An apron, sometimes called a brushis a specification. ing apron, runs over spools or pulleys 5 My invention relates to mechanism for in the direction of. the arrow and passes cleaning and feeding tile or other similar obbelow the box at a distance about equal to jet-ts, and is especially intended to be used in the thickness of a tile.

The apron serves, as will parts may be used for cleaning tile only, later appear, to brush the surface of the tile, but since these two operations are usually and the character of the material may be essential in the art ot coating tile 1 generally varied to suit special requirements. In cases combine the parts and functions in one where the machine is used only to feed tile mechanism. the apron may be of any suitable material My feed and dusting machine is adapted with or without a pile surface. support A to supply tile to the receiving belt or apron 7 is in some cases placed below the brushing of automatic coating machine which carapron and under the box to support the ries tile to the coating device.

Below the line is a plan view of a section of the tile holder of feed the chains are free one pt where or box. they pass around idler sprockets 16 which 1 is a box, sometimes called a feed boX, may be employed if desired for taking up open at top and bottom, in which one or slack, and at their free points, as for in more stacks of tile are placed. It is usually stance at 17, the two chains may be pulled apart so as to free pins 12 from sockets 11 and so remove cross-bars 13 for purposes of readjustment. In order to adjust the crossbars a good many more sockets 11 may be provided on the chains than the number of bars usually employed requires so that various spacings of the bars may readily be obtained. The feed belt 8 is driven in the direction of the arrow (in the opposite direction to that of brushing apron at) by any suitable means.

Suppose the brushing apron at and feed belt 8 to be in motion and the parts to be in the position shown in Fig. 1. The stack of tile 3 rests upon apron 4: and since the apron is moving to the left as seen in the figure, the ends of the tile are urged against the left hand end of box 1. The cross-bar 13 just to the left of the box moves with the belt and encounters the left end of the lowest tile in the stack which is below and free from the box. The continued movement of the cross-bar carries the lower tile with it, against the direction of movement of apron at. The outer surface of the apron during this movement brushes the lower surface of the tile, effectively removing dust and dirt therefrom. As the lower tile moves to the right those above it in the stack also move in the same direction and approach the right hand end of box 1. lVhen the right hand ends of the tiles encounter the end of the box the upper tiles cease to move and the lower one is pulled from under the stack. After the left hand or rear end of the moving tile @L. As the rear end of the moving tile approaches the forward end of the box the other tile assume approximately the position shown in Fig. at. Vere apron 4 or other support provided for the tile stationary the tile would have a tendency to remain in the position shown in Fig. et; that is the lowest tile in the stack would in many cases not drop-clear of the box, and proper feeding would be difficult or impossible. By reason of apron a moving toward the left, however, as soon as the weight of the stack rests upon it the stack commences to move again toward the left so that it is carried away from the rear end of the box; the rear end of the moving tile shortly thereafter passes away from the box and the rear ends of the stack drop so that the tile in the stack resume horizontal positions with the lower surface of the lower tile flat upon apron 4:. Further movement of the apron carries the stack into contact with the front end of the box and the operation is repeated indefinitely, each cross-bar 13 carrying a tile before it.

It is to be understood that while only one stack of tile has been referred to, if several stacks are placed in the box the cross-bars will remove several tile at a time instead of one, and that the actions of the several stacks will be the same as that of the stack described.

The length of the box, as shown in Figs. 1 and 2, is somewhat exaggerated. The length of the box may be considerably varied in relation to the length of the tile, but in any event it should exceed the length of the tile sufficiently to permit the apron 4 to free the stack after the removal of each successive tile in the manner described.

Gross-bars 13 may be spaced apart longitudinally of belt 8 a sufficient distance so that after the removal of a tile and the stack has encountered the rear end of the box, apron at may move a considerable distance and by contact with the lower tile brush it considerably before the approaching crossbar engages the tile. By another arrangement only a slightly greater distance may be provided between the cross-bars than the length of the tile and the brushing efiect of the apron may be exercised upon the tile principally during the time the tile is being positively moved by the cross-bar against the direction of movement of the apron.

Various other modified adjustments or are rangements may be made, but it is not thought necessary to further describe them.

Adjacent to the forward spool 5, supporting apron 4, are mounted revolubly two pinch rolls 18 which conveniently have a covering of flexible or yielding material such for instance as soft rubber. These rolls are revolubly mounted and adjustable to accommodate different thicknesses of tile, and'they are driven by any suitable means in the direction shown by the arrows. They are set with their adjacent faces somewhat nearer together than the thickness of the tile which are to be fed, so that they squeeze the tile and positively carry it in the feeding direction. 19 are two other pinch rolls, similar to 18, placed somewhat to the rear thereof. Between the two sets of pinch rolls are two cylindrical brushes 20, one above and one below the line of feed. These brushes are revoluble and are mounted adjustably so that they may be moved up or down in relation to the feed line.

20 represents devices for adjusting the brushes and rolls.

The brushes are rotated by any suitable means in the direction of the arrows or against the direction of movement of the tile. To the rear of pinch rolls 19 a second or rear brushing apron 21 is carried on spools 22 and driven in the direction of the arrow or oppositely to the feeding direction by any suitable means. The'upper surface of apron 21 is in substantially the same plane as that of apron 4: and apron 21 may be of material as apron e or may vary in racteristics as has already been pointed in relation to the latter apron.

The forward portion of the machine. shown diagran'nnaticallv in Fig. 1 may be en'iployed without the rest of the mechanism and may be arranged to deliver the tile directly to the coating nachine when it is not necessary to brush the tile or the lower surface onl wnen y req tires brushing. A boat further description the pos sibility of using separate elements or combinations of elements of the invention with out cei otlnrs will be apparent to persons skilled in the art.
