'IMPROVEMET IN TUCK-CREASING- ATTACHMENT FOR SBWING-IVIACHINES.

The Schedule referred to in these lLetters Patent and making part of the same I, Hanny C. GooDmoH, ofthe city ot' Chicago, in the collnty ofOook and State of Illinois, have invented certain new and useful Improvements in Tuek-Marli ers for Sewing-lvlaehiues, of which the following is a inll description, reference being had to the aceompanying drawing making part ofthis specification, in

Figure 1 is an elevation.

The drawings are full size. i My invention relates to that class ot' tuck-markers in which the mark or crease in the cloth is made by means of a wheel rotating over a blade, the clot-h passing between the wheel and blade.

'lhe principal object of my invention is'to construct a tuck-marker, so that that part of the cloth which is in line with thevcreasing-wheel and blade will, while being creased, be carried forward by the act-ion of the tnekgmarkeras fast as that part of the cloth which is being stitched is` carried forward by the feed ofthe Y sewing-machine. I accomplish this by means of two wheels arranged upon the same shaft, and revolving therewith, one operating as a creasing-wheel, the

' other as a driving-wheel to operate the creasing-wheel,

both wheels so arranged as to be in constant contact with the cloth while in use, the driving-wheel located iu the line ofuthe stitching outside of aud in front of the presserfoot, and being so serrated or toothed that the `moving-cloth catching upon the points or teeth on the periphery of the wheel will rotate the same, while the creasingwheelis so serrated that its teeth catch in the cloth, carrying it forward.

Auotherobjeetof my invention is to enable the operator'to adjust at pleasure the pressure of either or of both'of the wheels upon the cloth; thisI accomplish bythe mea-ns hereinafter described.

A represents a. metallic plate, which may be made of sheet metal,v in which is a slot, s, through which a thumb-screw passes for the purpose of securing the devieeto thesewing-machine, in the usual manner.

y D is a movable gauge, arranged and used in thc ordinary manuel'. i

B B'iar'e two standards, permanently fastened to A, thelatter bcing;r a little longer than the former. 'lhey areplaced alittle distance apart, may be made ot a single piece ot' sheet metal, bent iu proper shape, au openingbeing provided at 'o through which to pass the bar f.

The" piec`e`or frame C d b is made from a single piece ,of metabub being arms extending from C, in which arms are bearings, iu which the shaft D revolves.

E is a serrated wheel loeatedupon the shaft d; this wheel and shaft are so constructed that the wheel cau be moved laterally upon the shaft, but cannot rotate thereon, mit, only with it. This is accomplished by well-knowimethods, one of which is shown in fig. 3. This wheel must be so made as not to be moved too easily on the shaft, and so that it will remain where placed.

F is another serrated wheel, also havinga groove in its face extending around the entire wheel. A This wheel is permanently secured to the shaft ll near the outer end thereof. Beneath the groove in F isa. projection or blade, e, attached to A, which blade, with the' grooved wheel F, makes the mark in the cloth.

Y, The teeth upon these two wheels are near each other, presenting sharp points to the cloth, and the teeth in these two wheels do not project therefrom in the same direction. angle and iu such direction that the cloth, as it is drawn along under it by the feed of the machine, will catch against the points of the teeth and cause the wheel and shaft to rotate, 4(see liff. 3,) while the teeth upon F project therefrom in such a direction that, as it revolves, the points of the teeth Catch in the cloth, forcing it forward. The wheel E may be grooved as well as serrated, as shown in figs. l and 2.

It' necessary, the wheel F maybe made a little larger than E, thus making allowance for friction, and rendering it certain that thecloth in the line 0t`- the marking-wheel will move as rapidly as that partiu the `line of stitching.

U is pivoted at 4its inner end to the bare, which is also pivoted between the two standards i, giving the desired iiexibility to the working parts, and enabling nie readily to adjust the pressure of either, or of both wheels, upon theI cloth, which I-do as follows:

In U is a long longitudinal slot, h. A. long bar,f, passes between the two standards, and is there snpported in any suitable manner, as shown. It extends through the metal forming the standard, and requires no other support at that point. The inner end is bent in an L-forni, the extremo end passing into the slot- If.

'iu (I.

A lever, h, is pivoted to 15'; the lower arm of the lever is cani-shaped, and cornes in Contact with the The teeth upon E are at suoli an end nearer one wheel than the other, the pressure on the sercral wheels will be unequal, but can still be regulated as before.

A cloth-smoother, g, may be used with this device. A

In operation, the device is attached to the sewingmachine so that the wheel E will be in front of the feed, and in the line of the stitching, the parts being adjusted with reference to the width of the tuck to be made.

The cloth is passed under both wheels. As the cloth is drawn along by the feed of the sewing-inaehine, if the pressure ot' the wheels upon the cloth has been properly regulated7 the cloth will catch upon the teeth in the wheeh, causing it to revolve, also revolving the shaft d and creasing-wheel F; at the same time the teeth in F will catch in the cloth beneath it, and carry it along between the blade and groove in the wheel, making the mark i'or the next tuck, the cloth in the line of stitching, and that in l line with the creasing-wheel, being carried forward sin multaneously and with equal speed, and thus the cloth will he kept smooth, and a mark will be made by the creasing-wheel, parallel to the stitching.

' The end of the bar f, in the slot k, should usually be midway between the two wheels. v

The bar f is not entirely rigid, but yields enough to permit seams in the cloth to pass beneath the wheels.

The frame C is somewhat seliladjusting, being pivoted to c, and the latter to the standards, as before described.

Having thus fully described my invention,

ters Patent, is as follows:

1. 'lhe combination of the plate A, wheels E F, shaft d, and frame C a b, constructed substantially as and for the purposes specified.

2. The movable wheel E, located outside of the presser-foot oi' a sewing-machine, in combination with the shaft d and creasing-wheel Is, substantially as and for the purposes specified..

3. The combination ot' the hinged bar c, frame C, wheels E and F, and yielding bar f, with the plate 'A and guide D consti-noted and operating substantially as specified.
