:SPECIFICATION forming part of Letters Patent No. 425,673, dated April 15, 1890.

Application filed December 13, 1889. Serial No.3 33,641. (No model.)

To all whom t may concern: thereof acting as a float and lifting the open Be it known that I, JOHN HEBERLING, a mouth off the bottom of the ink-reservoir to citizen of the United States, residing at Rochpermit the ink to flow freely to the interior ester, in the county of Monroe and State of of the collapsible or air-compressing chamber 55 5 New York, have invented new and useful to supply the consumption taking place in Improvements in Fountain -Inkstands, of the fountain-cup. which the following is a specification. It is also my purpose to provide an ink- My invention relates to that type of inkstand of this type in which the ink shall be stands in which a fountain-cup is lled and caused to flow to and from the fountain-cup 6o ro emptied by the flow of ink to and from a resat each dip of the pin, means being provided, ervoir or chamber communicating with said however, wherebyT a permanently-remaining cup. supply may be given in the fountain-cup for It is the purpose of my invention to provide any required period and removed at intervals, an inkstand of this type in which the flow as may be necessary. 65 I 5 and return to and from the fountain-cup shall The invention consists in the several novel be effected by a compressible and expansible features of construction and new combinaelastic cup mounted upon the lower portion tions of parts hereinafter fully set forth, and of the tubular stem, which also carries the then definitely pointed out in the claims folfountain-cup, the said elastic cup seating upon lowing vthis specification. 7o zo its open neck or mouth upon the bottom of To enable others skilled in the art to pracan ink-reservoirwith which, however, it has tice my said invention, I will describe the no positive connection, whereby the eXpansame in detail, reference being had to the acsion of the air by change of temperature companying drawings, in which-- within the inkstand proper shall not have the Figure l is a central vertical section of an 75 2 5 effect of iiooding the fountain-cup, while the inkstand, showing my invention. Fig. 2 is a elastic cup by which the fountain is supplied similar section showing the same parts in a shall be shielded from such accidental eXpandifferent position. Fi g. 3 is an elevation showsion, the air-compression by which said cup ing the device locking the fountain-cup in is illed being wholly confined to said elastic that position in which it affords a permanent 8o 3o cup and being wholly removed from the main supply of ink. Fig. I is a detail perspective ink chamber or reservoir. of the collapsible cup, the tubular stem, and

It is my purpose also to provide afountainthe fountain-cup mounted thereon. inkstand wherein the supply to the fountain- In the said drawings, the reference-numeral cup shall be effected by acontracting and exl denotes the body of the inkstand, which 85 35 panding cup, the elastic portion of which is may be of any preferred form, size, and ornapenetrated by the tubular stem which commentation and constructed from any matemunicates with and carries the fountain-cup, rial suitable for the purpose which will not the construction being such that the elastic readily corrode bythe acids of the ink. This cup or vessel shall lie in and be supplied from body incloses a reservoir 2 of any shape and 9o 40 the ink-reservoir of the stand, from which the size preferred, a central depression or chamink fiows to the interior of the elastic cup at ber 3 of small diameter and shallow depth or after each rise of the fountain-cup. v In being formed in the bottom, although this is other words, I combine with any ordinary ink not absolutely essential. reservoir or chamber an elastic collapsible The reservoir 2 is closed at the top by acap 95 45 cup or auxiliary reservoir, consisting of an or cover 4, which is formed of any suitable mainverted vessel partly filled with air and havterial-such as hard rubber-and connected ing its closed collapsing upper portion peneto the body by any known or preferred form trated by the tubular stem of the fountainof joint which will prevent the escape 0f the cup, which drops within said collapsible chamink should the inkstand be capsized. In the roc 5o ber to a point where its open end is submerged, cap or cover et 1s formed a central socket-bearsaid chamber or cup at each full expansion ing 5 of ordinary construction, within which therewith.

is arranged a tubular stein 6, having a neck 7, which closely fits the upper part of the socket. This stem is prolonged to extend nearly to the plane of the bottom of the reservoir 2, and upon the lower part thereof is mounted a vesselor cup 8, having an expanded collapsible closed portion 9 and a more, rigid open neck or mouth 10, which, although formed wholly or in part of yielding or elastic material, is intended to yield only so far as to form a practically tight joint at the point where it seats upon the bottom of the reservoir 2 and around thecentral depression 3. The elastic and collapsible portion 9 islpenetra'ted by the tubular stem 6, which centrally overhangs the recess or depression 3, the point of penetration being sealed by nuts or washers 12, turned onua threaded portion of the stem and between `which the material is compressed. A fountain-cup 13 of any suitable construction is mounted on the stem and communicates On the stem is also mounted a washer 14, which lies normally against the lower surface of the socket-bearing and closes the reservoir againstthe accidental escapeof ink. p

The reservoir 2 being partly filled with ink,

the cover is placed thereon, thereby submerging the collapsible cup, or nearly so, and producing therein a compression of air, whereby the ink is allowed to rise in the `neck 10 far enough to submergc the open end of the tubular stem 6. The vessel or cup under these conditions becomes a float and tends to rise by its own buoyancy, and if the fitting at the socket-bearing is ordinarily accurate it will Lrise until the neck 10 is slightly raised from the bottom of the reservoir-'2, thereby permitting ink to dow from the latter into the central depression 3 and into the neck 10 of the cup. The further rise of the latter is limited by the washer 14, seating upon the socket-bearing 5. When the fountain-cup is pressed downward, the neck 10 seats upon the bottom of the reservoir '2 around the recess or depression 3 and forms a practically tight joint, which prevents the ink fromy entering or escaping. Y A further pressure now causes a partial collapse of the elastic portion 9, compressing the airf therein and driving the ink up through the tubular stem 6 into the fountain-cup, filling the same, the stem atthe same time sinking within the central depression 3 until an elastic or yielding collar or packing 15, mounted on and surrounding its open end, seats upon the bottom `of the depression and closes the stem, thereby retaining the ink which fills the fountain-cup as long as this position and engagement of parts are preserved.

The ink may be caused to flow to the fountain-cup and recede therefrom each time the pen is dipped, or the cup may be filled and its supply retained until exhausted, To eect this result, I tap into the cover or cap 4 a setvscrew 16, having a cam-collar 17, which may :be milled, and which by rotating: said screw in the manner described, such device being independent of and separate from the tubular stem and socket-bearing therefor.

\ The washer14 is applied `to the stem in` any manner-as, for example, by being slipped over a circumferential series of corrugations 19. It will be seen that I may dispense with the central depression or recessj3 and use a reservoir having a perfectly-fiat bottom; but in this case it will be preferable to increase the height of the neck 10 ofthe the vessel or cup 9.

It will be seen that the elastic expansion l of the collapsible inverted cup after each flow of ink to the fountain-,cup will not only `restore the latter to normal position, but will tend to preserve the necessary quantity of y.

ink within the neck of the elastic cup and in the depression surrounded by it.
