WITNESSES I INVENTOH NITED STATES PATENT Fries,
FOUNTAIN-PEN.
SPECIFICATION forming part of Letters Patent No. 594,098, dated November 23, 1897. Application filed July 14, 1896. Serial No. 599,066. (No model.)
To all whom it may concern.-
Be it known that I, FRANCIS J. PRIBYL, a citizen of the United States, and a resident of I-Iazleton, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Fountain- Pens, of which the following is a specification, reference being had to the accompanying drawings, forming apart thereof, in which similar numerals of reference indicate corresponding parts wherever found throughout the several views.
This invention relates to fountain-pens such as are usually employed for writing, drawing, and other purposes; and the object thereof is to provide an improved device of this class which is simple in construction and operation and which works upon the principle of a force-pump, the ink being pumped out of the reservoir into-or upon a pen, and the construction being such that any surplus ink out of the reservoir at the time the writ ing is finished may be forced or pumped back thereinto.
The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which Figure 1 is a central longitudinal section of my improved pen; Fig. 2, a section on the line 2 2 of Fig. 1; Fig. 3, a section on the line 3 3; Fig. 4, a section on the line 4 4; Fig. 5, a back view of an ink-feeding plug which I employ, and Fig. 6 a side View thereof.
In the practice of my invention I provide a tubular reservoir or holder 7 of the usual form, and which is closed at one end and screw-threaded at the other, and connected therewith is a tube 8, having a screw-threaded extension 9, which is adapted to be connected with the reservoir or holder 7, as shown in Fig. 1, and which is provided at its inner end with a tubular extension 10, on which is formed an annular flange or rim 11.
That portion of the tube 8 which is connected with the holder or reservoir 7 is smaller than the outer end thereof, and by means of this construction two annular chambers 12 and 13 are formed, the outer chamber 13 being larger than the inner chamber 12, and I also provide a sliding cylinder 14, which is mounted in the tube 8 and the outer end of which is provided with a longitudinal bore tension 10, formed on the screw-threaded end of the tube 8, and is provided with a nut or bur 18, at the inner side of which is mounted a packing 19, of rubber or similar material,
and passing over the inner end of the shaft 17 and the nut or bur 18 is a rubber or other elastic band 20, the ends of which are secured to the tubular extension 10 of the tube 8, and the packing 19 is secured to the shaft 17 adjacent to the nut or bur 18, and instead of Y the elastic band any suitable spring may be employed.
The outer end of the cylinder 14 is provided with a sleeve 21, which is secured thereto and which is free to slide in the outer end of the tube 8, and between said sleeve and the outer end of said tube is formed a longitudinal passage 22, through which the air passes in the operation of the device, as hereinafter described, and between the outer end of the sleeve 21 and the cylinder 14 is an annular space 23, into which the pen 24 is inserted, said space being adapted to serve as a penholder. The outer end of the cylinder 14 is also provided with an ink-feeding plug 25, which is provided at its end with a cylindrical extension 26, adapted to be inserted into said cylinder 14-or the central bore formed therein, and the outer end of the said plug 25 is formed like a pen, and said plug is provided on its upper side with a longitudinal groove 27 through which the ink passes, and at each side of the pen-shaped portion of -the outer end thereof is a slot 28, and this feeding-plug may also serve under certain circumstances for a pen, especially when heavy or coarse writing is required.
The point of the pen 24 projects beyond the point of the feeding-plug, as shown at 29, and I also provide a removable tubular cap or cover 30, which is closed at its outer end and provided with an enlarged inner end, as shown at 31, and this cap or cover is adapted to be connected when the pen is not in use with the outer end of the tube 8, as shown in said figure, and this connection is preferably made by means of an ordinary slip-joint.
The operation will be readily understood from the foregoing description when taken in connection with the accompanying drawings and the following statement thereof: The reservoir or holder 7 is filled with ink in the usual manner, after which the plug 8 is secured therein in the usual manner. When it is desired to write or draw with the pen, the point thereof is pressed on the paper, and this operation forces the cylinder 14 inwardly, and the shaft 17 is also forced inwardly, oarrying with it the nut or bur 18 and the packing 19, the elastic band yielding to permit of this operation, and the air in tube 8 is forced into reservoir through the tubular extension 10, and when the pressure on the point of the pen is removed the elastic band 20 returns the cylinder 14: to the position shown in Fig. 1, thus producing a vacuum in the tube 8 by the withdrawal of piston 14, which the ink, assisted by the pressure of air within the reservoir, speedily enters through the tube 10 and flows through the ports or passages 16 in the cylinder 14 into the central bore 15 and out through the ink-feeding plug 25 or through the slot 27, formed in the back thereof, to the point of the pen.
The operation of pressing the point of the pen upon the paper and allowing the ink to flow into or be forced into the tube 8 may be repeated as often as desired, and if any ink remains in said tube 8 when the writing is finished the pen is held with the point up and the cylinder 14: is operated by means of the projecting end thereof or the feed-plug 25, so as to force the ink in the tube 8 back into the reservoir or holder.
It will be understood that when the reservoir or holder is held so that the pen will point upwardly all the ink in the tube 8 and in the cylinder 14 will flow back into the screw-threaded extension 9 of the tube 8, and by pressing the cylinder inwardly said ink will flow back through the tubular extension 10 of the tube 8 into the reservoir, and this operation may be repeated as often as desired. It will also be observed that the inner end of the cylinder 14 is substantially of the same size as the chamber 12 in the inner end of the tube 8, and said cylinder 14 is adapted to force the ink back into the reservoir or holder, and in the normal position of the parts the elastic band 20 keeps the packing 19 seated on the end of the tubular extension 10 and closes the passage therethrough and the ink cannot escape or flow out through the tube 8 and the cylinder 14.
This device is simple in construction and operation and perfectly adapted to accomplish the result for which it is intended, and it is evident that changes in and modifications of the construction herein described may be made without departing from the spirit of my invention or sacrificing its advantages.
The packing 19 is not absolutely essential, and the nut or bur 18 may serve as a suitable head to close the end of the tubular extension 10, and in the operation of the device, as hereinbefore described, air passes through the longitudinal space 22 between the outer end of the tube and the sleeve 23, or simply around the outer circumference of the sleeve 23 and into the reservoir or holder and also into the tube 8, and this space 22 preferably consists of a longitudinal groove, as shown in Fig. 2.
Having fully described my invention, I claim as new and desire to secure by Letters Patent 1. A fountain-pen comprising a tubular reservoir, or holder, which is closed at one end, and open at the other, a tube mounted in the open end thereof, and provided with atubular extension which projects into the reservoir, a sliding cylinder mounted in said end tube, and provided with a shaft which projects through said tubular extension, and on which is mounted a packing which is adapt ed to close the inner end of said extension,
said shaft being provided with longitudinal grooves, and with an elastic band which serves to keep the packing seated, on the inner end of the tubular extension, and said cylinder being also provided at its outer end with a central bore, the inner end of which is provided with side ports or openings,which form a communication between the annular chambers 12 and 13, and the said bore, and said cylinder being also provided at its outer end with a suitable feeding-plug, and a penholder, substantially as shown and described.
