MACHINE FOR WRITING A PLURALITY OF SIGNATURES.

Application filed November 22, 1927. Serial No. 234,967.

The present invention relates to improvements in machines for simultaneously writing a plurality of original signatures,-the invention being particularly directed to the means for mounting the writing pens upon the pen bars of such machines. 7

The mounting of the fountain pens or other writing members upon the pen bars of a plural writing machine mustaflord an independent yield for each writing member so that all of the writing members will act uniformly irrespective of any slight irregularities in the surface of the checks or I other documents being inscribed, also there must be convenience for removing the pens from the pen bars for readily filling the pen barrels and such removability must provide for the return of the pens to their accurately adjusted operative position upon the pen bars, and finally it is very desirable to include in theinouniting for the master pen means for readily adjusting the degree of yield of that pen to suit the touch and style of writing of individual operators.

These desirable characteristics are included in the present invention in which each of the pens or Writing members has adjustably secured to it a clamping yoke formed with a transverse bearing socket designed to receive a bearing pin or trunnion projecting laterally from an angular bracket that is adjustably mounted upon the pen bar. This bracket upon the pen bar is formed with two laterally projecting integral lugs or shoulders between which the pen supporting pin or trunnion projects, and by which the pen clamp carrying the pen is limited in its rocking moticn upon the pin. or trunnion. One of these integral lugs or shoulders carries a small leaf spring which rests against the'rear faceof the pen clamp above .the

7 pin or trunnion andyieldingly holds the clamp in engagement with the other lug or shoulder, and yields more or less during the witing operation to ensure uniformity of action of the individual pens. This cushion: ing leaf spring serves, an additional function as a delicate spring latch for holding the. pen clamp in position upon the pin or trunnion, the ,face' of the clamp having a slight rib .or projection which rests normally in a groove or depression in the face ofthe spring for holding the clamp in position. This combined cushioning and latching spring enables an operator .to slip the clamp off of the journal pin or trunnion for the convenience of refilling of the pen, it being unnecessary to remove the clamp from the pen for this refilling operation whereby the pen may be quickly returned to operative position in its exact adjustment after it has been filled.

The pen mounting just described applies to all of the pens of a plural writing machine, whether the machine be a large machine of two'or more pen bars and a large number of Writing membersor the simpler form of machine in which there is only one pen bar mounted upon properly supported and poised pantographic arms. lnaddition to these features, the mounting for the master pen which is-especially observed and directed by the operator, ispreferably provided with an adjusting screw acting upon the cushioning and latching springto :take up more or less of the yield of the spring so that the operator can readily effect an adjustment to secure the degree of yield that he prefers. v

In order that the invention may be fully understood it will first be described with reference to the accompanying drawings and the patentable novelty more particularly pointed out in the annexed claims.

In said drawings:

Figure 1 is a plan view of a pantographicall mounted pen bar of a plural writing machine embodying the pen mountings of the present invention;

Figure 2 is a side elevation of the same;

Figuretl is an end elevation, partly in transverse section, of the same;

Figure 4 is a detail transverse sectional view of one of the improved pen mountings;

Figure 5 is a detail horizontal sectional view of the same Figure 6 is a detail perspective view of the master pen mounting showing the pen clamp separated from the supporting bracket of the penjbar.

The accompanying drawings illustrate the present invention as applied to a multiple writing machine of the type covered by Patent No. 1,080,347, dated December 2, 1913, but .I would have it understood atthe outset that this invention is not limited to this I specific type of machine, but is applicable to' other forms of multiple Writing machines in which a pen bar is mounted for universal horizontal movement above a writing bed or table; V

In the particular type Ol lflflCllllle 1llus= tratedjapenbar, 18 of T-shaped cross-section is" suitably huiig for universal horizontal movementon apa-ir or parallel links 20, the mounting of which willbe clear from thelde scription and illustration in the Patent No.

1,080,347, above referred to. :The parts of the mechanism common to thatshown in said n patent and not' specifically referred to herein are identified by the sarne.,i'eiei'ence numeral able brackets mounted upon the pen bar and pens or writing members and' detachably mounted upon saidbrackets with provision forproper, yielding action in operation and ready- 're'movabillty. r Each of the pen supporting used in said patent.

j The improved pcn mountings torshichthe present nvention relates comprises adjust relativel" movable oen clam 3s Carr in the brackets comprisesa body-portion"100 having a right angle flange-101 and 'atru'nnion .pin'102 which extends through'the bod'yportion 100 below and parallel with' the fiang'elOl formin asocket for the-reception of the horizontal web portion of the pen bar 18. The

flange T101 carries two. set screws 103 which engage the longitudinal slot 56 in the pen bar 18'and serve toclamp the bracket in the desired adjusted positionupon the pen bar. Byrelatively adjusting the: two screws 103 the-bracket 100' moving upon the pin 102 as a fulcrum can be caused to assumethe' de- 1 sired angular relation upon the pen bar in the same manner as the mounting bracket in the structure 'covered'by the above named patent; l

This bracketis formed upon' its outer I face with inte ral .lu 's or flan es 105 106 b D D 7 110 nearits upper free end.

Each pen 'or writing member has adjustably secure'dupon itsfb'arrel a pen clamp conslstmg of a'yoke and a strap 116 secured to the yoke by screws 117 and confining the barrel of the pen or writing member between them, I This-'yoke115 of the pen clamp I r is bored transversely at 118 to receivethe pin or trunnion- 102. of the bracket 100, the

inner face of yoke 115 being properly shaped tofit snugly'against the outer-face of bracket 100 between lugs orsho'uld'ers 105,106.- he

pen clamp yoke is slightly-thinner nan'the width of .the channel' l07 between flugs or flanges 105, 106, whereby the pen clamp can rock toa limited degree upon the pin or trunnion 102. A small dug or projection 120 on the rear face of the'pen clamp yoke 115 is 'designedto rest in-tlie groove or de pression 110 of;spring 108 to constitute a delicate latch for maintaining the pen clamp in its operative position upon the pin or trunnion 102. In this position the spring 108 tends to hold the pen clamp pr d Wamuy against the lug or flange 105 of bracket100, but yields in the writing opera- 7 tion under-pressure o't the-operator he pen moves over-slight inequalities in he surface of the documents being inscribe he" above described pen" mounting i common to all ofthe pensofthe plural writ ing machine. In additionto the described features, [the mounting for the master pen or that nearest the pilot handle bywhich the machine 1soperated, is preferably provided With an additlonal ad usting screw shown in detail of Figures '5 and 6 of the drawing, said screw. passing through the lug orflange 106- and engagingthe leaf spring 108 so that the yield of "this spring upon the pen mounting for the master pen can be regulated to a nicety to suit the'touch and manner of writing ofthe operator.

- In addition to the advantageous yielding mounting'for 'the pens Otwriting-members in a plural writing machine, the'improved pen mounting otlersmeans tor the readyremo'val of the pens from their mounting for the purpose of filling when thewritingpens are, as usual, 1'11 theform of fountain pens, The

pen clamps can be easily slipped 0E '01 their supporting-pins or trunnions and filledin a convement manner wlthout the removal of the pen clamps from. the pen barrels, and

afterward returned to their operative position without altering the, accurate adjustment of the parts. T he springs carried by the brackets upon. the pen bar serve the double function of yieldingly holding the pens to their 'work and affording a simple spring latch for preventing accidental displacement of the pen; clamps upon't-heir journal pins or trunnions; In the removal of the master penadjacent the pilot-handle it is desirable to loosen up the tension adjusting screw before attempting the removal oi: the pen.
