UNITED STATES PATENT OFFICE.
JAMES C. FOTTEB, OF PAW'IUCKET, RHODE ISLAND.
SPINNING-MACHINE ROLLER.
Application filed January 8, 1922. Serial No. 528,687.
o the United States, have invented certain new and useful Improvements in Spinmng-Machine Rollers, of which the following is a specification.
In the customary practice, the draw or yarn feedin rollers of spinning machines are made 0 numerous sections which are joined end to end, one roller having on one end a square shank that enters a square socket in the adjoining end of the other section. These square shanks and sockets must be most accurately fittedto avoid any excentricity which would result in wobbling or excentric motion of the rollers with consequent bad efi'ect upon the yarn fed thereby to the spindles. To secure this condltion, the matching ends of the adjacent rollers comprising the square shank on one and the socket in the other must be individually fitted to one another and so, important is 1t that the. square shank of one should be placed in the socket of another to which it has been conformed that they are marked 1 by numbers to assure correct assemblage.
Obviously this accurate fitting of one section to another makes their construction costly and should it be necessary to replace a section after it had been in use, the new section, to the ones in the machine with which it is to be used, must be carefully and accurately made, which, of course, is an expensive operation. The object of my invention is to provide means for connecting the sections of these rollers which will assure accurate or true alinement of the sections forming a complete roller, which will be much less costly, will make unnecessary the individual fitting or adaptation of the cooperating junction parts of roller sections and so that there may be interchangeability, that is to say, so that it be a matter of indifference in assemblage of the sections to form a roller what particular sections are placed adjacent to one another, and which since it must be accurately fitted' will result in other advantages. For the attainment of this object, my invention con slsts in what is defined by or included within the terms or scope of the appended claims.
In the accompanying drawings which illustrates an embodiment of my invention in a most advantageous form,--
Fig. 1 is a view partly in side elevation and partly in longitudinal section of several united sections 0 a draw or feed roller of a spinning machine; I
Fig. 2 1s a section on the line 2-2 of Fig. 1; ig. 3 is a section on the line 3-3 of Fig. 1;
Fig. 4 is a detail view in perspective of an end portion of one of the roller sections.
The sections forming a roller have lengths corresponding to the spacing of the roller stands, these stands, for instance, being spaced about eighteen inches, center to center, the distance depending upon thelength of the box of spindles. The peripheries of the rollers are fluted, the fluted portions not being continuous from end to end of the roller but being of equal length and separated by annular spaces. In accordance with my invention, I form on the end of one roller section, 10, and preferably upon both ends thereof a cylindrical journal-forming portion, 11. which is placed in the customary half round depression in the roller stand. Beyond the journal, 11, I form a cylindrical portion, 12, of less diameter which is truly concentric with the roller and the journal and from such portion, 12, extends a tang, 13, which in cross section is polygonal and preferably is square. The adjacent roller section, 14, has in each end an axially extending cavity which includes a cylindrical portion, 15, of a diameter to receive the cylindrical part, 12, of the roller, 10, with a close fit, the fit being a press fit, to assure the tight connection of the adjacent sections suflicient to or complementary parts roller, 14, the recess has a socket, 16, whose form in cross section matches that of the tang, 13, so that the latter may be received therein and thereby the two roller sections be rotatably connected together. The cylindrical portion, 12, of the recess is made truly concentric with the roller, 14, for it together with the fitting cylindrical portion, 12, of the section, 10, besides serving as means toconnect the sections against accidental separation constitutes the means for that accurate centering of the sections which is indispensable. Since the function of the tang, 13, and its socket, 16, is simply to rotatably connect adjacent sections, no close fitting of tang to socket is necessary and in practice they have a loose fit. When the tang and socket are square in cross section, the socket may be formed by a drill that will bore a square hole and the tang may be formed by milling to produce its flat sides. It will thus be seen that my section-connecting device comprises first the accurate centering means conslsting of the cylindrical portion, 12, on one section and the cylindrical recess or chamber, 15, in the other section, and means for connectin the two sections so that they rotate together which desirably, because of ease of manufacture and assemblage, but not necessarily, as far as the broad scope of'my invention is concerned, consists of the uare tang on one section and the corresponding socket therefor in the other section.
It will be evident, that since the matching which form the connectlng means between adjacent sections can made uniformly alike in the sections going to make up a roller by operations which assure duplicate formations and do not call for individual fitting of complementary parts, that cost of manufacture is reduced and in the original assemblage as well as in substitution for repairs or replacement it is a matter of indifference what particular sections are put together, and as I prefer, since each section has a symmetrical formation at each end, one section member and the other member being a true female member, a section may be reversed end for end and thus should the flute edges, as a result of long use be impaired on one side, the other side of such edges by reversal of the section may be put into use and thus the useful life of the section prolonged.
It will be seen that the operations required for producing the journals, 11, on the male members and the matching cylindrical portions of the centering means are merely turning operations followed by grinding which can be readily pe formed under conditions that give true concentricity and in the case of the tang, 13, and its socket, 16, the latter, as I have already explained, is formed by a drill capation and being thus a true male aeoaaaa ble of boring a square hole while the tang is formed first by turning it into a cylindrical shape and then its sides milled to make them fiat.
What I claim is:
' 1. A roller of the kind described composed of sections placed in alinement, adjacent sections having centering means consisting of a round portion on one section and a corresponding recess in the other section, said round portion and said recess being concentric with their respective sections,
and means that connect the. sections that g socket in the other section that is a continuation of said recess.
3. A roller of the kind described composed of sections placed in alinement, adj acent sections having centering means consisting of a cylindrical portion on one seea corre onding recess in the other section, said cylindrical portion and said recess being concentric with their respective sections, and means that connect the sections that comprises coacting parts within an inward extension of said recess.
4. A roller of the kind described comprising sections placed in alinement, one of a pair of adjacent sections having a cylindrical journal-forming portion and a round portion extended from such journal-form-- 1ng portion, the other of said pair of sections having a round recess in which said round portion fits, said recess and said round portion being concentric with the journal-forming portion, and means connecting such sections together that comprises coacting parts within an inward extenslon of said recess.
5. A roller of the kind described comprising sections placed in alinement, one of a pair of adjacent sections having a cylindrical journal-forming portion and a round portion extended from such journal forming portion, the other of said pair of sections having a round recess in which said round portion fits, said recess and said round portion being concentric with the journal forming portion, and means connect? ing such sections together, comprising complementary formations on the two sections that include an angular surface on an inward extension of the recess.
5 means, and the other section of such a pair 6. A roller of the kind described composed of sections placed in alinement, one of a pair of adjacent sections having at both ends similar members to form connecting metrical projections concentric with t e section and the similar formations on the other 10 section being symmet-ncal concentric sockets.
