TUCK-M ARKER FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 268,013, dated November 23, 1882- Application filed June 19, 1882. (No model.)

To all whom it may concern:

Be it known that I, HARRY O. GOODRICH, residing at Chicago, in the county of Cook and State of Illinois, and a citizen of the United States, have invented new and useful Improvements in Tuck-Markers for Sewing-Machines, of which the following is a full de- 7 ing a section through the notch device or creaser and its support; Fig. 6, a detail, being ,a transverse section of the notch device or creaser in a disk form; Fig. 7 a detail, being an edge view of the disk notch or creaser; Figs. 8 and 9, details, being a'face view and an edge View, respectively, showing a modification in the form of the notch or creaser;

Tuck-markers of the class known as notch and blade, as now constructed, have the notch or crease which coacts with the blade to produce the mark for the tuck of 'a uniform depth, and in use ithas been found that in creasing or tucking material of different thicknesses the operation of the creasing devices is not perfect, for the reason that the notch, being of a uniform depth, in tucking thin material, the material is liable to be drawn or puckered, while in tucking thick material the crease or mark is liable to be faint and indistinct, it being impossible to have a notch of one depth work perfectly with both thin and thick niaterial. With the present form of construction of tuck-markers of this class it is impossible a notch or creaseto suit the thickness of the material; and its nature consists in providing a creaser having a groove or recess of varying depth and adapted to be turned or adjusted to bring a shallow, medium,'or deep portion into action, as may be required, for thin, medium, or thick material, as hereinafter described, and in adjusting the notch-arm to have the notch and blade coincide.

In the drawings, A represents a base-plate made of sheet-brass or other suitable material, having on one end a turned-up flange, a, and an upwardly-turned lip or projection, a, with' an opening between them. This plate, as shown, has a portion cut away where attached to the bed-plate of themacliine,-leaving a body or main portion of sufficient width to receive the other plates or parts of the marker; but such plate A may be of the form of construction shown, or of some other well-known form.

B is the clamp-plate,for attaching the blade and creaser-arms to the base-plate, andhaving a recess, 1), for the passage of a thumbscrew by which the tucker is attached to the bed-plate ofthe machine, the slot or recess b permitting the necessary end movement to ad-' just the notch and blade for the width of tuck, as usual.

0 is a thumb-screw for clamping and holding the notch and blade arms, the shank of the screw passing through a slot, 7), in the extension B of the plate B, and entering the base-plate A, and, as shown, the clamp-plate is maintained in the same relative position to the base-plate A by an upwardly-projecting lip, c, on the base-plate, which passes through a hole, 0, in the clamp-plate B.

D is the main arm or portion of the notchoarrying plate. This arm or portion 1) is pro vided with a longitudinal slot, d, through which the shank of the thumbscrew 0 passes, and by which the necessary end movement is provided for adjustment of the width.

E is the extension or arm carrying the edge or blade 6, and provided with, a lip or, projection, 0, under which the material passes. This arm or extensiouE and the arm 1) are made from a single piece of sheet-brass or other too rear end to the'rear end of the arm or plate D,

and having its front end left free.

G is an arm or extension of the plate F, on the upper face of which the vibrating arm strikes to cause the creaser to act and producethemark. Thecreasingdeviceismounted on this arm or extension G in line with the blade 6. This creasing device, as shown in Figs. 1, 2, 3, 5, and 6, is a disk of a circular form, having its periphery or edge grooved or notched entirely around, the groove or notch varying in depth, as shown in Figs. 5 and 6. This construction, it will be seen, produces a notch or recess varying in depth, so that by 'turnin g the disk, a depth of notch or recess to coact properly with the blade for the thickness of material can be brought into position for use.-

As shown, the diskf'is attached to one'end of a shank or pintle, g, which may be of a round form, as shown in Figs. 5 and 6, when used with a disk notch or creaser f, so as to allow the creaser to be turned. This pintle or shank passes through a support or box, It, attached in any suitable manner to the upper face of the arm or extension G, and,as-shown, the end 'opposite to the creaser f is screwthreadcd, and receives a nut, i, by means of which the creaser is held in position, and at the same time the attachment is such as to permit of the ready adjustment of the creaser as required for use, as all that is necessary to be done is to loosen the nut 2', turn the creaser to the desired position, and then screw down the nut,drawing the face of the diskf against the face of the support It with sufficient force to prevent turning.

Instead of leaving a complete disk, as shown in Fig. 6, portions of the disk might be removed,as shown in Figs.8 and 9,leaving arms or projections, each having a notch or recess therein, each varying in depth, so that by turning the creaser any desired one of the arms or projections could be brought into position to co-act with the blade, and instead ofa jamnut, i, being used to retain the creaser in position a set-screw, i, passing through the support or box h, and having its end coming in contact with the pintle or shank g, could be used for fastening the creaser in position, such form of construction being shown in Fig. 4.

His an arm or plate attached to the rear end of the arm or plate F; I, the spring for returning the vibrating arm or lever; J, the vibrating arm or lever, connected by the hook it with the needle, so as to be carried down by the descent of the needle-bar, as usual. These parts H I J may be made of a single piece of material, as shown, or in any other suitable and well-known manner.

, In putting the parts together, it oftentimes happens that the extensions or arms E and G do not properly coincide so as to bring the blade and notch in line, and the action of the two will therefore not be perfect. To remedy this defect, Iprovide a raised portion, j, in the arm or plate F, by means of which the notch and bladecan be brought exactly in line, the necessary adjustment being made by opening or closing the bend j, as required, to lengthen or shorten the arm or plate to bring the notch and blade in line, the opening of the bend or raisejincreasing and the closing of such bend decreasing the length of the arm.

The operation of the creaser is as follows: If the marker is to be used with fine material, the creaser is turned or adjusted to bring the shallow notch or portion of the groove in position to coact with the blade, so that as the vibrating arm descends the notch and blade will produce the mark on the material which is placed between them, as usual. If medium material is to be operated upon, the creaser is turned to bring the medium depth of notch or A groove into position to coact with the blade, and

if coarse or heavy material is to be operated upon the creaser is turned to bring the deep portion of the notch or groove in position to coact with the blade. This arrangement enables the same tuck-marker to be used in operating on fine, medium, or heavy material, as all that is necessary to be done is to turn the creaser to bring the required depth of notch into position for use. The adjustment for width of tuck is made by moving the creasing devices toward, or from the end of the plate A, as usual. In adjusting the notch and blade to bring them in line, in case they do not exactly coincide, the operator, if the notch is too far out, by taking a pair of piuchers can bring the bend j closer, so as to cause the notch and blade to coincide, or, in case the notch is too farin, can spread the bend apart, so as to bring the notch and blade in line.

Instead of using a box or support, h, extending across the arm G, ears might be used, one on each side, for supporting the pintle g, or the pintle might be supported in some other.

. suitable manner; and instead of using a round pintle, g, a square shank might be used, such shank permitting of four adjustments.

This creasing device could be applied to tuck-markers now in use by providing ears or other support on the notch-arm to receive and support the shank or pintle of the creaser.

If desired, only three adjustments, to produce the three depths of notches ordinarily required, could be provided,in which case three arms or acting points need only be provided.

Instead of extending the groove entirely around the periphery of the disk, as shown in Figs. 6 and 7, it is evident that notches of different depths could be made on four sides, producing a form of device essentially the sameas that shown in Figs. 8 and 9 with the disk entire.

In case the creaser becomes dull or inoperative from any cause, it can be removed and a vice ,which is operated bya vibrating arm and constructed at its forward portion with the bend j, which is capable of being opened or closed to lengthen or shorten the plate, and 15 thereby adjust the creasing devices in proper line, substantially as described.
