The opposite end of the case has a of the color is an exceedingly simple operation guide member 23 through which the thread is that can be performed expeditiously by the op passed for subsequent threading through the erator. The machine obviates the necessity of sewing machine. using a multiplicity of spools of differently Having recounted the dyeing machine to colored 'thread particularly where sewing opera 40 which my invention relates _the invention itself tions require change of color of the thread for a will be described in detail. The improved struc short interval. ture of the slide mechanism comprises forming In such a dyeing machine it is highly desirable the slide I5 of a flat strip of metal bent into a that the slide be constructed so as to be freely substantially U-shaped conñguration having a movable from one position to another without any 45 bight 24 to which the standard I6 is secured and tendency to bind or stick. Hence it is a major object of the invention to provide a slide mech having converging legs 25 extending downward ly with their lower >ends engaged with the re anism of improved construction having salient spective edges 26 of the slot I4 under light ten features of advantage. sion. The extremities of the said lower ends are Another object of the present invention is to 50 bent outwardly, as at 21, to ñt under the lid I2. supply a slide with a simple and efûcient indexing The bent extremities 21 are in the nature of device. ' flanges bearing against the bottom face of the A still further object is to furnish a more lid and serving to retain the slide I5 in proper serviceable dyeing machine which can be manu position over a vat with the standard I6 depend factured at low cost. 55 ing therein and the reaches of the thread con 4 ule over a vat as the slide is moved along the tacting the mouth of the vat so as to Wipe off ex slot and this will properly index the slide. The advantages and utility of the invention will be manifest from the preceding description and it will be evident any number of vats may be cess dye. The slide is made of a material of a resilient nature and the legs 25 frictionally eœage the edges of the slot I4 with suñicient firmness to assure of its being retained in any position in which it may be set. The material of the lid at the edges» ofv thev slot is desirably upturned to form narrow flanges as at 28 which present a, smooth slide surface for contact with the lower used either in one or more rows. What We claim is: In a dyeing machine of the class described, comprising a case for containing a lrow of vats `and having a hinged cover includingl material Y guide means projecting through an elongated ends of the legs 25, Due to the convergency of ` the legs the flanges thereof form guide grooves . slot in said cover for movement from one to an Íotherof said vats, the improvement including for the slide. To shift the slide along the slot` in changing from one color to another it is merely'necessary to grasp it by hand and squeeze lthey legs .so thatk , Y slide means for supporting said material guide meanasaid slide means including a substantially . U-shaped member of springy material having converging legsr flanged at their distal ends for interñtting engagement with side edges of said it may move freely to a new position; it> being understood that the lid is ñl‘st swung upwardly ' so that the vats will nothinterfere with the travel of Vthe standard i6. vItis most important. thatìthè standard be p0 sitioned exactly atnthe centre of a vat in order that the thread _may _have‘proper wiping contact with the top edge _portion thereof. `_For this pur pose an indexing device may lirel employed. Such an indexing device may comprise the `*provision of an aperture 2*»9 in one of' the legs 25> of the slide and rounded nodules 3i] formed on the cdr responding edge _of the slot I4. The nodules are located at intervals. alongside the sl’ot’ according to the spacing offtheßvats andmay be formed by struçlç up >parts ofthe li'dî material. By this ar rangement theY aperture 29 vvillv engage a nod slot under outward tension, said material guide means being attached to the bight portion of said U-shaped member' and having a material guid ing element extendingl` between said legs and pro-> truding therefrom for projecting into one 'or an other òf said vatsl according' to the' position ofthe slide means, and an indexing device for said slide 25 means comprising’ nodules on Said cover of the case spaced at intervals along one edge o'i the' slot therein for engaging in a locating aperture 20 provided in the adjacent'leg of said~ U-shaped 30 member. p ._ A FREDERICK CARTER'.
