SEWING-IVIACHINE FOR TUCKING.

SPECIFICATION forming part of Letters Patent No. 664,975, dated January 1, 1901..

Application flied March 5.1900.- serrano. 7,394. (Nomerie.)

To @ZZ whom t may concern:

Beit known that I, JOHN BUoKLEY SEEL, a subject of the Queen of Great Britain and Ireland, and a resident of 59 Chapel street, Great Ancoats street, Manchester, county of Lancaster, England, have invented certain new andusefullmprovementsin Sewing-Machines for Tucking, (for which I have filed application for British patent, No. 2,953, dated February 14, 1900 5) and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to the combination, with a sewing-machine, of means for forming tucks in or on textile fabrics.

Figure 1 is a side elevation. Fig. 2 is a plan. Fig. 3 is a cross-section on was of Fig. 2. Fig. 4 is a plan to illustrate the formation of the fold. Fig. 5 is a front elevation showing the action of the gage or guider.

An ordinary sewing-machine A (indicated by dotted lines in Fig. 1) is used, preferably in an inverted form, and secured to one of the uprights of the stand B by a screw ct. The needle and presser-foot are then underneath, while the looper b is at the top. A cover-plate as is held to the needle-plate a2 by screws a6, passing through spiral springs in compression between the cover-plate @Sand the needle-plate a2, so that by turning the screws the distance of the cover-plate from the needle-plate a2 may be varied to suit fabrics of different degrees of thickness.

The cloth in which the tuck is to be formed 1 is folded over the tongue c of the plate c,

which is then slid forward, so as to bring the fold past the sewing-line a5 of the needle. The distance a4 from the point of the tongue c to the sewing-line ofthe needle determines the depth of the tuck. The cloth is fed past the needle in the direction of the arrow in Fig. 4. The part of the needle-plate just over the tongue c', where the plait is formed to make the tuck, is cut away, as shown in Fig. 4.. A drag pin or peg d, passing through the cover-plate a3 and the needle-plate a2, puts a slight drag on the cloth and by keeping it taut on the tongue c contributes to more perfect work and straighterfeeding at high speeds. The drag-pin d is set nearer to or`farther from the tongue c', according to the depth ot' the tuck to be formed. Several pegholes are provided to enable this adjustment to be lnade. The tuck is first formed over the point of the tongue c. When the tongue is slid forward in the position shown in Fig. 4, the part of the fabric between d and the tongue will be subjected to'frictionol` drag, which will be greater or less, according as the pin dis nearer to or farther from lthe tongue.` The plate c is mounted in fixed guideways, in which it may be slid longitudinally by the lever c2. One of the guide-bars c3 is graduated to enable the plate to be readily set for any depth of tuck. An important feature of the invention is that the plate c and itsfixed carrying-guides are mounted in such a manner as to be detached from the sewing-machine proper-as, for example, on a separate.

ing appliance the cloth canhang or freely fall down under the table of the machine as the work proceeds both before and after the formation of the tuck. To prevent the cloth fouling the needle-bar or presser-foot when an inverted machine is used, a shield-plate s is carried by a lever CZ', having its fulcrum at d2 under the table of the machine. When sewing is proceeding, the shield occupies the position shown in Fig. 1. When it is desired to gain access to the needle-bar, the shield s is swung outward away from the needle-bar. After the rst tuck is formed the distance apart of the succeeding tucks is determined by a gage or guider e. This consists of two thin plates of metal, which may be set at Varying distances apart by means of set-screws.

It is carried by a lever or arm e', carried by back to the left about its hingepin e2. The last tuck made is inserted between the plates of the guider e, as shown in Fig. 5, and as the Work is fed forward this tuck acts as an automatic guider or gage for insuring the parallelism of the tuck actually being made with the one previously made. llarkingz-lines or other devices of a like nature for a similar purpose are thus unnecessary. The distance of the guider e from the sewing-line of the needle determines the pitch or distance apart of the tucks, and by sliding the plate e4 any desired pitch may be lobtained.

Vhat I claim as my invention, and desire to secure by Letters Patent, is-

1, For forming tucks in textile fabrics the combination with a sewing-machine of the adjustable cover-plate d3 the drag-pin d and the longitudinally-adjustable tongue-plate c, the latter mounted in fixed guideways detached from the sewing-machine proper at its operative part so as to present no obstacle to the hang 0r fall of the fabric in front of and to the rear of the sewing' mechanism substantially as set forth and shown.

2. For forming tucks in textile fabrics the combination With a sewing-machine of the adjustable cover-plate a3 the dragpin CZ the longitudinally-adjustable hinged guider or gage e and the longitudinally-adjustable independently-supported t0ngue-plate c, substantially as set forth and shown.

3. For forming tucks in textile fabrics the combination with an inverted sewing-machine of the shield s the adjustable coverplate a3 the drag-pin d the guider or gage e and the independently-supported longitudinally-adjustable tongue-plate c substantially as set forth and shown.

In testimony whereof I hereunto alix my signature in presence of two Witnesses.

JOHN BUCKLEY SEEL.
