PATENT OFF ALBERTM..GU'ILLET, OF CHARLOTTE, NORTH CAROIiINA INTERCHANGEABLE JOURNAL BEARING Application filedTannery 10, 1930, Serial No. 419,891. Renewed November 1-1, 1931.

This invention, relates to spinning machinery and more particularly to a method of joining adjacent flutedrolls together so as to cause the rolls to function better. than 5 rolls-equipped with} square necks, and my invention is adapted; to housed, in the manufacture ofnewrollsas well as in the repair of oldrolls.

All of the rolls of spinning machines which carry fluted bosses are usually made in sections, each section carrying upon it a plurality of fluted'bosses and the sections being joined by a neck which forms a journal bearing for the series of rolls and which is formedbeyond the journal bearing with a male square end adapted. to fit within a female, square-or, many-sided socket formed 1n the adjacent end of the next adjacent roll section. Each ofthese necks, as before re- 29 marked, ispnovided with a journal, bearing rotating within a roll stand,ian.d when the journal bearing of. a section becomes worn itis-necessary that itzshallbe reneckechwhich means that the sectionmust be removed from the roll stand, sent to a machine shop, the

neck must be sawed orcut. off adjacent, the junction of the journal portion with the body of, the section, thenthe end of the body section must be bored out, and anew neck hav- 0 ing a journal portion thereon and asquared portion must be driven into thisbore until a driving fit is secured. Also, it might be remarked that due to the vibration between the sections of rolls the squared'lportion becomes a 85 worn and allows playbetween the sections of rolls and this causes the, rollers to be renecked as well as the wearing out of the journal portion. Both of the above causes contribute to the rapid. deterioration of rolls 4 inspinning frames and the like, and calls for an overhauling of the same. "This is a more or less expensive operation and it is not very satisfactory for the reason that it is difficult to get a perfect drive fit between V the newlneck and the body of the section and one that will not permit the neck. to. become loose. i Also by driving the new neck into the end of the old, roll, if a driving fit is secured there is a tendency to swell the ends of the roll and therefore cause the end bosses thereof to become larger than the other bosses, thereby causing thin, uneven yarn.

The general object of my invention is to provide an interchangeable journal with, a combination of a screw and a taper fit for fluted textile rolls and other shafts which may be desired to be secured to each other, which journal may be readil inserted into the extremity of the roll section or removed if necessary, it being an object of my inven- 69 tion to provide a very strong replacement part for oining the section of rolls and one that willnot become broken, and also which will not interfere with the size of the rolls as there is no driving and swelling of the end bosses of the rolls.

Another object of my invention is to pro,- vide an, interchangeable journal for textile rolls and the like which comprises a, journal portion, with an elongated portionextend- 70 ing from the journal portion with a very slight taper thereto, which tapered portion of the section on which the j ournal' portion appears being adapted to fit into the elongated tapered bores corresponding to the taper on. the journal section, said bores being in the ends of the rolls, andproviding, a shoulder portion at the bottom of the tapered portion, and then providing a smaller bore and threadingthe smaller bore and providing a threaded smaller portion on the end of the j ournal portion to fit into thisthreaded bore in the roll. I obtain. ascrew thread'ed fit between the sections otrollsand the j ournal portion, and also obtain a tapered fit which will not allowside play between the roll sections and the journal sections.

In my Patent Number 1,659,261 of February 14, 1928, I show a very steep tapered portion, but this invention is an improven'ient over the structure set forth in said patent, in that I provide a tapered portion in addition to the thread which is a very much elongatedtaper, and prevents any play between the roll sections and the journalportion, and also provides a reinforcing portion of the roll section and the journal section over-lapping to strengthen the screw threaded fit.

Also in, my patent applicationiserial Num- .1

all the way to the point 17 where it has a ber 377,398 which was filed on July 11, 1929 I show an elongated journal portion extending into bores in the rolls with a steep taper thereon, and this invention is an improvement over that structure, in that in the structure set forth in said patent application I provide an extended bore which does not taper, and this untapered bore allows a certain amount of side play between these rolls and the journal section,,and it is an object of this invention to eliminate this side play by having an elongated tapered portion of the journal section fitting into a corresponding tapered portion in the roll section.

Another object of my invention is to provide an interchangeable journal for joining rolls together with both ends of the journal alike,'and thus causing it to be interchangeable under all conditions. 7 I Some of'the objects of my invention having been'stated other objects will appear as the description proceeds, when takenin connection with the accompanying drawing, in which- Figure 1 is aside elevation partially in cross-section showing my invention Figure 2 isa view showing one end of a roll mostly'in cross-section after being bored out and threaded to fit my interchangeable journal; g Figure 3 is a cross-sectional View taken along the. line 33 in Figure 2. In rolls which are manufactured and placed on spinning machinerythe structure which islthe predominating and conventional structure, inwhich a section has a journal portion made integraltherewith, which journal portion is squared and, this squared portionis adapted'to be fitted into a square hole i i-the end of another section, andas pointed out in my objects of invention it has heretofore been necessary in replacing a worn out portionto saw ofif the neck and drill outand inserta' new journal, My i l ofi'" can be appliedeto' old rolls of'thislcharacter 'orfto new rolls, and in ther "case my invention is described best by statingthat the rolls 10 and 11 are first bored 'outin'the endportions thereof by the tar'iered cavity 12, which extends inwardly: to the squared shoulder portion 13 and has the smaller bore 14 which is threaded and I then provide the j ournal member 15 which begins sloplng at the point 16 and slopes gradually shoulder 'atthe point 17 and the smaller portion 18' which is threaded to fit into bore 1 1- m the sections 10 or llas the case may be. Each end of the member 15' has a key hole 19 into which a key can be inserted for removing the journal member11'5 from the sections 10 orll as the case may be, it being evident that a suitable wrench may be used for removing one of the sections 1001' 11 but when one of'the sections is taken off and the journal 15 does not readily come out of the other section, it is impractical to use a wrench unless it should be a friction wrench on the member 15 to cause the threads to disengage themselves from the sections 10 or 11 as the case may be, and in such case a suitable key can be inserted into the hole 19 to unscrew the section 15 from the other roll member 10 or 11 as the case may be.

It is seen that by providing the gradual tapered cavity 12 and providing the tapered portion 21 on each-end of the journal portion 15 to conform to the bore 12, that when the threaded portion 18 is driven home in the threads 14 that a perfectly tight fit will be obtained which will prevent any side play whatever, andwill insure that the rolls will be in perfect alinement when joined together by my new journal member 1:), This arrangement secures-a tight fit between the roll section and the interchangeable journal member which to all intents and pur= poses is as tight as a drive fit, but theshoulder 17 prevents the swelling of the roll due to the fact that this shoulder limits the inward movement of the tapered portion 21 into the bore 12, and at the same time provides avery tight fit which insures that the entire length of rolls which in many cases are as long as forty'feet will be in perfect alinement which would be impossible without this tapered fit extending in the elongated cavity from the edge of the bearing portion of the member 15 back into the roll for an ap reciable distance. In the'drawing and specification'I have set forth a preferred embodiment of my invention, and although specific terms are employed, they are used in a generic and dcscriptive sense only, and not for purposes of limitation, the scope of the invention being set forth in the appended claims;
