COMPLETE SPECIFICATION.
Improvements in Sewing Machine Attachments.
I, ALICE LA GUAYRA MAYO, of Great Falls, in the County of Cascade, and Terri-
tory of Montana, United States of America, 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 sewing machine attachments.
The Invention has for its object to provide a device capable of use as a quilter or
as a gauge as occasion may demand, and which may be conveniently attached to the
presser bar of a machine and wherein when the attachment has been applied a portion
of the attachment will act in the capacity of a presser foot.
The Invention will be described with reference to the accompanying drawing
forming part of this specification, in which figure 1 is a plan view of the attachment,
figure 2 is a side elevation of same, and figure 3 is a side elevation of the presser
block or foot of the attachment. Similar figures of reference indicate corresponding
parts in all the views.
The presser block or foot, comprises a body 10, preferably rectangular in cross-
section, having at the inner end a needle slot or opening 11 which may be in the form
of a key hole, as illustrated, or of any other form, as demanded by the construction
of machine to which the attachment is to be applied. In one longitudinal edge of the
body 10, a recess 12 is also preferably made to provide a passage, for instance, for
the presser bar in its downward stroke. At each side of the recess 12, which is
ordinarily located centrally between the ends of the body 10, a standard 13 is
upwardly projected and at the upper ends of the said standards a sleeve 14 is
rigidly secured provided with a set-screw 15 which set screw is adapted to contact
with the presser bar when the latter is passed through the sleeve. In the upper face
of the body 10 of the presser foot or block at or near the outer end, there is a trans-
verse groove 16 adapted for the reception of a longitudinally slotted guide bar 17 the
slot in the guide bar being preferably located at or near the centre of the same and
extending virtually from end to end. Upon the upper face of this guide bar, at each
side of the slot, there is a scale 18 the scales being ordinarily made to read in reverse
directions. At each end of the guide bar 17 a gauge arm 19 is rigidly attached, the
said gauge arms being preferably secured to the under face of the guide bar and
extending at a right angle therefrom parallel with the longitudinal axis of the presser
foot or block, as best illustrated in figure 1. The guide bar is held in contact with
the presser foot or block by a set or thumb screw 20 which passes through the slot in
the guide bar into the body of the presser block or foot.
To secure the attachment to the machine the presser bar is passed downwards
through the sleeve 14 of the presser foot or block aud the latter is held in rigid
contact with the former by the set screw 15.
It will be observed that when this presser foot or block is thus attached to the
presser bar, it is capable of performing all the functions of an ordinary presser foot.
In the operation of quilting, by loosening the set screw 20, the guide bar may be
carried either to the right or to the left until the necessary gauge is acquired, where-
upon the set screw is screwed to firmly clamp the guide bar to the presser foot in such
position. The further operation of quilting is the same as is followed when the
ordinary well-known form of quilter is employed.
The attachment, it will be readily observed, may also be used as a gauge, dispensing
with the ordinary gauge usually secured to the bed plate of the machine; and by
reason of the two arms 19, the device is capable of convenient use either from the
right or from the loft

page_text: When the device is attached to the presser bar of a machine it may be used, if
desired, at all times in place of the ordinary presser foot, as a gauge is ordinarily
necessary or desirable in all classes of machine work; and if a gauge is not absolutely
necessary, the guide bar and arms are not, at least, in the way of the operator, while
if the operator so desires the guide bar may be expeditiously detached from the pressor
foot or block, by simply removing the set-screw 20.
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 ;
1. An attachment for sewing machines, consisting of a presser foot or block pro-
vided with a rear extension or heel, for the purpose specified.
2. The combination, with a presser foot or block having a rear extension, of a gauge
or guide bar held to slide upon the said extension, substantially as shewn and
described.
3. The combination, with a presser foot or block having a rear extension, of a guide
bar held to slide upon the said extension and provided with a gauge arm or arms, sub-
stantially as shewn and described.
4. The combination, with a presser foot or block adapted for attachment to the
presser bar of the machine and provided with a rear extension, of a longitudinally
slotted guide bar held to slide transversely upon the extension of the presser foot or
block, an arm integral with one or both extremities of the guide bar, and a set or
thumb screw clamping the guide bar to the presser foot, substantially as and for the
purpose specified.
5. The combination with a presser foot or block provided with a side recess, a
sleeve supported above the said side recess adapted for the reception of the presser
bar of the machine, and a needle slot or opening in the forward end, of a longi-
tudinally slotted guide bar held to slide transversely across the presser foot or block to
the rear of the sleeve and provided with a scale or scales thereon, and a gauge arui or
arms projected at a right angle from the said guide bar parallel with the longitudinal
axis of the presser foot or block, all combined for operation, substantially as shewn
and described.
