SPECIFICATION forming part of Letters Patent No. 448,695, dated March 24, 1891. Application filed July 26, 1887. Serial No. 245,394. (Model.)

.To all whom t may concern:

Beitknown that I, EDWIN J.'l`OOF,a citizen of the United States, and a resident of New Haven, State of Connecticut, have invented a new and useful Improvement in Tuck-Markers, of which the following, taken in connection with the drawings furnished, is a specification. i

My invention relates to tuck-markers; and it consists more particularly in the construetion and combination of the several parts forming the attachment whereby the marking apparatus and edge-guide, both forming part of the attachment, may be adj usted independently or together by means of a single adjusting device, and also in the construction of the supporting-frame in a manner to serve as a covering for the arms or Shanks which support the several guides, marking devices, dzc., the object of my inventionbeing to simplify and condense into the most practical form the parts requisite in vsuch attachments to obtain the necessary adjustments, and also protect the adjustable features thereof by covering and strengthening the frame very materially without increasing the weight in metal employed.

Referring to the drawings, Figure l represents a top view of my improved tuck-markin g attachment, and Fig. 2 represents the bottom. Fig. 3 represents the side of the attachment from which the marking devices and actuating-lever project. Fig. 4c represents an end view of the attachment. Fig. 5 represents a top and end view, respectively, of the sliding edge-gage.. Fig. 6 is a top view of the bent arm which supports the marking devices. l

In the drawings, A represents that part of the frame of the attachment of a partial or semi-tubular form.

B represents an opening in that part of the f rame which serves to connect with the clothplate of a sewing-machine.

C is a rod forming the slide part of the edge-gage I).

E is that part of the crook-arm which supports the creasing device which is hinged thereto, and F is the lower` part of the arm supporting the creasing-edge G, upon which the notch-point or marking-arm indicated at l-T operates.

I is a rock-shaft pivoted to the upper side or top of the tubular part of the frame before referred to, the rock-shaft in its motion bearing upon the top or hinged back of the marking-arm I-I when actuated through the medium of the arm J by contact with the reciprocating needle-bar of the sewing-machine.

K is a flexible smoother extending through an openin g in the edge-gage D, before referred to. (More clearly shown in Fig. l of the drawings.)

L is the screw and nut for clamping the adjustable parts of the tucker in a desired position, the screw being of a tapered or wedgeshaped form,largest at its lower point, or that opposite the end provided with a nut.

The edge-gage D is provided with a gooseneck and point, (see Fig. 5,) represented at C in the drawings, adapted to indicate in connection with graduations. (Shown in Fig. l of the drawings.)

The marking devices and the ed ge-gage are moved along longitudinally, as required in practice, to the desired position. The thumb nut or screw is then tightened, by which the shanks of the movable parts are pressed outwardly against the inner sides of the tubular part of the frame, where they are rnily held locked in position, which adds additional strength to the frame part of the attachment.

Having thus set forth my invention, what I claim as new, and desire to secure by Letters Patent of the United States of America, 1s-

l. In a tuck-marker, the combination, with an attaching-plate and a semi-tubular extension serving as a supporting-frame, a rocking bar secured above said semi-tubular eXtension, and an upper marking device adapted to be operated by the contact therewith ot the said rocking bar, of an edge-guide and a marking-point, each provided with a supportingshank and a screw for acting on said supporting-Shanks, provided with a wedge-shaped head and an adj Listing-nut, substantially as and for the purpose set forth.

2. lAtuck-marking attachment consisting of an attaching-plate provided with a semitubular extension serving as a supportingframe, guide, and cover for the adjustabe parts of the attachment, an edge-guide IOO tached to a sliding` rod, lhox lutter being provided with :in iluliezLLing-poinl, arranged substantially as Set lorlh, 2L markingr device, and an adjusting-screw provided with ai wedge- Shaped head and u nut and adapted to adjustahly hold said edge-guide and said innrking` device by compressing lhe shank paris of each of the saine against ille inner Wall of said semi-tubular extension, substantially ns described, and for the purpose set forth.

A tuck-1narker consisting of the following` parts in combination: an atizlchillg-plzlte i with a semilubnlzir extension eerving` :is n K supporLing-frzinie, 21. gage, und 2L marking dcvice, each provided with L Supporting rod or shank located and adapted to operate and slide in said Semi-tubular extension, fr screw for acting` on said rods or shrinks, provided with L wedge-shaped head and an adjustingnut, and i smoothing device, Substantiallyas described, and for the purpose set forth.
