inname.
To all 'whom z't may concern.:
Be it known that we,;'.IAMns R. MOFFATT and RALPH S. KELso, citizens of the United States, residing at Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Sewing-Machines, of which the following is a description, reference being had to the accompanying drawing and -to the letters land figures of reference marked thereon.
is necessarily very much restricted in which the loopers must operate to get the lforward and back and sidewise movements, and they must be made to swing within the limits of a very restricted area, since the bed plate must be of as small diameter as possible.
The object of the invention, therefore, is to so support the loopers that they shall have the full swing necessary to properly concatenate with the needles to form the independent rows of stitches1 but yet at the same time, the movements may take place in a bed plate of minimum diameter.
The invention, therefore, consists in the matters hereinafter described and referred to in the appended claim.
'Ihe invention is illustrated in rtheaccompanying drawings, in which- Figure 1 is 'a side elevation of a sewing machine embodying our invention, partly in section and parts being broken away; Figs. 2, 3, 4 and 5 are sectional end views, showing theneedles and loopers in dierent relative positions during their travel; Fig. 6 is a detail toppl-an view of the loopers in full and dotted positions, the needles being shown in section; Fig. 7 is a detail view of the needle guard; Fig. 8 is a detail perspec. tive of the end of the looper-supportmg shaft; and Figs. 9 and 10 plan and sectional views respectively illustratlng the Specification of Letters Patent. i

work done on the machine; Fig. l0 being a section on line 10-10 of Fig. 9. In 'these drawings, the machine as a whole is of the well known type known as the Union Special side wheel cylinder machine, and having the cylindrical bed plate l, the presser foot 2, the needle bar 3, the looper shaft 4, the feed dog 5 reciprocating longi tudinally of the bed plate, the needles 6, loopers 7 and folder 8.
'Ihe needles 6 are herein shown as three in number, `set oblique to one another respecting the line of feed, the left hand one looking toward the machine being in the rear.` It will be understood, however, that the reverse arrangement may be used.
The forward end of the looper shaft 4. has an offset flattened projection 9, having three openings l0 in line, in which the Shanks of the loopers are set, the loopers being of different lengths, so that their beaks set obliquely to one another respecting the line of feed, corresponding to the' set of the needles.
11 represents the needle guard having the three beveled projections for guiding and preventing deflection of the needles.
By having the eccentric oset 9, it is possible to have loopers of dierent lengths with their Shanks all set in line, and to get the full throw of each looper necessary to take its needle loop and perform its other movements, and still have those movements take place in the space of a cylindrical bed plate of small size, and yet without any danger of the needles in their lowest position striking the looper support.
The present construction lends itself readily tothe formation of a plurality of independent rows of 'stitches on a small cy- ;1 man rains naaien nnnipn. f
lindrical bed plate, without the necessity of A having a wide head on the looper shaftto accommodate a series'of obliquely set holes `for the looper Shanks, and without the neneedle, the other loopers coperating with loopers are shown in full lines as having,l
their@ needles similarly. In` Fig. 6, the
completed their (forward movement, and in dotted lines as having moved over in their needle-avoiding movement and coming back. In `Figs. 4 and 5, they are going through their backward movements, and the needles are coming down.
lHaving thus described our invention, what we claim as new and desire to secure by Letters Patent, is J The combination with a cylindrical work support, of a needle bar, a plurality of needlescarried by said needle bar and arranged in .line oblique to the line of feed, a looper supporting shaft arranged with its axis horizontal and in a vertical plane containing the needle bar, said shaft having an JAMES a.
