MACHINE FOR CLEANING AND PURIFYING CARPETS 0R OTHER FABRICS.4

SPECIFICATION forming part of Letters Patent No. 407,309, dated July 16, 1889. Application filed February ll, 1888. Serial No. 263,736. (No model.) Patented in England .Tune 8, 1886, No. 7,662.

To all whom, z'z may concern/f Be it known that we, THOMAS VARSOP and ARTHUR SAMUEL WARsoP, bot-h subjects of the Queen of Great Britain, and residents of Nottingham, in the county of Nottingham, England, have invented certain new and useful Improvements in Machines for Cleaning and Purifying Carpets or other Fabrics, (for which we have obtained a patent in Great Britain, No. 7,662, dated June S, 1386,) of which the following is a full, clear, and exact speci- Iication.

This invention relates to an improved apparatus for cleaning and purifying carpets or other fabrics. For this purpose we cause a powerful current of compressed air, divided either into a number of small jets or one or more extended jets or sheets of air, to be thrown onto the carpet or other fabric to be cleansed and purified in such a 'manner that the air is forced completely through the interstices of the carpet or other fabric, and thereby carries with it the dust or other impurities that may be in the carpet into a receptacle made to receive them, and from which they are drawn `away by a Hue, fan, or other means. The carpet or fabric during the operation is drawn by hand or other suitable means slowly over a revolving perforated roller, the curved surface of the roller opening temporarily the interstices of the carpet, and more freely allowing t-he dust and impurities to be forced out. by a powerful current or currents of compressed air from the supply-pipe and nozzles or slots placed immediately over this roller, and to which pipe and nozzles we give a longitudinal reciprocating'motion, so as to more uniformly distribute the air-currents over the fabrics, and thus insure that the full width of the carpet passing over the roller is exposed to the aircurrents. XVe also cause the carpet to pass in some cases under revolving brushes, both before and after being exposed to the air-currents, to further loosen and remove the dust and impurities, which are drawn away from the machine by a fan or other suitable means, the brushes, roller, and air-nozzles being all inclosed in a suitable casing with swing iiap- Figure l is a front elevation of the carpetcleaning machine, partly in section, with the brushes removed. Fig. 2 is an end elevation of the same machine. Fig. 3 is an end transverse sectional view through the line l 2, Fig. l.

Similar letters refer to si m i larparts th roughout the several views.

In the views, A is the frame of the machine, carrying the roller, brushes, ttc., in suitable bearings; also the casing H, in which revolves the wire -gauze roller or perforated drum B, supported by shaft G in bearings J J.

G is the main supply-pipe, conveying compressed air to the several branch pipes G and G2, and thence to the small nozzles L L, which are so formed as each to emit a minute jet of compressed air at their lower extremities.

Each of the pipes G and G2 is fitted with va stop cock and arranged preferably as shown, so that one or more of the sectionpipes carrying the nozzlesmay be shut olf, as

desired, to suit the width of the carpets to be cleaned. These pipes are connected to the horizontal pipe G", supported at the ends within the casing by means of the levers or arms K K, and capable of a horizontal reciprocating motion on the levers K K and axles Y Y, by means of the rod M and eccentric U, driven by the drivin g-pulley N, which also revolves the perforated drum or roller B by the worm P, worm-wheel Q, shaft S, and bevel-wheels V V, as shown.

D D are guide-rollers, over which the carpets pass to and from the machine.

E and E are circular revolving brushes covering the whole length of the machine, and

under which the carpets pass to and from the drum B, their height from which is regulated by the handle X and levers Z Z, the lower eX- tremities of which form bearings F F and in which the shafts carrying the brushes revolve.

These brushes are driven by an elastic band or other suitable means by the pulleys F".

R represents the carpet or other fabric to be operated upon.

l[ is the casing or flue into which the dust and other impurities are forced from the carpets, and from whence they are drawn away by the air-propeller or exhaustiug-fan O, or by other suitable means.

I and l are swing,` or flap doors hinged to the casing, and opened and closed by the handles and balance-weights T T, to keep the dust from lying outside the machine.

The operation of the machine is simple and as follows: The carpet or `other fabric is to be passed over the guide-roller D, under the brush E to loosen the dust, and over the revolving perforated drinn B, Where it is thoroughly cleansed and purified by the compressed air passing' transversely through it from the nozzles L L, then under the brush E, and out of the machine over the guideroller D. XYhen putting,` in and drawing the carpet from the machine, the doors I I are opened by the handles T T, and closed again as soon as the machine is set in motion. The pressure of the revolving' brushes E and E on the carpet is regulated by the attendant by means of the handle X.v After the carpet has been cleaned once it may be again run through the machine if not suiiiciently cleaned. The reciprocating action of the nozzles L L in pipes G and G2 causes the ai r-j ets to be more evenly.distributed over the carpet passing under them.

Having; now particularly described 'the nature of our said invention and in what manner the same is to be operated, we declare that whatwe claim is l. The combination, with the frame, the shaft journaled therein, the casing, and the perforated drum in said casing and carried by said shaft, of the supplypipes, the nozzles thereon, the fan at one end of the casing, the brushes, and means, substantially as de scribed, for revolving said drum and brushes, substantially as and for the purpose specified.

2. The combination, with the frame, the shaft journaled therein, the casing, and the perforated drum in said casing .and carried by said shaft, of the supply-pipes, the nozzles carried thereby, the fan at one end of the casing', the brushes, the levers K K, the axles Y Y, rod M, eccentric U, Worm P, drivingpullcy N, worm-wheel Q, shaft S, and bevelwheels V V, all arranged and operating' sul stantially as and for the purpose specified.

In testimony that We claim the foregoing' we have hereunto setour hands this 230th day of August, 1887.
