GUIDE FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 718,818, dated January 20, 1903.

Application filed January 9, 1902. Serial No. 89,026. (No model.)

To all whom it may concern.-

Be it known that I, MARY ELIZABETH CAMPBELL, a citizen of the Dominion of Canada, residing at Toronto, in the Province of Ontario and Dominion of Canada, have invented new and useful Improvements in Gording Attachments for Sewing-Machines, of which the following is a specification.

This invention relates to a sewing-machine cording attachment adapted for use with any sewing-machine; and the essential object is to provide a simple and effective device of this class capable of adjustment to accommodate any size of cord used, and thereby overcome the disadvantages heretofore resident in cording attachments which were of such construction as to require the use of separate corders for different sizes of cords.

The invention consists in the construction and arrangement of the several parts, which will be more fully hereinafter described and claimed.

In the drawings, Figure 1 is a perspective improved attachment applied to the latter.-

Fig. 2 is a side elevation of the improved attachment shown applied. Fig. 3 is a crosssection through a part of the attachment.

The numeral 1 designates a portion of a sewing-machine head of any type or form and wherein a needle-bar 2 and presser-bar 3 are operatively mounted. The improved cording attachment consists of a foot 4, which is removably secured to the presser-bar 3 and comprises a socketed head 5, having a rear extension 6, formed with a transverse slot 7. The head 5, and consequently the foot 4 as an entirety, is held in removable relation to the presser-bar by a clamping-screw 8, and in the rear end of the extension 6 is a clamping-screw 9 for adj ustably securing an element, forming a part of,

the attachment, in the slot 7. .The foot 4 comprises a depending forwardly-projecting arm 10, having an intermediate bend 11, with an inner curved bearing-shoulder 12, the bend 11 continuing into a horizontal blade 13 with an inner straight-edge 14.

Within the slot 7 a transversely-extending supporting-bar 15 is adjustably held by the clamping-screw 9, and secured to the inner end of said bar is an angular gage-bar 16, comprising a vertical member 17 and a forwardly-extending elongated horizontal member 18, which is normally parallel with the edge 14 of the blade 13.

The cord is arranged in the goods in the ordinary manner by first inserting the cord between two thicknesses of the goods and stitching down along one side of the cord, and the turned or folded goods inclosing the cord is then disposed close to the edge 14 of the blade 13 and caused to firmly bear against the shoulder 12, the latter being close to the plane of movement or reciprocation of the needle carried by the needle-bar 2, the gage 16 being adjusted in accordance with the distance apart the cords are to be placed and the size of the cord operated upon or to be inclosed within the goods. After the cord is arranged in the goods and disposed in relation to the attachment as just set forth the goods and cord are held until the needle strikes the inner portion of the roll, and the feed of the goods to the needle is then regularly carried on by the ordinary sewing-machine feed, the edge 14 of the blade acting to hold the roll of the goods in proper shape and operating in conjunction with the bearing-shoulder '12 to render the cording operation effective.

The gage 16 serves as a guide or marker relatively to the blade 13, and by moving the said gage the device is quickly adapted for use with different sizes of cords or cords having varying spaced relation.

The advantage of the improved attachment is that it can be applied to any form of sewing-machine and different sizes of cordscan be operated on by the single attachment, thereby reducing the expense of devices of this class, as well as producing a convenient attachment.

Having thus fully described the invention, what is claimed as new is- In a cording attachment for sewing-machines, the combination with presser and needle bars and a needle in the latter, of an extended flat foot having an inner straight edge and a shank having a projection above the horizontal plane of the foot and extend- I In testimony whereof I affix my signature ing inwardly beyond the said inner straight in presence of two witnesses. edge Md a gage havmg a member adJust' MARY ELIZABETH CAMPBELL.
