River Head, Clerkenwell, in the County of Middlesex, Gentleman, for
the Twention at is CERTAIN IMPROVEMENTO IN SEWING MACHINES
Sealed the 22nd July 1862, and dated the 25th January 1862.
PROVISIONAL SPECIFICATION left by the said Edwin Augustus Curley
at. the Office of the Commissioners of Patents, with their Petition, on
the 25th January 1862.
J, EDWIN AUGUSTUS CURLEY, of 4, Green Terrace, New River Head,
Clerkenwell, in the County of Middlesex, Gentleman, do hereby declare
the nature of the said Invention for "CERTAIN IMPROVEMENTS IN SEWING
MACHINES," to be as follows:-
The first part of this Invention relates to means by which I produce any
degree of elasticity which may be desired in the seam, while at the same
time and by the same means the sewing is made stronger, the fabric is less
weakened by the punctures of the needle, and a number of other most desirable
ends are attained. I use both the shuttle or lock stitch, and the loop stitch
in their several varieties and combinations, but for most purposes I prefer the
lock stich, I do not modify the manner of making the stitches, but I do so
modify the feed motion, or the motion of the needle, that the stitches may be
caused to incline alternately to the right and left of the general line of the
seam to any required extent, thus producing an elastic diagonal stitch. One
means of attaining this result is by a lever having a roughened foot at one
[Price 8d.1

page_text: end for moving the cloth while the other end bears against both the face and
the periphery of a wheel which has on its periphery an adjustable projection
corresponding to a similar projection on its face, which two projections working
against this end of the lever cause the opposite or feed end to move forward
with an inclination to one side, and then after its return to its original position
a corresponding contrivance on the wheel causes it to move forward with an
inclination to the other side. This diagonal feeding of the cloth will evidently
cause a degree of elasticity in the seam corresponding to the indirectness of
the stitches produced thereby. And as the seam has not to bear any longi-
tudinal strain it is plain that both the needle and the thread may be finer
than those ordinarily used. In sewing heavy fabrics the punctures madeclose
together, and in a straight line by a needle which is necessarily, coarse, have
a great tendency to produce the same result which is obtained by the per-
forations in a sheet of postage stamps. It is evident that this tendency to
weaken the fabric in the line of the seam will be materially lessened both by
the increased fineness of the needle which I can use, and by the position of
the punctures which it makes.
The second part of this Invention relates to uniting two selvages, or the
edges of two pieces of material, so as to present an appearance similar to the
over seam made by hand. For this purpose I attach to the feeding apparatus
a long knife edge to run between the selvages, and thus serve to guide
the two pieces of cloth; then feeding the cloth as in the first part of this
Invention, I cause the half stitches to be taken alternately on each side of
the knife edge guide, thus uniting the two pieces of material, and forming
a perfectly flat seam without lapping.
The third part of this Invention relates to sewing cord upon any material
for the purpose of ornament, or to increase its strength. For this purpose
I use a machine made according to the first part of this Invention, but I add
a contrivance by means of which I can pay out the cord so as to run in a
guiding groove in the feed motion itself, and then I adjust the machine so as
to cause the alternate half stitches to be taken on opposite sides of the cord,
thus firmly fastening it to the cloth or other material.
The fourth part of this Invention relates to guides for lapping, folding, and
hemming, and to give direction to the seam I modify them so as to fit them to
be attached to the feed, because with the elastic stitch they would have a
tendency to interfere with the proper feeding of the cloth if they were fixed
as usual.
The fifth part of this Invention relates to a modification of the first part
so that after every alternate step of the feed, the needle goes down outside,

page_text: the edge of the cloth remaining to receive in the loop of its thread two throws
of the shuttle to produce a sort of button-hole stitch or edge finish.
The sixth part of this Invention relates to means by which I attain a
greater certainty in feeding or paying out the material to be sewn, I accom-
plish this desirable end by feeding both from above and from beneath the
cloth at the same time, and by the same motion. This can readily be done
by means of a pair of long levers or pincers, which seize the cloth both from
above and beneath at the same time, and move it forward diagonally the
distance required for the length of the stitch.
The seventh part of this Invention relates to turning the work in any
required direction by means of the apparatus for feeding. For this purpose
the feeding contrivances may be made to turn ou ou axis perpendicular to the

fabric, and in a line with the point where the needle enters.
which may be obtained by hand or otherwise is entirely independent of any
other motion of the feet, and by it I can make sewing assume any pattern
desired.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edwin Augustus Curley, in the Great Seal Patent Office
on the 25th July 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWIN
AUGUSTUS CURLEY, late of 4, Green Terrace, Clerkenwell, in the County of
Middlesex, and now of No. 30, Wilmington Square, in the said Parish of
Clerkenwell, in the County of Middlesex, Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fifth day of January, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Edwin Augustus Curley, Her special licence, that I, the said Edwin
Augustus Curley, my executors, administrators, and assigns, or such others
as I, the said Edwin Augustus Curley, 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

dom of Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "CERTAIN IMPROVEMENTS IN SEWING MACHINES," upon the condition
(amongst others) that I, the said Edwin Augustus Curley, 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 saine 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 Edwin Augustus Curley, do hereby
declare the nature of the said Invention, and in what manner the
same is to be performed; to be particularly described and ascertained
in and by the following statement thereof, that is to say, reference being
had to the Drawings hereto annexed.
Figure 1, Sheet 1, is a back elevation of a sewing machine with my
improvements applied thereto; Figure 2 is an end view of the same; and
Figure 3 is a face view of the cam which gives motion to the feeding
mechanism.
"
A is the frame of the machine, and B is an arm of the frame which
contains the shuttle and shuttle driver, and which supports the cloth; C
is the driving wheel; D is the driving shaft; and E is the cam which
drives the needle and shuttle; F is the groove which gives motion to the
shuttle; the needle groove which is on the opposite side of the cam is shewn
in dotted lines. It will be seen, on examination of these grooves, that one-
half of each groove is the exact fac-simile of the other half, and conse-
quently each revolution of the cam produces two complete actions of the
needle and shuttle.
G is a fixed guard which protects the front face and the rim of the cam E;
H is what is commonly known as the rocking shaft; it is supported at the
ends by the screw I and the pin 11. That part of the screw I which enters the
shaft is smooth, and the supports I and I' allow the shaft to turn freely,
and also to slide endwise. The screw I also serves to regulate the distance
that the rocking shaft H can travel endwise, or to stop that motion entirely.
The projections J and J' on the end of the shaft H pass through slots in the
feeding leg K, as shewn more clearly at Figures 6, and they set over the out-
side of the leg so as to prevent its shaking or slipping out of place. The
arm L of the shaft H carries two set screws, marked M and N (Figures 1
and 2); M sets against the face of the cam O (Figures 2 and 3), and N sets
against its circumference. As the cam revolves with the shaft D, the incline
a.(Figure 3) is brought against the end of the screw M, and pushes it
towards the back of the machine; the set screw carries the arm with it, and
consequently the shaft H turns slightly on its bearings I and I¹. The feeding
leg K, partaking of its motion, goes backward in the same manner as the

page_text: arin L, and the foot K being roughened on its under surface, and pressing
firmly on the cloth, carries the latter backward with it; but at the same time
that the incline a presents itself to the screw M, the incline e on the circum-
ference of the cam presents itself to the screw N, and pushes the shaft H and
feeding leg K endwise or towards the left hand of the operator. Here we
have two impulses given to the feeding leg K at the same time, the one
directly backward or from the operator, the other towards the left hand; the
consequence is, that the foot K and the cloth moves in a diagonal between
the directions of the two impulses. When this motion ceases the needle
penetrates the cloth, and while it remains in the cloth the tappet G (Fig. 3)
on the boss of the cam () presses down one end of the lever P; this causes
the other end of the lever to cease pressing on the top of the leg K, and the
spring Q immediately lifts the leg; then the cam O having turned so as to
present the falling incline 6' to the screw M, the spring R forces the leg
forward till it presses against a stop, or the screw has reached the bottom of
the incline b¹. As the foot has risen from the cloth it does not carry the
latter with it in its forward movement; while the sunken portion c of
the cam O is passing the screw M the tappet G having passed the back
lever L, the india-rubber spring S pulls down that lever, and again presses
the foot K firmly against the cloth; the needle now rises before the
whole of the sunken portion C of the cam has passed the screw M; then
the incline A¹ passes the screw M, and forces the feeding leg K. backward
in the same manner that a did before, and at the same time the incline e¹
on the circumference of the cam passes the screw N, and the spring T forces
the feeding mechanism towards the right of the operator till the screw
rocks the bottom of the incline, or the screw I stops the motion by striking
against the bottom of its socket in the end of the shaft H. These two motions
occurring together are compounded, and the cloth is carried back from the
operator with an inclinatiou as much to the right as the last was to the left;
as these alternate right and left diagonals are continually repeated, they produce
a seam of zig-zag or diagonal stitches. The length and the inclination of
these stitches may be varied at pleasure by turning the screw M to regulate
the stitch lengthwise of the seam, and by turning the screw N to regulate the
width of the diagonal. By the above-mentioned means great elasticity is
produced, which can be increased in proportion to the inclination of the
stitches to the general line of the steam; stitches produced by ordinary
machines are very liable to break if they are used on a material that is in
the slightest degree elastic. Boots and shoes beautifully sewn by machines
often break the stitching from one end to the other when the leather has

page_text: stretched slightly in wearing. By the use of my machines flannels can be
sewn; the elastic stitch produced resembles the herring bone or stitch used
in sewing flannels by hand. The punctures of a coarse needle close together,
and in a straight line weakens some kinds of material very much, but this
will not be the case when the diagonal stitch is used, for the punctures do not
occur in one straight line, and a much finer needle and thread can be used,
thus reducing the size of the punctures..
Instead of producing the diagonal stitch by means of the cam O (Figures
2 and 3), I can use the cam shewn in Figures 4 and 5. When used, it
occupies the same position as the cam O. Like that cam, it has two pro-
jections and ¹ on its face, which work against the screw M, but it has also
two corresponding projections on its circumference to work against the
screw N; one of these latter is adjustable, being moved in towards the
centre of the cam by means of two set screws h¹. When it is in one position
the screw M may be turned back till it will no longer touch the raised
portions and i of the face of the cam; then the screw N being in its proper
position, the projections 1 and 2 will feed the material to be sewn towards
the left with the ordinary straight stitches. If the screw N were on the
opposite side of the cam, aud the spring T (Figure 1) on the opposite side of
the leg K, it would feed in the same manner-towards the right; this is of
advantage in sewing boots and shoes and tubular articles, as they can slide
lengthwise on the arm B, when they could not otherwise be sewn by a
machine.
If the projection on the cam be slid inwards, so as no longer to touch
the screw N, while the screw M is turned forward, so as to be acted upon
by i and ¹, it is evident that and i will produce a compound or diagonal
motion of the feeding foot, alternating with a simple or direct motion caused
by i. This makes zig-zag stitches, of which every alternate one is longer
than the other. It will be seen that if preferred, the circumference of the
cam O, may be composed of several rings side by side, of which the first
ring shall have projections precisely like those on the cam as represented,
the second ring having projections ou its circumference like those on the
circumference of the cam represented at Figure 4; the third with one projec-
tion like O, Figure 4, and so on to any number required, any ring of the cam
being brought to act on the set screw N, by sliding the cam further along the
driving shaft D. It will be also seen that if instead of the screw M, I had
two screws acting on the face of the cam on opposite sides of the shaft. D, I
could dispence with one of the projections i or i¹ on the face of the cam O,
for the projection would force the leg K (Figure 1) backward every time it

page_text: passed one or the other of the screws. To keep the sewing ata uniform distance
from the edge of the cloth to sew over seams, and for other purposes, I use
guides more or less specially adapted to my other improvements. I prefer to
make these guides in two parts, the one part which is in some manner attached
to the feeding machanism, so as to partake of its lateral motion, may be the
same for all of the guides. This part is shewn in Figure 1, and more clearly
by the top view, Figure 7, V is the plate of the guide. The leg K passes
through the slot p so as to touch its sides, two pins q and q¹ pass through the
head piece R of the machine, and attach the guide thereto. They allow a free
play of the guide to the right and left, but they prevent its moving in
any other direction. When the feeding leg K is moved to the right or
left, the guide plate V goes with it. This plate has two screw holes in it,
and the lower parts of the guides are attached by a thumb-screw r, which
goes into one or the other of these boles. s, Figure 1, is a guide plate,
which goes one side of the foot K, to keep the sewing at a uniform distance
from the edge of the cloth. The screw r goes through a slot in the guide S,
and the latter may be adjusted to any required distance from the seam.
Figures 8, 9, and 10, are respectively top, side, and front views of a knife
edge guide, which is attached to the plate V, in the same manner as S,
and goes in front of the needle, when two edges are united by a flat or over-
One edge goes on either side of the lower or knife edge part of the
guide. Figures 11 and 12 are respectively top and front views of a guide,
which goes in front of the needle, in the same manner as the last and makes
a lap seam. Figures 13 and 14 are the same, execpt in that the lapping
of the cloth is the reverse way. Figures 15, 16, and 17, are respectively
end, front, and top views of a binding guide. It is adjusted to any width of
binding, by a thumb-screw and slide, and the whole or any part of the bind-
ing is thrown on the top or bottom, by means of a set screw and slot in the
top part of the binder. Figures 18 and 19 are front and end views of a guide
for folding over the edges of two pieces of cloth, while they are united as
shewn in Figure 20. Figures 21 and 22 are edge and top views of a guide
for braid, ribbon, or tape, when it is required to sew it at some distance from
the edge of the cloth.
seam.
Figure 1, Sheet 2, is a back view of a machine with my improvements,
and Figure 2 is an end view of the same. This machine is a modification
of that shewn in Figures 1 and 2, Sheet 1.
A, B, C, and D, are respectively the frame, the arm of the frame
which carries the shuttle, the driving wheel, and the driving shaft of the
machine, as in Figures 1 and 2, Sheet 1; E is the needle and shuttle cam;

page_text: F is the shuttle groove, and F¹ is the needle groove. An inspection of these
grooves will shew that the cam must perform an entire revolution to cause one
complete action of the needle and shuttle. I wish the needle to penetrate the
cloth, and return twice, while the feeding foot goes to the left and back, it
is necessary therefore that I should introduce the cog wheels W and X. W
has twice as many teeth as X, consequently its shaft D¹, and the cam O'
thereon, turns round once while the driving shaft D and the cam O is turning
round twice. There are two inclines on the face of cam O; at the same
time that the rising incline on pushes the screw M and the feeding foot K
backwards, the projection on the circumference of the cam O of which a face
view is shewn at Figure 2, pushes the screw N, (Fig. 1,) and consequently
the feeding foot to the left. This feeds the cloth in a diagonal between the
backward impulse given by the cam O and the impulse to the left caused
by the cam O. By the time that the cam O has made a complete revo-
lution the cam O' has passed half way round, and its falling inclineallows the
spring T to push the feeding foot to the right, at the time that the rising
incline on the cam O gives an impulse backward. This feeds the cloth
in a diagonal inclined as much to the right as the last was inclined to the
left. It will thus be seen that the cams 0 and O', in Figure 2, Sheet 2,
together perform the same functions that are performed by the single cam O,
Figures 2 and 3, Sheet 1. It will also be seen that as the shaft D', Figures 1
and 2, Sheet 2, turns round once, while two complete actions of the needle
and shuttle are taking place, I can dispense with cams on the shaft D, rising
instead on the shaft D' any of the cams described with reference to the
Drawings in Sheet 1. I am also able by changing the relative rates of revo-
lution of the,shafts D and D', or by altering the needle and shuttle cam E,and
by modifying the cams on the shaft D, to produce a repetition of two diago-
nals, and a back stitch of two diagonals and a forward stitch, and of many other
combinations which make a highly ornamental seam The leg K, in Figure 1,
Sheet 2, is shewn more plainly in Figures 3 and 4; Figure 3 is a top view,
and Figure 4 a view partly in section through the line A, B, of Figure 3. The
upper part of the leg K is round and passes through the arm J of the rocking
shaft H. The .lower part of the leg is flat, and works in a slot in the
arm J, which prevents its turning round. The helical spring Q, working in
a chamber in the arm J, lifts the foot whenever the lever P, Figure 1, rises
from the top of the leg. The upper guide plate V, Figure 1, works on two
screws at the back of the head piece. It has two pins or projections one
on either side of the arm J, which move it to the right and left with the
foot k. Figure 5 shews a modification of the rocking shaft H, and the

page_text: feeding leg K. The helical spring Q lifts the leg which rises freely through
the lower collar and through the end of the shaft H. The lower collar is
fastened to the pin J by a set screw, and the upper one is fastened in the
same manner to the leg, and passes freely up and down on the pin J. By
these means of fastening the collars the leg is prevented. The shaft is
moved to the right and left in its bearings in the same manner that it is
moved on the screw and pin I, Figure 1. Figure 6 is another modi-
fication of the leg and shaft; aud Figure 7 is another view of the leg, show.n
in Figure 6. The pin' I' on 'the end of the shaft goes through its bearing and
impinges on the side of the leg. The upper part of the leg is held in its place
by the spring T; a screw goes through a slot in the lower part of the leg into
the arm J of the shaft H; the motion of this leg is like that of the others.
Figure 8 shews on a smaller scale a method of feeding the cloth, both
from above and beneath. The two arms H and H slide right andi left by
springs T and T, and by the action of a cam-against the set screw-N.
The action of another cam: against the set screw M causes. their back-
ward and forward movement on the pivot' I, shewn in Figure 1. From the
connection of the two arms; the feeders Kand K', have the similar motions,
right and left, and the backward and forward. They are pressed against
the cloth by levers at P, Figure 1. I prefer this double feed motion in
sewing very heavy articles, because the two roughened: surfaces of the
feeders will hold the material much more firmly than one such feeder
would hold it against a smooth surface. Figure 10 is a top view of the
under feeder. The needle passes through the hole, and a knife edge guide
which is attached to the upper feeder "when an over seam is required.
The stops on the sides of the feeder go against the bottom of the cloth
plate, and prevent the feeders rising too high. As the under feeder need
rise but very little, it can pass over the shuttle, which must be slightly
lowered to enable it to do so.
Fig. 1, Sheet 3, is a view partly in section of a sewing machine having'an
under feed with my improvements attached thereto. A is the cloth ;-Bis
the driving wheel; C, the driving shaft; D, the needle cam, which causes
two complete actions of the needle to one revolution; E is the shuttle cam;
F, the shuttle driver and holder; G, the shuttle; and. H is the feeder, The
needle passes through a hole in the feeder, and the latter passes over the
shuttle; I is a spring which holds the feeder: H against the projection Jon
the face of the cam K. This spring and cam give the alternate right and left
movement. The cam has two projections or tappets on its circumference,
which lift two tappets at Lawith the spring: which holds the feeder against

page_text: them produce the backward and forward movement of the feeder. The
amount of lateral action as well as the amount of the backward and forward
action is regulated by a thumb or screw. There are two complete actions
backward and forward to one complete action right and left. If the needle and
shuttle did not perform two complete actions to one revolution of the driving
shaft, it is evident that I could not produce the lateral movement directly
from the driving shaft, but I could readily produce by the intervention
of a pair of cog wheels as W and X (Fig. 2, Sheet 2. By modifying
the cams I can produce any motion of the feed which I have described in
reference to the other Figures of these Drawings. The guides which I rise
attach to the feeder H. Figure 2 is a top view of a portion. If instead of
the feeder H a wheel feed is used, I cause the projection J on the cam K
to work against the end of the shaft of the feeder, and the lateral move-
ment is produced as before described of another machine with my improve-
ments attached. A is the plate; B and B¹ are uprights, which support
the shaft C. This shaft is turned by a belt from the treadle wheel to the
pulley D; E is a rod or lever, which works on an excentric on the shaft C,
and gives motion to the needle lever; and F is the feeding bar. The feeding
bar is held up against the cloth by a projection on the circumference of the
cam G, at the same time that it is moved forward in the direction of the
arrow by a projection on the face of the same cam. This moves the cloth
forward. The spring H throws the feeder away from the cloth when the
stitch has been taken. The cog wheels I and J turn the cam K once round,
while the cam G is making two revolutions. A projection on this cam, as
.seen at Figure 9',throws the feeding bar F laterally in one direction by pushing
against the end of the arm L, and a spring M, Figure 5'), by pressing against
the same arm throws the feeder laterally in the other direction when the pro-
jection on the cam K has passed the arm L of the feeding bar F. The length
and direction of the stitches are regulated by screws or by inclines as in
Figure 3. Figure 3 is a reverse view of the cloth plate, and feeding
mechanism of a sewing machine; and Figure 4 is a back view of the parts
beneath. A is the cloth plate, the cloth plate, in both Figures B, B¹, etc.,
are the uprights; C is the shaft; D (Figure 4) is the driving pulley; F is
the feeder; I and J are the cog wheels (Figure 4), which move the cam K.
This cam gives to the slide La lateral movement in one direction, and the
spring M' forces the slide L in the opposite direction when the projection
on the circumference of the cam K has passed the nose of the slide L.
The slide L is supported in bearings at N, N', and N°. The feeder F slides
backwards and forwards between the two arms of the slide L, and the forward

page_text: motion of the feeder taking place at the same time with the lateral movement
of the slide L to one side, causes the cloth to be fed in a diagonal inclined to
that side, and the next forward movement of F taking place at the same time
with the return of the slide L, causes the cloth to be fed with a similar incli
nation to the other side; L' is a support for the various guides which may
be required; N is an incline, which regulates the length of the stitch by
stopping the rear end of the feeder F; and O is another incline which regates
the lateral movement by stopping the slide L. Figure 6 shews a knife edge
guide which is attached to L' when an overseam is required. Other guides
can be attached in the same manner, or by a set screw. Figure 7 shews
the manner of vibrating the needle to produce a diagonal stitch. A is the
frame of the machine; B is the head piece; and C is a bar working to the
right and left on the pins D and E. On the other side of the bar C is an
arm C', which is fastened to the frame A by a set screw in the slot C. It
is also fastened to the rocking shaft by the H (Figure 1, Sheet 1), by the
pin F (Figure 7), which goes through the opening shewn in the frame A,
and attaches to the shaft H, which with the spring I gives to it any lateral
movement it would otherwise give to the feeding foot k (Figure 1, Sheet1)
When I vibrate the needle I do not attach the rocking shaft H (Figure 1,
Sheet 1), to the feeding foot, but I pass the projection J behind the leg K
which has no lateral movement. I will be seen on inspection of the Figures,
that instead of using the rocking shaft H for producing the lateral movement
either of the needle or of the feed, I can use an independent bar, which shall
have the right and left movements of the rocking shaft, whilst the latter
has but the ordinary rocking movement which it has in other machines.
Figure 8 is a corder, having holes for various rigid cords. It is attached
to the guide plate V, Figure 1, Sheet 1); Figures 9 and 10 are side and
front views of a guide for sewing on binding as cord. The pins A and A¹
go into the top of the head piece B, Fig. 17, and the bottom C of the guide
stands in front of the needle, and at a few inches distance. As the cord
passes through the hole in the corder the stitches are taken alternately on
the right and left of the cord, thus forming a sort of network over it.
Having now described the nature of my said Invention, and the means
of carrying the same into effect.
I claim the lateral movements of the rocking shaft H (Figures 1, 2, and 5,
Sheet 1, and Figures 1 and 2, Sheet 2, and the modification thereof men-
tioned in the foregoing description.
I claim the imparting a lateral movement to the feeder, or to the needle,
by means of an independent shaft or bar as described.

page_text: I claim the methods of attaching the feeding leg K to the rocking shaft H,
and the improvements in actuating the same, which are shewn in Figures' 1
and 6 of Sheet 1, and in Figures 1, 3, 4, 5, 6, and 17, of Sheet 2.
I claim attaching the various guides required in sewing to the feeding
mechanism, so as to partake of the lateral motion of the same substantially
as described.
I claim the various guides shewn in the accompanying Drawings.
I claim feeding the cloth both from the top and bottom, as shewn at

..my hand, and seal, this Twenty-fifth day of July, One thousand
eight hundred and sixty-two.
