IMPROVEMENT IN RUFFLING-MACHINES.

Specification forming part of Letters Patent No. 126,436, dated May 7, 1872.

To all whom fit may concern:

Be it known that we, SAMUEL E. BARNEY and EDWARD HUBBELL, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Ruftling-Machines; and we do hereby de- Clare the following, when taken in connect-ion with the accompanying drawing a-nd the letters ot' reference marked thereon, to be afull, clear, and exact description of the same, and which said drawing constitutes part of this specification, and represents in- Figure l, a top view of the upper works of a sewing-machine, a portion broken away. Fig. 2, a sectional view of the machine on line :c showing a side view of the improvement; and in Fig. 3, a diagram showing the article to be produced.

This invention relates to an improvement in mechanism for forming plaits in frilling-machines, the object being to lay the paits diagonally; and the invention consists in imparting to the knife or plaiting device a combined longitudinal and transyerse movement, as more fully hereinafter described.

A is the bed-plate of the machine, the sewing mechanism employed being, by preference, that known as the Wilcox t Gibbs machine. B represents the post or arm; C', the needlearm; D, the connection between the drivingshaft and needle-arm, all substantially as in the Wilcox & Gibbs sewing-machine. Eis the presser-foot; a b, the two needle-holes, it being understood that this machine carries two needles, substantially as in the patent granted to Henry Kellogg and C. C. Crosby, December 2, 1862, except that, in this case, the needles are in a line diagonally across the workplate, the angle of the needles corresponding to the angle on which the plait is to be laid. F is the work-plate, the feed working through the work-plate, one at each needle, in substantially the same manner as for the single nee dle in the Wilcox 8a Gibbs machine. L is what we term the knife, it being a sharp edged plate, which, taking the fabric back of the needles, carries it forward, and doubles it under the presser-foot to form the plaits. The

longitudinal or advancing movement of this knife occurs at the time each plait is to he made, in substantially the manner as in the said Kellogg 8f Crosby machine. This motion is imparted from the cam L1, on a shaft, L2, which is driven from the shaft C by gears, as seen in Fig. 1. This cam, by a rod, L3, and an arm, L4, imparts a rocking motion to the shaft L5. 0n this shaft L5 another arm, L6, connect-s to the knife, as seen in Fig. 2; hence each operation of the cam Ll imparts a forward-and-back movement to the knife L. The requisite pressure is given to this knife by a presser-foot, P, actuated by a cam, P1, through a rod, P2, and the rock-shaft, P3, to which the said presser-foot P is attached, the cam operating to bear down the presser-foot P when the knife is carrying the fabric forward, and to release it on its return.

Thus far the operation of making the plait is substantially the same as in the said Kellogg 85 Crosby patent, it being understood that in that patent the plaits are laid at right angles, and that edge of the knife consequently lies at right angles across the work-plate, instead of diagonally, as in this invention. The fabric passes into the machine in a diagonal line, as denoted by the plain fabric S in Fig. 3; but after it is presented to the needles it passes on in a line atright angles to the shaft.

In laying the plaits, if the knife, taking the fabric on the line f, moved only directlyforward, the plaits would be laid in the usual manner, and not diagonally; therefore, to carry the fabric to one side, in order to make the diagonal plate at the same time the knife advances, we impart to it a transverse movement, which is done by arranging the rockshafts L5 and P3 upon a carriage, li, working in a longitudinal guide, R1, and this carriage is actuated by the cam R2 through the lever R3, so that at the proper time-that is, when the knife advances-the carriage It is moved longitudinally, carrying the shafts L5 and P3 and the knife Lto the left, as denoted in broken lines, Fig. l, which lays the diagonal plait as denoted in the diagram, Fig. 3.

Ve have represented the invention as employing two needles, which would make a line of stitches near each edge, and in this partieular class of plniting this is desirable; but transverse movement, substantially as herein for a frill only one line of stitches would be described.

required, yet the movement of the plaiiting de- SAML. E. BARNEY. .vice must be the same. EDWARD HUBBELL.
