Application October 3, 1951, Serial No. 249,458

2 Claims. (C1. 112-218) 'I'his invention relates to sewing machines. More specically, it is concerned with sewing machines useful in attaching ornamenting threads or braids to outline or otherwise embellish design figures, for example, on stoles, chalice and alter covers, ecclesiastical garments and like articles used in churches and other religious establishments.

The chief aim of my invention is to provide simple and inexpensive means, in the form of an attachment for a sewing machine of the type referred to, whereby one or more ornamenting threads are directed from a source or sources of supply toward the stitch forming instrumentalities in such a way that said 'threads are attached to base fabric with concealment of the stitching except for longitudinally-spaced transverse overlapping binding portions of the needle thread.

Other objects and attendant advantages will appear from the following detailed description of the attached drawings wherein:

Fig. 1 is a view in front elevation of a sewing machine conveniently embodying my invention.

Fig. 2 is a fragmentary View of the machine, partly in front elevation and partly in longitudinal section, drawn to a longer scale.

Fig. 3 is a fragmentary view in transverse section taken as indicated by the angled arrows III-Ill in Fig. 2.

Fig. 4 is a fragmentary view in horizontal section taken as indicated by the angled arrows IV-IV in Fig. 2.

Fig. 5 is a perspective view showing how the ornamenting threads are sewed to the fabric by the machine; and

Fig. 6 is a perspective view of the presser foot of the machine.

The knitting machine herein illustrated is, generally speaking, of well known construction in that it has a bed plate ID and an over-reaching arm I l with a terminal head I2. The needle bar, indicated at I3, which carries the sewing needle I4, is constrained to up and clown movement in a frame I'5 pivoted at I6 within the head I2. Needle bar I3 reciprocated endwise through a link Il, by a crank I8 at one end of a drive shaft I9 journalled in suitable bearings within overhanging arm II. Shaft I9 protrudes from arm I I beyond the supporting column 20 of the latter and is provided with the usual hand wheel 2|, and also with a pulley 22 for power actuation, through a belt 23, from a suitable prime mover such as an electric motor (not shown). Frame I5 is oscillated about its fulcrum I6 through a horizontal link 24, for impartation of lateral vibrating movements to needle I 4, by mechanism concealed within the hollow of overhanging-arm II and actuated from shaft I9 in a well known manner. Cooperative with needle I4 in stitch formation is a looper 25 of the rotary type which is secured to one end of a transversely-extending shaft 26 journalled beneath bed plate I0. Incident to the sewing, the fabric material M being operated upon is intermittently advanced on bed plate IIJ relative to needle I4 by a feed dog 21 which is connected to a rocker 28, and reciprocated, through an arm 29, by an eccentric 30 on a longitudinally extending shaft 3l beneath said bed plate driven through connections (not shown), within the standard 20 from shaft I9. Rotary movement is imparted to looper shaft 26 from shaft 3| through a pair of miter gears 32 and 33. Opposing the feed dog 21 from above is a centrally open presser foot 35 which is pivoted at 36 to a bracket arm 31 at the bottom of the presser bar 38, the latter being spring biased as usual and constrained to up and down movement in the needle head I 2. Sewing thread T is supplied to needle I4 from a spool Sy on the top of overhanging arm II under control of the take-up indicated at 39.

To adapt a sewing machine, such as above briefly described, for the purposes of my invention, I have provided the presser foot 35 centrally of its front or advance end, with a tubular guide 40, for directing the comparatively heavy ornamenting threads T1, T2 which are to be attached to the material M relative to the stitch forming instrumentalities of the machine. It will be noted that the guide tube 40 is inclined at an acute angle toward bed plate I0, and that the passage therethrough is transversely elongate. As a consequence, the threads T1, T2 are accurately guided, side by side, downward on to bed plate I0 along a line medially of the points of penetration of the material M by the laterallyvibrated needle I4 as best shown in Fig. 4, and overlapped at longitudinal intervals by the crosswise portions only of the sewing thread T at the stitches S. During the sewing, the material M, in being advanced in the direction of the arrow in Fig. 4, is manipulated in the illustrated instance so that the ornamenting threads T1, T2 outline a pre-cut padded design piece P, and at the same time secure said piece to the base material M.

The ornamenting threads T1, T2 are supplied from spools S1, S2 which, in accordance with my invention, are supported at an elevation by an upright stand 42 positioned at a substantial distance from the sewing machine, upon the work table 43 whereon the machine is sustained. As

shown, sta-nd 42 has a base 45 wherein is anchored a rod 46 of Stout wire the upper end portion 46a of which is bent forwardly at an angle toward the machine. Adjustably secured to the inciined portion 48a of rod 46 by a screw 41, is a U-shaped member 48 whereof the extremities 48a and 48h serve, with said inclined portion 46a, as axes by which spools S1 and S2 containing supplies,ofmtheornamenting threads are supported for frefe rtationftopermit withdrawal of said threads'ffieely from them laterally. While I have shown spools S1 and S2 as impaled respectively, on stem 46 and on extremity 48a of cross arm 48, a third spool may be used on extremity48b`` if desired and its thread directed to the sewing.

For the'bz'ette` control of the ornamenting threads enrout t'o the machine, I have shown an auxiliaryguide 49 which is secured to the sewing heads'lZ and which has an angularly'benty triapertured end 'f'f49' disposedin pioiiirxfiityY to guide tube 4Jll""on pr e"ss`e foot 35`a`t'a slight elevation above tli'la'tt'r. i I y l ein.` thenbregoing,v it will befseen that Ihave provided a' 'sinrfr'leA and inexpensive attachment whereby l ornamenting threads are controlled ef rute toh'the stitch-forming instrumentali se off thsewmgimaane and diventasse bi* 'ma Sf as t0 b e' attached t0 the. basel maar r'l M' adfovelrlapped ai spaced: intervals; I Ofn. gitudially byf the cross portionsv only or vthe sew: threaduwith the' stitching otherwise sub- 1 repealed I-Iaving thus described my invention, I claim: 1"; In a machine having` a bedkplate,` and ""'therefor'an overhanging arm with a terhead 4for supporting an endwise-re'cipro; laterally-vibrated sewing thread-carrying le',- a' coop.erating'` thread-carrying louper, 'a gelement for intermittently advancing c 'laterally ofthebed plate beneathl the arm, and a'pre'sser foot to cooperate with the feeding element, the combination of a stand mounted on the table substantially in line with the arm of the machine and beyond the head thereof, said stand being in the form of a post with its distal end portion inclined toward the needle head of the machine; a bracket axed to the distal end portion of the post and provided with pins at a corresponding inclination upon which individual spools for, plural ornamenting Athreads 1are imp'aled; and a straight transifrlerselyilafttened guide tube on the presser foot, said tube being tapered and downwardly sloped toward the bed plate with itsularge end uppermost to receive the ornamenting""tlieads in straight lines from the supply spools substantially at right angles to the axes of said" spools', andv to 'converge said threads into directlaterallyr'abutting relation for delivery in a horizontal path side by side medially of the pointsof penetration of the fabric by the needle so as' to be overlapped at 1ongitudinallyspaced intervalsby tl'iswing thread. u n 2, The' inventioriracord'ing tof'c im'lr'u including" a pendent :ringerA afll 'ed kt the vne head of the vmachine aridhaving'.at` itsfdf end; spaced gpideeyeror raitainingjtae ,orinenting" threadsdeniteiy separatedat' a" tance slightly in advance ofvv the' tubular guide on the presser foot.
