The carrier is: nret'crabl charac pression zone 2 may be brought against the the carrier. After the coated/object 3 leaves the impression zone 2 the surface flow of coating on the carrier 1 sinksinto the body thereof, due to itsrelease from or passage beyond the bearing 8, or to the tendency to create a vacuum between the carrier and the supporting abutment 6 as they separate. The incoming conveyer is an endless belt 4 carried upon rolls. The outgoingconveyer 5 is similar in construction to conveyer 4, but the whole conveyer-5 is adjustable longitudi nally whereby its receiving end may be set at varied distances from the carrier 1. This adjustability permits the object coated (depending upon its length) to strike such an angle with respect to the carrier that no excess or ridge of coating is left upon the rear of the object as it leaves the carrier, a condition likely to result unless special provision is made to prevent the same. An elastic guiding or feeding roll 7 is adjustable vertically for difierent sized objects 3, and may, if desired, effect some degree of compression, as theypass through the impression zone.

Fig. l is a cross-section and diagrammatic view of a machine embodying the im-v proved process. Figs. 2 and 3 are similar views of modified forms of the coating means. Fig. 4: is a side view partly broken away of a form of the coating carrier, and Fig. 5. is a similar view,of another form thereof with the carrier support removed. Fig. 6 is a cross section of another form of carrier.

An agitator 10 is provided in the tank of coating, below the drum, of any desired construction. It is mounted at 16' on a vibrating frame 17 and may constantly agitate the coating 15 between the underside of the'transmitting means 11 and bottom of the supply 9. Yielding means between the ositive drive and the agitator, such as a rive cam 18 and spring-supported roll contacts 19 prevent any tendency of the connections breaking if the coating mass at the bottom of the tank should dry or solidify. In the .latter case the agitator loosens upthe material and itself gradually. 20 is a feed roll assisting in carrying the coated objects away on the conveyer 5. It must not be understood however that these specific features alone may'carry out the process. The carrier 1 may be an endless belt, for example, or it may fit the abutment 6 closely. The incoming and outgoing conveyers 4 and 5 may be of any known form. The abutment 6 may be stationary and of various shapes. The.

contacting means 8 may consist of rolls bearing on the interior surface of the carrier, by means of which the carrier may be brought into contact with the supporting.

abutment in advance of the impression zone, or other means employed to shift the same. Thedammay be a stationary ocket instead of rotary, The coating may e supplied to roll 7, hung in bearings oscillating about the impression zone, may swing to the position :-shown in dotted lines and carry the coated,

object 3 into substantially the position shown.

here the outgoing conveyer is adjustable to and from the coating carrier the. loose character of the coating surface is not essential, nor where the conveyer is inclined.

In fact several independent means of effecting the control of the uniform application of the coating to the object as the latter leaves the carrier are contemplated; as, for example, (1) adjusting the foraminous surface upon the support; (2) inclining the outgoing conveyer to the line of travel of the object coated; adjusting the outgoing conveyer bodily to and from the carrier to vary the distance between them; and (4) oscillatin the compression roll above the surface of the coating carrier.

22 are means for adjusting conveyer 5. Instead of the feed-drum the source of coating supply may be a pipe leading. the coating solution to and upon the carrier, or under the carrier, and a ainst it preferably in the neighborhood of t 1e impression zone, so that the coating will be carried forward thereto. A feature of this inner or under supply to the carrier serves to effect both the screening and the supply of the coating to the carrier. By this latter plan ill-digested coating which ordinarily would be carried up on the outside method of supply and deposited upon the surface of'the ob-.

ject coated, is prevented entirely by thisinner method of screening supply.

Other coating-supply means are shown in Figs. 2 and 3. In Fig. 2 the coating is pumped through a tube 23 having lips 24,

between which the coating is caused to. flow (by'a pump, fountain, or the like) to the carrier. and carrier support. In Fig. 3 the carrier or carrier-support itself is made a conductor of the coating. The coating flows out through the perforated shell 25 to the carrier, which may be composed of elastic cellular material 26 thereon, and an outer foraminous sleeve 27. But the articular construction of the-carrier may e varied within wid'e limits. In anexterior supply system the carrier may.be imperforate and rigid pervious or elastic. In an interior supply system the carrier is preferably perforate, and rigid or elastic.

In any of the forms in Figs. 1, 2 and 3 the carrier ma assume the formcf a sleeve 1,f or a pluraity of sleeves, (1 and'28 Fig. 3)

kinds of articles by mach incs.

mountab e difficulties. cur mainly in connection 55 or a belt, (29 Figs; 2 and 3) or a sleeve and belt (1 and 29 Figs. 2 and In the shell or sleeve form of carrier, the inner surface may be perforated metal 30 (Fig. 4) or woven metal 31 (Fig. 5). The surrounding layer may be elastic fiber 32 or elastic composition 3-}, such as rubber. 'Good results are secured by cross-ribbingthe fabric 33; those in the form 33 shown '(lincl-ined) giving better results than where he ribs are axially and diametrically disosed. Excellent results are also obtained y making a. composition fabric 36 (Fig. (5) with a series of cells or pockets 34 ilreely open on the inner side 36 and having a series of relatively smaller perforations 35. As this style of carrier, Whether ofthe belt. or sleeve for i is :brought in contact with the carrier-support, a graduated supply of coating is pumped out of it, by regulated compression, sufficient to evenly coat the object. In the sleeve form I may employ flanged collars 37 on either end of the sleeve against which may bear the rolls 8. The flanges prevent the lateral spread of the coating and the collars serve to transmit the rolling adjustment of the sleeve.

, Other means of efl'ecting the adjustment of the carrier with respect to its support may be employed. One or more rolls for example may be arranged to bear on the inner periphery of the sleeve 1, or the axis of the sleeve may be made to shift in any way. In fact many known means may be employed for pertorn'iing all these functions, allof which are contemplated in the improved process. over the objects instead of the ol'ijects being :fed to the apparatus. The coatingcarrier its support, the agitator, drum. convcym's, may all be driven from one source of powerby any suitable known means.

The coating carrier 1, in the particular form selected for illustration, shows an in her perforated shell, a cellular elastic covering over the shell, and a previous or foraminons exterior layer pretcrably of "metal. fl t is a very dillicult matter to coat some 'lilcs, iorinstance, have been covered for glazing purposes entirely bylhand comn'iercially, owing to the resence of these hitherto in ur- These diliicultics ocwith white tile, the coating upon which, where a machine is .used, having a tendency to form a. head or ridge upon one edge of the tile.
