IMPROVEMENT IN -MARKERS.

Specification forming part of Letters Patent No. 162,225, dated April 20, 1875; application filed December 8, 1874.

CASE A.

T 0 all whom it may concern Be it known that I, HARRY G. GOODRICH, ot the city of Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Tuck-Markers, of which the following is a full description, reference being had to the accompanying drawings, of which there are two sheets, and in which Figure l is a side elevation, showing my device attached to a Willcox and Gibbs sewingmachine, such parts only of the machine being represented as are necessary. Fig. 2 is a top view of the device detached from the machine; Fig. 3, a section on line as of Fig. 2; Fig. 4, an end view of the parts shown. The drawings are full size. Figs. 5 and 6, sheet 2, represent variations in form.

In the drawings, A represents the clothplate of a sewing-machine; B the rocking arm which operates the needlebar, and which is pivoted at C, and operated or driven at I). a is the main plate of my device. It is secured to the cloth-plate by a set-screw, b. It may have lugs or projections c at the outer end, to come in contact with the edge of the plate A, to aid in keeping it, a, in place. at is a longitudinal recess in the under side of a to receive the sliding plated, but it is not as deep as the thickness of d, so that when Ais secured to A 61 will be held fast, but it can be adjusted by first loosening the screw 1). The end of this plate (1 near the needle is provided with a lip, 02, under which the last completed tuck passes, anda blade, 19, which serves as one of the markers. 7' is a rod or lever, the outer end of which is connected to the end of the needle-arm by means of a rod or hook, s. This lever 1' is pivoted to the ears or bearings 6 upon the main plate so as to have an oscillating movement. The inner end of r is hollow, and receives the adjustable rod f, which is held in position by the set-screws g. h is a grooved disk, permanently secured eccentrically to the rod f. This disk is the upper marker, and by turning the rod f the pressure upon the cloth can be adjusted. In-

stead of the disk 2. many-sided block may be used, the edge of each side being grooved, or

a marker vertically adjustable may be secured to the end off by means of a set-screw. dis a spring under 1". Its office is to carry the upper marker 71. away from the cloth at the proper time. This could be done by the positive action of 8, if secured to B in a suitable manner to do that work. 70 is a gage secured to a by a screw, Z.

In use, the plate 61, which carries the under marker, is to be located with reference to the desired width of tuck, and secured in position by means of the main plate and set-screw b. The upper marker is then brought to the proper position to engage with the under marker, and is secured in place by means of the setscrew 9. Then, when the needle descends, the outer end of the rod 1 will be raised by means of the outer end of the needle-arm B. and connecting-hook s, which will force the marker it down upon the cloth, and when the needle rises the marker It will also rise, permitting the cloth to pass freely.

It is obvious that the spring t' might be extended and provided with a notch to engage with the blade p, and so arranged as to be operated by the disk h, in which case the disk need not be grooved on its edge, andin which case it will be desirable to connect the outer end of t' permanently to the outer end of d, so that the upper and lower markers will be adjustable together.

If the arm B were extended down at its outer end, so as to come on a line with the rod or bar 1", such rod 1" could be connected directly with the arm B, instead of through the link or rod 8. Such connection can also be directly made with the arm constructed as shown in Fig. l, by turning up the end .of r and engaging it directly with the arm, which can be done by inserting a pin, 1., on the arm B, over which to pass the end of r, as shown in Fig. 5, sheet 2. By slotting the end of the rod, and so arranging the parts that the pin will be in the slot, the inner end of T will be thrown up by the action of B, instead of by the spring 6. The end 1) of the rod 1" can, in some machines, be made to engage with the needle-arm, forward of its pivotal point, instead of back of such point. This will be desirable in machines of the Wheeler and Wilson class. The manner of doing this is represented in Fig. 6, in which to is a pin in the needle-arm, and the up-turned end Q7 of 1" engages with this pin in such manner that as the needle descends U will be forced up and the opposite end will be carried down. In this figure the upper marker is carried by the spring 2, and the pressure on the cloth can be adjusted by the screw in the end of the movable part f. There are machines in which the outer end of the needle-arm extends below the line of the cloth-plate, and the rod 1' can, in such machines, be connected with the lower end of the needle'arnn extended as stated.

In this device, and in all the variations described, the rod or bar 1 is pivoted as near its center as convenient, to the main plate, and the markers are adjustable without regard to the main plate and rod 1', the position of which remains unchanged.

What I claim as new, and desire to secure by Letters Patent, is as follows 1. The pivoted bar 1', in combination with the plate a, and the rear link or rod connected directly with the bar and forming an extension thereof, substantially as and for the purpose specified.

2. The combination, in a sewing-machine tuck-marker, operated by a non-flexible bar, if the separately-adjustable grooved disk or plate h, and the blade for adjusting the length of the stroke between the two, substantially as described.
