SPECIFICATION'frming part of Letters Patent No. 700,167, dated May 20, 1902.
Appiifion filed me 13, 1899.
To all whom t may coacryc:
Be it known that we, JAMES BOWEY and GEORGE 'Rocktlrnmsubjects of the Queen of Great Britain and Ireland, and residents of Sunderland, in the county of Durham, England, have invented a certain new and useful Device for Preventing the Entanglement and Breakage of Thread at the Bobbin-Holders of Sewing-Machines, 4(for which we have applied for patents in Great YBritain under No..
24,026, dated November 15, 1898, and in l(lermany undereKaffenbuch No. 1,519, dated April 12, 1899,),of which the following is a specificati'on.'
This invention relates to adevice-for preventing the entanglement and breakage of thread at the'bobbinrholders of sewing-machines.
Under certain conditions when the thread isunwinding the natural tendency ofthe coils on the bobbin is to become slack, andaccording to the prevalent practice of mounting the bobbin it frequently happens that these loose coils slip over the end of the bobbin, whereupon theyget entangled around the bobbinholder or supporting-spindle ittedupon the machine-arm, and eventually the thread is broken, with the accompanying inconvenience. To Obviate the aforementioned hability, it has been proposed to fix the bobbin to a disk tted to revolve around the bobbinholder or supporting-spindle and made of such a` size as to receive and retain any coils detachedfrom the bobbin. However, to procure effectiveness this arrangement necessitates the disk being made considerably larger in diameter than the bobbin, whereby clumsi ness and incompactness at once arise and ren-v der its use impracticable.
The object of our invention is to avoid the defects of the said arrangement; and to this end we iix the bobbin to a disk adapted to be revoluble aroundA the bobbin-holder or supporting-spindle and bear upon another disk that is secured tothe holder or spindle and furnished with ashield orguard, the arrangement being such that theV necessity for a device of undue dimensions is obviated, while any coils detached from the bobbon are received and retained by the combined disks,

whereby they are effectually hindered from fouling and breaking.
We will fully'describe our inventlon with the aid of Figure 1 is a general elevation lrepresentthe accompanyingdrawings, whereingour `device with the parts assembled ready I for use. Fig. 2 is a central vertical section f of same with the bobbin displaced. f Figs.Y 3 and 4 are plans of details.
A is a disk of any suitable material, brass'` or aluminium by preference, for receiving and holdingthe bobbin B centrally and so that it may revolve therewith. The-'surface of this disk may be dished` or recessed, flat or corrugated, and it is perforated centrally to permit the passage of the ordinary bobbinholder or vspindle C, around whichitrevolves as the thread is unwound fromthe bobbin B during the voperation of the machine, the per.- foration being somewhat larger in diameter than the part C to insure unimpededl rotation. For effecting therequisite connection between the disk A and bobbin B we furnish the former with a split tube D, coincident with the central hole therein and having an internal diameter slightly greater than ythe part C and being of an external size to iit tightly into the usual hole traversing the length of the bobbin. To assist this connection, `we may slit a portion of the tube D to render it resilient, as shown at E E,'Figs.` 2 and 4, or we may provide pins F F on the diskA, as illustrated in Fig. 2, for penetrating the bobbin end. We i'ud the .tube I) to be quite efficient alone, and we prefer to adopt it, though, as will be obvious, we'may use the pins F F as' the only means of fixture. G is a ring or washer, of felt, rubber, or other soft material, intervening and tightly pressed between the bobbin B and'disk A to prevent the thread catching under the bobbin. We recommend its employment; but it is not absolutely'necessary, as the purpose served by it and just e'Xpla'ined will usually be met by pressing the bobbin tightly against the disk. l-I indicates the arm of the machine,between which and the disk A another disk J is interposed. This disk J, as will be clearly seen IOO from Fig. 2, is formed with a recess wherein the diskA is located, so as to be freely revo luble on unwinding the thread from the bobbin B, while the disk J remains stationary upon the holder C and the arm H. To procure this xture of the disk J, it is united to the holder C in much the same fashion as that already described in joining the disk A tothe bobbin B, a split tube K' being provided centrally upon the disk J, wherein, to coincide with the tube, a hole is made through which the holder C passes to be gripped by the upper part ofl the tube K. On the disk J we form or ix a guard or shield L for partiallyinclosiug andextendingabove or toward the top of the bobbin, thereby electually preventing any loosecoils forming at the upper part of said bobbin from falling outside of the disks A and J. Figs. 3 and 4, respectively, show the disks J and A (that are combined in use, as above explained) apart. As will be evident, by this disposition the diameter of the disk A need not exceed and the diameter of the disk J need only slightly exceed that of the bobbin B, so that a ledge M is obtained. Hence compactness and neatness result. Thus it will be seen that the disk A and bobbin B revolve together, and as the thread is unwound any coils becoming slack and falling fall upon the ledge M, whereon they are retained clear of the spindle or holder C, while they are also prevented from getting underneath the bobbin by the washer G. Consequently entanglement and breakage are avoided simply and effectually by a device that may be produced at a small cost and takes up little room in use.
What we claim as our invention, and desire to secure by Letters Patent, is-
In combination with an arm of a sewingmachine and the spindle thereon to receive a bobbin, a recessed disk carried by the arm around said spindle and retained stationary by the engagement of a gripping device carried by it with the spindle, a rotatable disk of slightly larger diameter than the bobbin end and located in the recess in the stationary disk, said rotatable disk being provided with a split tube whereby the bobbin is attached to it, a disk or washer between the bobbin and the rotatable disk and adapted to form a ledge covering the space between the rotatable disk and the fixed disk on which loose coils of thread are received, and a shield or guard carried by the stationary disk and arranged so as to partially surround the rotaa table disk and the bobbin for preventing any loose coils forming at the upper part of the bobbin from falling outside of the disks, substantially as described.
In Witness whereof WeN have hereunto set our hands in the presence of two witnesses.
