SEWING MACHINE Application filed April 14, 1930. Serial No. 444,215.

This invention relates to a sewing machine for tufted rugs, bedspreads and the like, the general object of the invention being to provide means for imparting a combined re- 5 ciprocatory and oscillatory motion to the tufting' needle so that the point of the needle moves in an elliptical path and loops the thread over the pointed member of the machine.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which 1- a Figure 1 is a vertical sectional view through part of the machine, showing the needle bar and the parts associated therewith 2 in edge view. L

Figure 2 is a section on line 22 of Figure 1. Y

In these views," the numerall indicates a motor driven shaft supported by the hangers 2 which are fastened at their upper ends to the top .part of the sewing machine frame,

and the numeral 3 indicates a disk fastened to the shaft and-carrying a crank pin 4 to which the lower end of the needle'bar 5 is guide 6 which is formed with a lateral ear 7 at its upper end which is pivoted to a pin 8 carriedby one of the hangers 2. The pin 8 is adjustable .verticallyzin a slot S'provided in the hanger-2 and held in its given position by'nuts 8 Thus the needle bar is given a combined reciprocatory and oscillatory movement by the rotation of the shaft 1, whereby the needle 9 at the upper end of the bar is moved in an elliptical path as shown a by the dotted lines 10 in Figure 2. This movement of the needle controls the feed of the material through the machine and causes the needle to make the loop over the point 11. The feeder bars 12 are reciprocated' tical path during the reciprocation of the pivoted. The needle bar passes through a through the links 13 and the cam 14 on the shaft 15 which is journaled under the top of the machine and which is driven from the shaft 1 in any suitable manner. The knife is shown at 16 and ortion of the operating means thereof at 1 It isthought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What we claim is I c A sewing machine attachment including a vertical hanger depending from the machine, a power shaft journaled in the hanger and havlng a crank pin, a needle supporting bar having. one end journaled on the pin, a needle supported by-the upperend of the bar,

a sleeve slidably receiving the bar adjacent its upper end, said hanger having .a vertical slot, a transversely disposed pivot pin having one end adjustable in said slot, means for holding the pin fixed relatively to the hanger, and an ear formed on one end of the sleeve and receiving said pivot pin, whereby said bar and needle are caused to move in an ellipbar.

In testimony whereof we affix our signatures.

CLAUD E. SPIVEY. JOHN C. RODEN.
