UNITED STATES PATENT OFFICE.
Specification of Letters Patent.
Patented Oct. 24, 1'au5.
Application filed January 26, 1905. Serial No. 242,715.
To all whom itmoty concern:
Be it known that I, JOHN M. Gamer, acitizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented or discovered certain new and useful Improvements in Sewing-Machine Rufiiers, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to that class of sewing-machine rufliers which are operated from the needle-bars of the machines; and the invention has for its object to provide a rufiier of the class referred to in which the regulating mechanism, by which the throw of the ruiiiing-blade may be varied, will be simple in construction and eflicientin operation. To this end the secondary lever, which operates the rutiiing-blade and which is to be actuated from the main or needle-bar lever, is provided with suitable stops or projections to be engaged by stops on a regulating-dog moving with the needle-bar lever, but capable of adjustment to vary the amount of lost motion between said needle-bar lever and secondary lever through the medium of an eccentric device movable with the said needle-bar lever when the ruiiler is in operation, but capable of being turned or adjusted independently of said lever.
In the accompanying drawings, Figures 1 and 2 are side and plan views, respectively, of the improved ruffler. Fig. 3 is aside View of the same with the ad justing-washer and its attached cap or disk removed. Fig. 4 is a section on line 4 4, Fig. 1. Figs. 5 and 6 are detail views of the secondary and main levers, respectively. Fig. 7 is a detail view of the regulating-dog, and Fig. 8 is a detail view of the adjusting-washer or disk to show its eccentric slot.
Referring to the drawings, the frame of the attachment comprises a presser-foot 12, its shank 13, and the standard 1 1, which parts are preferably integral; but they may be rigidly secured together. The main or needlebar lever and the secondary or ruiiiingblade operating-lever 16 are pivoted on a stud 17, supported by the standard 14:, said lever 16 being connected by a pivot 18 with the carrier 19, to which .the rufiiing-blade 20 is secured, and said ruiiling-blade cooperating in the usual manner with a separator-plate 21, secured to a holder 22, detachably connected to the frame of the ruflier.
The hub portion of the secondary lever 16 is provided with stops or projections 23, and the hub portion of the main or necdle-bar lever 15 is provided with a circular slot or recess 24, the upper part of which loosely receives the said stops or projections, and in the lower part of which is arranged a pivoted dog 25, having shoulders 26, which cooperate with the said stops or projections 23, and which dog is provided with a lug or projection 27, entering an eccentric recess 28 in'a washer 29, attached to or integral with an adjustable disk 30, having a serrated peripheral portion 31 to be engaged by a small lug or projection 32 on a spring-plate 33,connected with the said main or needle-bar lever 15 so as to move therewith, said lug or projection 32 serving to hold the washer 29 and disk 30 in any position relative to the said lever 15 to which they may be adjusted. The pivoted dog 25, arranged in the recess 24 of the lever 15, is entirely out of sight, being inelosed or housed in said recess between the lever 16 and the washer 29, the construction being simple and compact and contributing to a neat and attractive appearance of the rufiier.
The lost motion between the main or needlebar lever 15 and the secondary lever 16 may be varied simply by turning the disk 30 and the washer connected therewith, so that the eccentric slot or recess of the said washer 29 i will move the regulatingdog in or out, and thus vary its working position, as may be desired, to bring the shoulders or stop portions 26 thereof nearer to or farther from the stops or lugs 23 on the said secondary lever 16, and as the said regulating-dog swings from its pivotal portion 31 in being thus adjusted both of said stop portions or shoulders 26 will be simultaneously adjusted, although one will have a greater adjusting movement than the other, so that the throw of the ruiiiing-blade will be regulated ,at both ends of its stroke; but the adjustment for the forward throw will be less than the adjustment for the backward throw as measured from the central or middle part of the movement of said blade.
Having thus described my invention, Ielaim and desire to secure by Letters Patent 1. In a sewing-machine rufller, the combi: nation with a ruflling-blade and main and secondary levers by which said blade is operated, of fixed stops on one of said levers and an adjustable inelosed regulating dog on the other of said levers affording stops cooperating with the first-named stops, and a rotatable device provided with an eccentric slot for changing the working position of the said regulating-dog to vary the throw of the said ruffling-blade.
2. In asewing-rnachine rufiler, the combination with the rufliing-blade and its carrier, of the main or needle-bar lever 15 having the circular recess 24:, the pivoted dog 25 located 111 said recess and having a lug or projection 27, the secondary lever 16 having the lugs or stops 23 projecting into said recess, the adjustable washer 29 having an eccentric recess into which said lug or projection extends, and means for holding said washer in any desired position of adjustment.
3. In a sewing-machine ruflier, the combination with the rufliing-hlade and its carrier,
of the main or needle-bar lever 15 having the circular recess 2a, the pivoted dog 25 located JOHN M. GREIST.
