IMPROVEMENT IN MARKING-ATTAUHMENT FOR SEWING MAGHINES.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, R. H. ST. JOHN, of Belle'fontaine, in the county of Logan, and State-of Ohio, have invented'a new and improved Marker-Attachment to Sewing Machines, for quilting, tucking. ctc. and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of thisspecification. v

The present invention relates to an attachment for sewing machines for the, purpose of marking the cloth at the points where it is to be folded for tucking, quilting, or for any other purpose, the attachment embraced in the present invention being so attached to the resser-foot or any other suitable part of the sewing machine,

and being so constructed as to be operated by the necdlc-bar, as the needle which it carries passes down through the cloth in a manner as will be hereinafter described, reference being bad to the accompanying plate of drawings, in which- Figure 1 is a plan or top view of the attachment for marking the line of tucks applied to the pressure-foot of -a sewing machine, and i i i i Figure 2 a rear elevation of one side o'f the same.

Similar letter'sfof reference indicate like'parts.

A, in the drawings, represents the resser-foot of the sewing machine, to which a holder, B, is attached in any suitable manner, ,it being shown in the present instance as placed in and between the two prongs or arms C of the resser-foot. This holder B is provided for the attachment of devices constituting the present invention, for marking the line at which the cloth is to be folded to'forrn a tuck in it, or to be quilted, etc. Through the holder B, in a direction at right angles to the length of the presser-foot A, or in other words at right angles to the direction in which the cloth' passes through the machine to the needle-bar, extends a horizontal shaft or spin 10, E, turning in suitable bearings of the said holder, formed in its two parallel upright arms or ieces F, and provided at one end, G, with a curved arm, H, suitably sharpened at itsouter end I, to form a crease or indentation, as it were, in the cloth without cutting or severing or in any other manner injuring'its fibres or threads. To the spindle E, between the uprights of the holder, is secured by a set-screw, J, a dog or foot-piece, K, made of a curved shape, and eiitending over the top of the resser-foot into the same vertical plane as the vertical movement of the needle-bar, so thatwhcn such bar is depressed it will strike against the same,

'and thus through it turn the spindle E to which it is secured sufficiently to bring the marking-arm of such 'spi'ndle to and down upon the cloth for marking-or indenting it.

i From the description above it is plainly bvious that as the cloth being served passes through the machine the needle-bar, every time it'descends to carry its needle through the cloth, acts upon'the dog or foot-piece K in the manner explained, thereby causing the said cloth to be at regular points of its length marked, as it were,

in a continuous line, or, nearly so, parallel to the line of the stitches being made in the cloth, by which line the cloth can be folded to form another tuck in it, when, as it is sewed, the line of the next tuck is similarly indicated, and so on, as long as may be desired, or according to the extent of the cloth.

To adjust the marker to any width of tuck within its ezitent, it is only necessary to unscrew the set-screw J and slide thespindle through the holder and dog or foot-piece K, either more or less, according as it is desired to mark a wide or narrow tuck upon the eloth, and there secure it by tightening the set-screw J.

To prevent any undue strain upon the tuck-marking attachment by the needle-bar, I have secured to the surface of the dog or foot-piece K, against which the needle-bar acts, a hentspring, M, which spring, in case of any obstruction or for any other cause,-yields, as it were, and thus relieves the ,marking-attachment of any strain without interrupting the downward'movement of the needle-bar, as is obvious.

In lieu of attaching the marking device to the Presser-Toot of the sewing machine, it may be secured to any other suitableiportion of the machine so long as it canbe operated by the needle-barin the manner explained.

And furthermore, the marking device may be used forpther purposes other than marking the line of tucks, as,

for instance, for quilting, etc., and therefore I do not intend -to limit myself to any one use of the same in connection with ase'wing machine.

What I claim as new, and desire to secure by Letters Patent, is- The spindle E,'having dog or foot-piece K, marker H, spring M, screw J, holder B, and presser-foot A, when constructed and arranged as herein set forth for the purpose specified.

Thcabovc specification of my invention signed by me this 8th day-of October, 1866.
