rllhe invention relates to pottery ware hav-i ing decorations thereon under the glaze coat, and more particularlyy to apparatus for transferring a printed'design onto the ware 5 before it isdipped into the glaze.

Pottery ware` which yhas been fired once, and 'before it has been glazed is commonly known as biscuit ware.y It yhas beenffound that a design printed onV tissue'v paper and thelile maybe transferred to biscuit ,ware4 by placing the paper with the printed sidel vdown upon the biscuit ware, and thencovering the paper with soft soap and rubbing over the same with a brush or a piece of flannel. f

However, it is necessary toi applya considerable force in the rubbing operation'iand a large amount of manual laboris involved, making the rubbing/operation a tiresome 29 and tedious process. f .f x' f Accordingly, it isy an object .of the present invention to Yprovide a simplefand `compactapparatus for economically applyinga rubhing or brushing action .to the back ofthe printed paper when it is placed in position on the biscuit ware, whereby the decorativer design will be properly. and uniformly trans-` ferred to the ware in a relatively short time.

` Another object is to provide improved 3G means for bringing the ware into operative' position relative to they rubbing element after the Vprinted paper is positionedupon the ware.

These and other objects `are attained byi Q5 the parts, combinationsv and improvementsVV which comprise the present invention, and which may be stated in general. termsas including a supporting frame', a drive shaft,`

means on the frame-forvrotating the drive shaft, a rubbing element on the drive shaft, a non-rotating table for supporting the ware and normally spaced from the rubbing element, and means for moving the table to n bring the ware into contact with the rubbing element.

A preferred embodiment of the present improvements is illustrated in the accompanyingdrawings, in which l Figure 1 is a front yelevational view of the improved apparatus showing a piece of 1931 semi No. massa;

- braced 'as shown at 13to maintain the frame rigid.`

Means' `for rotating the Vrubbingv element f parts Y may include amotor mounted on the upper end of the frame 11`b`and enclosed in a suitable housing 14; VAstarting switch 14ga is preferablyprovidedfor operating the mol tor.L

i The motor rotates the vertical shaft 15 journaled in t-he housing 14, and av rub'bin elenientvindicated generally at 16 is secured upon the'lower end of the. shaft 15.Y This rubbing element is preferably in the form of a `brush 17, having its bristles shaped to fitl the inner contour of the article to be decorated, asbest shown in Fig. 3. A

yMe'ans for supporting the ware prefer,-

ably includes a table 18 fixed upon the upper end of a vertical yshaft 19 below and axially aligned with the shaft 15. The upper surface-of the table 18 is preferably covered with friction material as indicated at 2O,v in order to prevent the ware from turning on the e abley when the brush 17 is in contact with the ware. i

The shaft 19 is mounted for vertical slid-` ing movement and against rotation upon theY lower portion ofthe frame 11. The means formountingthe shaft may include a supf porting bracket 21 secured to the'frame asV by bolts '22, and having -thespaced upper and lower shaft bearings 23 and 23 respectively, in axial alignment with the shaft y15, 'n The shaft19 maybeslidably keyed in these bea-rings vto permit `vertical sliding movement D *D 10o without rrotation .of the shaft.

Means for raising the table 18 t-o bring the ware thereon in contact with the brush 17, may include a pinion gear 24 rotatively mounted upon the supporting bracket 21, and

s adapted to mesh with the rack portion 25 on the inner side of the shaft 19.

The gear 24 is preferably fixed upon a spindle 26, which spindle is journaled in the bracket 21 and extends laterally outwardly lo therefrom. A lever arm 27 is secured at one end to the outer end of the spindle 26, and has a slot and pin connection at its other end with the manually operated lever 28, as indicated at 29. u The lever 28 preferably has its upper end *otally connected to the upper end portion of the bracket 21 as shown at 30.

A stop 31 may be secured to the shaft 19 to limit its downward morement by abutment of the stop with the bearing 23 when the table 18y is in the position shown in 3.

When it is desired to transfer a (lesion which is printed upon tissue paper and the like'to a piece of biscuit ware, the paper is 25. 4placed printed side downward upon the upper surface of the ware, in proper relative position to the contour of the ware. The parts of the improved apparatus areV normally the position shown in Fig. 3 due to 3g, the e'ect of rravity upon the table 20 and' ien the printed paper having shaft 19.

the desired. design thereon has beenproperly plied, to the ware as above set forth, thev baelrof the paper is covered with a soft soap 35, and the were 1s placed upon the table 20 in the central portion thereofthe table' occupying its normal position as shown in Fig. 3.

After. starting the motor to rotate the brush, the operator then exerts an inward' 4u. pressure on the lower end of the lever 28 moving theA same inward toward the frame 1I. This. inward movement of the leverz 28 rotates the lever arm 27 inwardly and also the gear 24. Rotation ot'v the gear 24 in a [3. clock-Wise direction as viewed in Figs. 2'and 3 carries the shaft 19 and table 20 upwardly untillthe ware. is in` contact with the brush 17, the bristles fitting into the contour of the Ware so as to exert a uniform pressure over 5o all arts of the printed paper;

hns it will be seen` that a simple and effective apparatus-is provided for exertingl a uniform in posltion on the ware for any desired length .15 of time, and the improved means for'raising vandA lowering the table provides for varying the pressure exerted as desired.

Obviously such an apparatus achieves a great saving in labor and expense, and it has 00. been found that a higher quality article is produced by the use of such apparatus than by the old manual methods.
