KENNETH C. JONES, OF CHAGRIN FALLS, AND JAMES H. JONES, OF CLEVELAND HEIGHTS, OHIO.

RUG-SCOURING MACHINE.

Application filed April 12, 1920.

To all whom i2? may concern:

Be it known that we, KENNETH C. JONES, a citizen of the United States, and resident of Chagrin Falls, and JAMES H. JoNEs, a citizen of the United States, and residentof Cleveland Heights, both residents of the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Rug-Scouring Machines, of which we hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

The objects of the invention are to provide an improved automatically acting machine for scrubbing and cleaning rugs and carpets, by means of which all dirt, dust and impurities can be removed without injury to the fabrics, and the soapy compound with which the fabrics are treated will also be removed by suction, and the appearance of the fabric restored by final brushing.

The invention includes the treatment of the fabrics by means of feeding and soaping rollers, or brushes, followed by treatment with successively operating vacuum cleaners, and completed by the final action of' finishing brushes which restore the pile of the fabric to its original condition.

The invention is illustrated in the accompanying drawings hereinafter more fully described and specifically pointed out in the claims.

In the accompanying drawings Fig. l is a longitudinal section of the device; Fig. 2"

is an end elevation of one end of the pneumatic suction roller; Fig. 2 is a side elevation of the device; Fig. 3 is a side elevation of one extremity thereof; Fig. 4% is a front elevation, on a reduced scale, of the machine; Fig. 5 is a sideelevation showing the gearing which operate the rollers and regulate their relative rates of speed.

In these views A is the frame, B and C are parallel feed rollers the upper one being cylindrical and preferably made of wood, and the other one provided with a flexible feeding surface, preferably made of fibre brushes, which will pass rugs of varying thickness, at the same time, and while providing a positive feed therefor, will prevent the rugs from travelling too fast.

The rug or carpet is laid upon the platform D and introduced between the feed rollers B and C. From thesev rollers the Specification of Letters Patent.

Patented July Ill, 1922.

Serial No. 373,163.

fabrics are fed to the rotary soaping brush E, which revolves in a tank or receptacle F containing soapy material or other cleaning compound in a fluid state. This soaping brush may travel somewhat faster than the feed rollers. I

Circulating steam or hot water pipes F raise the temperature of the cleaning material to the most efiicient point. A second feed roller G provided with a fibre brush surface H, conveys the fabric to the scrubbing brush. T, which is provided with the heavy scrubbing brush J, and revolves in the trough K, through which the dirt re moved from the fabric is conveyed away from the machine. The scrubbing brush revolves at a hi her rate of speed than the feed rollers. Tlatforms L, M and N receive the fabric in turn, from the brushes and it is conveyed upon the platform N to feed roll '0, provided with the fibre brush 0, and over the vacuum roll Q, which is provided with the exhaust cylinders R, having longitudinal suction openings S, S, respectively.

Each exhaust cylinder acts in turn to produce a strong suction at its opening S, as it passes through an arc of about extending from the inner edge of the platform N at T to a point T above the roll V, which is supplied with spaced brushes V, V, and applies the final finish to the fabric. From this finishing roll, it is fed to the delivery table W, and passes out of the machine.

The vacuum in the cylinders is produced in turn as they pass through this are, and the vacuum roll moves faster than the-feed rolls, so that as the suction openings will sweep in succession over the fabric, and clean away the soapy water and dirt left thereon by the scrubbing roll and deliver the fabric freed from impurities, to the finishing roll V. Power is applied to the feed rollers B and C and from these rollers spur gear or other connecting means transmit movement to the other rolls at the relative rates above specified.

These gears are shown in Fig. 5, one train of gears G being above the fabric platforms L, M, and N and the other G" connecting the rolls below the platform.

A vacuum cylinder can, however, be stationary and the fabric can be fed over it, but a revolving roll having a multiple number of cylinders is regarded as most efficient large rug or carpet into the machine,

for the purpose. To prevent the rug from shooting forward too fast as the vacuum roll revolves, and thus preventing the sweeping movement of the vacuum openings over the rug, an endless belt X, travels over the feed roll O,'and over a paralleL-roll O and is provided with points 0 0 which enter the fabric, and hold it back so that it can travel no faster than the feed rolls. The vacuum cylinders are exhausted in turn as they arrive in turn opposite the suction opening Y in the head, and the vacuum ceases at once as soon as this opening is passed. A valve Z normally-closes the suction openings in the cylinders, and a valve stem Z is pushed down by the rug or carpet when the opening passes under it.

A multiple number of suction openings are aligned at each suction position, and the suction openings are staggered, in the respective suction positions, so that when a narrow rug is introduced into the machine, it will press only upon and open the valves in the openings directly under the rugs, thus greatly lessening the area of the suction openings in use at any one time and the vacuum will act only upon the rug passing through, and only the pressure of a very large rug can release all the valves.

A slot or opening A in one end wall of the frame A permits the introduction of a a portion of the rug being treated at a time. Standards A support the separated parts. Having described the invention, what we claim as new and desire to secure by Letters Patent is 1. In a machine for scrubbing rugs and analogous fabrics, feeding rolls, soaping and scrubbing rolls, and a vacuum roll, L

means for driving said feeding rolls at a uniform rate of speed, means for driving said vacuum roll and scrubbing rolls at an increased rate of speed, and a positively engaging feeding device for said rug, adjacent to said vacuum roll, preventing the acceleration of speed of said rug when in contact with said vacuum roll.

2. In a machine for scrubbing rugs, a vacuum roll and means for feeding said rug to said roll, a multiple number of suction chambers in said roll, each chamber having a suction opening and a spring pressed valve in each opening, each valve provided with a rug in pa$ing.

3. In a machine for scrubbing rugs, in combination, feeding rolls for the rug, a vacuum roll, means for driving. the vacuum roll at a higher rate of speed than the feeding rolls, and means for preventing acceleration of speed in the rug when passing over said vacuum roll.

In testimony whereof, I hereunto set my hand this 23' day of June, 1919.
