GUIDE FOR INTRODUCING CORDED WELTS INTO STITCHED SEAMS.

SPECIFICATION forming part of Letters Patent No. 792,116, dated June 13, 1905.

Application filed December 19, 1903. Serial No. 185,863.

To (all whmn, it flea/y concern:

Be it known that I, OTIs E. BROWN, a citizen of the United States, residing at Brockton, in the county of Plymouth, State of Massachusetts, have invented a certain new and useful Improvement in Guides for Introducing Corded Velts into Stitched Seams, of which the following is a specification, reference being had therein to the accompanying drawings.

I will describe my invention with the aid of the drawings, in which latter I have shown an embodiment thereof.

In the drawings, Figure 1 shows in elevation portion of the work-support of a sewing-machine having applied thereto the said embodiment of the invention. Fig. 2 represents in plan the parts which are shown in Fig. 1.

My device is provided with a weltguide that is adapted to double the welt upon itself lengthwise and conduct the same between the two pieces of material which are being stitched together and with a cord-guide that is adapted to conduct a cord into the bend of the doubled welt between the two sides of the latter. The cord-guide in its normal or working position is located within the inclosure of the welt-guide, the two portions of the welt passing, respectively, above and below the cord-guide.

Having reference to the drawings, the top portion of the work-support of a sewing-machine is represented at 1.

2 is the opening or throat through which the needle of the sewing-machine operates.

3 is a worlegage of usual character placed upon the work-support 1 and against which the edges of the pieces of material which are to be stitched together are caused to bear to determine the distance of the line of stitching from the said edges. The said gage is secured to the work-support, with its working edge at the required distance to one side of the throat 2, by means of the clamping-screw 31, the stem of which latter passes through the slot 32 of the plate of the said work-gage and enters a screwthreaded hole that is tapped into the work-support 1.

The attaching-stand of my device is designated 4. It is mounted upon the top of the work-support 1 and is secured in place there on by clamping-screws 41 41. The stems of the said screws pass through slots 42 42, that are formed in the stand 4, and enter screwthreaded holes that are tapped in the worksupport 1. The slots 42 42 provide for ad j ustment of the attaching-stand and the parts which are connected therewith transversely with reference to the needle and needlethroat of the sewing-machine. The attaching-stand 4 is provided with an arm 5, which projects therefrom toward the position of the needle and the needle-throat. To the said supporting-arm 5 the carriers, hereinafter described, of the guiding members are connected.

The main portion or body of the weltguide is designated 6, and the cord-guide is designated 7. The said main portion or body 6 of the welt-guide is secured to a carrier, which is designated 61. The welt is passed through the said main portion or body. The latter operates to fold or double the welt upon itself longitudinally as the welt is drawn through the interior space thereof, and hence constitutes the turning member of the welt-guide. The welt-guide is furnished with an edge-guiding member 8, which acts against the edges of the two side portions of the doubled welt. This edgeguiding member is constituted by one end of a bar 81, the said end being bent forward and inclined toward the closed end of the body portion 6 of the welt-guide, so that its acting surface converges toward the said closed end of the body portion 6. Thebar 81 is mounted upon the carrier 82. For the purpose of enabling the welt-guide to be adapted to the width of the welt which is being operated upon provision is made for effecting the adjustment of the edge-guide 8 thereof in a direction toward and from the closed end of the body portion of the welt-guide. To this end the bar 81 is connected with the carrier 82 in a manner permitting the bar to be adjusted in the direction of its length upon the said carrier.

The means of effecting the adjustment may be varied in ractice. In the drawings I have shown tie carrier 82 formed with a clamp to receive the bar 81, the clamp and bar being constructed to enable the bar to be shifted into different positions within the grasp of the clamp. The clamp is formed by providing projections 821 821 at the top and bottom of the end of the carrier 82 to engage with the upper and lower edges of the bar and by slotting the carrier horizontally for a short distance inward from its free extremity, as at 822, producing thereby a split clamp, a screw 823 being provided, in connection with the u )per and lowerportions of the said clamp, for the purpose of enabling the said portions to be tightened upon the bar. To assist in holding the bar 81 securely and steadily in the required position, the edges of the portion of the said bar which is engaged by the clamp and the jaws of the clamp themselves are dovetailed to fit one another.

The cord-guide 7 is mounted upon the outer end of the bar 8] and extends forward through the opening of the body 6 of the welt-guide, its delivery end or nose projecting forwardly beyond the said body toward the needle and being located in proximity to one end of the needle-throat 2. As thus sup ported the cord-guide occupies a position between the upper and lower sides of the doubled welt as the latter is drawn through the welt-guide and operates to conduct the cord into the bend of the welt. For the purpose of causing the cord to be pressed fully home into the said bend the cord-guide 7 is mounted with capacity for independent movement with relation to the closed side of the body portion of the welt-guide and. is actuated with yielding force to press the same toward. the said closed side. The said capacity for independent movement with relation to the closed side of the welt-guide is secured by movably connecting the cord-guide with the bar 81. In the present instance the cordguide is connected pivotally with the said bar at its forward end, as at 71. The yielding action is secured by means of the spring 72, one extremity of which is engaged with the laterally-projecting lugs 7 3 of the cordguide, while the other extremity thereof is secured to the bar 8] by means of a clamping screw 74. The cord-guide occupies a horizontally-inclined or oblique position with respect to the line of feed, so that the cord may be delivered from the discharging end of the passage therethrough home into the bend or bight of the longitudinally-doubled welt on its way to the needle. In order to insure that the cord shall be pressed fully home into the said bend or bight, as well as to hold the same there in close proximity to the needle, the nose portion of the cord-guide is extended some distance beyond the said discharging end of the passage through the cord-guide toward the needle. Thus the cord is held in place with certainty until secured by the convenience in threading a cord through the cord-guide 7 whenever such operation becomes necessary and also in inserting the welt into position within the welt-guide I mount the cord-guide with capacity for movement bodily into and away from the body of the welt-guide, so as to enable the same when required to be withdrawn from within the inclosure of the body portion of the welt-guide and out from between the upper and lower sides of the doubled welt into a position in which it is exposed and fully accessible to the operator and in which it is somewhat widely removed from the said body. The with drawal is by a movement backward from the needle toward the operator and also laterally away from the line of the seam in a plane parallel with the upper surface of the work-support. The capacity for movement in such plane enables the cord-guide to be moved readily into position again between the two sides of a doubled welt occupying the body of the welt-guide. The manner and means of mounting the cord-guide may varyin practice. In the present embodiment of the in vention the edge-guide 8 of the welt-guide also is arranged to be withdrawn backwardly and laterally, so as to render the inclosing portion or body of the welt-guide wholly unobstructed and entirely open at one side, whereby it is rendered more convenient for the operator to insert a welt into the body of the welt-guide and it also is rendered possible for the said welt to be passed in doubled form by hand transverselyinto the said body, if desired. In the said embodiment, in which the cord-guide and the edge-guide 8 have a support in common, which I prefer, the said support being constituted by the bar 81. aforesaid, the carrier 82 for the said bar is movably connected with the supporting-arm 5 by means of a vertical pivotal pin 9. The said carrier may be swung in a horizontal plane around the axis of the said pivotal pin from the working position of the parts, which is shown in Fig. 1, into an inoperative position, in which the cord-guide and edge-guide are withdrawn from the body of the weltguide toward the right-hand side in the drawingsi A suitable latching device is provided for holding the carrier and parts which are mounted thereon in their working position with relation to the body portion of the weltguide, the said latching device consisting in. the present instance of an elastic arm 824, which is notched to engage with a fixed pin 825, rising from the horizontal extension of the body portion 6 of the welt-guide.

On arriving close to the end of the seam which is required to be produced it is necessaryin practice to cut the welt and cord, then withdraw the welt-guide and cord-guide and complete the remaining portion of the seam after the withdrawal, so that the end of the stitches which. are formed by the needle. F or l welt, with its inclosed cord, may be sewed ICC properly into the seam. In order to effect the withdrawal of the welt-guide and cordguide, I mount these parts so as to render them movable in unison into and out of working position in a plane parallel with that of the worksupporti 6., in substantially the plane of the material which is being operated upon. To this end the carrier 61 is made movable about the axis of the pivotal pin 9, like the carrier 82. In the present instance the said pivotal pin is formed upon or fixed to the carrier 61, the carrier 82 having an eye or bearing which is fitted to a portion of the pivotal pin immediately adjacent the carrier 61, the pivotal pin also fitting a bearing with which the supporting arm is provided. For the purpose of holding the carrier 61 locked in the working position an arm 91 is fitted upon the upper end of the pivotal pin 9, so as to turn in unison with the latter, and a projection or lug 51, rising from the supporting-arm 5, is formed or provided with opposite projections 52 52, having intermediate them a depression or notch which re ceives the said arm 91 in the said normal position of the carrier 61. Thereby the carrier 61 is held latched in the working position, and by means of the latching device by which the carrier 82 is latched to the welt-guide the parts that are mounted upon the two carriers are retained in their proper relative position. Upon springing the latching-arm 91 upward out of the notch between the projections 52 52 the two carriers may be swung in unison, so as to retract the welt-guide and cordguide from their working position in proXimity to the needle-throat 2.

In order that the cord-guide and welt-guide may be sewing entirely out of the way when the use of the device in its entirety is to be temporarily discontinued, the supporting arm 5 is connected pivotally, as at 53 53, with the attaching-stand 4. This enables the said arm and the parts which are carried thereby to be thrown back out of the way by movement in a vertical plane.
