referring now to the drawings , and more in particular to fig1 a noise reducing washer in accordance with the invention is comprised of a pair of coaxial outer washers 10 and 11 , with an intermediate washer 12 coaxial with and sandwiched between the outer washers 10 and 11 . the central holes 13 of the three washers have substantially equal diameters , the diameter being slightly greater than the diameter of a spindle over which the washers are to be mounted . as more clearly seen in fig5 and 6 , the intermediate washer 12 is provided with a plurality of axially extending holes , i . e ., an even number of holes 14 , equally spaced at a common radius . the washer 12 is preferably of a soft resilient material , such as rubber , neoprene or the like . as more clearly seen in fig2 - 4 , the outer washers , such as the washer 10 , is provided with alternating holes 15 and projections 16 at the same radius and of the same total number as the holes 14 of the intermediate washer 12 . the holes 15 and projections 16 may thereby be aligned with respective holes 14 of the intermediate washer . as illustrated in the drawings , the projections 16 preferably have circular cross sections . referring again to fig1 the noise reduction washer in accordance with the invention is assembled with the projections 16 on each outer washer being aligned with a corresponding hole 14 of the intermediate washer , and a corresponding hole 15 of the other outer washer . the projections 16 have a length to extend substantially through the corresponding holes 14 of the intermediate washer , in the unloaded state of the noise reduction washer , whereby , in the loaded state , the intermediate washer 12 is compressed , so that the projections 16 extend slightly or fully into the holes 15 of the other outer washer aligned therewith . in addition , due to the compression of the noise reduction washer in accordance with the invention , in a loaded condition , the intermediate washer is forced to extend radially inwardly , i . e ., to bulge inwardly , to contact the spindle . this contact aids in the centering of the noise reduction washer on the spindle . the outer washers 10 , 11 are preferably of a &# 34 ; hard &# 34 ; plastic material , such as nylon or the like . thus , in the present specification it will be understood that a &# 34 ; hard &# 34 ; plastic material is a plastic material which is not substantially deformed by the mounting of a noise reduction washer on a spindle , while a &# 34 ; soft &# 34 ; material , as employed for the intermediate washer , is a material which is substantially resiliently deformed by the mounting forces employed to mount the noise reduction washer on a spindle . referring now to fig7 therein is illustrated a spindle 20 mounted on the spindle base rail 21 of a spinning frame , employing the washers of the present invention . the spindle 20 has a threaded base 22 extending through a hole 23 in the rail 21 , and one of the composite noise reduction washers 24 is mounted on one side 25 of the rails 21 surrounding the hole 23 , so that the shoulder 26 of the spindle engages the washer 24 . another noise reduction washer 27 of the type illustrated in fig1 is inserted between the other side 28 of the spinning base rail 21 and the nut 29 on the spindle . the nut 29 is tightened adequately to firmly hold the spindle in position . when the noise reduction washers are thus loaded , it is apparent that the projections of the outer washers therein may extend into the corresponding holes of the other outer washers therein . the noise reduction washers in accordance with the invention require only a simple modification of the existing equipment , since it is merely necessary to remove the nut and spindle from the rail , and assemble a noise reduction washer on each side of the rail prior to reassembly . the noise reduction washers in accordance with the invention may be economically and easily produced . in practice , for example , it has been found that the use of the washers results in an overall reduction of noise level of about 4 db ., considering of course that there was no overriding noise from other portions of the machinery . such a reduction in noise level has been found to be adequate , in some cases , to enable an operator to work full time in a room incorporating the noise reduction washers of the invention on the spindles , whereas , previously , the employe could only be present in the room for a portion of a working day , in accordance with present government regulations . the invention therefore results in more economical manufacture of thread , yarn and other textile products , while improving the working conditions for personnel . while the invention has been disclosed and described with reference to a single embodiment thereof , it will be apparent that various modifications may be made therein , and it is therefore intended in the following claims to cover each such variation and modification as falls within the true spirit and scope of the invention .
