v PROTECTOR TABLET. APPLICATION FILED IULY 24, 1916.

I awmmtozr WILLIAM S. STAIARS, OF PHILADELPHIA, PENNSYLVANIA.
Specification of Letters Patent.
Patented Oct. 17, 1916.
Application filed July 24, 1916. Serial No. 111,029.
To all 'whom it may concern:
Be it known that I, WVILLIAM S. STALARS, citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Protector-Tablets, of which the following is a specification, reference being had therein to the accompanying drawing.
This invention relates to an improvement in protector tablets.
In the use of manifold books it is usual to place carbon sheets between the various thin sheets in instances as many as four or five carbon sheets being employed for duplicating purposes. The carbon sheets are usually of a size somewhat longer than the book sheets and invariably project below the edges of the sheets of the book. WVhen in use the cuff and edge of the sleeve of the user come in contact with the projecting carbon sheets and are soiled.
The present invention is designed as means for protection against such objectionable occurrences.
The invention also comprehends the provision of a backing card or sheet for the various leaves receiving the original and duplicate copies of the writing.
The invention also comprehends a structure which will serve as an arm rest when the writing is to be placed near the bottom of the sheets.
In the accompanying drawing there is shown a construction embodying the invention, but it is, however, understood that the underlying principles can be embodied in structures difierent from that shown and described without departing from the nature and principles of the invention.
In the drawing: Figure 1 is a perspective view of an order book having the invention associated therewith. Fig. 2 is an edge view of the same showing the protector positioned outwardly; and Fig. 3 is a detail perspective view of a protector tablet.
In the drawing A represents the manifold order book of any approved type, the same being composed of a multitude of sheets.
A represents the protruding ends of the carbon sheets at the lower ends of the entry sheets.
It is usual to interpose several carbon sheets between the entry sheets and the duplioating sheets, and as stated above the edges of the carbon sheets invariably project below the edges of the book sheets.
B represents a tablet formed conveniently of hard, card or fiber board or any other substantially rigid material, the same being of a size slightly longer than the blank surfaces of the book sheets so that the outer end thereof will project beyond the ends of the book sheets. Secured to the outer end of the tablet sheet B is a protecting sheet C of card board or other substantially stiff material. The part C and the part B are conveniently united by a flexible strip D that forms a hinge. The parts are so united that the uniting hinge portion has a suflicient width as between the adjacent edges of the part C so that the part C can be readily folded over onto the face of the entry sheet of the book as shown in Fig. 1 of the drawing. The sheet C is of a length less than the length of the sheet B so that there is writing space left above the free edge of the sheet C when folded onto the entry sheet. In use the operator positions his carbon sheets below the entry and duplicate sheets of the book, then places the tablet sheet B below the lowermost sheet upon which a duplicate is to be made adjusting the tablet well up between the leaves, and then folds the protecting part C over onto the upper face of the original entry sheet. This completely envelops the protruding ends of the carbon sheets and pre vents the cuff of the user from coming in contact therewith. As the entries are made to the entry sheet the operator moves the protecting tablet down or out and when the latter is projected to the point where the free edge of the part C is adjacent to the lower end of the entry sheet the combined stiffness of the parts C and B constitutes an effective hand rest. During the entire operation the protruding ends of the carbon sheets are inclosed and the stiff backing tablet sheet B enables the operator to produce clearer and better impressions through the carbon sheets.
The invention is materially different from an ordinary hand rest, and as far as known is the first to provide a means for overcoming the objection of soiling the apparel of the operator during the entry of the items, and also to provide a hard tablet surface upon which to write.
' In addition to the above two advantages there is the added advantage of a hand rest for entry toward the lower entries made on the lower part of the entry sheet.
An advantage of having the flexible joint between the two parts B and G is that the device will accommodate a small number or a large number of carbon sheets and that particular is characterized as an extensible joint so that the distance between the folded over protecting sheet and the tablet sheet can be varied according to the requirements of use. lVhile it has been found that a smooth relatively stiff card board is satisfactory, manifestly thin metal plates could be employed in lieu thereof.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
1. Av protecting tablet for manifold books comprising a tablet part, a protecting part, and a connection between the outer portions of the tablet and the protecting part, the length of the protecting part being less than that of the length of the tablet part for the purpose specified.
2. In combination with a manifold book having a plurality of leaves, a carbon sheet detachably positioned between the leaves, and a removable protecting tablet part below the carbon sheet, a protecting part ar- I Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Eatents.
