is raised and rests upon a fixed artn in the end of the frame. After the
flat has been laid in position and the fillet prepared in the manner described it is
requisite to stretch the latter in the direction of the width because as already
remarked it is 1 to 3 mm narrower than the flat. In order to accomplish this the
pressing and stretching appliance is lowered which causes a steel plate affixed to
the longitudinal bar to be laid on the left uncovered edge of the fillet when the
teeth prevent any movement of the fillet. The gun metal bar lies in a slide on
guides on the frame which can be pushed to and fro by the screw spindle fixed in a
female screw by turning a hand wheel. By the turning of the handwheel the gun
metal piece and the steel plate attached to it pressing on to the fillet are drawn to
the left in consequence of which the latter is stretched laterally. The fillet is
then perforated on the left side the holes corresponding with those in the flat
underneath and as before fastened with steel strip. Owing to the tongues being
broader above than the diameter of the holes in the flat the fillet is sufficiently
fastened to the flat.
The tongues of the steel strip which pass through the fillet and the flat and
project from the latter have now to be bent hack and the edges of the steel strips
which extend right and left (longitudinally) over the edge of the fillet must be bent
to a right angle. Through the deflection of the points of the tongues projecting
from the flat the fillet is made still firmer, whilst by bending the faces of the steel
strips to a right angle this important advantage is obtained, the fillet is encircled
laterally by the steel strip which lies in one level with the side face of the stretched
flat.
For the performance of this work a head containing blocks is employed. The
under part of this head is formed as a matrix for a screw spindle which is driven
by power transmitted through conical change wheels in the usual manner. When
the work is begun the head is on the right side of the machine. This head consists
of the under part on which the supports are fixed and slide along a dovetailed
groove. By means of a screw which fits into a fixed matrix the supports can be
pushed to and fro by a hand wheel. Into the head slide arms are pushed which
carry small screw studs on which rollers are placed. Through the action of a
spiral spring these arms are constantly pressed inwards. The consequence of this
is that the rollers deflect the points of the tongues below when the head is turned to
the left by the revolution of the screw spindle. On the supports additional
supports which can be pushed up and down are fixed and to these the clamping
blocks are screwed. The latter are inclined or curved towards the end in order to
deflect to a right angle the projecting edges of the steel strips when the spindle is
turned and the head is consequently moved to the left.
In order to produce the steel strips which are used for the fitting of the flat and
the perforations of which correspond with those in the flat the appliance of special
construction is made use of. It is attached to the stand of the machine already
described and by means of belting or any other appliance that may be chosen it is
driven. The most importaut part of this appliance is the piece which catches into a
hollow slide or carriage on to whose end or tongue a catch terminating in a point is
fitted and by means of a spring is constantly pressed onto the flat and when the
slide moves forward by catching into the holes of the flat it moves the latter
forward. The piece can be turned round a pin both to the right and left. With
its upper end onto which a screw is fitted it catches into an eccentric. By the
revolution of its shaft the eccentric causes the piece and with it the slide to move to
and fro in consequence of which at every movement to the left of the catch the flat

page_text: is carried forward a hole. In order to carry the lower end of the piece to the right
again and with it the catch the slide or carriage bearing the piece is taken on to a
firm pin and after the flat has been moved forward a hole it is drawn again to the
right by a spiral spring as the present position of the eccentric admits of a
movement to the left of the upper half of the piece. The catch again catches into
a hole of the flat and then the jerky forward movement of the latter is repeated.
The flat for which the corresponding strips are being perforated is by means of
screws fixed between two or more sides. The latter slide on a square metal piece
which possesses a nut which catches into a screw and thus a safe guide is secured.
The square piece is screwed on to a block which is fastened to the framework of
the machine. On the left extension of the square piece rests a guide for the steel
strip whereby the flat is firmly connected with the strip and the latter is compelled
to make the same jerky motion as the flat.
On the eccentric shaft near the eccentric there is a second eccentric fixed. By
turning the same the sliding strip is pushed to and fro. This strip is connected by
a spring with the press lever and the sliding piece possesses slots through which
screws which are screwed into the bedplate project. Over the press lever a plate
is fixed which by means of screws is firmly fixed in the ground or bed plate. When
the eccentric is turned the steel band and with it the press lever is first moved
forward in consequence of which the pressing surface of the lever recoils from the
pressing surface of the fixed plate so that when the eccentric is turned further the
steel strip guided between the pressing surfaces mentioned which may be clipped
and this happens when the upper end of the piece reaches its furthest position on
the left and the catch has pushed the flat a hole further. At the same moment the
perforating arrangement subsequently described comes into operation and punches
a tongue which is effected in the following manner. On the shaft is fixed an
eccentric with which the lever which is firmly screwed onto the shaft is in contact.
The axle is fitted into the bearings and carries the stamp block with the stamp.
Now when the eccentric reaches the highest position and consequently the upper
end of the lever presses upwards the stamp penetrates the firmly held steel strip
and perforates the tongue as through the upward movement of the upper half of the
lever the stamp block moves downwards and the stamp penetrates the steel strip
from right to left.
The stamp is fitted with an oblique edge by which the perforated tongue is
simultaneously bent outwards and with the steel strip forms an angle of 40 to
60 degrees. Now comes into operation the press lever the motions of which are
regulated by another eccentric its spike penetrates above the perforated opening
near the tongue in consequence of which the latter is brought into a vertical
position on the steel strip as the tongue slides up on the oblique surface of the
spike. The press lever is pushed back again by a spiral spring.

5 Improvements in the Method of Attaching the Fillets to the Flats
of Revolving Cards, and in Apparatus therefor.
I, KARL GOLDSCHMIDT of Franz Josef Strasse, Brünn, in the Empire of
Austria, Card Manufacturer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and
O ascertained in and by the following statement :—
3
The object of my invention is to provide an improved system of mounting the
fillets on the flats of revolving cards.
By means of an apparatus which I will hereafter describe, I obtain a perfect

page_text: tongues.
Fig. 14, is a section on line G H of Fig. 11.
Fig. 15, shows a cross section of a flat when stretched.
Fig. 15, shows the flat when the steel strips or holders have been placed in
position and the side edges of which are shown projecting somewhat over the side
edges of the fillet.
Fig. 16, is a plan view of a flat.
Fig. 17, is a plan view of the punching device.
Fig. 18, a part sectional elevation of same, and
Figs. 19 to 254, are details of said punching device.
Fig. 26, is a front elevation of the punching device, and
Fig. 27, plan of parts of Fig. 26.
Figs. 27, 27, and 27° are details.
The flat (a) is first of all placed in position in a trough-shaped bed-plate (b)
between a travelling or adjustable, and a stationary block 61 mounted at the
left and right ends of the frame of the machine respectively the adjustable
block being worked to and fro by means of a hand wheel c at the end of a
screw fixed in said block, whilst the stationary block is firmly fastened to the
frame.
The block is then worked forward so as to engage with and pin the flat (a)
vice-like between it and the stationary block. The flat being now immovable, the
fillet (d) is laid on to same.
The fillets are very often made from one to three millimetres narrower and five
to twenty-five millimetres shorter than the flat, in order to allow for stretching.
When this is the case, I stretch the fillets in both longitudinal and lateral
directions, taking the longitudinal direction first in the way I will now describe.
I provide the blocks ¹³, holding the flat in position, with catches el e³ of
which e turns or balances on a pin or pivot e³ and is formed with an oblique
surface e on its under left portion, whilst its right side tapers and is formed into a
hook .
Against the said oblique under surface e is inclined a pressing leverf fixed by
meaus of a pin in a guide frame f' in such way that pressure on said lever forces
the left end of the catch et upwards, and, consequently, the right end or hook e
downwards, causing the latter to engage with and pass through the fillet so as to
hold same fast. The guide frame mentioned is firmly screwed or otherwise
tastened to the frame of the machine.
The function of the second catch is to enable the fillet to be pressed against
the flat, and, at the same time, to stretch said fillet lengthwise.
Said catch is pivoted on to the pin e and is provided on its left side with a
hook e for holding a cord e*. A pulley is also fastened on the said pin e for
guiding said cord. A prolongation or projecting part of the frame (fo) is provided
with notches (1) and serves as guide for a double lever ('2) pivote at (f',) and

page_text: held in position by a spring (f). On the upper half of the lever (f',) is a hook (ƒ),
(Fig. 9), which is connected by a rope (8) running over the pulley (e), with the
hook (e) of the catch. On the lever (f) a pawl (f) is also arranged. In order to
lay the fillet on the flat, the lever (2) is pulled by hand towards the left in the
direction of the arrow, whereupon the spring (1) becomes stretched and the
pawl () falls simultaneously into one of the notches (1), the lever (f¹₂) being
thus held in a fixed position.
The fillet is now pushed under the hook (el) and the pawl (f) released, where-
upon, in consequence of the contraction of the spring (*), the lever (f) is drawn
back into its original position, thereby stretching the cord (es) and pressing the
hook against and drawing the fillet which is thus stretched longitudinally in the
direction of the arrow.
Having stretched the fillet lengthwise as above, I stretch same laterally as
follows:-
I first of all perforate the fillet along its right side, by means of any suitable
tool, in such way, that the perforations correspond with the holes in the flat
underneath; I then lay on the fillet one of the steel holders or strips (9) (as shown
in Figs. 11 to 14) in such way, that the tongues, (g') of same pass through the fillet,
through the hole in the flat and project underneath said flat, the side edge of said
steel strip meanwhile projecting somewhat over the side edge of the fillet as shown
in Fig. 15.
In order that this position of the steel strip (g) may be sufficient to firmly hold
the fillet, the tongues (9') of said strip are made broader above than the diameter
of the holes in the flat. After fastening the fillet on the right side of the flat
as described, I stretch the former laterally by means of the following arrangement;
above the bed on which the flat rests is a cover-like pressing and stretching
device. (Figs. 1 and 10). Said device consists of a gun metal bar (h³) on which
is fastened, by means of screws (*) a steel plate (7), having a notched edge or
teeth (¹).
Each end of the metal bar (*) is pivoted on to a swivel pin (1) fitted in the
frame, and, by means of which, the pressing and stretching contrivance can be
raised to enable the flat (a) with its fillet () to be placed in position on the bed
plate (6). The bar (2) has at each end an arm (h) provided with notches (4)
and passing through levers ('). Said levers (47) turning on pivots (2) are provided
with triangular pieces (48) (Fig. 10) which engage with the notches (4). A double
lever (¹) carrying a movable weight (i), is pivoted onto the frame at (2) and when
the stretching device is raised, is supported by its arm (3) resting against the
frame of the machine.
While the flat (a) is being laid in the bed-plate (b) and while the fillet (d) is
being laid on the same stretched lengthwise and secured on its right side by means
of steel strip (9) the pressing and stretching device is kept in a raised position
resting on arm (*).
After the flat (a) has been placed in position and the fillet prepared in the way
described, it is requisite to stretch the latter laterally in case it be narrower than
the flat. For this purpose the pressing and stretching device is lowered which
causes the steel plate (h) to engage with the left loose edge or side of the fillet (d)
(Fig. 10) and, by means of the teeth (/) of said plate, the fillet is held fast.
The lever () is then pushed on to the arm (/) which passes through the slo: (1)
said arm being pressed downwards by the weight (i) and the steel plate (4) thus
caused to press the fillet firmly against the flat. As is seen in Fig. 10, the metal
bar (3) is supported in slides (v') on guides (2) of the frame, said bar being
movable to and fro by turning the screw spindle (*) working in the female
screw (), by means of a hand-wheel (r). On turning the hand-wheel (v) the metal
bar (2) is moved laterally to the left and with it, the steel plate (/) holding fast
by means of its teeth (41) the fillet (d), the latter being thus stretched out laterally.
When the fillet is sufficiently stretched, it is perforated on the left-side in such way,
that its perforations exactly correspond to the holes in the flat (a) and is then

page_text: fastened by means of a steel strip (9), as in the case of the right side, being now in
the position shown in Fig. 15. It will be remembered that the upper parts of the
tongues (g) of the steel strips (9) are broader than the diameter of the holes
in the flat and that the fillet is firmly secured without the tongues (91) being bent
back after said tongues have been firmly pressed into position. When said tongues
are bent back therefore, there can be no danger of the fillet getting jerked out of
position the more so when the sides of the steel strips are also bent over at right
angles as shown in Fig. 15, since the fillet is not only firmly held from underneath,
but, also at the sides, which is an important advantage, in that the steel strips lie
in one and the same level with the side face of the flat.
For carrying out these operations, I provide a head (K) containing pressing
blocks as shown in Figs. 4, 5, 6, 7, and 8.
The under part of said head serves as matrix for the screw spindle or shaft (L)
which is driven by power transmitted through conical change wheels in the usual
way. When the work is begun, the head (K) is on the right side of the machine.
Said head consists of the under part (K') on which are arranged the supports (M M)
which slide in a dovetailed groove or bed. By means of a screw (N) (Fig. 5)
which works into a fixed matrix (N) the supports (MM) are moved to and fro by
means of a hand-wheel (N2). Into the head (K) are pushed slide arms (O) which
carry small screw studs (01) on which rotate rollers (O').
These
Through the action of a spiral spring (O³) the arms (0) are constantly drawn
inwards. The consequence of this is that the rollers (0) deflect the projecting
portions of the tongues (91) when the head (K) is moved to the left by turning the
screw spindle or shaft (L). On the supports (MM) are arranged the supports (PP)
which can be adjusted in vertical direction by means of screws (PP) and to
which supports are screwed clamping blocks (PP) (Figs. 5 and 6).
clamping blocks taper towards the end in order to deflect to a right angle the
projecting edges of the steel strips (g) on turning the screw shaft (L) and moving
the head (K) to the left, simultaneously with the bending back or deflecting of
the projecting portions of the tongues (91). (Fig. 15). For the sake of clearness
a clamping block is shown in detail in Figs. 5A and of which (Fig. 5A) is a
front elevation, Fig. 5" an elevation of the side of the block which engages with
and bends the projecting edges of the strip; Fig. 5° is a section on line y-y of
Fig. 5. From Fig. 5° it will be seen that the faces of the blocks form an
angle with each other which is somewhat less than 90°, for the purpose of bending
downwards the projecting sides of the strips.
In order to produce the steel strips or holders (9) having perforations corre-
sponding to the perforations in the flat and for the purpose of stretching and firmly
securing the fillet (d) on said flat, 1 employ the device represented in Sheets III
and IV of the drawings. Said device is mounted on the frame of the machine
already described and there driven by belt and pulley (R) or in any other way that
may be preferable, its essential features being the lever (R) which engages in the
recess or slot of the slide (R³), a catch (R) tapering towards the point and attached
to the pivot (R) of said slide (R) and which said catch by means of spring (R³)
is constantly pressed against the face of the flat (a) in such way, that, in the
forward movement of the slide (R³) said catch (R³) engages with the holes (a) of
the flat (a) and takes the latter with it. The lever (R) is pivoted on the bolt (R)
located in the bed-plate (t) so as to turn in either direction. The upper end of
the lever (R) is provided with a screw (R) and catches into an eccentric or
cam (T) (Fig. 23). When the shaft (W) is turned, the eccentric imparts to the
lever (R) and, consequently to the slides (R³) a to and fro movement in which
the flat (a) is worked forward a hole (a) each time the catch (R³) moves to
the left.
In order to move the lower end of the lever (R') and with it the catch (R$) back
to the right, the slide (R$) supporting the lever (R) is mounted on a fixed or
stationary bolt (S) and, after the flat has been worked forward a hole (a) is drawn
to the right again by the spiral spring (S) owing to the position of the eccentric (T)

page_text: The catch (R)
now allowing the upper half of the lever (R') to move to the left.
now engages in the next hole and the jerky forward movement of the flat is
repeated.
The flat (a) to which the strips are to be-attached is fixed between the cheeks (a³)
by means of screws (a¹) (Fig. 27^) and which cheeks slide on a square piece (a³)
having a groove (a) in which engages a screw (a³) so that a perfect and sure guide
action is obtained.
The square piece (a³) is screwed on to a block (a) fastened to the frame of the
machine. On the left extension of the square piece (a) rests a guide (a) for
the steel strip (R³) (Figs. 26 and 27) whereby the flat is firmly connected with
the strip (R) and the latter taken along with the same jerky motion as the flat.
On the shaft (W) near the eccentric (T) is keyed a second eccentric (W)
(Fig. 254) and the rotary movement of which imparts a to and fro notion to the
Said sliding strip (T¹) is
sliding strip (T¹) in the direction of the arrows 3 and 4.
connected with the press lever (T10) by means of spring (T) and has slots (t t¹)
through which project screws (t³ t) located in the bed-plate (6). Above the press
lever (T0) is located a plate (T") which is screwed fast to the bed-plate (*) by
means of screws (t° 7). On turning the eccentric (W°) the sliding strip (T1) and,
with it, the press lever (T1) are first moved in the direction of the arrow 4 where-
upon the pressing surface (8) of the press lever (T1) recoils from the pressing
surface (t) of the fixed plate (T") so that when the eccentric (W°) is turned
further, the steel band (R) guided between the pressing surfaces (tt) is gripped
and held by these latter just at the moment when the upper end of the lever (R)
has reached its furthest point to the right and when the catch (R³) has jerked the
flat a hole forward. Simultaneously with this operation comes into action the
punching device which will be hereafter described and punches a tongue (g).
On the shaft (W) is an eccentric (Y) (Fig. 25) with which the lever (Y¹)
(Figs. 19 and 20) which is screwed on to the shaft (Y2) comes in contact. Said
shaft (Y) is supported in bearings (Y') and carries the punch block or matrice (Y³)
with the punch (Y). When the eccentric (Y) has reached its highest position,
causing the upper end of the lever (Y¹) to press upwards, the punch (Y4) engages
with the steel band (R) while the latter is momentarily held stationary and cuts a
tongue (9) out of same, since by the upward movement of the upper half of the
lever (¹) a downward motion is imparted to the punch block or matrice (Y³)
and the punch engages with the steel band (R2) from the left to the right as shown
by arrow 5.
As will be seen from Figs. 17, 19, 194, and 20, the punch (Y) has a bevelled
cutting edge (Y) whereby the tongue (9) after having been cut or, punched is
simultaneously bent outwards forming an angle of about 40 to 60° with the steel
band (R) (Fig. 17).
The press lever (X') actuated by the eccentric (X) (Fig. 24) now enters in
operation; its spur (X2) penetrates above the perforation which has just been made
and near the tongue (g) whereupon the latter is brought into a vertical position on
the steel band as the tongue (g) slides up the oblique surface (3) of the spur (X³).
The press lever (X') is drawn back again by a spiral spring (X).
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
