6 Claims.

Our invention relates to presses of the type shown in Reissue Patent No. 19,642, issued July 9, 1935, and more particularly to provide improved means to convey the wax carbon compound to an oversize form. That patent describes means to adapt a fiat bed printing press to wax carbon printing. On such presses the size ofv the form to be wax carboned is usually limited due to the construction of the press. Some 10 manufacturers of this type of press furnish auxe iliary ink distributor rolls which can be attached to the frame at a point in front of the impression cylinder. These auxiliary rollers receive ink from type or plates which are located sufficiently rearward to pass under the regular inking rollers and inturn distribute it to other type or plates located at the extremefront of the type bed. In

these attachments the contacting rollers are ro.

tated by the cohesion or tack of the printer's ink.

2 However, as explained in the said Reissue Fatcurrent to the heating elements contained in said roll.

3 Our means of accomplishing the foregoing objects may be more readily understood by having reference to the accompanying drawings, which are hereunto annexed and are a part of this specification, in which- 40 I Fig. 1 is a top plan view of a press equipped with our improvement;

Fig. 2 is a vertical sectional View taken in'frontof the attachment;

. Fig. 8 is an end view of the same;

Fig. 9 is a side view; and 55 Fig. 10 is a diagrammatic view showing the ent No. 19,642, issued July 9, 1935, melted wax rollers in their relation to each other and to the type bed.

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

As shown in the drawings the press is of the 5 type known as a Kelly press. This press has a reciprocating type bed I carried on rollers 2, only a portion of which are shown since the construction of the press constitutes no part of our invention. A rack 3 is carried by the type bed 2. 10

Our attachmentis mounted in multiple bearing plates 5 which are secured to the frame of the press by screws 6 or in any other desired manner. Only one of these plates is shown as they are duplicates except that they are right and left. I"he plates 5 provide bearings for the ends of the rollers forming the attachment, and also support a shaft 4 which connects the bearing plates.

Idler gears which are used to convey motion from the rack to the gears secured to the shafts of the various rollers, are mounted on stub shafts carried by one of the plates 5.

A form roller 1, preferably made of rubber secures the melted wax carbon from the ink plate located sufiiciently rearward to pass under the form roller 8 located near the center of the press which applies the wax carbon to the type or printing plate 9.

Obviously when the type bed is in the extreme rearward position with the front portion remaining under the impression cylinder, as is customary, the type or printing plate must not be located at a point beyond this inking form roller 8 or it will not receive any ink.

It will be clear from this description that if a printing plate 9 is located adjacent the front ll] of the type bed I that it would not be available for printing since it would not receive any ink. When the type bed passes to the rear the printing plate 9' passes under the inking form roller 8 which deposits the melted wax carbon thereon. As the type bed moves forward the plate is carried under the impression cylinder and the wax carbon spot is transferred to the sheet of paper (not shown). There is always a quantity of wax carbon remaining on the plate after it has made an impression. As a consequence, when this plate passes under the form'roller 1 it transfers to that roller whatever melted wax carbon remains on the plate. Inasmuch, however, as these plates 9 and 9' are located at different positions on the type bed in order to printspotsof wax carbon on the paper it is quite apparent that, regardless of the amount of wax carbon which might be deposited upon the form roller I in registry with the printing plate 9', it would not have any effect whatever as far as inking plate 9 is concerned. Moreover, by this time the wax carbon has hardened by reason of its being below the critical temperature at which it can be worked so that it could not be spread by the vibrator roller. I, therefore, provide means for heating the vibrator roller. This melts the wax carbon to a consistency at which it will fiow. The vibrator roller I I is contacted by a rider roller I2 which is preferably formed of rubber and this rider roller operates to spread the melted wax carbon picked up from the plate 9 by the form roller I over the surface of the vibrator roller, which, in turn, retransfers it to the form roller 1 so that the melted wax carbon will be on the roller 1 so that it will register with the plate 9 and thereby ink it so that when it passes underneath the impression roller and contacts the paper (not shown) it will transfer to the paper the wax carbon thereon.

In this way we make it possible to locate the printing plates at any point on the type-bed and yet deliver to them melted wax carbon at the critical temperature requisite to produce good work. The rollers are positively driven in the following manner. Idler gears I6 and H, the teeth of which mesh with each other, are mounted on stub shafts I8 and I9 which are secured in one of the bearing plates 5.

The teeth of the intermediate or lower idler I6 are in mesh with the teeth of a driven gear 20 which meshes with the teeth of the rack and converts the reciprocating motion of the rack to rotary motion which is transferred to the idlers I6 and IT. The teeth of idler I1 is in mesh with a driven gear 2I which is mounted on the shaft 2| of the vibrator roller II. The teeth of gear 2I mesh with gear 30 fixedly mounted on the shaft 3| of the rider roller I2.

This shaft 2 I extends beyond the bearing plate and carries a gear 22 which meshes with a gear 23 secured to the shaft 23 of the form roller 1 thus providing a positive drive for all of the rollers in the attachment.

Adjustment of the contact of the form roller I with the printing plate or plates is similar to that used on standard equipment, i. e., adjusting screws 25. The contact of the rider roller with the vibrator roller is adjusted by swinging the arms 26 on rod 4 and clamping it with set screws 28. Obviously these adjustments are duplicated at the other side of the press (not shown). The metal vibrator roller I I contains an electric heating element 29 one terminal 30 of which is attached to a collector 3| and the other to a collector ring 32. The rings are insulated from each other and are rigidly attached to the end of the vibrator roller II. The carbon brushes which contact the collector rings 3| and 32 are contained in a housing 34 mounted in a block 35 formed of insulating material which may be attached to the bearing plate 5 as shown in Figs. 7, 8 and 9 or in any desired manner.
