Thi invention relates tostencilling apparatus, especially of the. silk-screen type, and more Ph ticularly to apparatus intended for ornament ing articles having a frustoconical surface.

The invention is here shown applied t the ornamentation of tableware or dish s, Al hough these are relatively fiat, the. ornamental border usually has a frustoconical surface. Heretofpre, such tableware has been decorated e er by hand, which, however, is Very QXDtIiSiV .0 ha been decorated by decal transfer, which 3115915 expensive because of the considerable time needed to pply the necessary pi ces of d ca ransfe around the dish. A far .bfitter and faster Way to ornament a ceramic surface is by the use of a silk screen. suohscreens have he e of been used on fiat surfaces, and on cylindrical surfaces.

It has also been proposed in the literature to use a silk screen of frustoconical form, which is ro- .tated in rollin cont ct w th a otating dis u so far as I am awa is o o a h not proved successful,

The primary ob e of t e pres nt in nt on is to e a ly mp ove ap a a us f rnamenting articles such as dishes, having a frustoconioal surface. .A mo e p ticu r obi p is to pr vide a relatively simple and inexpensive form of ap paratus, in which the dish remains stationary and the screen remains stationary in contact with th is it in necess r on y to, m ve. a pi able squeegee over thesurface of the s een, 7 Fu t je sre to a i t e t er llv ttiiil and mov o t dish to be-orneme tedieiid t facilitate thecentering or registration of screen relative to the dish when first setting up the apparatus for us with a new screen.

over annular screen A. Thus rotation of the shaft for approximately 180 causes the two squeegees to travel over substantially the entire periphery of the screen.

Because of the cross-bar IS, the arrangement as so far described would not provide for full coverage. The arrangement would nevertheless be useful for interrupted designs, for the crossbar would be located between parts of the design. However, in accordance with a further and more detailed feature of the invention, the cross-bar l and the upright squeegee supports 28 and 22 may be so relatively shaped and located on opposite sides of the screen, that the squeegees may be revolved a full 180 despite the presence of the cross-bar. In the specific arrangement here shown, the radial portion 28 of the cross.

bar is bent downwardly or disposed at a lower elevation, while the opposite radial portion 30 of the cross-bar is disposed at a higher elevation. The squeegee support is bent or channeled at 32 to clear the lower portion 28 of the cross-bar, while the support 22 is bent or channeled in opposite direction at 34 to clear the higher portion of the cross-bar. The relation of the channel or bend 32 to the cross-bar 28 is best shown in Fig. 3, while the relation of the channel or bend 34 to the cross-bar 30, is best shown in Fig. 4.

In Fig. 3 the height of the higher portion 30 of the'cross-bar is shown in dotted lines at 30, and it will be observed that the bend or channel 32 clears the higher as well as the lower portions of the cross-bar. In Fig. 4, much the same remark applies to the dotted showing 28 of the lower portion ofthe cross-bar, for the bend or channel 34 of the squeegee holder 22 clears the part 28 as well as the part 30. On reflection, it will be seen that with this arrangement the shaft 26 may be turned a full 180, and in fact, a little more, thus causing the working edges 36 of the rubber squeegees38 to travel over the entire surface of the screen. The arrangement therefore may be used with a continuous design.

The dish 40 is properly located on base 13 by means of a locating disc or pilot 42. This is held on the base by means of a suitable screw 44. The pilot disc is. readily removable and replaceable when changing from the ornamentation of one size or type of dish to another. For each size of dish, a pilot disc is made up of suitable diameter to properly fit the dish.

The screen frame F is preferably circular on the inside, to conform to the circular dish, but the frame may be and preferably is square on the outside. This facilitates mounting and handling of the screen.

A different screen is provided for each type of dish. It is evident that the frame is designed to fit the dish, hence different frames are needed for dishes of different size. Moreover, dishes having the same size but different patterns, require a different screen or stencil, and it is preferred that the screen be mounted on the frame and left with the frame so'that it is available for use when wanted.

The squeegee holders 20 and 22 may be adjustably mounted on the cross-bar 24. In the present case the cross-bar is slotted at 46 so that the radius at which the squeegees are revolved 7 may be varied. The squeegee is secured to the cross-bar by means of screws 48. In this particular arrangement no provision is made for changing the angle of the squeegees because of the channels 32 and 34. However, in a simpler arrangement not required to rotate a full 180", the channels 32 and 34 may be omitted, and in such case the squeegee may be arranged for adjustment of angle, as is described later in connection with other species of the invention.

The spring C is housed within a hollow bearing 50. The top portion 52 acts as an upper bearing, while a removable plate acts as a lower hearing. The lower end of spring C rests on plate 54, while the upper end bears against a collar 56 secured to the shaft S. It will thus be evident that the spring tends normally to raise the shaft from the position shown in Fig. 1 to the position shown in Fig. 2. This in turn raises the squeegees and so provides clearance for elevation of the screen frame, as shown in Fig. 2.

The frame may be arranged to be raised bodily, but I prefer to hinge the same, as shown in Fig. 2, the hinge pin being indicated at 68. The base is provided with releasable lock means indicated at 62, and to release the screen, the lock means is moved from the dotted-line position 62 to the solid-line position 62, whereupon the screen may be raised from the broken-line position F to the solid-line position F.

The hinge means is preferably provided with appropriate screw adjustments for varying the position of the frame on the base or relative to the locating means, in order to properly register the ornamentation on the dish when first setting up a new screen. For this purpose, the hinge mechanism is preferably provided with a plurality of screw adjustments for varying the position of the frame in different directions. One arrangement for the purpose is shown in Figs. 9 through 12 of the drawings. In this arrangement the frame F (Fig. 10) has a plate 64 secured to it by means of screws, said plate including a track or guide 66. The hinge bearing 68 is formed on the lower end of a channeled member In which is vertically slidable on the guide 66. A wing screw 12 is threadedly received in the plate 64, and passes through a slot 14 in member 10. With this arrangement, it will be evident that the height of the frame or its distance away from the base, may be varied. Such a change is indicated in Fig. 10. by the spacing between the solid-line position 68 and the broken-line position 68 of the hinge.

It will be understood that there are two such hinge bearings 68 suitably spaced apart on the outer edge of the frame. These hinge bearings are received between mating hinge bearings 16, best shown in Fig. 9, the said bearings being formed on a plate 18 which may be moved axially of the hinge by means of screws having enlarged knurled heads 82. By turning one screw in a loosening direction and the other in a tightening direction, the plate 18 may be moved in one direction or the other.

The plate 18 may also be moved in a transverse direction by means of screws 84 received in mating threaded parts 86 of the plate 18. There are mating screws extending in opposite directions, so that one screw may be loosened while the other is, tightened, as previously described, but in this case the screws pass through plates 88 which are movable in the direction of the axis of the hinge along with the plate 18. At the same time the ends of the screws 80 are received in plates 90 which are moved transversely of the axis of the hinge along with the plate 18. Itwill be evident that altogether, adjustment in three mutually perpendicular directions has been provided.

A modification of the invention is shown in Figs. -5 and 6 of the drawing. In this arrangement, the yoke Y carries shaft S and handle I-I, just as previously described. The shaft is normally urged upwardly by spring C, and is provided at its upper end with a knob-92 which facilitates depressing the shaft from the position shown in Fig. 6 to the position shown in Fig.5, iustas was previously described. The shaft carries a cross-bar 94 with squeegees 96, and in this case the squeegees may be angularly adjusted, as :by means of the arcuate slots-98.

In the present case, one important change is in the stencil frame F, for the central portion 100 is not connected to the peripheral portion I102 by means of a cross-bar. Instead, it is-connected solely by means of the silk screen A.- However, .the central portion I00 is pressed firmly against the dish before the stencilling operation is be- -gun, this being accomplished by-a' presser 104 yieldably mounted at the lower end-of shaft S. The presser is normally urged downwardly-by means of a suitable compression spring I06, and the dimensioning of the parts is such that when the shaft is pushed downwardly by means of knob 9B, the presser bears against the central portion 100 of the screen before the squeegees reach the screen.

From a structural standpoint, the central portion of the screen might be omitted, and the .presser HM could be made of appropriate diameter to properly shape the screen before the stencilling operation begins. However, it is preferred to. provide the central portion 100 not only with a view to permitting the :presser -l 04to be universally applicable to a large numher of-differ- :ent screens, but even more important, to confine the heavy, ceramic paint, which is distributed on the screen, to the exposed annular portion. of the screen, instead of permitting-it-to run down to the middleof the screnwheredn no case could it be usefully employed The hinge mounting and releasable lock for the frame need not be described .in detaiL'sfor they may be identical with those described for use in connection withthe. first form-50f the/invention.

Still another form of the invention is. shown in Figs. 7 and 8. This .will have far lessapplioation than the modifications previously described, for in the present case the. arrangement is intended solely to ornamentthev flatcentralportion of the dish. However, the dish 'has a. frustoconical outer portion which would prevent the screen from being placed .flat over theidish. Instead, a frame F is provided which is frustoconically shaped on its lower, surface l'lll to .conform to the dish.v The screen is, stretchedacross the frame for use at the center of the -;dish,'and the squeegee [12 may be mounted diametrically on the shaft 1 M. It will be understood that there .is a handle and presser knob at the topsnf the shaft, although not shown in Fig. 7, and-gthat-a spring is located within the bearinglJBg-allas previously described. .1
