"This invention relates to new and useful improvements in attachments for sewing machines, and the object of the invention is to provide a simple and efiieient means for supporting the spools of cotton so that a bobbin for the shuttle may be easily filled with thread while operatingthe needle bar for sewing purposes.

Another object is to provide anattachment of the class stated which maybe attached to the machine permanently so that itwill be in position for use when required without dismantling or disconnecting any In my invention, I provide an attachment which is mounted on the ordinary spool support secureolto the head of the sewing tachment.

machine. The attachment is provided with .an outwardly projecting guide for leading the thread towards the bobbin winder mounted as a general rule on the face of said head. l i

In the drawing which illustrates one form of my invention+- Figure 1 1s a perspective view ofa machine head with the improved attachment mounted thereon.

' F1gure2 1s a perspective holder 19 is the attachment 27, shown in detail in Figure 2. The spool'hold'er comprises a vertically disposed tubular member 18 which fits over the holder 19 and is of such a length that it will support two spools of

cotton

20 and 21, one above the other. The thread from one of said spools'passes',

over suitable guides to the needle 22 secured to the needle bar, while the thread 23 from the other spool passes to the bobbin 24 mounted between the spring catches 25 of the bobbin winder, which is driven through the medium of the belt 17 and the'pulley26.

Projecting outwardly from the tubular member 27 is the arm 28, which first bent up view of the at-- wardly parallel .to the holder then the form of a U' to form a guide for the thread-23. t o

. The device is very simple in operation and v v provides a simple means for filling the bobbinon the bobbin wind-er, withoutdismant- ,lingthe arrangementof threads on themachine. To wind a bobbin on the bobbin" winder, thethread 23 is taken from the spool the hooked or U portion 30 of the arm 28,

21 and passed'through the space 31 and into and from thence to the bobbin mounted be to contact with-the driving belt which rotates' the .b'obbin25 through the medium of the pulley Zii. The rotating bobbin 25 pulls the thread 23 from thebobbin 21, said thread passing through the space 31 and also through the space between thelegs of the U 'tweenthe spring catches 25. The bobbin winding mechanismv is then brought forward portion, and also downover the lower part of said ,U portion. 1 The guide is rotatably V mounted-on the usual bobbin holder so that the arm may be moved; to accommodate the winding actionof the thread on the bobbin 25. The attachment may be permanently mounted on the machineso that the bobbin 25 may be filled'with thread during the op eration of sewing and without interfering with the sewing mechanism or threads. (The U-shaped guide prevents; the thread from 7 becoming disengaged from the attachment I and'the arm is preferably made of round bar to prevent the threadfrom breaking while passing through the parts of the attachment. Having thus described my invention, what Iclaim is:" r V .-.1. An attachment for sewing machines comprising, a tubular member'ada'pted to be slidably mounted on the bobbin holder and made long enough to .form a support for a plurality of bobbinsof thread, and an arm secured to .and extending outwardly from said tubular member, thefen-d of said arm beingbent to form a guide for thread from oneof said bobbins to a shuttle bobbin.

.2. An attachment for sewing machines comprising, a tubular member mounted on c the bobbinholder of the machine and adapt fed to rotatably support a plurality of, bob-" bins of thread, an arm' secured to and ex-j' tending outwardly from the tubular memher, the end of said arm being first bent-up I war'dly, and terminating in the formlof a U to form a guide for thread being wound from of the machine.

- one Otthe said bobbins to a shuttle bebbin mounted ,on the thread winding mechanism 3. A11 attachment for sewing machines comprlslng, a tubular member adapted to supporta plurality of bobbins of thread, an arm secured to the bottom and extending outwardly atright angles te the tubular o enend of the U facing in the same direction as the top of thje'tubular member.

In Witness whereof; I have hereunto set my hand; 7
