IMPROVEMENT IN TUCK-MARKERS.

Specication forming part of Letters Patent N o. 170, 154., dated November 23, 1875; application led May 15, 1875.

To all whom 'it may concern:

Be it known that I, RICHARD G. BUSH, of Jamestown, in the county of Chautauqua and State of New York, have invented certain Improvements in Tuck-Markers for Sewing-Machines, of which the following is a specification:

The object of my invention is to produce a simple and efficient device for creasing the cloth for one tuck while another is being sewed; and consists in using, in combination with a bed-plate with an upturned point or blade over which the goods pass, of a narrow eXible finger or blade arranged on one side of the bed-plate above named, and a hook so made and arranged that it shall simultaneously engage -the opposite side ot' said blade and the exible finger or blade and draw them tightly together.

Figure l is a plan, complete, of a tuckmarker embodying my invention. Fig. 2 is a side elevation of same. Fig. 3 is an end view.

A is the gage for regulating the width of tuck, and is also provided with a th Limb-screw, B, by means of which the bedplate C, through a slot in same, is attached to and adjusted upon it. Near one end of this plate is an up turned blade, c, and at the opposite end are attached the cloth-holder d and the spring-arm b, which is operated by the needle-bar of a sewing-machine by means of the hook c. A bolster, e, is inserted between the cloth-holder d and the bed-plate C for the purpose of holding the two plates apart and to strengthen the attachment. The cloth-holder d extends parallel with plate C as far as the blade a, and then turns and is suspended over it with a projecting lip on either side, which are bent downward, as shown at h, to engage the blade a and finger j, and draw them tightly together. This finger is made to lie loosely on plate C, parallel with and directly to one side ot' blade a, and is'held in position by passing through a slot in the projecting portion of holder d, and is secured by a loop, '11,011 the same at right angle therewith.

In practical operation, the cloth to be tucked is folded the rst time and placed over the blade a and under the clothe-holder d and finger j, back against the gage A. Now, as the needle descends to its lowest point the hook h and finger j' are made to engage the goods lying on blade a, pressing it tightly together over the bladeand forming a crease.

I claim- The combination of the blade a, over which the goods pass, with the linger or blade 7' and hook h, arranged to pinch the goods lying on the same, all constructed and operating substantially as and for the purpose described. RICHARD G. BUSH.
