Toailcchom it may concern.

Be 1t known that -I, EDMUND OCUMPAUGH, 2d, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Printing Devices, of which the following is a specification. I

This invention relates to a printing device,

designed for use as a check protector, the device belng arranged for printlng or em bosslng upon checks or other similar 1nstruments, words, figures, or marks, by which the said instruments or their values are limited. The object of the invention is to provide a printing device of the character, equipped with a type Wheel or drum, around the periphery of which is arranged several series of. raised type, and one end of said drum containing a circumferential index, comprising characters corresponding to said type.

A further object is to provide a combined platen and ink-roller support, which is oper able for alternately impressing the paper upon the type and re-inking the said type, the said ink-rollers arranged tocenter the type in advance of each impression, but beng free from contact with the type during printing operations.

A further object is to provide a novel and simple inking mechanism, which includes a plurality of revoluble inking pads preferably carrying. inks ofdifierent colors. And a further object is to provide means for preventing the blending of the colors by the ink of onepad mingling with that of an adja cent pad.

' The various features and parts of the in-.. vention will be understood from the detailed description which follows, and by reference Figure 1 is atop-plan viewof the device.

Fig. 2 is abottom-plan view of the same,

" with the cover removed. Fig. 3 is a vertical cross-section, substantially on line 33 of Fig. 7 is a similar view; snowing the said ing or'body having an open'bottom, which is closed by a detachable cap or cover 3, the latter being renrovable for access to the interior, as'shown by the dotted lines in Fig. 3. The top of said body has a longitudinal slot 4, which connects at one end' with a circular opening5. Rearwardly of the slot 4, two lugs 6 are preferably formed integrally on the top of the casing 2, and these lugs are provided with concentric perforations to receive a shaft or pintle 7, which supportscertain of the operating parts. The top of the casing 2 is, also provided with transverse slots 7 which are disposed adjacent. the lugs 6.

The type-carrier comprises a cylinder 8, having a central hub 9, the latter bored out to receive an arbor or shaft 10, the cylinder being made rigid on the arbor by a screw 11 which pierces one end of'the hub. The arbor containsan index consisting of figures or characters preferably starting with a unit, as 5, and "then increasing irregularly, as 5,

10, 16, 20, and so on, up to any suitable higher number, as 1000. The order'or arrangement of the index-characters istunim- ;portant and may be varied to suit the Work to be done by the machine. The flat ribs or rings 15,16 and 17 of" the cylinder 8 preferably conta'inflongitudinal rows of embossed printing type representin words and fig-' res, as for example,'$10$ OT OVER $10$, $50$ NOT OVER 33, $200$ NOT OVER $200$, and so on, as may be desired. In the preferred form of the device the lines of the type, as described, are placed directly oppo-x line with the corresponding num- 110 site or in bers or characters of the index 14, and the several lines of type are selectively brought into printing position, by the turning of the knob 12, until the desired index character, as 10 (see Fig. 1) appears in the center of the pening 5 directly opposite an arrow 17 The printing or impressing of the type upon the aper, such as a check or other instrument, which may be placed in proper position over the slot 4, is effected by a platen 19, which may consist of a compressible material, such as rubber or leather, or it may consist of a harder substance, such as wood or metal. The platen 19 is inserted in a groove 20 arranged longitudinally in a rib -2l, which dependsfrom a relatively broad arm 22, of a bell-crank or lever 23, the said lever having depending lugs 24, which are pierced b the rod or pintle 7, upon which the said lever is pivoted. 25 represents a coil-spring carried by the rod 7, which exerts its tension for holding the arm 22 of the bell-crank and also the platen 19 lifted above the type-wheel 8, (see full lines in Fig. 3).

To make the impression of the type upon the paper, the operator strikes the free end of the horizontal arm 22 of the bell-crank, a sharp blow with his hand, at the point indicated by the arrow 22. This depresses the said arm andforces the platen and paper against the face of the type-line which happens to be in the printing position indicated by the arrow 17, (see dotted-lines in Fig.

3). The impression of the typewill then appear on the paper, as shown in Fig. 9.

The inking of the type carried by the cylinder 8 is effected by a plurality of roller pads, as 27, 28 and 29, which may consist of any suitable ink-absorbing material, such as felt. The felts of the several inking rollers are mounted upon spools 30, each having a hollow center 30, and the said rolls are loosely journaled upon a shaft or rod 31, which is considerably smaller than the centers 30, so as to' allow the said rollers a certain amount of lateral play while in contact with the ribbed surface of the type cylinder. The ink rollers are positioned relatively to the cylinder 8 so that when said rollers liebetween any two adjacent lines of type, the line of type selected for the printing of the check will be centered with the arrow 17 which is the printing position. It is often desirable to use inks of different colors for printing each line of type on a check, such as red and black (see Fig. 8), and in order to prevent the said colors from blending, due to the close arrangement of the inking-rolls, I provide washers or guards 32 which are interposed concentrically between the ink rolls 27, 28 and 29. These washers have a greater diameter than the said rolls, and are disposed so that their peripheral edges lie in and follow the grooves 13. By this arrangement the ink of one roll cannot mingle with the ink of the adjacent roll, and the said washers also prevent the diiferent colors from flowing onto the adjacent type. The ink rollers are supported by similar depending arms 33 of the bell-crank, the lower ends of said arms being provided with slots 34, in which the ends of the rod 31 are journaled, and the said slots are preferably disposed at an angle which inclines rearwardly from the cylinder 8. By this arrangement of the slots 34 the ink-rollers may be readily placed in the working position either before or after the cylinder 8 is applied to the casing. Owing to the inclination of the slots 34 of the levers 33, the rearward movement of said levers breaks the contact between the rolls 27, 28 and 29 and the type cylinder 8 an instant before the platen completes the printing stroke. By this arrangement the type cylinder is free to move in either direction a sufficient distance to insure a fair and full contact between the platen and the face of the type. This is intended for correcting any slight discrepancy which might occur through the automatic centering effected by the inking-rolls, as described and it also prevents imperfect impressions which are noticeable in some of the former devices of the class, due to the fact that the centering mechanisms are in' constant engagement with the type cylinders, which tends to hold the said cylinders too rigidly during the printing operations, whether or not the face of the type and the impression surface of the platen are exactly parallel. When the arms 33 move away from the cylinder 8, as during the quick and sharp printing stroke of the platen, the inclination of the slots 34 prevents the inking-rolls from being accidently disconnected from the bell-crank. At each impression stroke of the platen, the lower ends of the arms 33 swing rearwardly, as from the full to the dotted line position shown in Fig. 3, and this movement being greater than the lateral movement allowed for inking rolls, the washers 32 strike against the back wall of the casing which forces the ends of the rod 31 forwardly in the slots 34, as shown in Figs. 3 and 7. By thus loosely journaling the inking-rolls in the slots of the lever 33, there is no strain upon the said levers during the printing operation, and the inking-rolls will therefor rotate freely for presenting new surfaces to the type after each printing stroke.

My improved printing device is extremely the inking mechanism eliminates several v parts formerly employed for doing the same work, and thereby lessens the danger of the working partsgetting' out of order.

Having thus described my invention, what I claim is new and desired to secure by Letters Patent, is

1. In a printing device, the combination with the casing, a revoluble printing cylinder journaled in said casing and having printing characters embossed upon its periphery, of a combined platen and ink-roll support comprising a rocking member pivoted above said cylinder and depressible by hand for bringing the platen into engagement with said characters and for moving said ink rolls away from saidcylinder, and a spring for raising said platen and for again bringing the ink rolls into engagement with the cylinder.

,2. In a printing device, the combination of the casing, a printing cylinder journaled therein having separate rings of printing characters thereon and rotatable in either direction, a bell-crank pivoted on said casing, a platen supported by the horizontal arm of said bell-crank centrally above said cylinder, a plurality of inking rolls carried by the depending arm of said bell-crank, said bell-crank rockable in opposite directions for alternately moving said platen and said ink rollers toward and from said printing cylinder.

3. In a printing device, the combination with the casing, a type cylinder journaled in the casing having circumferential rings of embossed type, a platen, and an ink-roller for each of said rings of type,'of a bellcrank pivoted above said casing, one arm of said bell-crank supporting said platen directly over the center of said cylinder, the

- other arm of said bell-crank supporting said ink-rolls below said cylinder adapted when rocked in opposite directions to alternately move said platen and said ink rolls toward and from said type.

4. In a printing device, the combination with the casing, a printing cylinder journaled in said casing rotatable in either direction and having type'characters thereon, a platen movable vertically toward and from said cylinder, and inking-rolls movable laterally toward and from said cylinder, of a bell-crank pivoted above said cylinder, one arm of said bell-crank supporting said platen the other arm of said bell-crank supporting said ink-rolls adapted when rocked in opposite directions toalternately move said platen and said ink-rolls toward and from said cylinder.

Gopies ofthis patent may be obtained for disengage the ink-rolls from said rings, and

means for automatically rocking said bellcrank in the opposite direction for moving said rolls toward said rings and for simultaneously lifting said platen away from said rings.

6. In a printing device the combination of the casing, a printing cylinder journaled therein having separate rings of printing characters thereon and rotatable in either direction, a bell-crank pivoted above said cylinder, a platen carried by one arm of said bell-crank, a plurality of independently rotatable inking-rolls carried by the other arm of said bell-crank, means for resiliently holding said platen above and free from said cylinder, said bell-crank rockable in opposite directions for alternately moving said platen and said ink rollers toward and from said printing characters, and means interposed between the said rings of printing characters for preventing the ink deposited on one ring of printing characters from mingling and blending with the ink deposited on the adjacent rings of printing characters.

7 In a printing device the combination with the casing, a revoluble cylinder journaled therein and having lines of printing characters thereon, a platen disposed above said cylinder, and a revoluble inking mechanism, of a common support for the platen and said inking mechanism, comprising a bell-crank operable by hand for depressing said platen toward one of said characters and at the same time moving said inking mechanism away from a difierent line of said characters, and a spring for actuating said bell-crank for freeing said platen from the said characters and at the same time moving said inking mechanism into position to contact with all of the characters when said cylinder is rotated.

In testimony whereof I afiix my signature in presence of two witnesses.
