Specification of Letters Patent.

T 0 all whom may concern:

Be it known that I, WILLIAM MILLER,

citizen of the United States, residing at De-- troit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Markers for Sewing-Machines, of which the following is a specification.

In the operation of sewing machines, and more particularly those driven by power and used in upholstery and the like, it is desirable to provide a marker which will define a line for stitching at a desired distance from the path which'the needle is at that time traversing,

This invention relates to markers for sewing machines and to an arrangement thereof whereby a very legible line is traced on the fabric in such a manner that the fabric itself is not retarded while the operator can readily re-adjust the device and set it at any desiredpoint.

The invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

In the drawings Figure 1 is a view in front elevation of a sewing machine head provided with a marker that embodies features of the invention;

Fig. 2 is a plan view of the head and marker;

Fig. 3 is a view in end elevation of a modification of the marker;

Fig. 4 is a view in detail showing the clamping means of the modified form; and

Fig. 5 is a view in detail of another binding or clamping means.

As herein shown in preferred form the cover plate 1 of a sewing machine head affords detachable support for a gage member or rod 2 that is thereby held transversely to the path of feed of the machine. A clip 3 is angularly adjustable and longitudinally shiftable on this member which may be graduated as indicated at 4, if desired. As herein shown in Figs. 1 and 2 the clip is merely a slotted block with a clamping stud 5. An extension 6 which is preferably a channel in cross-section, affords a pivotal support for a stylus arm 7 Preferably the stylus arm is likewise of channel section with ears 8 embracing the member 6 and a pivot pin 9 passing therethrough. A marker member or stylus 10 is frictionally held in the member 7 so as to bear obliquely against the upper surface of fabric 12 passing through the machine.

A spring arm 13 passes between the ears 8 of the member 7 so as to have a rocking bearing against the stylus arm 7 or, more properly, the stylus 10, while the upper end portion is confined by a thumb nut 14 that is adjustable on a tension screw 15 secured to the member 6. The outer end portion 16 of the arm is free to take any position that it tends to assume under variable positions of the member 7 due to irregularity of the fabric 12 which the stylus is traversing.

As indicated in Figs. 3 and A adjustment of the clip longitudinally of the stud may be made by forming the clip as indicated at 17 with a slotted opening through which a screw-threaded portion 18 of the gage rod 19 passes, the latter being flattened and a feather 20 being inserted to prevent rotation of the clip. A ratchet plate 21 is pivoted on a pin 22 in the slot in engagement with the screw threaded portion of the gage. A stop 23 engages a segmental slot 2 k in the plate 21 to limit the throw of the latter-there being a pluralit of apertures 25 in which the stop may e inserted. By throwing this segment or ratchet plate to one side orthe other by means of a thumb part 26, the stylus may be rapidly shifted into either of two predetermined positions.

Or, as indicated in Fig. 5, a gage rod 27 may have adjustable stop collars 28 with a slotted clip 80 that carries the stylus and is itself held by a se mental clamp plate 31 eccentrically pivoted on a pin 32 so that it binds against the gage rod as desired.

As a result of this construction, a marker is obtained that has an angle of contact so oblique to the fabric that it does not tend to pull or draw the fabric while the spring tension may be varied as desired for the stiffer materials used in certain kinds of upholstery.

Obviously, changes in the details of construction may be without departing from the spirit of the invention and I do not care to limit myself to any particular form or arrangement of parts.

What I claim is l. A marker for sewing machines comprising a gage member secured transversely to the path of the feed of the machine, a clip angularly and longitudinally shiftable on the gage member and a spring pressed stylus holder articulated to the clip to oscillate in a plane transverse to the gage memher.

2. A marker for sewing machines co1n prising a gage member adapted to be secured to a machine transversely to the path of feed thereof, a clip angularly adjustable and longitudinally shiftable on the gage member, a stylus holder pivoted to the clip on an axis parallel substantially to the gage member and a spring arm having adjustable tension connection with the clip and rocking engagement with the stylus holder.

3. The combination of the cover plate of a sewing machine head with a gage rod secured to the cover plate, a clip angularly and longitudinally adjustable on the gage rod, a stylus holder pivoted to the clip to swing in a plane transverse to the gage rod and a spring arm having tensioned engagement with the clip and rocking contact with the stylus holder.

4. A marker for sewing machines comprising a gage rod, a clip on the rod, means for holding the clip in angularly and longitudinally adjusted position on the gage member, an extension on the clip, a stylus holder pivoted near one end to the extension transversely to the gage member, and a spring arm having rocking bearing on the stylus holder and adjustable connection with the clip for varying the tension of the spring arm.

5. A marker for sewing machines comprising a gage rod, a clip, means for securing the clip in adjusted angular position at any desired point on the rod, an extension on the clip, a channel-section stylus holder, a pivot passing through the sides of the channel and through the clip extension and a spring arm adjustably connected at one end of the clip in rocking engagement with the stylus holder.

6. A marker for sewing machines comprising agage rod, a clip onthe' rod, means for holding the clip in adjusted position angularly on the rod, a channel-section extension secured to the clip, a channel section stylus holder, a pair of ears extending from the flanges of the holder and embracing the clip extension to which they are pivoted, a tension screw on the extension and a spring arm apertured near one end to engage the tension screw and bent to pass between the flanges of the stylus holder against which it bears.

WILLIAM MILLER.
