J. J. KEYSER TEXTILE MACHINE WITH CLOSED HOUSING 2 Sheets-Sheet l INVENTOP Sept. 1, 1964 J. J. KEYSER TEXTILE MACHINE WITH CLOSED HOUSING 2 Sheets-Sheet 2 Filed March 30, 1961 United States Patent 3,146,572 TEXTILE MACHENE WETH CLOfiED HOUSING Johann .lacoh Keyser, Grahenallee 16, Aarau, Switzerland Filed Mar. 3! i961, Ser. No. 99,430 4- Claims. (ill. 57-4) The present invention relates to a textile machine, especially a spinning machine with at least one closed housing for protectively mounting drive transmission elements therein.

Each spinning machine comprises a frame or housing having mounted therein all parts required for the textile technological process to be carried out and in which are also mounted the drive transmission elements necessary therefor. The said transmission elements are, as a rule, mounted in closed housings in order to protect the same against undue manipulation. To this end, many spinning machines have at one end thereof a larger housing for the main drive transmission elements and at the opposite end have a smaller housing for receiving further drive transmission elements. Between these foremost drive transmission stations, there are, in conformity with the specific type of machine involved, provided further housings or covers for purposes of protecting for instance sensitive transmission elements against soil or undue manipulation. However, the machine parts which serve the processing proper of the textile material involved are exposed in order to assure a good observation and easy handling at the respective working stations. Occasionally, individual portions of the machine are provided with screens or the like in order to protect such portions for instance against unfavorable air currents as they may be produced by the movement of fast running driving elements. A protection of the entire technological processing range of a machine has, however, heretofore been unknown with spinning machines. Merely in connection with machines which are out of operation for a longer period of time, it is known to cover the machine elements employed for the textile technological process with paper or cloth in order to protect the same against soiling and other harmful influences as they may be caused for instance by the humidity content of the air customary in spinning mills. The same applies also to the transport of such machines if their size will permit transporting the machine in already mounted position.

The requirements put forward by the spinning industry with regard to the increase in the production and improvement of the quality, can with heretofore known devices be met only to a limited extent. This is due to the fact that the climatizing of the machine shop in which the respective machine is mounted can be adjusted only to a general medium value which will meet the processing conditions of the fiber material to a certain degree and will produce air conditions tolerable for the operators of such machines. The air currents caused by rotating machine elements were likewise held within permissible limits. However, a further increase in the production and improvement of the quality of the processed material is not possible without material change in the processing conditions. In other words, it would be necessary to assure that the processing of the fiber material will be effected under the most favorable climatic conditions which are dependent on the maintainance of certain temperatures and of a certain humidity content of the air while harmful air currents must be eliminated as far as possible.

It is, therefore, an object of the present invention so to design a spinning machine that the entire textile technological processing operation of the machine will be carried out while being protected against unfavorable outer influences and that the room in which the machine 3,14%,572 Patented Sept. 1, 1964 is located will be protected against unfavorable influences caused by the machine.

It is a further object of this invention to provide a spinning machine as set forth in the preceding paragraph, in which all sensitive machine parts are covered up toward the outside as far as possible.

These and other objects and advantages of the invention will appear more clearly from the following specification in connection with the accompanying drawings, in which:

FIG. 1 illustrates a diagrammatic cross section through a spinning machine with a protective cover according to the present invention.

FIG. 2 is a view of a portion of a ring spinning machine similar to that of FIG. 1 as seen from the servicing aisle.

FIG. 3 is a perspective view of a pre-spinning machine with a protective cover according to the present invention.

FIG. 4- is a perspective View of a drawing frame with a protective cover according to the present invention.

The objects of the present invention as outlined above have been realized by movably mounting at least one cover extending transverse to the working direction of the machine in such a way that in the outer contour of the total cross section of the machine there is formed a closed housing which is adapted completely to cover or encase the entire technological working field of the machine while said cover is adapted at least sectionally to .be opened.

One of the simplest embodiments of the present invention consists in that at least one cover is located near the zenith point of the total cross section and is movable from this point. Furthermore, there exists the possibility of mounting at least one cover near one outer end of the base of the total cross section of the machine and to make said cover movable from this point.

According to a preferred embodiment of the invention, at least two covers are mounted respectively near the zenith point and near one outer end of the base of the total cross section of the machine and are movable from said two points in such a way that they abut with their ends at a predetermined point along the outer contour of the total cross section. The cover itself may be designed in various manners. Thus, the cover may be so designed that it can selectively be rolled up, but if desired the cover may also be displaceable in form of a plate or may be tiltable in form of a plate. Furthermore, there exists the possibility to arrange two covers in series in such a way that the outer cover is shock-resistant and non-transparent while the inner one is transparent.

Advantageously, the arrangement is so selected that guiding means for the lateral outer edges of the cover are provided in the outer circumference of the total cross section of the machine. When long machines are involved, a cover extending over the total length of the machine is not practical for reasons of operation. In such instances, the arrangement may be such that the cover is subdivided along the length of the machine and that at each partition guiding means for the lateral outer edges of each cover are provided in the outer circumference of the total cross section of the machine.

A cover as set forth above in able fully to meet the requirements outlined above inasmuch as it will in each instance assure a protection of the textile technological working range of the machine to the desired extent. The textile technological working range comprises the fiber feed, the elements for the processing proper of the fiber material, and the depositing of the processed fiber material on the machine. Depending on the type of the machine and the processing operation, the space for the textile technological working range will vary. Within said space, it is possible by means of the cover according to the invention to create the most favorable climatic conditions for the fiber material with regard to temperature and humidity contents without affecting the free space surrounding the machine and the operators in said free space. Also the air currents which might be produced by an increase in the speed of the machine will have no iriluence on the surrounding free space. The same applies to the air currents in the machine shop as they may be produced for instance by opening and closing of doors.

While with heretofore known machines it was possible to adjust the climatizing of the machine shop merely to a medium value for all machines, the present invention will make it possible to adjust optimum climatic conditions individually for each machine and for the specific fiber material being processed. The climatization of the machine shop may then be limited to the ordinary renewal of air. Also the influence of air currents produced by the machines, which air currents cause the movement of lint and dust, will be obviated by the present invention so that the produced product will be improved and the operator will have better working conditions.

Referring now to the drawings in detail, the ring spinning machine shown in FIG. 1 comprises a frame known per se which includes vertical columns 1, transverse struts 2 mounted near the bottom end of said columns 1, and transverse struts 3 at the upper end of said columns 1. In addition thereto, the frame of the machine comprises cylinder rails 4 extending in longitudinal direction of the machine. Guided on columns 1 are spindle rails 5 and ring rails 6, whereas stands 7 of the creel are mounted on the transverse struts 3, and drafting frames 8 are mounted on the cylinder rails 4.

According to the present invention, covers extending transverse to the working direction of the machine are movably mounted on said machine. These covers follow a line corresponding to the outer contour of the total cross section of the machine. These covers form along said outer contour a closed housing by means of which the total textile technological working range of the machine is adapted to be completely covered. This cover is adapted to be opened at least by sections. According to FIG. 1, the left-hand machine side is provided with a cover 9 for covering the upper portions of the machine, whereas for purposes of forming a housing, a cover 10 is provided at the lower part of the machine. The cover 9 extends approximately from the zenith point of the total cross section of the machine to approximately the height of the transverse struts 3, whereas the cover 10 is journalled near one outer end of the base of the total cross section of the machine and is movable upwardly up to the transverse strut 3. The embodiment of FIG. 1 illustrates the cover 9 as a roll cover the slats of which are joined together by hinges, so that it is possible to fold the slats together in a zigzag manner and to house the same above the creel in a position folded together. On the other hand the cover It) is illustrated as a cover adapted to be rolled up leaving its winding roller 11 journalled on the trans verse strut 2. By pulling the cover 9 downwardly and pulling the cover 10 upwardlly, a housing will be formed which is completely closed along the contour of the total cross section of the machine. The said housing forms a complete cover for the textile technological Working range.

Preferably, the covers are transparent so that from the outside it can be seen if a disturbance should develop at any point of the machine and would have to be remedied. The covers may, however, also be made transparent at those portions only where observations have to be made. For purposes of remedying a disturbance, only that portion is uncovered by moving the cover away where the said disturbance has occurred. For instance for purposes of exchanging an empty pre-yarn bobbin and replacing the same by a new bobbin, it will sufiice to raise the cover 9 so that the creel will be accessible to the operator. If, for instance, a thread break has to be remedied, it is necessary at the respective spinning station to move cover 9 upwardly and cover 10 downwardly so that the fiber strand coming from the drafting frame 8 may be connected to the thread end on the yarn body. After the respective disturbance has been eliminated, the covers are again moved into their closed positions so that unfavorable influences from the outside of the machine will not be able to affect the technological processing operation.

On the right-hand side of the machine of FIG. 1, there are likewise provided two covers 12 and 13 both of which are adapted to be rolled up. The cover 12 winds itself upon a double winding roller 14 near the zenith point of the total cross section of the machine, whereas the cover 13 is adapted to be rolled off from a roller 15 which is journalled at the outer ends of two successive transverse struts 2. At the base of the machine a stationary covering 11' or 15 respectively is provided in longitudinal direction at least at the front side of the cover 19 or 13 respectively. The covering 11' rests with its lower edge upon the floor and extends with its upper edge close to the cover, so that the closed housing extends down to the fioor. The above also applies with regard to the housing formations and the temporary uncovering of the spinning stations for eliminating disturbances.

Instead of two covers 12 and 13, it is also possible to provide one cover only for the entire working range of a machine side so that for instance the cover 13 would extend from the bottom of the machine to the zenith point of the total cross section of the machine.

FIG. 2 also shows the covers 9 and 10 which are arranged on the left-hand side of the machine of FIG. 1. The illustration clearly shows that these covers are closed in the left-hand portion of the drawing, whereas in the right-hand portion thereof the covers 9 and 10 occupy an open position. FIG. 2 also illustrates a closed main drive frame 16 mounted at one machine end for protectively mounting the drive transmission elements which are driven by the electric motor 17 mounted on housing 16. From the main drive frame 16 there will extend the various smaller covered driving housings of which housing 18 covers the drive for the drafting frame 8 whereas housing 19 covers the drive for the spindle in the spindle bank 5. These housings 18 and 19 as well as the parts therebetween are covered from the outside by a hinged protective door 20. A further protective door 21 is likewise hingedly arranged approximately at the level of the electric motor 17. These two doors serve exclusively for protecting the operator against accidents and do not form a part of the invention.

The textile technological working range starts merely adjacent the doors 2t) and 21 and is adapted to be covered according to the present invention. FIG. 2 illustrates that the covers 9 and 10 do not extend over the entire length of the machine but are subdivided so as to form sections corresponding to the distance between two successive transverse struts 3. The outer ends of the extensions 22 connected to the transverse struts 3 form a connecting point for guiding bars 23 which extend along the outer contour of the total cross section of the machine from the bottom portion thereof to a level above the creel and form guiding means for the lateral outer edges of the covers 9 and 10. The guiding bars 23 may in a suitable manner be connected to the lower transverse struts 2 and to the stands 7 of the creel in order to assure a stable guiding for the covers. Above the creel of the machine there may be arranged a stationary plate-like cover 24 which serves as table for the supply bobbins. To both sides of said plate-like cover 24 there may be linked covers 25 adapted to be tilted upwardly so as to furnish a further possiblity also from the top to reach the creel or the ends of the covers with their recesses.

FIG. 3 illustrates a pre-spinning machine which is likewise provided with a cover according to the invention. As will be seen from FIG. 3, due to the shorter overall length of the machine, between the main drive frame 31 and the end drive frame 32 there is provided a one piece cover 33 which extends in longitudinal direction of the machine and is located above the upper portion of the machine. A similar cover 34 is adapted to cover the lower portion of the textile technological working range. Both covers 33 and 34 are adapted to abut along a predetermined circumferential line of the total cross section of the machine. The said line is so selected that by opening one cover, a certain portion of the textile technological working range of the machine is exposed, whereas for instance the lower cover 34 has to be opened merely for exchanging the full bobbins. The covers 33 and 34 have also in this instance their side edges guided in guiding means which are mounted on the inner sides of the main drive frame 31 or end drive frame 32. Depending on the available space, the covers 33 and 34 may have to be displaced merely or can be rolled up. For instance a cover 34 adapted to be displaced is illustrated in FIG. 3, the side edges of which are formed Z-shaped in a manner that the extreme shank engages the guiding means which are mounted on the inner sides of the main drive frame 31 or the end drive frame 32 respectively. The guiding means may be formed as a groove. The cover 34 enters a trough 34' which forms the bottom closing of the machine. The trough 34' extends either to the back of the machine or closes towards to the floor. Similar to the covers 33 and 34 arranged on the front side of the machine, further covers may be provided at the back side of the machine (not shown in the drawing) in order to form a complete closure or housing for totally enclosing the textile technological working range, the said last mentioned housing may be sectionally opened up in conformity with the requirements, for instance for remedying a break in the thread.

FIG. 4 illustrates by way of example a so-called can drawing frame which is likewise equipped with a cover according to the invention. In this instance, the sectional subdivision is eflfected according to the ranges: fiber feed, processing portion proper, and depositing of the processed fiber material. When looking in working direction, a stationary closure wall 35 is provided behind the can feed which wall corresponds to the outer circumference of the total cross section of the machine as it is formed by the two lateral driving frames 36 and 37 of the machine. At the zenith point of the closure wall 35 there is provided and connected thereto an abutment bar 38 which extends up to a transverse connection between the lateral driving frames 36 and 37 and forms a fixed connection between these parts. At the outer circumference of the closure wall 35, there is provided an upwardly displaceable cover 39 which extends from the bottom of the machine to the zenith point of the closure wall 35 and between the latter and the lateral driving frame 36. The cover 39 forms with a similar cover 40 on the other side of the can feed a closed cover for the can feed. The drawing shows the back side of cover 40 only partially. The drafting frame portion proper of the machine which extends between the lateral driving frames 36 and 37 is closed by a further cover 41 which is adapted to be displaced in a direction counter to the working direction of the fiber strands into an open position. The lateral edges of covers 39, 40 and 41 are similar to the other above mentioned embodiments inserted in guiding means, for instance into the guiding means 42 for cover 39. Also the winding device conveying the drafted fiber strands and the can receiving said fiber strand are enclosed in a housing-like manner.

Above the winding device there is provided an upwardly tiltable plate-like cover 43 which is tiltable about hinges 44 on the driving frames 36 and 37 and the lower closure edge of which rests on a frame which again is designed as guiding bar for two covers 45 and 46 extending in vertical direction and surrounding the receiving can 47. The

covers 45 and 46 have their upper edges guided in frame guiding bars 43 and at the bottom of the machine in a similar frame guiding bar 49. The guiding means are also in this case formed by simple grooves provided in the frame guiding bars 48 or 49 respectively similar to the guiding means 42 for the cover 39. In this way, it is possible to expose the textile technoligical working range wherever a manual operation has to be effected in the machine whereupon after completion of said operation the respective cover may be closed again. This is possible with regard to the can feed, the drafting frame proper, the winding device below the cover 43, and also the receiving can 47. Nevertheless, the operation of the machine can easily be observed because the transparency of the covers allows a proper observation.

The covers according to the invention are normally operable by the operator of the machine. However, if so desired, they may be actuated by mechanical or electric devices which may be drivingly connected with other parts of the machine, for instance with the controlling device for a certain supply length or control devices effective during a break of the fiber material. The illustrated embodiments show that a cover according to the invention may be adapted in any suitable manner to various types of spinning machines.
