CUP-FEED MACHINE.

Application filed May 29, 1924. Serial No. 716,745.

The invention relates o new and useful improvements in ovcrseaming machines, and more particularly to an overseammg machine of the type `known as the cup feed machine, wherein the material is supported by rotating cups or feed wheels, while the material is held in a vertical position and the overseaming stitches are :formed about the edge of the material.

1n a machine of this type, it is very essen vtial that the feed cups shall meet at a point directly underneath the needle so that the fabricA will be clamped in line with the point where the needle enters. it is also essential that the top edges of the feed cups shall be in substantially the same plane, and that the vertical faces shall make Contact throughout their entire extent and particularly at the Aupper' edges. ln order to accomplish this, the object of the present invention 1s to provide a support for the outer fe l cup, which support is capable of being adj ted sothaei the feed cup may be shifted in a. direction. parallel with the line of feed, likewise in a direction at right angles to the line of feed, and also vertically, so as to insure the proiier placing of the feed cups relative to each other. 1

ln the drawings which show by way of illustration one embodiment of the invention- Figure 1 is a side view ofthe machine em- Y bodying my improvements;

Fig. 2 is 'a plan view of the same;

Fig. 3 is a sectional view on the line 3 3 of Fig. 1;

Fig. d is a sectional view on the line 4 4: of Fig. 1, and

Fig. 5 is a perspective view ofthe support ing plate for the bracket which carries the outer feed cup. j

The invention is directed broadly to a cup feed machine and the particular manner in which theouter feed cup is mounted. 1t includes devices whereby the feed cup supporting bracket may be shifted laterally in a direction parallel with the line of feed, and also devices whereby said bracket may be shifted laterally ina direction at rightangles to the line of feed, and again it includes devices whereby the bracket may be tilted in a vertical planefor raising and lowering the outer feed cup. rlheseV adjustments are accomplished by mounting,` the bracket which supports the outer feed cup on a plate which is rigidly attached to thexframe of the machine, said as to make an overedge stitch.

bracket being pivoted to the plate and capable of an angular adjustment in a vertical plane, which accomplishes the raising and lowering of the outer feed cup. rilhe plate is in turn adjustable cndwise in a horizontal direction, and this accomplishes an adjustment of the outer feed cup toward and from the inner feed cup, or in a direction at right angles to theline of feed. The supporting sleeve for the outer feed cup is mounted ona shaft which is capable of being swung to move the euterfeed cup away from the inner feed cup, and this shaft is so mounted that 'it may be moved endwise in its supporting` bearings, and this accomplishes the adjustmeut of the feed cup in a direction parallel with the line of feed.

'lhe machine to which my invention is applied is Aof the type shown and described in the application of James lt. Moffatt, tiled December 7, 1923, Serial No. 679,150, and it is not thought necessary to describe in detail the machine.

rEhe machine consists of a main frame 1in which is mounted a reciprocating needle bar 2 carrying a needle 3. Cooperating with this needle is a looper which is so operated The fabrics to be stitched are clan'ipedv together between two feed cups or feed wheels 4 and 5. The feed wheel 4 is mounted on a shaft carried in a sleeve bracket 6, while the feed wheel 5 Vis mounted on a shaft which in turn is journaled in a sleeve bracket 7. l' lhe'shaft carrying the feed wheel 5 is operated by means of a link 8 through a suitable clutch feed 9. The vinner feed vneel 4C is operated in turn from this saine Vshaft means of a clutch feed connected to the arm 10. rlhe link 8 is connected to the vertical shaft 11 which likewise carries the arm 10. This shaft 11 is operated by suitable mechanism from the main shaft of the machine. rlhe sleeve bracket 7 is provided with a projecting arm 12 which terminates in a sleeve 13, and Ythis sleeve is clamped to a shaft 1li by means of set screws 15, 15. rihe shaft 14 is mounted in suitable spaced

bearings

16, 16 carried by a bracket 17. The bracket 17 is secured to a supporting plate 18 by a pivot dowel 19.` This supporting plate 18 is provided with elongated openings 20 through which screws 2 1, 21 pass for securing the plate to the frame 1 of the machine.

rlhe bracket 1'? is Alikewise provided with i through these openings 22. will readily be seen that by loosening the screws 21, tie supportingl plate 18 and the bracket 17 carried thereby'may be moved endwise or in a horizontal direction., and this adjustment of two feed cups at the point where said feed cups make contact.

The bracket 1'4" is secured to the plate 18 by means of a screw 23 which passes through a slot 2d in the bracket 17. This slot is elongated and curves about the dowel pinA 19 as a center. By loosening the screw 23, the bracket 1t? can be raised or lowered, and this will raise or lower the shaft it which in turn will raise or lower the bracket 7 carr une the outer feed cup. The

plate 18 is set in a recess in the frame 1 and thisvprevents the plate 'trein slA 'ing up or down', but permits'endwise adj ustment of the saine when the screws 21 are loosened.

The shaft 1d is held from endwise

movement inthe bearings

16, 16 by means of a thrust collar 25 and an arm 26. The arm 26 is secured to the end of the shaft by a screw 27, and said arm abuts aja'ainst the outer face of the outer Sleeve 16. rlfhe thrust collar secured to the shaft by means of set screw 28 and bears against the inner face of lthis outer bearing` 16. fly loosening` rthe thrust collar and the arm 26, the shaft or hinge pin 14 may be moved endwise, and thus the bracket 7 carrying the outer feed cup shifted laterally so that the outer feed cup is moved Vin a'direction parallel with the line of feed.

From the above description, it will be apparent that l have provided a support for the outer feed cup, which permits three adjustments of said cup. lt can be raised or I lowered relative to the inner cup; it can be uioved laterally in a directionparallel with the line of feed,v and thus the point of contact 'between the cu s n'ooerl positioned. rela tive to the needle; it can be moved in a direction at right angles to the line of feed, and thus proper Contact between the two feed cups insured. Y

1t is obvious that minor changes in the details of construction and the arrangement of the parts may be made without departing from the spirit of the invention set forth in the appended claims.
