Definitions

  • the invention relates to new and useful improvements in cup feed machines, and more particularly to the feeding mechanism therefor.
  • An object of the invention is to provide a feeding mechanism for operating intermittently the inner and outer feed cups which include devices whereby the feed stroke imparted to the feed cups may be independently adjustech and when so adjusted, positively held in. the respective set adjusted positions.
  • a further object of the invention is to provide a feeding mechanism for the feed cups. wherein the strokes of the cupma'y be simultaneously adjusted by. devices, located within the casing of: the machine and through the aid of means which extends to theoutside of the casing.
  • Fig. 2 is a view in transverse section through the casing and showing the; means for adjusting the feed strokes ofgthe cups;v
  • Fig; 3 is aydetail"perspective view'offone of. the arms for, actuating-- the fee'dingdevices for one of the feed cups, and:
  • Fig. 1 is a detailin section showing the means accessibledfrom the outside of the casing for, simultaneously- ,adjusting the stroke;ofithefeedcups.
  • the invention is shown as applied to a feedcupanachine of the type disclosed in Patent N0.- 1,246,302, granted, to James R. Moflatt,November lEw, 1917;
  • Said machine includes acasingl in which is mounted a main shaft 2. Also reciprocating. in the casing is a needle bamcarrying a. needle 3.
  • looper 4 Cooperating with th e needle 3 is a looper 4,
  • the arm 18 isin turn mounted on, a vertical shaft 19 carried by bearings 20,- 20 on the outer face of the casing.
  • the otherfeed .Cu'p G iscarried by ashaft mounted in a sleeve bearing 21, which sleeve bearing-is formed-as a partofthe bracket: pivoted at 22, so that. said, sleeve bearing may. be moved to separate-the feed cups whenidesired; This is accomplished means; of a. lever 23, a. spring: 24:operatingtohormally hold the feed cups pressed yieldinglvtoward'i each: other. c
  • the clutch plate. 25 carries a'ballstu'd 281 Alinle 29 engages said do all stud at one end and at its other endengages a ballist-ud SOCar-iiedwbven arm 31 mounted on' the upper end' ofathe shaft of-ob'long openings 32.
  • the shank of: the ballstud 30 1s 1nsertcd iii-these openings and may be shifted ifrom one openin-gto' another I forvarying, the stroke of the clutch plate.
  • the arm. 18" is likewise provided with".
  • either feed cup may be adjusted without varying the stroke. of the other.
  • either feed cup may be caused to rotate faster than the other.
  • One feed cup bears on the inner face of the fabric sections being stitched and the outer feed cup bears on the other face.
  • the fabric sections may be controlled as de sired.
  • the shaft 19 is oscillated by means of an eccentric strap 34 which cooperates with an eccentric 35 on the main shaft 2.
  • the eccentric strap 34 is connected at its outer end to a ball stud 35 (see Fig. 4) on the end of a rod 36.
  • This rod 36 passes through a sleeve 37 clamped on the shaft 19.
  • Said rod is slabbed on one side thereof so as to prevent the same from turning in the bracket sleeve 37.
  • Set screws 38 clamp this rod in its adjusted positions in thebracket sleeve. of a split collar mounted on the shaft 19 and is secured thereto by a clamping screw 39.
  • an arm 40 Also mounted on the bracket sleeve 37 is an arm 40. Said arm is secured to the The arm projects outwardly from the bracket sleeve and is bent downwardly at 42.
  • the adjusting screw 43 is mounted in this arm 40 and is threaded into an end ofthe rod 36. Said adjusting screw has a collar 44 secured thereto and the bent portion 42 of the arm lies between the head of the adjusting screw
  • said rod When the set screws 38 have been released from their gripping hold on the rod 36, said rod may be shifted endwise of the bracket sleeve by turning the screw 43. This shifting of the rod 36 endwise varies the distance of the ball stud 35 from the center of the shaft 19 and thus varies the extent of oscillation imparted to the shaft 19 by means of the eccentric strap 34.
  • eccentric 35 and'the eccentric strap 34 are located within the casing, and the strap is connected directly to an armcarried by the shaft l9, which likewise projects inwardly into the casing.
  • the screw 43 for adjusting the rod 36 carrying the ball stud to which the eccentric strap 34 is connected is accessible from the outside of the casing.
  • the bracket sleeve is in the form few parts, and these parts .are located in the main within the casing of the machine, and at the same time, they may be adjusted by means readily accessible from outside of the Furthermore, it will be 'noted that the adjustment is of a positive character, that is, the rod 36 isshifted by means of a screw so that a very slight turning of the screw will bring about a limited change in the throw of the feed cups. Not only does the screw aid in holding the. parts in set ad-c justed position, but-the parts may be locked in their adjusted position by the set screws 38. Y V
