CARPET CLEANING AND DISINFECTING MACHINE.

Patented March' 27, 190e,

Application filed November 2, 1903. Serial No. 179,455.

I all wrtom it mag concern.-

Be it known that I, EUGENE A. THOMAS, a

citizen of the United S'tatesxresidirig at Chi-- cago, in the county of Cook and State of Illi no s, have invented certain new and useful Improvements in Carpet Cleaning and Disin- "fecting Machines, of which the following is a specification.

This invention relates to improvements in machines for cleaning and disinfecting textile fabrics, carpets, rugs, and the like by coinpressed air or steam impregnated with adisinfectant.

Among the objects of the invention are to provide a sim le, strong, and durable apparatus of this 0 aracter which will be efficient in its operation and by the use of which a single attendant will be able to readily handle, clean, disinfect, and renovate carpets, rugs, and other textile fabricsof almost any length. The width of the apparatus will of course art as a limitation upon the width of the carpets and rugs which may be cleaned therein; but

it is entirely practicable to construct a ma chine which will take any width of carpet.

The invention consists in the matters hereinafter set forth and particularly pointed out in the claims.

In general terms a carpet-cleaning apparatus embodying my invention in its pre-. ferred form comprises in its construction a carrier consisting, preferably, of link belts adjusted to sprocket-wheels secured to shafts revolubly mounted in suitable bearings'in the machine-frame and provided at intervals with suitable transverse slats upon which the carpet or other article is supported. This carrier 1s supported in a substantially horizontal position and is of considerable lengthsay, for example, twenty-five feet. The cleaning instrumentalities comprise, primarily, one or more air-jets supported above the carrier, adapted to )roject a jet or jets of air downwardly upon t e carpet on the carrier at any inclination desired, air being sup plied to said jets through connection with a source of supply of air under pressure. Preferably, also, the cleanin instrumentalities comprise, in addition tot 1e above jet or jets, a fjet or jets which extend transversely there- 0 directly beneath the upper lap of the car rier and adapted to project a jetor jets of air upwardly against the under surface of a carpet or other article supported on said carrier.

in advance or said jets, adapted to run in 'contact with the u per surface of a carpet or other article an ,mopposite direction to the movement of the carpet, which brush operates to loosen and raise the pile ornap of the article, so as to allow the air-jet to penetrate the same more'easily and thoroughly: The carrier and cleaninginstrumentalit-ies are illclosed within a suitable casing, preferably made of sheet metal, which is designed to confine the dust and dirt expelled from the carpet or other article being-cleaned. The bot.

tom of'the casing is trough-shaped and declines toward an outlet-opening, and the interior of the casing beneath the carrier is' designed to he s r'ayed with water from a suitable system 0 pipes provided for the purpose, whercbv the dust and dirt expelled from the carpetb Y the jets of compressed air will be caught or preclpit-ated by the spray and carried. off by the current of water through the outlet opening, which may be connected with the sewer or other drainage system. This may be effected by a pipe of diameter sufficient for the purpose, with perforations of a size and at distances as may be desired or required, extended'across the up er end or head and alon the sides oft ie casing slightly raised above the bottom thereof and connected at the front or u some. water-supply with sufficient pressure so that the water discharged through the erforations in form of jets or spray will t oroughly wash out all dust and dirt that mayor shall fall to the trough-shaped bottom of the casing and carry the same out through a a pipe at the lower end of the casing and into the pipe leading from the fan through which the dust is expelled, precipitating the dust and carrying it in a muddy stream, so ion as there is any dust, into the sewer or at or drainage system.

In the operation of the machine it is designed that one or more of the carrier-.

supporting shafts will be positivel driven through connection with anysuitab e source of power and in such manner that the direction of rotation of said shaft can be reversed as desired. A section of the casing-wall inclosing the front end of the carrier is made removable, comprising, preferably, a hinged sectionor door which may be, opened to permit access to the carrier for the purpose of attaching the carpet or other article thereto and through which said carpet m rug is drawn into the casing and removed there;

Mini r er end with machine.

from. Power being applied to the carriershat't to impart movement thereto in the m per'direction, the carpetor other article w be drawn into the machine upon the up ne lap of the carrier and willbe e. osed to theaction of the brush and blast rom the arnjets. The air-jets supported above the c rrier are preferably directed rearwardly at an acute an le, so that the blast will natuany reboun from the surface of the carpet, thus tending to blow the dust and dirt upwardly-out of the carpet rather than to force it down into and through the car et, as would be the case were the jets directedhit ri ht angles to the surface of said carpet. T e can ier movement is continued until the entire ength of the carpet has been subjected to the action of the brush and air-jets, the forward end of the carpet when of considerable len th passing around the end of said carrier an moving rearwardly with its lower lap until the entire length thereof has been resented to the action of the brushes and ets. The direction of movement is then reversed and the carpet drawn back past the air-jets and removed. A sin is complete exposure of the car et to the action of the air-jets while moving oth forward and backward past them should suffice to thoroughly cleanse and renovate the' same. All of which will be more fully understoodfrom the following detailed description, illustrated in the accompanying drawings, in which-* Figures 1, 1, and l together form a general view, partly in side elevation and artly in section, of a carpet-cleaning machine of my invention. Figs. 2, 2", and 2 together form a top plan view of a machine of my invention, the casing'being removed from one side thereof to show the operative parts of the Fig. 3-is a transverse vertical sectional view on the line 3 3 of Fig. 2. Fig. 4 is a side elevation of a part of one of the airjets. Fig. 5 is a transverse section taken on the line .5 s of rig. 4. Fig. 6 is a detail view of part of the front edge of the clamp for gnsping the article to be cleaned. Fig. 7 1s a plan view of said clamp complete attached to one of the-slats of the conveyor; Fig. 8, a detail cross-section through one of the slats of the conveyer, showing part of the chain carrying the same; Fig. 9,-a detail vertical section showing the manner in WhlCh the shaft at the rear end of the carrier is braced at its middle; Fig. 10, a detail view of one of the rubber brushes; Fig. 11, a detail view of one of the journal-boxes supporting the ends of the end shaft of the carrier. Fig. 12 is a detail sectional view of the ivotal connection between the supplemental last-pipes 28 and 2 l The frame of the machine consists of longitudinal frame members 1,which extend continuously the entire length of the machine at each side thereof, transverse frame 'tudinal of said machine.

members 2, which connect the longitudinal frame members 1, and legs 3-, upon which the longitudinal frame members 1 are su ported.

During the operation of the maciime the carpet or other article to be cleaned, disinfected, and renovated is supported upon a carrier (indicated as a whole by A) mounted upon the Inachine-frame in such manner as to be freely movable in both directions longi- As shown, said carrier consists of transverse slats 4, secured at intervals to link belts 6, adjusted to sprocketwheels 7, secured to shafts 8, revolubly mounted in suitable bearings on the longitudinal frame members l,sa1d shafts 8 being provided at such intervals that the upper ap of the carrier will be su ported substantially level. To prevent t he end shafts 8 from springing under the strain to which they are subjected, which would allow the carrier to sag, said shafts are provided with one or more bearin s in suitable rigid subports intermediate t e end bearings thereof. As shown, the intermediate bearings for said end shafts are formed in bars 9, which are supported in fixed longitudinal adjustment by means of braces or truss-rods 10, the ends of which are secured to the longitudinal frame members 1 and against which the inner ends of said bars 9 bear.

To provide for ti 'htening the carrier A, either in adjusting the same in the first instance or to take up wear or stretch thereof, the bearings of one or both of the end shafts S are adjustable in the direction of the length of said carrier. As shown, the rear shaft only is thus adjustable, the outside or end bearings and tlie intermediate bearings being adjustable independently of each other. To effect desired adjustment of the outside or end bearings of said shaft, said bearings are, as shown in Figs. 2 and 11, formed in blocks 11, slidabl Y mounted on base-plates 12, secured to the longitudinal frame members 1, and are adapted to be forced outwardly by thrust-screws 13, threaded throu h lugs 14 on said base-plates. To provide or desired adjustment of the intermediate bearing or bearin s of said shaft, the ends of the truss rod or race 10 instead of being secured directly to the lon itudinal frame members 1 are secured to bl ocks 15, slidably mounted on base-plates 16, secured to said longitudinal frame members 1, and adjustment of said blocks 15 is effected b means of thrustscrews 17 in substantialfy the same manner as adjustment of the biocks 11 is effected. The blocks 11 and 15 are secured in desired longitudinal adjustment by means of suitable clampin bolts or screws.

The lower ap of the carrier A is supported upon drums or rollers 18, revolubly mounted in suitable bearings in the machine-frame. Said rollers 18 operate to relieve said carrier from the strain due to its own wei ht and cOntinuouSly the entire length thereof.

also prevent sagging of the carpet or other article when it passes onto the lower lap of said carrier.

Supported above the upper lap of the carrier and, extending transversely over the same are one or more airjets 19, adapted to project air downwardly .uponthe carpet or other article supported upon said carrier, as

shown in Figs.,1 2, 2", 4, and 5.

My invention contemplates the use of any desired or approvedform of air-jet. Iprefer, however, to use the form of jet shown in detail in Figs. 4 and 5 of the drawings, con prising' a" tubular chamber 20 and a lateral chamber 21in open communication therewith,

by means of a justingsscrews 23, and any de-' sired width of discharge-opening may conveniently be provided by inserting washers 24 of desired thickness-say one sixty-fourth of an inch:between the sides of said dischargeopening; 1t isobvious that the width of the discharge opening may be varied as desired byusing washers of different thicknesses.

The air-jets 19 are preferably supported in such manner thatthe discharge-openings 22 will be directed downwardly upon the carrier at an acute angle,-rearwardly, and in such manner also that said air-jets will be adjustable toward and from said carrier. In the preferable construction shown said air-jets 19 are provided with rectangular slides 25, referabl formed integral with extensions t ereof, w -ch are fitted to and are freely movable in upri ht. uides or fiways formed in standards or raciets 26'; Supported upon the longitudinal framegrnembers. 1. Vertical adjustment of the air 'jet's 19 is effected by means of screws threaded through the ends of the brackets or standards 2,61 the, lower ends of which'areirevolubly' securgdagainst longitudinal movementin the slides 25,-the relation being such that said air-jetswillfbe properly directed. I f

mental jet or pi e29, which is preferably connected to the pipe or jet 28 at one side of the carrier by a union 30, and which is pivotally connected thereto, so that when desired for use it may be moved pivotally so as to extend transversely of the carrier directly above the upper lap thereof and beneath a carpet supported thereon, so that as the carrier moves the carpet will be drawn over said pipe or jet 29. Said ipe or jet 29 is provided with discharge ho es or openings on its upper side. Thus passing over the same the carpet will receive the full force of the blast therefrom, thereby securing the greatest efficiency of op- The pipe orrjet 29 is designed for and when not desired for use may be turned pivotally so as to extend longitudinally of the machine at one side of the carrier, as shown in Fi inwhich position it will not obstruct c. d, I 0 said carrier. Communication between the pipes or jets 2S and 29 is controlled by. means of a valve '31 in the union 30.

As shown, air is supplied to the

jets

19 and 28 through

pipes

32, 33 and 3,4, which communicate with a header 35, which is connected with a suitable source of supply of air under pressure. The

pipes

32, 33, and 34 are controlled by means of suitable valves, and the pipes communicating with the jets 19 are connected thereto by means of flexible sections, thus providing for desired vertical adjustment of said jets.

In order to render the operation of the blast from the air-jets moreefficient, means are provided for raising or loosening the pile or nap of the carpet beforeit reaches said jet. As shown, said means comprise brushes 36, revolubly mounted in suitable bearings in front of the air-jets 19. The brushes 36 are preferably adjustable toward and from the carrier A. To provide for such adjustment, the bearings for said brush are formed in guides 38, formed in brackets or standards 89,

ICC

boxes 37, fitted to and freely movable in bers 1. Ad ustment of said brushestoward and from the carrier is effected by means of screws 40, threaded through the ends of the brackets or standards 39, the lower ends of which are revolubly secured a ainst longitudinal movement in the bearin rboxes 37. R0- tation is imparted to the brushes 36 by means of drivingconnection with a suitable source of power. When the brushes 36 are depressed so as to run incontact with the surface of a carpet or other article supported on the carrier, they will obviously operate to loosen and raise the pile or nap of said carpet, thus allowing the blast from the air-jets to penetrate said car et more easily and thoroughly, rendering the operation ofsaid jets much more efficient:

The carpet or other article to be cleaned maybe attached to the carrier in any desired manner. Preferably, however, the connec- [10 between said carpet and carrier will be elastic, thereby permitting the carpet to adjust itself to variations in the travel of the carrier, as in turning around the end of the carrier from one lap to the other thereof, without subjecting said carpet or other arti cle to any undue strain or tension. A desir able form of attaching device is that shown in Figs. (5 and T of the drawings, coniprising a clamp 42. adapted for attachment to the edge of the carpet, and a clip 43, adapted for attacluuent to one of the slats 4 ol the carrier A, connected by means of a spring-link 44. As shown, the'jaws of the clamp 4'. are adapted to he lirml set upon the carpet by means of clamping-screws 45, and the clip 43 comprises a hinged member 46, adapted to'be secured in closed position around one of the carrier-slats 4 by means of a cotter 47. Any desired number of fastening devices may be used necessary to properly connect said carpet to said carrier.

Preferably also, my machine comprises means for holding the carpet or other article llat upon the carrier A while being cleaned and for preventing sagging of the carpet when it passes onto the lower lap of said carrier. As shown, said means comprise cords 4 one end of each of which is attached to the carrier A and the opposite end thereof to a positivelr-ilriven drum 49, the connection neing such that the surface of the drum 49 will move at the same rate as the carrier A, and the driving connection being such that, as the points of attachment of said cords to said carrier move awa from said drum the cords 45' will he unwound therefrom. and vice versa. shown in Fig. 1, the drum -19 is driven from the front carrier-shaft by means of spur-gears i) ll. Preferably, also,thc cords in are attached to the carrier A by means of spring-links 5t) which all'ord elastic connection between said cords and carrier, thereby permitting said cords to adjust tl'iemsclves to slight \ttl'iutlons in the travel of said carrier, as when passing around the end thereof. 'ith the described construction it is obvious that as the cords 48 are drawn oil from the drum 4!) they will lie flat upon the carrier A or upon the carpet or other article supported thereon and being at all times under considerable tension will operate to hold the carpet llat and will also prevent sagging of the carpet on the umer lap of said carrier. As they prevent sagging of the carpet or other article awav from the lower lap of the carrier when the carpet is carried around the far end of the carrier, it is obvious that the drums or rollers in and the cords wiii suppiemciit each other.

'lhe carrier A. the cleaning instrumentalitics, and other operative parts of the machine are inclosed in a casing 51. which is preferably made ol' llt'tl metal swim-ed to a framework consisting of T-bars 52, supported upon the longitudinal frame members 1. The cusing 51 is provided at its forward end with a hinged section or door 53, as shown in Figs. 1 and 2, through which carpets and the like may be drawn into and removed from said casing in the operation of the machine. -At its rear end it is contracted, so as to make a communication, preferably by a hollow cylinder 57", with an exhaust-fan 57, and beyond the fan and connected with the chamber in which it revolves a connection 57", preferably tubular, is extended to a union with the discharge-pipe 54 from the bottom of the casing, wl'iereby by the revolution of the fan a draft. is created, drawing the dust blown from the carpet or other article and expelling the same through the extension-pipe leading from the fan into the discharge-pipe from the outlet-opening of the casing, wherein it is precipitated by the water flowing through said discharge-pipe and washed into the sewer or other drainage system. The bottom of said casing is trough-shaped and declines from the front end toward a discharge-opening 54 at the rear end thereof, so that water admitted to said casing will drain off through said opening.

Supported within the casing 51 below the carrier A is a pipe 55, which communicates with a suitable source of waterrsupply. The supply of water to said pi e 55 is controlled by means of a valve 56. he pipe 55 is provided at short intervals with small holes or openings designed to discharge a fine spray into the casing 51, which will operate to precipitate or wash down the dust and dirt expelled from the carpet and other articles by the airblast in cleaning the same intothe trough, whence it will escape through the discharge-opening 54.

An exhaust-fan 57, which communicates with the rear end of the casing 51, operates to create a draft and expel dust and dirt from said casing not removed by means of the spray.

To provide for disinfecting the carpet after cleaning the same, a tank 58, designed to contain a suitable disinfecting solution, is connected with the header 35 by means of a pipe 59, controlled by a valve 60. The contents of said tank may be heated to any desired degree by a steam-coil 61 at the bottom thereof, which coil is perforated and connected with a source of steam-Suppl by. a pipe 62, controlled by a valve 63. Io disinfect the carat, the supply of air is shut off from the lieader 35 and the valve opened, thus admitting steam impregnated with the disinfectant from the tank 58 into the: header 35, whence it is discharged into the casing 51 through one or more of the air-jets. In practice l pref er to admit the-disinfectant through the rearmo'st jet 19 in order that the least possible amount of disinfectant may escape through the door 53 in the front end ol thicasing. After the carpet has been exposed i to the action of the disinfectant a desired length of time the valve on is closed, shutting off the supply from the tank 58; or it u'eferred, steam impregnated with the (hem ectam. may be, by the means shown, in ected into the header 35 while the air-blast is on, thus hcatiu" the air to any desired degree, and then t e same discharged so impregnoted with the disinfectant u on the article to be cleaned and disinfcctet as above dcscribcd, thus cleaning and disinfecting the carpet or other material simultaneously w th the same blast. To avoid the condensation of the steam impregnated with the disinfectant when dischar ed into the header, the an may of course be eated by any suitable additional means, thereby increasing the ciliciency and force of the compressed air; or instead of using an air-blastto carrv the disinfectant in steam may be employed, as stated, into which may be introduced directly the requisite amount of the disinfectant by the means shown or any other suitable means, and whereby the car et or other material ma be cleaned and disinfected at the same time and by the same blast of steam im regnated with the disinfectant.

he carrier A is driven from any reversible source of power (not shown) by a belt applied to a pulley 64, secured to an extension of the front carrier-shaft.

The rocess of cleaning a carpet or other article y means of a machine of my invention is as follows: The 1))Qlt1i0l opens the door 53 at the front end 0 the casing 51 and attaches an edge of the carpet or other article t0 the carrier A, preferably by means of the clips described. The door 53 is closed and movement is then imparted to the carrier in a direction to draw the carpet or other article attached thereto into the casing and beneath the brushes 36 and past the

airjets

19 and 28, movement being simultaneously imparted to all other requisite and connected cleaning instrumcntalities. hen the entire length of the carpet or other article has assed the cleaning instrumentalitics in the orward movement of the carrier, the movement of the carrier is reversed, thus rcturning said carpet or other article to the door 53, through which it will be removed.

It is obvious that the rearward movement of the carrier will expose the car et or other article to the action of the c caning instrumentalities a second time. Ordinarily the two exposures of the carpet or the like to the action of the cleaning instrumcntnlities will thoroughly cleanse it, but if it is very dirt v the process may berepeatcd as often as may be deemed necessary.

Durim the o NTttilUll of the cleaning inst rnmcntalities the dust and dirt expelled from the carpet or the like thereby is either washed down by the spray- I from the pipe 55 or is drawn out ol the casing by the exhaust-inn 57, thus preventing an accumulation of dust and dirt within the cus ingfil. Al'tcr thccm'pct has been lhoroughl) cleaned the air is shut off from the jets, the exhaust-fan 57 is stopped, and steam i|n1. rcgnoted with disinfectant is admitted to the casing 51 from the tank 58 in the manner heretofore dost :ibcd. 'lhis finishes the cleaning and disinfecting and renovating operation, and the carpet or other article may he removed fl! on the machine.

With the apparatus described not only car cts and ro s, but llluttlbhSOS, blankets, am other simi ar articles or textile fabrics, may be readily and thoroughly cleansed, disinfected, and renovated with a minimum of labor and in an exceedinglv short time.

It will of course be understood that various changes may be made in the details of the construction shown without departure from the s irit of the invention.
