I The object of' this invention isto provide a simple pneumaticcleaning apparatus adapted to be suspended or supported above a textile machine, such, for instance, as a spinning frame,

any suitable construction isafiixed tdthe'afore- (Gl.-15--20) 1 a said sleeve-shaft 21'." With this construction, it

will be obvious that rotation of the upright shaft 29 will cause a rapid rotation of the fan 28 to thus cause a downward draft within the fan-casand to travel back, and' forth over the top of the ing; At the bottom, the fan casing is shown 5 same while delive'ringa blast or blasts. of air divided into two spouts 29'which depend from V downwardly upon the machine to blow away the thefan-casing andv are curved around to bring accumulations oflint and dust while the textile their exit-ends to a point below the trough H3, so machine is in operation, as more fullyhereinafter that said blast will be delivered directly against Set forth I the parts of the textile machine to be kept. clean. In the drawings 1 A suitable air-inletis provided at the upperend Fig. 1 is a side elevation of our apparatus; of the fan-casing; r i Fig. 2 is an end elevationthereof; f Means are providedfor moving the aforesaid 1 Fig. 3 is a vertical cross-section on the line 3-3 blast-producing apparatus back and forth on the v of Fig.4; 1 f track it while the textile'machine is inbpera- 15 V Fig 4 is a verticalcross-section on th'e'line ll tion, this reciprocatory motion of the carriage of Fig.2; r g being derived from the continuous operation of Fig. 5 is a horizontal sectional view taken the aforesaid chain.

Within the trough of thechain. The end of the bar 3 pposite 'is mounted an endless chain H. which runs on the sprocket-wheel 34 furnishes a support for a sprocket-wheels l2,'the shaft i3jof oneof which Wheel 35 which is adapted to roll against the adextends downwardly and is adapted to be conjacent side of the trough.

"At the time.

, of thus reversing the bar 3|, the carriage stops,

will thus be seen that at each f'ndofthe travel ofthe carriage, the carriagewill first cometoa.

but the bar 3| continues its pivotal movement (on the shaft illas a pivot) until the sprocketwheel 3;} is "swung, over to the other side of the trough and put-into engagement .with the'other leg of "the chain, this being brought about by reason of thefact thatvth e pivotal end of the .rod' 36. is carried around the adjacent sprocket-1 wheel by the chaim This aetioniis snewn'm-idotted lines at the right-hand end-of Fig; 5.. It

dwell and then thesprocket-wheel t will be shiited o-ver from'one leg of the chain to the other, and then, after the.piv.0tal end of. thev rod 36 passes around the center of'the'sprocket 1 wheel, the reverse travel of the carriage-will take place, by which time the sprocket-wheel 34-.ihas been engaged withthe opposite leg of the chain and is; causing the fandriving shaft 2 8 to con; tinue the rotation which might have been momentarily stopped' during theshifting action of the sprocket wheel 34.1 If the speed of thef'appa:

ratus is sufficiently great; itwillbe observ'edltha't,

' there willcbepractically no stoppage of'the'fan during the reversal of the carriage travel, as this reversal" takes place veryjquickly' and it'i's probe able th'atthe-momentum of the driving-wheels will be "sufficient. toj'rcontinuethe action of] the fan during the shifting of the sprocket-wheel 354.

It will be observedthat' the fan we use is, of the disk type and that it is so arranged that it drives theair clearance between thec'hain and the sideof the directly downwardly toward the bottom 'of the casing. f'This, enables us to place the inlets of thetwo outlets 29 at the "bottom of the casing,
