SEWING-MACHINE GUIDE.

SPECIFICATION forming part of Letters Patent No. 716,117, dated December 1902- Applioation filed April 12, 1901. Serial No. 55,509. (No model.)

I with for sewing certain'forms and shapes in knit underwear; and the object of the invention is to provide a suitable revolvingguide,

which is fitted and fastened onto the bed or cloth plate of the sewing-machine.

The invention consists, primarily, of a revolving guide arranged to turn on the bed of a sewing-machine in proximity to the stitching and feeding mechanism thereof. In the form in which I have illustrated my invention in the appended drawings the revolving guide consists of a circular plateembedded in a recess in the bed-plate of a sewing-machine and turning on a hub or central trunnion, and this is used in connection with mechanism for stitching fabrics which are guided by said revolving guide, and said stitching mechanism may be arranged for plain stitching or for'faucy zigzag or embroidery, or it may be for any form of stitching'for sewing and attaching two or more layers of fabric together. As hereinafter set forth, the revolving guide is provided with sharp-pointed pins, which project above its surface for the purpose of holding the cloth which may be impaled thereon, so that as the feed mechanism of the sewing-machine feeds the fabric in the process of sewing the fabric is turned on therevolving guide,and thestitching isitherefore made in a curved line conforming to the movement of the revolving guide.

Having generally set forth myinventi'on, I will now refer to the'appended drawings, in which- I r Figure 1 represents a perspective view of a sewing-machinewith my invention applied thereto. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is a plan view of the bed-plate with the rotatable or revolving guide and feed mechanism removed. Fig. 4 is a perspective view of my preferred form of revolving guide. Figs. 5 and 6 are perspec:

tive views, the first showing a shirt as the stitching is being commenced, and the second showing the circular stitching almost completed.

Referring now to the details of the drawings by letters, B indicates the bed or base plate of any form of sewing-machine through which works the usual feeding mechanism 61 and over which is the usual overhanging arm D, carrying the pressure-foot Eand needle-bar G, all of which may be of the usual or any desired construction.

The bed-plate B is provided with a circular opening or recess 0, and in this opening is rotatably supported a revolving guide A,

which is preferably provided with a central guiding-trunnion b and with impaling-pins a, as clearly shown in the drawings. The recess or opening 0 is-preferably provided with a supporting-frame comprising arms H H,

which are formed with a central opening 72, in which the aforesaid trunnion b fits as the revolving guide A rotates in the recess 0. It is obvious, of course, that this frame may be omitted and the revolving guide rotated on the rim 0 ofithe opening or recess 0.

The foregoing is a description of my simple invention, and as the operation is obvious from an inspection of Figs. 5 and 6, in each of which is shown a shirt impaled on the pins a, it will suffice to state that as the feed mechanism moves the shirt the latter is bound to move in a circular direction, of which the axis of the revolving guide A is the center. In turning around with this revolving guide A the shirt is caused to move until it makes a half-revolution, as shown in Fig. 6, when the stitching will be completely finished and the shirt may be removed from the machine.

I am aware that it has heretofore been proposed to sew hatcrowns by guiding them around an attachment which is separate from the machine and which is situated on the opposite side of the feed mechanism from the overhanging arm.

I regard my invention as essentially different from this, for the reason that it is not only far simpler and can be applied to any machine now in use, but as the revolving guide is situated underneath the overhanging arm the stitching may be run around the shirt, as shown in Figs. 5 and 6, without causing the complete shirt to pass underneath the overhanging arm, which of course is objectionable in practical sewing.

It is obvious that'chauges may be made in the form of my revolving guide without departing from the essential feature thereof, which is a rotatable guide located under the overhanging arm of a sewing-machine and in close proximity to the feed mechanism thereof, whereby an article may be impaled on the rotatable guide and be turned thereon by the movement of the feed mechanism.

In my copending application filed May 31, 1901, Serial No. 109,756,I have shown and described the revolving guide forming the subject-matter of the appended claims; but in said application the said revolving guide is claimed in connection with cutting mechanism which cuts a fabric as said fabric is guided by said revolving guide.

What I claim as new is- 1. In asewing-machine and in combination with the bed pIate, feed mechanism, overhanging arm and needle-bar thereof, a revolving guide supported by said bed-plate eccentrically to the needle and underneath said overhanging arm, in proximity to said feed mechanism, and means for holding a fabric on said guide, whereby an article may be secured on said rotatable guide and be turned therewith by the movement of said feed mechanism without passing under said overhanging arm, substantially as described.

2. In a sewing-machine and in combination with the bed-plate, feed mechanism, overhanging arm and needle-bar thereof, a revolving guide having impaling-pins thereon and embedded in the bed-plate underneath said overhanging arm and in proximity to said feed mechanism, whereby an article may be impaled on said rotatable guide and be turned therewith by the movement of the feed mechanism, substantially as described.

3. In a sewing-machine and in combination with the bed-plate, feed mechanism, overhanging arm and needle-bar thereof, arevolving guide fitting and turning in a recess in the bed-plate in proximity to said needle-bar and feed mechanism and having impalingpins thereon, whereby an article may be impaled on said pins and be turned with said rotatable guide by the movement of the feed mechanism, substantially as described.

GEORGE SCOTT.
