IM PROVEMNT IN1 sl RUP-G-AGES.

Specification forming part of Letters Patent No. 2011593, dated March 26, 1878; application liled July 2V-1, 1877.

To all whom it may concern: l.

Be it. known that I, JOHN Bann, of the` city of Canton, county of Fulton, State of Illinois, have invented certain new and useful Improvements `in Sirup-Gages, of which the` followingis a specification: i

My invention consists of a force-pump, so`

constructed and ,combined with valves that, byl its movements, it successively supplies a bottle, first, with a measured quantity of one kind of liquid, and subsequently with another kind of liquid.

In theaccompanyin g drawings, making part of thisspecilication, Figure 1 is a side eleva-` tion of a gage embodying my invention, and

Fig. 2 isan elevation of that end of same which is at the right hand in Fig. l. is a.

vertical central section of same, taken at the line XXof Fig. 2.` Fig. 4 is asimilar section of that portion of the device shown at the right hand in Fig. 3, said section being enventingA any liquid from passing 'out of the,-

cylinder. The lower end: d of the cylinder C is screwed ontoythe valve-seat The piston is4 provided at the top with a journal-box, m,- in which is locatedjand` turns the lever M,I

curved at top sufficiently-to clear the gland D,

and'extended down below the length of thel cylinder, and terminated inan eye working'on a round stud or pivot, p, and secured to the stud by a movable pin, n', passed through the stud outside of the eye. The stud is fixed in the projection s', which forms part of an annular collar, s, which revolves on a stationary disk, r, and is held in place by a plate, N, screwed into the disk r, and whose edge overlaps'the edge of collar s. Alever, S, attached to collar s, to the left of yrod M, terminates in ahandle, b, preferably spheroidal.

The amount of revolution t hich the handle is permitted to make is regulated by a pin,a,

in the collars, and a-stub, e, projecting from the under portion of the flange c. Projecting below the portion W is the extension Ii, perf forated with a hole, the lower portion of which 1 latter and the bottoml of portionEis placed a 1 gasket, k2. A gasket, k,is also placed between hanged on cylinder G and flange eon valvef seat W. The4 stufling-box I screws into anc opening` in the top of the valve-seat W.

Through the stuffing-box the valvefstein F passes. Around the valve-stem F and under stuffing-box I is placed stufting o.

Valve Fl is made in two parts, as shown in Figs, 7 andy S,y the valve being inverted in The stem F is provided withr those figures. an enlargement,.4, into which the screw is inserted. .By this arrangement the gasket 3,

is held in place by enlargement 4 and valve head, F. rlhe valve F works in the chamber F", and-is normally held against the top of the chamber F/ by the spring X". ASimilarly the valve YF" is held in position in chamber E by a spring, X. The valve E is madefwith a solidl piece projecting below flange P, and over which extension is passed the springX. The

upper part of valveFil is hollow, and is prof` vided with two openings, h h', diametrically opposite each other, and sometimes with four, as shown by the.:dotteclline, Fig. 5. The small-,valvefEmworks in the hollow part of thevlarg valve E. The lower part of the valve EW is made hollow, and providedv with one or more openings,as shown in Fig. 5,;

preferably as many as can be made with safety to the valve.

The spring X is placed in the hollow of both valves E and E, and holds the valve E against its seat.

Valve F!" is preferably madewith a head, u, and solid stein u', as shown in Fig. 6, in which case spring X surrounds stem u.

The spring X' is not as stiff as spring X, andconsequently does not interfere with its proper action.

v The openings or valve-chambers in the eX- tensions E and L are made of different sizes in different parts of their lengths, (see Fig. 3,) for the purpose of forming valve-seats and accommodating the different sizes of valves. There is a passage, H', connecting the valvechamber of portion E with the cylinder C, and an opening, H, connecting the upper portion of said valve-chamber with a pipe connected with a vessel containing one of the liquids to be pumped. The opening R, passing through both valve-chambers, is the effluent passage and R' the influent passage, of the other liquid. v

Passage R' may enter from the end, as in Fig. 3, or from the side opposite the side shown in Fig. l.

The method of operating the machine is as follows: After making proper connections with the liquids and the vessel to be filled, the lever S is depressed, thereby elevating piston A and forming a vacuum in cylinder C. The pressure of the atmosphere on the liquid connected with pipe H forces the said liquid (which, for convenience sake, will be called the "lirstliquid") through pipe H, forces down valvefE'", as seen in Fig. 3, and passes into the cylinder C. Lever S is now raised, and piston A is thereby lowered, and in descending forces liquid N o. l back through passage H' but as pressure is now removed from the top of valve E'", and spring X' forces it up against its seat, as in Fig. 4, the liquid passes through one of the holes h in valve E'", and down through said valve into valve E', thereby forcing this latter valve down, and ,allowing the liquid to flow into the passage R. As

Apiston lA approaches the bottom of the cylinder it strikes against the.y top of thc valvestem F, lowers valve F', and allows liquid No.2, which is under pressure, and is connected with passage R', to force its way through the passage R, and consequently to mix with liquid N o. l. As soon as a sufficient quantity of liquid N o. 2 has passed through, lever S is lowered, thereby removing the pressu're from valve-stem F, and allowing spring X" to raise the valve F' and cut off the supply of liquid No. 2.

It is evident from this description of the operation that to a certain quantity of liquid No. l (determined by stroke of piston A, regulated by pin a and stub e) any desired quantity of liquid No.` 2 maybe added.

purpose are only force-pumps, and consequently the liquid No. l is necessarily placed in a reservoir above the pump, while with my pump the reservoir containing liquid No. 1

can be put in any convenient place in the' vicinity.

Second. In my gage there is but one working joint which comes in contact with the liquid, and this joint is at the stuffing-box on the top of the cylinder, and hence there is very little liability to leak; but the other gages now in use are veryleaky after short wear.

Third. In my pump the solid plunger is used, thereby avoiding packing both the rod and piston, and merely necessitating the easier operation-of packing the rod.

Fourth. 'In my pump the pitman working the piston is bent over the top of the pump, and connects directly with the piston-rod, and avoids the two joints used in other gages, and consequently simplies the construction. Moreover, having but one joint here, there is less lost motion and less jar in my pump than in pumps of other gages now in use. What T claim as new, and desire to secure by Letters Patent, is-

1. Valve F', combined with spring X", pisgm A, valve-seat, as W, and spring-seat, as

l2. Valve E', constructed as described, and combined with spring X, valve-seat, as W, and spring-seat, as N".

3. The combination of valves E and l"' and springs X and X', substantially as set forth.

4. Combination of valve-seat yW, provided with passages R, R', H, and H', valve-chambers, constructed as described, valves F', E', and E'", provided with springs X, X', and X", cylinder C, provided with any suitable piston A, operated by any suitable mechanism, substantially as set forth. v 5. Combination of lever S, handle b, ring s,

disk fr, plate N, curved pitman M, substan-I tial ly as and for the purposes set forth.

6. Combination of lever S, handle b, ring s, disk r, plate N, pin a, stub e, pitman M, substantially as set forth.
