United States PatentO SPINDLE MOUNTING Ernest D. Meadows, Atlanta, Ga., assignor to Meadows Manufacturing Company, Atlanta, Ga., a corporation of Georgia Application February 23, 1949, Serial No. 77,724

8 Claims. (Cl. 57-130) My invention relates to improved means for mounting rotating bodies, and in particular to a textile-spindle mounting. I

It is an object of the invention to provide an improved device of the character indicated.

It is another object to provide an improved spindle mounting wherein the rotating body may be permitted freely toseek and to maintain its own natural axis of rotation.

It is a further object to provide a unit-handling resilient mounting that may be applied to existing spinning. frames without requiring modification of the frame.

It is still another object to meet the above objects with a device to which spindle means may be removably secured, so that once said device has been properly located on a rail, further spindles may be secured to said device without requiring further alignment to locate the spindle center on the rail.

Other objects and various further features of the invention will be pointed out or will occur to those skilled in the art from a reading of the following specification in conjunction with the accompanying drawings. In said drawings, which show, for illustrative purposes only, a preferred form of the invention:

Fig. 1 is a vertical sectional view of a spindle assembly mounted upon a spinning rail in accordance with the invention;

Fig. 2 is another form of spindle also mounted upon a spinning rail in accordance with the invention;

Fig. 3 is a fragmentary vertical sectional view of a modified spindle-mounting means, shown in application to the mounting of a spindle similar to that of Fig. 1; and

Fig. 4 is another fragmentary vertical sectional view of a further modified spindle-mounting means.

Briefly stated, my invention contemplates an improved mounting for textile spindles and for similar rotating bodies, in which resilient support is provided for the rotating body. The support may be longitudinally relatively firm and yet provide substantially complete freedom (within limits). for the rotating body to seek and to maintain an axis of rotation determined by the loading In the forms to be described, the mounting means which makes possible such resiliency is a separate unit which may be applied to existing splnning frames with little or no modification.

Referring to Fig. 1, my invention is shown in application to the mounting of a spindle 5 upon a spinning frame or rail 6. The spindle 5 may include an upwardly extending blade 7 driven by a whorl 8. The whorl 8 may be revolubly supported by antifriction-bearing means 9 on a relatively fixed and nonrotating stud member 10. The stud 10 may include a generally cylindrical and longitudinally extending base 11 to be secured to the rail 6.

In accordance with the invention, I provide for the relatively longitudinally extensive resilient support of the stud 10 at the mounting base 11 thereof, and such support may utilize a relatively longitudinally extensive layer or sleeve 12 of resilient material. In the form shown, the resilient sleeve 12 engages and spaces two relatively rigid sleeve members. The inner sleeve member 13 may closely fit the cylindrical part or base 11 of the stud 10, and the outer sleeve 14 preferably passes through the mounting opening 15 in the rail 6 with a certain amount of radial clearance in order to permit proper location of the spindle 5 on the rail 6.

The stud member 10 may include securing means for tightly clamping the support portion or base member 11 to the inner sleeve 13. In the form shown, these members are clamped together by fitting a flanged portion 16 of the stud 10 against the upper end of the inner sleeve 13, and a tightening nut 17 threaded to the bottom of the stud 10 may engage the bottom of the sleeve 13. In like manner, the outer sleeve 14 may include an upper flange 18 to engage the upper surface of the rail 6, and a nut 19 may be threaded to the outer surface of the outer sleeve 14 for tightening against the lower side of the rail 6.

In the form shown, the rigid sleeves 13-14 form a single unit with the resilient sleeve 12. The resilient sleeve 12 may be bonded to one or to the other of the rigid sleeves 13-14, and in a preferred form the resilient giaterial is bonded intimately to both rigid sleeve memers.

In order to permit fullest possible freedom for axial cocking of the spindle 5 with respect to the rail 6 (as when the spindle is rotated with an eccentric load), there is preferably an axial clearance between the inner sleeve 13 (or parts carried by the inner sleeve 13) and the outer sleeve 14. To assure that the spindle will never be dropped into contact with the rail, I prefer that the inner sleeve member be provided with an upper guard flange 20 which preferably extends radially outwardly to overstand parts of the outer sleeve 14. The flange 20 may thus be in axial clearing relation with the upper end of the outer sleeve 14.

In Fig. 2, I show an application of my invention to the resilient mounting of a spindle 25, including a blade 26 and a longitudinally extending bolster 27 extending into the well of a base member 28. The spindle 25 may be revolubly supported in the base member 28 by antifriction bearing means 29 and by a lower locating support or bearing 30. As in the case of the first-described arrangement, relatively longitudinally extensive resilient means may be employed in the mounting of the base member 28 and hence of the spindle 25. .Such resilient means may include a sleeve 31 of resilient material bonded to a sleeve member 32 to be secured to a spinning rail 33. Both the resilient sleeve 31 and the mounting member or sleeve 32 may be relatively longitudinally extensive so as to provide similar longitudinally extending resilient support for the base member 28. In the form shown, the resilient mounting is a complete unit comprising a concentric sandwich between the rigid outer sleeve 32 and a rigid inner sleeve 34, the inner sleeve 34 being clamped to the base member 28, as between a fixed abutment 35 and a threaded abutment 36 on the base member 28. The securing means for the outer sleeve 32 may include an upper flange 37 and a nut 38, and, as in the case of the first-described arrangement, I prefer that there shall be axial clearance between radially overstanding parts of the inner and outer sleeves 3234.

In Fig. 3, I show a modified spindle-mounting means suitable for mounting either of the types of spindle disclosed in Figs. 1 and 2, but shown in application to a stud-mounted spindle of the Fig. 1 type. In Fig. 3, I again employ-an adapter assembly which, once located upon the rail 40, need not be disturbed so as to require realignment of the spindle center whenever a spindle may have to be removed and replaced. The mounting means of Fig. 3 may include an outer sleeve member 41 with an integral seating flange 42 peripherally to engage the upper side of the rail 40. The sleeve 41 may be externally threaded to receive a securing nut 43, which, in conjunction with the washer 44, may hold a given adjusted spindle-centering setting of the sleeve 41 with respect to the rail 40.

As in the case of the other described forms, the mounting means may additionally include a sleeve 45 of resilient rubber or rubber-like material which may, if desired, be bonded to the sleeve 41. The sleeve 41 may also include a radially inwardly projecting flange 46 defining an opening 47 having radial clearances with the spindle base 48. A seating flange 49 on the base 48 may rest directly on the resilient sleeve 45, or, as I have shown, the flange 49 may be seated upon the flange 46 of sleeve 41. The assembly may be completed upon the application of a securing nut 50 and washer 51 against a shoulder 52 at the reduced threaded end 53 of the base 48.

I prefer that the inside dimension of the resilient sleeve 45 prior to application of a spindle base shall be such as readily to'receive the spindle base upon insertion'of' the same, and that when so inserted the lower end of the resilient sleeve 45 shall project slightly beyond the abutment or shoulder 52 against which the take-up means 5051 is to be driven: It will b'eunderstood,therefore, that upon such take-up of' the nut'50 the resilient-sleeve will be longitudinally preloaded and, therefore, slightly radially stressed so as to provide sin-adequately tight fit of the'resilient sleeve 45 on the base'48;

InFig. 4, I show a modification of the structure-of Fig. 3 in which a coil spring 55 is employed in place of the resilient sleeve 45ofthe structure of Fig; 3. The same sleevemeans 41 and various securing' and take-up members will be recognized from Fig. 3-, and the spring 55 may be longitudinally compressionally' stressed between the sleeve flange means 46'and the take-up or $6- curing means tl'-51. In order to'allow the spindle to seek and to assume its own axis of rotation, I prefer to allow a radial clearance between thespring 55 and the inner generally cylindrical surface of the sleeve 41. It will-be understood that radial clearance at 47 between the flange 46 and the base 48may'fu'rther promote such freedom of axis displacement,

It will be clear that in all of the forms illustrated I employ an outer sleeve (14, 32, 41) which is designed to pass through an opening in the support (6, 33, 40) and in each form there is a whorl support member (11 or 13, Fig. l; 28 or 34, Fig. 2; 48 Figs 3 arid 4.) The whorl support member passes through the outer sleeve heretofore referred to and the whorl support is;used to support a suitable type of rotatable whorl (5, 25). In each case there is a resilient means (12; 31-, 45, 55) confined between the outer sleeve member and the whorl support member for resiliently supporting said whorl support member. The resilient means in every instance illustrated is somewhatlonger axiallythan the outer sleeve member and I employ flange means (such as20, 16, 35, 46) on one of the members-engaging one end of the resilient means. Furthermore, I employin each species illustrated means-including a nut (1-7, 36', 50) threaded on the whorl support member'and engaging the other end of the resilient means so as to confine th'e latter between the said nut means andsaid means'incl'iiding flangemeans whereby the whorl support-member is resiliently supported for the purposes heretoforeset'forth; I I

It will be seen that I have described relatively simple means for providing'a highly effective resilient mounting for a'plurality of conventional-type spinning spindles.

The parts that must be secured to each other may be tightly secured, and there'need never be any worry'a's't'o whether parts are over or under tight. My resilient mounting may be applied to a spindle assembly 'a't'a point distant from the spinning frame, and the only adjustment necessary to adapt such spindles to the spinning trameis a final tight take-up of the

basen'ut

19 or 38 or 43, as the case may be; alternately, once my resilient mounting assembly has been properly located'on' and secured to the rail, spindles maybe removedjand replaced without disturbing the spinning-axis location determined by my resilient assembly; I
