UNITED STATES PATENT OFFICE.

HARRY ETHERIDGE, OF PITTSBURG, PENNSYLVANIA, ASSIGNOR TO THE WRITING TELEGRAPH COMPANY, OF NEW YORK, N. Y.

BALANCED PEN FOR AUTOGRAPHIC TELEGRAPHS.

SPECIFICATION forming part of Letters Patent No. 425,066, dated April 8, 1890.

Application filed October 11, 1888. Serial No. 287,796. (No model.)

To all whom it may concern:

Be it known that I, HARRY ETHERIDGE, a subject of the Queen of Great Britain, and a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, have i11- vented a certain new and useful Balanced Pen for Autographic Telegraphs, of which the following is a specification.

This invention has reference to fountainpens for use in connection with the transmitting-stylus or receiving-rod of an autographic telegraph.

The invention has for its object the devising of a fountain-pen which, when in operationiwill maintain a minimum pressure on the paper written upon and a pressure that will be uniform and not Variable.

A further object is to produce a pen having the characteristics stated which operates upon the principle of capillary attraction.

My invention will now be described in connection with the accompanying drawings, which form part of this description, and the subject-matter for which protection by Letters Patent is desired will be specified at the end of this specification.

I11 the drawings, in which like features are indicated by like figures of reference in the several views, Figure 1 is avertical sectional View of a fountain-pen nib embodying my improvements. Fig. 2 is aside elevation of the pen-nib disconnected from the reservoir, but connected with the transmitting-stylus or receiving-rod. Fig. 3 is a top plan view of the pen-nib. Fig. 4 is a cross-section of the pennib on the line 0000 of Fig. 5. Fig. 5 is an enlarged view of the point of the pen-nib. Fi 6 is a top plan view showing the reservoir and means for shielding the same, hereinafter described. Fig. 7 is a vertical section on the line 3 y of Fig. 6. Fig. 8 is a top plan view through the line 2 z of Fig. '7. Fig. 9 is a detail showing the construction of the opening for filling the friction-chamber, and Fig. 10 is a cross-section on the line 10 w of Fig. 0.

Referring now to Sheet 1 of the drawings, containing Figs. 1 to 5, the pen-nib is indicated by 11 and will be essentially of the form shown, with a vertical limb which is adapted to dip into the reservoir 12 and with a curved limb in whose outer end the point 13, of platinum or other hard suitable material not subject to corrosion or wear, is secured. The pen-nib 11 is preferably madeof ebonite, and is adapted to convey the ink to the surface written upon on the principle of capillary attraction. In the top of the curved member of pen-nib 11 there is formed anarrow open duet, (best shown in Fig. 3,) which extends to the bottom of its vertical member, and through this duct theink passes to the point 13. The point 13 is preferably of the form shown in Figs. 4 and 5, is provided with a central duct, as shown, and is secured in place by springingit into the duct formed in the pennib, its shape being such as to make that practicable. Preferably on the bottom surface of the curved member of pennib 11 there is formed or attached a weight M, which is so proportioned with reference to the weight of the vertical member of the pen-nib in the fluid as to balance the pen-nib in such manner as to keep its point always resting on the paper with a minimum degree of pressure, thus insuring a minimum and uniform amount of friction between the point of the nib and the surface written. upon. The pivot 15, whereby the socket 16 of the transmittingstylus or receiving-rod is secured to the pennib 11, is located, as shown, approximately in a central position 011 the under surface of the curved member of the nib. By this means the balanced condition of the pen will not be disturbed in manipulating the stylus or receiving-rod, and the nib is free to swing or vibrate as it partakes of the movements of said stylus or rod. W'ashers a a serve to prevent the pen from. rubbing against the sides of socket 16.

Referring now to Sheet 2 of the drawings, showing Figs. 0 to 10, the stand or case which contains the autographic writing apparatus is indicated by 18, and 19 designates the usual opening through which the stylus or rod projects. The paper to be written upon is indicatcd by 20, and it is so arranged as to pass from the reel (not shown) through longitudinal slot 21, made in stand 18, thence through the inclined slot 22, and along the surface of the table as the pen moves over it. Screwed to the top of the table in proper relation to slot 21 and opening 19 there is a frame 23, preferably circular and of metal and provided with a vertically-projecting flange 24. This frame is adapted to receive the dome 25, which serves to shield the pen and the inkreservoir from dust and protect them from interference. Upon the table 18, within the space covered by said dome and in proper relation to the opening 19, through which the rod or stylus which supports the pen-nib projects, there is arranged the ink-reservoir 12, into which the vertical member of the pennib 11 dips, as indicated in Fig. 1. The frame 23 is provided with a slot 26, through which the paper passes from beneath the dome as it leaves the pen. Beneath stand 18 there is secured air-tight by means of screws 27, a receptacle 28, of ebonite and of the form shown, with an opening 29 in the center of its bottom, having vertical walls 30, which extend within said receptacle a sufficient distance to form a friction-chamber 31. This chamber contains a quantity of fluid, into which projects the vertical walls of the German silver float 32, which latter is secured to the stylus or rod 17, which carries the pen-nib, by means of brass piece 33, soldered or otherwise secured to said float and stylus or rod. The chamber 31 is replenished through the openin gin its side, which is closed by the ebonite plug 34:. (Shown in detail in Fig. 9.) Between the ebonite receptacle 28 and the table 18, and between the frame 23 and said table, soft rubber 35 may be employed as a packing, as indicated.

Instead of

slots

21 and 22 in the table, I may make aslot, as 36, opposite slot 26 in the frame 23 and allow the paper to pass therethrough.

The function of fioat 32, which is connected to stylus or rod 17, is set forth in the United States patent granted to Robertson, No. 353,593. The chamber of the float in the present instance is secured air-tight to the under side of table 18 to prevent dust, &c., from collecting within the dome through opening 19.

The advantages incident to the herein-described construction of the pen-nib 11 are cheapness, ease of cleaning, and the avoidance of the necessity of withdrawing the nib when the pen is required to be refilled.

I am aware of the patents granted to J. II. Robertson, Nos. 353,592 and 353,593, but what is therein shown and described I do not claim.

Having thus described my invention,whatl claim as new, and desire to secure by Letters Patent, is

1. A fountain-pen nib provided with a capillary duct extending from end to end, pivoted on a suitable support, and having its writingpoint limb made slightly heavier than the other, whereby said limb may rest on the pa per with a slight and uniform pressure, substantially as described.

2. The combination,-with the receiving stylus or rod of an autographic telegraph, of a fountain-pen nib pivoted to said rod and having its writing-point limb made slightly heavier than the other, and a reservoir separate from the nib, substantially as described.

Signed at New York, in the county of New York and State of New York, this 21st day of September, A. D. 1888.

HARRY ETHERIDGE. iVitnesses:
