Letters Patent No. 110,670, dated January 3, 1871.

IMPROVEMENT. l N TUCKING DEVICES FOR SEWING-MACHINES.

The Schedule referred to in these Letters Iatent and making part of the same.

To all whom it may con-cam:

Be it known that I, Aanox Mounnousn, of Hartford, in the county of Hartford and State of Connecticut, have invented a new and useful improved lueker or llaiter for Sewing-Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing making a part of this specification and to the letters of reference marked thereon, in which Figure l'is a plan view of my invention;

Figure 2 is a reverse plan view of the same;

Figure 3 is an end view;

Figure 4 is an opposite end view;

Figure 5 is a side view;

Figure 6 is a side view of that part of the device which regulates the distance between the tucks or plaits;

Figure 7 is a side view of the gun the width of the tacks or plait's;

Figure 8 is a side view of the spring guide which is attached to the main bar;

Figure 9 is a plan view of the spring gauge before it is bent or doubled; and

Figure 10 is a plan view of the larger outside gauge before itis bent.

My invention relates to a device to be attached to the presser-foot or presser-bar of a sewing-machine, for folding the cloth while it is being sewed in making tucks or plaits, and is an improvement upon the device for which Letters Patent were granted to Aaron ge which regulates Morchousc and Alfred It. Heath, August 4, 1868,

No. 80,653; and

It consists of a short bar of metal, having upon its lower side a guide-swell similar to that shown in the device for which said Letters Patent were granted; and to this bar is attached a spring guide to press the lower parts of the tuck together, .to insure the passage of the needle through the entire lower edge of the fold.

The bar has also another piece attached to the under side, which may be termed the presser-guide, and is designed to give direction to the cloth in pressing it over to one side to form the fold.

The bar has a slotted gauge attached thereto, having a turned down or guiding-edge, and-which is made adjustable upon the bar by means of a small thumbscrew passing through the slot into a threaded hole in the bar; and to the said bar is also attached a slotted gauge, one part of which is bent nearly together, and the end of each bent part is elongated in a direction at nearly right angles to the slotted part of the gauge, and parallel to the direction of the movement of the cloth through the machine and the ilmcr edge of the upper elongated part is bent down in nearly a vertical direction just inside the inner edge of the lower elongated part.

That others skilled in the art may be able to make and use my invention, I will proceed to describe its construction and the mode of its operation.

In the drawing 0 represents the main bar, which, as represented; is particularly adapted to the Wheeler 8: Wilson machine, in which a glass presser-foot is used, although it may be arranged to be adapted to any of the machines in market by changing the outer end of the main bar to suit the construction of the presscr-foot of any particular machine, and according as the'work passes under the needle in different machines, whether in one direction or another, the device may be made as shown in the drawing, or it may be reversed in its arrangement and all its parts placed upon the opposite side of the needle-hole B.

'Lhegnide-swell is shown at O, and is precisely similar to and serves the same purpose as that shown in Letters Patent granted to Aaron Morehouse and Alfred 16. Heath September 7, 1869, No. 94,628.

The spring guide is shown at J, and is the termination of the piece "t which is attached to the bar 0, and extends out to one side at about a right angle to the said bar,,and is then bent or doubled and extends back to a point underneath the said bar.

At its termination it is widened or extended out into the point e, and this point may be somewhat curved backward so as to leave a little more space between this part of, the spring guide J and the Presser-guide, which is shown at D, and which is attached by soldering or other, convenient method to the bar 0.

This presscr-guide may be curved near the end, as shown at a, as this form facilitates the passage of the cloth into the space between the guide-swell O and the spring-guide J, and uiulerneath-the bar G.

The curved part of this presser-gnidc, at the end a, presses down-upon the cloth passing underneath it suiticicntly hard to prevent the edge which is folded from moving or working to one side, the edge of such folded part passing along upon the cloth-plate and against the edge of the curved part a, although there is one thickness oi cloth between said part a and the edge of the fold.

The gauge 11, having alongitudinal slot therein, and a turned-down edge, 0, thereon, is attached to the bar 0 by means of a small thumb-screw inserted through the slot and into a threaded hole in the bar 0, and the bar may be recessed at s to receive the gauge and secure it more firmly in place.

The piece (I, having the armsf and It, is attached to the piece t'by means of a thumb-screw passing through a longitudinal slot in the piece (Z andentering a threaded hole at n.

' 'lhe arinh is bent or doubled underneath the arm f, and upon the extremity of this arm f is an elonguide J, or said back part may be widened to accom-' plish the same result. 7 j I The arm 7:, which is bent undemeath the arm f, has an elongated part or projection, h, thereon, extending horizontally at nearly right angles to the-arm 71, the projection g being just over and its turneddown edge a little inside the projection 7:.

The awn 7:- may be somewhat wider than the 'arm f, and its outer edge :0 may be turned upward a little to permit the cloth to pass freely under the said arm h.

A small piece, 2:, may be attached to the piece 1', which piece a; being raised somewhat enters the longitudinal slot in the piece (I, and prevents any. side or swaying movement of the gauge or pieced.

A small point or projection, 0', may be formed upon the guage b, which point may be turned upward slightly that the cloth may pass freely through said gauge 1), although this is not necessary for the successful operation of the gauge.

The operation of the device is as follows:

The device is attached to the presser-ioot or presserbar of the machine, and the cloth is gathered somewhat loosely and passed into the slot tbetween the presser-guide D and the spring-guide J, and as the cloth passes in it is folded together, and aided by the presser-guide D and the side of the bar 0, shown in.

dotted lines in figs. l and 2, the fold is turned over into a horizontal position and passes underneath and against the tin'ned-down edge of the guide b.

The spring guide .1 keeps the lower part of the fold up against the guidc-sw'cll 0, so that the needle passes through the lower part of both sides of the fold.

The fold which has been previously sewed is passed in between the arms f and h and their projections g and h, the latter pressing the fold up against the turned-down edge of the part 1 shown at g, which turned-down edge also presses down against the lower edge of the fold which is passing between the two arms f and h.

It will be perceived that the cloth or the main body the same, nor-any part thereof, irrespective of my construction and arrangement of the same; but hav ng described my invention,

\Vhat I do claim as new, and desire. to secure by Letters Patent, is-- 1. The presser-guide D, when attached to and used in connection with the main bar G, having the guideswell O thereon, and having the spring guide J attached thereto, substantially as herein described.

2. The same in connection with the adjustable gauge I), constructed and operating substantially as specified.

3. The combination of the main bar 0, presserguide I), spring guide J, gauge b, and gauge (1, all constructed and operating substantially as set forth.

4.. The adjustable gauge 11, having the armsf and h thereon, and formed so that the sewed tuck or plait may pass between and in contact with said arms, and be guided in itspassage by the edge g, while the main body of cloth passes underneath both said arms and upon the cloth-plate of the machine, substantially as described.

5. Devices substantially as described, and attached wholly to the presser-foot or presser-bar, whereby the fold in the fabric is gauged or measured, folded, and sewed simultaneously, and the cloth plate is left enth'ely free, substantially as set forth.

AARON MOREHOUSE.
