Speccaton of Letters Patent.

Patented Feb. 18, 1908.

Application filed March 16.l903. Serial No. 147.890.

To all whom it may concern:

Be it known that I, WILLIAM M. AMMER- MAN, a citizen of the United States, and resident of New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Ruffler Attachments for Sewing- Machines, of which the following is a specification.

This invention has for its object to provide an improved ruffler attachment for sewing.

machines that is simple in construction and efficient in operation the invention consisting in certain novel features of construction and combinations of parts as hereinafter set forth in detail and pointed out in the claims.

Referring to the accompanying drawings forming part of this specification, Figure 1 is a top plan view, partly in section, of a ruflier attachment embodying my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a similar view with the operating parts in a different position. Fig. 4 is a detail view illustrating a side and end view respectively, of one of the operating parts ofthe attache ment.

In the drawings, 1 indicates the main supporting plate or frame of the attachment which, as most clearly shown by dotted lines in Fig. 1, is provided with a notched or bifurcated arm 2 for detachable connection with the presser-bar of a sewing machine, upon which the attachment is adapted to be supported and held in operative position.

The ruffler-blade of the attachment, indicated at 3, is secured to a sliding carrier 4 which is pivotally connected at 5 with the lower end of a vertically-arranged lever 6,

-termed the ruiiler-blade lever, the upper end of which is pivotally mounted on a stud or pin 7 attached to the supporting-frame 1. This lever 6, in the operation of the attachment, is adapted to be oscillated to give the connected carrier 4 with the attached ruiilerblade 3 their usual horizontally reciprocating movement, the said carrier 4 being guided during its operation by an engaging pin 8 which projects from one side of the supporting frame 1 as shown.

The means for operating the lever 6 to impart an oscillating movement thereto comprises a lever 9, termed the operating lever, which is pivoted at one end upon the pivot 7 for the lever 6 and at its opposite or free end is bifurcated for connection with a projection on the needle-bar of a sewing machine from which it is adapted to be operated in the usual manner. This lever 9 is provided with two contact points for engaging with an intermediately located part of the lever 6 and operating the same, the said contact points being carried by the lever 9 at opposite sides of the pivot 7 and one, indicated at 10, being in the form of an arm or extension of the said lever, and the other, indicated at 11, being in the form of an adj usting-screw carried by a lug 11 on the said lever.

The lever 6, as a means for receiving the engagement of the contact points 10 and 11 of the operating lever, is rovided with an arm 12 extending outwardly at right angles thereto and into the path of movement of the contact point 10, t e upper end of which arm is bent at an angle, as at 14, and extends into the path of movement of the second contact point l1. By this arrangement and combination of parts, the operating lever on its up and down strokes causes the contact points 10 and l1 to alternately engage with the arm 12 of the lever 6 and oscillate the latter to communicate thedesired reci rocating movement to the connected ruffl blade, the length of the reciprocation of the latter being regulated by adjusting the p0si tion of the contact point 11 relative to the contact point 10 so as to vary the amount of lost motion between the same and the lever 6, it being understood that thethrow or movement of the operating lever is iiXed..

As the said operating lever moves in a at its upwardly-turned front end or toe 17,A

as 1n my former patent rNo. 629,786,dated July 25, 1899, is extended at such end and turned backwardly upon itself in the form of a loop, the front end of which is provided with a notch or opening 18, for the passage of the sewing machine needle in its vertical reciprocations. The principal purpose of thus giving a loopiform vto the toe of the presser-foot is to minimize the liability of the front end of the ruifler-blade being drawn upward by the work when the latter is being disengaged from the attachment and caught on the upper side of the presser, as was liable to occur with the presser as disclosed in my said prior patent. A further feature of the presser having a loop form at its toe as described is the fact that it prevents the presser becoming unduly bent or disarranged, as the upper side 19 of the loop extends backwardly upon Qr above a xed part of the attachment and so prevents undue downward movement or bending of the presser-toe, such backwardly extending upper side 19 of the loop being formed with an opening 20 therein asA an extension of the notch 18 through which the attaching-screw 21 for securing the'presser-foot to the attachment may be reached.

What I claim is:-

In a ruHer attachment for sewing machines, the combination, with the ruHerblade, of actuating means therefor7 comprising a ruffler-blade lever having an arm projecting laterally and upwardly therefrom with a space between it and the lever, and an operating lever located at the same side of the rufIier-blade lever as its said arm and being operative in a path intersecting the said space between the ruftler-blade lever and its arm and being provided with two contact points for engagement with the said ruHer-blade arm.

Signed at New York in the county of New York and State of' New York this 14th day of March A. D. 1903.

VILLIAM M. AMMERMAN.
