7 all 710m it may concern:

Be it known that 1', JO N CURTIS BLUE,

a citizen of the United'States,andresident of Brookl n, in. thecounty of Kings and State of ew York,have invented certaln new and useful-Printing lviachines, of which the following is a specification.

This invention relates to printing mach nes using "movable types and my improveinent is directed particularly to types tor ruling l nes in connection wlth the multigraph machine, in WlllCl] longltudlnal channels upon the se mental drum receive the character types and the line producing types lie circumferentially upon the drum or transversely across said longitudinal channels. V

Hitherto dii'ficulty has been experienced in looking these-line rules in their set posi tions, which may besuch as for the production by said rules of lines separating col umns of type matterfor margins, and for other purposes, because the anchorage they receive is. provided by the abutment thereon or" character types under the locking engagement of spring clips, or by the direct abutment thereon of the clips. Under these forms of engagement the linerules are insecurely held, and are apt to either fall out of place in the operation of the machine,

or to become distorted from their true linear direction.

Therefore my invention consists in the provision of more secure anchorage means, wherein the line rule is accorded a. substantial base portion that it may have firm seating upon the rail surfaces, and also. wherein lateral lugs, extending from one or both sides of said base portion, further enlarge the seating capacity of said rule. Furthermore these lateral lugs are distanced apart sufficiently to provide between adja-' cent lugs recesses adapted to receive the mount portions of character type, or slugs if character types are not'employed; or else the clips themselves may fit within these recesses, in order that in any one of these instances, frictional abutment of the adjacent member against the side of the line rule, and its engagement within the recess provided by a pair of lugs, may firmly lock the line rule in its desired operative position.

In the drawing:

Figure l is a plan view of a drum segment, forming part of a multigraph machine.

Application filed me e, 1220. us in. 386,398.

My 'ii npr oved line printing type or D ieg or printing height,

shamans tettersratsnt. Patented Oct-1 i Fig. 2is an end view thereof, partly in section. V

Fig. 8 isa partial plan View, enlarged;

Fig. 4c is a sectionxonthe line 4.-4 of Fig. 3, and y "Fig. 5 is an enlarged cross-section of a line rule; v

In said iigures let 1 indicate the typeholding segment of a drumsuch as comprising part of a multigraph machine, fsaid segment having the spaced, parallel rails Qfex tending longitudinally thereof, with theunder-cut channels 3 for engaging the base portions t of typesfi, or of slugs 5 and for similarly cnga ingihe shanks 6 of spring v I O I clips fr, these elements and members be ng of the usual known character.

consists of strip of suitable material, curved lengthwise to 'conl'orm to the cirrule cumierential contour of the drum segment,

over its rail surfaces, to seat thereon, and being or any desired length, said strip be and having a relatively thin, outwardly tapered upper portion 8, for iine printing, and a relatively "thick lowerportion 9, with a Hat base 10, whereby said strip may be firmly seated upon and across rails 2L Also, extending laterally from one or both sides of said portion 9 are a number of lugs 11, said lugs occurring'at such spaced intervals apart as to each lie centrally over a rail 2. This does not mean that the lugs 11, at each side of a stri must necessarily equal the number of rails spanned by the rule strip, but preferahly each pair 0:"? lugs should lie over adjacent ra-ils. The lug bases are flush with the strip base 10, because it is-a function of the lugs that they should augment the firm seating characteristicoi the strip upon the rail surfaces, to maintain the upright position of the strip thereon.

Also each pair of lugs 11, lying upon adjacent rails, present between them a recess for the reception of type or a slug, which may thus be frictionally engaged between said pair of lugs andalso abut against the inclosed side portion of the line printstrip; the types or slugs, or both, being in abutting relation with the'line printing strip, in a recess between lugs 11, to thus provide the desired anchorage without the use of character types or slugs.

When it is desired to produce horizontal lines with my line ruling device, as for under-scoringand other purposes, the line rule may be anchored in place upon a rail by causing either types, slugs, or clips, held 1n adjacent rall grooves, to abut against the line rule at either side thereof.

I claim v V 1. A sectional printing rule for, typeholding, rail surfaced drums, said rule having an upper printing surface, a seating base to lie upon the upper surface of a drum rail, and a series of thin vertical lugs,'whose bases are solely in the plane of the rule seating base, andarranged to lie each upon a rail surface within its span, to assist in.

maintaining the rule perpendicular to the drum surface.

' 2. A segmental printing rule for typeholding, railsurfaced drums, said rule having an upper printing surface, a seating base, and laterally extending lugs, adjacent lugs providing a recess for the lodgment of a lock member in abutting relation with said rule.

3. A segmental printing rule for typeholding, rail-surfaced drums,1said rule having an upper pr'inting surface, a seating base, and laterally extending lugs to co-act ith the drum rails as seating elements, ad jacent lugs providing a recess for the lodgment of a lock member in abutting relation with said rule.

4:. in a multigraph machine, having a drum segment with spaced parallel rails and means for adjustably .e 'igagi'ng character types, in combination, a line printing rule in segmental form, said rule ha'vlng'a substantial base portion wl'iereby'it may lie upon I type or slug, to be locked therein in abutting relation w t said rule. w it igned at the borough off l'anhattan, in the city, county, and State of New York, this 1st dayof June, A. D. 1920.
