3 claims. (01.104-49) This invention relates to apparatus for cleaning machines and more especially to cleaning textile machinery by providing a suitable travelling blast producing means to travel on a trackway disposed directly above the machinery or on a trackway disposed between rows of machinery for blowing from the machine lint and other particles to prevent the same from becoming a part of the yarn or other textile products being manufactured or processed on the machine.

It is an object of this invention to provide a trackway disposed above parallel rows of machines or between parallel row of machines for the reception of a travelling fan. Instead of havi5 ing the trackway continuous, which is sometimes objectionable, on account of the return bends of the trackway obstructing passageways, I provide means whereby, when the traveller reaches an end of a trackway, the same will be transferred automatically by swinging the traveller through a semi-circle to present it to the end of another trackway, which is usually parallel to the first trackway.

It is another object of this invention to provide a plurality of trackways for the reception of a travelling fan with means for automatically transferring the travelling fan from one trackway when it has travelled to the end thereof, to the end of the other trackway, so that the travelling fan will proceed to travel over the lnext adjacent trackway, and when the travelling fan reaches the end of said next radjacent trackway, similar means are provided at the end thereof for automatically transferring the travelling fan tothe trackway from whence it was removed in the rst instance or to transfer said fan to another-track- Way. In this manner, the advantages of an endless track are obtained, and yet the return bends of the continuous track are eliminated and thus prevents the aislesv in a cotton mill from being obstructed by these return bends running from one row of machines to another.

Some of the objects of the invention having been stated, other objects will appear as thedescription proceeds, when taken in connection with the accompanying drawings, in which:

Figure l is a top plan view of a portion of two parallel trackways and kshowing my invention in connection therewith;

Figure 2 is a side elevation looking from along the line 2 2 in Figure 1;

Figure 3 is a side elevation'similar toFigure 2,

l but taken along 'the' line 3 3 inFigure l, and showing the dotted portion appearing'in Figure 1, in full lines;

Figure 4 is a vertical elevation, partly in s'ection, taken along the line 4 4 in Figure 1;

Figure 5 is a View largely in side elevation but partly in vertical section and being taken along the line 5 5 in Figure 4;

Figure 6 is a vertical sectional view taken along the line 6 6 in Figure 5;

Figure 7 is a top plan view with parts in section taken along the line 'I I in Figure 5;

Figure 8 is a view showing one end of the trackways andtaken along the line 8 8 in Figure l, but showing the lever at the left-hand side thereof in elevation.

Referring more specically to the drawings, the numerals Ill and I I indicate rails forming a trackway disposed either between and above parallel rows of machines, or directly above the rows of machines and supported in any suitable manner either from the ceiling of the building, or from supports I2 extending upwardly from the floor or from the machine. These supports I2 have cross pieces I3 which support the tracks I0 and I I, and also support a trough Ill having insulating blocks I5 therein in which conductive wires I5 and I'I are mounted. These wires are adapted to be contacted by brushes I8 resiliently mounted in collar I9 in a traveller and normally pressed into contact with the conductive members by meansvof a compression rspring 20, (Figs. 3 and 4'); The

4 traveller has a main inverted U-shaped frame ZI eled gear 28 meshing with a bevel gear' 29 mounted on the lower end of a vertically disposed shaft 30 on whose upper end is fixed a worm gear 3l which has contact with a worm 32 mounted on motor shaft 33 of electric motor 34, (Figs. 2 and 3). Motor shaft 33 has a pinion 35 Ythereon which meshes with a pinion 36 on ashaft 3l mounted in bearings 38 and 39, and on each end of this shaft are suitable disk fans which are surrounded by casings 43 and 44 having leading therefrom ducts 45 and 46 which extend out-v wardly and then'downwardly for directing blasts of air from the disk fans onto the machinery to l remove the lint and other foreign particles therefrom as the` traveller moves along the tracks.

Ity is thus seen that motor 34 derives its cur- 35 tending end of shaft 25.

- rent from the conductive trolley members I6 and I 1 and propels the traveller along the tracks and also imparts rotation to the two fans for creating the blasts of air.

5 Trolley members i6 and I1 receive the current from leads 48 and 4I, said leads being connected to a suitable source of electrical energy.

AWhen the traveller has reached the ends of tracks I6 and II, it proceeds to travel onto a 10 turn-table mechanism for transferring the traveller to the end of the next adjacent trackway. This turn-table apparatus comprises a shaft 58 which is shown as being secured at its upper end to the ceiling 5I of the building in which the apl5 paratus is installed, though other points of support might be preferred. The shaft 5| has turnably mounted therearound a sleeve 52 on whose upper end is i'lxed a grooved pulley 53 and `on' Whose lower end there is a boss 54 to which is secured a U-shaped member 55. Fixed on shaft 50 is a lug 58a which has secured thereto a supporting arm 56 for supporting a grooved idler pulley 51. A cord is attached as at 58 in grooved pulley 53 and passes over idler grooved pulley 51 and has a weight 59 attached to the lower end thereof. Shaft 58 which is fixed to the ceiling or any other suitable support has xed on the lower end thereof a beveled gear 6I which is adapted to mesh with a beveled gear 68 fixed on shaft 62 which is mounted for rotation in lugs 63 and 64 projecting downwardly from U-shaped member 55. The outer end of shaft 62 has a gear 81 secured thereon which is adapted at times to mesh with a gear 68 mounted on the outwardly ex- The member 55 has mounted on the upper side thereof tracks I6 and 1I together with a trough 12 with insulation blocks 13 and conductive members 1A and 15 therein similar to conductive members I8 and I1.

Track I0 has projecting therefrom a pin 86 which is adapted to be engaged by the hooked end of lever 8l mounted on pin 82 on the outside of track 10. Track 10 also has a pin 83 extending therefrom, the purpose of which will be presently described.

One of the arms of member 55 has a projecting portion 84 mounted thereon to which is secured member 85 in which is pivoted a cam lever 86 and to one end of cam lever 86 is pivotally connected a rising bar 81 which projects upwardly and in the position shown in Figure 2 is disposed in the path of a projection 88 secured on framework 2I. The left-hand end of lever 86 is beveled and is heavier than the other end and causes the parts to normally assume the position shown in Figure 2. The adjacent trackway is similar in all respects to tracks I0 and I I, and the tracks thereof are designated by reference characters IDa and IIa. The other parts associated with tracks Illa and IIa are identical to the parts previously described in connection with tracks I0 and II; therefore, like reference characters will be given like parts.

Track Illa, near the left-hand end thereof, as

shown in Figure 1, has a lever 90 pivotally mounted intermediate its ends having a cavity therein and having a leading sloping end adapted to ride over pin 83 and to lock the turn-table to tracks Illa and Ha. when it is moved to ythe dotted line position as shown in Figure 1. Track Illa also has projecting downwardly therefrom member 9| having a rod 92 therein adapted to engagethe leading cam end of lever 86 to move the Asame `to the position shown in Figurev 3, so as to allow the "traveller to move onto the tracks Illa and I Ia when the turn-table has swung to the position shown in dotted lines in Figure 1.

The structure shown at the upper right-hand corner of Figure 1 is identical in all respects to that shown at the lower left-hand corner of the same Figure, and similar reference characters apply.

Method of operation Let us assumer that the traveller is travelling along tracks I8 and II. When the front wheel 21 rolls past lever 8|, it will not move the same, Y because the wheel does not extend outwardly far `enough. However, as the traveller progresses,

the pinion 68 engages the pinion 61 and the pinion-'68being driven by the motor, begins to move upwardly onto pinion 61 to the position shown in Figure 2. The projection 88 having come into contact with uprising bar 81, prevents forward movement of shaft 25. In this position, lever 8I is released from pin 80 by wheel 23. 'Shaft 62, on laccount vof'having its bevel gear 66 engaging a fixed bevel gear 6I, cannot move, and this results in the pinion 68 moving upwardly on top of pinion 61 until the parts reach the position shown in Figure 3. The pinion 6I being fixed to shaft 56 therefore causes rotative movement of grooved pulley 53 asy pinion 68 travels on fixed pinion 6I and winds the cord onto pulley 53, and moves the weight 59 on the lower end thereof upwardly to store up energy.

In order to supply electric current to the mechanism, while it is being swung from one track to another, suitable current supplying means must be employed because thetraveller will be disconnected from the conducting wires on the trackways. One form of supplying this current is shown in the drawings in which a drop cord 95 passed downwardly and beneath shaft 62 and upwardly to where it is connected to contact posts 96 and 91 passing downwardly through an insulating block-13 and being insulated from the trough 12.

When the parts have assumed the position shown in Figure 3, and rotation of shaft 62 is begun, and current is supplied through drop cord 95 to the electric motor, the traveller does not travel on the tracks 10 and 1I, but shaft 62 is rotated. On account of this shaft'engaging the non-rotatable bevel gear 6I, the turn-table is swung around to the dotted line position shown in Figure l where it is latched to tracks. Illa and IIa by members 83 and 90, and movementof the turn-table being stopped, and the rising bar 81 being removed from the path of member 88 by contact of members 86 and 92, the traveller moves on over the pinion 61 until its front wheels come into tractive engagement with the tracks d on the turn-table. Then the traveller moves onto the tracks Ilia, and II a and traverses Athe length of these tracks, which in many instances will be several hundred feet long, and rides onto another turn-table at the far end of the tracks Illa and IIa, which is identical in all respects to the turn-table described. At this time the turn-table is swung around to the other end of the tracks IIJ and II in the same manner as that described in the previous swinging operation.

When the traveller rolls onto tracks Ia and IIa, lever 90 is caused by wheel 23 to disengage pin 83 and the weight 59 returns the turn-table tothe full line position shown in Figure 1.l .A A

In the drawings and specification there has been set forth a preferred embodiment of the invention, and although specific terms are employed, they are used in a generic and descriptive sense only, and not for purposes of limitation, the scope of the invention being set forth 5 in the appended claims.
