Sept. 1, 1953 A. wEsTALL- MOUNTING FOR SPINDLES Filed Jan. 5; 1951 7 wllllll ll ll l iii! Ell Patented Sept. 1, 1953 MOUNTING FOR SPINDIJES Arthur Westall, Accrington, England, assignor to T. .M. M. iResearch) Limited, Rossendale, England Application January 3, 1951, "Serial No. 204,145 In Great Britain June 23, 1950 6 Claims. 1
The invention has reference to the mounting of the spindles in textile spinning and analogous machines. In known terms of such machines it is customary to support the spindles at a point below the "yarn or like package, 'i. e. below the point of application of the load applied to the spindle, and where the load is unbalanced for any reason such an arrangement may be productive of damaging results due to the severe vibration of the spindles when rotating rat or above a critical speed. Such vibration may he unohjec-tionable at speeds below the critical range, but the difficulty arises in connection with existing types of uptwister machines for the reason thatthe critical range occurs at a high value close to that of the desired working speed, so that speeds below the critical range are too low for the desired high rate of production, whilst it has not been found practical to attain a spindle-speed in excess of the common critical figure oi from 7000 to 12000 R. P. M. according to the size of load carried.
The present invention has accordingly for its object to propose an improved form of mounting for spindles by which the above disadvantage is avoided, and in which the critical spindle speed :will be considerably lower than, and preferably not appreciably higher man one-quarter of the desired operating speed, so that the spindles may be operated at speeds substantially exceeding by a safe margin the critical range at which undesirable vibration would occur were they maintained at that speed.
In a spindle mounting according to the invention the bolster comprises a tubular extension including a resilient bushing in which is supported a tube incorporating bearings for a spindle mounted co-axially therein, said bushing being located at a point approximately coincident with that occupied by the dynamic centre of a yarn package wound or carried on the spindle, and the arrangement being such that the spindle and its load are capable of gyrating about the centre of the resilient bushing. The bolster is preferably mounted on its support in such manner as to be capable of yielding resiliently to oscillatory loads due, for example, to an unbalanced load on the spindle.
The spindle bearings in said tube may include a footstep hearing at the base of the latter, en-
closed by an oil-reservoir within the bolster, and
a journal bearing situated near to the aforesaid resilient bushing.
A seating for a yarn package or bobbin is conveniently provided by a sleeve fitting over the -with reference to the accompanying drawings,
which drawings include a longitudinal of a-spin-ning spindle having its mounting constructed in accordance with the invention (Fig. l), a fragmentary detail (Fig. 2) of the mounting shown in Fig. 1 (dream to a larger scalei, and a longitudinal section of an uptwister spindle mounted in accordance with the invention (Fig. "39.
Referring to the drawings it will be seen that the spindle bolster l is made with a circumierential shoulder 2 and a longitudinal shank 3 screw-threaded at its extremity. The shank 3 projects through a hole in the spindle rail or the like 4 so that the shoulder 2 seats upon an upper plane surface thereof, a flexible washer 5 lacing interposed between the adjacent surfaces of shoulder 2 and rail 4. A helical spring 6 is compressed upon the shank 3 by locknuts 1, 8 screwed on its extremity, the spring 6 hearing at its upper end against the undersur-face of the rail 4 through the medium of a second flexible washer 0 (see Fig. 3). Alternatively, a shouldered sleeve 10 may be inserted between the shank 3 and the aperture in the spindle rail, the spring 6 being arranged to bear against the projecting end of the sleeve I0 and an annulus I I fitted over the same, as shown in Fig. 1. These arrangements permit the bolster l to yield laterally in response to an unbalanced oscillatory load on the spindle.
The remainder of the bolster l consists of an upward tubular extension I2 in the top of which is inserted a resilient bushing in the form of a short sleeve I3. This sleeve l3 receives a tubular insert 14 which is housed within the tubular portion l2 of the bolster and extends downwardly inside the latter. At its base said insert I4 is plugged by a footstep bearing I 5 in which the bottom end of the spindle I6 is mounted, a suitable passage I 1 being drilled in the side of the bearing to provide access thereto of lubricating oil contained in the cavity l8 within the bolster, which cavity constitutes a reservoir therefor. At the upper extremity of the tubular insert I4 the spindle I6 is supported by a roller-bearing I9, or other suitable anti-friction journal bearing, this bearing l9 being situated in close proximity 3 to the resilient bushing l3 carrying the tubular insert M.
The cop 20 (Fig. 1) or bobbin 2| (Fig. 3), is carried on the spindle l'6 or I 6' (Fig. 3) by a sleeve 22 or 22' (Fig. 3) of skirt-like form, fitting at the top upon a tapered annular sleeve 23 or 23 (Fig. 3) mounted on the upper end of the spindle, and extending downwardly to enclose the bolster I. At its lower extremity said skirtlike sleeve 22 may provide a mounting for driving wharve 24, as shown in Fig. 1. Alternatively, the lower end of the sleeve 22' may itself constitute part of the spindle wharve, as in Fig. 3, a flange 25 being fitted to the sleeve to provide a support for the base of the bobbin 2!, said flange being provided with pegs ,or lugs 26 which engage sockets 21 in the face of the bobbin base, providing a positive driving connection between the wharve and the bobbin 2|.
The resilient charact r of the bushing I3 carrying the tubular insert l4, being located at or very close to the dynamic centre of the cop or bobbin and the yarn package wound thereon, is effective to absorb spindle and bobbin vibration and to counteract the asymmetrical effect of any unbalanced couples. The flexibility of the bushing l3 permits the insert l4 to oscillate without transmitting undue stresses to the spindle H3 or to the bearing l9, giving smooth operation and considerably higher speeds with a low power consumption.
The constructional arrangement provides an ample lubricant reservoir ensuring adequate bearing lubrication under all operating conditions, and permits the utilization of much smaller parts than have hitherto been used in spinning,
. twisting and doubling spindles.
porated in said tubular insert for supporting a spindle blade coaxially therein, said bushing being located at a point approximately coincident with the center of the full yarn package to be carried on the spindle, so that the spindle and the yarn package are capable of gyrating about the center of the resilient bushing.
2. A spindle mounting as set forth in claim 1, means for resiliently supporting said bolster from said spindle rail so that the same is capable of yielding resiliently to an oscillatory load on the spindle.
3. A spindle mounting as set forth in claim 1, said bearings including a journal bearing mounted near said resilient bushing and a footstep bearing mounted at the lower end of the tubular insert, said tubular extension forming an oil reservoir enclosing the footstep bearing.
4. A spindle mounting as set forth in claim 1, comprising a sleeve fitting over said spindle blade, said sleeve having a skirt extending downwardly over said bolster, and a driving wharve mounted on the lowest extremity of said skirt.
5. A spindle mounting as set forth in claim 1, comprising a sleeve fitting over said spindle blade, said sleeve having a skirt extending downwardly over said bolster, a driving wharve formed by the lowest extremity of said skirt, and a flange surrounding said skirt to provide support for a bobbin.
6. A spindle mounting as set forth in claim 5, comprising upstanding lugs on said flange to provide driving means for said bobbin.
