MATTRESS SCRUBBER Filed Nov. 3o, 1943 Patented Sept. 25, 1945 UNITED STATES PATENT OFFICE VMATTRESS SCRUBBER Fred E. Hays and Lawrence O. Scott, San Jose, Calf.

Application November 30, 1943, Serial No. 512,398

Z Claims.

In the operation of cleaning plants, it is common practice to clean mattresses by means of a suitable cleansing liquid and a small scrubbing tool which the operator laboriously works over the surface of the mattress, first going over one surface, then laying the tool aside while he turns the mattress preparatory to similarly scrubbing the other side. When there are a large number of mattresses to be cleaned this is a slow and laborious process requiring the employment of many operatives and the duplication of the devices used.

It is, therefore, one object of the present invention to provide means for cleaning mattresses quickly and thoroughly, and in such a manner as to require a minimum amount of manual labor.

It is also an object of the invention to provide means of the character indicated that will obviate the necessity of turning the mattress to clean both sides thereof, and one that will clean mattresses cf varying thickness with equal facility.

Furthermore, it is an object to provide means of the character indicated through which mattresses may be passed in rapid succession and thoroughly cleaned without other attention than the proper positioning thereof.

Finally it is an object to provide means of the character described that will be simple in form and construction, economical to manufacture, strong, durable and highly efcient in its practical application.

In the drawing:

f Figure 1 is an end elevational View of a machine embodying our invention, with parts broken away.

Figure 2 is a view on line 2-2 of Figure 1.

Figure 3 is a top plan View of the structure shown in Figure 1.

Figure 4 is a detail section on line 4 4 of Figure 1, greatly enlarged.

In the specific embodiment herein disclosed we show at I-I two tables supported in any suitable manner on the same horizontal plane but spaced apart at their opposing ends by means of a vertically disposed framework 2 which extends the full width of the tables as shown. The two ends of the framework 2 are constructed and arranged to form vertical parallel tracks as at 3 and 4.

At 5 is shown a carriage extending the length of the framework 2 and provided with wheels as 6 and 'I on its two ends by means of which it may be moved vertically on the

tracks

3 and 4. Carriage 5 is suspended above the level of the table tops I--I by means of springs 8 connected there- Civ to and to a plate 9 on the top of the framework 2.

A cylindrical brush IU is shown mounted to rotate in bearings as II on either end of the carriage 5, this brush being positioned so that its working surface will rotate below the horizontal plane of the bottom of the carriage 5, and the length of framework 2.

The brush IIJ is rotated in the direction of the arrow I2 by means of the sprocket and chain drive I 3 to the motor I4 on carriage 5.

At I5 is shown a brush similar to the brush III and mounted directly below the same to extend slightly above the plane of the tables on bearings II on framework 2 and in parallel relation to brush I9. This brush is rotated in the direction indicated by arrow I1 by means of sprocket and chain drive I8 to a motor I9 on framework 2,

The washing liquid is applied to either side of the mattress by means of pipes as 20 and 2| lying .parallel with the tables I-I and mounted on the framework 2 as at 22 both above and below the plane of said table. Spraying nozzles as 23 are aixed to the said pipes in opposed relation to each other as shown. The liquid is fed to the pipes from a source of supply not shown and is controlled by means of a valve at 24.

With the spraying nozzles in operation and the brushes rotating as described, a mattress is laid on the table I, on the side opposite to the direction of rotation of the two cylindrical brushes, and shoved along the same in the direction of arrow 25. As the mattress moves between the two sets of nozzles it is thoroughly sprayed with the cleaning liquid and moved on until it passes lthrough the space between the two brushes, the Iupper brush and the cage upon which it is mounted being forced upwardly as the thickness of the mattress requires. Since the movement of the mattress is manually controlled and the brushes rotate at relatively high speed, the said mattress may be moved slowly or momentarily held stationary if desired to more thoroughly scrub badly soiled spots.

Although but one specific embodiment of the invention has been herein illustrated and described, it will be understood that various alterations in the details of construction and mode of operation may be made without departing from the scope of the invention as indicated in the accompanying claims.

We claim:

1. A machine for scrubbing mattresses comprising, a supporting means providing a pair of horizontally disposed table tops and a vertical framework disposed between their opposing ends and extending thereabove, a cylindrical brush mounted on the framework in parallel relation with the table tops, the work contacting portion of the brush extending above the plane of the table tops, and means for rotating said brush, a carriage mounted for vertical movement in said framework and springs connecting said carriage withthe upper portion of the framework to support the carriage, a cylindrical scrubbing brush rotatively mounted on the carriage in opposed and parallel relation with the rst mentioned brush, driving means for the second brush mounted on the carriage, liquid conveying pipes mounted on the framework above and below the table top level and adjacent said brushes, and spray nozzles mounted on the pipes to spray liquid on both sides of the mattress prior to its passage between the brushes.

2. A machine for scrubbing mattresses and the like comprising, a supporting means providing a pair of table tops disposed in substantially the same horizontal plane and a Vertical framework disposed between their opposing ends and extending thereabove, a cylindrical brush mounted on the framework in parallel relation with the table tops, the work contacting portion of the brush extending above the plane of the table tops, and means for rotating said brush, a carriage mounted for vertical movement in said framework and sprin-gs connecting said carriage with the upper portion of the framework to support the carriage, a cylindrical scrubbing brush rotatively mounted on the carriage in opposed and parallel relation with the first mentioned brush, and driving means for the second brush mounted on the carriage.
