Specification of Letters Patent.

.To @ZZ wtom t may concern.-

Be it known that I, HERMANN KRANDT, a citizen ci' the German Empire, residing at No, 67 Leipzigerstrasse, Berlin, GermanyI have invented certain new and useful Improvements in Blotters or Blotting-Pads, of which the following is a description.

BThe present invention relates to blotters or blotting-pads; and it consists, essentially, in constructing the same so that the blottingpaper comin from a roll within the pad is guided over t 'e blotting-surface and clamped 1n position thereon. When used up, the clamp is released and a new length of the paper pulled over and clamped fast on the letting-surface.

The invention also comprises means for guiding the pa er over the blotting-surface, so that both si es of each len th of blottingpaper may be used up wit lout, however,

aving to turn the pa er over by hand.

In order to render tlie present specification easily intelligible, reference is had to the accompanying drawings, in which similar letters of reference denote similar parts throughout the several views.

Figure 1 is a side elevation of one form of blotter embodying the invention. Fig. 2 is a longitudinal section through the same. Fig. 3 is a central cross-section showing the paperroll partly in elevation.

In the embodiment of the invention as illustrated the blotter consists of the frame formed by the side members c c, the end rolls g 'i h k, su ported to turn in the connectingpieoes 'r r y means of the pivot-screws e e e e, and the central roll lfor the pa er, said roli being mounted on a spindle p an having one end squared, Fig. 3, to engage one plate o and a thumb-screw g on the other end. The side members or lates c c c c have each a pair of hooks d d d dat each end which engage over the pivot-screws e e e e, and thus heid the frame together, owing to the elasticity of the blottin -surfaces, which are formed by the bont stes a and b. These lates are recessedpat each end, Fig. 3, to a low s ace for the guide-foils, and the remaining en s ofthe said plates are bent round and engage the reduced parts t of the guide-rolls, as will be clearly seen from Fi 3.

At one end of tie blotting-pad the end plates r are provided with lugs s, in which the clamping member m for the end of the blotting-paper is mounted, and when it is required to clamp the end of the paper this inernber is turned up into the position shown in Fig. l. In order to give a finish to the edges of the plates a and b a thin sprin is provided at each side, as at o, said spring eing bent round at its ends to engage over the reduced ends of the rolls g ii. i lc, respectively, and having thereon n piece of rubber tubing 'n or the like soft material, so that the blotting-pad may be easily and conveniently grasped. These springs may be retained the proper position apart at the center by means of braces, as shown at o in Fig. 3.

When the pad is intended for using both sides of the blotting-paper, the paper coming from the roll l is passed in the direction of the arrows first over the guide-roll g, then over the blotting-surface a, round the nido-roll 1i., under the paper-roll l, and over t e guideroll t', then over the biotting-suraoe b, guideroll if, and under the clamping-bar m. Thus it will be seen that both sides of the blottingpaper will be used up, since the side on surace a is the reverse of that on surface l, as will be readily understood.

In order to take out the roll l and put a new roll of paper on the saine, the plates a and o are slightlyY compressed in the direction of the arrows :c :c of Fig. 2, so that the hooks d at one end of one of the bars o can be freed from the screws e, the thumb-nut g having rst been nnscrewed and the spindle p taken out, or the bar c, which will yield slightly being'iifted over the end of the same an turned into the position shown in dotted lines in Fig. i. The new paper-roll is then placed on the roll l and the parts returned to their original positions after the end of the paper has been passed over the guide-rolls in the manner reviously set forth. The friction of the roll xi and that between the part of the paper passing over the foil between the rolls and t and rubbing against the under part of the pa er-roll will be sufficient to keep the paper rawn properly tightly over the blotting-surfaces and clamped by the clampingbar m.

The construction of the blotter could be varied in a great many ways, and I wish it to be clearly understood that the present invention is not restricted to the construction shown, althou h this appears at present to be Well adapte for the purpose.

I claim, broadly- 1. Ablottin -pad havin blotting-surfaces and a paper-ro I mounted etween the saine and means for guiding the paper over tb IOO said surfaces consecutively and for turning paper in the form of en S over and between the paper over between the said surfaces so I the two blotting-surfaces, so that op osite that different sides of the said paper will be sides ofthe paper will be'outside et eac i suroutrnost on each Surface, and means for face.
