KARL GOSSWEILER, OF VIENNA, AUSTRIA-HUNGARY.

INK-BLOTTER.

Specification of Letters Patent.

Patented .Tune 18,1907.

Application filed November 12, 1906. Serial No. 343,110.

To a/ZZ whom t may concern:

Be it known that I7 KARL GosswEiLER, a citizen of the Empire of Germany, residing at Vienna, 48 Wolfganggasse, in the Empire of Austria-Hungary, have invented certain new and useful Improvements in Ink-Blotters, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in blotters of that type wherein the blotting paer is provided with a relatively solid base or oundation the paper and the base being united to form a composite blotter structure.

The object of this invention is to provide a blotter of the general character set forth wherein means usually employed for securing the blotter sheets to the base are entirely dispensed with and wherein the construction is such that the v blotter sheets will when the base is in place engage the same with sufficient force to unite and hold the parts in position.

According to my invention this feature is realized by uniting the several blotter sheets employed in such a manner that when the base or support is in place the blotter sheets will have sufficient resiliency to effectively engage the base.

AThe invention will be more fully described in connection with the accompanying Vdrawling and will be more particularly pointed ou't and ascertained in and by the appended claims.

In the drawings-Figure 1 is a side elevation of an improved form of blotter illustrating the main features of vmy invention and showlng a base or core inserted in place. Fig.

' 2 is an edge view of the blotter sheets showing the position that the same assume before the core or base has been inserted.

Like characters of reference designate similar parts throughout the dierent iigures of the drawing.

The invention will be described with relation to the specific/embodiment shown but it will be understood that the invention is not to be limited to such specific showing except for such limitations as the claims import.

According to my invention a plurality of sheets of blotting paper l), preferably of uniform size, are arranged in superposed relation with respect to each other. Adjacent their ends means are provided for securely binding said sheets together which means as shown consists of clips d formed of wire or other suitable material' adapted to sui-'round said sheets leaving end c projecting outwardly from said clips.

In order to provide requisite stiifness and afford suflicient holding surfaces I provide a base which is preferably in the form' of a core a adapted to be inserted between the superposed sheets of blotting paper b. The` core o is preferably oval or lenticular in form and is inserted in place between the sheets b by opening the same through pressure exerted on the ends c, the spreading of said sheets for insertion of the core rendering the former suiciently resilient and causing a frictional engagement of the core by the blotting sheets suflicient to hold the parts in assembled relation. The resilient action is caused primarily by the fact that the ends of the sheets are bound together in a fixed relation by the clips d and when the core a is inserted the spreading actiontends to change the fixed relation at the ends of the sheets by drawing or pulling inwardly on the uppermost sheets and thrusting outwardly on the innermost sheets. By providing the core in the form shown the parts orends h cause a sharp bend of the sheets near the clips d and this tends to force the sheets to assume the collapsed posif tion shown in Fig. 2. By means of this construction it will be seen that the blotting sheets b will engage the core very securely and will effectively hold the parts in assembled relation. It will be further noted that very substantial results would obtain even though the core a were not constructed as shown since the clips el would always tend to hold the ends c in Xed relation and the result of a spreading movement of'any extent or kind would tend to clamp the sheets upon the base.

In order to facilitate removal of the outer l soiled sheets all of the sheets may be perforated as at f and separately torn off in the usual manner. y

The device of my invention is especially adapted for use in oflices since the core can be used indefinitely with .new sets of sheets.

This arrangement is' also advantageous to the manufacturer and seller in view of the fact that the parts can be packed and shipped separately and assembled by the user. In view of the fact that a single core would outlast a number of sets of blotting paper a relatively small number of cores would be made whereas a relatively large number of sets of blotting sheets would be IOO IOS

made and the latter could be packed and shipped in the flat or collapsed position shown in Fig. 2.

I claim:

1. A blotter comprising in combination, a plurality of superposed sheets of blotting paper, means uniting the ends of said paper in ixed relation, and a lenticular core inserted between and spreading said sheets, the resultant spring action of said sheets holding said core in place.

2. A blotter comprising in combination, superposed sheets of blotting paper, means uniting the ends of said sheets in fixed relation, and a core inserted between and spreading said sheets, the resultant spring action of said sheets holdin0` rsaid core in place, said core being located between the points of said uniting means.

` 3. A bl'otter comprising in combination, a plurality of sheets of blotting paper, means for connecting said sheets at the ends thereof, and means for spreading said sheets between the uniting means whereby the resultant spring action of the sheets may serve to retain the parts in assembled relation.

In testimony wh'ereor1 I hereunto aflX my signature in presence of two witnesses.
