INKSTAND.

APPUCATION FILED AUG. l0. 1915.

Patented Mar. 26, 1918.

To all whom t may on/cem.' l i' Be it known that 1,- FREDRICK H. mme

citizen of Canada, residing at Gardner, in

ithas particular reference to that class of v ink vstands which are equipped withv a well communicating with a source of supply of such a nature that the ink in the well will be maintained at a constant level.

The object of the invention is to produce an ink stand of this class in which the channel or duct whereby the well communicates with the source of supply will be so arranged as to constitute an air inlet which will always be open for the passage of an' to replace the ink drawn from the source of supply.

A further object of the inventlon is to 'simplify and improve the valve whereby the reservoir constituting the source of supply communicates with the duct and through the latter with lthe well.

With these and other ends in view which will readily appear as the nature of the in. vention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will bel hereinafter fully described and particularly pointed out in the claim.

In the-accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the recise structural details ytherein exhibited,

ut that changes, alterations and modilications within the scope of the claim may be resorted to when desired.

The body 15 of the improved ink stand may be constructed of glass or other suitable material, and it consists of a block of substantially rectangular shape having near one end thereof a recess 16 constituting the well and near the other end a relatively shallow recess 17, the lower end or bottom portion of which communicates `with the well through a duct-or passage 18 which latter terminates at a distance above the bottom of the well 16. The duct 18 is preferably quite narrow, but of relatively great height, as will be best seen in Fig. 5 of the drawing.

The reservoir which has been shown at 19 is in the nature of a bottle or receptacle havin a short neck 2O which has been shown as being externally threaded for the reception of a tightly fitting cap 21 through which extends a tube 22 having at one end a port or seat 23 for a spring actuated valve 24 'carried loy a stem 25 which is surrounded by the coiled actuating spring 26, one end of the latter abutting on the valve and the other end on an inturned flange 27 of the tube 22. The stem 25 is made to project beyond the ported seat 23, as will be seen in The dregs or sediment. will remain in theA neck of the 4reservoir around the casing and will not pass into the casing. Clogging of the passages is thus prevented.`.

In assembling ,the parts the cap 20 is applied to the receptacle 19 with the valved portion projecting Aoutwardly therefrom, so that the receptacle may be inverted without spilling the ink. The receptacle is then placed on the body 4portion of the stand with the neck 20 extending within the recess 17, the parts being so arranged that when the receptacle is thus applied the projecting end of the valve stem will impinge on the bottom portion of the recess 17, thereby forcing the valve against the tension of the spring 26 suliiciently to permit the ink to iow through the tube 22. As the ink iow's it will be replaced by air entering through the duct 18, which latter is so proportioned and arranged with respect to the valved tube 22 that the valved portion of the latterwill be positioned below the top wall of the duct. It follows that when the level of the ink reaches the mouth of the valved tube, there` tid b stop ino' the flow, an air assa e will styill exislt between the ink in thepductg18 and the upper wall portion of said duct, thus permitting air to freely enter through the Well and duct as the level is lowered in the well by use, evaporation or other causes. To prevent undue evaporation a swinging cover 28 is provided.

The improved ink stand, as will be seen from the foregoing description, is capable of being produced at a moderate expense.

Having thus described the invention, what In an inkstand of the class described, the combination with a base member having a shallow recess, a relatively deep well, and a duct communicating at one end with the shallow recess and at the other end with the well above the bottom of the latter, of a reservoir having a short neck, a cap tightly tting said neck, a tubular housing extending through the cap and into said reservoir the length of the neck and having a ported seat at its outer end and an inturned flange at its inner end, a stem extending through the tube and having a valve housed therein and en aging the seat, and a sprin coiled about t e stem Within the housing between the valve and the iturned flange; the neck of the reservoir being adapted to be disposed within the shallow recess in the base and the outwardly projecting end of the valve stem being adapted to engage the bottom of said recess to unseat the valve, the extension of said tubular housing into said reservoir preventing the draining of sediment from the reservoir into the valve housing.
