G. E.. MAXNER MEANS FOR SEASONIG PAPER Filed Dec. l, 1927 Patented Apr. 30, 1929.

MEANS FOB SEASONING PAPER.

Application `filed December My invention relates to that class ot' paper which is to be printed, where the sheets are ot' unseasoned stock, or of seasoned stock which has become aiiected by atmospheric conditions, and has for its object the provision ol mechanism which will deliver' dry heated air, under pressure, at any desired temperature, in between the sheets.

My invention may also be used, in connection with automatic paper-feeding ma chines, or the like, to blow heated dry air, of any desired temperature, in between the sheets ot' paper on a pile or load, thus breaking the static, and in this way facilitating the operation of the feeder mechanism in picking up a single sheet at a time, which it cannot do because of using cold green stock.

My invention has for its iurther object, to season the stock by blowing heated dry air, of the requisite temperature, above. and below the top sheets of the pile, thus eliminating wrinkles on the sheets when they are being printed.

Attempts have heretofore been made to overcome the diiiiculties caused by static, and by unseasoned stock, b directing blasts ot unheated air against tie pile of paper, or by directing steam against it. The steam is absolutely' impractical. The unheated air does not overcome the static, nor will it serve to season the green stock.

I have discovered that by locating an electrical heating element in the nozzle adjacent its oriice, the air can be heated and delivered intermediate the sheets of paper at any desired temperature, and that this temperature can be maintained with the required degree of uniformity.

My means of accomplishing the foregoing objects may be more readily understood by having reference to the accompanying drawings, which are hereunto annexed and made a part ot this specification, in which- Fig. l is a fragmentary portion of an automatic feeding device equipped with my improvement Fig. 2 is an enlarged sectional view through one of the nozzles; and

Fig. 3 is a diagrammatic View showing the means ot Varying the temperature of the air.

Similar reference numerals refer to similar parts throughout the entire description.

As shown `in the drawings, l indicates a pile of paper stock, which is to be fed to a 1, 1927. Serial N0. 236,974.

machine by the paper-feeding mechanism shown in Fig. l. Adjacent this mechanism (which I shall not describe further, as obviously it forms no. part of my inventionwhich may be used in connection with any of the well known paper-feeding mecha nisms,) I mount a nozzle S2, which may he curved (as shown in Fig. 1), having its orifice 3 adjacent the pile of papers 1, or it may be straight (as shown in dotted lines in Fig. 2), where that shape is more desirable for the location in which it is being placed. This nozzle 2 4is connected to a rubber tube 4, which leads to a suitable source or supply of air under pressure (not shown). Within the nozzle 2 I- mount a heating element 5, which is conveniently and detachably secured therein, a suitable insulation being interposed between the nozzle 2 and the heating element 5. Binding posts 'i' and 8 are mounted on the nozzle 2 connected to the element 5. The binding post 7 is connected to a rheostat 9, from which it receives electrical current through a wire 1l), which is connected to a source oi' electrical energy (not shown). The other binding post 8 is connected, by means of a wire ll, to the same source of electrical supply.

It will be apparent, to persons skilled in the art, that by moving the arm 1Q of the rheostat 9 to various poles, the amount of current passing through the heat-.ing element 5 will be varied, and consequently its telnperaturc will be varied. "The air coming through the hose it dry but cool, and strik` ing upon the heating element 5, is heated so that as it leaves the orilice 3 it is both dry and hot. I have shown a single nozzle, but it will be obvious that any desired number of nozzles may be used, in accordance with the pile of paper which is to be seasoned, to deliver the air continuously against the edge of the pile, adjacent the top sheets, with the result that there is constantly passing over and under the top sheets of the pile a continuous supply of air at a temperature suilicient to eliminate the static and to season the paper. In fact, the upper sheets float upon a cushion of dry heated air, thus very materially reducing the amount of-eifort required of the paper feeders, and insuring very much more effective action by them, as well as greatly facilitating the press work.

Having thus described my invention, what I regard as new, and desire to secure by 2.
