OILING DEVICE FOR FIBER SILK AND THE LIKE.

Specification of Letters Patent.

Patented Nov. 8, 1921.

Application filed October 23, 1919. Serial No. 332,693.

To all/whom t may concern:

Be it known that I, JOSEPH JACOBS, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Oilin Devices for Fiber Silk and the like, of w ich the following is a specification.

his invention relates to improvements in oiling devices for fiber silk and the lke.

The object of this invention is to provide any oiling device for fiber silk which may be used in combination with the guiding parts of a knitting machine, and when so einployed, will effectively oil .such silk in its passage from the bobbin to the needles.

Another object of my invention 1s to produce an oiling pot which may be mounted or seated concentrically of the hub of the bobbin rack of the machine'upon the sup porting rod for the concentric guides.

Another object of my inventionis to provide an oiling pad which may be concentrically-arranged about the hub of aA bobbin rack and with the conventional guide pins above such rack and may be suitably fed with oil.

Another object is to provide such a concentric pad with an oil feed pot having a cylindrical seat arranged concentrically with the pad and adapted to fit over the supporting rod for the guiding pins and to abut against the hub of the bobbin rack so as to enable the positioning of the pot and pad intermediate the conventional or standard guide disk and the bobbin rack to the end that the silk or like yarn may be oiled before it reaches the needles.

With these and other objects in view, the invention comprises the combination' of members and arrangement of parts so combined as to co-act and coperate with each other in the performance of the functions and the accomplishment of the results herein contemplated, and comprises in one of its adaptations the species or preferred form illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of the upperportion of a knitting machine embodying my invention;

F ig. 2 is a sectional' view of the oil-pot illustrated in Fig. 1; and

Fig. 3 is a plan view of said oil-pot with the oiling-wick and porcelain wick-bed broken away. A

n Referring now to these drawings, which illustrate a preferred embodiment of my invention, 1 1@l indicates supporting legs which extend from a suitable b ed plate and base members to a cam-ring 2, with which is associated the other conventional parts, if necessary, and in which the needle-cylinder and needles 2a operate and to which the yarn or thread is fed in the conventional manner. 3 3a indicate suitable supporting studs for the conventional bobbin rack 4 and dial arch 5.. The bobbin ra'ck 4 is, as illustrated, provided with a hub 5a and a guide-pin supporting-rod 6 having guide-pins 7 arranged concentrically of the hub and supporting rod 6. The rod 6 also has suitably connected thereto and suitably disposed with relation to the hub and guide pins, the conventional or standardguide-disk 8 having a series of concentric guide-apertures v9. Bobbins l1, provided with raw or unoiled fiber silk, are

mounted concentrically of the hub 5 and rod 6 on spindles 10 and the threads of liber silk 11a are guided from the bobbin up over the guide-pins 7, thence downwardly through apertures 9 in the guide-disks 8 and thence downwardly to suitable thread or yarn guides or carriers associated with the camring 2 and thence in any conventional way to the needles 2a.

The foregoing is a description of the conventional knitting machine and in itself forms no art of my invention.

Mounted concentrically of the bobbins and guiding means for the fiber silk threads and intermediate the bobbin and the needles in the path of movement of the threads 11, I provide an oiling pad 12 which is circulail in conformation and is arranged concentrically of the guide pins 7 and of the apertures 9 in the guide-disks 8. As shown, said pad forms part of a cylindrical wick 12a and the wick and oiling pad are, as illustrated, supported on the rim 15 of an oil pot 13 provided with an axial bore 14 cylindrical in conformation and extending from the bottom to the top of the saine. This bore is preferably formed to conform in shape with the rod 6 so as to enable the pot to be fitted over the same and to enable the seating of the pot concentrically of the bobbins and yarn guides. The pad-supporting rim 15 of the pot 13 preferably extends outwardly and downwardly in a curved supporting flange for the oil-pad 12. Preferably seated cn the flange 15 to form a I smooth hard bed for the Wick 12a is a porce- 'of fiber silk or yarn are lain-rin 16 Which preferably conforms in shape with the iiange and is seated thereon so that the pad 12 Will overlie the same. Obviously when the pot 13 is iilled with oil 17 or similar liquid, the wick 12a will by capillary attraction feed or supply the circular pad 12 with oil and will keep the same properly moistened, so that when the threads guided into contact therewith by the standard guide pins 7 and guide disks 8 of the conventional knitting machine, the said silk will, in its passage from the bobbin to the needles, be properly oiled; and it is also obvious that When the circular pad portion of the Wick 12a is Worn out the cylindrical Wick 12a may be moved up and spread over the porcelain bed 16 so as to renew the pad, and furthermore that the hard porcelain bed will prevent Wear on thel Hange'l of the pot 13.

Having described my invention, l claim 1. An oiling device for knitting machines comprising a cylindrical pot having a vertically-disposed axial bore comprising a cylindrical tube adapted to form a seat for the pot, a circular outwardly-extending marginal flange at the rim thereof as and for the purpose specified, and means for feeding liquid to said flange.

2. An oiling device for knitting machines comprising a cylindrical pot having a vertically-disposed axial bore comprising a cylin drical tube to form a seat 'for the pot, a circular outwardlyextending marginal iiange at the rim thereof and an oiling pad mounted on said rim.

3. An oiling vdevice for knitting machines comprising a. cylindrical pot having a vertically-disposed axial bore comprising a cylindrical tube to form a seat for the pot, a circular outwardly-extending marginal ange at the rim thereof and a bed of suitable Wear-resisting material seated on said ange as and for the purV ose specified.

4.-. An oiling device for knitting machines comprising a cylindrical pot having an axial bore comprising a cylindrical tube to form a seat for the"` pot, a circular outwardly-extending marginal iange at the rim thereof, and a ring of porcelain seated on said flange as and for the purpose specified,

5. In a knitting machine, the combination `With a bobbin-rack having a hub, a guidepin supportingrod connected with said hub; guide pins supported on said bariabove and concentrically of said hub; bobbins supported on said rack having threads supported by said pins, needles'below said rack, anda concentrically arranged oil pad khaving` suitable feeding means and supported in the path of said threads between the bobbins and the needles.

6. In a knitting machine, the combination with a bobbin-rack having a hub, a guidepin supporting-rod connected with said hub; gui-de pins supported on said bar above and concentrically of said hub; a guide disk having apertures on said supporting rod; bobbins supported on said rack having threads supported by said pins and guided by said disk apertures; needles below said rack; and a concentrically-arranged oil pad having .suitable feeding means and supported in the path of the said threads betiveenthe guide disks and needles.

7. ln a knitting machine, the combination withv a bobbin-rack having a hub, a guidepin supporting-rod connected with said hub; guide pins supported on said bar above and concentrically of said hub; bobbins supported on said rack having threads supported by said pins, needles below said rack, l

and an oiling device comprising a cylindrical pot having a bore extending vertically therethrough to form a seating channel for the pot mounted on said rod between the bobbins and needles.

ln witness whereof, l have signed my name to t-he foregoing specification in the presence of tivo subscribing witnesses.

JOSEPH JACOBS. i
