8 Claims.

lVIy invention relates to inkstands.

The object of my invention is to provide an inlrstand construction comprising a main reservoir for ink and an ink-cup which is lled by ink supplied from theV main reservoir, and which embodies means or raising the ink by causing a partial vacuum to be created above the inkcup and submitting the normal atmospheric pressure to act above the surface of the ink in the main reservoir to force ink therein to a higher level where it may overflow into said ink-cup, or be maintained at a higher level by suitable means.

A further object is to provide an inkstand with a dip opening formed to support a pen-holder therein with a pen carried thereby extending into the ink, the pen-holder serving to close the dip when resting therein.

A further object is to provide an inkstand which may be made of glass or plastic materials that will not deteriorate and so formed that no air-tight joints are required in its construction and in which the cost of the materials and time required to assemble the parts are both reduced to a minimum.

Further objects and features of construction will be hereinafter fully set forth.

Referring to the drawings which form a part of this speciiication:

Fig. l is a plan View of an inkstand which discloses a preferred form of outline, and

Fig. 2 is an elevational sectional View on line 2-2 of Fig. i, showing the cover and depending cylindrical portion resting in their normal position thereon.

Fig. 3 is the same view as that of Fig. 2, except that the cover portion has been removed and the central cylindrical portion in which the ink-cup is formed, is shown to be formed separate from the body portion whereas in Fig. 2, it is shown to be integral with the body portion.

Fig, 4 is a vertical sectional view showing the central cylindrical portion, hereinafter referred to as the cup portion, held in position by a depending cylinder which rests on the cover and is connected to the lower end of the cup portion in integral relation.

Fig. 5 is a vertical sectional view of a construction in which the cup portion is made of soft vulcanized rubber and is provided with a vacuum cup at its lower end by means of which the cup portion is prevented iromliiting during the cup filling operation.

Fig. 6 is a cross sectional view on line 6--6 of Fig. 5, and

(Cl. 1Z0-61) Fig. 7 is a similar View showing the side of the cup portion as iiattened to provide a passage for ink, instead of a round hole formed in the said portion, as shown in Fig. 6;

Fig. 8 is a vertical sectional View of another form of construction in which an outer cylinder is used to support the cup portion, and

Fig. 9 is a view of the bottom of said outer cylinder showing passages for ink formed therein, said cylinder and cup portion being formed integral at their lower ends.

Fig. 10 is a vertical sectional view disclosing another way of securing the cup portion to the base of the body portion.

Fig, 11 is a vertical sectional View disclosing a jar in which is located a cup portion and sleeve portion which cooperate to raise ink in the same manner as disclosed in Fig. 10 but instead of the upper end being formed to support a pen-holder, a cork is used which extends laterally over the entire upper end of the sleeve, said cork being removed to allow a fountain pen to be filled from the ink-cup.

Fig. 12 is a plan View oi the jar shown in Fig. Y 11.

Fig. 13 is a vertical sectional view in which the top end of the cup portion is shown to be located above the inner top side of the reservoir, and its bottom end secured to the body portion of the Well by cement or other suitablemeans.

By referring to Fig. 1l, the principle of operation will be readily understood, and in so far as I am aware, is new in its application to an inkstand.

With ink in the jar constituting the reservoir, and the cork fitting in tight relation into the upper end of the sleeve, by raising the sleeve the air is raried in the ink-cup and space above the same, causing the atmospheric pressure above the ink in the jar to force ink upward between the sleeve and cup portion and overflow into the cup, and its return or downward movement will force all surplus ink back into the reservoir, after which the cork may be removed and a pen filled with ease.

i5 indicates the body portion formed with a reservoir IS in which is supported a cup portion l1, the cup I8 of which islocated in the upper end of said cup portion.

The cup portion may be made integral with the body portion as illustrated in Figure 2, or connected thereto by cement as illustrated in Figure 13, or may simply rest upon the bottom of the reservoir if made heavy enough to prevent its lifting when the partial vacuum is created above the cup in the act of drawing ink thereinto, as will be readily understood.

However, when the cup portion is made of light material which lifts during the lling operation of the sleeve movement, it is necessary to hold the cup portion in its normal position of rest by suitable means, and the means required depends upon the shape of the reservoir of the body portion on which the cup portion rests or over which it is supported; the construction being designed to hold as much ink as possible and to permit practically all of the ink to be eventually supplied to the cup.

Therefore, if the bases containing the main reservoir i have already been made and it is desired to use them with the other novel parts described herein, the constructions illustrated in Figures 4, 5 and 8, may usually be used therewith, but when the entire inkstand is made from new moulds, the constructions illustrated in Figures 2 and 3, is preferred.

Referring now to Fig. 2, it will be seen that the cover and body portion is made of glass or plastic material, the cover I9 extending entirely across the open upper end oi' the reservoir and a depending sleeve portion Z extending downward therefrom, and formed with an inner circular wall 2| which normally rests in close contact with the outer wall 22 of the cup portion, the adjacent surfaces being inclined relative to the vertical topermit easy drawing in the moulding operations, as will be readily understood.

The lower end or bottom of the reservoir is preferably formed with a deep circular recess 23 into which the lower end of the sleeve extends as shown, the object being to prevent air from flowing from the reservoir between the sleeve and cup portion when the ink is low in the reservoir and the sleeve is being raised in the act of lling the ink-cup.

The upper end of the sleeve or cover, as the case may be, is formed with a conically formed dip opening 24 in which is fitted a soft rubber seat 25 to provide a tight joint between the lower end of the pen-holder used with the stand, to insure proper lifting of the ink to the ink-cup in the lling operation, but a cork, or a flat piece of paper laid upon the flat surface 86 of the cover will answer the same purpose.

As the cover is raised the space between the sleeve and cup portion increases and forms a passage for ink leading to the dip-cup.

In Figures 4, 8, and 11, the ink cup portion is separated a limited distance from the adjacent sleeve to form an annular passage 2 Ybetween them, and in Figures 5, and 10, a vertical passage 21 is formed within the outer wall of the cup portion, and the adjacent sleeve portion is tted to slide closely to the outer wall of the cup portion instead of between the walls.

In Figures 4 and 8, the outer cylindrical sleeve 28 is formed integral with the cup portion at their lower ends as shown; in Figure 4, the said cylinder being suspended from the cover by a flange 29 and its inner diameter is increased to allow holes 3!) to be formed to permit any overow of ink that may be forced upward between the outer surface of the sleeve and the inner surface of the cylinder.

In Figure 8, the cylinder rests on the bottom of the reservoir and remains there due to its weight; therefore the top end of the cylinder may be spaced from the under side of the cover to provide an annular space 3i to serve the same purpose, and if the cylinder should lift in the lling operation of the cup the upper end of the cylinder will abut the under side of the cover.

In Figure 5, the cup portion is made of soft vulcanized rubber and a suction cup 32 is formed integral therewith which serves to position the cup portion and to hold it in xed relation with the bottom of the reservoir.

To those skilled in the art to which this invention pertains, it will be obvious that many changes in details of construction may be made without departing from the invention disclosed herein, such as changes in form and relative dimensions, and in materials used.

Having thus described my invention I claim as new:

1. An inkstand comprising a reservoir for ink, a cup portion the lower end of which is permanently closed, and means for reducing the atmospheric pressure in the cup portion to cause ink to ow from the reservoir into said cup portion.

2. An inkstand comprising a reservoir for ink, a cup portion having an ink-cup formed therein, a sleeve extending over the cup portion with its lower end resting near the bottom of the reservoir in open communication therewith and its upper end extending above said ink-cup, and means comprising a closure for the upper end of said sleeve for reducing the atmospheric pressure within said sleeve by its upward movement when its lower end is immersed in a liquid.

3. An inkstand comprising a body portion having a reservoir for ink and a cup portion supported therein, an open ended sleeve extending over said cup` portion with its lower end resting adjacent to the bottom of the reservoir and its upper end resting adjacent to the upper end oi said cup portion and. formed to support a penholder which serves as a closure for the said open end; the construction being such that when a liquid is in the reservoir it serves to seal the lower end of said sleeve and when said sleeve is raised the liquid will flow upward from the reservoir to said ink-cup.

4. An inkstand comprising a body portion having a reservoir therein, a cup portion therein having an ink cup formed in its upper end, a sleeve extending over said cup portion which is open at both ends, and means for closing the upper end of said sleeve to provide an air-tight chamber when a liquid is in the reservoir and serves to close the lower end of said sleeve.

5. An inkstand consisting of two parts, a body portion having a reservoir formed therein and a cup portion having an ink-cup formed therein and connected to the body portion in integral relation, and a cover for the reservoir having a depending sleeve which extends downwardly over said cup portion to near its lower end.

6. The construction dened in claim 5, together with said reservoir being formed with an annular depression in which the lower end of said sleeve normally rests.

7. An inkstand comprising a body portion having a reservoir for ink formed therein, a cup portion having an ink-cup, a sleeve extending over said cup portion the upper end of which is adapted to be closed to form a closed chamber and the lower end of which is adapted to be closed by ink in the reservoir; the construction embodying a passage leading from the reservoir to the inkcup thru which ink flows from the reservoir to the ink-cup when the sleeve is raised.

8. An inkstand comprising a body portion having a reservoir for ink, a cover for said reservoir having a depending sleeve and formed with a closed chamber above the ink-cup; the construction being such that the upward movement of said sleeve relative to said ink-cup will increasev the cubic capacity of said chamber.
