SUSAN R. KNOX, OF NEW YORK, N. Y., FOR HERSELF, AND ASSIGNEE OF NV. D. OORRISTER.

IMPROVEMENT IN FLUTING-MACHINES.

.Speciiication forming part of Letters Patent No. 53,633, dated April 3, 1866; Reissue No. 3.861, dated March l, 1870.

To all whom it may concern Be it known that Mrs. SUSAN R. KNOX and WV. D. UORRISTER, of the city, county, and State of New York, invented new and useful Improvements in Flirting-Machines, and that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference bein g had to the accompanying drawing, forming part of this specification.

Ihisinvention relates to machines for makin g filming-trimming, so called, used by ladies in the trimming of their dresses, and'for flut ing the trimming of under-garments, &c. and consists in so arranging one of the two iiuted rollers (between which the material to be tluted, such as linen, lace, &c., is passed) that it can be readily raised or removed from the other, in order that the material passing between them can be removed therefrom; and, furthermore,it consistsin an arrangement of parts whereby the rollers can be adjusted with regard to each other so as to produce a greater or lesser pressure upon the material passing between them, as may be desired.

Heretofore, when desired to remove the material being fiuted by the rollers before it had entirely passed between them, it has been done by reversing the motion of the rollers, thus causing the material to travel back, the great objection to which has been that as the material repassed between the rollers there was necessarily producedirregularity in the luting, which, as is obvious, was exceedingly disadvantageous.

By this invention this objection is entirely obviated, as will be readily apparent from the following detail description thereof, the material being at any time and at any point of its length susceptible of an easy removal from the machine.

In accompanying plate of drawings our improvement is illustrated, Figure l being a plan or top view of the machine 5 and Fig. 2, a longitudinal vertical section, taken in the plane of the line at' w, Fig. 1.

a a in `the drawings represent the bed-plate of the machine, which may be either the top of a table, or a separate piece of wood, or other suitable material, at one end of which, b, are

two upright standards, o o, at a short distance apart, between whichone of the fluted rollers, d, is hung, turning at each end in suitable bea rings thereof 5' f, a standard-frame, placed somewhat back of the position of the iluted roller el, and securedto the bed-plate ain any proper manner, to which frame is hung, in a4 horizontal plane, a frame, g, so as to be freely turned thereon. In the outer end, h, of this horizontal frame g, and extending across the same, another fluted roller, l, (similar in size and shape to the roller 61,) is hung so as to turn therein, the corrugations of which roller l interlock with the corrugations in the roller below it, as clearly illustrated.

The frame g is held lirmly down, so as lto bring' its roller in close contact with the roller d, by means of metallic sprin g-plates m m, fastened at one end to thexed standard-framef, and both bearing by their other ends, u a, upon the cross bar or rod o of the frame g, between its roller l and its hinged end.

The pressure with which the frame-roller h is made to bear upon the roller d is regulated at pleasure by simply turning the thumb-screw pp, that holds the springs to the frame f, which through their head-plate q th us increase or decrease the stiffness ofthe springs, as the case may be, and as is evident without further explanalion.

In the upper end of the projecting arm 1^ of the standard-frame f is hung a lever, s, one end of which is provided with a suitable handle, t, while the other passes under the crossbar o of the horizontal frame g, so that by pressing down upon the handle end of the le ver the frame g is caused to be swung upward, thus lifting the roller Z from the roller cl, the frame, when the hand is withdrawn from the lever-handle, falling by its own weight, aided l by the force of the springs m 1n.

The hollow uted rolls being heated by inserted irons, or in any suitable way, the material to be luted is passed in and between the two uted rollers, motion being communicated to such rollers through a crank-handle, w, secured to one end of the lower roller, d, which motion can be continued till the whole of the material has been passed through them, unless desired to withdraw the same before bein g fully lluted, when the upper roller is raised, as before described, thus allowing the material to be readily removed, the advantages of which are evident to all.

The rollers d and l are so arrai'lged in their respective bearings that they can be easily deA tached therefrom, when desired to use rollers having larger or smaller corrugations, and as there are various Well-kncwn ways in which this can be accomplished, it is not deemed necessary to describe any one particular ar- I rangement.

v Having thus described the invention, What is claimed as new, and desired to be secured by Letters Patent, is-

l. Auting-machine in which the rolls can be readily disengaged from each other by mechanical means to permit the extrication of the material at pleasure, as hereinbefore set fort-h.

2. In combination with a stationary frame carrying one of the rolls, and a movable frame carrying the other roll, a variable springpressure device acting upon the movable frame, substantially as and for the purpose set forth.

MRS. SUSAN R. KNOX. [L. s.]'
