callyl and to shift the cushion in order to pre-I sent the severalsurfaces to the brushing device. It has been suggested in the prior art that these cushions be mounted on a lbelt or similar travelling platform and passed beneath or `between brushes mounted to ro- 30 tate about fixed or` substantially` finedV axes of rotation.. From a practical standpoint howeverthis method of feedingthe cushions to such brushes has not proven satisfactory M due among other reasons to'the fact that w as the cushions arenot uniform 1n size, and certain parts'of the surface under treatment require a more vigorous application of the brushing treatment than the other parts, the necessary variation in treatment cannot be o attained where all parts of the surfaces are subjected to the same'brushing treatment.

Accordingly, one of the objects of the in# ventionvis to provide a simple form of machine by means of which the intensity of vbrushing engagement between thebrush and the surface under treatment may be at all times under the sensitivemanual controloff an operator who can adjust the pressure of the brush on the surface as the circumstances require andV repeat the operation over the same surface as long as necessary.

Car cushions Vof the type now in general use are quite heavy, weighing from forty to fifty pounds when wet; theyk are somewhat bulky and do not provide any means for gripping them conveniently and they are otherwise not easily handled.

Accordingly, another object of the inventionis to provide asimplied form of mech- 59 anism for handling the heavy cushions and for turning theV same quickly andv accurately into positionrto" permitan economic sequence of brushing operations and at thesametime to provide such a machine designed so-thfatI boththebr'ushing operation and the manipulation of the cushions` can be attained bythe employmentofone man for each machine:

Still another object ofl the invention'- is to provide a simpliiied'form3 of' machine of the' type outlined-which can. be Inadesutliciently' rugged in itsseveral parts to withstand the rough usage towhich such'a machine' islsub# jected and at the sameit-im'e to lprovide'a ma'- chine. which Y canzbeV constructed of .relatively few parts 1 without extensivermachining fop-- eration so that. itcan Ybe manufacturedvand marketed at relativelyf low acost.

Still another object :ofjvthe invention isto provide a machinefoftheftype foutiinedin which the' necessary power to operate it, eX- cept the `power necessary tn drive the revolving and travelling brush,'will1be manualpow# er ofthe operator:attendingithe machine.

InV the following description and in the claims, parts will be identified by specific names for convenience of expression but they are intended to be as generic in their application to similar parts as the art will permit.

The foundation of the machine comprises a rectangular box-like structure including four corner uprights 15 connected adjacent their upper lends by means of front and rear end sills 16 and relatively deep side sills 17 in the form of channel members. Extending across thev top of the skeleton frame thus formed is a top plate 18, and it is understood that this frame is otherwise reinforced and braced to form a rugged structure by structural parts some of which will be specifically mentioned in connection with other mechanism. Gn top of the frame and adjacent its central forward edge is a turn table 19 for supporting the cushion C flatwise as shown in Fig. 2. Positioned in advance of the front edge of the supporting frame is a vertically movable cushion elevating carriage 20 for supporting the cushion edgewise and in vertically disposed position as shown in Fig. 3. In advance of the cushion in all positions thereof is a brush 21 mounted for rotary movement about its own vertically extending axis and driven through a flexible cable 22 leading from a motor or other suitable source of power.v The brush is moved bodily back and forth across thel front of the machine by a gear driven brush rotating and shifting mechanism contained in the reciprocating gear box 28 acting on rack 24 and which brush actuating mechanism is partially shown in this application andis more fully disclosed in my copending application entitled Brush mechanism lfor cushion brushing machine, Serial No. 133,309 filed under even date.

The brush 21 is mounted in a horizontally movable brush carriage 25 slidably mounted so as to bring the brush in variable brushing engagement with the 'cushion in its several adjusted positions. The brush carriage includes a front frame 26 extending across the front of the machine and formed largely of the brush actuating mechanismk and frame for lcarrying the same. From opposite ends ofthe front frame extend side frames 27 which project therefrom each along the adjacent side ofthe side sills 17. The side frames each include a right triangular shaped forward part 28 as shown in Fig. 2 and a rearwardly extending horizontal arm 29 of inverted T shape in horizontal cross section as shown in Fig. 5. Y

It is the intent of the designer of this structure that, insofar as is possible, the weight of the brush carriage 25 be carried ou the forward uprights 15 and inv this way minimize the strain which otherwise would have to be transmitted through the side sills and other parts of the supporting frame. For this purpose the carriage is supported largely by disposing the two side frames 27 thcz'cof on flanged rollers 30 which in turn are carried by the uprights 15 as particularly shown in plan in Fig. 1 and in side elevation in Figs. 2 and Ll. Spaced inwardly therefrom in each case are a pair of

roller guides

31 and 32 rotatably mounted on the side sills 17 and which rollers engage respectively the upper and lower side of the bottom flange 33 forming the head of the T arm 29 as shown in Fig. 5. lt is obvious of course that these rollers assume some of the weight of the carriage 25 as this weight becomes unbalanced on opposite llO sides of the rollers 30. The carriage is moved from front to rear and into engagement Awith the cushion b y means ofV a ttor fardly inclined` as a control for the turntable and a control for a gripping device 35, depending upon the po y sition of the carriageall as will be more fully disclosed hereinafter.

`The turn table 19 is an oblong plate provided on the upper sine thereof with a` pair ofupwaruly facing channel bars 36 disposed` in parallel relationand spaced equidistant on opposite sides of the airis of rotation of the turn table. The cushions @usually have a central bulge or dept-h adjacent the center greater than at the edge as'clearly seen in Fig. 2 and these channel bars assist in insuring the retention of the cushion on the turn table as is rotated.` The turn table is designed to turny With a step by step motion so as to presen'tthe four side Vedges of thecushion to the plane of movementof the brush as it is reciprocated back and forth across the front frame 26. It

ieobviously essential not only to rotate theV turn table ninety degrees at eachstep but it is alsonecessary` to holdV the turn table from rotating thereby to hold the cushion rigidly in place as the brush travels back and forth across the surface of the cushion exposed to the same. For this purpose the turn table is controlled by zin-intermittent feed `movement arranged to rotate the turn table a step at a time until all four sides of the cushion have been `presen-ted to thebrushing opera# tion hereinafter 'described his `noted par?Y ticula 'ly in Figs. 6 and 7 the turn table andr the driving parts turning therewith are as'- sembled as a complete unit, and mounted on abase plate 37 and which in turn is supported on the lower flanges 38 of a pairrof

channel shape sills

39 and 40 extending from table is demountablyf secured by screvvslt.V`

Depending from the lower flange '-of the locking Wheel and positioned exteriorally of the hub l2 are four equally andvcircumferentially spaced apart rollers 48 constituting locking pins and between these locking Sf pins Vand adjacent the outer edge of the flange @i7 are four advancing pins 49. rIhese pins are disposed so as to beV engaged by a pawl 50 to advancethe locking Wheel, and with it the turn table and cushion C into its succeeding positions to present all four side edgesofythe` cushion to the lorush` 21.A AThe.

secured to the base` plate 37:1 Theloar 51 is" demountably secured `in said guideways by Vplates 54C secured to. the top of the blocks by screws 55.- The'bar 51 is reciprocated from fronttoi rear of themachine by mechanism actuated from the lever 34 as hereinafter described. The paWl 50 is maintained normally'in thevpath of rotary'movement of the advancingpinsll) by means of a pawl spring 56 Which tends normally to move` the paWl into engagement ywith a paWl stop 57. The

patvl is of the Oneway/acting type arranged to advance or rather to-start the rotary action of the turn table locking Wheel clockwise as indicated by the arrow 1in Fig. l and the pawlr is arranged so thaton the retreatof the slotted bar 5l itis free tovpass the next advancing pin49 Which has been rotated into position in ladvance of the pavvl during the final period of the previous advance ofthe slotted 4bar. edge facing the locking pins or rollers i8 with a slot or recess 58 disposed to receive and ad-l vance the lockingpin advanced into the'same by the pawl and then to act on the loclringpin to rotate the turntable vunderthe action of the intermittent feed movement illustrated. The slotted bar is provided With a straight edge 59 constituting a locking edgeand fromthe showing in Figs. 1 and 6 it Will be noted that the partsare so designed that When'the4 locln The bar 5l is lprovided on the'V ing Wheel has been fully advanced tWo of the y locking. pins i8 will be in line with and one ofthem Will be held from rotation by the locking edge and Will be so held until the next advance of the slotted barvpermitsand causes the foremost of these tivo lool-:ing pins 48'to move intoV and` out of the slots 58.

The slotted bar'l is reciprocated baclrand forth to rotate the turn tablethus dese V1ibed and -to release the gripping device 35 through the roclring of the main shaft 605'actuated by control lever 3e and controlled by the position of the carriage side frames 27.

rllhe main shaft 'extends longitudinally of the machine beyond the side sills defining right vof the machine will equally apply to the corresponding structure at the left of the machine. The lever 61 includes a foiurvardlyv extending'and depending arm 62 which is connected by a reach rod 33 tothe lower end of an arm 64 the upper end of which arm is lill) secured rigidly to a shaft rotatably mounted in the front frame 26. To the arm 64 at the right hand side of the machine is secured the control lever 84. lt is obvious from this construction that th-e swinging of the control lever can actuate the locking levers at opposite sides of the machine when a movement thereof is permitted by the position of the brush carriage 25 and that both ends of the main shaft are rocked simultaneously. rl"he upper rearwardly extending arm 66 of the lever 61 is so disposed to be engaged by the underside of the flange 33 forming part of the arm 29 which engages the same when the brush is close to the cushion and holds the lever 61 from counterclockwise rotation as shown in Fig. 2. With the carriage moved forwardly, away from the cushion and with the arm 29 clear of the locking' lever 61 it is possible for the lever 34 to rotate and thus rock the shaft as indicated in the full and dotted line showings in Fig. 4.

When in the locked position shown in Fig. 2, the reach rod 63 is held rigidly from movement in either direction. The lever 61 cannot rotate anti-clockwise due to its engagement with the arm. 29 and the rod 63 cannot move from left to right of the showing in Fig. 2 due to it being held by a pair of toggle links 67 which at this time is in elongation with and in effect constitutes a continuation of the. reach rod 68 securing the same pivotally connected by means of pin 68 to the adjacent rear upright 15. For the purpose of breaking the toggle connection and thus permit a rocking of the main sha-ft 60, a horizontally extending unlocking link 69 is pivoted to the pin 68 and underlaps a pin 70 which projects laterally from one of the toggle links 67. To the outer end of this horiontal link 69 is pivoted an npstanding lifting link 71 provided with a slot 72 containing the main shaft so as to guide the lifting link in its vertical movement. To the upper end of the lifting link is positioned a roller 7 3 disposed in the path of movement of a wedge 74 secured to the outer end of the arm 29. From this construction it will be noted by comparing Figs. 2 and 4 that the forward or right-to-left movement of the carriage will cause the wedge to engage the roller, lift the toggle links 67 from their aligned position shown in Fig. 2 past the full line and into the dotted line position shown in Fig. 4, so that a continuous depression of the control lever 84 after it has advanced the carriage to its forward position as shown in Fig. 3 will cause the releasing of the locking toggle links and a subsequent rotation anti-clockwise of the main shaft over an angle of about forty-five degrees.

Tracing the link connection between the main shaft and the reciprocating rod 51 which rotates the turn table, there is shown particularly in Figs. 3 and 9, a depending arm 75 rigidly secured to the main shaft just outside the sill 40. The lower end of the arm is connected by a link 76 to the lower end of a lever 77 rigidly secured intermediate its length to a secondary shaft 78 paralleling the main shaft and mounted at opposite ends in brackets 79 secured to the supporting frame as shown in Figs. 3 and 9. The upper end of the lever 77 is pivotally connected by means of a link 80 to the rear end of the slotted bar 51 forming part of the Geneva movement. From this construction it is obvious that the movement of the control lever from the full line into the dotted line position shown in Fig. 4 will rotate the main shaft anti-clockwise and this motion in turn It is required however that the clamping jaws be released from their engagement with the cushion prior to the rotation of the turn table and accordingly the present disclosure features an arrangement whereby the jaws of the gripping device are moved into an inoperative position by the same mechanism which controls the turn table and in proper timed sequence to permit the complete release of the cushion before the turn table is moved. For this purpose there is loosely mounted on the supplemental shaft 78 an upstanding arm 81 which is normally held in inoperative position retracted towards the back of the machine by a spring 82. The arm is moved in the other direction and against the tension of the spring by means of pin 83 which projects from the upper arm of lever 83 fixed on shaft 78. As the lever 88 swings under the action of the rocking main shaft 60 it causes the arm 81 to swing with an anti-clock- 1 wise movement from right to left as shown in Figs. 3 and 9. Positioned in the path of the upper end of the arm 81 is one arm of a bell crank lever 84 (see Fig. 1) pivoted on a bracket 85 extending laterally from the center sill 40 and the other arm of which lever is designed to engage a long arm 86 the rear end of which is pivotally connected by pin 87 to the rear sill. The forward end 0f this long arm is overlapped by and is designed to engage a stop 88 at one end of one of the movable jaws of the gripping device. A long spring 89 tends to move this long arm into an inoperative position engaging a stop 90 and this permits the spring 181 llO which controls thejavvs to move thesame-into clutching positionwith the cushion when released by the longlarmduring its return into its inoperative position as shown in dot and dash lines in Fig. 1.

y It is required that the clampingjaws be positively heid- -in inoperative position as lshown invfull-flines Ein Fig.- 1` until-thelturn table has completedits quarter movement. For this purpose the arm-81 (Fig. 9) has -pivoted thereto a--loclring bar 91 provided on its underside With a flocking notch 92 and which baris designe-d to slide over a square block 93 `secured to the main shaft. The locking bar is normally held `in=engageinent with a.

flatu face `ofthe block bymeans of al` spring 94 connecting the bar 91 vvithfthe `arm 81. lThe main shaft is provided with a lug which? is designed as the main shaftl isrerotated to lift the locking bar sothat the notch thereinW-ill Vclear the square-locking blocl and thus permit the spring l82jto draw the-arm 81 out of position engaging the lever 84 and thus permit the long arm 86 to swing bacl-z into itsv inoperative position undertension of its spring 89.1 Fromthis construction it is seen that-the ygripping device-.is held by the loclringbar 91 ininoperative-positi'cn even after the lever V77'has begun to sWing'back and during the initial return to normallof the main shaft. The grippingde` viceV is held open While the lug 95 on thev main shaft is turning upwardly from the pesiti-on shown Vin Fig. 9 and until it engages the underside of and has lifted the locking ture ithere is shown a long block 96 secured to the forward upper .face of which is a bracket extension'y 9T -triangular in side elevation.4 Eachof these'blocksis mounted on an up right 98 and Which two uprights'are positir-med at the Vfron-tof the machine spaced inwardly from the cerner uprights l and poA siticned on opposite sides of the turn table; as shown' in Fig. 1e these uprights 98 each comprises-two

channels

99 and 100 withA their backs spaced apart. The loWerend of' the bloclr`f`90 is provided With a pair of angle pieces l101 positioned on opposite sides and engaging in the channel of its adjacent upright asshovvn inFig. 3.y Positioned above theseangles is Vpair of plates 1027 103-` (see Fig. 14.) eachofvvhich carry a pair of rollers 10a-10.5 `positioned onopposite sides of the flanges ofthe associated-channel bar. Frein this construction it is seenthat both of the blocks which ccact to form the carriage are mounted to slide freely and thisfi's particularly-necessary Wher'eheavy cushions are tol be raised and lowered manually or by foot is slotted-asl'shown-at 110, Fig. 11, to receive a-norma'lly horizontal 'extending ycushion edge suppert 111v with `its forward end upturned asshownatf112 and'its rear end pivoted on pivotpin 113carrie'd by the upper end of the block. This supportlll-is adapted to be engaged -by a tilting lever'115 pivotally mounted intermediateits length on the block ert'ension andvdesigned When the carriage is elevatedlto the limit-:of its upwardmovement tolengage the lower edge-116 of the front sill so 'as to lift the outerfendofthe support-as indicatedin Fig. -11 andth-us 'act to tilt* the cushion from thefvertical position shown in Fig; tovfar-dsy the-turntable-or towards the cushion tilting mechanism 117 l hereinafter described-When it is-des-ired tov-move Vthe cushion from thelvertical backinto the hori- -zcntal positionne shown in Fig. 2.

The gripping device 35' for clamping the cushion is carried by the cushion elevating carriageso-as to clamp thecushion When on thefear'riagelas shownt in Fig. 3, and is also pivotally mounted so that itfcan be lswung intovhorizontal posi-tion"when on'the turn table as shown in Fig'. 2, and-alsowhen moving from=one of theseposi-tions into the other Vendl-ir contrclof the tilting mechanism 117.

The gripping device 35. comprises in eliect three-parallel bars (see V10) ;-tWo outer jaws carryingbars 118 and1119-and an intermediaten-relativelyiixedbar 120. 'f rThe fixed bar Vis `:pimifct'ally-mcuntedby means vcfa pair of hingev connections 121 and invv'ardly'projecting brackets 122 secured to theupper' inner `face of the blocks '96 as particularlyshovvn in Figi-13. Each of the bars 118 and )1194s provided 'adjacent its outer endfwith y.'lsli'a'ped elevatingmember 123. Thefouter endofthe-bar 119 is `provided With the Iupturned stopjl vpreviously referred to. These elevating members 123 each include a laterally-1 extending-'i' member '124 `provided with two upstandingfcushion engaging pins 125 constituting 'the vclamping jaws. These elevating members also include a laterally extending member 125 having a length sufficient to extend under the cushion, and of a length sufcient to overlap the tilting mechanism 117. The forward ends of each of the members 124 are formed into a rectangular block 127 which encircles the ba'rs`118, 119 and 120. The left block is secured to the bar 118 and the right block is secured to the bar 119 by means of screws 128. Adjacent faces of the bars 118 and 119 are provided with racks 129 in mesh with a pinion 130 carried by the fixed bar 120 and so arranged that movement of one ofV the bars is transmitted therethrough to the other. A spring 131 between the blocks 127 tends to cause these cross members to be moved normally into cushion clamping position when released by the long arm 86.

Mounted in the front of the machine adj acent the ground is a shaft 132 journalled in brackets 133 carried by forwardly projecting extensions 134 from the base of the machine. Secured to the shaft adjacent the right side of the machine is a lifting arm 135 connected by a link 136 to the lifting lever 107 which controls the raising and lowering of the vertical carriage 20. As it is intended that the carriage be moved with a step by step movement to permit the brush to traverse across the face of the cushion along succeeding bands as the cushion is elevated or depressed step by step, a disk 137 provided with a series of one-way notches 138 is secured to the body of the machine by a bracket 139. Loosely mounted on the shaft adjacent the disk 137 is a foot pedal 140 provided with a pawl 141 adapted to engage in the notches on the disk. rlhe pedal 140 is provided with a pin 142 which engages a shoulder 143 on the arm 135 to elevate the same. The pawl is controlled by a toe plate 144 pivoted to the outer end ofthe pedal and designed to be rocked to remove the pawl from the notches when it is desired to permit the carriage to drop which it will do of its own weight.`

The tilting device 117 includes a pair of tilting arms 145 hingedly mounted on the front sills on a bracket 146.V The arms 145 are positioned to the outside ofthe cushion in all positions of the same and in each case underlap the transversely extending members 124 of the clamping device so that when the tilting member is elevated it will carry with it the means for holding the cushion from lateral movement parallel to the width of the machine. Each tilting arm is controlled by a pair of pivotally connected lifting links 147 148 the latter of which is connected'by means of a reach rod 149 to a tilting arm 150 loosely mounted upon the shaft 132. s

This lever is controlled by a foot pedal 151 fixed to the shaft 132 and provided with a pawl 152 designed to engage the single notch 153 in a notch plate 154 secured to the extension 134. A lug 155 on the pedal 151 acts on a projection 156 on the arm 150 tol raise the same and with it the arm 148 of the tilting device. The shaft 132 provides the connecting means between the two arms 150 as particularly shown in Fig. 1.

From this construction kit is understood that depressing the foot pedal 151 acts throughv the two linkages to lift the tilting device asa unit from the horizontally disposed position shown in Fig. 2 into the vertically disposed position shown in Fig. 3 at the end of which movement the pawl 152 engages in the notch 153 to hold the tilting device in the upright position shown in Fig. 3. Releasing the pawl 157 by the depression of the toe releases the locking effect and permits the tilting device to fall back by virtue of its own weight into its normal horizontally disposed position on opposite sides of the turn table as shown in Figs. 1 and 2.

rlhe lug and projection form of connection shown at 142, 143 permits the pedals to be lifted up out of the way when not in use and disposed vbeneath the horizontal carriage 25 as shown in dotted lines in Fig. v2.

In operation the cushions, after they have been dipped into or sprayed with some suitable cleansing material usually employed in this art, are positioned on the turn table as shown in Fig. 2 and while the brush is in spaced relation to the adjacent edge of the cushion as indicated in the position of the brush shown in Fig. 3. Vhile positioning the cushion on the turn table the gripping device is moved into its inoperative position, spaced from the cushion as indicated in Fig. 1. No particular care need be exercised in positioning the cushion on the turn table except to make sure that the bulged center of the cushion is positioned between the parallel channel members on the top of the turn table. Releasing the gripping device permitsv it to engage opposite side edges of the cushion and tends to center and to hold the same against the shift-ing effect of the brush. The brush is caused to rotate; the spraying device 159 is set in operation and the brush is caused while rotating to reciprocate back and forth across the front of the machine as is more particularly defined in the above identified co-pending application. Y

Bylifting the hand lever at the right of the machine the operator causes the brush as a whole to be moved from front to rear and into operative brushing engagement with the side edge of the cushion which is facing the same as indicated in Fig. 2. By means of this lever the operator may maintain any desired intensity of brush engagement with the cushion.

TWhen one side edge is brushed the operator depresses the control lever to withdraw the brush from the cushion and at the end of the outward movement of the brush carriage the gripping device is released as hereinbem notches 138 one at a time.

mer/cried fore described. On the upstroke the turn table is rotated by the action of thefGreneva movement so as to bring the neXt adjacent side edge into the planeiof movement ofthe reciprocating brush and the clamps arereleased as the turn table completes 90 revolutions and about the time the control lever 341-. is horizontal. The operator then continues lo lift the control handle from the horizontal position towards the elevated position shown in Fig. 2 to bring the brush into engagement vrith this brush surface.` This Loperation is repeated until all four side edges of the cushion have been brushed.

.By pressing the proper lever for controlling the tilting mechanism the cushion and with. it the gripping device is elevated from the horizontal position shown in Figs. 1 and 2 into an elevated position somewhat raised from the `position shown in Fig. 3 at which time the lifting carriage is in its uppermost position and disposed to receive thecushion as. it is dropped on to the same. When elevated asshown in Fig; 3 the clamping device is resting on top of the bracket 97 and the members 145 are held elevated to prevent the pressure of the brush from tilting the cushion back on tothe turntable. A hook 158 projecting from the free end of each of the members 1115 is disposed When elevated to receive the arm 126 .and act thereon to return the clamping device to the horizontal position shown in Fig. 1 and Fig. 11. YVith the cushion thus held in its .vertically disposed position'the brush is. advanced into engagement With the wide surface ofthe cushion and the operation is repeated as has been described for the brushing ofthe side edges.

Preferably the brush is of less heighth than the corresponding dimension of the flat side of the cushion and in this case the brush caused to traverse horizontal bands of brushedspacesV across the face of the cushion. Preferably the brushing operation is started at the bottom of the cushion With the carriage 20 in its highest position somewhat above the position shown in full lines in Fig. 3 and in Which position it is held by the pedal 14() engaging one of the end notches in the notch plate at thebase of the machine. As each band is successively brushed the carriage is lowered a distance to bring apartiallybrushed or unbrushed portion of the cushion into position facing the brush until finally the elevating carriage is in its lowermost position shown in dash lines in Fig. 3.

This gradual. lowering of the carriage is attainedsiniply by depressing the lever l140l so that its pawl 141 Will engage succeeding This successive `brushing of succeedingly spaced bands is continued until the entire flat `surface; or vtopof thecushion hasA been treated.

After being brushed, theV rinsing spray 159 is turned on. andthecushion is then brushed the-combination; ofwmeans including a band after band previously described eX- cept that `the cushion iselevatedfstepfby. step `untill the 'lifting carriage is-moved to the limit of its upwardfmovement. In this position the supports 111fengaging the narrovvrside edge of the cushion is dipped towards the ma-v chine as; `previously `described and the' cushion Y being thus 'unbalanced' is pushed 'to drop .baclrionto the f lifting' device which by f this ime` istilted. intoA position ,.to' receive' the tipped cushion. By the actuation ofthe pedal controlling the: tilting device the cushion is easedback on tothe turn table. If it is desired to brush' the otherfflat side,tl1e

cushion is reversed on the turn table from which it; is Yeventually Withdrawn either manuallyv or by inechanisnfrforming no part of the present disclosure. f

By means of a device of the character outlined ithas been found possible to handlethe heavy cushion seats conveniently and economically and cushion after cushion may be Vfed through thev machine at about thesame .ed positions and itis readily and easily shift- -3 ed from one to another of the positions facing thebrush.`
