- This invention relatestogauges for sewing machines and has for itsobject to provide an adjustable gauge which is more simple in construction and efficient in use than those heretofore proposed.

With these and other. objectsin view the invention consists-in the novel details of constructionand combinations of parts as will be more fully hereinafter disclosed and particu-v 1O larly pointedout in the claims.

Referring to the accompanying drawings forming a part of this specification in which likeinumerals designate like parts in allthe views: 1 .1. 1 'Q F'g. 1 is apers ective viewlillustratingthe invention as "app ied to a sewing machine;

17, 1927, and entitled Adjustable gauges for "sewing-machines. One of the objects of this vinvention'is to provide a construction the parts of which arereadily turned out ofoperative ipositions when ordinary sewing is tobe done by themachine thus giving more spac e'forthe work being sewed 1 p -Ano her object of this invention is to provide. a construction'whichis lessgcumbersome, has fewer parts, and permits greater adjust- I ability with more ease than'those heretofore proposed," while "atthe same time maintaining l inherent strength and necessary rigidity to ducing the weight of the 'niachine. I 1 indicates the throat'plate, 2fthefoot, 3 the needle; and ltheneedle 'baiiusuallyfound in, i sewing machines ofthis type;- while 5 is 'a gage the teeth of'a pinion 23.journalledin accomplish the results desired, as well as relever adapted tooscillate theneedle 3Ifrom sideto side to formjdiagonal or zigzag stitching, said lever having a depending portion 6 connected as througha link 7 with the sliding rod 8 disposed below and in substantially the same vertical plane with the main driving shaft 9 of the machine. 10 is the thread looper carried in prolongation of and at the end of the main driving shaft 9 and adapted to rotate beneath the throat plate 1 which is secured to the frame 11 of the sewing machine as by the screw 12.

7 By disposing the sliding rod 8 in substantially the same vertical plane with the main drive. shaft 9, the entire gaugemechanism canbe mounted closer to the needle 3 than those heretofore proposed, and particularly that disclosed in my co-pending application.

7 The gauge mechanism comprises the vere tically disposed supporting plate 15, secured as by the screws 16 to the bed plate of the machine, which is provided with the track 17 upon which slides the gauge unit generally indicated by'the numeral 20. The unit 20 has a base portion 21 on the bottom edge of which are cut rack teeth 22 adapted to enthe frame of the sewing machine and provided with a knob 24 integral with the pinion for turning the same and thus'causing the unit as a whole to slide onits track from left to right. i p i The baseportion 21 is provided with a slotway 25 extending horizontally and through'which freely passes a stud 26rigidly threaded into thesupporting'plate 15.

This stud 26'carries a bracket member 27 55 having an out-turned end serving as a journal'forone end of a rod 28 the other end of which has rigidlyformed therewith a fixed member 29 serving as an edge guide having a-lugBOJadapted torest in an aperture 31 0 formed'thereforin the throat plate 1. One

side/of the edge guide 29 is curved to conform to the surface ofthethro'at' platefand the opposite side or edge is provided with'a fin ger piece32bywhi'ch said edge guide may readily be turned downwardly: about the centerof the'rod 28 as anaxisas shown in Fig.2. out of the Way of' any material upon which the' us'ual stitching is desired. "The V 33against the-fiat sides of which the end 34 of a spring contacts to hold the edge guide 29 in either operative or inoperative position, the other end of said spring being secured about the stud 26. p The gaugeunit has an outstanding end portion or rib constituting the braid guide 7 i which is adapted to closely and contactc p 7 V that no part of-the braid guide will be above 4 the horizontalplane. of. the top of the throat plate and 1nthe way,ofmater1al bemgsewed Thelower section of the braid guide is aper- 1 tured to permit the edge guide rod28 to pass therethroughand be supported therebyy said aperture providing a close. sliding. fit with ing of the gauge unit as aowhole on its sup--v cportingplate -15; 'r

At the u aportion of the base member 21 ,.-and near; theright. hand end thereof there is provided an ex ending bracket 1 provided'witha slot; 51'to confiningly, receive a knurlednut 52 threaded: on the rod 53 eX= tending horizontally through said bracket 3 50 to and throughflanother bracket :5 1' dismember 21.
