lMPROVEMENT IN MOLASSES-FAUCETS.

Specification forming part of Letters Patent No. 40,029, dated September 22, 1863.

To all whom it may concern.-

Be it known that we, JOHN FAHRNEY and SAMUEL FAHRNEY, of Washington county and State ot' Maryland, have invented a new and useful Apparatus for Drawing and Measuring Mol-asses or Sirup; and we do hereby declare that the following is a full and exact description thereof, reference being had to thi accompanying drawings, and to the letters ot' reference marked thereon.

Similar letters in the several lgures refer to corresponding parts.

Figure l is a side view of the apparatus, with a section of the front walls of the cylinders D E removed, for the purpose of showing their interiors. Fig. 2 is atop view of the pipe A with its circular plates B O and openings N O P through the upper wal] of said pipe. Fig. 3 is a side view of the crossbar H, showing the position of the sliding rod u and thumb-screw o.

This apparatus consists of a horizontal cast-iron pipe, A, with two circular plates, B O, appended to and cast with its upper surface. These circular pla-tes serve as floors and bottoms for two vertical hollow sheet-tin cylinders, D E, the former being closed at the top and the latter open. In eylinderE moves a piston, F, whose rod G has a cap or head formed on its lower end, which plays in a corresponding.excavation in the cap of the piston, as indicated by the dotted lines a. Said piston-rod has a screw-thread cut upon it throughout its whole length, which'works in a corresponding female thread iu the crossbar H, through the center ot' which it passes. Said crossbar rests upon the top ot' cylinder.A E, held in position by small projections from the same and by a screw-rod, b, from each of its proj ectin gends, passingthrough the win gs of plate O,which also secures the air-tight fitting of the cylinder on the plate. -Upon the screw pistoirrod G is a regulating screwnut, I, beneath which is another similar one, J for the purpose ot' fixing it when set. By the crank K the piston-rod is revolved and motion given to the piston. The dotted lines c indicate the position. ot' a vertical hole through the piston F, into which is fitted a plug, d. The bore of pipe Ais in two sections, L M, indicated by dotted lines ef in Fi g. 1, intersected by circular. openings through the upper wall of the pipe, as indicated by v dotted lines g and shown at N O P in Fig. 2.

Over openings N P are placed heavy valves Q R, closing air-tight upon beveled lips projecting from the margins of said openings. The cylinder or valve-chamber D is secured to its floor air-tight in a similar manner to that of cylinder E by screw-rods h. Both said cylinders rest upon gum-packing, laid in the circular grooves l 2 in plates B O, Fig. 2. With valve-chamber D is connected a piston stop-cock, S, the piston and its rod being indicated by dotted lines z'. The open end of pipe A is a' little conical and has a iine screwthread cut upon it. Into this end of the pipe is inserted the open end of a tin pipe or tube, T, with perforated walls. Through a vertical hole in the cross-bar H a rod, u, capped at its upper end, is fitted loosely, and near the said hole is placed a regulating thumb-screw, V, with a projecting shoulder, as shown at k in Fig. 3.

Operation: To use this apparatus screw the the pipe A rmly into the tap-hole of" the vessel containing the molasses or sirup. Now,

revolve the crank K and sink the piston F asr far as it will go and cover the upper surface of the same with a layer of molasses about one-fourth of an inch thick, for the purpose ot' perfecting its air-tight operation. Next raise the piston F until the nut I stops against the crosslbar H. As the piston thus rises the valve R opens and the molasses follows the piston in the cylinder beneath it. Next dra-w up the piston of the stop-cock S and remove the plug d. Now, reverse the motion ot' the crank, and as soon as all the air has escaped through the hole c in the piston, (the air which remained between the molasses below and the lower surface of the piston,) replace the plug d permanently, and continue sinking the piston until it stops against the valve R and push down the piston of the stop-cock. As the piston F thus sinks the valve R closes, and the molasses in cylinderE enters opening O into the pipe, passes through opening N, raises valve Q, enters valve-chamber D, thence. it Hows into the stop-cock S and out ot' the mouth ot' the same. The current of themolasses is also indicated by the arrows in Fig. l0. The apparatus being thus prepared, all that is necessary to draw exactly one quart of molasses at a single operation is to revolve the crank R until the nut I stops ag-ainst the cross-bar H, next draw up the' piston of the stop-cock, now reverse the motion ofthe crank until the piston F stops against valve It and push down the piston of the stopcock.

To draw 2L pint at one operation7 the projection on the thumb-screw c must be turned so as to cover the top or cap of the sliding rod u. When this is done, raise the piston F until it stops against the lower end of the sliding,` rod, which will be prevented from' sliding upward, as usual, by the projection 7c on the thumb-screw. The piston being` thus stopped at half its usual hei ght, there will be exactly half the usual quantity drawn at one operation. The perforated tube T serves as a filter to prevent anything from passing` into the pipe that might prevent the proper action of the valves.

What We claim as our invention, und desire to secure by Letters Patent, is-

1. The combination and arrangement of the pipe A, cylinders D E, valve R, piston F,open ing 0, and valve Q, as described.

In combination therewith the stop-cock S, as described. v

3. In combination with cylinder E, the valve R, opening O, piston F, with the plug d, the

screw-rod G, and crank K, as described.

4. The combination of the piston F, pistonrod G, cross-bar H, thumb-screw o, and sliding,` rod u, as and for the purposes described.
