PAD-STITCHING ATTACHMENT FOR SEWING-MACHINES.
PECIFICATION forming part of Letters Patent No. 390,685, dated October 9, 1888.
A Application filed May 26, H388. Serial No. 275.209. (No model.)
To all whom it may concerm Be it known that I, FRANCIS W. M ALLETT, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Pad-Stitching Attachments for Sewing-Machines, of which the following is a specification, reference being had therein to the accompanying drawings.
The object of my invention is to provide a convenientsewing-machine attachment whereby circumvoluted scams may be formed in circular pads of cloth or similar material. To this end I mount on a suitable standard or support attached to a base-plate a sliding tube within which is a screw-shaft having at its forward end. a bevel-gear extending within a housing at the forward end of said tube, said bevel-gear being connected by a train of gearing with a disk arranged beneath said housing and adapted to be connected with two rotary disks, between which the plies or thicknesses of material to form the pads are to be clamped. A toothed dog or locking device, which may be engaged with the screw-shaft, will cause a slow longitudinal movement of the said shaft and the sliding tube within which it is mounted, and thus of the parts connected with said tube, when the pad is rotated by the feed of the sewing-machine,thereby moving the said pad slowly laterally or at right angles to the direction of movement of the feed and causing ascroll-like or convoluted seam to be formed in the pad. \Vhen the stitching is completed, the sliding tube and connected parts may be turned up on the pivotal support of said tube to be clear of the padholding disks, to permit the pad to be removed. The locking device is then disengaged from the screwshaft, permitting the sliding tube to be adjusted to its first position preparatory to stitching another pad, and the said locking device will then be re-engaged with said shaft for the new operation.
In the drawings, Figure 1 is a side elevation of my attachment, showing, also, a portion of a sewing-machine with which it is connected. Fig. 2 is a plan view of the same. Fig. 3 is a plan view of the attachment, and Fig. 4 is a sectional elevation thereof. Figs. 5, 6, and 7 are detail views, to be referred to.
A denotes the work-plate, B the bracketarm, 0 the needle-bar, and 0 the needle, of an ordinary sewing-machine.
D is the base plate of the attachment, to be secured to the sewing-machine work-plate in any suitable manner, or it may be an extension of said work-plate. The base-plate D is provided with standards (I, on which is pivotally supported a shaft or bar, 'E, having at its center the hollow cross-piece c c. e of the said cross-piece receives a sliding tube, F, having at its forward end the hous ef- G is a scrcwshaft mounted in the'said sliding tube and provided at its forward end, within said housing, with the bevel-gear h, meshing with the bevel gear h on the shaftlfi, said shaft h carrying also the gear 7L ,I11Sh1ng with the gear If on the shaft h having the disk h and the centering-pin 727.
I denotes a pad consisting of a number of The part plies of cloth or other material which are to be stitched together by a convoluted seam. Said pad is held between the disks 1; and t the disk t" being provided with a sleeve, t, on which the disk i screws to clamp the pad, the latter having a central hole through which said'sleeve passes. The disk 2' is engaged by pins h on the disk h, the centering-pin lientering the sleeve The tube F is provided on its under side with a longitudinal slot, f, through which the toothed portion k of the dog or locking device K (shown in detail, Fig. 5) can pass to en gage the screw-shaft G. The said dog or looking device is attached to an arm, m, having rigid stud m, Fig. 6, which has a bearing in a support or bracket, or, attached or forming part of the cross-piece c e, the said stud being provided with an operating-handle, m". (Shown in detail in Fig. 7.) WVhen the parts are in the operative position shown in the drawings, the teeth of the dog or locking device will be in engagement with the screwshaft G, so that when the latter is rotated the stationary dog will cause a longitudinal movement thereof and of the sliding tube and connected parts; but if the handle an be moved to the left the said dog will be depressed out of engagement with said screw-shaft, thus leaving the tube F free to he slid lengthwise through the sleeve or part c of the hollow CIOSSPIGCG.
The operation is as follows! The plies of material are secured between the disks 2" and i and placed in operative position, as shown in Figs. 1, 2, and 4. The machine being started, the feed thereof, acting on the pad I, will rotate said pad and thus turn the screw'shaft which is connected. therewith, as shown in Fig. 4:, thereby causing said pad to be moved slowly laterally to the right as it is rotated, so as to form a convoluted or scroll-like seam, as indicated by the dotted circular lines in Fig. 2. When the stitching of the pad has been completed, the handle an is moved to the left, dis engaging the locking dog from the screwshaft, and the latter is then turned up on its pivotal support to disengage the pin 71. from the sleeve of the pad-holding disks and slid to the left preparatory to repeating the stitching operation with another pad.
Having thus described my in vention,I claim as new and desire to secure by Letters Patent- 1. A sewing-machine attachment consisting of the co1nbination,with a base-plate and padclalnping disks, of a sliding tube pivotally supported on said base-plate, a screw-shaft in said tube, a train of gearing connecting said screw-shaft with said disks, and a locking device to engage said screwshaft and cause it to move longitudinally when rotated.
2. A sewingmachine attachment consisting of the conibination,with a base provided with standards, of a shaft pivotally supported by said standards and provided with a hollow crosspiecc, a tube fitted to slide through one portion of said cross-piece, a screw-shaft in said tube, pad-clamping disks, a train of gearing connecting said screw-shaft with said disks, and a locking device supported by said crosspiece and engaging said screw-shaft to cause the latter and the parts connected therewith to move longitudinally when said shaft is rotated.
3. A sewing-machine attachment for scrollstitching pads by a convoluted seam, the same consisting of the combination, with the base; plate D, having the standards d, of the bar or shaft E, pivotally supported on said standards and having the hollow cross-piece e e, the tube F, fitted to slide through the said crosspiece and provided with the housing f, the screw-shaft G in said tube, the connectedpadclamping disks i i the disk It, having acounection with said pad-clamping disks, a shaft, 7L5, by which said disk h is carried, a train of gearing connecting said shaft IL5 with the said screwshaft, the toothed locking-dog K, the arm m, having the operating-handle m". and the bracket to which said arm is pivoted.
In testimony whereof Iaiiix my signature in presence of two witnesses.
FRANCIS W. MALLETT.
