Letters Patent No. 94,113, dated August f4, 1869; reissue No. 3,964, dated ltlay 10, 1870.

IMPROVEMENT IN MANUFACTURE OF-INKSTANDS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all persons to whom tltese presents may come:

Whereas Letters Patent No. 94,113, dated August 24, 1869, have been granted to the undersigned, THOMAS SMITH HUDSON, of East Cambridge, of the county of Middlesex and State of Massachusetts, for a new and useful Improvement'in .the Manufac- 'ture of Inkstands; and whereas the `undersigned has petitioned for a reissue of such Letters Patent, to

correct a defect or defects therein, now, therefore, I, the said HUDSON, do hereby declare my said inventionto be more fully described in the following speciiication, and represented in the accompanying drawings.

The said inkstand is of the class usually known under the term of barometer or pneumatic inkstands, it having an air and liquid reservoir, dome, or` fountain, closed at top, and opening at bottom into a. well or cistern, provided with a -iilling-throat or orifice, having a cylindrical extensiou'to receive the collar of a cap, there being an open space between such extension and the dome. The charge of liquid for the well and fountain is to be poured into thel orifice in order, and .when it may be necessary, to supply thev inkstand with ink. A

The article as made in accordance with my invention will, sufce as a mucilage-receiver or stand, it

being of glass, in one entire piece. employed for other useful purposes.

O'f the drawings above mentioned- Figure 1 exhibits a top view;

Figure 2, a side elevation; and

Figure 3, a vertical section of such article.

The latter figure represents, in dotted lines, a tubu lar extension of the walls or sides of the cistern or well of the inkstand, such extension, for the purpose of making the bottom of the cistern or well, being heated, and subsequently contracted or closed iu all around it to a central point. f

Prior to my present invention it has been custom- It may also be 'ary to make the bot-tom of the cistern of a separate piece of glass, and afterward insert lit in the open end or lower part of the cistern, and connect the two at the periphery of the bottom by a process well known to glass-workers. .v

In constructing my improved inkstand I avoid the separate bottom, and the disadvantages and-expense attendant in making it and tting it to the walls of the cistern, and I accomplish the making of the bottom by a tubular extension of the walls of the base, cistern, or well, and by subsequently contracting the said extension and closing it together.

The iukstand, as it is made prior to the construction and closing in of the extension,I term the blauk, it being usually cast or formed by means of amold, consisting of a matrix and a plunger, suitable for the purpose.

base-well or cistern, b l) being the walls or sides of v the base.

The cylindrical neck for reception of the collar part o of the cap C is shown at n, as wholly insulated from the part A, so as to enable the circular cap C and the part 0r collar n thereof to be used on the-opening B without any restraint from the dome A.

The article as molded has a tubular extension, d, the body of glass being rst pressed by a plunger into a mold, of the shape necessary to form the article or blank, not only with the fountain A, the cap, neck, or extension n, and the dipping-orifice or filling-opening B, made partly in such neck, but with. the tubular parts b and d necessary to the formation of the sides and bottom of the base-well or cistern a.

The molded blank, after having been removed from the mold, may be supported in or by a suitable block or device, usually termed a foi-mer, after which the part destined to form the bottom of the cistern should' be heated to the proper temperature, and next should be contracted into, or nearly into a plane, and closed at or near the middle of the article, so as to form the intended bottom, as shown at e.

Iam aware that the bottoms and other parts o inkstands, or other articles of glass, have been made in separate pieces, and. subsequently been united together with glass joints. To the invention of such amethod of manufacturing an inkstand or other article, I herein make no claim.

In my present inkstand, the cistern or part b constitutes a base for the support of the article, such base being cylindrical or prismatic in shape, and havidpg a diameter larger than those of the fountain and ipping orifice combined.

necessary to my present inkstand.

Nor doIclaim a glass inkstand as made with a dome, and a dipping-orifice, and awell or cistern, all

formed by being blown into a mold, and having the blow-hole subsequently closedyby contraction together This renders a metallic stand, such as other barometer in kstauds have, un-

of the dipping-opening, the same rendering it dilow vessel, closed at top and bottom, and having a tubular nose or dipping extension yprojected from one side of such vessel.

Nor do I claim a. glass inkstand,fas represented in the United States Patent No. 7 6,792, dated April 14, 1868, and granted to G. Merritt, wherein lthe body ofthe inkstand is made of glass, with an opening in the top of the dome portion thereof; for the-dome part of my inkstand is made wholly of glass, and 'with no opening except at its bottom,

Furthermorqthe main body and funnel of Merritts are formed in one piece by a single operation, 'by pressing the glass in molds, and blowing in a man- 11er 'familiar to glass-workers. His is a blown inkstand, an article totally di'erent from mine, as glassworkers will readily perceive.

What I claim as of my invention may be stated as follows:

bottom by being heated and contracted, in manner substantially as specified, the whole being in one piece of glass.
