lMPROVEM-ENT IN TUCK-MARKERS FOR SEWING-MACHIN Specification forming part of Letters Patent No. 138,636, dated May 6, 1873 applicat'` February 4, 1873.

To all whom it may concern:

Beit known that I, HARRY G. Goonnron, of the city of Chica-go, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Tuck-Markers for Sewing-Machines, of which the following is a full description, reference being had to the accompanying drawing making a part of this specification, in which- Figure l is a plan view; Fig. 2, a side elevation; and Figs. 3, 4, and 5, details.

As tuck-markers have heretofore been constructed the pressure of the creasing devices varies as the width of the tuck varies-or, in other words, with the varying distance of the creasing devices from the needle.

The object of my invention is to so construct i an actuating -arm for a tuck-marker that the pressure upon the creasing devices will be uniform, although their position, relative to the needle,be changed; and this I accomplish by the use of a spring-arm to operate the creasing devices, wholly disconnected from the other parts of the tuck-marker, which arm is attached to a rigid bar or rod, which rod is adjustably connected with the lneedlearm.V

In the drawing, my inventionis represented as applied to a notch-andblade tuck-marker,

`adapted to be used with a Wheeler 8u Wilson machine, but it maybe used with other kinds of tuck-markers. y

A represents the bed-plate of the machine, and B the needle-arm. The presserfoot and other parts of the machine are not represented. C is the device used for securing the needle in place, and is constructed substantially as usual, except that the head is enlarged and provided with a hole and set-screw, 7c, to receive and hold in position the rodj. a represents a plate of sheet metal; b, a gage, adjusted relatively to each other by means of the set-screw d, and secured in place upon the machine by means of the thumb screw c, as

n filed usual. eis a spring-rod connecte to the plate a at g. The other end is bent, as epresented, and the extreme end provided y th a notch, which engages with a blade upoi between which blade and notch t y es, as usual. There is nothing these parts a b e of ,the tuck-mar My adjustable actuating-arm is a rod, f, sufficiently large to :l rigid, and a spring-arm, h, bent i shown, one end of which is per cured to the rod j', while the ot so formed as to come in contact y erate the spring rod or arm e. F I make this spring-arm h of stee In use, the plate a and the par therewith are secured to the bed machine in any desired position, the width of tuck to be made. the actuatingarm is then inserte in C, and its position so adjusted i i of the spring l1J will engage wit the spring rod or arm e, and, the secured in place by the set-screw is ready for use.`

As represented, the parts ar making a narrow tuck. If the y vices be moved to the right for t y making a wider tuck, the rod j" moved to the right and properly djusted, `as before; but this rod f being rigi its change of position will not sensibly att' ure of the spring h upon the crea What I claim as new is as foll The adjustable bow-like aetuat g-arm, consisting ot' the rigid section or a l ,f and the springarm 7L to equalize the y ows on the ns, substanpractically to the form anently ser end, c', is
