ANNA WEISSE'NBORN, OF NEW YORK, N. Y.
Letters Patent No. 65,141, dated .May 28, 1867 reissue No, 3,491, dated June 8, 1869.
IMPROVEMENT IN TUCK-CREASING ATTACHMENT I'OR'SEWINQMACHINES.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern Be it known that I, ANNA Werssnunonn, of the city, county, and State of N ew'York, have invented a new and useful Improvement in Tuck-Markers or Oreasers; and I do hereby declare that the following is a. full and exact description thereof, reference being had 'to the annexed drawings, making a part of'this specification, in which Figure 1 represents a top view of my invention.-
Figure 2, a side view of the same.
Figures 3 and 4 show a modification of my invent-ion.
Figures 5 and 6 represent 'a simpler application of my invention, using the spindle of the marking-wheel as a spring.
Figures 7 and 8 show a different form for a bearing of the marking-wheel.
Similar letters of reference indicate corresponding parts in all the figures.
The object of myinvention is to construct a tuckcreasing device, which may be attached to a sewingmachine, and enable the operator to crease the cloth, during the process of sewing, for different sizes of hem, or tuck; and to this end,
It consists in a sliding blade, having an upturned edge, that is secured to and moves with a bar, carrying a grooved wheel, that presses directly on the upturned edge. I
To enable others skilled' in the art to construct tuck-creasers according to my invention, 1 will proceed to describe the same, with reference to the drawmgs.
A is a metallic gauge-plate, of suitable shape, a1rd provided with a slot, A, through which the screw that secures it to the sewing-machine is passed.
This plate has upright lugs A, that serve as bearlugs for a pin, on which the lever-A turns,
A is a guide and bearing, fast to the levc) A, and which serves as a bearing for the spindle-A", which is held in position by the set-screw A The spindle A is'provided atone end with a groove, A and the spindle in this groove is flattened at its sides, tofit into a slot' in the upturned end A of the sliding blade'A". This prevents-the spindle from turning, and attaches the spindle and blade, so that they slide in either direction together.
A grooved'wheel, A'", is attached to the other end of the spindle, by means of the collar A and nut A", so as to turn freely on said spindle.
The sliding blade A" moves in a groove made in the under side of the fixed gauge-plate A, and has, on its extreme'cnd, an upturned edge, A, on which the wheel A l. is pressed down, by means of the spring A,
which is attached to the lever A and may be regulated by the set-screw A spindle-guide A Figs. 5 and b show still another mode of. construction, by dispensing with the spring and constructing the spindle in. such a manner as to serve the purpose of the spring.
Figs. 7 and 8 show a different construction of the spindle-guide.
The operation of creasing is accomplished by passing the cloth between the grooved wheel A and the edge A.
Instead of a grooved wheel, an edged wheel might be substituted, and the end of the sliding blade be turned up into a groove.
hat I claim, and wish to secure by Letters Pat-'- ent, is-
l. The combination, with a stationary gauge-plate A, of the movable blade A", having a creasing edge, A, andthe creasing-wheel A or their stated equivalents, when the said blade and wheel are connected together and adjustable in relation to the gauge, substantially as described. v
2. In combination with the above, a spring, substantially as described, for pressing the wheel against the edge.
3. In combination. with the elements of'the first clause, the wheel-elevating devices A B.
4. The combination, with a stationary gauge-plate and with creasing-mechauisn1, substantially such as described, counected'together and adjustable thereon, of a set-screw, for confining the said creasing-devices in proper position with the gauge.
