WELDON Patented Oct. 14, 1952 REVOLVING MULTIPLE COLOR SCREEN PROCESS PRINTING TABLE Joseph T. Weldon, New York, N. Y., assignor, b'y mesne assignments, to Multiscreen Corporation, New York, N.

This invention relates to improved apparatus for the printing on fabrics, paper or similar material by means of the silkscreen process.

Such printing is accomplished by fixing the fabric to be printed upon on a suitable surface, lowering the silk screen thereon and then transferring the color thereto by means of a roller or squeegee. Where several colors are to be printed on the fabric, several silk screens are used successively.

One object of the invention is the provision of apparatus whereby in one operation of said squeegee the colors from a plurality of screens are transferred each to one of a like plurality of fabric pieces or the like so that, for example, if three colors are being used, three fabric pieces have all three colors printed thereon in three operations of the squeegee.

A further object of the invention is the provision of means for accurately locating the screens relative to thefabric pieces rately.

Still another object of the invention is to construct the device so that the fabric pieces are located on a plurality of platforms arranged in a circle and rotatable about a fixed base on which is hinged the screen means. I

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had tothe following description and accompanying drawings, and tothe appended claims in which the various novel features of the invention are more particularly set forth.

The apparatus for printing on fabrics}, according to the present invention, includes a circular bed plate l5 mounted on legs [6 and having centrally secured to its upper face a circular 2 Claims. (01. 1o1 115) stepped block IT. The block is secured in position by several spaced screws W see Figs. '7 and 8. Loosely journalled on the reduced portion of the stepped block El and resting on the step I8 thereof is a revolving table 20, said table also receiving support from a plurality of blocks I 2| fixed to the upper face of bed plate l5 adjacent its periphery (see also Figs. 3, 5, 7 and 8). The table is rotatably retained onthe step l8 and blocks 2| by a triangularly shapedmem'ber 22 fastened to the stepped block IT.

The triangular-1y shaped member 22 is com prised of a center arm 22 and a pair of converged side arms 22 and is secured to the stepped block I! by several screws 22 ,seeFigs. Sand '7. The triangularly shaped member 22 may be made of wood, metal or may bemolded of any desired synthetic resinous plastic material.

Fixed to the upper face of table 29 near the periphery thereofiand arrangedradially, are a large plurality of printing platforms 23 on which pieces of fabric 24 (Fig. 1) are secured-in any suitable way such as by gluing. Instead of separate platforms 23, there could be secured to the top face of the table 2E a single ring-shaped disc upon which the pieces of fabric 25 could be mounted. U

The mount for the printing means comprises a triangular block 25 (Figs. 1, 2 4 and 7) secured atop the bars 22. A bar 26 is longitudinally pivoted to oneedge ofbl'ock 25 byahinge 2'! (see also Fig.3) and has secured thereto by a second bar 28a printing framed?! comprising in the present instance longitudinal frame bars 3! and end bars 32. The frame 30 is divided into three sections by a pair of partition bars 33, and each section has secured therein. in the manner usual with such devices a silk screen 34. For clarity of description the three screens are differentiated by the latters a, b and c affixed tothe reference numeral 34. Normally the frame 36 is held in an upwardly inclined position, as shown in Fig.2, by a pair of springs 36 affixed to a block v and to the side bars 32. of the frame.

The block 35 is secured to the top face of the block 25 by several screws 35%, see .Fig- 7. The triangular block 25 issecured to the triangularly shaped member 22,,by screws 25*, see Figs. 2 and 4, which are threaded into complementary holes '2 5 formed in the converged outer arms 2 2'.of the triangular member 22, see Fig. 6. The construction is such that the frame 33 .is normallyin the position of Fig. l as just described, butcan be moved down over the platforms 23 by hand as shown in Figs. 2 and 4. The platforms 23, being. mounted on the table 29, are rotatable so that any'desi'red oneof the platformsfcanbe locatedunder the center section screen 34 of the printing frame, the adjacent platforms then being located under the screens 14 and 34. Thus, if a three-colored pattern is to be printed on the fabric pieces 24 secured on said platforms, each of the screens 34 may be provided with the desired pattern of one coloring agent. For example, each of the screens is pro-' vided with a ring 31 of a different color to provide a pattern of three differentily colored interwoven rings such as indicated at 38 (Fig. 1). The rings 31 are, of course, differently located on the screens 34 to take into account the varied positions thereof above the platforms 2'3. To-print pattern 38 the frame 30 is lowered, as described above, and an ordinary roller 40 (Fig. 10) rolled over each of the screens 34 to transfer the color to the fabric 24. The table 20 is then rotated to bring the platform previously under screen 34 under screen 34.", and that platform under 34* under 34, and so on until all of the patterns 38 are completed.

In order to simplify and expedite the operation of rolling the screens 34, a multiple roller 4| having annular recessed portions 42 to accommodate the partition bars 33 may be utilized to roll all three screens 34 at once.

In order to insure the correct positioning of the frame 30 above the several platforms 23, each of the latter has projecting from its outer edge a nail or pin 43 which, as the frame 30 is lowered, is engaged and cammed to the correct position (Fig. 4) by one or the other of the tapered sides of a notch 44 of inverted V-shape in the lower end of a bracket 45 secured to the frame bar 3| and depending therebelow (Figs. and 9).

It will be seen therefore that there has been provided a device for rapidly and accurately printing a varicolored design on a plurality of fabric pieces.

It is to be understood that a conventional individual squeegee may be used instead of the one illustrated in Fig. furthermore, frame 30 may consist of 3 separate silk screen members instead of the triple screen provided in this apparatus.

While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:
