This invention relates to cleansing apparatus and more particularly to such 4apparatus in yconnection with certain portions of paper-making machinery which tend to be` and flexible means of control to meet varying conditions of use. Another object is to provide apparatus of the above nature inwhich the wear of the parts is reduced to a minimum. Another object is to provide a simple and highly eificient reversing mechanism. Other objects will be in partobvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, `combinations of elements, and arrangement of parts as will be exemplified in the structure to be hereinafter described and the scope of the applicationl of which will be indicated` in the following claims. V

In the accompanying drawings in which is shown one of various possible embodiments of this invention, I ,Y

In order that certain dominant features of this invention may be the more readily .y grasped, it may be noted that in paper-makV ing machinery there are pulp-supporting elements of the machine which tend to become clogged `with pulp andV introduce imperfec- APPARATS 192s. seri'ai- No. 290,763.

tions in the resilientfpaperl 'L Thisclogging kmay occur at various portions of the surface Vand to varying' degrees; furthermore, there isa continuous tendency to clogging even though it does not become localized. l, Itis `also to be noted that in machinery of this sortthe space available for cleansing mechanism is cramped and the'conditionsof use are severe. y To provide apparatuswhi'ch will efficiently meet these severe requirements and l' perform its functions in a practical and dependable manner is amongthe dominant aims of this invention althoughit maybe noted that Acertain features herein setff'orth areyof advantagein other relations..

1 Referring now in detail to ing drawings, there is diagrammaticallyindicated` in Fig. "2 at110 -the element to 'bev cleaned, which maybe a screen, felt or other form, andwhich may be assumedto travel in a direction toward or away .from the paper,

still having reference to Fig.12. i Mounted above theelement 10 isa casing`11whichv Y may be supported in anyj convenientrnanner and which is providedrwithtight end ttings 12 and 13 'respectively'.` Journaled withinv these fittings is a threadedvshaftlll ,one endy lof which is driven throughsuitable. reverse mechanism, hereinafter, `described 'in detail, `from a pulley .15, a aw' clutch 16 being provided to throw on and oi'power, this clutch being controlledbya sliding rodfl? having a handgriplS. i f Mounted upon shaftllill and/.having ,an inlternal thread coacting therewith is asleeve 19 having anintegralarm 2O extending later# ally through Va slot 21 inv the l'casing 11, asbest indicated in Fig. 5 of the drawings. This slot 21 extends throughout a substantial por.-V

tionl of the length of casing 11 and leadsy 99 `through a registering slot v22 in a supplementov simiy sideof the upper portion 11. This vcasingfl `is provided at its bottom with a slot24 subtary casing `23 'secured'asby brazing tov one stantially coeextensive vin lengthv with the 95 slots ,21 and`22. y The arm 20 'terminates in aiitting 251lead- Y ingI into whichlandsecured to which is one x end of apipe 26 -whichis connected at its4 op.- posite end'with'ja hose 2f?.

The hose 27 is provided With suitablev slack and leads upwardly over the roller 29 as indicated in Fig. 2 ofthe drawings and under the roller 30 placed somewhat in advance. of the roller 29. Engaging the hose onthe sides are a'pair ofrollers 31 elsindicated in Fig. 1 j and it Will thus be seen that as the hose travels into and out of casing 23 it rides upon these slightly c oncaved rollers thus lessening the load on 'the` moving parts and greatly reduc- 'ingthe Wear upon the hose.,

as hort'dischargetube 33 having at its end a nozzlef34 provided with a flat slot 35 which i V"ertends in the direction of the length' of ther casing 23.

'- It'willthus be seen that in all positions oi y"the sleeve 19 along the threaded shaft 14 i the 'fitting 25 will readily Vassumea corre'- l sponding position andV carry With-it the fluid Vjet from the nozzle 34. v

thatthe :term 'jet.` is used vthroughout in aV broadfsense to indicatea-ny form'of discharge f f of aV cleansing iiuid and that the term fnozzle is used With Van equally'broad significance 'to denote any partfrom ulrhichajet may be 1j It may here be noted discharged.

' i' power beingrapplied to'theshaft 14 its rotationY Willmove the nozzle 34 across thesurface of the part 1O,'Atl 1e"direction of movement being governed by the direction of rotation of the shaft. There `is accordingly' Yprovided reversing mechanism `whereby the nozzle may beicaused to move baclrand forth across the part to be' cleanedfwithout thel necessity for :reversal of thedriving mechanism. On the drivenfsideof the clutch16 is a shorthollow Shaft section 36 which' terminates in a beveled pinion-37 having formed v thereonfa javv; clutch member :38. A Mating with pinion is abeveledpinion 39 whichl may be mounted upon ast-ud shaft -40 extend-` ing froin thefv inner surface of a connecting portion 41 which is vpreferably cast integralv withthe fittingsi13 and 49.V This .unitary ar- Thepinion 39V drivesfa beveled pinmember 45 splined to the shaft 14 and'adapti .if edito be slid along thatsha'ft vWith either of them..

"A pali" of spiralsprings 52 and 53 rest about the shaft 43 betyveen the revsp'ective c nds Vof the lhub 51 andthe correspondingends of the support 47. f Thus as the actuating member 50 is moved to the 8 0V left or -tothe-right having-reteren'ceto Fig.

This rod'isVjr Witha pair er stops 61 :and 62ad .heldthcrcon'by setscrews or others` ble l formed on the sleeve 19. Thus, assuming that the direction of drive of shaft 14 is such as to move the sleeve-19 to the left, having reference to Fig. 2 of the drawings, the shoulder 63 will engage and move the stop 61, and by the means hereinbefore described actua-te the reversing mechanism to reverse the direction of drive of the shaft 14. Thereupon the sleeve 19 will travel toward the right, having reference to Fig. 2, luntil the shoulder 64 engages and moves the stop 62 thereby again actuating the reverse mechanism and again reversing the direction of drive of the shaft 14. -In this kmanner the ysleeve 19 automatically and positively travsubstantially no wear on the parts and no A apparatus which theseveral objects of this i mad-e of the above invention andas many i GO uncertainty of operation. The threads on .the shaft 14 may be of any'desired size, and

the internal'threads meshing therewith h ave a continuous snug fit. Furthermore, the

mounting of the hose relieves his part of any l substantial .load and there is no interference with full lubrication of the shaft and its associated parts as there is no leakage of water from the casing 23 to the casing 11.'

In the use of apparatus of this nature often happens that there is an aggravated clogging of the web at some particular part, and it is possible that with an ordinary regular back-and-forth movement of thejet this clogged portion may be carried past vthe line of cleansing before it is engaged with suffi- -ci'ent severity by the cleansingr fluid. Thisk is provided for bythe hand control through the grip 60 of the controlling rod 59. By a slight longitudinal movement of this vrodv bv hand the reverse of the shaft 14 is effected at any time irrespective of the position of the sleeve 19 with respect tothe stops Gland 62. Thus the nozzle and cleansing jet may be Caused to reverse their direction of movement at any desired instant and may be made to move back and forth quickly through a path of any desired lengthorpositi'onj to meet the particular'conditions which are confronted. l y

It will thus be seen that there is provided .invention are accomplished and which is well adapted to meet the conditions of hard practical use. Y
