- This invention relates to the improvement of sound reducing housing means for textile yarn processing machines having spindle assemblies for reducing undesirable sound produced in the yarn processing machine and which are characterized by providing access to the spindle assemblies for servicing while also reducing sound during such servicing.
- the main source of noise in such yarn processing machines are the spindle assemblies and it has heretofore been proposed to provide sound insulating devices on the yarn processing machines themselves and particularly on the spindle assemblies.
- all of these prior proposed sound insulating devices have not been completely satisfactory for eliminating undesirable sound produced in such yarn processing machines and particularly have not been successful in providing sufficient access to the operating parts of such yarn processing machines for servicing while still reducing sound produced by such machines during servicing of individual spindle assemblies.
- the prior proposed devices have included housing means which when opened for providing access to a particular spindle assembly will open access to all spindle assemblies, or, if associated with individual spindle assemblies, when opened do not shield noise from the interior of the machine.
- the above object may be accomplished by providing sound reducing housing means for textile yarn processing machines having a plurality of spindle assemblies arranged in side-by-side relationship in two longitudinal, generally parallel rows along the respective outsides of the yarn processing machine.
- the sound reducing housing means comprises stationary housing elements and movable housing elements mounted on the yarn processing machine for cooperating with each other for at least partially encapsulating the spindle assemblies and for shielding the interior of the yarn, processing machine.
- the movable housing elements are displaceable to positions for allowing access by an operator to certain portions of the spindle assemblies for servicing while the stationary housing elements continue to reduce undesirable sound produced by the yarn processing machine.
- the movable and stationary sound reducing housing elements comprise elements at least par- .2 tially encapsulating each spindle assembly of the yarn processing machine individually or in groups of predetermined numbers and which allow selective access by an operator to certain portions of each individual spindle assembly or group of spindle assemblies for servicing of the selected spindle assembly or group of spindle assemblies.
- the stationary housing elements comprise sound absorbing material and the movable housing elements comprise sound reflecting material so that undesirable sound produced by the yarn processing machine will be reduced by the movable housing elements reflecting the undesirable sound for absorption by the stationary housing elements.
- the stationary housing elements preferably comprise common longitudinally extending walls which may extend vertically, horizontally or at angles to the vertical and horizontal interiorly of the machine and along each of the rows of spindle assemblies for cooperative relationship with the movable housing elements.
- the movable housing elements may be of various constructions, as discussed more specifically below, for at least partially encapsulating each spindle assembly or a group of a predetermined number of spindle assemblies for movement from a first position in which the spindle assemblies or certain portions of the spindle assemblies are substantially closed off from the outside of the machine to positions in which selected portions of the spindle assembly or group of spindle assemblies is opened from the outside for servicing while cooperating with the stationary housing elements for shielding noise from the inside of the machine and the remaining spindle assemblies.
- undesirable dirt, lint, fly, etc. may accumulate within or internally of the yarn processing machine and it may be desirable to include a suction, venting means associated with the housing means for removal of undesirable lint, dirt and other foreign particles contained internally of the yarn processing machine as a result of the housing elements.

SOUND REDUCING IIOUSINGS IN TEXTILE YARN PROCESSING MACHINES This invention relates to the improvement of sound reducing housing means for textile yarn processing machines having spindle assemblies for reducing undesirable sound produced in the yarn processing machine and which are characterized by providing access to the spindle assemblies for servicing while also reducing sound during such servicing.
In textile yarn processing machines, such as twisters, spinning frames or the like, noise is produced during operation of such machines at a relatively high sound level which is very disagreeable for the person or persons operating the machine. Both the machine manufacturers and the textile industry have been working for years on ways of reducing this undesirable sound. This problem has become particularly acute in recent times and environmental qualities of many manufacturing operations, such as textile manufacturingoperations, have become the subject of muchstudy and proposed governmental controls.
The main source of noise in such yarn processing machines are the spindle assemblies and it has heretofore been proposed to provide sound insulating devices on the yarn processing machines themselves and particularly on the spindle assemblies. However, all of these prior proposed sound insulating devices have not been completely satisfactory for eliminating undesirable sound produced in such yarn processing machines and particularly have not been successful in providing sufficient access to the operating parts of such yarn processing machines for servicing while still reducing sound produced by such machines during servicing of individual spindle assemblies. The prior proposed devices have included housing means which when opened for providing access to a particular spindle assembly will open access to all spindle assemblies, or, if associated with individual spindle assemblies, when opened do not shield noise from the interior of the machine.
Accordingly, it is the object of this invention to overcome the above discussed prior disadvantages and others and to provide sound reducing housing means for textile yarn processing machines for reducing undesirable sound produced in such yarn processing machines and which are chracterized by providing access to the spindle assemblies thereof for servicing while also reducing sound during such servicing.
It has been found by this invention that the above object may be accomplished by providing sound reducing housing means for textile yarn processing machines having a plurality of spindle assemblies arranged in side-by-side relationship in two longitudinal, generally parallel rows along the respective outsides of the yarn processing machine. The sound reducing housing means comprises stationary housing elements and movable housing elements mounted on the yarn processing machine for cooperating with each other for at least partially encapsulating the spindle assemblies and for shielding the interior of the yarn, processing machine. The movable housing elements are displaceable to positions for allowing access by an operator to certain portions of the spindle assemblies for servicing while the stationary housing elements continue to reduce undesirable sound produced by the yarn processing machine.
Preferably, the movable and stationary sound reducing housing elements comprise elements at least par- .2 tially encapsulating each spindle assembly of the yarn processing machine individually or in groups of predetermined numbers and which allow selective access by an operator to certain portions of each individual spindle assembly or group of spindle assemblies for servicing of the selected spindle assembly or group of spindle assemblies. It is also preferable that the stationary housing elements comprise sound absorbing material and the movable housing elements comprise sound reflecting material so that undesirable sound produced by the yarn processing machine will be reduced by the movable housing elements reflecting the undesirable sound for absorption by the stationary housing elements. I
The stationary housing elements preferably comprise common longitudinally extending walls which may extend vertically, horizontally or at angles to the vertical and horizontal interiorly of the machine and along each of the rows of spindle assemblies for cooperative relationship with the movable housing elements. The movable housing elements may be of various constructions, as discussed more specifically below, for at least partially encapsulating each spindle assembly or a group of a predetermined number of spindle assemblies for movement from a first position in which the spindle assemblies or certain portions of the spindle assemblies are substantially closed off from the outside of the machine to positions in which selected portions of the spindle assembly or group of spindle assemblies is opened from the outside for servicing while cooperating with the stationary housing elements for shielding noise from the inside of the machine and the remaining spindle assemblies.
Due to the enclosing nature of the housing elements of this invention, undesirable dirt, lint, fly, etc. may accumulate within or internally of the yarn processing machine and it may be desirable to include a suction, venting means associated with the housing means for removal of undesirable lint, dirt and other foreign particles contained internally of the yarn processing machine as a result of the housing elements.
Some of the objects and advantages of this invention having been stated, other objects and advantages will appear from the following more detailed description when taken in conjunction with the accompanying drawings, in which:

and
FIG. 14 is a partial, front, elevational view corresponding to FIG. 13.
Referring now to the drawings, as may be seen from the above figure descriptions, there are eight embodiments of the sound reducing housing means disclosed. These housing means are all illustrated in a 2-for-1 textile yarn twister. It is to be understood that, while eight specific embodiments are illustrated and will be described, the invention is not limited to these specific embodiments and other embodiments utilizing the novel features of these embodiments may be utilized. Also, while the sound reducing housing means of this invention are illustrated and described for use in a 2- for-l textile yarn twister, it is to be understood that these housing means could also be utilized with other textile yarn processing machines.
As well known to those with ordinary skill in the art, textile yarn 2-for-1 twisters utilize a plurality of spindle assemblies, generally indicated at 10, for processing of textile yarn and which are arranged in side-by-side relationship (as shown in FIG. 1) in two longitudinal, generally parallel rows (as shown in FIG. 2) along the respective outsides of the textile yarn twister. Full details of the textile yarn twister have not been illustrated in the drawings inasmuch as these details are well known tothose with ordinary skill in the art and these full details are not necessary for an understanding of the present invention.
Broadly, each of the spindle assemblies 10 carry a package P of yarn Y in which the yarn Y is withdrawn from the package P and processed by twisting in a manner well understood by those with ordinary skill in the art. The spindle assembly 10 includes a driven rotor mechanism, generally indicated at 11, which includes a whorl 12 suitably rotatably mounted on the twister frame 13 and rotated by a continuous belt drive 14 in a well known manner. Spindle assembly 10 further includes a carrier mechanism 16 for carrying the package P of yarn Y and which is rotatably mounted on the rotor mechanism 11 so that the rotor mechanism may rotate relative thereto. The carrier mechanism includes a basket device 18 which surrounds the package P of yarn Y. Complete details of the rotor mechanism 11 and the carrier mechanism 16 are not illustrated in the drawings inasmuch as these complete details are not necessary for an understanding of the present invention.
During yarn processing or twisting, yarn Y is withdrawn from the package P and is threaded through the various mechanisms for twisting or processing of the yarn which results in the formation of a balloon of yarn around the package and around the basket device 18. For restraining the size of this balloon of yarn, a hollow balloon restrainer mechanism 19 is mounted around the above described mechanisms of the spindle assembly 10 and around the rotating balloon of yarn (as shown in FIG. 1). The yarn Y is led from the above described mechanisms through a pigtail guide 24, around a pre-take-up roller 25 and to a traversing device 26 from which it is wound onto a package roll 27 carrying a suitable bobbin or carrier for receiving the traversely wound yarn Y after it has been twisted. The package roll 27 is rotated by a drive roll 28 in a manner well known to those of ordinary skill in the art.
For purposes of reducing undesirable sound during operation of the textile yarn twister, sound reducing housing means are provided. Referring firstly to the first embodiment of sound reducing housing means illustrated in FIGS. l3, stationary housing elements in the form of a generally vertically and longitudinally extending wall 30 of suitable sound absorbing material is mounted in any convenient manner on the textile yarn twister machine internally of the machine and extends between the rows of spindle assemblies 10 along the length of the rows (as shown in FIGS. 1 and 2). The stationary housing elements further include a generally longitudinally extending wall of sound absorbing material 31 connected with the top of the vertically extending wall 30 and extending outwardly therefrom generally along the top portions of the two rows of spindle assemblies 10 along the length thereof (as shown in FIGS. 1 and 2). These top walls 31 of sound absorbing material include downwardly extending flange portions 32 on the outer ends thereof. The stationary housing elements further include generally longitudinally and horizontally extending walls of sound absorbing material 33 suitably mounted on the machine frame and extending along the bottom portions of the rows of spindle assemblies 10 along the length thereof (as shown in FIGS. 1 and 2). Also included are vertically and longitudinally extending walls 34 of sound absorbing material connected with the front edge of the horizontally extending bottom walls 33 and extending along each of the rows of spindle assemblies 10 (as shown in FIGS. 1 and 2).
The movable housing elements of the first embodiment of sound reducing housing means illustrated in FIGS. 1-3 comprise separate, hollow, generally cylindrical housing elements 40 associated with each of the spindle assemblies 10 and mounted for'rotation on stationary ring members 41 carried by the spindle assemblies 10 so that the cylindrical housing elements 40 rotate about the axis of each of the spindle assemblies 10. Each of the hollow, generally cylindrical housing elements 40 are constructed of suitable sound reflecting material and include cut out portions 43 and 44 which define access openings in the cylindrical housing elements 40. These access openings, defined by the cut out portions 43 and 44, are located at generally the top and bottom portions of the spindle assemblies 10 and generally within one-half of the circumference of the cylindrical housing elements 40.
