TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HASELTINE, of the "International Patent Office," Southampton Build-
ings, London, send greeting.

page_text: to grant unto me, my executors, administrators, and assigns, Her Royal
Letters Patent for the same, and have made solemn Declaration that it
has been communicated to me from abroad by James Franklin Kellogg,
of North Bridgewater, Massachusetts, and Edward Adams Cutler, of
Providence, Rhode Island, both in the United States of America.
NOW KNOW YE, that I, the said George Haseltine, do hereby declare
that the following Complete Specification, under my hand and seal, fully
describes and ascertains the nature of the said Invention, and in what
manner the same is to be performed, in and by the following statement,
reference being had to the accompanying Drawing forming a part of this
Specification :-
The Invention herein-after described relates to certain improvements
in tuck markers for sewing machines, and the several parts of the said
Invention will be described separately with reference to the Figures of
the Drawing exhibiting the same.
The first part of the said Invention consists in rendering the arm of
the marker adjustable vertically with relation to the bed plate, and also
in combining therewith an adjustable plaiting finger or inside gauge.
Figure 1 represents in perspective one of my improved tuck markers,
and is exhibited in connection with the top of a sewing machine table,
a bed plate, presser foot, and creaser wheel, to illustrate the manner of
its application; Figure 2 represents my tuck marker in vertical longi-
tudinal section; Figure 3 represents more fully the plaiting finger...
A represents a standard, provided with jaws and clamp screw, to
admit of ready adjustability to the edge of the sewing machine table';
B represents a cylindrical socket, open at both ends, for receiving the
marker arm,
which may be secured in any desirable longitudinal position
by means of a set screw, or its equivalent; C represents a pivoted
fulcrum attached to and forming a part of the socket B. A slotted car
of the standard A is fitted to receive this fulcrum, and the two are
connected by a stud or screw passing through both. The lower end of
the fulcrum is circular, and its edge being cut with spiral teeth may be
likened to a segment of a spiral gear wheel; D is a threaded or screw
shaft placed in the standard parallel with the face of the threaded
fulcrum directly beneath it, and so arranged that the threads of the
shaft engage with the spiral teeth of the fulcrum; E is a knurled wheel

page_text: attached to the shaft D, and is the medium through which the screw
shaft is to be turned, and the fulcrum C rocked longitudinally to and fro
on its stud; F represents the arm of the tuck marker. It should be at
least of sufficient length to extend from the .edge of the table to the
presser foot, and fitted to slide freely in the cylindrical socket B, in
Its operative end is provided
which it may be secured by the set screw.
with a creasing edge rising vertically to engage with the channel of the
creasing wheel. At its operative end it is also provided with a laterally
projecting car, through which a socket is drilled longitudinally parallel
with the arm for receiving the plaiting finger or inside gauge, which
may be secured in any desired position by means of a set screw in the
arm arranged to engage with the shank of the finger or gauge. G repre-
sents the plaiting finger or inside gauge. It consists of a single piece
of wire, of fine stecl, by preference, with its end slightly flattened and
taper, bent at a sharp right angle to the shank. The said shank is fitted
to enter a longitudinal socket in the end of the arm, and is secured in
any desired position by a set screw. The finger should be arranged to
point in the direction of the feed. The object of having the marking
arm adjustable vertically is, that the crease may be readily made sharp
or dull as desired, the same being accomplished by a great or little
pressure of the creasing edge against the creasing wheel, according to
the style of work being performed. A further object sought to be
accomplished in the vertical adjustability of the arm is to be enabled
thereby to construct a tuck marker capable of general attachment to
a variety of machines, compensating in a measure for the difference
between the face of the bed plate and the top of the table, also by the
vertical adjustability of the arm the space between its under side and
the top of the bed plate may be varied to admit of the free backward
passage of the plaited goods already stitched without their being brought
again in contact with the creaser. By means of the finger or inside
gauge in the end of the marking arm the plait is held smooth and
straight, securing a desirable uniformity in the width of the plait.
The second part of this Invention consists in combining an adjustable
finger having a vertical creasing edge with an elastic cushion attached
to an arm, which in turn is readily adjustable to the needle bar of a
sewing machine by means of a socketed holder, the parts being con-
structed as will be more fully described hereafter.

page_text: Figure 4 répresents in perspective the elastic cushion with its arm and
holder ready for attachment to a sewing machine; Figure 5 represents
the same with its mode of attachment to a sewing machine.
'
A represents a holder; it is made of cast metal by preference, on the
score of economy, and is provided with a recess or socket to embrace
the needle bar, to which it is secured by means of a set screw B. This
holder should of course be varied in its general form, and its socket
fitted to the particular style of machine with which it is to be used."
D represents the arm of the marker, its forward end is bent downward
at right angles. This arm is fitted to a longitudinal socket in the
holder A, to which the set screw C is fitted to engage with the arm and
secure it in any desired position. E represents the elastic cushion of
india-rubber, by preference, although a vulcanized article might serve
an admirable purpose. This cushion may be secured to the pendant end
of the arm D in any desirable manner. F represents the adjustable
finger, having at its end a vertical creasing edge H. This finger is
made longitudinally and vertically adjustable in a manner substantially
as described in the first part of my Invention. It is sustained by the
clamp G, which is secured to the top of the table by means of a clamp
screw.
The operation of this part of my Invention is as follows:- -The
holder A is secured to the needle bar of the sewing machine in the.
manner described. The finger with the creasing edge is adjusted longi-
tudinally to a proper distance from the needle, depending upon the
width of the tuck desired. The arm D is next. adjusted longitudinally,
so as to bring the cushion E. on a line vertically with the creasing
edge H on the end of the finger F, which is so elevated that when the
needle bar shall be at its lowest point of depression the creasing edge
shall be in contact with the cushion, and under such a pressure as will
crease or mark the fabric being sewn as it passes between the edge and
cushion by the intermittent blows of the cushion actuated by the move-
ment of the needle bar.
The third part of this Invention consists in an improvement upon the
apparatus shown in Figures 1, 2, and 3, and relates only to a device in
combination with the inside gauge and its supporting arm. previously
described in place of the set screw, for enabling the gauge to be more
readily and conveniently adjusted to tucks of different widths.

page_text: Figure 6 is a view in perspective of the improved tuck marker, with
the exception of its adjuncts, which when the apparatus is in use are
connected with the presser foot of the sewing machine; Figure 7 is an
enlarged view in perspective of so much of the apparatus as will show
plainly the said improvement; Figure 8 is a sectional view of a clamp
herein-after described.
The adjustable inside gauge G, whose arrangement with reference to
the arm F is shown at Figure 7, is connected at its near end in any
convenient way to the friction clamp A, Figure 8, which is the means
employed in place of a set screw for more readily adjusting the gauge in
position. This clamp consists of a strap a, shown in section at Figure 8,
a pad b, fitted to the contour of the arm F, and a yielding spring c, of
rubber or other elastic material, arranged to exert pressure upon the
pad, and by the friction upon the arm F so created hold the gauge at
any point desired. While I consider the form of the pressure clamp
shown in the Drawing to be the best and most convenient, other known
mechanical arrangements for causing friction to be applied to the arm F
may be employed as a substitute therefor without substantially changing
the combination of mechanical devices herein-after claimed. It is quite
evident that this mode of adjustment presents obvious advantages over a
set screw, and enables the operator to change the adjustment of the.
gauge with the greatest facility.
Having thus fully described the said Invention, as communicated to
me by my foreign correspondents, and shown how the same may be
conveniently and advantageously carried into practice, I claim,-
First. The combination with the arm F, Figures 1 and 2 (having the
creasing edge) of the longitudinally adjustable finger G.
Second. The combination with a suitable standard of the arm F,
Figures 1 and 2, having a creasing edge, and made adjustable vertically
in relation to the bed of the machine, substantially as described.
Third. In combination with the standard A, Figures 1 and 2, the
adjustable arm F, having the creasing edge and the longitudinally
adjustable finger G, 'substantially as described.
Fourth. The holder A, Figures 4 and 5, having sockets and screws for
attaching the holder to the needle arm, and for receiving and holding
the arm D in combination with the elastic cushion and with the

page_text: vertically and longitudinally adjustable creasing edge, all being con-
structed, arranged, and operating as. described.
Fifth. The combination of a pressure clamp A, Figures 7 and 8, witli
the adjustable gauge G and arm F of a tuck marker, substantially as.
described for the purposes specified..
In witness whereof, I, the said George Haseltine, have hercunto
set my hand and seal, this Fourth day of January, in the year
of our Lord One thousand eight hundred and seventy-one..
Witness,
