Speciiication forming part of' LettersPatentfNo. [S9-209, dated April 3, 1877; application filed Y I' f" I February 24, 1877 Figure l of the drawings is a representationof a central .vertical-section of my supply ink-Wells; and Figs. 2, 3, and 4are detailviews of the same. Fig. 5 is a side View (part sec tional) thereof.

The object of this invention is'toxprovide Vconvenient devicesfor filling inkstands from a protected reservoir, and` emptying` said stands into the same. This object is effected by the combination, with an ink well or reservoir, of aA screw-.operated piston or follower and a system of pipes 4leading to the different inkstands, as hereinafter set forth.

In the accompanying drawings, A designatesan ink well or reservoir, which is upright and cylindrical in form, having its upper end open. Said reservoir Ais inclosed in a protecting jacket or casing, B, which rises above it and supports a cover, B. Said cover is centrally perforated at b, and has also smaller perforations b' b on opposite sides thereof. O designates a metal block dovetailed into the top of said cover, as shown in Fig. 3, and eX- tending across the same. Said block is screwu tapped at c and perforated at o c', to correspond with said perforations b b' b'.

D designates a screw-threaded rod, which Works through said screw-threaded central perforation c, and is operated by turning a milled head or disk, D1,.xed on its upper end. Said cover B and block G are secured to said casing B by means of milled nuts d d, which are screwed home upon screw-threaded rods or bolts d', that pass upward through perforations b and c', above described. The lower ends of said rods are secured to said casing B.

The lower end of adjusting-rod D is provided with a piston or follower, E, which works up and down in ink well or reservoir A,'and

is constructed as hereinafter described. When the said piston or follower is depressed by the action of said screw-threaded adjusting-rod it .forces the ink slowly' out of said reservoir g through an opening, a., at the bottom thereof, into a vertical passage or tube, F, Fig. 5,

which may be formed in one piece with reservoir A, or separately, as preferred. From said passage F the ink flows into a distributing pipe, (Eq-connected to said passage by elbowcoupling G. Said distributing-pipe is pro; vided Witha number of small branch pipes, H H,4 as shown in Fig. l, which are, preferably, vertical,'and pass up through the respect- 'ive desks'to ink-stands I. Each one of said v.inkstand's has a small horizontal ingress-pas' jsage, i, which'communicates with the upper end of its tube H. This communication may -be cut off or allowed to remain, at pleasure, by .turning a small cock, J,which has near its' lower end a way, j. Said cock works in avertical cylindrical seat or space in said inkstand. Where only a single desk is to be supplied with ink a form of inkstand without cock may be used, similar to that shown in Fig. 5. Several distributing-pipes, Gr, may be used instead of one, when such an arrangement is more convenient.

The piston or follower E consists of a bottom disk, E1, preferably of glass, a sectional upper plate, E2, and a series of interposed layers of rubber or other packing, E, which serve to keep the contact of said follower with inkwell Aair-tight.' Said' sectional upper plate E2 is provided with an upward tubularvextension, e, and dividedvertically. Said sectional tubulaiextension is screw-threaded on the outside, and held together by a screw-tapped `closed at top and bottom. In said chamber sets a small cylinder or fixed collar, D2,on the lower end of screw-threaded rod D, also a similar collar or head, e3, on the upper end of a shank, E3, attached to disk El. The

above-described construction of said piston or follower makes it as firm as if manufactured in a single piece, while Vallowing all its parts to be readily separated for convenience in cleansing or other purposes.

When the said piston or follower is drawn up by the operation of screw-threaded rod D,

rrrcn.

the ink is drawn back into reservoir A by the vacuum thus created and the pressure of the external air. This completely empties distributingpipe G and so many ot' the inkstands- I as are then in communication therewith. The casing B and top B', being of material which does not conduct heat well, will then protect the ink from freezing.

By'using this invention the accumulation of sediment in inkstands is almost entirely prevented, as they are frequently emptied, and

" the escaping current through their bottom openings cleanses them of all impurities. Water may also be forced in and out for this latter purpose by operating piston E. This invention also economizes time in filling and emptying the inkstands, and withdraws the ink from all contact with the atmosphere, whereby it is speedily deteriorated on account of evaporation and the deposition of dust, &c.

My inkwe1l is especially suited to be used in school-rooms, or wherever else many persons are engaged in using ink at the same time. The independent cock-connection of the differ` ent inkstands to the distributing-pipe makes it possible to' fill anyone or more` of said stands without filling the remainder, or to leave one or more still full after school-hours or office-hours, when the others have been emptied.

rlhe parts of said apparatus which come incontact with the ink may be made of any substance which will not be injured thereby. Passage F should be iuclosed within casing B. L

What I claim as new, and desire to secure v by Letters Patent, is- Y y 1. The combination of an ink-reservoir, with a follower workin g therein, and a distributingpipe leading to several different inkstands, substantially as and for the purpose set' forth.

2. Non-conducting casing B and head B', in combination with ink-reservoir A and vertical passage F, substantially as and for the purpose set forth.

3. The combination of screw-tapped block C and screw-threaded rod D with piston or follower E, well A, tube F, and distributingpipe G, substantially as and for the purpose set forth. l

4. TheJ combination of distributing-pipe Gr, with branch pipes H,inkstands I, having sepa- 'rate cocks J passage F, reservoir A, and piston E, substantially as and for the purpose set forth. l

5. The combination of screw-threaded rod D, having xed collar D2, with sectional upper piece E2, clamping collar or nut e1, packing E4, land disk El, having shank E3, with a collar xed on its upper end, substantially as andforlthe purpose set fort In testimony that I claim the above I have hereuntosubscribed my name in the presence of two witnesses.
