HARRY C. GAMMETER, 0F CLEVELAND, OHIO, ASSIGNOR TO THE AMERICAN MULTI- GRAPH COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO.

COLUMN-RULE.

Application filed July 21, 1913.

T 0 all whom it may concern:

Be it known that I, HARRY C. GAMMETER, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Column-Rules, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

My invention is particularly applicable to printing machines of the type known commercially as the Multigraph comprising a rotary printing cylinder having a series of under-cut channels in its perimeter extending parallel with its axis to receive complementary shaped flanged type which said cylinder presents in opposition to the other member of the printing couple. As ordinarily constructed, the only means with which such a machine is provided for printing lines at right angles to the lines of letter type consists of type fitting to the channels and having dash faces. Consequently, a series of such separate type must be used to print a line of greater extent than the dash carried by the face of a single type, and, unless said line type are accurately set and provided with means to hold them in alinement, they print a broken line instead of the continuous line desired.

Therefore, it is the object of my invention to provide such a machine with means to present a continuous printing face to print lines at right angles to the lines of words, and, as hereinafter described, such means includes a rule strip curved to fit circumferentially upon said printing cylinder and preferably having means fitting in said un dercut channels thereof adapted to retain it in set position.

My invention comprises the various novel features of construction and arrangement hereinafter more definitely specified.

In the drawings, Figure 1 is a perspective view of my column rule showing also a clip engaging its flange; Fig. 2 is a plan or development of a rotary railed printing member having type and my column rule 1nounted thereon; Fig. 3 is a cross section of a portion of such railed member showing my rule in side elevation; Fig. 4: is an enlarged cross section of the rule with a type on one side of it and a holding clip on the, other side.

As shown in the drawings, 10 indicates the Specification of Letters Patent.

Serial No. 780,159.

body of a suitably curved member carrying parallel rails 11 having grooves 12 in their opposite sides, leaving overhanging edges or ledges 13.

15 indicates type having grooves 16 in their opposite sides, whereby the type may be mounted in lines between the rails, the ledges of the rails entering the side grooves of the type.

The construction just described is the usual one in the Gammeter ll lultigraph.

The typeholding member may be a complete rotary drum or a segment, as desired.

My column rule consists of a curved strip adapted to seat on the face of the rails and extend transversely thereof and behold at right angles to the type lines to print vertical lines. The rule has an upstanding portion 20 and two lateral flanges 21, 21. For strength, the upstanding portion may be made wider than the mark desired to be printed, and the edge portion tapered to a narrow line, as indicated by the bevels 22. The rule is curved concentrically of the segment or drum, so that it seats snugly on the face of the rail. Its side flanges 21 may abut the lines of type, as shown in Figs. 2 and 4, or they may abut suitable clips or plugs held between the rails. Some of such clips are shown at 30. As there shown, they consist of channel-shaped spring members having outwardly bowed sides which are sprung in between the rails and extend beneath the overhanging ledge sufliciently to frictionally grasp the rails and hold themselves in place. To hold the rule on the rails against outward radial movement, the clips may be formed with lips 31 overhang ing the side flanges of the rule.

The type, together with the clips of some suitable form, hold the rule against shifting lengthwise of the type lines and against movement away from the rails. To prevent the rule shifting circumferentially about the drum or segment, I provide lugs projecting in from the ruled strip and adapted to e11- ter the space between adjacentrails. Such lugs are shown in the drawings at Qel. They are made by cutting through the flanges 21 and turning downwardly a portion of the flange adjacent to the cut. The cuts are made in pairs a distance apart substantially equal to the distance across the head of the rail, so that, when the lugs are turned down, they may engage opposite edges of the heads of a rail. The space 25 between the downturned lugs is left in the original curve of the flanges and rests on the top of the rail, the opposite'edges of which the adjacent lugs engage. There may be as many pairs of downturned lugs 24: on the rule strip as desired. That is, on a very short strip, one pair of lugs on each side flange engaging the head of a single rail, is sufficient. For longer strips, two or more pairs on each side are preferable. The engagement of occasional rails I have found amply sufficient to hold the rule.

It will be seen that my column rule may be very cheaply constructed and may be easily put in place on a drum or segment, either before or after the type has been installed therein. lVhen in place the rule may be held, either in conjunction with type or independently of the type. By mounting rules alone on the drum (holding them by the clips) I may print vertically ruled blanks, or I may print a ruled form with type between the lines. If desired, horizontal ruling may be accomplished at the same time by dash type, or line slugs occupying the type channels, as is well understood.

I do not desire to limit myself to the precise details of construction and arrangement above described, as it is obvious that different modifications may be made therein with out departing from the essential features thereof, as defined in the appended claims.

Having thus described my invention, what I claim is:

1. The combination, with grooved type and a holder therefor having overhanging rails, of a column rule adapted to be mounted on the face of such holder between type in lines, and tongues no wider than the distance between the rails and extending from the supporting edge of the strip and spaced to enter channels which the type lines occupy.

2. In a duplicating machine, the combination, with a rotary printing drum having a plurality of undercut channels in its periphery, of type having flanges fitted in said channels, and a rule strip having a printing surface curved in concentric relation with said drum held between said flanged type and having lugs extending into the intermediate portions of the channels but not into the undercut portions.

3. The combination of a drum-like typeholder having a plurality of parallel undercut channels in its periphery, type having flanges adapted to fit in said channels, and a rule strip having a printing surface curved in concentric relation with said drum and having inwardly projecting tongues which are no wider than the throat of the channels, whereby the rule may be inserted between typematter preexisting on the drum.

4. In a duplicating machine, the combination with a rotary printing drum having a plurality of undercut channels in its periphery, of type having flanges fitted in said n channels and a rule strip having a printing surface curved 1n concentric relation with said drum and having a radial dimension tongues which are no wider than the throat of the channels, whereby the rule may be inserted between type matter preexisting on the drum.

6. The combination of a drum-like type holder having a plurality of undercut channels in its periphery, grooved type adapted to fit in said channels and project beyond the surface of the drum, and a column ruling device adapted to be mounted on the face of the type holder between type thereon, said device consisting of a single integral piece formed with a central arcual portion rising from the drum to the same height as the type, flanges on the two sides of the arcual portion, and downwardly projecting lugs no wider than the throat between the drum channels, whereby the rule may be inserted between type matter preexisting on the drum.

7. A column rule comprising a printing strip having a lateral supporting flange and a lug formed of a downwardly turned cutout portion of said flange.

8. A column rule consisting of an arcual strip having lateral supporting flanges and lugs consisting of downturned cut-out portions of the flanges.

9. A column rule consisting of an arcual strip having laterally projecting side flanges, and integral lugs projecting downwardly from the side flanges.

10. A column rule consisting of a curved strip having an upstanding central portion, laterally projecting side flanges, and integral 7 lugs projecting downwardlyfrom the side flanges.

11. A column rule made of a single integral piece comprising a central strip, lateral flanges 011 opposite sides thereof, and lugs consisting of down-turned cut-out portions of said lateral flanges.

12. A combination, with a rotary printing member, of a concentrically curved col umn rule having a printing strip and lateral supporting flanges, and lugs comprising out out portions of the flanges turned downwardly.

13. The combination, with a rotary printing member having rails parallel with the axis, of grooved type held between said rails, and a column rule curved concentrically of the printing member and extending transversely of the type and having laterally projecting flanges resting on the face of the rails, said flanges being provided with lugs turned downwardly into spaces between adjacent rails, the lugs being arranged in pairs spaced apart a distance corresponding to the thickness of the rail head.

14. A column rule comprising a printing strip and laterally projecting flanges, and lugs formed by turning down cut-out portions of the flanges on opposite sides of the strip, said lugs being grouped in pairs on each flange.

15. A column rule comprising a printing strip and laterally projecting flanges, and lugs formed by turning down cut out portions of the flanges on opposite sides of the strip, said lugs being grouped in pairs on each flange, the lugs of each pair extending diagonally downward toward each other and having their ends a suflicient distance apart to engage the head of the typeholding rail.

In testimony whereof, I hereunto my signature in the presence of two witnesses.
