ING-GUIDE FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 393,329, dated November 20, 1888.

Application filed January 15, 1887. Serial No. 2.24.485.

To all whom it may concern.-

Be it known that I, HAYMAN FREEDMAN, of the city of Rochester, in the county of Monroe and State of New York, have invented a certain new and useful Improvement in Tricking-Guides for Sewing-Machines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the drawings accompanying this application.

This invention relates to an attachment for tucking thick and heavy goodssuch as woolen 'cl0thswhich are made up into childrens garments, and is especially for use in childrens clothing manufactories. It is found that the ordinary plaiterssuch as accompany common sewing-machines for plaiting light goods-will not answer this purpose; hence it is the practice in clothing-manufaetories to do the work by hand, first marking the tucks with a measure, then folding and basting the tucks, and finally stitching, each operation being complete in itself.

It is the object of my invention to obviate these difficulties by producing a device by which the work can be done on a more expeditious, effective, and accurate manner.

In the drawings, Figure 1 is a plan view of the tucking attachment located in the bed plate of a sewing-machine, showing also a cross-section of the needle-bar and presser-foot. Fig. 2 is a side elevation of Fig. 1 looking in the direction of arrow 1,Fig. 1. Fig. 3 is a longitudinal section in line 00 :20, Fig. 1. Fig. 4 is a rear elevation of Fig. 1, enlarged, looking in the direction of arrow 2, Fig. 1.

A indicates the body of the device,the same consisting of a metal strap or plates provided at its left-hand end with a vertical flange, a, that forms a guide, and also provided with a longitudinal slot, 1), for the attachment of the gage-bar and attaching-bar, as will presently be described. The top surface of the plate A is laid .out in a scale of inches and subdivisions, as shown,

13 is a gage-bar, and C an attaehing-bar,both standing at right angles to the plate A, and secured thereto, on the under side by screws, on which are screw clamping-nuts d d. These bars are adjustable laterally on the plate A to any desired position by simply loosening the (No model.)

passes a thumb-screw, f, to attach the bar fast to the bed E of the sewing-machine, which is always provided with a hole to receive the screw. This hole in the bed is at different places in different machines, and the object of the holes in the attachingbar, and also of the lateral adjustment of said bar on the plate A, is to fit the said bar to the different positions of the hole in the plate, and also to bring the flange a in proper relative position with the needle G and prcsser-foot H. The object of adjusting the gagebar B laterally is to produce different widths of tucks, as will presently be described. The square edge of the gage-bar next to the needle serves as the shoulder or guide for the folded edge of the cloth to run against.

The operation is as follows: The left-hand edge of the cloth is first folded over, and then stitched up simply to forma rib, j, as the starting-point of the tucking. This rib is placed outside of and against the vertical guide-flange a of the tucker. The gage-bar B is then moved inward or away from the needle a distance equal to the desired width of the tucks previously determined on. The loose end of the cloth is then doubled under and turned back toward the left, which makes a fold in the cloth. In this condition the cloth is run through the sewing-machine, the ribj, previously formed, running against theflange a,and the loose folded edge of the cloth running against the edge of the gage-bar B. The needle passes through the double folds of cloth intermediately between the rib and the folded edge, as shown. This forms the tuck, which is then turned up and is moved outward, and forms the rib that runs against the flange a in forming the second tuck. In this manner the tucks are all formed in succession, one after another, working from the left to the right of the cloth. In ordinary tucking attachments now in use the tucks are made working from the right to the left. Very thick and heavy goods can be plaited by this attachment, which cannot be done by ordinary tucker-s used with sewingmachines.

In very heavy goods it is necessary to hold the'folded edge down in advance of the plate A, and opposite to the needle and presser-bar, so that the fold will keep in contact with the edge of the gage-bar B; otherwise the cloth will spring up at that point and lose its hold against the gage-bar. I employ for this purposea spring, M, provided with a slot, 8, by which it can be clamped and held by the thumb -screw f. The end 25 of this spring rests on the point of the presscr-foot, so that it will rise and fall with the presser-foot to allow the cloth to be fed along, and the spring is provided below the end twith a bearingend, 1;, that bears on top of the cloth and holds it down at the point opposite the needle, so that it cannot rise above the edge of the gage-bar B. If desired,a shorter ire-enforcing spring, N, may be used resting on top of the spring M.

Vhat I claim as new is In a tucking attachment for sewing-machines, the combination of the plate A, provided with a guide-flange, a, resting outside of theneedle, a gage-bar, B, attached to the plate resting inside of the needle, an attaching-bar, 0, provided with a series of holes to attach the device to asewing-machinebed by a HAYMAN FREEDMAN.
