I UNITED STATES v JAMES KELLEY BURLEIGH, OF NEW YORK,,N. Y., ASSIGNOR TO 'B. 86 H. UTILITY PRODUCTS, INC., NEW YORK, N. Y., A CORPORATION OF NEW YORK.

ATTACHMENT FOR TYPEWRITERS.

Application .filed October 16, 1922, Serial No. 594,779. Renewed July 6, 1926.

hly invention more particularly relates to a device for indicating the'cxact position of the sheet or letter in the machine; that is to say, how far it has progressed, so that the i typist may have visible evidence before her at all times as to how much margin remains at the end of the page orsheet.

In carrying my invention into elfect it is one of the primary objects of my invention to provide a paper support which forms an extension and continuation of the regular paper table and in connection with this support and on the front face thereof, so as to be plainly visible to the typist, I provide a i scale, marked off in inches, and l sub-divide this inch scale to exactly correspond with the single spacings of the typewriter; that is to say, the-distance between each two contiguous markings will measure up exactly to the amount of movement of the platen when it is shifted a single space. If the construction of the typewriter is such that in six shiftings ittravels one inch then -I provide the corresponding markings on my paper support and indicator. This is important as the readings of the indicator should designate truly the exact position of the paper.

Inasmuch as the spacings in standard typewriters now measure six to the inch I construct my implement in accordance with this.

Another feature of my invention is to pro vide the upper face of the extension. and

sheet support with an uninterrupted and smooth surface, so that the sheet or paper will glide over the same without possibility of tripping or buckling.

In order that my invention may bemore readily understood I will proceedto describe it in connection with the accompanying drawing which forms a part of this specification. 1

In these drawings, Fig. 1 shows a perspective View of a portion of a typewriter, more particularly the platen and the parts immediately associated with it; in this figure also my invention is shown attached.

, thereon.

14 indicates At 16 I show my improved indicator and j paper-support on which I provide my spacing markings 19 which I position six to the inch to'correspon-d to the present spacings now in use on standard typewriters; I secure this attachcment to the sheet support and apron 1% by means of retaining fingers 'lhese' fingers are integrally formed with the indicator and paper support 16 which is made of spring metal.

As will be seen by referring to the draw iug the central finger 18 constitutes a lower extension of the paper support and space indicator l6 and the space markings 19 are continued down this finger; this feature I consider very important. V

The sliding stop is shown at 20: it consists of an upright member 21, a flat sliding plate 22 and locking members 23.

Having thus described my invention the following is what I claim as new and useful therein and desire to secure by Letters Patent is: v

A-n attachment for typewriters comprising a paper guide member which constitutes a continuation of the standard forms of paper tables and provided with graduations thereon to indicate the relative position of the paper on which subject matter is being typed with respect to the platen of the machine, and means for removably securing the guide member to the paper table com rising retaining fingers for yieldingly engaging the w front and back of said paper table the finger engaging the front of said table being also provided with indicating graduations JAMEsKELLEY'BURLEIGIi.
