CLEANING DEVICE.

Application led May 28,

A further object of my invention is to provide a. device of the type described which has cleaning members constructed to efficiently clean the various types of fabric.

A further object of my invention 1s to provide a device of the type described .which has automatically controlled means for stop-1 ping the rotation of the device at a predetermined point. A further object of my invention 1s to go provide a device of the type described which has novel means for automatically releasing the fabric that is being cleaned as the rotation of the device is stopped.

Other objects and advantages will .appear g5 in the following specification, andthe novel features of the invention will be particularly pointed out in the appended claims. p

My invention is i'llustrated in the accompanying drawings, forming part of this ap-` plication, in which Figure l is a front elevation of the device, Figure 2 is an end elevation of the device, Figure 3 is a fragmentary perspective view of the device, Figure 4 is a` section along the line 4-4 of Figure 1, and Figures 5, 6, 7 and 8 are fragmentary portions of the device.

In carrying out my invention, I provide

sup orts

1 and 2 having adjustable bearings 3 t erein which are adapted to receive a shaft 4. A drum 5 having a groove 6 disposed longitudinally therein is rigidly mounted upon the shaft 4 betweenv the

supports

1 and 2. The upper ends of the sup-

D ports

1 and 2 are provided with bearings 7 and 8 in which stub shafts 9 and 10 are res ectively disposed.

rackets 11 having are rigidly mounted upon thestub shafts 9 and 10. Shafts 13 which are provided with clutch 'ends adjacent the support 2 are rotatably disposed in the bearings 12.

Cylinders

14, 15, 16, 17 and 18 are rigidly mounted upon the shafts 13 between the brackets 11.`

An object of my invention is to providea.

y bearings 12 equally spaced around the outer edge of the brackets 1926. Serial No. 112,346.

The cylinder 14 is provided with spirallydisposed rubber sponges which are especial-` ly adapted to clean opaque shades, or the like. The cylinder 15 is provided with spirally-disposed squeegees.`V The cylinder 16 is provided with spirally-disposed relatively soft bristles. The cylinder 17 is provided with' spirally-disposed bristles 19. The cylinder 18 is provided with spirally-disposed felt strips.

In Figure 3, I have shown a fragmentary view of the cylinder 17 and the manner 1n` which the bristles 19 are secured thereto.

The cylinder 17 is provided with a plurality of spiral grooves 2O into which U-shaped sections 21 are disposed. placed across the upper edges of the U-shaped sections 21, and small Ushapedsections 22 are placed upon'the bristles and moved inwardly and secured in place by screws 23.v

The bristles 19 are now in the position shown in Figure 3. rihese sections are disposed in each of the grooves in the :cylinder 17 from one end thereof to the other. The Sponges, squeegees, soft bristles, and `felt strips are secured to their respective `cylinders in the same manner in which the bristles 19 are secured to the cylinder 17 The stub shaft 9 has a groove therein which is adapted to receive a hand lever 24. The hand lever 24 is pivotally mounted upon t-he stub shaft 9 by means of a pin 25. The

hand lever is provided with a fork-shaped end 26 having inwardly extending pins which arereceived in an annular groove of a stop pin 27. The free end of the stop pin 27 is receivable `in openings. 2S which are equally spaced in a eircuitous path within the support 1, seeFigure` 2.

The drum and cylinder-actuating mechanism is composed of a drive shaft 29 which is provided with a rigidly mounted pulley 30 and a loosely mounted pulley 31. A clutch 32 isAV keyed to the inner `end of the shaft 29 and is actuated by a hand lever 33. A beveled gear 34 is rigidly mounted upon the shaft 29 and ,is in mesh witha pinion 35. rlhe pinion 35 is rigidlymounted upon a shaft 36 whichcarries a worm 37. A clutch 38 is disposed beneath the worm 37 and is adapted to engage and disengagethe worm 37 `with `and from the shaft 36.` vA forked lever 39 is pivotallyniounted at 40 upon the support 2 and is provided with a roller 41. The forked end of the lever 39 straddles the clutch 38 and is provided with The bristles 19 are` inwardly extending pins which are adapted to Vengage with the clutch. Aleaf spring 43 is mounted upon the end of the drum 5 and, is adapted to engage with `the roller 41.

Spring-pressed fasteners 44 disposed upon each end of the drum adpicent the groove 6, and are adapted to rigidly hold a roller of a windowcurtain, or anysuitablef means for securing a fabric to the drum 5. Luge` are integral'with the

supports

1 and 2, and are adapted to engage with` the spring-pressed fasteners 44 and automati-` cally disengaae them from the curtain roller,

or other fabric-holding means.

A pipe 46 is disposed longitudinally above the drum 5 and is provided with a plurality of openings forpermitting a cleansing fluid to be sprayed upon the fabric. A pipe `47 which is in communication with a water supply is provided with a plurality of openings and a valve 48 for turning on and shutting oil' thel water supply. By turningon the valve 48, the water is forced through. the openings and upon `the fabric which ison the roller 5.

From. the foregoing description of the various `parts of the device, the operation thereof may be readily understood. Let us4 assume that the operator wishes to' clean an opaque window shade. The shade is first unrolled and a roller placedin the groove 6 of the drum 5 and rigidly securedin place by the spring fasteners 44. The lever 24 is then forced inwardly, releasing` the'pin 27" and turned in either direction until the roller 14 is brought into vertical'` alignment with the shaft 4. The lever 24 may then be moved outwardly causing the pin 27 to be forced into the adjacent opening 28. The drum 5 may be moved toward or `away from the roller 14` by means of the adjustablebear ings 3. n. ,4 The lever 33 is now actuated causingthe clutch 32 to engage with the clutchend `of the shaft 13 upon which the roller 14 is mounted. Then power is'V applied to the shaft 29, the roller 14 is rotated at a rela`- tively fast speed. The lever 39 is actuated by forcing downwardly upon the end carrying the roller 41 thus causing the clutch 38 to engage the'worm 37 with the shaft 3C. and in this manner, the drum y5 is rotated at a relatively slow speed. As the drum rotates the shade `engages with the drum and is held in frietional engagement therewith.

When the drum 5 reaches the end of a revolution, the leaf spring 43 wil] `engage with the roller llaiidcause the lever 39 to disengage the worm gear 37 from the shaft 36.

spring fasteners 44and release them from ing said drum at a relatively In this n'ianner, the power is cut off frein` the drum 5 and the engagement of the spring the curtain roller. The operator may readily remove the curtain from the drum if it is thoroughly cleansed. If the curtain is not thoroughly cleansed, the fasteners may be engagedivith the roller again and the power To applied to the drum and to the roller 14 for another revolution of the drum 5. At the end of each revolution, the power is released automatically from the drum 5, the saine releasing means serving as a stop for the drum, 'I5 and the fastenersael autoimitically.released. The shade may now be removed from the drum, turned over, and secured-to the drum` again for cleaning the other side` ofthe 24 may be 8U wrink shade.
