. LETTERING -DEVICE.

" a 7 Application filed February This invention relates to improvements in lettering devices and particularly to that kind of lettering deviceshown and described ;:f, 1 611,14O, dated inmy U. S. Letters Patent ,-December. ltth, 1926., I; j

The primary object of theinvention resides in .a lettering device in which'a series of characters are .marked out upon a disk, and f which.charactersinay be brought into registry with a suitable indicating ,,n1ark, and a letter or numeral .printed by moving a sharppointed lettering pen orpencil about the walls of the cut-out character and which device is adjust-ably mounted upon a T- square for, movement over the surfaceof the ,paper topbe printed upon.

- -Another object of I he inventionis'to em bod'y: a lettering deviceupon a T-squareso that-the sameis. alwaysmaintained in a horizontal position to assure perfect alignment of the characters as they are printed. A

Another object of the invention is'toprovide a lettering device in which the circular disk orwstencil maybe locked after the se- .,lected -characters to .be printed have been movedtothe proper adjusted position and a means whereby the characters to be printed may be; accurately spaced from the last printed .character.

-Z A further ob'ect is: to provide a lettering V device for'attachment to T-squares which is simple in construction, inexpensive of manufacture, and simple of operatlon. withthese and other-ob ects-in view-the invention resides in certainnovel construc-' -tion and combination and, arrangement of W I .Whih

The disk;25.is of atransparthe free end thereof The outer free ends of the arms 22 are bent atfrightangleto provide legs 28 for spacing the circularflisk and'arms irom the surface of the paper'to be printed upon. i The circular disk 25 is transparent so as tobe seen through and is divided -up;i'nto a plurality of concentric fields each of whichisprovided with characters 29 infthenature ofletters "or parts of lettersottlw alphabet and numeralsand I an ' Q which are cut 'outtherefrom so thatthe disk in realityis no more than a stencil; "The outermost field contains the larger size-char acters but which gradually diminish xincsize toward the axis of the disk. The disk 25 is supported above the paper by the 'bridgepiece 24 and by a crosspiece 30 which connects the arms 22 adjacent-their pointv of contact withjt-he straight edge of the T- square.
