TO ALL WHOM IT MAY OONCERN:

Be it known that'I., GEORGE MERRI'TT, of the city of Brooklyn, county of Kings, andlState of New Yori, have invented certain new and useful Improvements in Inks'tands; and I do hereby declare that the following isa full and exact description thereof.

I will first describe what Il consider the best means of carrying outpny invention, and will afterwards` designate the points which I believe to be' new therein. The accompanying drawings form a part oi' this specification. I

Figure `1 is a longitudinal section.

Figure 1 is a'horizontal section across the 'filter-plug and thc funnel.

Figure 2 is a. corresponding section, with thc ink raised.

Figure 3 is a plan view.

Figure (l shows the orifice for illing, with the covering removed.

Figure 5 shows the covering inverted.

Figure 6 shows a modification of the covering.

Figure 7 is a top vie-w oi' the flexible diaphragm.

Similar letters of reference indicate corresponding parts in all the figures.

Tintsare'employed merely to aid'in distinguishing parts, and dovnot imply differences of material. The

I naterial of the body may be glass, and the additional parts may be; brass and India rubber.

A is the main body, and Al isthe dipping-funnel. This latter is'f'ormed in one piece with the main body, A, and it extends down through the latter nearlyto the bottom, as indicated in tigs. 1 and'2. 'A2 is the orifice, through which ink is introduced to replenish the inkstand, at long' intervals. It is covered by an elastic cap, B, of vulcanized India rubber, or analogous material, which is raisedand lowered,4 as required, to induce a corA responding reverse movement in the ink in the funnel A.

Figs. l and 2 represent thc cap B as arranged for what is called the jump, that is to say, the cap is pressed down, and its dome-like position is reversed, andlit is maintained in that position by its own elasticity, when it lis desired to raise the ink in thefunnel A1, iig. I-showing thcjump raised, and fig. 2 showing it in its depressed position. This'is a movement familiar to manufacturers of what are known as .fountain-inkstands, but the means by which my jump is attached is novel, and inv/elves peculiar advantages.

Cis a ring of metal,"-having an internal fiange at its lower end, and adapted to lock under the collar a', as represented. Figs. 4 and 5 show the construction of these parts, and their mode of locking together'.

The outer surface of the ring C is threaded, and adapted to match to the'internal threads on the superior ring D. This ringD has an internal lango at its upper edge, as indicated, and this latter presses down forcibly upon the vulcanized rubber or an'gc of the India-rubbcrjump. ,In order to apply the parts together, the ring C is first applied, and then the jumpis laid in place, and finally thc ring Dis laid upon the whole, and screwed down. The screwing together of the rings D and yC confines the jump and all the parts very firmly. When it is desired toirexnove the jump to introduce ink, it is only necessary to unscrcw the ring D from the ring C, and 'thejump is readily removed, and the aperture A2 is lthen exposed, to allow the introduction of a fresh supply of p ink into the inkstand.

- Figures 6 and 7 represent a modification, whcre,instead oi" 'a jump, a cap of India rubber isl raised and lowered, as required, by the aid of a. screw. 'lhc screw E is tapped through the boss in the framework, B1, on

the top of the ring D. The lower end of the ring D is adapted to turn frcelyin a metal plate, G, secured in thc top of the rubber cap H, by extending the latter up through holes in the plato, and causing it to be enlarged therein, so as to' hold in the manner of a rivet. It will, ofA course, be readily understood that there may be a large number of these rubber rivets, so to speak, and that they may be distributed very uniformly over thc whole surface. The rubber Abeing introduced and held therein in a suitable mo'nld,'while na soft state, is vnl vcanizcd in place.

Fig. 6 is a vertical section of these parts entire, and fig. 7 is a plan view ot' the rubber cap H and metal plate G- alone. The rubber rivets are indicated by g in both of these gnres. The hole in the plate G, which receives the screw E, is not circular, but is extended outV one side from vthe centre, and is there lodgedl sufficiently to allow tho easy introduction of the head or lenlargement of the screw at the lower end. The head being introduced through this hole, the screw is then moved `readily inward, ,until it reaches the centre of the plate G, where it then stands, and operates inthe part of the hole which is 'only of suicient size to allow the neck to turn freely. It there operates in the same manneras if the hole were circular, and of thesame diameterl as the neck of the screw.

The main body, A, andthe funnelB are formed in one piece', at a single operation, by pressing in moulds and blowing, in the manner familiar to glass-workers. y Y

Mis what I term a filter-plug. It is formed of glass, and nearly stops the lower portion of the funnel, A1, but the sides of the plug are groovcd, as indicated by mso that there are suiicient channels for the Vink to run.' [n the absence of some such check, there is a. liability that the jump may force the ink up so rapidly as to throw .t out, and thus to damage articles in the vicinity= especially when operated by an inexperienced person or child. But my filter-plug, M, by checking the velocity ofthe motion ot the ink, and allowing it to risefslowly through i. number of small apertures along'the side of the funnel, renders it impossible to produce such ajresult, however .'iolently the jump may be operated. l 4

The pen-rack P is llocked upon the body-lA of the inlrstand, by lthe elasticity o'f its sides, I1 P2, in the manner indicated. One side ofthe part P is extended,and adapted to forma pen-rack. The other side seizes and :linge around the funnel A1, as indicated in dotted lines in figs. 1 and 3, and thereby holds it in a fixed position,

rnd forms a hinge, 7*,.on which turns the collar R, which 4protectsthe funnel lfrom dust and evaporation when'` :he inkstand is not in use. l

Having new fully described my-inv'ention, what I claim as new,V and desire to secure by Letters Patent, is

Ls follows: v

1. I claim the filter-plug M, in combination with the funnel Al, andwith the jump H, arranged to `operate .uhstantially as and for the purpose herein set forth. j

2. I claim theiduplicate collars C I), threaded, the one male and the other female, as shown, and arranged 'elatively to eaeh other and the neck of the orifice A2, and to the jump H, or equivalent means of raising and owering the pressure ofthe air in the ink'stand, substantially as and for the purposes herein speeitied.

3. I cla-im the pen-rack, P I1 P2, arranged to lock, by its elasticity, upon the main body of the inkstand, md to form a hinge for the'cover R, substantially as herein set forth.
