H Referring`more particularly to the drawings,

` preferred embodiment ofthe invention, 1 designates the base of the apparatus having thereon a conveying means for engaging a rug, hereinshown in the form of a pair of feed rollers, 2,1 3;a beating means` generally indicated at 4; a Ivacuum cleaning means 5; and a brushing `means, herein shown inthe form of a pair of rotary brushes, 6, 7. The basel is provided with suitable upstand- .jingy portionsI 8,- 8`1at each side of the machine which" form the framework for t A'horizontal plate portion-9 on the base extends betweenithe upstanding ,portions 8,` 8 and supports on its upper surface a pair of angle castings 10 and 11 which supporting the are suitably secured centrally on the plate portion r y 9.with their adjacent vertical portions 12 and 13 somewhat spaced apart to form the throat pore tion of the vacuum cleaning means which willbe described hereinafter. i

.r For =the sake of convenience of reference, the

right hand side of the machine as seenin Fig. l will be referred to as the front and theleft side `the rear of the machine.

The feed rollers, beating means and `brushes are` disposed 1 transversely of the machine b etween the upstanding frame 4portions 8 8. It is desirable that the corresponding feed rollers and brushes be arranged for `movement toward and from each, other for the purpose of facilitating starting of the rug between the rollers and determining the pressure of the brushes upon the rug.,` In the present embodiment the lower roller and brushare stationary on the frame l, and

the .upper roller` and brush vare vertically movable.

The lower roller 3 is mounted on a shaft `14 journalled in bearing brackets 15 whicharebolted or otherwise secured to the angle castinglO.

The upper rollerA 2,`theupper brush 6 and the ment is mounted on a beam member which extends between the slides 16-and is-.secured atbeating means 4 are operatively supported between vertically movable slide members 16 guided between pairs of inwardly extending lugs 17 on the upstanding portions 8, 8, see Fig. 3. The roller 2 is supported on a shaft 18 journalled in the slides 16. One end of the shaft extends outwardly of one of the frame portions 8 through a slot 19 formed therein land is provided with suitable gear means, hereinafter described', for driving the roller. e

The rollers 2 and 3 may be of any suitable con'- struction and are provided with any suitable friction covering such as rubber or lcloth to enable them to engage and feed the ruginto the machine;

A suitable adjusting meansginfthe present in'- stance indicated 'bjy an adjusting nut ,31, pro'- vided for decreasing orf increasing the' distance between the cross rod Eiland' the'impact ro'd 2.9.

,Thebeating tool may' b e operated in 'various ways ,to deliverimpacts to a rug therebeneath, 'but' the'present `embodiment theoperating means is shown as a camshaft' 32 extending along the beam` 2O and journa'l'ledin each pair of arms 23 on' brackets 22 and'which supports cams 33 thereon arranged for"altern'ate lifting or releasing Yofv the beating tools. A roller 34 is-providedfon each cross' rod 30 and is positionedy soas tofbefengagedby the' cam'in' its rotation with shaft 32. A coil spring 35 surrounds 'the lower end orffthe 27Nand theupper sident the head y'to cause the `head 28 to move downwardwhen the-cam passes from engagement with roller 34. Referring "A1-twill' be seen that when the calm) 33 is rotate finfthe direction shown by the arrfwfit will engage roller SLi-and'thereby lift thebeatingtool-'against the tension of' the springs 35V and, upon further rotation of' the camfi-twill pass-from engagement with the roller and allow the springs to-force'l the 'gtool downwardly, thus causing-it'to deliver-'a' sharp impact against the rugytherebeneathto eiiecti-vel-y Aseparate' the dust tlffereffrom.V

ff.'1fle anisfnvrnayallbe secured in the same position lon .shaft 32, kif desired, but it has been found'p'referable to arrange the cams on the shaft in .varyingy angular positions (see Figs. 1 and 4) so' that the adjacent beating tools will not operate simultaneously. ff'fhe .cams may also be arranged so' that no' two beating tools will operate at the same time'. The' particular sequence of operation,-

however,` is notmaterialto the present invention. 'Y Means are provided for yieldably supporting therujg at the point where the beating tool strikes. It is desirable to so correlate the yielding supportin g means'fwth the' 'beating tool. that when the tool strikes the" rugtnere' will be animpaet which rods-26 jandbueer against the lower side ofv bosseswill tend to remove the dust and after the impact the tool will continue to move downwardly so as to ilex or bend the rug at this point thereby opening the weave to loosen matted dirt from the interstices thereof. It is also desirable that the yielding supporting means be arranged so as to hold the rug, or a portion thereof in an upwardly iiexed position when the beating to'ol is not in engagement with the rug'. In. connection with the supporting means above described it has been found preferable to provide a vacuum means to vact on the rug at the time of the exing operation. The' above mentioned functions may be carried-out by various forms of mechanism and the flexing operation may or may not be accompar-liedwith Aa beating operation in order to produce desirable results upon the rug or other fabric.

, .1n-the present embodiment of the invention the yielding supporting means for the rug is positioned within the lthroat portion of the vacuum cleaning meansv 5 and 'these structures' will, therefore, be' described together. -As'sta'tedabov'e, the' angle Icastings 10 and 1l are positioned onthe plate portion- 9` with' the' upstand-in'g-portions `1'2 and 13 adjacent' and spaced apart. vIlie'upstanding portions thus form part of al throat' ortlfe vacuum means. lBetween the langle casting's' 10 and 11 the horizontal plate portion 9 is formed' with an opening into which a -neck`36 of a vacuum chest 37 is iittedas shown in Fig. 5. On' the upstanding vpart 12 is secured a bracket member 38 which servesalso as a-continuation of one side Eof the vacuum throat formed by parts 12 and i3'. The bracket member 38, in the present instance', extends toward the rollers' 2 and 3 and has an integrally formed plate portion 39 'extending-forward-ly toward -the beating mechanism.' The plate 39 serves to supportv the rug immediately after passing 'from the rollers 2 and 3 and 'before it is engaged by the beating means. Wh-ile' this plate can be horizontal or' inclined in''either direction, in the preferred' form ofthe inventionit is inclined upwardly toward the beating means as shown in Fig. 5. A somewhat similar plate portionr to the plate 39 is formed' on the upstand'- ing part 13 ofthe angle casting 11 serving both as a part of the vacuum'throat' structure and as'a supporting means for the rug.V Thisis shown in the yform of an` angle bracket-having a depending part 40, bolted or otherwise attached'to partf13, and a surface .41 which projects toward the brushes GVand 7 and serves toA supportl v'the rug after itileaves thebeating means -until `it passes between the brushes.

The yielding supporting means is shown in the present instance in the form or a 'plurality of lengths of coiled springwire 42 which are supported vat"the (entrance''oflthe vacuum throatformed between the adjacent-'edgesv ofy plates V39 and 41'.I -The l'englthof the 'coilsof wire'is preferably the same as the length of the beating tools',` see Fig. 4..

Means are provided for yieldingly supporting the coils or springs 42 vfor vertical movement vwithinthe vacuum` throat. The means preferably comprises a plate 43 pivoted at 44 on the bracket 38 held in position-by a spring 45 so that the free edge of the plate contacts the lower part of the coill spring 42 and holds the upper surface of the coil spring normally somewhat above the adjacent edges of plates 39 and 41. It will be understood that the pivoted plates 43y substantially. correspond in length to the coil springs and the beating tools,

The cams 33 are rotating at considerable` :speed vthusalternately moving the beat-V ing tools up against the; compression of their springs 35y and .allowing lth'em-to-move` quickly downward when the cam passes out of contact with the froller 13,4. :.,Each beatingtool produces airapidisuccession of sharp impacts upon the rug immediately above its companioncoil spring 42.

s already explained, the beaters preferably do notoperate inunison, but are operated in 'any predetermined.sequence. The result being that Y the rugreceives a quick succession of independent l inra suitablemanner..-y

impacts transversely of its -length `as it is -moved along byrolls 2 and13 and brushes 6 and '7:`

' When-'the beating tool strikes the rug opposite coilispring -42 it produces nrst a relatively sharp impact and afterward-asn overcomes the in ertia ofthe` coil, itgcauses'downward movement of the same within the vacuum throat to thus bring-the rug vto a downwardlyflexed condition. After the beaterl head' moves upwardly, the spring 45 forces the plate 43 .upto its position as shown in Fig. v5 and theplate in turn Aforces the coi-lxspring 42 up to the position shown in the samegure. It is apparent that the action of the .beater is Eto nrst give rthe'` rug -a sharp blow after which the rug is moved from an upwardly flexed -to a rdownwardly flexed position. This movement Vtends ,to `separate the Vfibres very thoroughly and loosen the dust thereinI so asto facilitateitsgremoval by the vacuum means.

.fThe dust `and dirtv loosened by the beaters passesr between springs =42 down throughthe vacuum throat and into .the vacuum chest where it may be collected After the rug leaves thejbeater mechanism it -passes :along the surface 41 and between the brushes 6 and .7 whereany remaining dirt and dust onithe surfaces ofthe rug isremoved and conducted through the `openings -76 and '77 to the vacuumv chest. When the rug has `passed through Ithe machine the .slide 22 is raised :preparatory for the reception of anotherrug. The presentinvention thus provides an effectiveapparatus for-.cleaning rugs :and like fabri'cs to '.producef kuni-form"cleaning effects: theree on in a rapidpthorough and` uniform manner without injurious effect on the fibers of the fabf ricl" The invention likewise provides a comparatively' simple, practical and reliable apparatus by means of which the cleaning may be 'conveniently carried-lout. f Y y l fIclaim 1as myinvention: I l.^'n:a rug cleaning machine, in combination, means :for `:feeding a rug through said'machine comprising upperrand lowerv feed-rollers, an up- 4 Wardly movable supporting element on said ma-A chine in which. said upper feed roller is journalled, a vertically :reciprocating beating tool mounted on said V.vertically movable element, a rotatable brushy mounted on said vertically movable ele' ment apositirmed` .adjacent said :beating tool, a
