MACl-HNE FOR MAKING STITCHED TRIMMINGS AND MOLDINGS.

SPECIFICATION forming part of Letters Patent No. 279,257, dated June 1?; 1883, I I Application filed Marel119, 1883. (N0 model.)

To all whom it may concern Be it known that I, CHARLES KNocn, of the city, county, and State of New York, have invented certain new and useful Improvements in Machines for Making Stitched Trimmings and Moldings, of which the following is a specification.

This invention has reference to an improved machine for making stitched trimmings and moldings for ornamenting cofiins, for millinery, and ladies dresses, the machine being adapted to shape and stitch the trimming, so that large quantities of the same can be turned out. i l

The invention consists, essentially, of a machine for making stitched trimmings or moldings, composed of an organized double sewing mechanism the double presser-foot of which works in connection-with a verticallya-ecipro eating V-shaped former and with a reciprocating and vertically-oscillating pusher of triangular shape, the pusher having a raised central nose and sharp recessed edges, by which latter the material to be plaited and stitched is pushed forward toward the double sewing mechanism.

The invention consists, further, of certain details of construction of the operating parts and of actuating mechanisms by which motion is imparted to the same from a common driving-shaft, as will be described more fully hereinafter, and finally be pointed out in the claims. In the accompanying drawings, Figure 1 represents a front elevation of my improved machine for making stitched trimmings and moldings. Fig. 2 is a plan of the same, partly in horizontal section on line a: m, Fig. 1. Fig. 3 is a vertical transverse section on line y y, Fig.

2. Figs. 4 and 5 are detail perspective views, respectively, of the pusher and former. Figs.

6 and 7 are respectively a top view and a vertical transverse section on line a z of a trimming or molding made on my improved machine. Figs. 8,9, and 10 are respectively top viewsand side Views of the pusher and former,

showing them in different positions for shap-' ing the trimming; and Fig. 11 is a detail side view of the mechanisms for actuating the pusher.

of reference indicate corre 5o suitable distance from each other, a presserbar, B, with a double presser-foot, B, said double presser-foot being provided with slots I b I) for, the passage of the needles, each foot or wing of the same being bent in upward direction and inclined sidewisc, as shown in Figs. 2 and 3. The inclined wings of the presserfoot B are made beveled from their thicker upper ends to their sharp lower edges. The needle-plate (l is slotted below the double presse'r-foot B for the double feed, and for two rotating hooks of the usual construction, (not shown in the dra\\'ings,) one for each needle, which hooks are not placed on the same shaft, but on two separate shafts, to which, by an auxiliary shaft and suitable gear-wheels, mo tion. in the same direction is imparted. The double sewing mechanism thus described is provided with the usual accessories such as spool -holdcrs, tension devices, and threadguidesand is actuated from a drivingshait, E, that receives motion bya belt-andpullcy transmission from a treadlc or power-shall, as the case may be.

All the parts so far described, except the peculiarly-constructed double presser-foot, are old and well known, and I do not make any 85 claim for the same.

In front of the double presser-foot B is arranged, in converging slots ffof the needleplate G, a vertically-reciprocating V-shaped former, F, that is composed of two separate wings, f f, which are inclined at a suitable oblique angle to the longitudinal center line of the sewing mechanism. The upper edges of both wings of the former F are beveled, so as to take a better held of the fabric to be plaited 9 5' and stitched on the machine. The former F receives intermittent vertical]y-reciprocat1ng motion from the driving-shaft in the following shaft, F turning in suitable bearings below the needle-plate O. A curved arm, F, at the opposite end of the shaft F is raised or lowered by means of a cam, F*, keyed to a short auxiliary shaft, F", which latter receives continuous rotary motion by gear-wheels f f" from the driving-shaft E. The shaft F turns in bearings of the supporting-frame of the machine, and is located back of the driving shaft,

as shown in Fig. 2. The same auxiliary shaft serves also for imparting motion to the reciprocating pusher (l, which is arranged in line with the longitudinal central axis of the former F and double sewing mechanism.

The shank G of the pusher G is loosely applied to a sleeve, at the end of. a lateral arm, G", so that the pusher (J: is capable of some-laterallyoscillating motion, owing to the axial turning of the shankG in the sleeve 9, whereby it retains always a horizontal position. The lateral arm G" is secured to a shaft, G, that slides in bearings G" of the plate 0, parallel to the central axis of the sewing mechanism, and is intermittently reciprocatml by means of an anti-friction roller, applied to the gear-wheel f on the shaft Fflwhich anti.friction roller-engages at every revolution of the gear-wheel f a fixed downwardly-extending arm, G on the sliding shaft G. A spiral spring, g", that is applied to the sliding shaft G and the plate (1, keeps the fixed arm G" in contact with the anti-friction roller g of the gear-wheelf". The gear-wheel f is further provided with a raised sidewise-projecting .rib, 9, that extendsaround the greater part of the gear-wheelj". The lower end of the arm G is pressed against the rib g by a spring, g", as soon as the roller releases the arm G". The raised rib serves to turn the shaft G axially in its bearings, and to impart thereby an upward motion to the pusher G. \Vhen the arm G passes along the short smooth space between the ends of the rib 9 (shown in Fig. 11) the pusher is lowered. At the same time the pusher G is carried forward by the action of the roller g on the arm G of shaft G".

The pusher G is made with V-shaped knife 71, the point of which is in line with the direction in which the fabric moves under the ncedles. The knife h is provided with a central raised and curved nose, 71. The edges of the knife h are provided with notches 713-, sons to form sharp serrations, that take hold of the fabric and push the same forward against the double presser-foot B, so as to expose it to the action of the former F and the double sewing mechanism described.

In place of the mechanism described for act uating the vertically-reciprocating former and the oscillating and longitudinally-reciprocating pusher, any other equivalent mechamism by which the same operation of parts is accomplished may be employed, as I-do not 'desire to confine myself to the special mechanism shown.

both sides.

By the joint operation of the devices described, a stitched trimming or melding of about the character shown in Figs. 6 and 7 is obtained.

The operation of the machine to produce the trimming or molding is as follows: The piece of fabric-is folded at the edges by a folder of the :usual construction.

It is thenmoved by the pusher G against th e raised former F, and thereby puffed up. This operation is shown in Fig. 8. The former F next descends beneath the cl oth-plate, so as be out of the way of the pusher G, which is then moved forward. The forward motion of the pusher carries the puffed fabric forward against the wings of the presser-foot, the nose of the pusher proj ecting between the wings, as shown in Fig. 9, so as to shape thereby the puffed fabric laterally. The needles now-descend and stitch the so plaitcd fabric at The pusher G is next raised and returned to its rearmost position, as shown in Fig. -l(),at which moment the former F is raised again, so as to puff up the fabric and expose the required fullness of fabric to the action of the descending pusher, which pushes it forward again into the recess between the wings of the presser-foot, so as to plait the same and expose it simultaneously to the action of the needles, as before. The feed carries then the soformed trimming forward, while a new section of the fabric is exposed by the joint action of the former and pusher to the sewing mechanism, which fOllllSfllGlGbY a stitched trimming or molding with puffed plaits and of a highlyornamental appearance.

I reserve the right to tile a separate appli cation for Letters Patent on the trimming or molding shown in Figs. 6 and 7, as the same forms anessential part of my invention.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination of an organized double sewing mechanism provided with a double presser-foot having upwardly-bent and laterally-inclined wings, a vertically-reciprocating V-shaped former guided in slots of the nee dle-plate, and a reciprocating and verticallyoscillating pusher, and mechanism for actuating the parts from a common driving-shaft, substantially as and for the purpose set forth.

2. The combinationof an organized double sewing mechanism the double presser-foot of which has upwardly-bent and laterally-in.- clined wings, a V-shaped former, mechanism for reciprocating the same, a V-shaped pusher, and mechanism for longitudinally reciprocatingand vertically oscillating the same, the former and pusher working conj ointly with the pressei ibotand double-sewing mechanisms to plait and stitch the fabric, substantially as specified.
