6 Claims.

'This invention relates to a cleaning apparatus.

for textile machineryy such as spinning frames, drawing frames and the like, and more especially to that system which will direct draughts of air to all portions of the machine to remove lint and foreign substances therefrom.

Heretofore various devices have been employed for removing lint and other substances from textile machinery. It has been common practice to 10 direct blasts of air downwardly upon the creel board, drawing rolls, and thread board, of the spinning frames, and thereby remove the lint from the upper side thereof. The portions of the frames which were not subjected to the draughts 35 of air were not cleansed, and consequently the lint would cling to portions of the machinery below the thread board. This defect in cleaning is particularly noticeable in the lower portion of textile machines where many shafts, rods and cylinders are present to obstruct the downwardly directed draughts of air from the cleaner which is usually disposed thereabove.

It is, therefore, an object of this invention to provide a cleaning system for textile machinery comprising means for producing a plurality of draughts of air which are directed upon opposed sides of the members of the textile machine to thereby expose all surfaces to the necessary draughts for cleaning purposes.

It is another object of this invention to provide an apparatus for cleaning textile machinery comprising the combination of a travelling cleaner disposed above the textile machine for directing draughts of air downwardly, a plurality of fans disposed in the lower portion of the machine, and adapted to direct draughts of air longitudinally of the machine, and in the direction that the cleaner is travelling, together with a suction outlet disposed at the remote end of the textile machine for collecting the dust and lint removed from both sides of the textile machine, by the upper and lower fans. By locating one fan above the machine and another below, it is evident that the draughts from the respective fans will converge upon opposed sides of the members of the machine and thereby cooperate together in directing this lint to a suction opening, which will withdraw it from the room. This suction opening is partially assisted by the normal excess pressure within the room in whichthe textile machine operates. It is a well known fact that the pressure within thev room, under normal working conditions, is in excess of the outside atmospheric pressure, consequently there will be a tendency for the room pressure to force the room air into the suction opening and thereby supplement the work of the suction fan.

It is a further object of this invention to provide means for encasing the lower sides of spinning frames and the like and leaving air inlets at the top and bottom of the encasing means, and providing fans disposed within the encased portion of the machine for blowing lint from the lower portions of the machine, together with suction means communicating with the upper surlo face of the door beneath the machine, so that where travelling cleaners are used above the ma chine,` the lint which falls onto the iioor in the aisles will be drawn beneath the machine and removed by the suction means, and also the lint 15 which passes from the upper part of the machine, into the lower encased part of the machine, will be effectively removed from the portions of the machinery.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which- Figure l is a sectional view through the oor of a building showing in elevation a spinning frame embodying my invention;

Figure 2 is a sectional plan view taken along the line 2.--2 in Figure l;

Figure 3 is a vertical sectional view taken along the line 3 3 in Figure l;

Figure 4 is a schematic plan view showing the present invention employed in combination with a plurality of textile machines.

Referring more particularly to the drawings, the numeral i0 indicates the floor of a building upon which is mounted a textile machine such as a spinning frame I I, said frame comprising end frames |2, intermediate samsons I4, creel boards I6, sets of drawing rolls I1 and I8, ring rails I9, bolster rails 20, and cylinder 2|. 'Ihis cylinder is secured on shaft 22, the ends of which are journaled in end fra-mes l2. Suitable packages of yarn 25 are mounted on the creel boards from which it is drawn between rolls I1 and I8 in the form of strands 26, after which it is spun upon otherpackages 2l. Each package 21 is mounted upon a spindle assembly 28 which in turn is secured in bolster rail 20. Rotary motion is imparted to package 2l by means of a tape 3|, which tape is also mounted upon cylinder 2|. 0 I'he above enumerated parts are conventional, but it is deemed necessary to disclose this much of the conventional structure in order to more clearly illustrate the utility of my present invention. 55

As heretofore stated, the yarn which is being processed allows much lint and loose particles to be dropped therefrom and upon the framework of the machine. Some means must be provided for removing this lint in order to prevent batches of this lint from accumulating upon the framework and dropping into the processed yarns, and thereby create a defective product. 'Ihis lint has been removed with a great degree of success by a travelling cleaner such as disclosed in my prior patent, No. 2,011,763, issued on August 20, 1935. This patent discloses a cleaner casing such as indicated by 35. which has spouts 36 leading from the lower side thereof for directing blasts of air downwardly onto the top of the creel boards I6 and other portions of the textile machine. The casing 35 is supported by wheels 31, which are mounted upon

tracks

38 and 39, said tracks being disposed above a textile machine and supported by posts 40 which posts also support the creel boards I6.

By referring to Figure 4, it is seen that the trackway is continuous and is adapted to move over a plurality of spinning frames Il. As heretofore stated, it has been found that a cleaner such as shown on a trackway disposed above the machine fails to provide the necessary currents or daughts of air to remove the lint from the lower members of the machine. As a matter of fact the lower portions of the machine, that is, the portions disposed below the board 24, do not receive any draughts of air from the travelling cleaner; consequently the lint which once attaches itself to this surface remains in position until it becomes so heavy that it will eventually fall onto the floor or other portions of the machine.

In order to create the desired draughts of air in the lower portion of the machine, I have secured a pair of semi-circular bands 45 around the cylinder 2| at spaced intervals, each of said bands having a pair of fan blades 46 extending radially therefrom. When these blades are properly secured to the cylinder at the desired points, the rotation of the cylinder will direct blasts of air longitudinally of the machine and in the same direction as the direction of travel of the fan casing 35. It is seen that the fan in casing 35 will cooperate with the blades 46 on the cylinder 2| in directing the waste from the machine in a common direction.

The cleaning of the lower portion of the machine has been found to be much more effective when the lower portion thereof is encased. Therefore, suitable sideplates 48l haye been secured to the opposed sides of the textile machine, by means of screws 49, each side plate having a plurality of doors such as designated by reference character 50 secured thereto my means of suitable hinges 5I. 'I'he upper edges of the doors 50 are adapted to abut against a longitudinal strut 53 and are held in a latched position by means of suitable latches 54. The lower portion of the side plates 48 have adjustably se- 'cured thereto a plurality of plates 55 by any suitable means such as screws 5E. The screws 56 penetrate slots 51 in each end of these plates and hold the lower edges of the plates a short distance above the floor level. 'I'his provides a slot 58 through which the dust and lint which has fallen upon the oor and in the aisles between the machines may be drawn by the suction created by a fan 60. The fan 60 has an inlet pipe 6l leading therefrom which is connected to opening 62 in the :door HI. When this fan is in operation the air is drawn from the opening I 62 and through the fan from vwhenceit is expelled through its outlet 63.1 The action of thevv fan 60 is supplemented by the normal excess atmospheric pressure within the room during the period that the machine is in operation, and this normal excess pressure helps tofdirect the lint to the opening 62. When it is desired to dofl!v packages 2l it is only necessary to unlatch the doors 50 by operating the latch 54 after which the door can be rotated to dotted lline position as shown in Figure 3. This not only will allow the packages 21 to be dotted but will alsoy serve' to give access to the lower portions `of the textile machine.

In the drawings and specification there has been set forth a preferred embodiment of the.

machine from a point substantially level with,

the roll stand board to within a'. short distance of the bottom of the machine, a plurality of fans mounted on the cylinder for creating drafts of air moving towards one end of the machine for removing lint and other particles from the portions of the machine disposed below the roll stand board, and suction means communicating with the interior of the machinefor withdrawing removed lint from beneath the machine and for creating an inwardly moving draft from the exterior of the machine to the interior thereof through the slots appearing below the lower edge of the encasing means to thereby cause lint and other particles on the floor adjacent the sides of the machine to be drawn beneath the machine and into said suction means.
