'liextile machines naturally will become covered with dust in operation. Preferably the most essential drive members of the machine, which are assembled in the drive head, should be hooded to the outside as fully as possible. A complete enclosure or sealing of the drive head, however, is not possible since the said head is operatively connected with the machine proper and certain members which translate the movement have to be adjusted slots provided in the cowling. As the rotating machine members produce air currents. the ingress of dust and fiy through the apertures present in the cowling is undesirably increased.
The method according to my present invention eliminatesthe said deficiencies in that the air in the hooded drive head of the machine is subject to a pressure higher than the atmospheric pressure. Air thus will constantly flow to the outside through the apertures in the hood. Dust and fiy. thus, is prevented from reaching the inside of the hooded machine drive-head, and, further, the drive-head members which besome heated by friction are constantly cooled by air, which feature is very desirable. The said protective and cooling features contribute a great deal to a reliable operation of the machine, and, further, the maintenance of the latter is facilitated.
A ran, advantageously mounted inside the hood on a drive shaft of the machine and which sucks the air through ascreened opening in the hood, niitablyisusedasameansforraisingtheair pressure inside the hood.
The method according to my present invention is explained, by way of example, by means of the partly schematic drawing which illusirates one example of the means for carrying into elect the said method, which means also form part of my present invention.
In the drawing, the drive head of a spinning machine is shown in vertical section.
The hood comprises a sheet member I which covers the machine drive-head on the end face and on top, and which is secured on the machine side to the end shield I of the spinning frame and, on the rear side, to a rear wall I,'the front wall being omitted. An electric motor 4, disposedinthe drive headmamanner knownper A fan II is secured to the overhung end of the main shaft I inside the hood. in close proximity to a suction opening in the end wall of I -spinning process.
When the spinning machine is in operation, the fan It secured to the main shaft 8 is rotated and sucks air through the screen ii from the outside into the drive head so that a slight excess pressure is built up in the hooded head. The air escapes from the latter through all the openings where moving members or the machine pass through the hood, for example, the slots where the rolls i2 and the drive drum it pass into the hood.
The excess pressure in the machine drive head is built up to such value that the air flows out of the hood at moderate velocity so as not to impair the spinning operation. Such pressure, however, is sufilcient to positively keep out all impurities from the machine members inside the drive-head hood.
What I claim as new anddesire to secure by Letters Patent, is:
1. Apparatus for preventing the settling of dust and waste on the driving heads of textile ma- .c-hinery, comprising a casing closing ofi said operating parts of the driving heads from the outside, said casing being provided with openings for the passage of power transmission members for driving the textile machinery, a fan in the space enclosed by said casing, a drive shaft for the fan said casing having an opening for ingress of air, an air filter covering said air ingress opening, said fan being located adjacent said air opening for drawing air through said opening and filter into the casing under a pressure higher than atmospheric so that a continuous outflow of air will take place from the shaft openings in the casing so as to prevent dust and waste from entering the casing.
