CARL SCHARRER, OF IIEIDENHEIlVLON-TIIE-REN Z, GERMANY.

CARPET-CLEAN ER.

SPECIFICATION forming part of Letters Patent No. 559,498, dated. May 5, 1896.

Application filed February 28, 1895. Serial No. 540,012. (No model.) Patented in France Julyl, 1893, No. 231,524; in Germany July 13,1e9auo. 75,007,2man1 England my 14,1893,N0.1s,718.

To @ZZ whom, it may concern.'

Be it known that I, CARL SOHARRER, a subject of the German Emperor, and a resident of Heidenheim-on-the-Brenz, Germany, have invented certain new and useful Improvements in Carpet Cleaning Machines, (for which I have obtained Letters Patent in Germany, No. 75,007, dated July 13, 1893; in France, No. 231,524, dated July 13, 1893, and in Great Britain, No. 13,718, dated July 14, 1893;) and I do hereby declare the following to be a clear and exact description of the invention.

My invention has relation to machines for finishing or cleansing textile fabrics, felt, paper, and similar material in web or sheet form; and it has for its object the provision of means whereby the efficiency of these machines is materially increased and the labor involved considerably reduced, as will now be fully described, reference being had to the accompanying drawings, in which- Figure 1 is a vertical sectional view of a iinishing or cleaning machine embodying my invention, and Fig. 2 is a horizontal section of said machine.

Similar letters of reference indicate like parts wherever such may occur in the figures of drawings just" described.

The essentialelements which constitute my invention consist of an airblast arranged to subject both surfaces of the fabric to a blast of air, a dust-collector combined with such air-blast and connected with a suitable exhaust apparatus, and a windingbeam or roller for the nished and cleansed fabric.

The air-blast apparatus is composed of two supply-pipes 7", having suitable branches connected with the opposite ends of two blastpipes cl, which in cross-section have the form of twyers or jet-nozzles, as shown in Fig. l, said nozzles being arranged so as to converge and direct the blasts of air issuing from the nozzle orifices or slits c downwardly upon opposite sides of the web of material G'along coincident lines, (theweb traveling in the direction of arrow p, Fig. 1,) for the purpose of preventing all undulating or napping movement of said web, the jets of air acting in op position to each other, thereby maintaining the web of material in a normally straight line. Below the orifices or slits c of the nozzles CZ I arrange a dust-collecting chamber K', through which the web of material is guided, the inlet-slot a of said chamberbeing formed by two converging inwardly-projecting and more or lesselastic plates a, that hug the web of material from opposite sides, not only for the purpose of preventing escape of lint or other ber, dust, dac., from the chamber K', but also to act as deflectors for the jets of air issuing from the blast or jet nozzles d, said chamber having an outlet-port on each side of the inlet-slot a', said ports being connected through pipes with any suitable exhausting device.

The outlet t for the web of material has the form of a funnel or inverted cone in crosssection, forming a comparatively narrow slit or slot b', through which the web of material passes, and thence between the blast-nozzles c to a guide-roll b4, and finally to a winding roll B. As shown in Fig. 1, the nozzles c project into the funnel-shaped outlet t and lie very close to the sides thereof, the parts operating on the principle of the injector, so that the blast of air cannot be diverted from the dust chamber or collector K.

It will readily be seen that by means of the construction and arrangement of devices but an insignificant amount of lint or fiber or dust will escape into the room in which the apparatus is installed, so that the health of the attendants is not injuriously affected. Furthermore, but little labor is involved in attending to the machine.

The revoluble elements to draw the material through the machine may be driven in any suitable manner, as by belt-pulleys or chain or other gearing, from any desired motor.

It will of course be understood that the blast-nozzles are of such a length as to act upon the whole width of the web of material.

For thoroughly cleaning woven fabric, such as carpets and the like, the same before passing the apparatus above described may be subjected to an energetic beating action, preferably to an alternate brushing and beating, which may be eected by hand or in any other desired manner.

-Having thus described myinvention, what IOO I claim as new therein, and desire to secure by Letters Patent, is

l. In a machine of the class described, a dust-box having a slot in its top and bottom diametrically opposite each other, upwardlyconverging iiaps or plates one on each side of the bottom slot forming a partition within the box, a dust-guide funnel-shaped in crosssection projecting from the upper slot, a suction-port in one of the vertical walls of the dust-boX on opposite sides of the partition, and means for passing a web of material upwardly through the slots, in combination with two downwardly-coverging blast-nozzles ai ranged above the dust-box with their orifices within the. dust-guide and in the same plane and forming between them a passage for the aforesaid web, substantially as and for the purpose set forth.

2. In a machine of the class described, a dust-box having a slot in its top and bottom diametrically opposite each other, upwardly converging resilient or yielding iiaps or plates one on each side of the bottom slot forming a partition within the box having inclined outer faces, a suction-port in one of the walls of the boX on each side of the partition, a dustguide, funnel-shaped in cross-section projecting from the upper slot, and means for passing a web of material upwardly through the slots; in combination with two downwardlyconverging blast-nozzles arranged above the dust-box with their orifices in the same horizontal plane within the dust-guide and forming between them a passage for the aforesaid web, substantially as and for the purpose set forth.

In testimony whereof I havehereto signed my name in the presence of two witnesses.

CARL SCIIARRER. Vitnesscs:
