IMPROVEMENT IN INKSIANDS;l

TO ALL WHOM IT MAY OONCERN:

Be it known that we, STEPHEN Pnnn'r and JosEPH'JoHN PER-RY, both of Red Lion Square, London, England, manufacturers, have invented certain new and useful Improvements in IukstandsfV and we do hereby declare that the following is a' full and exact description thereof, reference being had to the accompanying sheet of drawings and to the lettersV of reference marked thereon.

The said improvements consist ohiey in the employment of a hollow stopper, of vulcanized India rubber, or other' suitably elastic material, which is tted in an aperture in the top of the inkstan'd, and which, when forced inward, compresses the air andcauses the ink to rise in a tube, whose upper end terminates in a cup or mouth-piece, into which the pen is dipped. llhesaid tube and cup may b e made solid with the inkstand and` may be arranged at the side of the stopper, or a separate: tube of glass or other suitableA material, may be inserted through thecentre of the stopper. In either case the tube must extend vnearly to the bottom of the inkstand, so thatthe compressed air cannot escape through the said tube without causing the ink to rise. The cup, stopperand tube may also be formed in one piece, the two latter being of soft rubber, and the cup being hardened or strengthened. by a ring of metal, wood, or other hard or inflexible substance.

Description. of the Drawings. l j

Figure 1 is a plan of the top of an inkstand with the tube and dippingfcup formed solidly thereon.l

Figure 2'is a section ofthe same on the line :e x.

Figures 3 and 4 are a similar plan and section of an inkstand, with a separate tube fitted into the stopper,

rFigures 5 and 6 are like views of an inkstand, with stopper and tube formed of'one piece of rubber.

Figure 7 represents a modification ofthe same, and

Figure 8 represents a stopperprovided with a flexible tube.

Like letters indicate the same parts in each of the figures.

The reservoir or body A of the inkstands may be made of earthen-ware, porcelain, glass, or other suitable material, `and may be bf anyr desired form and size. .In the inkstand represented in iigs. 1 and 2, the aperture B for the stopper C is, by` preference, formed with the neck or collar a, to give silicient bearing surface to insure a perfectly air-tight joint between the said aperture and stopper, at whatever position the latter may' be adjusted. The parallel portion ofthe stopper which ts the said aperture is made hollow, the `thickness of the material being just suicient to give it the required stiffness, without impairing its elasticity or exibility. The headl C ofthe stopper C is made solid, to render thesame sniiiciently rigid to be conveniently adjusted.

i When the reservoir A is partially filled with ink, and the stopper C is `introduced into the aperture B, air is enclosed in the space in the reservoir' above the surface ofthe ink, and the slightest compression of this 'air will cause the ink to rise in the tube D.. The stopper C can 'be adjusted to cause the in k to rise to any desired height in the cup D1, and this will be' the ease however small the quantity of ink in the reservoir, provided it is suiioient. to cover the lowerV `end of the tube D. By raising or withdrawing the stopper C slightly in its aperture, the ink'will descend in thetube D, and will remain in that position till the stopper C'is again depressed The ink is by this means saved from evapora-tion, and is kept in good condition tlillit is all used.v

In themodified arrangement'ot` parts representedvin gs. 3 and 4, the tube lll-which passes through the stopper C, is by preference made of glass. The said tube is formed with a'protuberance or enlargement D, just below the cup D, which protuberance fits tightly'in the aperture in the stopper C, und yet allows the said tube to be removed therefrom when desired. With the exception of the central perforation for the reception of the tube D, the said stopper is made the sameas that shown in figs l and 2, and is fitted to slide lair-tight in the aperture'By of the inkstand. When this stopper is depressed in the said aperture, the link rises'into the cup D1, and can be maintained'at any desired height therein, or allowed to sink back into the interior of the inkstand by adjusting the stopper C, as already described. v v i Figs. A5 and drepreseut the stopper C and cup Dhformed in one piece, the stopper being of soft rubber' und the cup of hardened rubber. The tube D is in thiscase dispensed with,.the central portion of the stopper C, which is lengthened for the purpose, serving instead of the said tube. Fig. 8 represents a modification of this mode ot construction. Instead of using the tube D, a tube, E, of India rubber, or other flexible material, may be attached to a short tube on the bottom ofthe cup D1, as shown in 'g. 8 The lower end of this iiexible tube rests on the bottom of the reservoirA, and allows the inkstand to be used with' very little ink in the said reservoir.

What jve claim as our invention, and desire to secure by Letters Patent, is

1. The employment of a hollow stopper, formed of vulcanized India rubber, or other suitable elastic mate rial, in combination with the reservoir A, tube D, and cup D1, for the purpose and substantially in the manner set forth.

2. The tube D, formed with the protuberance D2, and fitted into the stopper C, for the purpose and sub-` stantia'lly in the Imanner set forth. 1

Forming a stopper, cup, and tube,v in` one piece, of hard and soft rubber combined, substantially as described.A
