-To aZ whom it may concern:

Be it known that l, CHARLES E. MCNA luARA, a. citizen oi' the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented. certain new and useful Inun'ovcments in Marginlndicating Devices for 'lype-lVrit-ing Ma chines and I do hereby declare the following to he a full, clear, and exact-description of the-invention, such as will enable others skilled in the art to which itappertains to make and use the same.

i My invention relates to margin indicators for. tfvpewriting machines and has i or its object the provision of a convenient device for indicating the available writing space between the top and bottom of the page to be Written.

It consists of the constructions combinations and arrangements of parts hereinafter describecand claimed. I

In the drawings, Figure 1, is a front elevntion of one form of my said invention. Fig. 2, is an enlarged central vertical section of the same. l ig. 3, is a rear elevation ol the same. Fig. 4 is a perspective view' of it presser device forming part ol one l O llll of said invention. Fig. 5, is aside elevation of. said form 01 said invention showing parts of the carriage of a. typewriting machine upon which said invention is mounted. Fig. 6, is a plan View oia portion of the carriage of a form of typeu'riting machine coimnonly known the Remington, showing nipples upon which one form of my invention may be mounted. Fig. 7 is a perspective view ol a' modiiicd l'orm ol my said invention showing "parts ol' the carriage ol a ditl'crcntForm ol' typewriting machine, whcreoii the same is mounted. l 8, is a side elevation of onother modified i'orm of my said invention, showing the name plate of a third l'orm ol typewriting uuu'hine, whet-con the some is mounted.

in the drauings, l, is a body plate, which in one form of said invention is provided with oppositely extending arms 2, 2, having thimblcsB, formed on or attached to their outer ends which thimbles are preferably parallel with each other and directed at an angle to said plate. Formed on or attached to the rearward face of said plate, are stops 4 and i" spaced it suitable distance apart and formed on or secured to said rear face below the horizontal plane of the lower ends of said stops a foot 5. Said stops and foot are preferably formed by striking loacluxnrd portions of metal from the said body plate. Above said stiips is positioned. a pivoted plate 6 which pirotall coi'inoct'oi'l with said body plate, and is provided with suitable rearwardly turned side ribs or guides, as 6 and 6'; The pivotal connection botween said pivoted plate and said body plate is preferably eiicctod by forming an aperture A metal forwardfrom said pivoted plate to form lingers 7 which are adapted to extend through said aperture; said fingers are then clenched in said. body plate and stri lightly upon or over the forward face of said body plate The pivoted plate will t 111 be supported on the body plate by said lingers and said fingers will turn in said aperture. Positioned bet een said guides 6 and 6" and engaging the Lune is a scale bar 8 extending upward beyond said plat s, and adapted in operative position to rest at its lower end upon said foot Said s cale her is prcferably made of springmctal, or is resilient, and its lower end is preforahly'roundcd in Whole or in part, as at 8 so that when said scale bar is swung sideuise from erect to rccum bent'position, or vice versa, as it may be, as shown in blfllicll lines iii-Fig. l, together with said pivot plate, said lower end of the scale bar will clcarsaid foot. Said stops are sullicicnt to prevent the accidental turning or slipping of said scale bar and pivoted plate from operative position, but one or both of said stops are rcfcrablyshallow,- and when a moderate side pressure is applied to the upper cud ol the scale bar, the loiver end of said bar \iill spring or slip over said shallow stop 01' stops and the scale bar may be sr-guug down edgcwise to a horizontal position, as shown in broken lines in Fig. l, which latter position obviates the necessity of removing the dcvicc from the typewriting machine \rl'ioncvcr it 1s desired to cover the n'iachine with a close littiug hood as is commonly done engage said scale bar intermediate of its ends when it is in horizontal position and to prevent the accidental displacement of the some from such position by'gravity or vibration or very light strains. When said scale bar is in horizontal position it may he slid longitudinally between said guides so as to eX tend'equally at opposite sides of the center of said ivoted plate and so that it will not project eyond either end of the typewriting machine. The lower end of the scale bar is preferabl turned forwardly and upwardly upon itse f to form a shoulder as at 8 adapted in operation to bear against the lower edge of said pivoted plate and revent the accistops.

dental withdrawal of sai bar from said uides; but said shoulder may, if desired, be formed by striking forward a part of the metal from said scale bar in manner similar to the referred-method of formin said pon said scale bar is shdably mounted a stop 10 of any suitable form, provided with a set screw 10 whereb the same maybe fixed at any suitable pre etermined point on said scale bar. 1

In mounting this device upon that form of typewriting machine commonly known as the Remington thecarriage of which is provided w1th two vertically dis osed socket posts or nipples as 11 and 11 ig. 6,

the thlmbles 3, 3, are set down over said nipples, which will hold my said device u(pon said carriage, said scale bar then exten I in upwardly and rearwardly at an angle approximately as shown in said Fig. '5.

In order to mount said device upon that form of typewriting machine commonly known as an Oliver the carriage of which is provided'with two parallel frame bars as 12 and 12 I provide a base 13, Fig. 7, formthat form of ty ewriting machine commonly I roll on said name plate.

the arms 2, 2, and thimbles 3, 3, may, if desired, be omitted.

known as the Underwood the carriage of which is provided with a name late as 14, Fig. 8, having a rolled u per edge, my device is'further modified by omitting all of said base except the breast plate and by forming an S shaped roll upon the lower end of said breast plate adapted to engage the In this form also The scale marked on said scale rod is preferably determined by marking on the rod the length of the course followed by theisheet to be written from the type line, as X, of the platen roll as 15 (shown in diagram) to various pointson the scale rodwith reference to sheets of different lengths, allowance being made for a suitable margin. Thus for scaling a margin of one-half inch at the lower end of a thirteen inch sheet, 'the scale marl: 13 should be placed on the scale rod at a-disscale rod, said support clinc'd position.

tance of 12% inches from the t pe line of the roller following the course to he traveled by the sheet during the operation of writing. The operator knowing the length of the sheets used by him for various purposes adjust the stop 10 at the proper mark to allow for the desired margin at its foot. But other suitable methods of determining the scale may be used as will be readily understood, and within the scope of my claims, I do not therefore desire to restrict myself to the method described.

In using my device with said Remington machine, it is desirable to have a presser foot or roll to ress the paper, A, down above the laten roll and so prevent undue bulging or uckling of the sheet whichwould otherwise tend on some occasions todestroythe approximate accuracy of the scale with, rela-' tion to the length of the sheet to be written.- 81/ I have therefore provided the presser foot or roll 16 mounted on a reci rocatable arm 17,

in which arm is formed t e'slots 18. and 19,

through which extend the screws 20 and 21 by which said arm is secured. to an inverted U-shaped base 22. Said base is adapted to straddle and rest upon a block 23 mounted on a frame bar 24'of the carriage of said machine and carrying a paper guide B, the func- I tions of which part the arms 17 may er form. Said arm .17 is normally hel in yielding forward position by a suitable light sp g, as25 bearing against said arm and against said base.

My said invention may be further modified in details and minor particulars within the I scope of certain of my claims.

What I claim is.
