Definitions
- This invention relates to improvements in feeding mechanisms for sewing machines, and has for its object to provide means for uniformly advancing materials of varying texture and thickness to the action of the stitch-foirming meclninism, and is internally adapted for use in connectionnvith attaching eollarettes or elastic bindings to knitted fabrics.
- the pres: ent construction etl'cct is the desired result by providing a feeding mechanism which eomprises a single teed-dog having multiple feeding surtaces, in connection with multi ple cloth-prcssers which are adjustably secured relatively to each other, thus providing means whereby the thicker or seamed portions of the material will be advanced in a manner common to sewing machines gcir orally, while the thinner or body portions will be acted upon by the adjustably-sccured cloth-pressers which, in the present instance, are constructed to yield to the action of the feed-dog ii'ulependently ol their vertical movements with the presscnbar, to lacilitate the feeding ot substantially heavily ribbed knitted goods.
- Figure l is a view in perspective ot the improved mechanism, together with an (alge-tolding guide and a portion of the r'ltilll or bed plate of the sowing machine.
- l igs. 2 and 'lare perspcc- I tivc views of the cloth--pressers, throat;-plat.e,
- Fig. is a pcrl Specification of Letters Patent.
- the teed-dog 16 comprising the integrally-formed feed-points or feeding surfaces 17, 18, it) and 20, is mounted and operated in a manner common to sewing machines employing four-motion feeding mechanisms.
- the throat-plate 21 is secured in the usual manner to the plate 1 and is provided with suitable openings for accommodating the needle and ieeddog in their actnations. Said throat-plate is also provided with a raised portion, the upper surface of which occupies a plane substantially in line with the median horizontal plane of the delivery end 22 of the edge-folding guide 3.
- the thicker or seam portion 23 of the material is fed beneath the cloth-presser 8 by the action of the feed-points l8 and 19, the two-ply portion of the binding material 24 is advanced under the spring clothprcsscr l-l by the action of the 'leedpoint 20, and the main or body portion of the material is advanced by the coaction ot' the spring cloth-presser l3 and feed-point 17.
- an independent feed control is provided for each ditl'crent thickness of material.
- A. [ceding mechanism for sewing machines comprising a throat-plate, a teed-dog, a presscr-bar, and a plurality ot cloth-presscrs carried by said prosser-bar, said clothpressers being relatively adjustable to normally hold their ell'ective surt'aces in different horizontal planes, the central ol' said iclot'h-pressers comprising a rigid clcment,'
- the central of said cloth-pressers comprising a rigid element of substantially the combined width of the cloth-pressers arranged on opposite sidesof said central clothresser, said oppositely arranged cloth-pressers being flexible to yield vertically for the purpose described.
- ' chines comprising a throat-plate, a feeddog, a presser-bar, a presser-bar bracket and a plurality of cloth-pressers carried. by said bracket, said'cloth-pressers being relatively adjustable to normally hold their effective surfaces in difl'erent horizontal planes, the
- central of said cloth-pressers comprising a rigid element and the cloth-pressersmrranged on opposite sides of said central clothresser beingflexible to yield VBI" tically for the purpose described.
- a feeding mechanism for sewing machines comprising a throat-plate having its upper surface stepped to better accommodate the feeding of superposed plies from the delivery end of a folding guide to the able to normally, hold their efiective surfaces in different horizontal planes, the central of said cloth-pressers comprising a rigid element and the cloth-pressers arranged on opposite sides of said central cloth-presser being flexible to yield vertically for the purpose described.
