PIETRO GIOLINO, OF NEW YORK, N. Y.

GAGE FOR SEWING-MACHINES.

To aZZ whom it may concern:

Be it known that I, PIETRo GIoLINo, a citizen of the United States, and resident or the city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Gages for Sewing-Machines, of which the following is a specification.

The present invention relates to a sewing machine gage, that is to say to an attachment for sewing machines which is adapted to determine the line of stitches in relation to the edge of the work in stitching hems, tucks, plaits, or in doing similar work.

One of the objects of the invention is to provide a simple and efficient device of this type which can be readily applied to all makes of sewing machines, and one which can be manufactured on a commercial scale, or in other words one which is not so difficult to produce as to be beyond the reasonable cost of such an article.

Another object of the invention is to produce a gage which can be conveniently adjusted in relation to the presser foot of the machine so as to change or vary, at will, the distance between the line of stitches and the edge of the goods.

A further object of the invention is to construct the attachment in such a manner so that it shall be adjustable for use upon cloths of varying thicknesses, and irrespective of the fact whether the edge of the arti- 'cle being stitched runs on one or the other side of the presser foot.

With these and other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter fully described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claims without departing from the spirit or sacrificing any of'the advantages of the invention.

One of the many possible embodiments of the invention is illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of a presser foot with the attachment in position thereon;

Specification of Letters Patent.

Application filed October 24, 1913.

Patented Apr. 21, 1914:. Serial No. 797,071.

Fig. 2 is a plan view thereof; Fig. 3 is a plan view of the presser foot and the attachment, the gage plate of the latter being disposed upon the left-side of the presser foot; and Fig. 1 is a side elevation of the attachment.

Referring now to the drawings in detail, the numeral 10 indicates the presser foot of a sewing machine, adapted to be attached to a presser bar in the usual manner. In the lower portion of the shank of this presser foot is formed a transverse aperture 11 of square cross section, in which is slidably disposed a bar 12 of like cross section, said bar being adapted to be locked to the presser foot against movement in any desired position by a. set screw 13, that is carried by the presser foot and screwed therethrough so as to bear against the bar 12. The bar is provided upon each of its sides with a graduated scale 14: to enable the operator to properly and conveniently set the gage in a manner hereinafter to be described. To one end of the bar 12 is fixedly attached a gage plate 15, set in a plane at right angles to the longitudinal axis of the bar, so as to be held in a vertical plane. The gage is of oblong configuration, its edges running parallel to the sides of the bar 12, its corners 16 being beveled oil. The plate is eccentrically attached to the bar 12 in such a manner that the distances between its

edges

17, 18, 19 and 20 and the longitudinal axis of the bar 12 increase in the order named.

The operation of the device is as follows: The gage can be used upon either side of the presser foot, as clearly appears from Figs. 2 and 3 of the drawings. It is applicable, therefore, to work in which the line of stitches is to run parallel to a hem, tuck or plait, the edge of which is arranged upon either side of the presser foot. When it is not desired to use the gage, it can be quickly removed from the presser foot by simply loosening the set screw 13. When the attachment is in position upon the presser foot, obviously the lower horizontal edge of the gage plate acts as the guiding edge. For proper use, obviously that edge is selected which projects beyond the lower plane of the presser foot a distance which corresponds substantially to the thickness of the upper layer or layers of cloth or material which are to be sewn to one or more layers in forming hems, tucks or plaits. Inasmuch as the gage plate has four edges which are located at varying distances from the 1011- gitudinal axis of the bar 12 and since it can be mounted upon either side of the presser foot, obviously the attachment is adapted for use upon different kinds of work. After the operator has selected the properedge of the gage plate and placed the attachment on the presser foot, the said plate is adjusted in relation to the presser foot according to the size of the hem, tuck or plait which is to be stitched or according to the distance at which it is desired to place the row of stitches from the edge of the fabric. The bar is then clamped in the aperture by the set screw 13, so that the gage is securely held in an adjusted position. 7

It is obvious that, while herein an oblong gage plate has been described, a gage plate of any other polygonal configuration can be made use of, permitting it to be used upon as many kinds of work as it contains edges. The bar to which the gage plate is attached must obviously correspond in configuration to that of the gage plate, the latter being, of course, always eccentrlcally attached to the said bar.

Copies of this patent may be obtained for What I claim is 1. The combination with a presser foot having a horizontal polygonal aperture therein, of a bar slidably arranged in said aperture, the cross section of said bar corresponding to that of said aperture, a gage plate of polygonal configuration attached to said bar, each side of said bar being of the same width, the sides of said gage plate being disposed parallel to but at different distances from the planes of the sides of said bar, and means for fixing the position of said bar upon said presser foot.

2. A gage for sewing machines, comprising a bar of polygonal cross-section, and a gage plate of polygonal configuration attached thereto, each side of said bar being of the same width, the sides of said plate being disposed parallel to but at difierent distances from the planes of the sides of said bar.

Signed at New York, in the county of New York and State of New York, this th day of October, A. D. 1913.
