This invention relates to a traveling cleanmg device for stretching or delivering mechanlsms of spinning or twisting machlnes, 1n

which a cleaning brush situated with its axle at an angle to the axle of the upper cylinder, automatically glides over the stretching or delivering mechanism. l

It is known to arrange a conicalcleaning brush on two upper cylinders to clean the l0 stretching mechanism cylinders-and to guide this cleaning cylinder by a frame surrounding the same and resting on the upper cylinder. In order to prevent the frame from dropping out it extends in curved-shape around the rear upper cylinder and in order to prevent the cleaning cylinder from dropping out of the frame, the frame is provided with two angle supports, on which the journals of the cleaning brush slide.

It is also known to make such a cleaning brush in double conical shape and allow the same to rest with one cone on three cylinders so that it receives; an inclined position and consequently slides longitudinally over the cylinders of the stretching mechanism.

The known cleaning devicesk can however not be employed onthe delivery mechanism of a two-cylinder spinning machine and on drawing stretching mechanisms.

This invention has for its .object to produce a suitable cleaning device for such spinning machines. With this object in View a conical or'cylindrical cleaning brush is, according to the invention, arranged on the 85 front upper cylinder at an mgle to its axis and mounted in a frame shiftable longitudinally on rear guides, for example on the rear uppercylinder or on the rear thread guide.

To enable this arrangement to be also em-' 40 ployed on already existing stretching and delivering mechanisms, without altering the same, the frame, if guided on the rearupper cylinder, is slightly bent, but, in order to prevent it from dropping out, is provided at the rear with a special counterweight. In order to be able to clean the middle drawing upper cylinder, a special cleaning brush may at the same time beI arranged on the frame. If, however a cylindrical cleaning brush is chosen, it is mounted in a. forked'element,

oscillatable through 180 in the rear guide element, so that it can be adjusted to the most suitable position, according to the direction in which it is to automatically travel. The guide element or frame, in the case of two-cylinder carriage spinning machines, slides over the known bow-shaped thread or slub guides and for this purpose is made in inverted V-shape.

If it were desired to mount the frame orthe forked element of the cleaning brush, for example on a continuous guide rod, in the case of two-cylinder carriage spinning machines, this would notbe possible, because it is necessary to insert the slub between the forked thread or slub guides about every two hours. However, as already mentioned, it is desired to enable the new cleaning device to be employed on existing arrangements without alteration.

Two embodiments of the invention are il` lustrated by way of example in the accompanying drawings, in which:

Fig. 1 shows in side elevation the employment of a conical cleaning brush with a fourcylinder stretching mechanism,

Fig. 2 is a front elevation of Fig. 1,

Fig. 3 is an end view, seen from the right of Fig. 4, l

Fig. 4 is a front elevation, showing the employment of a cylindrical cleaning brush with a tvo-cylinder carriage spinning mechanism an Fig. 5 is a top plan view of Fi 4.

The cleaning device consists 0% a frame 1, in which the cleaning brush 2 is journaled and which is moved by the cleaning cylinder over the stretching cylinders in axial direction thereto. 3, 4, 5 and 6 are the stretching cylinders in a four-cylinder stretching mechanism. The stretching cylinders are mount-` ed vin the cylinder support 7, fixed on the cylinder bank 8. The frames 1 is providedl with runners 9, 10 with which it slides on the rear stretching cylinder 6. These runners must 95 be at least so long that they bear on two juxtaposed cylinders 6. Their ends are preferably bent upwards, in order to enable an easy transition from one cylinder to the other. In order to 'prevent the frame from dropping 100 olii' thecylinder 6, that is, to ensure a reliable bearing, one of the runners is provided with a counterweight 13.

A cylindrical brush 14 is mounted in the frame 1 and receives its drive from the inclined cleaning brush 2, for example through the intermediary of a cord or belt drive 15, 16. This brush serves for cleaning not only the cleaning brush 2, but also the upper cylinders 5 and 6. The material, which the brush 14 takes from the cleaning brush and the two upper cylinders 5 and 6, is collected in an upwardly oldable comb 18, movably mounted in a frame 17, from which comb the material is easily removed, when the cleaning device arrivesat the end of the machine.

One of the arms carrying the weight 13 may be provided' with a brush 19, by means of which the upper portion of the carriage 20 can be cleaned. The material taken up by the brush 19 is held in a piece of card clothing 21. A removable cover 22, lined for eX-' ample with plush on the side directed towards the upper cylinder 6, may be arranged on the two runners 9 and 10 of the cleaning device for the purpose of also removing dust.

The free end ofthe axle 14al of the cylindrical brush 14 may be provided with a wheel shaped brush 25, by means owhich a further portion of the carriage 23 and the screws mounted therein can be cleaned, whereas the drawing cylinder 4 is kept clean by a brush 26 adjustable in height.

Finally one side portion 1a of the frame 1 may be provided with a resilient wiper 28, for the purpose of subsequently cleaning the leather-lagged stretching mechanism cylinders 3. By means of this wiper the upper portion of the weight hook 29 will also be simultaneously cleaned. d

When the stretching mechanism and the cleaning device are in operation, the latter moves in the direction of the arrow m (Fig. 2) it is raised at the end of the machine from the two upper cylinders 3 and 6 and placed on the other side of the vmachine on the stretching cylinders, after which it moves in the opposite direction, and on reaching the end of the stretching cylinders, is again placed ,on the upper cylinders and thus continually circulates.

In `the form of construction illustrated in Figs. 3 lto 5, the cleaning brush 2 is cylindrical and is mounted in bearing slots 30 of a fork 31, and bears on the upper cylinder 3 of the stretching mechanism. Fork 31 has a pin 33 mounted thereon extending nearly perpendicularly to the axis of cylindrical brush 2. Pin 33 may be changed in position in a guiding frame 32 by 180 b v removing the fork 31 from the machine and re-inserting pin 33 with the brush and supporting structure in reversed position. On bows 34 arranged in a common bar 35, the element 32, bent in inverted V-shape, slides like a rider,` the ends of this element being slightly bent over outvardly, in order to ensure a reliable transition from one bow 34 to the next without jamming. The pin 33, mountedin the guiding element 32 approximately perpendicularly'to the axle of the upper cylinder 3, is bent at an angle so that the fork 31 extends with the brush 2 at an angle to the axle of the upper cylinders. -When the cleaning device, consisting of the parts 2, 31, 32 and 33, reaches the end of the machine, the automatic return of the cleaning device is started by swinging the fork 31 withl the cleaning brush 2 out of the position shown in Fig. 5, into that indicated by the dot-dash line afi-y.'

It is evident that such a cleaning device can be employed not only on spinning and twisting machines orworking cotton, but also on machines for any other fibrous material.
