PRINTERS COLUMN-RULE.

Specification of Letters Patent.

Patented Jan. 5, 19115.

Application led April 1, 1914. Serial No. 828,893.

To all whom it may concern Be it known that we, WILLIAM LoviiLAND and HARRY ELLwooD SLoAN, citizens of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have jointly invented a cern tain new and useful Improved Printers ColumaRule, of which the following is a specification.

This invention relates to rules such as are used by printers in making up in a chase, columns of type or other matter. Such rules, as at present manufactured, are of one-piece construction provided with a short, thick Vshaped impression face and are generally unsatisfactory for the following reasons: Because of the great pressure exerted upon. the contents of a chase when an impression is being made upon a mat or matrix, either of the wet or dry variety, hardened steel rules are more lasting, but become corroded in use, due to moisture to which they are subjected. If non-corrosive rules, as for instance of brass, are used, the metal being relatively soft, the impression face of the rule is useless once the impression edge becomes worn. Possibly a greater objection resides in the fact that the faces of rules as at present manufactured, when used for impressions upon mats or matrices, either of the wet or dry variety, frequently fracture or otherwise mutilate or sever the fibrous material of the mats or matrices thus necessitating the making of a new mat for casting purposes. Further it frequently happens that when impressions are being made, the body portion of the rule is embedded in a mat, thereby ruining said mat.

The principal objects of the present invention are to overcome the above described disadvantageous features and provide, first, a printers column rule, which is practically eiiicient for the purposes intended and which embraces features, whereby hardened steel impression members may be interchangeably fitted to non-corrosive rule bodies. Second, to provide a printers column rule, the impression face of which is so designed that desired impressions may be vmade upon mats without fracturing the fibrous construction thereof. Third, to provide such a rule so constructed that the rule-body acts as a stop to prevent saine being embedded in a mat.

l/Vith these and other objects in view, the invention consists of the improvements hereinafter described and finally claimed.

The nature, characteristic features and scope of the invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof and in which:

Figure 1, is a view in side elevation of arule eXact size) embodying the invention. Fig. 2, is an end view thereof. Fig. 3, 1s a fragmentary view, partly in elevation and partly in section, drawn to an enlarged scale, of one end of the rule. Fig. a, is a view in cross-section, drawn to a much exaggerated scale and illustrating the parts in position for being assembled, and Fig. 5, is a similar view of the parts assembled.

Referring now to the drawings in detail 10, designates the rule-body which in practice is usually brass, due in part to its noncorrosive character and also for the reason that it may be easily worked to provide for the reception and holding in place of detachable impression faces to be presently described. One longitudinal edge of the body 10, is milled out throughout its length to provide a groovell, to which is fitted a continuous, very thin, hardened steel impression member 12. This member being very thin, the cross-section therof is very narrow and throughout the length of the member 12, and upon both sides thereof, from its impression edge to about midway its height, said member is slightly tapered as at 13, to further reduce its cross-section and provide the desired impression face. As clearly shown in assembling the rule, the tapered part of the member 12, extends slightly within the groove 11, of the body 10, so that this part of the member 12, is not closely hugged by the groove walls. To relatively interlock the parts together, the rule-body upon both sides thereof and throughout its length is slightly depressed, as at 14, by suitable means, so that the groove walls are caused to closely hug that tapered part of the member 12, contained therein, see Fig. 5. One end of the body l0, may be notched as at 16, immediately below and communicating with the groove 1l, so that a suitable implement may be inserted to pry loose a worn member 12, so

that a new one `be fitted to placelwAs before stated, brassbeing relatively soft, new members' l2, may be readily forced within the groove 11. very narrow, tapered cross-section of the member l2, the mats used to receive the desired impressions, readily accept such a member without having the fibrous mat texture fractured or otherwise mutilated as frequently occursby the use of the relativelybroad faced rulesnow' in general use. In' this connection, itis to'be further noted, that the dat' top of the rulebody, at the parts designated 15, forms shoulders which serve vto'act asstops to prevent the body cutting into'amat.' By being able to repla'cewworn' impression members with new ones,"the body portion `rof the rule may be used indefinitely, and since new impression members'rnay 'be' readily fitted to place at little Tcost,` a'gr'eat saving and'betterwork iii'printin'gis possible'by lthe above column rule.

lllhat we claim is J1; Aprintersjkcolumn rule embracing a body portion fhaving a squared top edge, whichf'top edge is longitudinallyf'grooved throughout the `'entire'length of said body portioiifand a thin gradually tapered impression strip removably fitted to said grooveftheworlr'end of said strip being projected 'x an appreciable distance beyond the squared top `edge of the rule, whereby atp'the juncture point of said squared edge and impression l strip shoulders forming stopsare provided. u

ZIA printers .column rule embracing a bodyI of. relatively soft metal said bodyhaving ajs'quared top edge, which top edge 'is longitudinally grooved throughout the eiitire length of.` said body portion, and a thin impression strip of relatively hard metal removably ftted to said groove the work end of said strip being projected an appreciable distance beyond the squared top edge of thei'l rule, whereby at the juncture point offsaidwsquared edge and impression' strip shoulderspforniing stops are provided.v

Ai printers column' rule embracing a bedr` perdn having e .Square ter, edge, which top ,edge is 'longitudinally grooved throughoutthe entire ylength of said body portion', and a thin'mgradually tapered impression strip Aremovably fittedI to said groove 1the 4vvorlfrend of said strip being P're'iee. edf'eln" eprleeeble' deenee beyond the "squared top edgepof the rule at least a p'eittiee'efjthe tapered, reife' ef Seid Strip beili'gcoiitained 'within said groove.

By reason of the" LMA printers column rule embracing a body portion of relatively soft metal the squared top edgeof which is longitudinally grooved to removably receive a thin slightly tapered impression strip of relatively hard metal the work end of which is projected an appreciable distance beyond the squared top edge of the rule at least a portion of the tapered part of said strip being contained within said groove.

5.

6.'.A pri'nters column rule embracing a rectangular body portion having squared bottom and top edges the top .edgebeing longitudinally grooved, to Iremovably receive a slightly tapered, impression strip of'a Vcross-section smaller than the body cross-section, of which a portion of said tapered strip is contained within said groove and of which a portion thereof projects beyondthe squared top edge of the body, whereby at the juncture pointI of said square edge and impression strip, shoulders or stops are`provi'ded. j I,

A printers column rule embracing a body portion having squared bottom and top edges the upper squared edge being longitudinally grooved throughout its entire lengthy and a thin slightly tapered impression strip removably and snugly fitting said groove with at least a portion ofI said tapered part contained within the groove and the remaining tapered part projected above the' upper squared edge the side walls of the body being longitudinally compressed adj acentl the body top to relatively interlockthe impression strip with respect to the body.

8."A printers column rule embracing a body portion having a squared longitudinally grooved top edge at least one'end of saidv body portion being notched immediately'bel'o'w and in communication with said groove and a thin impression strip removably iitted to said groove.

Intestimony whereof, we have hereunto signed our names.
