In Great 17 Claims.

This invention relates to garment-renewing machines of the type in which the fabric to be treated is placed .upon a support and is pressed upon by a rotary rubbing face to which may be supplied a fluid which .comes between said face and the fabric.

In machines of the type stated as hitherto used, the rubbing face is presented by a single rotary device. The rotary device consists of a holder .in which is inserted an abrasive disc suitable for giving appropriate pile-raising or other renewal treatment to a garment. This device must be worked over the surface ofl the vfabric, including seams, with the result that the rate of progress is slow. l

The rotary device, which presents a rubbing face, is .embodied in a so-called pressure head. .In use of the machine a worker holds the pressure head by a control .handle and presses the rotary device upon the work. The magnitude .of the pressure applied by the rotary device to the .fabric is a vitally .important factor in the per.- iormance of the work, .so much so that the sense of feel in a worker must be developed by thor ough training before she can use one oi these machines successfully.

An object of the present invention is to make provision in a-machine/of the type .stated whereby Ia reliable indication of the pressure being exerted on the work is continuously presented to the worker so that she `is enabled to maintain the pressure at some predetermined `magnitude without relying l,upon her own sense of feel.

.Another object .of Vthe invention is to provide in a machine cf the type stated a plurality ci rotary Afabric-renewing .devices which .are appli-` cable under pressure to vthe .fabric and which are spaced around the axis oi apressure head'wherein they are incorporated, the `rotary devices being respectively geared with a central drive.

, Another object is to provide in such a machine a pluralityy of normally co-planar rotary fabricrenewing devices applicable simultaneouslyunder pressure to the fabric and in which the rotary devices are 'individually movable against spring resistance in relation to one another to allow for formations such *for 'instance as seams Yon, or varying textures in, the fabric. The movements o which the devices Vare individually capa ble may comprise vertical and tilting movements.

The pressure head may have a handle lsc supported that by `manipulation of the handle the head and the assembly oi rotary devices therein incorporated can be turned about the axis ci the Britain September 16, 1.944

2 pressure head to suit the lie of the work on the garment support,

Another object of the invention is to provide r'in `such a machine an assembly of rotary devices mounted in the pressure head so as to be displaceable as an assembly in the headagainst a yielding spring resistance when working pressure is applied to the pressure head.

Yet another object is to provide in such a machine locking means, preferably automatic, to holo; the one or'more rotary devices down to their wor In a preferred form, the machine has one or more rotary fabric-renewing devices arranged on a holder and adapted to be applied to the work against spring pressure, such application involving relative movement y,between said holder and devices anda pressure gauge on said holder operatively connected lto the one or more devices and adapted bythe relative movement to give an indication ofthe applied pressure. The machine also includes an overhead support, an extensible connection between said overhead support and the holder on which the one or more rotary devices are arranged and a locking device serving to lock said holder against return movement relatively to said support when said connection is extended by the application of working pressure to a magnitude indicated by the gauge.

A garment-renewing machine embodying the invention will now be described by way of example with reference to the accompanying drawings in which:

Fig. 1 is an elevation ci the machine in out-ofuse position, portion-s of parts being broken away and shown in Vsection for clearness. Fig. 2 is a section -on Ithe line V2"2 oi Fig. 1, being drawn to a larger scale. Fig. 3 is a plan of parts constituting the `top oi the machine. Fig. 4 is an elevation partly in section, of parts shown in Fig. 1, but lowered into their working position, thisy View lalso being drawn to a larger scale than Fig. 1. Fig. 5 4is a mid-section of parts of the machine as shown in Figs'l and 4, being drawn to a still larger scale, and Fig. 6 is a similar view of other parts. Fig. 7 isA a fragmentary sectional elevation of the component herein referred to as the pressure head, the section being approximately on the line 1--1 of Fig. 9. Fig. 8 is a sectional plan of the pressure head, the section being on 'the line 8--8 of Fig. 1 and the view being drawn to a larger scale. Fig. 9 is a fragmentary section approximately on the line 9-9 of Fig. *7, certain of the parts being broken away te show parts below them. Fig. 10 is an inverted plan of one of the rotary fabric-renewing devices fitted with an annular brush.

The means whereby the working components ofthe machine are supported comprise a base I, a vertical post 2 at one side of the base and a horizontal jib 3, extending overhead acrossfthe 4base from the top of the post, a motor-carrying structure 4 from which a pressure head 5 depends being carried by and immediately below the jib and a buckboard 6 constituting the garment support being mounted on the post. The jib and the buckboard are connected respectively at 'I and 8 to the post, and either one of the connections may be a swivel whilst the other is rigid with the post. Thus, provision is made for relative lateral movement between the pressure head and the work, which is denoted by 9, Fig. 4.

To ensure steadiness in use of the machine the' base has a three-point support, namely threey runners or casters I9, one of which is located near the post at the rear of the base and the other two of which are near the front corners thereof. The base has a cabinet II which can be .equipped as a garment-drying receptacle by fitting it with appropriate air heating means.

The pressure head includes an assembly of three rotary fabric-renewing devices I2, although any desired plurality may be used. The devices (see Fig. 7) are connected to rigid vertical shafts I3 journalled in a locating plate I4 which consists chiefly of three radial arms. The holder of the devices I2 and plate |4 is a casing I5. The plate I4 is vertically displaceable in the casing I5, being guided by arcuate flanges I6 at the ends of its arms sliding against faces I1 in the casing. The flanges I6 have feathers I8 that are slidablegin slots ISA formed in the faced portions of the casing I5 to hold the plate I4 and the rotary devices I2 against turning movement relatively to the casing I5 around the vertical axis of thecasing. That is to say, the devices I2 are confined to rotation about their own axes. device-carrying shaft I3 is polygonal in crosssection and has a gearwheel I9 connected to it,

, andthe three gearwheels I9 are arranged around a central gearwheel 29 with which they mesh in the manner of planet-wheels with a sun-wheel. The central gearwheel is keyed to a rigid vertical -rotary shaft 2| forming a part of a telescopic driving shaft dependent from overhead. The device-carrying shafts I3 are capable 0f limited vertical movement relatively to the plate |4 through the gearwheels I9, which are journalled in ball-bearings 22, 23 on the plate I4 and are held against vertical movement relative thereto by an abutment nut 24 on the elongated boss 25 of each of these gearwheels. Small strong springs Each,

and the associated abutment nuts 24 to oppose upward movement of the rotary devices and their shafts I3 relatively to the plate |4. A set screw 21 on each shaft I3 limits its downward movement, the arrangement being such that each groove connections 30 with one another (see Fig. -'1). 'The arrangement is such that each rotary device |2 is not only capable of being forced up- "rotary device I2, when pressed upon the work 9,

4 wards independently of the others but can adopt a position askew to the axis of its shaft I3, for

example if necessitated by the contour of the raised portion of the work 9, say a seam, that device will be forced to rise relatively to the others and will tilt itself, by virtue of its universal joint 2li-30, in so far as may be necessitated by the lie of the work.

The previously mentioned telescopic driving shaft also includes a length 3| the lower end of which is formed as a socket 32 which is slidably connected with the other shaft part 2|. The part 2| and socket 32 are polygonal in cross section. The foot of the shaft part 2| is supported by a foot-step ball-bearing 33 in the boss 34 of the plate I4 and the other shaft part 3| is journalled in a ball-bearing 35 in the casing I5.

A compression spring 36 is interposed between a collar 3IA on the shaft 3| and the central gearwheel 2U, said spring functioning to urge the entire assembly of movable parts constituting the active components of the pressure head towards their lowermost position, in which they are shown in Figs. 1 and 7. This lowermost position is determined by the feathers I8 engaging detachable stops IBB which close the otherwise open bottom of the slots |8A provided for the feathers in the casing I5. Thus, when the rotary devices I2 are brought into engagement with the work 9, sufhcient downward pressure on the casing I5 forces them, together with the gearwheels I9 and 29 driving them and the plate I4 supporting them, as an assembly upward in relation to the casing I5, the extent of movement being proportional to the magnitude of the downward pressure. In this relative movement, the shaft part 2| telescopes in the socket 32, the spring 36 being compressed.

The casing I5 is suspended from the motorcarrying structure 4 by a telescopic tubular shaft assembly, comprising an outer tube 31 secured by a xture 38 to the base of the structure 4, an inner tube 39 secured to the handle 4B of the casing I5, an intermediate guide sleeve 4| interposed between upper and lower portions of the outer tube 31 and a locking case 42 secured to the vfoot of the outer tube and serving inter alia as a guide for the inner tube. Relative turning between the tubes 31 and 39 is prevented by a feather 43 and groove 44 in the tubes 39 and 31 respectively, said feather and groove forming a connection which permits the tubes to telescope.

The pressure head 5 is supported by tension springs 45, which if desired may be enclosed in telescopic cases (not shown). The springs 45 are attached to lugs on the fixture 38 and to lugs on a collar 46 secured to the inner tube 39. In Figs. V1 and 4, the spring 45 therein shown is broken away to show parts behind it.

TheA telescopic tubular shaft assembly 31-4I vand the central driving shaft 2|, 3|, 32 cons. freely .turna-ble angularly about its vertical axis, is freely movable lengthwise. of the buckboard 6 and is. freely movable relatively to the buckboard crosswise thereof. The free angular movement is got by virtue of a swivel mounting at 4.1 between. .the top of the structure 4 and a trolley boss 48 -on the jib .3. (see Figs- 2 and 3). The free lengthwise movement is got by virtue of the trolley boss 43 having two upper pairs of wheels 49 and twol under pairs of wheels 5l] all journalled on armsv 5| and riding upon rails 52 shown as ledges formedin two side-by-side members constituting the jib 3. The free relative crosswise movement is got by virtue of the previously mentioned pivotal mounting of the jib vor the vbuckboard on `the post 2. All of the movements'of the pressure head are got by application of the Arequisite forces to the handle ,40 on 'the part of the operator. In regard to the .anguiar movement, such is got by appropriate manipulation of lthe handle 43, for instance in order to align .the rotary devices I2 with formations such as seams or ridges on the surface of the fabric constituting the w-ork 9, That is to say, it might be desirable to work one device (or two devices) along a raised surface of the fabric beyond a longitudinal, transverse or inclined seam whilst working the other two devices (or other one device) over the main surface alongside the seam, the differences in level being automaticall'y allowed for by appropriate yielding of the springs 26 individual to the devices.

'Ihearrangement is such that the pressure head with or without the garment-,supporting buckboard can be moved about by the operator as the work progresses, in vorder to bring any portion of the work under the action of the pressure head.

The drive to the rotary devices is imparted `to their central driving shaft 3l by an electric motor 53 through intermeshing gearwheels 54, 55. -The Ymotor is supported by a bracket 56 on the carrying structure 4, being arranged with its axis vertical. Ihe gearwheel 55 is journalled in v`ball-bearings- 51 (see Figs. 2, 4 and 5) in a bracket 53 secured to the structure 4. The shaft 3l has a sliding connection with the gearwheel 55, the uppermost portion of the shaft and the bore of the gearwheel being polygonal in cross-section. Thus, in Ythe falling and rising of` the shaft 3| with the pressure head 5 to and from the buckboard E, the gearwheel 55 remains located in its bea-rings.

Each rotary device I2 comprises mainly a disc 59 made of rubber or other abrasive material (see Fig. 1), the disc being clamped in place by a ring holder 6.0. A brush 6l may be used in combination with each disc with Athe objects of cleaning and otherwise preparing the texture of the fabric 9 for treatment by the the fabric liquid supplied thereto through the disc, and raising and improving the nap of the fabric after such treatment. In the example, the holderf of each disc 59 annular collar 62 (see also Fig. 10) which is faced with the brush material 6l, for instance bristles or hair, and which is secured to the holder by means of say a bayonet joint 63, or otherwise as may be convenient. Instead, the arrangement might be such that each disc is removable from its holder and is replaceable by a circular brush of substantially the same size as the disc. A machine having such brushes for use in place of the abrasive discs can be used for dry surface cleaning of garments.

dsc, removing from is adapted to receive an` 'The machine shown is equipped with an over head` reservoir 6.4 for lthe chemical liquid to be supplied to the pressure head for y.appligation through the rotary devices I2 and rubber discs therein tothe .fabric preliminary to the.- usual treatment with the liquid. The reservoir 64 ,is mounted on the motor-carrying structure 4, which is made as a closed. housing for the motor 53. and associated gearing and for the reservoir. The lliquid is led through piping 6.5l to the handle 4B', which is provided in known manner with an internal self-closing valve (not shown) adapted 'to be opened by depression of' a nger lever 66 o n the handle. Piping 61 from the handle leads tobranches 68 (Figs. '1 and 8.) having three small `control/valves 69 from each of which extends a supply spout 1.3 directed upon the inner wall 1..| oi an annular chamber 12 on the associated ro.- tary device l2. The chamber 12 of each device opens through ports 13 to the active face vof the disc 59.

The motor-supporting structure 4 also encloses a switch connected in thev motor circuit and adapted automatically to start and stop the motor 53 when the pressure head 5 is` lowered for and returned from work. In the example, the

automatic switch is of the lfluid type, comprising a tiltable tube '-14 made of a suitable insulating thermo-setting plastic (such as that marketed under the trade-mark Bakelite'). The tube 14 is carried by a leverv 15. -tl'ig 2) fulcrumed on a bracket 15 secured toa wall ofthe structure .4. The lever is acted upon by a spring 11 that holds, or strives to hold, the lever 15 against a stop 18, the tube 14 then being in a position in which the `huid-namely, mercury or an electrically-con.- ducting oil-makes contact between the switch terminals, which are connected in the motor circuit. The tube is arranged to co-operate with a striker 19 on top of the shaft 3|. The arrange.- ment is such thatwhen the pressure head 5 is permitted by the worker to rise to the position according to Figs, 1 and 2, the str'ker 1-9 uptilts the switch 14, 15 and the fluid breaks contact, thus stopping the motor. Conversely, when the pressure head 5 is lowered towards the work, the striker 13 falls from the lever 15, and the spring pulls the switch into the motor-starting position, so that by the time the rotary devices l2' reach the work 9 they are rotating at full speed.

In the mach-ine shown, provision is made for holding the rotary devices down to their work against the upward pull of the springs 45 upon the `inner tube 39, so that the work will continue under the pressure of the spring 36, such pressure being proportional to the extent to which the spring 35 is compressed by the operator in forcing the pressure head 5 upon the work (Fig. 4); The means'provided consist of an automatic one-way clutch (il)` housed in the previously mentioned locking case 42, which is secured to the outer tube 31 and embraces as a guide to the inner tube 39. The clutch B0 (Fig. 6) is of the known ring type sometimes referred to as a friction pawl, the ring being formed so as to encircle losely the inner tube 39 and its inner periphery being edged so that the ring bites the inner tube 39 when the ring adopts the fully inclined position in which it is shown. One side of the clutchvring rests at 8| upon the bottom of the locking case 42; and the ring cooperates with the stop 82 depending from the cover of the oase 42. The clutch ring 8.0 automatically adopts the lockingv position in which it is shown because .of its tendency to. fulcrum about the stop 82 and bite hard upon the inner tube 39 under the urge thereof to rise under the pull of the springs 45, the arrangement being such that the ring effectively prevents upward movement of the inner tube so long as the ring adopts its fully inclined position.

The clutch ring is capable of locking the inner tube 39 only against upward movement; that is to say if downward pressure is applied by the operator to the pressure head 5, when raised, the clutch ring cannot hinder downward movement of the pressure head, the inner tube 39 sliding downwards freely through the ring.

A nger piece 83 is arranged diametrically opposite to the stop 32, projecting freely through the bottom of the case 42 and engaging the ring 89. In the even that the pressure head 5 is lowered and the inner tube 39 is locked by the ring Ell against rising, the operator can pull down the ring B by means of the finger piece 83 into a non-locking position, in consequence of which the springs 45 pull the pressure head upwards into the out-of-use position.

A spring 84 may be provided to expedite and render surer the automatic action of the ring when adopting and maintaining its locking position. It is convenient to arrange the stem of the iinger piece 83 through the spring 84, if a spring is provided.

In the machine shown, a pressure gauge 85 is provided on the casing I of the pressure head in order to indicate to the worker the magnitude of the pressure being applied to the fabric 9 by the rotary fabric-renewing devices I2 collectively. As shown in Fig. '7, the plate I4, which rises and falls as part of the assembly of working parts within the casing I5, is connected at 8B to a rod 8'! the top of which is formed at 88 as a rack, which forms a component of the pressure-gauge mechanism. This mechanism also includes a pointer 89 (Fig. 8) co-operating with a graduated scale 99 marked with any appropriate values or units, such for instance as lbs. per square inch, indicative of the total pressure applied by the rotary devices. The pointer is connected in known manner through appropriate gearing (not shown) within the gauge 85'to the rack 38.

The buckboard 6 consists of a single ironing board or the like. The board may form one of a number of such boards, respectively made for different classes of work. These boards are made so that any selected one of them may be rigidly attached to the connection 8 provided for them on the post 2 of the machine. Any appropriate means of attachment may be provided. For example, as indicated by Fig. 1, the board 6 may have secured to its underside a channel 9| which is adapted to slide firmly uponoa T-section arm 92 extending horizontally from the connection 3. A device 93, such as a set-screw or a spring catch, may be provided on the channel 9| for locking thereof to the arm 92 in the proper po sitional relationship of the board 6 to the connection 8.

The garment renewing machine is operated in the following manner:

When the machine is not in use, the pressure head 5 adopts its raised position, in which it is suitable to the'work is secured to the connection 8. Thereafter, a fabric 9 constituting the work :is appropriately placed upon the buckboard. The operator grasps the handle 4B and presses down the pressure head 5, against the pull of the springs 45, towards the work, depressing the lever 66 in the usual manner as the work is reached in order to start the ow of liquid by way of the valves 69, which are open to a previously regulated extent. As the operator lowers the pressure head, the inner tube 39 slides freely through the clutch ring 8D; moreover the striker 'I9 is retracted from below the lever '15, with the result that the switch 'I4 is tilted to close the motor circuit and thus start the motor 53. Accordingly, by the time that the rotary devices I2 reach the work (Fig. 4), the devices are rotating at full speed and liquid is being supplied to the work through the ports 13. The operator continues the downward pressure in order that the rotary devices will exercise the desired working pressure upon the fabric. Accordingly the spring 36 is forced to yield by the assembly of working components within the casing I5. Meantime, the operator watches the pointer 89 of the gauge 8'5. When the pointer reaches a mark suitable for the working pressure to be exercised upon the work in hand, the operator ceases to press downwards upon the handle 40, with the result that the automatic clutch ring bites into the inner tube 39 and locks the entire suspensory apparatus against withdrawal from the work. l The upper reaction against the suspensory apparatus by the work is taken by the lower trolley wheels against the rails of the jib 3. The operator now moves the pressure head 5 over the work, turning the pressure head if desired about its vertical axis by swivelling at 48, or moving the pressure head laterally by movement of the trolley along the jlb 3, or effecting relative crosswise motion between the pressure head and the buckboard 6 about the axis of the post 2.

In the foregoing description of the operation of the machine, the three rotary devices I2 are considered as an assembly. In the event that one or more of these devices encounter formations on the fabric different from the general plane of the work, such device or devices will automatically adjust itself or themselves by virtue of the springs 26 and universal joints `28, as hereinbefore explained.

In the event that one or more of the rotary devices are being inadequately or excessively supplied Iwith liquid, appropriate adjustment is made to vthe associated valves B9.

When the Work in hand is completed, the operator pulls down the finger piece 83, thus unlocking the clutch ring 89 with the result that the springs 45 lift the pressure head 5 into the outof-use position. As usual the operator releases the finger lever 66, so that the supply of liquid is shut off. As the out-of-use position is approached, the striker 'I9 returns the switch 14 to its raised position, in which the motor circuit is opened Iand the motor stopped.

The machine hereinbefore described with reference to the drawings is an example embodying the invention and is subject to modifications. For example, in a machine not having a locking device, such as the automatic one-way clutch 80, and not having la pressure gauge to indicate the working pressure, the drive from the overhead motor to the pressure head need not consist of rigid members such as the driving shaft 2I, 3|

and the tubular supporting means 3l, 3e but may consist of aV flexible cable drive such as is already known in machines of the. type tol which this invention relates.
