Specification of Letters Patent.

Patented Sept. 27, 1921.

Application filed February 13,1920. Serial No. 358,444.,

To all whom it may concern:

Be it known that I, REED ADAMS, citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Printing-Presses, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to makeand use the same, reference being had to the accompanying drawings, which form a part of this specification.

y invention relates to printing presses. In the accompanying drawings,-

Figure 1 is a side elevation, partly in section, of an apparatus embodying my invention and so much of a printing press as is necessary to indicate its connection therewith.

. Fig. frame.

Fig. 3 is an end in Fig. 2.

Fig. 4 is a detail elevation of the ribbon and frisket-bearing frame.

a is a platen upon which the sheet of paper is placed to receive the impression. This has a surface a at one level and a second surface a at a greater distance from the surface of the platen, that is to say, the surface is extended outward by padding or suitable means, for the purpose hereinafter described.

f is the inking table and g, g are the inking rolls. Upon each side of the frame 0 extending parallel to the sides thereof is a track f upon which run guide rollers at the ends of the rollers g, g to constrain the motion of the rollers g, 9, so that their inking surface shall be held at a definite distance from the surface of the frame 0.

Z: represents a body, or form of setup type, the surface of which comes to the conventional level above the plane of the edges of the frame 0. j is a block having its surface extendingv to a level at a less distance from the plane of the edges of the frame 0 than does the outer surface of the type 70. Upon the surface of the block j an address plate is placed and removed and another plate inserted after each impression. The object is to make a number of impressions having a part of the printed matter in common and the rest changed at each impression and to use different inks or colors at each impression. To this end, I print from a type form in the usual manner in conjunction 2 is a perspective view of the type view of the parts shown and plate thereon.

with a movable pre-inked ribbon at' the same impression.

b is an inking ribbon which is carried b a frame and travels in front of the block 7' c is a fri'sket carried by the same frame as the ribbon b and hav- 111g openings 6 c (Fig. 4) throughwhich the impression of the type body 70 and the address plate j on the block is taken. The part a of the platen a which corresponds to and forms an impression surface for, the address plate is slightly raised above the rest of the surface of the platen, as shown in Fig. 1. The surface a of the platen ais that upon which the ordinary set type makes its im pression, and the part a is raised up a distance corresponding to the difference of the height of the set type 70 and the printing surface of the impression plate on the block 7'.

The sheet upon which the impression is to be made is placed over the surfaces a a and the platen is brought up against the type in the frame 0 in the usual way to cause the impression to be made. The printing is made by the address plate through the inking ribbon b. The type 70 make their impression in the usual way;

After each impression, the inking rollers g, g are moved up to the table f to obtain a supply of ink and then moved down the tracks 7, holding them always above the address plate on the block j, but permitting them to contact the type in the form is.

In addition to the operation of the device indicated distinctly in the above description, there is the additional advantage of being able to use different colored inks as the ribbon may be changed, or the ink applied to the fixed type may be changed.

What I claim is:

1 In a printing press having inking rollers, a body of type having its printing surface so located as' to receive ink fromsaid rollers, an address-plate supporting surface located out of the path of travel of said rollers, means for supporting an inking ribbon in front of said address plate holding surface and a platen adapted to receive an impression'sheet and press the same against the printing surface of said type and an address plate on said surface.

2. In a printing press having, inking rollers, a body of type having its printing surface so located as to recelve ink from said rollers, an address-plate supporting surface located out of the path of travel of said rollers, means for supporting an inking ribbon in front of said address plate holding surface and a platen adapted to receive an impression sheet and press the printing surface of said type and an address plate on said surface, the surface of said platen being adjusted to different,

heights to correspond to the difference in level of the printing surfaces of said type 10 and said address plate.

the same against 7 REED ADAMS.
