Ap licati fil d November 20, 1900. Serial No. 37,128. (No model.)

While the closure of the ink-receptacle I to Referring to said drawings, 1 2 represent a the atmosphere will prevent leakage of the pair of pen-arm drums, to which are conink through the supp1y-openingz' when the nected by cords 3 in the usual way a pair of pen P is out of said opening a slight amount I00 pen-carrying arms 4 5, hinged together and of drip may take place just as the pen P is becarrying a pen P. The movements of these ing introduced into or withdrawn from such into a waste-receptacle located beneath the ink-receptacle I, as shown in Fig. 2.

Any suitable form of receiving-pen may be used in connection with this ink-receptacle,

which is capable of entering opening 4? and contacting with the ink therein; but I prefer the one shown, which will now be described. This pen consists of a stem p, provided at its writing end with intersecting longitudinal slits 19, extending from side to side of the stem and upwardly some distance from the writing-point thereof,as shown in Fig. 3. The stemp is also provided with a central inkholding orifice 19 above the writing-point of the pen and with which each of the slots 19 communicates. This construction of pen is preferable,because of the rapidity with which it may be supplied with ink, because of its large holding capacity, and also because of the uniformity of flow therefrom in writing.

The manner of using the ink-Well I and inking the pen P therefrom is as follows: When the receptacle I has been filled with ink and then-closed by stopper t, the ink of course has a tendency to flow out through the side opening a As it enters said opening, however, it seals the receptacle I, the outside atmosphere then permitting only enough ink to escape to cause the weight of the ink and the pressure of air within the receptacle I to balance the pressure of the outside atmosphere, when the escape of ink will be arrested. The ink thus escaping will travel down the lip i into the waste-receptacle i". The receiving-pen P being moved by drums 3 4 toward the ink-receptacle I its end will pass through the opening 13 into contact with the ink in the receptacle, when its slits 19 and ink-holding orifice 19 will be supplied with ink by capillary attraction. The capacity of the slits p and orifice 10 exceeds that of the opening 7?, so that as thepen thus takes up its supply of ink a sufficient quantity of ink will be withdrawn from the opening 1' to permit a small quantity or bubble of air to enter the receptacle I to compensate for the ink withdrawn, thus maintaining a constant supply of ink at the opening by gravity. The opening 11 and the end of the pen P which enters said opening are, as will be observed, so proportioned relatively to each other as to size and shape that when said pen rests in said opening, as it does when the apparatus is not in use, it will seal said opening, and thereby preserve the ink within the receptacle from the effects of the atmos phere.

The invention is not limited to the precise construction of inking device and pen shown and described, and modifications and changes may be made therein without departing from the spirit of the invention, broadly considered.

What I claim is- 1. In a telautographic apparatus the combination with'a pen and its carrying means, of an inking device comprising a closed receptacle provided with aside opening adapted for the passage of the ink-receiving end of the pen into contact with the ink within the receptacle, substantially as described.

2. In a telautographic apparatus the combination with a pen and its carrying means, of an inking device comprising a closed receptacle provided with a side opening adapted for the passage of the ink-receiving end of the pen into contact with the ink within the receptacle, the ink-holding capacity of said opening being less than that of the pen, substantially as described.

3. In a telautographic apparatus the combination with a pen and its carrying means, of an ink device comprising a closed receptacle provided with a side opening adapted for the passage of the ink-receiving end of the pen into contact with the ink within the receptacle, a waste-receptacle beneath said opening and means for conducting ink dripping from said opening into said waste-receptacle, substantially as described.

4. In a telautographic apparatus the combination with its pen-carrying means, of a pen comprising a stem the writing end whereof is slit longitudinally and an inking device comprising a closed receptacle provided with a side opening adapted for the passage of the ink-receivin g end of the pen into contact with the ink within the receptacle, substantially as described.

5. In a telautographic apparatus the combination with its pen-carrying means, of apen comprising a stem the writing end whereof 'is provided with longitudinal intersecting slits and an inking device comprising a closed 1 receptacle provided with a side opening adapt ed for the passage of the ink-receiving end of the pen into contact with the ink within the receptacle, substantially as described.

6. In a telautographic apparatus the combination with its pen-carrying means, of apen comprising a stem the writing end whereof is provided with longitudinal intersecting slits and with an inner ink-holding orifice communicating with said slits and an inking device comprising a closed receptacle provided with a side opening adapted for the passage of the ink-receiving end of the pen into contact with the ink within the receptacle, substantially as described.

7. In a telautographic apparatus the combination with its pen-carrying means, of apen comprising a stem the writing end whereof is slit longitudinally and provided with an inner ink-holding orifice communicating with said slit portions, and an inking device comprisinga closed receptacle provided with a side opening adapted for the passage of the ink-recei ving end of the pen into contact with 1 2 being so proportioned relatively to each other that when the latter is in said opening it substantially seals the same, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing r5 witnesses.
