TO ALL WHOM IT MAY CONGERNL' I p Be it known that I, EDWARD BosrocK, of the city ot Albany, county of Albany, and State of New York,
have invented certain Improvements in Tuck-Creasers; and I do hereby declare that the following,'talren in connection with the drawingswhich accompany and form part of this specification, is a description of my invcntion suflicient to enable those skilled in the art to practise it. l y
- My invention relates tothat class of implement designed for indenting a well -defined'crease in fabrics, preparatory to folding down and stitching the same, in the formation of tucks, andis intended for either hand or machine-sewing. It is more particularly useful, however, in sewing by machinery, and will,.therefore,be described with reference theretc.. i
The 'object of my present improvements is to render such devices more generally and practically useful;
. than they have hitherto been, by making them of fewer parts or pieces, impartingto theui' greater certainty and efficiency of action,-adap ting them. for creasing the finest fabrics without danger of cutting, and yet with but little pressure or drag," rendering the creasing-edge more permanent and durable, and in so constructing them that, instead of being capable of use upon only one class or style of machine, they may be used sucoesis fully upon all the leading and most popular machines in the market, viz, the Howe, Singer, Grover and Baker? ,ll'eed wheeler and Wilson, Elliptic,Florence wilcoxand Gibbs, and others l Y My present invention is also an improvement upon some of the features of my tuck-creaser, patented to' May 7,1867, and hich Letters Patent are numbered 64,404, nd is simpler in construction, and more.
reliable in action. p I
Figure 1 represents my improved creaser applied to a Howe machine. Figure 2, the same,'as adapted to a Wheeler and Wilson machine.
Figure 3 represents a modification of the pressure-adjusting device. Figures 4 and 5 represent other modifications of the pressure-adjusting device. The other figures represent some of the details more clearly. Similar letters refer to the same parts in the difl'erent figures. Y i A is a thin flat metal plate, shaped substantially as shown in fig. 1, when designed for use upon the Howe, Singer, Grover and Baker, Weed, and similar machines in which the direction of the line of feed is forward from the operator, and shaped as shownin fig. 2, that is, with one of its sides at an angle of from five to thirty degreesto the line of the arm which supports iliecreasing-wheel, when designed for use upon the Wheeler Wilson, Elliptic, and other machines in. which the line of feed -is from the left to the'rightdiand side o'f'the operator. This plate, as well as the other parts of the creaser, is shown in the drawings of full size, as made and adapted for useupon the machines. a
B represeiits the gauge-plate; C, the usual thumb-screw, but which secures both 'plates, A and B, to the table at the same timej D, a slottedadjusting-wedge, for graduating, at will, the pressure of the creasing-wheel upon the creasing-edge; E, a yoke or stand, for the reception of the wheel-supporting arm and the wedge D F, the grooved wheel; G, the creasing-blade or edge, which acts in conjunctiori with the wheel; H H, slots in both plates, to. admit of their adjustment relatively to'thc needle and to each other; I, a straight guiding-edgeupon plate B, for the folded fabric; K, a projecting lip or tongue, beneath whichthc folded edge passes, and by which the fold is kept flattened; L, a scale on plate A, to serve as a measure of the width of fold, andof the distances that the wheel and thestraight-edge should severally he set from the needle; M is a downwardprojecting part of guiding-edge I, so that the same shall he flush with and rest upon the table.
Instead of making the creasing-edge G bymerely turning up the end of the plate A, or by indenting the same from beneath, so us'to form a ridge, and'which can only he done with comparatiirelysoftmetal, I first cut across-groove near the end of the plate, and then solder therein a strip of case-l1ardened iron orsteel, whose edgehusjbeen first sharpened almost to a cuttirug-edge, and then finished with emery, or otherwise, so as to leave it as smooth and as sharp as possible, without danger of cutting the finest fabrics which mayp'ass-ovcr it. y This some 3 screw-holes, which extend not only through the cloth-plate, but also to a considerable depth into each of these posts. The right-hand back screw-hole is generally used for such purposes, unless tharattachment, whatever it may be, be secured 'to the vibrating-needle arm. The position of this screw-hole, however, relatively to the forward end of the presser-foot, and to the corresponding forward end of the slot, through which. the feeding dog rises, is such that my form of creaser, (as well as all others,) adapted for a feed in the direction of that shown in .fig. 2, would not be available in the class of machines shown in fig. 1, because, as will be seen at a.
glance, and as will readily be understood by all familiar with sewing-machines, the implement would require a position with which both the presser and the feed-slot interfere,-and to apply it to the machine wouldabsolutely prevent all possibility of sewing at all; but, by so shaping the plate A, and the slot therein, as that one side of the plate and the slot are at an angle of from five to thirty degrees to the line in which the wheel-supporting arm is placed, all diiliculty is removed. The degree of this inclination may'vary, according to the machintrt'o which it is to be adapted.
By reference to fig. 2, it will now be perceived that, whilst the wheel occupies its true and necessary position of parallelism with the line of stitching or feed, yet the plate A,f(although secured to the table at the screw-hole indicated,) by reason of this inclination of one of its sides,just clears the slot throughwhich the feed-dog rises, so as never to interfere with the feed, and, consequently, it also clears both the pres'rer and the needle. In adjusting the position of the creasing wheel nearer to or farther from the needle, preserving always,
Q ,of course, its parallelism with the line of feed, the relative position of--the edge of plateA which is nearest the feed is never changed relatively to it; hence, its adjustment is as simple as in the other form, shown in fig. 1, and with no liability of interfering with t e action ofthe sewing-machine. In thisinclined construction of my apparatus, I adopt theform of gauge-plate B, and its slot to it, as shown, and I form upon the outer side a descending flange, which servesalways to keep A and B in proper relative position, so that the straight-edge on I shall always occupy its true position for guiding correctly the folded edge of the fabric. The projecting tongue upon plate 13 admits, in this construction, of being made. broader, sons to confine'beneath it more of the surface of the folded edge; and this allows of an improvemenflwhich is found to, be ofgreat value, "and which consistsin cutting a long opening or slot in the tongue, the rear of which slot reaches to and comes flush with the vertical face of the straight-edge. The advantage of this feature is that thc operator, whilst the machine is working, and the crcascr is doing its work, can see, without obstruction of any intervening object, whether {the folded edge is being correctly guided (as it must be to do good work)close up to the straight edge. If, at. any time, it runs awry, her eye can detect and correct it. This cannot'be done without such opening, and, a before the prompt discovery of the first inclination to run aslant, the damage would be done to the work, and beyond remedy, except by taking the stitching apart, and re-sewing the work. i I
Some of the advantages of my improved crease; may be summed up as'follows 'It consists of but about seven pieces; can be adjusted for every width of tuck and crease by a single set-screw; the parts most liable to wear are made of hardened steel, and will not wear out by use; it. requires no oiling; it makes a fine sharp crease. on very delicate fabrics, and with a gentle pressure; the goods do not require to be washed before being tucked or creased; it is made entire, of the best material, and by machinery purposely devised for its manufacture, so that all of a pattern are precise duplicates of each other; its operation does not add appreciably to the power requiredto run the machine; and, by not interfering with the action of thc needle-bar, or other moving parts of themachinc, it will not'cause tlie machine to slcip stitches, run hard, or wear out, or strain the needle-bar, whilst, by touching the goods at only the contact points of a circle and a fine hardened-cdged-c'urve, the crease it makes is continuous, sharp, and yet made with as little resistance or. drag, is believed, as is possible to be attained.
The operation is as follows: The plates A and B having been secured to the bed-plate of the machine by the thumb-screw, as shown, the straight edge of B is to be set as far to theright of the needle as the width of the tuck required, and thecreasing-blade as far to the left of the needle as twice the width of the tuck from the needle added to the space required between two tucks. Thc'folded edge of the fabric is now to be placed against 1 the straight edge of gauge B, andunder the wheel, and, as a'rule, but very slight pressure given to the wheel.
The work should be kept straight, by hand, until it has passed the needle, as in ordinary sewing.
1. I claim the combination, with the tuck-creasing devices, of a sliding wedge, eccentric, or a slide-and" fixed inclined plane, on the base-plate, substantially as-and fcrthc purpose shown and described.
-2. I also claim, in combination, the spring-arm, and its creasing and pressure-adjusting devices, and the fixed standv or yoke E, substantially as and for the purpose set forth.
3. I also claim the tuck-creaser and its gauge-plate, constructed with their coinciding slots at an angle tothe c.casing-arm and line of stitching, as described, so that, when aillxed to a machine by means of the thumbscrew and screw-hole, and moved in a slantingdirection for adjustment, the parallelism of the line'of creasing with the line of feed may always be preserved.
4 I also claim the devices .herein described, the same constituting a tuck-:crca'ser, constructed as specified.
