Lsiclfi tl'lb Application filed July 10,

To all whom it may concern:

Be it known that l. Benn Animus, a 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 make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

lily invention relates to printing presses and an object of my improvement is to provide an improved process and apparatus for printing \vliere the impression of the type is taken through a ribbon.

l secure this object in the apparatus illus trated in the accompanying drawings in which:

Figure l is an elevation of a printing press embodying my invention.

Figure 2 is a plan view of the ribbon carrying frame detached from the press.

Figure is an elevation partly in section of the parts adjacent to the printing surfaces.

Figure 4: is a detail plan view partly in section on the line IVIV Fig. 1 to an enlarged scale looking in the direction. of the arrow.

Figure 5 is a plan view of the frisket. or sheet for preventing improper distribution of the ink, with the parts extended into the same plane.

Figure 6 is a perspective View of the )arts shown in Fig. 5 turned over upon itse f as it is used in the press.

a, is the movable platen-of the press upon which the paper to receive the impression is placed. 0 is the form-bearing part having the form or type c secured thereon. b is a frame carr in the inkin ribbon. Said in PD frame has an upper cross piece I) and a lower cross piece 6 and is pivoted in the manner of the frisket-bearing frame in the ordinary printing press. (2 d are rollers at the side of the frame upon which the inking ribbon (i is rolled, and is fed from one roller to another.

e is the frisket, this consists of two folds which are substantially duplicates of each other, a single one being of the usual construction. that is to say. having apertures therethrough opposite the printing type. One of these folds is on the side of the ribbon Specification of Letters Patent.

Patented Mar. 21, 1922. 1919. Serial in. 309,795.

adjacent to the paper and prevents the discoloring of the paper by the ink in the spaces between the type. The other fold is upon the other side of the ribbon and prevents ink being deposited on the ribbon bc-. tween the type as hereinafter described.

7' is an ink distributing disk of the usual construct-ion; and g g are the usual inking rollers. The ink is placed on the surface or table in the usual way and is carried by the rollers g g, to the face of the type 0 and is carried by the type to the adjacent side of the inking ribbon where the faces of the type come in contact with the ribbon, thus a portion of the ink from the ribbon is carried to the paper in the usual way and the ink removed from the side of the ribbon adjacent to the paper is supplied by the type to the opposite side of the ribbon so that the ink is never exhausted from the ribbon but is supplied at the same rate that it is used with the printing process, and is supplied directly opposite to where it is imparted to the paper. Thus the distribution of ink on he ribbon remains uniform and the impression on the paper is not heavier in one place than another. To prevent the imparting of the ink to the portion of the ribbon from which it is not being removed the fold of the frisket between the type and the ribbon is employed.

The frisket is folded over the cross bar 6 of the frame 7) at e and its lower edges c e are turned over the lower bar of said frame and secured as shown in Fig. 3.

In the construction. of the frisket I cut parallel slots adjacent and in line with one of the openings and turn up the material bet veen said slots to form a loop a: (Fig. 6) through which I insert a strip of the material of the paper g having barbs y turned up therefrom. This strip is inserted from below as shown in Fig. 6 and covers a slot more or less as may be required. a barb 1 engaging the edge of the loop 02 to hold the strip in place.

VVhat I claim is:

1. The combination in a printing press of a form-bearing and an impression surface, an inking ribbon between the form-bearing surface and impression surface, means for supplying ink to said'form, and a frisket between said form-bearing surface and said ribbon.

2. The combination in a printing press of a form-bearing-and an impression surface,

an inking ribbon between the form-bearing surface and impression surface, and means for supplying ink to said form, and a frisket bent over the upper edge oi" said ribbon and. having operative parts upon each side oi. the ribbon, substantially as and for the purpose described. 1 Y 3. The combination in a printing pressot a form-bearing and an impression surface, an inking ribbon between the "foriabearing surface and impression surface, means for supplying ink to saidform, a frisket between saidiorin-bearing surface and said ribbon and a 'Erisket between said ribbon. and said impression surface. 7 p.

4. A frisket provided witha loo-p a strip of sheet material extending through said ioop and adapted to cover one of the open ings in said frisket more or less according to the distance said strip is passed through said loop s i 5. A frisket provided with a loop, a strip of sheet material extending through said loop and adapted to cover one of the openings in said frishet more or less according to the distance said strip is passed through said loop, and barbs on said strip adapted to engage the surface of said loop for the purpose described.

6. A ifrisket provided with a loop a strip of sheet material extending through'said' being formed of turned up portions of said strip. 7

In testimony whereof, I sign this specification.
