1 Claim.

This invention relates broadly to dry-cleaning machines, and more particularly to improvements in the revolving cylinder for such machines.

As is well known in the art, in dry cleaning a naptha, in a dry state, is used, being placed within a revolving cylinder in which the garments, or the like to be dry cleaned, are placed. As the cylinder revolves, the garments thereof are subjected to action of the agitated naptha for eiecting a cleaning of such garments.

At the present time, after being so subjected to the naptha, the garments are taken out of the cylinder and brushed to remove spots.

In accordance with the present invention this latter step is obviated, there being, in accordance Y with the present invention, brushes arranged in the cylinder to supplement the action of the naptha in eiecting a dry cleaning of the garments and at the same time subjecting the garments to a brushing action as will remove spots therefrom. Consequently when the garments are removed from a cylinder equipped in accordance with the present invention, they are then in condition for ironing and other such work without first being spotted as, so explained above, is

usually the first step in the treating of the garments upon removal of the same from the cylinder.

The present invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings wherein:

Figure 1 is a longitudinal sectional view through a dry-cleaning cylinder showing the same equipped with brushes in accordance with this invention.

Figure 2 is a transverse sectional view through the cylinder with the brushes shown in position therein.

Figure 3 is a transverse sectional view through one of the brushes.

Figure 4 is a plan view of the core of one of the brushes.

Referring more in detail to the drawings it will u f be seen that 5 indicates generally the driven, revolving cylinder of a conventional dry-cleaning machine.

In accordance with the present invention the cylinder 5 is provided interiorly thereof with a series of circumferentially spaced ribs 6 that extend for substantially the full length of the cylinder.

For each rib 8 there is provided a brush indicated generally by the reference numeral 1.

Each brush 1 embodies an elongated core 8 of any suitable material.

The core 8 is substantially U-shaped, or channel-shaped in cross section so as to straddle a rib 6, receiving the rib 6 within the channel 9 of the core as illustrated.

Secured to the core 8 in longitudinal and transverse rows are groups of tufts or bristles l0.

Each brush 1 is secured to its rib 6 in a positive and eilicient manner through the medium oi' screws or other fastening elements Il that pass through the core 8 at opposite sides of the channel 9 and are threaded home into the rib 6 as shown.

It will thus be seen that in accordance with the present invention the cylinder 5 is provided internally thereof with a series of circumferentially spaced brushes elongated longitudinally of the cylinder, and these brushes subject the garments or the like within the cylinder to a brushing operation that supplements the action of the naptha, or other dry-cleaning agent within the cylinder as the cylinder revolves. Consequently in substantially the one operation the dry cleaning and spotting, or in other words the removing of spots from the garments, are accomplished thus reducing materially time, labor, and costs involved in dry cleaning of garments, chair covers, and other articles of a character as cannot, with success, be wet washed or laundered.

It is believed that the invention together with its many advantages will be clear to those skilled in the art without further detailed description.

While I have herein illustrated and described what is considered to be the preferred embodiment of my invention, I am well aware that in practical elds such details may, from expediency or desire, be altered without departing from the spirit of the invention as hereinafter claimed.

Having thus described the invention what is claimed as new is:

In a dry-cleaning machine, a rotary cylinder provided interiorly thereof with a series of circumferentially spaced ribs elongated longitudinally of the cylinder, and brushes removably mounted on said ribs, each of said brushes embodying a core substantially channel-shaped in cross-section and receiving a rib in said channel, and longitudinal and transverse rows of bristles secured to the sides and top of said core, and fastening elements extending through the walls of the cores and securing the cores of the respective brushes to the associated ribs.
