This invention relates, generally, to improvements insewing machines; and the same I hasreferen'ce', more particularly, to a novel construction of machine especially adapted 7 +5 for stitching hook-fastener tape to garments and thelike. The'invention has: for its principal object to provide a novel hook-tape guiding and control means which is adapted to keep the hook- ".l!) tape perfectly aligned to the sewingineedle or needles as it movesunder theimpulsion of the normal feeddevices ofthe stitching mechanism pastthe sewing point, tothe end that close and accurate placing of the line of 7 11 stitches relative to the hooks of the tapemay be attained without distorting or displacing strains being imposedon the tape at the sewingpoint, and sothat rapid stitching may be carried on without danger.v of the I metallic hooks of the tape coming in-contact'with the sewing needle or needles with consequent risk of either breaking the needle or damaging the hook fasteners; I j I :Other objects'of this invention, not at this 3 time more particularly enumerated, will be 7 clearly understood from the following detaileddes'cription -of the same. I This invention is clearly illustrated inthe accompanying drawings, in which Fig. 1 is a front sideelevationof a sewing 1 machine for sewing hook-tape accordingvto this invention; Fig. 2-is an;.end elevation of 'thesamein part section ;.Fig. 3 is afragmentary sectional view, taken online33 in Fig.

scale; Fig. 5 .is a side'elevation ofa modified formof hook-tape guiding and control roller and Fig. 6 isa sectional viewof the latter,
' "taken on line66 in Figz5. Y
Similar characters of reference are employed .in .all of the 'hereinabove described views, to indicate corresponding parts.
4 7 Referring to said drawings,the reference character 10 indicates theibed-plate of the sewinginachine, upon which ismounted the arm 11', at the free endof which isarranged the usual reciprocating needle, bar 12 and spring ftensioned presser"foot;13,the same be- 1928 Serial No. 282,113.
ing; actuated from the main shaft 14, which extends through the armll in the usual way. Connected with the bed-plate 10, so as to lie beneath the sewing point of the machine and thus extend beneath the presser foot 13 isa throat plate 15. Said throat plate 15 is providcd with elongated laterally spaced open- 7 ings 16 beneath the presser foot 13. Cooperating with said presser foot 13 is the feed-dog 17 which is provided with laterally spaced serrated jaws 18 which extend upwardly through the openings 16 of the throat plate 15 so as to operatively engage and feed the work passing the sewing point intermediate the presser foot and throat plate. Said feeddog jaws 18 are provided with perforations 19 through which the needles 12" of the sews ing mechanism may extend on their descending movement. Preferably the needle bar arrangement is of the oscillating or rocking type, whereby when the needles enter the feed dog jaws the same will swing forward synchronously with the forward work feeding movement of the. feed dog. I'have illustrated in the drawings'a two-needle type sewing 7.5 mechanism, and the throat plate is provided with a longitudinal clearance channel 20 extending beneath the presser foot 13 and intermediate the jaws of thefeed dog 17, the same being of sufficient depth to provide a clearance space through which the hooks h of thetape 25 may pass as the tape (hook-side down),together with the garment body to which it is to be stitched, rides over the surface of the throat plate and between the presser foot and feed-dog jaws during the sewing operation, thus assuring that the metallic hook-bills will not be crushed ordistorted during the sewing operation. It will be obvious that, one of the needles may be omitted, if it is desired to utilize the machine as a single needle machine. It will also be obvious, should it be desired to feed and sew the hook tape with the hook-side up, that the clearance channel 20 may be reversed in respect to the cooperative relation of throat plate and presser foot, i. e. suchchannel 20 may be omitted from the throat plate and provided in the bottom of the presser foot, such change being, to those skilled in the art,
an obvious equivalent for that above described and shown in the drawings.
The means for guiding and controlling the movement of the hook-tape tothe sewing mechanism of the machine, so that the same will travel true andstraight without distortion or such accidental displacement as might be likely to permit someportion of the metallic hooks to be engaged by the sewing needles with risk of injury to eitherthe one or the other, comprises, in oneexemplifying form, the following structure I v J ournaled in and between an upper bearing 21 (which is fixed onthema'chine arm 11') and a lower bearing 22 (mounted onthe bed plate' 10) is vertical shaft 23. This shaft 23 is driven from-the main shaft 14' of the machine'by means of an intermeshing worm 24 and worm gear25 respectively fixed on said main shaft 14 and vertical shaft '23. Mounted in bear-ings26 adjacent to said ver tical shaft 23 is a transverse shaft 27, the
same, being driven fromsaid vertical shaft by 'means of i-ntermeshing screw gears 28 and 29 respectively fixed on saidvertical and transverse shafts; Fixed onsaid bed-plate 10, so as to overhang the front side thereof, is a bearing bracket 30. Journaled in said bearing bracket is a lay shaft 31. This lay shaft 31 is driven from said transverse shaft 27 by' means of intermeshing screW-gears32 and'33 respectively fixed on said transverse and lay shafts; Fixed on the outer end of said lay shaft 31, so as to be rotated thereby is a tape guiding and control roller34, the same having an annular channel-35 in its circumferential face to accommodate the projecting parts of the metallic hookfasteners 1 carried by the tape. At its forward end said bearing bracket 30 possessesa'dependingarm 36,-and journaled on a stud 37 carried by said depending-arm is an idler guide roller 38 vertically aligned relative to said tape guiding and control roller 34 Said bearing bracket 30 is further provided with a guide plate 39 disposed intermediate the rollers 34 and 38 and in vertical plane tangent to the tape sup porting surfaces thereof, said guide plate also having a channel 40 in its face to accommodate the projecting parts of the metallic hook fasteners carried by the tape. Projecting forwardly from the lower end of said bearing bracket arm 36 is a knuckle 41, and pivotally connected thereto by a fulcrum stud 42 is an'upwardly extending bearing arm 43. Journaled in the upper end of said bearing arm 43' is a spindle 44, and fixed on the'outer end of said spindle is a gripping roller 45to'cooperate with said tape guiding and control roller 34. Said gripping roller 45 is drivenin an opposite directionto the tape guiding and control roller 34 by means of intermeshing spur gears 46 and 4? respectively fixed on said lay shaft 31 and spindle 44. The bearing arm 43 is'yieldably pressed sewing mechanism as follows inwardly totensionally press said gripping roller 45 into gripping relation to the tape passing over the tape guiding and control roller 34; and to this end suitable pressure spring means "48 is provided. The roliers 34 and 35 may be separated for the insertlon, of 1 the tape therebetween, and for this purpose the bearing arm 43 is provided, at its upper. V
end, with a nosing 49 engageable by the cam member 50 of a pivoted lever 51, so that by baris intermittently actuated in timed rela tion to the work feeding operations of the Pivoted on said bearing bracket .30 is an oscillatable lever 54the upper end of which is provided with a roller or stud 55 engagee able by an actuating cam-56 mounted on and rotated by said transversev shaft; 27, and to the'lower arm of which is pivotally connected said notch soa'sto hold said stop-bar inimov able until again released. i
In operation, the hook tape is supply reel (not shown) over the guide roller 38 and then upwardly-over the guide plate 39 to pass between the roller 34 and 45 and thence' forwardly so as to traverse the throat plate 15 tothe sewing point, at which point vit isengaged by and between the presser foot the rear end of said stop bar. Apull spring g a 1 led from a l3 a nd feed-clog 17 so as to be-ipropelled for- I ward thereby (together with the garment body which is fedthrough'the hemmer-H'to pass with the tape to thesewing :point) in such manner as to produce the desired stitching. .The rollers 34 and 35 relieve the press er foot-feed dog mechanism from the drag of;
the tape, while nevertheless keeping the'l'atter straight and accurately aligned to the sewing needles as 7 well as perfectly controlled against over or under feeding. The channels 35 of the roller 34 and 20 of thethr'oat plate 15 accommodate the projecting portions of v 75 swlngmg upwardly said lever 51 the cam the hooks of the tape'so that the latter lies .controlled, is held against side slipping or other displacement likely to prevent the accurate. placing of the stitches, or likely to carry-the metallic fasteners of the tape, in
. contact with the sewing needles; and by reason of such guiding and control it is possible in theoperation of the machine of this inventionto form the lines of stitches very close to the edges of the tape without danger of 7 running off the same, thus enabling machine I stitching to be rapidly produced along very narrow and restricted tape margins. This is possible even when applying tape to curved garment edges, due to the perfect control of the tape as it passes to the sewing point.
Referring now to Figs. 5 and 6 I have 7 shown a modified form of guiding and control roller, the use of which will permit the gripping roller v45. to 'be' dispensed with.
i This modified roller is provided on its Circumferential face with equi-spaced flattened bearing faces Ior, facets 61 to engage the tape body t, each face or facet having an indented pocket 62 to receive the projecting portion of the hook fasteners 71,. The angular relations of the faces or facets 61 together with the pockets 62 serve to grip the tape sufficiently to assure both its forward movement as well as its timed control; all of which will be understood from an inspection of the said Figs.
5 and 6 of the drawings. v

well'as in thedetails of the construction of the same, without departing from: the scope of this invention as described in the foregoing specifications, and as defined in theappended claims. Hence, I do not limit this invention to the-exact arrangements and combinations of the various devices and parts as set forth in the foregoing specification, 'nor do I confine myself to the exact details of the construction of said parts as illustrated in the accom- Jpanying drawings.
