Application filed August 31, 1911.

To all 'whom it may concern Be it known that we, HERBERT B. SABIN, ARCHIBALD B. TozER, and ARTHUR R. C URTIs, citizens ofthe UnitedStates, and residents of Cleveland, county of Cuyahoga, State of Ohio, have jointly invented a new 'and useul Improvement in Glove-Cleaning Machines, of which the following 1s aspecifi'cation, the principle of the invention being herein explained and the best Inode 1n which we have contemplated applying that principle, so as to distinguish 1t from other inventions. o

The present invention relates to a machine for cleaning articles which are best cleaned by suspension in a solution, which may be a mixture of soap solution and benzin or any simlar liquid. In this type of machines the solution is caused to circulate in a continuous channel in which are placed scrubbing means such as rotating and statlonary brushes and the like, which operate on the articles to be cleaned as the latter are carried by the circulating liquid.

The articles which may be cleaned by our machine are numerous but the specific form of apparatus here illustrated is best adapted to the cleansin of leather gloves and simllar articles. ghe gloves are subjected t0 two separate and distinct cleaning operations, neither of which is alone sufficient to thoroughly clean the glove, but which xtogether produce a most eiiicient result. These two operations are the brushing and the chemical and physical action of the solution upon the gloves. Neither produces indeendently a perfect result but when the dlrt iias been lo'osened or attacked by the cleaning solution, the brushing completes the operation and removes the last trace of dirt.

In the cleaning of delicate material, such as glove leather, it is well understood that not only must the material not be subjected to harsh brushing, but also it must not be treated in any machine having a rough -surface which might come in contact with the leather as the latter is very easily stretched or torn when it is moist. The means which We use to guard against any tearing of the leather consists of a resilient mounting for one of the brushes including means for varying the initial distance between this brush and the other brushes. The distance between the resilient brush and the other Specification of Letters Patent.

brushes will, of course, vary according to the amount of material being treated.

, In order to fully protect the gloves during the cleaning operation, we provide guard members which are placed between'the ends of the brushes and paddles and the casing and are rotated at the Same speed as the brushes and paddles. The guard members will preferably take the form of disks as here illustrated, and will be attached to the brushes or paddles in the manner shown. In this way no gloves or articles in the machine are caught and rolled or otherwise inj ured between the moving brushes and paddles, and the stationary casing walls. The danger of the articles being caught between the moving guard means and the casing may be obviated in several ways. The guarding means are preferably set in recesses in the casing in the manner illustrated.

The annexed drawing and the following description set forth in detail certain mecha nism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.,

Iii'said annexed drawing: Figure 1 is a central vertical section of our cleaning machine taken on the line 1 1 Fig. 2; arid Fig. 2 is a simlar section taken at right angles to the plane of Fig. l and on the line 2-52, Fig. 1.

In Fig. 1, is shown the outer casing 2, and the inner casing 3 thus forming a channel therebgl'reen in which is the cleaning liquid 1, which will fill the casing to the level 4 4. Mounted on the inner casing 3 and approximately level with the walls thereof is a brushing member 5 held by the bars 16 which are pivotally mounted at 17 and supported at the other end by the springs 19. Mounted on a rotatable shaft l() driven from without the casing by a pulley 11 connected with a source of power are brushes 6 which areattached to plates 7. These brushes are adapted to substantially contact the relatively fixed brush 5. At right angles to the sun-face of each brush 6 is a member 8 in the form of a blade or paddle. r[he action of these blades is to cause a circulation of the cleaning fluid around the inner casing. The path of circulation will be guided by the form of the outer casing and will be substantially elliptical, which We have found to Patented Mar. 23, 1915.

manner just described.

give the best efficiency and fewest possible back and eddy currents in a device of this general type.

Before proceeding with the description it will be advantageous to briefly outline the operation. The cleaning liquid is caused to circulate by the action of the paddle blades and the gloves or other articles to be cleaned are thus swept between the brushes which exert a scrubbing action on them. Considerable difficulty has been eX- perienced in keeping thel cleaning liquid, which, is preferably benzin or some similar hydrocarbon mixed with a suitable amount of soap solution, from becoming contaminated with water, which renders the leather articles being cleaned, hard and rough. It is impossible to keep the casing absolutely airtight, and as the rapid levaporation of the benzin tends to cool the solution to a temperature below that of the surrounding atmosphere, the moisture in the latter condenses and becomes intermingled with such benzin in an amount that is harmful in the been found advisable to maintain the cleaning liquid at or above the temperature of the atmosphere. VFor this'purpose a twochambered conduit 24 is conveniently provided connected to the interior of the casing by the conduits`26 and 25. The latter is disposed in the position shown-in Fig. -1 and receives some of the liquid as it circulates from the paddle blades. This liquid will completely fill the conduits 25, 26 and the outer chamber of conduit 24, since these are all below the level of the liquid in the cleaner. A conduit 27 is contained within the conduit 24, forming the second chamber above mentioned, and may be filled with steam or exhaust gas from an engine or fire-box which will to some extent heat the surrounding liquid. The heated liquid will of course rise to the surface, and new liquid will enter at the bottom, caused by the change in the density of the liquid at the different temperatures.

For rapidly collecting the gloves for removal a screen 20 is provided sliding in guides 21 on the sides of the casing. This screen is normally in the position shown in Fig. 1, but can be lowered into the liquid when it will collect the gloves as they are brought around by the circulating liquid. The current is sufficient to hold them against the screen vfrom which they can be removed through the opening 22 in the casing normally closed by the door 23. The rotating brushes are mounted in the casing in an improved way, being attached to disks 9 which are fixedly mounted on the shaft and are set into recesses 28 in the sides of the casing. By this method of mounting no articles can be injured by being caught between the disk and the casing, nor can any It has therefore.

articles be injured between the brushing means and the disks which has been a source of injury to the gloves in other machines.

'ljhe particular form of outer and inner casings here shown may be of course modified considerably, but it has been found that the present form of outer casing having a recurved back 13 to direct the liquid in the direction of arrows 14 is very efficient. The shaft rotates of course in the direction indicated by the arrows 12.

Other modes of applying the principle of our invention may be employed instead of the one explained change being made as regardsthe mechanism herein disclosed, provided the means stated by any of the following 'claims or the equivalent of such stated means be employed.

l/Ve therefore particularly point out and distinctly claim as our invention 1. In a cleaning device, the combination of a casing adapted to receive a cleaning liquid andarticles to be cleaned; means 'adapted to ffcause circulation of said liquid and said articles; and means for collecting said articles during such circulation.

2. In a cleaning device, the combination of a casing adapted to receive a cleaning liquid and articles to be cleaned; means adapted lto cause circulation of said liquid and said articles; and a perforated member adapted to be placed at some point in such circulating liquid, and adapted to retain such articles while permitting the passage of suchfliquid.

3; The combination of a casing adapted to :receive a cleaning liquid and articles to be cleaned; a second casing mounted in said first-named casing and disposed relative to the sides and bottom of said first casing so as to form a continuous passage between said two casings, the plane of such passage being vertical; means for causing a circulation of such liquid and articles lto be cleaned; and brushing means mounted in the path of such circulation and parallel to the surface of such liquid.

4. The combination of a casing adapted to receive a cleanin cleaned; asecon casing mounted on said first-named casing and disposed relative to the sides and bottom of said first casing so as to form a continuous passage between said two casings, the plane of such passage being vertical; stationary brushing means mounted in the path of such circulation and parallel to the surface of such liquid; and other brushing means rotatably mounted about an' axis parallel to said stationary brushing means, said rotatable brushing means being adapted to cause a circulation of such liquid and articles to be cleaned, and to cooperate with said stationary brushing means to cleanthe articles in such liquid.

5. The combination of a casing adapted liquidV and articles to be4 to receive a cleaning liquid and article to be cleaned; a second casin mounted in said first-named casing and is osed relative to the sides and bottom of said first casing so as to form a continuous passage between said two casings, the plane of such passage being vertical; stationar brushing means mounted in the path o such circulation at substantially right angles to the lane of the same and parallel to the sur ace of such liquid; a plurality of brushes rotatably mounted about an axis parallel to said stationary brushing means, said rotatable brushes being adapted to cause a circulation of such liquid and articles t0 be cleaned, and 15 to coperate with said stationary brushing means to clean the articles in such liquid; and means mounted in the path of circulation and adapted to collect such articles.
