UNITED S P NT 'F ICEf-L JOS PH P. BELAND, or QUEBEC, "QUEBEC, CANADA.

I v norromnnn ror rAG MAnerNEnf To all whom it may concern:

Be it known that I, JOSEPH P. BELAND, subject of the King of England, resident-of Quebec city, in the Province of Quebec and Dominion of Canada, have invented new and useful Improvements in Bottom and Top Page Marginers, of which the following is a specification.

The object of the invention is to provide an apparatus in the form of an attachment applicable to various standard and other types of typewriting machines for determining top and bottom margins of pages with accuracy to facilitate the securing of uniformity in the operation of the machine in continuous or plural page work without involving the necessity of experiment or loss of time incident to closely watching the progress of the work.

Further objects and advantages will appear later it being understood that changes in form, proportion and details may be resorted to particularly in adapting the attachment to various kinds of machines,without departing from the spirit of the invention.

In the drawings:

Figure 1 is a plan View of the device applied in the operative position to. a typewriting machine.

Fig. 2 is a side view of the same.

Fig. 3 is a section on the line 3-3 of Fig. 1.

Fig. 4 is a plan view of the endless gage element.

In the construction illustrated a continuous or endless gage element 10 is employed to traverse a guide roll 11 mounted upon the spindle 12 of the platen 13 of the typewriting machine and an idle or guide roll 14: supported by a suitable bracket 15 and of a sufiicient diameter to support the gage member, consisting in this instance of a tape, at a proper degree of tautness. The gage member is graduated to-represent space between lines of writing of the typewriting machine and numbered consecutively as for example from 1 to 95 for a standard legal size sheet having a length of 13% inches. Obviously the length of the gage member and the number of graduations may be varied to suit the length of the page or the character of the work or the spacing of the machine, or if, with a standard gage adapted for the 13% inchpage in use, a sheet of less Specification Que rsmm.

length may be -employed, as for example of I the letter size, simply by determining the length of said sheet by any suitable measure,.and utilizing only that portion of thegage which is represented by such length. The guide roll 14 is loose for movementin either direction to correspond with the movement of the operating roll 11 which while loosely mounted upon the spindle of the platen to permit of adjustment to bring the proper graduation thereof in registration with the top edge of a sheet inserted in the typewriting machine, is adapted to be turned with the platen during the feeding movement thereof as the writing progresses from line to line. To this end any suitable means of connection may be employed such as a pawl and ratchet 16 and 17 so that while the r0ll'11 will receive motion from the platen during the feeding movement of the latter, the said roll is capable of an independent movement to secure the proper initial adjustment thereof. r

The pawl 16 being carried'by the guide roll 11' and the ratchet wheel being carried by the platen spindle, motion is communicated to the guide roll by the spindle and the ratchet teeth are so disposed thatendless motion will be communicated when the platen roll is fed forwardly, as in writing.

In operation, assuming that a standard 13*} inch page is being employed, it should be determined at what graduation of the gage member the first line of the writing shall appear, as for example, the tenth space, to thus determine the amount of the top margin. The writing may then progress in the ordinary way without attention on s the part of the operator until it has reached a point near the bottomof the page which may be determined upon to leave the proper bottom,margin. As the graduation. of the gage member reads backwardly the number of line spaces remaining on the sheet at any point in the progress of the writing writing on each successive sheet in accord- 110 will be indicated by the gage so that if it is ance therewith, so that at the end of the operation the several sheets have corresponding top and bottom marginal spaces. Having described the invention I claim: A page margining attachment for typevvriting machines having an operating-r011 mounted for independent movement coaxiall-y with the platen of :a typeW-riti ng-machine, means for commnnicating forward. 10 step by step movement from the platen to saidoperating roll, an idle gu ide. roll, and a gage member consisting ofi an'endless plate or tape traversing said rolls and having graduations rep-resenting line spaces numbered consecutively in reverse order. In testimony whereof I affix 1n signature.
